I have used this URL to obtain multiple currency market quotes.

http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=USD=X,CAD=X,EUR=X

"USD",1.0000
"CAD",1.2458
"EUR",0.8396

They can be parsed in PHP like this:

$symbols = ['USD=X', 'CAD=X', 'EUR=X'];
$url = "http://finance.yahoo.com/d/quotes.csv?e=.csv&f=c4l1&s=".join($symbols, ',');

$quote = array_map( 'str_getcsv', file($url) );

foreach ($quote as $key => $symb) {
    $symbol = $quote[$key][0];
    $value = $quote[$key][1];
}

Example to recieve it through a request:

a) http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.historical

OR

b) http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.quotes

In my case I kept the project on desktop and to access the desktop we need to add permission to the folder so I simply moved my project folder to C:\ directory now its working like a charm.

You code is correct. replace items with .items as below

<script>
  var n = $(".items").css("left");
  if(n == -900){
    $(".items span").fadeOut("slow");
  }
</script>

Laravel Server Requirements mention that BCMath, Ctype, JSON, Mbstring, OpenSSL, PDO, Tokenizer, and XML extensions are required. Most of the extensions are installed and enabled by default.

You can run the following command in Ubuntu to make sure the extensions are installed.

sudo apt install openssl php-common php-curl php-json php-mbstring php-mysql php-xml php-zip

PHP version specific installation (if PHP 7.4 installed)

sudo apt install php7.4-common php7.4-bcmath openssl php7.4-json php7.4-mbstring

You may need other PHP extensions for your composer packages. Find from links below.

To match regexes you need to use the =~ operator.

Try this:

[[ sed-4.2.2.tar.bz2 =~ tar.bz2$ ]] && echo matched

Alternatively, you can use wildcards (instead of regexes) with the == operator:

[[ sed-4.2.2.tar.bz2 == *tar.bz2 ]] && echo matched

If portability is not a concern, I recommend using [[ instead of [ or test as it is safer and more powerful. See What is the difference between test, [ and [[ ? for details.

String url = "https://www.thandroid-mania.com/";

That error occurred because of invalid URL, Android OS can't find action view for your data. So you have validate that the URL is valid or not.

For anyone struggling with this issue, I just found out that the Geocoding API can't be used with API keys that have referrer restrictions. Just remove all your referrer restrictions and you should be good.

If you're using any other APIs that do allow keys with referrer restrictions (like the Maps JS API), it's probably best to create a 2nd key with no restrictions to use exclusively for geocoding, because other APIs might display your key publicly and someone else could start using it on their own site.

As you've said you don't want to set up your own repository, perhaps this will help.

You can use the install-file goal of the maven-install-plugin to install a file to the local repository. If you create a script with a Maven invocation for each file and keep it alongside the jars, you (and anyone else with access) can easily install the jars (and associated pom files) to their local repository.

For example:

mvn install:install-file -Dfile=/usr/jars/foo.jar -DpomFile=/usr/jars/foo.pom
mvn install:install-file -Dfile=/usr/jars/bar.jar -DpomFile=/usr/jars/bar.pom

or just

mvn install:install-file -Dfile=ojdbc14.jar -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0 -Dpackaging=jar

You can then reference the dependencies as normal in your project.

However your best bet is still to set up an internal remote repository and I'd recommend using Nexus myself. It can run on your development box if needed, and the overhead is minimal.

Please try this: playButton = (Button) findViewById(R.id.play); playButton.setVisibility(View.INVISIBLE); I think this will do it.

If you use cmd

sudo chown -R $USER:www-data storage
sudo chown -R $USER:www-data bootstrap/cache

If you use GUI

First go to the project and right click on the storage and check the properties and go to the Permissions tab

Change the permissions using below code

sudo chmod -R 777 storage

Then your file properties may be

Then check your settings and execute laravel command it will work :)

I have a simpler method that works for me. Basically, remember what the hash actually is in HTML. It's an anchor link to a Name tag. That's why it scrolls...the browser is attempting to scroll to an anchor link. So, give it one!

1. Right under the BODY tag, put your version of this:

 <a name="home"></a><a name="firstsection"></a><a name="secondsection"></a><a name="thirdsection"></a>

2. Name your section divs with classes instead of IDs.

3. In your processing code, strip off the hash mark and replace with a dot:

    var trimPanel = loadhash.substring(1);    //lose the hash

    var dotSelect = '.' + trimPanel;  //replace hash with dot

    $(dotSelect).addClass("activepanel").show();        //show the div associated with the hash.

Finally, remove element.preventDefault or return: false and allow the nav to happen. The window will stay at the top, the hash will be appended to the address bar url, and the correct panel will open.

This code will print all the keys with maximum value

public class NewClass4 {
    public static void main(String[] args)
    {
        HashMap<Integer,Integer>map=new HashMap<Integer, Integer>();
        map.put(1, 50);
        map.put(2, 60);
        map.put(3, 30);
        map.put(4, 60);
        map.put(5, 60);
        int maxValueInMap=(Collections.max(map.values()));  // This will return max value in the Hashmap
        for (Entry<Integer, Integer> entry : map.entrySet()) {  // Itrate through hashmap
            if (entry.getValue()==maxValueInMap) {
                System.out.println(entry.getKey());     // Print the key with max value
            }
        }

    }
}

Since the reduce method has been removed from the built in function from Python3, don't forget to import the functools in your code. Please look at the code snippet below.

import functools
my_list = [10,15,20,25,35]
sum_numbers = functools.reduce(lambda x ,y : x+y , my_list)
print(sum_numbers)

Jauco posted a good solution in a comment, so I'm copying it here:

$(elem)
  .contents()
  .filter(function() {
    return this.nodeType === 3; //Node.TEXT_NODE
  });

The solution suggested in this answer has been deprecated, and might no longer work.

Taking a look at the source code of OpenPyXL (IterableWorksheet) I've figured out how to get the column and row count from an iterator worksheet:

wb = load_workbook(path, use_iterators=True)
sheet = wb.worksheets[0]

row_count = sheet.get_highest_row() - 1
column_count = letter_to_index(sheet.get_highest_column()) + 1

IterableWorksheet.get_highest_column returns a string with the column letter that you can see in Excel, e.g. "A", "B", "C" etc. Therefore I've also written a function to translate the column letter to a zero based index:

def letter_to_index(letter):
    """Converts a column letter, e.g. "A", "B", "AA", "BC" etc. to a zero based
    column index.

    A becomes 0, B becomes 1, Z becomes 25, AA becomes 26 etc.

    Args:
        letter (str): The column index letter.
    Returns:
        The column index as an integer.
    """
    letter = letter.upper()
    result = 0

    for index, char in enumerate(reversed(letter)):
        # Get the ASCII number of the letter and subtract 64 so that A
        # corresponds to 1.
        num = ord(char) - 64

        # Multiply the number with 26 to the power of `index` to get the correct
        # value of the letter based on it's index in the string.
        final_num = (26 ** index) * num

        result += final_num

    # Subtract 1 from the result to make it zero-based before returning.
    return result - 1

I still haven't figured out how to get the column sizes though, so I've decided to use a fixed-width font and automatically scaled columns in my application.

If you are using AngularJS, you can use $routeParams using ngRoute module

You have to add a module to your app

angular.module('myApp', ['ngRoute'])

Now you can use service $routeParams:

.controller('AppCtrl', function($routeParams) {
  console.log($routeParams); // JSON object
}

[edit on 2009-04-21]

    As Micah pointed out, this only works when you have named that
    particular range (hence .Name anyone?) Yeah, oops!

[/edit]

A little late to the party, I know, but in case anyone else catches this in a google search (as I just did), you could also try the following:

Dim cell as Range
Dim address as String
Set cell = Sheet1.Range("A1")
address = cell.Name

This should return the full address, something like "=Sheet1!$A$1".

Assuming you don't want the equal sign, you can strip it off with a Replace function:

address = Replace(address, "=", "")

I was facing simillar issue and answer suggested by S.Lott worked for me.

<script type="text/javascript"> 
   var a = "{{someDjangoVariable}}"
</script>

However I would like to point out major implementation limitation here. If you are planning to put your javascript code in different file and include that file in your template. This won't work.

This works only when you main template and javascript code is in same file. Probably django team can address this limitation.

With the Netbeans 10, commenting out the netbeans_jdkhome setting in .../etc/netbeans.conf doesn't do the job anymore. It is necessary to specify the right directory depending of 32/64 bitness.

E.g. for 64 bit application: netbeans_jdkhome="C:\Program Files\AdoptOpenJDK\jdk8u202-b08"

I had the same problem with a stripes taglib uri showing as not found. I was using Indigo and Maven and when I checked Properties->Java Build Path->Order & Export Tab I found (on a fresh project checkout) that the "Maven Dependencies" checkbox was unchecked for some reason. Simply checking that box and doing a Maven clean install cleared all the errors.

I wonder why Eclipse doesn't assume I want my Maven dependencies in the build path...

Anyone looking for this functionality past 2018: it's much cleaner to do this with just CSS using position: sticky.

position: sticky doesn't work with some table elements (thead/tr) in Chrome. You can move sticky to tds/ths of tr you need to be sticky. Like this:

thead tr:nth-child(1) th {
  background: white;
  position: sticky;
  top: 0;
  z-index: 10;
}

Simply put the line:

new_list = set(your_list)

Documentation from npm for npm install <package-name> --save and npm install <package-name> --save-dev can be found here:

https://docs.npmjs.com/getting-started/using-a-package.json#the-save-and-save-dev-install-flags

A package.json file declares metadata about the module you are developing. Both aforementioned commands modify this package.json file. --save will declare the installed package (in this case, grunt) as a dependency for your module; --save-dev will declare it as a dependency for development of your module.

Ask yourself: will the installed package be required for use of my module, or will it only be required for developing it?

You can compile with either Cygwin's g++ or MinGW (via stand-alone or using Cygwin package). However, in order to run it, you need to add the Cygwin1.dll (and others) PATH to the system Windows PATH, before any cygwin style paths.

Thus add: ;C:\cygwin64\bin to the end of your Windows system PATH variable.

Also, to compile for use in CMD or PowerShell, you may need to use:

x86_64-w64-mingw32-g++.exe -static -std=c++11 prog_name.cc -o prog_name.exe

_{(This invokes the cross-compiler, if installed.)}

If you use setState inside componentDidUpdate it updates the component, resulting in a call to componentDidUpdate which subsequently calls setState again resulting in the infinite loop. You should conditionally call setState and ensure that the condition violating the call occurs eventually e.g:

componentDidUpdate: function() {
    if (condition) {
        this.setState({..})
    } else {
        //do something else
    }
}

In case you are only updating the component by sending props to it(it is not being updated by setState, except for the case inside componentDidUpdate), you can call setState inside componentWillReceiveProps instead of componentDidUpdate.

You can use a $ sign like:

OUTPUT=$(expression)

#include <iostream>
#include <sstream>

std::string input = "abc,def,ghi";
std::istringstream ss(input);
std::string token;

while(std::getline(ss, token, ',')) {
    std::cout << token << '\n';
}

abc
def
ghi

You could default the parameter to null or false.
This way, it would be shorter to test if a value has been passed as parameter.

@mixin clearfix($width: null) {

  @if not ($width) {

    // if width is not passed, or empty do this

  } @else {

    display: inline-block;
    width: $width;

  }
}

High level.... You need to have a cname setup on your server so that other-serve.your-server.com points to other-server.com.

Your page dynamically creates an invisible iframe, which acts as your transport to other-server.com. You then have to communicate via JS from your page to the other-server.com and have call backs that return the data back to your page.

Possible but requires coordination from your-server.com and other-server.com

You can just use git diff to produce a unified diff suitable for git apply:

git diff tag1..tag2 > mypatch.patch

You can then apply the resulting patch with:

git apply mypatch.patch

Calling a generic method with a type parameter known only at runtime can be greatly simplified by using a dynamic type instead of the reflection API.

To use this technique the type must be known from the actual object (not just an instance of the Type class). Otherwise, you have to create an object of that type or use the standard reflection API solution. You can create an object by using the Activator.CreateInstance method.

If you want to call a generic method, that in "normal" usage would have had its type inferred, then it simply comes to casting the object of unknown type to dynamic. Here's an example:

class Alpha { }
class Beta { }
class Service
{
    public void Process<T>(T item)
    {
        Console.WriteLine("item.GetType(): " + item.GetType()
                          + "\ttypeof(T): " + typeof(T));
    }
}

class Program
{
    static void Main(string[] args)
    {
        var a = new Alpha();
        var b = new Beta();

        var service = new Service();
        service.Process(a); // Same as "service.Process<Alpha>(a)"
        service.Process(b); // Same as "service.Process<Beta>(b)"

        var objects = new object[] { a, b };
        foreach (var o in objects)
        {
            service.Process(o); // Same as "service.Process<object>(o)"
        }
        foreach (var o in objects)
        {
            dynamic dynObj = o;
            service.Process(dynObj); // Or write "service.Process((dynamic)o)"
        }
    }
}

And here's the output of this program:

item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta
item.GetType(): Alpha    typeof(T): System.Object
item.GetType(): Beta     typeof(T): System.Object
item.GetType(): Alpha    typeof(T): Alpha
item.GetType(): Beta     typeof(T): Beta

Process is a generic instance method that writes the real type of the passed argument (by using the GetType() method) and the type of the generic parameter (by using typeof operator).

By casting the object argument to dynamic type we deferred providing the type parameter until runtime. When the Process method is called with the dynamic argument then the compiler doesn't care about the type of this argument. The compiler generates code that at runtime checks the real types of passed arguments (by using reflection) and choose the best method to call. Here there is only this one generic method, so it's invoked with a proper type parameter.

In this example, the output is the same as if you wrote:

foreach (var o in objects)
{
    MethodInfo method = typeof(Service).GetMethod("Process");
    MethodInfo generic = method.MakeGenericMethod(o.GetType());
    generic.Invoke(service, new object[] { o });
}

The version with a dynamic type is definitely shorter and easier to write. You also shouldn't worry about performance of calling this function multiple times. The next call with arguments of the same type should be faster thanks to the caching mechanism in DLR. Of course, you can write code that cache invoked delegates, but by using the dynamic type you get this behaviour for free.

If the generic method you want to call don't have an argument of a parametrized type (so its type parameter can't be inferred) then you can wrap the invocation of the generic method in a helper method like in the following example:

class Program
{
    static void Main(string[] args)
    {
        object obj = new Alpha();

        Helper((dynamic)obj);
    }

    public static void Helper<T>(T obj)
    {
        GenericMethod<T>();
    }

    public static void GenericMethod<T>()
    {
        Console.WriteLine("GenericMethod<" + typeof(T) + ">");
    }
}

Increased type safety

What is really great about using dynamic object as a replacement for using reflection API is that you only lose compile time checking of this particular type that you don't know until runtime. Other arguments and the name of the method are staticly analysed by the compiler as usual. If you remove or add more arguments, change their types or rename method name then you'll get a compile-time error. This won't happen if you provide the method name as a string in Type.GetMethod and arguments as the objects array in MethodInfo.Invoke.

Below is a simple example that illustrates how some errors can be caught at compile time (commented code) and other at runtime. It also shows how the DLR tries to resolve which method to call.

interface IItem { }
class FooItem : IItem { }
class BarItem : IItem { }
class Alpha { }

class Program
{
    static void Main(string[] args)
    {
        var objects = new object[] { new FooItem(), new BarItem(), new Alpha() };
        for (int i = 0; i < objects.Length; i++)
        {
            ProcessItem((dynamic)objects[i], "test" + i, i);

            //ProcesItm((dynamic)objects[i], "test" + i, i);
            //compiler error: The name 'ProcesItm' does not
            //exist in the current context

            //ProcessItem((dynamic)objects[i], "test" + i);
            //error: No overload for method 'ProcessItem' takes 2 arguments
        }
    }

    static string ProcessItem<T>(T item, string text, int number)
        where T : IItem
    {
        Console.WriteLine("Generic ProcessItem<{0}>, text {1}, number:{2}",
                          typeof(T), text, number);
        return "OK";
    }
    static void ProcessItem(BarItem item, string text, int number)
    {
        Console.WriteLine("ProcessItem with Bar, " + text + ", " + number);
    }
}

Here we again execute some method by casting the argument to the dynamic type. Only verification of first argument's type is postponed to runtime. You will get a compiler error if the name of the method you're calling doesn't exist or if other arguments are invalid (wrong number of arguments or wrong types).

When you pass the dynamic argument to a method then this call is lately bound. Method overload resolution happens at runtime and tries to choose the best overload. So if you invoke the ProcessItem method with an object of BarItem type then you'll actually call the non-generic method, because it is a better match for this type. However, you'll get a runtime error when you pass an argument of the Alpha type because there's no method that can handle this object (a generic method has the constraint where T : IItem and Alpha class doesn't implement this interface). But that's the whole point. The compiler doesn't have information that this call is valid. You as a programmer know this, and you should make sure that this code runs without errors.

Return type gotcha

When you're calling a non-void method with a parameter of dynamic type, its return type will probably be dynamic too. So if you'd change previous example to this code:

var result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

then the type of the result object would be dynamic. This is because the compiler don't always know which method will be called. If you know the return type of the function call then you should implicitly convert it to the required type so the rest of the code is statically typed:

string result = ProcessItem((dynamic)testObjects[i], "test" + i, i);

You'll get a runtime error if the type doesn't match.

Actually, if you try to get the result value in the previous example then you'll get a runtime error in the second loop iteration. This is because you tried to save the return value of a void function.

I know the answers were correct at the time of asking the question - but since people (like me this minute) still happen to find them wondering why their WildFly 10 was behaving differently, I'd like to give an update for the current Hibernate 5.x version:

In the Hibernate 5.2 User Guide it is stated in chapter 11.2. Applying fetch strategies:

The Hibernate recommendation is to statically mark all associations lazy and to use dynamic fetching strategies for eagerness. This is unfortunately at odds with the JPA specification which defines that all one-to-one and many-to-one associations should be eagerly fetched by default. Hibernate, as a JPA provider, honors that default.

So Hibernate as well behaves like Ashish Agarwal stated above for JPA:

OneToMany: LAZY
ManyToOne: EAGER
ManyToMany: LAZY
OneToOne: EAGER

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

I think MAVEN_OPTS would be most appropriate for you. See here: http://maven.apache.org/configure.html

In Unix:

Add the MAVEN_OPTS environment variable to specify JVM properties, e.g. export MAVEN_OPTS="-Xms256m -Xmx512m". This environment variable can be used to supply extra options to Maven.

In Win, you need to set environment variable via the dialogue box

Add ... environment variable by opening up the system properties (WinKey + Pause),... In the same dialog, add the MAVEN_OPTS environment variable in the user variables to specify JVM properties, e.g. the value -Xms256m -Xmx512m. This environment variable can be used to supply extra options to Maven.

There is something fundamentally wrong with what you're trying to do. Binary floating-points values do not have decimal places. You cannot meaningfully round one to a given number of decimal places, because most "round" decimal values simply cannot be represented as a binary fraction. Which is why one should never use float or double to represent money.

So if you want decimal places in your result, that result must either be a String (which you already got with the DecimalFormat), or a BigDecimal (which has a setScale() method that does exactly what you want). Otherwise, the result cannot be what you want it to be.

Read The Floating-Point Guide for more information.

As a Windows 10 user, I followed Dheerendra's answer, and it worked for me one day. The next day, I experienced the issue again, and his fix didn't work. For me, the fix was to update bundler with:

gem update bundler

I believe my version of bundler was more than a few months old.

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

Please set http content type in header and also make sure the server is authenticating CORS. This is how to do it in PHP:

//NOT A TESTED CODE
header('Content-Type: application/json;charset=UTF-8');
header('Access-Control-Allow-Origin: *');
header('Access-Control-Allow-Methods: DELETE, HEAD, GET, OPTIONS, POST, PUT');
header('Access-Control-Allow-Headers: Content-Type, Content-Range, Content-Disposition, Content-Description');
header('Access-Control-Max-Age: 1728000');

Please refer to:

http://www.w3.org/TR/cors/#cross-origin-request-with-preflight-0

How does Access-Control-Allow-Origin header work?

If you are on Windows, you can use the CreateThreadpoolTimer function to schedule a callback without needing to worry about thread management and without blocking the current thread.

template<typename T>
static void __stdcall timer_fired(PTP_CALLBACK_INSTANCE, PVOID context, PTP_TIMER timer)
{
    CloseThreadpoolTimer(timer);
    std::unique_ptr<T> callable(reinterpret_cast<T*>(context));
    (*callable)();
}

template <typename T>
void call_after(T callable, long long delayInMs)
{
    auto state = std::make_unique<T>(std::move(callable));
    auto timer = CreateThreadpoolTimer(timer_fired<T>, state.get(), nullptr);
    if (!timer)
    {
        throw std::runtime_error("Timer");
    }

    ULARGE_INTEGER due;
    due.QuadPart = static_cast<ULONGLONG>(-(delayInMs * 10000LL));

    FILETIME ft;
    ft.dwHighDateTime = due.HighPart;
    ft.dwLowDateTime = due.LowPart;

    SetThreadpoolTimer(timer, &ft, 0 /*msPeriod*/, 0 /*msWindowLength*/);
    state.release();
}

int main()
{
    auto callback = []
    {
        std::cout << "in callback\n";
    };

    call_after(callback, 1000);
    std::cin.get();
}

Check that if your controller class has the [RoutePrefix("somepath")] attribute, that all controller methods also have a [Route()] attribute set.

I've run into this issue as well and was scratching my head for some time.

Singleton scope in Spring means that this bean will be instantiated only once by Spring. In contrast to the prototype scope (new instance each time), request scope (once per request), session scope (once per HTTP session).

Singleton scope has technically nothing to do with the singleton design pattern. You don't have to implement your beans as singletons for them to be put in the singleton scope.

The most voted answer covers most part but I would like to high light use case point of view. Can kafka do that rabbit mq can do, answer is yes but can rabbit mq do everything that kafka does, the answer is no.

The thing that rabbit mq cannot do that makes kafka apart, is distributed message processing. With this now read back the most voted answer and it will make more sense.

To elaborate, take a use case where you need to create a messaging system that has super high throughput for example "likes" in facebook and You have chosen rabbit mq for that. You created an exchange and queue and a consumer where all publishers (in this case FB users) can publish 'likes' messages. Since your throughput is high, you will create multiple threads in consumer to process messages in parallel but you still bounded by the hardware capacity of the machine where consumer is running. Assuming that one consumer is not sufficient to process all messages - what would you do?

• Can you add one more consumer to queue - no you cant do that.
• Can you create a new queue and bind that queue to exchange that publishes 'likes' message, answer is no cause you will have messages processed twice.

That is the core problem that kafka solves. It lets you create distributed partitions (Queue in rabbit mq) and distributed consumer that talk to each other. That ensures your messages in a topic get processed by consumers distributed in various nodes (Machines).

Kafka brokers ensure that messages get load balanced across all partitions of that topic. Consumer group make sure that all consumer talk to each other and message does not get processed twice.

But in real life you will not face this problem unless your throughput is seriously high because rabbit mq can also process data very fast even with one consumer.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

$matches = array();
preg_match('/id=([0-9]+)\?/', $url, $matches);

This is safe for if the format changes. slandau's answer won't work if you ever have any other numbers in the URL.

php.net/preg-match

just use <br>
ex:

<textarea>
blablablabla <br> kakakakakak <br> fafafafafaf 
</textarea>

result:
blablablabla
kakakakakak
fafafafafaf

Many of the answers on this thread work, but it's my understanding if you're trying to do anything dynamic you'll eventually need to call:

[self performSelector:@selector(setNeedsStatusBarAppearanceUpdate)];

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

I would write something like this:

ngOnInit() {
this.routed = this.router.events.map( event => event instanceof NavigationStart )
  .subscribe(() => {
  } );
}

ngOnDestroy() {
this.routed.unsubscribe();
}

You can put a TextBlock inside the label:

<Label> 
  <TextBlock Text="Long Text . . . ." TextWrapping="Wrap" /> 
</Label> 

JavaScript is a very good language to write object oriented web apps. It can support OOP because supports inheritance through prototyping also properties and methods. You can have polymorphism, encapsulation and many sub-classing paradigms.

This error occurs because the default value is true for the Embed Interop Types property of the TestStand API Interop assembly referenced in the new project. To resolve this error, change the value of the Embed Interop Types property to False by following these steps: Select the TestStand Interop Assembly reference in the references section of your project in the Solution Explorer. Find the Embed Interop Types property in the Property Browser, and change the value to False

With pandas version 0.16.1 and up, there is now a DataFrame.sample method built-in:

import pandas

df = pandas.DataFrame(pandas.np.random.random(100))

# Randomly sample 70% of your dataframe
df_percent = df.sample(frac=0.7)

# Randomly sample 7 elements from your dataframe
df_elements = df.sample(n=7)

For either approach above, you can get the rest of the rows by doing:

df_rest = df.loc[~df.index.isin(df_percent.index)]

If you're looking for just the instance variables in the object, this might be useful:

obj.instance_variables.map do |var|
  puts [var, obj.instance_variable_get(var)].join(":")
end

or as a one-liner for copy and pasting:

obj.instance_variables.map{|var| puts [var, obj.instance_variable_get(var)].join(":")}

I know that this is late answer, maybe helpful for researchers

In my case, I had to delete all remotes (there were multiple for some unexplained reason), add the remote again, and commit with -f.

$ git remote
origin
upstream

$ git remote remove upstream
$ git remote remove origin
$ git remote add origin <my origin>
$ git push -u -f origin main

I don't know if the -u flag contributed anything, but it doesn't hurt either.

You can Simply Change Background Color of a View:

var body : some View{


    VStack{

        Color.blue.edgesIgnoringSafeArea(.all)

    }


}

and You can also use ZStack :

var body : some View{


    ZStack{

        Color.blue.edgesIgnoringSafeArea(.all)

    }


}

Not very simple but:

a = [1,1,1,2,2,3]
b = a.group_by {|n| n}.each {|k,v| v.pop [1,3].count(k)}.values.flatten
=> [1, 1, 2, 2]

Also handles the case for multiples in the 'subtrahend':

a = [1,1,1,2,2,3]
b = a.group_by {|n| n}.each {|k,v| v.pop [1,1,3].count(k)}.values.flatten
=> [1, 2, 2]

EDIT: this is more an enhancement combining Norm212 and my answer to make a "functional" solution.

b = [1,1,3].each.with_object( a ) { |del| a.delete_at( a.index( del ) ) }

Put it in a lambda if needed:

subtract = lambda do |minuend, subtrahend|
  subtrahend.each.with_object( minuend ) { |del| minuend.delete_at( minuend.index( del ) ) }
end

then:

subtract.call a, [1,1,3]

// create table
var dt = new System.Data.DataTable("tableName");

// create fields
dt.Columns.Add("field1", typeof(int));
dt.Columns.Add("field2", typeof(string));
dt.Columns.Add("field3", typeof(DateTime));

// insert row values
dt.Rows.Add(new Object[]{
                123456,
                "test",
                DateTime.Now
           });

The docs give a fair indicator of what's required., however requests allow us to skip a few steps:

You only need to install the security package extras (thanks @admdrew for pointing it out)

$ pip install requests[security]

or, install them directly:

$ pip install pyopenssl ndg-httpsclient pyasn1

Requests will then automatically inject pyopenssl into urllib3

If you're on ubuntu, you may run into trouble installing pyopenssl, you'll need these dependencies:

$ apt-get install libffi-dev libssl-dev

To keep the branching clean, you could do this:

git checkout newbranch
git branch newbranch2
git reset --hard <commit Id> # the commit at which you want to merge
git checkout master
git merge newbranch
git checkout newbranch2

This way, newbranch will end where it was merged into master, and you continue working on newbranch2.

I don't know if it's possible to do ranges in awk. You could do a for loop, but you would have to add handling to filter out the columns you don't want. It's probably easier to do this:

awk -F, '{OFS=",";print $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$20,$21,$22,$23,$24,$25,$30,$33}' infile.csv > outfile.csv

something else to consider - and this faster and more concise:

cut -d "," -f1-10,20-25,30-33 infile.csv > outfile.csv

As to the second part of your question, I would probably write a script in perl that knows how to handle header rows, parsing the columns names from stdin or a file and then doing the filtering. It's probably a tool I would want to have for other things. I am not sure about doing in a one liner, although I am sure it can be done.

Just my two cents. If you are using Bootstrap 3 then I would just add an extra style into your own site's stylesheet which controls the text-left style of the control-label.

If you were to add text-left to the label, by default there is another style which overrides this .form-horizontal .control-label. So if you add:

.form-horizontal .control-label.text-left{
    text-align: left;
}

Then the built in text-left style is applied to the label correctly.

SELECT to_char(date_field, 'DD/MM/YYYY')
FROM table

In Python 2:

mylist = ['x', 3, 'b']
print '[%s]' % ', '.join(map(str, mylist))

In Python 3 (where print is a builtin function and not a syntax feature anymore):

mylist = ['x', 3, 'b']
print('[%s]' % ', '.join(map(str, mylist)))

Both return:

[x, 3, b]

This is using the map() function to call str for each element of mylist, creating a new list of strings that is then joined into one string with str.join(). Then, the % string formatting operator substitutes the string in instead of %s in "[%s]".

First list all iptables rules with this command:

iptables -S

it lists like:

-A XYZ -p tcp -m state --state NEW -m tcp --dport 22 -j ACCEPT

Then copy the desired line, and just replace -A with -D to delete that:

iptables -D XYZ -p ...

Search your installation of PhpMyAdmin for a file called Documentation.txt. This describes how to create a file called config.inc.php and how you can configure the username and password.

Since the column may be null in the database, the rs.getString() will throw a NullPointerException()

No.

rs.getString will not throw NullPointer if the column is present in the selected result set (SELECT query columns) For a particular record if value for the 'comumn is null in db, you must do something like this -

String myValue = rs.getString("myColumn");
if (rs.wasNull()) {
    myValue = ""; // set it to empty string as you desire.
}

You may want to refer to wasNull() documentation -

From java.sql.ResultSet
boolean wasNull() throws SQLException;

* Reports whether
* the last column read had a value of SQL <code>NULL</code>.
* Note that you must first call one of the getter methods
* on a column to try to read its value and then call
* the method <code>wasNull</code> to see if the value read was
* SQL <code>NULL</code>.
*
* @return <code>true</code> if the last column value read was SQL
*         <code>NULL</code> and <code>false</code> otherwise
* @exception SQLException if a database access error occurs or this method is 
*            called on a closed result set

{{app.session}} refers to the Session object and not the $_SESSION array. I don't think the $_SESSION array is accessible unless you explicitly pass it to every Twig template or if you do an extension that makes it available.

Symfony2 is object-oriented, so you should use the Session object to set session attributes and not rely on the array. The Session object will abstract this stuff away from you so it is easier to, say, store the session in a database because storing the session variable is hidden from you.

So, set your attribute in the session and retrieve the value in your twig template by using the Session object.

// In a controller
$session = $this->get('session');
$session->set('filter', array(
    'accounts' => 'value',
));

// In Twig
{% set filter = app.session.get('filter') %}
{% set account-filter = filter['accounts'] %}

Hope this helps.

 $('#checkall').on("click",function(){

I kinda disagree with the accepted answer. Sometimes an application architecture doesn't want you to mess with the array id, or makes it inconvenient. For instance, I use CakePHP quite a lot, and a database query returns the primary key as a value in each record, very similar to the above.

Assuming the array is not stupidly large, I would use array_filter. This will create a copy of the array, minus the records you want to remove, which you can assign back to the original array variable.

Although this may seem inefficient it's actually very much in vogue these days to have variables be immutable, and the fact that most php array functions return a new array rather than futzing with the original implies that PHP kinda wants you to do this too. And the more you work with arrays, and realize how difficult and annoying the unset() function is, this approach makes a lot of sense.

Anyway:

$my_array = array_filter($my_array, 
                         function($el) { 
                            return $el["value"]!="Completed" && $el!["value"]!="Marked as Spam"; 
                         });

You can use whatever inclusion logic (eg. your id field) in the embedded function that you want.

With C# 6.0, you can use the nameof operator:

nameof(MyProgram)

There's little need to set all the variables you're setting. CMake sets them to reasonable defaults. You should definitely not modify CMAKE_BINARY_DIR or CMAKE_CACHEFILE_DIR. Treat these as read-only.

First remove the existing problematic cache file from the src directory:

cd src
rm CMakeCache.txt
cd ..

Then remove all the set() commands and do:

cd Compile && rm -rf *
cmake ../src

As long as you're outside of the source directory when running CMake, it will not modify the source directory unless your CMakeList explicitly tells it to do so.

Once you have this working, you can look at where CMake puts things by default, and only if you're not satisfied with the default locations (such as the default value of EXECUTABLE_OUTPUT_PATH), modify only those you need. And try to express them relative to CMAKE_BINARY_DIR, CMAKE_CURRENT_BINARY_DIR, PROJECT_BINARY_DIR etc.

If you look at CMake documentation, you'll see variables partitioned into semantic sections. Except for very special circumstances, you should treat all those listed under "Variables that Provide Information" as read-only inside CMakeLists.

It indicates it couldn't find gcc.exe.

I have a path environment variable set to where MinGW is installed

Maybe you haven't set the path correctly?

echo %path%

shows the path to gcc.exe? Otherwise, compilation is similar to Unix:

gcc filename.c -o filename

If you are using PHP version 7 or higher, try below script,

// Name of the file
$filename = 'sql.sql';
// MySQL host
$mysql_host = 'localhost';
// MySQL username
$mysql_username = 'username';
// MySQL password
$mysql_password = 'password';
// Database name
$mysql_database = 'database';
// Connect to MySQL server
$con = @new mysqli($mysql_host,$mysql_username,$mysql_password,$mysql_database);
// Check connection
if ($con->connect_errno) {
   echo "Failed to connect to MySQL: " . $con->connect_errno;
   echo "<br/>Error: " . $con->connect_error;
}
// Temporary variable, used to store current query
$templine = '';
// Read in entire file
$lines = file($filename);
// Loop through each line
foreach ($lines as $line) {
// Skip it if it's a comment
if (substr($line, 0, 2) == '--' || $line == '')
    continue;
// Add this line to the current segment
$templine .= $line;
// If it has a semicolon at the end, it's the end of the query
if (substr(trim($line), -1, 1) == ';') {
// Perform the query
$con->query($templine) or print('Error performing query \'<strong>' . $templine . '\': ' . $con->error() . '<br /><br />');
    // Reset temp variable to empty
    $templine = '';
}
}
echo "Tables imported successfully";
$con->close($con);

The correct way from hibernate doc:

    Session s = HibernateUtil.getSessionFactory().openSession();
    Transaction tx = null;
    try {

        tx = s.beginTransaction();        

        // here get object
        List<Employee> list = s.createCriteria(Employee.class).list();

        tx.commit();

    } catch (HibernateException ex) {
        if (tx != null) {
            tx.rollback();
        }            
        Logger.getLogger("con").info("Exception: " + ex.getMessage());
        ex.printStackTrace(System.err);
    } finally {
        s.close(); 
    }

HibernateUtil code (can find at Google):

            public class HibernateUtil {

                private static final SessionFactory tmrSessionFactory;
                private static final Ejb3Configuration tmrEjb3Config;

                    try {

                        tmrSessionFactory = new Configuration().configure("tmr.cfg.xml").buildSessionFactory();
                        tmrEjb3Config = new Ejb3Configuration().configure("tmr.cfg.xml");
                        tmrEntityManagerFactory = tmrEjb3Config.buildEntityManagerFactory();

                        Logger.getLogger("app").log(Level.WARN, ex.getMessage());
                        throw new ExceptionInInitializerError(ex);
                    }
                }

                public static SessionFactory getSessionFactory() {
                    return tmrSessionFactory;
                }

                /* getters and setters here */


            }

select a.* , b.Aa , b.Ab, b.Ac from table1 a left join table2 b on a.id=b.id

this should select all columns from table 1 and only the listed columns from table 2 joined by id.

Configure test.ts file inside src folder:

const context = require.context('./', true, /\.spec\.ts$/);

Replace /\.spec\.ts$/ with the file name you want to test. For example: /app.component\.spec\.ts$/

This will run test only for app.component.spec.ts.

Create a shortcut of anaconda prompt onto desktop or taskbar, and then in the properties of that shortcut make sure u modify the last path in "Target:" to the path of ur environment:

C:\Users\BenBouali\Anaconda3\ WILL CHANGE INTO C:\Users\BenBouali\Anaconda3\envs\tensorflow-gpu

preview

and this way u can use that shortcut to open a certain environment when clicking it, you can add it to ur path too and now you'll be able to run it from windows run box by just typing in the name of the shortcut.

On Ubuntu for Windows, I found neither apt-get nor npm versions worked for me. What worked was the script from this comment.

For ease of use, I pasted the whole thing into a script file called install_phantomjs.sh, made it executable (chmod u+x install_phantomjs.sh), and then ran it (./install_phantomjs.sh)

Use SimpleDateFormat

Like this:

event.putExtra("starttime", "12/18/2012");

SimpleDateFormat format = new SimpleDateFormat("MM/dd/yyyy");
Date date = format.parse(bundle.getString("starttime"));

After coming back to my own question after 5 year and seeing so many people found this useful, a little update.

A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.

{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}

or

{% set list1 = variable1.split(';') %}
{% for item in list1 %}
    <p>{{ item }}<p/>
{% endfor %} 

or

{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

In MomentJs We can declare it like :

   const start = moment().format('YYYY-MM-DD 00:00:01');
   const end = moment().format('YYYY-MM-DD 23:59:59');

You can use Date.getTime() function, or the Date object itself which when divided returns the time in milliseconds.

var d = new Date();

d/1000
> 1510329641.84

d.getTime()/1000
> 1510329641.84

isset is intended to be used only for variables and not just values, so isset("foobar") will raise an error. As of PHP 5.5, empty supports both variables and expressions.

So your first question should rather be if isset returns true for a variable that holds an empty string. And the answer is:

$var = "";
var_dump(isset($var));

The type comparison tables in PHP’s manual is quite handy for such questions.

isset basically checks if a variable has any value other than null since non-existing variables have always the value null. empty is kind of the counter part to isset but does also treat the integer value 0 and the string value "0" as empty. (Again, take a look at the type comparison tables.)

A Schema is a collection of database objects which includes logical structures too. It has the name of the user who owns it. A database can have any number of Schema's. One table from a database can appear in two different schemas of same name. A user can view any schema for which they have been assigned select privilege.

To answer your question. I would say it's fairly common for applications to replace spaces in values that will be used in URLs. The reason for this is ussually to avoid the more difficult to read percent (URI) encoding that occurs.

Check out this wikipedia article about Percent-encoding.

From my own experience with webwork, a middleware was stuff between users (the web browser) and the backend database. It was the software that took stuff that users put in (example: orders for iPads, did some magical business logic, i.e. check if there are enough iPads available to fill the order) and updated the backend database to reflect those changes.

If you are just looping through 10k rows in column A, then dump the row into a variant array and then loop through that.

You can then either add the elements to a new array (while adding rows when needed) and using Transpose() to put the array onto your range in one move, or you can use your iterator variable to track which row you are on and add rows that way.

Dim i As Long
Dim varray As Variant

varray = Range("A2:A" & Cells(Rows.Count, "A").End(xlUp).Row).Value

For i = 1 To UBound(varray, 1)
    ' do stuff to varray(i, 1)
Next

Here is an example of how you could add rows after evaluating each cell. This example just inserts a row after every row that has the word "foo" in column A. Not that the "+2" is added to the variable i during the insert since we are starting on A2. It would be +1 if we were starting our array with A1.

Sub test()

Dim varray As Variant
Dim i As Long

varray = Range("A2:A10").Value

'must step back or it'll be infinite loop
For i = UBound(varray, 1) To LBound(varray, 1) Step -1
    'do your logic and evaluation here
    If varray(i, 1) = "foo" Then
       'not how to offset the i variable 
       Range("A" & i + 2).EntireRow.Insert
    End If
Next

End Sub

Jacob Smullyan wrote a utility called pesterfish which uses effbot's ElementTree to convert XML to JSON.

ANDROID_HOME

Deprecated (in Android Studio), use ANDROID_SDK_ROOT instead.

ANDROID_SDK_ROOT

Installation directory of Android SDK package.

Example: C:\AndroidSDK or /usr/local/android-sdk/

ANDROID_NDK_ROOT

Installation directory of Android NDK package. (WITHOUT ANY SPACE)

Example: C:\AndroidNDK or /usr/local/android-ndk/

ANDROID_SDK_HOME

Location of SDK related data/user files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_EMULATOR_HOME

Location of emulator-specific data files.

Example: C:\Users\<USERNAME>\.android\ or ~/.android/

ANDROID_AVD_HOME

Location of AVD-specific data files.

Example: C:\Users\<USERNAME>\.android\avd\ or ~/.android/avd/

JDK_HOME and JAVA_HOME

Installation directory of JDK (aka Java SDK) package.

Note: This is used to run Android Studio(and other Java-based applications). Actually when you run Android Studio, it checks for JDK_HOME then JAVA_HOME environment variables to use.

You can use this

string.strip().split(":")

LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.

You have a lot of reading ahead of you. From compiler errors through exception handling, threading and thread interruptions. But this will do what you want:

try {
    Thread.sleep(1000);                 //1000 milliseconds is one second.
} catch(InterruptedException ex) {
    Thread.currentThread().interrupt();
}

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

This will work too

my_country_code="green"
x="country"

eval z='$'my_"$x"_code
echo $z                 ## o/p: green

In your case

eval final_val='$'magic_way_to_define_magic_variable_"$1"
echo $final_val

Taken from http://www.dotnetspider.com/resources/189-AutoPostBack-What-How-works.aspx:

Autopostback is the mechanism by which the page will be posted back to the server automatically based on some events in the web controls. In some of the web controls, the property called auto post back, if set to true, will send the request to the server when an event happens in the control.

Whenever we set the autopostback attribute to true on any of the controls, the .NET framework will automatically insert a few lines of code into the HTML generated to implement this functionality.

1. A JavaScript method with name __doPostBack (eventtarget, eventargument)
2. Two hidden variables with name __EVENTTARGET and __EVENTARGUMENT
3. OnChange JavaScript event to the control

CommonJS modules allow two ways to define exported properties. In either case you are returning an Object/Function. Because functions are first class citizens in JavaScript they to can act just like Objects (technically they are Objects). That said your question about using the new keywords has a simple answer: Yes. I'll illustrate...

Module exports

You can either use the exports variable provided to attach properties to it. Once required in another module those assign properties become available. Or you can assign an object to the module.exports property. In either case what is returned by require() is a reference to the value of module.exports.

A pseudo-code example of how a module is defined:

var theModule = {
  exports: {}
};

(function(module, exports, require) {

  // Your module code goes here

})(theModule, theModule.exports, theRequireFunction);

In the example above module.exports and exports are the same object. The cool part is that you don't see any of that in your CommonJS modules as the whole system takes care of that for you all you need to know is there is a module object with an exports property and an exports variable that points to the same thing the module.exports does.

Require with constructors

Since you can attach a function directly to module.exports you can essentially return a function and like any function it could be managed as a constructor (That's in italics since the only difference between a function and a constructor in JavaScript is how you intend to use it. Technically there is no difference.)

So the following is perfectly good code and I personally encourage it:

// My module
function MyObject(bar) {
  this.bar = bar;
}

MyObject.prototype.foo = function foo() {
  console.log(this.bar);
};

module.exports = MyObject;

// In another module:
var MyObjectOrSomeCleverName = require("./my_object.js");
var my_obj_instance = new MyObjectOrSomeCleverName("foobar");
my_obj_instance.foo(); // => "foobar"

Require for non-constructors

Same thing goes for non-constructor like functions:

// My Module
exports.someFunction = function someFunction(msg) {
  console.log(msg);
}

// In another module
var MyModule = require("./my_module.js");
MyModule.someFunction("foobar"); // => "foobar"

Using Laravel Eloquent you can get one row using first() method,

it returns first row of table if where() condition is not found otherwise it gives the first matched row of given criteria.

Syntax:

Model::where('fieldname',$value)->first();

Example:

$user = User::where('email',$email)->first(); 
//OR
//$user = User::whereEmail($email)->first();

To understand this peculiar behavior of hibernate, it is important to understand a few hibernate concepts -

Hibernate Object States

Transient - An object is in transient status if it has been instantiated and is still not associated with a Hibernate session.

Persistent - A persistent instance has a representation in the database and an identifier value. It might just have been saved or loaded, however, it is by definition in the scope of a Session.

Detached - A detached instance is an object that has been persistent, but its Session has been closed.

http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/objectstate.html#objectstate-overview

Transaction Write-Behind

The next thing to understand is 'Transaction Write behind'. When objects attached to a hibernate session are modified they are not immediately propagated to the database. Hibernate does this for at least two different reasons.

• To perform batch inserts and updates.
• To propagate only the last change. If an object is updated more than once, it still fires only one update statement.

http://learningviacode.blogspot.com/2012/02/write-behind-technique-in-hibernate.html

First Level Cache

Hibernate has something called 'First Level Cache'. Whenever you pass an object to save(), update() or saveOrUpdate(), and whenever you retrieve an object using load(), get(), list(), iterate() or scroll(), that object is added to the internal cache of the Session. This is where it tracks changes to various objects.

Hibernate Intercepters and Object Lifecycle Listeners -

The Interceptor interface and listener callbacks from the session to the application, allow the application to inspect and/or manipulate properties of a persistent object before it is saved, updated, deleted or loaded. http://docs.jboss.org/hibernate/orm/4.0/hem/en-US/html/listeners.html#d0e3069

This section Updated

Cascading

Hibernate allows applications to define cascade relationships between associations. For example, 'cascade-delete' from parent to child association will result in deletion of all children when a parent is deleted.

So, why are these important.

To be able to do transaction write-behind, to be able to track multiple changes to objects (object graphs) and to be able to execute lifecycle callbacks hibernate needs to know whether the object is transient/detached and it needs to have the object in it's first level cache before it makes any changes to the underlying object and associated relationships.

That's why hibernate (sometimes) issues a 'SELECT' statement to load the object (if it's not already loaded) in to it's first level cache before it makes changes to it.

Why does hibernate issue the 'SELECT' statement only sometimes?

Hibernate issues a 'SELECT' statement to determine what state the object is in. If the select statement returns an object, the object is in detached state and if it does not return an object, the object is in transient state.

Coming to your scenario -

Delete - The 'Delete' issued a SELECT statement because hibernate needs to know if the object exists in the database or not. If the object exists in the database, hibernate considers it as detached and then re-attches it to the session and processes delete lifecycle.

Update - Since you are explicitly calling 'Update' instead of 'SaveOrUpdate', hibernate blindly assumes that the object is in detached state, re-attaches the given object to the session first level cache and processes the update lifecycle. If it turns out that the object does not exist in the database contrary to hibernate's assumption, an exception is thrown when session flushes.

SaveOrUpdate - If you call 'SaveOrUpdate', hibernate has to determine the state of the object, so it uses a SELECT statement to determine if the object is in Transient/Detached state. If the object is in transient state, it processes the 'insert' lifecycle and if the object is in detached state, it processes the 'Update' lifecycle.

You'll need to declare constructors in each of the derived classes, and then call the base class constructor from the initializer list:

class D : public A
{
public:
    D(const string &val) : A(0) {}
    D( int val ) : A( val ) {}
};

D variable1( "Hello" );
D variable2( 10 );

C++11 allows you to use the using A::A syntax you use in your decleration of D, but C++11 features aren't supported by all compilers just now, so best to stick with the older C++ methods until this feature is implemented in all the compilers your code will be used with.

Object to array

$array = (array) $players_Obj;  

$object = new StdClass;
$object->foo = 1;
$object->bar = 2;

var_dump( (array) $object );

Output:

array(2) {
    'foo' => int(1)
    'bar' => int(2)
}

Perform a click on the link to the tab anchor whenever the page is ready i.e.

$('a[href="' + window.location.hash + '"]').trigger('click');

Or in vanilla JavaScript

document.querySelector('a[href="' + window.location.hash + '"]').click();

You can use 'required' http://jsbin.com/atefuq/1/edit

<form action="login.php" method="post">
    <label>Login Name:</label>
    <input required type="text" name="email" id="log" />
    <label>Password:</label>
    <input required type="password" name="password" id="pwd" />
    <input  required type="submit" name="submit" value="Login" />
</form>

You misread the documentation. You need to do two things:

1. Quote each key and value from your dictionary, and
2. Encode those into a URL

Luckily urllib.parse.urlencode does both those things in a single step, and that's the function you should be using.

from urllib.parse import urlencode, quote_plus

payload = {'username':'administrator', 'password':'xyz'}
result = urlencode(payload, quote_via=quote_plus)
# 'password=xyz&username=administrator'

In my case, basically I needed to restart my Windows.

Run apt-get install build-essential on your system.

This package depends on other packages considered to be essential for builds and will install them. If you find you have to build packages, this can be helpful to avoid piecemeal resolution of dependencies.

See this page for more info.

For me this was resolved by adding an explicit default constructor

public MyClassName (){}

More information would be useful.

But the simplest form:

#include <iostream>
#include <sstream>
#include <fstream>
#include <string>

int main()
{
    std::ifstream  data("plop.csv");

    std::string line;
    while(std::getline(data,line))
    {
        std::stringstream  lineStream(line);
        std::string        cell;
        while(std::getline(lineStream,cell,','))
        {
            // You have a cell!!!!
        }
    }
 }

Also see this question: CSV parser in C++

In javascript there are no block-level scopes only function-level scopes:

Read this article about javaScript Scoping and Hoisting.

See how I debugged your code:

var deferred = $q.defer();
deferred.count = i;

console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects

// some code

.success(function(data){
   console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
   deferred.resolve(data);
})

• When you write var deferred= $q.defer(); inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop.
• With each loop, the last deferred is overriding the previous one, there is no block-level scope to save a reference to that object.
• When asynchronous callbacks (success / error) are invoked, they reference only the last deferred object and only it gets resolved, so $q.all is never resolved because it still waits for other deferred objects.
• What you need is to create an anonymous function for each item you iterate.
• Since functions do have scopes, the reference to the deferred objects are preserved in a closure scope even after functions are executed.
• As #dfsq commented: There is no need to manually construct a new deferred object since $http itself returns a promise.

Solution with angular.forEach:

Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = [];

    angular.forEach(questions , function(question) {

        var promise = $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

        promises.push(promise);

    });

    return $q.all(promises);
}

My favorite way is to use Array#map:

Here is a demo plunker: http://plnkr.co/edit/KYeTWUyxJR4mlU77svw9?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = questions.map(function(question) {

        return $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

    });

    return $q.all(promises);
}

You can refer to https://curl.haxx.se/docs/http-cookies.html for a complete tutorial of how to work with cookies. You can use

curl -c /path/to/cookiefile http://yourhost/

to write to a cookie file and start engine and to use cookie you can use

curl -b /path/to/cookiefile  http://yourhost/

to read cookies from and start the cookie engine, or if it isn't a file it will pass on the given string.

Below command can be used for finding both package and current Activity name. Found this very useful command to quickly fetch these two information about an app especially when developing tests with Appium.

adb shell dumpsys window windows | grep -E 'mCurrentFocus'

Response of this command contains both package name and current Activity. For example: in following "com.android.contacts" is the package and "com.android.contacts.activities.TwelveKeyDialer" is current Activity launched on the phone which is connected via adb.

mCurrentFocus=Window{2089af8 u0 com.android.contacts/com.android.contacts.activities.TwelveKeyDialer}

Here is a slightly different implementation of an AJAX cache as in ehynd's answer.

As noted in fortuneRice's follow-up question, ehynd's implementation didn't actually prevent multiple identical requests if the requests were performed before one of them had returned. That is,

for (var i=0; i<3; i++) {
    getData("xxx");
}

will most likely result in 3 AJAX requests if the result for "xxx" has not already been cached before.

This can be solved by caching the request's Deferreds instead of the result:

var cache = {};

function getData( val ){

    // Return a promise from the cache (if available)
    // or create a new one (a jqXHR object) and store it in the cache.
    var promise = cache[val];
    if (!promise) {
        promise = $.ajax('/foo/', {
            data: { value: val },
            dataType: 'json'
        });
        cache[val] = promise;
    }
    return promise;
}

$.when(getData('foo')).then(function(resp){
    // do something with the response, which may
    // or may not have been retreived using an
    // XHR request.
});

Many thanks to @Ciro Santilli answer! I found that his choice for boundary is quite "unhappy" because all of thoose hyphens: in fact, as @Fake Name commented, when you are using your boundary inside request it comes with two more hyphens on front:

Example:

POST / HTTP/1.1
HOST: host.example.com
Cookie: some_cookies...
Connection: Keep-Alive
Content-Type: multipart/form-data; boundary=12345

--12345
Content-Disposition: form-data; name="sometext"

some text that you wrote in your html form ...
--12345
Content-Disposition: form-data; name="name_of_post_request" filename="filename.xyz"

content of filename.xyz that you upload in your form with input[type=file]
--12345
Content-Disposition: form-data; name="image" filename="picture_of_sunset.jpg"

content of picture_of_sunset.jpg ...
--12345--

I found on this w3.org page that is possible to incapsulate multipart/mixed header in a multipart/form-data, simply choosing another boundary string inside multipart/mixed and using that one to incapsulate data. At the end, you must "close" all boundary used in FILO order to close the POST request (like:

POST / HTTP/1.1
...
Content-Type: multipart/form-data; boundary=12345

--12345
Content-Disposition: form-data; name="sometext"

some text sent via post...
--12345
Content-Disposition: form-data; name="files"
Content-Type: multipart/mixed; boundary=abcde

--abcde
Content-Disposition: file; file="picture.jpg"

content of jpg...
--abcde
Content-Disposition: file; file="test.py"

content of test.py file ....
--abcde--
--12345--

Take a look at the link above.

Alternatively you can just create a tunnel to the server:

ssh -i <your_key> <user@server-instance> -L 8888:127.0.0.1:8888

Then just open 127.0.0.1:8888 in your browser.

You also omit the -i <your_key> if you don't have an identity_file.

The quickest way to do this is using SWIG.

Example from SWIG tutorial:

/* File : example.c */
int fact(int n) {
    if (n <= 1) return 1;
    else return n*fact(n-1);
}

Interface file:

/* example.i */
%module example
%{
/* Put header files here or function declarations like below */
extern int fact(int n);
%}

extern int fact(int n);

Building a Python module on Unix:

swig -python example.i
gcc -fPIC -c example.c example_wrap.c -I/usr/local/include/python2.7
gcc -shared example.o example_wrap.o -o _example.so

Usage:

>>> import example
>>> example.fact(5)
120

Note that you have to have python-dev. Also in some systems python header files will be in /usr/include/python2.7 based on the way you have installed it.

From the tutorial:

SWIG is a fairly complete C++ compiler with support for nearly every language feature. This includes preprocessing, pointers, classes, inheritance, and even C++ templates. SWIG can also be used to package structures and classes into proxy classes in the target language — exposing the underlying functionality in a very natural manner.

Don't get the request stream, quite simply. GET requests don't usually have bodies (even though it's not technically prohibited by HTTP) and WebRequest doesn't support it - but that's what calling GetRequestStream is for, providing body data for the request.

Given that you're trying to read from the stream, it looks to me like you actually want to get the response and read the response stream from that:

WebRequest request = WebRequest.Create(get.AbsoluteUri + args);
request.Method = "GET";
using (WebResponse response = request.GetResponse())
{
    using (Stream stream = response.GetResponseStream())
    {
        XmlTextReader reader = new XmlTextReader(stream);
        ...
    }
}

1. Connect your iPhone to your Mac via USB.

2. Go to Network Utility (cmd+space and type "network utility")

3. Go to the "Info" tab

4. Click on the drop down menu that says "Wi-Fi" and select "iPhone USB" as shown here:

   

5. You'll find an IP address like "xxx.xxx.xx.xx" or similar. Open Safari browser on your iPhone and enter IP_address:port_number

   Example: 169.254.72.86:3000

[NOTE: If the IP address field is blank, make sure your iPhone is connected via USB, quit Network Utility, open it again and check for the IP address.]

YES YOU CAN.

In your stored procedure, you fill the table @tbRetour.

At the very end of your stored procedure, you write:

SELECT * FROM @tbRetour 

To execute the stored procedure, you write:

USE [...]
GO

DECLARE @return_value int

EXEC @return_value = [dbo].[getEnregistrementWithDetails]
@id_enregistrement_entete = '(guid)'

It happens when we are trying to push to remote repository but has created a new file on remote which has not been pulled yet, let say Readme. In that case as the error says

git rejects the update

as we have not taken updated remote in our local environment. So Take pull first from remote

git pull

It will update your local repository and add a new Readme file. Then Push updated changes to remote

git push origin master

this is a basic step for learn:

How to delete row from gridview?

You can check out libvideo. It's much more up-to-date than YoutubeExtractor, and is fast and clean to use.

You have 2 options :

1. Create a third method that wrap both methods. Advantage here is that you put less logic in your template.

2. Otherwise if you want to add 2 calls in ng-click you can add ';' after edit($index) like this

   ng-click="edit($index); open()"

I have just experienced this issue in one of my MySQL db's and I looked at the phpMyAdmin answer here. However the best way I fixed it in phpMyAdmin was in the affected table, drop the id column and make a fresh/new id column (adding A-I -autoincrement-). This restored my table id correctly-simples! Hope that helps (no MySQL code needed-I hope to learn to use that but later!) anyone else with this problem.

try use keyup.enter or keydown.enter

  <button type="submit" (keyup.enter)="search(...)">Search</button>

I would suggest not to use seaborn pointplot for plotting. This makes things unnecessarily complicated.
Instead use matplotlib plot_date. This allows to set labels to the plots and have them automatically put into a legend with ax.legend().

import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
import numpy as np

date = pd.date_range("2017-03", freq="M", periods=15)
count = np.random.rand(15,4)
df1 = pd.DataFrame({"date":date, "count" : count[:,0]})
df2 = pd.DataFrame({"date":date, "count" : count[:,1]+0.7})
df3 = pd.DataFrame({"date":date, "count" : count[:,2]+2})

f, ax = plt.subplots(1, 1)
x_col='date'
y_col = 'count'

ax.plot_date(df1.date, df1["count"], color="blue", label="A", linestyle="-")
ax.plot_date(df2.date, df2["count"], color="red", label="B", linestyle="-")
ax.plot_date(df3.date, df3["count"], color="green", label="C", linestyle="-")

ax.legend()

plt.gcf().autofmt_xdate()
plt.show()

sns.pointplot(ax=ax,x=x_col,y=y_col,data=df1,color='blue')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df2,color='green')
sns.pointplot(ax=ax,x=x_col,y=y_col,data=df3,color='red')

ax.legend(handles=ax.lines[::len(df1)+1], labels=["A","B","C"])

ax.set_xticklabels([t.get_text().split("T")[0] for t in ax.get_xticklabels()])
plt.gcf().autofmt_xdate()

plt.show()

There are 3 basic commands to compare files in unix:

1. cmp : This command is used to compare two files byte by byte and as any mismatch occurs,it echoes it on the screen.if no mismatch occurs i gives no response. syntax:$cmp file1 file2.

2. comm : This command is used to find out the records available in one but not in another

3. diff

Because you cannot have a general algorithm for every locale, no. You have to implement your own algorithm for every locale that you are supporting.

** EDIT **

Just for the heck of it, I played around until I got this class. It cannot display Long.MIN_VALUE because of bit restrictions... but I presume it could be modified and change long value types to double for decimal or even bigger numbers It can display any numbers up to 66 digits and 26 decimals using a string representation of the number. You may add more ScaleUnit for more decimals...

First install TortoiseSVN. During installation follow this steps

1.Run the the TortoiseSVN Installer.

2.If you have already installed svn, "Select the option to Modify".

3.select the check box "Install Command line client tools on to the local harddrive".

4.Add C:\Program Files\TortoiseSVN\bin to your Path environment variable or press CTRL+ALT+S in android studio. Then go to "Version Control"-> Subversion -> General -> Check the Checkbox "use commmand line client" and set the path to C:\Program Files\TortoiseSVN\bin\svn.exe

5.Restart IntelliJ.

In Android studio1.5 version when you try to add the file in your project,
android studio will ask for a pop like "schedule for Addition"
to subversion?. select the check box (Remember, don't ask again) and click "yes". 
After this whatever the file you add or remove to your project it will automatically
synced to your svn repository. suppose if you didn't get that dialog, but you want to
add the newly added .png or xml file to svn means you can manually select those files 
which you have added (the newly added file will be in red color) right click 
on that file -> subversion -> Add to VCS or simply select the file and use (CTRL+ALT+A).

In the image green color(logo_actionbar) represents to file was already added to svn, red represents yet to add in svn. cool..!

If you want to change the "Schedule for Addition" setting means, Go to Settings -> Version Control -> Confirmation -> When files are created
Choose Show options before adding to version control

Shift-Alt-J is a useful keyboard shortcut in Eclipse for creating Javadoc comment templates.

Invoking the shortcut on a class, method or field declaration will create a Javadoc template:

public int doAction(int i) {
    return i;
}

Pressing Shift-Alt-J on the method declaration gives:

/**
 * @param i
 * @return
 */
public int doAction(int i) {
    return i;
}

Problem

The trim() method removes whitespace from both sides of a string.

Source

Solution

You can use a Javascript replace method to remove white space like

"hello world".replace(/\s/g, "");

Example

var out = "hello world".replace(/\s/g, "");_x000D_
console.log(out);

While @tymeJV gave a correct answer, the way to do this to be inline with angular would be:

ng-click="hidePrefs()"

and then in your controller:

$scope.hidePrefs = function() {  
  $scope.prefs = false;
}

Sometimes you can just do 'Window -> Reset Window Layout', and that'll work :)

In my view the most realistic scenario is when tasks have a heavy operation to complete. Shivprasad's approach focuses more on object creation/memory allocation than on computing itself. I made a research calling the following method:

public static double SumRootN(int root)
{
    double result = 0;
    for (int i = 1; i < 10000000; i++)
        {
            result += Math.Exp(Math.Log(i) / root);
        }
        return result; 
}

Execution of this method takes about 0.5sec.

I called it 200 times using Parallel:

Parallel.For(0, 200, (int i) =>
{
    SumRootN(10);
});

Then I called it 200 times using the old-fashioned way:

List<Task> tasks = new List<Task>() ;
for (int i = 0; i < loopCounter; i++)
{
    Task t = new Task(() => SumRootN(10));
    t.Start();
    tasks.Add(t);
}

Task.WaitAll(tasks.ToArray()); 

First case completed in 26656ms, the second in 24478ms. I repeated it many times. Everytime the second approach is marginaly faster.

You can set a default value at creation time like:

CREATE TABLE Persons (
ID int NOT NULL,
LastName varchar(255) NOT NULL,
FirstName varchar(255),
Age int,
Married boolean DEFAULT false);

You need a development provisioning profile on your build machine. Apps can run on the simulator without a profile, but they are required to run on an actual device.

If you open the project in Xcode, it may automatically set up provisioning for you. Otherwise you will have to create go to the iOS Dev Center and create a profile.

I had the same issue with Angular 7. Just went through the following steps and error was solved.

1). Delete your node_modules folder and package-lock.json file.

2). Run npm install command.

3). Run npm audit fix command.

Here is a similar solution which I think is more efficient in building up the list of %s strings in the SQL:

Use the list_of_ids directly:

format_strings = ','.join(['%s'] * len(list_of_ids))
cursor.execute("DELETE FROM foo.bar WHERE baz IN (%s)" % format_strings,
                tuple(list_of_ids))

That way you avoid having to quote yourself, and avoid all kinds of sql injection.

Note that the data (list_of_ids) is going directly to mysql's driver, as a parameter (not in the query text) so there is no injection. You can leave any chars you want in the string, no need to remove or quote chars.

The best way in my opinion is Reflection as others have recommended. Here's a sample that evaluates each local field for null. If it finds one that is not null, method will return false.

public class User {

    String id = null;
    String name = null;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public boolean isNull() {
        Field fields[] = this.getClass().getDeclaredFields();
        for (Field f : fields) {
            try {
                Object value = f.get(this);
                if (value != null) {
                    return false;
                }
            }
            catch (IllegalArgumentException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }


        }
        return true;

    }

    public static void main(String args[]) {
        System.out.println(new User().isNull());
    }
}

According to the documentation there are several ways to do the inlining.
The right way you must choose based on the situation.

1) Simply put the variable from server to javascript :

<script th:inline="javascript">
/*<![CDATA[*/

var message = [[${message}]];
alert(message);

/*]]>*/
</script>

2) Combine javascript variables with server side variables, e.g. you need to create link for requesting inside the javascript:

<script th:inline="javascript">
        /*<![CDATA[*/
        function sampleGetByJquery(v) {
            /*[+
            var url = [[@{/my/get/url(var1=${#httpServletRequest.getParameter('var1')})}]] 
                      + "&var2="+v;
             +]*/
            $("#myPanel").load(url, function() {});
        }
        /*]]>*/
        </script>

The one situation I can't resolve - then I need to pass javascript variable inside the Java method calling inside the template (it's impossible I guess).

For the record, and excluding the time that it takes:

<?php
echo "<hr>First:<br>";
$x = str_repeat('x', 80000);
echo memory_get_usage() . "<br>\n";      
echo memory_get_peak_usage() . "<br>\n"; 
echo "<hr>Unset:<br>";
unset($x);
$x = str_repeat('x', 80000);
echo memory_get_usage() . "<br>\n";      
echo memory_get_peak_usage() . "<br>\n"; 
echo "<hr>Null:<br>";
$x=null;
$x = str_repeat('x', 80000);
echo memory_get_usage() . "<br>\n";      
echo memory_get_peak_usage() . "<br>\n";

echo "<hr>function:<br>";
function test() {
    $x = str_repeat('x', 80000);
}
echo memory_get_usage() . "<br>\n";      
echo memory_get_peak_usage() . "<br>\n"; 

echo "<hr>Reasign:<br>";
$x = str_repeat('x', 80000);
echo memory_get_usage() . "<br>\n";      
echo memory_get_peak_usage() . "<br>\n"; 

It returns

First:
438296
438352
Unset:
438296
438352
Null:
438296
438352
function:
438296
438352
Reasign:
438296
520216 <-- double usage.

Conclusion, both null and unset free memory as expected (not only at the end of the execution). Also, reassigning a variable holds the value twice at some point (520216 versus 438352)

If you want to have bare run command in gdb to execute your program with redirections and arguments, you can use set args:

% gdb ./a.out
(gdb) set args arg1 arg2 <file
(gdb) run

I was unable to achieve the same behaviour with --args parameter, gdb fiercely escapes the redirections, i.e.

% gdb --args echo 1 2 "<file"
(gdb) show args
Argument list to give program being debugged when it is started is "1 2 \<file".
(gdb) run
...
1 2 <file
...

This one actually redirects the input of gdb itself, not what we really want here

% gdb --args echo 1 2 <file
zsh: no such file or directory: file

That is because you are in 'Interactive Mode' where php evaluates everything you type. To see the end result, you do 'ctrl+z' and Enter. You should see the evaluated result now :)

p.s. run the cmd as Administrator!

Use the UITableViewDataSource method

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

Environment.NewLine will return the newline character for the corresponding platform in which your code is running

you will find this very useful when you deploy your code in linux on the Mono framework

The lack of an exponential operator for C# was a big annoyance for us when looking for a new language to convert our calculation software to from the good ol' vb6.

I'm glad we went with C# but it still annoys me whenever I'm writing a complex equation including exponents. The Math.Pow() method makes equations quite hard to read IMO.

Our solution was to create a special DoubleX class where we override the ^-operator (see below)

This works fairly well as long as you declare at least one of the variables as DoubleX:

DoubleX a = 2;
DoubleX b = 3;

Console.WriteLine($"a = {a}, b = {b}, a^b = {a ^ b}");

or use an explicit converter on standard doubles:

double c = 2;
double d = 3;

Console.WriteLine($"c = {c}, d = {d}, c^d = {c ^ (DoubleX)d}");     // Need explicit converter

One problem with this method though is that the exponent is calculated in the wrong order compared to other operators. This can be avoided by always putting an extra ( ) around the operation which again makes it a bit harder to read the equations:

DoubleX a = 2;
DoubleX b = 3;

Console.WriteLine($"a = {a}, b = {b}, 3+a^b = {3 + a ^ b}");        // Wrong result
Console.WriteLine($"a = {a}, b = {b}, 3+a^b = {3 + (a ^ b)}");      // Correct result

I hope this can be of help to others who uses a lot of complex equations in their code, and maybe someone even has an idea of how to improve this method?!

DoubleX class:

using System;

namespace ExponentialOperator
{
    /// <summary>
    /// Double class that uses ^ as exponential operator
    /// </summary>

OK, here is one solution I have come up with which is pretty messed up.

I put the full label text into the div using the fontFamily label attribute. Then I use querySelectorAll to match the resulting style attributes to pull out the refs and rewrite the tags once the map has loaded:

var label = "A123";
var marker = new google.maps.Marker({
  position: latLon,
  label: {
    text: label,
    // Add in the custom label here
    fontFamily: 'Roboto, Arial, sans-serif, custom-label-' + label
  },
  map: map,
  icon: {
    path: 'custom icon path',
    fillColor: '#000000',
    labelOrigin: new google.maps.Point(26.5, 20),
    anchor: new google.maps.Point(26.5, 43), 
    scale: 1
  }
});

google.maps.event.addListener(map, 'idle', function() {
  var labels = document.querySelectorAll("[style*='custom-label']")
  for (var i = 0; i < labels.length; i++) {
    // Retrieve the custom labels and rewrite the tag content
    var matches = labels[i].getAttribute('style').match(/custom-label-(A\d\d\d)/);
    labels[i].innerHTML = matches[1];
  }
});

This seems pretty brittle. Are there any approaches which are less awful?

I tend to version my framework then apply the version number to script and style paths

<cfset fw.version = '001' />
<script src="/scripts/#fw.version#/foo.js"/>

Use empty form tag before your nested form

Tested and Worked on Firefox, Chrome

Not Tested on I.E.

<form name="mainForm" action="mainAction">
  <form></form>
  <form name="subForm"  action="subAction">
  </form>
</form>

EDIT by @adusza: As the commenters pointed out, the above code does not result in nested forms. However, if you add div elements like below, you will have subForm inside mainForm, and the first blank form will be removed.

<form name="mainForm" action="mainAction">
  <div>
      <form></form>
      <form name="subForm"  action="subAction">
      </form>
  </div>
</form>

In your situation, you can extract the desired data with:

a[:, -z]

"-z" is the logical negation of the boolean array "z". This is the same as:

a[:, logical_not(z)]

You can encapsulate your block of code with a try ... catch statement, and when you run your code, if the column doesn't exist it will throw an exception. You can then figure out what specific exception it throws and have it handle that specific exception in a different way if you so desire, such as returning "Column Not Found".

I need to change datatype of multiple fields in the collection, so I used the following to make multiple data type changes in the collection of documents. Answer to an old question but may be helpful for others.

db.mycoll.find().forEach(function(obj) { 

    if (obj.hasOwnProperty('phone')) {
        obj.phone = "" + obj.phone;  // int or longint to string
    }

    if (obj.hasOwnProperty('field-name')) {
     obj.field-name = new NumberInt(obj.field-name); //string to integer
    }

    if (obj.hasOwnProperty('cdate')) {
        obj.cdate = new ISODate(obj.cdate); //string to Date
    }

    db.mycoll.save(obj); 
});

Possible with HTML5.

There are static libraries (LIB) and dynamic libraries (DLL) - but note that .LIB files can be either static libraries (containing object files) or import libraries (containing symbols to allow the linker to link to a DLL).

Libraries are used because you may have code that you want to use in many programs. For example if you write a function that counts the number of characters in a string, that function will be useful in lots of programs. Once you get that function working correctly you don't want to have to recompile the code every time you use it, so you put the executable code for that function in a library, and the linker can extract and insert the compiled code into your program. Static libraries are sometimes called 'archives' for this reason.

Dynamic libraries take this one step further. It seems wasteful to have multiple copies of the library functions taking up space in each of the programs. Why can't they all share one copy of the function? This is what dynamic libraries are for. Rather than building the library code into your program when it is compiled, it can be run by mapping it into your program as it is loaded into memory. Multiple programs running at the same time that use the same functions can all share one copy, saving memory. In fact, you can load dynamic libraries only as needed, depending on the path through your code. No point in having the printer routines taking up memory if you aren't doing any printing. On the other hand, this means you have to have a copy of the dynamic library installed on every machine your program runs on. This creates its own set of problems.

As an example, almost every program written in 'C' will need functions from a library called the 'C runtime library, though few programs will need all of the functions. The C runtime comes in both static and dynamic versions, so you can determine which version your program uses depending on particular needs.

Since this is an open-ended question, I will just give you an idea of how I would go about implementing something like this myself.

<span class="inputname">
    Project Images:
    <a href="#" class="add_project_file">
        <img src="images/add_small.gif" border="0" />
    </a>
</span>

<ul class="project_images">
    <li><input name="upload_project_images[]" type="file" /></li>
</ul>

Wrapping the file inputs inside li elements allows to easily remove the parent of our 'remove' links when clicked. The jQuery to do so is close to what you have already:

// Add new input with associated 'remove' link when 'add' button is clicked.
$('.add_project_file').click(function(e) {
    e.preventDefault();

    $(".project_images").append(
        '<li>'
      + '<input name="upload_project_images[]" type="file" class="new_project_image" /> '
      + '<a href="#" class="remove_project_file" border="2"><img src="images/delete.gif" /></a>'
      + '</li>');
});

// Remove parent of 'remove' link when link is clicked.
$('.project_images').on('click', '.remove_project_file', function(e) {
    e.preventDefault();

    $(this).parent().remove();
});

c#: "\"", thus s.Replace("\"", "")

vb/vbs/vb.net: "" thus s.Replace("""", "")

Your indentation is broken. This should fix it:

import sys

def hello(a,b):
    print 'hello and thats your sum:'
    sum=a+b
    print sum

if __name__ == "__main__":
    hello(sys.argv[1], sys.argv[2])

Obviously, if you put the if __name__ statement inside the function, it will only ever be evaluated if you run that function. The problem is: the point of said statement is to run the function in the first place.

//In .net MVC
[OutputCache(NoStore = true, Duration = 0, VaryByParam = "*")]
public ActionResult FareListInfo(long id)
{
}

// In .net webform
<%@ OutputCache NoStore="true" Duration="0" VaryByParam="*" %>

In our particular case, we use Stash as our remote Git repository. We tried all the previous answers and nothing was working. We ended up having to do the following:

git branch –D branch-name (delete from local)
git push origin :branch-name (delete from remote)

Then when users went to pull changes, they needed to do the following:

git fetch -p

Add the following css to your html and try changing the top, right, bottom, left values.

.modal {
   position: absolute;
   top: 10px;
   right: 100px;
   bottom: 0;
   left: 0;
   z-index: 10040;
   overflow: auto;
   overflow-y: auto;
}

I consider state to be for view only information and data that should persist beyond the view state is better stored as props. URL params are useful when you want to be able to link to a page or share the URL deep in to the app but otherwise clutter the address bar.

Take a look at Redux-Persist (if you're using redux) https://github.com/rt2zz/redux-persist

If you are using ggplot2 to generate a figure, then a ggsave(file="name.eps") will also work.

var last = array.slice(-1)[0];

I find slice at -1 useful for getting the last element (especially of an array of unknown length) and the performance is much better than calculating the length less 1.

Mozilla Docs on Slice

Performance of the various methods for selecting last array element

Assuming that your table name is city and your existing Primary Key is pk_city, you should be able to do the following:

ALTER TABLE city
DROP CONSTRAINT pk_city;

ALTER TABLE city
ADD CONSTRAINT pk_city PRIMARY KEY (city_id, buildtime, time);

Make sure that there are no records where time is NULL, otherwise you won't be able to re-create the constraint.

Your syntax is incorrect, you should either specify a hash:

hash = {abc: true, def: true, ghi: true};

Or an array:

arr = ['abc','def','ghi'];

You can effectively remove an item from a hash by simply setting it to null:

hash['def'] = null;
hash.def = null;

Or removing it entirely:

delete hash.def;

To remove an item from an array you have to iterate through each item and find the one you want (there may be duplicates). You could use array searching and splicing methods:

arr.splice(arr.indexOf("def"), 1);

This finds the first index of "def" and then removes it from the array with splice. However I would recommend .filter() because it gives you more control:

arr.filter(function(item) { return item !== 'def'; });

This will create a new array with only elements that are not 'def'.

It is important to note that arr.filter() will return a new array, while arr.splice will modify the original array and return the removed elements. These can both be useful, depending on what you want to do with the items.

What is count1 set to? If it is not set, it looks like the empty string - and that would lead to an invalid expression. Which shell are you using?

In Bash 3.x on MacOS X 10.7.1:

$ count7=0
$ count7=$(($count7 + $count1))
-sh: 0 + : syntax error: operand expected (error token is " ")
$ count1=2
$ count7=$(($count7 + $count1))
$ echo $count7
2
$

You could also use ${count1:-0} to add 0 if $count1 is unset.

After :

sockfd = socket(AF_INET, SOCK_STREAM, 0);
if (sockfd < 0) 
    error("ERROR opening socket");

You can add (with standard C99 compound literal support) :

if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &(int){1}, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Or :

int enable = 1;
if (setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &enable, sizeof(int)) < 0)
    error("setsockopt(SO_REUSEADDR) failed");

Use a common table expression to add grand total row, top 100 is required for order by to work.

With Detail as 
(
    SELECT  top 100 propertyId, SUM(Amount) as TOTAL_COSTS
    FROM MyTable
    WHERE EndDate IS NULL
    GROUP BY propertyId
    ORDER BY TOTAL_COSTS desc
)

Select * from Detail
Union all
Select ' Total ', sum(TOTAL_COSTS) from Detail

You can also maintain a flag value based on listener,

 radioButton.setOnCheckedChangeListener(new OnCheckedChangeListener() {

            public void onCheckedChanged(CompoundButton arg0, boolean arg1) {

                //handle the boolean flag here. 
                  if(arg1==true)
                         //Do something

                else 
                    //do something else

            }
        });

Or simply isChecked() can also be used to check the state of your RadioButton.

Here is a link to a sample,

http://www.mkyong.com/android/android-radio-buttons-example/

And then based on the flag you can execute your function.

Array.prototype.remove = function(x) {
    var y=this.slice(x+1);
    var z=[];
    for(i=0;i<=x-1;i++) {
        z[z.length] = this[i];
    }

    for(i=0;i<y.length;i++){
        z[z.length]=y[i];
    }

    return z;
}

Also make sure that account is not locked out in user properties "Status" tab

Try this:

import java.util.Scanner;

    /* Logic: Consider first character in the string and start counting occurrence of        
              this character in the entire string. Now add this character to a empty
              string "temp" to keep track of the already counted characters.
              Next start counting from next character and start counting the character        
              only if it is not present in the "temp" string( which means only if it is
              not counted already)
public class Counting_Occurences {

    public static void main(String[] args) {


        Scanner input=new Scanner(System.in);
        System.out.println("Enter String");
        String str=input.nextLine();

        int count=0;
        String temp=""; // An empty string to keep track of counted
                                    // characters


        for(int i=0;i<str.length();i++)
        {

            char c=str.charAt(i);  // take one character (c) in string

            for(int j=i;j<str.length();j++)
            {

                char k=str.charAt(j);  
    // take one character (c) and compare with each character (k) in the string
            // also check that character (c) is not already counted.
            // if condition passes then increment the count.
                if(c==k && temp.indexOf(c)==-1)                                                                          
                {

                    count=count+1;

                }

            }

             if(temp.indexOf(c)==-1)  // if it is not already counted
             {


            temp=temp+c; // append the character to the temp indicating
                                         // that you have already counted it.

System.out.println("Character   " + c + "   occurs   " + count + "    times");
             }  
            // reset the counter for next iteration 
              count=0;

        }


    }


}

You can rename the directory using the file system. Then you can do git rm <old directory> and git add <new directory> (Help page). Then you can commit and push.

Git will detect that the contents are the same and that it's just a rename operation, and it'll appear as a rename entry in the history. You can check that this is the case before the commit using git status

=A1+TIME(1,0,0)

Although, maybe this should be posted on Super User.

A gcc/g++ specific way to suppress the unused parameter warning for a block of source code is to enclose it with the following pragma statements:

#pragma GCC diagnostic push
#pragma GCC diagnostic ignored "-Wunused-parameter"
<code with unused parameters here>
#pragma GCC diagnostic pop

// const path = 'info.value[0].item'
// const obj = { info: { value: [ { item: 'it works!' } ], randominfo: 3 }  }
// getValue(path, obj)

export const getValue = ( path , obj) => {
  const newPath = path.replace(/\]/g, "")
  const arrayPath = newPath.split(/[\[\.]+/) || newPath;

  const final = arrayPath.reduce( (obj, k) => obj ?  obj[k] : obj, obj)
  return final;
}

To send a message to a user you first need a User instance representing the user you want to send the message to.

Obtaining a User instance

• You can obtain a User instance from a message the user sent by doing message.autor
• You can obtain a User instance from a user id with client.fetchUser

Once you got a user instance you can send the message with .send

Examples

client.on('message', (msg) => {
 if (!msg.author.bot) msg.author.send('ok ' + msg.author.id);
});

client.fetchUser('487904509670337509', false).then((user) => {
 user.send('heloo');
});

You should be able to access the document in the IFRAME using the following code:

document.getElementById('myframe').contentWindow.document

However, you will not be able to do this if the page in the frame is loaded from a different domain (such as google.com). THis is because of the browser's Same Origin Policy.

The main difference is that Boolean is an object and boolean is an primitive.

• Object default value is null;
• boolean default value is false;

A great place to start learning about Subversion is http://svnbook.red-bean.com/.

As far as Visual Studio tools are concerned, I like AnkhSVN, but I haven't tried the VisualSVN plugin yet.

VisualSVN does rely on TortoiseSVN, but TortoiseSVN is also a nice complement to Ankh IMHO.

None of the above worked for me.

This happened to me after I added a new button to a toolstrip on a winform. When the button uses the default image of System.Drawing.Bitmap (in image property) this error arose for me. After I changed it to a trusted image (one added to my resource file with 'Unlock' option checked) this error resolved itself.

I use this extension method to accomplish something similar:

public static string GetFriendlyTypeName(this Type t)
{
    var typeName = t.Name.StripStartingWith("`");
    var genericArgs = t.GetGenericArguments();
    if (genericArgs.Length > 0)
    {
        typeName += "<";
        foreach (var genericArg in genericArgs)
        {
            typeName += genericArg.GetFriendlyTypeName() + ", ";
        }
        typeName = typeName.TrimEnd(',', ' ') + ">";
    }
    return typeName;
}

public static string StripStartingWith(this string s, string stripAfter)
{
    if (s == null)
    {
        return null;
    }
    var indexOf = s.IndexOf(stripAfter, StringComparison.Ordinal);
    if (indexOf > -1)
    {
        return s.Substring(0, indexOf);
    }
    return s;
}

You use it like this:

[TestMethod]
public void GetFriendlyTypeName_ShouldHandleReallyComplexTypes()
{
    typeof(Dictionary<string, Dictionary<string, object>>).GetFriendlyTypeName()
        .ShouldEqual("Dictionary<String, Dictionary<String, Object>>");
}

This isn't quite what you're looking for, but it's helpful in demonstrating the techniques involved.

I am using Ubuntu and my sessions are stored in /var/lib/php5.

After all of the steps listed here failed for me I got it working by running VS2015 as administrator.

For disabling a button add css class disabled to it . write

$("button").addClass('disabled')

Did you include "bootstrap-theme.css" files on your code?

In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).

It will re-declare your style code, and then it will be effected on your code.

So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.

When you override OnCreateView in your RouteSearchFragment class, do you have the

if(view != null) {
    return view; 
}

code segment?

If so, removing the return statement should solve your problem.

You can keep the code and return the view if you don't want to regenerate view data, and onDestroyView() method you remove this view from its parent like so:

    @Override
    public void onDestroyView() {
        super.onDestroyView();
        if (view != null) {
            ViewGroup parent = (ViewGroup) view.getParent();
            if (parent != null) {
                parent.removeAllViews();
            }
        }
    }

From strdup man:

The strdup() function shall return a pointer to a new string, which is a duplicate of the string pointed to by s1. The returned pointer can be passed to free(). A null pointer is returned if the new string cannot be created.

String strJson="{\"Employee\":
[{\"id\":\"101\",\"name\":\"Pushkar\",\"salary\":\"5000\"},
{\"id\":\"102\",\"name\":\"Rahul\",\"salary\":\"4000\"},
{\"id\":\"103\",\"name\":\"tanveer\",\"salary\":\"56678\"}]}";

This is an example of a JSON string with Employee as object, then multiple strings and values in an array as a reference to @cregox...

A bit complicated but can explain a lot in a single JSON string.
