There is an command line application called "ShowVer" at CodeProject:

ShowVer.exe command-line VERSIONINFO display program

As usual the application comes with an exe and the source code (VisualC++ 6).

Out outputs all the meta data available:

Clean project,Clean build folder,Restart Xcode. i just remove path at project goto > Build Settings > Search the keyword. Swift Compiler - General -> Objective-C Bridging header worked for me.

NSPredicate is only available in iPhone 3.0.

You won't notice that until try to run on device.

My answer might not be related to problem mention here, but I had same problem with Python 3.4 where Crypto.Cipher wasn't a valid import. So I tried installing PyCrypto and went into problems.

After some research I found with 3.4 you should use pycryptodome.

I install pycryptodome using pycharm and I was good.

from Crypto.Cipher import AES

After struggling for many days finally found a solution that works perfectly.

Mac OS open ~/Library folder (in your home directory) and delete the VirtulBox folder. This will remove all configurations and you can start the virtual box again!

Others look for .virtualbox folder in your home directory. Remove it and open VirtualBox should solve your issue.

Cheers!!

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

browser's back/forward button solution
I encountered the same problem and I solved it using the popstate event from the $window object and ui-router's $state object. A popstate event is dispatched to the window every time the active history entry changes.
The $stateChangeSuccess and $locationChangeSuccess events are not triggered on browser's button click even though the address bar indicates the new location.
So, assuming you've navigated from states main to folder to main again, when you hit back on the browser, you should be back to the folder route. The path is updated but the view is not and still displays whatever you have on main. try this:

angular
.module 'app', ['ui.router']
.run($state, $window) {

     $window.onpopstate = function(event) {

        var stateName = $state.current.name,
            pathname = $window.location.pathname.split('/')[1],
            routeParams = {};  // i.e.- $state.params

        console.log($state.current.name, pathname); // 'main', 'folder'

        if ($state.current.name.indexOf(pathname) === -1) {
            // Optionally set option.notify to false if you don't want 
            // to retrigger another $stateChangeStart event
            $state.go(
              $state.current.name, 
              routeParams,
              {reload:true, notify: false}
            );
        }
    };
}

back/forward buttons should work smoothly after that.

note: check browser compatibility for window.onpopstate() to be sure

Sometimes it's case sensitive. Have you tried going to http://localhost/phpMyAdmin?

Try this one.

FROM tblEmployeeDetails Employee 
LEFT JOIN tblEmployeeDetails Manager ON Employee.emp_mgr_id = Manager.emp_id

You can use DataColumn.Ordinal to get the index of the column in the DataTable. So if you need the next column as mentioned use Column.Ordinal + 1:

row[row.Table.Columns["ColumnName"].Ordinal + 1] = someOtherValue;

When calling a function that is declared with throws in Swift, you must annotate the function call site with try or try!. For example, given a throwing function:

func willOnlyThrowIfTrue(value: Bool) throws {
  if value { throw someError }
}

this function can be called like:

func foo(value: Bool) throws {
  try willOnlyThrowIfTrue(value)
}

Here we annotate the call with try, which calls out to the reader that this function may throw an exception, and any following lines of code might not be executed. We also have to annotate this function with throws, because this function could throw an exception (i.e., when willOnlyThrowIfTrue() throws, then foo will automatically rethrow the exception upwards.

If you want to call a function that is declared as possibly throwing, but which you know will not throw in your case because you're giving it correct input, you can use try!.

func bar() {
  try! willOnlyThrowIfTrue(false)
}

This way, when you guarantee that code won't throw, you don't have to put in extra boilerplate code to disable exception propagation.

try! is enforced at runtime: if you use try! and the function does end up throwing, then your program's execution will be terminated with a runtime error.

Most exception handling code should look like the above: either you simply propagate exceptions upward when they occur, or you set up conditions such that otherwise possible exceptions are ruled out. Any clean up of other resources in your code should occur via object destruction (i.e. deinit()), or sometimes via defered code.

func baz(value: Bool) throws {

  var filePath = NSBundle.mainBundle().pathForResource("theFile", ofType:"txt")
  var data = NSData(contentsOfFile:filePath)

  try willOnlyThrowIfTrue(value)

  // data and filePath automatically cleaned up, even when an exception occurs.
}

If for whatever reason you have clean up code that needs to run but isn't in a deinit() function, you can use defer.

func qux(value: Bool) throws {
  defer {
    print("this code runs when the function exits, even when it exits by an exception")
  }

  try willOnlyThrowIfTrue(value)
}

Most code that deals with exceptions simply has them propagate upward to callers, doing cleanup on the way via deinit() or defer. This is because most code doesn't know what to do with errors; it knows what went wrong, but it doesn't have enough information about what some higher level code is trying to do in order to know what to do about the error. It doesn't know if presenting a dialog to the user is appropriate, or if it should retry, or if something else is appropriate.

Higher level code, however, should know exactly what to do in the event of any error. So exceptions allow specific errors to bubble up from where they initially occur to the where they can be handled.

Handling exceptions is done via catch statements.

func quux(value: Bool) {
  do {
    try willOnlyThrowIfTrue(value)
  } catch {
    // handle error
  }
}

You can have multiple catch statements, each catching a different kind of exception.

  do {
    try someFunctionThatThowsDifferentExceptions()
  } catch MyErrorType.errorA {
    // handle errorA
  } catch MyErrorType.errorB {
    // handle errorB
  } catch {
    // handle other errors
  }

For more details on best practices with exceptions, see http://exceptionsafecode.com/. It's specifically aimed at C++, but after examining the Swift exception model, I believe the basics apply to Swift as well.

For details on the Swift syntax and error handling model, see the book The Swift Programming Language (Swift 2 Prerelease).

int randomWithRange(int min, int max)
{
   int range = (max - min) + 1;     
   return (int)(Math.random() * range) + min;
}

Output of randomWithRange(2, 5) 10 times:

5
2
3
3
2
4
4
4
5
4

The bounds are inclusive, ie [2,5], and min must be less than max in the above example.

EDIT: If someone was going to try and be stupid and reverse min and max, you could change the code to:

int randomWithRange(int min, int max)
{
   int range = Math.abs(max - min) + 1;     
   return (int)(Math.random() * range) + (min <= max ? min : max);
}

EDIT2: For your question about doubles, it's just:

double randomWithRange(double min, double max)
{
   double range = (max - min);     
   return (Math.random() * range) + min;
}

And again if you want to idiot-proof it it's just:

double randomWithRange(double min, double max)
{
   double range = Math.abs(max - min);     
   return (Math.random() * range) + (min <= max ? min : max);
}

After struggling much with the npm link command (suggested solution for developing local modules without publishing them to a registry or maintaining a separate copy in the node_modules folder), I built a small npm module to help with this issue.

The fix requires two easy steps.

First:

npm install lib-manager --save-dev

Second, add this to your package.json:

{  
  "name": "yourModuleName",  
  // ...
  "scripts": {
    "postinstall": "./node_modules/.bin/local-link"
  }
}

You can find everything you need to know about Gradle here: Gradle Plugin User Guide

Goals of the new Build System

The goals of the new build system are:

• Make it easy to reuse code and resources
• Make it easy to create several variants of an application, either for multi-apk distribution or for different flavors of an application
• Make it easy to configure, extend and customize the build process
• Good IDE integration

Why Gradle?

Gradle is an advanced build system as well as an advanced build toolkit allowing to create custom build logic through plugins.

Here are some of its features that made us choose Gradle:

• Domain Specific Language (DSL) to describe and manipulate the build logic
• Build files are Groovy based and allow mixing of declarative elements through the DSL and using code to manipulate the DSL elements to provide custom logic.
• Built-in dependency management through Maven and/or Ivy.
• Very flexible. Allows using best practices but doesn’t force its own way of doing things.
• Plugins can expose their own DSL and their own API for build files to use.
• Good Tooling API allowing IDE integration

try this one, which simulates a click on an anchor.

var a = document.createElement('a');
a.href='http://www.google.com';
a.target = '_blank';
document.body.appendChild(a);
a.click();

I really hate forms which don't tell me what input(s) is/are missing. So I improve the Dominic's answer - thanks for this.

In the css file set the "borderR" class to border has red color.

$('#<form_id>').submit(function () {
    var allIsOk = true;

    // Check if empty of not
    $(this).find( 'input[type!="hidden"]' ).each(function () {
        if ( ! $(this).val() ) { 
            $(this).addClass('borderR').focus();
            allIsOk = false;
        }
    });

    return allIsOk
});

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

JavaScript: addEventListener method registers the specified listener on the EventTarget(Element|document|Window) it's called on.

EventTarget.addEventListener(event_type, handler_function, Bubbling|Capturing);

Mouse, Keyboard events Example test in WebConsole:

var keyboard = function(e) {
    console.log('Key_Down Code : ' + e.keyCode);
};
var mouseSimple = function(e) {
    var element = e.srcElement || e.target;
    var tagName = element.tagName || element.relatedTarget;
    console.log('Mouse Over TagName : ' + tagName);    
};
var  mouseComplex = function(e) {
    console.log('Mouse Click Code : ' + e.button);
} 

window.document.addEventListener('keydown',   keyboard,      false);
window.document.addEventListener('mouseover', mouseSimple,   false);
window.document.addEventListener('click',     mouseComplex,  false);

removeEventListener method removes the event listener previously registered with EventTarget.addEventListener().

window.document.removeEventListener('keydown',   keyboard,     false);
window.document.removeEventListener('mouseover', mouseSimple,  false);
window.document.removeEventListener('click',     mouseComplex, false);

i prefer using React built-in API:

import React, {cloneElement, Component} from "react";
import PropTypes from "prop-types";

export class Test extends Component {
  render() {
    const {children, wrapper} = this.props;
    return (
      cloneElement(wrapper, {
        ...wrapper.props,
        children
      })
    );
  }
}

Test.propTypes = {
  wrapper: PropTypes.element,
  // ... other props
};

Test.defaultProps = {
  wrapper: <div/>,
  // ... other props
};

then you can replace the wrapper div with what ever you want:

<Test wrapper={<span className="LOL"/>}>
  <div>child1</div>
  <div>child2</div>
</Test> 

I found the answer to the second part of my questions. Yes, a class can implement an interface that is in a different class as long that the interface is declared as public.

Try this worked for me Add this dependency to your build.gradle File

Note about tag of tag (tagging a tag), which is at the origin of your issue, as Charles Bailey correctly pointed out in the comment:

Make sure you study this thread, as overriding a signed tag is not as easy:

• if you already pushed a tag, the git tag man page seriously advised against a simple git tag -f B to replace a tag name "A"

• don't try to recreate a signed tag with git tag -f (see the thread extract below)

  (it is about a corner case, but quite instructive about tags in general, and it comes from another SO contributor Jakub Narebski):

Please note that the name of tag (heavyweight tag, i.e. tag object) is stored in two places:

• in the tag object itself as a contents of 'tag' header (you can see it in output of "git show <tag>" and also in output of "git cat-file -p <tag>", where <tag> is heavyweight tag, e.g. v1.6.3 in git.git repository),
• and also is default name of tag reference (reference in "refs/tags/*" namespace) pointing to a tag object.
  Note that the tag reference (appropriate reference in the "refs/tags/*" namespace) is purely local matter; what one repository has in 'refs/tags/v0.1.3', other can have in 'refs/tags/sub/v0.1.3' for example.

So when you create signed tag 'A', you have the following situation (assuming that it points at some commit)

  35805ce   <--- 5b7b4ead  <=== refs/tags/A
  (commit)       tag A
                 (tag)

Please also note that "git tag -f A A" (notice the absence of options forcing it to be an annotated tag) is a noop - it doesn't change the situation.

If you do "git tag -f -s A A": note that you force owerwriting a tag (so git assumes that you know what you are doing), and that one of -s / -a / -m options is used to force annotated tag (creation of tag object), you will get the following situation

  35805ce   <--- 5b7b4ea  <--- ada8ddc  <=== refs/tags/A
  (commit)       tag A         tag A
                 (tag)         (tag)

Note also that "git show A" would show the whole chain down to the non-tag object...

The problem is that you're displaying time(), which is a UNIX timestamp based on GMT/UTC. That’s why it doesn’t change. date() on the other hand, formats the time based on that timestamp.

A timestamp is the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT).

echo date('Y-m-d H:i:s T', time()) . "<br>\n";
date_default_timezone_set('UTC');
echo date('Y-m-d H:i:s T', time()) . "<br>\n";

As per your requirement i have created a sample demo using Swift 4 in which you can encode/decode string and image as per your requirement.

• I have also added sample methods of relevant operations.

As of TypeScript 1.6, properties in object literals that do not have a corresponding property in the type they're being assigned to are flagged as errors.

Usually this error means you have a bug (typically a typo) in your code, or in the definition file. The right fix in this case would be to fix the typo. In the question, the property callbackOnLoactionHash is incorrect and should have been callbackOnLocationHash (note the mis-spelling of "Location").

This change also required some updates in definition files, so you should get the latest version of the .d.ts for any libraries you're using.

Example:

interface TextOptions {
    alignment?: string;
    color?: string;
    padding?: number;
}
function drawText(opts: TextOptions) { ... }
drawText({ align: 'center' }); // Error, no property 'align' in 'TextOptions'

But I meant to do that

There are a few cases where you may have intended to have extra properties in your object. Depending on what you're doing, there are several appropriate fixes

Type-checking only some properties

Sometimes you want to make sure a few things are present and of the correct type, but intend to have extra properties for whatever reason. Type assertions (<T>v or v as T) do not check for extra properties, so you can use them in place of a type annotation:

interface Options {
    x?: string;
    y?: number;
}

// Error, no property 'z' in 'Options'
let q1: Options = { x: 'foo', y: 32, z: 100 };
// OK
let q2 = { x: 'foo', y: 32, z: 100 } as Options;
// Still an error (good):
let q3 = { x: 100, y: 32, z: 100 } as Options;

These properties and maybe more

Some APIs take an object and dynamically iterate over its keys, but have 'special' keys that need to be of a certain type. Adding a string indexer to the type will disable extra property checking

Before

interface Model {
  name: string;
}
function createModel(x: Model) { ... }

// Error
createModel({name: 'hello', length: 100});

After

interface Model {
  name: string;
  [others: string]: any;
}
function createModel(x: Model) { ... }

// OK
createModel({name: 'hello', length: 100});

This is a dog or a cat or a horse, not sure yet

interface Animal { move; }
interface Dog extends Animal { woof; }
interface Cat extends Animal { meow; }
interface Horse extends Animal { neigh; }

let x: Animal;
if(...) {
  x = { move: 'doggy paddle', woof: 'bark' };
} else if(...) {
  x = { move: 'catwalk', meow: 'mrar' };
} else {
  x = { move: 'gallop', neigh: 'wilbur' };
}

Two good solutions come to mind here

Specify a closed set for x

// Removes all errors
let x: Dog|Cat|Horse;

or Type assert each thing

// For each initialization
  x = { move: 'doggy paddle', woof: 'bark' } as Dog;

This type is sometimes open and sometimes not

A clean solution to the "data model" problem using intersection types:

interface DataModelOptions {
  name?: string;
  id?: number;
}
interface UserProperties {
  [key: string]: any;
}
function createDataModel(model: DataModelOptions & UserProperties) {
 /* ... */
}
// findDataModel can only look up by name or id
function findDataModel(model: DataModelOptions) {
 /* ... */
}
// OK
createDataModel({name: 'my model', favoriteAnimal: 'cat' });
// Error, 'ID' is not correct (should be 'id')
findDataModel({ ID: 32 });

To link to a YouTube video so it plays in HD by default, use the following URL:

https://www.youtube.com/v/VIDEOID?version=3&vq=hd1080

Change VIDEOID to the YouTube video ID that you want to link to. When someone follows the link, it will display the highest-resolution available (up to 1080p) in full-screen mode. Unfortunately, vq=hd1080 does not work on the normal YouTube site (with comments and related videos).

Use :

FileInfo fInfo = new FileInfo('FilePath');
var fFirstTime = fInfo.CreationTime;
var fLastTime = fInfo.LastWriteTime;

First, you're using the modifiers under an incorrect assumption.

Pattern.MULTILINE or (?m) tells Java to accept the anchors ^ and $ to match at the start and end of each line (otherwise they only match at the start/end of the entire string).

Pattern.DOTALL or (?s) tells Java to allow the dot to match newline characters, too.

Second, in your case, the regex fails because you're using the matches() method which expects the regex to match the entire string - which of course doesn't work since there are some characters left after (\\W)*(\\S)* have matched.

So if you're simply looking for a string that starts with User Comments:, use the regex

^\s*User Comments:\s*(.*)

with the Pattern.DOTALL option:

Pattern regex = Pattern.compile("^\\s*User Comments:\\s+(.*)", Pattern.DOTALL);
Matcher regexMatcher = regex.matcher(subjectString);
if (regexMatcher.find()) {
    ResultString = regexMatcher.group(1);
} 

ResultString will then contain the text after User Comments:

If your project has .xcdatamodeld file (mean you are using coreData) then make sure the entities you formed go its Data Model Inspector and check Class has codegen, manual/None or classdefination. if it is class defination then make it manual/None and clean the project and run again. screenshots are given below:

I got here looking for a nice way to write rest endpoint tests with a fluent json builder. In my case I used JSONObject to construct a specialized builder. It need a bit of instrumentation, but the usage is really nice:

import lombok.SneakyThrows;
import org.json.JSONObject;

public class MemberJson extends JSONObject {

    @SneakyThrows
    public static MemberJson builder() {
        return new MemberJson();
    }

    @SneakyThrows
    public MemberJson name(String name) {
        put("name", name);
        return this;
    }

}

MemberJson.builder().name("Member").toString();

type ModifiedType = Modify<OriginalType, {
  a: number;
  b: number;
}>

interface ModifiedInterface extends Modify<OriginalType, {
  a: number;
  b: number;
}> {}

Inspired by ZSkycat's extends Omit solution, I came up with this:

type Modify<T, R> = Omit<T, keyof R> & R;

// before [email protected]
type Modify<T, R> = Pick<T, Exclude<keyof T, keyof R>> & R

Example:

interface OriginalInterface {
  a: string;
  b: boolean;
  c: number;
}

type ModifiedType  = Modify<OriginalInterface , {
  a: number;
  b: number;
}>

// ModifiedType = { a: number; b: number; c: number; }

Going step by step:

type R0 = Omit<OriginalType, 'a' | 'b'>        // { c: number; }
type R1 = R0 & {a: number, b: number }         // { a: number; b: number; c: number; }

type T0 = Exclude<'a' | 'b' | 'c' , 'a' | 'b'> // 'c'
type T1 = Pick<OriginalType, T0>               // { c: number; }
type T2 = T1 & {a: number, b: number }         // { a: number; b: number; c: number; }

That's not possible. localhost always defaults to the loopback device on the local operating system.
As your virtual machine runs its own operating system it has its own loopback device which you cannot access from the outside.

If you want to access it e.g. in a browser, connect to it using the local IP instead:

http://192.168.180.1:8000

This is just an example of course, you can find out the actual IP by issuing an ifconfig command on a shell in the guest operating system.

**Old Method:**
if(x){
   add(x);
}
New Method:
x && add(x);

Even assign operation also we can do with round brackets

exp.includes('regexp_replace') && (exp = exp.replace(/,/g, '@&'));

Here is the function which will print all permutations recursively.

public void Permutations(string input, StringBuilder sb)
    {
        if (sb.Length == input.Length)
        {
            Console.WriteLine(sb.ToString());
            return;
        }

        char[] inChar = input.ToCharArray();

        for (int i = 0; i < input.Length; i++)
        {
            if (!sb.ToString().Contains(inChar[i]))
            {
                sb.Append(inChar[i]);
                Permutations(input, sb);    
                RemoveChar(sb, inChar[i]);
            }
        }
    }

private bool RemoveChar(StringBuilder input, char toRemove)
    {
        int index = input.ToString().IndexOf(toRemove);
        if (index >= 0)
        {
            input.Remove(index, 1);
            return true;
        }
        return false;
    }

A decorator takes the function definition and creates a new function that executes this function and transforms the result.

@deco
def do():
    ...

is equivalent to:

do = deco(do)

Example:

def deco(func):
    def inner(letter):
        return func(letter).upper()  #upper
    return inner

This

@deco
def do(number):
    return chr(number)  # number to letter

is equivalent to this

def do2(number):
    return chr(number)

do2 = deco(do2)

65 <=> 'a'

print(do(65))
print(do2(65))
>>> B
>>> B

To understand the decorator, it is important to notice, that decorator created a new function do which is inner that executes function and transforms the result.

Use VBA's already existing Join function. VBA functions aren't exposed in Excel, so I wrap Join in a user-defined function that exposes its functionality. The simplest form is:

Function JoinXL(arr As Variant, Optional delimiter As String = " ")
    'arr must be a one-dimensional array.
    JoinXL = Join(arr, delimiter)
End Function

Example usage:

=JoinXL(TRANSPOSE(A1:A4)," ") 

entered as an array formula (using Ctrl-Shift-Enter).

Now, JoinXL accepts only one-dimensional arrays as input. In Excel, ranges return two-dimensional arrays. In the above example, TRANSPOSE converts the 4×1 two-dimensional array into a 4-element one-dimensional array (this is the documented behaviour of TRANSPOSE when it is fed with a single-column two-dimensional array).

For a horizontal range, you would have to do a double TRANSPOSE:

=JoinXL(TRANSPOSE(TRANSPOSE(A1:D1)))

The inner TRANSPOSE converts the 1×4 two-dimensional array into a 4×1 two-dimensional array, which the outer TRANSPOSE then converts into the expected 4-element one-dimensional array.

This usage of TRANSPOSE is a well-known way of converting 2D arrays into 1D arrays in Excel, but it looks terrible. A more elegant solution would be to hide this away in the JoinXL VBA function.

Since the question is How to generate random colors in matplotlib? and as I was searching for an answer concerning pie plots, I think it is worth to put an answer here (for pies)

import numpy as np
from random import sample
import matplotlib.pyplot as plt
import matplotlib.colors as pltc
all_colors = [k for k,v in pltc.cnames.items()]

fracs = np.array([600, 179, 154, 139, 126, 1185])
labels = ["label1", "label2", "label3", "label4", "label5", "label6"]
explode = ((fracs == max(fracs)).astype(int) / 20).tolist()

for val in range(2):
    colors = sample(all_colors, len(fracs))
    plt.figure(figsize=(8,8))
    plt.pie(fracs, labels=labels, autopct='%1.1f%%', 
            shadow=True, explode=explode, colors=colors)
    plt.legend(labels, loc=(1.05, 0.7), shadow=True)
    plt.show()

Output

The only portable way to achieve consistency between rooms and tags and making sure rooms are never returned after they had been deleted is locking them with SELECT FOR UPDATE.

However in some systems locking is a side effect of concurrency control, and you achieve the same results without specifying FOR UPDATE explicitly.

To solve this problem, Thread 1 should SELECT id FROM rooms FOR UPDATE, thereby preventing Thread 2 from deleting from rooms until Thread 1 is done. Is that correct?

This depends on the concurrency control your database system is using.

• MyISAM in MySQL (and several other old systems) does lock the whole table for the duration of a query.

• In SQL Server, SELECT queries place shared locks on the records / pages / tables they have examined, while DML queries place update locks (which later get promoted to exclusive or demoted to shared locks). Exclusive locks are incompatible with shared locks, so either SELECT or DELETE query will lock until another session commits.

• In databases which use MVCC (like Oracle, PostgreSQL, MySQL with InnoDB), a DML query creates a copy of the record (in one or another way) and generally readers do not block writers and vice versa. For these databases, a SELECT FOR UPDATE would come handy: it would lock either SELECT or the DELETE query until another session commits, just as SQL Server does.

When should one use REPEATABLE_READ transaction isolation versus READ_COMMITTED with SELECT ... FOR UPDATE?

Generally, REPEATABLE READ does not forbid phantom rows (rows that appeared or disappeared in another transaction, rather than being modified)

• In Oracle and earlier PostgreSQL versions, REPEATABLE READ is actually a synonym for SERIALIZABLE. Basically, this means that the transaction does not see changes made after it has started. So in this setup, the last Thread 1 query will return the room as if it has never been deleted (which may or may not be what you wanted). If you don't want to show the rooms after they have been deleted, you should lock the rows with SELECT FOR UPDATE

• In InnoDB, REPEATABLE READ and SERIALIZABLE are different things: readers in SERIALIZABLE mode set next-key locks on the records they evaluate, effectively preventing the concurrent DML on them. So you don't need a SELECT FOR UPDATE in serializable mode, but do need them in REPEATABLE READ or READ COMMITED.

Note that the standard on isolation modes does prescribe that you don't see certain quirks in your queries but does not define how (with locking or with MVCC or otherwise).

When I say "you don't need SELECT FOR UPDATE" I really should have added "because of side effects of certain database engine implementation".

AFAIK, there's no such shorthand for border. You have to define each border separately:

border: 0 solid #000;
border-left: 1px solid #000;
border-right: 1px solid #000;

//Mysql sum of multiple rows Hi Here is the simple way to do sum of columns

SELECT sum(IF(day_1 = 1,1,0)+IF(day_3 = 1,1,0)++IF(day_4 = 1,1,0)) from attendence WHERE class_period_id='1' and student_id='1'

Perl solution similar to Mat's awk solution:

perl -F'\|' -lane 'print $#F+1; exit' stores.dat

I've tested this on a file with 1000000 columns.

If the field separator is whitespace (one or more spaces or tabs) instead of a pipe:

perl -lane 'print $#F+1; exit' stores.dat

You can start Kitematic when you get this error. It will display a button to reset the VM and will fix the issue.

2 points in addition to all other good answers:

1:

what are the Grant Tables?

from dev.mysql.com

The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.

clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables

2:

note that if you perform:

UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';

and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:

mysql -u someuser -p

your access will be denied by your new password until you perform :

FLUSH PRIVILEGES;

For SQL Server 2008 run:

EXEC sp_defaultlanguage 'username', 'british'

I usually use AtomicInteger when I need to give Ids to objects that can be accesed or created from multiple threads, and i usually use it as an static attribute on the class that i access in the constructor of the objects.

Also WebClient doesn't have timeout property. And that's the problem, because dafault value is 100 seconds and that's too much to indicate if there's no Internet connection.

Workaround for that problem is here https://stackoverflow.com/a/3052637/1303422

If you have space in the name of the keys, you can use this in bash:

redis-cli keys "pattern: *" | xargs -L1 -I '$' echo '"$"' | xargs redis-cli del

Calendar cal = Calendar.getInstance(); 
cal.add(Calendar.MONTH, 1);
java.util.Date dt = cal.getTime();

this one works in ubuntu This command will cre android update project -p "project full path"

Small reusable method can be written for creating person json object to avoid duplicate code

JSONObject  getPerson(String firstName, String lastName){
   JSONObject person = new JSONObject();
   person .put("firstName", firstName);
   person .put("lastName", lastName);
   return person ;
} 

public JSONObject getJsonResponse(){

    JSONArray employees = new JSONArray();
    employees.put(getPerson("John","Doe"));
    employees.put(getPerson("Anna","Smith"));
    employees.put(getPerson("Peter","Jones"));

    JSONArray managers = new JSONArray();
    managers.put(getPerson("John","Doe"));
    managers.put(getPerson("Anna","Smith"));
    managers.put(getPerson("Peter","Jones"));

    JSONObject response= new JSONObject();
    response.put("employees", employees );
    response.put("manager", managers );
    return response;
  }

From the spec:

All characters may be placed within the quotation marks except for the characters that must be escaped: quotation mark (U+0022), reverse solidus [backslash] (U+005C), and the control characters U+0000 to U+001F

Just because e.g. Bell (U+0007) doesn't have a single-character escape code does not mean that you don't need to escape it. Use the Unicode escape sequence \u0007.

There's the % sign. It's not just for the remainder, it is the modulo operation.

Here's another approach.

git checkout {SOURCE_BRANCH}               # switch to Source branch.
git checkout {COMMIT_HASH}                 # go back to the desired commit.
git checkout -b {temp_branch}              # create a new temporary branch from {COMMIT_HASH} snapshot.
git checkout {TARGET_BRANCH}               # switch to Target branch.
git merge {temp_branch}                    # merge code to your Target branch.
git branch -d {temp_branch}                # delete the temp branch.

May be you can just use the split method to eliminate the '/myapp' for example:

string[] uris=request.getRequestURI().split("/");
string uri="/"+uri[1]+"/"+uris[2];

I've found this works well as a conditional within page.php that includes the WooCommerce cart and checkout screens.

!is_page(array('cart', 'checkout'))

You can always use Request.QueryString collection like Web forms, but you can also make MVC handle them and pass them as parameters. This is the suggested way as it's easier and it will validate input data type automatically.

Check your project build is in Debug mode not Release, I had some problem for debugging always I forget to change Release mode to Debug (Xamarin Users)

Never ever choose a fixed pivot - this can be attacked to exploit your algorithm's worst case O(n²) runtime, which is just asking for trouble. Quicksort's worst case runtime occurs when partitioning results in one array of 1 element, and one array of n-1 elements. Suppose you choose the first element as your partition. If someone feeds an array to your algorithm that is in decreasing order, your first pivot will be the biggest, so everything else in the array will move to the left of it. Then when you recurse, the first element will be the biggest again, so once more you put everything to the left of it, and so on.

A better technique is the median-of-3 method, where you pick three elements at random, and choose the middle. You know that the element that you choose won't be the the first or the last, but also, by the central limit theorem, the distribution of the middle element will be normal, which means that you will tend towards the middle (and hence, nlog(n) time).

If you absolutely want to guarantee O(nlog(n)) runtime for the algorithm, the columns-of-5 method for finding the median of an array runs in O(n) time, which means that the recurrence equation for quicksort in the worst case will be:

T(n) = O(n) (find the median) + O(n) (partition) + 2T(n/2) (recurse left and right)

By the Master Theorem, this is O(nlog(n)). However, the constant factor will be huge, and if worst case performance is your primary concern, use a merge sort instead, which is only a little bit slower than quicksort on average, and guarantees O(nlog(n)) time (and will be much faster than this lame median quicksort).

Explanation of the Median of Medians Algorithm

Just as Oded has answered. You need to have this sort of detection functionality in javascript.

I've struggled with this myself and realized that the offset is not enough. It does not give you any information about daylight saving for example. I ended up writing some code to map to zoneinfo database keys.

By checking several dates around a year you can more accurately determine a timezone.

Try the script here: http://jsfiddle.net/pellepim/CsNcf/

Simply change your system timezone and click run to test it. If you are running chrome you need to do each test in a new tab though (and safar needs to be restarted to pick up timezone changes).

If you want more details of the code check out: https://bitbucket.org/pellepim/jstimezonedetect/

Try Runscope. A free tool sampling their service is provided at https://www.hurl.it/ . You can set the method, authentication, headers, parameters, and body. Response shows status code, headers, and body. The response body can be formatted from JSON with a collapsable heirarchy. Paid accounts can automate test API calls and use return data to build new test calls. COI disclosure: I have no relationship to Runscope.

From your comment:

this line DateTime Date = reader.GetDateTime(0); was throwing the exception

The first column is not a valid DateTime. Most likely, you have multiple columns in your table, and you're retrieving them all by running this query:

SELECT * from INFO

Replace it with a query that retrieves only the two columns you're interested in:

SELECT YOUR_DATE_COLUMN, YOUR_TIME_COLUMN from INFO

Then try reading the values again:

var Date = reader.GetDateTime(0);
var Time = reader.GetTimeSpan(1);  // equivalent to time(7) from your database

Or:

var Date = Convert.ToDateTime(reader["YOUR_DATE_COLUMN"]);
var Time = (TimeSpan)reader["YOUR_TIME_COLUMN"];

Thanks to @pgregory, I could resolve my problem using this directive for inline editing

.directive("superEdit", function($compile){
    return{
        link: function(scope, element, attrs){
            var colName = attrs["superEdit"];
            alert(colName);

            scope.getContentUrl = function() {
                if (colName == 'Something') {
                    return 'app/correction/templates/lov-edit.html';
                }else {
                    return 'app/correction/templates/simple-edit.html';
                }
            }

            var template = '<div ng-include="getContentUrl()"></div>';

            var linkFn = $compile(template);
            var content = linkFn(scope);
            element.append(content);
        }
    }
})

On Mac OS X 10.9 Mavericks, the solution that worked is as follows

rvm pkg install openssl
CC=/usr/local/bin/gcc-4.2 CPP=/usr/local/bin/cpp-4.2 CXX=/usr/local/bin/g++-4.2  rvm install 1.9.3 --with-openssl-dir=$rvm_path/usr

This is to compile Ruby with OpenSSL Support. Next, uninstall all the old versions.

brew uninstall openssl
brew uninstall curl
brew uninstall git

Next, install the updated versions. The git installation is dependent on an updated version of CURL.

brew install openssl
brew install curl
brew install git

Try this

Try to set the different images for UIControlStateDisabled (disabled gray image) and UIControlStateNormal(Normal image) so the button generate the disabled state for you.

DialogFragment has a public getTheme() method that you can over ride for this exact reason. This solution uses less lines of code:

public class MyCustomDialogFragment extends DialogFragment{
    ...
    @Override
    public int getTheme() {
        return R.style.MyThemeWithCustomAnimation;
    }
}

Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:

Codepen sample using SVG

HTML

<div class="div1"></div>
<div class="div2"></div>

CSS

.div1:after, .div2:after {
  content: '';
  display: block;
  height: 80px;
  width: 80px;
  background-image: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20version%3D%221.1%22%20height%3D%2280%22%20width%3D%22160%22%3E%0D%0A%20%20%3Ccircle%20cx%3D%2240%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22red%22%20%2F%3E%0D%0A%20%20%3Ccircle%20cx%3D%22120%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22blue%22%20%2F%3E%0D%0A%3C%2Fsvg%3E);

.div2:after {

}

For IE8, change to this:

  background-image: url(data:image/png;base64,data......);

Other answers show how to use pip with both 2.X and 3.X Python, but does not show how to handle the case of multiple Python distributions (eg. original Python and Anaconda Python).

I have a total of 3 Python versions: original Python 2.7 and Python 3.5 and Anaconda Python 3.5.

Here is how I install a package into:

1. Original Python 3.5:

   /usr/bin/python3 -m pip install python-daemon
   

2. Original Python 2.7:

   /usr/bin/python -m pip install python-daemon
   

3. Anaconda Python 3.5:

   python3 -m pip install python-daemon
   

   or

   pip3 install python-daemon
   

   Simpler, as Anaconda overrides original Python binaries in user environment.

   Of course, installing in anaconda should be done with conda command, this is just an example.

Also, make sure that pip is installed for that specific python.You might need to manually install pip. This works in Ubuntu 16.04:

sudo apt-get install python-pip 

or

sudo apt-get install python3-pip

You can provide password as parameter to expect script.

It looks like this error 0xe0434352 applies to a number of different errors.

In case it helps anyone, I ran into this error when I was trying to install my application on a new Windows 10 installation. It worked on other machines, and looked like the app momentarily would start before dying. After much trial and error the problem turned out to be that the app required DirectX9. Though a later version of DirectX was present it had to have version 9. Hope that saves someone some frustration.

I prefer using the selector and I apply it on the document.

This binds itself on the document and will be applicable to the elements that will be rendered after page load.

For example:

$(document).on("click", 'selector', function() {
    // Your code here
});

UPDATE: This is wrong answer, but it's still useful to understand why it's wrong. See comments.

How about unicode-escape?

>>> d = {1: "??? ????", 2: u"??? ????"}
>>> json_str = json.dumps(d).decode('unicode-escape').encode('utf8')
>>> print json_str
{"1": "??? ????", "2": "??? ????"}

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

Not a directive solution but is working for me:

<input ng-model='user.password'
 type="password"
 name='password'
 placeholder='password'
 required>
<input ng-model='user.password_verify'
 type="password" 
 name='confirm_password'
 placeholder='confirm password'
 ng-pattern="getPattern()"
 required>

And in the controller:

//Escape the special chars
    $scope.getPattern = function(){
        return $scope.user.password && 
              $scope.user.password.replace(/([.*+?^${}()|\[\]\/\\])/g, '\\$1');
    }

It's as simple as the one below, and works like a charm.

My solution perfectly answers your question: How to make JQuery-AJAX request synchronous

Set ajax to synchronous before the ajax call, and then reset it after your ajax call:

$.ajaxSetup({async: false});

$ajax({ajax call....});

$.ajaxSetup({async: true});

In your case it would look like this:

$.ajaxSetup({async: false});

$.ajax({
        type: "POST",
        async: "false",
        url: "checkpass.php",
        data: "password="+password,
        success: function(html) {
            var arr=$.parseJSON(html);
            if(arr == "Successful") {
                return true;
            } else {
                return false;
            }
        }
    });


$.ajaxSetup({async: true});

I hope it helps :)

Simpler with the aggregate function string_agg() (Postgres 9.0 or later):

SELECT movie, string_agg(actor, ', ') AS actor_list
FROM   tbl
GROUP  BY 1;

The 1 in GROUP BY 1 is a positional reference and a shortcut for GROUP BY movie in this case.

string_agg() expects data type text as input. Other types need to be cast explicitly (actor::text) - unless an implicit cast to text is defined - which is the case for all other character types (varchar, character, "char"), and some other types.

As isapir commented, you can add an ORDER BY clause in the aggregate call to get a sorted list - should you need that. Like:

SELECT movie, string_agg(actor, ', ' ORDER BY actor) AS actor_list
FROM   tbl
GROUP  BY 1;

But it's typically faster to sort rows in a subquery. See:

• Postgres SQL - Create Array in Select

on Windows I have python 3.7 installed and I still couldn't activate virtualenv from Gitbash with ./Scripts/activate although it worked from Powershell after running Set-ExecutionPolicy Unrestricted in Powershell and changing the setting to "Yes To All".

I don't like Powershell and I like to use Gitbash, so to activate virtualenv in Gitbash first navigate to your project folder, use ls to list the contents of the folder and be sure you see "Scripts". Change directory to "Scripts" using cd Scripts, once you're in the "Scripts" path use . activate to activate virtualenv. Don't forget the space after the dot.

if only the key column is the same in both tables then try using the following way (Approach 1):

left. join(right , 'key', 'inner')

rather than below(approach 2):

left. join(right , left.key == right.key, 'inner')

Pros of using approach 1:

• the 'key' will show only once in the final dataframe
• easy to use the syntax

Cons of using approach 1:

• only help with the key column
• Scenarios, wherein case of left join, if planning to use the right key null count, this will not work. In that case, one has to rename one of the key as mentioned above.

First globally declare

Context mContext;

pass context with the constructor, by modifying it.

public FeedAdapter(List<Post> myDataset, Context context) {
    mDataset = myDataset;
    this.mContext = context;
}

then use the mContext whereever you need it

In curl version 7.22.0 on Ubuntu and 7.24.0 on OSX the solution to not show progress but to show errors is to use both -s (--silent) and -S (--show-error) like so:

curl -sS http://google.com > temp.html

This works for both redirected output > /some/file, piped output | less and outputting directly to the terminal for me.

Update: Since curl 7.67.0 there is a new option --no-progress-meter which does precisely this and nothing else, see clonejo's answer for more details.

You can use collect method to add list of integers.

List<Integer> list = Arrays.asList(2, 4, 5, 6);
int sum = list.stream().collect(Collectors.summingInt(Integer::intValue));

Add your library folder in your root location of your project and copy all the library files there. For ex YourProject/library then sync it and rest things seems OK to me.

The standalone declaration is a way of telling the parser to ignore any markup declarations in the DTD. The DTD is thereafter used for validation only.

As an example, consider the humble <img> tag. If you look at the XHTML 1.0 DTD, you see a markup declaration telling the parser that <img> tags must be EMPTY and possess src and alt attributes. When a browser is going through an XHTML 1.0 document and finds an <img> tag, it should notice that the DTD requires src and alt attributes and add them if they are not present. It will also self-close the <img> tag since it is supposed to be EMPTY. This is what the XML specification means by "markup declarations can affect the content of the document." You can then use the standalone declaration to tell the parser to ignore these rules.

Whether or not your parser actually does this is another question, but a standards-compliant validating parser (like a browser) should.

Note that if you do not specify a DTD, then the standalone declaration "has no meaning," so there's no reason to use it unless you also specify a DTD.

I faced the issue with my web application based on Spring 3 and deployed on Weblogic 10.3 on Oracle Linux 6. The solution mentioned at the link did not work for me.

I had to take the following steps - 1. Copy the Arial*.ttf font files to JROCKIT_JAVA_HOME/jre/lib/fonts directory 2. Make entries of the fonts in fontconfig.properties.src 3. Restart the cluster from Weblogic console

filename.Arial=Arial.ttf
filename.Arial_Bold=Arial_Bold.ttf
filename.Arial_Italic=Arial_Italic.ttf
filename.Arial_Bold_Italic=Arial_Bold_Italic.ttf

If you need just to execute your VLC playback process and only give control back to your application process when it is done and nothing more complex, then i suppose you can use just:

system("The same thing you type into console");

//My Form
<form id="someform">
        <div class="input-group">
            <textarea placeholder="Post your Comment Here ..." name="post" class="form-control custom-control" rows="3" style="resize:none"></textarea> 
            <span class="input-group-addon">                                            
                <button type="submit" name="post_comment" class="btn btn-primary">
                    Post
                </button>
            </span>
        </div>
    </form>

//your text area get value to URL
<?php
        if(isset($_POST['post_comment']))
        {
            echo htmlspecialchars($_POST['post']);
        }

    ?>

//print the value using get
echo $_GET['post'];

//url must be like this
http://localhost/blog/home.php?post=asdasdsad&post_comment=

//post value has asdasdsad so it will print to your page

This solution is the most complete. It takes in consideration: UINavigationController UIPageViewController UITabBarController And the topmost presented view controller from the top view controller

The example is in Swift 3.

There are 3 overloads

//Get the topmost view controller for the current application.
public func MGGetTopMostViewController() -> UIViewController?  {

    if let currentWindow:UIWindow = UIApplication.shared.keyWindow {
        return MGGetTopMostViewController(fromWindow: currentWindow)
    }

    return nil
}

//Gets the topmost view controller from a specific window.
public func MGGetTopMostViewController(fromWindow window:UIWindow) -> UIViewController? {

    if let rootViewController:UIViewController = window.rootViewController
    {
        return MGGetTopMostViewController(fromViewController:  rootViewController)
    }

    return nil
}


//Gets the topmost view controller starting from a specific UIViewController
//Pass the rootViewController into this to get the apps top most view controller
public func MGGetTopMostViewController(fromViewController viewController:UIViewController) -> UIViewController {

    //UINavigationController
    if let navigationViewController:UINavigationController = viewController as? UINavigationController {
        let viewControllers:[UIViewController] = navigationViewController.viewControllers
        if navigationViewController.viewControllers.count >= 1 {
            return MGGetTopMostViewController(fromViewController: viewControllers[viewControllers.count - 1])
        }
    }

    //UIPageViewController
    if let pageViewController:UIPageViewController = viewController as? UIPageViewController {
        if let viewControllers:[UIViewController] = pageViewController.viewControllers {
            if viewControllers.count >= 1 {
                return MGGetTopMostViewController(fromViewController: viewControllers[0])
            }
        }
    }

    //UITabViewController
    if let tabBarController:UITabBarController = viewController as? UITabBarController {
        if let selectedViewController:UIViewController = tabBarController.selectedViewController {
            return MGGetTopMostViewController(fromViewController: selectedViewController)
        }
    }

    //Lastly, Attempt to get the topmost presented view controller
    var presentedViewController:UIViewController! = viewController.presentedViewController
    var nextPresentedViewController:UIViewController! = presentedViewController?.presentedViewController

    //If there is a presented view controller, get the top most prensentedViewController and return it.
    if presentedViewController != nil {
        while nextPresentedViewController != nil {

            //Set the presented view controller as the next one.
            presentedViewController = nextPresentedViewController

            //Attempt to get the next presented view controller
            nextPresentedViewController = presentedViewController.presentedViewController
        }
        return presentedViewController
    }

    //If there is no topmost presented view controller, return the view controller itself.
    return viewController
}

In your action you need first to load companies like so :

$companies = App\Company::all();
return view('listing.company')->with('companies' => $companies)->render();

This will make the companies variable available in the view, and it should render the HTML correctly.

Try to use postman chrome extension to debug your view.

Generate a different random number each time, not the same one six times in a row.

Use case scenario

I likened Predictability's problem to a bag of six bits of paper, each with a value from 0 to 5 written on it. A piece of paper is drawn from the bag each time a new value is required. If the bag is empty, then the numbers are put back into the bag.

...from this, I can create an algorithm of sorts.

Algorithm

A bag is usually a Collection. I chose a bool[] (otherwise known as a boolean array, bit plane or bit map) to take the role of the bag.

The reason I chose a bool[] is because the index of each item is already the value of each piece of paper. If the papers required anything else written on them then I would have used a Dictionary<string, bool> in its place. The boolean value is used to keep track of whether the number has been drawn yet or not.

A counter called RemainingNumberCount is initialised to 5 that counts down as a random number is chosen. This saves us from having to count how many pieces of paper are left each time we wish to draw a new number.

To select the next random value I'm using a for..loop to scan through the bag of indexes, and a counter to count off when an index is false called NumberOfMoves.

NumberOfMoves is used to choose the next available number. NumberOfMoves is first set to be a random value between 0 and 5, because there are 0..5 available steps we can make through the bag. On the next iteration NumberOfMoves is set to be a random value between 0 and 4, because there are now 0..4 steps we can make through the bag. As the numbers are used, the available numbers reduce so we instead use rand() % (RemainingNumberCount + 1) to calculate the next value for NumberOfMoves.

When the NumberOfMoves counter reaches zero, the for..loop should as follows:

1. Set the current Value to be the same as for..loop's index.
2. Set all the numbers in the bag to false.
3. Break from the for..loop.

Code

The code for the above solution is as follows:

(put the following three blocks into the main .cpp file one after the other)

#include "stdafx.h"
#include <ctime> 
#include <iostream>
#include <string>

class RandomBag {
public:
    int Value = -1;

    RandomBag() {
        ResetBag();

    }

    void NextValue() {
        int BagOfNumbersLength = sizeof(BagOfNumbers) / sizeof(*BagOfNumbers);

        int NumberOfMoves = rand() % (RemainingNumberCount + 1);

        for (int i = 0; i < BagOfNumbersLength; i++)            
            if (BagOfNumbers[i] == 0) {
                NumberOfMoves--;

                if (NumberOfMoves == -1)
                {
                    Value = i;

                    BagOfNumbers[i] = 1;

                    break;

                }

            }



        if (RemainingNumberCount == 0) {
            RemainingNumberCount = 5;

            ResetBag();

        }
        else            
            RemainingNumberCount--; 

    }

    std::string ToString() {
        return std::to_string(Value);

    }

private:
    bool BagOfNumbers[6]; 

    int RemainingNumberCount;

    int NumberOfMoves;

    void ResetBag() {
        RemainingNumberCount = 5;

        NumberOfMoves = rand() % 6;

        int BagOfNumbersLength = sizeof(BagOfNumbers) / sizeof(*BagOfNumbers);

        for (int i = 0; i < BagOfNumbersLength; i++)            
            BagOfNumbers[i] = 0;

    }

};

A Console class

I create this Console class because it makes it easy to redirect output.

Below in the code...

Console::WriteLine("The next value is " + randomBag.ToString());

...can be replaced by...

std::cout << "The next value is " + randomBag.ToString() << std::endl; 

...and then this Console class can be deleted if desired.

class Console {
public:
    static void WriteLine(std::string s) {
        std::cout << s << std::endl;

    }

};

Main method

Example usage as follows:

int main() {
    srand((unsigned)time(0)); // Initialise random seed based on current time

    RandomBag randomBag;

    Console::WriteLine("First set of six...\n");

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    Console::WriteLine("\nSecond set of six...\n");

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    Console::WriteLine("\nThird set of six...\n");

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    randomBag.NextValue();

    Console::WriteLine("The next value is " + randomBag.ToString());

    Console::WriteLine("\nProcess complete.\n");

    system("pause");

}

Example output

When I ran the program, I got the following output:

First set of six...

The next value is 2
The next value is 3
The next value is 4
The next value is 5
The next value is 0
The next value is 1

Second set of six...

The next value is 3
The next value is 4
The next value is 2
The next value is 0
The next value is 1
The next value is 5

Third set of six...

The next value is 4
The next value is 5
The next value is 2
The next value is 0
The next value is 3
The next value is 1

Process complete.

Closing statement

This program was written using Visual Studio 2017, and I chose to make it a Visual C++ Windows Console Application project using .Net 4.6.1.

I'm not doing anything particularly special here, so the code should work on earlier versions of Visual Studio too.

It was my own stupidity:

java.text.DateFormat dateFormat = android.text.format.DateFormat.getDateFormat(getApplicationContext());

Putting this inside onCreate() method fixed my problem.

do tab, then the + sign, then space, then your content

So

* level one + level two tabbed

If you are using Java, you can actually use commons-codec library

import org.apache.commons.codec.binary.Base64;

String stringToBeChecked = "...";
boolean isBase64 = Base64.isArrayByteBase64(stringToBeChecked.getBytes());

[UPDATE 1] Deprecation Notice Use instead

Base64.isBase64(value);

   /**
     * Tests a given byte array to see if it contains only valid characters within the Base64 alphabet. Currently the
     * method treats whitespace as valid.
     *
     * @param arrayOctet
     *            byte array to test
     * @return {@code true} if all bytes are valid characters in the Base64 alphabet or if the byte array is empty;
     *         {@code false}, otherwise
     * @deprecated 1.5 Use {@link #isBase64(byte[])}, will be removed in 2.0.
     */
    @Deprecated
    public static boolean isArrayByteBase64(final byte[] arrayOctet) {
        return isBase64(arrayOctet);
    }

You could call it just style, but I prefer aliasing to improve readability.

You don't need to add '.' in your class name. This will do

document.getElementsByClassName('col1')

Additionally, since you haven't define the background color via javascript, you won't able to call it directly. You have to use window.getComputedStyle() or jquery to achieve what you are trying to do above.

Here is a working example

http://jsfiddle.net/J9LU8/

To add one day to a date object:

var date = new Date();

// add a day
date.setDate(date.getDate() + 1);

By default, all paths you define will be relative. The question is: relative to what? There are several options:

1. Specifying a file or a path with nothing before it. For example: "mylib.lib". In that case, the file will be searched at the Output Directory.
2. If you add "..\", the path will be calculated from the actual path where the .sln file resides.

Please note that following a macro such as $(SolutionDir) there is no need to add a backward slash "\". Just use $(SolutionDir)mylibdir\mylib.lib. In case you just can't get it to work, open the project file externally from Notepad and check it.

I got the solution for the Android Studio installation after trying everything that I could find on the Internet. If you're using Android Studio and getting this error:

Find [Path_to_Android_SDK]\sdk\tools\android.bat. In my case, it was in C:\Users\Nathan\AppData\Local\Android\android-studio\sdk\tools\android.bat.

Right-click it, hit Edit, and scroll all the way down to the bottom.

Find where it says: call %java_exe% %REMOTE_DEBUG% ...

Replace that with call %java_exe% -Djava.net.preferIPv4Stack=true %REMOTE_DEBUG% ...

Restart Android Studio/SDK and everything works. This fixed many issues for me, including being unable to fetch XML files or create new projects.

Note that you must put this in the file ".user.ini" in Centos7 rather than "php.ini" which used to work in Centos6. You can put ".user.ini" in any subdirectory in order to affect only that directory.

.user.ini :

max_input_vars = 3000

Tested on Centos7 and PHP 5.6.33.

I have followed SO questions and answers from each search query. But they all are related with specific one.

At the basic, I mean before you are going to write down a format (may be a simple one) it will gives you a warnings.

From iOS 8.0 by default views are size classes. Even if you disable size classes it will still contains some auto layout constraints.

So if you are planning to set constrains via code using VFL. Then you must take care of one below line.

// Remove constraints if any.
[self.view removeConstraints:self.view.constraints];

I had search a lot in SO, but the solution was lies in Apple Sample Code.

So you must have to remove default constraints before planning to add new one.

In java.util.timer one can use .cancel() to stop the timer and clear all pending tasks.

Have tried many things with respect to scroll, but the below code has provided better results.

This will scroll until the element is in view:

This component takes HTML content and renders it as native views, with customisable style and handling of links, etc.

Dump a table using a where query:

mysqldump mydatabase mytable --where="mycolumn = myvalue" --no-create-info > data.sql

Dump an entire table:

mysqldump mydatabase mytable > data.sql

Notes:

• Replace mydatabase, mytable, and the where statement with your desired values.
• By default, mysqldump will include DROP TABLE and CREATE TABLE statements in its output. Therefore, if you wish to not delete all the data in your table when restoring from the saved data file, make sure you use the --no-create-info option.
• You may need to add the appropriate -h, -u, and -p options to the example commands above in order to specify your desired database host, user, and password, respectively.

Let us say your table has following fields:

( pk_id int not null auto_increment primary key,
  col1 int,
  col2 varchar(10)
)

then, to copy values from one row to the other row with new key value, following query may help

insert into my_table( col1, col2 ) select col1, col2 from my_table where pk_id=?;

This will generate a new value for pk_id field and copy values from col1, and col2 of the selected row.

You can extend this sample to apply for more fields in the table.

UPDATE:
In due respect to the comments from JohnP and Martin -

We can use temporary table to buffer first from main table and use it to copy to main table again. Mere update of pk reference field in temp table will not help as it might already be present in the main table. Instead we can drop the pk field from the temp table and copy all other to the main table.

With reference to the answer by Tim Ruehsen in the referred posting:

CREATE TEMPORARY TABLE tmp SELECT * from my_table WHERE ...;
ALTER TABLE tmp drop pk_id; # drop autoincrement field
# UPDATE tmp SET ...; # just needed to change other unique keys
INSERT INTO my_table SELECT 0,tmp.* FROM tmp;
DROP TEMPORARY TABLE tmp;

Hope this helps.

Using Commons Lang (to convert) + Collections (to min/max)

import java.util.Arrays;
import java.util.Collections;

import org.apache.commons.lang.ArrayUtils;

public class MinMaxValue {

    public static void main(String[] args) {
        char[] a = {'3', '5', '1', '4', '2'};

        List b = Arrays.asList(ArrayUtils.toObject(a));

        System.out.println(Collections.min(b));
        System.out.println(Collections.max(b));
   }
}

Note that Arrays.asList() wraps the underlying array, so it should not be too memory intensive and it should not perform a copy on the elements of the array.

Simply run:

sudo apt-get install default-jdk

The cause of this problem for me was having the wrong build variant selected for one of my app's modules. From the "Build Variants" tool, I selected the module variant which matched the app module, and it fixed the issue for me.

Use the 'EntireColumn' property, that's what it is there for. C# snippet, but should give you a good indication of how to do this:

safeAreaLayoutGuide When the view is visible onscreen, this guide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. (In tvOS, the safe area reflects the area not covered the screen's bezel.) If the view is not currently installed in a view hierarchy, or is not yet visible onscreen, the layout guide edges are equal to the edges of the view.

Then to get the height of the red arrow in the screenshot it's:

self.safeAreaLayoutGuide.layoutFrame.size.height

Remember that HTML and XML are two distinct concepts in the tree of markup languages. You can't exactly replace HTML with XML . XML can be viewed as a generalized form of HTML, but even that is imprecise. You mainly use HTML to display data, and XML to carry(or store) the data.

This link is helpful: How to read HTML as XML?

There is of course some apache log files. Search in your apache configuration files for 'Log' keyword, you'll certainly find plenty of them. Depending on your OS and installation places may vary (in a Typical Linux server it would be /var/log/apache2/[access|error].log).

Having a 503 error in Apache usually means the proxied page/service is not available. I assume you're using tomcat and that means tomcat is either not responding to apache (timeout?) or not even available (down? crashed?). So chances are that it's a configuration error in the way to connect apache and tomcat or an application inside tomcat that is not even sending a response for apache.

Sometimes, in production servers, it can as well be that you get too much traffic for the tomcat server, apache handle more request than the proxyied service (tomcat) can accept so the backend became unavailable.

Wrapping can be done in various ways. I'll mention 2 of them:

1.) text wrapping - using white-space property http://www.w3schools.com/cssref/pr_text_white-space.asp

2.) word wrapping - using word-wrap property http://webdesignerwall.com/tutorials/word-wrap-force-text-to-wrap

By the way, in order to work using these 2 approaches, I believe you need to set the "display" property to block of the corresponding span element.

However, as Kirill already mentioned, it's a good idea to think about it for a moment. You're talking about forcing the text into a paragraph. PARAGRAPH. That should ring some bells in your head, shouldn't it? ;)

You should use other variable:

 $m=0; 
 for($n=1; $n<=8; $n++): 
  $n = $n + $m;
  $m++;
  echo '<p>'. $n .'</p>';
 endfor;

I am using the following script to

1. Find all files that match FILTER with SRC_ENCODING
2. Create a backup of them
3. Convert them to DST_ENCODING
4. (optional) Remove the backups

.

#!/bin/bash -xe

SRC_ENCODING="iso-8859-1"
DST_ENCODING="utf-8"
FILTER="*.java"

echo "Find all files that match the encoding $SRC_ENCODING and filter $FILTER"
FOUND_FILES=$(find . -iname "$FILTER" -exec file -i {} \; | grep "$SRC_ENCODING" | grep -Eo '^.*\.java')

for FILE in $FOUND_FILES ; do
    ORIGINAL_FILE="$FILE.$SRC_ENCODING.bkp"
    echo "Backup original file to $ORIGINAL_FILE"
    mv "$FILE" "$ORIGINAL_FILE"

    echo "converting $FILE from $SRC_ENCODING to $DST_ENCODING"
    iconv -f "$SRC_ENCODING" -t "$DST_ENCODING" "$ORIGINAL_FILE" -o "$FILE"
done

echo "Deleting backups"
find . -iname "*.$SRC_ENCODING.bkp" -exec rm {} \;

It breaks semantics, that's all. It works fine, but there may be screen readers or something down the road that won't enjoy processing your HTML if you "break semantics".

Advice in KB and above didn't work for me. I discovered that if one Excel 2007 user (with or without the security update; not sure of exact circumstances that cause this) saves the file, the original error returns.

I discovered that the fastest way to repair the file again is to delete all the VBA code. Save. Then replace the VBA code (copy/paste). Save. Before attempting this, I delete the .EXD files first, because otherwise I get an error on open.

In my case, I cannot upgrade/update all users of my Excel file in various locations. Since the problem comes back after some users save the Excel file, I am going to have to replace the ActiveX control with something else.

Use empty(). It checks for both empty strings and null.

if (!empty($_POST['user'])) {
  // do stuff
}

From the manual:

The following things are considered to be empty:

"" (an empty string)  
0 (0 as an integer)  
0.0 (0 as a float)  
"0" (0 as a string)    
NULL  
FALSE  
array() (an empty array)  
var $var; (a variable declared, but without a value in a class)  

You will get the proxy host and port from your server administrator or support.

After that set up

npm config set http_proxy http://username:[email protected]:itsport npm config set proxy http://username:[email protected]:itsport If there any special character in password try with % urlencode. Eg:- pound(hash) shuold be replaced by %23.

This worked for me...

h1 {
  font-weight: bold;
  color: #fff;
  font-size: 32px;
}

h2 {
  font-weight: bold;
  color: #fff;
  font-size: 24px;
}

Note that after color you can use a word (e.g. white), a hex code (e.g. #fff) or RGB (e.g. rgb(255,255,255)) or RGBA (e.g. rgba(255,255,255,0.3)).

@see is useful for information about related methods/classes in an API. It will produce a link to the referenced method/code on the documentation. Use it when there is related code that might help the user understand how to use the API.

You can't subtract a list from a list.

>>> [3, 7] - [1, 2]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unsupported operand type(s) for -: 'list' and 'list'

Simple way to do it is using numpy:

>>> import numpy as np
>>> np.array([3, 7]) - np.array([1, 2])
array([2, 5])

You can also use list comprehension, but it will require changing code in the function:

>>> [a - b for a, b in zip([3, 7], [1, 2])]
[2, 5]

>>> import numpy as np
>>>
>>> def Naive_Gauss(Array,b):
...     n = len(Array)
...     for column in xrange(n-1):
...         for row in xrange(column+1, n):
...             xmult = Array[row][column] / Array[column][column]
...             Array[row][column] = xmult
...             #print Array[row][col]
...             for col in xrange(0, n):
...                 Array[row][col] = Array[row][col] - xmult*Array[column][col]
...             b[row] = b[row]-xmult*b[column]
...     print Array
...     print b
...     return Array, b  # <--- Without this, the function will return `None`.
...
>>> print Naive_Gauss(np.array([[2,3],[4,5]]),
...                   np.array([[6],[7]]))
[[ 2  3]
 [-2 -1]]
[[ 6]
 [-5]]
(array([[ 2,  3],
       [-2, -1]]), array([[ 6],
       [-5]]))

The project I'm working on, we do something like this. We use the errorlevel keyword so it kind of looks like:

call myExe.exe
if errorlevel 1 (
  goto build_fail
)

That seems to work for us. Note that you can put in multiple commands in the parens like an echo or whatever. Also note that build_fail is defined as:

:build_fail
echo ********** BUILD FAILURE **********
exit /b 1

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

No, nothing like that exists. The extension method is the way to go, and your name for it (GetValueOrDefault) is a pretty good choice.

String actual = list.stream().reduce((t, u) -> t + "," + u).get();

There is an application for both Mac & Windows call Handbrake, i know this isn't command line stuff but for a quick open file - select output file format & rough output size whilst keeping most of the good stuff about the video then this is good, it's a just a graphical view of ffmpeg at its best ... It does support command line input for those die hard texters.. https://handbrake.fr/downloads.php

Use sscanf

/* sscanf example */
#include <stdio.h>

int main ()
{
  char sentence []="Rudolph is 12 years old";
  char str [20];
  int i;

  sscanf (sentence,"%s %*s %d",str,&i);
  printf ("%s -> %d\n",str,i);

  return 0;
}

if you meant comparing nth item with n+1 th item in the list you could also do with

>>> for i in range(len(list[:-1])):
...     print list[i]>list[i+1]

note there is no hard coding going on there. This should be ok unless you feel otherwise.

You can turn autocommit ON by setting implicit_transactions OFF:

SET IMPLICIT_TRANSACTIONS OFF

When the setting is ON, it returns to implicit transaction mode. In implicit transaction mode, every change you make starts a transactions which you have to commit manually.

Maybe an example is clearer. This will write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
COMMIT TRANSACTION

This will not write a change to the database:

SET IMPLICIT_TRANSACTIONS ON
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

The following example will update a row, and then complain that there's no transaction to commit:

SET IMPLICIT_TRANSACTIONS OFF
UPDATE MyTable SET MyField = 1 WHERE MyId = 1
ROLLBACK TRANSACTION

Like Mitch Wheat said, autocommit is the default for Sql Server 2000 and up.

There is actually, a less heavy-handed way of doing a stream copy. Take note however, that this implies that you can store the entire file in memory. Don't try and use this if you are working with files that go into the hundreds of megabytes or more, without caution.

public static void CopySmallTextStream(Stream input, Stream output)
{
  using (StreamReader reader = new StreamReader(input))
  using (StreamWriter writer = new StreamWriter(output))
  {
    writer.Write(reader.ReadToEnd());
  }
}

NOTE: There may also be some issues concerning binary data and character encodings.

if your application accepts errors raise from Oracle, then you can use it. we have an application, each time when an error happens, we call raise_application_error, the application will popup a red box to show the error message we provide through this method.

When using dotnet code, I just use "raise", dotnet exception mechanisim will automatically capture the error passed by Oracle ODP and shown inside my catch exception code.

Using array_search() and unset, try the following:

if (($key = array_search($del_val, $messages)) !== false) {
    unset($messages[$key]);
}

array_search() returns the key of the element it finds, which can be used to remove that element from the original array using unset(). It will return FALSE on failure, however it can return a false-y value on success (your key may be 0 for example), which is why the strict comparison !== operator is used.

The if() statement will check whether array_search() returned a value, and will only perform an action if it did.

An array "decays" into a pointer to its first element, so scanf("%s", string) is equivalent to scanf("%s", &string[0]). On the other hand, scanf("%s", &string) passes a pointer-to-char[256], but it points to the same place.

Then scanf, when processing the tail of its argument list, will try to pull out a char *. That's the Right Thing when you've passed in string or &string[0], but when you've passed in &string you're depending on something that the language standard doesn't guarantee, namely that the pointers &string and &string[0] -- pointers to objects of different types and sizes that start at the same place -- are represented the same way.

I don't believe I've ever encountered a system on which that doesn't work, and in practice you're probably safe. None the less, it's wrong, and it could fail on some platforms. (Hypothetical example: a "debugging" implementation that includes type information with every pointer. I think the C implementation on the Symbolics "Lisp Machines" did something like this.)

If you are already using Qt

QSettings my_settings("filename.ini", QSettings::IniFormat);

Then read a value

my_settings.value("GroupName/ValueName", <<DEFAULT_VAL>>).toInt()

There are a bunch of other converter that convert your INI values into both standard types and Qt types. See Qt documentation on QSettings for more information.

Since the release of iOS 8, UIAlertView is now deprecated; UIAlertController is the replacement.

Here is a sample of how it looks in Swift:

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
let alertAction = UIAlertAction(title: "OK!", style: UIAlertActionStyle.default)
{
    (UIAlertAction) -> Void in
}
alert.addAction(alertAction)
present(alert, animated: true)
{
    () -> Void in
}

As you can see, the API allows us to implement callbacks for both the action and when we are presenting the alert, which is quite handy!

Updated for Swift 4.2

let alert = UIAlertController(title: "Hello!", message: "Message", preferredStyle: .alert)
let alertAction = UIAlertAction(title: "OK!", style: .default)
        {
            (UIAlertAction) -> Void in
        }
        alert.addAction(alertAction)
        present(alert, animated: true)
        {
            () -> Void in
        }

It was written above: in my case it was just out of memory on device storage. Add more empty space - and error will disappear

I found slightly different problem running R on through mac terminal, but connecting remotely to an Ubuntu server, which prevented me from successfully installing a library.

The solution I have was finding out what "LANG" variable is used in Ubuntu terminal

Ubuntu > echo $LANG
en_US.TUF-8

I got "en_US.TUF-8" reply from Ubuntu.

In R session, however, I got "UTF-8" as the default value and it complained that LC_TYPEC Setting LC_CTYPE failed, using "C"

R> Sys.getenv("LANG")
"UTF-8"

So, I tried to change this variable in R. It worked.

R> Sys.setenv(LANG="en_US.UTF-8")

Do not use Mockito.anyXXXX(). Directly pass the value to the method parameter of same type. Example:

A expected = new A(10);

String firstId = "10w";
String secondId = "20s";
String product = "Test";
String type = "type2";
Mockito.when(service.getTestData(firstId, secondId, product,type)).thenReturn(expected);

public class A{
   int a ;
   public A(int a) {
      this.a = a;
   }
}

you can also try this in sql-server !!

select a.city,a.total + b.total as mytotal from [dbo].[cash] a join [dbo].[cheque] b on a.city=b.city

or try using sum,union

select sum(total)  as mytotal,city
from

    select * from cheque
) as vij

Modules are fine for storing enums and some global variables, constants and shared functions. its very good thing and I often use it. Declared variables are visible acros entire project.

In my experience it's been a convention thing. I'm not aware of any technical reason to use int over Int32, but it's:

1. Quicker to type.
2. More familiar to the typical C# developer.
3. A different color in the default visual studio syntax highlighting.

I'm especially fond of that last one. :)

You can use T-SQL to convert the date before it gets to your .NET program. This often is simpler if you don't need to do additional date conversion in your .NET program.

DECLARE @Date DATETIME = Getdate()
DECLARE @DateInt INT = CONVERT(VARCHAR(30), @Date, 112)
DECLARE @TimeInt INT = REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
DECLARE @DateTimeInt BIGINT = CONVERT(VARCHAR(30), @Date, 112) + REPLACE(CONVERT(VARCHAR(30), @Date, 108), ':', '')
SELECT @Date as Date, @DateInt DateInt, @TimeInt TimeInt, @DateTimeInt DateTimeInt

Date                    DateInt     TimeInt     DateTimeInt

Here is where I found it on a Windows 2008R2 server. Elevated Task Scheduler Click on "Task Scheduler Library" It appears as an option on the right hand "Actions" panel.

SELECT * FROM (SELECT colA, colB FROM tableA UNION SELECT colA, colB FROM tableB) as tableC WHERE tableC.colA > 1

If we're using a union that contains the same field name in 2 tables, then we need to give a name to the sub query as tableC(in above query). Finally, the WHERE condition should be WHERE tableC.colA > 1

A small note on custom attributes: HTML5 allows all kind of custom attributes, as long as they are prefixed with the particle data-, i.e. data-my-attribute="true".

Others propose that exceptions should not be used because the bad login is to be expected in a normal flow if the user mistypes. I disagree and I don't get the reasoning. Compare it with opening a file.. if the file doesn't exist or is not available for some reason then an exception will be thrown by the framework. Using the logic above this was a mistake by Microsoft. They should have returned an error code. Same for parsing, webrequests, etc., etc..

I don't consider a bad login part of a normal flow, it's exceptional. Normally the user types the correct password, and the file does exist. The exceptional cases are exceptional and it's perfectly fine to use exceptions for those. Complicating your code by propagating return values through n levels up the stack is a waste of energy and will result in messy code. Do the simplest thing that could possibly work. Don't prematurely optimize by using error codes, exceptional stuff by definition rarely happens, and exceptions don't cost anything unless you throw them.

As others have said, std::max_element() and std::min_element() return iterators, which need to be dereferenced to obtain the value.

The advantage of returning an iterator (rather than just the value) is that it allows you to determine the position of the (first) element in the container with the maximum (or minimum) value.

For example (using C++11 for brevity):

#include <vector>
#include <algorithm>
#include <iostream>

int main()
{
    std::vector<double> v {1.0, 2.0, 3.0, 4.0, 5.0, 1.0, 2.0, 3.0, 4.0, 5.0};

    auto biggest = std::max_element(std::begin(v), std::end(v));
    std::cout << "Max element is " << *biggest
        << " at position " << std::distance(std::begin(v), biggest) << std::endl;

    auto smallest = std::min_element(std::begin(v), std::end(v));
    std::cout << "min element is " << *smallest
        << " at position " << std::distance(std::begin(v), smallest) << std::endl;
}

This yields:

Max element is 5 at position 4
min element is 1 at position 0

Note:

Using std::minmax_element() as suggested in the comments above may be faster for large data sets, but may give slightly different results. The values for my example above would be the same, but the position of the "max" element would be 9 since...

If several elements are equivalent to the largest element, the iterator to the last such element is returned.

Well you seem to have mistaken them both for what they do.

$(window).height() gets you an unit-less pixel value of the height of the (browser) window aka viewport. With respect to the web browsers the viewport here is visible portion of the canvas(which often is smaller than the document being rendered).

$(document).height() returns an unit-less pixel value of the height of the document being rendered. However, if the actual document’s body height is less than the viewport height then it will return the viewport height instead.

Hope that clears things a little.

Wrap your formula with IFERROR.

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

You can also use the setProperty method like below

document.getElementById('divName').style.setProperty("top", "100px");

Andrey Tarasevich provides the following explanation:

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

I dont know why you havent marked on of these gr8 answers... here is another option which would enable you and anyone else visiting to control transition speed and pause time

JAVASCRIPT

$(function () {

    /* SET PARAMETERS */
    var change_img_time     = 5000; 
    var transition_speed    = 100;

    var simple_slideshow    = $("#exampleSlider"),
        listItems           = simple_slideshow.children('li'),
        listLen             = listItems.length,
        i                   = 0,

        changeList = function () {

            listItems.eq(i).fadeOut(transition_speed, function () {
                i += 1;
                if (i === listLen) {
                    i = 0;
                }
                listItems.eq(i).fadeIn(transition_speed);
            });

        };

    listItems.not(':first').hide();
    setInterval(changeList, change_img_time);

});

This is a circular dependency issue. Golang programs must be acyclic. In Golang cyclic imports are not allowed (That is its import graph must not contain any loops)

Lets say your project go-circular-dependency have 2 packages "package one" & it has "one.go" & "package two" & it has "two.go" So your project structure is as follows

+--go-circular-dependency    
      +--one    
         +-one.go
      +--two        
         +-two.go

This issue occurs when you try to do something like following.

Step 1 - In one.go you import package two (Following is one.go)

package one

import (
    "go-circular-dependency/two"
)

//AddOne is
func AddOne() int {
    a := two.Multiplier()
    return a + 1
}

Step 2 - In two.go you import package one (Following is two.go)

package two

import (
    "fmt"
    "go-circular-dependency/one"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    //import AddOne from "package one"
    x := one.AddOne()
    fmt.Println(x)
}

In Step 2, you will receive an error "can't load package: import cycle not allowed" (This is called "Circular Dependency" error)

Technically speaking this is bad design decision and you should avoid this as much as possible, but you can "Break Circular Dependencies via implicit interfaces" (I personally don't recommend, and highly discourage this practise, because by design Go programs must be acyclic)

Try to keep your import dependency shallow. When the dependency graph becomes deeper (i.e package x imports y, y imports z, z imports x) then circular dependencies become more likely.

Sometimes code repetition is not bad idea, which is exactly opposite of DRY (don't repeat yourself)

So in Step 2 that is in two.go you should not import package one. Instead in two.go you should actually replicate the functionality of AddOne() written in one.go as follows.

package two

import (
    "fmt"
)

//Multiplier is going to be used in package one
func Multiplier() int {
    return 2
}

//Total is
func Total() {
    // x := one.AddOne()
    x := Multiplier() + 1
    fmt.Println(x)
}

An array is a pointer. It points to the start of a sequence of "objects".

If we do this: ìnt arr[10];, then arr is a pointer to a memory location, from which ten integers follow. They are uninitialised, but the memory is allocated. It is exactly the same as doing int *arr = new int[10];.

As Kris mentions, you can use the $resource service to interact with the server, but I get the impression you are beginning your journey with Angular - I was there last week - so I recommend to start experimenting directly with the $http service. In this case you can call its get method.

If you have the following JSON

[{ "text":"learn angular", "done":true },
 { "text":"build an angular app", "done":false},
 { "text":"something", "done":false },
 { "text":"another todo", "done":true }]

You can load it like this

var App = angular.module('App', []);

App.controller('TodoCtrl', function($scope, $http) {
  $http.get('todos.json')
       .then(function(res){
          $scope.todos = res.data;                
        });
});

The get method returns a promise object which first argument is a success callback and the second an error callback.

When you add $http as a parameter of a function Angular does it magic and injects the $http resource into your controller.

I've put some examples here

• http://plnkr.co/edit/Wuc6M7?p=preview
• https://gist.github.com/3938567

you would need to first open your file in read format, save it to a variable, then open the second file in write format where you would write or append the variable using a the [::-1] slice, completely reversing the file. You can also use readlines() to make it into a list of lines, which you can manipulate

def copy_and_reverse(filename, newfile):
    with open(filename) as file:
        text = file.read()
    with open(newfile, "w") as file2:
        file2.write(text[::-1])

jQuery

jQuery makes ridiculously long JavaScript commands like getElementByHerpDerp shorter and cross-browser.

AngularJS

AngularJS allows you to make your own HTML tags/attributes that do things which work well with dynamic web applications (since HTML was designed for static pages).

Edit:

Saying "I have a jQuery background how do I think in AngularJS?" is like saying "I have an HTML background how do I think in JavaScript?" The fact that you're asking the question shows you most likely don't understand the fundamental purposes of these two resources. This is why I chose to answer the question by simply pointing out the fundamental difference rather than going through the list saying "AngularJS makes use of directives whereas jQuery uses CSS selectors to make a jQuery object which does this and that etc....". This question does not require a lengthy answer.

jQuery is a way to make programming JavaScript in the browser easier. Shorter, cross-browser commands, etc.

AngularJS extends HTML, so you don't have to put <div> all over the place just to make an application. It makes HTML actually work for applications rather than what it was designed for, which is static, educational web pages. It accomplishes this in a roundabout way using JavaScript, but fundamentally it is an extension of HTML, not JavaScript.

If you ever need to send GET request to an IP as well as a Domain (Other answers did not mention you can specify a port variable), you can make use of this function:

function getCode(host, port, path, queryString) {
    console.log("(" + host + ":" + port + path + ")" + "Running httpHelper.getCode()")

    // Construct url and query string
    const requestUrl = url.parse(url.format({
        protocol: 'http',
        hostname: host,
        pathname: path,
        port: port,
        query: queryString
    }));

    console.log("(" + host + path + ")" + "Sending GET request")
    // Send request
    console.log(url.format(requestUrl))
    http.get(url.format(requestUrl), (resp) => {
        let data = '';

        // A chunk of data has been received.
        resp.on('data', (chunk) => {
            console.log("GET chunk: " + chunk);
            data += chunk;
        });

        // The whole response has been received. Print out the result.
        resp.on('end', () => {
            console.log("GET end of response: " + data);
        });

    }).on("error", (err) => {
        console.log("GET Error: " + err);
    });
}

Don't miss requiring modules at the top of your file:

http = require("http");
url = require('url')

Also bare in mind that you may use https module for communicating over secured network.

I was having similar problem but I came out of the solution the problem was that you were using any thing in the dependency that correspond to same domain but with different versions make sure those all are same

You'll likely need to check the SQL Server error logs to determine the actual state (it's not reported to the client for security reasons.) See here for details.

Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.

Try using this command to allow a port

sudo ufw allow 1701

To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:

nc -l 1701

Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.

I would prefer to keep the "Show Whitespace" button on the toolbar, so that in one click you can toggle it.

Go to Window -> Perspective -> Customize Perspective and enable to show the button on toolbar.

There is no DrawCircle method; use DrawEllipse instead. I have a static class with handy graphics extension methods. The following ones draw and fill circles. They are wrappers around DrawEllipse and FillEllipse:

public static class GraphicsExtensions
{
    public static void DrawCircle(this Graphics g, Pen pen,
                                  float centerX, float centerY, float radius)
    {
        g.DrawEllipse(pen, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }

    public static void FillCircle(this Graphics g, Brush brush,
                                  float centerX, float centerY, float radius)
    {
        g.FillEllipse(brush, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }
}

You can call them like this:

g.FillCircle(myBrush, centerX, centerY, radius);
g.DrawCircle(myPen, centerX, centerY, radius);

The format of the date value is 'YYYY-MM-DD'. See the following example

<form>
<input value="2015-11-30" name='birthdate' type='date' class="form-control" placeholder="Date de naissance"/>
</form>

All you need is to format the date in php, asp, ruby or whatever to have that format.

Apologies in advance for this lo-tech suggestion, but another option, which finally worked for me after battling NuGet for several hours, is to re-create a new empty project, Web API in my case, and just copy the guts of your old, now-broken project into the new one. Took me about 15 minutes.

Actually you're close to your goal, you just need to use nodes() method to split your rows and then get values:

select
    s.SqmId,
    m.c.value('@id', 'varchar(max)') as id,
    m.c.value('@type', 'varchar(max)') as type,
    m.c.value('@unit', 'varchar(max)') as unit,
    m.c.value('@sum', 'varchar(max)') as [sum],
    m.c.value('@count', 'varchar(max)') as [count],
    m.c.value('@minValue', 'varchar(max)') as minValue,
    m.c.value('@maxValue', 'varchar(max)') as maxValue,
    m.c.value('.', 'nvarchar(max)') as Value,
    m.c.value('(text())[1]', 'nvarchar(max)') as Value2
from sqm as s
    outer apply s.data.nodes('Sqm/Metrics/Metric') as m(c)

If you are using Eclipse you can move files to and from the SD Card through the Android Perspective (it is called DDMS in Eclipse). Just select the Emulator in the left part of the screen and then choose the File Explorer tab. Above the list with your files should be two symbols, one with an arrow pointing at a phone, clicking this will allow you to choose a file to move to phone memory.

Try to pass value a and compare using the equals method like this:

public static void main(String str[]) {

    boolean b = str[0].equals("a");

    System.out.println(b);

}

Follow this link to know more about Command line argument in Java

Try

1) apt-get install libmagickwand-dev

2) gem install rmagick

with a little help of math

#include <math.h>
int main(){
  int a = -1;
  unsigned int b;
  b = abs(a);
}

Being forced to have only 1 return statement at the end of a method and making the code fall down to that.

Also not being able to re-use case statements in a switch and let it drop through; I had to write a convoluted script that did a sort of loop of the switch to handle both cases in the right order.

Lastly, when I started using C, I found it very odd to declare my variables at the top of a method and absolutely hated it. I'd spent a good couple of years in C++ and just declared them wherever I wanted; Unless for optimisation reasons I now declare all method variables at the top of a method with details of what they all do - makes maintenance A LOT easier.
