I had the same problem, but it's solved now. Finally, Putty does work with Cigwin-X, and Xming is not an obligatory app for MS-Windows X-server.

Nowadays it's xlaunch, who controls the run of X-window. Certainly, xlaunch.exe must be installed in Cigwin. When run in interactive mode it asks for "extra settings". You should add "-listen tcp" to additional param field, since Cigwin-X does not listen TCP by default.

In order to not repeat these steps, you may save settings to the file. And run xlaunch.exe via its shortcut with modified CLI inside. Something like

C:\cygwin64\bin\xlaunch.exe -run C:\cygwin64\config.xlaunch

Take attention on -e ssh and jenkins@localhost: in next example:

rsync -r  -e ssh --chown=jenkins:admin --exclude .git --exclude Jenkinsfile --delete ./ jenkins@localhost:/home/admin/web/xxx/public

That helped me

P.S. Today, i realized that when you change (add) jenkins user to some group, permission will apply after slave (agent) restart. And my solution (-e ssh and jenkins@localhost:) need only when you can't restart agent/server.

There is a bug https://bugs.php.net/bug.php?id=61045 in php-fpm from v5.3.9 and till now (5.3.14 and 5.4.4). Developer promised fix will go live in next release. If you don't want to wait - use patch on that page and re-build or rollback to 5.3.8.

Couldn't resist throwing this out there, old as this thread is... Usually when the need arises to iterate through each of the files in PATH, all you really want to do is find a particular file... If that's the case, this one-liner will spit out the first directory it finds your file in:

(ex: looking for java.exe)

for %%x in (java.exe) do echo %%~dp$PATH:x

Overview:

• Both Promises and Observables help us dealing with asynchronous operations. They can call certain callbacks when these asynchronous operations are done.
• A Promise can only handle one event, Observables are for streams of events over time
• Promises can't be cancelled once they are pending
• Data Observables emit can be transformed using operators

You can always use an observable for dealing with asynchronous behaviour since an observable has the all functionality which a promise offers (+ extra). However, sometimes this extra functionality that Observables offer is not needed. Then it would be extra overhead to import a library for it to use them.

When to use Promises:

Use promises when you have a single async operation of which you want to process the result. For example:

var promise = new Promise((resolve, reject) => {
  // do something once, possibly async
  // code inside the Promise constructor callback is getting executed synchronously

  if (/* everything turned out fine */) {
    resolve("Stuff worked!");
  }
  else {
    reject(Error("It broke"));
  }
});

//after the promise is resolved or rejected we can call .then or .catch method on it

promise.then((val) => console.log(val))      // logs the resolve argument
       .catch((val) => console.log(val));    // logs the reject argument

So a promise executes some code where it either resolves or rejects. If either resolve or reject is called the promise goes from a pending state to either a resolved or rejected state. When the promise state is resolved the then() method is called. When the promise state is rejected, the catch() method is called.

When to use Observables:

Use Observables when there is a stream (of data) over time which you need to be handled. A stream is a sequence of data elements which are being made available over time. Examples of streams are:

1. User events, e.g. click, or keyup events. The user generates events (data) over time.
2. Websockets, after the client makes a WebSocket connection to the server it pushes data over time.

In the Observable itself is specified when the next event happened, when an error occurs, or when the Observable is completed. Then we can subscribe to this observable, which activates it and in this subscription, we can pass in 3 callbacks (don't always have to pass in all). One callback to be executed for success, one callback for error, and one callback for completion. For example:

const observable = Rx.Observable.create(observer => {
  // create a single value and complete
  observer.onNext(1);
  observer.onCompleted();
});

source.subscribe(
  x => console.log('onNext: %s', x),   //  success callback
  e => console.log('onError: %s', e),  //  error callback
  () => console.log('onCompleted')     //  completion callback
 );

// first we log: onNext: 1
//  then we log: onCompleted

When creating an observable it requires a callback function which supplies an observer as an argument. On this observer, you then can call onNext, onCompleted, onError. Then when the Observable is subscribed to it will call the corresponding callbacks passed into the subscription.

As @Sourabh already pointed out, you can check in the Google Maven link what are the packages that Google has listed out.

If you, like me, are prompted with a similar message to this Failed to resolve: com.android.support:appcompat-v7:28.0, it could be that you got there after upgrading the targetSdkVersion or compileSdkVersion.

What is basically happening is that the package is not being found, as the message correctly says. If you upgraded the SDK, check the Google Maven, to check what are the available versions of the package for the new SDK version that you want to upgrade to.

I had these dependencies (on version 27):

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support:recyclerview-v7:27.1.1'
implementation 'com.android.support:cardview-v7:27.1.1'
implementation 'com.android.support:support-v4:27.1.1'

And I had to change the SDK version and the rest of the package number:

implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'com.android.support:cardview-v7:28.0.0'
implementation 'com.android.support:support-v4:28.0.0'

Now the packages are found and downloaded. Since the only available package for the 28 version of the SDK is 28.0.0 at the moment of writing this.

This is the code I usually use:

string getSubString(string value, int index, int length)
        {
            if (string.IsNullOrEmpty(value) || value.Length <= length)
            {
                return value;
            }
            System.Text.StringBuilder sb = new System.Text.StringBuilder();
            for (int i = index; i < length; i++)
            {
                sb.AppendLine(value[i].ToString());
            }
            return sb.ToString();
        }

I suggest you look into getting composer. https://getcomposer.org Composer makes getting third-party libraries a LOT easier and using a single autoloader for all of them. It also standardizes on where all your dependencies are located, along with some automatization capabilities.

Download https://getcomposer.org/composer.phar to C:\Inetpub\wwwroot\php

Delete your C:\Inetpub\wwwroot\php\PHPMailer\ directory.

Use composer.phar to get the phpmailer package using the command line to execute

cd C:\Inetpub\wwwroot\php
php composer.phar require phpmailer/phpmailer

After it is finished it will create a C:\Inetpub\wwwroot\php\vendor directory along with all of the phpmailer files and generate an autoloader.

Next in your main project configuration file you need to include the autoload file.

require_once 'C:\Inetpub\wwwroot\php\vendor\autoload.php';

The vendor\autoload.php will include the information for you to use $mail = new \PHPMailer;

Additional information on the PHPMailer package can be found at https://packagist.org/packages/phpmailer/phpmailer

The -HideTableHeaders parameter unfortunately still causes the empty lines to be printed (and table headers appearently are still considered for column width). The only way I know that could reliably work here would be to format the output yourself:

| % { '{0,10} {1,20} {2,20}' -f $_.Operation,$_.AttributeName,$_.AttributeValue }

I made this script, It worked for my 10 pandas Data frames

from pyspark.sql.types import *

# Auxiliar functions
def equivalent_type(f):
    if f == 'datetime64[ns]': return TimestampType()
    elif f == 'int64': return LongType()
    elif f == 'int32': return IntegerType()
    elif f == 'float64': return FloatType()
    else: return StringType()

def define_structure(string, format_type):
    try: typo = equivalent_type(format_type)
    except: typo = StringType()
    return StructField(string, typo)

# Given pandas dataframe, it will return a spark's dataframe.
def pandas_to_spark(pandas_df):
    columns = list(pandas_df.columns)
    types = list(pandas_df.dtypes)
    struct_list = []
    for column, typo in zip(columns, types): 
      struct_list.append(define_structure(column, typo))
    p_schema = StructType(struct_list)
    return sqlContext.createDataFrame(pandas_df, p_schema)

You can see it also in this gist

With this you just have to call spark_df = pandas_to_spark(pandas_df)

The job of the DispatcherServlet is to take an incoming URI and find the right combination of handlers (generally methods on Controller classes) and views (generally JSPs) that combine to form the page or resource that's supposed to be found at that location.

I might have

• a file /WEB-INF/jsp/pages/Home.jsp

• and a method on a class

  @RequestMapping(value="/pages/Home.html")
  private ModelMap buildHome() {
      return somestuff;
  }
  

The Dispatcher servlet is the bit that "knows" to call that method when a browser requests the page, and to combine its results with the matching JSP file to make an html document.

How it accomplishes this varies widely with configuration and Spring version.

There's also no reason the end result has to be web pages. It can do the same thing to locate RMI end points, handle SOAP requests, anything that can come into a servlet.

Integer is only there for the sql standard ie deprecated by Oracle.

You should use Number instead.

Integers get stored as Number anyway by Oracle behind the scenes.

Most commonly when ints are stored for IDs and such they are defined with no params - so in theory you could look at the scale and precision columns of the metadata views to see of no decimal values can be stored - however 99% of the time this will not help.

As was commented above you could look for number(38,0) columns or similar (ie columns with no decimal points allowed) but this will only tell you which columns cannot take decimals, and not what columns were defined so that INTS can be stored.

Suggestion: do a data profile on the number columns. Something like this:

 select max( case when trunc(column_name,0)=column_name then 0 else 1 end ) as has_dec_vals
 from table_name

Why don't you create a bat file makedos.bat containing the following line?

c:\DOS\make.exe %1 %2 %5

and put it in C:\DOS (or C:\Windowsè or make sure that it is in your %path%)

You can run from cmd, SET and it displays all environment variables, including PATH.

In registry you can find environment variables under:

• HKEY_CURRENT_USER\Environment
• HKEY_CURRENT_USER\Volatile Environment
• HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager\Environment

#compare 1st half with reversed second half
# i.e. 'abba' -> 'ab' == 'ba'[::-1]

def is_palindrome( s ):
   return True if len( s ) < 2 else s[ :len( s ) // 2 ] == s[ -( len( s ) // 2 ):][::-1]

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

I had a similar problem with a physical device. The problem was related with the fact that the google app ( the search bar for google on top ) was disabled. After the first reboot launcher3 began failing. No matter how many cache/data cleaning I did, it kept failing. I reenabled it and launched it, so it appeared again on the screen and from that moment on, launcher3 was back to life.

I guess there mmust be some kind of dependency with this app.

There are (at least) three different things you might conceive of as a "character", and consequently, three different categories of approach you might want to use.

Splitting into UTF-16 code units

JavaScript strings were originally invented as sequences of UTF-16 code units, back at a point in history when there was a one-to-one relationship between UTF-16 code units and Unicode code points. The .length property of a string measures its length in UTF-16 code units, and when you do someString[i] you get the ith UTF-16 code unit of someString.

Consequently, you can get an array of UTF-16 code units from a string by using a C-style for-loop with an index variable...

const yourString = 'Hello, World!';_x000D_
const charArray = [];_x000D_
for (let i=0; i<=yourString.length; i++) {_x000D_
    charArray.push(yourString[i]);_x000D_
}_x000D_
console.log(charArray);

There are also various short ways to achieve the same thing, like using .split() with the empty string as a separator:

const charArray = 'Hello, World!'.split('');_x000D_
console.log(charArray);

However, if your string contains code points that are made up of multiple UTF-16 code units, this will split them into individual code units, which may not be what you want. For instance, the string '' is made up of four unicode code points (code points 0x1D7D8 through 0x1D7DB) which, in UTF-16, are each made up of two UTF-16 code units. If we split that string using the methods above, we'll get an array of eight code units:

const yourString = '';_x000D_
console.log('First code unit:', yourString[0]);_x000D_
const charArray = yourString.split('');_x000D_
console.log('charArray:', charArray);

Splitting into Unicode Code Points

So, perhaps we want to instead split our string into Unicode Code Points! That's been possible since ECMAScript 2015 added the concept of an iterable to the language. Strings are now iterables, and when you iterate over them (e.g. with a for...of loop), you get Unicode code points, not UTF-16 code units:

const yourString = '';_x000D_
const charArray = [];_x000D_
for (const char of yourString) {_x000D_
  charArray.push(char);_x000D_
}_x000D_
console.log(charArray);

We can shorten this using Array.from, which iterates over the iterable it's passed implicitly:

const yourString = '';_x000D_
const charArray = Array.from(yourString);_x000D_
console.log(charArray);

However, unicode code points are not the largest possible thing that could possibly be considered a "character" either. Some examples of things that could reasonably be considered a single "character" but be made up of multiple code points include:

• Accented characters, if the accent is applied with a combining code point
• Flags
• Some emojis

We can see below that if we try to convert a string with such characters into an array via the iteration mechanism above, the characters end up broken up in the resulting array. (In case any of the characters don't render on your system, yourString below consists of a capital A with an acute accent, followed by the flag of the United Kingdom, followed by a black woman.)

const yourString = 'A´';_x000D_
const charArray = Array.from(yourString);_x000D_
console.log(charArray);

If we want to keep each of these as a single item in our final array, then we need an array of graphemes, not code points.

Splitting into graphemes

JavaScript has no built-in support for this - at least not yet. So we need a library that understands and implements the Unicode rules for what combination of code points constitute a grapheme. Fortunately, one exists: orling's grapheme-splitter. You'll want to install it with npm or, if you're not using npm, download the index.js file and serve it with a <script> tag. For this demo, I'll load it from jsDelivr.

grapheme-splitter gives us a GraphemeSplitter class with three methods: splitGraphemes, iterateGraphemes, and countGraphemes. Naturally, we want splitGraphemes:

const splitter = new GraphemeSplitter();_x000D_
const yourString = 'A´';_x000D_
const charArray = splitter.splitGraphemes(yourString);_x000D_
console.log(charArray);

<script src="https://cdn.jsdelivr.net/npm/[email protected]/index.js"></script>

And there we are - an array of three graphemes, which is probably what you wanted.

Simple example...

Let's say the child view controller has a UISlider and we want to pass the value of the slider back to the parent via a delegate.

In the child view controller's header file, declare the delegate type and its methods:

ChildViewController.h

#import <UIKit/UIKit.h>

// 1. Forward declaration of ChildViewControllerDelegate - this just declares
// that a ChildViewControllerDelegate type exists so that we can use it
// later.
@protocol ChildViewControllerDelegate;

// 2. Declaration of the view controller class, as usual
@interface ChildViewController : UIViewController

// Delegate properties should always be weak references
// See http://stackoverflow.com/a/4796131/263871 for the rationale
// (Tip: If you're not using ARC, use `assign` instead of `weak`)
@property (nonatomic, weak) id<ChildViewControllerDelegate> delegate;

// A simple IBAction method that I'll associate with a close button in
// the UI. We'll call the delegate's childViewController:didChooseValue: 
// method inside this handler.
- (IBAction)handleCloseButton:(id)sender;

@end

// 3. Definition of the delegate's interface
@protocol ChildViewControllerDelegate <NSObject>

- (void)childViewController:(ChildViewController*)viewController 
             didChooseValue:(CGFloat)value;

@end

In the child view controller's implementation, call the delegate methods as required.

ChildViewController.m

#import "ChildViewController.h"

@implementation ChildViewController

- (void)handleCloseButton:(id)sender {
    // Xcode will complain if we access a weak property more than 
    // once here, since it could in theory be nilled between accesses
    // leading to unpredictable results. So we'll start by taking
    // a local, strong reference to the delegate.
    id<ChildViewControllerDelegate> strongDelegate = self.delegate;

    // Our delegate method is optional, so we should 
    // check that the delegate implements it
    if ([strongDelegate respondsToSelector:@selector(childViewController:didChooseValue:)]) {
        [strongDelegate childViewController:self didChooseValue:self.slider.value];
    }
}

@end

In the parent view controller's header file, declare that it implements the ChildViewControllerDelegate protocol.

RootViewController.h

#import <UIKit/UIKit.h>
#import "ChildViewController.h"

@interface RootViewController : UITableViewController <ChildViewControllerDelegate>

@end

In the parent view controller's implementation, implement the delegate methods appropriately.

RootViewController.m

#import "RootViewController.h"

@implementation RootViewController

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
    ChildViewController *detailViewController = [[ChildViewController alloc] init];
    // Assign self as the delegate for the child view controller
    detailViewController.delegate = self;
    [self.navigationController pushViewController:detailViewController animated:YES];
}

// Implement the delegate methods for ChildViewControllerDelegate
- (void)childViewController:(ChildViewController *)viewController didChooseValue:(CGFloat)value {

    // Do something with value...

    // ...then dismiss the child view controller
    [self.navigationController popViewControllerAnimated:YES];
}

@end

Hope this helps!

$('#google').attr('onclick') + ""

However, Firebug shows that this returns a function 'onclick'. You can call the function later on using the following approach:

(new Function ($('#google').attr('onclick') + ';onclick();'))()

... or use a RegEx to strip the function and get only the statements within it.

%timeit is an ipython magic function, which can be used to time a particular piece of code (A single execution statement, or a single method).

From the docs:

%timeit

Time execution of a Python statement or expression

Usage, in line mode:
    %timeit [-n<N> -r<R> [-t|-c] -q -p<P> -o] statement

To use it, for example if we want to find out whether using xrange is any faster than using range, you can simply do:

In [1]: %timeit for _ in range(1000): True
10000 loops, best of 3: 37.8 µs per loop

In [2]: %timeit for _ in xrange(1000): True
10000 loops, best of 3: 29.6 µs per loop

And you will get the timings for them.

The major advantage of %timeit are:

• that you don't have to import timeit.timeit from the standard library, and run the code multiple times to figure out which is the better approach.

• %timeit will automatically calculate number of runs required for your code based on a total of 2 seconds execution window.

• You can also make use of current console variables without passing the whole code snippet as in case of timeit.timeit to built the variable that is built in an another environment that timeit works.

Just put the below simple code :

notification.sound = Uri.parse("android.resource://"
        + context.getPackageName() + "/" + R.raw.sound_file);

For Default Sound:

notification.defaults |= Notification.DEFAULT_SOUND;

This works fine for me:

while True:
   answer = input('Do you want to continue?:')
   if answer.lower().startswith("y"):
      print("ok, carry on then")
   elif answer.lower().startswith("n"):
      print("sayonara, Robocop")
      exit()

edit: use input in python 3.2 instead of raw_input

Another option is to use Qt Jambi. It has nearly all the greatness of Qt (many components, good documentation, easy to use), without the hassle of C++. I used it 3-4 years ago for a small project, even then it was almost mature.

You might want to see the discussion about Swing vs. Qt here.

cd /var/log/nginx/

One way to solve is to give a static factory method to allocate the array if for some reason you want to give constructor private.

static Car*  Car::CreateCarArray(int dimensions)

But why are you keeping one constructor public and other private?

But anyhow one more way is to declare the public constructor with default value

#define DEFAULT_CAR_INIT 0
Car::Car(int _no=DEFAULT_CAR_INIT);

The basic difference between them is that | first converts the values to binary then performs the bit wise or operation. Meanwhile, || does not convert the data into binary and just performs the or expression on it's original state.

int two = -2; int four = -4;
result = two | four; // bitwise OR example

System.out.println(Integer.toBinaryString(two));
System.out.println(Integer.toBinaryString(four));
System.out.println(Integer.toBinaryString(result));

Output:
11111111111111111111111111111110
11111111111111111111111111111100
11111111111111111111111111111110

Just incase u didnt understand

e.g is that lets say i have a JSON STRING ..NOT YET A JSON OBJECT OR ARRAY.

so if in javascript u parse the string as

var body={
  "id": 1,
  "deleted_at": null,
  "open_order": {
    "id": 16,
    "status": "open"}

var jsonBody = JSON.parse(body.open_order); //HERE THE ERROR NOW APPEARS BECAUSE THE STRING IS NOT A JSON OBJECT YET!!!! 
//TODO SO
var jsonBody=JSON.parse(body)//PASS THE BODY FIRST THEN LATER USE THE jsonBody to get the open_order

var OpenOrder=jsonBody.open_order;

Great answers above

Ahhh, that's super simple, no programming required.

See: https://developers.facebook.com/docs/plugins/page-plugin

You'll want to keep the show stream option turned on. You can adjust width and heigth and a few other things.

Because you defined the struct as consisting of char arrays, the two strings are the structure and freeing the struct is sufficient, nor is there a way to free the struct but keep the arrays. For that case you would want to do something like struct { char *firstName, *lastName; }, but then you need to allocate memory for the names separately and handle the question of when to free that memory.

Aside: Is there a reason you want to keep the names after the struct has been freed?

To use video extensions that are MKV. You should use video, not source

For example :

  <!-- mkv -->
  <video width="320" height="240" controls src="assets/animation.mkv"></video>
<!-- mp4 -->
  <video width="320" height="240" controls>
    <source src="assets/animation.mp4" type="video/mp4" />
  </video>

To encode mp3 audio ffmpeg.org shows the following example:

ffmpeg -i input.wav -codec:a libmp3lame -qscale:a 2 output.mp3

I extracted the audio from a video just by replacing input.wav with the video filename. The 2 means 190 kb/sec. You can see the other quality levels at my link above.

If you just want to see if it's present, try turning the list into a dict:

# Generate a list
l = [n*n for n in range(1000)]

# Convert to dict - doesn't matter what you map values to
d = dict((x, 1) for x in l)

count = 0
for n in range(1000000):
    # Compare with "if n in l"
    if n in d:
        count += 1

On my machine, "if n in l" took 37 seconds, while "if n in d" took 0.4 seconds.

Reducing the image size before output results in something that looks sharper, in my case:

convert -density 300 a.pdf -resize 25% a.png

Invoke mysql with the -N (the alias for -N is --skip-column-names) option:

mysql -N ...
use testdb;
select * from names;

+------+-------+
|    1 | pete  |
|    2 | john  |
|    3 | mike  |
+------+-------+
3 rows in set (0.00 sec)

Credit to ErichBSchulz for pointing out the -N alias.

To remove the grid (the vertical and horizontal lines) around the results use -s (--silent). Columns are separated with a TAB character.

mysql -s ...
use testdb;
select * from names;

id  name
1   pete
2   john
3   mike

To output the data with no headers and no grid just use both -s and -N.

mysql -sN ...

Another option which hasn't been mentioned is to use which:

length(which(z))

Just to actually provide some context on the "which is faster question", it's always easiest just to test yourself. I made the vector much larger for comparison:

z <- sample(c(TRUE,FALSE),1000000,rep=TRUE)
system.time(sum(z))
   user  system elapsed 
   0.03    0.00    0.03
system.time(length(z[z==TRUE]))
   user  system elapsed 
   0.75    0.07    0.83 
system.time(length(which(z)))
   user  system elapsed 
   1.34    0.28    1.64 
system.time(table(z)["TRUE"])
   user  system elapsed 
  10.62    0.52   11.19 

So clearly using sum is the best approach in this case. You may also want to check for NA values as Marek suggested.

Just to add a note regarding NA values and the which function:

> which(c(T, F, NA, NULL, T, F))
[1] 1 4
> which(!c(T, F, NA, NULL, T, F))
[1] 2 5

Note that which only checks for logical TRUE, so it essentially ignores non-logical values.

Ten years later and using Python 3.7 and Linux there are still different ways to do this:

import subprocess
from pathlib import Path

#using pathlib.Path
path = Path('/path/to/your/dir')
subprocess.run(["rm", "-rf", str(path)])

#using strings
path = "/path/to/your/dir"
subprocess.run(["rm", "-rf", path])

Essentially it's using Python's subprocess module to run the bash script $ rm -rf '/path/to/your/dir as if you were using the terminal to accomplish the same task. It's not fully Python, but it gets it done.

The reason I included the pathlib.Path example is because in my experience it's very useful when dealing with many paths that change. The extra steps of importing the pathlib.Path module and converting the end results to strings is often a lower cost to me for development time. It would be convenient if Path.rmdir() came with an arg option to explicitly handle non-empty dirs.

The first check user logged in and then

if (Auth::check()){
    //get id of logged in user
    {{ Auth::getUser()->id}}

    //get the name of logged in user
    {{ Auth::getUser()->name }}
}

You can make use of cut, sort and uniq commands as follows:

cat input_file | cut -f 1 | sort | uniq

gets unique values in field 1, replacing 1 by 2 will give you unique values in field 2.

Avoiding UUOC :)

cut -f 1 input_file | sort | uniq

EDIT:

To count the number of unique occurences you can make use of wc command in the chain as:

cut -f 1 input_file | sort | uniq | wc -l

Windows:

 java -cp file.jar;dir/* my.app.ClassName

Linux:

 java -cp file.jar:dir/* my.app.ClassName

Remind:
- Windows path separator is ;
- Linux path separator is :
- In Windows if cp argument does not contains white space, the "quotes" is optional

Following can be an approach

   SharedPreferences se_get = getSharedPreferences("points",MODE_PRIVATE);
   Set<String> main = se_get.getStringSet("mydata",null);
   for(int jk = 0 ; jk < main.size();jk++)
   {
      Log.i("data",String.valueOf(main.toArray()[jk]));
   }

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

if (HttpContext.Current.Request["MYCLICKEDBUTTONID"] == null)
{
   //Do not reload the gridview.

}
else
{
   reload my gridview.
}

Right click project solution

Properties -> Configuration Properties -> C/C++ -> Precompiled Headers

1. Click on "Precompiled Headers" change to "Not Using Precompiled Headers".

2. Erase the "pch.h"/"stdafx.h" field in "Precompiled Header File" for the EOF error at the end of the build for the project.

3. Then you can feel free to delete the pch./stdafx. files in your project

Add second parameter

You need to pass additional parameter to your function:

function parts($site_url, $part) { 
    $structure = 'http://' . $site_url . 'content/'; 
    echo $structure . $part . '.php'; 
}

In case of closures

If you'd rather use closures then you can import variable to the current scope (the use keyword):

$parts = function($part) use ($site_url) { 
    $structure = 'http://' . $site_url . 'content/'; 
    echo $structure . $part . '.php'; 
};

global - a bad practice

This post is frequently read, so something needs to be clarified about global. Using it is considered a bad practice (refer to this and this).

For the completeness sake here is the solution using global:

function parts($part) { 
    global $site_url;
    $structure = 'http://' . $site_url . 'content/'; 
    echo($structure . $part . '.php'); 
}

It works because you have to tell interpreter that you want to use a global variable, now it thinks it's a local variable (within your function).

The new version of SharePoint and Office (SharePoint 2010 and Office 2010) respectively are supposed to allow for this. This also includes the web based versions. I have seen Word and Excel in action do this, not sure about other client applications.

I am not sure about the specific implementation features you are asking about in terms of security though. Sorry.,=

Here is a discussion

http://blogs.msdn.com/b/sharepoint/archive/2009/10/19/sharepoint-2010.aspx

It's as easy as the following:

info_1 = "one piece of info"
info_2 = "another piece"
vars = (info_1, info_2)
# 'vars' is now a tuple with the values ("info_1", "info_2")

However, tuples in Python are immutable, so you cannot append variables to a tuple once it is created.

Agree it is probably due to a problem in resources that is preventing build of R.Java in gen. In my case a cut n paste had given a duplicate app name in string. Sort the fault, delete gen directory and clean.

In windows server 2012, even after installing asp.net you might run into this issue.

Check for "Http activation" feature. This feature is present under Web services as well.

Make sure you add the above and everything should be awesome for you !!!

Basic Authentication use base 64 Encoding for generating cryptographic string which contains the information of username and password.

Digest Access Authentication uses the hashing methodologies to generate the cryptographic result

There is no specific event for capturing browser close event.

You can only capture on unload of the current page.

By this method, it will be effected while refreshing / navigating the current page.

Even calculating of X Y postion of the mouse event doesn't give you good result.

You may also try try -Dmaven.clean.failOnError=false (from Maven FAQ)

Definitely BBEdit. I code, and BBEdit is what I use to code.

You want to make sure that appropriate files and directories are chmod-ed/permissions for those are appropriate. For all directories you want

find /opt/lampp/htdocs -type d -exec chmod 711 {} \;

And for all the images, JavaScript, CSS, HTML...well, you shouldn't execute them. So use

chmod 644 img/* js/* html/*

But for all the logic code (for instance PHP code), you should set permissions such that the user can't see that code:

chmod 600 file

You can also use the line separator character in String.format (See java.util.Formatter), which is also platform agnostic.

i.e.:

result.append(String.format("%n", ""));

If you need to add more line spaces, just use:

result.append(String.format("%n%n", ""));

You can also use StringFormat to format your entire string, with a newline(s) at the end.

result.append(String.format("%10s%n%n", "This is my string."));

Actually your command line arguments are practically like an array already. At least, you can treat the $@ variable much like an array. That said, you can convert it into an actual array like this:

myArray=( "$@" )

If you just want to type some arguments and feed them into the $@ value, use set:

$ set -- apple banana "kiwi fruit"
$ echo "$#"
3
$ echo "$@"
apple banana kiwi fruit

Understanding how to use the argument structure is particularly useful in POSIX sh, which has nothing else like an array.

I suppose you are using Windows system.

Once you open CMD you would be shown with the default location i.e. like this

C:\Users\Admin - In your case its admin as mentioned else it will be the username of your computer

Consider if you want to move to E directory then simply type E:

This will move the user to E: Directory. Now change to what ever folder you want to point to in E: Drive

Ex: If you want to move to Software directory of E folder then first type

E:

then type the location of the folder

cd E:\Software

Its working fine.

I personally prefer using Iterative over recursive function. Especially if you function has complex/heavy logic and number of iterations are large. This because with every recursive call call stack increases. It could potentially crash the stack if you operations are too large and also slow up process.

I've managed to achieve it with minimal effort (just as simple as with ASP.NET Core).

For that I use OWIN Startup.cs file and Microsoft.Owin.Security.Jwt library.

In order for the app to hit Startup.cs we need to amend Web.config:

<configuration>
  <appSettings>
    <add key="owin:AutomaticAppStartup" value="true" />
    ...

Here's how Startup.cs should look:

using MyApp.Helpers;
using Microsoft.IdentityModel.Tokens;
using Microsoft.Owin;
using Microsoft.Owin.Security;
using Microsoft.Owin.Security.Jwt;
using Owin;

[assembly: OwinStartup(typeof(MyApp.App_Start.Startup))]

namespace MyApp.App_Start
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            app.UseJwtBearerAuthentication(
                new JwtBearerAuthenticationOptions
                {
                    AuthenticationMode = AuthenticationMode.Active,
                    TokenValidationParameters = new TokenValidationParameters()
                    {
                        ValidAudience = ConfigHelper.GetAudience(),
                        ValidIssuer = ConfigHelper.GetIssuer(),
                        IssuerSigningKey = ConfigHelper.GetSymmetricSecurityKey(),
                        ValidateLifetime = true,
                        ValidateIssuerSigningKey = true
                    }
                });
        }
    }
}

Many of you guys use ASP.NET Core nowadays, so as you can see it doesn't differ a lot from what we have there.

It really got me perplexed first, I was trying to implement custom providers, etc. But I didn't expect it to be so simple. OWIN just rocks!

Just one thing to mention - after I enabled OWIN Startup NSWag library stopped working for me (e.g. some of you might want to auto-generate typescript HTTP proxies for Angular app).

The solution was also very simple - I replaced NSWag with Swashbuckle and didn't have any further issues.

Ok, now sharing ConfigHelper code:

public class ConfigHelper
{
    public static string GetIssuer()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Issuer"];
        return result;
    }

    public static string GetAudience()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["Audience"];
        return result;
    }

    public static SigningCredentials GetSigningCredentials()
    {
        var result = new SigningCredentials(GetSymmetricSecurityKey(), SecurityAlgorithms.HmacSha256);
        return result;
    }

    public static string GetSecurityKey()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["SecurityKey"];
        return result;
    }

    public static byte[] GetSymmetricSecurityKeyAsBytes()
    {
        var issuerSigningKey = GetSecurityKey();
        byte[] data = Encoding.UTF8.GetBytes(issuerSigningKey);
        return data;
    }

    public static SymmetricSecurityKey GetSymmetricSecurityKey()
    {
        byte[] data = GetSymmetricSecurityKeyAsBytes();
        var result = new SymmetricSecurityKey(data);
        return result;
    }

    public static string GetCorsOrigins()
    {
        string result = System.Configuration.ConfigurationManager.AppSettings["CorsOrigins"];
        return result;
    }
}

Another important aspect - I sent JWT Token via Authorization header, so typescript code looks for me as follows:

(the code below is generated by NSWag)

@Injectable()
export class TeamsServiceProxy {
    private http: HttpClient;
    private baseUrl: string;
    protected jsonParseReviver: ((key: string, value: any) => any) | undefined = undefined;

    constructor(@Inject(HttpClient) http: HttpClient, @Optional() @Inject(API_BASE_URL) baseUrl?: string) {
        this.http = http;
        this.baseUrl = baseUrl ? baseUrl : "https://localhost:44384";
    }

    add(input: TeamDto | null): Observable<boolean> {
        let url_ = this.baseUrl + "/api/Teams/Add";
        url_ = url_.replace(/[?&]$/, "");

        const content_ = JSON.stringify(input);

        let options_ : any = {
            body: content_,
            observe: "response",
            responseType: "blob",
            headers: new HttpHeaders({
                "Content-Type": "application/json", 
                "Accept": "application/json",
                "Authorization": "Bearer " + localStorage.getItem('token')
            })
        };

See headers part - "Authorization": "Bearer " + localStorage.getItem('token')

See example at: http://jsfiddle.net/6Rpkh/

This solved my issue

Open Windows PowerShell Command and run below query to change ExecutionPolicy

Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser

if it ask for confirm changes press 'Y' and hit enter.

Adding more to Jason's more generalized way of retrieving the POST data or GET data

from flask_restful import reqparse

def parse_arg_from_requests(arg, **kwargs):
    parse = reqparse.RequestParser()
    parse.add_argument(arg, **kwargs)
    args = parse.parse_args()
    return args[arg]

form_field_value = parse_arg_from_requests('FormFieldValue')

One small point: these are not operators. Operators are used in expressions to create new values from existing values (1+2 becomes 3, for example. The * and ** here are part of the syntax of function declarations and calls.

try to do this in the behind code

   public diagboxclass()
   {
         List<object> list = new List<object>();
         list = GetObjectList();
         Imported.ItemsSource = null;
         Imported.ItemsSource = list;
   }

Also be sure your list is effectively populated and as mentioned by Blindmeis, never use words that already are given a function in c#.

While debug I got this issue: It worked with

1. tried changing my Tomcat http port 8082 to 8083(In debug configurations on IntelliJ and in Tomcat->conf->server.xml also)
2. tried changing JMX port from 1099 to 1009.
3. tried changing debug port in Startup/Connection in debug configurations
4. killed all java processes in TaskManager->Processes.

I guess these days you would do:

import subprocess

subprocess.run(["pwd"], cwd="sub-dir")

cv2 uses numpy for manipulating images, so the proper and best way to get the size of an image is using numpy.shape. Assuming you are working with BGR images, here is an example:

>>> import numpy as np
>>> import cv2
>>> img = cv2.imread('foo.jpg')
>>> height, width, channels = img.shape
>>> print height, width, channels
  600 800 3

In case you were working with binary images, img will have two dimensions, and therefore you must change the code to: height, width = img.shape

If you want to see what is run in the database use dd(DB::getQueryLog()) to see what queries were run.

Try this

BookingDates::where('email', Input::get('email'))
    ->orWhere('name', 'like', '%' . Input::get('name') . '%')->get();

this work for me

    ncharacters.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent openncharacter = new Intent(getApplicationContext(),ncharacters.class);
            startActivity(openncharacter);
        }
    });

You need to call the Configurefunction of the XmlConfigurator

log4net.Config.XmlConfigurator.Configure();

Either call before your first loggin call or in your Global.asax like this:

protected void Application_Start(Object sender, EventArgs e) {
   log4net.Config.XmlConfigurator.Configure();
}

Pretty good documentation is provided on the MongoDB website

Install MongoDB

1. Determine which MongoDB build you need.

   There are three builds of MongoDB for Windows:

   MongoDB for Windows Server 2008 R2 edition (i.e. 2008R2) runs only on Windows Server 2008 R2, Windows 7 64-bit, and newer versions of Windows. This build takes advantage of recent enhancements to the Windows Platform and cannot operate on older versions of Windows.

   MongoDB for Windows 64-bit runs on any 64-bit version of Windows newer than Windows XP, including Windows Server 2008 R2 and Windows 7 64-bit.

   MongoDB for Windows 32-bit runs on any 32-bit version of Windows newer than Windows XP. 32-bit versions of MongoDB are only intended for older systems and for use in testing and development systems. 32-bit versions of MongoDB only support databases smaller than 2GB.

   To find which version of Windows you are running, enter the following command in the Command Prompt:

   wmic os get osarchitecture
   

2. Download MongoDB for Windows.

   Download the latest production release of MongoDB from the MongoDB downloads page. Ensure you download the correct version of MongoDB for your Windows system. The 64-bit versions of MongoDB does not work with 32-bit Windows.

3. Install the downloaded file.

   In Windows Explorer, locate the downloaded MongoDB msi file, which typically is located in the default Downloads folder. Double-click the msi file. A set of screens will appear to guide you through the installation process.

4. Move the MongoDB folder to another location (optional).

   To move the MongoDB folder, you must issue the move command as an Administrator. For example, to move the folder to C:\mongodb:

   Select Start Menu > All Programs > Accessories.

   Right-click Command Prompt and select Run as Administrator from the popup menu.

   Issue the following commands:

   cd \
   move C:\mongodb-win32-* C:\mongodb
   

   MongoDB is self-contained and does not have any other system dependencies. You can run MongoDB from any folder you choose. You may install MongoDB in any folder (e.g. D:\test\mongodb)

Run MongoDB

Warning:

Do not make mongod.exe visible on public networks without running in “Secure Mode” with the auth setting. MongoDB is designed to be run in trusted environments, and the database does not enable “Secure Mode” by default.

1. Set up the MongoDB environment.

   MongoDB requires a data directory to store all data. MongoDB’s default data directory path is \data\db. Create this folder using the following commands from a Command Prompt:

   md \data\db
   

   You can specify an alternate path for data files using the --dbpath option to mongod.exe, for example:

   C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
   

   If your path includes spaces, enclose the entire path in double quotes, for example:

   C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
   

2. Start MongoDB.

   To start MongoDB, run mongod.exe. For example, from the Command Prompt:

   C:\Program Files\MongoDB\bin\mongod.exe
   

   This starts the main MongoDB database process. The waiting for connections message in the console output indicates that the mongod.exe process is running successfully.

   Depending on the security level of your system, Windows may pop up a Security Alert dialog box about blocking “some features” of C:\Program Files\MongoDB\bin\mongod.exe from communicating on networks. All users should select Private Networks, such as my home or work network and click Allow access. For additional information on security and MongoDB, please see the Security Documentation.

3. Connect to MongoDB.

   To connect to MongoDB through the mongo.exe shell, open another Command Prompt. When connecting, specify the data directory if necessary. This step provides several example connection commands.

   If your MongoDB installation uses the default data directory, connect without specifying the data directory:

   C:\mongodb\bin\mongo.exe
   

   If you installation uses a different data directory, specify the directory when connecting, as in this example:

   C:\mongodb\bin\mongod.exe --dbpath d:\test\mongodb\data
   

   If your path includes spaces, enclose the entire path in double quotes. For example:

   C:\mongodb\bin\mongod.exe --dbpath "d:\test\mongo db data"
   

   If you want to develop applications using .NET, see the documentation of C# and MongoDB for more information.

4. Begin using MongoDB.

   To begin using MongoDB, see Getting Started with MongoDB. Also consider the Production Notes document before deploying MongoDB in a production environment.

   Later, to stop MongoDB, press Control+C in the terminal where the mongod instance is running.

Configure a Windows Service for MongoDB

Note:

There is a known issue for MongoDB 2.6.0, SERVER-13515, which prevents the use of the instructions in this section. For MongoDB 2.6.0, use Manually Create a Windows Service for MongoDB to create a Windows Service for MongoDB instead.

1. Configure directories and files.

   Create a configuration file and a directory path for MongoDB log output (logpath):

   Create a specific directory for MongoDB log files:

   md "C:\Program Files\MongoDB\log"
   

   In the Command Prompt, create a configuration file for the logpath option for MongoDB:

   echo logpath=C:\Program Files\MongoDB\log\mongo.log > "C:\Program Files\MongoDB\mongod.cfg"
   

2. Run the MongoDB service.

   Run all of the following commands in Command Prompt with “Administrative Privileges:”

   Install the MongoDB service. For --install to succeed, you must specify the logpath run-time option.

   "C:\Program Files\MongoDB\bin\mongod.exe" --config "C:\Program Files\MongoDB\mongod.cfg" --install
   

   Modify the path to the mongod.cfg file as needed.

   To use an alternate dbpath, specify the path in the configuration file (e.g. C:\Program Files\MongoDB\mongod.cfg) or on the command line with the --dbpath option.

   If the dbpath directory does not exist, mongod.exe will not start. The default value for dbpath is \data\db.

   If needed, you can install services for multiple instances of mongod.exe or mongos.exe. Install each service with a unique --serviceName and --serviceDisplayName. Use multiple instances only when sufficient system resources exist and your system design requires it.

3. Stop or remove the MongoDB service as needed.

   To stop the MongoDB service use the following command:

   net stop MongoDB
   

   To remove the MongoDB service use the following command:

   "C:\Program Files\MongoDB\bin\mongod.exe" --remove
   

Manually Create a Windows Service for MongoDB

The following procedure assumes you have installed MongoDB using the MSI installer, with the default path C:\Program Files\MongoDB 2.6 Standard.

If you have installed in an alternative directory, you will need to adjust the paths as appropriate.

1. Open an Administrator command prompt.

   Windows 7 / Vista / Server 2008 (and R2)

   Press Win + R, then type cmd, then press Ctrl + Shift + Enter.

   Windows 8

   Press Win + X, then press A.

   Execute the remaining steps from the Administrator command prompt.

2. Create directories.

   Create directories for your database and log files:

   mkdir c:\data\db
   mkdir c:\data\log
   

3. Create a configuration file.

   Create a configuration file. This file can include any of the configuration options for mongod, but must include a valid setting for logpath:

   The following creates a configuration file, specifying both the logpath and the dbpath settings in the configuration file:

   echo logpath=c:\data\log\mongod.log> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
   echo dbpath=c:\data\db>> "C:\Program Files\MongoDB 2.6 Standard\mongod.cfg"
   

4. Create the MongoDB service.

   Create the MongoDB service.

   sc.exe create MongoDB binPath= "\"C:\Program Files\MongoDB 2.6 Standard\bin\mongod.exe\" --service --config=\"C:\Program Files\MongoDB 2.6 Standard\mongod.cfg\"" DisplayName= "MongoDB 2.6 Standard" start= "auto"
   

   sc.exe requires a space between “=” and the configuration values (eg “binPath=”), and a “” to escape double quotes.

   If successfully created, the following log message will display:

   [SC] CreateService SUCCESS
   

5. Start the MongoDB service.

   net start MongoDB
   

6. Stop or remove the MongoDB service as needed.

   To stop the MongoDB service, use the following command:

   net stop MongoDB
   

   To remove the MongoDB service, first stop the service and then run the following command:

   sc.exe delete MongoDB
   

There are a set of available properties to all Maven projects.

From Introduction to the POM:

project.basedir: The directory that the current project resides in.

This means this points to where your Maven projects resides on your system. It corresponds to the location of the pom.xml file. If your POM is located inside /path/to/project/pom.xml then this property will evaluate to /path/to/project.

Some properties are also inherited from the Super POM, which is the case for project.build.directory. It is the value inside the <project><build><directory> element of the POM. You can get a description of all those values by looking at the Maven model. For project.build.directory, it is:

The directory where all files generated by the build are placed. The default value is target.

This is the directory that will hold every generated file by the build.

You have to reference System.Configuration via explorer (not only append using System.Configuration). Then you can write:

string xmlDataDirectory = 
    System.Configuration.ConfigurationManager.AppSettings.Get("xmlDataDirectory");

Tested with VS2010 (thanks to www.developpez.net). Hope this helps.

Some Bash tricks I use to set variables from commands

Sorry, there is a loong answer, but as bash is a shell, where the main goal is to run other unix commands and react to resut code and/or output, ( commands are often piped filter, etc... ).

Storing command output in variables is something basic and fundamental.

Therefore, depending on

• compatibility (posix)
• kind of output (filter(s))
• number of variable to set (split or interpret)
• execution time (monitoring)
• error trapping
• repeatability of request (see long running background process, further)
• interactivity (considering user input while reading from another input file descriptor)
• do I miss something?

First simple, old, and compatible way

myPi=`echo '4*a(1)' | bc -l`
echo $myPi 
3.14159265358979323844

Mostly compatible, second way

As nesting could become heavy, parenthesis was implemented for this

myPi=$(bc -l <<<'4*a(1)')

Nested sample:

SysStarted=$(date -d "$(ps ho lstart 1)" +%s)
echo $SysStarted 
1480656334

bash features

Reading more than one variable (with Bashisms)

df -k /
Filesystem     1K-blocks   Used Available Use% Mounted on
/dev/dm-0         999320 529020    401488  57% /

If I just want a used value:

array=($(df -k /))

you could see an array variable:

declare -p array
declare -a array='([0]="Filesystem" [1]="1K-blocks" [2]="Used" [3]="Available" [
4]="Use%" [5]="Mounted" [6]="on" [7]="/dev/dm-0" [8]="999320" [9]="529020" [10]=
"401488" [11]="57%" [12]="/")'

Then:

echo ${array[9]}
529020

But I often use this:

{ read foo ; read filesystem size using avail prct mountpoint ; } < <(df -k /)
echo $using
529020

The first read foo will just skip header line, but in only one command, you will populate 7 different variables:

declare -p avail filesystem foo mountpoint prct size using
declare -- avail="401488"
declare -- filesystem="/dev/dm-0"
declare -- foo="Filesystem     1K-blocks   Used Available Use% Mounted on"
declare -- mountpoint="/"
declare -- prct="57%"
declare -- size="999320"
declare -- using="529020"

Or

{ read -a head;varnames=(${head[@]//[K1% -]});varnames=(${head[@]//[K1% -]});
  read ${varnames[@],,} ; } < <(LANG=C df -k /)

Then:

declare -p varnames ${varnames[@],,} 
declare -a varnames=([0]="Filesystem" [1]="blocks" [2]="Used" [3]="Available" [4]="Use" [5]="Mounted" [6]="on")
declare -- filesystem="/dev/dm-0"
declare -- blocks="999320"
declare -- used="529020"
declare -- available="401488"
declare -- use="57%"
declare -- mounted="/"
declare -- on=""

Or even:

{ read foo ; read filesystem dsk[{6,2,9}] prct mountpoint ; } < <(df -k /)
declare -p mountpoint dsk
declare -- mountpoint="/"
declare -a dsk=([2]="529020" [6]="999320" [9]="401488")

(Note Used and Blocks is switched there: read ... dsk[6] dsk[2] dsk[9] ...)

... will work with associative arrays too: read foo disk[total] disk[used] ...

Dedicated fd using unnamed fifo:

There is an elegent way:

users=()
while IFS=: read -u $list user pass uid gid name home bin ;do
    ((uid>=500)) &&
        printf -v users[uid] "%11d %7d %-20s %s\n" $uid $gid $user $home
done {list}</etc/passwd

Using this way (... read -u $list; ... {list}<inputfile) leave STDIN free for other purposes, like user interaction.

Then

echo -n "${users[@]}"
       1000    1000 user         /home/user
...
      65534   65534 nobody       /nonexistent

and

echo ${!users[@]}
1000 ... 65534

echo -n "${users[1000]}"
      1000    1000 user       /home/user

This could be used with static files or even /dev/tcp/xx.xx.xx.xx/yyy with x for ip address or hostname and y for port number:

{
    read -u $list -a head          # read header in array `head`
    varnames=(${head[@]//[K1% -]}) # drop illegal chars for variable names
    while read -u $list ${varnames[@],,} ;do
        ((pct=available*100/(available+used),pct<10)) &&
            printf "WARN: FS: %-20s on %-14s %3d <10 (Total: %11u, Use: %7s)\n" \
                "${filesystem#*/mapper/}" "$mounted" $pct $blocks "$use"
     done
 } {list}< <(LANG=C df -k)

And of course with inline documents:

while IFS=\; read -u $list -a myvar ;do
    echo ${myvar[2]}
done {list}<<"eof"
foo;bar;baz
alice;bob;charlie
$cherry;$strawberry;$memberberries
eof

Sample function for populating some variables:

#!/bin/bash

declare free=0 total=0 used=0

getDiskStat() {
    local foo
    {
        read foo
        read foo total used free foo
    } < <(
        df -k ${1:-/}
    )
}

getDiskStat $1
echo $total $used $free

Nota: declare line is not required, just for readability.

About sudo cmd | grep ... | cut ...

shell=$(cat /etc/passwd | grep $USER | cut -d : -f 7)
echo $shell
/bin/bash

(Please avoid useless cat! So this is just one fork less:

shell=$(grep $USER </etc/passwd | cut -d : -f 7)

All pipes (|) implies forks. Where another process have to be run, accessing disk, libraries calls and so on.

So using sed for sample, will limit subprocess to only one fork:

shell=$(sed </etc/passwd "s/^$USER:.*://p;d")
echo $shell

And with Bashisms:

But for many actions, mostly on small files, Bash could do the job itself:

while IFS=: read -a line ; do
    [ "$line" = "$USER" ] && shell=${line[6]}
  done </etc/passwd
echo $shell
/bin/bash

or

while IFS=: read loginname encpass uid gid fullname home shell;do
    [ "$loginname" = "$USER" ] && break
  done </etc/passwd
echo $shell $loginname ...

Going further about variable splitting...

Have a look at my answer to How do I split a string on a delimiter in Bash?

Alternative: reducing forks by using backgrounded long-running tasks

In order to prevent multiple forks like

myPi=$(bc -l <<<'4*a(1)'
myRay=12
myCirc=$(bc -l <<<" 2 * $myPi * $myRay ")

or

myStarted=$(date -d "$(ps ho lstart 1)" +%s)
mySessStart=$(date -d "$(ps ho lstart $$)" +%s)

This work fine, but running many forks is heavy and slow.

And commands like date and bc could make many operations, line by line!!

See:

bc -l <<<$'3*4\n5*6'
12
30

date -f - +%s < <(ps ho lstart 1 $$)
1516030449
1517853288

So we could use a long running background process to make many jobs, without having to initiate a new fork for each request.

Under bash, there is a built-in function: coproc:

coproc bc -l
echo 4*3 >&${COPROC[1]}
read -u $COPROC answer
echo $answer
12

echo >&${COPROC[1]} 'pi=4*a(1)'
ray=42.0
printf >&${COPROC[1]} '2*pi*%s\n' $ray
read -u $COPROC answer
echo $answer
263.89378290154263202896

printf >&${COPROC[1]} 'pi*%s^2\n' $ray
read -u $COPROC answer
echo $answer
5541.76944093239527260816

As bc is ready, running in background and I/O are ready too, there is no delay, nothing to load, open, close, before or after operation. Only the operation himself! This become a lot quicker than having to fork to bc for each operation!

Border effect: While bc stay running, they will hold all registers, so some variables or functions could be defined at initialisation step, as first write to ${COPROC[1]}, just after starting the task (via coproc).

Into a function newConnector

You may found my newConnector function on GitHub.Com or on my own site (Note on GitHub: there are two files on my site. Function and demo are bundled into one uniq file which could be sourced for use or just run for demo.)

Sample:

source shell_connector.sh

tty
/dev/pts/20

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30745 pts/20   R+     0:00  \_ ps --tty pts/20 fw

newConnector /usr/bin/bc "-l" '3*4' 12

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  30952 pts/20   R+     0:00  \_ ps --tty pts/20 fw

declare -p PI
bash: declare: PI: not found

myBc '4*a(1)' PI
declare -p PI
declare -- PI="3.14159265358979323844"

The function myBc lets you use the background task with simple syntax, and for date:

newConnector /bin/date '-f - +%s' @0 0
myDate '2000-01-01'
  946681200
myDate "$(ps ho lstart 1)" boottime
myDate now now ; read utm idl </proc/uptime
myBc "$now-$boottime" uptime
printf "%s\n" ${utm%%.*} $uptime
  42134906
  42134906

ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
  29019 pts/20   Ss     0:00 bash
  30944 pts/20   S      0:00  \_ /usr/bin/bc -l
  32615 pts/20   S      0:00  \_ /bin/date -f - +%s
   3162 pts/20   R+     0:00  \_ ps --tty pts/20 fw

From there, if you want to end one of background processes, you just have to close its fd:

eval "exec $DATEOUT>&-"
eval "exec $DATEIN>&-"
ps --tty pts/20 fw
    PID TTY      STAT   TIME COMMAND
   4936 pts/20   Ss     0:00 bash
   5256 pts/20   S      0:00  \_ /usr/bin/bc -l
   6358 pts/20   R+     0:00  \_ ps --tty pts/20 fw

which is not needed, because all fd close when the main process finishes.

I had the following problem(s) with the existing answers to this question (and variations of this question on other stackoverflow threads):

• None of the loaded code was debuggable
• Many of the solutions required callbacks to know when loading was finished instead of truly blocking, meaning I would get execution errors from immediately calling loaded (ie loading) code.

Or, slightly more accurately:

• None of the loaded code was debuggable (except from the HTML script tag block, if and only if the solution added a script elements to the dom, and never ever as individual viewable scripts.) => Given how many scripts I have to load (and debug), this was unacceptable.
• Solutions using 'onreadystatechange' or 'onload' events failed to block, which was a big problem since the code originally loaded dynamic scripts synchronously using 'require([filename, 'dojo/domReady']);' and I was stripping out dojo.

My final solution, which loads the script before returning, AND has all scripts properly accessible in the debugger (for Chrome at least) is as follows:

WARNING: The following code should PROBABLY be used only in 'development' mode. (For 'release' mode I recommend prepackaging and minification WITHOUT dynamic script loading, or at least without eval).

//Code User TODO: you must create and set your own 'noEval' variable

require = function require(inFileName)
{
    var aRequest
        ,aScript
        ,aScriptSource
        ;

    //setup the full relative filename
    inFileName = 
        window.location.protocol + '//'
        + window.location.host + '/'
        + inFileName;

    //synchronously get the code
    aRequest = new XMLHttpRequest();
    aRequest.open('GET', inFileName, false);
    aRequest.send();

    //set the returned script text while adding special comment to auto include in debugger source listing:
    aScriptSource = aRequest.responseText + '\n////# sourceURL=' + inFileName + '\n';

    if(noEval)//<== **TODO: Provide + set condition variable yourself!!!!**
    {
        //create a dom element to hold the code
        aScript = document.createElement('script');
        aScript.type = 'text/javascript';

        //set the script tag text, including the debugger id at the end!!
        aScript.text = aScriptSource;

        //append the code to the dom
        document.getElementsByTagName('body')[0].appendChild(aScript);
    }
    else
    {
        eval(aScriptSource);
    }
};

@Robino was suggesting to add some tests which make sense, so here is a simple benchmark between 3 possible ways (maybe the most used ones) to convert an iterator to a list:

1. by type constructor

list(my_iterator)

1. by unpacking

[*my_iterator]

3. using list comprehension

[e for e in my_iterator]

I have been using simple_bechmark library

from simple_benchmark import BenchmarkBuilder
from heapq import nsmallest

b = BenchmarkBuilder()

@b.add_function()
def convert_by_type_constructor(size):
    list(iter(range(size)))

@b.add_function()
def convert_by_list_comprehension(size):
    [e for e in iter(range(size))]

@b.add_function()
def convert_by_unpacking(size):
    [*iter(range(size))]


@b.add_arguments('Convert an iterator to a list')
def argument_provider():
    for exp in range(2, 22):
        size = 2**exp
        yield size, size

r = b.run()
r.plot()

As you can see there is very hard to make a difference between conversion by the constructor and conversion by unpacking, conversion by list comprehension is the “slowest” approach.

I have been testing also across different Python versions (3.6, 3.7, 3.8, 3.9) by using the following simple script:

import argparse
import timeit

parser = argparse.ArgumentParser(
    description='Test convert iterator to list')
parser.add_argument(
    '--size', help='The number of elements from iterator')

args = parser.parse_args()

size = int(args.size)
repeat_number = 10000

# do not wait too much if the size is too big
if size > 10000:
    repeat_number = 100


def test_convert_by_type_constructor():
    list(iter(range(size)))


def test_convert_by_list_comprehension():
    [e for e in iter(range(size))]


def test_convert_by_unpacking():
    [*iter(range(size))]


def get_avg_time_in_ms(func):
    avg_time = timeit.timeit(func, number=repeat_number) * 1000 / repeat_number
    return round(avg_time, 6)


funcs = [test_convert_by_type_constructor,
         test_convert_by_unpacking, test_convert_by_list_comprehension]

print(*map(get_avg_time_in_ms, funcs))

The script will be executed via a subprocess from a Jupyter Notebook (or a script), the size parameter will be passed through command-line arguments and the script results will be taken from standard output.

from subprocess import PIPE, run

import pandas

simple_data = {'constructor': [], 'unpacking': [], 'comprehension': [],
        'size': [], 'python version': []}


size_test = 100, 1000, 10_000, 100_000, 1_000_000
for version in ['3.6', '3.7', '3.8', '3.9']:
    print('test for python', version)
    for size in size_test:
        command = [f'python{version}', 'perf_test_convert_iterator.py', f'--size={size}']
        result = run(command, stdout=PIPE, stderr=PIPE, universal_newlines=True)
        constructor, unpacking,  comprehension = result.stdout.split()
        
        simple_data['constructor'].append(float(constructor))
        simple_data['unpacking'].append(float(unpacking))
        simple_data['comprehension'].append(float(comprehension))
        simple_data['python version'].append(version)
        simple_data['size'].append(size)

df_ = pandas.DataFrame(simple_data)
df_

You can get my full notebook from here.

In most of the cases, in my tests, unpacking shows to be faster, but the difference is so small that the results may change from a run to the other. Again, the comprehension approach is the slowest, in fact, the other 2 methods are up to ~ 60% faster.

If you think about it, a body XRay scan (at the medical center) too needs this kind of measurement for estimating size of tumors. So they place a 1 Dollar Coin on the body, to do a comparative measurement.

Even newspaper is printed with some marks on the corners.

You need a reference to measure. May be you can get your person to wear a cap which has a few bright green circles. Once you recognize the size of the circle you can comparatively measure the remaining.

Or you can create a transparent 1 inch circle which will superimpose on the face, move the camera toward/away the face, aim your superimposed circle on that bright green circle on the cap. Then on your photo will be as per scale.

Make your audioSounds and minTime variables as static variables, as you are using them in a static method (playSound).

Marking a method as static prevents the usage of non-static (instance) members in that method.

If you really mean pure working Directory, this should suit for you.

Solution A:

Dim ParentPath As String: ParentPath = "\"
Dim ThisWorkbookPath As String
Dim ThisWorkbookPathParts, Part As Variant
Dim Count, Parts As Long

ThisWorkbookPath = ThisWorkbook.Path
ThisWorkbookPathParts = Split(ThisWorkbookPath, _
                        Application.PathSeparator)

Parts = UBound(ThisWorkbookPathParts)
Count = 0
For Each Part In ThisWorkbookPathParts
    If Count > 0 Then
        ParentPath = ParentPath & Part & "\"
    End If
    Count = Count + 1
    If Count = Parts Then Exit For
Next

MsgBox "File-Drive = " & ThisWorkbookPathParts _
       (LBound(ThisWorkbookPathParts))
MsgBox "Parent-Path = " & ParentPath

But if don't, this should be enough.

Solution B:

Dim ThisWorkbookPath As String

ThisWorkbookPath = ThisWorkbook.Path
MsgBox "Working-Directory = " & ThisWorkbookPath

The Logbook library is specifically made for logging HTTP requests and responses. It supports Spring Boot using a special starter library.

To enable logging in Spring Boot all you need to do is adding the library to your project's dependencies. For example assuming you are using Maven:

<dependency>
    <groupId>org.zalando</groupId>
    <artifactId>logbook-spring-boot-starter</artifactId>
    <version>1.5.0</version>
</dependency>

By default the logging output looks like this:

{
  "origin" : "local",
  "correlation" : "52e19498-890c-4f75-a06c-06ddcf20836e",
  "status" : 200,
  "headers" : {
    "X-Application-Context" : [
      "application:8088"
    ],
    "Content-Type" : [
      "application/json;charset=UTF-8"
    ],
    "Transfer-Encoding" : [
      "chunked"
    ],
    "Date" : [
      "Sun, 24 Dec 2017 13:10:45 GMT"
    ]
  },
  "body" : {
    "thekey" : "some_example"
  },
  "duration" : 105,
  "protocol" : "HTTP/1.1",
  "type" : "response"
}

It does however not output the class name that is handling the request. The library does have some interfaces for writing custom loggers.

Notes

In the meantime the library has significantly evolved, current version is 2.4.1, see https://github.com/zalando/logbook/releases. E.g. the default ouput format has changed, and can be configured, filtered, etc.

Do NOT forget to set the log level to TRACE, else you won't see anything:

logging:
  level:
    org.zalando.logbook: TRACE

Can this be done with bootstrap 3's carousel? I'm hoping I won't have to go hunting for yet another jQuery plugin

As of 2013-12-08 the answer is no. The effect you are looking for is not possible using Bootstrap 3's generic carousel plugin. However, here's a simple jQuery plugin that seems to do exactly what you want http://sorgalla.com/jcarousel/

First approach with Windows Service is not easy..

A long time ago, I wrote a C# service.

This is the logic of the Service class (tested, works fine):

namespace MyServiceApp
{
    public class MyService : ServiceBase
    {
        private System.Timers.Timer timer;

        protected override void OnStart(string[] args)
        {
            this.timer = new System.Timers.Timer(30000D);  // 30000 milliseconds = 30 seconds
            this.timer.AutoReset = true;
            this.timer.Elapsed += new System.Timers.ElapsedEventHandler(this.timer_Elapsed);
            this.timer.Start();
        }

        protected override void OnStop()
        {
            this.timer.Stop();
            this.timer = null;
        }

        private void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
        {
            MyServiceApp.ServiceWork.Main(); // my separate static method for do work
        }

        public MyService()
        {
            this.ServiceName = "MyService";
        }

        // service entry point
        static void Main()
        {
            System.ServiceProcess.ServiceBase.Run(new MyService());
        }
    }
}

I recommend you write your real service work in a separate static method (why not, in a console application...just add reference to it), to simplify debugging and clean service code.

Make sure the interval is enough, and write in log ONLY in OnStart and OnStop overrides.

Hope this helps!

Visual Studio reads NuGet.Config files from the solution root. Try moving it there instead of placing it in the same folder as the project.

You can also place the file at %appdata%\NuGet\NuGet.Config and it will be used everywhere.

https://docs.microsoft.com/en-us/nuget/schema/nuget-config-file

You can pass the parameter(s) as a property of the function object, not as a parameter:

var f = this.someFunction;  //use 'this' if called from class
f.parameter1 = obj;
f.parameter2 = this;
f.parameter3 = whatever;
setInterval(f, 1000);

Then in your function someFunction, you will have access to the parameters. This is particularly useful inside classes where the scope goes to the global space automatically and you lose references to the class that called setInterval to begin with. With this approach, "parameter2" in "someFunction", in the example above, will have the right scope.

Automated Tasks: Cron

Cron is a time-based scheduling service in Linux / Unix-like computer operating systems. Cron job are used to schedule commands to be executed periodically. You can setup commands or scripts, which will repeatedly run at a set time. Cron is one of the most useful tool in Linux or UNIX like operating systems. The cron service (daemon) runs in the background and constantly checks the /etc/crontab file, /etc/cron./* directories. It also checks the /var/spool/cron/ directory.

Configuring Cron Tasks

In the following example, the crontab command shown below will activate the cron tasks automatically every ten minutes:

*/10 * * * * /usr/bin/php /opt/test.php

In the above sample, the */10 * * * * represents when the task should happen. The first figure represents minutes – in this case, on every "ten" minute. The other figures represent, respectively, hour, day, month and day of the week.

* is a wildcard, meaning "every time".

Start with finding out your PHP binary by typing in command line:

whereis php

The output should be something like:

php: /usr/bin/php /etc/php.ini /etc/php.d /usr/lib64/php /usr/include/php /usr/share/php /usr/share/man/man1/php.1.gz

Specify correctly the full path in your command.

Type the following command to enter cronjob:

crontab -e

To see what you got in crontab.

Just ran into this... I have a common library shared among multiple transpiled products. I was using symlinks with brunch to handle sharing things between the projects. When moving to webpack, this stopped working.

What did get things working was using webpack configuration to turn off symlink resolving.

i.e. adding this in webpack.config.js:

module.exports = {
  //...
  resolve: {
    symlinks: false
  }
};

as documented here:

https://webpack.js.org/configuration/resolve/#resolvesymlinks

You could try this:

SELECT * 
FROM table 
ORDER BY (c_counts+f_counts) 
LIMIT 20

This is an old, answered, question, but @Alexandre asked "Why would anyone want to do this?", and I thought that I might provide an example usage that I am considering this afternoon.

Legacy code. Uses naked pointers Obj*obj with a delete obj at the end.

Unfortunately I need sometimes, not often, to keep the object alive longer.

I am considering making it a reference counted smart pointer. But there would be lots of code to change, if I was to use ref_cnt_ptr<Obj> everywhere. And if you mix naked Obj* and ref_cnt_ptr, you can get the object implicitly deleted when the last ref_cnt_ptr goes away, even though there are Obj* still alive.

So I am thinking about creating an explicit_delete_ref_cnt_ptr. I.e. a reference counted pointer where the delete is only done in an explicit delete routine. Using it in the one place where the existing code knows the lifetime of the object, as well as in my new code that keeps the object alive longer.

Incrementing and decrementing the reference count as explicit_delete_ref_cnt_ptr get manipulated.

But NOT freeing when the reference count is seen to be zero in the explicit_delete_ref_cnt_ptr destructor.

Only freeing when the reference count is seen to be zero in an explicit delete-like operation. E.g. in something like:

template<typename T> class explicit_delete_ref_cnt_ptr { 
 private: 
   T* ptr;
   int rc;
   ...
 public: 
   void delete_if_rc0() {
      if( this->ptr ) {
        this->rc--;
        if( this->rc == 0 ) {
           delete this->ptr;
        }
        this->ptr = 0;
      }
    }
 };

OK, something like that. It's a bit unusual to have a reference counted pointer type not automatically delete the object pointed to in the rc'ed ptr destructor. But it seems like this might make mixing naked pointers and rc'ed pointers a bit safer.

But so far no need for delete this.

But then it occurred to me: if the object pointed to, the pointee, knows that it is being reference counted, e.g. if the count is inside the object (or in some other table), then the routine delete_if_rc0 could be a method of the pointee object, not the (smart) pointer.

class Pointee { 
 private: 
   int rc;
   ...
 public: 
   void delete_if_rc0() {
        this->rc--;
        if( this->rc == 0 ) {
           delete this;
        }
      }
    }
 };

Actually, it doesn't need to be a member method at all, but could be a free function:

map<void*,int> keepalive_map;
template<typename T>
void delete_if_rc0(T*ptr) {
        void* tptr = (void*)ptr;
        if( keepalive_map[tptr] == 1 ) {
           delete ptr;
        }
};

(BTW, I know the code is not quite right - it becomes less readable if I add all the details, so I am leaving it like this.)

I didn't understand how the accepted answer answers the actual question of how to run any commands on the server after sshpass is given from within the bash script file. For that reason, I'm providing an answer.

After your provided script commands, execute additional commands like below:

sshpass -p 'password' ssh user@host "ls; whois google.com;" #or whichever commands you would like to use, for multiple commands provide a semicolon ; after the command

In your script:

#! /bin/bash

sshpass -p 'password' ssh user@host "ls; whois google.com;"

Upgrading to Snow Leopard won't solve the your primary problem of keeping PHP up to date. Apple doesn't always keep the third party software that it bundles up to date with OS updates. And relying on Apple to get you the bug fix / security update you need is asking for trouble.

Additionally, I would recommend installing through MacPorts (and doing the config necessary to use it instead of Apple's PHP) rather than try to upgrade the Apple supplied PHP in place. Anything you do to /usr/bin risks being overwritten by some future Apple update.

I'd recommend looking at consistent gets/logical reads as a better proxy for 'work' than run time. The run time can be skewed by what else is happening on the database server, how much stuff is in the cache etc.

But if you REALLY want SQL executing time, the V$SQL view has both CPU_TIME and ELAPSED_TIME.

Before messing with Nginx config, try to disable ChromePHP first.

1 - Open app/config/config_dev.yml

2 - Comment these lines:

chromephp:
    type:   chromephp
    level:  info

ChromePHP pack the debug info json-encoded in the X-ChromePhp-Data header, which is too big for the default config of nginx with fastcgi.

make sure you phone and mac machine both connected to the same wifi and you good to go your http://<machine-name>.local

On a semi-related note, if you want to start a process that has more privileges than your current process (say, launching an admin app, which requires Administrator rights, from the main app running as a normal user), you can't do so using CreateProcess() on Vista since it won't trigger the UAC dialog (assuming it is enabled). The UAC dialog is triggered when using ShellExecute(), though.

Summary:

The new keyword is used in javascript to create a object from a constructor function. The new keyword has to be placed before the constructor function call and will do the following things:

1. Creates a new object
2. Sets the prototype of this object to the constructor function's prototype property
3. Binds the this keyword to the newly created object and executes the constructor function
4. Returns the newly created object

Example:

function Dog (age) {
  this.age = age;
}

const doggie = new Dog(12);

console.log(doggie);
console.log(Object.getPrototypeOf(doggie) === Dog.prototype) // true

What exactly happens:

1. const doggie says: We need memory for declaring a variable.
2. The assigment operator = says: We are going to initialize this variable with the expression after the =
3. The expression is new Dog(12). The JS engine sees the new keyword, creates a new object and sets the prototype to Dog.prototype
4. The constructor function is executed with the this value set to the new object. In this step is where the age is assigned to the new created doggie object.
5. The newly created object is returned and assigned to the variable doggie.

Do adb remount. And then try adb shell

1. Make your data immutable if it is possible ( final variables)
2. If you can't avoid mutation of shared data across multiple threads, use high level programming constructs [e.g. granular Lock API ]

A Lock provides exclusive access to a shared resource: only one thread at a time can acquire the lock and all access to the shared resource requires that the lock be acquired first.

Sample code to use ReentrantLock which implements Lock interface

 class X {
   private final ReentrantLock lock = new ReentrantLock();
   // ...

   public void m() {
     lock.lock();  // block until condition holds
     try {
       // ... method body
     } finally {
       lock.unlock()
     }
   }
 }

Advantages of Lock over Synchronized(this)

1. The use of synchronized methods or statements forces all lock acquisition and release to occur in a block-structured way.

2. Lock implementations provide additional functionality over the use of synchronized methods and statements by providing

   1. A non-blocking attempt to acquire a lock (tryLock())
   2. An attempt to acquire the lock that can be interrupted (lockInterruptibly())
   3. An attempt to acquire the lock that can timeout (tryLock(long, TimeUnit)).

3. A Lock class can also provide behavior and semantics that is quite different from that of the implicit monitor lock, such as

   1. guaranteed ordering
   2. non-re entrant usage
   3. Deadlock detection

Have a look at this SE question regarding various type of Locks:

Synchronization vs Lock

You can achieve thread safety by using advanced concurrency API instead of Synchronied blocks. This documentation page provides good programming constructs to achieve thread safety.

Lock Objects support locking idioms that simplify many concurrent applications.

Executors define a high-level API for launching and managing threads. Executor implementations provided by java.util.concurrent provide thread pool management suitable for large-scale applications.

Concurrent Collections make it easier to manage large collections of data, and can greatly reduce the need for synchronization.

Atomic Variables have features that minimize synchronization and help avoid memory consistency errors.

ThreadLocalRandom (in JDK 7) provides efficient generation of pseudorandom numbers from multiple threads.

Refer to java.util.concurrent and java.util.concurrent.atomic packages too for other programming constructs.

Since the API you're calling is async, the Parallel.ForEach version doesn't make much sense. You shouldnt use .Wait in the WaitAll version since that would lose the parallelism Another alternative if the caller is async is using Task.WhenAll after doing Select and ToArray to generate the array of tasks. A second alternative is using Rx 2.0

You need the xml.etree.ElementTree.fromstring(text)

from xml.etree.ElementTree import XML, fromstring
myxml = fromstring(text)

This can also be done in the GUI:

1. Under the table "Person", right click Indexes
2. Click/hover New Index
3. Click Non-Clustered Index...

4. A default Index name will be given but you may want to change it.
5. Check Unique checkbox
6. Click Add... button

7. Check the columns you want included

8. Click OK in each window.

For those who came here looking for a way to download a blob url video / audio, this answer worked for me. In short, you would need to find an *.m3u8 file on the desired web page through Chrome -> Network tab and paste it into a VLC player.

Another guide shows you how to save a stream with the VLC Player.

Like this:

$(this).data('id');
$(this).data('option');

Working example: http://jsfiddle.net/zwHUc/

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

Does is need to be an array? If you use an ArrayList or one of the other objects available in C#, you won't have this limitation to content with. Hashtable, IDictionnary, IList, etc.. all allow a dynamic number of elements.

You can simply change the name of the file by changing the name of the file in the second parameter of move_uploaded_file.

Instead of

move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $_FILES["file"]["name"]);

Use

$temp = explode(".", $_FILES["file"]["name"]);
$newfilename = round(microtime(true)) . '.' . end($temp);
move_uploaded_file($_FILES["file"]["tmp_name"], "../img/imageDirectory/" . $newfilename);

Changed to reflect your question, will product a random number based on the current time and append the extension from the originally uploaded file.

As an alternative way you can use DriverManagerDataSource such as:

public DataSource getDataSource(DBInfo db) {

    DriverManagerDataSource dataSource = new DriverManagerDataSource();

    dataSource.setUsername(db.getUsername());
    dataSource.setPassword(db.getPassword());
    dataSource.setUrl(db.getUrl());
    dataSource.setDriverClassName(db.getDriverClassName());

    return dataSource;
}

However be careful about using it, because:

NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call. reference

create table the_easy_way(
  capture_ts DATETIME DEFAULT CURRENT_TIMESTAMP,
  capture_dt DATE AS (DATE(capture_ts))
)

For Android 2.3 this can be done with some very heavy hacking:

The root cause for the issues with Android 2.3 is that in LayoutInflater the mConstructorArgs[0] = mContext is only set during running calls to

http://grepcode.com/file/repository.grepcode.com/java/ext/com.google.android/android/2.3.3_r1/android/view/LayoutInflater.java/#352

protected void setMenuBackground(){

    getLayoutInflater().setFactory( new Factory() {

        @Override
        public View onCreateView (final String name, final Context context, final AttributeSet attrs ) {

            if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {

                try { // Ask our inflater to create the view
                    final LayoutInflater f = getLayoutInflater();
                    final View[] view = new View[1]:
                    try {
                        view[0] = f.createView( name, null, attrs );
                    } catch (InflateException e) {
                        hackAndroid23(name, attrs, f, view);
                    }
                    // Kind of apply our own background
                    new Handler().post( new Runnable() {
                        public void run () {
                            view.setBackgroundResource( R.drawable.gray_gradient_background);
                        }
                    } );
                    return view;
                }
                catch ( InflateException e ) {
                }
                catch ( ClassNotFoundException e ) {
                }
            }
            return null;
        }
    });
}

static void hackAndroid23(final String name,
    final android.util.AttributeSet attrs, final LayoutInflater f,
    final TextView[] view) {
    // mConstructorArgs[0] is only non-null during a running call to inflate()
    // so we make a call to inflate() and inside that call our dully XmlPullParser get's called
    // and inside that it will work to call "f.createView( name, null, attrs );"!
    try {
        f.inflate(new XmlPullParser() {
            @Override
            public int next() throws XmlPullParserException, IOException {
                try {
                    view[0] = (TextView) f.createView( name, null, attrs );
                } catch (InflateException e) {
                } catch (ClassNotFoundException e) {
                }
                throw new XmlPullParserException("exit");
            }   
        }, null, false);
    } catch (InflateException e1) {
        // "exit" ignored
    }
}

I tested it to work on Android 2.3 and to still work on earlier versions. If anything breaks again in later Android versions you'll simply see the default menu-style instead

Krasimir Tsonev has a great solution that overcome all problems. His method doesn't need using eval, so no performance nor security problems exist. It allows you to set innerHTML string contains html with js and translate it immediately to an DOM element while also executes the js parts exist along the code. short ,simple, and works exactly as you want.

Enjoy his solution:

http://krasimirtsonev.com/blog/article/Convert-HTML-string-to-DOM-element

Important notes:

1. You need to wrap the target element with div tag
2. You need to wrap the src string with div tag.
3. If you write the src string directly and it includes js parts, please take attention to write the closing script tags correctly (with \ before /) as this is a string.

You need CSS to achieve this, e.g.:

#container_2 {
    -webkit-transform: rotate(90deg);
    -moz-transform: rotate(90deg);
    -o-transform: rotate(90deg);
    -ms-transform: rotate(90deg);
    transform: rotate(90deg);
}

Demo:

#container_2 {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid red;_x000D_
  -webkit-transform: rotate(45deg);_x000D_
  -moz-transform: rotate(45deg);_x000D_
  -o-transform: rotate(45deg);_x000D_
  -ms-transform: rotate(45deg);_x000D_
  transform: rotate(45deg);_x000D_
}

<div id="container_2"></div>

(There's 45 degrees rotation in the demo, so you can see the effect)

Note: The -o- and -moz- prefixes are no longer relevant and probably not required. IE9 requires -ms- and Safari and the Android browser require -webkit-

Update 2018: Vendor prefixes are not needed anymore. Only transform is sufficient. (thanks @rinogo)

I need this quite often to deal with stacks, and i always find myself baffled that there's no native function that does it without manipulating the array or its internal pointer in some form.

So i usually carry around a util function that's also safe to use on associative arrays.

function array_last($array) {
    if (count($array) < 1)
        return null;

    $keys = array_keys($array);
    return $array[$keys[sizeof($keys) - 1]];
}

This works for me, hope this will work for you too. It will give you a Record set Root to Child for any Specific Menu. Change the Field name as per your requirements.

SET @id:= '22';

SELECT Menu_Name, (@id:=Sub_Menu_ID ) as Sub_Menu_ID, Menu_ID 
FROM 
    ( SELECT Menu_ID, Menu_Name, Sub_Menu_ID 
      FROM menu 
      ORDER BY Sub_Menu_ID DESC
    ) AS aux_table 
    WHERE Menu_ID = @id
     ORDER BY Sub_Menu_ID;

If you don't have another time interval bigger than days:

int days = (int) (milliseconds / (1000*60*60*24));

If you have weeks too:

int days = (int) ((milliseconds / (1000*60*60*24)) % 7);
int weeks = (int) (milliseconds / (1000*60*60*24*7));

It's probably best to avoid using months and years if possible, as they don't have a well-defined fixed length. Strictly speaking neither do days: daylight saving means that days can have a length that is not 24 hours.

You can use the unset keyword to reset a property.

div.rounded div div div {
    background-image: unset; /* reset background */
    padding: unset; /* reset padding */
}

There are two ways. In case of doubt, you can always just try it. If it does not work, you can add extra braces to make sure, like that:

if not ((u0 <= u) and (u < u0+step)):

If you have a char array allocated you can simply put a '\0' wherever you want. Then point a new char * pointer to the location just after the newly inserted '\0'.

This will destroy your original string though depending on where you put the '\0'

(parseFloat('2.3') + parseFloat('2.4')).toFixed(1);

its going to give you solution i suppose

You can achieve it via Random class object random.nextInt(max), which is in dart:math library. The nextInt() method requires a max limit. The random number starts from 0 and the max limit itself is exclusive.

import 'dart:math';
Random random = new Random();
int randomNumber = random.nextInt(100); // from 0 upto 99 included

If you want to add the min limit, add the min limit to the result

int randomNumber = random.nextInt(90) + 10; // from 10 upto 99 included

Generally

• Formatting numbers in JavaScript
• Formatting numbers for currency display and more.

In jQuery

• autoNumeric (a decent number formatter & input helper with locale support for jQuery 1.5+)
• jQuery Format (a clientSide implementation of Java's SimpleDateFormat and NumberFormat)
• jquery-numberformatter (number formatter with locale support)

ANSWER: <embed src="https://YOURDOMAIN.com/PAGE.HTM" style="width:100%; height: 50vw;">

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

That's not possible using the built-in Array.prototype.map. However, you could use a simple for-loop instead, if you do not intend to map any values:

var hasValueLessThanTen = false;
for (var i = 0; i < myArray.length; i++) {
  if (myArray[i] < 10) {
    hasValueLessThanTen = true;
    break;
  }
}

Or, as suggested by @RobW, use Array.prototype.some to test if there exists at least one element that is less than 10. It will stop looping when some element that matches your function is found:

var hasValueLessThanTen = myArray.some(function (val) { 
  return val < 10;
});

since the selected answer didn't actually work .. and if you're not using jquery here is a simple throttle function with an example of how to use it with window resizing

    function throttle(end,delta) {

    var base = this;

    base.wait = false;
    base.delta = 200;
    base.end = end;

    base.trigger = function(context) {

        //only allow if we aren't waiting for another event
        if ( !base.wait ) {

            //signal we already have a resize event
            base.wait = true;

            //if we are trying to resize and we 
            setTimeout(function() {

                //call the end function
                if(base.end) base.end.call(context);

                //reset the resize trigger
                base.wait = false;
            }, base.delta);
        }
    }
};

var windowResize = new throttle(function() {console.log('throttle resize');},200);

window.onresize = function(event) {
    windowResize.trigger();
}

You should use the following code :

Class2 cls2 = new Class2();
cls2.UpdateEmployee();

In case you don't want to create a new instance to call the method, you can decalre the method as static and then you can just call Class2.UpdateEmployee().

This is how its done,in Android Studio for windows

Done

$(window).height();

To set anything in the middle you can use CSS.

<style>
#divCentre 
{ 
    position: absolute;
    left: 50%;
    top: 50%;
    width: 300px;
    height: 400px;
    margin-left: -150px;
    margin-top: -200px;
}
</style>
<div id="divCentre">I am at the centre</div>

You might also consider using the open source SpringSandwich library which lets you directly annotate in your Spring Boot controllers which interceptors to apply, much in the same way you annotate your url routes.

That way, no typo-prone Strings floating around -- SpringSandwich's method and class annotations easily survive refactoring and make it clear what's being applied where. (Disclosure: I'm the author).

For most of my projects I use following pattern:

1. Create settings_base.py where I store settings that are common for all environments
2. Whenever I need to use new environment with specific requirements I create new settings file (eg. settings_local.py) which inherits contents of settings_base.py and overrides/adds proper settings variables (from settings_base import *)

(To run manage.py with custom settings file you simply use --settings command option: manage.py <command> --settings=settings_you_wish_to_use.py)

Unrelated to the question (Mehrdad's answer should get you going), and I hope this isn't taken as nitpicky: classes don't inherit interfaces, they implement them.

.NET does not support multiple-inheritance, so keeping the terms straight can help in communication. A class can inherit from one superclass and can implement as many interfaces as it wishes.

In response to Eric's comment... I had a discussion with another developer about whether or not interfaces "inherit", "implement", "require", or "bring along" interfaces with a declaration like:

public interface ITwo : IOne

The technical answer is that ITwo does inherit IOne for a few reasons:

• Interfaces never have an implementation, so arguing that ITwo implements IOne is flat wrong
• ITwo inherits IOne methods, if MethodOne() exists on IOne then it is also accesible from ITwo. i.e: ((ITwo)someObject).MethodOne()) is valid, even though ITwo does not explicitly contain a definition for MethodOne()
• ...because the runtime says so! typeof(IOne).IsAssignableFrom(typeof(ITwo)) returns true

We finally agreed that interfaces support true/full inheritance. The missing inheritance features (such as overrides, abstract/virtual accessors, etc) are missing from interfaces, not from interface inheritance. It still doesn't make the concept simple or clear, but it helps understand what's really going on under the hood in Eric's world :-)

Keep in mind that @"%d" will only work on 32 bit. Once you start using NSInteger for compatibility if you ever compile for a 64 bit platform, you should use @"%ld" as your format specifier.

You could use a shortcut library to handle the browser specific stuff.

shortcut.add("Ctrl+S",function() {
    alert("Hi there!");
});

override func tableView(tableView: UITableView, editActionsForRowAtIndexPath indexPath: NSIndexPath) -> [UITableViewRowAction]? {
    let delete = UITableViewRowAction(style: .Destructive, title: "Delete") { (action, indexPath) in
        // delete item at indexPath
    }

    let share = UITableViewRowAction(style: .Normal, title: "Disable") { (action, indexPath) in
    // share item at indexPath
    }

    share.backgroundColor = UIColor.blueColor()

    return [delete, share]
}

The above code shows how to create to custom buttons when your swipe on the row.

If, like me, none of the above quite works, it might be worth also specifically trying a lower TLS version alone. I had tried both of the following, but didn't seem to solve my problem:

[Net.ServicePointManager]::SecurityProtocol = "tls12, tls11, tls"
[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 -bor [Net.SecurityProtocolType]::Tls11 -bor [Net.SecurityProtocolType]::Tls

In the end, it was only when I targetted TLS 1.0 (specifically remove 1.1 and 1.2 in the code) that it worked:

[Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls

The local server (that this was being attempted on) is fine with TLS 1.2, although the remote server (which was previously "confirmed" as fine for TLS 1.2 by a 3rd party) seems not to be.

Hope this helps someone.

Sqlite helper class helps us to manage database creation and version management. SQLiteOpenHelper takes care of all database management activities. To use it,
1.Override onCreate(), onUpgrade() methods of SQLiteOpenHelper. Optionally override onOpen() method.
2.Use this subclass to create either a readable or writable database and use the SQLiteDatabase's four API methods insert(), execSQL(), update(), delete() to create, read, update and delete rows of your table.

Example to create a MyEmployees table and to select and insert records:

public class MyDatabaseHelper extends SQLiteOpenHelper {

    private static final String DATABASE_NAME = "DBName";

    private static final int DATABASE_VERSION = 2;

    // Database creation sql statement
    private static final String DATABASE_CREATE = "create table MyEmployees
                                 ( _id integer primary key,name text not null);";

    public MyDatabaseHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    // Method is called during creation of the database
    @Override
    public void onCreate(SQLiteDatabase database) {
        database.execSQL(DATABASE_CREATE);
    }

    // Method is called during an upgrade of the database,
    @Override
    public void onUpgrade(SQLiteDatabase database,int oldVersion,int newVersion){
        Log.w(MyDatabaseHelper.class.getName(),
                         "Upgrading database from version " + oldVersion + " to "
                         + newVersion + ", which will destroy all old data");
        database.execSQL("DROP TABLE IF EXISTS MyEmployees");
        onCreate(database);
    }
}

Now you can use this class as below,

public class MyDB{  

    private MyDatabaseHelper dbHelper;  

    private SQLiteDatabase database;  

    public final static String EMP_TABLE="MyEmployees"; // name of table 

    public final static String EMP_ID="_id"; // id value for employee
    public final static String EMP_NAME="name";  // name of employee

    /** 
     * 
     * @param context 
     */  
    public MyDB(Context context){  
        dbHelper = new MyDatabaseHelper(context);  
        database = dbHelper.getWritableDatabase();  
    }


    public long createRecords(String id, String name){  
        ContentValues values = new ContentValues();  
        values.put(EMP_ID, id);  
        values.put(EMP_NAME, name);  
        return database.insert(EMP_TABLE, null, values);  
    }    

    public Cursor selectRecords() {
        String[] cols = new String[] {EMP_ID, EMP_NAME};  
        Cursor mCursor = database.query(true, EMP_TABLE,cols,null  
            , null, null, null, null, null);  
        if (mCursor != null) {  
            mCursor.moveToFirst();  
        }  
        return mCursor; // iterate to get each value.
    }
}

Now you can use MyDB class in you activity to have all the database operations. The create records will help you to insert the values similarly you can have your own functions for update and delete.

Just prepend sudo to the beginning of your command. As stated before, an installation runs some scripts that might be dangerous but I saw installing globally helps a lot and is way simpler.

Run sudo npm install -g less

I prefer this solution using the csv module from the standard library and the with statement to avoid leaving the file open.

The key point is using 'a' for appending when you open the file.

import csv   
fields=['first','second','third']
with open(r'name', 'a') as f:
    writer = csv.writer(f)
    writer.writerow(fields)

If you are using Python 2.7 you may experience superfluous new lines in Windows. You can try to avoid them using 'ab' instead of 'a' this will, however, cause you TypeError: a bytes-like object is required, not 'str' in python and CSV in Python 3.6. Adding the newline='', as Natacha suggests, will cause you a backward incompatibility between Python 2 and 3.

TCPDF is PHP class for generating pdf documents.Here we will learn TCPDF integration with CodeIgniter.we will use following step for TCPDF integration with CodeIgniter.

Step 1

To Download TCPDF Click Here.

Step 2

Unzip the above download inside application/libraries/tcpdf.

Step 3

Create a new file inside application/libraries/Pdf.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
require_once dirname(__FILE__) . '/tcpdf/tcpdf.php';
class Pdf extends TCPDF
{ function __construct() { parent::__construct(); }
}
/*Author:Tutsway.com */
/* End of file Pdf.php */
/* Location: ./application/libraries/Pdf.php */

Step 4

Create Controller file inside application/controllers/pdfexample.php.

 <?php
    class pdfexample extends CI_Controller{ 
    function __construct()
    { parent::__construct(); } function index() {
    $this->load->library('Pdf');
    $pdf = new Pdf('P', 'mm', 'A4', true, 'UTF-8', false);
    $pdf->SetTitle('Pdf Example');
    $pdf->SetHeaderMargin(30);
    $pdf->SetTopMargin(20);
    $pdf->setFooterMargin(20);
    $pdf->SetAutoPageBreak(true);
    $pdf->SetAuthor('Author');
    $pdf->SetDisplayMode('real', 'default');
    $pdf->Write(5, 'CodeIgniter TCPDF Integration');
    $pdf->Output('pdfexample.pdf', 'I'); }
    }
    ?>

It is working for me. I have taken reference from http://www.tutsway.com/codeignitertcpdf.php

No need for that much code.

You can do all this stuff without coding so much by using only viewpager with tablayout.

Your main Layout:

<RelativeLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:app="http://schemas.android.com/apk/res-auto"
   android:layout_width="match_parent"
   android:layout_height="wrap_content">

   <android.support.v4.view.ViewPager
       android:id="@+id/pager"
       android:layout_width="match_parent"
       android:layout_height="match_parent">

   </android.support.v4.view.ViewPager>
   <android.support.design.widget.TabLayout
       android:id="@+id/tabDots"
       android:layout_alignParentBottom="true"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       app:tabBackground="@drawable/tab_selector"
       app:tabGravity="center"
       app:tabIndicatorHeight="0dp"/>
</RelativeLayout>

Hook up your UI elements inactivity or fragment as follows:

Java Code:

mImageViewPager = (ViewPager) findViewById(R.id.pager);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabDots);
tabLayout.setupWithViewPager(mImageViewPager, true);

That's it, you are good to go.

You will need to create the following xml resource file in the drawable folder.

tab_indicator_selected.xml

<?xml version="1.0" encoding="utf-8"?>
<shape
    android:innerRadius="0dp"
    android:shape="ring"
    android:thickness="4dp"
    android:useLevel="false"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="@color/colorAccent"/>
</shape>

tab_indicator_default.xml

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android"
            android:innerRadius="0dp"
            android:shape="oval"
            android:thickness="2dp"
            android:useLevel="false">
            <solid android:color="@android:color/darker_gray"/>
    </shape>

tab_selector.xml

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/tab_indicator_selected"
          android:state_selected="true"/>

    <item android:drawable="@drawable/tab_indicator_default"/>
</selector>

Feeling as lazy as I am? Well, all the above code is converted into a library! Usage Add the following in your gradle: implementation 'com.chabbal:slidingdotsplash:1.0.2' Add the following to your Activity or Fragment layout.

<com.chabbal.slidingdotsplash.SlidingSplashView
        android:id="@+id/splash"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:imageResources="@array/img_id_arr"/>

Create an integer array in strings.xml e.g.

<integer-array name="img_id_arr">
   <item>@drawable/img1</item>
   <item>@drawable/img2</item>
   <item>@drawable/img3</item>
   <item>@drawable/img4</item>
</integer-array>

Done! Extra in order to listen page changes use addOnPageChangeListener(listener); Github link.

Based on previous answers, here are reusable "procedures" and a usage example for calculating the elapsed time:

@echo off
setlocal

set starttime=%TIME%
echo Start Time: %starttime%

REM ---------------------------------------------
REM --- PUT THE CODE YOU WANT TO MEASURE HERE ---
REM ---------------------------------------------

set endtime=%TIME%
echo End Time: %endtime%
call :elapsed_time %starttime% %endtime% duration
echo Duration: %duration%

endlocal
echo on & goto :eof

REM --- HELPER PROCEDURES ---

:time_to_centiseconds

   set /A "_result=(((%%a*60)+1%%b %% 100)*60+1%%c %% 100)*100+1%%d %% 100"
)

Weird reason I've never seen before: If you're using a "parent > child" selector outside of the media query (in Firefox 69) it could break the media query. I'm not sure why this happens, but for my scenario this did not work...

@media whatever {
    #child { display: none; }
}

But adding the parent to match some other CSS further up the page, this works...

#parent > #child { display: none; }

Seems like specifying the parent should not matter, since an id is very specific and there should be no ambiguity. Maybe it's a bug in Firefox?

Even though I'm way late to the party here, I'm going to chime in with some useful tricks from my hardware days. All of these assume 2's compliment representation for signed numbers.

int negate = ~i+1;
int positiveMagnitude = (i ^ (i>>31)) - (i>>31);
int negativeMagnitude = (i>>31) - (i ^ (i>>31));

Try this code

import re
re.sub(r'[^\x00-\x7F]+','','paste your string here').decode('utf-8','ignore').strip()

I got that message after attached an attribute to a method

[webMethod]
public void DoSomething()
{
}

But the correct way was this:

[webMethod()] // Note the Parentheses 
public void DoSomething()
{
}

Here is the mistake: as someone said before, you are using org.pharmacy insted of com.pharmacy in componentscan

    package **com**.pharmacy.config;

    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.context.annotation.ComponentScan;


    @SpringBootApplication
    @ComponentScan("**org**.pharmacy")
    public class SpringBootRunner {

For posterity, I think this is quicker:

a = np.array([np.array(list()) for _ in y])

You might even be able to pass in a generator (i.e. [] -> ()), in which case the inner list is never fully stored in memory.

Responding to comment below:

>>> import numpy as np
>>> y = range(10)
>>> a = np.array([np.array(list) for _ in y])
>>> a
array([array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object),
       array(<type 'list'>, dtype=object)], dtype=object)

I'm Maybe kind of late but here is a way to have a redirect for your website and another link if it does not do in auto redirect for them,

<meta charset="UTF-8" />
<meta http-equiv="refresh" content="5; url=YOUR_URL_HERE" />
<script type="text/javascript">
  window.location.href = "site";
</script>
<title>Page Redirection</title>

<!-- Note: don't tell people to `click` the link, just tell them that it is a link. -->
If you are not redirected automatically, follow this <a href="/site">Link</a>

You can always do it programmatically as suggested by the other answers over here. But for development purpose, I find this Plugin very helpful as it speeds up my development significantly.

PLUGIN: ADB Idea

It provides you with features to Clear App Data and Revoke Permission from your Android Studio itself, just with click of a button.

You're actually seeing the top margin of the #inner element collapse into the top edge of the #outer element, leaving only the #outer margin intact (albeit not shown in your images). The top edges of both boxes are flush against each other because their margins are equal.

Here are the relevant points from the W3C spec:

8.3.1 Collapsing margins

In CSS, the adjoining margins of two or more boxes (which might or might not be siblings) can combine to form a single margin. Margins that combine this way are said to collapse, and the resulting combined margin is called a collapsed margin.

Adjoining vertical margins collapse [...]

Two margins are adjoining if and only if:

• both belong to in-flow block-level boxes that participate in the same block formatting context
• no line boxes, no clearance, no padding and no border separate them
• both belong to vertically-adjacent box edges, i.e. form one of the following pairs:
  • top margin of a box and top margin of its first in-flow child

You can do any of the following to prevent the margin from collapsing:

• Float either of your div elements
• Make either of your div elements inline blocks
• Set overflow of #outer to auto (or any value other than visible)

The reason the above options prevent the margin from collapsing is because:

• Margins between a floated box and any other box do not collapse (not even between a float and its in-flow children).
• Margins of elements that establish new block formatting contexts (such as floats and elements with 'overflow' other than 'visible') do not collapse with their in-flow children.
• Margins of inline-block boxes do not collapse (not even with their in-flow children).

The left and right margins behave as you expect because:

Horizontal margins never collapse.

For convenience, a simple function wrapping the two methods from os.path :

def filename(path):
  """Return file name without extension from path.

  See https://docs.python.org/3/library/os.path.html
  """
  import os.path
  b = os.path.split(path)[1]  # path, *filename*
  f = os.path.splitext(b)[0]  # *file*, ext
  #print(path, b, f)
  return f

Tested with Python 3.5.

Use a Profiler

Your approach will work nevertheless, but if you are looking for more sophisticated approaches. I'd suggest using a C# Profiler.

The advantages they have is:

• You can even get a statement level breakup
• No changes required in your codebase
• Instrumentions generally have very less overhead, hence very accurate results can be obtained.

There are many available open-source as well.

The connection to adb is down, and a severe error has occured.

[2011-12-19 11:45:09 - RayhReport] You must restart adb and Eclipse.
[2011-12-19 11:45:09 - RayhReport] Please ensure that adb is correctly located at 'D:\android-sdk-windows\tools\adb.exe' and can be executed.

When you go to D:\android-sdk-windows\tools\adb.exe path then you see the text file,the name of file is "adb_has_moved" thats means your adb.exe is moved to platform-tools copied down the adb.exe and paste in tools folder and run it. I'm sure it works.

LIMIT 1 is what you want. Just keep in mind this returns the first record in the result set regardless of order (unless you specify an order clause in an outer query).

When you try to execute a program in unix (one with the executable bit set), the operating system will look at the first few bytes of the file. These form the so-called "magic number", which can be used to decide the format of the program and how to execute it.

#! corresponds to the magic number 0x2321 (look it up in an ascii table). When the system sees that the magic number, it knows that it is dealing with a text script and reads until the next \n (there is a limit, but it escapes me atm). Having identified the interpreter (the first argument after the shebang) it will call the interpreter.

Other files also have magic numbers. Try looking at a bitmap (.BMP) file via less and you will see the first two characters are BM. This magic number denotes that the file is indeed a bitmap.

If you NEED to do it on your phone, I use a terminal emulator and standard linux commands.

Example:

1. su
2. cd data
3. cd com.yourappp
4. ls or cd into cache/shared_prefs

I learned this shortcut from working at the network deployment position. It helped me so much, I figured I will share this secret with everyone. So far, I have not able to find an easier way online that I know of.

For example a network 192.115.103.64 /27, what is the range?

just remember that subnet mask is 0, 128, 192, 224, 240, 248, 252, 254, 255

255.255.255.255 11111111.11111111.11111111.11111111 /32

255.255.255.254 11111111.11111111.11111111.11111110 /31

255.255.255.252 11111111.11111111.11111111.11111100 /30

255.255.255.248 11111111.11111111.11111111.11111000 /29

255.255.255.240 11111111.11111111.11111111.11110000 /28

255.255.255.224 11111111.11111111.11111111.11100000 /27

255.255.255.192 11111111.11111111.11111111.11000000 /26

255.255.255.128 11111111.11111111.11111111.10000000 /25

255.255.255.0 11111111.11111111.11111111.00000000 /24

from /27 we know that (11111111.11111111.11111111.11100000). Counting from the left, it is the third number from the last octet, which equal 255.255.255.224 subnet mask. (Don't count 0, 0 is /24) so 128, 192, 224..etc

Here where the math comes in:

use the subnet mask - subnet mask of the previous listed subnet mask in this case 224-192=32

We know 192.115.103.64 is the network: 64 + 32 = 96 (the next network for /27)

which means we have .0 .32. 64. 96. 128. 160. 192. 224. (Can't use 256 because it is .255)

Here is the range 64 -- 96.

network is 64.

first host is 65.(first network +1)

Last host is 94. (broadcast -1)

broadcast is 95. (last network -1)

If you're okay with ES2017, await is good:

const DEF_DELAY = 1000;

function sleep(ms) {
  return new Promise(resolve => setTimeout(resolve, ms || DEF_DELAY));
}

await sleep(100);

Note that the await part needs to be in an async function:

//IIAFE (immediately invoked async function expression)
(async()=>{
  //Do some stuff
  await sleep(100);
  //Do some more stuff
})()

Another solution, since April 2015 is Git Large File Storage (LFS) (by GitHub).

It uses git-lfs (see git-lfs.github.com) and tested with a server supporting it: lfs-test-server:
You can store metadata only in the git repo, and the large file elsewhere.

Here's a great reason to use objectForKey: wherever possible instead of valueForKey: - valueForKey: with an unknown key will throw NSUnknownKeyException saying "this class is not key value coding-compliant for the key ".

Use the not function instead:

var lastOpenSite = $(this).siblings().not('.closedTab');

hasClass only tests whether an element has a class, not will remove elements from the selected set matching the provided selector.

The Spring security filter chain is a very complex and flexible engine.

Key filters in the chain are (in the order)

• SecurityContextPersistenceFilter (restores Authentication from JSESSIONID)
• UsernamePasswordAuthenticationFilter (performs authentication)
• ExceptionTranslationFilter (catch security exceptions from FilterSecurityInterceptor)
• FilterSecurityInterceptor (may throw authentication and authorization exceptions)

Looking at the current stable release 4.2.1 documentation, section 13.3 Filter Ordering you could see the whole filter chain's filter organization:

13.3 Filter Ordering

The order that filters are defined in the chain is very important. Irrespective of which filters you are actually using, the order should be as follows:

1. ChannelProcessingFilter, because it might need to redirect to a different protocol

2. SecurityContextPersistenceFilter, so a SecurityContext can be set up in the SecurityContextHolder at the beginning of a web request, and any changes to the SecurityContext can be copied to the HttpSession when the web request ends (ready for use with the next web request)

3. ConcurrentSessionFilter, because it uses the SecurityContextHolder functionality and needs to update the SessionRegistry to reflect ongoing requests from the principal

4. Authentication processing mechanisms - UsernamePasswordAuthenticationFilter, CasAuthenticationFilter, BasicAuthenticationFilter etc - so that the SecurityContextHolder can be modified to contain a valid Authentication request token

5. The SecurityContextHolderAwareRequestFilter, if you are using it to install a Spring Security aware HttpServletRequestWrapper into your servlet container

6. The JaasApiIntegrationFilter, if a JaasAuthenticationToken is in the SecurityContextHolder this will process the FilterChain as the Subject in the JaasAuthenticationToken

7. RememberMeAuthenticationFilter, so that if no earlier authentication processing mechanism updated the SecurityContextHolder, and the request presents a cookie that enables remember-me services to take place, a suitable remembered Authentication object will be put there

8. AnonymousAuthenticationFilter, so that if no earlier authentication processing mechanism updated the SecurityContextHolder, an anonymous Authentication object will be put there

9. ExceptionTranslationFilter, to catch any Spring Security exceptions so that either an HTTP error response can be returned or an appropriate AuthenticationEntryPoint can be launched

10. FilterSecurityInterceptor, to protect web URIs and raise exceptions when access is denied

Now, I'll try to go on by your questions one by one:

I'm confused how these filters are used. Is it that for the spring provided form-login, UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not? Does the form-login namespace element auto-configure these filters? Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

Once you are configuring a <security-http> section, for each one you must at least provide one authentication mechanism. This must be one of the filters which match group 4 in the 13.3 Filter Ordering section from the Spring Security documentation I've just referenced.

This is the minimum valid security:http element which can be configured:

<security:http authentication-manager-ref="mainAuthenticationManager" 
               entry-point-ref="serviceAccessDeniedHandler">
    <security:intercept-url pattern="/sectest/zone1/**" access="hasRole('ROLE_ADMIN')"/>
</security:http>

Just doing it, these filters are configured in the filter chain proxy:

{
        "1": "org.springframework.security.web.context.SecurityContextPersistenceFilter",
        "2": "org.springframework.security.web.context.request.async.WebAsyncManagerIntegrationFilter",
        "3": "org.springframework.security.web.header.HeaderWriterFilter",
        "4": "org.springframework.security.web.csrf.CsrfFilter",
        "5": "org.springframework.security.web.savedrequest.RequestCacheAwareFilter",
        "6": "org.springframework.security.web.servletapi.SecurityContextHolderAwareRequestFilter",
        "7": "org.springframework.security.web.authentication.AnonymousAuthenticationFilter",
        "8": "org.springframework.security.web.session.SessionManagementFilter",
        "9": "org.springframework.security.web.access.ExceptionTranslationFilter",
        "10": "org.springframework.security.web.access.intercept.FilterSecurityInterceptor"
    }

Note: I get them by creating a simple RestController which @Autowires the FilterChainProxy and returns it's contents:

    @Autowired
    private FilterChainProxy filterChainProxy;

    @Override
    @RequestMapping("/filterChain")
    public @ResponseBody Map<Integer, Map<Integer, String>> getSecurityFilterChainProxy(){
        return this.getSecurityFilterChainProxy();
    }

    public Map<Integer, Map<Integer, String>> getSecurityFilterChainProxy(){
        Map<Integer, Map<Integer, String>> filterChains= new HashMap<Integer, Map<Integer, String>>();
        int i = 1;
        for(SecurityFilterChain secfc :  this.filterChainProxy.getFilterChains()){
            //filters.put(i++, secfc.getClass().getName());
            Map<Integer, String> filters = new HashMap<Integer, String>();
            int j = 1;
            for(Filter filter : secfc.getFilters()){
                filters.put(j++, filter.getClass().getName());
            }
            filterChains.put(i++, filters);
        }
        return filterChains;
    }

Here we could see that just by declaring the <security:http> element with one minimum configuration, all the default filters are included, but none of them is of a Authentication type (4th group in 13.3 Filter Ordering section). So it actually means that just by declaring the security:http element, the SecurityContextPersistenceFilter, the ExceptionTranslationFilter and the FilterSecurityInterceptor are auto-configured.

In fact, one authentication processing mechanism should be configured, and even security namespace beans processing claims for that, throwing an error during startup, but it can be bypassed adding an entry-point-ref attribute in <http:security>

If I add a basic <form-login> to the configuration, this way:

<security:http authentication-manager-ref="mainAuthenticationManager">
    <security:intercept-url pattern="/sectest/zone1/**" access="hasRole('ROLE_ADMIN')"/>
    <security:form-login />
</security:http>

Now, the filterChain will be like this:

{
        "1": "org.springframework.security.web.context.SecurityContextPersistenceFilter",
        "2": "org.springframework.security.web.context.request.async.WebAsyncManagerIntegrationFilter",
        "3": "org.springframework.security.web.header.HeaderWriterFilter",
        "4": "org.springframework.security.web.csrf.CsrfFilter",
        "5": "org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter",
        "6": "org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter",
        "7": "org.springframework.security.web.savedrequest.RequestCacheAwareFilter",
        "8": "org.springframework.security.web.servletapi.SecurityContextHolderAwareRequestFilter",
        "9": "org.springframework.security.web.authentication.AnonymousAuthenticationFilter",
        "10": "org.springframework.security.web.session.SessionManagementFilter",
        "11": "org.springframework.security.web.access.ExceptionTranslationFilter",
        "12": "org.springframework.security.web.access.intercept.FilterSecurityInterceptor"
    }

Now, this two filters org.springframework.security.web.authentication.UsernamePasswordAuthenticationFilter and org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter are created and configured in the FilterChainProxy.

So, now, the questions:

Is it that for the spring provided form-login, UsernamePasswordAuthenticationFilter is only used for /login, and latter filters are not?

Yes, it is used to try to complete a login processing mechanism in case the request matches the UsernamePasswordAuthenticationFilter url. This url can be configured or even changed it's behaviour to match every request.

You could too have more than one Authentication processing mechanisms configured in the same FilterchainProxy (such as HttpBasic, CAS, etc).

Does the form-login namespace element auto-configure these filters?

No, the form-login element configures the UsernamePasswordAUthenticationFilter, and in case you don't provide a login-page url, it also configures the org.springframework.security.web.authentication.ui.DefaultLoginPageGeneratingFilter, which ends in a simple autogenerated login page.

The other filters are auto-configured by default just by creating a <security:http> element with no security:"none" attribute.

Does every request (authenticated or not) reach FilterSecurityInterceptor for non-login url?

Every request should reach it, as it is the element which takes care of whether the request has the rights to reach the requested url. But some of the filters processed before might stop the filter chain processing just not calling FilterChain.doFilter(request, response);. For example, a CSRF filter might stop the filter chain processing if the request has not the csrf parameter.

What if I want to secure my REST API with JWT-token, which is retrieved from login? I must configure two namespace configuration http tags, rights? Other one for /login with UsernamePasswordAuthenticationFilter, and another one for REST url's, with custom JwtAuthenticationFilter.

No, you are not forced to do this way. You could declare both UsernamePasswordAuthenticationFilter and the JwtAuthenticationFilter in the same http element, but it depends on the concrete behaviour of each of this filters. Both approaches are possible, and which one to choose finnally depends on own preferences.

Does configuring two http elements create two springSecurityFitlerChains?

Yes, that's true

Is UsernamePasswordAuthenticationFilter turned off by default, until I declare form-login?

Yes, you could see it in the filters raised in each one of the configs I posted

How do I replace SecurityContextPersistenceFilter with one, which will obtain Authentication from existing JWT-token rather than JSESSIONID?

You could avoid SecurityContextPersistenceFilter, just configuring session strategy in <http:element>. Just configure like this:

<security:http create-session="stateless" >

Or, In this case you could overwrite it with another filter, this way inside the <security:http> element:

<security:http ...>  
   <security:custom-filter ref="myCustomFilter" position="SECURITY_CONTEXT_FILTER"/>    
</security:http>
<beans:bean id="myCustomFilter" class="com.xyz.myFilter" />

EDIT:

One question about "You could too have more than one Authentication processing mechanisms configured in the same FilterchainProxy". Will the latter overwrite the authentication performed by first one, if declaring multiple (Spring implementation) authentication filters? How this relates to having multiple authentication providers?

This finally depends on the implementation of each filter itself, but it's true the fact that the latter authentication filters at least are able to overwrite any prior authentication eventually made by preceding filters.

But this won't necesarily happen. I have some production cases in secured REST services where I use a kind of authorization token which can be provided both as a Http header or inside the request body. So I configure two filters which recover that token, in one case from the Http Header and the other from the request body of the own rest request. It's true the fact that if one http request provides that authentication token both as Http header and inside the request body, both filters will try to execute the authentication mechanism delegating it to the manager, but it could be easily avoided simply checking if the request is already authenticated just at the begining of the doFilter() method of each filter.

Having more than one authentication filter is related to having more than one authentication providers, but don't force it. In the case I exposed before, I have two authentication filter but I only have one authentication provider, as both of the filters create the same type of Authentication object so in both cases the authentication manager delegates it to the same provider.

And opposite to this, I too have a scenario where I publish just one UsernamePasswordAuthenticationFilter but the user credentials both can be contained in DB or LDAP, so I have two UsernamePasswordAuthenticationToken supporting providers, and the AuthenticationManager delegates any authentication attempt from the filter to the providers secuentially to validate the credentials.

So, I think it's clear that neither the amount of authentication filters determine the amount of authentication providers nor the amount of provider determine the amount of filters.

Also, documentation states SecurityContextPersistenceFilter is responsible of cleaning the SecurityContext, which is important due thread pooling. If I omit it or provide custom implementation, I have to implement the cleaning manually, right? Are there more similar gotcha's when customizing the chain?

I did not look carefully into this filter before, but after your last question I've been checking it's implementation, and as usually in Spring, nearly everything could be configured, extended or overwrited.

The SecurityContextPersistenceFilter delegates in a SecurityContextRepository implementation the search for the SecurityContext. By default, a HttpSessionSecurityContextRepository is used, but this could be changed using one of the constructors of the filter. So it may be better to write an SecurityContextRepository which fits your needs and just configure it in the SecurityContextPersistenceFilter, trusting in it's proved behaviour rather than start making all from scratch.

Try this

<form method="post" id="reg" name="reg" action="<?php echo htmlspecialchars($_SERVER['PHP_SELF']);?>"

Works well :)

With netcat and awk you can handle the server response manually:

if netcat 127.0.0.1 8080 <<EOF | awk 'NR==1{if ($2 == "500") exit 0; exit 1;}'; then
GET / HTTP/1.1
Host: www.example.com

EOF

    apache2ctl restart;
fi

Assuming two decimal places on your percentages, the data type you use depends on how you plan to store your percentages. If you are going to store their fractional equivalent (e.g. 100.00% stored as 1.0000), I would store the data in a decimal(5,4) data type with a CHECK constraint that ensures that the values never exceed 1.0000 (assuming that is the cap) and never go below 0 (assuming that is the floor). If you are going to store their face value (e.g. 100.00% is stored as 100.00), then you should use decimal(5,2) with an appropriate CHECK constraint. Combined with a good column name, it makes it clear to other developers what the data is and how the data is stored in the column.

If lakes is your DataFrame, you can do something like

area_dict = dict(zip(lakes.area, lakes.count))

Many answers to the question already. For me the problem was two fold:

1. when I expand my routes:

   devise_for :users do 
      get '/users/sign_out' => 'devise/sessions#destroy'
   end
   

2. I was getting warning that this is depreciated so I have replaced it with:

   devise_scope :users do
      get '/users/sign_out' => 'devise/sessions#destroy'
   end
   

3. I thought I will remove my jQuery. Bad choice. Devise is using jQuery to "fake" DELETE request and send it as GET. Therefore you need to:

   //= require jquery
   //= require jquery_ujs
   

4. and of course same link as many mentioned before:

   <%= link_to "Sign out", destroy_user_session_path, :method => :delete %>
   

In some cases it is tied to how the field is used. In some DB engines the field differences determine how (and if) you search for text in the field. CharFields are typically used for things that are searchable, like if you want to search for "one" in the string "one plus two". Since the strings are shorter they are less time consuming for the engine to search through. TextFields are typically not meant to be searched through (like maybe the body of a blog) but are meant to hold large chunks of text. Now most of this depends on the DB Engine and like in Postgres it does not matter.

Even if it does not matter, if you use ModelForms you get a different type of editing field in the form. The ModelForm will generate an HTML form the size of one line of text for a CharField and multiline for a TextField.

I would apply this rule to all input fields of type text, so it doesn't need to be duplicated later:

input[type=text]::-ms-clear { display: none; }

One can even get less specific by using just:

::-ms-clear { display: none; }

I have used the later even before adding this answer, but thought that most people would prefer to be more specific than that. Both solutions work fine.

The signature of main is:

int main(int argc, char **argv);

argc refers to the number of command line arguments passed in, which includes the actual name of the program, as invoked by the user. argv contains the actual arguments, starting with index 1. Index 0 is the program name.

So, if you ran your program like this:

./program hello world

Then:

• argc would be 3.
• argv[0] would be "./program".
• argv[1] would be "hello".
• argv[2] would be "world".

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

the react docs explain this nicely in the documentation, you have to use process.env.PUBLIC_URL with images placed in the public folder. See here for more info

return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;

Just put .htaccess into the folder you want to restrict

## no access to this folder

# Apache 2.4
<IfModule mod_authz_core.c>
    Require all denied
</IfModule>

# Apache 2.2
<IfModule !mod_authz_core.c>
    Order Allow,Deny
    Deny from all

We recently implemented a system that needs to handle values in multiple currencies and convert between them, and figured out a few things the hard way.

NEVER USE FLOATING POINT NUMBERS FOR MONEY

Floating point arithmetic introduces inaccuracies that may not be noticed until they've screwed something up. All values should be stored as either integers or fixed-decimal types, and if you choose to use a fixed-decimal type then make sure you understand exactly what that type does under the hood (ie, does it internally use an integer or floating point type).

When you do need to do calculations or conversions:

1. Convert values to floating point
2. Calculate new value
3. Round the number and convert it back to an integer

When converting a floating point number back to an integer in step 3, don't just cast it - use a math function to round it first. This will usually be round, though in special cases it could be floor or ceil. Know the difference and choose carefully.

Store the type of a number alongside the value

This may not be as important for you if you're only handling one currency, but it was important for us in handling multiple currencies. We used the 3-character code for a currency, such as USD, GBP, JPY, EUR, etc.

Depending on the situation, it may also be helpful to store:

• Whether the number is before or after tax (and what the tax rate was)
• Whether the number is the result of a conversion (and what it was converted from)

Know the accuracy bounds of the numbers you're dealing with

For real values, you want to be as precise as the smallest unit of the currency. This means you have no values smaller than a cent, a penny, a yen, a fen, etc. Don't store values with higher accuracy than that for no reason.

Internally, you may choose to deal with smaller values, in which case that's a different type of currency value. Make sure your code knows which is which and doesn't get them mixed up. Avoid using floating point values even here.

Adding all those rules together, we decided on the following rules. In running code, currencies are stored using an integer for the smallest unit.

class Currency {
   String code;       //  eg "USD"
   int value;         //  eg 2500
   boolean converted;
}

class Price {
   Currency grossValue;
   Currency netValue;
   Tax taxRate;
}

In the database, the values are stored as a string in the following format:

USD:2500

That stores the value of $25.00. We were able to do that only because the code that deals with currencies doesn't need to be within the database layer itself, so all values can be converted into memory first. Other situations will no doubt lend themselves to other solutions.

And in case I didn't make it clear earlier, don't use float!

This Question is already thoroughly answered, so I think a runtime analysis of the proposed methods would be of interest (It was for me, anyway). I will also look at the behavior of the methods at the center and the edges of the noisy dataset.

TL;DR

                    | runtime in s | runtime in s
method              | python list  | numpy array
--------------------|--------------|------------
kernel regression   | 23.93405     | 22.75967 
lowess              |  0.61351     |  0.61524 
naive average       |  0.02485     |  0.02326 
others*             |  0.00150     |  0.00150 
fft                 |  0.00021     |  0.00021 
numpy convolve      |  0.00017     |  0.00015 

*savgol with different fit functions and some numpy methods

Kernel regression scales badly, Lowess is a bit faster, but both produce smooth curves. Savgol is a middle ground on speed and can produce both jumpy and smooth outputs, depending on the grade of the polynomial. FFT is extremely fast, but only works on periodic data.

Moving average methods with numpy are faster but obviously produce a graph with steps in it.

Setup

I generated 1000 data points in the shape of a sin curve:

size = 1000
x = np.linspace(0, 4 * np.pi, size)
y = np.sin(x) + np.random.random(size) * 0.2
data = {"x": x, "y": y}

I pass these into a function to measure the runtime and plot the resulting fit:

def test_func(f, label):  # f: function handle to one of the smoothing methods
    start = time()
    for i in range(5):
        arr = f(data["y"], 20)
    print(f"{label:26s} - time: {time() - start:8.5f} ")
    plt.plot(data["x"], arr, "-", label=label)

I tested many different smoothing fuctions. arr is the array of y values to be smoothed and span the smoothing parameter. The lower, the better the fit will approach the original data, the higher, the smoother the resulting curve will be.

def smooth_data_convolve_my_average(arr, span):
    re = np.convolve(arr, np.ones(span * 2 + 1) / (span * 2 + 1), mode="same")

    # The "my_average" part: shrinks the averaging window on the side that 
    # reaches beyond the data, keeps the other side the same size as given 
    # by "span"
    re[0] = np.average(arr[:span])
    for i in range(1, span + 1):
        re[i] = np.average(arr[:i + span])
        re[-i] = np.average(arr[-i - span:])
    return re

def smooth_data_np_average(arr, span):  # my original, naive approach
    return [np.average(arr[val - span:val + span + 1]) for val in range(len(arr))]

def smooth_data_np_convolve(arr, span):
    return np.convolve(arr, np.ones(span * 2 + 1) / (span * 2 + 1), mode="same")

def smooth_data_np_cumsum_my_average(arr, span):
    cumsum_vec = np.cumsum(arr)
    moving_average = (cumsum_vec[2 * span:] - cumsum_vec[:-2 * span]) / (2 * span)

    # The "my_average" part again. Slightly different to before, because the
    # moving average from cumsum is shorter than the input and needs to be padded
    front, back = [np.average(arr[:span])], []
    for i in range(1, span):
        front.append(np.average(arr[:i + span]))
        back.insert(0, np.average(arr[-i - span:]))
    back.insert(0, np.average(arr[-2 * span:]))
    return np.concatenate((front, moving_average, back))

def smooth_data_lowess(arr, span):
    x = np.linspace(0, 1, len(arr))
    return sm.nonparametric.lowess(arr, x, frac=(5*span / len(arr)), return_sorted=False)

def smooth_data_kernel_regression(arr, span):
    # "span" smoothing parameter is ignored. If you know how to 
    # incorporate that with kernel regression, please comment below.
    kr = KernelReg(arr, np.linspace(0, 1, len(arr)), 'c')
    return kr.fit()[0]

def smooth_data_savgol_0(arr, span):  
    return savgol_filter(arr, span * 2 + 1, 0)

def smooth_data_savgol_1(arr, span):

Especially kernel regression is very slow to compute over 1k elements, lowess also fails when the dataset becomes much larger. numpy convolve and fft are especially fast. I did not investigate the runtime behavior (O(n)) with increasing or decreasing sample size.

Edge behavior

I'll separate this part into two, to keep image understandable.

Numpy based methods + savgol 0:

These methods calculate an average of the data, the graph is not smoothed. They all (with the exception of numpy.cumsum) result in the same graph when the window that is used to calculate the average does not touch the edge of the data. The discrepancy to numpy.cumsum is most likely due to a 'off by one' error in the window size.

There are different edge behaviours when the method has to work with less data:

• savgol 0: continues with a constant to the edge of the data (savgol 1 and savgol 2 end with a line and parabola respectively)
• numpy average: stops when the window reaches the left side of the data and fills those places in the array with Nan, same behaviour as my_average method on the right side
• numpy convolve: follows the data pretty accurately. I suspect the window size is reduced symmetrically when one side of the window reaches the edge of the data
• my_average/me: my own method that I implemented, because I was not satisfied with the other ones. Simply shrinks the part of the window that is reaching beyond the data to the edge of the data, but keeps the window to the other side the original size given with span

Complicated methods:

These methods all end with a nice fit to the data. savgol 1 ends with a line, savgol 2 with a parabola.

Curve behaviour

To showcase the behaviour of the different methods in the middle of the data.

The different savgol and average filters produce a rough line, lowess, fft and kernel regression produce a smooth fit. lowess appears to cut corners when the data changes.

Motivation

I have a Raspberry Pi logging data for fun and the visualization proved to be a small challenge. All data points, except RAM usage and ethernet traffic are only recorded in discrete steps and/or inherently noisy. For example the temperature sensor only outputs whole degrees, but differs by up to two degrees between consecutive measurements. No useful information can be gained from such a scatter plot. To visualize the data I therefore needed some method that is not too computationally expensive and produced a moving average. I also wanted nice behavior at the edges of the data, as this especially impacts the latest info when looking at live data. I settled on the numpy convolve method with my_average to improve the edge behavior.

innerHTML is a property of every element. It tells you what is between the starting and ending tags of the element, and it also let you sets the content of the element.

property describes an aspect of an object. It is something an object has as opposed to something an object does.

<p id="myParagraph">
This is my paragraph.
</p>

You can select the paragraph and then change the value of it's innerHTML with the following command:

document.getElementById("myParagraph").innerHTML = "This is my paragraph";

For anyone that is using MariaDB instead of MySQL, the solution is to install the libmariadbclient-dev package and create a symbolic link to the config file with the correct name.

For example this worked for me:

ln -s /usr/bin/mariadb_config /usr/bin/mysql_config

If you're OK with a JavaScript solution, there's a jQuery plug-in to do this in a cross-browser fashion - see http://azgtech.wordpress.com/2009/07/26/text-overflow-ellipsis-for-firefox-via-jquery/

This error can come not only because of the Date conversions

This error can come when we try to pass date whereas varchar is expected
or
when we try to pass varchar whereas date is expected.

Use to_char(sysdate,'YYYY-MM-DD') when varchar is expected

Try to use ; instead of GO. It worked for me for 2008 R2 version

DECLARE @GLOBAL_VAR_1 INT = Value_1;

DECLARE @GLOBAL_VAR_2 INT = Value_2;

USE "DB_1";
SELECT * FROM "TABLE" WHERE "COL_!" = @GLOBAL_VAR_1 

AND "COL_2" = @GLOBAL_VAR_2;

USE "DB_2";

SELECT * FROM "TABLE" WHERE "COL_!" = @GLOBAL_VAR_2;

To me it happened in DogController that autowired DogService that autowired DogRepository. Dog class used to have field name but I changed it to coolName, but didn't change methods in DogRepository: Dog findDogByName(String name). I change that method to Dog findDogByCoolName(String name) and now it works.

Hope this helps:

I realize this is a rather late post but still a possible solution for the OP. I use IE9 on Win 7 and have been having Adobe Reader's grey screen issues for several months when trying to open pdf bank and credit card statements online. I could open everything in Firefox or Opera but not IE. I finally tried PDF-Viewer, set it as the default pdf viewer in its preferences and no more problems. I'm sure there are other free viewers out there, like Foxit, PDF-Xchange, etc., that will give better results than Reader with less headaches. Adobe is like some of the other big companies that develop software on a take it or leave it basis ... so I left it.

Setting position to relative does not work for me. It only works if I set the position of body to fixed:

document.body.style.position = "fixed";
document.body.style.overflowY = "hidden";
document.body.addEventListener('touchstart', function(e){ e.preventDefault()});

Thanks a bundle, guys. You are great.

I used Chuff's answer and modified it a little to do what I wanted.

I have 2 worksheets in the same workbook.

On 1st worksheet I have a list of SMS in 3 columns: phone number, date & time, message

Then I inserted a new blank column next to the phone number

On worksheet 2 I have two columns: phone number, name of person

Used the formula to check the cell on the left, and match against the range in worksheet 2, pick the name corresponding to the number and input it into the blank cell in worksheet 1.

Then just copy the formula down the whole column until last sms It worked beautifully.

=VLOOKUP(A3,Sheet2!$A$1:$B$31,2,0)

You can use a SqlDataAdapter:

    SqlDataAdapter adapter = new SqlDataAdapter();
    SqlCommand cmd = new SqlCommand("usp_GetABCD", sqlcon);
    cmd.CommandType = CommandType.StoredProcedure;
    adapter.SelectCommand = cmd;
    DataTable dt = new DataTable();
    adapter.Fill(dt);

AJAX stands for Asynchronous JavaScript and XML. Thus, the post to the server happens out-of-sync with the rest of the function. Try some code like this instead (it just breaks the shorthand $.post out into the longer $.ajax call and adds the async option).

var it_works = false;

$.ajax({
  type: 'POST',
  async: false,
  url: "some_file.php",
  data: "",
  success: function() {it_works = true;}
});

alert(it_works);

Hope this helps!

I have tried almost all the mentioned methods above, but the flexbox solution won't work correctly with Safari, and the grid layout methods won't work correctly with older versions of IE.

This solution fits all screens and is cross-browser compatible:

.container {margin:15px auto;}
.container ul {margin:0 10px;}
.container li {width:30%; display: table-cell; background-color:#f6f7f7;box-shadow: 0 2px 5px 0 rgba(0, 0, 0, 0.25);}

@media (max-width: 767px){
    .container li { display: inline-block; width:100%; min-height:auto!important;}
}

The above method will equal cells height, and for the smaller screens like mobile or tablet, we can use the @media method mentioned above.

This is the code with two bug fixes. The first bug fix was mentioned by Royi Namir in the comment on the accepted answer to this question. The bug is described on StackOverflow at Bug in Trigger Code. The second one was found by @Fandango68 and fixes columns with multiples words for their names.

The best way to do this would be to use the promise returning function as it is, like this

lookupValue(file).then(function(res) {
    // Write the code which depends on the `res.val`, here
});

The function which invokes an asynchronous function cannot wait till the async function returns a value. Because, it just invokes the async function and executes the rest of the code in it. So, when an async function returns a value, it will not be received by the same function which invoked it.

So, the general idea is to write the code which depends on the return value of an async function, in the async function itself.

On EF6.2, you can use HasIndex() to add indexes for migration through fluent API.

https://github.com/aspnet/EntityFramework6/issues/274

Example

modelBuilder
    .Entity<User>()
    .HasIndex(u => u.Email)
        .IsUnique();

On EF6.1 onwards, you can use IndexAnnotation() to add indexes for migration in your fluent API.

http://msdn.microsoft.com/en-us/data/jj591617.aspx#PropertyIndex

You must add reference to:

using System.Data.Entity.Infrastructure.Annotations;

Basic Example

Here is a simple usage, adding an index on the User.FirstName property

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .HasColumnAnnotation(IndexAnnotation.AnnotationName, new IndexAnnotation(new IndexAttribute()));

Practical Example:

Here is a more realistic example. It adds a unique index on multiple properties: User.FirstName and User.LastName, with an index name "IX_FirstNameLastName"

modelBuilder 
    .Entity<User>() 
    .Property(t => t.FirstName) 
    .IsRequired()
    .HasMaxLength(60)

try the following as there will be no varchar conversion

SELECT Subject, CAST(DeliveryDate AS DATE)
from Email_Administration 
where MerchantId =@ MerchantID

//you can use the ? operator instead of if

ddlCustomerNumber.SelectedValue = ddlType.Items.FindByValue(GetCustomerNumberCookie().ToString()) != null ? GetCustomerNumberCookie().ToString() : "0";

Try to change the rpc_address to point to the node's IP instead of 0.0.0.0 and specify the IP while connecting to the cqlsh, as if the IP is 10.0.2.64 and the rpc_port left to the default value 9160 then the following should work:

cqlsh 10.0.2.64 9160 

OR

cqlsh 10.0.2.64

Also make sure that start_rpc is set to true in /etc/cassandra/cassandra.yaml configuration file.

Although it is not recommended, but if you really want to let your web application access a folder outside its deployment directory. You need to add following permission in java.policy file (path is as in the reply of Petey B)

permission java.io.FilePermission "your folder path", "write"

In your case it would be

permission java.io.FilePermission "S:/PDSPopulatingProgram/-", "write"

Here /- means any files or sub-folders inside this folder.

Warning: But by doing this, you are inviting some security risk.

Here's another issue I have with symbolicatecrash – it won't work with Apps that have spaces in their bundle (i.e. 'Test App.app'). Note I don't think you can have spaces in their name when submitting so you should remove these anyway, but if you already have crashes that need analysing, patch symbolicatecrash (4.3 GM) as such:
