Here is a simple example I wrote to convert and convert back using the 2 convert methods, I also checked it with a fixed string

declare @VB1 VARBINARY(500),@VB2 VARBINARY(500),@VB3 VARBINARY(500)

declare @S1 VARCHAR(500)

SET @VB1=HASHBYTES('SHA1','Test')

SET @S1=CONVERT(varchar(500),@VB1,2)

SET @VB2=CONVERT(varbinary(500),@S1,2)

SET @VB3=CONVERT(varbinary(500),'640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA',2)

SELECT @VB1,@S1,@VB2,@VB3

IF @VB1=@VB2 PRINT 'They Match(2)'

IF @VB1=@VB3 PRINT 'They Match(3)'

PRINT str(Len(@VB1))

PRINT str(Len(@S1))

PRINT str(Len(@VB2))

SET @VB1=HASHBYTES('SHA1','Test')

SET @S1=CONVERT(varchar(500),@VB1,1)

SET @VB2=CONVERT(varbinary(500),@S1,1)

SELECT @VB1,@S1,@VB2

IF @VB1=@VB2 PRINT 'They Match(1)'

PRINT str(Len(@VB1))

PRINT str(Len(@S1))

PRINT str(Len(@VB2))

and the output

||| 0x640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA|640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA|0x640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA|0x640AB2BAE07BEDC4C163F679A746F7AB7FB5D1FA

It seems to be working fine:

List<BigDecimal> list = Arrays.asList(new BigDecimal("24.455"), new BigDecimal("23.455"), new BigDecimal("28.455"), new BigDecimal("20.455"));
System.out.println("Unsorted list: " + list);
final List<BigDecimal> sortedList = list.stream().sorted((o1, o2) -> o1.compareTo(o2)).collect(Collectors.toList());
System.out.println("Sorted list: " + sortedList);

Example Input/Output

Unsorted list: [24.455, 23.455, 28.455, 20.455]
Sorted list: [20.455, 23.455, 24.455, 28.455]

Are you sure you are not verifying list instead of sortedList [in above example] i.e. you are storing the result of stream() in a new List object and verifying that object?

You could try computing sin(pi/2) (or cos(pi/2) for that matter) using the (fairly) quickly converging power series for sin and cos. (Even better: use various doubling formulas to compute nearer x=0 for faster convergence.)

BTW, better than using series for tan(x) is, with computing say cos(x) as a black box (e.g. you could use taylor series as above) is to do root finding via Newton. There certainly are better algorithms out there, but if you don't want to verify tons of digits this should suffice (and it's not that tricky to implement, and you only need a bit of calculus to understand why it works.)

MSYS has not been updated a long time, MSYS2 is more active, you can download from MSYS2, it has both mingw and cygwin fork package.

To install the MinGW-w64 toolchain (Reference):

1. Open MSYS2 shell from start menu
2. Run pacman -Sy pacman to update the package database
3. Re-open the shell, run pacman -Syu to update the package database and core system packages
4. Re-open the shell, run pacman -Su to update the rest
5. Install compiler:
   • For 32-bit target, run pacman -S mingw-w64-i686-toolchain
   • For 64-bit target, run pacman -S mingw-w64-x86_64-toolchain
6. Select which package to install, default is all
7. You may also need make, run pacman -S make

A function call needs to be performed with objects. You are doing the equivalent of this:

// function declaration/definition
void foo(int) {}

// function call
foo(int); // wat!??

i.e. passing a type where an object is required. This makes no sense in C or C++. You need to be doing

int i = 42;
foo(i);

or

foo(42);

I always use the following code to make it work. There are some notes:

1. If you place image URL before gradient, this image will be displayed above the gradient as expected.

This technique is just the same as we have multiple background images as describe here

You need to give a relative file path of <a href="../index.html">Home</a>

Alternately you can specify a link from the root of your site with <a href="/pages/en/index.html">Home</a>

.. and . have special meanings in file paths, .. means up one directory and . means current directory.

so <a href="index.html">Home</a> is the same as <a href="./index.html">Home</a>

For Python 3xx:

import time
for i in range(10):
    time.sleep(0.2) 
    print ("\r Loading... {}".format(i)+str(i), end="")

usually i don't use for loop in R, but here is my solution using for loops and two packages : plyr and dostats

plyr is on cran and you can download dostats on https://github.com/halpo/dostats (may be using install_github from Hadley devtools package)

Assuming that i have your first two data.frame (Df.1 and Df.2) in csv files, you can do something like this.

require(plyr)
require(dostats)

files <- list.files(pattern = ".csv")


for (i in seq_along(files)) {

    assign(paste("Df", i, sep = "."), read.csv(files[i]))

    assign(paste(paste("Df", i, sep = ""), "summary", sep = "."), 
           ldply(get(paste("Df", i, sep = ".")), dostats, sum, min, mean, median, max))

}

Here is the output

R> Df1.summary
  .id sum min   mean median max
1   A  34   4 5.6667    5.5   8
2   B  22   1 3.6667    3.0   9
R> Df2.summary
  .id sum min   mean median max
1   A  21   1 3.5000    3.5   6
2   B  16   1 2.6667    2.5   5

GET /user?name=bob

{
    "name": "$input.params().querystring.get('name')"
}

GET /user/bob

{
    "name": "$input.params('name')"
}

If you have WHM available it is easier.

Log in to WHM.

Go to EasyApache 4 (or whatever version u have) under Software tab.

Under Currently Installed Packages click Customize.

Go to PHP Extensions, in search type "zip" (without quotes),

you should see 3 modules

check all of them,

click blue button few times to finish the process.

This worked for me. Thankfully I've WHM available.

If anyone is interested, you can have the the offset information for all the consumer groups with the following command:

kafka-consumer-groups --bootstrap-server localhost:9092 --all-groups --describe

The parameter --all-groups is available from Kafka 2.4.0

I know question is specific to MVC4. But since we are way past MVC4 and if anyone looking for ASP.NET Core, you can use:

<partial name="_My_Partial" model="Model.MyInfo" />

Because this is a frequent viewed question, I want to mention that a PowerShell function should use approved verbs (Verb-Noun as the function name). The verb part of the name identifies the action that the cmdlet performs. The noun part of the name identifies the entity on which the action is performed. This rule simplifies the usage of your cmdlets for advanced PowerShell users.

Also, you can specify things like whether the parameter is mandatory and the position of the parameter:

function Test-Script
{
    [CmdletBinding()]
    Param
    (
        [Parameter(Mandatory=$true, Position=0)]
        [string]$arg1,

        [Parameter(Mandatory=$true, Position=1)]
        [string]$arg2
    )

    Write-Host "`$arg1 value: $arg1"
    Write-Host "`$arg2 value: $arg2"
}

To pass the parameter to the function you can either use the position:

Test-Script "Hello" "World"

Or you specify the parameter name:

Test-Script -arg1 "Hello" -arg2 "World"

You don't use parentheses like you do when you call a function within C#.

I would recommend to always pass the parameter names when using more than one parameter, since this is more readable.

Create array with all markers on add in map.

Later, use:

Marker temp = markers.get(markers.size() - 1);
temp.remove();

"Allocation Failure" is cause of GC to kick is not correct. It is an outcome of GC operation.

GC kicks in when there is no space to allocate( depending on region minor or major GC is performed). Once GC is performed if space is freed good enough, but if there is not enough size it fails. Allocation Failure is one such failure. Below document have good explanation https://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/g1_gc.html

You can use std::map::at member function, it returns a reference to the mapped value of the element identified with key k.

std::map<char,int> mymap = {
                               { 'a', 0 },
                               { 'b', 0 },
                           };

  mymap.at('a') = 10;
  mymap.at('b') = 20;

Not something completely different, just a bit rewritten recipe from Cookbook. It's futhermore optimized by retaining setdefault method, instead of each time getting it through the instance:

def inverse(mapping):
    '''
    A function to inverse mapping, collecting keys with simillar values
    in list. Careful to retain original type and to be fast.
    >> d = dict(a=1, b=2, c=1, d=3, e=2, f=1, g=5, h=2)
    >> inverse(d)
    {1: ['f', 'c', 'a'], 2: ['h', 'b', 'e'], 3: ['d'], 5: ['g']}
    '''
    res = {}
    setdef = res.setdefault
    for key, value in mapping.items():
        setdef(value, []).append(key)
    return res if mapping.__class__==dict else mapping.__class__(res)

Designed to be run under CPython 3.x, for 2.x replace mapping.items() with mapping.iteritems()

On my machine runs a bit faster, than other examples here

Common sense works here: os is a module, and os.path is a module, too. So just import the module you want to use:

• If you want to use functionalities in the os module, then import os.

• If you want to use functionalities in the os.path module, then import os.path.

• If you want to use functionalities in both modules, then import both modules:

  import os
  import os.path
  

For reference:

• Lib/idlelib/rpc.py uses os and imports os.

• Lib/idlelib/idle.py uses os.path and imports os.path.

• Lib/ensurepip/init.py uses both and imports both.

Try this:

for (int i = 0; i < [arr count]; i++)
{
    NSString *str1 = [arr objectAtIndex:[arr count]-1];
    [arr insertObject:str1 atIndex:i];
    [arr removeObjectAtIndex:[arr count]-1];
}

A generic solution with a timeout:

import time

def onerror_retry(exception, callback, timeout=2, timedelta=.1):
    end_time = time.time() + timeout
    while True:
        try:
            yield callback()
            break
        except exception:
            if time.time() > end_time:
                raise
            elif timedelta > 0:
                time.sleep(timedelta)

Usage:

for retry in onerror_retry(SomeSpecificException, do_stuff):
    retry()

I made some small changes to Alex McKay's function/usage that I think make it a little easier to follow why it works and also adheres to the no-use-before-define rule.

First, define this function to use:

const getKeyValue = function<T extends object, U extends keyof T> (obj: T, key: U) { return obj[key] }

In the way I've written it, the generic for the function lists the object first, then the property on the object second (these can occur in any order, but if you specify U extends key of T before T extends object you break the no-use-before-define rule, and also it just makes sense to have the object first and its' property second. Finally, I've used the more common function syntax instead of the arrow operators (=>).

Anyways, with those modifications you can just use it like this:

interface User {
  name: string;
  age: number;
}

const user: User = {
  name: "John Smith",
  age: 20
};

getKeyValue(user, "name")

Which, again, I find to be a bit more readable.

You can use the subprocess package with the code as below:

import subprocess
cmdCommand = "python test.py"   #specify your cmd command
process = subprocess.Popen(cmdCommand.split(), stdout=subprocess.PIPE)
output, error = process.communicate()
print output

This appears to be one of the most complicated questions in Android since (as of this writing) Android doesn't have iOS equivalents of applicationDidEnterBackground() or applicationWillEnterForeground() callbacks. I used an AppState Library that was put together by @jenzz.

[AppState is] a simple, reactive Android library based on RxJava that monitors app state changes. It notifies subscribers every time the app goes into background and comes back into foreground.

It turned out this is exactly what I needed, especially because my app had multiple activities so simply checking onStart() or onStop() on an activity wasn't going to cut it.

First I added these dependencies to gradle:

dependencies {
    compile 'com.jenzz.appstate:appstate:3.0.1'
    compile 'com.jenzz.appstate:adapter-rxjava2:3.0.1'
}

Then it was a simple matter of adding these lines to an appropriate place in your code:

//Note that this uses RxJava 2.x adapter. Check the referenced github site for other ways of using observable
Observable<AppState> appState = RxAppStateMonitor.monitor(myApplication);
//where myApplication is a subclass of android.app.Application
appState.subscribe(new Consumer<AppState>() {
    @Override
    public void accept(@io.reactivex.annotations.NonNull AppState appState) throws Exception {
        switch (appState) {
            case FOREGROUND:
                Log.i("info","App entered foreground");
                break;
            case BACKGROUND:
                Log.i("info","App entered background");
                break;
        }
    }
});

Depending on how you subscribe to the observable, you may have to unsubscribe from it to avoid memory leaks. Again more info on the github page.

When I needed HTML to PDF conversion earlier this year, I tried the trial of Winnovative HTML to PDF converter (I think ExpertPDF is the same product, too). It worked great so we bought a license at that company. I don't go into it too in depth after that.

I've tried different ways of blocking scrolling when the arrow keys are pressed, both jQuery and native Javascript - they all work fine in Firefox, but don't work in recent versions of Chrome.
Even the explicit {passive: false} property for window.addEventListener, which is recommended as the only working solution, for example here.

In the end, after many tries, I found a way that works for me in both Firefox and Chrome:

window.addEventListener('keydown', (e) => {
    if (e.target.localName != 'input') {   // if you need to filter <input> elements
        switch (e.keyCode) {
            case 37: // left
            case 39: // right
                e.preventDefault();
                break;
            case 38: // up
            case 40: // down
                e.preventDefault();
                break;
            default:
                break;
        }
    }
}, {
    capture: true,   // this disables arrow key scrolling in modern Chrome
    passive: false   // this is optional, my code works without it
});

Quote for EventTarget.addEventListener() from MDN

options Optional
   An options object specifies characteristics about the event listener. The available options are:

capture
   A Boolean indicating that events of this type will be dispatched to the registered listener before being dispatched to any EventTarget beneath it in the DOM tree.
once
   ...
passive
   A Boolean that, if true, indicates that the function specified by listener will never call preventDefault(). If a passive listener does call preventDefault(), the user agent will do nothing other than generate a console warning. ...

I just want to point out that you can leave off the lines that say

EXCEPTION  
  WHEN OTHERS THEN    
    RAISE;

You'll get the same effect if you leave off the exception block all together, and the line number reported for the exception will be the line where the exception is actually thrown, not the line in the exception block where it was re-raised.

In SQL Server, row-oriented storage both clustered and nonclustered indexes are organized as B trees.

(Image Source)

The key difference between clustered indexes and non clustered indexes is that the leaf level of the clustered index is the table. This has two implications.

1. The rows on the clustered index leaf pages always contain something for each of the (non-sparse) columns in the table (either the value or a pointer to the actual value).
2. The clustered index is the primary copy of a table.

Non clustered indexes can also do point 1 by using the INCLUDE clause (Since SQL Server 2005) to explicitly include all non-key columns but they are secondary representations and there is always another copy of the data around (the table itself).

CREATE TABLE T
(
A INT,
B INT,
C INT,
D INT
)

CREATE UNIQUE CLUSTERED INDEX ci ON T(A, B)
CREATE UNIQUE NONCLUSTERED INDEX nci ON T(A, B) INCLUDE (C, D)

The two indexes above will be nearly identical. With the upper-level index pages containing values for the key columns A, B and the leaf level pages containing A, B, C, D

There can be only one clustered index per table, because the data rows themselves can be sorted in only one order.

The above quote from SQL Server books online causes much confusion

In my opinion, it would be much better phrased as.

There can be only one clustered index per table because the leaf level rows of the clustered index are the table rows.

The book's online quote is not incorrect but you should be clear that the "sorting" of both non clustered and clustered indices is logical, not physical. If you read the pages at leaf level by following the linked list and read the rows on the page in slot array order then you will read the index rows in sorted order but physically the pages may not be sorted. The commonly held belief that with a clustered index the rows are always stored physically on the disk in the same order as the index key is false.

This would be an absurd implementation. For example, if a row is inserted into the middle of a 4GB table SQL Server does not have to copy 2GB of data up in the file to make room for the newly inserted row.

Instead, a page split occurs. Each page at the leaf level of both clustered and non clustered indexes has the address (File: Page) of the next and previous page in logical key order. These pages need not be either contiguous or in key order.

e.g. the linked page chain might be 1:2000 <-> 1:157 <-> 1:7053

When a page split happens a new page is allocated from anywhere in the filegroup (from either a mixed extent, for small tables or a non-empty uniform extent belonging to that object or a newly allocated uniform extent). This might not even be in the same file if the filegroup contains more than one.

The degree to which the logical order and contiguity differ from the idealized physical version is the degree of logical fragmentation.

In a newly created database with a single file, I ran the following.

CREATE TABLE T
  (
     X TINYINT NOT NULL,
     Y CHAR(3000) NULL
  );

CREATE CLUSTERED INDEX ix
  ON T(X);

GO

--Insert 100 rows with values 1 - 100 in random order
DECLARE @C1 AS CURSOR,
        @X  AS INT

SET @C1 = CURSOR FAST_FORWARD
FOR SELECT number
    FROM   master..spt_values
    WHERE  type = 'P'
           AND number BETWEEN 1 AND 100
    ORDER  BY CRYPT_GEN_RANDOM(4)

OPEN @C1;

FETCH NEXT FROM @C1 INTO @X;

WHILE @@FETCH_STATUS = 0
  BEGIN
      INSERT INTO T (X)
      VALUES        (@X);

      FETCH NEXT FROM @C1 INTO @X;
  END

Then checked the page layout with

SELECT page_id,
       X,
       geometry::Point(page_id, X, 0).STBuffer(1)
FROM   T
       CROSS APPLY sys.fn_PhysLocCracker( %% physloc %% )
ORDER  BY page_id

The results were all over the place. The first row in key order (with value 1 - highlighted with an arrow below) was on nearly the last physical page.

Fragmentation can be reduced or removed by rebuilding or reorganizing an index to increase the correlation between logical order and physical order.

After running

ALTER INDEX ix ON T REBUILD;

I got the following

If the table has no clustered index it is called a heap.

Non clustered indexes can be built on either a heap or a clustered index. They always contain a row locator back to the base table. In the case of a heap, this is a physical row identifier (rid) and consists of three components (File:Page: Slot). In the case of a Clustered index, the row locator is logical (the clustered index key).

For the latter case if the non clustered index already naturally includes the CI key column(s) either as NCI key columns or INCLUDE-d columns then nothing is added. Otherwise, the missing CI key column(s) silently gets added to the NCI.

SQL Server always ensures that the key columns are unique for both types of indexes. The mechanism in which this is enforced for indexes not declared as unique differs between the two index types, however.

Clustered indexes get a uniquifier added for any rows with key values that duplicate an existing row. This is just an ascending integer.

For non clustered indexes not declared as unique SQL Server silently adds the row locator into the non clustered index key. This applies to all rows, not just those that are actually duplicates.

The clustered vs non clustered nomenclature is also used for column store indexes. The paper Enhancements to SQL Server Column Stores states

Although column store data is not really "clustered" on any key, we decided to retain the traditional SQL Server convention of referring to the primary index as a clustered index.

Actually, You can achieve this with current typescript:

type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];

export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;

Examples:

// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];

// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
//   Types of property 'length' are incompatible.
//     Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];

// Error:
// Property '3' is missing in type '[string, string, string]' but required in type 
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];

EDIT (after a long time)

This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):

type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;

type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExpRev<[...A, ...P[0]], N, P>,
  1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];

type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExp<[...A, ...A], N, [A, ...P]>,
  1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];

export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;

Another solution which works better for me than pp or awesome_print:

require 'pry' # must install the gem... but you ALWAYS want pry installed anyways
Pry::ColorPrinter.pp(obj)

To escape %, you will need to double it up: %%.

Here is mine

import math

def is_prime(num):

    if num % 2 == 0 and num > 2: 
       return False
    for i in range(3, int(math.sqrt(num)) + 1, 2):
        if num % i == 0:
            return False
    return True

You need replace all occurrences of:

from django.core.urlresolvers import reverse

to:

from django.urls import reverse

NOTE: The same apply to reverse_lazy

in Pycharm Cmd+Shift+R for starting replacment in Path.

A PHP file must have permissions set to 644. Any folder containing PHP files and PHP access (to upload files, for example) must have permissions set to 755. PHP will run a 500 error when dealing with any file or folder that has permissions set to 777!

Often, this error means your program is too large, and often it's too large because it contains one or more very large data objects. For example,

char large_array[1ul << 31];
int other_global;
int main(void) { return other_global; }

will produce a "relocation truncated to fit" error on x86-64/Linux, if compiled in the default mode and without optimization. (If you turn on optimization, it could, at least theoretically, figure out that large_array is unused and/or that other_global is never written, and thus generate code that doesn't trigger the problem.)

What's going on is that, by default, GCC uses its "small code model" on this architecture, in which all of the program's code and statically allocated data must fit into the lowest 2GB of the address space. (The precise upper limit is something like 2GB - 2MB, because the very lowest 2MB of any program's address space is permanently unusable. If you are compiling a shared library or position-independent executable, all of the code and data must still fit into two gigabytes, but they're not nailed to the bottom of the address space anymore.) large_array consumes all of that space by itself, so other_global is assigned an address above the limit, and the code generated for main cannot reach it. You get a cryptic error from the linker, rather than a helpful "large_array is too large" error from the compiler, because in more complex cases the compiler can't know that other_global will be out of reach, so it doesn't even try for the simple cases.

Most of the time, the correct response to getting this error is to refactor your program so that it doesn't need gigantic static arrays and/or gigabytes of machine code. However, if you really have to have them for some reason, you can use the "medium" or "large" code models to lift the limits, at the price of somewhat less efficient code generation. These code models are x86-64-specific; something similar exists for most other architectures, but the exact set of "models" and the associated limits will vary. (On a 32-bit architecture, for instance, you might have a "small" model in which the total amount of code and data was limited to something like 2²⁴ bytes.)

 git mv common include

should work.

From the git mv man page:

git mv [-f] [-n] [-k] <source> ... <destination directory>

In the second form, the last argument has to be an existing directory; the given sources will be moved into this directory.
The index is updated after successful completion, but the change must still be committed.

No "git add" should be done before the move.

Note: "git mv A B/", when B does not exist as a directory, should error out, but it didn't.

See commit c57f628 by Matthieu Moy (moy) for Git 1.9/2.0 (Q1 2014):

Git used to trim the trailing slash, and make the command equivalent to 'git mv file no-such-dir', which created the file no-such-dir (while the trailing slash explicitly stated that it could only be a directory).

This patch skips the trailing slash removal for the destination path.
The path with its trailing slash is passed to rename(2), which errors out with the appropriate message:

$ git mv file no-such-dir/
fatal: renaming 'file' failed: Not a directory

Two changes are needed:

1. Change the return type of the method from Array[] to ArtWorkData[]
2. Change Labels[] in the return statement to Labels

I have done with this.

sudo apt-get update
sudo apt-get install build-essential chrpath git-core libssl-dev libfontconfig1-dev
git clone git://github.com/ariya/phantomjs.git
cd phantomjs

./build.sh

Yes, the biggest difference is that reject is a callback function that gets carried out after the promise is rejected, whereas throw cannot be used asynchronously. If you chose to use reject, your code will continue to run normally in asynchronous fashion whereas throw will prioritize completing the resolver function (this function will run immediately).

An example I've seen that helped clarify the issue for me was that you could set a Timeout function with reject, for example:

new Promise((resolve, reject) => {
  setTimeout(()=>{reject('err msg');console.log('finished')}, 1000);
  return resolve('ret val')
})
.then((o) => console.log("RESOLVED", o))
.catch((o) => console.log("REJECTED", o));

The above could would not be possible to write with throw.

try{
  new Promise((resolve, reject) => {
    setTimeout(()=>{throw new Error('err msg')}, 1000);
    return resolve('ret val')
  })
  .then((o) => console.log("RESOLVED", o))
  .catch((o) => console.log("REJECTED", o));
}catch(o){
  console.log("IGNORED", o)
}

In the OP's small example the difference in indistinguishable but when dealing with more complicated asynchronous concept the difference between the two can be drastic.

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

If you want your form's field clear, you must only add a delay in the onClick event like:

<input name="submit" id="MyButton" type="submit" class="btn-lg" value="ClickMe" onClick="setTimeout('clearform()', 2000 );"

onClick="setTimeout('clearform()', 1500 );" . in 1,5 seconds its clear

document.getElementById("name").value = "";  <<<<<<just correct this
document.getElementById("telephone").value = "";    <<<<<correct this

By clearform(), I mean your clearing-fields function.

Use an SqlDataAdapter when wanting to populate an in-memory DataSet/DataTable from the database. You then have the flexibility to close/dispose off the connection, pass the datatable/set around in memory. You could then manipulate the data and persist it back into the DB using the data adapter, in conjunction with InsertCommand/UpdateCommand.

Use an SqlDataReader when wanting fast, low-memory footprint data access without the need for flexibility for e.g. passing the data around your business logic. This is more optimal for quick, low-memory usage retrieval of large data volumes as it doesn't load all the data into memory all in one go - with the SqlDataAdapter approach, the DataSet/DataTable would be filled with all the data so if there's a lot of rows & columns, that will require a lot of memory to hold.

 int[][] myNums = { {1, 2, 3, 4, 5, 6, 7}, {5, 6, 7, 8, 9, 10, 11} };
 for (int x = 0; x < myNums.length; ++x) {
    for(int y = 0; y < myNums[i].length; ++y) {
       System.out.print(myNums[x][y]);
    }
 }

Output

1 2 3 4 5 6 7 5 6 7 8 9 10 11

Not best answer but you can reuse an already created ca bundle using --cert option of pip, for instance:

pip install SQLAlchemy==1.1.15 --cert="C:\Users\myUser\certificates\my_ca-bundle.crt"

The most succinct way to do this is:

Get-WmiObject -Class win32_computersystem -Property *

Here is the process that is more simple and works both for the formats dd/mm/yyyy and dd-mm-yyyy. This is working great for me:

    <?php

       $birthday = '26/04/1994';

       $dob = strtotime(str_replace("/", "-", $birthday));
       $tdate = time();
       echo date('Y', $tdate) - date('Y', $dob);

   ?>

And if you care about your time zone just add above date_default_timezone_set("Asia/Dhaka"); change the zone with yours.

From here you can use

#  For single line comments
-- Also for single line, must be followed by space/control character
/*
    C-style multiline comment
*/

From the composer help create-project command

The create-project command creates a new project from a given
package into a new directory. If executed without params and in a directory with a composer.json file it installs the packages for the current project.
You can use this command to bootstrap new projects or setup a clean
version-controlled installation for developers of your project.

[version]
You can also specify the version with the package name using = or : as separator.
To install unstable packages, either specify the version you want, or use the --stability=dev (where dev can be one of RC, beta, alpha or dev).

This command works:

composer create-project laravel/laravel=4.1.27 your-project-name --prefer-dist

This works with the * notation.

I agree that it is not possible in general.

The only thing CSS3 can do (which helped in my case) is to select elements that have no children:

table td:empty
{
   background-color: white;
}

Or have any children (including text):

table td:not(:empty)
{
   background-color: white;
}

Happened to me as well. In my case, the bad ref was master, and I did the following:

rm .git/refs/remotes/origin/master
git fetch

This made git restore the ref file. After that everything worked as expected again.

#!/usr/bin/python
# -*- coding: utf-8 -*-
# Works on python 3 and python 2.
# when server knows where the request is coming from.

import sys

if sys.version_info[0] == 3:
    from urllib.request import urlopen
else:
    from urllib import urlopen
with urlopen('https://www.facebook.com/') as \
    url:
    data = url.read()

print data

# When the server does not know where the request is coming from.
# Works on python 3.

import urllib.request

user_agent = \
    'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.0.7) Gecko/2009021910 Firefox/3.0.7'

url = 'https://www.facebook.com/'
headers = {'User-Agent': user_agent}

request = urllib.request.Request(url, None, headers)
response = urllib.request.urlopen(request)
data = response.read()
print data

If other solutions does not look good for some reason, you can still use this good old workaround of presenting with the delay of 0, like this:

dispatch_after(0, dispatch_get_main_queue(), ^{
    finishViewController *finished = [self.storyboard instantiateViewControllerWithIdentifier:@"finishViewController"];
    [self presentViewController:finished animated:NO completion:NULL];    
});

While I've seen no documented guarantee that your VC would be on the view hierarchy on the time dispatch block is scheduled to execution, I've observed it would work just fine.

Using delay of e.g. 0.2 sec is also an option. And the best thing - this way you don't need to mess with boolean variable in viewDidAppear:

If you're meaning to make a server call from the client, you should use Ajax - look at something like Jquery and use $.Ajax() or $.getJson() to call the server function, depending on what kind of return you're after or action you want to execute.

If you want to redirect, just use window.location. Like so:

window.location = "http://www.redirectedsite.com"

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

If you want to search on both FROM and TO airports, you'll want to join on the Airports table twice - then you can use both from and to tables in your results set:

SELECT
   Flights.*,fromAirports.*,toAirports.*
FROM
   Flights
INNER JOIN 
   Airports fromAirports on Flights.fairport = fromAirports.code
INNER JOIN 
   Airports toAirports on Flights.tairport = toAirports.code
WHERE
 ...

In the current version of Sublime Text 2 (Build: 2139), you can set the syntax for all files of a certain file extension using an option in the menu bar. Open a file with the extension you want to set a default for and navigate through the following menus: View -> Syntax -> Open all with current extension as... ->[your syntax choice].

Updated 2012-06-28: Recent builds of Sublime Text 2 (at least since Build 2181) have allowed the syntax to be set by clicking the current syntax type in the lower right corner of the window. This will open the syntax selection menu with the option to Open all with current extension as... at the top of the menu.

Updated 2016-04-19: As of now, this also works for Sublime Text 3.

That approach will be good if the date-time in question is in UTC, or represents local time in an area that has never observed daylight saving time. The DateTime difference routines do not take into account Daylight Saving Time, and consequently will regard midnight June 1 as being a multiple of 24 hours after midnight January 1. I'm unaware of anything in Windows that reports historical daylight-saving rules for the current locale, so I don't think there's any good way to correctly handle any time prior to the most recent daylight-saving rule change.

The error you quote has nothing to do with pg_hba.conf; it's failing to connect, not failing to authorize the connection.

Do what the error message says:

Check that the hostname and port are correct and that the postmaster is accepting TCP/IP connections

You haven't shown the command that produces the error. Assuming you're connecting on localhost port 5432 (the defaults for a standard PostgreSQL install), then either:

• PostgreSQL isn't running

• PostgreSQL isn't listening for TCP/IP connections (listen_addresses in postgresql.conf)

• PostgreSQL is only listening on IPv4 (0.0.0.0 or 127.0.0.1) and you're connecting on IPv6 (::1) or vice versa. This seems to be an issue on some older Mac OS X versions that have weird IPv6 socket behaviour, and on some older Windows versions.

• PostgreSQL is listening on a different port to the one you're connecting on

• (unlikely) there's an iptables rule blocking loopback connections

(If you are not connecting on localhost, it may also be a network firewall that's blocking TCP/IP connections, but I'm guessing you're using the defaults since you didn't say).

So ... check those:

• ps -f -u postgres should list postgres processes

• sudo lsof -n -u postgres |grep LISTEN or sudo netstat -ltnp | grep postgres should show the TCP/IP addresses and ports PostgreSQL is listening on

BTW, I think you must be on an old version. On my 9.3 install, the error is rather more detailed:

$ psql -h localhost -p 12345
psql: could not connect to server: Connection refused
        Is the server running on host "localhost" (::1) and accepting
        TCP/IP connections on port 12345?

An ASP.NET HTTP handler is the process (frequently referred to as the "endpoint") that runs in response to a request made to an ASP.NET Web application. The most common handler is an ASP.NET page handler that processes .aspx files. When users request an .aspx file, the request is processed by the page via the page handler.

The ASP.NET page handler is only one type of handler. ASP.NET comes with several other built-in handlers such as the Web service handler for .asmx files.

You can create custom HTTP handlers when you want special handling that you can identify using file name extensions in your application. For example, the following scenarios would be good uses of custom HTTP handlers:

RSS feeds To create an RSS feed for a site, you can create a handler that emits RSS-formatted XML. You can then bind the .rss extension (for example) in your application to the custom handler. When users send a request to your site that ends in .rss, ASP.NET will call your handler to process the request.

Image server If you want your Web application to serve images in a variety of sizes, you can write a custom handler to resize images and then send them back to the user as the handler's response.

HTTP handlers have access to the application context, including the requesting user's identity (if known), application state, and session information. When an HTTP handler is requested, ASP.NET calls the ProcessRequest method on the appropriate handler. The handler's ProcessRequest method creates a response, which is sent back to the requesting browser. As with any page request, the response goes through any HTTP modules that have subscribed to events that occur after the handler has run.

how to validate the select "qualifica" it has 3 choose

$(document).ready(function(){

It isn't possible as DateTime is immutable. The same discussion is available here: How to change time in datetime?

You can use the collate clause in a query (I can't find my example right now, so my syntax is probably wrong - I hope it points you in the right direction)

select sone_field collate SQL_Latin1_General_CP850_CI_AI
  from table_1
    inner join table_2
      on (table_1.field collate SQL_Latin1_General_CP850_CI_AI = table_2.field)
  where whatever

You can do a post/get using a library which allows you to use HttpClient with strongly-typed callbacks.

The data and the error are available directly via these callbacks.

The library is called angular-extended-http-client.

angular-extended-http-client library on GitHub

angular-extended-http-client library on NPM

Very easy to use.

Traditional approach

In the traditional approach you return Observable<HttpResponse<T>> from Service API. This is tied to HttpResponse.

With this approach you have to use .subscribe(x => ...) in the rest of your code.

This creates a tight coupling between the http layer and the rest of your code.

Strongly-typed callback approach

You only deal with your Models in these strongly-typed callbacks.

Hence, The rest of your code only knows about your Models.

Sample usage

The strongly-typed callbacks are

Success:

• IObservable<T>
• IObservableHttpResponse
• IObservableHttpCustomResponse<T>

Failure:

• IObservableError<TError>
• IObservableHttpError
• IObservableHttpCustomError<TError>

Add package to your project and in your app module

import { HttpClientExtModule } from 'angular-extended-http-client';

and in the @NgModule imports

  imports: [
    .
    .
    .
    HttpClientExtModule
  ],

Your Models

export class SearchModel {
    code: string;
}

//Normal response returned by the API.
export class RacingResponse {
    result: RacingItem[];
}

//Custom exception thrown by the API.
export class APIException {
    className: string;
}

Your Service

In your Service, you just create params with these callback types.

Then, pass them on to the HttpClientExt's get method.

import { Injectable, Inject } from '@angular/core'
import { SearchModel, RacingResponse, APIException } from '../models/models'
import { HttpClientExt, IObservable, IObservableError, ResponseType, ErrorType } from 'angular-extended-http-client';
.
.

@Injectable()
export class RacingService {

    //Inject HttpClientExt component.
    constructor(private client: HttpClientExt, @Inject(APP_CONFIG) private config: AppConfig) {

    }

    //Declare params of type IObservable<T> and IObservableError<TError>.
    //These are the success and failure callbacks.
    //The success callback will return the response objects returned by the underlying HttpClient call.
    //The failure callback will return the error objects returned by the underlying HttpClient call.
    searchRaceInfo(model: SearchModel, success: IObservable<RacingResponse>, failure?: IObservableError<APIException>) {
        let url = this.config.apiEndpoint;

        this.client.post<SearchModel, RacingResponse>(url, model, 
                                                      ResponseType.IObservable, success, 
                                                      ErrorType.IObservableError, failure);
    }
}

Your Component

In your Component, your Service is injected and the searchRaceInfo API called as shown below.

  search() {    


    this.service.searchRaceInfo(this.searchModel, response => this.result = response.result,
                                                  error => this.errorMsg = error.className);

  }

Both, response and error returned in the callbacks are strongly typed. Eg. response is type RacingResponse and error is APIException.

MySQL Workbench worked like a charm.

I just backed up database structure to SQL script and used it in "Create EER Model From SQL Script" of MWB 5.2.37 for Windows.

You can use an XMLHttpRequest to load a page into a div (or any other element of your page really). An exemple function would be:

function loadPage(){
if (window.XMLHttpRequest){
    // code for IE7+, Firefox, Chrome, Opera, Safari
    xmlhttp=new XMLHttpRequest();
}else{
    // code for IE6, IE5
    xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}

xmlhttp.onreadystatechange=function(){
    if (xmlhttp.readyState==4 && xmlhttp.status==200){
        document.getElementById("ID OF ELEMENT YOU WANT TO LOAD PAGE IN").innerHTML=xmlhttp.responseText;
    }
}

xmlhttp.open("POST","WEBPAGE YOU WANT TO LOAD",true);
xmlhttp.send();
}

If your sever is capable, you could also use PHP to do this, but since you're asking for an HTML5 method, this should be all you need.

I like the following:

public String readLine(String tPromptString) {
    byte[] tBuffer = new byte[256];
    int tPos = 0;
    System.out.print(tPromptString);

    while(true) {
        byte tNextByte = readByte();
        if(tNextByte == 10) {
            return new String(tBuffer, 0, tPos);
        }

        if(tNextByte != 13) {
            tBuffer[tPos] = tNextByte;
            ++tPos;
        }
    }
}

and for example, I would do:

String name = this.readLine("What is your name?")

Oracle is not sql server. Try the following in SQL Developer

variable rc refcursor;
exec testproc(:rc2);
print rc2

You can't do this without some browser specific code, since they implement text select ranged slightly differently. However, there are plugins that abstract this away. For exactly what you're after, there's the jQuery Caret (jCaret) plugin.

For your code to get the position you could do something like this:

$("#myTextInput").bind("keydown keypress mousemove", function() {
  alert("Current position: " + $(this).caret().start);
});

You can test it here.

Better answer will be

git config push.default current

upsteam works but when you have no branch on origin then you will need to set the upstream branch. Changing it to current will automatically set the upsteam branch and will push the branch immediately.

Quick-to-write alterantive

Even though is not the fastest choice, if performance is not an issue you can use:

sum(~np.isnan(data)).

Performance:

In [7]: %timeit data.size - np.count_nonzero(np.isnan(data))
10 loops, best of 3: 67.5 ms per loop

In [8]: %timeit sum(~np.isnan(data))
10 loops, best of 3: 154 ms per loop

In [9]: %timeit np.sum(~np.isnan(data))
10 loops, best of 3: 140 ms per loop

Simplest way would be to define default and allow it to be overridden. I am not sure what is the use of systemProperty in this case. Simple arguments will do the job.

def profiles = 'prod'

bootRun {
  args = ["--spring.profiles.active=" + profiles]
}

To run dev:

./gradlew bootRun -Pdev

To add dependencies on your task you can do something like this:

task setDevProperties(dependsOn: bootRun) << {
  doFirst {
    System.setProperty('spring.profiles.active', profiles)
  }
}

There are lots of ways achieving this in Gradle.

Edit:

Configure separate configuration files per environment.

if (project.hasProperty('prod')) {
  apply from: 'gradle/profile_prod.gradle'
} else {
  apply from: 'gradle/profile_dev.gradle'
}

Each configuration can override tasks for example:

def profiles = 'prod'
bootRun {
  systemProperty "spring.profiles.active", activeProfile
}

Run by providing prod flag in this case just like that:

./gradlew <task> -Pprod

You may check if you have the directory where are the packages of Python (in my machine, this dir is C:\Python27\lib\site-packages) in the Path variable on Windows. If Python's path environment variable does not have this directory, you will not find the packages.

You should be able to accomplish this by using the statement $ErrorActionPreference = "Stop" at the beginning of your scripts.

The default setting of $ErrorActionPreference is Continue, which is why you are seeing your scripts keep going after errors occur.

Use sort -n or sort --numeric-sort.

You have the syntax wrong; there is no need to place a period inside a double-quoted string. Instead, it should be more like

$query = mysql_query("SELECT * FROM table WHERE the_number LIKE '$prefix%'");

You can confirm this by printing out the string to see that it turns out identical to the first case.

Of course it's not a good idea to simply inject variables into the query string like this because of the danger of SQL injection. At the very least you should manually escape the contents of the variable with mysql_real_escape_string, which would make it look perhaps like this:

$sql = sprintf("SELECT * FROM table WHERE the_number LIKE '%s%%'",
               mysql_real_escape_string($prefix));
$query = mysql_query($sql);

Note that inside the first argument of sprintf the percent sign needs to be doubled to end up appearing once in the result.

Three problems here:

1. Just use String.matches() - if the API is there, use it
2. In java "matches" means "matches the entire input", which IMHO is counter-intuitive, so let your method's API reflect that by letting callers think about matching part of the input as your example suggests
3. You regex matches only 1 character

I recommend you use code like this:

public boolean matches(String regex) {
    regex = "^.*" + regex + ".*$"; // pad with regex to allow partial matching
    System.out.println("abcABC   ".matches(regex));
    return "abcABC   ".matches(regex);
}

public static void main(String[] args) {
    HowEasy words = new HowEasy();
    words.matches("[a-zA-Z]+"); // added "+" (ie 1-to-n of) to character class
}

For those who are looking for making TextField or TextFormField accept only numbers as input, try this code block :

for flutter 1.20 or newer versions

TextFormField(
              controller: _controller,
              keyboardType: TextInputType.number,
              inputFormatters: <TextInputFormatter>[
                FilteringTextInputFormatter.allow(RegExp(r'[0-9]')),
              ],
              decoration: InputDecoration(
                  labelText: "whatever you want",
                  hintText: "whatever you want",
                  icon: Icon(Icons.phone_iphone)))

for earlier versions of 1.20

TextFormField(
    controller: _controller,
    keyboardType: TextInputType.number,
    inputFormatters: <TextInputFormatter>[
        WhitelistingTextInputFormatter.digitsOnly
    ],
    decoration: InputDecoration(
        labelText:"whatever you want", 
        hintText: "whatever you want",
        icon: Icon(Icons.phone_iphone)
    )
)

You can use org.modeshape.common.text.Inflector.

Specifically:

String camelCase(String lowerCaseAndUnderscoredWord,
    boolean uppercaseFirstLetter, char... delimiterChars) 

By default, this method converts strings to UpperCamelCase.

Very Short and concise Answer

lateinit: It initialize non-null properties lately

Unlike lazy initialization, lateinit allows the compiler to recognize that the value of the non-null property is not stored in the constructor stage to compile normally.

lazy Initialization

by lazy may be very useful when implementing read-only(val) properties that perform lazy-initialization in Kotlin.

by lazy { ... } performs its initializer where the defined property is first used, not its declaration.

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

This is the most elegant solution I've been using for a while. It doesn't require external counter variable and it provides nice degree of encapsulation.

var urls = ['http://..', 'http://..', ..];

function ajaxRequest (urls) {
    if (urls.length > 0) {
        $.ajax({
            method: 'GET',
            url: urls.pop()
        })
        .done(function (result)) {
            ajaxRequest(urls);
        });
    }
}

ajaxRequest(urls); 

I think you are referring to the problem in C (and C++) that returning an array from a function isn't allowed (or at least won't work as expected) - this is because the array return will (if you write it in the simple form) return a pointer to the actual array on the stack, which is then promptly removed when the function returns.

But in this case, it works, because the std::vector is a class, and classes, like structs, can (and will) be copied to the callers context. [Actually, most compilers will optimise out this particular type of copy using something called "Return Value Optimisation", specifically introduced to avoid copying large objects when they are returned from a function, but that's an optimisation, and from a programmers perspective, it will behave as if the assignment constructor was called for the object]

As long as you don't return a pointer or a reference to something that is within the function returning, you are fine.

Here is the tried and tested solution for this query in any situation - like if 1st of the month is on Friday , then also this will work -

select (DATEPART(wk,@date_given)-DATEPART(wk,dateadd(d,1-day(@date_given),@date_given)))+1

above are some solutions which will fail if the month's first date is on Friday , then 4th will be 2nd week of the month

You can use the Bean Comparator to sort on any property in your custom class.

I had the same issue and found the answer here.

The problem is that the bat uses de reg command and it searches that in the PATH system variable. Somehow you have managed to get "C:\Windows\System32" out of the PATH variable, so just go to the system variables (right click "My Computer" > "Properties" > advanced config > "Environment Variables", search the PATH variable and add at the end separated by ";" : C:\Windows\System32

I've written a simple class for rotating image. All you've to do is input image and angle of rotation in Degree. Angle must be between -90 and +90.

public class ImageRotator
{
    private readonly Bitmap image;
    public Image OriginalImage
    {
        get { return image; }
    }


    private ImageRotator(Bitmap image)
    {
        this.image = image;
    }


    private double GetRadian(double degree)
    {
        return degree * Math.PI / (double)180;
    }


    private Size CalculateSize(double angle)
    {
        double radAngle = GetRadian(angle);
        int width = (int)(image.Width * Math.Cos(radAngle) + image.Height * Math.Sin(radAngle));
        int height = (int)(image.Height * Math.Cos(radAngle) + image.Width * Math.Sin(radAngle));
        return new Size(width, height);
    }

    private PointF GetTopCoordinate(double radAngle)
    {
        Bitmap image = CurrentlyViewedMappedImage.BitmapImage;
        double topX = 0;
        double topY = 0;

        if (radAngle > 0)
        {
            topX = image.Height * Math.Sin(radAngle);
        }
        if (radAngle < 0)
        {
            topY = image.Width * Math.Sin(-radAngle);
        }
        return new PointF((float)topX, (float)topY);
    }

    public Bitmap RotateImage(double angle)
    {
        SizeF size = CalculateSize(radAngle);
        Bitmap rotatedBmp = new Bitmap((int)size.Width, (int)size.Height);

        Graphics g = Graphics.FromImage(rotatedBmp);
        g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
        g.CompositingQuality = CompositingQuality.HighQuality;
        g.SmoothingMode = SmoothingMode.HighQuality;
        g.PixelOffsetMode = PixelOffsetMode.HighQuality;

        g.TranslateTransform(topPoint.X, topPoint.Y);
        g.RotateTransform(GetDegree(radAngle));
        g.DrawImage(image, new RectangleF(0, 0, size.Width, size.Height));

        g.Dispose();
        return rotatedBmp;
    }


    public static class Builder
    {
        public static ImageRotator CreateInstance(Image image)
        {
            ImageRotator rotator = new ImageRotator(image as Bitmap);
            return rotator;
        }
    }
}

You have to change delimiter before using triggers, stored procedures and so on.

delimiter //
create procedure ProG() 
begin 
SELECT * FROM hs_hr_employee_leave_quota;
end;//
delimiter ;

You can use a JsonPath query to extract the value. And with JsonSurfer which is backed by Gson, your problem can be solved by simply two line of code!

    JsonSurfer jsonSurfer = JsonSurfer.gson();
    String result = jsonSurfer.collectOne(jsonLine, String.class, "$.data.translations[0].translatedText");

It should also be noted that one key detail about package-lock.json is that it cannot be published, and it will be ignored if found in any place other than the top level package. It shares a format with npm-shrinkwrap.json(5), which is essentially the same file, but allows publication. This is not recommended unless deploying a CLI tool or otherwise using the publication process for producing production packages.

If both package-lock.json and npm-shrinkwrap.json are present in the root of a package, package-lock.json will be completely ignored.

I had a similar experience, so here are the things that I tried

Firstly, I tried to install mysql's required packages by running the command below in my terminal

sudo apt-get install build-essential libmysqlclient-dev

Secondly, I tried updating rubygems on my system by running the command below in my terminal

sudo gem update --system

But I was still experiencing the same issue. After much research I realized that I was using an almost out-of-date version of the mysql gem. I simply needed to use the mysql2 gem (mysql2 gem)and not the mysql gem, so I fixed it by running the command below in my terminal

gem install mysql2

This worked fine for me. Before running the last command, ensure that you've ran the first and second commands to be sure that everything is fine on your system.

That's all.

I hope this helps

It works for me with

logging.level.org.hibernate.SQL= DEBUG

logging.level.org.hibernate.type=TRACE

There is no "callback" in C - not more than any other generic programming concept.

They're implemented using function pointers. Here's an example:

void populate_array(int *array, size_t arraySize, int (*getNextValue)(void))
{
    for (size_t i=0; i<arraySize; i++)
        array[i] = getNextValue();
}

int getNextRandomValue(void)
{
    return rand();
}

int main(void)
{
    int myarray[10];
    populate_array(myarray, 10, getNextRandomValue);
    ...
}

Here, the populate_array function takes a function pointer as its third parameter, and calls it to get the values to populate the array with. We've written the callback getNextRandomValue, which returns a random-ish value, and passed a pointer to it to populate_array. populate_array will call our callback function 10 times and assign the returned values to the elements in the given array.

Hope below Oracle query can help:

WITH Temp_table AS

    Select id, name, othercolumns, ROW_NUMBER() over (PARTITION BY name ORDER BY ID 
    desc)as rank from messages
)
Select id, name,othercolumns from Temp_table where rank=1

This is my unzip method, which I use:

private boolean unpackZip(String path, String zipname)
{       
     InputStream is;
     ZipInputStream zis;
     try 
     {
         is = new FileInputStream(path + zipname);
         zis = new ZipInputStream(new BufferedInputStream(is));          
         ZipEntry ze;

         while((ze = zis.getNextEntry()) != null) 
         {
             ByteArrayOutputStream baos = new ByteArrayOutputStream();
             byte[] buffer = new byte[1024];
             int count;

             String filename = ze.getName();
             FileOutputStream fout = new FileOutputStream(path + filename);

             // reading and writing
             while((count = zis.read(buffer)) != -1) 
             {
                 baos.write(buffer, 0, count);
                 byte[] bytes = baos.toByteArray();
                 fout.write(bytes);             
                 baos.reset();
             }

             fout.close();               
             zis.closeEntry();
         }

         zis.close();
     } 
     catch(IOException e)
     {
         e.printStackTrace();
         return false;
     }

    return true;
}

Use the DATE function:

SELECT DATE(orders.date_purchased) AS date

As others have said, @Transient is used to mark fields which shouldn't be persisted. Consider this short example:

public enum Gender { MALE, FEMALE, UNKNOWN }

@Entity
public Person {
    private Gender g;
    private long id;

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    public long getId() { return id; }
    public void setId(long id) { this.id = id; }

    public Gender getGender() { return g; }    
    public void setGender(Gender g) { this.g = g; }

    @Transient
    public boolean isMale() {
        return Gender.MALE.equals(g);
    }

    @Transient
    public boolean isFemale() {
        return Gender.FEMALE.equals(g);
    }
}

When this class is fed to the JPA, it persists the gender and id but doesn't try to persist the helper boolean methods - without @Transient the underlying system would complain that the Entity class Person is missing setMale() and setFemale() methods and thus wouldn't persist Person at all.

for x in y[:-1]

If y is a generator, then the above will not work.

You could do something like this for your case - (syntax may be a bit off). Also look at this link

subQuery = (from crtu in CompanyRolesToUsers where crtu.RoleId==2 || crtu.RoleId==3 select crtu.UserId).ToArrayList();

finalQuery = from u in Users where u.LastName.Contains('fra')  && subQuery.Contains(u.Id) select u;

You can sort the dataFrame by count and then remove duplicates. I think it's easier:

df.sort_values('count', ascending=False).drop_duplicates(['Sp','Mt'])

Using org.apache.commons.lang3.time.DateUtils

Date pDate = new Date();
DateUtils.truncate(pDate, Calendar.DAY_OF_MONTH);

Open Terminal:

sudo gem update --system 

It works!

Like this?

$string = 'FirstPart SecondPart'
$a,$b = $string.split(' ')
$a
$b

In addition to previous answers there is one important for me note:

shelve is JetBrains products feature (such as WebStorm, PhpStorm, PyCharm, etc.). It puts shelved files into .idea/shelf directory.

stash is one of git options. It puts stashed files under the .git directory.

Take a look at Rick Hightower's approach. His approach avoids configuring ObjectMapper as a singleton and allows you to filter the JSON response for the same object in different ways per each request method.

http://www.jroller.com/RickHigh/entry/filtering_json_feeds_from_spring

The Date object handles 8601 as it's first parameter:

var d = new Date("2014-04-07T13:58:10.104Z");_x000D_
console.log(d.toString());

Use whoami /priv command to list all the user privileges.

Probably your problem is that for Docker that has been installed from default Ubuntu repository, the package name is docker.io

Or package name may be something like docker-ce. Try running

dpkg -l | grep -i docker

to identify what installed package you have

So you need to change package name in commands from https://stackoverflow.com/a/31313851/2340159 to match package name. For example, for docker.io it would be:

sudo apt-get purge -y docker.io
sudo apt-get autoremove -y --purge docker.io
sudo apt-get autoclean

It adds:

The above commands will not remove images, containers, volumes, or user created configuration files on your host. If you wish to delete all images, containers, and volumes run the following command:

sudo rm -rf /var/lib/docker

Remove docker from apparmor.d:

sudo rm /etc/apparmor.d/docker

Remove docker group:

sudo groupdel docker

Alternatively, you can start output buffering, do an include/require, and then stop buffering. With ob_get_contents(), you can just get the stuff that was outputted by that other PHP file into a variable.

logical data model

A logical data model describes the data in as much detail as possible, without regard to how they will be physical implemented in the database. Features of a logical data model include: · Includes all entities and relationships among them. · All attributes for each entity are specified. · The primary key for each entity is specified. · Foreign keys (keys identifying the relationship between different entities) are specified. · Normalization occurs at this level. conceptual data model

A conceptual data model identifies the highest-level relationships between the different entities. Features of conceptual data model include: · Includes the important entities and the relationships among them. · No attribute is specified. · No primary key is specified.

NSMutableArray *persons = [NSMutableArray array];
for (int i = 0; i < myPersonsCount; i++) {
   [persons addObject:[[Person alloc] init]];
}
NSArray *arrayOfPersons = [NSArray arrayWithArray:persons]; // if you want immutable array

also you can reach this without using NSMutableArray:

NSArray *persons = [NSArray array];
for (int i = 0; i < myPersonsCount; i++) {
   persons = [persons arrayByAddingObject:[[Person alloc] init]];
}

One more thing - it's valid for ARC enabled environment, if you going to use it without ARC don't forget to add autoreleased objects into array!

[persons addObject:[[[Person alloc] init] autorelease];

if (date1.getTime() > date2.getTime()) {
    alert("The first date is after the second date!");
}

Reference to Date object

This post is now nearly 5 years old! Python-2.7 will stop receiving official updates from python.org in 2020. Also, Python-3.7 has been released. Check out Python-Future on how to make your Python-2 code compatible with Python-3. For updating conda, the documentation now recommends using conda update --all in each of your conda environments to update all packages and the Python executable for that version. Also, since they changed their name to Anaconda, I don't know if the Windows registry keys are still the same.

There have been no updates to Python(x,y) since June of 2015, so I think it's safe to assume it has been abandoned.

As @cxw comments below, these answers are for the same bit-versions, and by bit-version I mean 64-bit vs. 32-bit. For example, these answers would apply to updating from 64-bit Python-2.7.10 to 64-bit Python-2.7.11, ie: the same bit-version. While it is possible to install two different bit versions of Python together, it would require some hacking, so I'll save that exercise for the reader. If you don't want to hack, I suggest that if switching bit-versions, remove the other bit-version first.

• Anaconda and MiniConda can be used with an existing Python installation by disabling the options to alter the Windows PATH and Registry. After extraction, create a symlink to conda in your bin or install conda from PyPI. Then create another symlink called conda-activate to activate in the Anaconda/Miniconda root bin folder. Now Anaconda/Miniconda is just like Ruby RVM. Just use conda-activate root to enable Anaconda/Miniconda.
• Portable Python is no longer being developed or maintained.

TL;DR

• Using Anaconda or miniconda, then just execute conda update --all to keep each conda environment updated,
• same major version of official Python (e.g. 2.7.5), just install over old (e.g. 2.7.4),
• different major version of official Python (e.g. 3.3), install side-by-side with old, set paths/associations to point to dominant (e.g. 2.7), shortcut to other (e.g. in BASH $ ln /c/Python33/python.exe python3).

The answer depends:

1. If OP has 2.7.x and wants to install newer version of 2.7.x, then

   • if using MSI installer from the official Python website, just install over old version, installer will issue warning that it will remove and replace the older version; looking in "installed programs" in "control panel" before and after confirms that the old version has been replaced by the new version; newer versions of 2.7.x are backwards compatible so this is completely safe and therefore IMHO multiple versions of 2.7.x should never necessary.
   • if building from source, then you should probably build in a fresh, clean directory, and then point your path to the new build once it passes all tests and you are confident that it has been built successfully, but you may wish to keep the old build around because building from source may occasionally have issues. See my guide for building Python x64 on Windows 7 with SDK 7.0.
   • if installing from a distribution such as Python(x,y), see their website. Python(x,y) has been abandoned. I believe that updates can be handled from within Python(x,y) with their package manager, but updates are also included on their website. I could not find a specific reference so perhaps someone else can speak to this. Similar to ActiveState and probably Enthought, Python (x,y) clearly states it is incompatible with other installations of Python:

     It is recommended to uninstall any other Python distribution before installing Python(x,y)

   • Enthought Canopy uses an MSI and will install either into Program Files\Enthought or home\AppData\Local\Enthought\Canopy\App for all users or per user respectively. Newer installations are updated by using the built in update tool. See their documentation.
   • ActiveState also uses an MSI so newer installations can be installed on top of older ones. See their installation notes.

     Other Python 2.7 Installations On Windows, ActivePython 2.7 cannot coexist with other Python 2.7 installations (for example, a Python 2.7 build from python.org). Uninstall any other Python 2.7 installations before installing ActivePython 2.7.

   • Sage recommends that you install it into a virtual machine, and provides a Oracle VirtualBox image file that can be used for this purpose. Upgrades are handled internally by issuing the sage -upgrade command.

   • Anaconda can be updated by using the conda command:

     conda update --all
     

     Anaconda/Miniconda lets users create environments to manage multiple Python versions including Python-2.6, 2.7, 3.3, 3.4 and 3.5. The root Anaconda/Miniconda installations are currently based on either Python-2.7 or Python-3.5.

     Anaconda will likely disrupt any other Python installations. Installation uses MSI installer. [UPDATE: 2016-05-16] Anaconda and Miniconda now use .exe installers and provide options to disable Windows PATH and Registry alterations.

     Therefore Anaconda/Miniconda can be installed without disrupting existing Python installations depending on how it was installed and the options that were selected during installation. If the .exe installer is used and the options to alter Windows PATH and Registry are not disabled, then any previous Python installations will be disabled, but simply uninstalling the Anaconda/Miniconda installation should restore the original Python installation, except maybe the Windows Registry Python\PythonCore keys.

     Anaconda/Miniconda makes the following registry edits regardless of the installation options: HKCU\Software\Python\ContinuumAnalytics\ with the following keys: Help, InstallPath, Modules and PythonPath - official Python registers these keys too, but under Python\PythonCore. Also uninstallation info is registered for Anaconda\Miniconda. Unless you select the "Register with Windows" option during installation, it doesn't create PythonCore, so integrations like Python Tools for Visual Studio do not automatically see Anaconda/Miniconda. If the option to register Anaconda/Miniconda is enabled, then I think your existing Python Windows Registry keys will be altered and uninstallation will probably not restore them.

   • WinPython updates, I think, can be handled through the WinPython Control Panel.
   • PortablePython is no longer being developed. It had no update method. Possibly updates could be unzipped into a fresh directory and then App\lib\site-packages and App\Scripts could be copied to the new installation, but if this didn't work then reinstalling all packages might have been necessary. Use pip list to see what packages were installed and their versions. Some were installed by PortablePython. Use easy_install pip to install pip if it wasn't installed.

2. If OP has 2.7.x and wants to install a different version, e.g. <=2.6.x or >=3.x.x, then installing different versions side-by-side is fine. You must choose which version of Python (if any) to associate with *.py files and which you want on your path, although you should be able to set up shells with different paths if you use BASH. AFAIK 2.7.x is backwards compatible with 2.6.x, so IMHO side-by-side installs is not necessary, however Python-3.x.x is not backwards compatible, so my recommendation would be to put Python-2.7 on your path and have Python-3 be an optional version by creating a shortcut to its executable called python3 (this is a common setup on Linux). The official Python default install path on Windows is

   • C:\Python33 for 3.3.x (latest 2013-07-29)
   • C:\Python32 for 3.2.x
   • &c.
   • C:\Python27 for 2.7.x (latest 2013-07-29)
   • C:\Python26 for 2.6.x
   • &c.

3. If OP is not updating Python, but merely updating packages, they may wish to look into virtualenv to keep the different versions of packages specific to their development projects separate. Pip is also a great tool to update packages. If packages use binary installers I usually uninstall the old package before installing the new one.

I hope this clears up any confusion.

I think placing text inbetween the tags is reserved for browsers that cant handle iframes i.e...

<iframe src ="html_intro.asp" width="100%" height="300">
  <p>Your browser does not support iframes.</p>
</iframe>

You use the 'src' attribute to set the source of the iframes html...

Hope that helps :)

In the load events, use Me.Hide .

In WebBrowser1.DocuementCompleted, use Me.Show

I found this by adapting some tutos. Thanks to google, and to all of you ;)

def findall(L, test):
    i=0
    indices = []
    while(True):
        try:
            # next value in list passing the test
            nextvalue = filter(test, L[i:])[0]

            # add index of this value in the index list,
            # by searching the value in L[i:] 
            indices.append(L.index(nextvalue, i))

            # iterate i, that is the next index from where to search
            i=indices[-1]+1
        #when there is no further "good value", filter returns [],
        # hence there is an out of range exeption
        except IndexError:
            return indices

A very simple use:

a = [0,0,2,1]
ind = findall(a, lambda x:x>0))

[2, 3]

P.S. scuse my english

If you want to know for sure whether a date gets parsed into something you expect, you can use DateTime::createFromFormat():

$d = DateTime::createFromFormat('d-m-Y', '22-09-2008');
if ($d === false) {
    die("Woah, that date doesn't look right!");
}
echo $d->format('Y-m-d'), PHP_EOL;
// prints 2008-09-22

It's obvious in this case, but e.g. 03-04-2008 could be 3rd of April or 4th of March depending on where you come from :)

You can use generators too, if generator expressions become too involved or complex:

def gen():
    for x in xyz:
        if x in a:
            yield x

for x in gen():
    print x

I accidentally encoded a file in UTF-7 and had a similar issue. When I typed file -i name.file I would get charset=us-ascii.

iconv -f us-ascii -t utf-9//translit name.file would not work since I've gathered UTF-7 is a subset of US ASCII, as is UTF-8.

To solve this, I entered

iconv -f UTF-7 -t UTF-8//TRANSLIT name.file -o output.file

I'm not sure how to determine the encoding other than what others have suggested here.

I have been looking for the best way to do that since not every method we want to call is located in Fragment with same Activity Parent.

In your Fragment

public void methodExemple(View view){

        // your code here

        Toast.makeText(view.getContext(), "Clicked clicked",Toast.LENGTH_LONG).show();
    }

In your Activity

new ExempleFragment().methodExemple(context); 

I was finding same but lastly i found an answer. I hope this answer help you so much.

when your array is empty then you can send empty array just like

if(!empty($result))
        {
            echo json_encode($result);
        }
        else
        {
            echo json_encode(array('data'=>''));
        }

Thank you

You can do like this :

input {
    vertical-align:middle;
}

label{
    color:#222;
    font-family:corbel,sans-serif;
    font-size: 14px;
}

If you use as following, your code can be more effective than you wrote. You should add another feature.

.abc, .xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a.abc, a.xyz {
margin-left:20px;
width: 100px;
height: 100px;
} 

OR

a {
margin-left:20px;
width: 100px;
height: 100px;
} 

The problem is that buttonClickedEvent is a member function and you need a pointer to member in order to invoke it.

Try this:

void (MyClass::*func)(int);
func = &MyClass::buttonClickedEvent;

And then when you invoke it, you need an object of type MyClass to do so, for example this:

(this->*func)(<argument>);

http://www.codeguru.com/cpp/cpp/article.php/c17401/C-Tutorial-PointertoMember-Function.htm

I suggest you to see "How do I run a bat file in the background from another bat file?"

Also, good answer (of using start command) was given in "Parallel execution of shell processes" question page here;

But my recommendation is to use PowerShell. I believe it will perfectly suit your needs.

You can't call methods outside a method. Code like this cannot float around in the class.

You need something like:

public class MyClass {

  UserInput input = new UserInput();

  public void foo() {
      input.name();
  }
}

or inside a constructor:

public class MyClass {

  UserInput input = new UserInput();

  public MyClass() {
      input.name();
  }
}

How about sapply (not really necessary for this simple case):

newData<- sapply(data, function(x) x^2)

If anyone here after updating to 5.1 this is how it works

StandardServiceRegistry registry = new StandardServiceRegistryBuilder().configure().build();
                MetadataSources sources = new MetadataSources(registry);
                Metadata metadata = sources.getMetadataBuilder().build();
                sessionFactory = metadata.getSessionFactoryBuilder().build();

instead of the below in hibernate 4.3

 ServiceRegistry serviceRegistry = new ServiceRegistryBuilder().applySettings(
            configuration.getProperties()). buildServiceRegistry();
    sessionFactory = configuration.buildSessionFactory(serviceRegistry);

Some permissions issue for default sample.

I wanted to see how it works, I am creating the first extension, so I downloaded a simpler one.

Downloaded 'Typed URL History' sample from

If you add this to your web.config transformation file, you can also set certain publish options to have debugging enabled or disabled:

<system.web>
    <customErrors mode="Off" defaultRedirect="~/Error.aspx" xdt:Transform="Replace"/>
</system.web>

override func setSelected(selected: Bool, animated: Bool) {
    // Configure the view for the selected state

    super.setSelected(selected, animated: animated)
    let selView = UIView()

    selView.backgroundColor = UIColor( red: 5/255, green: 159/255, blue:223/255, alpha: 1.0 )
    self.selectedBackgroundView = selView
}

Here is how you can solve this using a single WHERE clause:

WHERE (@myParm = value1 AND MyColumn IS NULL)
OR  (@myParm = value2 AND MyColumn IS NOT NULL)
OR  (@myParm = value3)

A naïve usage of the CASE statement does not work, by this I mean the following:

SELECT Field1, Field2 FROM MyTable
WHERE CASE @myParam
    WHEN value1 THEN MyColumn IS NULL
    WHEN value2 THEN MyColumn IS NOT NULL
    WHEN value3 THEN TRUE
END

It is possible to solve this using a case statement, see onedaywhen's answer

It has method to find all values from map:

Map<K, V> map=getMapObjectFromXyz();
Collection<V> vs= map.values();
     

Iterate over vs to do some operation

git push -f <remote-name> <branch-name>

I needed a 64-bit version of oracle.dataaccess.dll but this caused problems with other libraries I was using.

[BadImageFormatException: Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.]

I followed several steps above. Going to advance settings on the projects pool to toggle allow 32bit worked but I wasn't content to leave it like that so i turned it back on.

My project also had references that relied on Elmah and log4net references. I downloaded the latest version of these and my project was able to build and run fine without messing with the pools's allow 32bit setting.

The base dn is dc=example,dc=com.

I don't know about openca, but I will try this answer since you got very little traffic so far.

A base dn is the point from where a server will search for users. So I would try to simply use admin as a login name.

If openca behaves like most ldap aware applications, this is what is going to happen :

1. An ldap search for the user admin will be done by the server starting at the base dn (dc=example,dc=com).
2. When the user is found, the full dn (cn=admin,dc=example,dc=com) will be used to bind with the supplied password.
3. The ldap server will hash the password and compare with the stored hash value. If it matches, you're in.

Getting step 1 right is the hardest part, but mostly because we don't get to do it often. Things you have to look out for in your configuraiton file are :

• The dn your application will use to bind to the ldap server. This happens at application startup, before any user comes to authenticate. You will have to supply a full dn, maybe something like cn=admin,dc=example,dc=com.
• The authentication method. It is usually a "simple bind".
• The user search filter. Look at the attribute named objectClass for your admin user. It will be either inetOrgPerson or user. There will be others like top, you can ignore them. In your openca configuration, there should be a string like (objectClass=inetOrgPerson). Whatever it is, make sure it matches your admin user's object Class. You can specify two object class with this search filter (|(objectClass=inetOrgPerson)(objectClass=user)).

Download an LDAP Browser, such as Apache's Directory Studio. Connect using your application's credentials, so you will see what your application sees.

Having tried the css route for a while, I ended up writing something fairly basic in jQuery that did the job for me:

function iframeHeight() {
    var newHeight = $j(window).height();
    var buffer = 180;     // space required for any other elements on the page 
    var newIframeHeight = newHeight - buffer;
    $j('iframe').css('height',newIframeHeight);    //this will aply to all iframes on the page, so you may want to make your jquery selector more specific.
}

// When DOM ready
$(function() {
    window.onresize = iframeHeight;
}

Tested in IE8, Chrome, Firefox 3.6

EventHandler handler = (s, e) => MessageBox.Show("Woho");

button.Click += handler;
button.Click -= handler;

Or you could git checkout -b <new-branch> and git cherry-pick <commit> the before to the and git rebase to drop revert commit. send pull request like before.

The last question has an easy answer:

> .Machine$sizeof.pointer
[1] 8

Meaning I am running R64. If I were running 32 bit R it would return 4. Just because you are running a 64 bit OS does not mean you will be running 64 bit R, and from the error message it appears you are not.

EDIT: If the package has binaries, then they are in separate directories. The specifics will depend on the OS. Notice that your LoadLibrary error occurred when it attempted to find the dll in ...rJava/libs/x64/... On my MacOS system the ...rJava/libs/...` folder has 3 subdirectories: i386, ppc, and x86_64. (The ppc files are obviously useless baggage.)

All these suggestions are great, but kind of painful to follow because executing the code to construct the URL or constructing that crazy URL by hand is kind of annoying...

So, I threw together a quick web app to make things easier. Just paste the URL of the extension you want and out comes out the download of your extension already properly named: publisher-extension-version.vsix.

From Symfony2 documentation: Absolute URLs for assets were introduced in Symfony 2.5.

If you need absolute URLs for assets, you can set the third argument (or the absolute argument) to true:

Example:

<img src="{{ asset('images/logo.png', absolute=true) }}" alt="Symfony!" />

You could use a colormap such as HSV to generate a set of colors. For example:

cc=hsv(12);
figure; 
hold on;
for i=1:12
    plot([0 1],[0 i],'color',cc(i,:));
end

MATLAB has 13 different named colormaps ('doc colormap' lists them all).

Another option for plotting lines in different colors is to use the LineStyleOrder property; see Defining the Color of Lines for Plotting in the MATLAB documentation for more information.

you could make them all #'s.

You would then need to add return false; to the end of any function that is called onclick of the anchor to not have the page jump up to the top.

Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):

use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go

For anyone else who runs into this...

Version 1.2.0 of this plugin (current as of this post) doesn't quite work in all cases as documented with Bootstrap 3.0, but it does with a minor workaround.

Specifically, if using an input with icon, the HTML markup is of course slightly different as class names have changed:

<div class="input-group" data-datepicker="true">
    <input name="date" type="text" class="form-control" />
    <span class="input-group-addon"><i class="icon-calendar"></i></span>
</div>

It seems because of this, you need to use a selector that points directly to the input element itself NOT the parent container (which is what the auto generated HTML on the demo page suggests).

$('*[data-datepicker="true"] input[type="text"]').datepicker({
    todayBtn: true,
    orientation: "top left",
    autoclose: true,
    todayHighlight: true
});

Having done this you will probably also want to add a listener for clicking/tapping on the icon so it sets focus on the text input when clicked (which is the behaviour when using this plugin with TB 2.x by default).

$(document).on('touch click', '*[data-datepicker="true"] .input-group-addon', function(e){
    $('input[type="text"]', $(this).parent()).focus();
});

NB: I just use a data-datepicker boolean attribute because the class name 'datepicker' is reserved by the plugin and I already use 'date' for styling elements.

From here:

One way to conserve system resources is to configure idle time-out settings for the worker processes in an application pool. When these settings are configured, a worker process will shut down after a specified period of inactivity. The default value for idle time-out is 20 minutes.

Also check Why is the IIS default app pool recycle set to 1740 minutes?

If you have a just a few sites on your server and you want them to always load fast then set this to zero. Otherwise, when you have 20 minutes without any traffic then the app pool will terminate so that it can start up again on the next visit. The problem is that the first visit to an app pool needs to create a new w3wp.exe worker process which is slow because the app pool needs to be created, ASP.NET or another framework needs to be loaded, and then your application needs to be loaded. That can take a few seconds. Therefore I set that to 0 every chance I have, unless it’s for a server that hosts a lot of sites that don’t always need to be running.

In Dotnet Core 2.0 the Startup-constructor only expects a IConfiguration-parameter.

How to read hosting environment there? I store it in Program-class during ConfigureAppConfiguration (use full BuildWebHost instead of WebHost.CreateDefaultBuilder):

public class Program
{
    public static IHostingEnvironment HostingEnvironment { get; set; }

    public static void Main(string[] args)
    {
        // Build web host
        var host = BuildWebHost(args);

        host.Run();
    }

    public static IWebHost BuildWebHost(string[] args)
    {
        return new WebHostBuilder()
            .UseConfiguration(new ConfigurationBuilder()
                .SetBasePath(Directory.GetCurrentDirectory())
                .AddJsonFile("hosting.json", optional: true)
                .Build()
            )
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .ConfigureAppConfiguration((hostingContext, config) =>
            {
                var env = hostingContext.HostingEnvironment;

                // Assigning the environment for use in ConfigureServices
                HostingEnvironment = env; // <---

                config
                  .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
                  .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true, reloadOnChange: true);

                if (env.IsDevelopment())
                {
                    var appAssembly = Assembly.Load(new AssemblyName(env.ApplicationName));
                    if (appAssembly != null)
                    {
                        config.AddUserSecrets(appAssembly, optional: true);
                    }
                }

                config.AddEnvironmentVariables();

                if (args != null)
                {
                    config.AddCommandLine(args);
                }
            })
            .ConfigureLogging((hostingContext, builder) =>
            {
                builder.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
                builder.AddConsole();
                builder.AddDebug();
            })
            .UseIISIntegration()
            .UseDefaultServiceProvider((context, options) =>
            {
                options.ValidateScopes = context.HostingEnvironment.IsDevelopment();
            })
            .UseStartup<Startup>()
            .Build();
    }

Ant then reads it in ConfigureServices like this:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
    var isDevelopment = Program.HostingEnvironment.IsDevelopment();
}

MSBuild usually works, but I've run into difficulties before. You may have better luck with

devenv YourSolution.sln /Build 

Instead of merge, as others suggested, you can rebase one branch onto another:

git checkout BranchB
git rebase BranchA

This takes BranchB and rebases it onto BranchA, which effectively looks like BranchB was branched from BranchA, not master.

  //use fabs()
  double sum_primary_diagonal=0;
  double sum_secondary_diagonal=0;
  double difference = fabs(sum_primary_diagonal - sum_secondary_diagonal);

Well, there are different implementations for different browsers.

In my mind, the simplest and most elegant solution is using CSS calc(). Unfortunately, this method is unavailable in ie8 and less, and also not available in android browsers and mobile opera. If you're using separate methods for that, however, you can try this: http://jsfiddle.net/uRskD/

The markup:

<div id="header"></div>
<div id="body"></div>
<div id="footer"></div>

And the CSS:

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
}
#footer {
    background: #f0f;
    height: 20px;
}
#body {
    background: #0f0;
    min-height: calc(100% - 40px);
}

My secondary solution involves the sticky footer method and box-sizing. This basically allows for the body element to fill 100% height of its parent, and includes the padding in that 100% with box-sizing: border-box;. http://jsfiddle.net/uRskD/1/

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
}
#footer {
    background: #f0f;
    height: 20px;
    position: absolute;
    bottom: 0;
    left: 0;
    right: 0;
}
#body {
    background: #0f0;
    min-height: 100%;
    box-sizing: border-box;
    padding-top: 20px;
    padding-bottom: 20px;
}

My third method would be to use jQuery to set the min-height of the main content area. http://jsfiddle.net/uRskD/2/

html, body {
    height: 100%;
    margin: 0;
}
#header {
    background: #f0f;
    height: 20px;
}
#footer {
    background: #f0f;
    height: 20px;
}
#body {
    background: #0f0;
}

And the JS:

$(function() {
    headerHeight = $('#header').height();
    footerHeight = $('#footer').height();
    windowHeight = $(window).height();
   $('#body').css('min-height', windowHeight - headerHeight - footerHeight);
});

If you just want to find a match.

SELECT * FROM MyTable WHERE INSTR('word1 word2 word3',Column1)<>0

SQL Server :

CHARINDEX(Column1, 'word1 word2 word3', 1)<>0

To get exact match. Example (';a;ab;ac;',';b;') will not get a match.

SELECT * FROM MyTable WHERE INSTR(';word1;word2;word3;',';'||Column1||';')<>0

Yes, they are same for just int

and different for int*

With:

FILES = $(shell ls)

indented underneath all like that, it's a build command. So this expands $(shell ls), then tries to run the command FILES ....

If FILES is supposed to be a make variable, these variables need to be assigned outside the recipe portion, e.g.:

FILES = $(shell ls)
all:
        echo $(FILES)

Of course, that means that FILES will be set to "output from ls" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ... to avoid this, for efficiency and/or correctness.¹)

If FILES is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:

all:
        FILES="$(shell ls)"

However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:

        FILES="$(shell ls)"; echo $$FILES

This is all a bit silly since the shell will expand * (and other shell glob expressions) for you in the first place, so you can just:

        echo *

as your shell command.

Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls is not completely reliable (some details depend on file names and sometimes even the version of ls; some versions of ls attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard) and $(subst ...) to accomplish everything inside make itself (avoiding any "weird characters in file name" issues). (In sh scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0 to avoid tripping over blanks, newlines, control characters, and so on.)

¹The GNU Make documentation notes further that POSIX make added ::= assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make variants support ::= assignment, although GNU make does today, with the same meaning as :=, i.e., do the assignment right now with expansion.

Note that VAR := $(shell command args...) can also be spelled VAR != command args... in several make variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell) so using VAR != command args... is superior in both being shorter and working in more variants.

You might need to convert the decimal to money (or decimal(8,2)) to get that exact formatting. The convert method can take a third parameter that controls the formatting style:

convert(varchar, cast(price as money))       12345.67
convert(varchar, cast(price as money), 0)    12345.67
convert(varchar, cast(price as money), 1)    12,345.67

why not simply

public Date(){
    data = new int[]{0,0,0};
}

the reason you got the error is because int[] data = ... declares a new variable and hides the field data

however it should be noted that the contents of the array are already initialized to 0 (the default value of int)

1. Start a graphical vim session.
2. Do :e $MYGVIMRC Enter
3. Use the graphical font selection dialog to select a font.
4. Type :set guifont= Tab Enter.
5. Type G o to start a new line at the end of the file.
6. Type Ctrl+R followed by :.

The command in step 6 will insert the contents of the : special register which contains the last ex-mode command used. Here that will be the command from step 4, which has the properly formatted font name thanks to the tab completion of the value previously set using the GUI dialog.

If these are folders you want to ignore in a certain workspace, you can go to:

AppMenu > Preferences > Workspace Settings

Otherwise, if you want these folders to be ignored in all your workspaces, go to:

AppMenu > Preferences > User Settings

and add the following to your configuration:

//-------- Search configuration --------

// The folders to exclude when doing a full text search in the workspace.
"search.excludeFolders": [
    ".git",
    "node_modules",
    "bower_components",
    "path/to/other/folder/to/exclude"
],

The difference between workspace and user settings is explained in the customization docs

I ran into this when checking on a null or empty string

if (x == NULL || x == '') {

changed it to

if (is.null(x) || x == '') {

In object oriented design, the amount of coupling refers to how much the design of one class depends on the design of another class. In other words, how often do changes in class A force related changes in class B? Tight coupling means the two classes often change together, loose coupling means they are mostly independent. In general, loose coupling is recommended because it's easier to test and maintain.

If you don't know when data will be added to #data, you could set an interval to update the element's scrollTop to its scrollHeight every couple of seconds. If you are controlling when data is added, just call the internal of the following function after the data has been added.

window.setInterval(function() {
  var elem = document.getElementById('data');
  elem.scrollTop = elem.scrollHeight;
}, 5000);

var result = input.GroupBy(x=>x.F1,(key,g)=>g.OrderBy(e=>e.F2).First());

A simple example for writing multiple data to excel at a time. And also when you want to append data to a sheet on a written excel file (closed excel file).

When it is your first time writing to an excel. (Writing "df1" and "df2" to "1st_sheet" and "2nd_sheet")

import pandas as pd 
from openpyxl import load_workbook

df1 = pd.DataFrame([[1],[1]], columns=['a'])
df2 = pd.DataFrame([[2],[2]], columns=['b'])
df3 = pd.DataFrame([[3],[3]], columns=['c'])

excel_dir = "my/excel/dir"

with pd.ExcelWriter(excel_dir, engine='xlsxwriter') as writer:    
    df1.to_excel(writer, '1st_sheet')   
    df2.to_excel(writer, '2nd_sheet')   
    writer.save()    

After you close your excel, but you wish to "append" data on the same excel file but another sheet, let's say "df3" to sheet name "3rd_sheet".

book = load_workbook(excel_dir)
with pd.ExcelWriter(excel_dir, engine='openpyxl') as writer:
    writer.book = book
    writer.sheets = dict((ws.title, ws) for ws in book.worksheets)    

    ## Your dataframe to append. 
    df3.to_excel(writer, '3rd_sheet')  

    writer.save()     

Be noted that excel format must not be xls, you may use xlsx one.

Here's how to do it:

var myVideo = document.getElementById("my-video")    
myVideo.controls = false;

The limit of the length of an HTTP Get request is dependent on both the server and the client (browser) used, from 2kB - 8kB. The server should return 414 (Request-URI Too Long) status if an URI is longer than the server can handle.

Note Someone said that I could use state names instead of state values; in other words I could use xhr.readyState === xhr.DONE instead of xhr.readyState === 4 The problem is that Internet Explorer uses different state names so it's better to use state values.

For a Windows console app, you want to use SetConsoleCtrlHandler to handle CTRL+C and CTRL+BREAK.

Before writing below queries first get into your cmd or PowerShell

TYPE:
mongo             //To get into MongoDB shell
use <Your_dbName>      //For Creating or making use of existing db

To List All Collection Names use any one from below options :-

show collections  //output every collection
  OR
show tables
  OR
db.getCollectionNames() //shows all collections as a list

To show all collections content or data use below listed code which had been posted by Bruno_Ferreira.

var collections = db.getCollectionNames();
for(var i = 0; i< collections.length; i++) {    
   print('Collection: ' + collections[i]); // print the name of each collection
   db.getCollection(collections[i]).find().forEach(printjson); //and then print     the json of each of its elements
}

Instruct Gradle to download Android plugin from Maven Central repository.

You do it by pasting the following code at the beginning of the Gradle build file:

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.1'
    }
}

Replace version string 1.0.+ with the latest version. Released versions of Gradle plugin can be found in official Maven Repository or on MVNRepository artifact search.

Could you try this out?

=IIF((Fields!OpeningStock.Value=0) AND (Fields!GrossDispatched.Value=0) AND 
(Fields!TransferOutToMW.Value=0) AND (Fields!TransferOutToDW.Value=0) AND 
(Fields!TransferOutToOW.Value=0) AND (Fields!NetDispatched.Value=0) AND (Fields!QtySold.Value=0) 
AND (Fields!StockAdjustment.Value=0) AND (Fields!ClosingStock.Value=0),True,False)

Note: Setting Hidden to False will make the row visible

You can't modify a String in Java. They are immutable. All you can do is create a new string that is substring of the old string, minus the last character.

In some cases a StringBuffer might help you instead.

Convert.ChangeType() doesn't correctly handle nullable types or enumerations in .NET 2.0 BCL (I think it's fixed for BCL 4.0 though). Rather than make the outer implementation more complex, make the converter do more work for you. Here's an implementation I use:

public static class Converter
{
  public static T ConvertTo<T>(object value)
  {
    return ConvertTo(value, default(T));
  }

  public static T ConvertTo<T>(object value, T defaultValue)
  {
    if (value == DBNull.Value)
    {
      return defaultValue;
    }
    return (T) ChangeType(value, typeof(T));
  }

  public static object ChangeType(object value, Type conversionType)
  {
    if (conversionType == null)
    {
      throw new ArgumentNullException("conversionType");
    }

    // if it's not a nullable type, just pass through the parameters to Convert.ChangeType
    if (conversionType.IsGenericType && conversionType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
    {
      // null input returns null output regardless of base type
      if (value == null)
      {
        return null;
      }

      // it's a nullable type, and not null, which means it can be converted to its underlying type,
      // so overwrite the passed-in conversion type with this underlying type
      conversionType = Nullable.GetUnderlyingType(conversionType);
    }
    else if (conversionType.IsEnum)
    {
      // strings require Parse method
      if (value is string)
      {
        return Enum.Parse(conversionType, (string) value);          
      }
      // primitive types can be instantiated using ToObject
      else if (value is int || value is uint || value is short || value is ushort || 
           value is byte || value is sbyte || value is long || value is ulong)
      {
        return Enum.ToObject(conversionType, value);
      }
      else
      {
        throw new ArgumentException(String.Format("Value cannot be converted to {0} - current type is " +
                              "not supported for enum conversions.", conversionType.FullName));
      }
    }

    return Convert.ChangeType(value, conversionType);
  }
}

Then your implementation of GetQueryString<T> can be:

public static T GetQueryString<T>(string key)
{
    T result = default(T);
    string value = HttpContext.Current.Request.QueryString[key];

    if (!String.IsNullOrEmpty(value))
    {
        try
        {
            result = Converter.ConvertTo<T>(value);  
        }
        catch
        {
            //Could not convert.  Pass back default value...
            result = default(T);
        }
    }

    return result;
}

Please take care that the epoch time is in second and Date object accepts Long value which is in milliseconds. Hence you would have to multiply epoch value with 1000 to use it as long value . Like below :-

SimpleDateFormat sdf = new SimpleDateFormat("yyyyMMddhhmmss");
sdf.setTimeZone(TimeZone.getTimeZone(timeZone));
Long dateLong=Long.parseLong(sdf.format(epoch*1000));

Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.

TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.

Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):

When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the SynchronizationContext.Current which gets the synchronization context for the current thread. SynchronizationContext.Current is populated depending on the environment you are in. The GetAwaiter method of Task looks up for SynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.

When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because SynchronizationContext.Current is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!

Also, here are two great articles for you which are exactly for your question:

• The Perfect Recipe to Shoot Yourself in The Foot - Ending up with a Deadlock Using the C# 5.0 Asynchronous Language Features
• Asynchronous .NET Client Libraries for Your HTTP API and Awareness of async/await's Bad Effects

Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).

Hope this helps.

If you are using Java 6 or higher you can use wildcards of this form:

java -classpath ".;c:\mylibs\*;c:\extlibs\*" MyApp

If you would like to add all subdirectories: lib\a\, lib\b\, lib\c\, there is no mechanism for this in except:

java -classpath ".;c:\lib\a\*;c:\lib\b\*;c:\lib\c\*" MyApp

There is nothing like lib\*\* or lib\** wildcard for the kind of job you want to be done.

In SQL Management Studio you can:

1. Right click on the result set grid, select 'Save Result As...' and save in.

2. On a tool bar toggle 'Result to Text' button. This will prompt for file name on each query run.

If you need to automate it, use bcp tool.

Firstly a warning: you should never tinker with DOM that is managed by React, which you are doing by calling ReactDOM.render(<SampleComponent ... />);

With React, you should use SampleComponent directly in the main App.

var App = require('./App.js');
var SampleComponent = require('./SampleComponent.js');
ReactDOM.render(<App/>, document.body);

The content of your Component is irrelevant, but it should be used like this:

var App = React.createClass({
    render: function() {
        return (
            <div>
                <h1>App main component! </h1>
                <SampleComponent name="SomeName"/>
            </div>
        );
    }
});

You can then extend your app component to use a list.

var App = React.createClass({
    render: function() {
        var componentList = [
            <SampleComponent name="SomeName1"/>,
            <SampleComponent name="SomeName2"/>
        ]; // Change this to get the list from props or state
        return (
            <div>
                <h1>App main component! </h1>
                {componentList}
            </div>
        );
    }
});

I would really recommend that you look at the React documentation then follow the "Get Started" instructions. The time you spend on that will pay off later.

https://facebook.github.io/react/index.html

To check if one or more columns all exist, you can use set.issubset, as in:

if set(['A','C']).issubset(df.columns):
   df['sum'] = df['A'] + df['C']                

As @brianpck points out in a comment, set([]) can alternatively be constructed with curly braces,

if {'A', 'C'}.issubset(df.columns):

See this question for a discussion of the curly-braces syntax.

Or, you can use a list comprehension, as in:

if all([item in df.columns for item in ['A','C']]):

Here you go with word-wrap on Visual Studio Code.

I would add to the answer given by Siddarth Rout to say that the CountA call can be skipped by having Find return a Range object, instead of a row number, and then test the returned Range object to see if it is Nothing (blank worksheet).

Also, I would have my version of any LastRow procedure return a zero for a blank worksheet, then I can know it is blank.

Use kafka-consumer-groups.sh
