Constants can be declare outside of classes and use within your class. Otherwise the get property is a nice workaround

const MY_CONSTANT: string = "wazzup";

export class MyClass {

    public myFunction() {

        alert(MY_CONSTANT);
    }
}

As Joshua Bloch notes in Effective Java:

• Interfaces should only be used to define types,
• abstract classes don't prevent instanciability (they can be subclassed, and even suggest that they are designed to be subclassed).

You can use an Enum if all your constants are related (like planet names), put the constant values in classes they are related to (if you have access to them), or use a non instanciable utility class (define a private default constructor).

class SomeConstants
{
    // Prevents instanciation of myself and my subclasses
    private SomeConstants() {}

    public final static String TOTO = "toto";
    public final static Integer TEN = 10;
    //...
}

Then, as already stated, you can use static imports to use your constants.

Make certain to specify stringsAsFactors=FALSE when creating the dataframe:

> rm(list=ls())
> trigonometry <- data.frame(character(0), numeric(0), stringsAsFactors=FALSE)
> colnames(trigonometry) <- c("theta", "sin.theta")
> trigonometry
[1] theta     sin.theta
<0 rows> (or 0-length row.names)
> trigonometry[nrow(trigonometry) + 1, ] <- c("0", sin(0))
> trigonometry[nrow(trigonometry) + 1, ] <- c("pi/2", sin(pi/2))
> trigonometry
  theta sin.theta
1     0         0
2  pi/2         1
> typeof(trigonometry)
[1] "list"
> class(trigonometry)
[1] "data.frame"

Failing to use stringsAsFactors=FALSE when creating the dataframe will result in the following error when attempting to add the new row:

> trigonometry[nrow(trigonometry) + 1, ] <- c("0", sin(0))
Warning message:
In `[<-.factor`(`*tmp*`, iseq, value = "0") :

Asterisk (*) works with alias. Ex:

from pyspark.sql.functions import *

df1 = df1.alias('df1')
df2 = df2.alias('df2')

df1.join(df2, df1.id == df2.id).select('df1.*')

They are used in a similar way but they have a few differences. Here is a link to the TemplateBinding documentation: http://msdn.microsoft.com/en-us/library/ms742882.aspx

Note: Add -n or --dry-run to just check what it will do.

Short explanation:

If an algorithm is of T(g(n)), it means that the running time of the algorithm as n (input size) gets larger is proportional to g(n).

If an algorithm is of O(g(n)), it means that the running time of the algorithm as n gets larger is at most proportional to g(n).

Normally, even when people talk about O(g(n)) they actually mean T(g(n)) but technically, there is a difference.

More technically:

O(n) represents upper bound. T(n) means tight bound. O(n) represents lower bound.

f(x) = T(g(x)) iff f(x) = O(g(x)) and f(x) = O(g(x))

Basically when we say an algorithm is of O(n), it's also O(n²), O(n^1000000), O(2ⁿ), ... but a T(n) algorithm is not T(n²).

In fact, since f(n) = T(g(n)) means for sufficiently large values of n, f(n) can be bound within c₁g(n) and c₂g(n) for some values of c₁ and c₂, i.e. the growth rate of f is asymptotically equal to g: g can be a lower bound and and an upper bound of f. This directly implies f can be a lower bound and an upper bound of g as well. Consequently,

f(x) = T(g(x)) iff g(x) = T(f(x))

Similarly, to show f(n) = T(g(n)), it's enough to show g is an upper bound of f (i.e. f(n) = O(g(n))) and f is a lower bound of g (i.e. f(n) = O(g(n)) which is the exact same thing as g(n) = O(f(n))). Concisely,

f(x) = T(g(x)) iff f(x) = O(g(x)) and g(x) = O(f(x))

There are also little-oh and little-omega (?) notations representing loose upper and loose lower bounds of a function.

To summarize:

f(x) = O(g(x)) (big-oh) means that the growth rate of f(x) is asymptotically less than or equal to to the growth rate of g(x).

f(x) = O(g(x)) (big-omega) means that the growth rate of f(x) is asymptotically greater than or equal to the growth rate of g(x)

f(x) = o(g(x)) (little-oh) means that the growth rate of f(x) is asymptotically less than the growth rate of g(x).

f(x) = ?(g(x)) (little-omega) means that the growth rate of f(x) is asymptotically greater than the growth rate of g(x)

f(x) = T(g(x)) (theta) means that the growth rate of f(x) is asymptotically equal to the growth rate of g(x)

For a more detailed discussion, you can read the definition on Wikipedia or consult a classic textbook like Introduction to Algorithms by Cormen et al.

Looking for different solution, I found that

https://code.google.com/p/ude/

this solution is kinda heavy.

I needed some basic encoding detection, based on 4 first bytes and probably xml charset detection - so I've took some sample source code from internet and added slightly modified version of

http://lists.w3.org/Archives/Public/www-validator/2002Aug/0084.html

written for Java.

    public static Encoding DetectEncoding(byte[] fileContent)
    {
        if (fileContent == null)
            throw new ArgumentNullException();

        if (fileContent.Length < 2)
            return Encoding.ASCII;      // Default fallback

        if (fileContent[0] == 0xff
            && fileContent[1] == 0xfe
            && (fileContent.Length < 4
                || fileContent[2] != 0
                || fileContent[3] != 0
                )
            )
            return Encoding.Unicode;

        if (fileContent[0] == 0xfe
            && fileContent[1] == 0xff
            )
            return Encoding.BigEndianUnicode;

        if (fileContent.Length < 3)
            return null;

        if (fileContent[0] == 0xef && fileContent[1] == 0xbb && fileContent[2] == 0xbf)
            return Encoding.UTF8;

        if (fileContent[0] == 0x2b && fileContent[1] == 0x2f && fileContent[2] == 0x76)
            return Encoding.UTF7;

        if (fileContent.Length < 4)
            return null;

        if (fileContent[0] == 0xff && fileContent[1] == 0xfe && fileContent[2] == 0 && fileContent[3] == 0)
            return Encoding.UTF32;

        if (fileContent[0] == 0 && fileContent[1] == 0 && fileContent[2] == 0xfe && fileContent[3] == 0xff)
            return Encoding.GetEncoding(12001);

        String probe;
        int len = fileContent.Length;

        if( fileContent.Length >= 128 ) len = 128;
        probe = Encoding.ASCII.GetString(fileContent, 0, len);

        MatchCollection mc = Regex.Matches(probe, "^<\\?xml[^<>]*encoding[ \\t\\n\\r]?=[\\t\\n\\r]?['\"]([A-Za-z]([A-Za-z0-9._]|-)*)", RegexOptions.Singleline);
        // Add '[0].Groups[1].Value' to the end to test regex

        if( mc.Count == 1 && mc[0].Groups.Count >= 2 )
        {
            // Typically picks up 'UTF-8' string
            Encoding enc = null;

            try {
                enc = Encoding.GetEncoding( mc[0].Groups[1].Value );
            }catch (Exception ) { }

            if( enc != null )
                return enc;
        }

        return Encoding.ASCII;      // Default fallback
    }

It's enough to read probably first 1024 bytes from file, but I'm loading whole file.

The .ToLowerCase version is not going to be faster - it involves an extra string allocation (which must later be collected), etc.

Personally, I'd use

string.Equals(val, "astringvalue",  StringComparison.OrdinalIgnoreCase)

this avoids all the issues of culture-sensitive strings, but as a consequence it avoids all the issues of culture-sensitive strings. Only you know whether that is OK in your context.

Using the string.Equals static method avoids any issues with val being null.

You can try to do json.loads(), which will throw a ValueError if the string you pass can't be decoded as JSON.

In general, the "Pythonic" philosophy for this kind of situation is called EAFP, for Easier to Ask for Forgiveness than Permission.

Similar to getting the length of a dataframe, len(df), the following worked for pandas and blaze:

Total = sum(df['MyColumn'])

or alternatively

Total = sum(df.MyColumn)
print Total

Either move the xyz.h file somewhere else so the preprocessor can find it, or else change the #include statement so the preprocessor finds it where it already is.

Where the preprocessor looks for included files is described here. One solution is to put the xyz.h file in a folder where the preprocessor is going to find it while following that search pattern.

Alternatively you can change the #include statement so that the preprocessor can find it. You tell us the xyz.cxx file is is in the 'code' folder but you don't tell us where you've put the xyz.h file. Let's say your file structure looks like this...

<some folder>\xyz.h
<some folder>\code\xyz.cxx

In that case the #include statement in xyz.cxx should look something like this..

#include "..\xyz.h"

On the other hand let's say your file structure looks like this...

<some folder>\include\xyz.h
<some folder>\code\xyz.cxx

In that case the #include statement in xyz.cxx should look something like this..

#include "..\include\xyz.h"

Update: On the other other hand as @In silico points out in the comments, if you are using #include <xyz.h> you should probably change it to #include "xyz.h"

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

What you are trying to do can almost certainly be achieved with a set.

>>> x = set([1,2,3])
>>> x.add(2)
>>> x
set([1, 2, 3])
>>> x.add(4)
>>> x.add(4)
>>> x
set([1, 2, 3, 4])
>>> 

using a set's add method you can build your unique set of ids very quickly. Or if you already have a list

unique_ids = set(id_list)

as for getting your inputs in numeric form you can do something like

>>> ids = [int(n) for n in '350882 348521 350166\r\n'.split()]
>>> ids
[350882, 348521, 350166]

One can both fix the warning and use the timezone specified in settings.py, which might be different from UTC.

For example in my settings.py I have:

USE_TZ = True
TIME_ZONE = 'Europe/Paris'

Here is a solution; the advantage is that str(mydate) gives the correct time:

>>> from datetime import datetime
>>> from django.utils.timezone import get_current_timezone
>>> mydate = datetime.now(tz=get_current_timezone())
>>> mydate
datetime.datetime(2019, 3, 10, 11, 16, 9, 184106, 
    tzinfo=<DstTzInfo 'Europe/Paris' CET+1:00:00 STD>)
>>> str(mydate)
'2019-03-10 11:16:09.184106+01:00'

Another equivalent method is using make_aware, see dmrz post.

You could store by creating an object that hold a string value number to store in an array list. by example: BigInt objt = new BigInt("999999999999999999999999999999999999999999999999999");

objt is created by the constructor of BigInt class. Inside the class look like.

BigInt{

ArrayList<Integer> myNumber = new ArrayList <Integer>();        

public BigInt(){}

public BigInt(String number){ for(int i; i<number.length; i++){ myNumber.add(number.indexOf(i)); } }

}

I solved the problem by adding an fake autocomplete name for all inputs.

$("input").attr("autocomplete", "fake-name-disable-autofill");

Firstly, do you really have to have a mutable struct? They're almost always a bad idea. Likewise public fields. There are some very occasional contexts in which they're reasonable (usually both parts together, as with ValueTuple) but they're pretty rare in my experience.

Other than that, I'd just create a constructor taking the two bits of data:

class SomeClass
{

    struct MyStruct
    {
        private readonly string label;
        private readonly int id;

        public MyStruct (string label, int id)
        {
            this.label = label;
            this.id = id;
        }

        public string Label { get { return label; } }
        public string Id { get { return id; } }

    }

    static readonly IList<MyStruct> MyArray = new ReadOnlyCollection<MyStruct>
        (new[] {
             new MyStruct ("a", 1),
             new MyStruct ("b", 5),
             new MyStruct ("q", 29)
        });
}

Note the use of ReadOnlyCollection instead of exposing the array itself - this will make it immutable, avoiding the problem exposing arrays directly. (The code show does initialize an array of structs - it then just passes the reference to the constructor of ReadOnlyCollection<>.)

I got stuck exactly with the same error with psycopg2. It looks like I skipped a few steps while installing Python and related packages.

1. sudo apt-get install python-dev libpq-dev
2. Go to your virtual env
3. pip install psycopg2

(In your case you need to replace psycopg2 with the package you have an issue with.)

It worked seamlessly.

falsetru's solution is nice, but has a little bug:

Suppose original 'id' length was larger than 5 characters. When we then dump with the new 'id' (134 with only 3 characters) the length of the string being written from position 0 in file is shorter than the original length. Extra chars (such as '}') left in file from the original content.

I solved that by replacing the original file.

import json
import os

filename = 'data.json'
with open(filename, 'r') as f:
    data = json.load(f)
    data['id'] = 134 # <--- add `id` value.

os.remove(filename)
with open(filename, 'w') as f:
    json.dump(data, f, indent=4)

You can use this function to convert comma-delimited single character strings to list-

def stringtolist(x):
    mylist=[]
    for i in range(0,len(x),2):
        mylist.append(x[i])
    return mylist

I solved this issue by First, installing babel-eslint using npm

npm install babel-eslint --save-dev

Secondly, add this configuration in .eslintrc file

{
   "parser":"babel-eslint"
}

My understanding is that interfaces are not that necessary in dynamic languages like Python. In Java (or C++ with its abstract base class) interfaces are means for ensuring that e.g. you're passing the right parameter, able to perform set of tasks.

E.g. if you have observer and observable, observable is interested in subscribing objects that supports IObserver interface, which in turn has notify action. This is checked at compile time.

In Python, there is no such thing as compile time and method lookups are performed at runtime. Moreover, one can override lookup with __getattr__() or __getattribute__() magic methods. In other words, you can pass, as observer, any object that can return callable on accessing notify attribute.

This leads me to the conclusion, that interfaces in Python do exist - it's just their enforcement is postponed to the moment in which they are actually used

Requiring the http module was never necessary.

An additional import of http is not necessary in Express 3 or 4. Assigning the result of listen() is enough.

var server = require('express')();

server.get('/', function(req, res) {
  res.send("Hello Foo!");
});

var listener = server.listen(3000);
console.log('Your friendly Express server, listening on port %s', listener.address().port);
// Your friendly Express server, listening on port 3000

Again, this is tested in Express 3.5.1 & 4.0.0. Importing http was never necessary. The listen method returns an http server object. https://github.com/visionmedia/express/blob/master/lib/application.js#L531

Looking in /sys/class/net should be one way

Here's my script to test for a network connection other than the loop back. I use the below in another script that I have for periodically testing if my website is accessible. If it's NOT accessible a popup window alerts me to a problem.

The script below prevents me from receiving popup messages every five minutes whenever my laptop is not connected to the network.

#!/usr/bin/bash

# Test for network conection
for interface in $(ls /sys/class/net/ | grep -v lo);
do
  if [[ $(cat /sys/class/net/$interface/carrier) = 1 ]]; then OnLine=1; fi
done
if ! [ $OnLine ]; then echo "Not Online" > /dev/stderr; exit; fi

Note for those new to bash: The final 'if' statement tests if NOT [!] online and exits if this is the case. See man bash and search for "Expressions may be combined" for more details.

P.S. I feel ping is not the best thing to use here because it aims to test a connection to a particular host NOT test if there is a connection to a network of any sort.

P.P.S. The Above works on Ubuntu 12.04 The /sys may not exist on some other distros. See below:

Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, whereas many traditional UNIX and Unix-like operating systems use /sys as a symbolic link to the kernel source tree.[citation needed]

Do you just mean spaces or all whitespace?

For just spaces, use str_replace:

$string = str_replace(' ', '', $string);

For all whitespace (including tabs and line ends), use preg_replace:

$string = preg_replace('/\s+/', '', $string);

(From here).

Answering the question in your title, you can query sys.tables or sys.objects where type = 'U' to check for the existence of a table. You can also use OBJECT_ID('table_name', 'U'). If it returns a non-null value then the table exists:

IF (OBJECT_ID('dbo.My_Table', 'U') IS NULL)
BEGIN
    CREATE TABLE dbo.My_Table (...)
END

You can do the same for databases with DB_ID():

IF (DB_ID('My_Database') IS NULL)
BEGIN
    CREATE DATABASE My_Database
END

If you want to create the database and then start using it, that needs to be done in separate batches. I don't know the specifics of your case, but there shouldn't be many cases where this isn't possible. In a SQL script you can use GO statements. In an application it's easy enough to send across a new command after the database is created.

The only place that you might have an issue is if you were trying to do this in a stored procedure and creating databases on the fly like that is usually a bad idea.

If you really need to do this in one batch, you can get around the issue by using EXEC to get around the parsing error of the database not existing:

CREATE DATABASE Test_DB2

IF (OBJECT_ID('Test_DB2.dbo.My_Table', 'U') IS NULL)
BEGIN
    EXEC('CREATE TABLE Test_DB2.dbo.My_Table (my_id INT)')
END

EDIT: As others have suggested, the INFORMATION_SCHEMA.TABLES system view is probably preferable since it is supposedly a standard going forward and possibly between RDBMSs.

TCP keepalive and HTTP keepalive are very different concepts. In TCP, the keepalive is the administrative packet sent to detect stale connection. In HTTP, keepalive means the persistent connection state.

This is from TCP specification,

Keep-alive packets MUST only be sent when no data or acknowledgement packets have been received for the connection within an interval. This interval MUST be configurable and MUST default to no less than two hours.

As you can see, the default TCP keepalive interval is too long for most applications. You might have to add keepalive in your application protocol.

PsSuspend, as mentioned by Vadzim, even suspends/resumes a process by its name, not only by pid.

I use both PsSuspend and PsList (another tool from the PsTools suite) in a simple toggle script for the OneDrive process: if I need more bandwidth, I suspend the OneDrive sync, afterwards I resume the process by issuing the same mini script:

PsList -d onedrive|find/i "suspend" && PsSuspend -r onedrive || PsSuspend onedrive

PsSuspend command line utility from SysInternals suite. It suspends / resumes a process by its id.

Having attempted to follow Valros.nu's answer, i discovered that the sdk download is now bundeled with androind studio, in an 840MB exe installer.

As all you need for this particular program is the adb program, you can get this in a standalone installer from the xda guys:

http://forum.xda-developers.com/showthread.php?t=2317790

Note that you do not need to type adb.exe, simply type adb devices into the command prompt that is launched after install.

Also, i had to unplug and replug in my samsung s4 to get the remote debugging prompt to appear on the phone

The pythonic way to read a file and put every lines in a list:

from __future__ import with_statement #for python 2.5
with open('C:/path/numbers.txt', 'r') as f:
    lines = f.readlines()

Then, assuming that each lines contains a number,

numbers =[int(e.strip()) for e in lines]

If you want to open another application and it is not installed you can send it to the Google App Store to download

1. First create the openOtherApp method for example

   public static boolean openOtherApp(Context context, String packageName) {
       PackageManager manager = context.getPackageManager();
        try {
           Intent intent = manager.getLaunchIntentForPackage(packageName);
           if (intent == null) {
               //the app is not installed
               try {
                   intent = new Intent(Intent.ACTION_VIEW);
                   intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                   intent.setData(Uri.parse("market://details?id=" + packageName));
                   context.startActivity(intent);
               } catch (ActivityNotFoundException e) {
                   //throw new ActivityNotFoundException();
                   return false;
               }
   
            }
            intent.addCategory(Intent.CATEGORY_LAUNCHER);
            context.startActivity(intent);
            return true;
       } catch (ActivityNotFoundException e) {
           return false;
       }
   
   }
   

2.- Usage

openOtherApp(getApplicationContext(), "com.packageappname");

I think the following code piece may be helpful:

window.fnPureLog = function(sStatement, anyVariable) {
    if (arguments.length < 1) { 
        throw new Error('Arguments sStatement and anyVariable are expected'); 
    }
    if (typeof sStatement !== 'string') { 
        throw new Error('The type of sStatement is not match, please use string');
    }
    var oCallStackTrack = new Error();
    console.log(oCallStackTrack.stack.replace('Error', 'Call Stack:'), '\n' + sStatement + ':', anyVariable);
}

Execute the code:

window.fnPureLog = function(sStatement, anyVariable) {
    if (arguments.length < 1) { 
        throw new Error('Arguments sStatement and anyVariable are expected'); 
    }
    if (typeof sStatement !== 'string') { 
        throw new Error('The type of sStatement is not match, please use string');
    }
    var oCallStackTrack = new Error();
    console.log(oCallStackTrack.stack.replace('Error', 'Call Stack:'), '\n' + sStatement + ':', anyVariable);
}

function fnBsnCallStack1() {
    fnPureLog('Stock Count', 100)
}

function fnBsnCallStack2() {
    fnBsnCallStack1()
}

fnBsnCallStack2();

The log looks like this:

Call Stack:
    at window.fnPureLog (<anonymous>:8:27)
    at fnBsnCallStack1 (<anonymous>:13:5)
    at fnBsnCallStack2 (<anonymous>:17:5)
    at <anonymous>:20:1 
Stock Count: 100

Another possible reason – a few instances of git clients running at the same time. For example "git shell" + "GitHub Desktop", etc.

This happened to me, I was using "GitHub Desktop" as the main client and it was ignoring some new .gitignore settings: commit after commit:

1. You commit something.
2. Next, commit: it ignores .gitignore settings. Commit includes lots of temp files mentioned in the .gitignore.
3. Clear git cache; check whether .gitignore is UTF8; remove files -> commit -> move files back; skip 1 commit – nothing helped.

Reason: the Visual Studio Code editor was running in the background with the same opened repository. VS Code has built-in git control, and this makes some conflicts.

Solution: double-check multiple, hidden git clients and use only one git client at once, especially while clearing git cache.

Booleans are nothing but integers only, they are just type casted values like...

typedef signed char     BOOL; 

#define YES (BOOL)1
#define NO (BOOL)0

BOOL value = YES; 
NSLog(@"Bool value: %d",value);

If output is 1,YES otherwise NO

Yes. But not directly.

Simpler way

• You could post Vlookup() in one cell and use its address in where required. - This is perhaps the only direct way of using variables in Excel.

OR

• You could define Vlookup(reference)-10 as a wrapper function from within VBE Macros. Press Alt+f12 and use that function

From the docs:

_trackTrans() Sends both the transaction and item data to the Google Analytics server. This method should be called after _trackPageview(), and used in conjunction with the _addItem() and addTrans() methods. It should be called after items and transaction elements have been set up.

So, according to the docs, the items get sent when you call trackTrans(). Until you do, you can add items, but the transaction will not be sent.

Edit: Further reading led me here:

http://www.analyticsmarket.com/blog/edit-ecommerce-data

Where it clearly says you can start another transaction with an existing ID. When you commit it, the new items you listed will be added to that transaction.

I wrote this method to handle UTF8 arrays and JSON problems. It works fine with array (simple and multidimensional).

/**
 * Encode array from latin1 to utf8 recursively
 * @param $dat
 * @return array|string
 */
   public static function convert_from_latin1_to_utf8_recursively($dat)
   {
      if (is_string($dat)) {
         return utf8_encode($dat);
      } elseif (is_array($dat)) {
         $ret = [];
         foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);

         return $ret;
      } elseif (is_object($dat)) {
         foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);

         return $dat;
      } else {
         return $dat;
      }
   }
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);

These remaps work like a charm for me:

vmap <C-c> "*y     " Yank current selection into system clipboard
nmap <C-c> "*Y     " Yank current line into system clipboard (if nothing is selected)
nmap <C-v> "*p     " Paste from system clipboard

So, when I'm at visual mode, I select the lines I want and press Ctrl + c and then Ctrl + v to insert the text in the receiver file. You could use "*y as well, but I think this is hard to remember sometimes.

This is also useful to copy text from Vim to clipboard.

I have perfect answer for all this : I tried so many solution not able to get finally myself able to manage , please find detail answer below:

       $.ajax({
            traditional: true,
            url: "/Conroller/MethodTest",
            type: "POST",
            contentType: "application/json; charset=utf-8",
            data:JSON.stringify( 
               [
                { id: 1, color: 'yellow' },
                { id: 2, color: 'blue' },
                { id: 3, color: 'red' }
                ]),
            success: function (data) {
                $scope.DisplayError(data.requestStatus);
            }
        });

Controler

public class Thing
{
    public int id { get; set; }
    public string color { get; set; }
}

public JsonResult MethodTest(IEnumerable<Thing> datav)
    {
   //now  datav is having all your values
  }

You can try to use this

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<item>
    <shape
        android:innerRadius="0dp"
        android:shape="ring"
        android:thicknessRatio="2"
        android:useLevel="false" >
        <solid android:color="@color/button_blue_two" />
    </shape>
</item>

and you don't have to bother the width and height aspect ratio if you are using this for a textview

You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.

Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/

Because these days ASP.NET is open source, you can find it on GitHub: AspNet.Identity 3.0 and AspNet.Identity 2.0.

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

The command you are seeking is comm. eg:-

comm -12 1.sorted.txt 2.sorted.txt

Here:

-1 : suppress column 1 (lines unique to 1.sorted.txt)

-2 : suppress column 2 (lines unique to 2.sorted.txt)

{ "keys": ["f12"], "command": "reindent", "args": {"single_line": false} }

If you are experiencing the OP's problem where your cookies have been set using JavaScript - for example:

document.cookie = "my_cookie_name=my_cookie_value; expires=Thu, 11 Jun 2070 11:11:11 UTC; path=/";

you could instead use:

document.cookie = "my_cookie_name=my_cookie_value; expires=Thu, 11 Jun 2070 11:11:11 UTC; path=/; SameSite=None; Secure";

It worked for me. More info here.

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

Or add "sort name" to list alphabetically

Get-ADPrincipalGroupMembership username | select name | sort name

you just open command prompt, then enter in c:/>('cd../../') then npm install -g cordova

This formula will do the job:

=INDEX(G:G,MATCH(FALSE,ISERROR(SEARCH(H1,G:G)),0)+3)

you need to enter it as an array formula, i.e. press Ctrl-Shift-Enter. It assumes that the substring you're searching for is in cell H1.

DateTime.Today represents the current system date with the time part set to 00:00:00

DateTime.Now represents the current system date and time

First you have to locate the frame id and define it in a WebElement

For ex:- WebElement fr = driver.findElementById("id");

Then switch to the frame using this code:- driver.switchTo().frame("Frame_ID");

An example script:-

WebElement fr = driver.findElementById("theIframe");

driver.switchTo().frame(fr);

Then to move out of frame use:- driver.switchTo().defaultContent();

**Replacing  href attribut value to other**

  </div>

 <!--Remove first default Link from href attribut -->
<script>
     Remove first default Link from href attribut
    $(".cpt a").removeAttr("href");
    
    Add  Link to same href attribut
    var testurl= $(".test").find("a").attr("href");
    $(".test a").attr('href', testurl);
</script>

Because my edits to the above were rejected (did any of you actually try?), here's what you really need to make this work:

Windows (And Mac Office 2011+):

• Unix Timestamp = (Excel Timestamp - 25569) * 86400
• Excel Timestamp = (Unix Timestamp / 86400) + 25569

MAC OS X (pre Office 2011):

• Unix Timestamp = (Excel Timestamp - 24107) * 86400
• Excel Timestamp = (Unix Timestamp / 86400) + 24107

I've tried a some of the solutions in this thread, and unfortunately, I found some of them to be cumbersome (i.e. requiring excessive effort when doing something non-trivial) and inelegant. Consequently, I thought I'd throw my preferred solution, web2py HTML helper objects, into the mix.

First, install the the standalone web2py module:

pip install web2py

Unfortunately, the above installs an extremely antiquated version of web2py, but it'll be good enough for this example. The updated source is here.

Import web2py HTML helper objects documented here.

from gluon.html import *

Now, you can use web2py helpers to generate XML/HTML.

words = ['this', 'is', 'my', 'item', 'list']
# helper function
create_item = lambda idx, word: LI(word, _id = 'item_%s' % idx, _class = 'item')
# create the HTML
items = [create_item(idx, word) for idx,word in enumerate(words)]
ul = UL(items, _id = 'my_item_list', _class = 'item_list')
my_div = DIV(ul, _class = 'container')

>>> my_div

<gluon.html.DIV object at 0x00000000039DEAC8>

>>> my_div.xml()
# I added the line breaks for clarity
<div class="container">
   <ul class="item_list" id="my_item_list">
      <li class="item" id="item_0">this</li>
      <li class="item" id="item_1">is</li>
      <li class="item" id="item_2">my</li>
      <li class="item" id="item_3">item</li>
      <li class="item" id="item_4">list</li>
   </ul>
</div>

svn:// doesn't talk http, therefor there's nothing a http proxy could do.

Any reason why http doesn't work? Have you considered https? If you really need it, you probably have to have port 3690 opened in your firewall.

You can use Amazon Corretto. It is free to use multiplatform, production-ready distribution of the OpenJDK. It comes with long-term support that will include performance enhancements and security fixes. Check the installation instructions here.

You can also check Zulu from Azul.

One more thing I like to highlight here is both Amazon Corretto and Zulu are TCK Compliant. You can see the OpenJDK builds comparison here and here.

Just call it

Make sure it will be found (path).

If you want the head command, one easy way to get it is to install Cygwin. Then you'll have all the UNIX tools at your disposal.

If that isn't a good solution, then you can try using findstr and do a search for the end-of-line indicator.

findstr on MSDN: http://technet.microsoft.com/en-us/library/bb490907.aspx

Although there are answers to this your questions but because I was once a victim of this problem and after few search online i was unable to solve it but my fellow hub mate helped me and i feel i should share. Examples explained below.

Folders: web-projects/project1/imgs-journey.png

background-image:url(../imgs/journey.png);
background-repeat:no-repeat;
background-size:cover;

My major points is the dots there if you noticed my journey.png is located inside an imgs folder of another folder so you're to add the dot according to the numbers folders where your image is stored. In my case my journey.png image is saved in two folders that's why two dot is used, so i think this may be the problem of background images not showing sometimes in our codes. Thanks.

You can use @@ROWCOUNT to check whether row should be inserted or updated:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'
if @@ROWCOUNT = 0
insert into table1(id, name, itemname, itemcatName, itemQty)
values('val1', 'val2', 'val3', 'val4', 'val5')

in this case if update fails, the new row will be inserted

In Pandas, I like to use the shape attribute to get number of rows.

df[df.A > 0].shape[0]

gives the number of rows matching the condition A > 0, as desired.

Try using this command. See the example given below:

df.loc[len(df)] = ['Product 9',99,9.99,8.88,1.11]

df

Since I'm separating page elements definitions and page test scenarios using an already-found IWebElement for visibility, it could be done like this:

public static void WaitForElementToBecomeVisibleWithinTimeout(IWebDriver driver, IWebElement element, int timeout)
{
    new WebDriverWait(driver, TimeSpan.FromSeconds(timeout)).Until(ElementIsVisible(element));
}

private static Func<IWebDriver, bool> ElementIsVisible(IWebElement element)
{
    return driver => {
        try
        {
            return element.Displayed;
        }
        catch(Exception)
        {
            // If element is null, stale or if it cannot be located
            return false;
        }
    };
}

To ensure that a cell will return a date value and not just a string that looks like a date, first you must set the NumberFormat property to a Date format, then put a real date into the cell's content.

Sub test_date_or_String()
 Set c = ActiveCell
 c.NumberFormat = "@"
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a String
 c.NumberFormat = "m/d/yyyy"
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is still a String
 c.Value = CDate("03/04/2014")
   Debug.Print c.Value & " is a " & TypeName(c.Value) 'C is a date    
End Sub

You can use a converter or create new property in your ViewModel like that:

public bool CanDoIt
{
    get
    {
        return !string.IsNullOrEmpty(SomeField);
    }
}

and use it:

<DataTrigger Binding="{Binding SomeField}" Value="{Binding CanDoIt}">

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

In python, use and instead of && like this:

#!/usr/bin/python
foo = True;
bar = True;
if foo and bar:
    print "both are true";

This prints:

both are true

I think what you want is this:

ASP.NET MVC1

Html.ActionLink(article.Title, 
                "Login",  // <-- Controller Name.
                "Item",   // <-- ActionMethod
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string controllerName,
                                string actionName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC2

two arguments have been switched around

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { id = article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This uses the following method ActionLink signature:

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string actionName,
                                string controllerName,
                                object values, 
                                object htmlAttributes)

ASP.NET MVC3+

arguments are in the same order as MVC2, however the id value is no longer required:

Html.ActionLink(article.Title, 
                "Item",   // <-- ActionMethod
                "Login",  // <-- Controller Name.
                new { article.ArticleID }, // <-- Route arguments.
                null  // <-- htmlArguments .. which are none. You need this value
                      //     otherwise you call the WRONG method ...
                      //     (refer to comments, below).
                )

This avoids hard-coding any routing logic into the link.

 <a href="/Item/Login/5">Title</a> 

This will give you the following html output, assuming:

1. article.Title = "Title"
2. article.ArticleID = 5
3. you still have the following route defined

. .

routes.MapRoute(
    "Default",     // Route name
    "{controller}/{action}/{id}",                           // URL with parameters
    new { controller = "Home", action = "Index", id = "" }  // Parameter defaults
);

The most voted answer has got already defined [String] function body. I was looking for the solution to rename already declared function's name and finally after an hour of struggling I've dealt with it. It:

• takes the alredy declared function
• parses it to [String] with .toString() method
• then overwrites the name (of named function) or appends the new one (when anonymous) between function and (
• then creates the new renamed function with new Function() constructor

function nameAppender(name,fun){_x000D_
  const reg = /^(function)(?:\s*|\s+([A-Za-z0-9_$]+)\s*)(\()/;_x000D_
  return (new Function(`return ${fun.toString().replace(reg,`$1 ${name}$3`)}`))();_x000D_
}_x000D_
_x000D_
//WORK FOR ALREADY NAMED FUNCTIONS:_x000D_
function hello(name){_x000D_
  console.log('hello ' + name);_x000D_
}_x000D_
_x000D_
//rename the 'hello' function_x000D_
var greeting = nameAppender('Greeting', hello); _x000D_
_x000D_
console.log(greeting); //function Greeting(name){...}_x000D_
_x000D_
_x000D_
//WORK FOR ANONYMOUS FUNCTIONS:_x000D_
//give the name for the anonymous function_x000D_
var count = nameAppender('Count',function(x,y){ _x000D_
  this.x = x;_x000D_
  this.y = y;_x000D_
  this.area = x*y;_x000D_
}); _x000D_
_x000D_
console.log(count); //function Count(x,y){...}

The DATEADD() function adds or subtracts a specified time interval from a date.

DATEADD(datepart,number,date)

datepart(interval) can be hour, second, day, year, quarter, week etc; number (increment int); date(expression smalldatetime)

For example if you want to add 30 days to current date you can use something like this

 select dateadd(dd, 30, getdate())

To Substract 30 days from current date

select dateadd(dd, -30, getdate())

If none of these work, try getBaseContext(), instead of context or this.

1. --save-dev (only used in the development, not in production)

2. --save (production dependencies)

3. --global or -g (used globally i.e can be used anywhere in our local system)

I summarize the answers found in that article:

http://www.quora.com/How-does-MongoDB-compare-to-CouchDB-What-are-the-advantages-and-disadvantages-of-each

MongoDB: Better querying, data storage in BSON (faster access), better data consistency, multiple collections

CouchDB: Better replication, with master to master replication and conflict resolution, data storage in JSON (human-readable, better access through REST services), querying through map-reduce.

So in conclusion, MongoDB is faster, CouchDB is safer.

Sushicutta's steps 4-7 can be skipped by adding the following line to step 3:

-Dcom.sun.management.jmxremote.rmi.port=<same port as jmx-remote-port>

e.g. Add to start up parameters:

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=12345
-Dcom.sun.management.jmxremote.rmi.port=12345
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.local.only=false
-Djava.rmi.server.hostname=localhost

For the port forwarding, connect using:

ssh -L 12345:localhost:12345 <username>@<host>

if your host is a stepping stone, simply chain the port forward by running the following on the step stone after the above:

ssh -L 12345:localhost:12345 <username>@<host2>

Mind that the hostname=localhost is needed to make sure the jmxremote is telling the rmi connection to use the tunnel. Otherwise it might try to connect directy and hit the firewall.

@Autowired to autowire(or search) by-type
@Qualifier to autowire(or search) by-name
Other alternate option for @Qualifier is @Primary

@Component
@Qualifier("beanname")
public class A{}

public class B{

//Constructor
@Autowired  
public B(@Qualifier("beanname")A a){...} //  you need to add @autowire also 

//property
@Autowired
@Qualifier("beanname")
private A a;

}

//If you don't want to add the two annotations, we can use @Resource
public class B{

//property
@Resource(name="beanname")
private A a;

//Importing properties is very similar
@Value("${property.name}")  //@Value know how to interpret ${}
private String name;
}

A workaround to consider in a pinch:

1. save a copy of the excel file, modify the column to format type 'text'
2. copy the column values and paste to a text editor, save the file (call it tmp.txt).
3. modify the data in the text file to start and end with a character so that the SQL Server import mechanism will recognize as text. If you have a fancy editor, use included tools. I use awk in cygwin on my windows laptop. For example, I start end end the column value with a single quote, like "$ awk '{print "\x27"$1"\x27"}' ./tmp.txt > ./tmp2.txt"
4. copy and paste the data from tmp2.txt over top of the necessary column in the excel file, and save the excel file
5. run the sql server import for your modified excel file... be sure to double check the data type chosen by the importer is not numeric... if it is, repeat the above steps with a different set of characters

The data in the database will have the quotes once the import is done... you can update the data later on to remove the quotes, or use the "replace" function in your read query, such as "replace([dbo].[MyTable].[MyColumn], '''', '')"

Text files in Windows don't have a format. There's an unofficial convention that if the file starts with the BOM codepoint in UTF-8 format that it's UTF-8, but that convention isn't universally supported. That would be the 3 byte sequence "\xef\xbf\xbe", i.e. ￾ in the Latin-1 character set.

This is often achieved by throwing an error from the current context; then analyzing error object for properties like lineNumber and fileName (which some browsers have)

function getErrorObject(){
  try { throw Error('') } catch(err) { return err; }
}

var err = getErrorObject();

err.fileName;
err.lineNumber; // or `err.line` in WebKit

Don't forget that callee.caller property is deprecated (and was never really in ECMA 3rd ed. in the first place).

Also remember that function decompilation is specified to be implementation dependent and so might yield quite unexpected results. I wrote about it here and here.

Just try to create the marker and set the draggable property to true. The code will be something as follows:

Marker = new google.maps.Marker({
    position: latlon,
    map: map,            
    draggable: true,
    title: "Drag me!"
});

I hope this helps!

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

You should try this. It starts the program with no window. It actually flashes up for a second but goes away fairly quickly.

start "name" /B myprogram.exe param1

If you want to combine a Map for efficient retrieval with a SortedMap, you may use the ConcurrentSkipListMap.

Of course, you need the key to be the value used for sorting.

Try this- In this example Original color is green and mouseover color will be DarkGoldenrod

        <Style TargetType="{x:Type Button}">
            <Setter Property="Background" Value="Green"/>
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="{x:Type Button}">
                        <Border Background="{TemplateBinding Background}">
                            <ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center"/>
                        </Border>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="DarkGoldenrod"/>
                </Trigger>

Tried out most of the solutions here and what helped me was cleaning the build folder in XCode using: Product - > Clean and rebuild the project

Try mapping it. Try placing this code in your UserControl:

public event EventHandler ValueChanged {
  add { numericUpDown1.ValueChanged += value; }
  remove { numericUpDown1.ValueChanged -= value; }
}

then your UserControl will have the ValueChanged event you normally see with the NumericUpDown control.

function getDateTime(unixTimeStamp) {

    var d = new Date(unixTimeStamp);
    var h = (d.getHours().toString().length == 1) ? ('0' + d.getHours()) : d.getHours();
    var m = (d.getMinutes().toString().length == 1) ? ('0' + d.getMinutes()) : d.getMinutes();
    var s = (d.getSeconds().toString().length == 1) ? ('0' + d.getSeconds()) : d.getSeconds();

    var time = h + '/' + m + '/' + s;

    return time;
}

var myTime = getDateTime(1435986900000);
console.log(myTime); // output 01/15/00

Using Spring context 5.0 I have successfully achieved loading correct property file based on system environment via the following annotation

@PropertySources({
    @PropertySource("classpath:application.properties"),
    @PropertySource("classpath:application-${MYENV:test}.properties")})

Here MYENV value is read from system environment and if system environment is not present then default test environment property file will be loaded, if I give a wrong MYENV value - it will fail to start the application.

Note: for each profile, you want to maintain - you will need to make an application-[profile].property file and although I used Spring context 5.0 & not Spring boot - I believe this will also work on Spring 4.1

What you'll see sometimes is the following:

class Abstract1( object ):
    """Some description that tells you it's abstract,
    often listing the methods you're expected to supply."""
    def aMethod( self ):
        raise NotImplementedError( "Should have implemented this" )

Because Python doesn't have (and doesn't need) a formal Interface contract, the Java-style distinction between abstraction and interface doesn't exist. If someone goes through the effort to define a formal interface, it will also be an abstract class. The only differences would be in the stated intent in the docstring.

And the difference between abstract and interface is a hairsplitting thing when you have duck typing.

Java uses interfaces because it doesn't have multiple inheritance.

Because Python has multiple inheritance, you may also see something like this

class SomeAbstraction( object ):
    pass # lots of stuff - but missing something

class Mixin1( object ):
    def something( self ):
        pass # one implementation

class Mixin2( object ):
    def something( self ):
        pass # another

class Concrete1( SomeAbstraction, Mixin1 ):
    pass

class Concrete2( SomeAbstraction, Mixin2 ):
    pass

This uses a kind of abstract superclass with mixins to create concrete subclasses that are disjoint.

• inline-block is of no use in this scenario

SOLUTION

• word-break: normal|break-all|keep-all|break-word|initial|inherit;
  Simple Answer to your doubt is Use above and make sure white-space: nowrap nowhere used.

NOTE FOR BETTER UNDERSTANDING:

• word-wrap/overflow-wrap is used to break words that overflow their container

• word-break property breaks all words at the end of a line, even those that would normally wrap onto another line and wouldn’t overflow their container.

• word-wrap is the historic and nonstandard property. It has been renamed to overflow-wrap but remains an alias, browsers must support in future. Many browsers (especially the old ones) don’t support overflow-wrap and require word-wrap as a fallback (which is supported by all).

• If you want to please the W3C you should consider associate both in your CSS. If you don’t, using word-wrap alone is just fine.

If you are sure you want to remove all commit history, simply delete the .git directory in your project root (note that it's hidden). Then initialize a new repository in the same folder and link it to the GitHub repository:

git init
git remote add origin [email protected]:user/repo

now commit your current version of code

git add *
git commit -am 'message'

and finally force the update to GitHub:

git push -f origin master

However, I suggest backing up the history (the .git folder in the repository) before taking these steps!

There is no native way of doing this.

The Redis command documentation contains no native commands for getting the key and value of multiple keys.

The most native way of doing this would be to load a lua script into your redis using the SCRIPT LOAD command or the EVAL command.

Bash Haxx solution

A workaround would be to use some bash magic, like this:

echo 'keys YOURKEY*' | redis-cli | sed 's/^/get /' | redis-cli 

This will output the data from all the keys which begin with YOURKEY

Note that the keys command is a blocking operation and should be used with care.

"A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered."

Not so. The purpose of a destructor is to allow the item that registered the listeners to unregister them. Once an object has no other references to it, it will be garbage collected.

For instance, in AngularJS, when a controller is destroyed, it can listen for a destroy event and respond to it. This isn't the same as having a destructor automatically called, but it's close, and gives us the opportunity to remove listeners that were set when the controller was initialized.

// Set event listeners, hanging onto the returned listener removal functions
function initialize() {
    $scope.listenerCleanup = [];
    $scope.listenerCleanup.push( $scope.$on( EVENTS.DESTROY, instance.onDestroy) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.SUCCESS, instance.onCreateUserResponse ) );
    $scope.listenerCleanup.push( $scope.$on( AUTH_SERVICE_RESPONSES.CREATE_USER.FAILURE, instance.onCreateUserResponse ) );
}

// Remove event listeners when the controller is destroyed
function onDestroy(){
    $scope.listenerCleanup.forEach( remove => remove() );
}

Flying Saucer xhtmlrenderer repeats the THEAD on every page of PDF output, if you add the following to your CSS:

(It works at least since the R8 release.)

Here are a few ways of removing a single ' from a string in python.

• str.replace

  replace is usually used to return a string with all the instances of the substring replaced.

  "A single ' char".replace("'","")
  

• str.translate

  In Python 2

  To remove characters you can pass the first argument to the funstion with all the substrings to be removed as second.

  "A single ' char".translate(None,"'")
  

  In Python 3

  You will have to use str.maketrans

  "A single ' char".translate(str.maketrans({"'":None}))
  

• re.sub

  Regular Expressions using re are even more powerful (but slow) and can be used to replace characters that match a particular regex rather than a substring.

  re.sub("'","","A single ' char")
  

Other Ways

There are a few other ways that can be used but are not at all recommended. (Just to learn new ways). Here we have the given string as a variable string.

• Using list comprehension

  ''.join([c for c in string if c != "'"])
  

• Using generator Expression

  ''.join(c for c in string if c != "'")
  

Another final method can be used also (Again not recommended - works only if there is only one occurrence )

• Using list call along with remove and join.

  x = list(string)
  x.remove("'")
  ''.join(x)

you need to put it after wp_head(); Because that loads your jQuery and you need to load jQuery first and then your js

The make uses the $ for its own variable expansions. E.g. single character variable $A or variable with a long name - ${VAR} and $(VAR).

To put the $ into a command, use the $$, for example:

all:
  @echo "Please execute next commands:"
  @echo 'setenv PATH /usr/local/greenhills/mips5/linux86:$$PATH'

Also note that to make the "" and '' (double and single quoting) do not play any role and they are passed verbatim to the shell. (Remove the @ sign to see what make sends to shell.) To prevent the shell from expanding $PATH, second line uses the ''.

First of all Arrays class is an utility class which contains no. of utility methods to operate on Arrays (thanks to Arrays class otherwise we would have needed to create our own methods to act on Array objects)

asList() method:

1. asList method is one of the utility methods of Array class ,it is static method thats why we can call this method by its class name (like Arrays.asList(T...a) )
2. Now here is the twist, please note that this method doesn't create new ArrayList object, it just returns a List reference to existing Array object(so now after using asList method, two references to existing Array object gets created)
3. and this is the reason, all methods that operate on List object , may NOT work on this Array object using List reference like for example, Arrays size is fixed in length, hence you obviously can not add or remove elements from Array object using this List reference (like list.add(10) or list.remove(10); else it will throw UnsupportedOperationException)
4. any change you are doing using list reference will be reflected in exiting Arrays object ( as you are operating on existing Array object by using list reference)

In first case you are creating a new Arraylist object (in 2nd case only reference to existing Array object is created but not a new ArrayList object) ,so now there are two different objects one is Array object and another is ArrayList object and no connection between them ( so changes in one object will not be reflected/affected in another object ( that is in case 2 Array and Arraylist are two different objects)

case 1:

Integer [] ia = {1,2,3,4};
System.out.println("Array : "+Arrays.toString(ia));
List<Integer> list1 = new ArrayList<Integer>(Arrays.asList(ia));  // new ArrayList object is created , no connection between existing Array Object
list1.add(5);
list1.add(6);
list1.remove(0);
list1.remove(0);
System.out.println("list1 : "+list1);
System.out.println("Array : "+Arrays.toString(ia));

case 2:

Integer [] ia = {1,2,3,4};
System.out.println("Array : "+Arrays.toString(ia));
List<Integer> list2 = Arrays.asList(ia); // creates only a (new ) List reference to existing Array object (and NOT a new ArrayList Object)
//  list2.add(5); //  it will throw java.lang.UnsupportedOperationException - invalid operation (as Array size is fixed)
list2.set(0,10);  // making changes in existing Array object using List reference - valid 
list2.set(1,11); 
ia[2]=12;     // making changes in existing Array object using Array reference - valid
System.out.println("list2 : "+list2);
System.out.println("Array : "+Arrays.toString(ia));

Empty slice and nil slice are initialized differently in Go:

var nilSlice []int 
emptySlice1 := make([]int, 0)
emptySlice2 := []int{}

fmt.Println(nilSlice == nil)    // true
fmt.Println(emptySlice1 == nil) // false
fmt.Println(emptySlice2 == nil) // false

As for all three slices, len and cap are 0.

How and where is app.run() used? After module definition or after app.config(), after app.controller()?

Where:

In your package.js E.g. /packages/dashboard/public/controllers/dashboard.js

How:

Make it look like this

var app = angular.module('mean.dashboard', ['ui.bootstrap']);

app.controller('DashboardController', ['$scope', 'Global', 'Dashboard',
    function($scope, Global, Dashboard) {
        $scope.global = Global;
        $scope.package = {
            name: 'dashboard'
        };
        // ...
    }
]);

app.run(function(editableOptions) {
    editableOptions.theme = 'bs3'; // bootstrap3 theme. Can be also 'bs2', 'default'
});

@Override
    protected void onPause() {
        super.onPause();
        System.exit(0);
    }

document.getElementById("serverTime").innerHTML = ...;

If using 3rd Pary Libaries is ok cyclops-react defines Lazy extended collections with this functionality built in. For example we could simply write

ListX myListToParse;

ListX myFinalList = myListToParse.filter(elt -> elt != null) .map(elt -> doSomething(elt));

myFinalList is not evaluated until first access (and there after the materialized list is cached and reused).

[Disclosure I am the lead developer of cyclops-react]

In newer versions of OS X (especially Yosemite, EL Capitan), Apple has removed Java support for security reasons. To fix this you have to do the following.

1. Download Java for OS X 2015-001 from this link: https://support.apple.com/kb/dl1572?locale=en_US

2. Mount the disk image file and install Java 6 runtime for OS X.

   After this you should not be seeing any of the below messages:

   - Unable to find any JVMs matching version "(null)"

   - No Java runtime present, try --request to install.

   This should resolve the issue for the pop-up shown below:

Big task, chances are you shouldn't reinvent the wheel rather using an existing wheel (such as paypal).

However, if you insist on continuing. Start small, you can use a credit card processing facility (Moneris, Authorize.NET) to process credit cards. Most providers have an API you can use. Be wary that you may need to use different providers depending on the card type (Discover, Visa, Amex, Mastercard) and Country (USA, Canada, UK). So build it so that you can communicate with multiple credit card processing APIs.

Security is essential if you are storing credit cards and payment details. Ensure that you are encrypting things properly.

Again, don't reinvent the wheel. You are better off using an existing provider and focussing your development attention on solving an problem that can't easily be purchase.

You can use Object.prototype.toString to easily check if an object is an Error, which will work for different frames as well.

function isError(obj){
    return Object.prototype.toString.call(obj) === "[object Error]";
}

function isError(obj){
    return Object.prototype.toString.call(obj) === "[object Error]";
}
console.log("Error:", isError(new Error));
console.log("RangeError:", isError(new RangeError));
console.log("SyntaxError:", isError(new SyntaxError));
console.log("Object:", isError({}));
console.log("Array:", isError([]));

This behavior is guaranteed by the ECMAScript Language Specification.

Object.prototype.toString:

When the toString method is called, the following steps are taken:

1. If the this value is undefined, return "[object Undefined]".
2. If the this value is null, return "[object Null]".
3. Let O be the result of calling ToObject passing the this value as the argument.
4. Let class be the value of the [[Class]] internal property of O.
5. Return the String value that is the result of concatenating the three Strings "[object ", class, and "]".

Properties of Error Instances:

Error instances inherit properties from the Error prototype object and their [[Class]] internal property value is "Error". Error instances have no special properties.

You can try the code

<View
    style={{
      alignItems: 'center',
      justifyContent: 'center'
    }}
  >
    <View
      style={{
        position: 'absolute',
        margin: 'auto',
        width: 50,
        height: 50
      }}
    />
  </View>

In addition to perfect Riceball LEE's example of adding a new element-directive

newElement = $compile("<div my-directive='n'></div>")($scope)
$element.parent().append(newElement)

Adding a new attribute-directive to existed element could be done using this way:

Let's say you wish to add on-the-fly my-directive to the span element.

template: '<div>Hello <span>World</span></div>'

link: ($scope, $element, $attrs) ->

  span = $element.find('span').clone()
  span.attr('my-directive', 'my-directive')
  span = $compile(span)($scope)
  $element.find('span').replaceWith span

Hope that helps.

You say you have an index, the explain says otherwise. However, if you really do, this is how to continue:

If you have an index on the column, and MySQL decides not to use it, it may by because:

1. There's another index in the query MySQL deems more appropriate to use, and it can use only one. The solution is usually an index spanning multiple columns if their normal method of retrieval is by value of more then one column.
2. MySQL decides there are to many matching rows, and thinks a tablescan is probably faster. If that isn't the case, sometimes an ANALYZE TABLE helps.
3. In more complex queries, it decides not to use it based on extremely intelligent thought-out voodoo in the query-plan that for some reason just not fits your current requirements.

In the case of (2) or (3), you could coax MySQL into using the index by index hint sytax, but if you do, be sure run some tests to determine whether it actually improves performance to use the index as you hint it.

You may:

Or select the text, ctrl+K+L.

If you want an integer, try this code:

Having used a laptop with BitLocker enabled for almost 2 years now with more or less similar specs (although without the SSD unfortunately), I can say that it really isn't that bad, or even noticable. Although I have not used this particular machine without BitLocker enabled, it really does not feel sluggish at all when compared to my desktop machine (dual core, 16 GB, dual Raptor disks, no BitLocker). Building large projects might take a bit longer, but not enough to notice.

To back this up with more non-scientifical "proof": many of my co-workers used their machines intensively without BitLocker before I joined the company (it became mandatory to use it around the time I joined, even though I am pretty sure the two events are totally unrelated), and they have not experienced noticable performance degradation either.

For me personally, having an "always on" solution like BitLocker beats manual steps for encryption, hands-down. Bitlocker-to-go (new on Windows 7) for USB devices on the other hand is simply too annoying to work with, since you cannot easily exchange information with non-W7 machines. Therefore I use TrueCrypt for removable media.

You should be pointing it towards the Developer directory, not the Xcode application bundle. Run this:

sudo xcode-select --switch /Applications/Xcode.app/Contents/Developer

With recent versions of Xcode, you can go to Xcode ? Preferences… ? Locations and pick one of the options for Command Line Tools to set the location.

Here is a succinct variation that lets you specify any directory. The issue with using directories to find anything is that multiple variables can have the same value. So this code returns a list of possible variables.

def varname( var, dir=locals()):
  return [ key for key, val in dir.items() if id( val) == id( var)]

On windows in a corporate environment where certificates are distributed from a single source, I found this answer solved the issue: https://stackoverflow.com/a/48212753/761755

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

void print(int n)
{
    int q;

    printf("%d\n", n);
    q = 1000 / (1000 - n);
    print(n + 1);
}

int main(int argc, char *argv[])
{
    print(1);
    return EXIT_SUCCESS;
}

It will eventually stop :P

Even after going through many posts, it took several hours to figure out the problem. Here is the detailed approach written in simple language to run python via command line in windows.

1. Download executable file from python.org
Choose the latest version and download Windows-executable installer. Execute the downloaded file and let installation complete.

2. Ensure the file is downloaded in some administrator folder

1. Search file location of Python application.
2. Right click on the .exe file and navigate to its properties. Check if it is of the form, "C:\Users....". If NO, you are good to go and jump to step 3. Otherwise, clone the Python37 or whatever version you downloaded to one of these locations, "C:\", "C:\Program Files", "C:\Program Files (x86)".
   

3. Update the system PATH variable This is the most crucial step and there are two ways to do this:- (Follow the second one preferably)

1. MANUALLY
- Search for 'Edit the system Environment Variables' in the search bar.(WINDOWS 10)
- In the System Properties dialog, navigate to "Environment Variables".
- In the Environment Variables dialog look for "Path" under the System Variables window. (# Ensure to click on Path under bottom window named System Variables and not under user variables)
- Edit the Path Variable by adding location of Python37/ PythonXX folder. I added following line:-
" ;C:\Program Files (x86)\Python37;C:\Program Files (x86)\Python37\Scripts "
- Click Ok and close the dialogs.

2. SCRIPTED
- Open the command prompt and navigate to Python37/XX folder using cd command.
- Write the following statement:-
"python.exe Tools\Scripts\win_add2path.py"

You can now use python in the command prompt:)
1. Using Shell
Type python in cmd and use it.
2. Executing a .py file
Type python filename.py to execute it.

You can use the EXACT Function for exact string comparisons.

=IF(EXACT(A1, "ENG"), 1, 0)

You can always jump right to the root controller:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc = [storyboard instantiateInitialViewController];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];

If the list is empty I get an exception. This solution will take into account this issue:

int maxAge = context.Persons.Select(p => p.Age).DefaultIfEmpty(0).Max();

Other than calling gmdate you can also put this code before your rest of the code:

<?php
date_default_timezone_set("UTC");
?>

That will make rest of your date/time related calls to use GMT/UTC timezone.

I would ALWAYS go with both the alt and the title attributes. Many developers have been using this pattern now for over 20 years to deal with IE and other issues. So this is not new knowledge. Its just been rediscovered by new developers that didn't bother to learn from the past.

In addition, in HTML5 you should start using the new HTML5 picture element wrapped in figure with full WPA-ARIA attributes for greater accessibility, as well as support of assistive technologies, screen readers, and the like. Because this element is not supported in many older browsers...BUT degrades gracefully...I recommend the following HTML design pattern now for images in HTML:

<figure aria-labelledby="picturecaption2">
    <picture id="picture2">
        <source srcset="image.webp" type="image/webp" media="(min-width: 800px)" />
        <source srcset="image.gif" type="image/gif" />
        <img id="image2" style="height:auto;max-width: 100%;" src="image.jpg" width="255" height="200" alt="image:The World Wide Web" title="The World Wide Web" loading="lazy" no-referrer="no-referrer" onerror="this.onerror=null;" />
    </picture>
    <figcaption id="picturecaption2"><small>"My Cool Picture" [<a href="http://creativecommons.org/licenses/" target="_blank">A License</a>] , via <a href="https://commons.wikimedia.org/wiki/" target="_blank">Wikimedia Commons</a></small></figcaption>
</figure>

The code above has many extra "goodies" beside alt and title, including ARIA attributes, support for WebP, a media query supporting higher resolution imagery, and a nice fallback pattern supporting older image formats. It shows a fully decorated image example that uses new technologies while still supporting old ones with progressive design patterns.

REMEMBER...ALWAYS SUPPORT THE OLD BROWSERS!

Just to add Python 3 f-string solution

prob = 1.0/3.0
print(f"{prob:.0%}")

I had similar issue but I could not resolve it using static ip address or changing firewall settings. I found a useful utility which can be configured in a minute.

We can host our local web server on cloud for free. On exposing it on cloud we get a different URL which we can use instead of localhost and access the webserver from anywhere.

The utility is ngrok https://ngrok.com/download Steps:

1. Signup
2. Download
3. Extract the file and double click to run it, this will open a command prompt
4. Type "ngrok.exe http 80" without quotes to host for example XAMPP apache server which runs on port 80.
5. Copy the new url name generated on the cmd prompt for e.g. if it is like this "fafb42f.ngrok.io"

URL like : http://localhost/php/test.php Should be modified like this : http://fafb42f.ngrok.io/php/test.php

Now this URL can be accessed from phone.

Also another difference is taking into consideration a situation where there is a skew join and you have to coalesce on top of it. A repartition will solve the skew join in most cases, then you can do the coalesce.

Another situation is, suppose you have saved a medium/large volume of data in a data frame and you have to produce to Kafka in batches. A repartition helps to collectasList before producing to Kafka in certain cases. But, when the volume is really high, the repartition will likely cause serious performance impact. In that case, producing to Kafka directly from dataframe would help.

side notes: Coalesce does not avoid data movement as in full data movement between workers. It does reduce the number of shuffles happening though. I think that's what the book means.

If you're doing this to several fields, or doing it quite often, then perhaps a plugin is the answer.
Here's the beginnings of a jQuery plugin that formats the value of a field to two decimal places.
It is triggered by the onchange event of the field. You may want something different.

<script type="text/javascript">

    // mini jQuery plugin that formats to two decimal places
    (function($) {
        $.fn.currencyFormat = function() {
            this.each( function( i ) {
                $(this).change( function( e ){
                    if( isNaN( parseFloat( this.value ) ) ) return;
                    this.value = parseFloat(this.value).toFixed(2);
                });
            });
            return this; //for chaining
        }
    })( jQuery );

    // apply the currencyFormat behaviour to elements with 'currency' as their class
    $( function() {
        $('.currency').currencyFormat();
    });

</script>   
<input type="text" name="one" class="currency"><br>
<input type="text" name="two" class="currency">

Next variation on Peter Lawrey's answer without initialization of a new string every loop turn

String concatList(List<String> sList, String separator)
{
    Iterator<String> iter = sList.iterator();
    StringBuilder sb = new StringBuilder();

    while (iter.hasNext())
    {
        sb.append(iter.next()).append( iter.hasNext() ? separator : "");
    }
    return sb.toString();
}

I'm afraid that using map() method of an array may be expensive since entire array is to be iterated. Instead, I combine a new array that consists of three parts:

• head - items before the modified item
• the modified item
• tail - items after the modified item

Here the example I've used in my code (NgRx, yet the machanism is the same for other Redux implementations):

// toggle done property: true to false, or false to true

function (state, action) {
    const todos = state.todos;
    const todoIdx = todos.findIndex(t => t.id === action.id);

    const todoObj = todos[todoIdx];
    const newTodoObj = { ...todoObj, done: !todoObj.done };

    const head = todos.slice(0, todoIdx - 1);
    const tail = todos.slice(todoIdx + 1);
    const newTodos = [...head, newTodoObj, ...tail];
}

It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min and max attributes (in your case only the first attribute). For example:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>

I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step attribute:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>

Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .

BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.

For a list of browsers that support it, you can look at caniuse.com.

WebRupee is a web API for the Indian currency symbol. It provides a simple, cross browser method for using the Rrupee symbol on your webpage, blog or anywhere on the web.

Here is a method for printing the Indian currency symbol:

<html>
<head>
    <link rel="stylesheet" type="text/css" href="http://cdn.webrupee.com/font">
    <script src=http://cdn.webrupee.com/js type=”text/javascript”></script>
</head>
<body>
    Rupee Symbol: <span class="WebRupee">Rs.</span> 200

This means if somebody copies text from your site and pastes it somewhere else, he will see Rs and not some other or blank character.

You can now also use the new Rupee unicode symbol — U+20B9 INDIAN RUPEE SIGN. It can be used in this manner:

<span class="WebRupee">&#x20B9;</span> 500

Just include the following script and it will update all the "Rs" / "Rs." for you:

<script src="http://cdn.webrupee.com/js" type="text/javascript"></script>

#!/bin/bash

req=$(curl -s -X GET http://host:8080/some/resource -H "Accept: application/json") 2>&1
echo "${req}"

Why would you use it if you already knew the class and were going to cast it? Why not just do it the old fashioned way and make the class like you always make it? There's no advantage to this over the way it's done normally. Is there a way to take the text and operate on it thusly:

label1.txt = "Pizza" 
Magic(label1.txt) p = new Magic(lablel1.txt)(arg1, arg2, arg3);
p.method1();
p.method2();

If I already know its a Pizza there's no advantage to:

p = (Pizza)somefancyjunk("Pizza"); over
Pizza p = new Pizza();

but I see a huge advantage to the Magic method if it exists.

I would suggest using absolute positioning within the element.

I've created this to help you visualize it a bit.

#parent {_x000D_
    width:400px;_x000D_
    height:400px;_x000D_
    background-color:white;_x000D_
    border:2px solid blue;_x000D_
    position:relative;_x000D_
}_x000D_
#div1 {position:absolute;bottom:0;right:0;background:green;width:100px;height:100px;}_x000D_

#div3 {width:100px;height:100px;position:absolute;top:0;right:0;background:yellow;}_x000D_
#div4 {width:100px;height:100px;position:absolute;top:0;left:0;background:gray;}

<div id="parent">_x000D_

You could rollback the last migration by

rake db:rollback STEP=1

or rollback this specific migration by

rake db:migrate:down VERSION=<YYYYMMDDHHMMSS>

and edit the file, then run rake db:mirgate again.

This gives accurate results, when checking on a scrollable element (i.e. not window):

// `element` is a native JS HTMLElement
if ( element.scrollTop == (element.scrollHeight - element.offsetHeight) )
    // Element scrolled to bottom

offsetHeight should give the actual visible height of an element (including padding, margin, and scrollbars), and scrollHeight is the entire height of an element including invisible (overflowed) areas.

jQuery's .outerHeight() should give similar result to JS's .offsetHeight -- the documentation in MDN for offsetHeight is unclear about its cross-browser support. To cover more options, this is more complete:

var offsetHeight = ( container.offsetHeight ? container.offsetHeight : $(container).outerHeight() );
if  ( container.scrollTop == (container.scrollHeight - offsetHeight) ) {
   // scrolled to bottom
}

While other suggested solutions work, If you really want the solution to be made thread safe you should replace ArrayList with CopyOnWriteArrayList

    //List<String> s = new ArrayList<>(); //Will throw exception
    List<String> s = new CopyOnWriteArrayList<>();
    s.add("B");
    Iterator<String> it = s.iterator();
    s.add("A");

    //Below removes only "B" from List
    while (it.hasNext()) {
        s.remove(it.next());
    }
    System.out.println(s);

I force reload my component using *ngIf.

All the components inside my container goes back to the full lifecycle hooks .

In the template :

<ng-container *ngIf="_reload">
    components here 
</ng-container>

Then in the ts file :

public _reload = true;

private reload() {
    setTimeout(() => this._reload = false);
    setTimeout(() => this._reload = true);
}

You should use method listName.isEmpty()

I have a couple of suggestions:

1. First of all, you seem to be using API 4 as your target. AFAIK, it's good practice to always compile against the latest SDK and setup your android:minSdkVersion accordingly.

2. With that in mind, remember that android:required attribute was added in API 5:

The feature declaration can include an android:required=["true" | "false"] attribute (if you are compiling against API level 5 or higher), which lets you specify whether the application (...)

Thus, I'd suggest that you compile against SDK 15, set targetSdkVersion to 15 as well, and provide that functionality.

It also shows here, on the Play site, as incompatible with any device that I have that is (coincidence?) Gingerbread (Galaxy Ace and Galaxy Y here). But it shows as compatible with my Galaxy Tab 10.1 (Honeycomb), Nexus S and Galaxy Nexus (both on ICS).

That also left me wondering, and this is a very wild guess, but since android.hardware.faketouch is API11+, why don't you try removing it just to see if it works? Or perhaps that's all related anyway, since you're trying to use features (faketouch) and the required attribute that are not available in API 4. And in this case you should compile against the latest API.

I would try that first, and remove the faketouch requirement only as last resort (of course) --- since it works when developing, I'd say it's just a matter of the compiled app not recognizing the feature (due to the SDK requirements), thus leaving unexpected filtering issues on Play.

Sorry if this guess doesn't answer your question, but it's very difficult to diagnose those kind of problems and pinpoint the solution without actually testing. Or at least for me without all the proper knowledge of how Play really filters apps.

Good luck.

Usually 90 days are NOT 3 months literally, just a reference.

So, finally, you need to check if days are bigger than 15 to add +1 to month counter. or better, add another elif with half month counter.

From this other stackoverflow answer i've finally ended with that:

#/usr/bin/env python
# -*- coding: utf8 -*-

import datetime
from datetime import timedelta
from dateutil.relativedelta import relativedelta
import calendar

start_date = datetime.date.today()
end_date = start_date + timedelta(days=111)
start_month = calendar.month_abbr[int(start_date.strftime("%m"))]

print str(start_date) + " to " + str(end_date)

months = relativedelta(end_date, start_date).months
days = relativedelta(end_date, start_date).days

print months, "months", days, "days"

if days > 16:
    months += 1

print "around " + str(months) + " months", "(",

for i in range(0, months):
    print calendar.month_abbr[int(start_date.strftime("%m"))],
    start_date = start_date + relativedelta(months=1)

print ")"

Output:

2016-02-29 2016-06-14
3 months 16 days
around 4 months ( Feb Mar Apr May )

I've noticed that doesn't work if you add more than days left in current year, and that's is unexpected.

Also i got this error if i had the comment in tn top level of template among with the actual root element.

To avoid getting expections at run time , do something like this.

There are chances of having empty string sometimes,

string a = "abc,xyz,wer";
string b=string.Empty;

if(!string.IsNullOrEmpty(a ))
{
  b = a.Split(',')[0];
}

1) Plug in Phone through USB (w/ Developer Debugging options enabled)

2) Open Terminal and Navigate to your Android SDK (for Mac):

cd ~/Library/Android/sdk/platform-tools

3) Logcat from that directory (in your terminal) to generate a constant flow of logs (for Mac):

./adb logcat

4) Open your app that crashes to generate crash logs

5) Ctrl+C to stop terminal and look for the logs associated with the app that crashes. It may say something like the following:

AndroidRuntime: FATAL EXCEPTION: main

Set<E> alphaSet  = new HashSet<E>(<your List>);

or complete example

import java.util.ArrayList;
import java.util.HashSet;
import java.util.List;
import java.util.Set;

public class ListToSet
{
    public static void main(String[] args)
    {
        List<String> alphaList = new ArrayList<String>();
        alphaList.add("A");
        alphaList.add("B");
        alphaList.add("C");
        alphaList.add("A");
        alphaList.add("B");
        System.out.println("List values .....");
        for (String alpha : alphaList)
        {
            System.out.println(alpha);
        }
        Set<String> alphaSet = new HashSet<String>(alphaList);
        System.out.println("\nSet values .....");
        for (String alpha : alphaSet)
        {
            System.out.println(alpha);
        }
    }
}

I tried following code, which works for me.

            Process  mIpAddrProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
            int mExitValue = mIpAddrProcess.waitFor();
            System.out.println(" mExitValue "+mExitValue);
            if(mExitValue==0){
                return true;
            }else{
                return false;
            }
        }
        catch (InterruptedException ignore)
        {
            ignore.printStackTrace();
            System.out.println(" Exception:"+ignore);
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
            System.out.println(" Exception:"+e);
        }
        return false;
    }

One of the main purposes of integration testing with MockMvc is to verify that model objects are correclty populated with form data.

In order to do it you have to pass form data as they're passed from actual form (using .param()). If you use some automatic conversion from NewObject to from data, your test won't cover particular class of possible problems (modifications of NewObject incompatible with actual form).

Definitively, for any PHP project, you may want to use GuzzleHTTP for sending requests. Guzzle has very nice documentation you can check here. I just want to say that, you probably want to centralize the usage of the Client class of Guzzle in any component of your Laravel project (for example a trait) instead of being creating Client instances on several controllers and components of Laravel (as many articles and replies suggest).

I created a trait you can try to use, which allows you to send requests from any component of your Laravel project, just using it and calling to makeRequest.

namespace App\Traits;
use GuzzleHttp\Client;
trait ConsumesExternalServices
{
    /**
     * Send a request to any service
     * @return string
     */
    public function makeRequest($method, $requestUrl, $queryParams = [], $formParams = [], $headers = [], $hasFile = false)
    {
        $client = new Client([
            'base_uri' => $this->baseUri,
        ]);

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

class extends React.Component {
    onClickDiv = (column) => {
        // do stuff
    }
    render() {
        return <div onClick={() => this.onClickDiv('123')} />
    }
}

Another thing use "", there is a difference between "\r\n" and '\r\n'.

I strongly recommend using lowercase field|column names, it will make your life easier.

Let's assume you have a table called users with the following definition and records:

id|firstname|lastname|username             |password
1 |joe      |doe     |[email protected]   |1234
2 |jane     |doe     |[email protected]  |12345
3 |johnny   |doe     |[email protected]|123456

let's say you want to get all records from table users, then you do:

SELECT * FROM users;

Now let's assume you want to select all records from table users, but you're interested only in the fields id, firstname and lastname, thus ignoring username and password:

SELECT id, firstname, lastname FROM users;

Now we get at the point where you want to retrieve records based on condition(s), what you need to do is to add the WHERE clause, let's say we want to select from users only those that have username = [email protected] and password = 1234, what you do is:

SELECT * FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

But what if you need only the id of a record with username = [email protected] and password = 1234? then you do:

SELECT id FROM users
WHERE ( ( username = '[email protected]' ) AND ( password = '1234' ) );

Now to get to your question, as others before me answered you can use the IN clause:

SELECT * FROM users
WHERE ( id IN (1,2,..,n) );

or, if you wish to limit to a list of records between id 20 and id 40, then you can easily write:

SELECT * FROM users
WHERE ( ( id >= 20 ) AND ( id <= 40 ) );

I hope this gives a better understanding.

Jeff has a post about it, otherwise I found some useful documents on Apple's website, in Cocoa tutorials (this one for example).

Any Table ID

Use: INT(11).

MySQL indexes will be able to parse through an int list fastest.

Anything Security

Use: BINARY(x), or BLOB(x).

You can store security tokens, etc., as hex directly in BINARY(x) or BLOB(x). To retrieve from binary-type, use SELECT HEX(field)... or SELECT ... WHERE field = UNHEX("ABCD....").

Anything Date

Use: DATETIME, DATE, or TIME.

Always use DATETIME if you need to store both date and time (instead of a pair of fields), as a DATETIME indexing is more amenable to date-comparisons in MySQL.

Anything True-False

Use: BIT(1) (MySQL 8-only.) Otherwise, use BOOLEAN(1).

BOOLEAN is actually just an alias of TINYINT(1), which actually stores 0 to 255 (not exactly a true/false, is it?).

Anything You Want to call `SUM()`, `MAX()`, or similar functions on

Use: INT(11).

VARCHAR or other types of fields won't work with the SUM(), etc., functions.

Anything Over 1,000 Characters

Use: TEXT.

Max limit is 65,535.

Anything Over 65,535 Characters

Use: MEDIUMTEXT.

Max limit is 16,777,215.

Anything Over 16,777,215 Characters

Use: LONGTEXT.

Max limit is 4,294,967,295.

FirstName, LastName

Use : VARCHAR(255).

UTF-8 characters can take up three characters per visible character, and some cultures do not distinguish firstname and lastname. Additionally, cultures may have disagreements about which name is first and which name is last. You should name these fields Person.GivenName and Person.FamilyName.

Email Address

Use : VARCHAR(256).

The definition of an e-mail path is set in RFC821 in 1982. The maximum limit of an e-mail was set by RFC2821 in 2001, and these limits were kept unchanged by RFC5321 in 2008. (See the section: 4.5.3.1. Size Limits and Minimums.) RFC3696, published 2004, mistakenly cites the email address limit as 320 characters, but this was an "info-only" RFC that explicitly "defines no standards" according to its intro, so disregard it.

Phone

Use: VARCHAR(255).

You never know when the phone number will be in the form of "1800...", or "1-800", or "1-(800)", or if it will end with "ext. 42", or "ask for susan".

ZipCode

Use: VARCHAR(10).

You'll get data like 12345 or 12345-6789. Use validation to cleanse this input.

URL

Use: VARCHAR(2000).

Official standards support URL's much longer than this, but few modern browsers support URL's over 2,000 characters. See this SO answer: What is the maximum length of a URL in different browsers?

Price

Use: DECIMAL(11,2).

It goes up to 11.

On SuSE linux, you can use the following command to install 'texinfo':

sudo zypper install texinfo

On my system, it shows it is downloading about 1000 MiB, so make sure you have enough free space.

Here's my solution, loads from .json to allow changes without rebuilding

import { Injectable, Inject } from '@angular/core';
import { Http } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import { Location } from '@angular/common';

@Injectable()
export class ConfigService {

    private config: any;

    constructor(private location: Location, private http: Http) {
    }

    async apiUrl(): Promise<string> {
        let conf = await this.getConfig();
        return Promise.resolve(conf.apiUrl);
    }

    private async getConfig(): Promise<any> {
        if (!this.config) {
            this.config = (await this.http.get(this.location.prepareExternalUrl('/assets/config.json')).toPromise()).json();
        }
        return Promise.resolve(this.config);
    }
}

and config.json

{
    "apiUrl": "http://localhost:3000/api"
}

Maybe you should try LocallyDB it's easy-to-use and lightweight in addition to the with advanced selecting system similar to javascript conditional expression...

https://github.com/btwael/locallydb

A little late to the party, but I think many are struggling with this...

I've been searching for this as well. And to get your method/action running async without waiting or blocking the thread, you'll need to queue it via the SynchronizationContext, so I came up with this solution:

I've made a helper-class for it.

public static class ASyncHelper
{

    public static void RunAsync(Func<Task> func)
    {
        var context = SynchronizationContext.Current;

        // you don't want to run it on a threadpool. So if it is null, 
        // you're not on a UI thread.
        if (context == null)
            throw new NotSupportedException(
                "The current thread doesn't have a SynchronizationContext");

        // post an Action as async and await the function in it.
        context.Post(new SendOrPostCallback(async state => await func()), null);
    }

    public static void RunAsync<T>(Func<T, Task> func, T argument)
    {
        var context = SynchronizationContext.Current;

        // you don't want to run it on a threadpool. So if it is null, 
        // you're not on a UI thread.
        if (context == null)
            throw new NotSupportedException(
                "The current thread doesn't have a SynchronizationContext");

        // post an Action as async and await the function in it.
        context.Post(new SendOrPostCallback(async state => await func((T)state)), argument);
    }
}

Usage/Example:

public partial class Form1 : Form
{

    private async Task Initialize()
    {
        // replace code here...
        await Task.Delay(1000);
    }

    private async Task Run(string myString)
    {

        // replace code here...
        await Task.Delay(1000);
    }

    public Form1()
    {
        InitializeComponent();

        // you don't have to await nothing.. (the thread must be running)
        ASyncHelper.RunAsync(Initialize);
        ASyncHelper.RunAsync(Run, "test");

        // In your case
        ASyncHelper.RunAsync(getWritings);
    }
}

This works for Windows.Forms and WPF

You can see in this List of useful HTTP headers.

X-XSS-Protection: This header enables the Cross-site scripting (XSS) filter built into most recent web browsers. It's usually enabled by default anyway, so the role of this header is to re-enable the filter for this particular website if it was disabled by the user. This header is supported in IE 8+, and in Chrome (not sure which versions). The anti-XSS filter was added in Chrome 4. Its unknown if that version honored this header.

You can make the single letter optional by adding a ? after it as:

([A-Z]{1}?)

The quantifier {1} is redundant so you can drop it.

You can use something like this

if ($("#formID input:checkbox:checked").length > 0)
{
    // any one is checked
}
else
{
   // none is checked
}

First of all, you don't quite get what's reduce's previous value is.

In you pseudo code you have return previous.value + current.value, therefore the previous value will be a number on the next call, not an object.

Second, reduce is an Array method, not an Object's one, and you can't rely on the order when you're iterating the properties of an object (see: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Statements/for...in, this is applied to Object.keys too); so I'm not sure if applying reduce over an object makes sense.

However, if the order is not important, you can have:

Object.keys(obj).reduce(function(sum, key) {
    return sum + obj[key].value;
}, 0);

Or you can just map the object's value:

Object.keys(obj).map(function(key) { return this[key].value }, obj).reduce(function (previous, current) {
    return previous + current;
});

P.S. in ES6 with the fat arrow function's syntax (already in Firefox Nightly), you could shrink a bit:

Object.keys(obj).map(key => obj[key].value).reduce((previous, current) => previous + current);

private function upload_files($path, $title, $files)
{
    $config = array(
        'upload_path'   => $path,
        'allowed_types' => 'jpg|gif|png',
        'overwrite'     => 1,
    );

    $this->load->library('upload', $config);

    $images = array();

    foreach ($files['name'] as $key => $image) {
        $_FILES['images[]']['name']= $files['name'][$key];
        $_FILES['images[]']['type']= $files['type'][$key];
        $_FILES['images[]']['tmp_name']= $files['tmp_name'][$key];
        $_FILES['images[]']['error']= $files['error'][$key];
        $_FILES['images[]']['size']= $files['size'][$key];

        $fileName = $title .'_'. $image;

        $images[] = $fileName;

        $config['file_name'] = $fileName;

        $this->upload->initialize($config);

        if ($this->upload->do_upload('images[]')) {
            $this->upload->data();
        } else {
            return false;
        }
    }
    return true;
}

As olt already pointed out, Image.paste doesn't work properly, when source and destination both contain alpha.

Consider the following scenario:

Two test images, both contain alpha:

layer1 = Image.open("layer1.png")
layer2 = Image.open("layer2.png")

Compositing image using Image.paste like so:

final1 = Image.new("RGBA", layer1.size)
final1.paste(layer1, (0,0), layer1)
final1.paste(layer2, (0,0), layer2)

produces the following image (the alpha part of the overlayed red pixels is completely taken from the 2nd layer. The pixels are not blended correctly):

Compositing image using Image.alpha_composite like so:

final2 = Image.new("RGBA", layer1.size)
final2 = Image.alpha_composite(final2, layer1)
final2 = Image.alpha_composite(final2, layer2)

produces the following (correct) image:

Push SVG element to last, so that its z-index will be in top. In SVG, there s no property called z-index. try below javascript to bring the element to top.

var Target = document.getElementById(event.currentTarget.id);
var svg = document.getElementById("SVGEditor");
svg.insertBefore(Target, svg.lastChild.nextSibling);

Target: Is an element for which we need to bring it to top svg: Is the container of elements

Use: LOGGER.log(Level.INFO, "Got an exception.", e);
or LOGGER.info("Got an exception. " + e.getMessage());

This happened to me because strangely GIT thought that the local branch was different from the remote branch. This was visible in the branch graph: it displayed two different branches: remotes/origin/branch_name and branch_name.

The solution was simply to remove the local repo and re-clone it from remote. This way GIT would understand that remotes/origin/branch_name>and branch_name are indeed the same, and I could issue the git merge branch_name.

rm <my_repo>
git clone <my_repo>
cd <my_repo>
git checkout <branch_name>
git pull
git checkout master
git merge <branch_name>

From C++ Primer:

The istringstream type reads a string, ostringstream writes a string, and stringstream reads and writes the string.

I come across some cases where it is both convenient and concise to use stringstream.

case 1

It is from one of the solutions for this leetcode problem. It demonstrates a very suitable case where the use of stringstream is efficient and concise.

Suppose a and b are complex numbers expressed in string format, we want to get the result of multiplication of a and b also in string format. The code is as follows:

string a = "1+2i", b = "1+3i";
istringstream sa(a), sb(b);
ostringstream out;

int ra, ia, rb, ib;
char buff;
// only read integer values to get the real and imaginary part of 
// of the original complex number
sa >> ra >> buff >> ia >> buff;
sb >> rb >> buff >> ib >> buff;

out << ra*rb-ia*ib << '+' << ra*ib+ia*rb << 'i';

// final result in string format
string result = out.str() 

case 2

It is also from a leetcode problem that requires you to simplify the given path string, one of the solutions using stringstream is the most elegant that I have seen:

string simplifyPath(string path) {
    string res, tmp;
    vector<string> stk;
    stringstream ss(path);
    while(getline(ss,tmp,'/')) {
        if (tmp == "" or tmp == ".") continue;
        if (tmp == ".." and !stk.empty()) stk.pop_back();
        else if (tmp != "..") stk.push_back(tmp);
    }
    for(auto str : stk) res += "/"+str;
    return res.empty() ? "/" : res; 
 }

Without the use of stringstream, it would be difficult to write such concise code.

I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.

import java.util.*;
import java.lang.*;

public class foo
{

   public static void main(String[] args)
   { 
      double[] alpha = new double[50];
      int count = 0;

      for (int i=0; i<50; i++)
      {
          // System.out.print("variable i = " + i + "\n");
          if (i < 25)
          {
                alpha[i] = i*i;
          }
          else {
                alpha[i] = 3*i;
          }

          if (count < 10)
          {
            System.out.print(alpha[i]+ " "); 
          }  
          else {
            System.out.print("\n"); 
            System.out.print(alpha[i]+ " "); 
            count = 0;
          }

          count++;
      }

      System.out.print("\n"); 

    }
}

You can solve this temporarily by using the Firefox add-on, CORS Everywhere. Just open Firefox, press Ctrl+Shift+A , search the add-on and add it!

Using ES6.

let arr = [22,1,4,55,7,8,9,3,2,4];

let {0 : first ,[arr.length - 1] : last} = arr;
console.log(first, last);

or

let {0 : first ,length : l, [l - 1] : last} = [22,1,4,55,7,8,9,3,2,4];
console.log(first, last);

On Webpack 2 I tried all 12 devtool options. The following options link to the original file in the console and preserve line numbers. See the note below re: lines only.

lines only

Source Maps are simplified to a single mapping per line. This usually means a single mapping per statement (assuming you author is this way). This prevents you from debugging execution on statement level and from settings breakpoints on columns of a line. Combining with minimizing is not possible as minimizers usually only emit a single line.

REVISITING THIS

On a large project I find ... eval-source-map rebuild time is ~3.5s ... inline-source-map rebuild time is ~7s

While it is quite late to answer now, there is a simple way one could find if Nth bit is set or not, simply using POWER and MODULUS mathematical operators.

Let us say we want to know if 'temp' has Nth bit set or not. The following boolean expression will give true if bit is set, 0 otherwise.

• ( temp MODULUS 2^N+1 >= 2^N )

Consider the following example:

• int temp = 0x5E; // in binary 0b1011110 // BIT 0 is LSB

If I want to know if 3rd bit is set or not, I get

• (94 MODULUS 16) = 14 > 2^3

So expression returns true, indicating 3rd bit is set.

if you have neccessary .net framework installed. Ex ; .Net 4.0 or .Net 3.5, then you can just copy Gacutil.exe from any of the machine and to the new machine.

1) Open CMD as adminstrator in new server.
2) Traverse to the folder where you copied the Gacutil.exe. For eg - C:\program files.(in my case).
3) Type the below in the cmd prompt and install.

C:\Program Files\gacutil.exe /I dllname
