Additional to all useful suggestions here, if you are using EF 6.1.3, get sure your project's .net version is 4.5 or more.

The pg_ctl status command suggested in other answers checks that the postmaster process exists and if so reports that it's running. That doesn't necessarily mean it is ready to accept connections or execute queries.

It is better to use another method like using psql to run a simple query and checking the exit code, e.g. psql -c 'SELECT 1', or use pg_isready to check the connection status.

I agree with Paul Tomblin. I usually use the keyset's iterator, and then base my condition off the value for that key:

Iterator<Integer> it = map.keySet().iterator();
while(it.hasNext()) {
    Integer key = it.next();
    Object val = map.get(key);
    if (val.shouldBeRemoved()) {
        it.remove();
    }
}

You should specify the region in your CLI script, rather than rely on default region specified using aws configure (as the current most popular answer asserts). Another answer alluded to that, but the syntax is wrong if you're using CLI via AWS Tools for Powershell.

This example forces region to us-west-2 (Northern California), PowerShell syntax:

aws s3 ls --region us-west-2

What it basically is

It's incorrect syntax that causes MySQL to think you're trying to do something with a column or parameter that has the incorrect type "DOUBLE".

Learn from my mistake

In my case I updated the varchar column in a table setting NULL where the value 0 stood. My update query was like this:

UPDATE myTable SET myValue = NULL WHERE myValue = 0;

Now, since the actual type of myValue is VARCHAR(255) this gives the warning:

+---------+------+-----------------------------------------------+
| Level   | Code | Message                                       |
+---------+------+-----------------------------------------------+
| Warning | 1292 | Truncated incorrect DOUBLE value: 'value xyz' |
+---------+------+-----------------------------------------------+

And now myTable is practically empty, because myValue is now NULL for EVERY ROW in the table! How did this happen?
^{*internal screaming*}

Over 30k rows now have missing data.
^{*internal screaming intensifies*}

Thank goodness for backups. I was able to recover all the data.
^{*internal screaming intensity lowers*}

The corrected query is as follows:

UPDATE myTable SET myValue = NULL WHERE myValue = '0';
                                                  ^^^
                                                  Quotation here!

I wish this was more than just a warning so it's less dangerous to forget those quotes.

In my case, while playing video, I needed to call a function everytime currentTime of video updates. So I used timeupdate event of video and I came to know that it was fired at least 4 times a second (depends on the browser you use, see this). So I changed it to call a function every second like this:

var currentIntTime = 0;

var someFunction = function() {
    currentIntTime++;
    // Do something here
} 
vidEl.on('timeupdate', function(){
    if(parseInt(vidEl.currentTime) > currentIntTime) {
        someFunction();
    }
});

This reduces calls to someFunc by at least 1/3 and it may help your browser to behave normally. It did for me !!!

The simplest choice I found to solve this problem was using the python lib called networkx.

It implements the Johnson's algorithm mentioned in the best answer of this question but it makes quite simple to execute.

In short you need the following:

import networkx as nx
import matplotlib.pyplot as plt

# Create Directed Graph
G=nx.DiGraph()

# Add a list of nodes:
G.add_nodes_from(["a","b","c","d","e"])

# Add a list of edges:
G.add_edges_from([("a","b"),("b","c"), ("c","a"), ("b","d"), ("d","e"), ("e","a")])

#Return a list of cycles described as a list o nodes
list(nx.simple_cycles(G))

Answer: [['a', 'b', 'd', 'e'], ['a', 'b', 'c']]

jakub.g's answer is correct, however an example using grunt seems a bit complex.

So my simpler answer:

- Sending a command line argument to an npm script

Syntax for sending command line arguments to an npm script:

npm run [command] [-- <args>]

Imagine we have an npm start task in our package.json to kick off webpack dev server:

"scripts": {
  "start": "webpack-dev-server --port 5000"
},

We run this from the command line with npm start

Now if we want to pass in a port to the npm script:

"scripts": {
  "start": "webpack-dev-server --port process.env.port || 8080"
},

running this and passing the port e.g. 5000 via command line would be as follows:

npm start --port:5000

- Using package.json config:

As mentioned by jakub.g, you can alternatively set params in the config of your package.json

"config": {
  "myPort": "5000"
}

"scripts": {
  "start": "webpack-dev-server --port process.env.npm_package_config_myPort || 8080"
},

npm start will use the port specified in your config, or alternatively you can override it

npm config set myPackage:myPort 3000

- Setting a param in your npm script

An example of reading a variable set in your npm script. In this example NODE_ENV

"scripts": {
  "start:prod": "NODE_ENV=prod node server.js",
  "start:dev": "NODE_ENV=dev node server.js"
},

read NODE_ENV in server.js either prod or dev

var env = process.env.NODE_ENV || 'prod'

if(env === 'dev'){
    var app = require("./serverDev.js");
} else {
    var app = require("./serverProd.js");
}

Set the value from code on showing the form, not in the design-timeProperties for the text box.

Private Sub UserForm_Activate()
    Me.txtDate.Value = Format(Date, "mm/dd/yy")
End Sub

I did Install-Package Microsoft.AspNet.WebApi.Core -version 5.2.3 but it still did not work. Then looked in my project bin folder and saw that it still had the old System.Web.Mvc file.

So I manually copied the newer file from the package to the bin folder. Then I was up and running again.

By using the constraint definition on table creation, you can specify one or multiple constraints that span multiple columns. The syntax, simplified from technet's documentation, is in the form of:

CONSTRAINT constraint_name UNIQUE [ CLUSTERED | NONCLUSTERED ] 
(
    column [ ASC | DESC ] [ ,...n ]
)

Therefore, the resuting table definition would be:

CREATE TABLE [dbo].[user](
    [userID] [int] IDENTITY(1,1) NOT NULL,
    [fcode] [int] NULL,
    [scode] [int] NULL,
    [dcode] [int] NULL,
    [name] [nvarchar](50) NULL,
    [address] [nvarchar](50) NULL,
    CONSTRAINT [PK_user_1] PRIMARY KEY CLUSTERED 
    (
        [userID] ASC
    ),
    CONSTRAINT [UQ_codes] UNIQUE NONCLUSTERED
    (
        [fcode], [scode], [dcode]
    )
) ON [PRIMARY]

I didn't touch the "save to a folder" option. I just copied the two files/directories you mentioned in your question to the new machine, then ran defaults read com.googlecode.iterm2.

See https://apple.stackexchange.com/a/111559

Here is my 2 cents:

double dX = x1 - x2;
double dY = y1 - y2;
double multi = dX * dX + dY * dY;
double rad = Math.Round(Math.Sqrt(multi), 3, MidpointRounding.AwayFromZero);

x1, y1 is the first coordinate and x2, y2 the second. The last line is the square root with it rounded to 3 decimal places.

SOLUTION: DELETE THAT LINE OF CODE [*IF YOU COPIED IT FROM ANOTHER SOURCE DOCUMENT] AND TYPE IT YOURSELF.

Error: stray '\240' in program is simply a character encoding error message.

From my experience, it is just a matter of character encoding. For example, if you copy a piece of code from a web page or you first write it in a text editor before copying and pasting in an IDE, it can come with the character encoding of the source document or editor.

Simple solution that actually renames the elements in-place, not creating a copy, and does a pretty good job of replacing the attributes.

public void RemoveAllNamespaces(ref XElement value)
{
  List<XAttribute> attributesToRemove = new List<XAttribute>();
  foreach (void e_loopVariable in value.DescendantsAndSelf) {
    e = e_loopVariable;
    if (e.Name.Namespace != XNamespace.None) {
      e.Name = e.Name.LocalName;
    }
    foreach (void a_loopVariable in e.Attributes) {
      a = a_loopVariable;
      if (a.IsNamespaceDeclaration) {
        //do not keep it at all
        attributesToRemove.Add(a);
      } else if (a.Name.Namespace != XNamespace.None) {
        e.SetAttributeValue(a.Name.LocalName, a.Value);
        attributesToRemove.Add(a);
      }
    }
  }
  foreach (void a_loopVariable in attributesToRemove) {
    a = a_loopVariable;
    a.Remove();
  }
}

Note: this does not always preserve original attribute order, but I'm sure you could change it to do that pretty easily if it's important to you.

Also note that this also could throw an exception, if you had an XElement attributes that are only unique with the namespace, like:

<root xmlns:ns1="a" xmlns:ns2="b">
    <elem ns1:dupAttrib="" ns2:dupAttrib="" />
</root>

which really seems like an inherent problem. But since the question indicated outputing a String, not an XElement, in this case you could have a solution that would output a valid String that was an invalid XElement.

I also liked jocull's answer using a custom XmlWriter, but when I tried it, it did not work for me. Although it all looks correct, I couldn't tell if the XmlNoNamespaceWriter class had any effect at all; it definitely was not removing the namespaces as I wanted it to.

Code check:

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

Passing [] as second argument to dict.fromkeys() gives a rather useless result – all values in the dictionary will be the same list object.

In Python 2.7 or above, you can use a dicitonary comprehension instead:

data = {k: [] for k in range(2)}

In earlier versions of Python, you can use

data = dict((k, []) for k in range(2))

Be aware that the Path is case sensitive. I tried setx PATH and it didn't work. In my case it was setx Path. Make sure your CMD run as Administrator.

setx Path "%PATH%;C:\Program Files\nodejs"

Now just restart your command prompt (or restart the PC) and the node command should be available.

The

Microsoft.AspNetCore.Cors

will allow you to do CORS with built-in features, but it does not handle OPTIONS request. The best workaround so far is creating a new Middleware as suggested in a previous post. Check the answer marked as correct in the following post:

Enable OPTIONS header for CORS on .NET Core Web API

Avoid overflow bug

unsigned i, number;
...
for (i=2; i*i<=number; i++) {  // Buggy
for (i=2; i*i<=number; i += 2) {  // Buggy
// or
for (i=5; i*i<=number; i+=6) { // Buggy

These forms are incorrect when number is a prime and i*i is near the max value of the type.

Problem exists with all integer types, signed, unsigned and wider.

Example:

Let UINT_MAX_SQRT as the floor of the square root of the maximum integer value. E.g. 65535 when unsigned is 32-bit.

With for (i=2; i*i<=number; i++), this 10-year old failure occurs because when UINT_MAX_SQRT*UINT_MAX_SQRT <= number and number is a prime, the next iteration results in a multiplication overflow. Had the type been a signed type, the overflow is UB. With unsigned types, this itself is not UB, yet logic has broken down. Interations continue until a truncated product exceeds number. An incorrect result may occur. With 32-bit unsigned, try 4,294,967,291? which is a prime.

If some_integer_type_MAX been a Mersenne Prime, i*i<=number is never true.

To avoid this bug, consider that number%i, number/i is efficient on many compilers as the calculations of the quotient and remainder are done together, thus incurring no extra cost to do both vs. just 1.

A simple full-range solution:

bool IsPrime(unsigned number) {
    for(unsigned i = 2; i <= number/i; i++){
        if(number % i == 0){
            return false;
        }
    }
    return number >= 2;
}

Try @Cacheable from jcabi-aspects. With a single annotation you make the entire method result cacheable in memory:

public class Resource {
  @Cacheable(lifetime = 5, unit = TimeUnit.SECONDS)
  public String load(URL url) {
    return url.openConnection().getContent();
  }
}

Also, read this article: http://www.yegor256.com/2014/08/03/cacheable-java-annotation.html

The above code will certainly help in converting HTML to PDF but will fail if the the HTML code has IMG tags with relative paths. iTextSharp library does not automatically convert relative paths to absolute ones.

I tried the above code and added code to take care of IMG tags too.

$name -replace ";*",""

You were close, but you used the syntax of a wildcard expresson rather than a regular expression, which is what the -replace operator expects.

Therefore (hash sequence shortened):

PS> 'test.txt ; 131 136 80 89 119 17 60 123 210 121 188' -replace '\s*;.*'
test.txt

Note:

• Omitting the substitution-text operand (the 2nd RHS operand) implicitly uses "" (the empty string), i.e. it effectively removes what the regex matched.

• .* is what represents a potentially empty run (*) of characters (.) in a regex - it is the regex equivalent of * by itself in a wildcard expression.

• Adding \s* before the ; in the regex also removes trailing whitespace (\s) after the filename.

• I've used '...' rather than "..." to enclose the regex, so as to prevent confusion between what PowerShell expands up front (see expandable strings in PowerShell and what the .NET regex engine sees.

You can make use of VALUES - available in Postgres:

INSERT INTO person (name)
    SELECT name FROM person
    UNION 
    VALUES ('Bob')
    EXCEPT
    SELECT name FROM person;

You should not expose this info. in public, specially api keys. It may lead to a privacy leak.

Before making the website public you should hide it. You can do it in 2 or more ways

1. Complex coding/hiding
2. Simply put firebase SDK codes at bottom of your website or app thus firebase automatically does all works. you don't need to put API keys anywhere

You can implement non-blocking locks using compareAndSwap (CAS) on atomic integers or longs. The "Tl2" Software Transactional Memory paper describes this:

We associate a special versioned write-lock with every transacted memory location. In its simplest form, the versioned write-lock is a single word spinlock that uses a CAS operation to acquire the lock and a store to release it. Since one only needs a single bit to indicate that the lock is taken, we use the rest of the lock word to hold a version number.

What it is describing is first read the atomic integer. Split this up into an ignored lock-bit and the version number. Attempt to CAS write it as the lock-bit cleared with the current version number to the lock-bit set and the next version number. Loop until you succeed and your are the thread which owns the lock. Unlock by setting the current version number with the lock-bit cleared. The paper describes using the version numbers in the locks to coordinate that threads have a consistent set of reads when they write.

This article describes that processors have hardware support for compare and swap operations making the very efficient. It also claims:

non-blocking CAS-based counters using atomic variables have better performance than lock-based counters in low to moderate contention

The simplest method (inline, assuming a and b are two given arrays):

byte[] c = (new String(a, cch) + new String(b, cch)).getBytes(cch);

This, of course, works with more than two summands and uses a concatenation charset, defined somewhere in your code:

static final java.nio.charset.Charset cch = java.nio.charset.StandardCharsets.ISO_8859_1;

Or, in more simple form, without this charset:

byte[] c = (new String(a, "l1") + new String(b, "l1")).getBytes("l1");

But you need to suppress UnsupportedEncodingException which is unlikely to be thrown.

The fastest method:

public static byte[] concat(byte[] a, byte[] b) {
    int lenA = a.length;
    int lenB = b.length;
    byte[] c = Arrays.copyOf(a, lenA + lenB);
    System.arraycopy(b, 0, c, lenA, lenB);
    return c;
}

I suspect you can adjust your approach a little and use something along the lines of the example here:

https://www.typescriptlang.org/docs/handbook/advanced-types.html#user-defined-type-guards

function isFish(pet: Fish | Bird): pet is Fish {
  return (pet as Fish).swim !== undefined;
}

My 2 cents.

This is a loaded question imho. A rule of thumb I use to is see how this function will be called. If the caller is something I have control over then , its ok to assume that it will be called with the right parameters and with proper initialization.

On the other hand if its some client I don't control then it is a good idea to do thorough error checking.

if you don't want recursion you could try:

x = [u'sam', [['Test', [['one', [], []]], [(u'file.txt', ['id', 1, 0])]], ['Test2', [], [(u'file2.txt', ['id', 1, 2])]]], []]
layer1=x
layer2=[]
while True:
    for i in layer1:
        if isinstance(i,list):
            for j in i:
                layer2.append(j)
        else:
            print i
    layer1[:]=layer2
    layer2=[]
    if len(layer1)==0:
        break

which gives:

sam
Test
Test2
(u'file.txt', ['id', 1, 0])
(u'file2.txt', ['id', 1, 2])
one

(note that it didn't look into the tuples for lists because the tuples aren't lists. You can add tuple to the "isinstance" method if you want to fix this)

tl;dr.

Matches all URL examples on this question and then some.

let re = /^(https?:\/\/)?((www\.)?(youtube(-nocookie)?|youtube.googleapis)\.com.*(v\/|v=|vi=|vi\/|e\/|embed\/|user\/.*\/u\/\d+\/)|youtu\.be\/)([_0-9a-z-]+)/i;
let id = "https://www.youtube.com/watch?v=l-gQLqv9f4o".match(re)[7];

ID will always be in match group 7.

Live examples of all the URLs I grabbed from the answers to this question: https://regexr.com/3u0d4

Full explanation:

As many answers/comments have brought up, there are many formats for youtube video URLs. Even multiple TLDs where they can appear to be "hosted".

You can look at the full list of variations I checked against by following the regexr link above.

Lets break down the RegExp.

^ Lock the string to the start of the string. (https?:\/\/)? Optional protocols http:// or https:// The ? makes the preceding item optional so the s and then the entire group (anything enclosed in a set of parenthesis) are optional.

Ok, this next part is the meat of it. Basically we have two options, the various versions of www.youtube.com/...[id] and the link shortened youtu.be/[id] version.

(                                                  // Start a group which will match everything after the protocol and up to just before the video id.
  (www\.)?                                         // Optional www.
  (youtube(-nocookie)?|youtube.googleapis)         // There are three domains where youtube videos can be accessed. This matches them.
  \.com                                            // The .com at the end of the domain. 
  .*                                               // Match anything 
  (v\/|v=|vi=|vi\/|e\/|embed\/|user\/.*\/u\/\d+\/) // These are all the things that can come right before the video id. The | character means OR so the first one in the "list" matches.
  |                                                // There is one more domain where you can get to youtube, it's the link shortening url which is just followed by the video id. This OR separates all the stuff in this group and the link shortening url.
  youtu\.be\/                                      // The link shortening domain
)                                                  // End of group

Finally we have the group to select the video ID. At least one character that is a number, letter, underscore, or dash.

([_0-9a-z-]+)

You can find out much more detail about each part of the regex by heading over the regexr link and seeing how each part of the expression matches with the text in the url.

I found this arrow(start, end) function on MATLAB Central which is perfect for this purpose of drawing vectors with true magnitude and direction.

The code is correct. The problem must lie somewhere else. Try the minimalistic example from the std::getline documentation.

main ()
{
    std::string name;

    std::cout << "Please, enter your full name: ";
    std::getline (std::cin,name);
    std::cout << "Hello, " << name << "!\n";

    return 0;
}

They are the inverse of each other. JSON.stringify() serializes a JS object into a JSON string, whereas JSON.parse() will deserialize a JSON string into a JS object.

JavaScript code using ng-controller:

$scope.checkkey = function (event) {
  alert(event.keyCode);  //this will show the ASCII value of the key pressed

}

In HTML:

<input type="text" ng-keypress="checkkey($event)" />

You can now place your checks and other conditions using the keyCode method.

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

Basically <key>ITSAppUsesNonExemptEncryption</key><false/> stands for a Boolean value equal to NO.

Update by @JosepH: This value means that the app uses no encryption, or only exempt encryption. If your app uses encryption and is not exempt, you must set this value to YES/true.

It seems debatable sometimes when an app is considered to use encryption.

Alternatively, if the method on Child is truly static (not a product of current props, state) you can define it on statics and then access it as you would a static class method. For example:

var Child = React.createClass({
  statics: {
    someMethod: function() {
      return 'bar';
    }
  },
  // ...
});

console.log(Child.someMethod()) // bar

Java 8 solution

We can use lambda expression or method reference introduced in Java 8. In case we have some String values stored in the Priority Queue (having capacity 5) we can provide inline comparator (based on length of String) :

Using lambda expression

PriorityQueue<String> pq=
                    new PriorityQueue<String>(5,(a,b) -> a.length() - b.length());

Using Method reference

PriorityQueue<String> pq=
                new PriorityQueue<String>(5, Comparator.comparing(String::length));

Then we can use any of them as:

public static void main(String[] args) {
        PriorityQueue<String> pq=
                new PriorityQueue<String>(5, (a,b) -> a.length() - b.length());
       // or pq = new PriorityQueue<String>(5, Comparator.comparing(String::length));
        pq.add("Apple");
        pq.add("PineApple");
        pq.add("Custard Apple");
        while (pq.size() != 0)
        {
            System.out.println(pq.remove());
        }
    }

This will print:

Apple
PineApple
Custard Apple

To reverse the order (to change it to max-priority queue) simply change the order in inline comparator or use reversed as:

PriorityQueue<String> pq = new PriorityQueue<String>(5, 
                             Comparator.comparing(String::length).reversed());

We can also use Collections.reverseOrder:

PriorityQueue<Integer> pqInt = new PriorityQueue<>(10, Collections.reverseOrder());
PriorityQueue<String> pq = new PriorityQueue<String>(5, 
                Collections.reverseOrder(Comparator.comparing(String::length))

So we can see that Collections.reverseOrder is overloaded to take comparator which can be useful for custom objects. The reversed actually uses Collections.reverseOrder:

default Comparator<T> reversed() {
    return Collections.reverseOrder(this);
}

offer() vs add()

As per the doc

The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues.

When using a capacity-restricted queue, offer() is generally preferable to add(), which can fail to insert an element only by throwing an exception. And PriorityQueue is an unbounded priority queue based on a priority heap.

FindControl does not search within nested controls recursively. It does only find controls that's NamigContainer is the Control on that you are calling FindControl.

Theres a reason that ASP.Net does not look into your nested controls recursively by default:

• Performance
• Avoiding errors
• Reusability

Consider you want to encapsulate your GridViews, Formviews, UserControls etc. inside of other UserControls for reusability reasons. If you would have implemented all logic in your page and accessed these controls with recursive loops, it'll very difficult to refactor that. If you have implemented your logic and access methods via the event-handlers(f.e. RowDataBound of GridView), it'll be much simpler and less error-prone.

extension String {

    var removingWhitespaceAndNewLines: String {
        return removing(.whitespacesAndNewlines)
    }

    func removing(_ forbiddenCharacters: CharacterSet) -> String {
        return String(unicodeScalars.filter({ !forbiddenCharacters.contains($0) }))
    }
}

In my case in the bin folder was a non reference dll called Unity.MVC3 , i tried to search any reference to this in visual studio without success, so my solution was so easy as delete that dll from the bin folder.

Others have already given good answers on how to generate code at runtime so I thought I would address your second paragraph. I have some experience with this and just want to share a lesson I learned from that experience.

At the very least, I could define an interface that they would be required to implement, then they would provide a code 'section' that implemented that interface.

You may have a problem if you use an interface as a base type. If you add a single new method to the interface in the future all existing client-supplied classes that implement the interface now become abstract, meaning you won't be able to compile or instantiate the client-supplied class at runtime.

I had this issue when it came time to add a new method after about 1 year of shipping the old interface and after distributing a large amount of "legacy" data that needed to be supported. I ended up making a new interface that inherited from the old one but this approach made it harder to load and instantiate the client-supplied classes because I had to check which interface was available.

One solution I thought of at the time was to instead use an actual class as a base type such as the one below. The class itself can be marked abstract but all methods should be empty virtual methods (not abstract methods). Clients can then override the methods they want and I can add new methods to the base class without invalidating existing client-supplied code.

public abstract class BaseClass
{
    public virtual void Foo1() { }
    public virtual bool Foo2() { return false; }
    ...
}

Regardless of whether this problem applies you should consider how to version the interface between your code base and the client-supplied code.

FindIndex Extension

static class ArrayExtensions
{
    public static int FindIndex<T>(this T[] array, Predicate<T> match)
    {
        return Array.FindIndex(array, match);
    }
}

Usage

int[] array = { 9,8,7,6,5 };

var index = array.FindIndex(i => i == 7);

Console.WriteLine(index); // Prints "2"

Here's a fiddle with it.

Bonus: IndexOf Extension

I wrote this first not reading the question properly...

static class ArrayExtensions
{
    public static int IndexOf<T>(this T[] array, T value)
    {
        return Array.IndexOf(array, value);
    }   
}

Usage

int[] array = { 9,8,7,6,5 };

var index = array.IndexOf(7);

Console.WriteLine(index); // Prints "2"

Here's a fiddle with it.

To round a double to the nearest integer, just use round().

var x = 3.7
x.round() // x = 4.0

If you don't want to modify the original value, then use rounded():

let x = 3.7
let y = x.rounded() // y = 4.0. x = 3.7

As one might expect (or might not), a number like 3.5 is rounded up and a number like -3.5 is rounded down. If you need different rounding behavior than that, you can use one of the rounding rules. For example:

var x = 3.7
x.round(.towardZero) // 3.0

If you need an actual Int then just cast it to one (but only if you are certain that the Double won't be greater than Int.max):

let myInt = Int(myDouble.rounded())

Notes

• This answer is completely rewritten. My old answer dealt with the C math functions like round, lround, floor, and ceil. However, now that Swift has this functionality built in, I can no longer recommend using those functions. Thanks to @dfri for pointing this out to me. Check out @dfri's excellent answer here. I also did something similar for rounding a CGFloat.

This will print 'hello' 3 times without storing i...

[print('hello') for i in range(3)]

You simply need to remove v-bind (:) from selected and required attributes. Like this :-

<template>_x000D_
    <select class="form-control" v-model="selected" required @change="changeLocation">_x000D_
        <option selected>Choose Province</option>_x000D_
        <option v-for="option in options" v-bind:value="option.id" >{{ option.name }}</option>_x000D_
    </select>_x000D_
</template>

You are not binding anything to the vue instance through these attributes thats why it is giving error.

Use nolock when you are okay with the "dirty" data. Which means nolock can also read data which is in the process of being modified and/or uncommitted data.

It's generally not a good idea to use it in high transaction environment and that is why it is not a default option on query.

If you came here searching OpenID Connect (OIDC): OAuth 2.0 != OIDC

I recognize that this is tagged for oauth 2.0 and NOT OIDC, however there is frequently a conflation between the 2 standards since both standards can use JWTs and the aud claim. And one (OIDC) is basically an extension of the other (OAUTH 2.0). (I stumbled across this question looking for OIDC myself.)

OAuth 2.0 Access Tokens##

For OAuth 2.0 Access tokens, existing answers pretty well cover it. Additionally here is one relevant section from OAuth 2.0 Framework (RFC 6749)

For public clients using implicit flows, this specification does not provide any method for the client to determine what client an access token was issued to.
...
Authenticating resource owners to clients is out of scope for this specification. Any specification that uses the authorization process as a form of delegated end-user authentication to the client (e.g., third-party sign-in service) MUST NOT use the implicit flow without additional security mechanisms that would enable the client to determine if the access token was issued for its use (e.g., audience- restricting the access token).

OIDC ID Tokens##

OIDC has ID Tokens in addition to Access tokens. The OIDC spec is explicit on the use of the aud claim in ID Tokens. (openid-connect-core-1.0)

aud
REQUIRED. Audience(s) that this ID Token is intended for. It MUST contain the OAuth 2.0 client_id of the Relying Party as an audience value. It MAY also contain identifiers for other audiences. In the general case, the aud value is an array of case sensitive strings. In the common special case when there is one audience, the aud value MAY be a single case sensitive string.

furthermore OIDC specifies the azp claim that is used in conjunction with aud when aud has more than one value.

azp
OPTIONAL. Authorized party - the party to which the ID Token was issued. If present, it MUST contain the OAuth 2.0 Client ID of this party. This Claim is only needed when the ID Token has a single audience value and that audience is different than the authorized party. It MAY be included even when the authorized party is the same as the sole audience. The azp value is a case sensitive string containing a StringOrURI value.

Here is a part of code I use to direct my server.js file to angular dist folder, which was created after npm build

// Create link to Angular build directory
var distDir = __dirname + "/dist/";
app.use(express.static(distDir));

I fixed it by changing "/dist/" to "./dist/"

Those errors :

"CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage

CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage"

means you haven't installed mingw32-base.

Go to http://sourceforge.net/projects/mingw/files/latest/download?source=files

and then make sure you select "mingw32-base"

Make sure you set up environment variables correctly in PATH section. "C:\MinGW\bin"

After that open CMake and Select Installation --> Delete Cache.

And click configure button again. I solved the problem this way, hope you solve the problem.

To actually cover your pattern, i.e, valid file names according to your rules, I think that you need a little more. Note this doesn't match legal file names from a system perspective. That would be system dependent and more liberal in what it accepts. This is intended to match your acceptable patterns.

^([a-zA-Z0-9]+[_-])*[a-zA-Z0-9]+\.[a-zA-Z0-9]+$

Explanation:

• ^ Match the start of a string. This (plus the end match) forces the string to conform to the exact expression, not merely contain a substring matching the expression.
• ([a-zA-Z0-9]+[_-])* Zero or more occurrences of one or more letters or numbers followed by an underscore or dash. This causes all names that contain a dash or underscore to have letters or numbers between them.
• [a-zA-Z0-9]+ One or more letters or numbers. This covers all names that do not contain an underscore or a dash.
• \. A literal period (dot). Forces the file name to have an extension and, by exclusion from the rest of the pattern, only allow the period to be used between the name and the extension. If you want more than one extension that could be handled as well using the same technique as for the dash/underscore, just at the end.
• [a-zA-Z0-9]+ One or more letters or numbers. The extension must be at least one character long and must contain only letters and numbers. This is typical, but if you wanted allow underscores, that could be addressed as well. You could also supply a length range {2,3} instead of the one or more + matcher, if that were more appropriate.
• $ Match the end of the string. See the starting character.

It is a 32bit declaration. If you type at the top of an assembly file the statement [bits 32], then you don't need to type DWORD PTR. So for example:

[bits 32]
.
.
and  [ebp-4], 0

You could also use the iframe method, although this is not cross browser compatible (eg. not working in chromium or android and probably others -> instead prompts to download). It works with dataURL's and normal URLS, not sure if the other examples work with dataURLS (please let me know if the other examples work with dataURLS?)

 <iframe class="page-icon preview-pane" frameborder="0" height="352" width="396" src="data:application/pdf;base64, ..DATAURLHERE!... "></iframe>

var str ="fsdsd'4565sd"; str.replace(/'/g,"'")

This worked for me. Kindly try this

I'm using GDB7.1.1, as --help shows:

gdb [options] --args executable-file [inferior-arguments ...]

IMHO, the order is a bit unintuitive at first.

If you want to set Min 1 count and no Max length,

^.{1,}$

$('#dropdownid').empty();

That will remove all <option> elements underneath the dropdown element.

If you want to unselect selected items, go with the code from Russ.

Say you have array named list. The Splice() function can be used for both adding and removing item in that array in specific index i.e that can be in the beginning or in the end or at any index. On the contrary there are another function name shift() and pop() which is capable of removing only the first and last item in the array.

This is the Shift Function which is only capable of removing the first element of the array

var item = [ 1,1,2,3,5,8,13,21,34 ]; // say you have this number series 
item.shift(); // [ 1,2,3,5,8,13,21,34 ];

The Pop Function removes item from an array at its last index

item.pop(); // [ 1,2,3,5,8,13,21 ];

Now comes the splice function by which you can remove item at any index

item.slice(0,1); // [ 2,3,5,8,13,21 ] removes the first object
item.slice(item.length-1,1); // [ 2,3,5,8,13 ] removes the last object 

The slice function accepts two parameters (Index to start with, number of steps to go);

I have a solution to a problem that may also apply to you. My database was in a state where a DROP TABLE failed because it couldn't find the table... but a CREATE TABLE also failed because MySQL thought the table existed. (This state could easily mess with your IF NOT EXISTS clause).

I eventually found this solution:

sudo mysqladmin flush-tables

For me, without the sudo, I got the following error:

mysqladmin: refresh failed; error: 'Access denied; you need the RELOAD privilege for this operation'

(Running on OS X 10.6)

//As an HTTP redirect (back button will not work )
window.location.replace("http://www.google.com");

//like if you click on a link (it will be saved in the session history, 
//so the back button will work as expected)
window.location.href = "http://www.google.com";

Make sure that your WebAPI service is expecting a strongly typed object with a structure that matches the JSON that you are passing. And make sure that you stringify the JSON that you are POSTing.

Here is my JavaScript (using AngluarJS):

$scope.updateUserActivity = function (_objuserActivity) {
        $http
        ({
            method: 'post',
            url: 'your url here',
            headers: { 'Content-Type': 'application/json'},
            data: JSON.stringify(_objuserActivity)
        })
        .then(function (response)
        {
            alert("success");
        })
        .catch(function (response)
        {
            alert("failure");
        })
        .finally(function ()
        {
        });

And here is my WebAPI Controller:

[HttpPost]
[AcceptVerbs("POST")]
public string POSTMe([FromBody]Models.UserActivity _activity)
{
    return "hello";
}

In Windows, you can do it in this way:

import ctypes
PROCESS_QUERY_INFROMATION = 0x1000
def checkPid(pid):
    processHandle = ctypes.windll.kernel32.OpenProcess(PROCESS_QUERY_INFROMATION, 0,pid)
    if processHandle == 0:
        return False
    else:
        ctypes.windll.kernel32.CloseHandle(processHandle)
    return True

First of all, in this code you try to get a handle for process with pid given. If the handle is valid, then close the handle for process and return True; otherwise, you return False. Documentation for OpenProcess: https://msdn.microsoft.com/en-us/library/windows/desktop/ms684320%28v=vs.85%29.aspx

You can use RVM(Ruby version manager) which helps in managing all versions of ruby on your machine , which is very helpful for you development (when migrating to unstable release to stable release )

or for Linux (ubuntu) go for sudo apt-get install ruby1.8-dev

then sudo gem install rails to verify it do rails -v it will show version on rails

after that you can install bundles (required gems for development)

In Ruby and Perl 6 this has been called "splat", and I think most people from those communities will figure out what you mean if you call it that.

The Python tutorial uses the phrase "unpacking argument lists", which is long and descriptive.

It is also referred to as iterable unpacking, or in the case of **, dictionary unpacking.

See the documentation on setting up a pipeline using subprocess: http://docs.python.org/2/library/subprocess.html#replacing-shell-pipeline

I haven't tested the following code example but it should be roughly what you want:

query = "process_name"
ps_process = Popen(["ps", "-A"], stdout=PIPE)
grep_process = Popen(["grep", query], stdin=ps_process.stdout, stdout=PIPE)
ps_process.stdout.close()  # Allow ps_process to receive a SIGPIPE if grep_process exits.
output = grep_process.communicate()[0]

In order to prove that a problem L is NP-complete, we need to do the following steps:

1. Prove your problem L belongs to NP (that is that given a solution you can verify it in polynomial time)
2. Select a known NP-complete problem L'
3. Describe an algorithm f that transforms L' into L
4. Prove that your algorithm is correct (formally: x ? L' if and only if f(x) ? L )
5. Prove that algo f runs in polynomial time

Set the default value for the active argument in the route.

There is one thing to remember, when you are searching the object in array on the basis of more than one condition then use $elemMatch

Person.update(
   {
     _id: 5,
     grades: { $elemMatch: { grade: { $lte: 90 }, mean: { $gt: 80 } } }
   },
   { $set: { "grades.$.std" : 6 } }
)

here is the docs

Use the pandas.DataFrame.rename funtion. Check this link for description.

data.rename(columns = {'gdp': 'log(gdp)'}, inplace = True)

If you intend to rename multiple columns then

data.rename(columns = {'gdp': 'log(gdp)', 'cap': 'log(cap)', ..}, inplace = True)

I've seen:

hasattr(s, 'endswith') 

$array = array("Jonathan","Sampson");

foreach($array as $value) {
  print $value;
}

or

$length = count($array);
for ($i = 0; $i < $length; $i++) {
  print $array[$i];
}

The No input file specified is a message you are presented with because of the implementation of PHP on your server, which in this case indicates a CGI implementation (can be verified with phpinfo()).

Now, to properly explain this, you need to have some basic understanding on how your system works with URL's. Based on your .htaccess file, it seems that your CMS expects the URL to passed along as a PATH_INFO variable. CGI and FastCGI implementations do not have PATH_INFO available, so when trying to pass the URI along, PHP fails with that message.

We need to find an alternative.

One option is to try and fix this. Looking into the documentation for core php.ini directives you can see that you can change the workings for your implementation. Although, GoDaddy probably won't allow you to change PHP settings on a shared enviroment.

We need to find an alternative to modifying PHP settings
Looking into system/uri.php on line 40, you will see that the CMS attempts two types of URI detection - the first being PATH_INFO, which we just learned won't work - the other being the REQUEST_URI.

This should basically, be enough - but the parsing of the URI passed, will cause you more trouble, as the URI, which you could pass to REQUEST_URI variable, forces parse_url() to only return the URL path - which basically puts you back to zero.

Now, there's actually only one possibilty left - and that's changing the core of the CMS. The URI detection part is insufficient.

Add QUERY_STRING to the array on line 40 as the first element in system/uri.php and change your .htaccess to look like this:

RewriteEngine On 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d 

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

This will pass the URI you request to index.php as QUERY_STRING and have the URI detection to find it.

This, on the other hand, makes it impossible to update the CMS without changing core files till this have been fixed. That sucks...

Need a better option?
Find a better CMS.

Depends a lot on your definition of what a "character" is. If "rune equals a character " is OK for your task (generally it isn't) then the answer by VonC is perfect for you. Otherwise, it should be probably noted, that there are few situations where the number of runes in a Unicode string is an interesting value. And even in those situations it's better, if possible, to infer the count while "traversing" the string as the runes are processed to avoid doubling the UTF-8 decode effort.

You can use Eclipse Collections factories:

Iterable<String> iterable = Arrays.asList("1", "2", "3");

MutableList<String> list = Lists.mutable.withAll(iterable);
MutableSet<String> set = Sets.mutable.withAll(iterable);
MutableSortedSet<String> sortedSet = SortedSets.mutable.withAll(iterable);
MutableBag<String> bag = Bags.mutable.withAll(iterable);
MutableSortedBag<String> sortedBag = SortedBags.mutable.withAll(iterable);

You can also convert the Iterable to a LazyIterable and use the converter methods or any of the other available APIs available.

Iterable<String> iterable = Arrays.asList("1", "2", "3");
LazyIterable<String> lazy = LazyIterate.adapt(iterable);

MutableList<String> list = lazy.toList();
MutableSet<String> set = lazy.toSet();
MutableSortedSet<String> sortedSet = lazy.toSortedSet();
MutableBag<String> bag = lazy.toBag();
MutableSortedBag<String> sortedBag = lazy.toSortedBag();

All of the above Mutable types extend java.util.Collection.

        return this._http.get<SomeClassOrInterface>(this.url)
            .pipe(
                tap(data => console.log('server data:', data)), 
                catchError(this.handleError('getData'))
            );
    }

Old service, which uses the deprecated HttpModule:

import {Injectable}              from 'angular2/core';
import {Http, Response, Request} from 'angular2/http';
import {Observable}              from 'rxjs/Observable';
import 'rxjs/add/observable/throw';
//import 'rxjs/Rx';  // use this line if you want to be lazy, otherwise:
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/do';  // debug
import 'rxjs/add/operator/catch';

@Injectable()
export class MyService {
    constructor(private _http:Http) {}
    private _serverError(err: any) {
        console.log('sever error:', err);  // debug
        if(err instanceof Response) {
          return Observable.throw(err.json().error || 'backend server error');
          // if you're using lite-server, use the following line
          // instead of the line above:
          //return Observable.throw(err.text() || 'backend server error');
        }
        return Observable.throw(err || 'backend server error');
    }
    private _request = new Request({
        method: "GET",
        // change url to "./data/data.junk" to generate an error
        url: "./data/data.json"
    });
    // public API
    public getData() {
        return this._http.request(this._request)
          // modify file data.json to contain invalid JSON to have .json() raise an error
          .map(res => res.json())  // could raise an error if invalid JSON
          .do(data => console.log('server data:', data))  // debug
          .catch(this._serverError);
    }
}

I use .do() (now .tap()) for debugging.

When there is a server error, the body of the Response object I get from the server I'm using (lite-server) contains just text, hence the reason I use err.text() above rather than err.json().error. You may need to adjust that line for your server.

If res.json() raises an error because it could not parse the JSON data, _serverError will not get a Response object, hence the reason for the instanceof check.

In this plunker, change url to ./data/data.junk to generate an error.

Users of either service should have code that can handle the error:

@Component({
    selector: 'my-app',
    template: '<div>{{data}}</div> 
       <div>{{errorMsg}}</div>`
})
export class AppComponent {
    errorMsg: string;
    constructor(private _myService: MyService ) {}
    ngOnInit() {
        this._myService.getData()
            .subscribe(
                data => this.data = data,
                err  => this.errorMsg = <any>err
            );
    }
}

You need to alias the subquery.

SELECT name FROM (SELECT name FROM agentinformation) a  

or to be more explicit

SELECT a.name FROM (SELECT name FROM agentinformation) a  

How to POST mixed data: File, String[], String in one request.

You can use only what you need.

private String doPOST(File file, String[] array, String name) {
    RestTemplate restTemplate = new RestTemplate(true);

    //add file
    LinkedMultiValueMap<String, Object> params = new LinkedMultiValueMap<>();
    params.add("file", new FileSystemResource(file));

    //add array
    UriComponentsBuilder builder = UriComponentsBuilder.fromHttpUrl("https://my_url");
    for (String item : array) {
        builder.queryParam("array", item);
    }

    //add some String
    builder.queryParam("name", name);

    //another staff
    String result = "";
    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.MULTIPART_FORM_DATA);

    HttpEntity<LinkedMultiValueMap<String, Object>> requestEntity =
            new HttpEntity<>(params, headers);

    ResponseEntity<String> responseEntity = restTemplate.exchange(
            builder.build().encode().toUri(),
            HttpMethod.POST,
            requestEntity,
            String.class);

    HttpStatus statusCode = responseEntity.getStatusCode();
    if (statusCode == HttpStatus.ACCEPTED) {
        result = responseEntity.getBody();
    }
    return result;
}

The POST request will have File in its Body and next structure:

POST https://my_url?array=your_value1&array=your_value2&name=bob 

If you want an efficient way with milliseconds:

var daysOfYear = [];
for (var d = begin; d <= end; d = d + 86400000) {
    daysOfYear.push(new Date(d));
}

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

.row {
    margin-right: 15px;

You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build --build-arg arg=2.3 ..

//R stands for ROW and C stands for COLUMN:

//i stands for ROW and j stands for COLUMN:

#include<stdio.h>

int main(){

    int M[100][100];

    int R,C,i,j;

    printf("Please enter how many rows you want:\n");

    scanf("%d",& R);

    printf("Please enter how column you want:\n");

    scanf("%d",& C);

    printf("Please enter your matrix:\n");

    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            scanf("%d", &M[i][j]);

        }

        printf("\n");

    }
    for(i = 0; i < R; i++){

        for(j = 0; j < C; j++){

            printf("%d\t", M[i][j]);

        }
        printf("\n");

   }

   getch();

   return 0;
}

To add a new file in SVN

svn add file_name
svn commit -m "text about changes..."

To add a new file in a directory in SVN

svn add directory_name/file_name
svn commit -m "text about changes"

To add all new files in a directory with some targets (files) are already versioned (added):

svn add directory_name/*
svn commit -m "text about changes"

Try something like:

$post_data="dispnumber=567567567&extension=6";
$url="http://xxxxxxxx.xxx/xx/xx";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/x-www-form-urlencoded'));   
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
$result = curl_exec($ch);

echo $result;

From what I've found online, this is a bug introduced in JDK 1.7.0_45. It appears to also be present in JDK 1.7.0_60. A bug report on Oracle's website states that, while there was a fix, it was removed before the JDK was released. I do not know why the fix was removed, but it confirms what we've already suspected -- the JDK is still broken.

The bug report claims that the error is benign and should not cause any run-time problems, though one of the comments disagrees with that. In my own experience, I have been able to work without any problems using JDK 1.7.0_60 despite seeing the message.

If this issue is causing serious problems, here are a few things I would suggest:

• Revert back to JDK 1.7.0_25 until a fix is added to the JDK.

• Keep an eye on the bug report so that you are aware of any work being done on this issue. Maybe even add your own comment so Oracle is aware of the severity of the issue.

• Try the JDK early releases as they come out. One of them might fix your problem.

Instructions for installing the JDK on Mac OS X are available at JDK 7 Installation for Mac OS X. It also contains instructions for removing the JDK.

You can convert JSON Date to normal date format in JavaScript.

var date = new Date(parseInt(jsonDate.substr(6)));

File Path Seems to be an issue here please make sure that file exists in the correct directory or give the absolute path to make sure that you are pointing to a correct file. Please log the file.getAbsolutePath() to verify that file is correct.

Use offset() function of jQuery. Here it would be:

$container.offset({
        'left': 100,
        'top': mouse.y - ( event_state.mouse_y - event_state.container_top ) 
    });

The Most Elegant Solutions...

app.service('svc', function(){ this.attr = []; return this; });
app.controller('ctrl', function($scope, svc){
    $scope.attr = svc.attr || [];
    $scope.$watch('attr', function(neo, old){ /* if necessary */ });
});
app.run(function($rootScope, svc){
    $rootScope.svc = svc;
    $rootScope.$watch('svc', function(neo, old){ /* change the world */ });
});

Also, I write EDAs (Event-Driven Architectures) so I tend to do something like the following [oversimplified version]:

var Service = function Service($rootScope) {
    var $scope = $rootScope.$new(this);
    $scope.that = [];
    $scope.$watch('that', thatObserver, true);
    function thatObserver(what) {
        $scope.$broadcast('that:changed', what);
    }
};

Then, I put a listener in my controller on the desired channel and just keep my local scope up to date this way.

In conclusion, there's not much of a "Best Practice" -- rather, its mostly preference -- as long as you're keeping things SOLID and employing weak coupling. The reason I would advocate the latter code is because EDAs have the lowest coupling feasible by nature. And if you aren't too concerned about this fact, let us avoid working on the same project together.

Hope this helps...

As Simon mentioned, this is not possible in the new Facebook API. Pure technically speaking you can do it via browser automation.

• this is against Facebook policy, so depending on the country where you live, this may not be legal
• you'll have to use your credentials / ask user for credentials and possibly store them (storing passwords even symmetrically encrypted is not a good idea)
• when Facebook changes their API, you'll have to update the browser automation code as well (if you can't force updates of your application, you should put browser automation piece out as a webservice)
• this is bypassing the OAuth concept
• on the other hand, my feeling is that I'm owning my data including the list of my friends and Facebook shouldn't restrict me from accessing those via the API

Sample implementation using WatiN:

class FacebookUser
{
  public string Name { get; set; }
  public long Id { get; set; }
}

public IList<FacebookUser> GetFacebookFriends(string email, string password, int? maxTimeoutInMilliseconds)
{
  var users = new List<FacebookUser>();
  Settings.Instance.MakeNewIeInstanceVisible = false;
  using (var browser = new IE("https://www.facebook.com"))
  {
    try
    {
      browser.TextField(Find.ByName("email")).Value = email;
      browser.TextField(Find.ByName("pass")).Value = password;
      browser.Form(Find.ById("login_form")).Submit();
      browser.WaitForComplete();
    }
    catch (ElementNotFoundException)
    {
      // We're already logged in
    }
    browser.GoTo("https://www.facebook.com/friends");
    var watch = new Stopwatch();
    watch.Start();

    Link previousLastLink = null;
    while (maxTimeoutInMilliseconds.HasValue && watch.Elapsed.TotalMilliseconds < maxTimeoutInMilliseconds.Value)
    {
      var lastLink = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
                       && l.GetAttributeValue("data-hovercard").Contains("user.php")
                       && l.Text != null
                     ).LastOrDefault();

      if (lastLink == null || previousLastLink == lastLink)
      {
        break;
      }

      var ieElement = lastLink.NativeElement as IEElement;
      if (ieElement != null)
      {
        var htmlElement = ieElement.AsHtmlElement;
        htmlElement.scrollIntoView();
        browser.WaitForComplete();
      }

      previousLastLink = lastLink;
    }

    var links = browser.Links.Where(l => l.GetAttributeValue("data-hovercard") != null
      && l.GetAttributeValue("data-hovercard").Contains("user.php")
      && l.Text != null
    ).ToList();

    var idRegex = new Regex("id=(?<id>([0-9]+))");
    foreach (var link in links)
    {
      string hovercard = link.GetAttributeValue("data-hovercard");
      var match = idRegex.Match(hovercard);
      long id = 0;
      if (match.Success)
      {
        id = long.Parse(match.Groups["id"].Value);
      }
      users.Add(new FacebookUser
      {
        Name = link.Text,
        Id = id
      });
    }
  }
  return users;
}

Prototype with implementation of this approach (using C#/WatiN) see https://github.com/svejdo1/ShadowApi. It is also allowing dynamic update of Facebook connector that is retrieving a list of your contacts.

There's no reliable way to do this for all platforms and architectures using a simple script. If you want to learn how to do it reliably, start at the blog post Updated sample .NET Framework detection code that does more in-depth checking.

Yep, Use a better option source filter. If you're searching with JSON it'll look something like this:

{
    "_source": ["user", "message", ...],
    "query": ...,
    "size": ...
}

In ES 2.4 and earlier, you could also use the fields option to the search API:

{
    "fields": ["user", "message", ...],
    "query": ...,
    "size": ...
}

This is deprecated in ES 5+. And source filters are more powerful anyway!

First I recommend you as @ChrisHuang-Leaver suggested to define a new file with all the choices you need it there, like choices.py:

STATUS_CHOICES = (
    (1, _("Not relevant")),
    (2, _("Review")),
    (3, _("Maybe relevant")),
    (4, _("Relevant")),
    (5, _("Leading candidate"))
)
RELEVANCE_CHOICES = (
    (1, _("Unread")),
    (2, _("Read"))
)

Now you need to import them on the models, so the code is easy to understand like this(models.py):

from myApp.choices import * 

class Profile(models.Model):
    user = models.OneToOneField(User)    
    status = models.IntegerField(choices=STATUS_CHOICES, default=1)   
    relevance = models.IntegerField(choices=RELEVANCE_CHOICES, default=1)

And you have to import the choices in the forms.py too:

forms.py:

from myApp.choices import * 

class CViewerForm(forms.Form):

    status = forms.ChoiceField(choices = STATUS_CHOICES, label="", initial='', widget=forms.Select(), required=True)
    relevance = forms.ChoiceField(choices = RELEVANCE_CHOICES, required=True)

Anyway you have an issue with your template, because you're not using any {{form.field}}, you generate a table but there is no inputs only hidden_fields.

When the user is staff you should generate as many input fields as users you can manage. I think django form is not the best solution for your situation.

I think it will be better for you to use html form, so you can generate as many inputs using the boucle: {% for user in users_list %} and you generate input with an ID related to the user, and you can manage all of them in the view.

I implemented it in the following way. I wanted a generic MakeRequest method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string> object to house the content to be submitted, and then set the HttpRequestMessage Content property with it:

Generic method to call the API:

    private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
    {
        using (var client = new HttpClient())
        {
            HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");

            if (postParams != null)
                requestMessage.Content = new FormUrlEncodedContent(postParams);   // This is where your content gets added to the request body


            HttpResponseMessage response = client.SendAsync(requestMessage).Result;

            string apiResponse = response.Content.ReadAsStringAsync().Result;
            try
            {
                // Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
                if (apiResponse != "")
                    return JsonConvert.DeserializeObject<T>(apiResponse);
                else
                    throw new Exception();
            }
            catch (Exception ex)
            {
                throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
            }
        }
    }

Call the method:

    public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
    { 
        // Here you create your parameters to be added to the request content
        var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
        // make a POST request to the "cards" endpoint and pass in the parameters
        return MakeRequest<CardInformation>("POST", "cards", postParams);
    }

I found the answer here: Is it possible to pass query parameters via Django's {% url %} template tag?

Simply add them to the end:

<a href="{% url myview %}?office=foobar">
For Django 1.5+

<a href="{% url 'myview' %}?office=foobar">

[there is nothing else to improve but I'm getting a stupid error when I fix the code ticks]

I've refactored @Academy of Programmer's answer to shorter code and altered it so that it only hits https:// URLs:

    public static string GetExternalIPAddress()
    {
        string result = string.Empty;

        string[] checkIPUrl =
        {
            "https://ipinfo.io/ip",
            "https://checkip.amazonaws.com/",
            "https://api.ipify.org",
            "https://icanhazip.com",
            "https://wtfismyip.com/text"
        };

        using (var client = new WebClient())
        {
            client.Headers["User-Agent"] = "Mozilla/4.0 (Compatible; Windows NT 5.1; MSIE 6.0) " +
                "(compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";

            foreach (var url in checkIPUrl)
            {
                try
                {
                    result = client.DownloadString(url);
                }
                catch
                {
                }

                if (!string.IsNullOrEmpty(result))
                    break;
            }
        }

        return result.Replace("\n", "").Trim();
    }
}

stmt.setDate(1, new java.sql.Date(cal.getTime().getTime()));

You may also have to use it in onPause or onDestroy of Activity Life Cycle:

//you may call the cancel() method but if it is not handled in doInBackground() method
if (loginTask != null && loginTask.getStatus() != AsyncTask.Status.FINISHED)
    loginTask.cancel(true);

where loginTask is object of your AsyncTask

Thank you.

You likely want File.toPath().

Well, for starters, you might not wanna overuse echo, because (as is the problem in your case) you can very easily make mistakes on quotation marks.

This would fix your problem:

echo "<a href=\"http://www.whatever.com/$param\">Click Here</a>";

but you should really do this

<?php
  $param = "test";
?>
<a href="http://www.whatever.com/<?php echo $param; ?>">Click Here</a>

In jquery, u can delcare variable two styles.

One is,

$.name = 'anirudha';
alert($.name);

Second is,

var hText = $("#head1").text();

Second is used when you read data from textbox, label, etc.

You can easily do that with

git log master..branch-X

That will show you commits that branch-X has but master doesn't.

You can use CountIf. Put the following code in B1 and drag down the whole column

=COUNTIF(A:A,A1)

It will look like this:

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

use res.json, ajax, and promises, with a nice twist of localStorage to use it anywhere, added with tokens for that rare arcade love. PS, you could use cookies, but cookies can bite on https.

webpage.js

function (idToken) {
    $.ajax({
        url: '/main',
        headers: {
            Authorization: 'Bearer ' + idToken
        },
        processData: false,
    }).done(function (data) {
        localStorage.setItem('name', data.name);
        //or whatever you want done.
    }).fail(function (jqXHR, textStatus) {
        var msg = 'Unable to fetch protected resource';
        msg += '<br>' + jqXHR.status + ' ' + jqXHR.responseText;
        if (jqXHR.status === 401) {
            msg += '<br>Your token may be expired'
        }
        displayError(msg);
    });

server.js, using express()

app.get('/main',
passport.authenticate('oauth2-jwt-bearer', { session: false }),
function (req, res) {
    getUserInfo(req) //get your information to use it.
        .then(function (userinfo) {  //return your promise
            res.json({ "name": userinfo.Name});
            //you can declare/return more vars in this res.json.
            //res.cookie('name', name); //https trouble
        })
    .error(function (e) {console.log("Error handler " + e)})
    .catch(function (e) {console.log("Catch handler " + e)});
});

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

You could use...

<option <?= ($temp == $value) ? "SELECTED" : "" ?> >$value</opton>

Edit: I thought I was looking at PHP questions... Sorry.

The -I directive does the job:

gcc -Icore -Ianimator -Iimages -Ianother_dir -Iyet_another_dir my_file.c 

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

See MSDN Cast and Convert for more information.

You can't do this: {this.state.arrayFromJson} As your error suggests what you are trying to do is not valid. You are trying to render the whole array as a React child. This is not valid. You should iterate through the array and render each element. I use .map to do that.

I am pasting a link from where you can learn how to render elements from an array with React.

Formatting code in Visual Studio.

I have tried to format in Windows 8.

Just follow the screenshots below.

1. Click on View on the top menu bar, and then click on Command Palette.

   

2. Then a textbox would appear where we need type Format

   Shift + Alt + F

   

WordPress overrides PHP's memory limit to 256M, with the assumption that whatever it was set to before is going to be too low to render the dashboard. You can override this by defining WP_MAX_MEMORY_LIMIT in wp-config.php:

define( 'WP_MAX_MEMORY_LIMIT' , '512M' );

I agree with DanFromGermany, 256M is really a lot of memory for rendering a dashboard page. Changing the memory limit is really putting a bandage on the problem.

After installation of Oracle Client 11.02.04, reboot the server and make sure USERS(Local Computer) is added with Full Control on Root folder for eg WWW

Tested, it worked.

You can call [aDictionary description], or anywhere you would need a format string, just use %@ to stand in for the dictionary:

[NSString stringWithFormat:@"my dictionary is %@", aDictionary];

or

NSLog(@"My dictionary is %@", aDictionary);

In case anyone wants to have a responsive flexbox with percentages (%) it is much easier for media queries.

flex-basis: 25%;

This will be a lot smoother when testing.

    flex-basis: 25%;
}

@media screen (max-width: $screen-md) {
    flex-basis: 33.33%;
}

The below code works for all the screens :

.jumbotron {
   background: url('backgroundimage.jpg') no-repeat center center fixed;
   -webkit-background-size: cover;
   -moz-background-size: cover;
   background-size: cover;
   -o-background-size: cover;
}

The cover property will resize the background image to cover the entire container, even if it has to stretch the image or cut a little bit off one of the edges.

One needs to understand what a JOIN or a series of JOINs does to a set of data. With strae's post, a pe_id of 1 joined with corresponding order and items on pe_id = 1 will give you the following data to "select" from:

[ table people portion ] [ table orders portion ] [ table items portion ]

| people.pe_id | people.pe_name | orders.ord_id | orders.pe_id | orders.ord_title | item.item_id | item.ord_id | item.pe_id | item.title |

| 1 | Foo | 1 | 1 | First order | 1 | 1 | 1 | Apple |
| 1 | Foo | 1 | 1 | First order | 2 | 1 | 1 | Pear |

The joins essentially come up with a cartesian product of all the tables. You basically have that data set to select from and that's why you need a distinct count on orders.ord_id and items.item_id. Otherwise both counts will result in 2 - because you effectively have 2 rows to select from.

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

After several operations, when the page should finally go to <a href"..."> link you can do the following:

jQuery("a").click(function(e){
    var self = jQuery(this);
    var href = self.attr('href');
    e.preventDefault();
    // needed operations

    window.location = href;
});

Override service method like this:

protected void service(HttpServletRequest request, HttpServletResponse   response) throws ServletException, IOException {
        doPost(request, response);
}

And Voila!

The best approach is to create a symbolic link like @SlateEntropy very well pointed out in the answer below. To help with this, since version 5.3, Laravel includes a command which makes this incredibly easy to do:

php artisan storage:link

That creates a symlink from public/storage to storage/app/public for you and that's all there is to it. Now any file in /storage/app/public can be accessed via a link like:

http://somedomain.com/storage/image.jpg

If, for any reason, your can't create symbolic links (maybe you're on shared hosting, etc.) or you want to protect some files behind some access control logic, there is the alternative of having a special route that reads and serves the image. For example a simple closure route like this:

Route::get('storage/{filename}', function ($filename)
{
    $path = storage_path('public/' . $filename);

    if (!File::exists($path)) {
        abort(404);
    }

    $file = File::get($path);
    $type = File::mimeType($path);

    $response = Response::make($file, 200);
    $response->header("Content-Type", $type);

    return $response;
});

You can now access your files just as you would if you had a symlink:

http://somedomain.com/storage/image.jpg

If you're using the Intervention Image Library you can use its built in response method to make things more succinct:

Route::get('storage/{filename}', function ($filename)
{
    return Image::make(storage_path('public/' . $filename))->response();
});

WARNING

Keep in mind that by manually serving the files you're incurring a performance penalty, because you're going through the entire Laravel request lifecycle in order to read and send the file contents, which is considerably slower than having the HTTP server handle it.

I think what you want to do is this:

$(this).children('img').eq(0);

this will give you a jquery object containing the first img element, whereas

$(this).children('img')[0];

will give you the img element itself.

Solution for JPQL queries

This is supported for JPQL queries within the JPA specification.

Step 1: Declare a simple bean class

package com.path.to;

public class SurveyAnswerStatistics {
  private String answer;
  private Long   cnt;

  public SurveyAnswerStatistics(String answer, Long cnt) {
    this.answer = answer;
    this.count  = cnt;
  }
}

Step 2: Return bean instances from the repository method

public interface SurveyRepository extends CrudRepository<Survey, Long> {
    @Query("SELECT " +
           "    new com.path.to.SurveyAnswerStatistics(v.answer, COUNT(v)) " +
           "FROM " +
           "    Survey v " +
           "GROUP BY " +
           "    v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
}

Important notes

1. Make sure to provide the fully-qualified path to the bean class, including the package name. For example, if the bean class is called MyBean and it is in package com.path.to, the fully-qualified path to the bean will be com.path.to.MyBean. Simply providing MyBean will not work (unless the bean class is in the default package).
2. Make sure to call the bean class constructor using the new keyword. SELECT new com.path.to.MyBean(...) will work, whereas SELECT com.path.to.MyBean(...) will not.
3. Make sure to pass attributes in exactly the same order as that expected in the bean constructor. Attempting to pass attributes in a different order will lead to an exception.
4. Make sure the query is a valid JPA query, that is, it is not a native query. @Query("SELECT ..."), or @Query(value = "SELECT ..."), or @Query(value = "SELECT ...", nativeQuery = false) will work, whereas @Query(value = "SELECT ...", nativeQuery = true) will not work. This is because native queries are passed without modifications to the JPA provider, and are executed against the underlying RDBMS as such. Since new and com.path.to.MyBean are not valid SQL keywords, the RDBMS then throws an exception.

Solution for native queries

As noted above, the new ... syntax is a JPA-supported mechanism and works with all JPA providers. However, if the query itself is not a JPA query, that is, it is a native query, the new ... syntax will not work as the query is passed on directly to the underlying RDBMS, which does not understand the new keyword since it is not part of the SQL standard.

In situations like these, bean classes need to be replaced with Spring Data Projection interfaces.

Step 1: Declare a projection interface

package com.path.to;

public interface SurveyAnswerStatistics {
  String getAnswer();

  int getCnt();
}

Step 2: Return projected properties from the query

public interface SurveyRepository extends CrudRepository<Survey, Long> {
    @Query(nativeQuery = true, value =
           "SELECT " +
           "    v.answer AS answer, COUNT(v) AS cnt " +
           "FROM " +
           "    Survey v " +
           "GROUP BY " +
           "    v.answer")
    List<SurveyAnswerStatistics> findSurveyCount();
}

Use the SQL AS keyword to map result fields to projection properties for unambiguous mapping.

Easiest way to install MSSQL 2012 MS SQL INSTALLATION

Here i am showing the easiest way to install ms sql 2012.

My opinion is the installation will be easier with windows 8.1 rather than windows 7.

This is my personnal opinion only.

We can install in windows 7 as well.

The steps to be followed:

Download any one of the link using the following URL

http://www.microsoft.com/en-us/download/details.aspx?id=43351

SQLEXPRWT_x86_ENU.exe or SQLEXPRWT_x64_ENU.exe

http://www.microsoft.com/en-us/download/details.aspx?id=42299

SQLEXPRWT_x86_ENU.exe or SQLEXPRWT_x64_ENU.exe

Right click on .exe file and run it

We should leave everything default while installing.

During installation, there will be 2 options:

1)If you are New user,then click on new sql-server stand alone application.

2)If you have already MS SQL application then you can upgrade by using the other option.

Then accept the Licence terms and click Next.

Now you will move on to Product Updates and press next then Setup support rules.

After this Feature selection.According to me we can check all the boxes except localdb.

Next it will take you to Instance Configuration where you should select Named Instance as

"SQLEXPRESS".

Then go to Server Configuration and press next.

Now Database engine configuration:

Authentication Mode:we can click on any one that is windows authentication mode or mixed.

Windows authentication mode (default for windows).

Mixed authentication mode:then should create username and password.

Then move on Error reporting,we can move further by clicking next to install process.

Finally we can see the Complete windows by showing the products added .

We can close and run the MSSQL server.

I hope it's useful.

Ramya

You may need to call frame.repaint() as well to force the frame to actually redraw itself. I've had issues before where I tried to repaint a component and it wasn't updating what was displayed until the parent's repaint() method was called.

Xcode 6.3 didn't see my iPhone running iOS 8.3 even after a computer restart. I then restarted my iPhone and everything worked again. Love buggy software!

You can include git repository to composer.json like this:

"repositories": [
{
    "type": "package",
    "package": {
        "name": "example-package-name", //give package name to anything, must be unique
        "version": "1.0",
        "source": {
            "url": "https://github.com/example-package-name.git", //git url
            "type": "git",
            "reference": "master" //git branch-name
        }
    }
}],
"require" : {
  "example-package-name": "1.0"
}

Using awk

echo $STRING | awk -v N=$N '{print $N}'

Test

% N=3
% STRING="one two three four"
% echo $STRING | awk -v N=$N '{print $N}'

Definition: An imperative language uses a sequence of statements to determine how to reach a certain goal. These statements are said to change the state of the program as each one is executed in turn.

Examples: Java is an imperative language. For example, a program can be created to add a series of numbers:

 int total = 0;
 int number1 = 5;
 int number2 = 10;
 int number3 = 15;
 total = number1 + number2 + number3; 

Each statement changes the state of the program, from assigning values to each variable to the final addition of those values. Using a sequence of five statements the program is explicitly told how to add the numbers 5, 10 and 15 together.

Functional languages: The functional programming paradigm was explicitly created to support a pure functional approach to problem solving. Functional programming is a form of declarative programming.

Advantages of Pure Functions: The primary reason to implement functional transformations as pure functions is that pure functions are composable: that is, self-contained and stateless. These characteristics bring a number of benefits, including the following: Increased readability and maintainability. This is because each function is designed to accomplish a specific task given its arguments. The function does not rely on any external state.

Easier reiterative development. Because the code is easier to refactor, changes to design are often easier to implement. For example, suppose you write a complicated transformation, and then realize that some code is repeated several times in the transformation. If you refactor through a pure method, you can call your pure method at will without worrying about side effects.

Easier testing and debugging. Because pure functions can more easily be tested in isolation, you can write test code that calls the pure function with typical values, valid edge cases, and invalid edge cases.

For OOP People or Imperative languages:

Object-oriented languages are good when you have a fixed set of operations on things and as your code evolves, you primarily add new things. This can be accomplished by adding new classes which implement existing methods and the existing classes are left alone.

Functional languages are good when you have a fixed set of things and as your code evolves, you primarily add new operations on existing things. This can be accomplished by adding new functions which compute with existing data types and the existing functions are left alone.

Cons:

It depends on the user requirements to choose the way of programming, so there is harm only when users don’t choose the proper way.

When evolution goes the wrong way, you have problems:

• Adding a new operation to an object-oriented program may require editing many class definitions to add a new method
• Adding a new kind of thing to a functional program may require editing many function definitions to add a new case.

This timer will fire a "Hello" alertbox after 30 seconds. However, everytime you click the reset timer button it clears the timerHandle then re-sets it again. Once it's fired, the game ends.

<script type="text/javascript">
    var timerHandle = setTimeout("alert('Hello')",3000);
    function resetTimer() {
        window.clearTimeout(timerHandle);
        timerHandle = setTimeout("alert('Hello')",3000);
    }
</script>

<body>
    <button onclick="resetTimer()">Reset Timer</button>
</body>

In your controller, you are using an http scheme, but I think you should be using a ws scheme, as you are using websockets. Try to use ws://localhost:3000 in your connect function.

I wrote some simple thing:

When you initialize icheck as:

$('input').iCheck({
    checkboxClass: 'icheckbox_square-blue',
    radioClass: 'iradio_square-blue',
    increaseArea: '20%' // optional
});

Add this code under it:

$('input').on('ifChecked', function (event){
    $(this).closest("input").attr('checked', true);          
});
$('input').on('ifUnchecked', function (event) {
    $(this).closest("input").attr('checked', false);
});

After this you can easily find your original checkbox's state. I wrote this code for using icheck in gridView and accessed its state from server side by C#.

Simply find your checkBox from its id.

Just adding this answer to help Google save some punter the hours I have spent to get here. I used ILMerge on my .Net 4.0 project, without the /targetplatform option set, assuming it would be detected correctly from my main assembly. I then had complaints from users only on Windows XP aka WinXP. This now makes sense as XP will never have > .Net 4.0 installed whereas most newer OSes will. So if your XP users are having issues, see the fixes above.

You can do which python and see if its pointing to the one in virtual env.

setting the content-type to undefined would make javascript pass the header data As it is , and over writing the default angular $httpProvider header configurations. Angular $http Documentation

$http({url:url,method:"POST", headers:{'Content-Type':undefined}).then(success,failure);

Try this, it's a hack. the Position:absolute is for Chrome and trigger('change') is for IE.

var hiddenFile = $("<input type=\"file\" name=\"file\" id=\"file1\" style=\"position:absolute;left:-9999px\" />");
$('body').append(hiddenFile);

$('#aPhotoUpload').click(function () {
    hiddenFile.trigger('click');
    if ($.browser.msie)
        hiddenFile.trigger('change');
});

hiddenFile.change(function (e) {
    alert('TODO');
});

There are several methods available for setting the height of a <div> to 100%.

Method (A):

html,_x000D_
body {_x000D_
  height: 100%;_x000D_
  min-height: 100%;_x000D_
}_x000D_
.div-left {_x000D_
  height: 100%;_x000D_
  width: 50%;_x000D_
  background: green;_x000D_
}_x000D_
.div-right {_x000D_
  height: 100%;_x000D_
  width: 50%;_x000D_
  background: gray;_x000D_
}

<div class="div-left"></div>_x000D_
<div class="div-right"></div>

Method (B) using vh:

html,_x000D_
body {_x000D_
  height: 100%;_x000D_
  min-height: 100%;_x000D_
}_x000D_
.div-left {_x000D_
  height: 100vh;_x000D_
  width: 50%;_x000D_
  background: green;_x000D_
  float: left;_x000D_
}_x000D_
.div-right {_x000D_
  height: 100vh;_x000D_
  width: 50%;_x000D_
  background: gray;_x000D_
  float: right;_x000D_
}

<div class="div-left"></div>_x000D_
<div class="div-right"></div>

Method (c) using flex box:

html,_x000D_
body {_x000D_
  height: 100%;_x000D_
  min-height: 100%;_x000D_
}_x000D_
.wrapper {_x000D_

}

<div class="wrapper">_x000D_
  <div class="div-left"></div>_x000D_
  <div class="div-right"></div>_x000D_
</div>

In following solution, table occupies 100% of the parent container, no absolute sizes required. It's pure CSS, flex layout is used.

Here is how it looks:

Possible disadvantages:

• vertical scrollbar is always visible, regardless of whether it's required;
• table layout is fixed - columns do not resize according to the content width (you still can set whatever column width you want explicitly);
• there is one absolute size - the width of the scrollbar, which is about 0.9em for the browsers I was able to check.

HTML (shortened):

<div class="table-container">
    <table>
        <thead>
            <tr>
                <th>head1</th>
                <th>head2</th>
                <th>head3</th>
                <th>head4</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>content1</td>
                <td>content2</td>
                <td>content3</td>
                <td>content4</td>
            </tr>
            <tr>
                <td>content1</td>
                <td>content2</td>
                <td>content3</td>
                <td>content4</td>
            </tr>
            ...
        </tbody>
    </table>
</div>

CSS, with some decorations omitted for clarity:

.table-container {
    height: 10em;
}
table {
    display: flex;
    flex-flow: column;
    height: 100%;
    width: 100%;
}
table thead {
    /* head takes the height it requires, 
    and it's not scaled when table is resized */
    flex: 0 0 auto;
    width: calc(100% - 0.9em);
}
table tbody {
    /* body takes all the remaining available space */
    flex: 1 1 auto;
    display: block;
    overflow-y: scroll;
}
table tbody tr {
    width: 100%;
}
table thead, table tbody tr {
    display: table;
    table-layout: fixed;
}

full code on jsfiddle

Same code in LESS so you can mix it in:

.table-scrollable() {
  @scrollbar-width: 0.9em;
  display: flex;
  flex-flow: column;

  thead,
  tbody tr {
    display: table;
    table-layout: fixed;
  }

  thead {
    flex: 0 0 auto;
    width: ~"calc(100% - @{scrollbar-width})";
  }

  tbody {
    display: block;
    flex: 1 1 auto;
    overflow-y: scroll;

    tr {
      width: 100%;
    }
  }
}

The & means that the function accepts the address (or reference) to a variable, instead of the value of the variable.

For example, note the difference between this:

void af(int& g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

And this (without the &):

void af(int g)
{
    g++;
    cout<<g;
}

int main()
{
    int g = 123;
    cout << g;
    af(g);
    cout << g;
    return 0;
}

Although ObjectMapper is thread safe, I would strongly discourage from declaring it as a static variable, especially in multithreaded application. Not even because it is a bad practice, but because you are running a heavy risk of deadlocking. I am telling it from my own experience. I created an application with 4 identical threads that were getting and processing JSON data from web services. My application was frequently stalling on the following command, according to the thread dump:

Map aPage = mapper.readValue(reader, Map.class);

Beside that, performance was not good. When I replaced static variable with the instance based variable, stalling disappeared and performance quadrupled. I.e. 2.4 millions JSON documents were processed in 40min.56sec., instead of 2.5 hours previously.

In My example call add function from button click event and then get value from form control's and call function generateTable.
In generateTable Function check first Table is Generaed or not. If table is undefined then call generateHeader Funtion and Generate Header and then call addToRow function for adding new row in table.

<input type="button" class="custom-rounded-bttn bttn-save" value="Add" id="btnAdd" onclick="add()">


<div class="row">
    <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
        <div class="dataGridForItem">
        </div>
    </div>
</div>

//Call Function From Button click Event

var counts = 1;
function add(){ 
    var Weightage = $('#Weightage').val();
    var ItemName = $('#ItemName option:selected').text();  
    var ItemNamenum = $('#ItemName').val();
    generateTable(Weightage,ItemName,ItemNamenum);
     $('#Weightage').val('');
     $('#ItemName').val(-1);
     return true;
 } 


function generateTable(Weightage,ItemName,ItemNamenum){
    var tableHtml = '';
    if($("#rDataTable").html() == undefined){
        tableHtml = generateHeader();
    }else{
        tableHtml = $("#rDataTable");
    } 
    var temp = $("<div/>");
    var row = addToRow(Weightage,ItemName,ItemNamenum);
    $(temp).append($(row));
    $("#dataGridForItem").html($(tableHtml).append($(temp).html()));
}


//Generate Header


function generateHeader(){
        var html = "<table id='rDataTable' class='table table-striped'>";
        html+="<tr class=''>";
        html+="<td class='tb-heading ui-state-default'>"+'Sr.No'+"</td>";
        html+="<td class='tb-heading ui-state-default'>"+'Item Name'+"</td>";
        html+="<td class='tb-heading ui-state-default'>"+'Weightage'+"</td>";
        html+="</tr></table>";
        return html; 
}

//Add New Row


function addToRow(Weightage,ItemName,ItemNamenum){
    var html="<tr class='trObj'>";
    html+="<td>"+counts+"</td>";
    html+="<td>"+ItemName+"</td>";
    html+="<td>"+Weightage+"</td>";
    html+="</tr>";
    counts++;
    return html;
}

Use beginUpdates and endUpdates to insert a new cell when the button clicked.

As @vadian said in comment, begin/endUpdates has no effect for a single insert/delete/move operation

First of all, append data in your tableview array

Yourarray.append([labeltext])  

Then update your table and insert a new row

// Update Table Data
tblname.beginUpdates()
tblname.insertRowsAtIndexPaths([
NSIndexPath(forRow: Yourarray.count-1, inSection: 0)], withRowAnimation: .Automatic)
tblname.endUpdates()

This inserts cell and doesn't need to reload the whole table but if you get any problem with this, you can also use tableview.reloadData()

Swift 3.0

tableView.beginUpdates()
tableView.insertRows(at: [IndexPath(row: yourArray.count-1, section: 0)], with: .automatic)
tableView.endUpdates()

Objective-C

[self.tblname beginUpdates];
NSArray *arr = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:Yourarray.count-1 inSection:0]];
[self.tblname insertRowsAtIndexPaths:arr withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tblname endUpdates];

Change ng-disabled="!contractTypeValid" to [disabled]="!contractTypeValid"

git 1.9.3 or later: use __git_ps1

Git provides a shell script called git-prompt.sh, which includes a function __git_ps1 that

prints text to add to bash PS1 prompt (includes branch name)

Its most basic usage is:

$ __git_ps1
(master)

It also takes an optional format string:

$ __git_ps1 'git:[%s]'
git:[master]

How to Get It

First, copy the file to somewhere (e.g. ~/.git-prompt.sh).

Option 1: use an existing copy on your filesystem. Example (Mac OS X 10.15):

$ find / -name 'git-prompt.sh' -type f -print -quit 2>/dev/null
/Library/Developer/CommandLineTools/usr/share/git-core/git-prompt.sh

Option 2: Pull the script from GitHub.

Next, add the following line to your .bashrc/.zshrc:

source ~/.git-prompt.sh

Finally, change your PS1 to call __git_ps1 as command-substitution:

Bash:

PS1='[\u@\h \W$(__git_ps1 " (%s)")]\$ '

Zsh:

setopt PROMPT_SUBST ; PS1='[%n@%m %c$(__git_ps1 " (%s)")]\$ '

git < 1.9.3

But note that only git 1.9.3 (May 2014) or later allows you to safely display that branch name(!)

See commit 8976500 by Richard Hansen (richardhansen):

Both bash and zsh subject the value of PS1 to parameter expansion, command substitution, and arithmetic expansion.

Rather than include the raw, unescaped branch name in PS1 when running in two- or three-argument mode, construct PS1 to reference a variable that holds the branch name.

Because the shells do not recursively expand, this avoids arbitrary code execution by specially-crafted branch names such as

'$(IFS=_;cmd=sudo_rm_-rf_/;$cmd)'.

What devious mind would name a branch like that? ;) (Beside a Mom as in xkcd)

More Examples

still_dreaming_1 reports in the comments:

This seems to work great if you want a color prompt with xterm (in my .bashrc):

PS1='\[\e]0;\u@\h: \w\a\]\n${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\03??3[01;34m\]\w\[\033[00m\]$(__git_ps1)\$ ' 

Everything is a different color, including the branch.

In in Linux Mint 17.3 Cinnamon 64-bit:

PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[00m\]$(__git_ps1) \$ ' 

//This will sort your array
function SortByName(a, b){
  var aName = a.name.toLowerCase();
  var bName = b.name.toLowerCase(); 
  return ((aName < bName) ? -1 : ((aName > bName) ? 1 : 0));
}

array.sort(SortByName);

$replace_str = array('"', "'", ",");
$FileName = str_replace($replace_str, "", $UserInput);

There's no difference between the file extensions, and they are used interchangeably. I guess the 3-letter version stems from the DOS era...

However, there are different "flavors" of JPEG files. Most notably the JFIF standard and the EXIF standard. Most often these just use .jpg or .jpeg as file extensions, JFIF sometimes uses .jif or .jfif.

You can use number.toString(10.1):

console.log(Number.MAX_VALUE.toString(10.1));

Note: This currently works in Chrome, but not in Firefox. The specification says the radix has to be an integer, so this results in unreliable behavior.

Does this do what you want?

.childRightCol, .childLeftCol
{
    display: inline-block;
    width: 50%;
    margin: 0;
    padding: 0;
    vertical-align: top;
}

From the netstat output you can see the process is listening on address 127.0.0.1

tcp        0      0 127.0.0.1:9000          0.0.0.0:*  ...

from the exception message you can see that it tries to connect to address 127.0.1.1

java.net.ConnectException: Call From marta-komputer/127.0.1.1 to localhost:9000 failed ...

further in the exception it's mentionend

For more details see:  http://wiki.apache.org/hadoop/ConnectionRefused

on this page you find

Check that there isn't an entry for your hostname mapped to 127.0.0.1 or 127.0.1.1 in /etc/hosts (Ubuntu is notorious for this)

so the conclusion is to remove this line in your /etc/hosts

127.0.1.1       marta-komputer

modify() in your example is a private function, that won't be accessible from anywhere but within your A, B or C definition. You would need to declare it as

this.modify = function(){}

C has no reference to its parents, unless you pass it to C. If C is set up to inherit from A or B, it will inherit its public methods (not its private functions like you have modify() defined). Once C inherits methods from its parent, you can override the inherited methods.

I found a solution that worked for me. I downgraded from the latest guzzle to version ~4.0 and it worked.

In composer.json add "guzzlehttp/guzzle": "~4.0"

Hope it helps someone

You didn't bind all your bindings here

$sql = "SELECT SQL_CALC_FOUND_ROWS *, UNIX_TIMESTAMP(publicationDate) AS publicationDate     FROM comments WHERE articleid = :art 
ORDER BY " . mysqli_escape_string($order) . " LIMIT :numRows";

$st = $conn->prepare( $sql );
$st->bindValue( ":art", $art, PDO::PARAM_INT );

You've declared a binding called :numRows but you never actually bind anything to it.

UPDATE 2019: I keep getting upvotes on this and that reminded me of another suggestion

Double quotes are string interpolation in PHP, so if you're going to use variables in a double quotes string, it's pointless to use the concat operator. On the flip side, single quotes are not string interpolation, so if you've only got like one variable at the end of a string it can make sense, or just use it for the whole string.

In fact, there's a micro op available here since the interpreter doesn't care about parsing the string for variables. The boost is nearly unnoticable and totally ignorable on a small scale. However, in a very large application, especially good old legacy monoliths, there can be a noticeable performance increase if strings are used like this. (and IMO, it's easier to read anyway)

I was able to change the selected view color like this. I think this is the SIMPLE WAY (because you don't have to create instance of layouts and variables.

MAKE SURE YOU DONT GIVE ANY BACKGROUND COLOR INSIDE YOUR RECYCLER VIEW's TAG.

holder.itemView.setBackgroundColor(Color.parseColor("#8DFFFFFF"));

onBindViewHolder() method is given below

@Override
public void onBindViewHolder(@NonNull final MyViewHolder holder, final int position) {

        holder.item_1.setText(list_items.get(position).item_1);
        holder.item_2.setText(list_items.get(position).item_2);
        holder.select_cb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                if (isChecked){

                    holder.itemView.setBackgroundColor(Color.parseColor("#8DFFFFFF"));
                }else {

                    holder.itemView.setBackgroundColor(Color.parseColor("#FFFFFF"));
                }
            }
        });
}

In all honesty, eval(repr(obj)) is never used. If you find yourself using it, you should stop, because eval is dangerous, and strings are a very inefficient way to serialize your objects (use pickle instead).

Therefore, I would recommend setting __repr__ = __str__. The reason is that str(list) calls repr on the elements (I consider this to be one of the biggest design flaws of Python that was not addressed by Python 3). An actual repr will probably not be very helpful as the output of print [your, objects].

To qualify this, in my experience, the most useful use case of the repr function is to put a string inside another string (using string formatting). This way, you don't have to worry about escaping quotes or anything. But note that there is no eval happening here.

In Xcode 10 the OS_ACTIVITY_MODE variable with disable (or default) value also turns off the NSLog no matter what.

So if you want to get rid of the console noise but not of your own logs, you could try the good old printf("") instead of the NSLog since it is not affected by the OS_ACTIVITY_MODE = disable.

But better check out the new os_log API here.

These are several ways to apply style to an element. Try any one of the examples below:

1. document.getElementById('div_register').className = 'wide';
  /* CSS */ .wide{width:500px;}
2. document.getElementById('div_register').setAttribute('class','wide');
3. document.getElementById('div_register').style.width = '500px';

YES, you can, because undefined is defined as undefined.

console.log(
   /*global.*/undefined === window['undefined'] &&
   /*global.*/undefined === (function(){})() &&
   window['undefined']  === (function(){})()
) //true

your case:

test("value1", undefined, "value2")

you can also create your own undefined variable:

Object.defineProperty(this, 'u', {value : undefined});
console.log(u); //undefined

First, you should create an array check[n] where n is the number of elements of the array you want to make duplicate-free and set the value of every element(of the check array) equal to 1. Using a for loop traverse the array with the duplicates, say its name is arr, and in the for-loop write this :

{
    if (check[arr[i]] != 1) {
        arr[i] = 0;
    }
    else {
        check[arr[i]] = 0;
    }
}

With that, you set every duplicate equal to zero. So the only thing is left to do is to traverse the arr array and print everything it's not equal to zero. The order stays and it takes linear time (3*n).

You can add it by appending a Series to the dataframe as follows. I am assuming by blank you mean you want to add a row containing only "Nan". You can first create a Series object with Nan. Make sure you specify the columns while defining 'Series' object in the -Index parameter. The you can append it to the DF. Hope it helps!

from numpy import nan as Nan
import pandas as pd

>>> df1 = pd.DataFrame({'A': ['A0', 'A1', 'A2', 'A3'],
...                     'B': ['B0', 'B1', 'B2', 'B3'],
...                     'C': ['C0', 'C1', 'C2', 'C3'],
...                     'D': ['D0', 'D1', 'D2', 'D3']},
...                     index=[0, 1, 2, 3])

>>> s2 = pd.Series([Nan,Nan,Nan,Nan], index=['A', 'B', 'C', 'D'])
>>> result = df1.append(s2)
>>> result
     A    B    C    D
0   A0   B0   C0   D0
1   A1   B1   C1   D1
2   A2   B2   C2   D2
3   A3   B3   C3   D3
4  NaN  NaN  NaN  NaN

First of all, I suggest to modify a bit your sql query:

 select * from shift 
 where shift.shiftid not in (select employeeshift.shiftid from employeeshift 
                             where employeeshift.empid = 57);

This query provides same functionality. If you want to get the same result with LINQ, you can try this code:

//Variable dc has DataContext type here
//Here we get list of ShiftIDs from employeeshift table
List<int> empShiftIds = dc.employeeshift.Where(p => p.EmpID = 57).Select(s => s.ShiftID).ToList();

//Here we get the list of our shifts
List<shift> shifts = dc.shift.Where(p => !empShiftIds.Contains(p.ShiftId)).ToList();

Check with your firewall expert. They open the firewall for PROD servers so there is no need to use the Proxy.

Thanks your tip helped me solve my problem:

Had to to set the Credentials in two locations to get past the 407 error:

HttpWebRequest webRequest = WebRequest.Create(uirTradeStream) as HttpWebRequest;
webRequest.Proxy = WebRequest.DefaultWebProxy;
webRequest.Credentials = new NetworkCredential("user", "password", "domain");
webRequest.Proxy.Credentials = new NetworkCredential("user", "password", "domain");

and voila!

How about this:

When the page first loads, do this:

var myTable = document.getElementById("myTable");
myTable.oldHTML=myTable.innerHTML;

Then when you want to clear the table:

myTable.innerHTML=myTable.oldHTML;

The result will be your header row(s) if that's all you started with, the performance is dramatically faster than looping.

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn't seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.

The max size for a column of type NVARCHAR(MAX) is 2 GByte of storage.

Since NVARCHAR uses 2 bytes per character, that's approx. 1 billion characters.

Leo Tolstoj's War and Peace is a 1'440 page book, containing about 600'000 words - so that might be 6 million characters - well rounded up. So you could stick about 166 copies of the entire War and Peace book into each NVARCHAR(MAX) column.

Is that enough space for your needs? :-)

I had a mismatch between projects: one with multi-byte character set, the other with Unicode. Correcting these to agree on Unicode corrected the problem.

Such unexpected problems can appear when you copy the code from a web page or email and the text contains unprintable characters like individual CR or LF and non-breaking spaces.

%W and %w allow you to create an Array of strings without using quotes and commas.

As of 2014, you can trigger the click on a <a/> tag. However, for security reasons, you have to do it in a click event handler, or the browser will tag it as a popup (some other events may allow you to safely trigger the opening).

jsFiddle

try

List<TheUser> friends = jsonSerializer.Deserialize<List<TheUser>>(response);

I guess this is what you need to look at: use onSizeChanged() of your view. Here is an EXTENDED code snippet on how to use onSizeChanged() to get your layout's or view's height and width dynamically http://syedrakibalhasan.blogspot.com/2011/02/how-to-get-width-and-height-dimensions.html

The following function will work in JDK version 1.5 and above.

One of the best component of android architechure introduce by google will fulfill your all the requirement that is ViewModel.

That is designed to store and manage UI related data in lifecycle way plus that will allow data to survive as screen rotates

class MyViewModel : ViewModel() {

Please refer this:https://developer.android.com/topic/libraries/architecture/viewmodel

Edit: I've since been using ng-dialog from http://likeastore.github.io/ngDialog which is flexible and doesn't have any dependencies.

A couple of things:

• You need to set the video bitrate. I have never used minrate and maxrate so I don't know how exactly they work, but by setting the bitrate using the -b switch, I am able to get high quality video. You need to come up with a bitrate that offers a good tradeoff between compression and video quality. You may have to experiment with this because it all depends on the frame size, frame rate and the amount of motion in the content of your video. Keep in mind that DVD tends to be around 4-5 Mbit/s on average for 720x480, so I usually start from there and decide whether I need more or less and then just experiment. For example, you could add -b 5000k to the command line to get more or less DVD video bitrate.

• You need to specify a video codec. If you don't, ffmpeg will default to MPEG-1 which is quite old and does not provide near the amount of compression as MPEG-4 or H.264. If your ffmpeg version is built with libx264 support, you can specify -vcodec libx264 as part of the command line. Otherwise -vcodec mpeg4 will also do a better job than MPEG-1, but not as well as x264.

• There are a lot of other advanced options that will help you squeeze out the best quality at the lowest bitrates. Take a look here for some examples.

It's suprising that no one mentioned about run-one. I've solved my problem with this.

 apt-get install run-one

then add run-one before your crontab script

Check out this askubuntu SE answer. You can find link to a detailed information there as well.

All numbers in Lua are floats (edit: Lua 5.2 or less). If you truly want to convert to an "int" (or at least replicate this behavior), you can do this:

local function ToInteger(number)
    return math.floor(tonumber(number) or error("Could not cast '" .. tostring(number) .. "' to number.'"))
end

In which case you explicitly convert the string (or really, whatever it is) into a number, and then truncate the number like an (int) cast would do in Java.

Edit: This still works in Lua 5.3, even thought Lua 5.3 has real integers, as math.floor() returns an integer, whereas an operator such as number // 1 will still return a float if number is a float.

Don't forget that the status bar's frame will be in the screen's coordinate space! If you launch in landscape mode, you may find that width and height are swapped. I strongly recommend that you use this version of the code instead if you support landscape orientations:

CGRect statusBarFrame = [self.window convertRect:[UIApplication sharedApplication].statusBarFrame toView:view];

You can then read statusBarFrame's height property directly. 'View' in this instance should be the view in which you wish to make use of the measurements, most likely the application window's root view controller.

Incidentally, not only may the status bar be taller during phone calls, it can also be zero if the status bar has been deliberately hidden.

All three template options - <%@include>, <jsp:include> and <%@tag> are valid, and all three cover different use cases.

With <@include>, the JSP parser in-lines the content of the included file into the JSP before compilation (similar to a C #include). You'd use this option with simple, static content: for example, if you wanted to include header, footer, or navigation elements into every page in your web-app. The included content becomes part of the compiled JSP and there's no extra cost at runtime.

<jsp:include> (and JSTL's <c:import>, which is similar and even more powerful) are best suited to dynamic content. Use these when you need to include content from another URL, local or remote; when the resource you're including is itself dynamic; or when the included content uses variables or bean definitions that conflict with the including page. <c:import> also allows you to store the included text in a variable, which you can further manipulate or reuse. Both these incur an additional runtime cost for the dispatch: this is minimal, but you need to be aware that the dynamic include is not "free".

Use tag files when you want to create reusable user interface components. If you have a List of Widgets, say, and you want to iterate over the Widgets and display properties of each (in a table, or in a form), you'd create a tag. Tags can take arguments, using <%@tag attribute> and these arguments can be either mandatory or optional - somewhat like method parameters.

Tag files are a simpler, JSP-based mechanism of writing tag libraries, which (pre JSP 2.0) you had to write using Java code. It's a lot cleaner to write JSP tag files when there's a lot of rendering to do in the tag: you don't need to mix Java and HTML code as you'd have to do if you wrote your tags in Java.

If you are sitting at the merge commit then this shows the diffs:

git diff HEAD~1..HEAD

If you're not at the merge commit then just replace HEAD with the merge commit. This method seems like the simplest and most intuitive.

The image you're using is Alpine based, so you can't use apt-get because it's Ubuntu's package manager.

To fix this just use:

apk update and apk add
