If I get your question correctly, you could do something like this.

>>> import matplotlib.pyplot as plt
>>> testList =[(0, 6.0705199999997801e-08), (1, 2.1015700100300739e-08), 
 (2, 7.6280656623374823e-09), (3, 5.7348209304555086e-09), 
 (4, 3.6812203579604238e-09), (5, 4.1572516753310418e-09)]
>>> from math import log
>>> testList2 = [(elem1, log(elem2)) for elem1, elem2 in testList]
>>> testList2
[(0, -16.617236475334405), (1, -17.67799605473062), (2, -18.691431541177973), (3, -18.9767093108359), (4, -19.420021520728017), (5, -19.298411635970396)]
>>> zip(*testList2)
[(0, 1, 2, 3, 4, 5), (-16.617236475334405, -17.67799605473062, -18.691431541177973, -18.9767093108359, -19.420021520728017, -19.298411635970396)]
>>> plt.scatter(*zip(*testList2))
>>> plt.show()

which would give you something like

Or as a line plot,

>>> plt.plot(*zip(*testList2))
>>> plt.show()

EDIT - If you want to add a title and labels for the axis, you could do something like

>>> plt.scatter(*zip(*testList2))
>>> plt.title('Random Figure')
>>> plt.xlabel('X-Axis')
>>> plt.ylabel('Y-Axis')
>>> plt.show()

which would give you

-webkit-appearance: none;

and add your own style

A proper benchmark or how the number may lie

Following the argument about Math.ceil(value/10d) and (value+9)/10 I ended up coding a proper non-dead code, non-interpret mode benchmark. I've been telling that writing micro benchmark is not an easy task. The code below illustrates this:

00:21:40.109 starting up....
00:21:40.140 doubleCeil: 19444599
00:21:40.140 integerCeil: 19444599
00:21:40.140 warming up...
00:21:44.375 warmup doubleCeil: 194445990000
00:21:44.625 warmup integerCeil: 194445990000
00:22:27.437 exec doubleCeil: 1944459900000, elapsed: 42.806s
00:22:29.796 exec integerCeil: 1944459900000, elapsed: 2.363s

The benchmark is in Java since I know well how Hotspot optimizes and ensures it's a fair result. With such results, no statistics, noise or anything can taint it.

Integer ceil is insanely much faster.

The code

package t1;

import java.math.BigDecimal;

import java.util.Random;

public class Div {
    static int[] vals;

    static long doubleCeil(){
        int[] v= vals;
        long sum = 0;
        for (int i=0;i<v.length;i++){
            int value = v[i];
            sum+=Math.ceil(value/10d);
        }
        return sum;
    }

    static long integerCeil(){      
        int[] v= vals;
        long sum = 0;
        for (int i=0;i<v.length;i++){
            int value = v[i];
            sum+=(value+9)/10;
        }
        return sum;     
    }

    public static void main(String[] args) {
        vals = new  int[7000];
        Random r= new Random(77);
        for (int i = 0; i < vals.length; i++) {
            vals[i] = r.nextInt(55555);
        }
        log("starting up....");

        log("doubleCeil: %d", doubleCeil());
        log("integerCeil: %d", integerCeil());
        log("warming up...");       

        final int warmupCount = (int) 1e4;
        log("warmup doubleCeil: %d", execDoubleCeil(warmupCount));
        log("warmup integerCeil: %d", execIntegerCeil(warmupCount));

        final int execCount = (int) 1e5;

        {       
        long time = System.nanoTime();
        long s = execDoubleCeil(execCount);
        long elapsed = System.nanoTime() - time;
        log("exec doubleCeil: %d, elapsed: %.3fs",  s, BigDecimal.valueOf(elapsed, 9));
        }

        {
        long time = System.nanoTime();
        long s = execIntegerCeil(execCount);
        long elapsed = System.nanoTime() - time;
        log("exec integerCeil: %d, elapsed: %.3fs",  s, BigDecimal.valueOf(elapsed, 9));            
        }
    }

    static long execDoubleCeil(int count){
        long sum = 0;
        for(int i=0;i<count;i++){
            sum+=doubleCeil();
        }
        return sum;
    }


    static long execIntegerCeil(int count){
        long sum = 0;
        for(int i=0;i<count;i++){
            sum+=integerCeil();
        }
        return sum;
    }

    static void log(String msg, Object... params){
        String s = params.length>0?String.format(msg, params):msg;
        System.out.printf("%tH:%<tM:%<tS.%<tL %s%n", new Long(System.currentTimeMillis()), s);
    }   
}

Consider

// myHeader.h
#include <sstream>
using namespace std;


// someoneElses.cpp/h
#include "myHeader.h"

class stringstream {  // Uh oh
};

Note that this is a simple example. If you have files with 20 includes and other imports, you'll have a ton of dependencies to go through to figure out the problem. The worse thing about it is that you can get unrelated errors in other modules depending on the definitions that conflict.

It's not horrible, but you'll save yourself headaches by not using it in header files or the global namespace. It's probably all right to do it in very limited scopes, but I've never had a problem typing the extra five characters to clarify where my functions are coming from.

I tried to solve this issue.

My answer is here.

"DynamicHeader" - http://dynamicheader.codeplex.com/, https://nuget.org/packages/DynamicHeader

For example, _Layout.cshtml is:

<head>
@Html.DynamicHeader()
</head>
...

And, you can register .js and .css files to "DynamicHeader" anywhere you want.

For example, the code block in AnotherPartial.cshtml is:

@{
  DynamicHeader.AddSyleSheet("~/Content/themes/base/AnotherPartial.css");
  DynamicHeader.AddScript("~/some/myscript.js");
}

Result HTML output for this sample is:

<html>
  <link href="/myapp/Content/themes/base/AnotherPartial.css" .../>
  <script src="/myapp/some/myscript.js" ...></script>
</html>
...

If you really need it...

html { overflow-y: hidden; }

For visualization our group had some success with prefuse. We extended it to handle architectural floorplates and bubble diagraming, and it didn't complain too much. They have a new Flex toolkit out too called Flare that uses a very similar API.

UPDATE: I'd have to agree with the comment, we ended up writing a lot of custom functionality/working around prefuse limitations. I can't say that starting from scratch would have been better though as we were able to demonstrate progress from day 1 by using prefuse. On the other hand if we were doing a second implementation of the same stuff, I might skip prefuse since we'd understand the requirements a lot better.

The issue with

List<String> list = new LinkedList();

is that on the left hand side, you are using the generic type List<String> where on the right side you are using the raw type LinkedList. Raw types in Java effectively only exist for compatibility with pre-generics code and should never be used in new code unless you absolutely have to.

Now, if Java had generics from the beginning and didn't have types, such as LinkedList, that were originally created before it had generics, it probably could have made it so that the constructor for a generic type automatically infers its type parameters from the left-hand side of the assignment if possible. But it didn't, and it must treat raw types and generic types differently for backwards compatibility. That leaves them needing to make a slightly different, but equally convenient, way of declaring a new instance of a generic object without having to repeat its type parameters... the diamond operator.

As far as your original example of List<String> list = new LinkedList(), the compiler generates a warning for that assignment because it must. Consider this:

List<String> strings = ... // some list that contains some strings

// Totally legal since you used the raw type and lost all type checking!
List<Integer> integers = new LinkedList(strings);

Generics exist to provide compile-time protection against doing the wrong thing. In the above example, using the raw type means you don't get this protection and will get an error at runtime. This is why you should not use raw types.

// Not legal since the right side is actually generic!
List<Integer> integers = new LinkedList<>(strings);

The diamond operator, however, allows the right hand side of the assignment to be defined as a true generic instance with the same type parameters as the left side... without having to type those parameters again. It allows you to keep the safety of generics with almost the same effort as using the raw type.

I think the key thing to understand is that raw types (with no <>) cannot be treated the same as generic types. When you declare a raw type, you get none of the benefits and type checking of generics. You also have to keep in mind that generics are a general purpose part of the Java language... they don't just apply to the no-arg constructors of Collections!

First few lines: man head.

Append lines: use the >> operator (?) in Bash:

echo 'This goes at the end of the file' >> file

Be very careful: NULL is a macro used mainly for pointers. The standard way of terminating a string is:

char *buffer;
...
buffer[end_position] = '\0';

This (below) works also but it is not a big difference between assigning an integer value to a int/short/long array and assigning a character value. This is why the first version is preferred and personally I like it better.

buffer[end_position] = 0; 

Cudos accepted answer is great. However, the Draggable module also has a "drag" event that tells you the position while your dragging. So, in addition to the 'start' and 'stop' you could add the following event within your Draggable object:

    // Drag current position of dragged image.
    drag: function(event, ui) {

        // Show the current dragged position of image
        var currentPos = $(this).position();
        $("div#xpos").text("CURRENT: \nLeft: " + currentPos.left + "\nTop: " + currentPos.top);

    }

The thing about collations is that although the database has its own collation, every table, and every column can have its own collation. If not specified it takes the default of its parent object, but can be different.

When you change collation of the database, it will be the new default for all new tables and columns, but it doesn't change the collation of existing objects inside the database. You have to go and change manually the collation of every table and column.

Luckily there are scripts available on the internet that can do the job. I am not going to recommend any as I haven't tried them but here are few links:

http://www.codeproject.com/Articles/302405/The-Easy-way-of-changing-Collation-of-all-Database

Update Collation of all fields in database on the fly

http://www.sqlservercentral.com/Forums/Topic820675-146-1.aspx

If you need to have different collation on two objects or can't change collations - you can still JOIN between them using COLLATE command, and choosing the collation you want for join.

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE Latin1_General_CI_AS 

or using default database collation:

SELECT * FROM A JOIN B ON A.Text = B.Text COLLATE DATABASE_DEFAULT

Using JSON.stringify(data);:

$.ajax({
    url: ...
    success:function(data){
        JSON.stringify(data); //to string
        alert(data.you_value); //to view you pop up
    }
});

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

The $.fn.equals(...) solution is probably the cleanest and most elegant one.

I have tried something quick and dirty like this:

JSON.stringify(a) == JSON.stringify(b)

It is probably expensive, but the comfortable thing is that it is implicitly recursive, while the elegant solution is not.

Just my 2 cents.

By Changing The DbContext As Below;

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>();
        modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>();
    }

Just adding in OnModelCreating method call to base.OnModelCreating(modelBuilder); and it becomes fine. I am using EF6.

Angularjs Dependency Injection framework is responsible for injecting the dependancies of you app module to your controllers. This is possible through its injector.

You need to first identify the ng-app and get the associated injector. The below query works to find your ng-app in the DOM and retrieve the injector.

angular.element('*[ng-app]').injector()

In chrome, however, you can point to target ng-app as shown below. and use the $0 hack and issue angular.element($0).injector()

Once you have the injector, get any dependency injected service as below

injector = angular.element($0).injector();
injector.get('$mdToast');

There are many different ways to convert a datetime to a string. Here is one way:

SELECT convert(varchar(25), getdate(), 121)  – yyyy-mm-dd hh:mm:ss.mmm

See Demo

Here is a website that has a list of all of the conversions:

How to Format datetime & date in SQL Server

Use a grep analog to find the strings oldnamespace and Jenine inside the files in your whole project folder. Then you'd know what step to do next.

As a one liner:

ImageIO.write(Scalr.resize(ImageIO.read(...), 150));

Just use generator expressions:

blahblah = (l.rstrip() for l in open(filename))
for x in blahblah:
    print x

Also I want to advise you against reading whole file in memory -- looping over generators is much more efficient on big datasets.

For getting the element in react you need to use ref and inside the function you can use the ReactDOM.findDOMNode method.

But what I like to do more is to call the ref right inside the event

<input type="text" ref={ref => this.myTextInput = ref} />

This is some good link to help you figure out.

You can specify the style of the plotted line when calling df.plot:

df.plot(x='col_name_1', y='col_name_2', style='o')

The style argument can also be a dict or list, e.g.:

import numpy as np
import pandas as pd

d = {'one' : np.random.rand(10),
     'two' : np.random.rand(10)}

df = pd.DataFrame(d)

df.plot(style=['o','rx'])

All the accepted style formats are listed in the documentation of matplotlib.pyplot.plot.

You cannot directly change a form's validity. If all the descendant inputs are valid, the form is valid, if not, then it is not.

What you should do is to set the validity of the input element. Like so;

addItem.capabilities.$setValidity("youAreFat", false);

Now the input (and so the form) is invalid. You can also see which error causes invalidation.

addItem.capabilities.errors.youAreFat == true;

The java.util.logging.Level documentation does a good job of defining when to use a log level and the target audience of that log level.

Most of the confusion with java.util.logging is in the tracing methods. It should be in the class level documentation but instead the Level.FINE field provides a good overview:

FINE is a message level providing tracing information. All of FINE, FINER, and FINEST are intended for relatively detailed tracing. The exact meaning of the three levels will vary between subsystems, but in general, FINEST should be used for the most voluminous detailed output, FINER for somewhat less detailed output, and FINE for the lowest volume (and most important) messages. In general the FINE level should be used for information that will be broadly interesting to developers who do not have a specialized interest in the specific subsystem. FINE messages might include things like minor (recoverable) failures. Issues indicating potential performance problems are also worth logging as FINE.

One important thing to understand which is not mentioned in the level documentation is that call-site tracing information is logged at FINER.

• Logger#entering A LogRecord with message "ENTRY", log level FINER, ...
• Logger#throwing The logging is done using the FINER level...The LogRecord's message is set to "THROW"
• Logger#exiting A LogRecord with message "RETURN", log level FINER...

If you log a message as FINE you will be able to configure logging system to see the log output with or without tracing log records surrounding the log message. So use FINE only when tracing log records are not required as context to understand the log message.

FINER indicates a fairly detailed tracing message. By default logging calls for entering, returning, or throwing an exception are traced at this level.

In general, most use of FINER should be left to call of entering, exiting, and throwing. That will for the most part reserve FINER for call-site tracing when verbose logging is turned on. When swallowing an expected exception it makes sense to use FINER in some cases as the alternative to calling trace throwing method since the exception is not actually thrown. This makes it look like a trace when it isn't a throw or an actual error that would be logged at a higher level.

FINEST indicates a highly detailed tracing message.

Use FINEST when the tracing log message you are about to write requires context information about program control flow. You should also use FINEST for tracing messages that produce large amounts of output data.

CONFIG messages are intended to provide a variety of static configuration information, to assist in debugging problems that may be associated with particular configurations. For example, CONFIG message might include the CPU type, the graphics depth, the GUI look-and-feel, etc.

The CONFIG works well for assisting system admins with the items listed above.

Typically INFO messages will be written to the console or its equivalent. So the INFO level should only be used for reasonably significant messages that will make sense to end users and system administrators.

Examples of this are tracing program startup and shutdown.

In general WARNING messages should describe events that will be of interest to end users or system managers, or which indicate potential problems.

An example use case could be exceptions thrown from AutoCloseable.close implementations.

In general SEVERE messages should describe events that are of considerable importance and which will prevent normal program execution. They should be reasonably intelligible to end users and to system administrators.

For example, if you have transaction in your program where if any one of the steps fail then all of the steps voided then SEVERE would be appropriate to use as the log level.

print("My type is %s" % type(someObject)) # the type in python

or...

print("My type is %s" % type(someObject).__name__) # the object's type (the class you defined)

Convert the string to an InputStream and pass it to DocumentBuilder

final InputStream stream = new ByteArrayInputStream(string.getBytes(StandardCharsets.UTF_8));
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
builder.parse(stream);

EDIT
In response to bendin's comment regarding encoding, see shsteimer's answer to this question.

You can try this:

<form action="/home">_x000D_
  _x000D_
  <input type="submit" value="cancel">_x000D_
  _x000D_
  <input type="submit" value="login" formaction="/login">_x000D_
  <input type="submit" value="signup" formaction="/signup">_x000D_
  _x000D_
</form>

First method you can try this

$department->department_name = $request->department_name;
$department->status = $request->status;
$department->save();

Another way to insert records into the database with create function

$department = new Department;           
// Another Way to insert records
$department->create($request->all());

return redirect('admin/departments');

You need to set the filledby in Department model

namespace App;

use Illuminate\Database\Eloquent\Model;

class Department extends Model
{
    protected $fillable = ['department_name','status'];
} 

As of Rails 5, the rake commandline tool has been aliased as rails so now

rails db:reset instead of rake db:reset

will work just as well

SWIFT 5

With the latest release of Swift 3 we can get pretty descriptions of type names through the String initializer. Like, for example print(String(describing: type(of: object))). Where object can be an instance variable like array, a dictionary, an Int, a NSDate, an instance of a custom class, etc.

Here is my complete answer: Get class name of object as string in Swift

That question is looking for a way to getting the class name of an object as string but, also i proposed another way to getting the class name of a variable that isn't subclass of NSObject. Here it is:

class Utility{
    class func classNameAsString(obj: Any) -> String {
        //prints more readable results for dictionaries, arrays, Int, etc
        return String(describing: type(of: obj))
    }
}

I made a static function which takes as parameter an object of type Any and returns its class name as String :) .

I tested this function with some variables like:

    let diccionary: [String: CGFloat] = [:]
    let array: [Int] = []
    let numInt = 9
    let numFloat: CGFloat = 3.0
    let numDouble: Double = 1.0
    let classOne = ClassOne()
    let classTwo: ClassTwo? = ClassTwo()
    let now = NSDate()
    let lbl = UILabel()

and the output was:

• diccionary is of type Dictionary
• array is of type Array
• numInt is of type Int
• numFloat is of type CGFloat
• numDouble is of type Double
• classOne is of type: ClassOne
• classTwo is of type: ClassTwo
• now is of type: Date
• lbl is of type: UILabel

From CREATE FUNCTION:

When a parameter of the function has a default value, the keyword DEFAULT must be specified when the function is called to retrieve the default value. This behavior is different from using parameters with default values in stored procedures in which omitting the parameter also implies the default value.

So you need to do:

SELECT dbo.fCalculateEstimateDate(647,DEFAULT)

li + li {
    background-color: red;
}

I'm using @foreach when I send an entity that contains a list of entities ( for example to display 2 grids in 1 view )

For example if I'm sending as model the entity Foo that contains Foo1(List<Foo1>) and Foo2(List<Foo2>)

I can refer to the first List with:

@foreach (var item in Model.Foo.Foo1)
{
    @Html.DisplayFor(modelItem=> item.fooName)
}

Try this

select to_char(DATEFIELD,'MON') from YOUR_TABLE

eg.

select to_char(sysdate, 'MON') from dual

And yet another option: https://github.com/apptik/jus

• It is modular like Volley, but more extended and documentation is improving, supporting different HTTP stacks and converters out of the box
• It has a module to generate server API interface mappings like Retrofit
• It also has JavaRx support

And many other handy features like markers, transformers, etc.

So it turns out that if I add the Handler Mappings on the Website and Application level, everything works beautifully. I was only adding them on the server level, thus IIS did not know to map the asp pages to the IsapiModule.

So to resolve this issue, go to the website you want to add your application to, then double click on Handler Mappings. Click "Add Script Map" and enter in the following information:

RequestPath: *.asp
Executable: C:\Windows\System32\inetsrv\asp.dll
Name: Classic ASP (this can be anything you want it to be

Please check if you are disable error reporting somewhere in your code.

There was a place in my code where I have disabled it, so I added the debug code after it:

require_once("inc/req.php");   <-- Error reporting is disabled here

// overwrite it
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Very simple use of any

.dex file

Compiled Android application code file.

Android programs are compiled into .dex (Dalvik Executable) files, which are in turn zipped into a single .apk file on the device. .dex files can be created automatically by Android, by translating the compiled applications written in the Java programming language.

No, VBA does not have this functionality. You can use the technique of adding each item to a collection using the item as the key. Since a collection does not allow duplicate keys, the result is distinct values that you can copy to an array, if needed.

You may also want something more robust. See Distinct Values Function at http://www.cpearson.com/excel/distinctvalues.aspx

Distinct Values Function

A VBA Function that will return an array of the distinct values in a range or array of input values.

Excel has some manual methods, such as Advanced Filter, for getting a list of distinct items from an input range. The drawback of using such methods is that you must manually refresh the results when the input data changes. Moreover, these methods work only with ranges, not arrays of values, and, not being functions, cannot be called from worksheet cells or incorporated into array formulas. This page describes a VBA function called DistinctValues that accepts as input either a range or an array of data and returns as its result an array containing the distinct items from the input list. That is, the elements with all duplicates removed. The order of the input elements is preserved. The order of the elements in the output array is the same as the order in the input values. The function can be called from an array entered range on a worksheet (see this page for information about array formulas), or from in an array formula in a single worksheet cell, or from another VB function.

And if you'd like to extract the differences between the two strings, you can use String::Diff.

Do like jQuery does! (the essence)

function parseJSON(data) {
    return window.JSON && window.JSON.parse ? window.JSON.parse( data ) : (new Function("return " + data))(); 
}
// testing
obj = parseJSON('{"name":"John"}');
alert(obj.name);

This way you don't need any external library and it still works on old browsers.

Update:

I have added this link to my other answer how to use JWT authentication for ASP.NET Web API here for anyone interested in JWT.

We have managed to apply HMAC authentication to secure Web API, and it worked okay. HMAC authentication uses a secret key for each consumer which both consumer and server both know to hmac hash a message, HMAC256 should be used. Most of the cases, hashed password of the consumer is used as a secret key.

The message normally is built from data in the HTTP request, or even customized data which is added to HTTP header, the message might include:

1. Timestamp: time that request is sent (UTC or GMT)
2. HTTP verb: GET, POST, PUT, DELETE.
3. post data and query string,
4. URL

Under the hood, HMAC authentication would be:

Consumer sends a HTTP request to web server, after building the signature (output of hmac hash), the template of HTTP request:

User-Agent: {agent}   
Host: {host}   
Timestamp: {timestamp}
Authentication: {username}:{signature}

Example for GET request:

GET /webapi.hmac/api/values

User-Agent: Fiddler    
Host: localhost    
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

The message to hash to get signature:

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n

Example for POST request with query string (signature below is not correct, just an example)

POST /webapi.hmac/api/values?key2=value2

User-Agent: Fiddler    
Host: localhost    
Content-Type: application/x-www-form-urlencoded
Timestamp: Thursday, August 02, 2012 3:30:32 PM 
Authentication: cuongle:LohrhqqoDy6PhLrHAXi7dUVACyJZilQtlDzNbLqzXlw=

key1=value1&key3=value3

The message to hash to get signature

GET\n
Thursday, August 02, 2012 3:30:32 PM\n
/webapi.hmac/api/values\n
key1=value1&key2=value2&key3=value3

Please note that form data and query string should be in order, so the code on the server get query string and form data to build the correct message.

When HTTP request comes to the server, an authentication action filter is implemented to parse the request to get information: HTTP verb, timestamp, uri, form data and query string, then based on these to build signature (use hmac hash) with the secret key (hashed password) on the server.

The secret key is got from the database with the username on the request.

Then server code compares the signature on the request with the signature built; if equal, authentication is passed, otherwise, it failed.

The code to build signature:

private static string ComputeHash(string hashedPassword, string message)
{
    var key = Encoding.UTF8.GetBytes(hashedPassword.ToUpper());
    string hashString;

    using (var hmac = new HMACSHA256(key))
    {
        var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(message));
        hashString = Convert.ToBase64String(hash);
    }

    return hashString;
}

So, how to prevent replay attack?

Add constraint for the timestamp, something like:

servertime - X minutes|seconds  <= timestamp <= servertime + X minutes|seconds 

(servertime: time of request coming to server)

And, cache the signature of the request in memory (use MemoryCache, should keep in the limit of time). If the next request comes with the same signature with the previous request, it will be rejected.

The demo code is put as here: https://github.com/cuongle/Hmac.WebApi

In the POSIX standard, which /bin/sh is supposed to respect, the command is . (a single dot), not source. The source command is a csh-ism that has been pulled into bash.

Try

. $env_name/bin/activate

Or if you must have non-POSIX bash-isms in your code, use #!/bin/bash.

str = str[0...-n]

How about using direct axios API?

axios({
  method: 'post',
  url: baseUrl + 'applications/' + appName + '/dataexport/plantypes' + plan,
  headers: {}, 
  data: {
    foo: 'bar', // This is the body part
  }
});

What they both have in common is that they both use a partition to differentiate between the sorted part of the array and the unsorted.

The difference is, that with selection sort you are guaranteed that sorted part of the array won't change when adding elements to the sorted partition.

The reason being, because selection searches for the minimum of the unsorted set and adds it right after the last element of the sorted set, thereby increasing the sorted set by 1.

Insertion on the other hand, only just cares about the next element that is encountered, which is the first element in the unsorted part of the array. It will take this element and simply fit it into its proper place in the sorted set.

Insertion sort will typically always be a better candidate for arrays that are only partially sorted because you are wasting operations to find the minimum.

Conclusion:

Selection sort incrementally adds an element to the end by finding the minimum element in the unsorted section.

Insertion sort propagates the first element found in the unsorted section into anywhere in the sorted section.

The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):

public static File getResourceAsFile(String resourcePath) {
    try {
        InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
        if (in == null) {
            return null;
        }

        File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
        tempFile.deleteOnExit();

        try (FileOutputStream out = new FileOutputStream(tempFile)) {
            //copy stream
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = in.read(buffer)) != -1) {
                out.write(buffer, 0, bytesRead);
            }
        }
        return tempFile;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

It has to do with the general workflow of Git. You're unlikely to be able to push directly to the main project's repository. I'm not sure if GitHub project's repository support branch-based access control, as you wouldn't want to grant anyone the permission to push to the master branch for example.

The general pattern is as follows:

• Fork the original project's repository to have your own GitHub copy, to which you'll then be allowed to push changes.
• Clone your GitHub repository onto your local machine
• Optionally, add the original repository as an additional remote repository on your local repository. You'll then be able to fetch changes published in that repository directly.
• Make your modifications and your own commits locally.
• Push your changes to your GitHub repository (as you generally won't have the write permissions on the project's repository directly).
• Contact the project's maintainers and ask them to fetch your changes and review/merge, and let them push back to the project's repository (if you and them want to).

Without this, it's quite unusual for public projects to let anyone push their own commits directly.

I've submitted a pull request (available in Ansible 2.2+) that will make this kinds of situations easier by adding jmespath query support on Ansible. In your case it would work like:

- debug: msg="{{ addresses | json_query(\"private_man[?type=='fixed'].addr\") }}"

would return:

ok: [localhost] => {
    "msg": [
        "172.16.1.100"
    ]
}

The answer to your problem is easy: replace the current Fragment with the new Fragment and push transaction onto the backstack. This preserves back button behaviour...

Creating a new Activity really defeats the whole purpose to use fragments anyway...very counter productive.

@Override
public void onClick(View v) {
    // Create new fragment and transaction
    Fragment newFragment = new chartsFragment(); 
    // consider using Java coding conventions (upper first char class names!!!)
    FragmentTransaction transaction = getFragmentManager().beginTransaction();

    // Replace whatever is in the fragment_container view with this fragment,
    // and add the transaction to the back stack
    transaction.replace(R.id.fragment_container, newFragment);
    transaction.addToBackStack(null);

    // Commit the transaction
    transaction.commit(); 
}

As explained in the different asnwers already, sys.argv contains the command line arguments that called your Python script.

However, Python comes with libraries that help you parse command line arguments very easily. Namely, the new standard argparse. Using argparse would spare you the need to write a lot of boilerplate code.

Yes, there is: https://github.com/robinrowe/libunistd

Clone the repository and add path\to\libunistd\unistd to the INCLUDE environment variable.

You can use itertools.chain():

import itertools
list2d = [[1,2,3], [4,5,6], [7], [8,9]]
merged = list(itertools.chain(*list2d))

Or you can use itertools.chain.from_iterable() which doesn't require unpacking the list with the * operator:

import itertools
list2d = [[1,2,3], [4,5,6], [7], [8,9]]
merged = list(itertools.chain.from_iterable(list2d))

JavaScript

document.addEventListener('readystatechange', event => { 

    // When HTML/DOM elements are ready:
    if (event.target.readyState === "interactive") {   //does same as:  ..addEventListener("DOMContentLoaded"..
        alert("hi 1");
    }

    // When window loaded ( external resources are loaded too- `css`,`src`, etc...) 
    if (event.target.readyState === "complete") {
        alert("hi 2");
    }
});

same for jQuery:

$(document).ready(function() {   //same as: $(function() { 
     alert("hi 1");
});

$(window).load(function() {
     alert("hi 2");
});

NOTE: - Don't use the below markup ( because it overwrites other same-kind declarations ) :

document.onreadystatechange = ...

The quick answer:

f=open('filename')
lines=f.readlines()
print lines[25]
print lines[29]

or:

lines=[25, 29]
i=0
f=open('filename')
for line in f:
    if i in lines:
        print i
    i+=1

There is a more elegant solution for extracting many lines: linecache (courtesy of "python: how to jump to a particular line in a huge text file?", a previous stackoverflow.com question).

Quoting the python documentation linked above:

>>> import linecache
>>> linecache.getline('/etc/passwd', 4)
'sys:x:3:3:sys:/dev:/bin/sh\n'

Change the 4 to your desired line number, and you're on. Note that 4 would bring the fifth line as the count is zero-based.

If the file might be very large, and cause problems when read into memory, it might be a good idea to take @Alok's advice and use enumerate().

To Conclude:

• Use fileobject.readlines() or for line in fileobject as a quick solution for small files.
• Use linecache for a more elegant solution, which will be quite fast for reading many files, possible repeatedly.
• Take @Alok's advice and use enumerate() for files which could be very large, and won't fit into memory. Note that using this method might slow because the file is read sequentially.

Be careful with this. There are a number of different 'contexts' within an HTML document: Inside an element, quoted attribute value, unquoted attribute value, URL attribute, javascript, CSS, etc... You'll need to use a different encoding method for each of these to prevent Cross-Site Scripting (XSS). Check the OWASP XSS Prevention Cheat Sheet for details on each of these contexts. You can find escaping methods for each of these contexts in the OWASP ESAPI library -- https://github.com/ESAPI/esapi-java-legacy.

RuntimeHelpers.GetHashCode() may help (MSDN).

Try just parent.myfunction()

In my NodeJS example, I have an url "localhost:8080/Lists/list1.html?x1=y" that I want to traverse and acquire values.

In order to work with $location.search() to get x1=y, I have done a few things

1. script source to angular-route.js
2. Inject 'ngRoute' into your app module's dependencies
3. Config your locationProvider
4. Add the base tag for $location (if you don't, your search().x1 would return nothing or undefined. Or if the base tag has the wrong info, your browser would not be able to find your files inside script src that your .html needs. Always open page's view source to test your file locations!)
5. invoke the location service (search())

my list1.js has

    var app = angular.module('NGApp', ['ngRoute']);  //dependencies : ngRoute
    app.config(function ($locationProvider) { //config your locationProvider
         $locationProvider.html5Mode(true).hashPrefix('');
    });

    app.controller('NGCtrl', function ($scope, datasvc, $location) {// inject your location service
        //var val = window.location.href.toString().split('=')[1];
        var val = $location.search().x1;    alert(val);
        $scope.xout = function () {
           datasvc.out(val)
           .then(function (data) {
              $scope.x1 = val;
              $scope.allMyStuffs = data.all;
           });
        };
        $scope.xout();
    });

and my list1.html has

<head>
    <base href=".">
    </head>
<body ng-controller="NGCtrl">
<div>A<input ng-model="x1"/><br/><textarea ng-model="allMyStuffs"/></div>

As my purpose is to get an empty version of the test database to import data from an external previous current active source (Access database) once all is fine tuned. I found that using DBCC CloneDatabase with Verify_CloneDB option fits perfectly.

add this to your form:

<form  id="regform" action="insert.php" method="post">

add this to your function:

<script>
    function myFunction() {
        var pass1 = document.getElementById("pass1").value;
        var pass2 = document.getElementById("pass2").value;
        if (pass1 != pass2) {
            //alert("Passwords Do not match");
            document.getElementById("pass1").style.borderColor = "#E34234";
            document.getElementById("pass2").style.borderColor = "#E34234";
        }
        else {
            alert("Passwords Match!!!");
            document.getElementById("regForm").submit();
        }
    }
</script>

Had the same issue. Turns out I was using " instead of '.

use @import url('within single quotes'); like this

not @import url("within double quotes"); like this

After having tried some things on this page without success I had a look in the page-source and remarked that all quotes in the serialized string have been replaced by html-entities. Decoding these entities helps avoiding much headache:

$myVar = html_entity_decode($myVar);

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

Alternatively, you could use the jQuery 1.2 inArray function, which should work across browsers:

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

<p> tags have built in padding and margin. You could create a CSS selector combined with some javascript for instances when your <p> is empty. Probably overkill, but it should do what you need it to do.

CSS example: .NoPaddingOrMargin {padding: 0px; margin:0px}

See the mysql manual, Unicode Character Sets section:

For any Unicode character set, operations performed using the _general_ci collation are faster than those for the _unicode_ci collation. For example, comparisons for the utf8_general_ci collation are faster, but slightly less correct, than comparisons for utf8_unicode_ci. The reason for this is that utf8_unicode_ci supports mappings such as expansions; that is, when one character compares as equal to combinations of other characters. For example, in German and some other languages “ß” is equal to “ss”. utf8_unicode_ci also supports contractions and ignorable characters. utf8_general_ci is a legacy collation that does not support expansions, contractions, or ignorable characters. It can make only one-to-one comparisons between characters.

So to summarize, utf_general_ci uses a smaller and less correct (according to the standard) set of comparisons than utf_unicode_ci which should implement the entire standard. The general_ci set will be faster because there is less computation to do.

The following code worked for me:

echo userInput

You can loop over each row of the DataTable and check the value.

I'm a big fan of using a foreach loop when using IEnumerables. Makes it very simple and clean to look at or process each row

DataTable dtPs = // ... initialize your DataTable
foreach (DataRow dr in dtPs.Rows)
{
    if (dr["item_manuf_id"].ToString() == "some value")
    {
        // do your deed
    }
}

Alternatively you can use a PrimaryKey for your DataTable. This helps in various ways, but you often need to define one before you can use it.

An example of using one if at http://msdn.microsoft.com/en-us/library/z24kefs8(v=vs.80).aspx

DataTable workTable = new DataTable("Customers");

// set constraints on the primary key
DataColumn workCol = workTable.Columns.Add("CustID", typeof(Int32));
workCol.AllowDBNull = false;
workCol.Unique = true;

workTable.Columns.Add("CustLName", typeof(String));
workTable.Columns.Add("CustFName", typeof(String));
workTable.Columns.Add("Purchases", typeof(Double));

// set primary key
workTable.PrimaryKey = new DataColumn[] { workTable.Columns["CustID"] };

Once you have a primary key defined and data populated, you can use the Find(...) method to get the rows that match your primary key.

Take a look at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx

DataRow drFound = dtPs.Rows.Find("some value");
if (drFound["item_manuf_id"].ToString() == "some value")
{
    // do your deed
}

Finally, you can use the Select() method to find data within a DataTable also found at at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx.

String sExpression = "item_manuf_id == 'some value'";
DataRow[] drFound;
drFound = dtPs.Select(sExpression);

foreach (DataRow dr in drFound)
{
    // do you deed. Each record here was already found to match your criteria
}

Had the same problem yesterday. Now, after signing to the developer portal, for every invalid provisioning profile have a button "Renew". After renewing and downloading updated provisioning profile all seems to work as expected, so problem is definitely solved :)

Update: you may have to contact Apple to get a "Renew"-button, or they removed it -- and the solution is to just download it and add it to the keychain, no need to renew.

I saw the above result and query will work fine if you need to check single column value which are duplicate. For example email.

But if you need to check with more columns and would like to check the combination of the result so this query will work fine:

SELECT COUNT(CONCAT(name,email)) AS tot,
       name,
       email
FROM users
GROUP BY CONCAT(name,email)
HAVING tot>1 (This query will SHOW the USER list which ARE greater THAN 1
              AND also COUNT)

For deduplicate / dedupe / remove duplication / remove repeated rows / ??? ?? / ??? ?? ????, there are multiple ways.

1. If duplicated rows are exact the same, use group by

   create table TABLE_NAME_DEDUP
   as select column1, column2, ... (all column names) from TABLE_NAME group by column1, column2, -- all column names

Then TABLE_NAME_DEDUP is the deduplicated table.

For example,

create table test (t1 varchar(5), t2 varchar(5));
insert into test  values ('12345', 'ssdlh');
insert into test  values ('12345', 'ssdlh');
create table test_dedup as
select * from test 
group by t1, t2;
-----optional
--remove original table and rename dedup table to previous table
--this is not recommend in dev or qa. DROP table test; Alter table test_dedup rename to test;

2. You have a rowid, the rowid has duplication but other columns are different Records partial same, this may happened in a transactional system while update a row, and the rows failed to update will have nulls. You want to remove the duplication

   create table test_dedup as select column1, column2, ... (all column names) from ( select * , row_number() over (partition by rowid order by column1, column2, ... (all column names except rowid) ) as cn from test ) where cn =1

This is using the feature that when you use order by, the null value will be ordered behind the non-null value.

create table test (rowid_ varchar(5), t1 varchar(5), t2 varchar(5));
insert into test  values ('12345', 'ssdlh', null);
insert into test  values ('12345', 'ssdlh', 'lhbzj');
create table test_dedup as
select rowid_, t1, t2 from
(select *
  , row_number() over (partition by rowid_ order by t1, t2) as cn
  from  test)
 where cn =1
 ;

-----optional
--remove original table and rename dedup table to previous table
--this is not recommend in dev or qa. DROP table test; Alter table test_dedup rename to test;

var alphabets = Enumerable.Range('A', 26).Select((num) => ((char)num).ToString()).ToList();

Swift 2.0

extension Dictionary {

    mutating func unionInPlace(dictionary: Dictionary) {
        dictionary.forEach { self.updateValue($1, forKey: $0) }
    }

    func union(var dictionary: Dictionary) -> Dictionary {
        dictionary.unionInPlace(self)
        return dictionary
    }
}

This might be because you are using two method for inserting data into database and this cause the site to slow down.

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email).save()  <==== 
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')

In above function, the error is where arrow is pointing. The correct implementation is below:

def add_subscriber(request, email=None):
    if request.method == 'POST':
        email = request.POST['email_field']
        e = Subscriber.objects.create(email=email)
        return HttpResponseRedirect('/')
    else:
        return HttpResponseRedirect('/')

dynamic_cast can determine if the type contains the target type anywhere in the inheritance hierarchy (yes, it's a little-known feature that if B inherits from A and C, it can turn an A* directly into a C*). typeid() can determine the exact type of the object. However, these should both be used extremely sparingly. As has been mentioned already, you should always be avoiding dynamic type identification, because it indicates a design flaw. (also, if you know the object is for sure of the target type, you can do a downcast with a static_cast. Boost offers a polymorphic_downcast that will do a downcast with dynamic_cast and assert in debug mode, and in release mode it will just use a static_cast).

I tried following format, working fine

*/5 * * * * wget --quiet -O /dev/null http://localhost/cron.php

{} defines the contents of the array, in this case it is empty. These would both have an array of three Strings

String[] array = {"element1","element2","element3"};
String[] array = new String[] {"element1","element2","element3"};

while [] on the expression side (right side of =) of a statement defines the size of an intended array, e.g. this would have an array of 10 locations to place Strings

String[] array = new String[10];

...But...

String array = new String[10]{};  //The line you mentioned above

Was wrong because you are defining an array of length 10 ([10]), then defining an array of length 0 ({}), and trying to set them to the same array reference (array) in one statement. Both cannot be set.

Additionally

The array should be defined as an array of a given type at the start of the statement like String[] array. String array = /* array value*/ is saying, set an array value to a String, not to an array of Strings.

There is a nice GUI way to do this. Press CTRL+SHIFT+G ( or View-CSM in menu) and here you have a lot of options. With (...) you can do almost anything you want. After things be done, type your commit message into input box and press CTRL+ENTER. Pretty easy. If you have remote repo - you'll see a little spinner mark in bottom left corner near repo name. Press it and sync to remote easily.
But in order to do all of this you must have repo to be initialized in your working directory before (git init from terminal).

I found this to work very well!

function findRoot() { 
    return(substr($_SERVER["SCRIPT_FILENAME"], 0, (stripos($_SERVER["SCRIPT_FILENAME"], $_SERVER["SCRIPT_NAME"])+1)));
}

Use:

<?php

function findRoot() {
    return(substr($_SERVER["SCRIPT_FILENAME"], 0, (stripos($_SERVER["SCRIPT_FILENAME"], $_SERVER["SCRIPT_NAME"])+1)));
}

include(findRoot() . 'Post.php');
$posts = getPosts(findRoot() . 'posts_content');

include(findRoot() . 'includes/head.php');

for ($i=(sizeof($posts)-1); 0 <= $i; $i--) {
    $posts[$i]->displayArticle();
}

include(findRoot() . 'includes/footer.php');

?>

Do what Google is doing. Create a PHP file that sets the cookie on all 3 domains. Then on the domain where the theme is going to set, create a HTML file that would load the PHP file that sets cookie on the other 2 domains. Example:

<html>
   <head></head>
   <body>
      <p>Please wait.....</p>
      <img src="http://domain2.com/setcookie.php?theme=whateveryourthemehere" />
      <img src="http://domain3.com/setcookie.php?theme=whateveryourthemehere" />
   </body>
</html>

Then add an onload callback on body tag. The document will only load when the images completely load that is when cookies are set on the other 2 domains. Onload Callback :

<head>
   <script>
   function loadComplete(){
      window.location="http://domain1.com";//URL of domain1
   }
   </script>
</head>
<body onload="loadComplete()">

setcookie.php

We set the cookies on the other domains using a PHP file like this :

<?php
if(isset($_GET['theme'])){
   setcookie("theme", $_GET['theme'], time()+3600);
}
?>

Now cookies are set on the three domains.

well, there are many ways to do this in javascript just like other says. I don't think there's a way to do it in react. here's what I would do:

in a js file:

module.exports = {
    small_square: 's',
    large_square: 'q'
}

in your react file:

'use strict';

var Constant = require('constants');
....
var something = Constant.small_square;

something for you to consider, hope this helps

echo "12|23|11" | awk '{split($0,a,"|"); print a[3] a[2] a[1]}'

i dont know if there is a function but this would do the job in case there is no exsiting one:

String s = "here are a bunch of words";

final StringBuilder result = new StringBuilder(s.length());
String[] words = s.split("\\s");
for(int i=0,l=words.length;i<l;++i) {
  if(i>0) result.append(" ");      
  result.append(Character.toUpperCase(words[i].charAt(0)))
        .append(words[i].substring(1));

}

Type the kill -l command on your shell

you will found that at 9th number [ 9) SIGKILL ], so one can use either kill -9 or kill -SIGKILL

SIGKILL is sure kill signal, It can not be dis-positioned, ignore or handle. It always work with its default behaviour, which is to kill the process.

MyViewClass *myViewObject = [[[NSBundle mainBundle] loadNibNamed:@"MyViewClassNib" owner:self options:nil] objectAtIndex:0]

I'm using this to initialise the reusable custom views I have.

Note that you can use "firstObject" at the end there, it's a little cleaner. "firstObject" is a handy method for NSArray and NSMutableArray.

Here's a typical example, of loading a xib to use as a table header. In your file YourClass.m

- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
    return [[NSBundle mainBundle] loadNibNamed:@"TopArea" owner:self options:nil].firstObject;
}

Normally, in the TopArea.xib, you would click on File Owner and set the file owner to YourClass. Then actually in YourClass.h you would have IBOutlet properties. In TopArea.xib, you can drag controls to those outlets.

Don't forget that in TopArea.xib, you may have to click on the View itself and drag that to some outlet, so you have control of it, if necessary. (A very worthwhile tip is that when you are doing this for table cell rows, you absolutely have to do that - you have to connect the view itself to the relevant property in your code.)

You need a dict:

my_dict = {'cheese': 'cake'}

Example code (from the docs):

>>> a = dict(one=1, two=2, three=3)
>>> b = {'one': 1, 'two': 2, 'three': 3}
>>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3]))
>>> d = dict([('two', 2), ('one', 1), ('three', 3)])
>>> e = dict({'three': 3, 'one': 1, 'two': 2})
>>> a == b == c == d == e
True

You can read more about dictionaries here.

Try this:

SELECT *
FROM emptable 
WHERE empid IN (
    SELECT sal,row_number () ( OVER partition by sal order by sal desc) RN
    FROM emptable
    WHERE RN=2)

I prefer to use BINARY(32) since it's the optimized way!

You can place in that 32 hex digits from (00 to FF).

Therefore BINARY(32)!

You can use the built-in forEach function for arrays.

Like this:

//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
    element.product_desc = element.product_desc.substring(0,10);
});

Your version wasn't wrong though. It should look more like this:

for(let i=0; i<data.products.length; i++){
    console.log(data.products[i].product_desc); //use i instead of 0
}

Here is a class providing a cancel method for a delayed action

public class DelayedAction {

private Handler _handler;
private Runnable _runnable;

/**
 * Constructor
 * @param runnable The runnable
 * @param delay The delay (in milli sec) to wait before running the runnable
 */
public DelayedAction(Runnable runnable, long delay) {
    _handler = new Handler(Looper.getMainLooper());
    _runnable = runnable;
    _handler.postDelayed(_runnable, delay);
}

/**
 * Cancel a runnable
 */
public void cancel() {
    if ( _handler == null || _runnable == null ) {
        return;
    }
    _handler.removeCallbacks(_runnable);
}}

You can give the input element a font opacity of 0. This will hide the text field without hiding the 'Choose Files' button.

No javascript required, clear cross browser as far back as IE 9

E.g.,

input {color: rgba(0, 0, 0, 0);}

Here is from pandas docs on advanced indexing:

The section will explain exactly what you need! Turns out df.loc (as .ix has been deprecated -- as many have pointed out below) can be used for cool slicing/dicing of a dataframe. And. It can also be used to set things.

df.loc[selection criteria, columns I want] = value

So Bren's answer is saying 'find me all the places where df.A == 0, select column B and set it to np.nan'

Brando ZWZ provides some great answers to handling this situation.

Re: Same navbar on multiple pages Aug 21, 2018 10:13 AM|LINK

As far as I know, there are multiple solution.

For example:

The Entire code for navigation bar is in nav.html file (without any html or body tag, only the code for navigation bar).

Then we could directly load it from the jquery without writing a lot of codes.

Like this:

    <!--Navigation bar-->
    <div id="nav-placeholder">

    </div>

    <script>
    $(function(){
      $("#nav-placeholder").load("nav.html");
    });
    </script>
    <!--end of Navigation bar-->

Solution2:

You could use JavaScript code to generate the whole nav bar.

Like this:

Javascript code:

$(function () {
    var bar = '';
    bar += '<nav class="navbar navbar-default" role="navigation">';
    bar += '<div class="container-fluid">';
    bar += '<div>';
    bar += '<ul class="nav navbar-nav">';
    bar += '<li id="home"><a href="home.html">Home</a></li>';
    bar += '<li id="index"><a href="index.html">Index</a></li>';
    bar += '<li id="about"><a href="about.html">About</a></li>';
    bar += '</ul>';
    bar += '</div>';
    bar += '</div>';
    bar += '</nav>';

    $("#main-bar").html(bar);

    var id = getValueByName("id");
    $("#" + id).addClass("active");
});

function getValueByName(name) {
    var url = document.getElementById('nav-bar').getAttribute('src');
    var param = new Array();
    if (url.indexOf("?") != -1) {
        var source = url.split("?")[1];
        items = source.split("&");
        for (var i = 0; i < items.length; i++) {
            var item = items[i];
            var parameters = item.split("=");
            if (parameters[0] == "id") {
                return parameters[1];
            }
        }
    }
}

Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.

You'll need to unpack the file or use it directly.

If you have a Context, you can use context.getAssets().open("myfoldername/myfilename"); to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File).

It happens if you change your login or password of git service account (GitHub or GitLab, Bitbacket, etc). You need to change it in Windows Credentials Manager too.

So, type "Credential Manager" (rus. "????????? ??????? ??????") in Windows Search menu and go to your git service account and change data too.

select @EmpID = ID from dbo.Employee

Or

set @EmpID =(select id from dbo.Employee)

Note that the select query might return more than one value or rows. so you can write a select query that must return one row.

If you would like to add more columns to one variable(MS SQL), there is an option to use table defined variable

DECLARE @sampleTable TABLE(column1 type1)
INSERT INTO @sampleTable
SELECT columnsNumberEqualInsampleTable FROM .. WHERE ..

As table type variable do not exist in Oracle and others, you would have to define it:

DECLARE TYPE type_name IS TABLE OF (column_type | variable%TYPE | table.column%TYPE [NOT NULL] INDEX BY BINARY INTEGER;

-- Then to declare a TABLE variable of this type: variable_name type_name;

-- Assigning values to a TABLE variable: variable_name(n).field_name := 'some text';

-- Where 'n' is the index value

Just Javascript (as requested)

Add this function somewhere on your page (preferably in the <head>)

function clearBox(elementID)
{
    document.getElementById(elementID).innerHTML = "";
}

Then add the button on click event:

<button onclick="clearBox('cart_item')" />

In JQuery (for reference)

If you prefer JQuery you could do:

$("#cart_item").html("");

Imperative programming
A programming language that requires programming discipline such as C/C++, Java, COBOL, FORTRAN, Perl and JavaScript. Programmers writing in such languages must develop a proper order of actions in order to solve the problem, based on a knowledge of data processing and programming.

Declarative programming
A computer language that does not require writing traditional programming logic; Users concentrate on defining the input and output rather than the program steps required in a procedural programming language such as C++ or Java.

Declarative programming examples are CSS, HTML, XML, XSLT, RegX.

With .NET 4.0 I find System.Threading.Tasks a lot easier to work with. Here's spin-wait loop which works reliably for me. It blocks the main thread until all the tasks complete. There's also Task.WaitAll, but that hasn't always worked for me.

        {
            tasks[i] = Task.Factory.StartNew(() =>
            {               
                 DoThreadStuff(localData);

My use case was to save range to variable and then select it later on

Dim targetRange As Range
Set targetRange = Sheets("Sheet").Range("Name")
Application.Goto targetRange

All the above answers are great. But if you were trying to find a solution that won't change the html files below is helpful

 ngAfterViewChecked(){

}

You can import renderer from import {Renderer} from '@angular/core';

Swift uses backslash to escape double quotes. Here is the list of escaped special characters in Swift:

• \0 (null character)
• \\ (backslash)
• \t (horizontal tab)
• \n (line feed)
• \r (carriage return)
• \" (double quote)
• \' (single quote)

This should work:

text2 = text2.replacingOccurrences(of: "\\", with: "", options: NSString.CompareOptions.literal, range: nil)

Yes, Xamarin is now free in Visual Studio

Since El Capitan, it is difficult to delete the /usr/bin/java symlink, because of the introduction of the new "rootless" policy.

Therefore, I simply added the path to the latest java version (in my case this is /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin) to the PATH in my .bashrc file:

# Use latest java version
export PATH=/Library/Internet\ Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin:$PATH

To reload your .bashrc file for the current session, run source ~/.bashrc in the shell. You only have to do this for sessions that had been started before changing the .bashrc file.

Now the latest version is used, when you use java in the shell.

I had the same problem when I upgraded jquery UI to 1.8.1 without upgrading the corresponding theme. Only is needed to upgrade the theme too and "auto" works again.

Well, if you have a ResultSet of type ResultSet.TYPE_FORWARD_ONLY you want to keep it that way (and not to switch to a ResultSet.TYPE_SCROLL_INSENSITIVE or ResultSet.TYPE_SCROLL_INSENSITIVE in order to be able to use .last()).

I suggest a very nice and efficient hack, where you add a first bogus/phony row at the top containing the number of rows.

Example

Let's say your query is the following

select MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR
from MYTABLE
where ...blahblah...

and your output looks like

true    65537 "Hey" -32768 "The quick brown fox"
false  123456 "Sup"    300 "The lazy dog"
false -123123 "Yo"       0 "Go ahead and jump"
false       3 "EVH"    456 "Might as well jump"
...
[1000 total rows]

Simply refactor your code to something like this:

Statement s=myConnection.createStatement(ResultSet.TYPE_FORWARD_ONLY,
                                         ResultSet.CONCUR_READ_ONLY);
String from_where="FROM myTable WHERE ...blahblah... ";
//h4x
ResultSet rs=s.executeQuery("select count(*)as RECORDCOUNT,"
                           +       "cast(null as boolean)as MYBOOL,"

                           +       "cast(null as char(1))as MYCHAR,"
                           +       "cast(null as smallint)as MYSMALLINT,"
                           +       "cast(null as varchar(1))as MYVARCHAR "
                           +from_where
                           +"UNION ALL "//the "ALL" part prevents internal re-sorting to prevent duplicates (and we do not want that)
                           +"select cast(null as int)as RECORDCOUNT,"
                           +       "MYBOOL,MYINT,MYCHAR,MYSMALLINT,MYVARCHAR "
                           +from_where);

Your query output will now be something like

1000 null     null null    null null
null true    65537 "Hey" -32768 "The quick brown fox"
null false  123456 "Sup"    300 "The lazy dog"
null false -123123 "Yo"       0 "Go ahead and jump"
null false       3 "EVH"    456 "Might as well jump"
...
[1001 total rows]

So you just have to

if(rs.next())
    System.out.println("Recordcount: "+rs.getInt("RECORDCOUNT"));//hack: first record contains the record count
while(rs.next())
    //do your stuff

I think you should do

for index, row in result: 

If you wanna access by name.

One liner for Swift:

NSAttributedString(string: "Red Text", attributes: [.foregroundColor: UIColor.red])

Cool @derek-kromm, Your answer is accepted and correct, But I am wondering if we need to alter more than the column. Here is how we can do.

ALTER TABLE tbl_name 
ALTER COLUMN col_name TYPE varchar (11), 
ALTER COLUMN col_name2 TYPE varchar (11),
ALTER COLUMN col_name3 TYPE varchar (11);

Documentation

Cheers!! Read Simple Write Simple

var http = require('http');
var fs = require('fs');
var index = fs.readFileSync('index.html');

http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/html'});
    // change the to 'text/plain' to 'text/html' it will work as your index page
    res.end(index);
}).listen(9615);

I think you where searching for this. In your index.html, simply fill it with normal html code - whatever you want to render on it, like:

<html>
    <h1>Hello world</h1>
</html>

Am I missing the point here, or is it just the following:

string = "ab1cd1ef"
string = string.replace("1","") 

print string
# result: "abcdef"

Put it in a loop:

a = "a!b@c#d$"
b = "!@#$"
for char in b:
    a = a.replace(char,"")

print a
# result: "abcd"

According to W3:

Partial URLs are interpreted relative to the source of the style sheet, not relative to the document

Therefore, in answer to your question, it will be relative to /stylesheets/.

If you think about this, this makes sense, since the CSS file could be added to pages in different directories, so standardising it to the CSS file means that the URLs will work wherever the stylesheets are linked.

I had a similar issue. pytest did not recognize a module installed in the environment I was working in.

I resolved it by also installing pytest into the same environment.

If you only need to check the first element you can peek on it without iterating the whole collection:

public List<object> Foo(IEnumerable<object> objects)
{
    object firstObject;
    if (objects == null || !TryPeek(ref objects, out firstObject))
        throw new ArgumentException();

    var list = DoSomeThing(firstObject);
    var secondList = DoSomeThingElse(objects);
    list.AddRange(secondList);

    return list;
}

public static bool TryPeek<T>(ref IEnumerable<T> source, out T first)
{
    if (source == null)
        throw new ArgumentNullException(nameof(source));

    IEnumerator<T> enumerator = source.GetEnumerator();
    if (!enumerator.MoveNext())
    {
        first = default(T);
        source = Enumerable.Empty<T>();
        return false;
    }

    first = enumerator.Current;
    T firstElement = first;
    source = Iterate();
    return true;

    IEnumerable<T> Iterate()
    {
        yield return firstElement;
        using (enumerator)
        {
            while (enumerator.MoveNext())
            {
                yield return enumerator.Current;
            }
        }
    }
}

PHP's getimagesize() returns an array of data. The first two items in the array are the two items you're interested in: the width and height. To get these, you would simply request the first two indexes in the returned array:

var $imagedata = getimagesize("someimage.jpg");

print "Image width  is: " . $imagedata[0];
print "Image height is: " . $imagedata[1];

For further information, see the documentation.

When using Bash, the first of ~/.bash_profile, ~/.bash_login and ~/.profile will be run for an interactive login shell. I believe ~/.profile is generally run by Unix shells besides Bash. Bash will run ~/.bashrc for a non-login interactive shell.

I typically put everything I want to always set in .bashrc and then run it from .bash_profile, where I also set up a few things that should run only when I'm logging in, such as setting up ssh-agent or running screen.

There are a lot of answers here, but many overlook a few points. I ran into the same issue and it was likely due to a combination of being a complete neophyte when it comes to tomcat. Even more I am rather new to web servers in general. I consider myself somewhat proficient user of windows, but I guess not proficient enough. In particular I don't work with services too much.

I did not have a startup.bat or any bat files. I only downloaded the 32-bit/64-bit Windows Service Installer. The bin that is created for that download is small - only 4 files. My colleagues were surprised that I did not have a catalina.bat etc... and I was too. Only the below four files in the bin. And no %CATALINA_HOME% or %TOMCAT_HOME% etc...

bootstrap.jar
tomcat-juli.jar
Tomcat7.exe
Tomcat7w.exe

With this setup I had some frustrations as setting parameters is done via the gui widget - very helpful I might add.

So nearly all the answers I have perused were not immediately applicable as many said, "go to bin and issue the startup.bat file" I am a neophyte but not so much to not be able to look into the bin and start such a file it is existed!

For my simple purposes (again remember that I am a neophyte at tomcat and even web servers) all I wanted to do was to be able to startup and shutdown the tomcat server from a cmd prompt window. Nothing too heavy duty. I am embarrassed to say how simple it is. It is probably evident to anyone with a shred of experience with services and such.

To Start server: <Tomcat Root>/bin>Tomcat7.exe start
To Stop server: <Tomcat Root>/bin>Tomcat7.exe stop

Found here - http://crunchify.com/how-to-start-stop-apache-tomcat-server-via-command-line-setup-as-windows-service/

I did not realize there was a separate download the 64-bit Windows zip file that has a tomcat server and all the standard array of cmd line tomcat management tools. This zip file has all the common startup/shutdown scripts, batch files for windows, including catalina.bat/.sh etc... Then all the above answers make sense and are rather trivial.

Remember I am a neophyte when it comes to tomcat and web servers. It appears these two downloads are somewhat mutually exclusive in the sense that if I download and install the 32-bit/64-bit Windows Service Installer version and the 64-bit Windows zip file the startup.bat file in the 64-bit Windows zip file version will not run or interact with the 32-bit/64-bit Windows Service Installer tomcat instance. But I am not sure about this point.

No one mentioned the following, which in my understanding is the correct solution:

Go the csproj of the project where the nuget is installed, and set the AutoGEneratedBindingRedirects to false.

<AutoGenerateBindingRedirects>false</AutoGenerateBindingRedirects>

You need to change your code as below:-

<html>
<body>

<span id="span_Id">Click the button to display the content.</span>

<button onclick="displayDate()">Click Me</button>

<script>
function displayDate() {
   var span_Text = document.getElementById("span_Id").innerText;
   alert (span_Text);
}
</script>
</body>
</html>

After doing this you will get the tag value in alert.

To receive the new commits

git fetch

Reset

You can reset the commit for a local branch using git reset.

To change the commit of a local branch:

git reset origin/master --hard

Be careful though, as the documentation puts it:

Resets the index and working tree. Any changes to tracked files in the working tree since <commit> are discarded.

If you want to actually keep whatever changes you've got locally - do a --soft reset instead. Which will update the commit history for the branch, but not change any files in the working directory (and you can then commit them).

Rebase

You can replay your local commits on top of any other commit/branch using git rebase:

git rebase -i origin/master

This will invoke rebase in interactive mode where you can choose how to apply each individual commit that isn't in the history you are rebasing on top of.

If the commits you removed (with git push -f) have already been pulled into the local history, they will be listed as commits that will be reapplied - they would need to be deleted as part of the rebase or they will simply be re-included into the history for the branch - and reappear in the remote history on the next push.

Use the help git command --help for more details and examples on any of the above (or other) commands.

I have taken UITableView with custom prototype cell class named UITableViewCell inside UIViewController.

So i have ViewController.h, ViewController.m and TableViewCell.h,TableViewCell.m

Here is the code for that:

ViewController.h

@interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>

@property (strong, nonatomic) IBOutlet UITableView *tblView;

@end

ViewController.m

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
    return (YourNumberOfRows);
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{

    static NSString *cellIdentifier = @"cell";

    __weak TableViewCell *cell = (TableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];

    if (indexPath.row==0) {
        [cell setDidTapButtonBlock:^(id sender)
         {
             // Your code here

         }];
    }    
    return cell;
}

Custom cell class :

TableViewCell.h

@interface TableViewCell : UITableViewCell

@property (copy, nonatomic) void (^didTapButtonBlock)(id sender);

@property (strong, nonatomic) IBOutlet UILabel *lblTitle;
@property (strong, nonatomic) IBOutlet UIButton *btnAction;

- (void)setDidTapButtonBlock:(void (^)(id sender))didTapButtonBlock;

@end

and

UITableViewCell.m

@implementation TableViewCell

- (void)awakeFromNib {
    // Initialization code
    [self.btnAction addTarget:self action:@selector(didTapButton:) forControlEvents:UIControlEventTouchUpInside];

}

- (void)setSelected:(BOOL)selected animated:(BOOL)animated {
    [super setSelected:selected animated:animated];

    // Configure the view for the selected state
}
- (void)didTapButton:(id)sender {
    if (self.didTapButtonBlock)
    {
        self.didTapButtonBlock(sender);
    }
}

Note: Here I have taken all UIControls using Storyboard.

Hope that can help you...!!!

You can try below code to solve your problem:

By default, first option select: jQuery('.select').find('option')[0].selected=true;

Thanks, Ketan T

in java 8:

name = Optional.ofNullable(city.getName()).orElse("N/A")

The statement icr=y; does not make the reference refer to y; it assigns the value of y to the variable that icr refers to, i.

References are inherently const, that is you can't change what they refer to. There are 'const references' which are really 'references to const', that is you can't change the value of the object they refer to. They are declared const int& or int const& rather than int& const though.

Uncheck Always Show Toolbar in Full Screen in View menu:

and go to fullscreen then:

Alt+Cmd+F - on Mac

F11 - on Windows

The error is that you cannot initialize a static const char* within the class. You can only initialize integer variables there.

You need to declare the member variable in the class, and then initialize it outside the class:

// header file

class Foo {
    static const char *SOMETHING;
    // rest of class
};

// cpp file

const char *Foo::SOMETHING = "sommething";

If this seems annoying, think of it as being because the initialization can only appear in one translation unit. If it was in the class definition, that would usually be included by multiple files. Constant integers are a special case (which means the error message perhaps isn't as clear as it might be), and compilers can effectively replace uses of the variable with the integer value.

In contrast, a char* variable points to an actual object in memory, which is required to really exist, and it's the definition (including initialization) which makes the object exist. The "one definition rule" means you therefore don't want to put it in a header, because then all translation units including that header would contain the definition. They could not be linked together, even though the string contains the same characters in both, because under current C++ rules you've defined two different objects with the same name, and that's not legal. The fact that they happen to have the same characters in them doesn't make it legal.

How about something as simple as:

function negative(number){
    return number < 0;
}

The * 1 part is to convert strings to numbers.

A library and demo with the complete source code for scrolling toolbars or any type of header can be downloaded here:

https://github.com/JohannBlake/JBHeaderScroll

Headers can be Toolbars, LinearLayouts, RelativeLayouts, or whatever type of view you use to create a header.

The scrollable area can be any type of scroll content including ListView, ScrollView, WebView, RecyclerView, RelativeLayout, LinearLayout or whatever you want.

There's even support for nested headers.

It is indeed a complex undertaking to synchronize headers (toolbars) and scrollable content the way it's done in Google Newsstand.

This library doesn't require implementing any kind of onScrollListener.

The solutions listed above by others are only half baked solutions that don't take into consideration that the top edge of the scrollable content area beneath the toolbar has to initially be aligned to the bottom edge of the toolbar and then during scrolling the content area needs to be repositioned and possibly resized. The JBHeaderScroll handles all these issues.

OK, after making a lot of test, here my concluson:

When you perform:

     window.open('www.yourdomain.tld','_blank');
     window.open('www.yourdomain.tld','myWindow');

or whatever you put in the destination field, this will change nothing: the new page will be opened in a new tab (so depend on user preference)

If you want the page to be opened in a new "real" window, you must put extra parameter. Like:

window.open('www.yourdomain.tld', 'mywindow','location=1,status=1,scrollbars=1, resizable=1, directories=1, toolbar=1, titlebar=1');

After testing, it seems the extra parameter you use, dont' really matter: this is not the fact you put "this parameter" or "this other one" which create the new "real window" but the fact there is new parameter(s).

But something is confused and may explain a lot of wrong answers:

This:

 win1 = window.open('myurl1', 'ID_WIN');
 win2 = window.open('myurl2', 'ID_WIN', 'location=1,status=1,scrollbars=1');

And this:

 win2 = window.open('myurl2', 'ID_WIN', 'location=1,status=1,scrollbars=1');
 win1 = window.open('myurl1', 'ID_WIN');

will NOT give the same result.

In the first case, as you first open a page without extra parameter, it will open in a new tab. And in this case, the second call will be also opened in this tab because of the name you give.

In second case, as your first call is made with extra parameter, the page will be opened in a new "real window". And in that case, even if the second call is made without the extra parameter, it will also be opened in this new "real window"... but same tab!

This mean the first call is important as it decided where to put the page.

we can store session storage like that

store token should be like

 localStorage.setItem('user', JSON.stringify({ token: token, username: username }));

Store Session in to sessionStorage

You can store both string and array into session storage

String Ex.

    let key = 'title'; 
    let value = 'session';
    sessionStorage.setItem(key, value);

Array Ex.

    let key = 'user'; 
    let value = [{'name':'shail','email':'[email protected]'}];

    value = JSON.stringify(value);

    sessionStorage.setItem(key, value);

Get stored session from sessionStorage by key

const session = sessionStorage.getItem('key');

Delete saved session from sessionStorage by key

sessionStorage.removeItem('key');

Delete all saved sessions from sessionStorage

sessionStorage.clear();

2. store Local storage should be like

Store items in to localStorage

You can store both string and array into location storage

String Ex.

 let key = 'title'; 
 let value = 'session';
 localStorage.setItem(key, value);

Array Ex.

let key = 'user'; 
let value = [{'name':'shail','email':'[email protected]'}];

value = JSON.stringify(value);

localStorage.setItem(key, value);

Get stored items from localStorage by key

const item = localStorage.getItem('key');

Delete saved session from localStorage by key

localStorage.removeItem('key');

Delete all saved items from localStorage

localStorage.clear();

You get compile time checking of valid values when you use an enum. Look at this question.

Sometimes you need to grep the process by name - in that case:

ps aux | grep simple-scan

Example output:

simple-scan  1090  0.0  0.1   4248  1432 ?        S    Jun11   0:00

In my case, this error occurred, due to lack of existence of column name in the table.

When i executed "describe tablename" , i was not able to find the column specified in the mapping hbm file.

After altering the table, it worked fine.

I had some big issues with removing the index.php. As a general rule the .htaccess below has been tested on several servers and generally works:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]  

<Files "index.php">
AcceptPathInfo On
</Files>  

If you don't have any luck with that then the next step is to adjust your config file. Try some of the other URI protocols e.g.

| 'AUTO'            Default - auto detects
| 'PATH_INFO'       Uses the PATH_INFO
| 'QUERY_STRING'    Uses the QUERY_STRING
| 'REQUEST_URI'     Uses the REQUEST_URI
| 'ORIG_PATH_INFO'  Uses the ORIG_PATH_INFO

   $config['uri_protocol']  = 'ORIG_PATH_INFO';

If your still not having any luck try changing the rewrite rule to include your subfolder. This is often a problem if your using a temporary URL on a dev server etc:

RewriteRule ^(.*)$ /subofolder1/subfolder2/index.php/$1 [L]  

Just play around with these options, one should work. Also, make sure your index file is set to:

$config['index_page'] = '';

Good luck!

However this answer is simple, infact very simple and yea many have mentioned it that simply put the id of image into the following link https://drive.google.com/uc?export=view&id={fileId}

But however easy that is, I made a script to run in the console. Feed in an array of complete sharable links from google drive and get them converted into the above link. Then they can be simply used as static addresses.

array = ['https://drive.google.com/open?id=0B8kNn6zsgGEtUE5FaGNtcEthNWc','https://drive.google.com/open?id=0B8kNn6zsgGEtM2traVppYkhsV2s','https://drive.google.com/open?id=0B8kNn6zsgGEtNHgzT2x0MThJUlE']_x000D_

function separateDriveImageId(arr) {_x000D_
for (n=0;n<arr.length;n++){_x000D_
_x000D_
str = arr[n]_x000D_
_x000D_
for(i=0;i<str.length;i++){_x000D_
if( str.charAt(i)== '=' ){_x000D_
var num = i+1;_x000D_
var extrctdStrng = str.substr(num)_x000D_
_x000D_
}_x000D_
}_x000D_
console.log('https://drive.google.com/uc?export=view&id='+extrctdStrng)_x000D_
window.open('https://drive.google.com/uc?export=view&id='+extrctdStrng,'_blank')_x000D_
}_x000D_

Simple solution for downloading a file from the server:

protected void btnDownload_Click(object sender, EventArgs e)
        {
            string FileName = "Durgesh.jpg"; // It's a file name displayed on downloaded file on client side.

            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            response.ContentType = "image/jpeg";
            response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
            response.TransmitFile(Server.MapPath("~/File/001.jpg"));
            response.Flush();
            response.End();
        }

You append a newline to both the username and the password, i.e. the output would be something like

Sebastian
password
John
hfsjaijn

use fwrite($fh,$user." ".$password."\n"); instead to have them both on one line.
Or use fputcsv() to write the data and fgetcsv() to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';

...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation (use _POST instead) ;-)

It can be done like this as well:

target.write(line1 + "\n" + line2 + "\n" + line3 + "\n")

I've got this working in a similar situation for moving to next page like this:

$("#page_next").click(function () {
    $("#pageNumber").val(parseInt($("#pageNumber").val()) + 1);
    submitForm(this);
    return false;
});

You should be able to add brackets to achieve what you want something like this:

var newcurrentpageTemp = (parseInt($(this).attr("id"))) + 1;//Get the id from the hyperlink

This will work. Define this, then call it from when you need it. (Good for button logic if you are making a clear button):

Sub ResetFilters()
    On Error Resume Next
    ActiveSheet.ShowAllData
End Sub

The most famous library to create some GUI in C language is certainly GTK.

With this library you can easily create some buttons (for your example). When a user clicks on the button, a signal is emitted and you can write a handler to do some actions.

This function, based on the work by Laurenz Albe at https://www.cybertec-postgresql.com/en/index-your-foreign-key/, list all the foreign keys with missing indexes. The size of the table is shown, as for small tables the scanning performance could be superior to the index one.

Follow the below steps in Eclipse.

1. Goto -> AVD Manager
2. Create/Edit the AVD.
3. Hardware > New:
4. Configures camera facing back
5. Click on the property value and choose = "webcam0".
6. Once done all the above the webcam should be connected. If it doesnt then you need to check your WebCam drivers.

Here's an answer to a 2-year old question in case it helps anyone else with the same problem.

Based upon the information you've provided, a permissions issue on the file (or files) would be one cause of the same 500 Internal Server Error.

To check whether this is the problem (if you can't get more detailed information on the error), navigate to the directory in Terminal and run the following command:

ls -la

If you see limited permissions - e.g. -rw-------@ against your file, then that's your problem.

The solution then is to run chmod 644 on the problem file(s) or chmod 755 on the directories. See this answer - How do I set chmod for a folder and all of its subfolders and files? - for a detailed explanation of how to change permissions.

By way of background, I had precisely the same problem as you did on some files that I had copied over from another Mac via Google Drive, which transfer had stripped most of the permissions from the files.

The screenshot below illustrates. The index.php file with the -rw-------@ permissions generates a 500 Internal Server Error, while the index_finstuff.php (precisely the same content!) with -rw-r--r--@ permissions is fine. Changing the permissions on the index.php immediately resolves the problem.

In other words, your PHP code and the server may both be fine. However, the limited read permissions on the file may be forbidding the server from displaying the content, causing the 500 Internal Server Error message to be displayed instead.

The second one tends to be faster in some browsers, but the main point is that you have to use it because the first one is just not cross-browser. Even though The Times They Are a-Changin'

@kangax (IE 9 preview)

Array.prototype.slice can now convert certain host objects (e.g. NodeList’s) to arrays — something that majority of modern browsers have been able to do for quite a while.

Example:

Array.prototype.slice.call(document.childNodes);

Just in case y'all end up here in 2013 - here is a pure css approach I found here: http://css-tricks.com/snippets/css/truncate-string-with-ellipsis/

.truncate {
  width: 250px;
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
}

It works well.

Select First two Character in selected Field with Left(string,Number of Char in int)

SELECT LEFT(FName, 2) AS FirstName FROM dbo.NameMaster

use jackson to convert json input stream to the map or object http://jackson.codehaus.org/

there are also some other usefull libraries for json, you can google: json java

There are various classes for different size inputs

 :class=>"input-mini"

 :class=>"input-small"

 :class=>"input-medium"

 :class=>"input-large"

 :class=>"input-xlarge"

 :class=>"input-xxlarge"

Why don't you just use .to_frame if both have the same indexes?

>= v0.23

a.to_frame().join(b)

< v0.23

a.to_frame().join(b.to_frame())

in your code, just after 'do while' statement, add this line..

`Wscript.sleep 10000`

This will let your script sleep for 10 secs and let your system take rest. Else your processor will be running this script million times a second and this will definitely load your processor.

To kill it, just goto taskmanager and kill wscript.exe or if it is not found, you will find cscript.exe, kill it pressing delete button. These would be present in process tab of your taskmanager.

Once you add that line in code, I dont think you need to kill this process. It will not load your CPU.

Have a great day.

You can simply use:

List<string> items = new List<string>() { "foo", "boo", "john", "doe" };

Console.WriteLine(string.Join(",", items));

Happy coding!

I was having a similar issue with my button. I included line-height: 0; and it appears to have worked. Also mentioned by @anddero.

button[type=submit] {
  background-color: #4056A1;
  border-radius: 12px;
  border: 1px solid #4056A1;
  color: white;
  padding: 16px 32px;
  text-decoration: none;
  margin: 2px 1px;
  cursor: pointer;
  display: inline-block;
  font-size: 16px;
  height: 20px;
  line-height: 0;
}

Navigate to file -> Project structure -> modules -> click on green plus button to add a module.

Select new module -> select Application Module in Android option -> give a module name -> next -> next -> finish

Select project that to be include in module -> click apply -> okay

Now you will be able to see the full project structure; then open the module form project window (the left panel), select res then select layout -> your layout name(.xml).

Now you will be able to see the design view and text view both...

You can use unset:

unset($array['key-here']);

Example:

$array = array("key1" => "value1", "key2" => "value2");
print_r($array);

unset($array['key1']);
print_r($array);

unset($array['key2']);
print_r($array);

Output:

Array
(
    [key1] => value1
    [key2] => value2
)
Array
(
    [key2] => value2
)
Array
(
)

Kind of an old question, but I arrived here looking for this. I wanted the table to be as small as possible, fitting to it's contents. The solution was to simply set the table width to an arbitrary small number (1px for example). I even created a CSS class to handle it:

.table-fit {
    width: 1px;
}

And use it like so:

<table class="table table-fit">

Example: JSFiddle

Since Java 8 you can sort using the Streams API:

List<String> fruits = Arrays.asList("apple", "Apricot", "banana");

List<String> sortedFruit = fruits.stream()
      .sorted(String.CASE_INSENSITIVE_ORDER)
      .collect(Collectors.toList())

The difference with Collections.sort is that this will return a new list and will not modify the existing one.

C99 defines "%zd" etc. for that. (thanks to the commenters) There is no portable format specifier for that in C++ - you could use %p, which woulkd word in these two scenarios, but isn't a portable choice either, and gives the value in hex.

Alternatively, use some streaming (e.g. stringstream) or a safe printf replacement such as Boost Format. I understand that this advice is only of limited use (and does require C++). (We've used a similar approach fitted for our needs when implementing unicode support.)

The fundamental problem for C is that printf using an ellipsis is unsafe by design - it needs to determine the additional argument's size from the known arguments, so it can't be fixed to support "whatever you got". So unless your compiler implement some proprietary extensions, you are out of luck.

I've just stumbled upon this problem too, learning React, and solved it by showing spinner until the data is ready.

    render() {
    if (this.state.data === null) {
        return (
            <div className="MyView">
                <Spinner/>
            </div>
        );
    }
    else {
        return(
            <div className="MyView">
                <ReactJson src={this.state.data}/>
            </div>
        );
    }
}

I am assuming (please correct me if I am wrong) that you want to re-display the edit page if the edit fails and to do this you are using a redirect.

You may have more luck by just returning the view again rather than trying to redirect the user, this way you will be able to use the ModelState to output any errors too.

Edit:

Updated based on feedback. You can place the previous URL in the viewModel, add it to a hidden field then use it again in the action that saves the edits.

For instance:

public ActionResult Index()
{
    return View();
}

[HttpGet] // This isn't required
public ActionResult Edit(int id)
{
   // load object and return in view
   ViewModel viewModel = Load(id);

   // get the previous url and store it with view model
   viewModel.PreviousUrl = System.Web.HttpContext.Current.Request.UrlReferrer;

   return View(viewModel);
}

[HttpPost]
public ActionResult Edit(ViewModel viewModel)
{
   // Attempt to save the posted object if it works, return index if not return the Edit view again

   bool success = Save(viewModel);
   if (success)
   {
       return Redirect(viewModel.PreviousUrl);
   }
   else
   {
      ModelState.AddModelError("There was an error");
      return View(viewModel);
   }
}

The BeginForm method for your view doesn't need to use this return URL either, you should be able to get away with:

@model ViewModel

@using (Html.BeginForm())
{
    ...
    <input type="hidden" name="PreviousUrl" value="@Model.PreviousUrl" />
}

Going back to your form action posting to an incorrect URL, this is because you are passing a URL as the 'id' parameter, so the routing automatically formats your URL with the return path.

This won't work because your form will be posting to an controller action that won't know how to save the edits. You need to post to your save action first, then handle the redirect within it.

You should check that fractional part of the number is 0. Use

x==Math.ceil(x)

or

x==Math.round(x)

or something like that

We can simulate constructor overload using guards

interface IUser {
  name: string;
  lastName: string;
}

interface IUserRaw {
  UserName: string;
  UserLastName: string;
}

function isUserRaw(user): user is IUserRaw {
  return !!(user.UserName && user.UserLastName);
}

class User {
  name: string;
  lastName: string;

  constructor(data: IUser | IUserRaw) {
    if (isUserRaw(data)) {
      this.name = data.UserName;
      this.lastName = data.UserLastName;
    } else {
      this.name = data.name;
      this.lastName = data.lastName;
    }
  }
}

const user  = new User({ name: "Jhon", lastName: "Doe" })
const user2 = new User({ UserName: "Jhon", UserLastName: "Doe" })

Set texts with different sizes and styles, and size and style for texts from cells ( with Range)

Sub EmailManuellAbsenden()

Dim ghApp As Object
Dim ghOldBody As String
Dim ghNewBody As String

Set ghApp = CreateObject("Outlook.Application")
With ghApp.CreateItem(0)
.To = Range("B2")
.CC = Range("B3")
.Subject = Range("B4")
.GetInspector.Display
 ghOldBody = .htmlBody

 ghNewBody = "<font style=""font-family: Calibri; font-size: 11pt;""/font>" & _
 "<font style=""font-family: Arial; font-size: 14pt;"">Arial Text 14</font>" & _
 Range("B5") & "<br>" & _
 Range("B6") & "<br>" & _
 "<font style=""font-family: Chiller; font-size: 21pt;"">Ciller 21</font>" &
 Range("B5")
 .htmlBody = ghNewBody & ghOldBody

 End With

End Sub
'Fill B2 to B6 with some letters for testing
'"<font style=""font-family: Calibri; font-size: 15pt;""/font>" = works for all Range Objekts

If the verification logic is non-trivial, it will be messy to write a large lambda method (as your example shows). You could put all the test statements in a separate method, but I don't like to do this because it disrupts the flow of reading the test code.

Another option is to use a callback on the Setup call to store the value that was passed into the mocked method, and then write standard Assert methods to validate it. For example:

// Arrange
MyObject saveObject;
mock.Setup(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()))
        .Callback<int, MyObject>((i, obj) => saveObject = obj)
        .Returns("xyzzy");

// Act
// ...

// Assert
// Verify Method was called once only
mock.Verify(c => c.Method(It.IsAny<int>(), It.IsAny<MyObject>()), Times.Once());
// Assert about saveObject
Assert.That(saveObject.TheProperty, Is.EqualTo(2));

Date Between Query

SELECT *
    FROM emp
    WHERE HIREDATE between to_date (to_char(sysdate, 'yyyy') ||'/09/01', 'yyyy/mm/dd')
    AND to_date (to_char(sysdate, 'yyyy') + 1|| '/08/31', 'yyyy/mm/dd');

If it's a deeper key/value you're after and you're not dealing with arrays of keys/values at each level, you could recursively search the tree:

public static String recurseKeys(JSONObject jObj, String findKey) throws JSONException {
    String finalValue = "";
    if (jObj == null) {
        return "";
    }

    Iterator<String> keyItr = jObj.keys();
    Map<String, String> map = new HashMap<>();

    while(keyItr.hasNext()) {
        String key = keyItr.next();
        map.put(key, jObj.getString(key));
    }

    for (Map.Entry<String, String> e : (map).entrySet()) {
        String key = e.getKey();
        if (key.equalsIgnoreCase(findKey)) {
            return jObj.getString(key);
        }

        // read value
        Object value = jObj.get(key);

        if (value instanceof JSONObject) {
            finalValue = recurseKeys((JSONObject)value, findKey);
        }
    }

    // key is not found
    return finalValue;
}

Usage:

JSONObject jObj = new JSONObject(jsonString);
String extract = recurseKeys(jObj, "extract");

Using Map code from https://stackoverflow.com/a/4149555/2301224

Try this:

 DatePicker datePicker = (DatePicker) findViewById(R.id.datePicker1);
 int day = datePicker.getDayOfMonth();
 int month = datePicker.getMonth() + 1;
 int year = datePicker.getYear();

You can usee the following code: week_start = str(datetime.today() - timedelta(days=datetime.today().weekday() % 7)).split(' ')[0]

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

I haven't seen someone mention this method but document.createElementNS() is helpful in this instance.

You can create the elements using vanilla Javascript as normal DOM nodes with the correct namespace and then jQuery-ify them from there. Like so:

var svg = document.createElementNS('http://www.w3.org/2000/svg', 'svg'),
    circle = document.createElementNS('http://www.w3.org/2000/svg', 'circle');

var $circle = $(circle).attr({ //All your attributes });

$(svg).append($circle);

The only down side is that you have to create each SVG element with the right namespace individually or it won't work.

Running powershell scripts on linux from bash gives the same problem. Solved it almost the same as LarsWA's answer:

Working:

pwsh -f ./test.ps1 -bool:true

Not working:

pwsh -f ./test.ps1 -bool=1
pwsh -f ./test.ps1 -bool=true
pwsh -f ./test.ps1 -bool true
pwsh -f ./test.ps1 {-bool=true}
pwsh -f ./test.ps1 -bool=$true
pwsh -f ./test.ps1 -bool=\$true
pwsh -f ./test.ps1 -bool 1
pwsh -f ./test.ps1 -bool:1

Create a bi-directional relationship, like this:

@Entity
public class Parent implements Serializable {

    @Id
    @GeneratedValue
    private long id;

    @OneToMany(mappedBy = "parent", cascade = CascadeType.REMOVE)
    private Set<Child> children;
}

I don't think you can both within the same jenkins job, what you need to do is to configure a new jenkins job which will have access to your github to retrieve branches and then you can choose which one to manually build.

Just mark it as a parameterized build, specify a name, and a parameter configured as git parameter

and now you can configure git options:

In config/app.php file make a instance of env variable like 'name' => env('APP_NAME', 'Laravel') & In your controller call it like config('app.name')

Run following commands php artisan config:cache php artisan cache:clear if it is not working.

DateTime.FromFileTime should do the trick:

PS C:\> [datetime]::FromFileTime(129948127853609000)

Monday, October 15, 2012 3:13:05 PM

Then depending on how you want to format it, check out standard and custom datetime format strings.

PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('d MMMM')
15 October
PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('g')
10/15/2012 3:13 PM

If you want to integrate this into your one-liner, change your select statement to this:

... | Select Name, manager, @{N='LastLogon'; E={[DateTime]::FromFileTime($_.LastLogon)}} | ...

Assuming there is a table config with unique index on config_code column:

CONFIG_CODE     PARAM1   PARAM2
--------------- -------- --------
default_config  def      000
config1         abc      123
config2         def      456

This query returns line for config1 values, because it exists in the table:

SELECT *
  FROM (SELECT *
          FROM config
         WHERE config_code = 'config1'
            OR config_code = 'default_config'
         ORDER BY CASE config_code WHEN 'default_config' THEN 999 ELSE 1 END)
 WHERE rownum = 1;

CONFIG_CODE     PARAM1   PARAM2
--------------- -------- --------
config1         abc      123

This one returns default record as config3 doesn't exist in the table:

SELECT *
  FROM (SELECT *
          FROM config
         WHERE config_code = 'config3'
            OR config_code = 'default_config'
         ORDER BY CASE config_code WHEN 'default_config' THEN 999 ELSE 1 END)
 WHERE rownum = 1;

CONFIG_CODE     PARAM1   PARAM2
--------------- -------- --------
default_config  def      000

In comparison with other solutions this one queries table config only once.

Creating Custom ProgressBar like hotstar.

1. Add Progress bar on layout file and set the indeterminateDrawable with drawable file.

activity_main.xml

<ProgressBar
    style="?android:attr/progressBarStyleLarge"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:id="@+id/player_progressbar"
    android:indeterminateDrawable="@drawable/custom_progress_bar"
    />

2. Create new xml file in res\drawable

custom_progress_bar.xml

<?xml version="1.0" encoding="utf-8"?>
    <rotate  xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="2000"
    android:fromDegrees="0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:toDegrees="1080" >

    <shape
        android:innerRadius="35dp"
        android:shape="ring"
        android:thickness="3dp"
        android:useLevel="false" >
       <size
           android:height="80dp"
           android:width="80dp" />

       <gradient
            android:centerColor="#80b7b4b2"
            android:centerY="0.5"
            android:endColor="#f4eef0"
            android:startColor="#00938c87"
            android:type="sweep"
            android:useLevel="false" />
    </shape>

</rotate>

By using Spring 3.1.x and 3.2.x, this is how you should do it:

The controller method:

@RequestMapping("/photo2")
public @ResponseBody byte[] testphoto() throws IOException {
    InputStream in = servletContext.getResourceAsStream("/images/no_image.jpg");
    return IOUtils.toByteArray(in);
}

And the mvc annotation in servlet-context.xml file:

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter">
            <property name="supportedMediaTypes">
                <list>
                    <value>image/jpeg</value>
                    <value>image/png</value>
                </list>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

I just use contentsMargin to fix the aspect ratio.

#pragma once

#include <QLabel>

class AspectRatioLabel : public QLabel
{
public:
    explicit AspectRatioLabel(QWidget* parent = nullptr, Qt::WindowFlags f = Qt::WindowFlags());
    ~AspectRatioLabel();

public slots:
    void setPixmap(const QPixmap& pm);

protected:
    void resizeEvent(QResizeEvent* event) override;

private:
    void updateMargins();

    int pixmapWidth = 0;
    int pixmapHeight = 0;
};

#include "AspectRatioLabel.h"

AspectRatioLabel::AspectRatioLabel(QWidget* parent, Qt::WindowFlags f) : QLabel(parent, f)
{
}

AspectRatioLabel::~AspectRatioLabel()
{
}

void AspectRatioLabel::setPixmap(const QPixmap& pm)
{
    pixmapWidth = pm.width();
    pixmapHeight = pm.height();

    updateMargins();
    QLabel::setPixmap(pm);
}

void AspectRatioLabel::resizeEvent(QResizeEvent* event)
{
    updateMargins();
    QLabel::resizeEvent(event);
}

void AspectRatioLabel::updateMargins()
{
    if (pixmapWidth <= 0 || pixmapHeight <= 0)
        return;

    int w = this->width();
    int h = this->height();

    if (w <= 0 || h <= 0)
        return;

    if (w * pixmapHeight > h * pixmapWidth)
    {
        int m = (w - (pixmapWidth * h / pixmapHeight)) / 2;
        setContentsMargins(m, 0, m, 0);
    }
    else
    {
        int m = (h - (pixmapHeight * w / pixmapWidth)) / 2;
        setContentsMargins(0, m, 0, m);
    }
}

Works perfectly for me so far. You're welcome.

This code works too:

$("input[reference=12345].myclass").css('border', '#000 solid 1px');

You can save the best model using keras.callbacks.ModelCheckpoint()

Example:

model.compile(loss='categorical_crossentropy', optimizer='adam', metrics=['accuracy'])
model_checkpoint_callback = keras.callbacks.ModelCheckpoint("best_Model.h5",save_best_only=True)
history = model.fit(x_train,y_train,
          epochs=10,
          validation_data=(x_valid,y_valid),
          callbacks=[model_checkpoint_callback])

This will save the best model in your working directory.

The PropertiesPlaceholderConfigurer bean has an alternative property called "propertiesArray". Use this instead of the "properties" property, and configure it with an <array> of property references.

I used the code below to create a Button and it worked for me.

<input type="button" value="PDF" onclick="location.href='@Url.Action("Export","tblOrder")'"/>

problem in %time:~0,2% can't set to 24 hrs format, ended with space(1-9), instead of 0(1-9)

go around with:

set HR=%time:~0,2%

set HR=%Hr: =0% (replace space with 0 if any <has a space in between : =0>)

then replace %time:~0,2% with %HR%

good luck
