I used this for radio's:

    if (element.prop("type") === "checkbox" || element.prop("type") === "radio") {
        error.appendTo(element.parent().parent());
    }
    else if (element.parent(".input-group").length) {
        error.insertAfter(element.parent());
    }
    else {
        error.insertAfter(element);
    }

this way the error is displayed under last radio option.

If you have code in one subdirectory dependent on code in another subdirectory, you are probably better off with a single makefile at top-level.

See Recursive Make Considered Harmful for the full rationale, but basically you want make to have the full information it needs to decide whether or not a file needs to be rebuilt, and it won't have that if you only tell it about a third of your project.

In addition to Thevs answer:

var o = {};
alert($.toJSON(o)=='{}'); // true

var o = {a:1};
alert($.toJSON(o)=='{}'); // false

it's jquery + jquery.json

Use following in your CSS

div {
    -webkit-transform: rotate(90deg); /* Safari and Chrome */
    -moz-transform: rotate(90deg);   /* Firefox */
    -ms-transform: rotate(90deg);   /* IE 9 */
    -o-transform: rotate(90deg);   /* Opera */
    transform: rotate(90deg);
} 

If you happen to work in a Unix environment, the expand command is what you need:

The answer I want to give is "use collections.ChainMap", but I just discovered that it was only added in Python 3.3: https://docs.python.org/3.3/library/collections.html#chainmap-objects

You can try to crib the class from the 3.3 source though: http://hg.python.org/cpython/file/3.3/Lib/collections/init.py#l763

Here is a less feature-full Python 2.x compatible version (same author): http://code.activestate.com/recipes/305268-chained-map-lookups/

Instead of expanding/overwriting one dictionary with another using dict.merge, or creating an additional copy merging both, you create a lookup chain that searches both in order. Because it doesn't duplicate the mappings it wraps ChainMap uses very little memory, and sees later modifications to any sub-mapping. Because order matters you can also use the chain to layer defaults (i.e. user prefs > config > env).

In my particular case, I had a similar error on a legacy website used in my organization. To solve the issue, I had to list the website a a "Trusted site".

To do so:

• Click the Tools button, and then Internet options.
• Go on the Security tab.
• Click on Trusted sites and then on the sites button.
• Enter the url of the website and click on Add.

I'm leaving this here in the remote case it will help someone.

Instead of using URI segments you should do this:

$this->router->fetch_class(); // class = controller
$this->router->fetch_method();

That way you know you are always using the correct values even if you are behind a routed URL, in a sub-domain, etc.

Check if the service starting code is correct,

ServiceBase[] ServicesToRun;
ServicesToRun = new ServiceBase[] 
{ 
    new WinsowsServiceToRun() 
};
ServiceBase.Run(ServicesToRun);

Also, remove any debug codes. ie,

  #If Debug
         ...
         ...
         ...
        #else
         ...
         ...
        #endif

Solution 1:
In Xcode, go to File ? Project/Workspace settings.
? Change the build system to Legacy Build system.

Solution 2 :
Open target ? Build phases ? Copy Bundle Resources ? remove info.plist from there. ? you will have to remove the plist from the Extensions too (if any).

Solution 3:
If you use CocoaPods you may want to try deintegrate the pods and install again. Commands:

1) pod deintegrate
2) pod install

If using @Rule, the exception set is applied to all the test methods in the Test class.

You can do this ( where data-x has the appropriate display:xxxx set ):

<!-- TH -->
<div data-tr>
    <div data-th style="width:25%">TH</div>
    <div data-th style="width:50%">

         <div data-table style="width:100%">
             <div data-tr>
                 <div data-th style="width:25%">TH</div>
                 <div data-th style="width:25%">TH</div>

                 <div data-th style="width:25%">TH</div>
             </div>
         </div>

    </div>
    <div data-th style="width:25%">TH</div>
</div>


<!-- TD -->
<div data-tr>
    <div data-td style="width:25%">TD</div>
    <div data-th style="width:50%">

         <div data-table style="width:100%">
             <div data-tr>
                 <div data-td style="width:25%">TD</div>
                 <div data-td style="width:25%">TD</div>
                 <div data-td style="width:25%">TD</div>
                 <div data-td style="width:25%">TD</div>
             </div>
             <div data-tr>
                 ...
             </div>
         </div>

    </div>
    <div data-td style="width:25%">TD</div>

Just give the Image "position: relative" and it will work

Try this method:

1. Insert a column to the left of the cells to be sorted.
2. Assume cols B:G are to be sorted based on B
3. Copy col B
4. Paste values into col A
5. Highlight cols B:G
6. Replace = signs with # signs
7. Sort cols A:G based on A
8. Highlight cols B:G
9. replace # signs with = signs
10. Delete col A.
11. Voila!

Here is the latest sample of Google's geocode Web Service

https://maps.googleapis.com/maps/api/geocode/json?latlng=40.714224,-73.961452&key=YOUR_API_KEY

Simply change the YOUR_API_KEY to the API key you get from Google Geocoding API

P/S: Geocoding API is under Places NOT Maps ;)

You could extend the "string" class to let you return a limited string.

using System;

namespace ConsoleApplication1
{
   class Program
   {
      static void Main(string[] args)
      {
         // since specified strings are treated on the fly as string objects...
         string limit5 = "The quick brown fox jumped over the lazy dog.".LimitLength(5);
         string limit10 = "The quick brown fox jumped over the lazy dog.".LimitLength(10);
         // this line should return us the entire contents of the test string
         string limit100 = "The quick brown fox jumped over the lazy dog.".LimitLength(100);

         Console.WriteLine("limit5   - {0}", limit5);
         Console.WriteLine("limit10  - {0}", limit10);
         Console.WriteLine("limit100 - {0}", limit100);

         Console.ReadLine();
      }
   }

   public static class StringExtensions
   {
      /// <summary>
      /// Method that limits the length of text to a defined length.
      /// </summary>
      /// <param name="source">The source text.</param>
      /// <param name="maxLength">The maximum limit of the string to return.</param>
      public static string LimitLength(this string source, int maxLength)
      {
         if (source.Length <= maxLength)
         {
            return source;
         }

         return source.Substring(0, maxLength);
      }
   }
}

Result:

limit5 - The q
limit10 - The quick
limit100 - The quick brown fox jumped over the lazy dog.

Use direct cast string s = (string) o; if in the logical context of your app string is the only valid type. With this approach, you will get InvalidCastException and implement the principle of Fail-fast. Your logic will be protected from passing the invalid type further or get NullReferenceException if used as operator.

If the logic expects several different types cast string s = o as string; and check it on null or use is operator.

New cool feature have appeared in C# 7.0 to simplify cast and check is a Pattern matching:

if(o is string s)
{
  // Use string variable s
}

or

switch (o)
{
  case int i:
     // Use int variable i
     break;
  case string s:
     // Use string variable s
     break;
 }

I like to use zip(*iterable) (which is the piece of code you're looking for) in my programs as so:

def unzip(iterable):
    return zip(*iterable)

I find unzip more readable.

Git submodules are a little bit strange - they're always in "detached head" mode - they don't update to the latest commit on a branch like you might expect.

This does make some sense when you think about it, though. Let's say I create repository foo with submodule bar. I push my changes and tell you to check out commit a7402be from repository foo.

Then imagine that someone commits a change to repository bar before you can make your clone.

When you check out commit a7402be from repository foo, you expect to get the same code I pushed. That's why submodules don't update until you tell them to explicitly and then make a new commit.

Personally I think submodules are the most confusing part of Git. There are lots of places that can explain submodules better than I can. I recommend Pro Git by Scott Chacon.

I resolved with the code below:

set escape on

and put a \ beside & in the left 'value_\&_intert'

I think Google Open Sources Java To Objective-C Translator will make it possiblöe to develop in Java for iOS https://code.google.com/p/j2objc/

On events "Enter" (for example: press Tab key) or "First Click" all text will be selected. dotNET 4.0

public static class TbHelper
{
    // Method for use
    public static void SelectAllTextOnEnter(TextBox Tb)
    {
        Tb.Enter += new EventHandler(Tb_Enter);
        Tb.Click += new EventHandler(Tb_Click);
    }

    private static TextBox LastTb;

    private static void Tb_Enter(object sender, EventArgs e)
    {
        var Tb = (TextBox)sender;
        Tb.SelectAll();
        LastTb = Tb;
    }

    private static void Tb_Click(object sender, EventArgs e)
    {
        var Tb = (TextBox)sender;
        if (LastTb == Tb)
        {
            Tb.SelectAll();
            LastTb = null;
        }
    }
}

There's no built-in way, you'll have to loop over all of them:

function setAll(a, v) {
    var i, n = a.length;
    for (i = 0; i < n; ++i) {
        a[i] = v;
    }
}

http://jsfiddle.net/alnitak/xG88A/

If you really want, do this:

Array.prototype.setAll = function(v) {
    var i, n = this.length;
    for (i = 0; i < n; ++i) {
        this[i] = v;
    }
};

and then you could actually do cool.setAll(42) (see http://jsfiddle.net/alnitak/ee3hb/).

Some people frown upon extending the prototype of built-in types, though.

EDIT ES5 introduced a way to safely extend both Object.prototype and Array.prototype without breaking for ... in ... enumeration:

Object.defineProperty(Array.prototype, 'setAll', {
    value: function(v) {
        ...
    }
});

EDIT 2 In ES6 draft there's also now Array.prototype.fill, usage cool.fill(42)

You need to install a plugin, There is a free one from the eclipse foundation called the Web Tools Platform. It has all the development functionality that you'll need.

You can get the Java EE Edition of eclipse with has it pre-installed.

To create and run your first servlet:

1. New... Project... Dynamic Web Project.
2. Right click the project... New Servlet.
3. Write some code in the doGet() method.
4. Find the servers view in the Java EE perspective, it's usually one of the tabs at the bottom.
5. Right click in there and select new Server.
6. Select Tomcat X.X and a wizard will point you to finding the installation.
7. Right click the server you just created and select Add and Remove... and add your created web project.
8. Right click your servlet and select Run > Run on Server...

That should do it for you. You can use ant to build here if that's what you'd like but eclipse will actually do the build and automatically deploy the changes to the server. With Tomcat you might have to restart it every now and again depending on the change.

As per the hibernate docs here,

Connection connection()

Deprecated. (scheduled for removal in 4.x). Replacement depends on need; for doing direct JDBC stuff use doWork(org.hibernate.jdbc.Work) ...

Use Hibernate Work API instead:

Session session = entityManager.unwrap(Session.class);
session.doWork(new Work() {

    @Override
    public void execute(Connection connection) throws SQLException {
        // do whatever you need to do with the connection
    }
});

When you use Fabric for public beta releases (signed with prod config), DON'T USE Google Play App Signing. You will must after build two signed apks!

When you distribute to more play stores (samsung, amazon, xiaomi, ...) you will must again build two signed apks.

So be really carefull with Google Play App Signing.

It's not possible to revert it :/ and Google Play did not after accept apks signed with production key. After enable Google Play App Signing only upload key is accepted...

It really complicate CI distribution...

Heres a more generic implementation:

This technique still uses index to keep with Swift's standards, and imply a full Character.

extension String
{
    func subString <R> (_ range: R) -> String? where R : RangeExpression, String.Index == R.Bound
    {
        return String(self[range])
    }

    func index(at: Int) -> Index
    {
        return self.index(self.startIndex, offsetBy: at)
    }
}

To sub string from the 3rd character:

let item = "Fred looks funny"
item.subString(item.index(at: 2)...) // "ed looks funny"

I've used camel subString to indicate it returns a String and not a Substring.

this is one:

ls -l . | egrep -c '^-'

Note:

ls -1 | wc -l

Which means: ls: list files in dir

-1: (that's a ONE) only one entry per line. Change it to -1a if you want hidden files too

|: pipe output onto...

wc: "wordcount"

-l: count lines.

In my case, IIS was fine but.. uh.. all the files in the folder except web.config had been deleted (a manual deployment half-done on a test site).

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

Pass your arguments in constructor itself.

Process process = new ProcessBuilder("C:\\PathToExe\\MyExe.exe","param1","param2").start();

The __del__ method (note spelling!) is called when your object is finally destroyed. Technically speaking (in cPython) that is when there are no more references to your object, ie when it goes out of scope.

If you want to delete your object and thus call the __del__ method use

del obj1

which will delete the object (provided there weren't any other references to it).

I suggest you write a small class like this

class T:
    def __del__(self):
        print "deleted"

And investigate in the python interpreter, eg

>>> a = T()
>>> del a
deleted
>>> a = T()
>>> b = a
>>> del b
>>> del a
deleted
>>> def fn():
...     a = T()
...     print "exiting fn"
...
>>> fn()
exiting fn
deleted
>>>   

Note that jython and ironpython have different rules as to exactly when the object is deleted and __del__ is called. It isn't considered good practice to use __del__ though because of this and the fact that the object and its environment may be in an unknown state when it is called. It isn't absolutely guaranteed __del__ will be called either - the interpreter can exit in various ways without deleteting all objects.

You cannot straightly query mongodb collections by date components like day or month. But its possible by using the special $where javascript expression

db.mydatabase.mycollection.find({$where : function() { return this.date.getMonth() == 11} })

or simply

db.mydatabase.mycollection.find({$where : 'return this.date.getMonth() == 11'})

(But i prefer the first one)

Check out the below shell commands to get the parts of date

>date = ISODate("2011-09-25T10:12:34Z")
> date.getYear()
111
> date.getMonth()
8
> date.getdate()
25

EDIT:

Use $where only if you have no other choice. It comes with the performance problems. Please check out the below comments by @kamaradclimber and @dcrosta. I will let this post open so the other folks get the facts about it.

and check out the link $where Clauses and Functions in Queries for more info

You should not wrap JavaScript expressions in quotes.

<option data-img-src={this.props.imageUrl} value="1">{this.props.title}</option>

So,. I had this issue,. except I got [object object]

I'm sure you could do this with recursion but this worked for me:

Here is what I did in my console:

var object_that_is_not_shallow = $("all_obects_with_this_class_name");
var str = '';
object_that_is_not_shallow.map(function(_,e){
    str += $(e).html();
});
copy(str);

Then paste into your editor.

import sys
sys.exit(1)

Sleep meaning that thread is do nothing. Time is too large beacuse anthor thread query,but not disconnect server, default wait_timeout=28800;so you can set values smaller,eg 10. also you can kill the thread.

If you are using virtualenv, it is not as trivial to get the driver using the installer. What you can do then: install it as described by Devon. Then copy over cx_Oracle.pyd and the cx_Oracle-XXX.egg-info folder from Python\Lib\site-packages into the Lib\site-packages from your virtual env. Of course, also here, architecture and version are important.

I'm not familiar with PHP, but I think String.split is Java equivalent to PHP explode. As for implode, standart library does not provide such functionality. You just iterate over your array and build string using StringBuilder/StringBuffer. Or you can try excellent Google Guava Splitter and Joiner or split/join methods from Apache Commons StringUtils.

As per dart 2.6

The optional onError parameter of int.parse is deprecated. Therefore, you should use int.tryParse instead.

Note: The same applies to double.parse. Therefore, use double.tryParse instead.

  /**
   * ...
   *
   * The [onError] parameter is deprecated and will be removed.
   * Instead of `int.parse(string, onError: (string) => ...)`,
   * you should use `int.tryParse(string) ?? (...)`.
   *
   * ...
   */
  external static int parse(String source, {int radix, @deprecated int onError(String source)});

The difference is that int.tryParse returns null if the source string is invalid.

  /**
   * Parse [source] as a, possibly signed, integer literal and return its value.
   *
   * Like [parse] except that this function returns `null` where a
   * similar call to [parse] would throw a [FormatException],
   * and the [source] must still not be `null`.
   */
  external static int tryParse(String source, {int radix});

So, in your case it should look like:

// Valid source value
int parsedValue1 = int.tryParse('12345');
print(parsedValue1); // 12345

// Error handling
int parsedValue2 = int.tryParse('');
if (parsedValue2 == null) {
  print(parsedValue2); // null
  //
  // handle the error here ...
  //
}

I also wanted to clarify that if you have complex url parameters to build, you will need to build them manually. ie if your query is example.com/?latlng=-37,147, instead of providing the lat and lng values individually, you will need to build the latlng string externally, then provide it as a parameter, ie:

public interface LocationService {    
    @GET("/example/")
    void getLocation(@Query(value="latlng", encoded=true) String latlng);
}

Note the encoded=true is necessary, otherwise retrofit will encode the comma in the string parameter. Usage:

String latlng = location.getLatitude() + "," + location.getLongitude();
service.getLocation(latlng);

maybe u want to provide the same width and height for 2 container

Container(
            width: size.width * 0.30, height: size.height * 0.4,
            alignment: Alignment.center,
            decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(6)
            ),
            child: Center(
              child: Text(categoryName, textAlign: TextAlign.center, style: TextStyle(
                fontWeight: FontWeight.bold,
                fontSize: 17,
                color: Colors.white,
              ),),
            ),

I've used the Visual Studio extension "Full Rename Project" to successfully rename projects in an ASP.NET Core 2 solution.

I used ReSharper then to adjust the namespace (right click on project, refactor, adjust namespaces...)

Sharing my solution here, based on Chris' answer. Hope it can help others.

I needed to dynamically append child elements into my JSX, but in a simpler way than conditional checks in my return statement. I want to show a loader in the case that the child elements aren't ready yet. Here it is:

export class Settings extends React.PureComponent {
  render() {
    const loading = (<div>I'm Loading</div>);
    let content = [];
    let pushMessages = null;
    let emailMessages = null;

    if (this.props.pushPreferences) {
       pushMessages = (<div>Push Content Here</div>);
    }
    if (this.props.emailPreferences) {
      emailMessages = (<div>Email Content Here</div>);
    }

    // Push the components in the order I want
    if (emailMessages) content.push(emailMessages);
    if (pushMessages) content.push(pushMessages);

    return (
      <div>
        {content.length ? content : loading}
      </div>
    )
}

Now, I do realize I could also just put {pushMessages} and {emailMessages} directly in my return() below, but assuming I had even more conditional content, my return() would just look cluttered.

Off course, myDico.Values is List<List<MyType>>.

Use Linq if you want to flattern your lists

var items = myDico.SelectMany (d => d.Value).ToList();

Since you're accessing a web.config you should probably use

using System.Web.Configuration;

WebConfigurationManager.AppSettings["configFile"]

You can use like

1. My table is bellow like..

   <table>
      <thead>
       <tr>
           <th>Details</th>
       </tr>
   </thead>
   <tbody>
       <tr th:each="user: ${staffList}">
           <td><a th:href="@{'/details-view/'+ ${user.userId}}">Details</a></td>
       </tr>
    </tbody>
   </table>
   

2. Here is my controller ..

   @GetMapping(value = "/details-view/{userId}")
   public String details(@PathVariable String userId) { 
   
       Logger.getLogger(getClass().getName()).info("userId-->" + userId);
   
    return "user-details";
   }
   

It's quite simple,

We just have to install the flutter toast package. Refer the following documentation: https://pub.dev/packages/fluttertoast

In the installing tab you will get the dependency which you have to paste it in the pubspec.yaml andthen install.

After this just import the package:

import 'package:fluttertoast/fluttertoast.dart';

Similar to above line.

And then by using FlutterToast class you can use your fluttertoast.

You're Done!!!

I have used a tool in my work its LDRA tool suite

It is used for testing the c/c++ code but it also can check against coding standards such as MISRA etc.

Another way to do it could be by creating an alias. For example in terminal write:

alias printhello='python /home/hello_world.py'

Writing printhello will run hello_world.py, but this is only temporary. To make aliases permanent, you have to add them to bashrc, you can edit it by writing this in the terminal:

gedit ~/.bashrc

1. Open web.config in the directory where the old pages reside

2. Then add code for the old location path and new destination as follows:

   <configuration>
     <location path="services.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/services" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
     <location path="products.htm">
       <system.webServer>
         <httpRedirect enabled="true" destination="http://domain.com/products" httpResponseStatus="Permanent" />
       </system.webServer>
     </location>
   </configuration>
   

You may add as many location paths as necessary.

Yes, but it's clunky as hell, e.g.

<c:choose>
  <c:when test="${condition1}">
    ...
  </c:when>
  <c:when test="${condition2}">
    ...
  </c:when>
  <c:otherwise>
    ...
  </c:otherwise>
</c:choose>

Try

data.items.pop();
data.items.push({id: "7", name: "Matrix", type: "adult"});

var data = {items: [_x000D_
    {id: "1", name: "Snatch", type: "crime"},_x000D_
    {id: "2", name: "Witches of Eastwick", type: "comedy"},_x000D_
    {id: "3", name: "X-Men", type: "action"},_x000D_
    {id: "4", name: "Ordinary People", type: "drama"},_x000D_
    {id: "5", name: "Billy Elliot", type: "drama"},_x000D_
    {id: "6", name: "Toy Story", type: "children"}_x000D_
]};_x000D_
_x000D_
data.items.pop();_x000D_
data.items.push({id: "7", name: "Matrix", type: "adult"});_x000D_
_x000D_
console.log(data);

The best way to add different objects into same container is to use make_shared, vector, and range based loop and you will have a nice, clean and "readable" code!

typedef std::shared_ptr<gate> Ptr   
vector<Ptr> myConatiner; 
auto andGate = std::make_shared<ANDgate>();
myConatiner.push_back(andGate );
auto orGate= std::make_shared<ORgate>();
myConatiner.push_back(orGate);

for (auto& element : myConatiner)
    element->run();

There is also a tool that oracle made called mysqlshow

If you run it with the --k keys $table_name option it will display the keys.

SYNOPSIS
   mysqlshow [options] [db_name [tbl_name [col_name]]]
.......
.......
.......
·   --keys, -k
   Show table indexes.

example:

?-?  mysqlshow -h 127.0.0.1 -u root -p --keys database tokens

In addition to setting the cell as selected, you also need to inform the tableView that the cell is selected. Add a call to -tableView:selectRowAtIndexPath:animated:scrollPosition: to your willDisplayCell: method: and you will be able to deselect it as normal.

- (void)tableView:(UITableView*)tableView 
  willDisplayCell:(UITableViewCell*)cell
forRowAtIndexPath:(NSIndexPath*)indexPath
{ 
    AppDelegate_iPad *appDelegte = (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];

    if ([appDelegte.indexPathDelegate row] == [indexPath row])
    {
        // SELECT CELL
        [cell setSelected:YES]; 
        // TELL TABLEVIEW THAT ROW IS SELECTED
        [tableView selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];   
    } 
}

Be sure to use UITableViewScrollPositionNone to avoid odd scrolling behavior.

Regular expressions with character classes (e.g. [[:digit:]]) are not supported in the default regular expression syntax used by find. You need to specify a different regex type such as posix-extended in order to use them.

Take a look at GNU Find's Regular Expression documentation which shows you all the regex types and what they support.

It is a good practice get the amount you need to store first then initialize the array.

for example, you would ask the user how many data he need to store and then initialize it, or query the component or argument of how many you need to store. if you want a dynamic array you could use ArrayList() and use al.add(); function to keep adding, then you can transfer it to a fixed array.

//Initialize ArrayList and cast string so ArrayList accepts strings (or anything
ArrayList<string> al = new ArrayList(); 
//add a certain amount of data
for(int i=0;i<x;i++)
{
  al.add("data "+i); 
}

//get size of data inside
int size = al.size(); 
//initialize String array with the size you have
String strArray[] = new String[size]; 
//insert data from ArrayList to String array
for(int i=0;i<size;i++)
{
  strArray[i] = al.get(i);
}

doing so is redundant but just to show you the idea, ArrayList can hold objects unlike other primitive data types and are very easy to manipulate, removing anything from the middle is easy as well, completely dynamic.same with List and Stack

Consider building an Add-on that has an actual button and not using the outdated method of linking an image to a script function.

In the script editor, under the Help menu >> Welcome Screen >> link to Google Sheets Add-on - will give you sample code to use.

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

File object docs (for Python 2) here.

#!/bin/bash

variable=`ps -ef | grep "port 10 -" | grep -v "grep port 10 -" | awk '{printf $12}'`
echo $variable

Notice that there's no space after the equal sign.

You can also use $() which allows nesting and is readable.

RasterizeHTML is a very good project, but if you need to access the canvas it wont work on chrome. due to the use of <foreignObject>.

If you need to access the canvas then you can use html2canvas

I am trying to find another project as html2canvas is very slow in performance

You can also have a look at the method findText(const QString & text) from QComboBox; it returns the index of the element which contains the given text, (-1 if not found). The advantage of using this method is that you don't need to set the second parameter when you add an item.

Here is a little example :

/* Create the comboBox */
QComboBox   *_comboBox = new QComboBox;

/* Create the ComboBox elements list (here we use QString) */
QList<QString> stringsList;
stringsList.append("Text1");
stringsList.append("Text3");
stringsList.append("Text4");
stringsList.append("Text2");
stringsList.append("Text5");

/* Populate the comboBox */
_comboBox->addItems(stringsList);

/* Create the label */
QLabel *label = new QLabel;

/* Search for "Text2" text */
int index = _comboBox->findText("Text2");
if( index == -1 )
    label->setText("Text2 not found !");
else
    label->setText(QString("Text2's index is ")
                   .append(QString::number(_comboBox->findText("Text2"))));

/* setup layout */
QVBoxLayout *layout = new QVBoxLayout(this);
layout->addWidget(_comboBox);
layout->addWidget(label);

I use this Bash script to test the internet status every minute on OSX

I find you need the following:

• A top constraint
• A leading constraint (eg left side)
• A trailing constraint (eg right side)
• Set content hugging priority, horizontal to low, so it'll fill the given space if the text is short.
• Set content compression resistance, horizontal to low, so it'll wrap instead of try to become wider.
• Set the number of lines to 0.
• Set the line break mode to word wrap.

Using just scipy, glob and having PIL installed (pip install pillow) you can use scipy's imread method:

from scipy import misc
import glob

for image_path in glob.glob("/home/adam/*.png"):
    image = misc.imread(image_path)
    print image.shape
    print image.dtype

UPDATE

According to the doc, scipy.misc.imread is deprecated starting SciPy 1.0.0, and will be removed in 1.2.0. Consider using imageio.imread instead. See the answer by Charles.

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.

Thanks to @cssko for providing the correct answer, but if you tried it yourself you will realise it does not work. A suggestion has been made by @Matei Radu, but was rejected by @cssko, so the code remains unrunnable (it will throw error 'Cannot read property bind of undefined'). Below is the working correct answer:

class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.addActiveClass = this.addActiveClass.bind(this);
    this.state = {
      active: false,
    };
  }
  addActiveClass() {
    const currentState = this.state.active;
    this.setState({
      active: !currentState
    });
  };

  render() {
    return ( <
      div className = {
        this.state.active ? 'your_className' : null
      }
      onClick = {
        this.addActiveClass
      } >
      <
      p > {
        this.props.text

}

class Test extends React.Component {

      <
      MyComponent text = {

Oh, but that's ugly, non-object-oriented code. The moment you see "if/else" and "typeof", you should be thinking polymorphism. This is the wrong way to go. I think generics are your friend here.

How many types do you plan to deal with?

UPDATE:

If you're just talking about String and int, here's one way you might do it. Start with the interface XmlGenerator (enough with "foo"):

package generics;

public interface XmlGenerator<T>
{
   String getXml(T value);
}

And the concrete implementation XmlGeneratorImpl:

    package generics;

public class XmlGeneratorImpl<T> implements XmlGenerator<T>
{
    private Class<T> valueType;
    private static final int DEFAULT_CAPACITY = 1024;

    public static void main(String [] args)
    {
        Integer x = 42;
        String y = "foobar";

        XmlGenerator<Integer> intXmlGenerator = new XmlGeneratorImpl<Integer>(Integer.class);
        XmlGenerator<String> stringXmlGenerator = new XmlGeneratorImpl<String>(String.class);

        System.out.println("integer: " + intXmlGenerator.getXml(x));
        System.out.println("string : " + stringXmlGenerator.getXml(y));
    }

    public XmlGeneratorImpl(Class<T> clazz)
    {
        this.valueType = clazz;
    }

    public String getXml(T value)
    {
        StringBuilder builder = new StringBuilder(DEFAULT_CAPACITY);

        appendTag(builder);
        builder.append(value);
        appendTag(builder, false);

        return builder.toString();
    }

    private void appendTag(StringBuilder builder) { this.appendTag(builder, false); }

    private void appendTag(StringBuilder builder, boolean isClosing)
    {
        String valueTypeName = valueType.getName();
        builder.append("<").append(valueTypeName);
        if (isClosing)
        {
            builder.append("/");
        }
        builder.append(">");
    }
}

If I run this, I get the following result:

integer: <java.lang.Integer>42<java.lang.Integer>
string : <java.lang.String>foobar<java.lang.String>

I don't know if this is what you had in mind.

For a lambda-avoiding method, first define your own function:

def MyFn(a):
    return a[1]

then:

sorted([('abc', 121),('abc', 231),('abc', 148), ('abc',221)], key=MyFn)

You have to use v-html directive for displaying html content inside a vue component

<div v-html="html content data property"></div>

Centered and middled content ?

Do it this way :

<table style="width:100%">
    <tr>
        <td valign="middle" align="center">Table once ruled centering</td>
    </tr>
</table>

I fiddled it here

Ha, let me guess .. you want DIVs ..

just make your first outter DIV behave like a table-cell then style it with vertical align:middle;

<div>
    <p>I want this paragraph to be at the center, but I can't.</p>
</div>

div {
    width:500px;
    height:100px;
    background-color:aqua;
    text-align:center;
    /*  there it is */
    display:table-cell;
    vertical-align:middle;
}

jsfiddle.net/9Mk64/

$('div').html('');

But why are you clearing, divToUpdate.html(data); will completely replace the old HTML.

There's a few things with your code as it stands:

1. You are using a lot of casting, which is not needed.
2. You are treating your URL as a local file URL, which is not the case.
3. You are never downloading the URL to be used by your image.

The first thing we are going to do is to declare your variable as let, as we are not going to modify it later.

let catPictureURL = URL(string: "http://i.imgur.com/w5rkSIj.jpg")! // We can force unwrap because we are 100% certain the constructor will not return nil in this case.

Then we need to download the contents of that URL. We can do this with the URLSession object. When the completion handler is called, we will have a UIImage downloaded from the web.

// Creating a session object with the default configuration.
// You can read more about it here https://developer.apple.com/reference/foundation/urlsessionconfiguration
let session = URLSession(configuration: .default)

// Define a download task. The download task will download the contents of the URL as a Data object and then you can do what you wish with that data.
let downloadPicTask = session.dataTask(with: catPictureURL) { (data, response, error) in
    // The download has finished.
    if let e = error {
        print("Error downloading cat picture: \(e)")
    } else {
        // No errors found.
        // It would be weird if we didn't have a response, so check for that too.
        if let res = response as? HTTPURLResponse {
            print("Downloaded cat picture with response code \(res.statusCode)")
            if let imageData = data {
                // Finally convert that Data into an image and do what you wish with it.
                let image = UIImage(data: imageData)
                // Do something with your image.
            } else {
                print("Couldn't get image: Image is nil")
            }
        } else {
            print("Couldn't get response code for some reason")
        }
    }
}

Finally you need to call resume on the download task, otherwise your task will never start:

downloadPicTask.resume().

All this code may look a bit intimidating at first, but the URLSession APIs are block based so they can work asynchronously - If you block your UI thread for a few seconds, the OS will kill your app.

Your full code should look like this:

let catPictureURL = URL(string: "http://i.imgur.com/w5rkSIj.jpg")!

// Creating a session object with the default configuration.
// You can read more about it here https://developer.apple.com/reference/foundation/urlsessionconfiguration
let session = URLSession(configuration: .default)

// Define a download task. The download task will download the contents of the URL as a Data object and then you can do what you wish with that data.
let downloadPicTask = session.dataTask(with: catPictureURL) { (data, response, error) in
    // The download has finished.
    if let e = error {
        print("Error downloading cat picture: \(e)")
    } else {
        // No errors found.
        // It would be weird if we didn't have a response, so check for that too.
        if let res = response as? HTTPURLResponse {
            print("Downloaded cat picture with response code \(res.statusCode)")
            if let imageData = data {
                // Finally convert that Data into an image and do what you wish with it.
                let image = UIImage(data: imageData)
                // Do something with your image.
            } else {
                print("Couldn't get image: Image is nil")
            }
        } else {
            print("Couldn't get response code for some reason")
        }
    }
}

downloadPicTask.resume()

The better option would be to just use the resource returned array as an array, meaning :

getResources().getStringArray(R.array.your_array)[position]

This is a shortcut approach of above mentioned approaches but does the work in the fashion you want. Otherwise android doesnt provides direct XML indexing for xml based arrays.

In your question, you asked for the fastest way to do it. As has been demonstrated repeatedly, particularly with Python, intuition is not a reliable guide: you need to measure.

Here's a simple test of several different implementations:

import sys
from collections import Counter, defaultdict
from itertools import groupby
from operator import itemgetter
from timeit import timeit

L = [1,2,45,55,5,4,4,4,4,4,4,5456,56,6,7,67]

def max_occurrences_1a(seq=L):
    "dict iteritems"
    c = dict()
    for item in seq:
        c[item] = c.get(item, 0) + 1
    return max(c.iteritems(), key=itemgetter(1))

def max_occurrences_1b(seq=L):
    "dict items"
    c = dict()
    for item in seq:
        c[item] = c.get(item, 0) + 1
    return max(c.items(), key=itemgetter(1))

def max_occurrences_2(seq=L):
    "defaultdict iteritems"
    c = defaultdict(int)
    for item in seq:
        c[item] += 1
    return max(c.iteritems(), key=itemgetter(1))

def max_occurrences_3a(seq=L):
    "sort groupby generator expression"
    return max(((k, sum(1 for i in g)) for k, g in groupby(sorted(seq))), key=itemgetter(1))

def max_occurrences_3b(seq=L):
    "sort groupby list comprehension"
    return max([(k, sum(1 for i in g)) for k, g in groupby(sorted(seq))], key=itemgetter(1))

def max_occurrences_4(seq=L):
    "counter"
    return Counter(L).most_common(1)[0]

versions = [max_occurrences_1a, max_occurrences_1b, max_occurrences_2, max_occurrences_3a, max_occurrences_3b, max_occurrences_4]

print sys.version, "\n"

for vers in versions:
    print vers.__doc__, vers(), timeit(vers, number=20000)

The results on my machine:

2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] 

dict iteritems (4, 6) 0.202214956284
dict items (4, 6) 0.208412885666
defaultdict iteritems (4, 6) 0.221301078796
sort groupby generator expression (4, 6) 0.383440971375
sort groupby list comprehension (4, 6) 0.402786016464
counter (4, 6) 0.564319133759

So it appears that the Counter solution is not the fastest. And, in this case at least, groupby is faster. defaultdict is good but you pay a little bit for its convenience; it's slightly faster to use a regular dict with a get.

What happens if the list is much bigger? Adding L *= 10000 to the test above and reducing the repeat count to 200:

dict iteritems (4, 60000) 10.3451900482
dict items (4, 60000) 10.2988479137
defaultdict iteritems (4, 60000) 5.52838587761
sort groupby generator expression (4, 60000) 11.9538850784
sort groupby list comprehension (4, 60000) 12.1327362061
counter (4, 60000) 14.7495789528

Now defaultdict is the clear winner. So perhaps the cost of the 'get' method and the loss of the inplace add adds up (an examination of the generated code is left as an exercise).

But with the modified test data, the number of unique item values did not change so presumably dict and defaultdict have an advantage there over the other implementations. So what happens if we use the bigger list but substantially increase the number of unique items? Replacing the initialization of L with:

LL = [1,2,45,55,5,4,4,4,4,4,4,5456,56,6,7,67]
L = []
for i in xrange(1,10001):
    L.extend(l * i for l in LL)

dict iteritems (2520, 13) 17.9935798645
dict items (2520, 13) 21.8974409103
defaultdict iteritems (2520, 13) 16.8289561272
sort groupby generator expression (2520, 13) 33.853593111
sort groupby list comprehension (2520, 13) 36.1303369999
counter (2520, 13) 22.626899004

So now Counter is clearly faster than the groupby solutions but still slower than the iteritems versions of dict and defaultdict.

The point of these examples isn't to produce an optimal solution. The point is that there often isn't one optimal general solution. Plus there are other performance criteria. The memory requirements will differ substantially among the solutions and, as the size of the input goes up, memory requirements may become the overriding factor in algorithm selection.

Bottom line: it all depends and you need to measure.

Use String.trim() method to get rid of whitespaces (spaces, new lines etc.) from the beginning and end of the string.

String trimmedString = myString.trim();

You can use the DATE_ADD() function:

... WHERE DATE(DATE_ADD(eventdate, INTERVAL -1 DAY)) = CURRENT_DATE

It can also be used in the SELECT statement:

SELECT DATE_ADD('2010-05-11', INTERVAL 1 DAY) AS Tomorrow;
+------------+
| Tomorrow   |
+------------+
| 2010-05-12 |
+------------+
1 row in set (0.00 sec)

For the case where n <= 0, T(n) = O(1). Therefore, the time complexity will depend on when n >= 0.

We will consider the case n >= 0 in the part below.

1.

T(n) = a + T(n - 1)

where a is some constant.

By induction:

T(n) = n * a + T(0) = n * a + b = O(n)

where a, b are some constant.

2.

T(n) = a + T(n - 5)

where a is some constant

By induction:

T(n) = ceil(n / 5) * a + T(k) = ceil(n / 5) * a + b = O(n)

where a, b are some constant and k <= 0

3.

T(n) = a + T(n / 5)

where a is some constant

By induction:

T(n) = a * log5(n) + T(0) = a * log5(n) + b = O(log n)

where a, b are some constant

4.

T(n) = a + 2 * T(n - 1)

where a is some constant

By induction:

T(n) = a + 2a + 4a + ... + 2^(n-1) * a + T(0) * 2^n 
     = a * 2^n - a + b * 2^n
     = (a + b) * 2^n - a
     = O(2 ^ n)

where a, b are some constant.

5.

T(n) = n / 2 + T(n - 5)

where n is some constant

Rewrite n = 5q + r where q and r are integer and r = 0, 1, 2, 3, 4

T(5q + r) = (5q + r) / 2 + T(5 * (q - 1) + r)

We have q = (n - r) / 5, and since r < 5, we can consider it a constant, so q = O(n)

By induction:

T(n) = T(5q + r)
     = (5q + r) / 2 + (5 * (q - 1) + r) / 2 + ... + r / 2 +  T(r)
     = 5 / 2 * (q + (q - 1) + ... + 1) +  1 / 2 * (q + 1) * r + T(r)
     = 5 / 4 * (q + 1) * q + 1 / 2 * (q + 1) * r + T(r)
     = 5 / 4 * q^2 + 5 / 4 * q + 1 / 2 * q * r + 1 / 2 * r + T(r)

Since r < 4, we can find some constant b so that b >= T(r)

T(n) = T(5q + r)
     = 5 / 2 * q^2 + (5 / 4 + 1 / 2 * r) * q + 1 / 2 * r + b
     = 5 / 2 * O(n ^ 2) + (5 / 4 + 1 / 2 * r) * O(n) + 1 / 2 * r + b
     = O(n ^ 2)

For the fun of it, here's some code that should work in SQL Server, Oracle, or MySQL:

SELECT current_timestamp - CAST(d1.digit + d2.digit + d3.digit as int)
FROM 
(
    SELECT digit
    FROM
    (
        select '1' as digit
        union select '2'
        union select '3'
        union select '4'
        union select '5'
        union select '6'
        union select '7'
        union select '8'
        union select '9'
        union select '0'
    ) digits
) d1
CROSS JOIN
(
    SELECT digit
    FROM
    (
        select '1' as digit
        union select '2'
        union select '3'
        union select '4'
        union select '5'
        union select '6'
        union select '7'
        union select '8'
        union select '9'
        union select '0'
    ) digits
) d2
CROSS JOIN
(
    SELECT digit
    FROM
    (
        select '1' as digit
        union select '2'
        union select '3'
        union select '4'
        union select '5'
        union select '6'
        union select '7'
        union select '8'
        union select '9'
        union select '0'
    ) digits
) d3
WHERE CAST(d1.digit + d2.digit + d3.digit as int) < 365
ORDER BY d1.digit, d2.digit, d3.digit -- order not really needed here

Bonus points if you can give me a cross-platform syntax to re-use the digits table.

Update 2019

In Bootstrap 4, flexbox can be used to get a full height layout that fills the remaining space.

First of all, the container (parent) needs to be full height:

Option 1_ Add a class for min-height: 100%;. Remember that min-height will only work if the parent has a defined height:

html, body {
  height: 100%;
}

.min-100 {
    min-height: 100%;
}

https://codeply.com/go/dTaVyMah1U

Option 2_ Use vh units:

.vh-100 {
    min-height: 100vh;
}

https://codeply.com/go/kMahVdZyGj

Also of Bootstrap 4.1, the vh-100 and min-vh-100 classes are included in Bootstrap so there is no need to for the extra CSS

Then, use flexbox direction column d-flex flex-column on the container, and flex-grow-1 on any child divs (ie: row) that you want to fill the remaining height.

Also see:
Bootstrap 4 Navbar and content fill height flexbox

Above answers are helpful, I'd just like to add an example that I think is demonstrating clearly what happens when we pass parameter without the ref keyword, even when that parameter is a reference type:

MyClass c = new MyClass(); c.MyProperty = "foo";

CNull(c); // only a copy of the reference is sent 
Console.WriteLine(c.MyProperty); // still foo, we only made the copy null
CPropertyChange(c); 
Console.WriteLine(c.MyProperty); // bar


private void CNull(MyClass c2)
        {          
            c2 = null;
        }
private void CPropertyChange(MyClass c2) 
        {
            c2.MyProperty = "bar"; // c2 is a copy, but it refers to the same object that c does (on heap) and modified property would appear on c.MyProperty as well.
        }

Tried and tested approach.

public static ArrayList<String> listToArrayList(List<Object> myList) {
        ArrayList<String> arl = new ArrayList<String>();
        for (Object object : myList) {
            arl.add((String) object);
        }
        return arl;

    }

Just an update for Android Studio 1.5.1 on Windows:

Go to File -> Settings -> follow picture

You can use LENGTH() for CHAR / VARCHAR2 and DBMS_LOB.GETLENGTH() for CLOB. Both functions will count actual characters (not bytes).

See the linked documentation if you do need bytes.

The solution didn't work for me, I had to adapt it:

protected void Page_Load(object sender, EventArgs e)
{
    string script;
    if (IsPostBack)
    {
        script = "var isPostBack = true;";
    }
    else
    {
        script = "var isPostBack = false;";
    }
    Page.ClientScript.RegisterStartupScript(GetType(), "IsPostBack", script, true);
}

Hope this helps.

I'm not sure of all the details, but my understanding is that OLE DB and ODBC are two APIs that are available for connecting to various types of databases without having to deal with all the implementation specific details of each. According to the Wikipedia article on OLE DB, OLE DB is Microsoft's successor to ODBC, and provides some features that you might not be able to do with ODBC such as accessing spreadsheets as database sources.

I've never had this problem, but I create a ~/.crontab file and edit that (which allows me to back it up, Time Machine or otherwise), then run

crontab ~/.crontab

Has worked for me for 20+ years across many flavors of unix.

List is an interface and ArrayList is an implementation of the List interface. The ArrayList class has only a few methods(i.e clone(), trimToSize(), removeRange() and ensureCapacity()) in addition to the methods available in the List interface. There is not much difference in this.

   1. List<String> l = new ArrayList<>();
   2. ArrayList<String> l = new ArrayList<>();

If you use the first, you will be able to call the methods available in the List interface and you cannot make calls to the new methods available in the ArrayList class. Where as, you are free to use all the methods available in the ArrayList if you use the second one.

I would say the first approach is a better one because, when you are developing java applications, when you are supposed to pass the collection framework objects as arguments to the methods, then it is better to go with first approach.

List<String> l = new ArrayList<>();
doSomething(l);

In future due to performance constraints, if you are changing the implementation to use LinkedList or someother classes which implements List interface, instead of ArrayList, you need to change at one point only(the instantiation part).

List<String> l = new LinkedList<>();

Else you will be supposed to change at all the places, wherever, you have used the specific class implementation as method arguments.

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

tl;dr

SELECT character_set_name 
FROM information_schema.character_sets 
;

Standard way: information_schema

From the SQL-standard schema information_schema present in every database/catalog, use the defined view named character_sets. This approach should be portable across all standard database systems.

SELECT *

Despite the name being plural, it shows only a single row, reporting on the current database/catalog.

The third column is character_set_name:

Name of the character set, currently implemented as showing the name of the database encoding

You can try out this phone validator package. Laravel Phone

Update

I recently discovered another package Lavarel Phone Validator (stuyam/laravel-phone-validator), that uses the free Twilio phone lookup service

Personally, I would say Web World's answer is the best today, given HTML standards. If you need to support IE < 10, you will need to use some form of ActiveX. I would avoid the recommendations that involve coding against Scripting.FileSystemObject, or instantiating ActiveX directly.

In this case, I have had success using 3rd party JS libraries such as plupload which can be configured to use HTML5 apis or Flash/Silverlight controls to backfill browsers that don't support those. Plupload has a client side API for checking file size that works in IE < 10.

Additionally,

ggplot(dat, aes(x,y)) +
geom_point() +
scale_x_continuous(breaks = seq(min(dat$x), max(dat$x), by = 0.05))

Works for binned or discrete scaled x-axis data (I.e., rounding not necessary).

Sharing my notes which I usually maintain while reading from Internet, I hope it may be helpful to someone

Candidate Key or available keys

Candidate keys are those keys which is candidate for primary key of a table. In simple words we can understand that such type of keys which full fill all the requirements of primary key which is not null and have unique records is a candidate for primary key. So thus type of key is known as candidate key. Every table must have at least one candidate key but at the same time can have several.

Primary Key

Such type of candidate key which is chosen as a primary key for table is known as primary key. Primary keys are used to identify tables. There is only one primary key per table. In SQL Server when we create primary key to any table then a clustered index is automatically created to that column.

Foreign Key

Foreign key are those keys which is used to define relationship between two tables. When we want to implement relationship between two tables then we use concept of foreign key. It is also known as referential integrity. We can create more than one foreign key per table. Foreign key is generally a primary key from one table that appears as a field in another where the first table has a relationship to the second. In other words, if we had a table A with a primary key X that linked to a table B where X was a field in B, then X would be a foreign key in B.

Alternate Key or Secondary

If any table have more than one candidate key, then after choosing primary key from those candidate key, rest of candidate keys are known as an alternate key of that table. Like here we can take a very simple example to understand the concept of alternate key. Suppose we have a table named Employee which has two columns EmpID and EmpMail, both have not null attributes and unique value. So both columns are treated as candidate key. Now we make EmpID as a primary key to that table then EmpMail is known as alternate key.

Composite Key

When we create keys on more than one column then that key is known as composite key. Like here we can take an example to understand this feature. I have a table Student which has two columns Sid and SrefNo and we make primary key on these two column. Then this key is known as composite key.

Natural keys

A natural key is one or more existing data attributes that are unique to the business concept. For the Customer table there was two candidate keys, in this case CustomerNumber and SocialSecurityNumber. Link http://www.agiledata.org/essays/keys.html

Surrogate key

Introduce a new column, called a surrogate key, which is a key that has no business meaning. An example of which is the AddressID column of the Address table in Figure 1. Addresses don't have an "easy" natural key because you would need to use all of the columns of the Address table to form a key for itself (you might be able to get away with just the combination of Street and ZipCode depending on your problem domain), therefore introducing a surrogate key is a much better option in this case. Link http://www.agiledata.org/essays/keys.html

Unique key

A unique key is a superkey--that is, in the relational model of database organization, a set of attributes of a relation variable for which it holds that in all relations assigned to that variable, there are no two distinct tuples (rows) that have the same values for the attributes in this set

Aggregate or Compound keys

When more than one column is combined to form a unique key, their combined value is used to access each row and maintain uniqueness. These keys are referred to as aggregate or compound keys. Values are not combined, they are compared using their data types.

Simple key

Simple key made from only one attribute.

Super key

A superkey is defined in the relational model as a set of attributes of a relation variable (relvar) for which it holds that in all relations assigned to that variable there are no two distinct tuples (rows) that have the same values for the attributes in this set. Equivalently a super key can also be defined as a set of attributes of a relvar upon which all attributes of the relvar are functionally dependent.

Partial Key or Discriminator key

It is a set of attributes that can uniquely identify weak entities and that are related to same owner entity. It is sometime called as Discriminator.

I have used enum FragmentTags to define all my fragment classes.

TAG_FOR_FRAGMENT_A(A.class),
TAG_FOR_FRAGMENT_B(B.class),
TAG_FOR_FRAGMENT_C(C.class)

pass FragmentTags.TAG_FOR_FRAGMENT_A.name() as fragment tag.

and now on

@Override
public void onBackPressed(){
   FragmentManager fragmentManager = getFragmentManager();
   Fragment current
   = fragmentManager.findFragmentById(R.id.fragment_container);
    FragmentTags fragmentTag = FragmentTags.valueOf(current.getTag());

  switch(fragmentTag){
    case TAG_FOR_FRAGMENT_A:
        finish();
        break;
   case TAG_FOR_FRAGMENT_B:
        fragmentManager.popBackStack();
        break;
   case default: 
   break;
}

varchar [ ( n | max ) ] Variable-length, non-Unicode character data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of data entered + 2 bytes. The data entered can be 0 characters in length. The ISO synonyms for varchar are char varying or character varying.

1 character = 1 byte. And don't forget 2 bytes for the termination. So, 2^31-3 characters.

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

Refer this link for more info

CODEPEN

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

Here is how I did it.

There are some things to change in your code:

1. Change the name of your output to 'output.mp4' (change to .mp4)
2. I had the the same issues that people have in the comments, so I changed the fourcc to 0x7634706d: out = cv2.VideoWriter('output.mp4',0x7634706d , 20.0, (640,480))

The dropdown list appearing like that depends on what your browser is, as it is not possible to style this away for some. It looks like yours is IE9, but would look quite different in Chrome.

You could look to use something like this:

http://silviomoreto.github.io/bootstrap-select/

Which will make your selectboxes more consistent cross browser.

I dont have a direct answer, but you might want to look into these things:

• Recoil project - https://github.com/recoilphp/recoil
• php's LibEvent extension? http://www.php.net/manual/en/book.libevent.php
• process forking http://www.php.net/manual/en/function.pcntl-fork.php
• message brokers, i.e. you could start workers to make the HTTP calls and once that job is done, insert a new job describing the work that needs to be done in order to process the cached HTTP response body.

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

If you just need to convert an expected 8-bit value from a signed int to an unsigned value, you can use simple bit shifting:

int signed = -119;  // 11111111 11111111 11111111 10001001

/**
 * Use unsigned right shift operator to drop unset bits in positions 8-31
 */
int psuedoUnsigned = (signed << 24) >>> 24;  // 00000000 00000000 00000000 10001001 -> 137 base 10

/** 
 * Convert back to signed by using the sign-extension properties of the right shift operator
 */
int backToSigned = (psuedoUnsigned << 24) >> 24; // back to original bit pattern

http://docs.oracle.com/javase/tutorial/java/nutsandbolts/op3.html

If using something other than int as the base type, you'll obviously need to adjust the shift amount: http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html

Also, bear in mind that you can't use byte type, doing so will result in a signed value as mentioned by other answerers. The smallest primitive type you could use to represent an 8-bit unsigned value would be a short.

Use System.IO.File.Delete like so:

System.IO.File.Delete(@"C:\test.txt")

From the documentation:

If the file to be deleted does not exist, no exception is thrown.

I'm thinking no. Bookmarks/favorites should be under the control of the user, imagine if any site you visited could insert itself into your bookmarks with just some javascript.

I'm surprised no one mentioned the possibility to use an API to do the work.

Granted, if you want to stay secure, converting HTML to PDF directly from within the browser using javascript is not a good idea.

But here's what you can do:

When your user hit the "Print" (for example) button, you:

1. Send a request to your server at a specific endpoint with details about what to convert (URL of the page for instance).
2. This endpoint will then send the data to convert to an API, and will receive the PDF in response
3. which it will return to your user.

For a user point of view, they will receive a PDF by clicking on a button.

There are many available API that does the job, some better than others (that's not why I'm here) and a Google search will give you a lot of answers.

Depending on what is written your backend, you might be interested in PDFShift (Truth: I work there).

They offer ready to work packages for PHP, Python and Node.js. All you have to do is install the package, create an account, indicate your API key and you are all set!

The advantage of the API is that they work well in all languages. All you have to do is a request (generally POST) containing the data you want to be converted and get a PDF back. And depending on your usage, it's generally free, except if you are a heavy user.

Rather than going the harder route of downloading specific packages. I prefer to go the faster route of using Conda. pip has its issues.

That depends. If that definition is global (outside any function) then num will be initialized to zero. If it's local (inside a function) then its value is indeterminate. In theory, even attempting to read the value has undefined behavior -- C allows for the possibility of bits that don't contribute to the value, but have to be set in specific ways for you to even get defined results from reading the variable.

A solution faster than using set() that works on sequences (not iterables) is to simply count the first element. This assumes the list is non-empty (but that's trivial to check, and decide yourself what the outcome should be on an empty list)

x.count(x[0]) == len(x)

some simple benchmarks:

>>> timeit.timeit('len(set(s1))<=1', 's1=[1]*5000', number=10000)
1.4383411407470703
>>> timeit.timeit('len(set(s1))<=1', 's1=[1]*4999+[2]', number=10000)
1.4765670299530029
>>> timeit.timeit('s1.count(s1[0])==len(s1)', 's1=[1]*5000', number=10000)
0.26274609565734863
>>> timeit.timeit('s1.count(s1[0])==len(s1)', 's1=[1]*4999+[2]', number=10000)
0.25654196739196777

Use try-catch to avoid it:

var result = null;
try {
  // if jQuery
  result = $.parseJSON(JSONstring);
  // if plain js
  result = JSON.parse(JSONstring);
}
catch(e) {
  // forget about it :)
}

Maybe not as elegant as some previous answers, but if you want to achieve switch cases with few large ranges, just combine ranges to a single case beforehand:

// make a switch variable so as not to change the original value
int switchVariable = variable;

//combine range 1-100 to one single case in switch
if(1 <= variable && variable <=100)
    switchVariable = 1;
switch (switchVariable) 
{ 
    case 0:
        break; 
    case 1:
        // range 1-100
        doSomething(); 
        break;
    case 101: 
        doSomethingElse(); 
        break;
    etc.
} 

For Windows Users :

If this issue occurs on your self hosted server (eg: your custom CDN) and the browser (Chrome) says something like ... ('text/plain') is not executable ... when trying to load your javascript file ...

Here is what you need to do :

1. Open the Registry Editor i.e Win + R > regedit
2. Head over to HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.js
3. Check to if the Content Type is application/javascript or not
4. If not, then change it to application/javascript and try again

The correct way from hibernate doc:

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

        tx = s.beginTransaction();        

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

        tx.commit();

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

HibernateUtil code (can find at Google):

            public class HibernateUtil {

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

                static {

                    try {

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

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

                public static SessionFactory getSessionFactory() {
                    return tmrSessionFactory;
                }

                /* getters and setters here */


            }

Use the format() function with a '02x' format.

>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'

The 02 part tells format() to use at least 2 digits and to use zeros to pad it to length, x means lower-case hexadecimal.

The Format Specification Mini Language also gives you X for uppercase hex output, and you can prefix the field width with # to include a 0x or 0X prefix (depending on wether you used x or X as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:

>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'

If you have a "Win32 project" + defined a WinMain and your SubSystem linker setting is set to WINDOWS you can still get this linker error in case somebody set the "Additional Options" in the linker settings to "/SUBSYSTEM:CONSOLE" (looks like this additional setting is preferred over the actual SubSystem setting.

ref: In javascript, how do you search an array for a substring match

The solution given here is generic unlike the solution 4556343#4556343, which requires a previous parse to identify a string with which to join(), that is not a component of any of the array strings.
Also, in that code /!id-[^!]*/ is more correctly, /![^!]*id-[^!]*/ to suit the question parameters:

1. "search an array ..." (of strings or numbers and not functions, arrays, objects, etc.)
2. "for only part of the string to match " (match can be anywhere)
3. "return the ... matched ... element" (singular, not ALL, as in "... the ... elementS")
4. "with the full string" (include the quotes)

... NetScape / FireFox solutions (see below for a JSON solution):

javascript:         /* "one-liner" statement solution */
   alert(
      ["x'!x'\"id-2",'\' "id-1 "',   "item","thing","id-3-text","class" ] .
         toSource() . match( new RegExp( 
            '[^\\\\]("([^"]|\\\\")*' + 'id-' + '([^"]|\\\\")*[^\\\\]")' ) ) [1]
   );

or

javascript:
   ID = 'id-' ;
   QS = '([^"]|\\\\")*' ;           /* only strings with escaped double quotes */
   RE = '[^\\\\]("' +QS+ ID +QS+ '[^\\\\]")' ;/* escaper of escaper of escaper */
   RE = new RegExp( RE ) ;
   RA = ["x'!x'\"id-2",'\' "id-1 "',   "item","thing","id-3-text","class" ] ;
   alert(RA.toSource().match(RE)[1]) ;

displays "x'!x'\"id-2".
Perhaps raiding the array to find ALL matches is 'cleaner'.

/* literally (? backslash star escape quotes it!) not true, it has this one v  */
javascript:                            /* purely functional - it has no ... =! */
   RA = ["x'!x'\"id-2",'\' "id-1 "',   "item","thing","id-3-text","class" ] ;
   function findInRA(ra,id){
      ra.unshift(void 0) ;                                     /* cheat the [" */
      return ra . toSource() . match( new RegExp(
             '[^\\\\]"' + '([^"]|\\\\")*' + id + '([^"]|\\\\")*' + '[^\\\\]"' ,
             'g' ) ) ;
   }
   alert( findInRA( RA, 'id-' ) . join('\n\n') ) ;

displays:

     "x'!x'\"id-2"

     "' \"id-1 \""

     "id-3-text"

Using, JSON.stringify():

javascript:                             /* needs prefix cleaning */
   RA = ["x'!x'\"id-2",'\' "id-1 "',   "item","thing","id-3-text","class" ] ;
   function findInRA(ra,id){
      return JSON.stringify( ra ) . match( new RegExp(
             '[^\\\\]"([^"]|\\\\")*' + id + '([^"]|\\\\")*[^\\\\]"' ,
             'g' ) ) ;
   }
   alert( findInRA( RA, 'id-' ) . join('\n\n') ) ;

displays:

    ["x'!x'\"id-2"

    ,"' \"id-1 \""

    ,"id-3-text"

wrinkles:

• The "unescaped" global RegExp is /[^\]"([^"]|\")*id-([^"]|\")*[^\]"/g with the \ to be found literally. In order for ([^"]|\")* to match strings with all "'s escaped as \", the \ itself must be escaped as ([^"]|\\")*. When this is referenced as a string to be concatenated with id-, each \ must again be escaped, hence ([^"]|\\\\")*!
• A search ID that has a \, *, ", ..., must also be escaped via .toSource() or JSON or ... .
• null search results should return '' (or "" as in an EMPTY string which contains NO "!) or [] (for all search).
• If the search results are to be incorporated into the program code for further processing, then eval() is necessary, like eval('['+findInRA(RA,ID).join(',')+']').

--------------------------------------------------------------------------------

Digression:
Raids and escapes? Is this code conflicted?
The semiotics, syntax and semantics of /* it has no ... =! */ emphatically elucidates the escaping of quoted literals conflict.

Does "no =" mean:

• "no '=' sign" as in javascript:alert('\x3D') (Not! Run it and see that there is!),
• "no javascript statement with the assignment operator",
• "no equal" as in "nothing identical in any other code" (previous code solutions demonstrate there are functional equivalents),
• ...

Quoting on another level can also be done with the immediate mode javascript protocol URI's below. (// commentaries end on a new line (aka nl, ctrl-J, LineFeed, ASCII decimal 10, octal 12, hex A) which requires quoting since inserting a nl, by pressing the Return key, invokes the URI.)

javascript:/* a comment */  alert('visible')                                ;
javascript:// a comment ;   alert(  'not'  ) this is all comment             %0A;
javascript:// a comment %0A alert('visible but  %\0A  is wrong ')   // X     %0A
javascript:// a comment %0A alert('visible but %'+'0A is a pain to type')   ;

Note: Cut and paste any of the javascript: lines as an immediate mode URI (at least, at most?, in FireFox) to use first javascript: as a URI scheme or protocol and the rest as JS labels.

For me I did enter a invalid url like : orcl only instead of jdbc:oracle:thin:@//localhost:1521/orcl

I store encoded HTML in the database.

Imho you should not store your data html-encoded in the database. Just store in plain text (not encoded) and just display your data like this and your html will be automatically encoded:

<div class='content'>
    @Model.Content
</div>

Either you can use RAW SQL:

INSERT INTO DEST_TABLE (Field1, Field2) 
SELECT Source_Field1, Source_Field2 
FROM SOURCE_TABLE

Or use the wizard:

1. Right Click on the Database -> Tasks -> Export Data
2. Select the source/target Database
3. Select source/target table and fields
4. Copy the data

Then execute:

TRUNCATE TABLE SOURCE_TABLE

DataRow rw = table.AsEnumerable().FirstOrDefault(tt => tt.Field<string>("Author") == "Name");
if (rw != null)
{
// row exists
}

add to your using clause :

using System.Linq;

and add :

System.Data.DataSetExtensions

to references.

Try using Response.SetCookie(), because Response.Cookies.Add() can cause multiple cookies to be added, whereas SetCookie will update an existing cookie.

This has been a recurring question for many years. (The numbers keep changing, but the concept is the same: how do I view or edit files that are larger than memory?)

Obviously more or less are good approaches to merely reading the files --- less even offers vi like keybindings for scrolling and searching.

A Freshmeat search on "large files" suggests that two editors would be particularly suited to your needs.

One would be: lfhex ... a large file hex editor (which depends on Qt). That one, obviously, entails using a GUI.

Another would seem to be suited to console use: hed ... and it claims to have a vim-like interface (including an ex mode?).

I'm sure I've seen other editors for Linux/UNIX that were able to page through files without loading their entirety into memory. However, I don't recall any of their names. I'm making this response a "wiki" entry to encourage others to add their links to such editors. (Yes, I am familiar with ways to work around the issue using split and cat; but I'm thinking of editors, especially console/curses editors which can dispense with that and save us the time/latencies and disk space overhead that such approaches entail).

EDIT Until such time as StackOverflow allows us to version our answers, this is an answer that works for Android 3 and below. Please don't downvote it because it's not working for you now, because it definitely works with older Android versions.

You should only need to add one line to your onCreateDialog() method:

@Override
protected Dialog onCreateDialog(int id) {
    //all other dialog stuff (which dialog to display)

    //this line is what you need:
    dialog.getWindow().setFlags(LayoutParams.FLAG_FULLSCREEN, LayoutParams.FLAG_FULLSCREEN);

    return dialog;
}

How about the following one? Should allow you to use either raw_input or input in both Python2 and Python3 with the semantics of Python2's raw_input (aka the semantics of Python3's input)

# raw_input isn't defined in Python3.x, whereas input wasn't behaving like raw_input in Python 2.x
# this should make both input and raw_input work in Python 2.x/3.x like the raw_input from Python 2.x 
try: input = raw_input
except NameError: raw_input = input

From Git help:

 Changes to be committed:
      (use "git restore --staged <file>..." to unstage)

    Changes not staged for commit:
      (use "git add <file>..." to update what will be committed)
      (use "git restore <file>..." to discard changes in working directory)

For those of you running into the DirectoryNotFoundException, add this check:

if (Directory.Exists(path)) Directory.Delete(path, true);

This looks like a case of inlining gone bad. On an x86 core, the jitter has the ebx, edx, esi and edi register available for general purpose storage of local variables. The ecx register becomes available in a static method, it doesn't have to store this. The eax register often is needed for calculations. But these are 32-bit registers, for variables of type long it must use a pair of registers. Which are edx:eax for calculations and edi:ebx for storage.

Which is what stands out in the disassembly for the slow version, neither edi nor ebx are used.

When the jitter can't find enough registers to store local variables then it must generate code to load and store them from the stack frame. That slows down code, it prevents a processor optimization named "register renaming", an internal processor core optimization trick that uses multiple copies of a register and allows super-scalar execution. Which permits several instructions to run concurrently, even when they use the same register. Not having enough registers is a common problem on x86 cores, addressed in x64 which has 8 extra registers (r9 through r15).

The jitter will do its best to apply another code generation optimization, it will try to inline your Fibo() method. In other words, not make a call to the method but generate the code for the method inline in the Main() method. Pretty important optimization that, for one, makes properties of a C# class for free, giving them the perf of a field. It avoids the overhead of making the method call and setting up its stack frame, saves a couple of nanoseconds.

There are several rules that determine exactly when a method can be inlined. They are not exactly documented but have been mentioned in blog posts. One rule is that it won't happen when the method body is too large. That defeats the gain from inlining, it generates too much code that doesn't fit as well in the L1 instruction cache. Another hard rule that applies here is that a method won't be inlined when it contains a try/catch statement. The background behind that one is an implementation detail of exceptions, they piggy-back onto Windows' built-in support for SEH (Structure Exception Handling) which is stack-frame based.

One behavior of the register allocation algorithm in the jitter can be inferred from playing with this code. It appears to be aware of when the jitter is trying to inline a method. One rule it appears to use that only the edx:eax register pair can be used for inlined code that has local variables of type long. But not edi:ebx. No doubt because that would be too detrimental to the code generation for the calling method, both edi and ebx are important storage registers.

So you get the fast version because the jitter knows up front that the method body contains try/catch statements. It knows it can never be inlined so readily uses edi:ebx for storage for the long variable. You got the slow version because the jitter didn't know up front that inlining wouldn't work. It only found out after generating the code for the method body.

The flaw then is that it didn't go back and re-generate the code for the method. Which is understandable, given the time constraints it has to operate in.

This slow-down doesn't occur on x64 because for one it has 8 more registers. For another because it can store a long in just one register (like rax). And the slow-down doesn't occur when you use int instead of long because the jitter has a lot more flexibility in picking registers.

It is originally an answer in the comments from @Mark Rajcok, But I want to place it here as a tested and worked as a solution using ChangeDetectorRef , I see a good point here:

Another alternative is to inject ChangeDetectorRef and call cdRef.detectChanges() instead of zone.run(). This could be more efficient, since it will not run change detection over the entire component tree like zone.run() does. – Mark Rajcok

So code must be like:

import {Component, OnInit, ChangeDetectorRef} from 'angular2/core';

export class RecentDetectionComponent implements OnInit {

    recentDetections: Array<RecentDetection>;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        timer.subscribe(() => this.getRecentDetections());
    }
} 

Edit: Using .detectChanges() inside subscibe could lead to issue Attempt to use a destroyed view: detectChanges

To solve it you need to unsubscribe before you destroy the component, so the full code will be like:

import {Component, OnInit, ChangeDetectorRef, OnDestroy} from 'angular2/core';

export class RecentDetectionComponent implements OnInit, OnDestroy {

    recentDetections: Array<RecentDetection>;
    private timerObserver: Subscription;

    constructor(private cdRef: ChangeDetectorRef, // <== added
                private recentDetectionService: RecentDetectionService) {
        this.recentDetections = new Array<RecentDetection>();
    }

    getRecentDetections(): void {
        this.recentDetectionService.getJsonFromApi()
            .subscribe(recent => {
                this.recentDetections = recent;
                console.log(this.recentDetections[0].macAddress);
                this.cdRef.detectChanges(); // <== added
            });
    }

    ngOnInit() {
        this.getRecentDetections();
        let timer = Observable.timer(2000, 5000);
        this.timerObserver = timer.subscribe(() => this.getRecentDetections());
    }

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

}

If you have the table definition to have an IDENTITY column e.g. IDENTITY(1,1) then don't include MyId in your INSERT INTO statement. The point of IDENTITY is it gives it the next unused value as the primary key value.

insert into MYDB.dbo.MainTable (MyFirstName, MyLastName, MyAddress, MyPort)
values(@myFirstName, @myLastName, @myAddress, @myPort)

There is then no need to pass the @MyId parameter into your stored procedure either. So change it to:

CREATE PROCEDURE [dbo].[sp_Test]
@myFirstName nvarchar(50)
,@myLastName nvarchar(50)
,@myAddress nvarchar(MAX)
,@myPort int

AS 

If you want to know what the ID of the newly inserted record is add

SELECT @@IDENTITY

to the end of your procedure. e.g. http://msdn.microsoft.com/en-us/library/ms187342.aspx

You will then be able to pick this up in which ever way you are calling it be it SQL or .NET.

P.s. a better way to show you table definision would have been to script the table and paste the text into your stackoverflow browser window because your screen shot is missing the column properties part where IDENTITY is set via the GUI. To do that right click the table 'Script Table as' --> 'CREATE to' --> Clipboard. You can also do File or New Query Editor Window (all self explanitory) experient and see what you get.

Javascript String objects have a split function, doesn't really need to be jQuery specific

 var str = "nice.test"
 var strs = str.split(".")

strs would be

 ["nice", "test"]

I'd be tempted to use JSON in your example though. The php could return the JSON which could easily be parsed

 success: function(data) {
   var items = JSON.parse(data)
 }

AFAIS, no one mentions of atomic reference.

Integer

public void swap(AtomicInteger a, AtomicInteger b){
    a.set(b.getAndSet(a.get()));
}

String

public void swap(AtomicReference<String> a, AtomicReference<String> b){
    a.set(b.getAndSet(a.get()));
}

How about

sudo yum install php-mysql

or

sudo apt-get install php5-mysql

1. First go to Recycle Bin of your local machine.
2. Your VS code deleted files is there in Recycle Bin.
3. So, Right click on deleted files and select-> Restore option then your deleted files will be automatically restored in your VS code.

Mongo sends the complete document as a callbackobject so you can simply get it from there only.

for example

collection.save(function(err,room){
  var newRoomId = room._id;
  });

The shortest code

ChromeDriver drv = new ChromeDriver();

drv.Navigate().GoToUrl("https://stackoverflow.com/questions/6229769/execute-javascript-using-selenium-webdriver-in-c-sharp");

drv.ExecuteScript("return alert(document.title);");

If the cube is directly inside the container:

#container:hover > #cube { background-color: yellow; }

If cube is next to (after containers closing tag) the container:

#container:hover + #cube { background-color: yellow; }

If the cube is somewhere inside the container:

#container:hover #cube { background-color: yellow; }

If the cube is a sibling of the container:

#container:hover ~ #cube { background-color: yellow; }

My guess is that RAND_MAX is equal to INT_MAX and so you're overflowing it to a negative.

Just do this:

r = ((double) rand() / (RAND_MAX)) + 1;

Or even better, use C++11's random number generators.

The cleanest way I've found of doing this is with TypeScript - see How to implement class constants?

class MyClass {
    static readonly CONST1: string = "one";
    static readonly CONST2: string = "two";
    static readonly CONST3: string = "three";
}

This worked for me.

<select ng-model="somethingHere" ng-init="somethingHere='Cool'">
    <option value="Cool">Something Cool</option>
    <option value="Else">Something Else</option>
</select>

How about the regex way:

String s = "001234-a";
s = s.replaceFirst ("^0*", "");

The ^ anchors to the start of the string (I'm assuming from context your strings are not multi-line here, otherwise you may need to look into \A for start of input rather than start of line). The 0* means zero or more 0 characters (you could use 0+ as well). The replaceFirst just replaces all those 0 characters at the start with nothing.

And if, like Vadzim, your definition of leading zeros doesn't include turning "0" (or "000" or similar strings) into an empty string (a rational enough expectation), simply put it back if necessary:

String s = "00000000";
s = s.replaceFirst ("^0*", "");
if (s.isEmpty()) s = "0";

I think, is better to use it like this: (in RecyclerView adapter override just a one method)

override fun onViewAttachedToWindow(holder: ViewHolder) {
    super.onViewAttachedToWindow(holder)

    setBindAnimation(holder)
}

If You want every attach animation there in RV.

The Java Specialists newsletter (which I can unreservedly recommend) had an interesting article on this, and how to handle the InterruptedException. It's well worth reading and digesting.

If you are using responsive layout, try including this js on your code: https://github.com/scottjehl/Respond

Simply run:

npm uninstall bcrypt

Followed by:

npm install bcrypt (or npm install, if bcrypt is declared as dependency in your package.json file)

Your best bet is probably to simply re-clone from the remote repo (ie. Github or other). Unfortunately you will lose any unpushed commits and stashed changes, however your working copy should remain intact.

First make a backup copy of your local files. Then do this from the root of your working tree:

rm -fr .git
git init
git remote add origin [your-git-remote-url]
git fetch
git reset --mixed origin/master
git branch --set-upstream-to=origin/master master  

Then commit any changed files as necessary.

When you start up or just join a project based on webapplications, the design of interface is maybe good. Otherwise this should be changed. In order to Web 2.0 applications you will work with dynamic contents, many effects and other stuff.

No need to use convert. Simply list it as a quoted date in ISO 8601 format.
Like so:

select * from table1 where somedate between '2000/01/01' and '2099/12/31'

The separator needs to be a / and it needs to be surrounded by single ' quotes.

let is interesting, because it allows us to do something like this:

            for (let i = 0; i < 2; ++i) {
                console.log(count++);
            }
        }
    }
})();

Which results in counting [0, 7].

Whereas

(() => {
    var count = 0;

    for (var i = 0; i < 2; ++i) {
        for (var i = 0; i < 2; ++i) {
            for (var i = 0; i < 2; ++i) {
                console.log(count++);
            }
        }
    }
})();

Only counts [0, 1].

You can try removing the width and height attributes on the svg root element, adding preserveAspectRatio="none" viewBox="0 0 1024 800" instead. It makes a difference in Opera at least, assuming you wanted the svg to stretch to fill the entire region defined by the CSS styles.

Use CURRENT_TIMESTAMP when you need it, instead OF NOW() (which is MySQL)

If searching for a value, you will have to loop through all the data. But to minimize code involved, you can use LINQ.

Example:

Given Dictionary defined as following:

Dictionary<Int32, String> dict;

You can use following code :

// Search for all keys with given value
Int32[] keys = dict.Where(kvp => kvp.Value.Equals("SomeValue")).Select(kvp => kvp.Key).ToArray();
        
// Search for first key with given value
Int32 key = dict.First(kvp => kvp.Value.Equals("SomeValue")).Key;

There are two ways that you can achieve this. Concatenation, and shift/rotate functions.

• Concatenation is the "manual" way of doing things. You specify what part of the original signal that you want to "keep" and then concatenate on data to one end or the other. For example: tmp <= tmp(14 downto 0) & '0';

• Shift functions (logical, arithmetic): These are generic functions that allow you to shift or rotate a vector in many ways. The functions are: sll (shift left logical), srl (shift right logical). A logical shift inserts zeros. Arithmetric shifts (sra/sla) insert the left most or right most bit, but work in the same way as logical shift. Note that for all of these operations you specify what you want to shift (tmp), and how many times you want to perform the shift (n bits)

• Rotate functions: rol (rotate left), ror (rotate right). Rotating does just that, the MSB ends up in the LSB and everything shifts left (rol) or the other way around for ror.

Here is a handy reference I found (see the first page).

Surprisingly this library not mentioned yet

python package named python-slugify, which does a pretty good job of slugifying:

pip install python-slugify

Works like this:

from slugify import slugify

txt = "This is a test ---"
r = slugify(txt)
self.assertEquals(r, "this-is-a-test")

txt = "This -- is a ## test ---"
r = slugify(txt)
self.assertEquals(r, "this-is-a-test")

txt = 'C\'est déjà l\'été.'
r = slugify(txt)
self.assertEquals(r, "cest-deja-lete")

txt = 'Nín hao. Wo shì zhong guó rén'
r = slugify(txt)
self.assertEquals(r, "nin-hao-wo-shi-zhong-guo-ren")

txt = '?????????'
r = slugify(txt)
self.assertEquals(r, "kompiuter")

txt = 'jaja---lol-méméméoo--a'
r = slugify(txt)
self.assertEquals(r, "jaja-lol-mememeoo-a") 

You can convert a number to ASCII in java. example converting a number 1 (base is 10) to ASCII.

char k = Character.forDigit(1, 10);
System.out.println("Character: " + k);
System.out.println("Character: " + ((int) k));

Output:

Character: 1
Character: 49

Check this

String[] VALUES = new String[] {"AB","BC","CD","AE"};
String s;

for(int i=0; i< VALUES.length ; i++)
{
    if ( VALUES[i].equals(s) )
    { 
        // do your stuff
    } 
    else{    
        //do your stuff
    }
}

In my case there was a static variable which was not initialized. When I initialized it, the error was removed. I don't know the logic behind it but worked for me. I know its a little late but other people with similar problem might get some help.

      <authentication mode="Forms">

This configuration sends me to the login page every two minutes, which seems to controvert the earlier answers

For the interested: I've written a function that utilises preg_match so that you're able to replace from right hand side using regex.

function preg_rreplace($search, $replace, $subject) {
    preg_match_all($search, $subject, $matches, PREG_SET_ORDER);
    $lastMatch = end($matches);

    if ($lastMatch && false !== $pos = strrpos($subject, $lastMatchedStr = $lastMatch[0])) {
        $subject = substr_replace($subject, $replace, $pos, strlen($lastMatchedStr));
    }

    return $subject;
}

Or as a shorthand combination/implementation of both options:

function str_rreplace($search, $replace, $subject) {
    return (false !== $pos = strrpos($subject, $search)) ?
        substr_replace($subject, $replace, $pos, strlen($search)) : $subject;
}
function preg_rreplace($search, $replace, $subject) {
    preg_match_all($search, $subject, $matches, PREG_SET_ORDER);
    return ($lastMatch = end($matches)) ? str_rreplace($lastMatch[0], $replace, $subject) : $subject;
}

The range of floating point numbers usually exceeds the range of integers. By returning a floating point value, the functions can return a sensible value for input values that lie outside the representable range of integers.

Consider: If floor() returned an integer, what should floor(1.0e30) return?

Now, while Python's integers are now arbitrary precision, it wasn't always this way. The standard library functions are thin wrappers around the equivalent C library functions.

According to this posting by the lead Jenkins developer, Kohsuke Kawaguchi, in 2009, there is no group support for the built-in Jenkins user database. Group support is only usable when integrating Jenkins with LDAP or Active Directory. This appears to be the same in 2012.

However, as Vadim wrote in his answer, you don't need group support for the built-in Jenkins user database, thanks to the Role strategy plug-in.

You can remove the warning by adding a '@' before the mysql_connect.

@mysql_connect('localhost','root','');

but as the warning is telling you, use mysqli or PDO since the mysql extension will be removed in the future.

Fall through approach is the best one i feel.

emplace_back conforming implementation will forward arguments to the vector<Object>::value_typeconstructor when added to the vector. I recall Visual Studio didn't support variadic templates, but with variadic templates will be supported in Visual Studio 2013 RC, so I guess a conforming signature will be added.

With emplace_back, if you forward the arguments directly to vector<Object>::value_type constructor, you don't need a type to be movable or copyable for emplace_back function, strictly speaking. In the vector<NonCopyableNonMovableObject> case, this is not useful, since vector<Object>::value_type needs a copyable or movable type to grow.

But note that this could be useful for std::map<Key, NonCopyableNonMovableObject>, since once you allocate an entry in the map, it doesn't need to be moved or copied ever anymore, unlike with vector, meaning that you can use std::map effectively with a mapped type that is neither copyable nor movable.

In newer version of git (2.23+) you can use:

git switch -C master origin/master

-C is same as --force-create. Related Reference Docs

Try this: if you need pass values between the activities you use this...

This is code for Main_Activity put the values to intent

 String name="aaaa";
 Intent intent=new Intent(Main_Activity.this,Other_Activity.class);
 intent.putExtra("name", name);
 startActivity(intent);

This code for Other_Activity and get the values form intent

    Bundle b = new Bundle();
    b = getIntent().getExtras();
    String name = b.getString("name");

It seems that the version "20140702" of the example link in the question was the final version, because I downloaded this file on the 12th November 2014, i.e. the version from the 2nd of July 2014 was still the latest version on 12th of November. When I try manually all the possible versions/dates between today in this date, then I always get a page with error code "404" (file not found), which indicates that no new version was released since the 12th of November.

I think one of the major reasons is locality. Your input file size is 165G, the file's related blocks certainly distributed over multiple DataNodes, more executors can avoid network copy.

Try to set executor num equal blocks count, i think can be faster.

Yes, in near future (i write this in june 2012) you can define native css variables, without using less/sass etc ! The Webkit engine just implemented first css variable rules, so cutting edge versions of Chrome and Safari are already to work with them. See the Official Webkit (Chrome/Safari) development log with a onsite css browser demo.

Hopefully we can expect widespread browser support of native css variables in the next few months.

It's not fading to "black transparent" or "white transparent". It's just showing whatever color is "behind" the image, which is not the image's background color - that color is completely hidden by the image.

If you want to fade to black(ish), you'll need a black container around the image. Something like:

.ctr {
    margin: 0; 
    padding: 0;
    background-color: black;
    display: inline-block;
}

and

<div class="ctr"><img ... /></div>

The -fpermissive flag causes the compiler to report some things that are actually errors (but are permitted by some compilers) as warnings, to permit code to compile even if it doesn't conform to the language rules. You really should fix the underlying problem. Post the smallest, compilable code sample that demonstrates the problem.

-fpermissive
Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using -fpermissive will allow some nonconforming code to compile.

In MVC 4 If you want maxlenght in input type text ? You can !

@Html.TextBoxFor(model => model.Item3.ADR_ZIP, new { @class = "gui-input ui-oblig", @maxlength = "5" })

Suggest

>>> print vars.__doc__
vars([object]) -> dictionary

Without arguments, equivalent to locals().
With an argument, equivalent to object.__dict__.

In otherwords, it essentially just wraps __dict__

When Python2.x sees a == b, it tries the following.

• If type(b) is a new-style class, and type(b) is a subclass of type(a), and type(b) has overridden __eq__, then the result is b.__eq__(a).
• If type(a) has overridden __eq__ (that is, type(a).__eq__ isn't object.__eq__), then the result is a.__eq__(b).
• If type(b) has overridden __eq__, then the result is b.__eq__(a).
• If none of the above are the case, Python repeats the process looking for __cmp__. If it exists, the objects are equal iff it returns zero.
• As a final fallback, Python calls object.__eq__(a, b), which is True iff a and b are the same object.

If any of the special methods return NotImplemented, Python acts as though the method didn't exist.

Note that last step carefully: if neither a nor b overloads ==, then a == b is the same as a is b.

To connect from the localhost you need to add '--net host':

docker run --name some-postgres --net host -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 postgres

You can access the server directly without using exec from your localhost, by using:

psql -h localhost -p 5432 -U postgres

The advantages of EditorFor is that your code is not tied to an <input type="text". So if you decide to change something to the aspect of how your textboxes are rendered like wrapping them in a div you could simply write a custom editor template (~/Views/Shared/EditorTemplates/string.cshtml) and all your textboxes in your application will automatically benefit from this change whereas if you have hardcoded Html.TextBoxFor you will have to modify it everywhere. You could also use Data Annotations to control the way this is rendered.

Use pickle, like this: import pickle

Your code would look like this:

import pickle
mybytes = [120, 3, 255, 0, 100]
with open("bytesfile", "wb") as mypicklefile:
    pickle.dump(mybytes, mypicklefile)

To read the data back, use the pickle.load method

If we are using nodeJS, we should definitely take advantage of different libraries it provides. Inbuilt functions like each(), map(), reduce() and many more from underscoreJS reduces our efforts. Here's a sample

    var _=require("underscore");
    var fs=require("fs");

    var jsonObject=JSON.parse(fs.readFileSync('YourJson.json', 'utf8'));


    _.map( jsonObject, function(content) {
        _.map(content,function(data){
           if(data.Timestamp)
              console.log(data.Timestamp)          
           })
      })

this will remove the trailing commas and spaces

var str = ",'first string','more','even more'";
var trim = str.replace(/(^\s*,)|(,\s*$)/g, '');

Unfortunately, it appears that we can't post shares for individual topics or articles within a page. It appears Facebook just wants us to share entire pages (based on url only).

There's also their new share dialog, but even though they claim it can do all of what the old sharer.php could do, that doesn't appear to be true.

And here's Facebooks 'best practices' for sharing.

select * 
from blah 
where DatetimeField between '22/02/2009 09:00:00.000' and '23/05/2009 10:30:00.000'

Depending on the country setting for the login, the month/day may need to be swapped around.

A quick trick to use for me is using the find duplicates query SQL and changing 1 to 0 in Having expression. Like this:

SELECT COUNT([UniqueField]) AS DistinctCNT FROM
(
  SELECT First([FieldName]) AS [UniqueField]
  FROM TableName
  GROUP BY [FieldName]
  HAVING (((Count([FieldName]))>0))
);

Hope this helps, not the best way I am sure, and Access should have had this built in.

Well the data src attribute is just used for binding data for example ASP.NET ...

Maybe

SELECT count(*) FROM (
    SELECT COUNT(*) FROM Movies GROUP BY ID HAVING count(Genre) = 4
) AS the_count_total

although that would not be the sum of all the movies, just how many have 4 genre's.

So maybe you want

SELECT sum(
    SELECT COUNT(*) FROM Movies GROUP BY ID having Count(Genre) = 4
) as the_sum_total

Hope this can help!
