1. What exactly doesn't work?
2. Why are you using a 2d array?

3. If you must use a 2d array:

   int numOfPairs = 10;  String[][] array = new String[numOfPairs][2]; for(int i = 0; i < array.length; i++){     for(int j = 0; j < array[i].length; j++){         array[i] = new String[2];         array[i][0] = "original word";         array[i][1] = "rearranged word";     }    } 

Does this give you a hint?

Looks like whatever is in your Animation Drawable definition is too much memory to decode and sequence. The idea is that it loads up all the items and make them in an array and swaps them in and out of the scene according to the timing specified for each frame.

If this all can't fit into memory, it's probably better to either do this on your own with some sort of handler or better yet just encode a movie with the specified frames at the corresponding images and play the animation through a video codec.

Caveats

Here are two worthy caveats from the comments.

Either you want user to be of type User | {} or Partial<User>, or you need to redefine the User type to allow an empty object. Right now, the compiler is correctly telling you that user is not a User. – jcalz

I don't think this should be considered a proper answer because it creates an inconsistent instance of the type, undermining the whole purpose of TypeScript. In this example, the property Username is left undefined, while the type annotation is saying it can't be undefined. – Ian Liu Rodrigues

Answer

One of the design goals of TypeScript is to "strike a balance between correctness and productivity." If it will be productive for you to do this, use Type Assertions to create empty objects for typed variables.

type User = {
    Username: string;
    Email: string;
}

const user01 = {} as User;
const user02 = <User>{};

user01.Email = "[email protected]";

Here is a working example for you.

spring.jpa.hibernate.ddl-auto = update

change update to create, and run it

after run safely again change create to update so again all tables will not create and you can use your previous data

For security reason mysql -u root wont work untill you pass -p in command so try with below way

 mysql -u root -p[Enter]
 //enter your localhost password

The error is indeed fixed by inserting this with a type annotation as the first callback parameter. My attempt to do that was botched by simultaneously changing the callback into an arrow-function:

foo.on('error', (this: Foo, err: any) => { // DON'T DO THIS

It should've been this:

foo.on('error', function(this: Foo, err: any) {

or this:

foo.on('error', function(this: typeof foo, err: any) {

A GitHub issue was created to improve the compiler's error message and highlight the actual grammar error with this and arrow-functions.

I have resolve the problem by using the command:

1. Go to: C:\Users\ [PC NAME] \AppData\Local\Android\sdk\tools\bin\ (If the folder is not available then download the android SDK first, or you can install it from the android studio installation process.)
2. Shift+Left click and Press W,then Enter to open CMD on the folder path
3. Type in the cmd: sdkmanager --licenses
4. Once press enter, you need to accept all the licenses by pressing y

CHECKING THE LICENSES

1. Go to: C:\Users[PC NAME]\AppData\Local\Android\sdk\
2. Check the folder named licenses

android-googletv-license
android-sdk-license
android-sdk-preview-license
google-gdk-license
intel-android-extra-license
mips-android-sysimage-license

WAS TESTED ON CORDOVA USING THE COMMAND:

cordova build android

if you have a string of date, then you should try this.

const FORMAT = "YYYY ddd MMM DD HH:mm";

const theDate = moment("2019 Tue Apr 09 13:30", FORMAT);
// Tue Apr 09 2019 13:30:00 GMT+0300

const theDate1 = moment("2019 Tue Apr 09 13:30", FORMAT).format('LL')
// April 9, 2019

or try this :

const theDate1 = moment("2019 Tue Apr 09 13:30").format(FORMAT);

This is working for me, you might change your code like this

var responseData=x.toString();

to

var responseData=x.toString("binary");

and finally

response.write(new Buffer(toTransmit, "binary"));

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

I had the same error. The problem was in the export and import of the modules.

Example of my solution:

Controller (File: posts.js)

exports.getPosts = (req, res) => {
    res.json({
        posts: [
            { tittle: 'First posts' },
            { tittle: 'Second posts' },
        ]
    });
};

Router (File: posts.js)

const express = require('express');
const { getPosts } = require('../controllers/posts');

const routerPosts = express.Router();
routerPosts.get('/', getPosts);

exports.routerPosts = routerPosts;

Main (File: app.js)

const express = require('express');
const morgan = require('morgan');
const dotenv = require('dotenv');
const { routerPosts } = require('./routes/posts');

const app = express();
const port = process.env.PORT || 3000;

dotenv.config();

// Middleware
app.use(morgan('dev'));

app.use('/', routerPosts);

app.listen(port, () => {
    console.log(`A NodeJS API is listining on port: ${port}`);
});

Running the application (chrome output)

// 20200409002022
// http://localhost:3000/

{
  "posts": [
    {
      "tittle": "First posts"
    },
    {
      "tittle": "Second posts"
    }
  ]
}

My problem was that my company proxy was getting in the way. The solution here was to identify the Root CA / certificate chain of our proxy, (on mac) export it from the keychain in .pem format, then export a variable for node to use.

export NODE_EXTRA_CA_CERTS=/path/to/your/CA/cert.pem

Or try pure ES6 nonlodash method like this

const reducer = (array, object) => {
  array.push(object.a)
  return array
}

var objects = [{ 'a': 1 }, { 'a': 2 }];
objects.reduce(reducer, [])

It is obvious but still it was hard to figure out for me,

Please check if your mobile device has enough space to install the apk. and it is not full.

Maybe you'd like try run pip in Python shell like this:

>>> import pip
>>> pip.main(['install', 'requests'])

This will install requests package using pip.

Because pip is a module in standard library, but it isn't a built-in function(or module), so you need import it.

Other way, you should run pip in system shell(cmd. If pip is in path).

From stack trace:

HikariPool: Timeout failure pool HikariPool-0 stats (total=20, active=20, idle=0, waiting=0) Means pool reached maximum connections limit set in configuration.

The next line: HikariPool-0 - Connection is not available, request timed out after 30000ms. Means pool waited 30000ms for free connection but your application not returned any connection meanwhile.

Mostly it is connection leak (connection is not closed after borrowing from pool), set leakDetectionThreshold to the maximum value that you expect SQL query would take to execute.

otherwise, your maximum connections 'at a time' requirement is higher than 20 !

while the popular answer with extends {} works and is better than extends any, it forces the T to be an object

const foo = <T extends {}>(x: T) => x;

to avoid this and preserve the type-safety, you can use extends unknown instead

const foo = <T extends unknown>(x: T) => x;

the solution was simple -

toDoublefunc = UserDefinedFunction(lambda x: float(x),DoubleType())
changedTypedf = joindf.withColumn("label",toDoublefunc(joindf['show']))

Typing brew install cmake as you did installs cmake. Now you can type cmake and use it.

If typing cmake doesn’t work make sure /usr/local/bin is your PATH. You can see it with echo $PATH. If you don’t see /usr/local/bin in it add the following to your ~/.bashrc:

export PATH="/usr/local/bin:$PATH"

Then reload your shell session and try again.

(all the above assumes Homebrew is installed in its default location, /usr/local. If not you’ll have to replace /usr/local with $(brew --prefix) in the export line)

I could resolve this by setting the right permissions to datadir. It should be

chmod 700 /var/lib/postgresql/10/main
chown postgres.postgres /var/lib/postgresql/10/main

Problem: Wamp Won't Turn Green & VCRUNTIME140.dll error

You need C++ Redistributable for Visual Studio 2015 RC. Try to download the file, vc_redist.x64.exe from here, https://www.microsoft.com/en-us/download/details.aspx?id=48145

if you already installed then uninstalled it first

1. I installed the vc_redist.x64.exe (if you OS is 32 bit then you should download vc_redist.x86.exe)
2. then installed the wampserver (if you already installed then unsintalled it first)

If you can compile code, but Visual Studio 2015 marks 'require' functions as errors with error text cannot find name 'require' or cannot resolve symbol 'require', update TypeScript for Visual Studio 2015 to the latest version (at the moment 2.1.5) and update ReSharper (if you use it) to at least version 2016.3.2.

In 1.0, the functionality was bound to ( and tab and shift-tab, in 2.0 tab was deprecated but still functional in some unambiguous cases completing or inspecting were competing in many cases. Recommendation was to always use shift-Tab. ( was also added as deprecated as confusing in Haskell-like syntax to also push people toward Shift-Tab as it works in more cases. in 3.0 the deprecated bindings have been remove in favor of the official, present for 18+ month now Shift-Tab.

So press Shift-Tab.

I had to do the following task to rename local and remote branch:

# Rename the local branch to the new name
git branch -m <old_name> <new_name>

#  Delete the old remote branch
git push origin --delete <old_name>

# push to new remote branch - creates new remote branch
git push origin <new_name>

# set new remote branch as default remote branch for local branch
git branch --set-upstream-to=origin/<new_name> <new_name>

Seems like you posted a new question after you realized that you were dealing with a simpler problem related to size_t. I am glad that you did.

Anyways, You have a .c source file, and most of the code looks as per C standards, except that #include <iostream> and using namespace std;

C equivalent for the built-in functions of C++ standard #include<iostream> can be availed through #include<stdio.h>

1. Replace #include <iostream> with #include <stdio.h>, delete using namespace std;

2. With #include <iostream> taken off, you would need a C standard alternative for cout << endl;, which can be done by printf("\n"); or putchar('\n');
   Out of the two options, printf("\n"); works the faster as I observed.

   When used printf("\n"); in the code above in place of cout<<endl;

   $ time ./thread.exe

Here's an awesome/really crappy way of extending multiple classes. I'm utilizing a couple functions that Babel put into my transpiled code. The function creates a new class that inherits class1, and class1 inherits class2, and so on. It has its issues, but a fun idea.

var _typeof = typeof Symbol === 'function' && typeof Symbol.iterator === 'symbol' ? function (obj) {
  return typeof obj
} : function (obj) {
  return obj && typeof Symbol === 'function' && obj.constructor === Symbol ? 'symbol' : typeof obj
}

function _inherits (subClass, superClass) {
  if (typeof superClass !== 'function' && superClass !== null) {
    throw new TypeError('Super expression must either be null or a function, not ' + (
      typeof superClass === 'undefined' ? 'undefined' : _typeof(superClass)))
  }
  subClass.prototype = Object.create(
    superClass && superClass.prototype,
    {
      constructor: {
        value: subClass,
        enumerable: false,
        writable: true,
        configurable: true
      }
    })
  if (superClass) {
    Object.setPrototypeOf
    ? Object.setPrototypeOf(subClass, superClass)
    : subClass.__proto__ = superClass.__proto__  // eslint-disable-line no-proto
  }
}

function _m (...classes) {
  let NewSuperClass = function () {}
  let c1 = NewSuperClass
  for (let c of classes) {
    _inherits(c1, c)
    c1 = c
  }
  return NewSuperClass
}

Change the button to

<button id="search">Search</button>

and add the following script

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('#search').click(function() {
  var keyWord = $('#Keyword').val();
  $('#searchResults').load(url, { searchText: keyWord });
})

and modify the controller method to accept the search text

public ActionResult DisplaySearchResults(string searchText)
{
  var model = // build list based on parameter searchText
   return PartialView("SearchResults", model);
}

The jQuery .load method calls your controller method, passing the value of the search text and updates the contents of the <div> with the partial view.

Side note: The use of a <form> tag and @Html.ValidationSummary() and @Html.ValidationMessageFor() are probably not necessary here. Your never returning the Index view so ValidationSummary makes no sense and I assume you want a null search text to return all results, and in any case you do not have any validation attributes for property Keyword so there is nothing to validate.

Edit

Based on OP's comments that SearchCriterionModel will contain multiple properties with validation attributes, then the approach would be to include a submit button and handle the forms .submit() event

<input type="submit" value="Search" />

var url = '@Url.Action("DisplaySearchResults", "Search")';
$('form').submit(function() {
  if (!$(this).valid()) { 
    return false; // prevent the ajax call if validation errors
  }
  var form = $(this).serialize();
  $('#searchResults').load(url, form);
  return false; // prevent the default submit action
})

and the controller method would be

public ActionResult DisplaySearchResults(SearchCriterionModel criteria)
{
  var model = // build list based on the properties of criteria
  return PartialView("SearchResults", model);
}

I did different tests on the typescript playground:

http://www.typescriptlang.org/play/

let a;
let b = null;
let c = "";
var output = "";

if (a == null) output += "a is null or undefined\n";
if (b == null) output += "b is null or undefined\n";
if (c == null) output += "c is null or undefined\n";
if (a != null) output += "a is defined\n";
if (b != null) output += "b is defined\n";
if (c != null) output += "c is defined\n";
if (a) output += "a is defined (2nd method)\n";
if (b) output += "b is defined (2nd method)\n";
if (c) output += "c is defined (2nd method)\n";

console.log(output);

gives:

a is null or undefined
b is null or undefined
c is defined

so:

• checking if (a == null) is right to know if a is null or undefined
• checking if (a != null) is right to know if a is defined
• checking if (a) is wrong to know if a is defined

For me, this issue was caused in my build system (Travis CI) by doing something kind of dumb in my .travis.yml file. In effect, I was calling npm install before nvm use 0.12, and this was causing node-sass to be built for 0.10 instead of 0.12. My solution was simply moving nvm use out of the .travis.yml file’s before_script section to before the npm install command, which was in the before_install section.

In your case, it is likely that whatever process you are starting with gulp is using a different version of node (than what you would expect).

This is how you can add a textField text change listener using Swift 3:

Declare your class as UITextFieldDelegate

override func viewDidLoad() {
    super.viewDidLoad()

    textField.delegate = self

    textField.addTarget(self, action: #selector(UITextFieldDelegate.textFieldShouldEndEditing(_:)), for: UIControlEvents.editingChanged)
}

Then just traditionally add a textFieldShouldEndEditing function:

func textFieldShouldEndEditing(_ textField: UITextField) -> Bool { // do stuff
        return true 
}

So it looks like there are a few things going wrong here. Based on your post it looks like you are attempting to support file uploads using the connect-multiparty middleware. What this middleware does is take the uploaded file, write it to the local filesystem and then sets req.files to the the uploaded file(s).

The configuration of your route looks fine, the problem looks to be with your items.upload() function. In particular with this part:

var params = {
  Key: file.name,
  Body: file
};

As I mentioned at the beginning of my answer connect-multiparty writes the file to the local filesystem, so you'll need to open the file and read it, then upload it, and then delete it on the local filesystem.

That said you could update your method to something like the following:

var fs = require('fs');
exports.upload = function (req, res) {
    var file = req.files.file;
    fs.readFile(file.path, function (err, data) {
        if (err) throw err; // Something went wrong!
        var s3bucket = new AWS.S3({params: {Bucket: 'mybucketname'}});
        s3bucket.createBucket(function () {
            var params = {
                Key: file.originalFilename, //file.name doesn't exist as a property
                Body: data
            };
            s3bucket.upload(params, function (err, data) {
                // Whether there is an error or not, delete the temp file
                fs.unlink(file.path, function (err) {
                    if (err) {
                        console.error(err);
                    }
                    console.log('Temp File Delete');
                });

                console.log("PRINT FILE:", file);
                if (err) {
                    console.log('ERROR MSG: ', err);
                    res.status(500).send(err);
                } else {
                    console.log('Successfully uploaded data');
                    res.status(200).end();
                }
            });
        });
    });
};

What this does is read the uploaded file from the local filesystem, then uploads it to S3, then it deletes the temporary file and sends a response.

There's a few problems with this approach. First off, it's not as efficient as it could be, as for large files you will be loading the entire file before you write it. Secondly, this process doesn't support multi-part uploads for large files (I think the cut-off is 5 Mb before you have to do a multi-part upload).

What I would suggest instead is that you use a module I've been working on called S3FS which provides a similar interface to the native FS in Node.JS but abstracts away some of the details such as the multi-part upload and the S3 api (as well as adds some additional functionality like recursive methods).

If you were to pull in the S3FS library your code would look something like this:

var fs = require('fs'),
    S3FS = require('s3fs'),
    s3fsImpl = new S3FS('mybucketname', {
        accessKeyId: XXXXXXXXXXX,
        secretAccessKey: XXXXXXXXXXXXXXXXX
    });

// Create our bucket if it doesn't exist
s3fsImpl.create();

exports.upload = function (req, res) {
    var file = req.files.file;
    var stream = fs.createReadStream(file.path);
    return s3fsImpl.writeFile(file.originalFilename, stream).then(function () {
        fs.unlink(file.path, function (err) {
            if (err) {
                console.error(err);
            }
        });
        res.status(200).end();
    });
};

What this will do is instantiate the module for the provided bucket and AWS credentials and then create the bucket if it doesn't exist. Then when a request comes through to upload a file we'll open up a stream to the file and use it to write the file to S3 to the specified path. This will handle the multi-part upload piece behind the scenes (if needed) and has the benefit of being done through a stream, so you don't have to wait to read the whole file before you start uploading it.

If you prefer, you could change the code to callbacks from Promises. Or use the pipe() method with the event listener to determine the end/errors.

If you're looking for some additional methods, check out the documentation for s3fs and feel free to open up an issue if you are looking for some additional methods or having issues.

I face the same problem but that was after I had updated to appcompatv23.2.0. I tried all the above suggestions but dint work. Then I proceeded to my Gradle file and replaced:

dependencies {
compile 'com.android.support:appcompat-v7:23.2.0’
compile 'com.android.support:design:23.2.0'

}

with:

dependencies {
compile 'com.android.support:appcompat-v7:23.0.1'
compile 'com.android.support:design:23.0.1'
}

Rebuild the project and the issue was gone. It could be an issue with app compact v23.2.0, hopefully a better solution coming up so we can work with the new update.

Hope this helps. Thank you.

I got this error when getting a value from NSUserDefaults. The following gives error:

let arr = defaults.objectForKey("myArray")

What fixed the error was to cast the type to the correct type stored in NSUserDefaults. The following gives no error:

let arr = defaults.objectForKey("myArray") as! Array<String>

That means /usr/local/mysql/bin/mysql is not in the PATH variable..

Either execute /usr/local/mysql/bin/mysql to get your mysql shell,

or type this in your terminal:

PATH=$PATH:/usr/local/mysql/bin

to add that to your PATH variable so you can just run mysql without specifying the path

The filename should go at the end of the path to the directory. That is, it should be the full path to the file. You are doing this from a command line, and you have a working directory for that command line (on your local machine), this is the directory that your file will be downloaded to. The final argument in your command is only what you want the name of the file to be. So, first, change directory to where you want the file to land. I'm doing this from git bash on a Windows machine, so it looks like this:

cd C:\Users\myUserName\Downloads

Now that I have my working directory where I want the file to go:

scp -i 'c:\Users\myUserName\.ssh\AWSkeyfile.pem' [email protected]:/home/ec2-user/IwantThisFile.tar IgotThisFile.tar

Or, in your case:

cd /local/path/where/you/want/the/file/to/land
scp [email protected]:/local/machine/path/to/directory/filename filename

func helperCapitalizeFirstLetter(stringToBeCapd:String)->String{
    let capString = stringToBeCapd.substringFromIndex(stringToBeCapd.startIndex).capitalizedString
    return capString
}

Also works just pass your string in and get a capitalized one back.

Slightly more succinct syntax version of Daniel Krom's Swift 2 answer, using a trailing closure and shorthand argument name, which appears to be based on Airspeed Velocity's original answer:

func uniq<S: SequenceType, E: Hashable where E == S.Generator.Element>(source: S) -> [E] {
  var seen = [E: Bool]()
  return source.filter { seen.updateValue(true, forKey: $0) == nil }
}

Example of implementing a custom type that can be used with uniq(_:) (which must conform to Hashable, and thus Equatable, because Hashable extends Equatable):

func ==(lhs: SomeCustomType, rhs: SomeCustomType) -> Bool {
  return lhs.id == rhs.id // && lhs.someOtherEquatableProperty == rhs.someOtherEquatableProperty
}

struct SomeCustomType {

  let id: Int

  // ...

}

extension SomeCustomType: Hashable {

  var hashValue: Int {
    return id
  }

}

In the above code...

id, as used in the overload of ==, could be any Equatable type (or method that returns an Equatable type, e.g., someMethodThatReturnsAnEquatableType()). The commented-out code demonstrates extending the check for equality, where someOtherEquatableProperty is another property of an Equatable type (but could also be a method that returns an Equatable type).

id, as used in the hashValue computed property (required to conform to Hashable), could be any Hashable (and thus Equatable) property (or method that returns a Hashable type).

Example of using uniq(_:):

var someCustomTypes = [SomeCustomType(id: 1), SomeCustomType(id: 2), SomeCustomType(id: 3), SomeCustomType(id: 1)]

print(someCustomTypes.count) // 4

someCustomTypes = uniq(someCustomTypes)

print(someCustomTypes.count) // 3

On Windows, pip lives in C:\[pythondir]\scripts.

So you'll need to add that to your system path in order to run it from the command prompt. You could alternatively cd into that directory each time, but that's a hassle.

See the top answer here for info on how to do that: Adding Python Path on Windows 7

Also, that is a terrifying way to install pip. Grab it from Christophe Gohlke. Grab everything else from there for that matter. http://www.lfd.uci.edu/~gohlke/pythonlibs/

I've provide an example not sure if this is what you're after.

var completionHandler: (_ value: Float) -> ()

func printFloat(value: Float) {
    print(value)
}

completionHandler = printFloat

completionHandler(5)

It simply prints 5 using the completionHandler variable declared.

you can also use a namedQuery named findAll for all your entities and call it in your generic FindAll with

entityManager.createNamedQuery(persistentClass.getSimpleName()+"findAll").getResultList();

It should be exclude module: 'net.milkbowl:vault:1.2.27'(add module:) as explained in documentation for DependencyHandler linked from http://www.gradle.org/docs/current/javadoc/org/gradle/api/Project.html#dependencies(groovy.lang.Closure) because ModuleDependency.exclude(java.util.Map) method is used.

Edit (for ASP.NET)

After you edited your question it's cler you're using ASP.NET. Things are pretty different there (because in that case a roundtrip to server is pretty discouraged). You can do same things with JavaScript (but to handle globalization with toUpperCase() may be a pain) or you can use CSS classes (relying on browsers implementation). Simply declare this CSS rule:

.upper-case
{
    text-transform: uppercase
}

And add upper-case class to your text-box:

<asp:TextBox ID="TextBox1" CssClass="upper-case" runat="server"/>

General (Old) Answer

but it capitalize characters after pressing Enter key.

It depends where you put that code. If you put it in, for example, TextChanged event it'll make upper case as you type.

You have a property that do exactly what you need: CharacterCasing:

TextBox1.CharacterCasing = CharacterCasing.Upper;

It works more or less but it doesn't handle locales very well. For example in German language ß is SS when converted in upper case (Institut für Deutsche Sprache) and this property doesn't handle that.

You may mimic CharacterCasing property adding this code in KeyPress event handler:

e.KeyChar = Char.ToUpper(e.KeyChar);

Unfortunately .NET framework doesn't handle this properly and upper case of sharp s character is returned unchanged. An upper case version of ß exists and it's ? and it may create some confusion, for example a word containing "ss" and another word containing "ß" can't be distinguished if you convert in upper case using "SS"). Don't forget that:

However, in 2010 the use of the capital sharp s became mandatory in official documentation when writing geographical names in all-caps.

There isn't much you can do unless you add proper code for support this (and others) subtle bugs in .NET localization. Best advice I can give you is to use a custom dictionary per each culture you need to support.

Finally don't forget that this transformation may be confusing for your users: in Turkey, for example, there are two different versions of i upper case letter.

If text processing is important in your application you can solve many issues using specialized DLLs for each locale you support like Word Processors do.

What I usually do is to do not use standard .NET functions for strings when I have to deal with culture specific issues (I keep them only for text in invariant culture). I create a Unicode class with static methods for everything I need (character counting, conversions, comparison) and many specialized derived classes for each supported language. At run-time that static methods will user current thread culture name to pick proper implementation from a dictionary and to delegate work to that. A skeleton may be something like this:

abstract class Unicode
{
    public static string ToUpper(string text)
    {
        return GetConcreteClass().ToUpperCore(text);
    }

    protected virtual string ToUpperCore(string text)
    {
        // Default implementation, overridden in derived classes if needed
        return text.ToUpper();
    }

    private Dictionary<string, Unicode> _implementations;

    private Unicode GetConcreteClass()
    {
        string cultureName = Thread.Current.CurrentCulture.Name;

        // Check if concrete class has been loaded and put in dictionary
        ...

        return _implementations[cultureName];
    }
}

I'll then have an implementation specific for German language:

sealed class German : Unicode
{
    protected override string ToUpperCore(string text)
    {
        // Very naive implementation, just to provide an example
        return text.ToUpper().Replace("ß", "?");
    }
}

True implementation may be pretty more complicate (not all OSes supports upper case ?) but take as a proof of concept. See also this post for other details about Unicode issues on .NET.

I'm guessing you've installed Code::Blocks but not installed or set up GCC yet. I'm assuming you're on Windows, based on your comments about Visual Studio; if you're on a different platform, the steps for setting up GCC should be similar but not identical.

First you'll need to download GCC. There are lots and lots of different builds; personally, I use the 64-bit build of TDM-GCC. The setup for this might be a bit more complex than you'd care for, so you can go for the 32-bit version or just grab a preconfigured Code::Blocks/TDM-GCC setup here.

Once your setup is done, go ahead and launch Code::Blocks. You don't need to create a project or write any code yet; we're just here to set stuff up or double-check your setup, depending on how you opted to install GCC.

Go into the Settings menu, then select Global compiler settings in the sidebar, and select the Toolchain executables tab. Make sure the Compiler's installation directory textbox matches the folder you installed GCC into. For me, this is C:\TDM-GCC-64. Your path will vary, and this is completely fine; just make sure the path in the textbox is the same as the path you installed to. Pay careful attention to the warning note Code::Blocks shows: this folder must have a bin subfolder which will contain all the relevant GCC executables. If you look into the folder the textbox shows and there isn't a bin subfolder there, you probably have the wrong installation folder specified.

Now, in that same Toolchain executables screen, go through the individual Program Files boxes one by one and verify that the filenames shown in each are correct. You'll want some variation of the following:

• C compiler: gcc.exe (mine shows x86_64-w64-mingw32-gcc.exe)
• C++ compiler: g++.exe (mine shows x86_64-w64-mingw32-g++.exe)
• Linker for dynamic libs: g++.exe (mine shows x86_64-w64-mingw32-g++.exe)
• Linker for static libs: gcc-ar.exe (mine shows x86_64-w64-mingw32-gcc-ar.exe)
• Debugger: GDB/CDB debugger: Default
• Resource compiler: windres.exe (mine shows windres.exe)
• Make program: make.exe (mine shows mingw32-make.exe)

Again, note that all of these files are in the bin subfolder of the folder shown in the Compiler installation folder box - if you can't find these files, you probably have the wrong folder specified. It's okay if the filenames aren't a perfect match, though; different GCC builds might have differently prefixed filenames, as you can see from my setup.

Once you're done with all that, go ahead and click OK. You can restart Code::Blocks if you'd like, just to confirm the changes will stick even if there's a crash (I've had occasional glitches where Code::Blocks will crash and forget any settings changed since the last launch).

Now, you should be all set. Go ahead and try your little section of code again. You'll want int main(void) to be int main(), but everything else looks good. Try building and running it and see what happens. It should run successfully.

uint8, uint16, uint32, and uint64 are probably Microsoft-specific types.

As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>: uint8_t, uint16_t, uint32_t, and uint64_t. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>, at least as of Visual Studio 2010, but older code may use uint8 et al.

The predefined types char, short, int et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.

char is almost always exactly 8 bits, but it's permitted to be wider. And plain char may be either signed or unsigned.

uint8_t is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char, though it might be a typedef for plain char if plain char happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t will not be defined at all.

Similarly, each uintN_t type is an unsigned type that's exactly N bits wide.

In addition, <stdint.h> defines corresponding signed intN_t types, as well as int_fastN_t and int_leastN_t types that are at least the specified width.

The [u]intN_t types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t types are required to use a 2's-complement representation.

Although uint32_t might be the same as unsigned int, for example, you shouldn't assume that. Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.

(And no, uint64 or uint64_t is not the same as double; double is a floating-point type.)

Try This :

In HTML and JS :

// Convert Password Field To Text On Hover._x000D_
  var passField = $('input[type=password]');_x000D_
  $('.show-pass').hover(function() {_x000D_
      passField.attr('type', 'text');_x000D_
  }, function() {_x000D_
    passField.attr('type', 'password');_x000D_
  })

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://stackpath.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>_x000D_
<!-- An Input PassWord Field With Eye Font-Awesome Class -->_x000D_
<input type="password" placeholder="Type Password">_x000D_
      <i class="show-pass fa fa-eye fa-lg"></i>

Since the fields are empty they are not valid, so the ng-invalid and ng-invalid-required classes are added properly.

You can use the class ng-pristine to check out whether the fields have already been used or not.

I faced a similar problem and than got the solution in the package name. I kept the package name as java.basics. In the console I got a hint for that as it clearly said Prohibited package name. So I changed package name and it worked.

I Faced the same issue while installing a setup using a jar file. Solution thta worked for me is

1. open command prompt as administrator
2. Go to jdk bin directory (Ex.C:\Program Files\Java\jdk1.8.0_73\bin)
3. now execute java -jar <<jar fully qualified path>>

It worked for me :)

You can run below commands. I believe this is what you want!

Note: Make sure the port 8080 is open. If not, kill the process that is using 8080 port using sudo kill -9 $(sudo lsof -t -i:8080)

 ./catalina.sh run

I have a slightly different setup, but think my solution will help you out.

I have a Windows 8 Machine, Python 2.7 installed and running my stuff through eclipse.

Some Background:

When I did an easy install it tries to install MySQL-python 1.2.5 which failed with an error: Unable to find vcvarsall.bat. I did an easy_install of pip and tried the pip install which also failed with a similar error. They both reference vcvarsall.bat which is something to do with visual studio, since I don't have visual studio on my machine, it left me looking for a different solution, which I share below.

The Solution:

1. Reinstall python 2.7.8 from 2.7.8 from https://www.python.org/download this will add any missing registry settings, which is required by the next install.
2. Install 1.2.4 from http://pypi.python.org/pypi/MySQL-python/1.2.4

After I did both of those installs I was able to query my MySQL db through eclipse.

I had the same problem, but i solved it from Java Control Panel-->Security-->SecurityLevel:MEDIUM. Just so, no Manage certificates, imports ,exports etc..

Something like this (not tested, but should work)

Pass this as parameter in Html:

<input type="text" placeholder="some text" class="search" onkeydown="search(this)"/>

And alert the value of the parameter passed into the search function:

function search(e){
  alert(e.value);
}

I use this function htmlentities($string):

$msg = "<script>alert("hello")</script> <h1> Hello World </h1>"
$msg = htmlentities($msg);
echo $msg;

typedef defines a new data type. So you can have:

typedef char* my_string;
typedef struct{
  int member1;
  int member2;
} my_struct;

So now you can declare variables with these new data types

my_string s;
my_struct x;

s = "welcome";
x.member1 = 10;

For enum, things are a bit different - consider the following examples:

enum Ranks {FIRST, SECOND};
int main()
{
   int data = 20;
   if (data == FIRST)
   {
      //do something
   }
}

using typedef enum creates an alias for a type:

typedef enum Ranks {FIRST, SECOND} Order;
int main()
{
   Order data = (Order)20;  // Must cast to defined type to prevent error

   if (data == FIRST)
   {
      //do something
   }
}

I faced the same problem after migrating a database from online server to localhost. The schema changed so I had to define the schema manually for each table:

@Entity
@Table(name = "ESBCORE_DOMAIN", schema = "SYS")

SIMPLEST ANSWER

just spread the set inside []

let mySet = new Set()
mySet.add(1)
mySet.add(5)
mySet.add(5) 
let arr = [...mySet ]

Result: [1,5]

I will add MetaKey as well, as I am using MacOS

input.addEventListener("keypress", (e) => {
    const key = e.key;
    if (!(e.metaKey || e.ctrlKey) && key.length === 1 && !/\d\./.test(key)) {
        e.preventDefault();
    }
}

Or, you can try !isNaN(parseFloat(key))

You should use a callback parameter:

function Typer(callback)
{
    var srcText = 'EXAMPLE ';
    var i = 0;
    var result = srcText[i];
    var interval = setInterval(function() {
        if(i == srcText.length - 1) {
            clearInterval(interval);
            callback();
            return;
        }
        i++;
        result += srcText[i].replace("\n", "<br />");
        $("#message").html(result);
    },
    100);
    return true;


}

function playBGM () {
    alert("Play BGM function");
    $('#bgm').get(0).play();
}

Typer(function () {
    playBGM();
});

// or one-liner: Typer(playBGM);

So, you pass a function as parameter (callback) that will be called in that if before return.

Also, this is a good article about callbacks.

JSFIDDLE

From the OP:

I finally reinstalled it from Java for OS X 2013-005. It solved this issue.

Short ONELINER:

<input onkeypress="return /[a-z]/i.test(event.key)" >

For all unicode letters try this regexp: /\p{L}/u (but ... this) - and here is working example :)

You are getting that error because the keytool executable is under the bin directory, not the lib directory in your example. And you will need to add the location of your keystore as well in the command line. There is a pretty good reference to all of this here - Jrun Help / Import certificates | Certificate stores | ColdFusion

The default truststore is the JRE's cacerts file. This file is typically located in the following places:

• Server Configuration:

  cf_root/runtime/jre/lib/security/cacerts

• Multiserver/J2EE on JRun 4 Configuration:

  jrun_root/jre/lib/security/cacerts

• Sun JDK installation:

  jdk_root/jre/lib/security/cacerts

• Consult documentation for other J2EE application servers and JVMs

The keytool is part of the Java SDK and can be found in the following places:

• Server Configuration:

  cf_root/runtime/bin/keytool

• Multiserver/J2EE on JRun 4 Configuration:

  jrun_root/jre/bin/keytool

• Sun JDK installation:

  jdk_root/bin/keytool

• Consult documentation for other J2EE application servers and JVMs

So if you navigate to the directory where the keytool executable is located your command line would look something like this:

keytool -list -v -keystore JAVA_HOME\jre\lib\security\cacert -storepass changeit

You will need to supply pathing information depending on where you run the keytool command from and where your certificate file resides.

Also, be sure you are updating the correct cacerts file that ColdFusion is using. In case you have more than one JRE installed on that server. You can verify the JRE ColdFusion is using from the administrator under the 'System Information'. Look for the Java Home line.

use value instead of query (must specify index of node to return in the XQuery as well as passing the sql data type to return as the second parameter):

select
    xt.Id
    , x.m.value( '@id[1]', 'varchar(max)' ) MetricId
from
    XmlTest xt
    cross apply xt.XmlData.nodes( '/Sqm/Metrics/Metric' ) x(m)

I wanted a directive that could be limited in range by min and max attributes like so:

<input type="text" integer min="1" max="10" />

so I wrote the following:

.directive('integer', function() {
    return {
        restrict: 'A',
        require: '?ngModel',
        link: function(scope, elem, attr, ngModel) {
            if (!ngModel)
                return;

            function isValid(val) {
                if (val === "")
                    return true;

                var asInt = parseInt(val, 10);
                if (asInt === NaN || asInt.toString() !== val) {
                    return false;
                }

                var min = parseInt(attr.min);
                if (min !== NaN && asInt < min) {
                    return false;
                }

                var max = parseInt(attr.max);
                if (max !== NaN && max < asInt) {
                    return false;
                }

                return true;
            }

            var prev = scope.$eval(attr.ngModel);
            ngModel.$parsers.push(function (val) {
                // short-circuit infinite loop
                if (val === prev)
                    return val;

                if (!isValid(val)) {
                    ngModel.$setViewValue(prev);
                    ngModel.$render();
                    return prev;
                }

                prev = val;
                return val;
            });
        }
    };
});

Fixed it. I needed to run libtoolize in the directory, then re-run:

• aclocal

• autoheader

An example of how you could do this:

Some notes:

• LoggingHandler intercepts the request before it handles it to HttpClientHandler which finally writes to the wire.

• PostAsJsonAsync extension internally creates an ObjectContent and when ReadAsStringAsync() is called in the LoggingHandler, it causes the formatter inside ObjectContent to serialize the object and that's the reason you are seeing the content in json.

Logging handler:

public class LoggingHandler : DelegatingHandler
{
    public LoggingHandler(HttpMessageHandler innerHandler)
        : base(innerHandler)
    {
    }

    protected override async Task<HttpResponseMessage> SendAsync(HttpRequestMessage request, CancellationToken cancellationToken)
    {
        Console.WriteLine("Request:");
        Console.WriteLine(request.ToString());
        if (request.Content != null)
        {
            Console.WriteLine(await request.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        HttpResponseMessage response = await base.SendAsync(request, cancellationToken);

        Console.WriteLine("Response:");
        Console.WriteLine(response.ToString());
        if (response.Content != null)
        {
            Console.WriteLine(await response.Content.ReadAsStringAsync());
        }
        Console.WriteLine();

        return response;
    }
}

Chain the above LoggingHandler with HttpClient:

HttpClient client = new HttpClient(new LoggingHandler(new HttpClientHandler()));
HttpResponseMessage response = client.PostAsJsonAsync(baseAddress + "/api/values", "Hello, World!").Result;

Output:

Request:
Method: POST, RequestUri: 'http://kirandesktop:9095/api/values', Version: 1.1, Content: System.Net.Http.ObjectContent`1[

public View getView(int position, View convertView, ViewGroup parent) {

        row = inflater.inflate(layoutResourceId, parent, false);

It would seem that is.nan doesn't actually have a method for data frames, unlike is.na. So, let's fix that!

is.nan.data.frame <- function(x)
do.call(cbind, lapply(x, is.nan))

data123[is.nan(data123)] <- 0

Use $dirty flag to show the error only after user interacted with the input:

<div>
  <input type="email" name="email" ng-model="user.email" required />
  <span ng-show="form.email.$dirty && form.email.$error.required">Email is required</span>
</div>

If you want to trigger the errors only after the user has submitted the form than you may use a separate flag variable as in:

<form ng-submit="submit()" name="form" ng-controller="MyCtrl">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="(form.email.$dirty || submitted) && form.email.$error.required">
      Email is required
    </span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  } 
};

Then, if all that JS inside ng-showexpression looks too much for you, you can abstract it into a separate method:

function MyCtrl($scope){
  $scope.submit = function(){
    // Set the 'submitted' flag to true
    $scope.submitted = true;
    // Send the form to server
    // $http.post ...
  }

  $scope.hasError = function(field, validation){
    if(validation){
      return ($scope.form[field].$dirty && $scope.form[field].$error[validation]) || ($scope.submitted && $scope.form[field].$error[validation]);
    }
    return ($scope.form[field].$dirty && $scope.form[field].$invalid) || ($scope.submitted && $scope.form[field].$invalid);
  };

};

<form ng-submit="submit()" name="form">
  <div>
    <input type="email" name="email" ng-model="user.email" required />
    <span ng-show="hasError('email', 'required')">required</span>
  </div>

  <div>
    <button type="submit">Submit</button>
  </div>
</form>

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

I was getting this error after adding the include files and linking the library. It was because the lib was built with non-unicode and my application was unicode. Matching them fixed it.

You can use a function like strtol() which will convert a character array to a long.

It has a parameter which is a way to detect the first character that didn't convert properly. If this is anything other than the end of the string, then you have a problem.

See the following program for an example:

#include <stdio.h>
#include <stdlib.h>

int main( int argc, char *argv[]) {
    int i;
    long val;
    char *next;

    // Process each argument given.

    for (i = 1; i < argc; i++) {
        // Get value with failure detection.

        val = strtol (argv[i], &next, 10);

        // Check for empty string and characters left after conversion.

        if ((next == argv[i]) || (*next != '\0')) {
            printf ("'%s' is not valid\n", argv[i]);
        } else {
            printf ("'%s' gives %ld\n", argv[i], val);
        }
    }

    return 0;
}

Running this, you can see it in operation:

pax> testprog hello "" 42 12.2 77x

'hello' is not valid
'' is not valid
'42' gives 42
'12.2' is not valid
'77x' is not valid

In summary;

git init
git status
git add "*"

This will only work in C++. Functions in structs are not a feature of C.

Same goes for your client.AddClient(); call ... this is a call for a member function, which is object oriented programming, i.e. C++.

Convert your source to a .cpp file and make sure you are compiling accordingly.

If you need to stick to C, the code below is (sort of) the equivalent:

typedef struct client_t client_t, *pno;
struct client_t
{
        pid_t pid;
        char password[TAM_MAX]; // -> 50 chars
        pno next;

};


pno AddClient(pno *pclient) 
{
    /* code */
}


int main()
{

    client_t client;

    //code ..

    AddClient(client);

}

Create a new keypair: (go with the defaults)

ssh-keygen

Copy the public key to the server: (password for the last time)

ssh-copy-id [email protected]

From now on the server should recognize your key and not ask you for the password anymore:

ssh [email protected]

This is a one-liner alternative to Mike Q's function:

secs_to_human() {
    echo "$(( ${1} / 3600 ))h $(( (${1} / 60) % 60 ))m $(( ${1} % 60 ))s"
}

Check your .bash_profile, .zshrc, or .profile file. You most likely had a problem during the installation.

You should have the following at the end of one of those files.

[[ -s $HOME/.nvm/nvm.sh ]] && . $HOME/.nvm/nvm.sh  # This loads NVM

The . $HOME/.nvm/nvm.sh is the same as source $HOME/.nvm/nvm.sh

See: Sourcing a File

You can also check to see if you have a .nvm folder.

ls -a | grep .nvm

If you're missing that folder then the installation failed to run the git command. This could be due to being behind a proxy. Try running the following instead.

git clone http://github.com/creationix/nvm.git .nvm

pip is designed to upgrade python packages and not to upgrade python itself. pip shouldn't try to upgrade python when you ask it to do so.

Don't type pip install python but use an installer instead.

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

This code shows the example how to prevent entering non digit symbols.

angular.module('app').
  directive('onlyDigits', function () {

    return {
        restrict: 'A',
        require: '?ngModel',
        link: function (scope, element, attrs, modelCtrl) {
            modelCtrl.$parsers.push(function (inputValue) {
                if (inputValue == undefined) return '';
                var transformedInput = inputValue.replace(/[^0-9]/g, '');
                if (transformedInput !== inputValue) {
                    modelCtrl.$setViewValue(transformedInput);
                    modelCtrl.$render();
                }
                return transformedInput;
            });
        }
    };
});

You haven't posted the findvertex method, but Access Reading Violation with an offset like 0x00000048 means that the Vertex* f; in your getCost function is receiving null, and when trying to access the member adj in the null Vertex pointer (that is, in f), it is offsetting to adj (in this case, 72 bytes ( 0x48 bytes in decimal )), it's reading near the 0 or null memory address.

Doing a read like this violates Operating-System protected memory, and more importantly means whatever you're pointing at isn't a valid pointer. Make sure findvertex isn't returning null, or do a comparisong for null on f before using it to keep yourself sane (or use an assert):

assert( f != null ); // A good sanity check

EDIT:

If you have a map for doing something like a find, you can just use the map's find method to make sure the vertex exists:

Vertex* Graph::findvertex(string s)
{
    vmap::iterator itr = map1.find( s );
    if ( itr == map1.end() )
    {
        return NULL;
    }
    return itr->second;
}

Just make sure you're still careful to handle the error case where it does return NULL. Otherwise, you'll keep getting this access violation.

The existing answers missed an option, so here's a complete list:

// 1. Explicitly declare the type
var arr: Criminal[] = [];

// 2. Via type assertion
var arr = <Criminal[]>[];
var arr = [] as Criminal[];

// 3. Using the Array constructor
var arr = new Array<Criminal>();

1. Explicitly specifying the type is the general solution for whenever type inference fails for a variable declaration.

2. The advantage of using a type assertion (sometimes called a cast, but it's not really a cast in TypeScript) works for any expression, so it can be used even when no variable is declared. There are two syntaxes for type assertions, but only the latter will work in combination with JSX if you care about that.

3. Using the Array constructor is something that will only help you in this specific use case, but which I personally find the most readable. However, there is a slight performance impact at runtime*. Also, if someone were crazy enough to redefine the Array constructor, the meaning could change.

It's a matter of personal preference, but I find the third option the most readable. In the vast majority of cases the mentioned downsides would be negligible and readability is the most important factor.

*: Fun fact; at the time of writing the performance difference was 60% in Chrome, while in Firefox there was no measurable performance difference.

ssize_t is not included in the standard and isn't portable. size_t should be used when handling the size of objects (there's ptrdiff_t too, for pointer differences).

I think that your reasoning is sound. But in practice I have found that it is far more common to omit the === comparison. I think that there are three reasons for that:

1. It does not usually add to the meaning of the expression - that's in cases where the value is known to be boolean anyway.
2. Because there is a great deal of type-uncertainty in JavaScript, forcing a type check tends to bite you when you get an unexpected undefined or null value. Often you just want your test to fail in such cases. (Though I try to balance this view with the "fail fast" motto).
3. JavaScript programmers like to play fast-and-loose with types - especially in boolean expressions - because we can.

Consider this example:

var someString = getInput();
var normalized = someString && trim(someString);  
// trim() removes leading and trailing whitespace

if (normalized) {
    submitInput(normalized);
}

I think that this kind of code is not uncommon. It handles cases where getInput() returns undefined, null, or an empty string. Due to the two boolean evaluations submitInput() is only called if the given input is a string that contains non-whitespace characters.

In JavaScript && returns its first argument if it is falsy or its second argument if the first argument is truthy; so normalized will be undefined if someString was undefined and so forth. That means that none of the inputs to the boolean expressions above are actually boolean values.

I know that a lot of programmers who are accustomed to strong type-checking cringe when seeing code like this. But note applying strong typing would likely require explicit checks for null or undefined values, which would clutter up the code. In JavaScript that is not needed.

I found a way that works for me. It is not 100% exact but it eliminates all strings that contain more than just the word I am looking for because I check for the string not containing individual spaces too. By the way you don't need these " ". jQuery knows you are looking for a string. Make sure you only have one space in the :contains( ) part otherwise it won't work.

<p>hello</p>
<p>hello world</p>
$('p:contains(hello):not(:contains( ))').css('font-weight', 'bold');

And yes I know it won't work if you have stuff like <p>helloworld</p>

This is bad style, but I'll assume you have a good reason for doing something similar.

<html>
<body>
    <input type="text" id="userInput">give me input</input>
    <button id="submitter">Submit</button>
    <div id="output"></div>
    <script>
        var didClickIt = false;
        document.getElementById("submitter").addEventListener("click",function(){
            // same as onclick, keeps the JS and HTML separate
            didClickIt = true;
        });

        setInterval(function(){
            // this is the closest you get to an infinite loop in JavaScript
            if( didClickIt ) {
                didClickIt = false;
                // document.write causes silly problems, do this instead (or better yet, use a library like jQuery to do this stuff for you)
                var o=document.getElementById("output"),v=document.getElementById("userInput").value;
                if(o.textContent!==undefined){
                    o.textContent=v;
                }else{
                    o.innerText=v;
                }
            }
        },500);
    </script>
</body>
</html>

You can use javascript's indexOf function.

var str1 = "ABCDEFGHIJKLMNOP";
var str2 = "DEFG";
if(str1.indexOf(str2) != -1){
   alert(str2 + " found");
}

This typically happens when you have an attribute of targetFramework="4.0" in the web.config but the App Pool is set to run ASP.NET 2.0. The targetFramework attribute is entirely unrecognized by ASP.NET 2.0 - so changing it to 2.0 won't have the desired effect.

Contact Support / Your Administrator and have the AppPool switched to 4.0.

You could also remove the attribute entirely, however if your site was coded with the 4.0 Framework, then I'm sure something else will cause an error as well.

Unrecognized attribute 'targetFramework'. Note that attribute names are case-sensitive

Three ways to pass model data to partial view (there may be more)

This is view page

Method One Populate at view

@{    
    PartialViewTestSOl.Models.CountryModel ctry1 = new PartialViewTestSOl.Models.CountryModel();
    ctry1.CountryName="India";
    ctry1.ID=1;    

    PartialViewTestSOl.Models.CountryModel ctry2 = new PartialViewTestSOl.Models.CountryModel();
    ctry2.CountryName="Africa";
    ctry2.ID=2;

    List<PartialViewTestSOl.Models.CountryModel> CountryList = new List<PartialViewTestSOl.Models.CountryModel>();
    CountryList.Add(ctry1);
    CountryList.Add(ctry2);    

}

@{
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",CountryList );
}

Method Two Pass Through ViewBag

@{
    var country = (List<PartialViewTestSOl.Models.CountryModel>)ViewBag.CountryList;
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",country );
}

Method Three pass through model

@{
    Html.RenderPartial("~/Views/PartialViewTest.cshtml",Model.country );
}

To install only from local you need 2 options:

• --find-links: where to look for dependencies. There is no need for the file:// prefix mentioned by others.
• --no-index: do not look in pypi indexes for missing dependencies (dependencies not installed and not in the --find-links path).

So you could run from any folder the following:

pip install --no-index --find-links /srv/pkg /path/to/mypackage-0.1.0.tar.gz

If your mypackage is setup properly, it will list all its dependencies, and if you used pip download to download the cascade of dependencies (ie dependencies of depencies etc), everything will work.

If you want to use the pypi index if it is accessible, but fallback to local wheels if not, you can remove --no-index and add --retries 0. You will see pip pause for a bit while it is try to check pypi for a missing dependency (one not installed) and when it finds it cannot reach it, will fall back to local. There does not seem to be a way to tell pip to "look for local ones first, then the index".

StringBuilder b = new StringBuilder();

Scanner s = new Scanner(System.in);
String n = s.nextLine();

for(int i = 0; i < n.length(); i++) {
    char c = n.charAt(i);

    if(Character.isLowerCase(c) == true) {
        b.append(String.valueOf(c).toUpperCase());
    }
    else {
        b.append(String.valueOf(c).toLowerCase());
    }
}

System.out.println(b);

There are also options available in the form of various libraries that can make this process very familiar to people that have used other MVVM frameworks.

https://developer.android.com/topic/libraries/data-binding/

Shows an example of an official library, that allows you to bind buttons like this:

<Button
    android:text="Start second activity"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:onClick="@{() -> presenter.showList()}"
/>

You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/

(very rough example)

#!/usr/bin/expect
set pass "mysecret"

spawn /usr/bin/passwd

expect "password: "
send "$pass"
expect "password: "
send "$pass"

Besides what other said, a common problem is to declare the types of the same function that is overloaded. Typical case is EventEmitter on() method which will accept multiple kind of listeners. Similar could happen When working with redux actions - and there you use the action type as literal to mark the overloading, In case of EventEmitters, you use the event name literal type:

interface MyEmitter extends EventEmitter {
  on(name:'click', l: ClickListener):void
  on(name:'move', l: MoveListener):void
  on(name:'die', l: DieListener):void
  //and a generic one
  on(name:string, l:(...a:any[])=>any):void
}

type ClickListener = (e:ClickEvent)=>void
type MoveListener = (e:MoveEvent)=>void
... etc

// will type check the correct listener when writing something like:
myEmitter.on('click', e=>...<--- autocompletion

The parameters of isset() should be separated by a comma sign (,) and not a dot sign (.). Your current code concatenates the variables into a single parameter, instead of passing them as separate parameters.

So the original code evaluates the variables as a unified string value:

isset($_POST['search_term'] . $_POST['postcode']) // Incorrect

While the correct form evaluates them separately as variables:

isset($_POST['search_term'], $_POST['postcode']) // Correct

You can try this

$scope.$watch('tags ',function(){

    $scope.tags = $filter('lowercase')($scope.tags);

});

Try this

import pandas as pd
data=pd.read_csv('C:/Users/Downloads/winequality-red.csv')

Replace the file target location, with where your data set is found, refer this url https://medium.com/@kanchanardj/jargon-in-python-used-in-data-science-to-laymans-language-part-one-12ddfd31592f

A SELECT INTO statement creates the table for you. There is no need for the CREATE TABLE statement before hand.

What is happening is that you create #ivmy_cash_temp1 in your CREATE statement, then the DB tries to create it for you when you do a SELECT INTO. This causes an error as it is trying to create a table that you have already created.

Either eliminate the CREATE TABLE statement or alter your query that fills it to use INSERT INTO SELECT format.

If you need a unique ID added to your new row then it's best to use SELECT INTO... since IDENTITY() only works with this syntax.

try this:

struct Pos{
    int x;
    int y;

    inline Pos& operator=(const Pos& other){
        x=other.x;
        y=other.y;
        return *this;
    }

    inline Pos operator+(const Pos& other) const {
        Pos res {x+other.x,y+other.y};
        return res;
    }

    const inline bool operator==(const Pos& other) const {
        return (x==other.x and y == other.y);
    }
 };  

In my thinking a user stops writing when he doesn't keep focus on that input. For this you have a function called "blur" which does stuff like

Without a frame this works for me:

JTextField tf = new JTextField(20);
tf.addKeyListener(new KeyAdapter() {

  public void keyPressed(KeyEvent e) {
    if (e.getKeyCode()==KeyEvent.VK_ENTER){
       SwingUtilities.getWindowAncestor(e.getComponent()).dispose();
    }
  }
});
String[] options = {"Ok", "Cancel"};
int result = JOptionPane.showOptionDialog(
    null, tf, "Enter your message", 
    JOptionPane.OK_CANCEL_OPTION,
    JOptionPane.QUESTION_MESSAGE,
    null,
    options,0);

message = tf.getText();

you can not do it in this way

Use the following instead

typedef struct
{
   int id;
   char* name;
}employee;

employee emp = {
.id = 0, 
.name = "none"
};

You can use macro to define and initialize your instances. this will make easiier to you each time you want to define new instance and initialize it.

typedef struct
{
   int id;
   char* name;
}employee;

#define INIT_EMPLOYEE(X) employee X = {.id = 0, .name ="none"}

and in your code when you need to define new instance with employee type, you just call this macro like:

INIT_EMPLOYEE(emp);

As already mentioned, tern.js is a new and promising project with plugins for Sublime Text, Vim and Emacs. I´ve been using TernJS for Sublime for a while and the suggestions I get are way better than the standard ones:

Tern scans all .js files in your project. You can get support for DOM, nodejs, jQuery, and more by adding "libs" in your .sublime-project file:

"ternjs": {
    "exclude": ["wordpress/**", "node_modules/**"],
    "libs": ["browser", "jquery"],
    "plugins": {
        "requirejs": {
            "baseURL": "./js"
        }
    }
}

You can't free types that aren't dynamically allocated. Although arrays are syntactically similar (int* x = malloc(sizeof(int) * 4) can be used in the same way that int x[4] is), calling free(firstName) would likely cause an error for the latter.

For example, take this code:

int x;
free(&x);

free() is a function which takes in a pointer. &x is a pointer. This code may compile, even though it simply won't work.

If we pretend that all memory is allocated in the same way, x is "allocated" at the definition, "freed" at the second line, and then "freed" again after the end of the scope. You can't free the same resource twice; it'll give you an error.

This isn't even mentioning the fact that for certain reasons, you may be unable to free the memory at x without closing the program.

tl;dr: Just free the struct and you'll be fine. Don't call free on arrays; only call it on dynamically allocated memory.

Update: ASP.NET Core does not have a SynchronizationContext. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false) or not.

For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.

Original post (for non-Core ASP.NET):

This video by the ASP.NET team has the best information on using async on ASP.NET.

I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.

This is true with UI applications, where there is only one UI thread that you have to "sync" back to.

In ASP.NET, the situation is a bit more complex. When an async method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false), then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.

So ConfigureAwait(false) does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false) could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.

Actually, just doing an await can do that. Once your async method hits an await, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.

The only difference ConfigureAwait makes in ASP.NET is whether that thread enters the request context when resuming the method.

I have more background information in my MSDN article on SynchronizationContext and my async intro blog post.

How about

user r = {"",{}};

or

user r = {"",{'\0'}};

or

user r = {"",std::vector<unsigned char>()};

or

user r;

Technically, the char* is not an array, but a pointer to a char.

Similarly, char** is a pointer to a char*. Making it a pointer to a pointer to a char.

C and C++ both define arrays behind-the-scenes as pointer types, so yes, this structure, in all likelihood, is array of arrays of chars, or an array of strings.

I use to throw an exception in the base class.

protected abstractMethod() {
    throw new Error("abstractMethod not implemented");
}

Then you have to implement in the sub-class. The cons is that there is no build error, but run-time. The pros is that you can call this method from the super class, assuming that it will work :)

Here's simple solution for those who want a quick filter against an object:

<select>
  <option ng-repeat="card in deck.Cards | filter: {Type: 'Face'}">{{card.Name}}</option>
</select>

The array filter lets you mimic the object you are trying to filter. In the above case, the following classes would work just fine:

var card = function(name, type) {
  var _name = name;
  var _type = type;

  return {
    Name: _name,
    Type: _type
  };
};

And where the deck might look like:

var deck = function() {
  var _cards = [new card('Jack', 'Face'),
                new card('7', 'Numeral')];

  return {
    Cards: _cards
  };
};

And if you want to filter multiple properties of the object just separate field names by a comma:

<select>
  <option ng-repeat="card in deck.Cards | filter: {Type: 'Face', Name: 'Jack'}">{{card.Name}}</option>
</select>

EDIT: Here's a working plnkr that provides an example of single and multiple property filters:

use Request.Form to get the Data

Controller:

    [HttpPost]
    public ActionResult Index(int? id)
    {
        string jsonData= Request.Form[0]; // The data from the POST
    }

I write this to try

View:

<input type="button" value="post" id="btnPost" />

<script type="text/javascript">
    $(function () {
        var test = {
            number: 456,
            name: "Ryu"
        }
        $("#btnPost").click(function () {
            $.post('@Url.Action("Index", "Home")', JSON.stringify(test));
        });
    });
</script>

and write Request.Form[0] or Request.Params[0] in controller can get the data.

I don't write <form> tag in view.

When you use Vector *one you are merely creating a pointer to the structure but there is no memory allocated to it.

Simply use one = (Vector *)malloc(sizeof(Vector)); to declare memory and instantiate it.

TypeScript isn't giving you a gun to shoot yourself in the foot with.

The iterator variable is a string because it is a string, full stop. Observe:

var obj = {};
obj['0'] = 'quote zero quote';
obj[0.0] = 'zero point zero';
obj['[object Object]'] = 'literal string "[object Object]"';
obj[<any>obj] = 'this obj'
obj[<any>undefined] = 'undefined';
obj[<any>"undefined"] = 'the literal string "undefined"';

for(var key in obj) {
    console.log('Type: ' + typeof key);
    console.log(key + ' => ' + obj[key]);
}

How many key/value pairs are in obj now? 6, more or less? No, 3, and all of the keys are strings:

Type: string
0 => zero point zero
Type: string
[object Object] => this obj; 
Type: string
undefined => the literal string "undefined" 

You can get the same error in Asp.net MVC5 if you have a class name and a folder with a matching name Example : If you have class lands where when you want to see view/lands/index.cshtml file, if you also have a folder with name 'lands' you get the error as it first try the lands folder

You could try either of these. They are not giving me errors.

It is also the suggested method from typescript for array declaration.

By using the Array<Thing> it is making use of the generics in typescript. It is similar to asking for a List<T> in c# code.

// Declare with default value
private _possessions: Array<Thing> = new Array<Thing>();
// or
private _possessions: Array<Thing> = [];
// or -> prefered by ts-lint
private _possessions: Thing[] = [];

or

// declare
private _possessions: Array<Thing>;
// or -> preferd by ts-lint
private _possessions: Thing[];

constructor(){
    //assign
    this._possessions = new Array<Thing>();
    //or
    this._possessions = [];
}

what I'd call a hack, but given that you're only processing hour values, you can do

 hour=08
 echo $(( ${hour#0} +1 ))
 9
 hour=10 
 echo $(( ${hour#0} +1))
 11

with little risk.

IHTH.

If you want to use Arrays, it's pretty simple.

logs = gson.fromJson(br, JsonLog[].class); // line 6

Provide the JsonLog as an array JsonLog[].class

     foreach (DataRow row in dt.Rows) 
     {
        foreach (DataColumn col in dt.Columns)
           Console.WriteLine(row[col]);
     }

var i2 = JsonConvert.DeserializeObject(obj["id"].ToString(), type);

throws a parsing exception due to missing quotes around the first argument (I think). I got it to work by adding the quotes:

var i2 = JsonConvert.DeserializeObject("\"" + obj["id"].ToString() + "\"", type);

Try setting the path this way:

Before answering, I would like to give you some data from Wiki

Data structure alignment is the way data is arranged and accessed in computer memory. It consists of two separate but related issues: data alignment and data structure padding.

When a modern computer reads from or writes to a memory address, it will do this in word sized chunks (e.g. 4 byte chunks on a 32-bit system). Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory.

To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

gcc provides functionality to disable structure padding. i.e to avoid these meaningless bytes in some cases. Consider the following structure:

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}sSampleStruct;

sizeof(sSampleStruct) will be 12 rather than 8. Because of structure padding. By default, In X86, structures will be padded to 4-byte alignment:

typedef struct
{
     char Data1;
     //3-Bytes Added here.
     int Data2;
     unsigned short Data3;
     char Data4;
     //1-byte Added here.

}sSampleStruct;

We can use __attribute__((packed, aligned(X))) to insist particular(X) sized padding. X should be powers of two. Refer here

typedef struct
{
     char Data1;
     int Data2;
     unsigned short Data3;
     char Data4;

}__attribute__((packed, aligned(1))) sSampleStruct;  

so the above specified gcc attribute does not allow the structure padding. so the size will be 8 bytes.

If you wish to do the same for all the structures, simply we can push the alignment value to stack using #pragma

#pragma pack(push, 1)

//Structure 1
......

//Structure 2
......

#pragma pack(pop)

I fixed this issue by removing the credential section from the config of specific project:

• Just typed: git config -e
• Inside the editor I removed the whole section [credential] helper = cache.

This removed the annoying message :

git: 'credential-cache' is not a git command. See 'git --help'.

In addition to the other answers here, here's how you can do it on Ubuntu (14.04):

sudo apt-get install libmysql-java

this will download mysql-connector-java-5.x.x.jar to /usr/share/java/, which i believe also automatically creates a symlink named mysql-connector-java.jar.

Then, create a symlink in /your/path/to/data-integration/lib/:

ln -s /usr/share/java/mysql-connector-java.jar /your/path/to/data-integration/lib/mysql-connector-java.jar

Python is strongly, dynamically typed.

• Strong typing means that the type of a value doesn't change in unexpected ways. A string containing only digits doesn't magically become a number, as may happen in Perl. Every change of type requires an explicit conversion.
• Dynamic typing means that runtime objects (values) have a type, as opposed to static typing where variables have a type.

As for your example

bob = 1
bob = "bob"

This works because the variable does not have a type; it can name any object. After bob=1, you'll find that type(bob) returns int, but after bob="bob", it returns str. (Note that type is a regular function, so it evaluates its argument, then returns the type of the value.)

Contrast this with older dialects of C, which were weakly, statically typed, so that pointers and integers were pretty much interchangeable. (Modern ISO C requires conversions in many cases, but my compiler is still lenient about this by default.)

I must add that the strong vs. weak typing is more of a continuum than a boolean choice. C++ has stronger typing than C (more conversions required), but the type system can be subverted by using pointer casts.

The strength of the type system in a dynamic language such as Python is really determined by how its primitives and library functions respond to different types. E.g., + is overloaded so that it works on two numbers or two strings, but not a string and an number. This is a design choice made when + was implemented, but not really a necessity following from the language's semantics. In fact, when you overload + on a custom type, you can make it implicitly convert anything to a number:

def to_number(x):
    """Try to convert function argument to float-type object."""
    try: 
        return float(x) 
    except (TypeError, ValueError): 
        return 0 

class Foo:
    def __init__(self, number): 
        self.number = number

    def __add__(self, other):
        return self.number + to_number(other)

Instance of class Foo can be added to other objects:

>>> a = Foo(42)
>>> a + "1"
43.0
>>> a + Foo
42
>>> a + 1
43.0
>>> a + None
42

Observe that even though strongly typed Python is completely fine with adding objects of type int and float and returns an object of type float (e.g., int(42) + float(1) returns 43.0). On the other hand, due to the mismatch between types Haskell would complain if one tries the following (42 :: Integer) + (1 :: Float). This makes Haskell a strictly typed language, where types are entirely disjoint and only a controlled form of overloading is possible via type classes.

We can also get the version by looking at the version of the hive-metastore jar file.

For example:

$ ls /usr/lib/hive/lib/ | grep metastore
hive-metastore-0.13.1.jar

Upgrade the version of node without installing any package, not even nvm itself:

sudo npx n stable

Explanations:
This approach is similar to Johan Dettmar's answer. The only difference is here the package n is not installed glabally in the local machine.

The first is easiest(involves less typing), and it is guaranteed to work, all members will be set to 0^{[Ref 1]}.
The second is more readable.

The choice depends on user preference or the one which your coding standard mandates.

^{[Ref 1]} Reference C99 Standard 6.7.8.21:

If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

There's a lot of typedef going on here. Personally I'm against "hiding the asterisk", i.e. typedef:ing pointer types into something that doesn't look like a pointer. In C, pointers are quite important and really affect the code, there's a lot of difference between foo and foo *.

Many of the answers are also confused about this, I think.

Your allocation of an array of Chess values, which are pointers to values of type chess (again, a very confusing nomenclature that I really can't recommend) should be like this:

Chess *array = malloc(n * sizeof *array);

Then, you need to initialize the actual instances, by looping:

for(i = 0; i < n; ++i)
  array[i] = NULL;

This assumes you don't want to allocate any memory for the instances, you just want an array of pointers with all pointers initially pointing at nothing.

If you wanted to allocate space, the simplest form would be:

for(i = 0; i < n; ++i)
  array[i] = malloc(sizeof *array[i]);

See how the sizeof usage is 100% consistent, and never starts to mention explicit types. Use the type information inherent in your variables, and let the compiler worry about which type is which. Don't repeat yourself.

Of course, the above does a needlessly large amount of calls to malloc(); depending on usage patterns it might be possible to do all of the above with just one call to malloc(), after computing the total size needed. Then you'd still need to go through and initialize the array[i] pointers to point into the large block, of course.

They are largely the same, except that:

The alias declaration is compatible with templates, whereas the C style typedef is not.

It looks like you may be confused as to when commands are run. In your example, you are calling the get method before the GUI has a chance to be displayed on the screen (which happens after you call mainloop.

Try adding a button that calls the get method. This is much easier if you write your application as a class. For example:

import tkinter as tk

class SampleApp(tk.Tk):
    def __init__(self):
        tk.Tk.__init__(self)
        self.entry = tk.Entry(self)
        self.button = tk.Button(self, text="Get", command=self.on_button)
        self.button.pack()
        self.entry.pack()

    def on_button(self):
        print(self.entry.get())

app = SampleApp()
app.mainloop()

Run the program, type into the entry widget, then click on the button.

The main problem is that operator [] is used to insert and read a value into and from the map, so it cannot be const. If the key does not exist, it will create a new entry with a default value in it, incrementing the size of the map, that will contain a new key with an empty string ,in this particular case, as a value if the key does not exist yet. You should avoid operator[] when reading from a map and use, as was mention before, "map.at(key)" to ensure bound checking. This is one of the most common mistakes people often do with maps. You should use "insert" and "at" unless your code is aware of this fact. Check this talk about common bugs Curiously Recurring C++ Bugs at Facebook

While Richard's is what you want if you do want to go with a typedef, I'd suggest that it's probably not a particularly good idea in this instance, as you lose sight of it being a pointer, while not gaining anything.

If you were treating it a a counted string, or something with additional functionality, that might be different, but I'd really recommend that in this instance, you just get familiar with the 'standard' C string implementation being a 'char *'...

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{
    typedef int VLA[m][m];     // valid: block scope typedef VLA
    struct tag {
        int (*y)[n];           // invalid: y not ordinary identifier
        int z[n];              // invalid: z not ordinary identifier
    };
    int D[m];                  // valid: auto VLA
    static int E[m];           // invalid: static block scope VLA
    extern int F[m];           // invalid: F has linkage and is VLA
    int (*s)[m];               // valid: auto pointer to VLA
    extern int (*r)[m];        // invalid: r has linkage and points to VLA
    static int (*q)[m] = &B;   // valid: q is a static block pointer to VLA
}

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

If you're using WordPress, there is now a filter hook to resolve this:

remove_filter('template_redirect', 'redirect_canonical'); 

(Put this in your theme's functions.php)

This tells WordPress to not redirect index.php back to the root page, but to sit where it is. That way, index.html can be assigned to be the default page in .htaccess and can work alongside index.php.

});

This works for me.

        List<Part> cloneParts = objectMapper.readValue(jsonStr, new TypeReference<ArrayList<Part>>() {});
    } catch (Exception e) {
        //fail("failed.");
        e.printStackTrace();

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

I created these examples.

    var val = '^(?=.*\\b' + $.trim($(this).val()).split(/\s+/).join('\\b)(?=.*\\b') + ').*$',
        reg = RegExp(val, 'i'),
        text;

    $rows.show().filter(function() {
        text = $(this).text().replace(/\s+/g, ' ');
        return !reg.test(text);
    }).hide();
});

Debounce

When you implement table filtering with search over multiple rows and columns it is very important that you consider performance and search speed/optimisation. Simply saying you should not run search function on every single keystroke, it's not necessary. To prevent filtering to run too often you should debounce it. Above code example will become:

$('#search').keyup(debounce(function() {
    var val = $.trim($(this).val()).replace(/ +/g, ' ').toLowerCase();
    // etc...
}, 300));

You can pick any debounce implementation, for example from Lodash _.debounce, or you can use something very simple like I use in next demos (debounce from here): http://jsfiddle.net/7BUmG/6230/ and http://jsfiddle.net/7BUmG/6231/.

As the "GNU C Library Reference Manual" says

off_t
    This is a signed integer type used to represent file sizes. 
    In the GNU C Library, this type is no narrower than int.
    If the source is compiled with _FILE_OFFSET_BITS == 64 this 
    type is transparently replaced by off64_t.

and

off64_t
    This type is used similar to off_t. The difference is that 
    even on 32 bit machines, where the off_t type would have 32 bits,
    off64_t has 64 bits and so is able to address files up to 2^63 bytes
    in length. When compiling with _FILE_OFFSET_BITS == 64 this type 
    is available under the name off_t.

Thus if you want reliable way of representing file size between client and server, you can:

1. Use off64_t type and stat64() function accordingly (as it fills structure stat64, which contains off64_t type itself). Type off64_t guaranties the same size on 32 and 64 bit machines.
2. As was mentioned before compile your code with -D_FILE_OFFSET_BITS == 64 and use usual off_t and stat().
3. Convert off_t to type int64_t with fixed size (C99 standard). Note: (my book 'C in a Nutshell' says that it is C99 standard, but optional in implementation). The newest C11 standard says:

7.20.1.1 Exact-width integer types

    1 The typedef name intN_t designates a signed integer type with width N ,
    no padding bits, and a two’s complement representation. Thus, int8_t 
    denotes such a signed integer type with a width of exactly 8 bits.
    without mentioning.

And about implementation:

7.20 Integer types <stdint.h>

    ... An implementation shall provide those types described as ‘‘required’’,
    but need not provide any of the others (described as ‘‘optional’’).
    ...
    The following types are required:
    int_least8_t  uint_least8_t
    int_least16_t uint_least16_t
    int_least32_t uint_least32_t
    int_least64_t uint_least64_t
    All other types of this form are optional.

Thus, in general, C standard can't guarantee types with fixed sizes. But most compilers (including gcc) support this feature.

Remove/Replace all special chars in Jquery :

If

str = My name is "Ghanshyam" and from "java" background

and want to remove all special chars (") then use this

str=str.replace(/"/g,' ')

result:

My name is Ghanshyam and from java background

Where g means Global

For future people struggling with a similar problem, the situation is that the compiler simply cannot find the type you are using (even if your Intelisense can find it).

This can be caused in many ways:

• You forgot to #include the header that defines it.
• Your inclusion guards (#ifndef BLAH_H) are defective (your #ifndef BLAH_H doesn't match your #define BALH_H due to a typo or copy+paste mistake).
• Your inclusion guards are accidentally used twice (two separate files both using #define MYHEADER_H, even if they are in separate directories)
• You forgot that you are using a template (eg. new Vector() should be new Vector<int>())
• The compiler is thinking you meant one scope when really you meant another (For example, if you have NamespaceA::NamespaceB, AND a <global scope>::NamespaceB, if you are already within NamespaceA, it'll look in NamespaceA::NamespaceB and not bother checking <global scope>::NamespaceB) unless you explicitly access it.
• You have a name clash (two entities with the same name, such as a class and an enum member).

To explicitly access something in the global namespace, prefix it with ::, as if the global namespace is a namespace with no name (e.g. ::MyType or ::MyNamespace::MyType).

Since placeholder disappear on input, you can use:

input:placeholder-shown{
    //rules for not empty input
}

Basically this error comes when you have not specified a password, it means that you have an incorrect password listed in some option file.

Read this DOC on understanding how to assign and manage Passwords to accounts.

Also , Check if the permission on the folder /var/lib/mysql/mysql is 711 or not.

I also faced the same issue but in VS2013.

I did the below way to fix, It was worked fine.

1. Close all the opened Visual studio instance.

2. Then, go to "Developer command prompt" from visual studio tools,

3. Type it as devenv.exe /resetuserdata

4. Restart the machine, Open the Visual studio then It will ask you to choose the development settings from initial onwards, thereafter open any solution/project. You'll be amazed.

Hope, it might helps you :)

Default

The default Gson implementation of Map serialization uses toString() on the key:

Gson gson = new GsonBuilder()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will give:

{
  "java.awt.Point[x\u003d1,y\u003d2]": "a",
  "java.awt.Point[x\u003d3,y\u003d4]": "b"
}

Using enableComplexMapKeySerialization

If you want the Map Key to be serialized according to default Gson rules you can use enableComplexMapKeySerialization. This will return an array of arrays of key-value pairs:

Gson gson = new GsonBuilder().enableComplexMapKeySerialization()
        .setPrettyPrinting().create();
Map<Point, String> original = new HashMap<>();
original.put(new Point(1, 2), "a");
original.put(new Point(3, 4), "b");
System.out.println(gson.toJson(original));

Will return:

[
  [
    {
      "x": 1,
      "y": 2
    },
    "a"
  ],
  [
    {
      "x": 3,
      "y": 4
    },
    "b"
  ]
]

Strongly typed enums aiming to solve multiple problems and not only scoping problem as you mentioned in your question:

1. Provide type safety, thus eliminating implicit conversion to integer by integral promotion.
2. Specify underlying types.
3. Provide strong scoping.

Thus, it is impossible to implicitly convert a strongly typed enum to integers, or even its underlying type - that's the idea. So you have to use static_cast to make conversion explicit.

If your only problem is scoping and you really want to have implicit promotion to integers, then you better off using not strongly typed enum with the scope of the structure it is declared in.

I found the answer in ubuntuforums (ubuntuforums), you can just add this to your gcc '$(python-config --includes)'

gcc $(python-config --includes) urfile.c

Yes you have to if you take the unique_ptr by value in the constructor. Explicity is a nice thing. Since unique_ptr is uncopyable (private copy ctor), what you wrote should give you a compiler error.

use
if in vim:

:s/{\|}/"/g

will replace { and } on " so {lol} becomes "lol"

Edit (2017-10-12):

@MechaLynx and @Kevin-Weber note that unescape() is deprecated from non-browser environments and does not exist in TypeScript. decodeURIComponent is a drop-in replacement. For broader compatibility, use the below instead:

decodeURIComponent(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'

Original answer:

unescape(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'

You can offload all the work to JSON.parse

Try to not use the -W parameter and leave the password in blank. Sometimes the user is created with no-password.

If that doesn't work reset the password. There are several ways to do it, but this works on many systems:

$ su root
$ su postgres
$ psql -h localhost
> ALTER USER postgres with password 'YourNewPassword';

To use the fastboot command you first need to put your device in fastboot mode:

$ adb reboot bootloader

Once the device is in fastboot mode, you can boot it with your own kernel, for example:

$ fastboot boot myboot.img

The above will only boot your kernel once and the old kernel will be used again when you reboot the device. To replace the kernel on the device, you will need to flash it to the device:

$ fastboot flash boot myboot.img

Hope that helps.

<input type="text" autocomplete="off" />

may be you can specify where the buildfile is located and then invoke desired action.

Eg: ant -file {BuildfileLocation/build.xml} -v

Just go to the properties of your cmd.exe shortcut and change the 'start in' by adding the file name where you put all your '.txt' files.I had same problems and i put the whole file mane as 'D:\photon' in the 'start in' of the properties and it worked.Remember you have to put all your files in that folder otherwise you have to create many shortcuts for each data files.Sorry for late reply

Well it seems that you are missing a reference to some library. I had the similar error solved it by adding a reference to the #pragma comment(lib, "windowscodecs.lib")

You could subscribe for the onkeypress event:

<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />

and then define the isNumber function:

function isNumber(evt) {
    evt = (evt) ? evt : window.event;
    var charCode = (evt.which) ? evt.which : evt.keyCode;
    if (charCode > 31 && (charCode < 48 || charCode > 57)) {
        return false;
    }
    return true;
}

You can see it in action here.

I seem to be a bit late to the party and much more of a beginner than any expertise; BUT this worked for me:

window.onbeforeunload = function() {
      return false;
};

I placed this as an inline script immediately after my Head and Meta elements, like this:

<script>
  window.onbeforeunload = function() {
     return false;
  }
</script>

This page seems to me to be highly relevant to the originator's requirement (especially the sections headed window.onunload and window.onbeforeunload): https://javascript.info/onload-ondomcontentloaded

Hoping this helps.

I struggled a lot to resolve it Nothing seemed to work for me.

The steps I followed are mentioned here.

1 - Go to your App settings.

2 - Click on Add domain.

3 - A dialog will open & will ask you to enter the desired domain. (Please add it starting with www for instance - www.abcd.com )

4 - One added click on Next to move to the next dialog.

5 - After adding the domain you will get the DNS target, Now you need to navigate to GoDaddy and follow the following steps.

6 - Navigate to https://dcc.godaddy.com/domains & click on your domain.

7 - Once clicked you will navigate to https://dcc.godaddy.com/control/yourdomain/settings

8 - Scroll down to the bottom you will see Manage DNS.

9 - It will navigate you to DNS settings then add the entry similar to mentioned below and delete all other CNAME records. Here the value of points is your DNS target that you got in the 4th Step.

10 - Then after some time your site should be mapped to the Heroku app URL.

Jason,

This is how it works.

Localnamespace - java:comp/env is a local name space used by the application. The name that you use in it jdbc/db is just an alias. It does not refer to a physical resource.

During deployment this alias should be mapped to a physical resource (in your case a data source) that is defined on the WAS/WPS run time.

This is actually stored in ejb-bnd.xmi files. In the latest versions the XMIs are replaced with XML files. These files are referred to as the Binding files.

HTH Manglu

You should use keyPressed if you want an immediate effect, and keyReleased if you want the effect after you release the key. You cannot use keyTyped because F5 is not a character. keyTyped is activated only when an character is pressed.

The only solution for such warnings is to include stdlib.h in the program.

Here in swift version for same.

textField.addTarget(self, action: "textFieldDidChange:", forControlEvents: UIControlEvents.EditingChanged)

func textFieldDidChange(textField: UITextField) {

}

Thanks

Let's say you have an arrayBuffer binaryStr:

let text = String.fromCharCode.apply(null, new Uint8Array(binaryStr));

and then you assign the text to the state.

First, you can use sql command show global variables like 'innodb_buffer%'; to check the buffer size.

Solution is find your my.cnf file and add,

[mysqld]_x000D_
innodb_buffer_pool_size=1G # depends on your data and machine

DO NOT forget to add [mysqld], otherwise, it won't work.

In my case, ubuntu 16.04, my.cnf is located under the folder /etc/mysql/.

Actually it's quite different. DOUBLE causes rounding issues. And if you do something like 0.1 + 0.2 it gives you something like 0.30000000000000004. I personally would not trust financial data that uses floating point math. The impact may be small, but who knows. I would rather have what I know is reliable data than data that were approximated, especially when you are dealing with money values.

Have you installed Xcode and the developer tools? I think make, along with gcc and friends, is installed with that and not before. Xcode 4.1 for Lion is free.

If the number is stored in a string (which it would be if typed by a user), you can use atoi() to convert it to an integer.

An integer can be assigned directly to a character. A character is different mostly just because how it is interpreted and used.

char c = atoi("61");

    // acos(0.0) will return value of pi/2, inverse of cos(0) is pi/2 
    double pi = 2 * acos(0.0);
    int n; // upto 6 digit
    scanf("%d",&n); //precision with which you want the value of pi
    printf("%.*lf\n",n,pi); // * will get replaced by n which is the required precision

Since style A is not allowed in C++ and you don't want style B then how about using style BX:

FooBar fb = { /*.foo=*/ 12, /*.bar=*/ 3.4 };  // :)

At least help at some extent.

You can skip the var declaration and the stringify. Otherwise, that will work just fine.

$.ajax({
    url: '/home/check',
    type: 'POST',
    data: {
        Address1: "423 Judy Road",
        Address2: "1001",
        City: "New York",
        State: "NY",
        ZipCode: "10301",
        Country: "USA"
    },
    contentType: 'application/json; charset=utf-8',
    success: function (data) {
        alert(data.success);
    },
    error: function () {
        alert("error");
    }
});

I suspect the problem is because the json represents an object with the list of users as a property. Try deserializing to something like:

public class UsersResponse
{
    public List<User> Data { get; set; }
}

To know the format string used by Excel without having to guess it: create an excel file, write a date in cell A1 and format it as you want. Then run the following lines:

FileInputStream fileIn = new FileInputStream("test.xlsx");
Workbook workbook = WorkbookFactory.create(fileIn);
CellStyle cellStyle = workbook.getSheetAt(0).getRow(0).getCell(0).getCellStyle();
String styleString = cellStyle.getDataFormatString();
System.out.println(styleString);

Then copy-paste the resulting string, remove the backslashes (for example d/m/yy\ h\.mm;@ becomes d/m/yy h.mm;@) and use it in the http://poi.apache.org/spreadsheet/quick-guide.html#CreateDateCells code:

CellStyle cellStyle = wb.createCellStyle();
CreationHelper createHelper = wb.getCreationHelper();
cellStyle.setDataFormat(createHelper.createDataFormat().getFormat("d/m/yy h.mm;@"));
cell = row.createCell(1);
cell.setCellValue(new Date());
cell.setCellStyle(cellStyle);

in flask using flask.ext.script, you can do it like this:

python manage.py runserver -h 127.0.0.1 -p 8000

Yes, the 3rd template parameter on map specifies the comparator, which is a binary predicate. Example:

struct ByLength : public std::binary_function<string, string, bool>
{
    bool operator()(const string& lhs, const string& rhs) const
    {
        return lhs.length() < rhs.length();
    }
};

int main()
{
    typedef map<string, string, ByLength> lenmap;
    lenmap mymap;

    mymap["one"] = "one";
    mymap["a"] = "a";
    mymap["fewbahr"] = "foobar";

    for( lenmap::const_iterator it = mymap.begin(), end = mymap.end(); it != end; ++it )
        cout << it->first << "\n";
}

How are you doing the compiling and linking? You'll need to specify both files, something like:

gcc testpoint.c point.c

...so that it knows to link the functions from both together. With the code as it's written right now, however, you'll then run into the opposite problem: multiple definitions of main. You'll need/want to eliminate one (undoubtedly the one in point.c).

In a larger program, you typically compile and link separately to avoid re-compiling anything that hasn't changed. You normally specify what needs to be done via a makefile, and use make to do the work. In this case you'd have something like this:

OBJS=testpoint.o point.o

testpoint.exe: $(OBJS)
    gcc $(OJBS)

The first is just a macro for the names of the object files. You get it expanded with $(OBJS). The second is a rule to tell make 1) that the executable depends on the object files, and 2) telling it how to create the executable when/if it's out of date compared to an object file.

Most versions of make (including the one in MinGW I'm pretty sure) have a built-in "implicit rule" to tell them how to create an object file from a C source file. It normally looks roughly like this:

.c.o:
    $(CC) -c $(CFLAGS) $<

This assumes the name of the C compiler is in a macro named CC (implicitly defined like CC=gcc) and allows you to specify any flags you care about in a macro named CFLAGS (e.g., CFLAGS=-O3 to turn on optimization) and $< is a special macro that expands to the name of the source file.

You typically store this in a file named Makefile, and to build your program, you just type make at the command line. It implicitly looks for a file named Makefile, and runs whatever rules it contains.

The good point of this is that make automatically looks at the timestamps on the files, so it will only re-compile the files that have changed since the last time you compiled them (i.e., files where the ".c" file has a more recent time-stamp than the matching ".o" file).

Also note that 1) there are lots of variations in how to use make when it comes to large projects, and 2) there are also lots of alternatives to make. I've only hit on the bare minimum of high points here.

It's possible that you're not fetching the Joined Set. Be sure to include the set in your HQL:

public List<Node> getAll() {
    Session session = sessionFactory.getCurrentSession();
    Query query = session.createQuery("FROM Node as n LEFT JOIN FETCH n.nodeValues LEFT JOIN FETCH n.nodeStats");
    return  query.list();
}

Where your class has 2 sets like:

public class Node implements Serializable {

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeValue> nodeValues;

@OneToMany(fetch=FetchType.LAZY)
private Set<NodeStat> nodeStats;

}

Don't pass db models directly to your views. You're lucky enough to be using MVC, so encapsulate using view models.

Create a view model class like this:

public class EmployeeAddViewModel
{
    public Employee employee { get; set; }
    public Dictionary<int, string> staffTypes { get; set; }
    // really? a 1-to-many for genders
    public Dictionary<int, string> genderTypes { get; set; }

    public EmployeeAddViewModel() { }
    public EmployeeAddViewModel(int id)
    {
        employee = someEntityContext.Employees
            .Where(e => e.ID == id).SingleOrDefault();

        // instantiate your dictionaries

        foreach(var staffType in someEntityContext.StaffTypes)
        {
            staffTypes.Add(staffType.ID, staffType.Type);
        }

        // repeat similar loop for gender types
    }
}

Controller:

[HttpGet]
public ActionResult Add()
{
    return View(new EmployeeAddViewModel());
}

[HttpPost]
public ActionResult Add(EmployeeAddViewModel vm)
{
    if(ModelState.IsValid)
    {
        Employee.Add(vm.Employee);
        return View("Index"); // or wherever you go after successful add
    }

    return View(vm);
}

Then, finally in your view (which you can use Visual Studio to scaffold it first), change the inherited type to ShadowVenue.Models.EmployeeAddViewModel. Also, where the drop down lists go, use:

@Html.DropDownListFor(model => model.employee.staffTypeID,
    new SelectList(model.staffTypes, "ID", "Type"))

and similarly for the gender dropdown

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(model.genderTypes, "ID", "Gender"))

Update per comments

For gender, you could also do this if you can be without the genderTypes in the above suggested view model (though, on second thought, maybe I'd generate this server side in the view model as IEnumerable). So, in place of new SelectList... below, you would use your IEnumerable.

@Html.DropDownListFor(model => model.employee.genderID,
    new SelectList(new SelectList()
    {
        new { ID = 1, Gender = "Male" },
        new { ID = 2, Gender = "Female" }
    }, "ID", "Gender"))

Finally, another option is a Lookup table. Basically, you keep key-value pairs associated with a Lookup type. One example of a type may be gender, while another may be State, etc. I like to structure mine like this:

ID | LookupType | LookupKey | LookupValue | LookupDescription | Active
1  | Gender     | 1         | Male        | male gender       | 1
2  | State      | 50        | Hawaii      | 50th state        | 1
3  | Gender     | 2         | Female      | female gender     | 1
4  | State      | 49        | Alaska      | 49th state        | 1
5  | OrderType  | 1         | Web         | online order      | 1

I like to use these tables when a set of data doesn't change very often, but still needs to be enumerated from time to time.

Hope this helps!

var array=[];

array.push(array);  //insert the array value using push methods.

for (var i = 0; i < array.length; i++) {    
    nameList += "" + array[i] + "";          //display the array value.                                                             
}

$("id/class").html(array.length);   //find the array length.

I know this question has been answered 3 years ago, but this may be what your were looking for.

Google has released a couple of weeks ago a library allowing easy and flexible dynamic object allocations. Here it is: http://google-opensource.blogspot.fr/2014/01/introducing-infact-library.html

Personally, I would go for something simple and use an operator to do so.

Considering the following enum:

enum WeekDay { MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY, SUNDAY };

We can create an operator to output the result in an std::ostream.

std::ostream &operator<<(std::ostream &stream, const WeekDay day) {
  switch (day) {
    case MONDAY:
      stream << "Monday";
      break;
    case TUESDAY:
      stream << "Tuesday";
      break;
    case WEDNESDAY:
      stream << "Wednesday";
      break;
    case THURSDAY:
      stream << "Thursday";
      break;
    case FRIDAY:
      stream << "Friday";
      break;
    case SATURDAY:
      stream << "Saturday";
      break;
    case SUNDAY:
      stream << "Sunday";
      break;
  }

  return stream;
}

The boilerplate code is indeed pretty big compared to some other methods presented in this thread. Still, it has the avantage of being pretty straightforward and easy to use.

std::cout << "First day of the week is " << WeekDay::Monday << std::endl;

I would suggest you to give diff-so-fancy a try. I use it during my work and it sure seems great as of now. It comes packed with many options and it's really easy to configure your diffs the way you want.

You can install it by:

sudo npm install -g diff-so-fancy

or on Mac:

brew install diff-so-fancy

Afterwards, you can highlight your diffs like this:

diff -u file1 file2 | diff-so-fancy

Time to go back in time for a lesson. While we don't think about these things much in our fancy managed languages today, they are built on the same foundation, so let's look at how memory is managed in C.

Before I dive in, a quick explanation of what the term "pointer" means. A pointer is simply a variable that "points" to a location in memory. It doesn't contain the actual value at this area of memory, it contains the memory address to it. Think of a block of memory as a mailbox. The pointer would be the address to that mailbox.

In C, an array is simply a pointer with an offset, the offset specifies how far in memory to look. This provides O(1) access time.

  MyArray   [5]
     ^       ^
  Pointer  Offset

All other data structures either build upon this, or do not use adjacent memory for storage, resulting in poor random access look up time (Though there are other benefits to not using sequential memory).

For example, let's say we have an array with 6 numbers (6,4,2,3,1,5) in it, in memory it would look like this:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================

In an array, we know that each element is next to each other in memory. A C array (Called MyArray here) is simply a pointer to the first element:

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^
MyArray

If we wanted to look up MyArray[4], internally it would be accessed like this:

MyArray + 4 ---------------/
(Pointer + Offset)

Because we can directly access any element in the array by adding the offset to the pointer, we can look up any element in the same amount of time, regardless of the size of the array. This means that getting MyArray[1000] would take the same amount of time as getting MyArray[5].

An alternative data structure is a linked list. This is a linear list of pointers, each pointing to the next node

========    ========    ========    ========    ========
| Data |    | Data |    | Data |    | Data |    | Data |
|      | -> |      | -> |      | -> |      | -> |      | 
|  P1  |    |  P2  |    |  P3  |    |  P4  |    |  P5  |        
========    ========    ========    ========    ========

P(X) stands for Pointer to next node.

Note that I made each "node" into its own block. This is because they are not guaranteed to be (and most likely won't be) adjacent in memory.

If I want to access P3, I can't directly access it, because I don't know where it is in memory. All I know is where the root (P1) is, so instead I have to start at P1, and follow each pointer to the desired node.

This is a O(N) look up time (The look up cost increases as each element is added). It is much more expensive to get to P1000 compared to getting to P4.

Higher level data structures, such as hashtables, stacks and queues, all may use an array (or multiple arrays) internally, while Linked Lists and Binary Trees usually use nodes and pointers.

You might wonder why anyone would use a data structure that requires linear traversal to look up a value instead of just using an array, but they have their uses.

Take our array again. This time, I want to find the array element that holds the value '5'.

=====================================
|  6  |  4  |  2  |  3  |  1  |  5  |
=====================================
   ^     ^     ^     ^     ^   FOUND!

In this situation, I don't know what offset to add to the pointer to find it, so I have to start at 0, and work my way up until I find it. This means I have to perform 6 checks.

Because of this, searching for a value in an array is considered O(N). The cost of searching increases as the array gets larger.

Remember up above where I said that sometimes using a non sequential data structure can have advantages? Searching for data is one of these advantages and one of the best examples is the Binary Tree.

A Binary Tree is a data structure similar to a linked list, however instead of linking to a single node, each node can link to two children nodes.

         ==========
         |  Root  |         
         ==========
        /          \ 
  =========       =========
  | Child |       | Child |
  =========       =========
                  /       \
            =========    =========
            | Child |    | Child |
            =========    =========

 Assume that each connector is really a Pointer

When data is inserted into a binary tree, it uses several rules to decide where to place the new node. The basic concept is that if the new value is greater than the parents, it inserts it to the left, if it is lower, it inserts it to the right.

This means that the values in a binary tree could look like this:

         ==========
         |   100  |         
         ==========
        /          \ 
  =========       =========
  |  200  |       |   50  |
  =========       =========
                  /       \
            =========    =========
            |   75  |    |   25  |
            =========    =========

When searching a binary tree for the value of 75, we only need to visit 3 nodes ( O(log N) ) because of this structure:

• Is 75 less than 100? Look at Right Node
• Is 75 greater than 50? Look at Left Node
• There is the 75!

Even though there are 5 nodes in our tree, we did not need to look at the remaining two, because we knew that they (and their children) could not possibly contain the value we were looking for. This gives us a search time that at worst case means we have to visit every node, but in the best case we only have to visit a small portion of the nodes.

That is where arrays get beat, they provide a linear O(N) search time, despite O(1) access time.

This is an incredibly high level overview on data structures in memory, skipping over a lot of details, but hopefully it illustrates an array's strength and weakness compared to other data structures.

Use either JavaScript or jQuery for this.

Using JavaScript

<script>
function val() {
    d = document.getElementById("select_id").value;
    alert(d);
}
</script>

<select onchange="val()" id="select_id">

Using jQuery

$('#select_id').change(function(){
    alert($(this).val());
})

If you run a loop taking items from z, how do you expect them not to be in z? IMHO it would make more sense comparing items from a different list to z.

Try using additional condition in join:

SELECT Table1.Col1, Table1.Col2, Table1.Col3, Table2.Col4
FROM Table1 
INNER JOIN Table2
ON (Table1.Col1 = Table2.Col1 
    OR (Table1.Col1 IS NULL AND Table2.Col1 IS NULL)
   )

As per RFC 1738:

Unsafe:

Characters can be unsafe for a number of reasons. The space character is unsafe because significant spaces may disappear and insignificant spaces may be introduced when URLs are transcribed or typeset or subjected to the treatment of word-processing programs. The characters "<" and ">" are unsafe because they are used as the delimiters around URLs in free text; the quote mark (""") is used to delimit URLs in some systems. The character "#" is unsafe and should always be encoded because it is used in World Wide Web and in other systems to delimit a URL from a fragment/anchor identifier that might follow it. The character "%" is unsafe because it is used for encodings of other characters. Other characters are unsafe because gateways and other transport agents are known to sometimes modify such characters. These characters are "{", "}", "|", "\", "^", "~", "[", "]", and "`".

All unsafe characters must always be encoded within a URL. For example, the character "#" must be encoded within URLs even in systems that do not normally deal with fragment or anchor identifiers, so that if the URL is copied into another system that does use them, it will not be necessary to change the URL encoding.

System.setProperty is not working for applets. Because JVM already running before applet start. In this case we use applet parameters like this:

    deployJava.runApplet({
        id: 'MyApplet',
        code: 'com.mkysoft.myapplet.SomeClass',
        archive: 'com.mkysoft.myapplet.jar'
    }, {
        java_version: "1.6*", // Target version
        cache_option: "no",
        cache_archive: "",
        codebase_lookup: true,
        java_arguments: "-Djava.net.preferIPv4Stack=true"
    },
       "1.6" // Minimum version
    );

You can find deployJava.js at https://www.java.com/js/deployJava.js

You can Use this for Curl:

function fakeip()  
{  
    return long2ip( mt_rand(0, 65537) * mt_rand(0, 65535) );   
}  

function getdata($url,$args=false) 
{ 
    global $session; 
    $ch = curl_init(); 
    curl_setopt($ch, CURLOPT_URL,$url); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, array("REMOTE_ADDR: ".fakeip(),"X-Client-IP: ".fakeip(),"Client-IP: ".fakeip(),"HTTP_X_FORWARDED_FOR: ".fakeip(),"X-Forwarded-For: ".fakeip())); 
    if($args) 
    { 
        curl_setopt($ch, CURLOPT_POST, 1); 
        curl_setopt($ch, CURLOPT_POSTFIELDS,$args); 
    } 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 
    //curl_setopt($ch, CURLOPT_PROXY, "127.0.0.1:8888"); 
    $result = curl_exec ($ch); 
    curl_close ($ch); 
    return $result; 
} 

Then To Read Json:

$result=getdata("https://example.com");

Then :

///Deocde Json
$data = json_decode($result,true);
///Count
             $total=count($data);
             $Str='<h1>Total : '.$total.'';
             echo $Str;
//You Can Also Make In Table:
             foreach ($data as $key => $value)
              {
          echo '  <td><font  face="calibri"color="red">'.$value[type].'   </font></td><td><font  face="calibri"color="blue">'.$value[category].'   </font></td><td><font  face="calibri"color="green">'.$value[amount].'   </font></tr><tr>';

           }
           echo "</tr></table>";
           }

You Can Also Use This:

echo '<p>Name : '.$data['result']['name'].'</p>
      <img src="'.$data['result']['pic'].'"><br>';

Hope this helped.

In some cases your directive runs twice when you simply not correct close you directive like this:

<my-directive>Some content<my-directive>

This will run your directive twice. Also there is another often case when your directive runs twice:

make sure you are not including your directive in your index.html TWICE!

The standard option grep -l (that is a lowercase L) could do this.

From the Unix standard:

-l
    (The letter ell.) Write only the names of files containing selected
    lines to standard output. Pathnames are written once per file searched.
    If the standard input is searched, a pathname of (standard input) will
    be written, in the POSIX locale. In other locales, standard input may be
    replaced by something more appropriate in those locales.

You also do not need -H in this case.

I store my data this way:

accountsTable ->
  key1 -> account1
  key2 -> account2

in order to get object data:

accountsDb = mDatabase.child("accountsTable");

accountsDb.child("some   key").addListenerForSingleValueEvent(new ValueEventListener() {
                @Override
                public void onDataChange(DataSnapshot snapshot) {

                    try{

                        Account account  = snapshot.getChildren().iterator().next()
                                  .getValue(Account.class);


                    } catch (Throwable e) {
                        MyLogger.error(this, "onCreate eror", e);
                    }
                }
                @Override public void onCancelled(DatabaseError error) { }
            });

SSL development libraries have to be installed

CentOS:

$ yum install openssl-devel libffi-devel

Ubuntu:

$ apt-get install libssl-dev libffi-dev

OS X (with Homebrew installed):

$ brew install openssl

What worked for me is the following (in view of the confusion in other answers):

<td style="text-align:center;">
    <input type="radio" name="ageneral" value="male">
</td>

The proposed solution (text-align) works but must be used in a style attribute.

I can't guarantee it's the simplest, but I like MarkerWithLabel. As shown in the basic example, CSS styles define the label's appearance and options in the JavaScript define the content and placement.

 .labels {
   color: red;
   background-color: white;
   font-family: "Lucida Grande", "Arial", sans-serif;
   font-size: 10px;
   font-weight: bold;
   text-align: center;
   width: 60px;     
   border: 2px solid black;
   white-space: nowrap;
 }

JavaScript:

 var marker = new MarkerWithLabel({
   position: homeLatLng,
   draggable: true,
   map: map,
   labelContent: "$425K",
   labelAnchor: new google.maps.Point(22, 0),
   labelClass: "labels", // the CSS class for the label
   labelStyle: {opacity: 0.75}
 });

The only part that may be confusing is the labelAnchor. By default, the label's top left corner will line up to the marker pushpin's endpoint. Setting the labelAnchor's x-value to half the width defined in the CSS width property will center the label. You can make the label float above the marker pushpin with an anchor point like new google.maps.Point(22, 50).

In case access to the links above are blocked, I copied and pasted the packed source of MarkerWithLabel into this JSFiddle demo. I hope JSFiddle is allowed in China :|

This is a solution based on extractors which will do the class cast:

class CC[T] { def unapply(a:Any):Option[T] = Some(a.asInstanceOf[T]) }

object M extends CC[Map[String, Any]]
object L extends CC[List[Any]]
object S extends CC[String]
object D extends CC[Double]
object B extends CC[Boolean]

val jsonString =
    """
      {
        "languages": [{
            "name": "English",
            "is_active": true,
            "completeness": 2.5
        }, {
            "name": "Latin",
            "is_active": false,
            "completeness": 0.9
        }]
      }
    """.stripMargin

val result = for {
    Some(M(map)) <- List(JSON.parseFull(jsonString))
    L(languages) = map("languages")
    M(language) <- languages
    S(name) = language("name")
    B(active) = language("is_active")
    D(completeness) = language("completeness")
} yield {
    (name, active, completeness)
}

assert( result == List(("English",true,2.5), ("Latin",false,0.9)))

At the start of the for loop I artificially wrap the result in a list so that it yields a list at the end. Then in the rest of the for loop I use the fact that generators (using <-) and value definitions (using =) will make use of the unapply methods.

(Older answer edited away - check edit history if you're curious)

You can also use START WITH to start a sequence from a particular point, although setval accomplishes the same thing, as in Euler's answer, eg,

SELECT MAX(a) + 1 FROM foo;
CREATE SEQUENCE foo_a_seq START WITH 12345; -- replace 12345 with max above
ALTER TABLE foo ALTER COLUMN a SET DEFAULT nextval('foo_a_seq');

You can use following regular expression construct

Punctuation: One of !"#$%&'()*+,-./:;<=>?@[]^_`{|}~

inputString.replaceAll("\\p{Punct}", "");

A point in favor of alias instead of alias_method is that its semantic is recognized by rdoc, leading to neat cross references in the generated documentation, while rdoc completely ignore alias_method.

Use property exists:

$post = new Post();
$post->exists = true;
$post->id = 3; //already exists in database.
$post->title = "Updated title";
$post->save();

Here is the API documentation: http://laravel.com/api/5.0/Illuminate/Database/Eloquent/Model.html

For the latest versions it is needed to install libxml++2.6-dev like that:

apt-get install libxml++2.6-dev

Type Chrome://flags in the address-bar

Search: Autoplay

Autoplay Policy

Policy used when deciding if audio or video is allowed to autoplay.

– Mac, Windows, Linux, Chrome OS, Android

Set this to "No user gesture is required"

Relaunch Chrome and you don't have to change any code

.center {
  display: table;
  margin: auto;
}

Plain form, without regex:

$prefix = 'bla_';
$str = 'bla_string_bla_bla_bla';

if (substr($str, 0, strlen($prefix)) == $prefix) {
    $str = substr($str, strlen($prefix));
} 

Takes: 0.0369 ms (0.000,036,954 seconds)

And with:

$prefix = 'bla_';
$str = 'bla_string_bla_bla_bla';
$str = preg_replace('/^' . preg_quote($prefix, '/') . '/', '', $str);

Takes: 0.1749 ms (0.000,174,999 seconds) the 1st run (compiling), and 0.0510 ms (0.000,051,021 seconds) after.

Profiled on my server, obviously.

You started with ManyToOne mapping , then you put OneToMany mapping as well for BiDirectional way. Then at OneToMany side (usually your parent table/class), you have to mention "mappedBy" (mapping is done by and in child table/class), so hibernate will not create EXTRA mapping table in DB (like TableName = parent_child).

Considere use DataBindingComplete event for update the style. The next code change the style of the cell:

    private void Grid_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        this.Grid.Rows[2].Cells[1].Style.BackColor = Color.Green;
    }

getopt Use command in your scripts to format any command line options or parameters.

#!/bin/bash
# Extract command line options & values with getopt
#
set -- $(getopt -q ab:cd "$@")
#
echo
while [ -n "$1" ]
do
case "$1" in
-a) echo "Found the -a option" ;;
-b) param="$2"
echo "Found the -b option, with parameter value $param"
shift ;;
-c) echo "Found the -c option" ;;
--) shift
break ;;
*) echo "$1 is not an option";;
esac
shift

You haven't specified what the query should return if more than one document is added at the same time, so this query assumes you want all of them returned:

SELECT t.ID,
       t.USER_ID,
       t.DATE_ADDED,
       t.DATE_VIEWED,
       t.DOCUMENT_ID,
       t.URL,
       t.DOCUMENT_TITLE,
       t.DOCUMENT_DATE
FROM (
  SELECT test_table.*,
         RANK()
         OVER (ORDER BY DOCUMENT_DATE DESC) AS the_rank
  FROM   test_table
  WHERE  user_id = value
  )
WHERE the_rank = 1;

This query will only make one pass through the data.

Addition to the answer of Brett DeWoody: (which is updated now)

var dataValue = obj.srcElement.attributes.data.nodeValue;

Works fine in IE(9+) and Chrome, but Firefox does not know the srcElement property. I found:

var dataValue = obj.currentTarget.attributes.data.nodeValue;

Works in IE, Chrome and FF, I did not test Safari.

The Accepted Answer is not working for me, This is what works for me

WebSettings webSetting = webView.getSettings();
    webSetting.setBuiltInZoomControls(true);
    webView1.setWebViewClient(new WebViewClient());

   webView.loadUrl("file:///android_asset/index.html");

If you happen to be using Autohotkey here's the script I use.

The key command is Ctrl+Delete. It only works if the VBE is active.
When pressed it will clear the immediate window and then activate the code editor, via F7.

I tend to want to clear the immediate when while I'm coding so now I can just hit Ctrl-Delete and keep coding.

#IfWinActive, ahk_class wndclass_desked_gsk

^Delete:: clearImmediateWindow()

#If

clearImmediateWindow() {
    Send, ^g
    Send, ^a
    Send, {Delete}
    Send, {F7}
}

I combined the two best solutions to cover all the possibilities:

BufferedReader br = new BufferedReader(new FileReader(fileName));     
File file = new File(fileName);
if (br.readLine() == null && file.length() == 0)
{
    System.out.println("No errors, and file empty");
}                
else
{
    System.out.println("File contains something");
}

More simple: SELECT max(id) FROM client

In objective-c :

NSArray *myArray = [myMutableArray copy];

In swift :

 var arr = myMutableArray as NSArray

Try mapping it. Try placing this code in your UserControl:

public event EventHandler ValueChanged {
  add { numericUpDown1.ValueChanged += value; }
  remove { numericUpDown1.ValueChanged -= value; }
}

then your UserControl will have the ValueChanged event you normally see with the NumericUpDown control.

Well, there could be many solutions to this problem like scraping the version code from App Page (Google Play App page), etc.

But I am going to show you the ultimate solution that won't cost a penny and will work like magic.

1. Just save the latest Version code of your app on Firebase Remote
   Config panel
2. Fetch that version code value whenever the app is opened

3. Compare it with the current version code of the app, which you can get by the following code

   private int getCurrentVersionCode() {
   try {
       return getPackageManager().getPackageInfo(getPackageName(), 0).versionCode;
   } catch (NameNotFoundException e) {
       e.printStackTrace();
   }
   return -1;
   

   }

If the fetched version code is greater than the current version, show an AlertDialog asking to update the app. Otherwise, the app is already updated.

So, whenever you roll out the new version, you need to put that new version code in Firebase Remote config panel

You can read the whole tutorial on how to force users to update the app using Firebase Remote Config

You need to convert those to actual dates instead of strings, try this:

SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('2010-01-15','YYYY-MM-DD') AND TO_DATE('2010-01-17', 'YYYY-MM-DD');

Edited to deal with format as specified:

SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('15-JAN-10','DD-MON-YY') AND TO_DATE('17-JAN-10','DD-MON-YY');

To create your cell styles see: http://poi.apache.org/spreadsheet/quick-guide.html#CustomColors.

Custom colors

HSSF:

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
HSSFRow row = sheet.createRow((short) 0);
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue("Default Palette");

//apply some colors from the standard palette,
// as in the previous examples.
//we'll use red text on a lime background

HSSFCellStyle style = wb.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

HSSFFont font = wb.createFont();
font.setColor(HSSFColor.RED.index);
style.setFont(font);

cell.setCellStyle(style);

//save with the default palette
FileOutputStream out = new FileOutputStream("default_palette.xls");
wb.write(out);
out.close();

//now, let's replace RED and LIME in the palette
// with a more attractive combination
// (lovingly borrowed from freebsd.org)

cell.setCellValue("Modified Palette");

//creating a custom palette for the workbook
HSSFPalette palette = wb.getCustomPalette();

//replacing the standard red with freebsd.org red
palette.setColorAtIndex(HSSFColor.RED.index,
        (byte) 153,  //RGB red (0-255)
        (byte) 0,    //RGB green
        (byte) 0     //RGB blue
);
//replacing lime with freebsd.org gold
palette.setColorAtIndex(HSSFColor.LIME.index, (byte) 255, (byte) 204, (byte) 102);

//save with the modified palette
// note that wherever we have previously used RED or LIME, the
// new colors magically appear
out = new FileOutputStream("modified_palette.xls");
wb.write(out);
out.close();

XSSF:

 XSSFWorkbook wb = new XSSFWorkbook();
    XSSFSheet sheet = wb.createSheet();
    XSSFRow row = sheet.createRow(0);
    XSSFCell cell = row.createCell( 0);
    cell.setCellValue("custom XSSF colors");

    XSSFCellStyle style1 = wb.createCellStyle();
    style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));
    style1.setFillPattern(CellStyle.SOLID_FOREGROUND);

$('#signup').on("submit", function(event) {
    $form = $(this); //wrap this in jQuery

The Bitwise operators are used to perform operations a bit-level or to manipulate bits in different ways. The bitwise operations are found to be much faster and are some times used to improve the efficiency of a program. Basically, Bitwise operators can be applied to the integer types: long, int, short, char and byte.

Bitwise Shift Operators

They are classified into two categories left shift and the right shift.

• Left Shift(<<): The left shift operator, shifts all of the bits in value to the left a specified number of times. Syntax: value << num. Here num specifies the number of position to left-shift the value in value. That is, the << moves all of the bits in the specified value to the left by the number of bit positions specified by num. For each shift left, the high-order bit is shifted out (and ignored/lost), and a zero is brought in on the right. This means that when a left shift is applied to 32-bit compiler, bits are lost once they are shifted past bit position 31. If the compiler is of 64-bit then bits are lost after bit position 63.

Output: 6, Here the binary representation of 3 is 0...0011(considering 32-bit system) so when it shifted one time the leading zero is ignored/lost and all the rest 31 bits shifted to left. And zero is added at the end. So it became 0...0110, the decimal representation of this number is 6.

• In the case of a negative number:

Output: -2, In java negative number, is represented by 2's complement. SO, -1 represent by 2^32-1 which is equivalent to 1....11(Considering 32-bit system). When shifted one time the leading bit is ignored/lost and the rest 31 bits shifted to left and zero is added at the last. So it becomes, 11...10 and its decimal equivalent is -2. So, I think you get enough knowledge about the left shift and how its work.

• Right Shift(>>): The right shift operator, shifts all of the bits in value to the right a specified of times. Syntax: value >> num, num specifies the number of positions to right-shift the value in value. That is, the >> moves/shift all of the bits in the specified value of the right the number of bit positions specified by num. The following code fragment shifts the value 35 to the right by two positions:

Output: 8, As a binary representation of 35 in a 32-bit system is 00...00100011, so when we right shift it two times the first 30 leading bits are moved/shifts to the right side and the two low-order bits are lost/ignored and two zeros are added at the leading bits. So, it becomes 00....00001000, the decimal equivalent of this binary representation is 8. Or there is a simple mathematical trick to find out the output of this following code: To generalize this we can say that, x >> y = floor(x/pow(2,y)). Consider the above example, x=35 and y=2 so, 35/2^2 = 8.75 and if we take the floor value then the answer is 8.

Output:

But remember one thing this trick is fine for small values of y if you take the large values of y it gives you incorrect output.

• In the case of a negative number: Because of the negative numbers the Right shift operator works in two modes signed and unsigned. In signed right shift operator (>>), In case of a positive number, it fills the leading bits with 0. And In case of a negative number, it fills leading bits with 1. To keep the sign. This is called 'sign extension'.

Output: -5, As I explained above the compiler stores the negative value as 2's complement. So, -10 is represented as 2^32-10 and in binary representation considering 32-bit system 11....0110. When we shift/ move one time the first 31 leading bits got shifted in the right side and the low-order bit got lost/ignored. So, it becomes 11...0011 and the decimal representation of this number is -5 (How I know the sign of number? because the leading bit is 1). It is interesting to note that if you shift -1 right, the result always remains -1 since sign extension keeps bringing in more ones in the high-order bits.

• Unsigned Right Shift(>>>): This operator also shifts bits to the right. The difference between signed and unsigned is the latter fills the leading bits with 1 if the number is negative and the former fills zero in either case. Now the question arises why we need unsigned right operation if we get the desired output by signed right shift operator. Understand this with an example, If you are shifting something that does not represent a numeric value, you may not want sign extension to take place. This situation is common when you are working with pixel-based values and graphics. In these cases, you will generally want to shift a zero into the high-order bit no matter what it's the initial value was.

Output: 2147483647, Because -2 is represented as 11...10 in a 32-bit system. When we shift the bit by one, the first 31 leading bit is moved/shifts in right and the low-order bit is lost/ignored and the zero is added to the leading bit. So, it becomes 011...1111 (2^31-1) and its decimal equivalent is 2147483647.

It is really easy to do a bulk insert in Laravel using Eloquent or the query builder.

You can use the following approach.

$data = [
    ['user_id'=>'Coder 1', 'subject_id'=> 4096],
    ['user_id'=>'Coder 2', 'subject_id'=> 2048],
    //...
];

Model::insert($data); // Eloquent approach
DB::table('table')->insert($data); // Query Builder approach

In your case you already have the data within the $query variable.

I had this problem with my datasource in WildFly and Tomcat, connecting to a Oracle 10g.

I found that under certain conditions the statement wasn't closed even when the statement.close() was invoked. The problem was with the Oracle Driver we were using: ojdbc7.jar. This driver is intended for Oracle 12c and 11g, and it seems has some issues when is used with Oracle 10g, so I downgrade to ojdbc5.jar and now everything is running fine.

This implementation wrap entity exception to exception with detail text. It handles DbEntityValidationException, DbUpdateException, datetime2 range errors (MS SQL), and include key of invalid entity in message (useful when savind many entities at one SaveChanges call).

First, override SaveChanges in DbContext class:

public class AppDbContext : DbContext
{
    public override int SaveChanges()
    {
        try
        {
            return base.SaveChanges();
        }
        catch (DbEntityValidationException dbEntityValidationException)
        {
            throw ExceptionHelper.CreateFromEntityValidation(dbEntityValidationException);
        }
        catch (DbUpdateException dbUpdateException)
        {
            throw ExceptionHelper.CreateFromDbUpdateException(dbUpdateException);
        }
    }   

    public override async Task<int> SaveChangesAsync(CancellationToken cancellationToken)
    {
        try
        {
            return await base.SaveChangesAsync(cancellationToken);
        }
        catch (DbEntityValidationException dbEntityValidationException)
        {
            throw ExceptionHelper.CreateFromEntityValidation(dbEntityValidationException);
        }
        catch (DbUpdateException dbUpdateException)
        {
            throw ExceptionHelper.CreateFromDbUpdateException(dbUpdateException);
        }
    }

ExceptionHelper class:

public class ExceptionHelper
{
    public static Exception CreateFromEntityValidation(DbEntityValidationException ex)
    {
        return new Exception(GetDbEntityValidationMessage(ex), ex);
    }

    public static string GetDbEntityValidationMessage(DbEntityValidationException ex)
    {
        // Retrieve the error messages as a list of strings.
        var errorMessages = ex.EntityValidationErrors
            .SelectMany(x => x.ValidationErrors)
            .Select(x => x.ErrorMessage);

        // Join the list to a single string.
        var fullErrorMessage = string.Join("; ", errorMessages);

        // Combine the original exception message with the new one.
        var exceptionMessage = string.Concat(ex.Message, " The validation errors are: ", fullErrorMessage);
        return exceptionMessage;
    }

    public static IEnumerable<Exception> GetInners(Exception ex)
    {
        for (Exception e = ex; e != null; e = e.InnerException)
            yield return e;
    }

    public static Exception CreateFromDbUpdateException(DbUpdateException dbUpdateException)
    {
        var inner = GetInners(dbUpdateException).Last();
        string message = "";
        int i = 1;
        foreach (var entry in dbUpdateException.Entries)
        {
            var entry1 = entry;
            var obj = entry1.CurrentValues.ToObject();
            var type = obj.GetType();
            var propertyNames = entry1.CurrentValues.PropertyNames.Where(x => inner.Message.Contains(x)).ToList();
            // check MS SQL datetime2 error
            if (inner.Message.Contains("datetime2"))
            {
                var propertyNames2 = from x in type.GetProperties()
                                        where x.PropertyType == typeof(DateTime) ||
                                            x.PropertyType == typeof(DateTime?)
                                        select x.Name;
                propertyNames.AddRange(propertyNames2);
            }

            message += "Entry " + i++ + " " + type.Name + ": " + string.Join("; ", propertyNames.Select(x =>
                string.Format("'{0}' = '{1}'", x, entry1.CurrentValues[x])));
        }
        return new Exception(message, dbUpdateException);
    }
}

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

I was able to use the name attribute that you described in your example for the loop I am working on and it worked, perhaps because I created unique ids? I'm still considering whether I should switch to an editor template instead as mentioned in the links in another answer.

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "true", new {Name = item.Description.QuestionId, id = string.Format("CBY{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" }) Yes

    @Html.RadioButtonFor(modelItem => item.Answers.AnswerYesNo, "false", new { Name = item.Description.QuestionId, id = string.Format("CBN{0}", item.Description.QuestionId), onclick = "setDescriptionVisibility(this)" } ) No

 @Html.TextBox("Receivers", Model, new { @class = "form-control", style = "width: 300px", @readonly = "readonly" })

I would like to contribute with a simple example and the explanations I've found useful when I had to tackle this problem myself.

In this answer you will find some information about Python's GIL (global interpreter lock) and a simple day-to-day example written using multiprocessing.dummy plus some simple benchmarks.

Global Interpreter Lock (GIL)

Python doesn't allow multi-threading in the truest sense of the word. It has a multi-threading package, but if you want to multi-thread to speed your code up, then it's usually not a good idea to use it.

Python has a construct called the global interpreter lock (GIL). The GIL makes sure that only one of your 'threads' can execute at any one time. A thread acquires the GIL, does a little work, then passes the GIL onto the next thread.

This happens very quickly so to the human eye it may seem like your threads are executing in parallel, but they are really just taking turns using the same CPU core.

All this GIL passing adds overhead to execution. This means that if you want to make your code run faster then using the threading package often isn't a good idea.

There are reasons to use Python's threading package. If you want to run some things simultaneously, and efficiency is not a concern, then it's totally fine and convenient. Or if you are running code that needs to wait for something (like some I/O) then it could make a lot of sense. But the threading library won't let you use extra CPU cores.

Multi-threading can be outsourced to the operating system (by doing multi-processing), and some external application that calls your Python code (for example, Spark or Hadoop), or some code that your Python code calls (for example: you could have your Python code call a C function that does the expensive multi-threaded stuff).

Why This Matters

Because lots of people spend a lot of time trying to find bottlenecks in their fancy Python multi-threaded code before they learn what the GIL is.

Once this information is clear, here's my code:

#!/bin/python
from multiprocessing.dummy import Pool
from subprocess import PIPE,Popen
import time
import os

# In the variable pool_size we define the "parallelness".
# For CPU-bound tasks, it doesn't make sense to create more Pool processes
# than you have cores to run them on.
#
# On the other hand, if you are using I/O-bound tasks, it may make sense
# to create a quite a few more Pool processes than cores, since the processes
# will probably spend most their time blocked (waiting for I/O to complete).
pool_size = 8

def do_ping(ip):
    if os.name == 'nt':
        print ("Using Windows Ping to " + ip)
        proc = Popen(['ping', ip], stdout=PIPE)
        return proc.communicate()[0]
    else:
        print ("Using Linux / Unix Ping to " + ip)
        proc = Popen(['ping', ip, '-c', '4'], stdout=PIPE)
        return proc.communicate()[0]


os.system('cls' if os.name=='nt' else 'clear')
print ("Running using threads\n")
start_time = time.time()
pool = Pool(pool_size)
website_names = ["www.google.com","www.facebook.com","www.pinterest.com","www.microsoft.com"]
result = {}
for website_name in website_names:
    result[website_name] = pool.apply_async(do_ping, args=(website_name,))
pool.close()
pool.join()
print ("\n--- Execution took {} seconds ---".format((time.time() - start_time)))

# Now we do the same without threading, just to compare time
print ("\nRunning NOT using threads\n")
start_time = time.time()
for website_name in website_names:
    do_ping(website_name)
print ("\n--- Execution took {} seconds ---".format((time.time() - start_time)))

# Here's one way to print the final output from the threads
output = {}
for key, value in result.items():
    output[key] = value.get()
print ("\nOutput aggregated in a Dictionary:")
print (output)
print ("\n")

print ("\nPretty printed output: ")
for key, value in output.items():
    print (key + "\n")
    print (value)

Here a CSS animation fork of jezzipin's Solution, to seperate code from styling.

JS:

$(window).on("scroll touchmove", function () {
  $('#header_nav').toggleClass('tiny', $(document).scrollTop() > 0);
});

CSS:

.header {
  width:100%;
  height:100px;
  background: #26b;
  color: #fff;
  position:fixed;
  top:0;
  left:0;
  transition: height 500ms, background 500ms;
}
.header.tiny {
  height:40px;
  background: #aaa;
}

http://jsfiddle.net/sinky/S8Fnq/

On scroll/touchmove the css class "tiny" is set to "#header_nav" if "$(document).scrollTop()" is greater than 0.

CSS transition attribute animates the "height" and "background" attribute nicely.

CSS table display is ideal for this:

.parent {_x000D_
  display: table;_x000D_
  width: 100%;_x000D_
}_x000D_
.parent > div {_x000D_
  display: table-cell;_x000D_
}_x000D_
.child-left {_x000D_
  background: powderblue;_x000D_
}_x000D_
.child-right {_x000D_
  background: papayawhip;_x000D_
}

<div class="parent">_x000D_
  <div class="child-left">Short</div>_x000D_
  <div class="child-right">Tall<br>Tall</div>_x000D_
</div>

Original answer (assumed any column could be taller):

You're trying to make the parent's height dependent on the children's height and children's height dependent on parent's height. Won't compute. CSS Faux columns is the best solution. There's more than one way of doing that. I'd rather not use JavaScript.

All answers are correct with sc.textFile

I was just wondering why not wholeTextFiles For example, in this case...

val minPartitions = 2
val path = "/pathtohdfs"
    sc.wholeTextFiles(path,minPartitions)
      .flatMap{case (path, text) 
    ...

one limitation is that, we have to load small files otherwise performance will be bad and may lead to OOM.

Note :

• The wholefile should fit in to memory
• Good for file formats that are NOT splittable by line... such as XML files

None of the above solutions worked for me.

My venv was active. pip -V and which pip gave me the correct virtualenv path, but when I pip install-ed packages with activated venv, my pip freeze stayed empty.

All the environment variables were correct too.

Finally, I just changed pip and removed virtualenv:

easy_install pip==7.0.2

pip install pip==10

sudo pip uninstall virtualenv

Reinstall venv:

sudo pip install virtualenv

Create venv:

python -m virtualenv venv_name_here

And all packages installed correctly into my venv again.

I had this problem, but only in Visual Studio Code, not in ISE. Turns out I was using an x86 session in VSCode. I displayed the PowerShell Session Menu and switched to the x64 session, and all the modules began working without full paths. I am using Version 1.17.2, architecture x64 of VSCode. My modules were stored in the C:\Windows\System32\WindowsPowerShell\v1.0\Modules directory.

If using PostgreSql 9.5.1, please follow the below configuration:

1. Open hg_hba.conf in pgAdmin
2. Select your path, and open it, then add a setting
3. Restart postgresql service

ep = datetime.datetime(1970,1,1,0,0,0)
x = (datetime.datetime.utcnow()- ep).total_seconds()

This should be different from int(time.time()), but it is safe to use something like x % (60*60*24)

datetime — Basic date and time types:

Unlike the time module, the datetime module does not support leap seconds.

The official way to set the disabled attribute on an HTMLInputElement is this:

var input = document.querySelector('[name="myButton"]');
// Without querySelector API
// var input = document.getElementsByName('myButton').item(0);

// disable
input.setAttribute('disabled', true);
// enable
input.removeAttribute('disabled');

While @kaushar's answer is sufficient for enabling and disabling an HTMLInputElement, and is probably preferable for cross-browser compatibility due to IE's historically buggy setAttribute, it only works because Element properties shadow Element attributes. If a property is set, then the DOM uses the value of the property by default rather than the value of the equivalent attribute.

There is a very important difference between properties and attributes. An example of a true HTMLInputElement property is input.value, and below demonstrates how shadowing works:

var input = document.querySelector('#test');_x000D_
_x000D_
// the attribute works as expected_x000D_
console.log('old attribute:', input.getAttribute('value'));_x000D_
// the property is equal to the attribute when the property is not explicitly set_x000D_
console.log('old property:', input.value);_x000D_
_x000D_
// change the input's value property_x000D_
input.value = "My New Value";_x000D_
_x000D_
// the attribute remains there because it still exists in the DOM markup_x000D_
console.log('new attribute:', input.getAttribute('value'));_x000D_
// but the property is equal to the set value due to the shadowing effect_x000D_
console.log('new property:', input.value);

<input id="test" type="text" value="Hello World" />

That is what it means to say that properties shadow attributes. This concept also applies to inherited properties on the prototype chain:

_x000D_
Parent.prototype.property = 'ParentPrototype';_x000D_

I hope this clarifies any confusion about the difference between properties and attributes.

One of the way I like is this one , but may be good for small files

with open(fileName,'r') as content_file:
    content = content_file.read()
    lineCount = len(re.split("\n",content))
    words = re.split("\W+",content.lower())

To count words, there is two way, if you don't care about repetition you can just do

words_count = len(words)

if you want the counts of each word you can just do

import collections
words_count = collections.Counter(words) #Count the occurrence of each word

Try something like this (should work for Apache and IIS):

if (empty($_SERVER['HTTPS']) || $_SERVER['HTTPS'] === "off") {
    $location = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header('HTTP/1.1 301 Moved Permanently');
    header('Location: ' . $location);
    exit;
}

Ignoring the check results in a corrupted install. This is the only solution that worked for me:

1. Create a C# console app with the following code: Console.WriteLine(string.Format("{0,3}", CultureInfo.InstalledUICulture.Parent.LCID.ToString("X")).Replace(" ", "0"));

2. Run the app and get the 3 digit code.

3. Run > Regedit, open the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib

Now, if you don't have a folder underneath that path with the 3 digit code from step 2, create it. If you do have the folder, check that it has the "Counter" and "Help" values set under that path. It probably doesn't -- which is why the check fails.

Create the missing Counter and Help keys (REG_MULTI_SZ). For the values, copy them from the existing path above (probably 009).

The check should now pass.

Working successfuly :

 sudo apt install libjpeg8-dev zlib1g-dev 

You can use .map().

Pass each element in the current matched set through a function, producing a new jQuery object containing the return value.

As the return value is a jQuery object, which contains an array, it's very common to call .get() on the result to work with a basic array.

Use

var arr = $('input[name="pname[]"]').map(function () {
    return this.value; // $(this).val()
}).get();

<> is generally a good replacement for XOR wherever it can apply to booleans.

This article has a good discussion on this issue. You can use

SELECT * 
FROM Y
INNER JOIN X ON EXISTS(SELECT X.QID 
                       INTERSECT 
                       SELECT y.QID);

Well, deleting an element from array is basically just set difference with one element.

array_diff( [312, 401, 15, 401, 3], [401] ) // removing 401 returns [312, 15, 3]

It generalizes nicely, you can remove as many elements as you like at the same time, if you want.

Disclaimer: Note that my solution produces a new copy of the array while keeping the old one intact in contrast to the accepted answer which mutates. Pick the one you need.

As Anton Gogolev noted, FileStream reads 4096 bytes at a time by default, But you can specify any other value using the FileStream constructor:

new FileStream(file, FileMode.Open, FileAccess.Read, FileShare.ReadWrite, 16 * 1024 * 1024)

Note that Brad Abrams from Microsoft wrote in 2004:

there is zero benefit from wrapping a BufferedStream around a FileStream. We copied BufferedStream’s buffering logic into FileStream about 4 years ago to encourage better default performance

A list keeps order, dict and set don't: when you care about order, therefore, you must use list (if your choice of containers is limited to these three, of course;-).

dict associates with each key a value, while list and set just contain values: very different use cases, obviously.

set requires items to be hashable, list doesn't: if you have non-hashable items, therefore, you cannot use set and must instead use list.

set forbids duplicates, list does not: also a crucial distinction. (A "multiset", which maps duplicates into a different count for items present more than once, can be found in collections.Counter -- you could build one as a dict, if for some weird reason you couldn't import collections, or, in pre-2.7 Python as a collections.defaultdict(int), using the items as keys and the associated value as the count).

Checking for membership of a value in a set (or dict, for keys) is blazingly fast (taking about a constant, short time), while in a list it takes time proportional to the list's length in the average and worst cases. So, if you have hashable items, don't care either way about order or duplicates, and want speedy membership checking, set is better than list.

str.join() works fine in Python 3, you just need to get the order of the arguments correct

>>> str.join('.', ('a', 'b', 'c'))
'a.b.c'

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

If you want to ensure they all get called, use super at all levels.

vertical-align applies to the elements being aligned, not their parent element. To vertically align the div's children, do this instead:

div > * {
    vertical-align:middle;  // Align children to middle of line
}

See: http://jsfiddle.net/dfmx123/TFPx8/1186/

NOTE: vertical-align is relative to the current text line, not the full height of the parent div. If you wanted the parent div to be taller and still have the elements vertically centered, set the div's line-height property instead of its height. Follow jsfiddle link above for an example.

Use your bean class like this, if your JSON data starts with an an array object. it helps you.

Users[] bean = gson.fromJson(response,Users[].class);

Users is my bean class.

Response is my JSON data.

select age(timestamp_A, timestamp_B)

Answering to Igor's comment:

select age('2013-02-28 11:01:28'::timestamp, '2011-12-31 11:00'::timestamp);
              age              
-------------------------------
 1 year 1 mon 28 days 00:01:28

This should work:

 cat "$API" >> "$CONFIG"

You need to use the >> operator to append to a file. Redirecting with > causes the file to be overwritten. (truncated).

With Groovy, you don't need the includes, and can just do:

String oldDate = '04-DEC-2012'
Date date = Date.parse( 'dd-MMM-yyyy', oldDate )
String newDate = date.format( 'M-d-yyyy' )

println newDate

To print:

12-4-2012

Add this in config/app.php under aliases:-

'Input' => Illuminate\Support\Facades\Input::class,

You're almost correct, just misplaced a few quotes. Wrapping the whole thing in regular quotes will literally give you the string #demo + {this.state.id} - you need to indicate which are variables and which are string literals. Since anything inside {} is an inline JSX expression, you can do:

href={"#demo" + this.state.id}

This will use the string literal #demo and concatenate it to the value of this.state.id. This can then be applied to all strings. Consider this:

var text = "world";

And this:

{"Hello " + text + " Andrew"}

This will yield:

Hello world Andrew 

You can also use ES6 string interpolation/template literals with ` (backticks) and ${expr} (interpolated expression), which is closer to what you seem to be trying to do:

href={`#demo${this.state.id}`}

This will basically substitute the value of this.state.id, concatenating it to #demo. It is equivalent to doing: "#demo" + this.state.id.

Based on @MaBi 's answer, I made this:

trait ClassShortNameTrait
{
    public static function getClassShortName()
    {
        if ($pos = strrchr(static::class, '\\')) {
            return substr($pos, 1);
        } else {
            return static::class;
        }
    }
}

Which you may use like that:

namespace Foo\Bar\Baz;

class A
{
    use ClassShortNameTrait;
}

A::class returns Foo\Bar\Baz\A, but A::getClassShortName() returns A.

Works for PHP >= 5.5.

IMO, this is personal. I'm not putting any prefixes at all. Anyway, if code is meaned to be public, I think it should better has some prefixes, so it can be more readable.

Often large companies are using it's own so called 'developer rules'.
Btw, the funniest yet smartest i saw was DRY KISS (Dont Repeat Yourself. Keep It Simple, Stupid). :-)

Although this question is 5 years old I have come across a nice solution.

Use the 'DictionaryEntry' object to pair keys and values.

Set the 'DisplayMember' and 'ValueMember' properties to:

   Me.myComboBox.DisplayMember = "Key"
   Me.myComboBox.ValueMember = "Value"

To add items to the ComboBox:

   Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))

To retreive items like this:

MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)

As of now in 2017, you can just write

$(window).on('wheel', function(event){

  // deltaY obviously records vertical scroll, deltaX and deltaZ exist too
  if(event.originalEvent.deltaY < 0){
    // wheeled up
  }
  else {
    // wheeled down
  }
});

Works with current Firefox 51, Chrome 56, IE9+

Stable sort will always return same solution (permutation) on same input.

For instance [2,1,2] will be sorted using stable sort as permutation [2,1,3] (first is index 2, then index 1 then index 3 in sorted output) That mean that output is always shuffled same way. Other non stable, but still correct permutation is [2,3,1].

Quick sort is not stable sort and permutation differences among same elements depends on algorithm for picking pivot. Some implementations pick up at random and that can make quick sort yielding different permutations on same input using same algorithm.

Stable sort algorithm is necessary deterministic.

Frustratingly the Numpy package published to PyPI won't install on most Windows computers https://github.com/numpy/numpy/issues/5479

Instead:

1. Download the Numpy wheel for your Python version from http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
2. Install it from the command line pip install numpy-1.10.2+mkl-cp35-none-win_amd64.whl

echo produces a trailing newline character which is hashed too. Try:

/bin/echo -n foobar | sha256sum 

You can also count on multiple groups and their intersection:

self.session.query(func.count(Table.column1),Table.column1, Table.column2).group_by(Table.column1, Table.column2).all()

The query above will return counts for all possible combinations of values from both columns.

Since C++11 you should take it by value over const& more often than you might think.

If you are taking the std::shared_ptr (rather than the underlying type T), then you are doing so because you want to do something with it.

If you would like to copy it somewhere, it makes more sense to take it by copy, and std::move it internally, rather than taking it by const& and then later copying it. This is because you allow the caller the option to in turn std::move the shared_ptr when calling your function, thus saving yourself a set of increment and decrement operations. Or not. That is, the caller of the function can decide whether or not he needs the std::shared_ptr around after calling the function, and depending on whether or not move or not. This is not achievable if you pass by const&, and thus it is then preferably to take it by value.

Of course, if the caller both needs his shared_ptr around for longer (thus can not std::move it) and you don't want to create a plain copy in the function (say you want a weak pointer, or you only sometimes want to copy it, depending on some condition), then a const& might still be preferable.

For example, you should do

void enqueue(std::shared<T> t) m_internal_queue.enqueue(std::move(t));

over

void enqueue(std::shared<T> const& t) m_internal_queue.enqueue(t);

Because in this case you always create a copy internally

Would this parser help you?

https://github.com/fiann/jquery.ogp

It parses meta OG data to JSON, so you can just use the data directly. If you prefer, you can read/write them directly using JQuery, of course. For example:

$("meta[property='og:title']").attr("content", document.title);
$("meta[property='og:url']").attr("content", location.toString());

Note the single-quotes around the attribute values; this prevents parse errors in jQuery.

The above solutions are great for the scenario where you have a small number of Counters. If you have a big list of them though, something like this is much nicer:

from collections import Counter

A = Counter({'a':1, 'b':2, 'c':3})
B = Counter({'b':3, 'c':4, 'd':5}) 
C = Counter({'a': 5, 'e':3})
list_of_counts = [A, B, C]

total = sum(list_of_counts, Counter())

print(total)
# Counter({'c': 7, 'a': 6, 'b': 5, 'd': 5, 'e': 3})

The above solution is essentially summing the Counters by:

total = Counter()
for count in list_of_counts:
    total += count
print(total)
# Counter({'c': 7, 'a': 6, 'b': 5, 'd': 5, 'e': 3})

This does the same thing but I think it always helps to see what it is effectively doing underneath.

It seems the behavior of defer and async is browser dependent, at least on the execution phase. NOTE, defer only applies to external scripts. I'm assuming async follows same pattern.

In IE 11 and below, the order seems to be like this:

• async (could partially execute while page loading)
• none (could execute while page loading)
• defer (executes after page loaded, all defer in order of placement in file)

In Edge, Webkit, etc, the async attribute seems to be either ignored or placed at the end:

• data-pagespeed-no-defer (executes before any other scripts, while page is loading)
• none (could execute while page is loading)
• defer (waits until DOM loaded, all defer in order of placement in file)
• async (seems to wait until DOM loaded)

In newer browsers, the data-pagespeed-no-defer attribute runs before any other external scripts. This is for scripts that don't depend on the DOM.

NOTE: Use defer when you need an explicit order of execution of your external scripts. This tells the browser to execute all deferred scripts in order of placement in the file.

ASIDE: The size of the external javascripts did matter when loading...but had no effect on the order of execution.

If you're worried about the performance of your scripts, you may want to consider minification or simply loading them dynamically with an XMLHttpRequest.

This will do the trick, similar with Tiago's solution, return "source" table as well.

select [First name], [Last name], max(_tabloc) as _tabloc
from (
  select [First Name], [Last name], 't1' as _tabloc from table1
  union all
  select [First name], [Last name], 't2' as _tabloc from table2
) v
group by [Fist Name], [Last name]
having count(1)=1

result will contain differences between tables, in column _tabloc you will have table reference.

The easiest way is to use the create Manager method, which creates and saves the object in a single step.

for item in items:
    MyModel.objects.create(name=item.name)

This worked for me.

    link.href = href;
    link.setAttribute('download', 'config.json'); //or any other extension
    document.body.appendChild(link);
    link.click();
})

    return Promise.reject({ Error: 'Something Went Wrong', err });

your xml file :

               android:layout_width="wrap_content"
               android:layout_height="wrap_content"
               android:src="@drawable/image"
               android:scaleType="fitXY"
               android:adjustViewBounds="true"/>

your java file:

ImageView imageView = (ImageView)findViewById(R.id.imageView);
     int width = imageView.getDrawable().getIntrinsicWidth();
     int   height = imageView.getDrawable().getIntrinsicHeight();

I was struggling with this as well. I used an interceptor, it captures the response headers, then clone the headers(since headers are immutable objects) and then sends the modified headers. https://angular.io/guide/http#intercepting-requests-and-responses

A good solution if you are used to the chrome inspector tools is Pony debugger: https://github.com/square/PonyDebugger

It is a bit of a pain to setup, but once you do it work well. Be sure to use Safari instead of Chrome to use it though.

This should work across different SQL implementations.

POCO stands for "Plain Old CLR Object".

Referencing a channel within a conversation

To create a clickable reference to a channel in a Slack conversation, just type # followed by the channel name. For example: #general.

To grab a link to a channel through the Slack UI

To share the channel URL externally, you can grab its link by control-clicking (Mac) or right-clicking (Windows) on the channel name:

The link would look like this:

https://yourteam.slack.com/messages/C69S1L3SS

Note that this link doesn't change even if you change the name of the channel. So, it is better to use this link rather than the one based on channel's name.

To compose a URL for a channel based on channel name

https://yourteam.slack.com/channels/<channel_name>

Opening the above URL from a browser would launch the Slack client (if available) or open the slack channel on the browser itself.

To compose a URL for a direct message (DM) channel to a user

https://yourteam.slack.com/channels/<username>

More often, people use logical operators to shorten the statement syntax:

!defaults.slideshowWidth &&
  (defaults.slideshowWidth = obj.find('img').width() + 'px');

But in your particular case the syntax can be even simpler:

defaults.slideshowWidth = defaults.slideshowWidth || obj.find('img').width() + 'px';

This code will return the defaults.slideshowWidth value if the defaults.slideshowWidth is evaluated to true and obj.find('img').width() + 'px' value otherwise.

See Short-Circuit Evaluation of logical operators for details.

Not my code, but a good example i think

When you are looking for your "local" address, you should note that each machine has not only a single network interface, and each interface could has its own local address. Which means your machine is always owning several "local" addresses.

Different "local" addresses will be automatically chosen to use when you are connecting to different endpoints. For example, when you connect to google.com, you are using an "outside" local address; but when you connect to your localhost, your local address is always localhost itself, because localhost is just a loopback.

Below is showing how to find out your local address when you are communicating with google.com:

Socket socket = new Socket();
socket.connect(new InetSocketAddress("google.com", 80));
System.out.println(socket.getLocalAddress());
socket.close();

This works for Windows:

CMD> start vscode://file/o:/git/libzmq/builds/msvc/vs2017/libzmq.sln

But if the filepath has spaces, normally one would add double quotes around it, like this:

CMD> start "vscode://file/o:/git/lib zmq/builds/msvc/vs2017/libzmq.sln"

But this messes up with start, which can take a double-quoted title, so it will create a window with this name as the title and not open the project.

CMD> start "title" "vscode://file/o:/git/lib zmq/builds/msvc/vs2017/libzmq.sln"

I solved a similar issue applying some padding to the LinearLayout like this:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_height="match_parent"
    android:background="@drawable/app_background"
    android:padding="35dip">

This probably won't give you an exact percentage but can be easily graduated and avoid extra unnecessary layout elements.

For other users with the same problem. Here is a function i just made up.

It does NOT run on every mouse movement the user makes, or clears a timer every time the mouse moves.

<script>
// Timeout in seconds
var timeout = 10; // 10 seconds

// You don't have to change anything below this line, except maybe
// the alert('Welcome back!') :-)
// ----------------------------------------------------------------
var pos = '', prevpos = '', timer = 0, interval = timeout / 5 * 1000;
timeout = timeout * 1000 - interval;
function mouseHasMoved(e){
    document.onmousemove = null;
    prevpos = pos;
    pos = e.pageX + '+' + e.pageY;
    if(timer > timeout){
        timer = 0;
        alert('Welcome back!');
    }
}
setInterval(function(){
    if(pos == prevpos){
        timer += interval;
    }else{
        timer = 0;
        prevpos = pos;
    }
    document.onmousemove = function(e){
        mouseHasMoved(e);
    }
}, interval);
</script>

if (Date.now() >= exp * 1000) {
  return false;
}

in angular2 2.1.1 I was not able to catch the exception using the (data),(error) pattern, so I implemented it using .catch(...).

It's nice because it can be used with all other Observable chained methods like .retry .map etc.

import {Observable} from 'rxjs/Rx';


  Http
  .put(...)
  .catch(err =>  { 
     notify('UI error handling');
     return Observable.throw(err); // observable needs to be returned or exception raised
  })
  .subscribe(data => ...) // handle success

from documentation:

Returns

(Observable): An observable sequence containing elements from consecutive source sequences until a source sequence terminates successfully.

As far as I know, a browser session doesn't have an id.

If you mean the server session, that is usually stored in a cookie. The cookie that ASP.NET stores, for example, is named "ASP.NET_SessionId".

From Spring docs,

Embedded servlet containers - Add a Servlet, Filter or Listener to an application

To add a Servlet, Filter, or Servlet *Listener provide a @Bean definition for it.

Eg:

@Bean
public Filter compressFilter() {
    CompressingFilter compressFilter = new CompressingFilter();
    return compressFilter;
}

Add this @Bean config to your @Configuration class and filter will be registered on startup.

Also you can add Servlets, Filters, and Listeners using classpath scanning,

@WebServlet, @WebFilter, and @WebListener annotated classes can be automatically registered with an embedded servlet container by annotating a @Configuration class with @ServletComponentScan and specifying the package(s) containing the components that you want to register. By default, @ServletComponentScan will scan from the package of the annotated class.

1. Remove "Network Link Conditioner", open "System Preferences", press CTRL and click the "Network Link Conditioner" icon. Select "Remove".
2. Restart your computer
3. Download the dmg "Hardware IO tools" for your XCode version from https://developer.apple.com/download/, you need to be logged in to do this.
4. Open it and install "Network Link Conditioner"
5. Restart your computer one last time.

Of course! Just use the ALTER TABLE... syntax.

Example

ALTER TABLE YourTable
  ADD Foo INT NULL /*Adds a new int column existing rows will be 
                     given a NULL value for the new column*/

Or

ALTER TABLE YourTable
  ADD Bar INT NOT NULL DEFAULT(0) /*Adds a new int column existing rows will
                                    be given the value zero*/

In SQL Server 2008 the first one is a metadata only change. The second will update all rows.

In SQL Server 2012+ Enterprise edition the second one is a metadata only change too.

If you are using office 365 follow this steps:

1. check the password expiration time using Azure power shell :Get-MsolUser -All | select DisplayName, LastPasswordChangeTimeStamp
2. Change the password using a new password (not the old one). You can eventually go back to the old password but you need to change it twice.

Hope it helps!

I made a really dumb mistake and forgot to define name attributes for inputs in my html file.

So instead of

<input type="password" class="form-control" id="password">

I have this.

<input type="password" class="form-control" id="password" name="password">

Now request.body is populated like this: { password: 'hhiiii' }

I just edited my iPhone's 'hosts' file successfully (on Jailbroken iOS 4.0).

• Installed OpenSSH onto iPhone via Cydia
• Using a SFTP client like FileZilla on my computer, I connected to my iPhone
  • Address: [use your phone's IP address or hostname, eg. simophone.local]
  • Username: root
  • Password: alpine
• Located the /etc/hosts file
• Made a backup on my computer (in case I want to revert my changes later)
• Edited the hosts file in a decent text editor (such as Notepad++). See here for an explanation of the hosts file.
• Uploaded the changes, overwriting the hosts file on the iPhone

The phone does cache some webpages and DNS queries, so a reboot or clearing the cache may help. Hope that helps someone.

I would suggest mp3-tagger. Best thing about this is it is distributed under MIT License and supports all the required attributes.

- artist;
- album;
- song;
- track;
- comment;
- year;
- genre;
- band;
- composer;
- copyright;
- url;
- publisher.

Example:

from mp3_tagger import MP3File

# Create MP3File instance.
mp3 = MP3File('File_Name.mp3')

# Get all tags.
tags = mp3.get_tags()
print(tags)

It supports set, get, update and delete attributes of mp3 files.

I would also suggest that you explore the options offered by the jupyter themer. For more modest interface changes you may be satisfied with running the syntax:

jupyter-themer [-c COLOR, --color COLOR]
                      [-l LAYOUT, --layout LAYOUT]
                      [-t TYPOGRAPHY, --typography TYPOGRAPHY]

where the options offered by themer would provide you with a less onerous way of making some changes in to the look of Jupyter Notebook. Naturally, you may still to prefer edit the .css files if the changes you want to apply are elaborate.

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

I got the same issue, and I changed to IP and it working well

Go to System References --> Network --> Advanced --> Open TCP/IP tabs --> copy the IPv4 Address.

change that IP instead localhost

Hope this can help

To declare it:

var myArr = ["apples", "oranges", "bananas"];

To use it:

document.write("In my shopping basket I have " + myArr[0] + ", " + myArr[1] + ", and " + myArr[2]);

Something like this should work:

UPDATE
    table_Name
SET 
  column_A = CASE WHEN @flag = '1' THEN column_A + @new_value ELSE column_A END,
  column_B = CASE WHEN @flag = '0' THEN column_B + @new_value ELSE column_B END
WHERE
    ID = @ID

Riffing on Aaron Hakala's answer with useRef inspired by this answer https://stackoverflow.com/a/54316368/3893510

const myRef = useRef(null);

  const clickElement = (ref) => {
    ref.current.dispatchEvent(
      new MouseEvent('click', {
        view: window,
        bubbles: true,
        cancelable: true,
        buttons: 1,
      }),
    );
  };

And your JSX:

<button onClick={() => clickElement(myRef)}>Click<button/>
<input ref={myRef}>

In my case, I had to change the cell padding of an element that contained an input checkbox for a table that's being dynamically rendered with DataTables:

<td class="dt-center">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

After implementing the following line code within the initComplete function I was able to produce the correct padding, which fixed the rows from being displayed with an abnormally large height

 $('tbody td:has(input.a)').css('padding', '0px');

Now, you can see that the correct styles are being applied to the parent element:

<td class=" dt-center" style="padding: 0px;">
    <input class="a" name="constCheck" type="checkbox" checked="">
</td>

Essentially, this answer is an extension of @KP's answer, but the more collaboration of implementing this the better. In summation, I hope this helps someone else because it works! Lastly, thank you so much @KP for leading me in the right direction!

On Windows 7 , the only thing that worked for me is this. Go to Device Manager -> Under Android Phone -> Right Click and select 'enable'

How about this for instance :

var youtubeimgsrc = document.getElementById("youtubeimg").getAttribute('src');

Use:

window.location.replace(...)

See this Stack Overflow question for more information:

How do I redirect to another webpage?

Or perhaps it was this you remember:

var url = "http://stackoverflow.com";
$(location).attr('href',url);

I had this same error with ADT22. Resolved it checking "Android Private Libraries" in properties -> Java build path -> Order and export. If you are using any library projects, the same should be done for them as well.

If it's just you? Use what you want to use today; switch in mid-stream if you want.

Is it a team? Try to be editor-agnostic. Set standards for white-space (are tabs allowed? How many spaces does a tab represent?), but otherwise allow anyone to use whichever editor they want.

Is it a team doing pair-programming? That's where you may need a team-standard editor, just so that programmers can easily pass the keyboard.

To help implement a standard white-space policy in a shop where one or more coders is using Emacs: You can tell Emacs about your white-space policy with some comments stuck at the bottom of every file source file. For example,

# Local Variables:
# tab-width: 2
# ruby-indent-level: 2
# indent-tabs-mode: nil
# End:

Anyone using emacs (or xemacs) on that file will automatically get the group standard indentation.

This stuff comes from ES file explorer

Just go into this app > settings

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

@Min and @Max are used for validating numeric fields which could be String(representing number), int, short, byte etc and their respective primitive wrappers.

@Size is used to check the length constraints on the fields.

As per documentation @Size supports String, Collection, Map and arrays while @Min and @Max supports primitives and their wrappers. See the documentation.

The correct way to do this is as follows:

1. Run the command:

   sp_help [table name] 
   

2. Copy the name of the CONSTRAINT.

3. Drop the DEFAULT CONSTRAINT:

   ALTER TABLE [table name] DROP [NAME OF CONSTRAINT] 
   

4. Run the command below:

   ALTER TABLE [table name] ADD DEFAULT [DEFAULT VALUE] FOR [NAME OF COLUMN]
   

Functions are first class objects that can be:

• Defined within your function
• Created just like any other variable or object at any point in your function
• Returned from your function (which may seem obvious after the two above, but still)

To build on the example given by Kenny:

   function a(x) {
      var w = function b(y) {
        return x + y;
      }
      return w;
   };

   var returnedFunction = a(3);
   alert(returnedFunction(2));

Would alert you with 5.

a += b is essentially the same as a = a + b, except that:

• + always returns a newly allocated object, but += should (but doesn't have to) modify the object in-place if it's mutable (e.g. list or dict, but int and str are immutable).

• In a = a + b, a is evaluated twice.

• Python: Simple Statements

  • A simple statement is comprised within a single logical line.

If this is the first time you encounter the += operator, you may wonder why it matters that it may modify the object in-place instead of building a new one. Here is an example:

# two variables referring to the same list
>>> list1 = []
>>> list2 = list1

# += modifies the object pointed to by list1 and list2
>>> list1 += [0]
>>> list1, list2
([0], [0])

# + creates a new, independent object
>>> list1 = []
>>> list2 = list1
>>> list1 = list1 + [0]
>>> list1, list2
([0], [])

Kindly check Column ApplicationId datatype in Table aspnet_Users , ApplicationId column datatype should be uniqueidentifier .

*Your parameter order is passed wrongly , Parameter @id should be passed as first argument, but in your script it is placed in second argument..*

So error is raised..

Please refere sample script:

DECLARE @id uniqueidentifier
SET @id = NEWID()
Create Table #temp1(AppId uniqueidentifier)

insert into #temp1 values(@id)

Select * from #temp1

Drop Table #temp1

I also got the same error.I think it was because I clone it and try to push back. $ git push -u origin master This is the right command.Try that

Undoubtedly, for your purposes (which I assume is just a programming exercise), the best thing is to check your results against any of the listings of the digits of pi on the web.

And how do we know that those values are correct? Well, I could say that there are computer-science-y ways to prove that an implementation of an algorithm is correct.

More pragmatically, if different people use different algorithms, and they all agree to (pick a number) a thousand (million, whatever) decimal places, that should give you a warm fuzzy feeling that they got it right.

Historically, William Shanks published pi to 707 decimal places in 1873. Poor guy, he made a mistake starting at the 528th decimal place.

Very interestingly, in 1995 an algorithm was published that had the property that would directly calculate the nth digit (base 16) of pi without having to calculate all the previous digits!

Finally, I hope your initial algorithm wasn't pi/4 = 1 - 1/3 + 1/5 - 1/7 + ... That may be the simplest to program, but it's also one of the slowest ways to do so. Check out the pi article on Wikipedia for faster approaches.

Martin's solution is very similar to mine, however how would you handle a default descriptions when the desired translation isn't found ?

Would that require an IFNULL() and another SELECT statement for each field ?

The default translation would be stored in the same table, where a flag like "isDefault" indicates wether that description is the default description in case none has been found for the current language.

You can use the GNU profiler. It shows the call-graph as well! the command is gprof and you need to compile your code with some option.

You could better use the localStorage of the web browser.

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

Not tested, but I think you can do the following:

dataGrid.Rows[index].Selected = true;

or you could do the following (but again: not tested):

dataGrid.SelectedRows.Clear();
foreach(DataGridViewRow row in dataGrid.Rows)
{
    if(YOUR CONDITION)
       row.Selected = true;
}

None of the above solutions were suitable for my scenario, handling .Navigated and .FileDownload events seemed like a good fit but accessing the WebBrowser.Document property threw an UnauthorizedAccessException which is caused by cross frame scripting security (our web content contains frames - all on the same domain/address but frames have their own security holes that are being blocked).

For anyone using Bootstrap and having this problem, they use :active:focus as well as just :active and :focus so you'll need:

element:active:focus {
    outline: 0;
}

Hopefully saved someone some time figuring that one out, banged my head for bit wondering why such a simple thing wasn't working.

You can just do that too, it seems to work well too. sc create "Servicename" binPath= "Path\To\your\App.exe" DisplayName= "My Custom Service"

You can open the registry and add a string named Description in your service's registry key to add a little more descriptive information about it. It will be shown in services.msc.

Probably something like this:

original_list = dictionary.get('C1')
new_list = []
for item in original_list:
  new_list.append(item+10)
dictionary['C1'] = new_list

I know I am Late But This Is All You Need

var date = (new Date()).toISOString().split('T')[0];

toISOString() use built function of javascript.

cd = (new Date()).toISOString().split('T')[0];_x000D_
console.log(cd);_x000D_
alert(cd);

if no such option exists, then maybe there is a nice idiomatic one-liner for doing that ? like, using for...of, or similar ?

Indeed, there are several ways to convert a Set to an Array:

using Array.from

let array = Array.from(mySet);

Simply spreading the Set out in an array

let array = [...mySet];

The old fashion way, iterating and pushing to a new array (Sets do have forEach)

let array = [];
mySet.forEach(v => array.push(v));

Previously, using the non-standard, and now deprecated array comprehension syntax:

let array = [v for (v of mySet)];

You can always fall back to the good old WinAPI calls, although the amount of work involved is non-trivial. There is no requirement that .NET services be installed via a .NET-aware mechanism.

To install:

• Open the service manager via OpenSCManager.
• Call CreateService to register the service.
• Optionally call ChangeServiceConfig2 to set a description.
• Close the service and service manager handles with CloseServiceHandle.

To uninstall:

• Open the service manager via OpenSCManager.
• Open the service using OpenService.
• Delete the service by calling DeleteService on the handle returned by OpenService.
• Close the service and service manager handles with CloseServiceHandle.

The main reason I prefer this over using the ServiceInstaller/ServiceProcessInstaller is that you can register the service with your own custom command line arguments. For example, you might register it as "MyApp.exe -service", then if the user runs your app without any arguments you could offer them a UI to install/remove the service.

Running Reflector on ServiceInstaller can fill in the details missing from this brief explanation.

P.S. Clearly this won't have "the same effect as calling: InstallUtil MyService.exe" - in particular, you won't be able to uninstall using InstallUtil. But it seems that perhaps this wasn't an actual stringent requirement for you.

Using position:fixed has the side effect of scrolling the body to the top.

If you do not your body to scroll to the top, DO NOTE use position:fixed. Just disable touchmove on the body if the modal is open. Note: The modal itself is still able to scroll on touch (if larger than the screen).

CSS:

body.modal-open {
    overflow: hidden;
    width: 100%;
    /* NO position:fixed here*/
}

JS:

$('.modal').on('show.bs.modal', function (ev) { // prevent body from scrolling when modal opens
    $('body').bind('touchmove', function(e){
        if (!$(e.target).parents().hasClass( '.modal' )){ //only prevent touch move if it is not the modal
            e.preventDefault()
        }
    })
})
$('.modal').on('hide.bs.modal', function (e) { //unbind the touchmove restrictions from body when modal closes
    $('body').unbind('touchmove');
})

EDIT: Note, for very small modals, you might have to add the following line to your CSS:

.modal-dialog{
    height: 100%;
}

The -s option of read is not defined in the POSIX standard. See http://pubs.opengroup.org/onlinepubs/9699919799/utilities/read.html. I wanted something that would work for any POSIX shell, so I wrote a little function that uses stty to disable echo.

#!/bin/sh

# Read secret string
read_secret()
{
    # Disable echo.
    stty -echo

    # Set up trap to ensure echo is enabled before exiting if the script
    # is terminated while echo is disabled.
    trap 'stty echo' EXIT

    # Read secret.
    read "$@"

    # Enable echo.
    stty echo
    trap - EXIT

    # Print a newline because the newline entered by the user after
    # entering the passcode is not echoed. This ensures that the
    # next line of output begins at a new line.
    echo
}

This function behaves quite similar to the read command. Here is a simple usage of read followed by similar usage of read_secret. The input to read_secret appears empty because it was not echoed to the terminal.

[susam@cube ~]$ read a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=bar c=baz qux
[susam@cube ~]$ unset a b c

Here is another that uses the -r option to preserve the backslashes in the input. This works because the read_secret function defined above passes all arguments it receives to the read command.

[susam@cube ~]$ read -r a b c
foo \bar baz \qux
[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c
[susam@cube ~]$ read_secret -r a b c

[susam@cube ~]$ echo a=$a b=$b c=$c
a=foo b=\bar c=baz \qux
[susam@cube ~]$ unset a b c

Finally, here is an example that shows how to use the read_secret function to read a password in a POSIX compliant manner.

printf "Password: "
read_secret password
# Do something with $password here ...

Use this command to trigger the notification center notification from the terminal.

osascript -e 'display notification "Lorem ipsum dolor sit amet" with title "Title"'

What you are trying to do can be simplified down to this.

$('input:text').bind('focus blur', function() {_x000D_
    $(this).toggleClass('red');_x000D_
});

input{_x000D_
    background:#FFFFEE;_x000D_
}_x000D_
.red{_x000D_
    background-color:red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
_x000D_
<form>_x000D_
    <input class="calc_input" type="text" name="start_date" id="start_date" />_x000D_
    <input class="calc_input" type="text" name="end_date" id="end_date" />_x000D_
    <input class="calc_input" size="8" type="text" name="leap_year" id="leap_year" />_x000D_
</form>

Let me post a solution here for C++03 that I consider the cleanest possible.*

#define DECLARE_LAMBDA(NAME, RETURN_TYPE, FUNCTION) \
    struct { RETURN_TYPE operator () FUNCTION } NAME;

...

int main(){
  DECLARE_LAMBDA(demoLambda, void, (){ cout<<"I'm a lambda!"<<endl; });
  demoLambda();

  DECLARE_LAMBDA(plus, int, (int i, int j){
    return i+j;
  });
  cout << "plus(1,2)=" << plus(1,2) << endl;
  return 0;
}

(*) in the C++ world using macros is never considered clean.

I had a similar problem, it was due to a StringBuilder.ToString();

I use EventBus library to update Fragment content in ViewPager. The logic is simple, just like document of EventBus how to do. It is no need to control FragmentPagerAdapter instance. The code is here:

1: Define events

Define which message which is needed to update.

public class UpdateCountEvent {
    public final int count;

    public UpdateCountEvent(int count) {
        this.count = count;
    }
}

2.Prepare subscribers

Write below code in the Fragment which is needed update.

@Override
public void onStart() {
    super.onStart();
    EventBus.getDefault().register(this);
}

@Override
public void onStop() {
    EventBus.getDefault().unregister(this);  
    super.onStop();
}

public void onEvent(UpdateCountEvent event) {//get update message
    Toast.makeText(getActivity(), event.count, Toast.LENGTH_SHORT).show();
}

3.Post events

Write below code in other Activity or other Fragment which needs to update parameter

//input update message
EventBus.getDefault().post(new UpdateCountEvent(count));

%>% is similar to pipe in Unix. For example, in

a <- combined_data_set %>% group_by(Outlet_Identifier) %>% tally()

the output of combined_data_set will go into group_by and its output will go into tally, then the final output is assigned to a.

This gives you handy and easy way to use functions in series without creating variables and storing intermediate values.

You need the whole python package, with a setup.py file in it.

A package named foo would be:

foo # the installable package
+-- foo
¦   +-- __init__.py
¦   +-- bar.py
+-- setup.py

And install from github like:

$ pip install git+ssh://[email protected]/myuser/foo.git
or
$ pip install git+https://github.com/myuser/foo.git@v123
or
$ pip install git+https://github.com/myuser/foo.git@newbranch

Technically you don't need to install it globally if the node_modules folder in your local installation is in your PATH. Generally this isn't a good idea.

Alternatively if npm test references gulp then you can just type npm test and it'll run the local gulp.

I've never installed gulp globally -- I think it's bad form.

A priority queue is an abstract data type that captures the idea of a container whose elements have "priorities" attached to them. An element of highest priority always appears at the front of the queue. If that element is removed, the next highest priority element advances to the front.

The C++ standard library defines a class template priority_queue, with the following operations:

push: Insert an element into the prioity queue.

top: Return (without removing it) a highest priority element from the priority queue.

pop: Remove a highest priority element from the priority queue.

size: Return the number of elements in the priority queue.

empty: Return true or false according to whether the priority queue is empty or not.

The following code snippet shows how to construct two priority queues, one that can contain integers and another one that can contain character strings:

#include <queue>

priority_queue<int> q1;
priority_queue<string> q2;

The following is an example of priority queue usage:

#include <string>
#include <queue>
#include <iostream>

using namespace std;  // This is to make available the names of things defined in the standard library.

int main()
{
    piority_queue<string> pq; // Creates a priority queue pq to store strings, and initializes the queue to be empty.

    pq.push("the quick");
    pq.push("fox");
    pq.push("jumped over");
    pq.push("the lazy dog");

    // The strings are ordered inside the priority queue in lexicographic (dictionary) order:
    // "fox", "jumped over", "the lazy dog", "the quick"
    //  The lowest priority string is "fox", and the highest priority string is "the quick"

    while (!pq.empty()) {
       cout << pq.top() << endl;  // Print highest priority string
       pq.pop();                    // Remmove highest priority string
    }

    return 0;
}

The output of this program is:

the quick
the lazy dog
jumped over
fox

Since a queue follows a priority discipline, the strings are printed from highest to lowest priority.

Sometimes one needs to create a priority queue to contain user defined objects. In this case, the priority queue needs to know the comparison criterion used to determine which objects have the highest priority. This is done by means of a function object belonging to a class that overloads the operator (). The overloaded () acts as < for the purpose of determining priorities. For example, suppose we want to create a priority queue to store Time objects. A Time object has three fields: hours, minutes, seconds:

struct Time {
    int h; 
    int m; 
    int s;
};

class CompareTime {
    public:
    bool operator()(Time& t1, Time& t2) // Returns true if t1 is earlier than t2
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
}

A priority queue to store times according the the above comparison criterion would be defined as follows:

priority_queue<Time, vector<Time>, CompareTime> pq;

Here is a complete program:

#include <iostream>
#include <queue>
#include <iomanip>

using namespace std;

struct Time {
    int h; // >= 0
    int m; // 0-59
    int s; // 0-59
};

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2)
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
};

int main()
{
    priority_queue<Time, vector<Time>, CompareTime> pq;

    // Array of 4 time objects:

    Time t[4] = { {3, 2, 40}, {3, 2, 26}, {5, 16, 13}, {5, 14, 20}};

    for (int i = 0; i < 4; ++i)
       pq.push(t[i]);

    while (! pq.empty()) {
       Time t2 = pq.top();
       cout << setw(3) << t2.h << " " << setw(3) << t2.m << " " <<
       setw(3) << t2.s << endl;
       pq.pop();
    }

    return 0;
}

The program prints the times from latest to earliest:

5  16  13
5  14  20
3   2  40
3   2  26

If we wanted earliest times to have the highest priority, we would redefine CompareTime like this:

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2) // t2 has highest prio than t1 if t2 is earlier than t1
    {
       if (t2.h < t1.h) return true;
       if (t2.h == t1.h && t2.m < t1.m) return true;
       if (t2.h == t1.h && t2.m == t1.m && t2.s < t1.s) return true;
       return false;
    }
};

there's a better way

# Larger example
rows = [('2006-03-28', 'BUY', 'IBM', 1000, 45.00),
        ('2006-04-05', 'BUY', 'MSOFT', 1000, 72.00),
        ('2006-04-06', 'SELL', 'IBM', 500, 53.00)]
c.executemany('insert into stocks values (?,?,?,?,?)', rows)
connection.commit()

You can chain .fail() callback for error response.

$.get('http://example.com/page/2/', function(data){ 
   $(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
  //Error logic
})

Take a look at the source:

function socketCloseListener() {
  var socket = this;
  var parser = socket.parser;
  var req = socket._httpMessage;
  debug('HTTP socket close');
  req.emit('close');
  if (req.res && req.res.readable) {
    // Socket closed before we emitted 'end' below.
    req.res.emit('aborted');
    var res = req.res;
    res.on('end', function() {
      res.emit('close');
    });
    res.push(null);
  } else if (!req.res && !req._hadError) {
    // This socket error fired before we started to
    // receive a response. The error needs to
    // fire on the request.
    req.emit('error', createHangUpError());
    req._hadError = true;
  }
}

The message is emitted when the server never sends a response.

This answer is late but it might help someone like it helped me

Just ensure you have given the user permission for the destination file

sudo chown -R www-data:www-data /Users/George/Desktop/uploads/

You can use netcat command as well

[location of netcat]/netcat -zv [ip] [port]

or

nc -zv [ip] [port]

-z – sets nc to simply scan for listening daemons, without actually sending any data to them.
-v – enables verbose mode.

std::map will sort its elements by keys. It doesn't care about the values when sorting.

You can use std::vector<std::pair<K,V>> then sort it using std::sort followed by std::stable_sort:

std::vector<std::pair<K,V>> items;

//fill items

//sort by value using std::sort
std::sort(items.begin(), items.end(), value_comparer);

//sort by key using std::stable_sort
std::stable_sort(items.begin(), items.end(), key_comparer);

Note that while std::sort is chosen for performance reason, std::stable_sort is needed for correct ordering, as you want the order-by-value to be preserved.

@gsf noted in the comment, you could use only std::sort if you choose a comparer which compares values first, and IF they're equal, sort the keys.

auto cmp = [](std::pair<K,V> const & a, std::pair<K,V> const & b) 
{ 
     return a.second != b.second?  a.second < b.second : a.first < b.first;
};
std::sort(items.begin(), items.end(), cmp);

That should be efficient.

But wait, there is a better approach: store std::pair<V,K> instead of std::pair<K,V> and then you don't need any comparer at all — the standard comparer for std::pair would be enough, as it compares first (which is V) first then second which is K:

std::vector<std::pair<V,K>> items;
//...
std::sort(items.begin(), items.end());

That should work great.

if you have a parameter $string and want to replace it's apace to underscore(_).

$string = "Hello All.";
$newString = str_replace(' ', '_', $string);

output will be Hello_All.

The ps command (at least the procps version used by many Linux distributions) has a number of format fields that relate to the process start time, including lstart which always gives the full date and time the process started:

Note that in this case I ran a "ps -p 1" command at about 16:50, then spawned a new bash shell, then ran the "ps -p 1 -p $$" command within that shell shortly afterward....)

You can also use "shouldReceiveTouch" method of UIGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:     (UITouch *)touch {
     UIView *view = touch.view; 
     NSLog(@"%d", view.tag); 
}    

Dont forget to set delegate of your gesture recognizer.

tl;dr: REM is the documented and supported way to embed comments in batch files.

:: is essentially a blank label that can never be jumped to, whereas REM is an actual command that just does nothing. In neither case (at least on Windows 7) does the presence of redirection operators cause a problem.

However, :: is known to misbehave in blocks under certain circumstances, being parsed not as a label but as some sort of drive letter. I'm a little fuzzy on where exactly but that alone is enough to make me use REM exclusively. It's the documented and supported way to embed comments in batch files whereas :: is merely an artifact of a particular implementation.

Here is an example where :: produces a problem in a FOR loop.

This example will not work in a file called test.bat on your desktop:

@echo off
for /F "delims=" %%A in ('type C:\Users\%username%\Desktop\test.bat') do (
    ::echo hello>C:\Users\%username%\Desktop\text.txt
)
pause

While this example will work as a comment correctly:

@echo off
for /F "delims=" %%A in ('type C:\Users\%username%\Desktop\test.bat') do (
    REM echo hello>C:\Users\%username%\Desktop\text.txt
)
pause

The problem appears to be when trying to redirect output into a file. My best guess is that it is interpreting :: as an escaped label called :echo.

I have came after another solution to this...here is the code

    $('.selector').popover({
        html: true,
        trigger: 'manual',
        container: $(this).attr('id'),
        placement: 'top',
        content: function () {
            $return = '<div class="hover-hovercard"></div>';
        }
    }).on("mouseenter", function () {
        var _this = this;
        $(this).popover("show");
        $(this).siblings(".popover").on("mouseleave", function () {
            $(_this).popover('hide');
        });
    }).on("mouseleave", function () {
        var _this = this;
        setTimeout(function () {
            if (!$(".popover:hover").length) {
                $(_this).popover("hide")
            }
        }, 100);
    });

Multi-dimension arrays are (n-1)-dimension matrices.

So int[,] square = new int[2,2] is square matrix 2x2, int[,,] cube = new int [3,3,3] is a cube - square matrix 3x3. Proportionality is not required.

Jagged arrays are just array of arrays - an array where each cell contains an array.

So MDA are proportional, JD may be not! Each cell can contains an array of arbitrary length!

I had a similar issue so I found a workaround (remove hyperlink tags thanks to regular expressions so that only a paragraph tag remains). I posted this solution on https://github.com/python-openxml/python-docx/issues/85 BP

You can also use numpy loadtxt like

from numpy import loadtxt
lines = loadtxt("filename.dat", comments="#", delimiter=",", unpack=False)

This did it for my case.

             <ImageView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_centerHorizontal="true"
                android:scaleType="centerCrop"
                android:adjustViewBounds="true"
                />

You could use sweetalert: https://sweetalert.js.org/guides/

npm install sweetalert --save

Then, simply import it into your application:

import swal from 'sweetalert';

If you pass two arguments, the first one will be the modal's title, and the second one its text.

swal("Here's the title!", "...and here's the text!");

This snippet also solve this question with datePart function. I've also used the right() trick to perform a rpad(x,2,"0").

option explicit

Wscript.Echo "Today is " & myDate(now)

' date formatted as your request
Function myDate(dt)
    dim d,m,y, sep
    sep = "-"
    ' right(..) here works as rpad(x,2,"0")
    d = right("0" & datePart("d",dt),2)
    m = right("0" & datePart("m",dt),2)
    y = datePart("yyyy",dt)
    myDate= m & sep & d & sep & y
End Function

You can use this function

var datastring = $("#contactForm").serialize();
$.ajax({
    type: "POST",
    url: "your url.php",
    data: datastring,
    dataType: "json",
    success: function(data) {
        //var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
        // do what ever you want with the server response
    },
    error: function() {
        alert('error handling here');
    }
});

return type is json

EDIT: I use event.preventDefault to prevent the browser getting submitted in such scenarios.

Adding more data to the answer.

dataType: "jsonp" if it is a cross-domain call.

beforeSend: // this is a pre-request call back function

complete: // a function to be called after the request ends.so code that has to be executed regardless of success or error can go here

async: // by default, all requests are sent asynchronously

cache: // by default true. If set to false, it will force requested pages not to be cached by the browser.

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

You have to correctly override method equals() from class Object

Edit: I think that my first response was misunderstood probably because I was not too precise. So I decided to to add more explanations.

Why do you have to override equals()? Well, because this is in the domain of a developer to decide what does it mean for two objects to be equal. Reference equality is not enough for most of the cases.

For example, imagine that you have a HashMap whose keys are of type Person. Each person has name and address. Now, you want to find detailed bean using the key. The problem is, that you usually are not able to create an instance with the same reference as the one in the map. What you do is to create another instance of class Person. Clearly, operator == will not work here and you have to use equals().

But now, we come to another problem. Let's imagine that your collection is very large and you want to execute a search. The naive implementation would compare your key object with every instance in a map using equals(). That, however, would be very expansive. And here comes the hashCode(). As others pointed out, hashcode is a single number that does not have to be unique. The important requirement is that whenever equals() gives true for two objects, hashCode() must return the same value for both of them. The inverse implication does not hold, which is a good thing, because hashcode separates our keys into kind of buckets. We have a small number of instances of class Person in a single bucket. When we execute a search, the algorithm can jump right away to a correct bucket and only now execute equals for each instance. The implementation for hashCode() therefore must distribute objects as evenly as possible across buckets.

There is one more point. Some collections require a proper implementation of a hashCode() method in classes that are used as keys not only for performance reasons. The examples are: HashSet and LinkedHashSet. If they don’t override hashCode(), the default Object hashCode() method will allow multiple objects that you might consider "meaningfully equal" to be added to your "no duplicates allowed" set.

Some of the collections that use hashCode()

• HashSet
• LinkedHashSet
• HashMap

Have a look at those two classes from apache commons that will allow you to implement equals() and hashCode() easily

• EqualsBuilder
• HashCodeBuilder

Not to the point of the question (can be related though), but, if you bootstrap a new project and wondering why do you get the same error, it may come from the artifactId of spring-boot-starter-data-jpa in the dependency section. I gave the dependency below. You will need to define the database to get rid of this.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

For me it was related to the lack of virtual resources (Ram and CPU). Go to the virtual box, right click on device -> Setting and increase the value of each resource.

Data.frame[,'h_new_column'] <- as.integer(Data.frame[,'h_no'], breaks=c(1, 4, 7))
