Thanks for the direction from the above two answerers. James Thompson's suggestion worked best for Windows users.

1. Go to where your R program is installed. This is referred to as R_Home in the literature. Once you find it, go to the /etc subdirectory.

   C:\R\R-2.10.1\etc
   

2. Select the file in this folder named Rprofile.site. I open it with VIM. You will find this is a bare-bones file with less than 20 lines of code. I inserted the following inside the code:

   # my custom library path
   .libPaths("C:/R/library")
   

   (The comment added to keep track of what I did to the file.)

3. In R, typing the .libPaths() function yields the first target at C:/R/Library

NOTE: there is likely more than one way to achieve this, but other methods I tried didn't work for some reason.

The most simple what I've found to get the XPath for a particular Element is to install FireBug extension for Firefox go to the site/webpage press F12 to bring up firebug; right select and right click the element on the page that you want to query and select "Inspect Element" Firebug will select the element in its IDE then right click the Element in Firebug and choose "Copy XPath" this function will give you the exact XPath Query you need to get the element you want using HTML Agility Library.

Even better than Ran's suggestion of using GetProcAddress, simply make the call to LoadLibrary before any calls to the DllImport functions (with only a filename without a path) and they'll use the loaded module automatically.

I've used this method to choose at runtime whether to load a 32-bit or 64-bit native DLL without having to modify a bunch of P/Invoke-d functions. Stick the loading code in a static constructor for the type that has the imported functions and it'll all work fine.

One subtle point I think I've discovered about the top voted answers is that even though they correctly change the selected value, they do not update the element that the user sees (only when they click the widget will they see a check next to the updated element).

Chaining a .change() call to the end will also update the UI widget as well.

$("#target").val($("#target option:first").val()).change();

(Note that I noticed this while using jQuery Mobile and a box on Chrome desktop, so this may not be the case everywhere).

I just set JAVA_HOME to the output of that command, which should give you the Java path specified in your Java preferences. Here's a snippet from my .bashrc file, which sets this variable:

export JAVA_HOME=$(/usr/libexec/java_home)

I haven't experienced any problems with that technique.

Occasionally I do have to change the value of JAVA_HOME to an earlier version of Java. For example, one program I'm maintaining requires 32-bit Java 5 on OS X, so when using that program, I set JAVA_HOME by running:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.5)

For those of you who don't have java_home in your path add it like this.

sudo ln -s /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java_home /usr/libexec/java_home

Cells cannot be changed from within a VBA function used as a worksheet formula. Except via this workaround...

Put this function into a new module:

Function SetRGB(x As Range, R As Byte, G As Byte, B As Byte)
  On Error Resume Next
  x.Interior.Color = RGB(R, G, B)
  x.Font.Color = IIf(0.299 * R + 0.587 * G + 0.114 * B < 128, vbWhite, vbBlack)
End Function

Then use this formula in your sheet, for example in cell D2:

=HYPERLINK(SetRGB(D2;A2;B2;C2);"HOVER!")

Once you hover the mouse over the cell (try it!), the background color updates to the RGB taken from cells A2 to C2. The font color is a contrasting white or black.

Simple install with NVM...

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
. ~/.nvm/nvm.sh
nvm install node

To install a certain version (such as 12.16.3) of Node change the last line to

nvm install 12.16.3

For more information about how to use NVM visit the docs: https://github.com/nvm-sh/nvm

the difference is not between <span> and <div> specifically, but between inline and block elements. <span> defaults to being display:inline; whereas <div> defaults to being display:block;. But these can be overridden in CSS.

The difference in the way text-align:center works between the two is down to the width.

A block element defaults to being the width of its container. It can have its width set using CSS, but either way it is a fixed width.

An inline element takes its width from the size of its content text.

text-align:center tells the text to position itself centrally in the element. But in an inline element, this is clearly not going to have any effect because the element is the same width as the text; aligning it one way or the other is meaningless.

In a block element, because the element's width is independent of the content, the content can be positioned within the element using the text-align style.

Finally, a solution for you:

There is an additional value for the display property which provides a half-way house between block and inline. Conveniently enough, it's called inline-block. If you specify a <span> to be display:inline-block; in the CSS, it will continue to work as an inline element but will take on some of the properties of a block as well, such as the ability to specify a width. Once you specify a width for it, you will be able to center the text within that width using text-align:center;

Hope that helps.

You can't declare an array using a variable so Byte byteData[len]; won't work. If you want to copy the data from a pointer, you also need to memcpy (which will go through the data pointed to by the pointer and copy each byte up to a specified length).

Try:

NSData *data = [NSData dataWithContentsOfFile:filePath];
NSUInteger len = [data length];
Byte *byteData = (Byte*)malloc(len);
memcpy(byteData, [data bytes], len);

This code will dynamically allocate the array to the correct size (you must free(byteData) when you're done) and copy the bytes into it.

You could also use getBytes:length: as indicated by others if you want to use a fixed length array. This avoids malloc/free but is less extensible and more prone to buffer overflow issues so I rarely ever use it.

Here's how i conditionally applied gray text style on a disabled button

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  styleUrls: [ './app.component.css' ],
  template: `
  <button 
    (click)='buttonClick1()' 
    [disabled] = "btnDisabled"
    [ngStyle]="{'color': (btnDisabled)? 'gray': 'black'}">
    {{btnText}}
  </button>`
})
export class AppComponent  {
  name = 'Angular';
  btnText = 'Click me';
  btnDisabled = false;
  buttonClick1() {
    this.btnDisabled = true;
    this.btnText = 'you clicked me';
    setTimeout(() => {
      this.btnText = 'click me again';
      this.btnDisabled = false
      }, 5000);
  }
}

Here's a working example:
https://stackblitz.com/edit/example-conditional-disable-button?file=src%2Fapp%2Fapp.component.html

I am using XPathSelectElements extension method which works in the same way to XmlDocument.SelectNodes method:

using System;
using System.Xml.Linq;
using System.Xml.XPath; // for XPathSelectElements

namespace testconsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            XDocument xdoc = XDocument.Parse(
                @"<root>
                    <child>
                        <name>john</name>
                    </child>
                    <child>
                        <name>fred</name>
                    </child>
                    <child>
                        <name>mark</name>
                    </child>
                 </root>");

            foreach (var childElem in xdoc.XPathSelectElements("//child"))
            {
                string childName = childElem.Element("name").Value;
                Console.WriteLine(childName);
            }
        }
    }
}

If you are trying to populate a table from a SQL dump, make sure that the table listed in the "INSERT INTO" statements of the dump is the same one you are trying to populate. Opening "MyTable" and importing with a SQL dump will throw exactly that kind of error if the dump is trying to put entries into "MyOtherTable", which may already have entries.

A small variation but nothing new infact. It's really missing a feature...

select info->>'name' from rabbits 
where '"carrots"' = ANY (ARRAY(
    select * from json_array_elements(info->'food'))::text[]);

You must set the Gravity like this:

(textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);

Have you tried, after calling DataBind on your DropDownList, to do something like ddl.SelectedIndex = 0 ?

There is a generic solution:

Lets say you have a controller named Admin where you put content for authorized users.

Then, you can override the Initialize or OnAuthorization methods of Admin controller and write redirect to login page logic on session timeout in these methods as described:

protected override void OnAuthorization(System.Web.Mvc.AuthorizationContext filterContext)
    {
        //lets say you set session value to a positive integer
        AdminLoginType = Convert.ToInt32(filterContext.HttpContext.Session["AdminLoginType"]);
        if (AdminLoginType == 0)
        {
            filterContext.HttpContext.Response.Redirect("~/login");
        }

        base.OnAuthorization(filterContext);
    }

This works fine for me:

while True:
   answer = input('Do you want to continue?:')
   if answer.lower().startswith("y"):
      print("ok, carry on then")
   elif answer.lower().startswith("n"):
      print("sayonara, Robocop")
      exit()

edit: use input in python 3.2 instead of raw_input

For those who don't want to use a third-party library... An issue with Elias Zamaria's answer is that it converts to float, which can run into problems. For example:

>>> json.dumps({'x': Decimal('0.0000001')}, cls=DecimalEncoder)
'{"x": 1e-07}'
>>> json.dumps({'x': Decimal('100000000000.01734')}, cls=DecimalEncoder)
'{"x": 100000000000.01733}'

The JSONEncoder.encode() method lets you return the literal json content, unlike JSONEncoder.default(), which has you return a json compatible type (like float) that then gets encoded in the normal way. The problem with encode() is that it (normally) only works at the top level. But it's still usable, with a little extra work (python 3.x):

import json
from collections.abc import Mapping, Iterable
from decimal import Decimal

class DecimalEncoder(json.JSONEncoder):
    def encode(self, obj):
        if isinstance(obj, Mapping):
            return '{' + ', '.join(f'{self.encode(k)}: {self.encode(v)}' for (k, v) in obj.items()) + '}'
        if isinstance(obj, Iterable) and (not isinstance(obj, str)):
            return '[' + ', '.join(map(self.encode, obj)) + ']'
        if isinstance(obj, Decimal):
            return f'{obj.normalize():f}'  # using normalize() gets rid of trailing 0s, using ':f' prevents scientific notation
        return super().encode(obj)

Which gives you:

>>> json.dumps({'x': Decimal('0.0000001')}, cls=DecimalEncoder)
'{"x": 0.0000001}'
>>> json.dumps({'x': Decimal('100000000000.01734')}, cls=DecimalEncoder)
'{"x": 100000000000.01734}'

I think the available libraries, tools, examples, and communities completely trumps the paradigm these days. For example, ML (or whatever) might be the ultimate all-purpose programming language but if you can't get any good libraries for what you are doing you're screwed.

For example, if you're making a video game, there are more good code examples and SDKs in C++, so you're probably better off with that. For a small web application, there are some great Python, PHP, and Ruby frameworks that'll get you off and running very quickly. Java is a great choice for larger projects because of the compile-time checking and enterprise libraries and platforms.

It used to be the case that the standard libraries for different languages were pretty small and easily replicated - C, C++, Assembler, ML, LISP, etc.. came with the basics, but tended to chicken out when it came to standardizing on things like network communications, encryption, graphics, data file formats (including XML), even basic data structures like balanced trees and hashtables were left out!

Modern languages like Python, PHP, Ruby, and Java now come with a far more decent standard library and have many good third party libraries you can easily use, thanks in great part to their adoption of namespaces to keep libraries from colliding with one another, and garbage collection to standardize the memory management schemes of the libraries.

The key of this problem is to detect the load-more event, start an async request for data and then update the list. Also an adapter with loading indicator and other decorators is needed. In fact, the problem is very complicated in some corner cases. Just a OnScrollListener implementation is not enough, because sometimes the items do not fill the screen.

I have written a personal package which support endless list for RecyclerView, and also provide a async loader implementation AutoPagerFragment which makes it very easy to get data from a multi-page source. It can load any page you want into a RecyclerView on a custom event, not only the next page.

Here is the address: https://github.com/SphiaTower/AutoPagerRecyclerManager

It means that there is only one instance of "clock" in Hello, not one per each separate instance of the "Hello" class, or more-so, it means that there will be one commonly shared "clock" reference among all instances of the "Hello" class.

So if you were to do a "new Hello" anywhere in your code: A- in the first scenario (before the change, without using "static"), it would make a new clock every time a "new Hello" is called, but B- in the second scenario (after the change, using "static"), every "new Hello" instance would still share and use the initial and same "clock" reference first created.

Unless you needed "clock" somewhere outside of main, this would work just as well:

package hello;
public class Hello
{
    public static void main(String args[])
    {
      Clock clock=new Clock();
      clock.sayTime();    
    }
}

You can use display: table-cell property as in the following code:

div {
     height: 100%;
     display: table-cell; 
     vertical-align: middle;
    }

Try this:

string myText = "a Simple string";

string asTitleCase =
    System.Threading.Thread.CurrentThread.CurrentCulture.TextInfo.
    ToTitleCase(myText.ToLower());

As has already been pointed out, using TextInfo.ToTitleCase might not give you the exact results you want. If you need more control over the output, you could do something like this:

IEnumerable<char> CharsToTitleCase(string s)
{
    bool newWord = true;
    foreach(char c in s)
    {
        if(newWord) { yield return Char.ToUpper(c); newWord = false; }
        else yield return Char.ToLower(c);
        if(c==' ') newWord = true;
    }
}

And then use it like so:

var asTitleCase = new string( CharsToTitleCase(myText).ToArray() );

using Array Reduce function will get/set based on path provided.

i tested it with a.b.c and a.b.2.c {a:{b:[0,1,{c:7}]}} and its works for both getting key or mutating object to set value

cheerz

    function setOrGet(obj, path=[], newValue){
      const l = typeof path === 'string' ? path.split('.') : path;
      return l.reduce((carry,item, idx)=>{
       const leaf = carry[item];
       
       // is this last item in path ? cool lets set/get value
       if( l.length-idx===1)  { 
         // mutate object if newValue is set;
         carry[item] = newValue===undefined ? leaf : newValue;
         // return value if its a get/object if it was a set
         return newValue===undefined ? leaf : obj ;
       }
    
       carry[item] = leaf || {}; // mutate if key not an object;
       return carry[item]; // return object ref: to continue reduction;
      }, obj)
    }
    
   
    console.log(
     setOrGet({a: {b:1}},'a.b') === 1 ||
    'Test Case: Direct read failed'
    )
    
    console.log(
     setOrGet({a: {b:1}},'a.c',22).a.c===22 ||
    'Test Case: Direct set failed'
    )
    
    console.log(
     setOrGet({a: {b:[1,2]}},'a.b.1',22).a.b[1]===22 ||
    'Test Case: Direct set on array failed'
    )
    
    console.log(
     setOrGet({a: {b:{c: {e:1} }}},'a.b.c.e',22).a.b.c. e===22 ||
    'Test Case: deep get failed'
    )
    
    // failed !. Thats your homework :) 
    console.log(
     setOrGet({a: {b:{c: {e:[1,2,3,4,5]} }}},'a.b.c.e.3 ',22)
    )
    
    
    
    

my personal recommendation.

do not use such a thing unless there is no other way!

i saw many examples people use it for translations for example from json; so you see function like locale('app.homepage.welcome') . this is just bad. if you already have data in an object/json; and you know path.. then just use it directly example locale().app.homepage.welcome by changing you function to return object you get typesafe, with autocomplete, less prone to typo's ..

There is a useful Web API method called URL

const url = new URL('http://www.somedomain.com/account/search?filter=a#top');_x000D_
console.log(url.pathname.split('/'));_x000D_
const params = new URLSearchParams(url.search)_x000D_
console.log(params.get("filter"))

In my case an unexpected error notice in the source code stopped the facebook crawler from parsing the (correctly set) og-meta tags.

I was using the HTTP_ACCEPT_LANGUAGE header, which worked fine for regular browser requests but not for the crawler, as it obviously won't use/set it.

Therefore, it was crucial for me to use the facebook's debugger feature See exactly what our scraper sees for your URL, as the error notice only could only be seen there (but not through the regular 'view source code'-browser feature).

Creating DLL File

1. Open Visual Studio then select File -> New -> Project

2. Select Visual C# -> Class library

3. Compile Project Or Build the solution, to create Dll File

4. Go to the class library folder (Debug Folder)

You must use OpenSSL and keytool.

OpenSSL for CER & PVK file > P12

openssl pkcs12 -export -name servercert -in selfsignedcert.crt -inkey serverprivatekey.key -out myp12keystore.p12

Keytool for p12 > JKS

keytool -importkeystore -destkeystore mykeystore.jks -srckeystore myp12keystore.p12 -srcstoretype pkcs12 -alias servercert

final means that the value cannot be changed after initialization, that's what makes it a constant. static means that instead of having space allocated for the field in each object, only one instance is created for the class.

So, static final means only one instance of the variable no matter how many objects are created and the value of that variable can never change.

I had the same problem. I changed the localhost parameter in the mysqli object to '127.0.0.1' instead of writing 'localhost'. It worked; I’m not sure how or why.

$db_connection = new mysqli("127.0.0.1","root","","db_name");

Hope it helps.

I had same issue as I had missed adding composeEnhancers. Once this is setup then you can take a look into action creators. You get this error when this is not setup as well.

const composeEnhancers = window.__REDUX_DEVTOOLS_EXTENSION_COMPOSE__ || compose;

const store = createStore(
  rootReducer,
  composeEnhancers(applyMiddleware(thunk))
);

The same way you do it in other db system, you can use the name of the db for identifying double named tables. unique tablenames can used directly.

select * from ttt.table_name;

or if table name in all attached databases is unique

select * from my_unique_table_name;

But I think the of of sqlite-shell is only for manual lookup or manual data manipulation and therefor this way is more inconsequential

normally you would use sqlite-command-line in a script

For Sql server you can try this one.

SELECT ISNULL([NAME],'SUM'),Count([NAME]) AS COUNT
FROM TABLENAME
GROUP BY [NAME] WITH CUBE

Based on my experience, even with python 3.3+, an empty __init__.py is still needed sometimes. One situation is when you want to refer a subfolder as a package. For example, when I ran python -m test.foo, it didn't work until I created an empty __init__.py under the test folder. And I'm talking about 3.6.6 version here which is pretty recent.

Apart from that, even for reasons of compatibility with existing source code or project guidelines, its nice to have an empty __init__.py in your package folder.

You just need to copy/cut and paste the images into drawable folder using windows/mac file explorer

To refresh the workspace follow the steps mentioned in this question Eclipse: How do i refresh an entire workspace? F5 doesn't do it

DAO = Data Access Object.
DTO = Data Transfer Object.

In my case, I was using an invalid string prefix.

Wrong:

path = f"D:\Folder\file.txt"

Right:

path = r"D:\Folder\file.txt"

Also worth noting, for people who find this in their searches, is this...

<div ng-repeat="button in buttons" class="bb-button" ng-click="goTo(button.path)">
  <div class="bb-button-label">{{ button.label }}</div>
  <div class="bb-button-description">{{ button.description }}</div>
</div>

Note the value of ng-click. The parameter passed to goTo() is a string from a property of the binding object (the button), but it is not wrapped in quotes. Looks like AngularJS handles that for us. I got hung up on that for a few minutes.

Other answers have shown you how to use JUnit to set up test classes. JUnit is not the only Java test framework. Concentrating on the technical details of using a framework however detracts from the most important concepts that should be guiding your actions, so I will talk about those.

• Testing (of all kinds of all kinds of things) compares the actual behaviour of something (The System Under Test, SUT) with its expected behaviour.

• Automated testing can be done using a computer program. Because that comparison is being done by an inflexible and unintelligent computer program, the expected behaviour must be precisely and unambiguously known.

• What a program or part of a program (a class or method) is expected to do is its specification. Testing software therefore requires that you have a specification for the SUT. This might be an explicit description, or an implicit specification in your head of what is expected.

• Automated unit testing therefore requires a precise and unambiguous specification of the class or method you are testing.

• But you needed that specification when you set out to write that code. So part of what testing is about actually begins before you write even one line of the SUT. The testing technique of Test Driven Development (TDD) takes that idea to an extreme, and has you create the unit testing code before you write the code to be tested.

• Unit testing frameworks test your SUT using assertions. An assertion is a logical expression (an expression with a boolean result type; a predicate) that must be true if the SUT is behaving correctly. The specification must therefore be expressed (or re-expressed) as assertions.

• A useful technique for expressing a specification as assertions is programming by contract. These specifications are in terms of postconditions. A postcondition is an assertion about the publicly visible state of the SUT after return from a method or a constructor. Some methods have postconditions that are invariants, which are predicates that are true before and after execution of the method. A class can also be said to have invariants, which are postconditions of every constructor and method of the class, and hence should always be true. Postconditions (And invariants) are expressed only in terms of publicity visible state: public and protected fields, the values returned by returned by public and protected methods (such as getters), and the publicly visible state of objects passed (by reference) to methods.

Many beginners post questions here asking how they can test some code, presenting the code but without stating the specification for that code. As this discussion shows, it is impossible for anyone to give a good answer to such a question, because at best potential answereres must guess the specification, and might do so incorrectly. The asker of the question evidently does not understand the importance of a specification, and is thus a novice who needs to understand the fundamentals I've described here before trying to write some test code.

Here's an example that puts the Now() value in column A.

Sub move()
    Dim i As Integer
    Dim sh1 As Worksheet
    Dim sh2 As Worksheet
    Dim nextRow As Long
    Dim copyRange As Range
    Dim destRange As Range

    Application.ScreenUpdating = False

        Set sh1 = ActiveWorkbook.Worksheets("Sheet1")
        Set sh2 = ActiveWorkbook.Worksheets("Sheet2")
        Set copyRange = sh1.Range("A1:A5")

        i = Application.WorksheetFunction.CountA(sh2.Range("B:B")) + 4

        Set destRange = sh2.Range("B" & i)

        destRange.Resize(1, copyRange.Rows.Count).Value = Application.Transpose(copyRange.Value)
        destRange.Offset(0, -1).Value = Format(Now(), "MMM-DD-YYYY")

        copyRange.Clear

There are better ways of getting the last row in column B than using a While loop, plenty of examples around here. Some are better than others but depend on what you're doing and what your worksheet structure looks like. I used one here which assumes that column B is ALL empty except the rows/records you're moving. If that's not the case, or if B1:B3 have some values in them, you'd need to modify or use another method. Or you could just use your loop, but I'd search for alternatives :)

I followed below steps for resolution for this issue in Windows 10:

1. First make sure you have installed Angular CLI . You can use below to install same.

npm install -g @angular/cli@latest

2. Make sure that AppData is visible and navigate to path below.

C:\Users\rkota\AppData\Roaming\npm

Same path can be found by running below too:

npm config get prefix

3. Add the above path i.e. " C:\Users\rkota\AppData\Roaming\npm" in Environment variable PATH and make sure it got added by running path in command prompt.
4. Close command prompt and now try to run below:

ng --version

you will be able to see CLI version.

I want to select the distinct values from one column 'GrondOfLucht' but they should be sorted in the order as given in the column 'sortering'. I cannot get the distinct values of just one column using

Select distinct GrondOfLucht,sortering
from CorWijzeVanAanleg
order by sortering

It will also give the column 'sortering' and because 'GrondOfLucht' AND 'sortering' is not unique, the result will be ALL rows.

use the GROUP to select the records of 'GrondOfLucht' in the order given by 'sortering

SELECT        GrondOfLucht
FROM            dbo.CorWijzeVanAanleg
GROUP BY GrondOfLucht, sortering
ORDER BY MIN(sortering)

In case you are indeed using the SSH URL, but still are asked for username and password when git pushing:

git remote set-url origin [email protected]:<Username>/<Project>.git

You should try troubleshooting with:

ssh -vT [email protected]

Below is a piece of sample output:

...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_dsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ecdsa
debug1: Trying private key: /c/Users/Yuci/.ssh/id_ed25519
debug1: No more authentication methods to try.
Permission denied (publickey).

I actually have already added the public key to GitHub before, and I also have the private key locally. However, my private key is of a different name called /c/Users/Yuci/.ssh/github_rsa.

According to the sample output, Git is trying /c/Users/Yuci/.ssh/id_rsa, which I don't have. Therefore, I could simply copy github_rsa to id_rsa in the same directory.

cp /c/Users/Yuci/.ssh/github_rsa /c/Users/Yuci/.ssh/id_rsa

Now when I run ssh -vT [email protected] again, I have:

...
debug1: Trying private key: /c/Users/Yuci/.ssh/id_rsa
debug1: Authentication succeeded (publickey).
...
Hi <my username>! You've successfully authenticated, but GitHub does not provide shell access.
...

And now I can push to GitHub without being asked for username and password :-)

I usually use a little modified version of ngLink's answer.

public class MyControl : Control
{
    private int suspendCounter = 0;

    private void SuspendDrawing()
    {
        if(suspendCounter == 0) 
            SendMessage(this.Handle, WM_SETREDRAW, false, 0);
        suspendCounter++;
    }

    private void ResumeDrawing()
    {
        suspendCounter--; 
        if(suspendCounter == 0) 
        {
            SendMessage(this.Handle, WM_SETREDRAW, true, 0);
            this.Refresh();
        }
    }
}

This allows suspend/resume calls to be nested. You must make sure to match each SuspendDrawing with a ResumeDrawing. Hence, it wouldn't probably be a good idea to make them public.

Although the accepted solution is correct for iPhones, it will incorrectly declare both isiPhone and isiPad to be true for users visiting your site on their iPad from the Facebook app.

The conventional wisdom is that iOS devices have a user agent for Safari and a user agent for the UIWebView. This assumption is incorrect as iOS apps can and do customize their user agent. The main offender here is Facebook.

Compare these user agent strings from iOS devices:

# iOS Safari
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9B176 Safari/7534.48.3
iPhone: Mozilla/5.0 (iPhone; CPU iPhone OS 5_0 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Version/5.1 Mobile/9A334 Safari/7534.48.3

# UIWebView
iPad: Mozilla/5.0 (iPad; CPU OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/98176
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_1 like Mac OS X; en-us) AppleWebKit/532.9 (KHTML, like Gecko) Mobile/8B117

# Facebook UIWebView
iPad: Mozilla/5.0 (iPad; U; CPU iPhone OS 5_1_1 like Mac OS X; en_US) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1.1;FBBV/4110.0;FBDV/iPad2,1;FBMD/iPad;FBSN/iPhone OS;FBSV/5.1.1;FBSS/1; FBCR/;FBID/tablet;FBLC/en_US;FBSF/1.0]
iPhone: Mozilla/5.0 (iPhone; U; CPU iPhone OS 5_1_1 like Mac OS X; ru_RU) AppleWebKit (KHTML, like Gecko) Mobile [FBAN/FBForIPhone;FBAV/4.1;FBBV/4100.0;FBDV/iPhone3,1;FBMD/iPhone;FBSN/iPhone OS;FBSV/5.1.1;FBSS/2; tablet;FBLC/en_US]

Note that on the iPad, the Facebook UIWebView's user agent string includes 'iPhone'.

The old way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);

If you were to go with this approach for detecting iPhone and iPad, you would end up with IS_IPHONE and IS_IPAD both being true if a user comes from Facebook on an iPad. That could create some odd behavior!

The correct way to identify iPhone / iPad in JavaScript:

IS_IPAD = navigator.userAgent.match(/iPad/i) != null;
IS_IPHONE = (navigator.userAgent.match(/iPhone/i) != null) || (navigator.userAgent.match(/iPod/i) != null);
if (IS_IPAD) {
  IS_IPHONE = false;
}

We declare IS_IPHONE to be false on iPads to cover for the bizarre Facebook UIWebView iPad user agent. This is one example of how user agent sniffing is unreliable. The more iOS apps that customize their user agent, the more issues user agent sniffing will have. If you can avoid user agent sniffing (hint: CSS Media Queries), DO IT.

I like ranges for this:

def first_half(list)
  list[0...(list.length / 2)]
end

def last_half(list)
  list[(list.length / 2)..list.length]
end

However, be very careful about whether the endpoint is included in your range. This becomes critical on an odd-length list where you need to choose where you're going to break the middle. Otherwise you'll end up double-counting the middle element.

The above example will consistently put the middle element in the last half.

Restart Eclipse and check log cat will be displayed.

The answer provided by @Matthias Herlitzius is mostly correct. Just for further clarity.

The servlet-api jar is best left up to the server to manage see here for detail

With that said, the dependency to add may vary according to your server/container. For example in Wildfly the dependency would be

<dependency>
    <groupId>org.jboss.spec.javax.servlet</groupId>
    <artifactId>jboss-servlet-api_3.1_spec</artifactId>
    <scope>provided</scope>
</dependency>

So becareful to check how your container has provided the servlet implementation.

To exclude the first line (header) from sorting, I split it out into two buffers.

df | awk 'BEGIN{header=""; $body=""} { if(NR==1){header=$0}else{body=body"\n"$0}} END{print header; print body|"sort -nk3"}'

"a"[0]

or

?a

Both would return their ASCII equivalent.

The answer is in the documentation:

Real partial mocks (Since 1.8.0)

Finally, after many internal debates & discussions on the mailing list, partial mock support was added to Mockito. Previously we considered partial mocks as code smells. However, we found a legitimate use case for partial mocks.

Before release 1.8 spy() was not producing real partial mocks and it was confusing for some users. Read more about spying: here or in javadoc for spy(Object) method.

callRealMethod() was introduced after spy(), but spy() was left there of course, to ensure backward compatibility.

Otherwise, you're right: all the methods of a spy are real unless stubbed. All the methods of a mock are stubbed unless callRealMethod() is called. In general, I would prefer using callRealMethod(), because it doesn't force me to use the doXxx().when() idiom instead of the traditional when().thenXxx()

I solved my problem like this...

Environment: Cordova 8.1.1, Android Studio 3.2, cordova-android 7.0.0

1. Set gradle PATH into .profile file.

export PATH="/Applications/Android Studio.app/Contents/gradle/gradle-4.6/bin":$PATH

2. Export the setting.

source ~/.profle

3. Now build cordova project.

PS: If [email protected] causes build error, downgrade your platform version to 6.3.0.

In Ruby and other languages that support POSIX character classes in bracket expressions, you can do simply:

/\A[[:alpha:]]+\z/i

That will match alpha-chars in all Unicode alphabet languages. Easy peasy.

More info: http://en.wikipedia.org/wiki/Regular_expression#Character_classes http://ruby-doc.org/core-2.0/Regexp.html

The Adjusted R-squared is close to, but different from, the value of R2. Instead of being based on the explained sum of squares SSR and the total sum of squares SSY, it is based on the overall variance (a quantity we do not typically calculate), s2T = SSY/(n - 1) and the error variance MSE (from the ANOVA table) and is worked out like this: adjusted R-squared = (s2T - MSE) / s2T.

This approach provides a better basis for judging the improvement in a fit due to adding an explanatory variable, but it does not have the simple summarizing interpretation that R2 has.

If I haven't made a mistake, you should verify the values of adjusted R-squared and R-squared as follows:

s2T <- sum(anova(v.lm)[[2]]) / sum(anova(v.lm)[[1]])
MSE <- anova(v.lm)[[3]][2]
adj.R2 <- (s2T - MSE) / s2T

On the other side, R2 is: SSR/SSY, where SSR = SSY - SSE

attach(v)
SSE <- deviance(v.lm) # or SSE <- sum((epm - predict(v.lm,list(n_days)))^2)
SSY <- deviance(lm(epm ~ 1)) # or SSY <- sum((epm-mean(epm))^2)
SSR <- (SSY - SSE) # or SSR <- sum((predict(v.lm,list(n_days)) - mean(epm))^2)
R2 <- SSR / SSY 

 //To show xml tags in table columns you will have to encode the tags first

function htmlEncode(value) {
    //create a in-memory div, set it's inner text(which jQuery automatically encodes)
    //then grab the encoded contents back out.  The div never exists on the page.
    return $('<div/>').text(value).html();
}

html = htmlEncode(html)

You can comma-separate shadows:

box-shadow: inset 0 2px 0px #dcffa6, 0 2px 5px #000;

If the input happens to be in a bootstrap modal dialog, the answer is different. Copying from How to Set focus to first text input in a bootstrap modal after shown this is what is required:

$('#myModal').on('shown.bs.modal', function () {
  $('#textareaID').focus();
})  

For completeness, in addition to the other answers, if the thread is interrupted before it blocks on Object.wait(..) or Thread.sleep(..) etc., this is equivalent to it being interrupted immediately upon blocking on that method, as the following example shows.

public class InterruptTest {
    public static void main(String[] args) {

        Thread.currentThread().interrupt();

        printInterrupted(1);

        Object o = new Object();
        try {
            synchronized (o) {
                printInterrupted(2);
                System.out.printf("A Time %d\n", System.currentTimeMillis());
                o.wait(100);
                System.out.printf("B Time %d\n", System.currentTimeMillis());
            }
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("C Time %d\n", System.currentTimeMillis());

        printInterrupted(3);

        Thread.currentThread().interrupt();

        printInterrupted(4);

        try {
            System.out.printf("D Time %d\n", System.currentTimeMillis());
            Thread.sleep(100);
            System.out.printf("E Time %d\n", System.currentTimeMillis());
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("F Time %d\n", System.currentTimeMillis());

        printInterrupted(5);

        try {
            System.out.printf("G Time %d\n", System.currentTimeMillis());
            Thread.sleep(100);
            System.out.printf("H Time %d\n", System.currentTimeMillis());
        } catch (InterruptedException ie) {
            System.out.printf("WAS interrupted\n");
        }
        System.out.printf("I Time %d\n", System.currentTimeMillis());

    }
    static void printInterrupted(int n) {
        System.out.printf("(%d) Am I interrupted? %s\n", n,
                Thread.currentThread().isInterrupted() ? "Yes" : "No");
    }
}

Output:

$ javac InterruptTest.java 

$ java -classpath "." InterruptTest
(1) Am I interrupted? Yes
(2) Am I interrupted? Yes
A Time 1399207408543
WAS interrupted
C Time 1399207408543
(3) Am I interrupted? No
(4) Am I interrupted? Yes
D Time 1399207408544
WAS interrupted
F Time 1399207408544
(5) Am I interrupted? No
G Time 1399207408545
H Time 1399207408668
I Time 1399207408669

Implication: if you loop like the following, and the interrupt occurs at the exact moment when control has left Thread.sleep(..) and is going around the loop, the exception is still going to occur. So it is perfectly safe to rely on the InterruptedException being reliably thrown after the thread has been interrupted:

while (true) {
    try {
        Thread.sleep(10);
    } catch (InterruptedException ie) {
        break;
    }
}

I am not 100% certain, but I think this does what you want using prop.table. See mostly the last 3 lines. The rest of the code is just creating fake data.

set.seed(1234)

total_bill <- rnorm(50, 25, 3)
tip <- 0.15 * total_bill + rnorm(50, 0, 1)
sex <- rbinom(50, 1, 0.5)
smoker <- rbinom(50, 1, 0.3)
day <- ceiling(runif(50, 0,7))
time <- ceiling(runif(50, 0,3))
size <- 1 + rpois(50, 2)
my.data <- as.data.frame(cbind(total_bill, tip, sex, smoker, day, time, size))
my.data

my.table <- table(my.data$smoker)

my.prop <- prop.table(my.table)

cbind(my.table, my.prop)

I tried the codes from bootstrap's document as follows:

<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>tab demo</title>
  <link rel="stylesheet" href="bootstrap.css">

<div class="span9">
    <div class="tabbable"> <!-- Only required for left/right tabs -->
      <ul class="nav nav-tabs">
        <li class="active"><a href="#tab1" data-toggle="tab">Section 1</a></li>
        <li><a href="#tab2" data-toggle="tab">Section 2</a></li>
      </ul>
      <div class="tab-content">
        <div class="tab-pane active" id="tab1">
          <p>I'm in Section 1.</p>
        </div>
        <div class="tab-pane" id="tab2">
          <p>Howdy, I'm in Section 2.</p>
        </div>
      </div>
    </div>
</div> 
<script src="jquery.min.js"></script>
<script src="bootstrap.js"></script>
</body>
</html>

and it works. But when I switch these two <script src...>'s postion, it do not work. So please remember to load your jquery script before bootstrap.js.

It should be

yadayada.val.split(/\n/)

you're passing in a literal string to the split command, not a regex.

I made a POC for an Angular application using multiple modules and router-outlets to nest sub apps in a single page app. You can get the source code at: https://github.com/AhmedBahet/ng-sub-apps

For those, who use 'copy' command in Build Events (Pre-build event command line or/and Post-build event command line) from Project -> Properties: target folder should exist

The border is given the whole html element. If you want half bottom border, you can wrap it with some other identifiable block like span.

HTML code:

<div> <span>content here </span></div>

CSS as below:

 div{
    width:200px;
    height:50px;   
    }
 span{
        width:100px;
        border-bottom:1px solid magenta;   
    } 

When is it ok to use READ UNCOMMITTED?

Rule of thumb

Good: Big aggregate reports showing constantly changing totals.

Risky: Nearly everything else.

The good news is that the majority of read-only reports fall in that Good category.

More detail...

Ok to use it:

• Nearly all user-facing aggregate reports for current, non-static data e.g. Year to date sales. It risks a margin of error (maybe < 0.1%) which is much lower than other uncertainty factors such as inputting error or just the randomness of when exactly data gets recorded minute to minute.

That covers probably the majority of what an Business Intelligence department would do in, say, SSRS. The exception of course, is anything with $ signs in front of it. Many people account for money with much more zeal than applied to the related core metrics required to service the customer and generate that money. (I blame accountants).

When risky

• Any report that goes down to the detail level. If that detail is required it usually implies that every row will be relevant to a decision. In fact, if you can't pull a small subset without blocking it might be for the good reason that it's being currently edited.

• Historical data. It rarely makes a practical difference but whereas users understand constantly changing data can't be perfect, they don't feel the same about static data. Dirty reads won't hurt here but double reads can occasionally be. Seeing as you shouldn't have blocks on static data anyway, why risk it?

• Nearly anything that feeds an application which also has write capabilities.

When even the OK scenario is not OK.

• Are any applications or update processes making use of big single transactions? Ones which remove then re-insert a lot of records you're reporting on? In that case you really can't use NOLOCK on those tables for anything.

This forum suggests also:

SELECT CATALOG_NAME AS DataBaseName
FROM INFORMATION_SCHEMA.SCHEMATA

As @PavelAnossov answered, the canonical answer, use the word_tokenize function in nltk:

from nltk import word_tokenize
sent = "This is my text, this is a nice way to input text."
word_tokenize(sent)

If your sentence is truly simple enough:

Using the string.punctuation set, remove punctuation then split using the whitespace delimiter:

import string
x = "This is my text, this is a nice way to input text."
y = "".join([i for i in x if not in string.punctuation]).split(" ")
print y

Using jQuery

I would create a button and an invisible input like so:

<button id="button">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

and add some jQuery to trigger it:

$('#button').on('click', function() {
    $('#file-input').trigger('click');
});

Using Vanilla JS

Same idea, without jQuery (credits to @Pascale):

<button onclick="document.getElementById('file-input').click();">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

Responsive, transparent background, variable height and style of divider, variable position of text, adjustable distance between divider and text. Can also be applied multiple times with different selectors for multiple divider styles in same project.
SCSS below.

Markup (HTML):

<div class="divider" text-position="right">Divider</div>

CSS:

.divider {
  display: flex;
  align-items: center;
  padding: 0 1rem;
}

.divider:before,
.divider:after {
  content: '';
  flex: 0 1 100%;
  border-bottom: 5px dotted #ccc;
  margin: 0 1rem;
}

.divider:before {
  margin-left: 0;
}

.divider:after {
  margin-right: 0;
}

.divider[text-position="right"]:after,
.divider[text-position="left"]:before {
  content: none;
}

Without text-position it defaults to center.

Demo:

.divider {_x000D_
  display: flex;_x000D_
  align-items: center;_x000D_
  padding: 0 1rem;_x000D_
}_x000D_
_x000D_
.divider:before,_x000D_
.divider:after {_x000D_
  content: '';_x000D_
  flex: 0 1 100%;_x000D_
  border-bottom: 5px dotted #ccc;_x000D_
  margin: 0 1rem;_x000D_
}_x000D_
_x000D_
.divider:before {_x000D_
  margin-left: 0;_x000D_
}_x000D_
_x000D_
.divider:after {_x000D_
  margin-right: 0;_x000D_
}_x000D_
_x000D_
.divider[text-position="right"]:after,_x000D_
.divider[text-position="left"]:before {_x000D_
  content: none;_x000D_
}

<span class="divider" text-position="left">Divider</span>_x000D_
<h2 class="divider">Divider</h2>_x000D_
<div class="divider" text-position="right">Divider</div>

And SCSS, to modify it quickly:

$divider-selector    : ".divider";
$divider-border-color: rgba(0,0,0,.21);
$divider-padding     : 1rem;
$divider-border-width: 1px;
$divider-border-style: solid;
$divider-max-width   : 100%;

#{$divider-selector} {
    display: flex;
    align-items: center;
    padding: 0 $divider-padding;
    max-width: $divider-max-width;
    margin-left: auto;
    margin-right: auto;

    &:before,
    &:after {
        content: '';
        flex: 0 1 100%;
        border-bottom: $divider-border-width $divider-border-style $divider-border-color;
        margin: 0 $divider-padding;
        transform: translateY(#{$divider-border-width} / 2)
    }

    &:before {
        margin-left: 0;
    }

    &:after {
        margin-right: 0;
    }

    &[text-position="right"]:after,
    &[text-position="left"]:before {
        content: none;
    }
}

(UPDATED with examples for Bootstrap v4, v3 and v3)

Examples of forms with validation classes for the past few major versions of Bootstrap.

Bootstrap v4

See the live version on codepen

<div class="container">
  <form>
    <div class="form-group row">
      <label for="inputEmail" class="col-sm-2 col-form-label text-success">Email</label>
      <div class="col-sm-7">
        <input type="email" class="form-control is-valid" id="inputEmail" placeholder="Email">
      </div>
    </div>

    <div class="form-group row">
      <label for="inputPassword" class="col-sm-2 col-form-label text-danger">Password</label>
      <div class="col-sm-7">
        <input type="password" class="form-control is-invalid" id="inputPassword" placeholder="Password">
      </div>
      <div class="col-sm-3">
        <small id="passwordHelp" class="text-danger">
          Must be 8-20 characters long.
        </small>      
      </div>
    </div>
  </form>
</div>

Bootstrap v3

See the live version on codepen

<form role="form">
  <div class="form-group has-warning">
    <label class="control-label" for="inputWarning">Input with warning</label>
    <input type="text" class="form-control" id="inputWarning">
    <span class="help-block">Something may have gone wrong</span>
  </div>
  <div class="form-group has-error">
    <label class="control-label" for="inputError">Input with error</label>
    <input type="text" class="form-control" id="inputError">
    <span class="help-block">Please correct the error</span>
  </div>
  <div class="form-group has-info">
    <label class="control-label" for="inputError">Input with info</label>
    <input type="text" class="form-control" id="inputError">
    <span class="help-block">Username is taken</span>
  </div>
  <div class="form-group has-success">
    <label class="control-label" for="inputSuccess">Input with success</label>
    <input type="text" class="form-control" id="inputSuccess" />
    <span class="help-block">Woohoo!</span>
  </div>
</form>

Bootstrap v2

See the live version on jsfiddle

The .error, .success, .warning and .info classes are appended to the .control-group. This is standard Bootstrap markup and styling in v2. Just follow that and you're in good shape. Of course you can go beyond with your own styles to add a popup or "inline flash" if you prefer, but if you follow Bootstrap convention and hang those validation classes on the .control-group it will stay consistent and easy to manage (at least since you'll continue to have the benefit of Bootstrap docs and examples)

  <form class="form-horizontal">
    <div class="control-group warning">
      <label class="control-label" for="inputWarning">Input with warning</label>
      <div class="controls">
        <input type="text" id="inputWarning">
        <span class="help-inline">Something may have gone wrong</span>
      </div>
    </div>
    <div class="control-group error">
      <label class="control-label" for="inputError">Input with error</label>
      <div class="controls">
        <input type="text" id="inputError">
        <span class="help-inline">Please correct the error</span>
      </div>
    </div>
    <div class="control-group info">
      <label class="control-label" for="inputInfo">Input with info</label>
      <div class="controls">
        <input type="text" id="inputInfo">
        <span class="help-inline">Username is taken</span>
      </div>
    </div>
    <div class="control-group success">
      <label class="control-label" for="inputSuccess">Input with success</label>
      <div class="controls">
        <input type="text" id="inputSuccess">
        <span class="help-inline">Woohoo!</span>
      </div>
    </div>
  </form>

You can do same thing using single query

SELECT sum(if(DATE(dDate)=DATE(CURRENT_TIMESTAMP),earning,null)) astodays,
       sum(if(YEARWEEK(dDate)=YEARWEEK(CURRENT_DATE),earning,null)) as weeks, 
       IF((MONTH(dDate) = MONTH(CURRENT_TIMESTAMP()) AND YEAR(dDate) = YEAR(CURRENT_TIMESTAMP())),sum(earning),0) AS months,
       IF(YEAR(dDate) = YEAR(CURRENT_TIMESTAMP()),sum(earning),0) AS years, 
       sum(fAdminFinalEarning) as total_earning FROM `earning`

Hope this works.

(function(undefined){
    var charsToReplace = {
        '&': '&',
        '<': '&lt;',
        '>': '&gt;'
    };

    var replaceReg = new RegExp("[" + Object.keys(charsToReplace).join("") + "]", "g");
    var replaceFn = function(tag){ return charsToReplace[tag] || tag; };

    var replaceRegF = function(replaceMap) {
        return (new RegExp("[" + Object.keys(charsToReplace).concat(Object.keys(replaceMap)).join("") + "]", "gi"));
    };
    var replaceFnF = function(replaceMap) {
        return function(tag){ return replaceMap[tag] || charsToReplace[tag] || tag; };
    };

    String.prototype.htmlEscape = function(replaceMap) {
        if (replaceMap === undefined) return this.replace(replaceReg, replaceFn);
        return this.replace(replaceRegF(replaceMap), replaceFnF(replaceMap));
    };
})();

No global variables, some memory optimization. Usage:

"some<tag>and&symbol©".htmlEscape({'©': '&copy;'})

result is:

"some<tag>and&symbol©"

I'm using UAParser https://github.com/faisalman/ua-parser-js

I had this problem today. I'm using systemjs to load the dependencies.

I was loading the Rxjs like this:

...
    paths: {
        "rxjs/*": "node_modules/rxjs/bundles/Rx.umd.min.js"
    },
...

Instead of use paths use this:

var map = {
...
'rxjs':                       'node_modules/rxjs',
...
}

var packages = {
...
'rxjs': { main: 'bundles/Rx.umd.min.js', defaultExtension: 'js' }
...
}

This little change in the way systemjs loads the library fixed my problem.

There kind of is. I created Sudo for Windows back in 2007? 08? Here's the security paper I wrote about it - https://www.sans.org/reading-room/whitepapers/bestprac/sudo-windows-sudowin-1726. Pretty sure http://sudowin.sf.net still works too.

In my case it is required to calculate the complete month from the start date to the day prior to this day in the next month or from start to end of month.

Ex: from 1/1/2018 to 31/1/2018 is a complete month
Ex2: from 5/1/2018 to 4/2/2018 is a complete month

so based on this here is my solution:

public static DateTime GetMonthEnd(DateTime StartDate, int MonthsCount = 1)
{
    return StartDate.AddMonths(MonthsCount).AddDays(-1);
}
public static Tuple<int, int> CalcPeriod(DateTime StartDate, DateTime EndDate)
{
    int MonthsCount = 0;
    Tuple<int, int> Period;
    while (true)
    {
        if (GetMonthEnd(StartDate) > EndDate)
            break;
        else
        {
            MonthsCount += 1;
            StartDate = StartDate.AddMonths(1);
        }
    }
    int RemainingDays = (EndDate - StartDate).Days + 1;
    Period = new Tuple<int, int>(MonthsCount, RemainingDays);
    return Period;
}

Usage:

Tuple<int, int> Period = CalcPeriod(FromDate, ToDate);

Note: in my case it was required to calculate the remaining days after the complete months so if it's not your case you could ignore the days result or even you could change the method return from tuple to integer.

You can use the window.innerHeight

The declarative and simpler solution would be :

yourMutableMap.replaceAll((key, val) -> return_value_of_bi_your_function); Nb. be aware your modifying your map state. So this may not be what you want.

Cheers to : http://www.deadcoderising.com/2017-02-14-java-8-declarative-ways-of-modifying-a-map-using-compute-merge-and-replace/

If you don't see a certain package, you can access to a full list of ports (also unnoficials, the packages you see on the web) launching the setup.exe with -k argument with value http://cygwinports.org/ports.gpg (example: C:\cygwin\setup\setup-x86.exe -K http://cygwinports.org/ports.gpg).

Doing so, you can choose a lot of extra packages, also extra versions of cURL (compat one). I do that to get Apache, cUrl, php5, php5-curl and some others :)

I don't know if apt-cyg can get those extra packages.

Setting height to 101% is my solution to the problem. You pages will no longer 'flick' when switching between ones that exceed the viewport height and ones that do not.

request.input("name", sql.Decimal, 155.33)              // decimal(18, 0)
request.input("name", sql.Decimal(10), 155.33)          // decimal(10, 0)
request.input("name", sql.Decimal(10, 2), 155.33)       // decimal(10, 2)

In C++ std::string the length() and size() method gives you the number of bytes, and not necessarily the number of characters !. Same with the c-Style sizeof() function!

For most of the printable 7bit-ASCII Characters this is the same value, but for characters that are not 7bit-ASCII it's definitely not. See the following example to give you real results (64bit linux).

There is no simple c/c++ function that can really count the number of characters. By the way, all of this stuff is implementation dependent and may be different on other environments (compiler, win 16/32, linux, embedded, ...)

See following example:

#include <string>
#include <iostream>
#include <stdio.h>
#include <string.h>
using namespace std;

int main()
{
/* c-Style char Array */
const char * Test1 = "1234";
const char * Test2 = "ÄÖÜ€";
const char * Test3 = "aß?";

/* c++ string object */
string sTest1 = "1234";
string sTest2 = "ÄÖÜ€";
string sTest3 = "aß?";

printf("\r\nC Style Resluts:\r\n");
printf("Test1: %s, strlen(): %d\r\n",Test1, (int) strlen(Test1));
printf("Test2: %s, strlen(): %d\r\n",Test2, (int) strlen(Test2));
printf("Test3: %s, strlen(): %d\r\n",Test3, (int) strlen(Test3));

printf("\r\nC++ Style Resluts:\r\n");
cout << "Test1: " << sTest1 << ", Test1.size():  " <<sTest1.size() <<"  sTest1.length(): " << sTest1.length() << endl;
cout << "Test1: " << sTest2 << ", Test2.size():  " <<sTest2.size() <<"  sTest1.length(): " << sTest2.length() << endl;
cout << "Test1: " << sTest3 << ", Test3.size(): " <<sTest3.size() << "  sTest1.length(): " << sTest3.length() << endl;
return 0;
}

The output of the example is this:

C Style Results:
Test1: ABCD, strlen(): 4    
Test2: ÄÖÜ€, strlen(): 9
Test3: aß?, strlen(): 10

C++ Style Results:
Test1: ABCD, sTest1.size():  4  sTest1.length(): 4
Test2: ÄÖÜ€, sTest2.size():  9  sTest2.length(): 9
Test3: aß?, sTest3.size(): 10  sTest3.length(): 10

Just want to sum up, there might be 4 ways.

• If you don't have much space, add a click event for text or button, then show UIPickerView:

or open a new table view control with a check mark:

• If there is more space, add a table view directly to your main view:

• The final solution is using UISegmentedControl:

Hope this helps.

From the official Swift programming guide:

Global variables are variables that are defined outside of any function, method, closure, or type context. Global constants and variables are always computed lazily.

You can define it in any file and can access it in current module anywhere. So you can define it somewhere in the file outside of any scope. There is no need for static and all global variables are computed lazily.

 var yourVariable = "someString"

You can access this from anywhere in the current module.

However you should avoid this as Global variables are not good for application state and mainly reason of bugs.

As shown in this answer, in Swift you can encapsulate them in struct and can access anywhere. You can define static variables or constant in Swift also. Encapsulate in struct

struct MyVariables {
    static var yourVariable = "someString"
}

You can use this variable in any class or anywhere

let string = MyVariables.yourVariable
println("Global variable:\(string)")

//Changing value of it
MyVariables.yourVariable = "anotherString"

select ROUND(CASE 

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))!='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

WHEN  CONVERT( float, REPLACE( isnull( value1,''),',',''))!='' AND CONVERT( float, REPLACE( isnull( value2,''),',',''))='' then  CONVERT( float, REPLACE( isnull( value3,''),',',''))

else CONVERT( float, REPLACE(isnull( value1,''),',','')) end,0)  from Tablename where    ID="123" 

It might not work correctly when using a program that is not attached to the console, because that app might still be running while you think you have the exit code. A solution to do it in C++ looks like below:

#include "stdafx.h"
#include "windows.h"
#include "stdio.h"
#include "tchar.h"
#include "stdio.h"
#include "shellapi.h"

int _tmain( int argc, TCHAR *argv[] )
{

    CString cmdline(GetCommandLineW());
    cmdline.TrimLeft('\"');
    CString self(argv[0]);
    self.Trim('\"');
    CString args = cmdline.Mid(self.GetLength()+1);
    args.TrimLeft(_T("\" "));
    printf("Arguments passed: '%ws'\n",args);
    STARTUPINFO si;
    PROCESS_INFORMATION pi;

    ZeroMemory( &si, sizeof(si) );
    si.cb = sizeof(si);
    ZeroMemory( &pi, sizeof(pi) );

    if( argc < 2 )
    {
        printf("Usage: %s arg1,arg2....\n", argv[0]);
        return -1;
    }

    CString strCmd(args);
    // Start the child process. 
    if( !CreateProcess( NULL,   // No module name (use command line)
        (LPTSTR)(strCmd.GetString()),        // Command line
        NULL,           // Process handle not inheritable
        NULL,           // Thread handle not inheritable
        FALSE,          // Set handle inheritance to FALSE
        0,              // No creation flags
        NULL,           // Use parent's environment block
        NULL,           // Use parent's starting directory 
        &si,            // Pointer to STARTUPINFO structure
        &pi )           // Pointer to PROCESS_INFORMATION structure
    ) 
    {
        printf( "CreateProcess failed (%d)\n", GetLastError() );
        return GetLastError();
    }
    else
        printf( "Waiting for \"%ws\" to exit.....\n", strCmd );

    // Wait until child process exits.
    WaitForSingleObject( pi.hProcess, INFINITE );
    int result = -1;
    if(!GetExitCodeProcess(pi.hProcess,(LPDWORD)&result))
    { 
        printf("GetExitCodeProcess() failed (%d)\n", GetLastError() );
    }
    else
        printf("The exit code for '%ws' is %d\n",(LPTSTR)(strCmd.GetString()), result );
    // Close process and thread handles. 
    CloseHandle( pi.hProcess );
    CloseHandle( pi.hThread );
    return result;
}

There isn't a built-in "PowerShell" way of running a SQL query. If you have the SQL Server tools installed, you'll get an Invoke-SqlCmd cmdlet.

Because PowerShell is built on .NET, you can use the ADO.NET API to run your queries.

Use the frames collection.

From the link:

var frames = window.frames; // or // var frames = window.parent.frames;
for (var i = 0; i < frames.length; i++) { 
  // do something with each subframe as frames[i]
  frames[i].document.body.style.background = "red";
}

If the iframe has a name you may also do the following:

window.frames['ponies'].number_of_ponies = 7;

You can only do this if the two pages are served from the same domain.

This snippet of code will recursively convert that data to a single type (array or object) without the nested foreach loops. Hope it helps someone!

Once an Object is in array format you can use array_merge and convert back to Object if you need to.

abstract class Util {
    public static function object_to_array($d) {
        if (is_object($d))
            $d = get_object_vars($d);

        return is_array($d) ? array_map(__METHOD__, $d) : $d;
    }

    public static function array_to_object($d) {
        return is_array($d) ? (object) array_map(__METHOD__, $d) : $d;
    }
}

Procedural way

function object_to_array($d) {
    if (is_object($d))
        $d = get_object_vars($d);

    return is_array($d) ? array_map(__FUNCTION__, $d) : $d;
}

function array_to_object($d) {
    return is_array($d) ? (object) array_map(__FUNCTION__, $d) : $d;
}

You can use DISTINCT like that

mysql_query("SELECT DISTINCT(ticket_id), column1, column2, column3 
FROM temp_tickets 
ORDER BY ticket_id");

You need to create a separate interface for your custom methods:

public interface AccountRepository 
    extends JpaRepository<Account, Long>, AccountRepositoryCustom { ... }

public interface AccountRepositoryCustom {
    public void customMethod();
}

and provide an implementation class for that interface:

public class AccountRepositoryImpl implements AccountRepositoryCustom {

    @Autowired
    @Lazy
    AccountRepository accountRepository;  /* Optional - if you need it */

    public void customMethod() { ... }
}

Thats where asp.net puts dynamically compiled assemblies.

If your goal is to simply display some static files you can use the Connect package. I have had some success (I'm still pretty new to NodeJS myself), using it and the twitter bootstrap API in combination.

at the command line

:\> cd <path you wish your server to reside>
:\> npm install connect

Then in a file (I named) Server.js

var connect = require('connect'),
   http = require('http');
connect()
   .use(connect.static('<pathyouwishtoserve>'))
   .use(connect.directory('<pathyouwishtoserve>'))
   .listen(8080);

Finally

:\>node Server.js

Caveats:

If you don't want to display the directory contents, exclude the .use(connect.directory line.

So I created a folder called "server" placed index.html in the folder and the bootstrap API in the same folder. Then when you access the computers IP:8080 it's automagically going to use the index.html file.

If you want to use port 80 (so just going to http://, and you don't have to type in :8080 or some other port). you'll need to start node with sudo, I'm not sure of the security implications but if you're just using it for an internal network, I don't personally think it's a big deal. Exposing to the outside world is another story.

Update 1/28/2014:

I haven't had to do the following on my latest versions of things, so try it out like above first, if it doesn't work (and you read the errors complaining it can't find nodejs), go ahead and possibly try the below.

End Update

Additionally when running in ubuntu I ran into a problem using nodejs as the name (with NPM), if you're having this problem, I recommend using an alias or something to "rename" nodejs to node.

Commands I used (for better or worse):

Create a new file called node

:\>gedit /usr/local/bin/node
#!/bin/bash
exec /nodejs "$@"

sudo chmod -x /usr/local/bin/node

That ought to make

node Server.js 

work just fine

For completeness - adding to accepted answer above - in case you are interested in any sibling regardless of the element type you can use variation:

following-sibling::*

Try this little gem of a variation:

text-shadow:0 1px 1px rgba(255, 255, 255, 0.5);

I usually take "there's no answer" as a challenge

Replace

if (typeof obj === 'undefined') { return undefined;} // return undefined for undefined
if (obj === 'null') { return null;} // null unchanged

with

if (obj === undefined) { return undefined;} // return undefined for undefined 
if (obj === null) { return null;} // null unchanged

Either you can change the button type to submit

<button type="submit"  onclick="submitform()" id="save">Save</button>

Or you can hide the submit button, keep another button with type="button" and have click event for that button

<form>
    <button style="display: none;" type="submit" >Hidden button</button>
    <button type="button" onclick="submitForm()">Submit</button>
</form>

<?php header("Access-Control-Allow-Origin: http://example.com"); ?>

This command disables only first console warning info

console

Result: console result

On production servers I rename vendor to vendor-<datetime>, and during deployment will have two vendor dirs.

A HTTP cookie causes my system to choose the new vendor autoload.php, and after testing I do a fully atomic/instant switch between them to disable the old vendor dir for all future requests, then I delete the previous dir a few days later.

This avoids any problem caused by filesystem caches I'm using in apache/php, and also allows any active PHP code to continue using the previous vendor dir.

Despite other answers recommending against it, I personally run composer install on the server, since this is faster than rsync from my staging area (a VM on my laptop).

I use --no-dev --no-scripts --optimize-autoloader. You should read the docs for each one to check if this is appropriate on your environment.

I've found this answer in the site https://plainjs.com/javascript/styles/set-and-get-css-styles-of-elements-53/.

In this code we add multiple styles in an element:

let_x000D_
    element = document.querySelector('span')_x000D_
  , cssStyle = (el, styles) => {_x000D_
      for (var property in styles) {_x000D_
          el.style[property] = styles[property];_x000D_
      }_x000D_
  }_x000D_
;_x000D_
_x000D_
cssStyle(element, { background:'tomato', color: 'white', padding: '0.5rem 1rem'});

span{_x000D_
font-family: sans-serif;_x000D_
color: #323232;_x000D_
background: #fff;_x000D_
}

<span>_x000D_
lorem ipsum_x000D_
</span>

For anyone who is looking to enable this on the Mac version, it is not available. Developers of Visual Studio stated they will include in their roadmap.

It's probably best to use the Python Image Library to do this which I'm afraid is a separate download.

The easiest way to do what you want is via the load() method on the Image object which returns a pixel access object which you can manipulate like an array:

from PIL import Image

im = Image.open('dead_parrot.jpg') # Can be many different formats.
pix = im.load()
print im.size  # Get the width and hight of the image for iterating over
print pix[x,y]  # Get the RGBA Value of the a pixel of an image
pix[x,y] = value  # Set the RGBA Value of the image (tuple)
im.save('alive_parrot.png')  # Save the modified pixels as .png

Alternatively, look at ImageDraw which gives a much richer API for creating images.

I came across this post w/a similar issue. My fix was to add a hidden field to hold my invalid state for me.

<input type="hidden" ng-model="vm.application.isValid" required="" />

In my case I had a nullable bool which a person had to select one of two different buttons. if they answer yes, an entity is added to the collection and the state of the button changes. Until all of the questions get answered, (one of the buttons in each of the pairs has a click) the form is not valid.

vm.hasHighSchool = function (attended) { 
  vm.application.hasHighSchool = attended;
  applicationSvc.addSchool(attended, 1, vm.application);
}

<input type="hidden" ng-model="vm.application.hasHighSchool" required="" />
<div class="row">
  <div class="col-lg-3"><label>Did You Attend High School?</label><label class="required" ng-hide="vm.application.hasHighSchool != undefined">*</label></div>
  <div class="col-lg-2">
    <button value="Yes" title="Yes" ng-click="vm.hasHighSchool(true)" class="btn btn-default" ng-class="{'btn-success': vm.application.hasHighSchool == true}">Yes</button>
    <button value="No" title="No" ng-click="vm.hasHighSchool(false)" class="btn btn-default" ng-class="{'btn-success':  vm.application.hasHighSchool == false}">No</button>
  </div>
</div>

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

My easiest solution with jquery is:

$.ajax({
    url: "/scripts/advertisement.js", // this is just an empty js file
    dataType: "script"
}).fail(function () {
    // redirect or display message here
});

advertisement.js just contains nothing. When somebody uses adblock, it fails and the function gets called.

Just put this blur view on the imageView. Here is an example in Objective-C:

UIVisualEffect *blurEffect;
blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];

UIVisualEffectView *visualEffectView;
visualEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];

visualEffectView.frame = imageView.bounds;
[imageView addSubview:visualEffectView];

and Swift:

var visualEffectView = UIVisualEffectView(effect: UIBlurEffect(style: .Light))    

visualEffectView.frame = imageView.bounds

imageView.addSubview(visualEffectView)

Adding params keyword itself shows that you can pass multiple number of parameters while calling that method which is not possible without using it. To be more specific:

static public int addTwoEach(params int[] args)
{
    int sum = 0;

    foreach (var item in args)
    {
        sum += item + 2;
    }

    return sum;
}

When you will call above method you can call it by any of the following ways:

1. addTwoEach()
2. addTwoEach(1)
3. addTwoEach(new int[]{ 1, 2, 3, 4 })

But when you will remove params keyword only third way of the above given ways will work fine. For 1st and 2nd case you will get an error.

The process for timing out an operations is described in the documentation for signal.

The basic idea is to use signal handlers to set an alarm for some time interval and raise an exception once that timer expires.

Note that this will only work on UNIX.

Here's an implementation that creates a decorator (save the following code as timeout.py).

from functools import wraps
import errno
import os
import signal

class TimeoutError(Exception):
    pass

def timeout(seconds=10, error_message=os.strerror(errno.ETIME)):
    def decorator(func):
        def _handle_timeout(signum, frame):
            raise TimeoutError(error_message)

        def wrapper(*args, **kwargs):
            signal.signal(signal.SIGALRM, _handle_timeout)
            signal.alarm(seconds)
            try:
                result = func(*args, **kwargs)
            finally:
                signal.alarm(0)
            return result

        return wraps(func)(wrapper)

    return decorator

This creates a decorator called @timeout that can be applied to any long running functions.

So, in your application code, you can use the decorator like so:

from timeout import timeout

# Timeout a long running function with the default expiry of 10 seconds.
@timeout
def long_running_function1():
    ...

# Timeout after 5 seconds
@timeout(5)
def long_running_function2():
    ...

# Timeout after 30 seconds, with the error "Connection timed out"
@timeout(30, os.strerror(errno.ETIMEDOUT))
def long_running_function3():
    ...

C++11 standard on jumping over some initializations

JohannesD gave an explanation, now for the standards.

The C++11 N3337 standard draft 6.7 "Declaration statement" says:

3 It is possible to transfer into a block, but not in a way that bypasses declarations with initialization. A program that jumps (87) from a point where a variable with automatic storage duration is not in scope to a point where it is in scope is ill-formed unless the variable has scalar type, class type with a trivial default constructor and a trivial destructor, a cv-qualified version of one of these types, or an array of one of the preceding types and is declared without an initializer (8.5).

87) The transfer from the condition of a switch statement to a case label is considered a jump in this respect.

[ Example:

void f() {
   // ...
  goto lx;    // ill-formed: jump into scope of a
  // ...
ly:
  X a = 1;
  // ...
lx:
  goto ly;    // OK, jump implies destructor
              // call for a followed by construction
              // again immediately following label ly
}

— end example ]

As of GCC 5.2, the error message now says:

crosses initialization of

C

C allows it: c99 goto past initialization

The C99 N1256 standard draft Annex I "Common warnings" says:

2 A block with initialization of an object that has automatic storage duration is jumped into

The power in dBm is the 10 times the logarithm of the ratio of actual Power/1 milliWatt.

dBm stands for "decibel milliwatts". It is a convenient way to measure power. The exact formula is

P(dBm) = 10 · log10( P(W) / 1mW ) 

where

P(dBm) = Power expressed in dBm   
P(W) = the absolute power measured in Watts   
mW = milliWatts   
log10 = log to base 10

From this formula, the power in dBm of 1 Watt is 30 dBm. Because the calculation is logarithmic, every increase of 3dBm is approximately equivalent to doubling the actual power of a signal.

There is a conversion calculator and a comparison table here. There is also a comparison table on the Wikipedia english page, but the value it gives for mobile networks is a bit off.

Your actual question was "does the - sign count?"

The answer is yes, it does.

-85 dBm is less powerful (smaller) than -60 dBm. To understand this, you need to look at negative numbers. Alternatively, think about your bank account. If you owe the bank 85 dollars/rands/euros/rupees (-85), you're poorer than if you only owe them 65 (-65), i.e. -85 is smaller than -65. Also, in temperature measurements, -85 is colder than -65 degrees.

Signal strengths for mobile networks are always negative dBm values, because the transmitted network is not strong enough to give positive dBm values.

How will this affect your location finding? I have no idea, because I don't know what technology you are using to estimate the location. The values you quoted correspond roughly to a 5 bar network in GSM, UMTS or LTE, so you shouldn't have be having any problems due to network strength.

write java program that enter elapsed time in seconds for any cycling event & the output format should be like (hour : minute : seconds ) for EX : elapsed time in 4150 seconds= 1:09:10

At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.

It could look like this:

LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here

FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();   

Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();

Simply choose whatever Integer value you want for the ID:

rowLayout.setId(12345);

If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.

UPDATE:

Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".

MainActivity.java:

public class MainActivity extends Activity {

    @SuppressLint("NewApi")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);     

        LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);

        LinearLayout ll = new LinearLayout(this);
        ll.setOrientation(LinearLayout.HORIZONTAL);

        ll.setId(12345);

        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
        getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();

        fragContainer.addView(ll);
    }
}

TestFragment.java:

public class TestFragment extends Fragment {

    public static TestFragment newInstance(String text) {

        TestFragment f = new TestFragment();

        Bundle b = new Bundle();
        b.putString("text", text);
        f.setArguments(b);
        return f;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View v =  inflater.inflate(R.layout.fragment, container, false);

        ((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));     
        return v;
    }
}

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rlMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <LinearLayout
        android:id="@+id/llFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="19dp"
        android:orientation="vertical" >
    </LinearLayout>
</RelativeLayout>

fragment.xml:

  <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="200dp"
    android:layout_height="200dp" >

    <TextView
        android:id="@+id/tvFragText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="" />

</RelativeLayout>

And this is the result of the above code: (the two Fragments are aligned next to each other)

You need to intent your current context to another activity first with startActivity. After that you can finish your current activity from where you redirect.

 Intent intent = new Intent(this, FirstActivity.class);// New activity
 intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
 startActivity(intent);
 finish(); // Call once you redirect to another activity

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) - Clears the activity stack. If you don't want to clear the activity stack. PLease don't use that flag then.

getContext() method helps to use the Context of the class in a fragment activity.

Like explained in other answers you need to provide a comparison function. If you would like to keep the definition of that function close to the sort call (e.g. if it only makes sense for this sort) you can define it right there with boost::lambda. Use boost::lambda::bind to call the member function.

To e.g. sort by member variable or function data1:

#include <algorithm>
#include <vector>
#include <boost/lambda/bind.hpp>
#include <boost/lambda/lambda.hpp>
using boost::lambda::bind;
using boost::lambda::_1;
using boost::lambda::_2;

std::vector<myclass> object(10000);
std::sort(object.begin(), object.end(),
    bind(&myclass::data1, _1) < bind(&myclass::data1, _2));

There is Task exists, It is unnesscery using BackgroundWorker, Task is more simple. for example:

ProgressDialog.cs:

   public partial class ProgressDialog : Form
    {
        public System.Windows.Forms.ProgressBar Progressbar { get { return this.progressBar1; } }

        public ProgressDialog()
        {
            InitializeComponent();
        }

        public void RunAsync(Action action)
        {
            Task.Run(action);
        }
    }

Done! Then you can reuse ProgressDialog anywhere:

var progressDialog = new ProgressDialog();
progressDialog.Progressbar.Value = 0;
progressDialog.Progressbar.Maximum = 100;

progressDialog.RunAsync(() =>
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000)
        this.progressDialog.Progressbar.BeginInvoke((MethodInvoker)(() => {
            this.progressDialog.Progressbar.Value += 1;
        }));
    }
});

progressDialog.ShowDialog();

preg_replace shim with eval support

This is very inadvisable. But if you're not a programmer, or really prefer terrible code, you could use a substitute preg_replace function to keep your /e flag working temporarily.

/**
 * Can be used as a stopgap shim for preg_replace() calls with /e flag.
 * Is likely to fail for more complex string munging expressions. And
 * very obviously won't help with local-scope variable expressions.
 *
 * @license: CC-BY-*.*-comment-must-be-retained
 * @security: Provides `eval` support for replacement patterns. Which
 *   poses troubles for user-supplied input when paired with overly
 *   generic placeholders. This variant is only slightly stricter than
 *   the C implementation, but still susceptible to varexpression, quote
 *   breakouts and mundane exploits from unquoted capture placeholders.
 * @url: https://stackoverflow.com/q/15454220
 */
function preg_replace_eval($pattern, $replacement, $subject, $limit=-1) {
    # strip /e flag
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    # warn about most blatant misuses at least
    if (preg_match('/\(\.[+*]/', $pattern)) {
        trigger_error("preg_replace_eval(): regex contains (.*) or (.+) placeholders, which easily causes security issues for unconstrained/user input in the replacement expression. Transform your code to use preg_replace_callback() with a sane replacement callback!");
    }
    # run preg_replace with eval-callback
    return preg_replace_callback(
        $pattern,
        function ($matches) use ($replacement) {
            # substitute $1/$2/… with literals from $matches[]
            $repl = preg_replace_callback(
                '/(?<!\\\\)(?:[$]|\\\\)(\d+)/',
                function ($m) use ($matches) {
                    if (!isset($matches[$m[1]])) { trigger_error("No capture group for '$m[0]' eval placeholder"); }
                    return addcslashes($matches[$m[1]], '\"\'\`\$\\\0'); # additionally escapes '$' and backticks
                },
                $replacement
            );
            # run the replacement expression
            return eval("return $repl;");
        },
        $subject,
        $limit
    );
}

In essence, you just include that function in your codebase, and edit preg_replace to preg_replace_eval wherever the /e flag was used.

Pros and cons:

• Really just tested with a few samples from Stack Overflow.
• Does only support the easy cases (function calls, not variable lookups).
• Contains a few more restrictions and advisory notices.
• Will yield dislocated and less comprehensible errors for expression failures.
• However is still a usable temporary solution and doesn't complicate a proper transition to preg_replace_callback.
• And the license comment is just meant to deter people from overusing or spreading this too far.

Replacement code generator

Now this is somewhat redundant. But might help those users who are still overwhelmed with manually restructuring their code to preg_replace_callback. While this is effectively more time consuming, a code generator has less trouble to expand the /e replacement string into an expression. It's a very unremarkable conversion, but likely suffices for the most prevalent examples.

To use this function, edit any broken preg_replace call into preg_replace_eval_replacement and run it once. This will print out the according preg_replace_callback block to be used in its place.

/**
 * Use once to generate a crude preg_replace_callback() substitution. Might often
 * require additional changes in the `return …;` expression. You'll also have to
 * refit the variable names for input/output obviously.
 *
 * >>>  preg_replace_eval_replacement("/\w+/", 'strtopupper("$1")', $ignored);
 */
function preg_replace_eval_replacement($pattern, $replacement, $subjectvar="IGNORED") {
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    $replacement = preg_replace_callback('/[\'\"]?(?<!\\\\)(?:[$]|\\\\)(\d+)[\'\"]?/', function ($m) { return "\$m[{$m[1]}]"; }, $replacement);
    $ve = "var_export";
    $bt = debug_backtrace(0, 1)[0];
    print "<pre><code>
    #----------------------------------------------------
    # replace preg_*() call in '$bt[file]' line $bt[line] with:
    #----------------------------------------------------
    \$OUTPUT_VAR = preg_replace_callback(
        {$ve($pattern, TRUE)},
        function (\$m) {
            return {$replacement};
        },
        \$YOUR_INPUT_VARIABLE_GOES_HERE
    )
    #----------------------------------------------------
    </code></pre>\n";
}

Take in mind that mere copy&pasting is not programming. You'll have to adapt the generated code back to your actual input/output variable names, or usage context.

• Specificially the $OUTPUT = assignment would have to go if the previous preg_replace call was used in an if.
• It's best to keep temporary variables or the multiline code block structure though.

And the replacement expression may demand more readability improvements or rework.

• For instance stripslashes() often becomes redundant in literal expressions.
• Variable-scope lookups require a use or global reference for/within the callback.
• Unevenly quote-enclosed "-$1-$2" capture references will end up syntactically broken by the plain transformation into "-$m[1]-$m[2].

The code output is merely a starting point. And yes, this would have been more useful as an online tool. This code rewriting approach (edit, run, edit, edit) is somewhat impractical. Yet could be more approachable to those who are accustomed to task-centric coding (more steps, more uncoveries). So this alternative might curb a few more duplicate questions.

You can use

The OP doesn't mention if this is DB2/400 being discussed, but I found that the only way I could get the table structure including the column name descriptions was to use DSPFFD.

DSPFFD FILE(TBNAME) OUTPUT(*OUTFILE) OUTFILE(SOMELIB/TBDESC)

This puts the description of TBNAME in a table called TBDESC in the SOMELIB library. You can then query that with:

select * from SOMELIB/TBDESC

content doesn't support HTML, only text. You should probably use javascript, jQuery or something like that.

Another problem with your code is " inside a " block. You should mix ' and " (class='headingDetail').

If content did support HTML you could end up in an infinite loop where content is added inside content.

Use iloc to access by position (rather than label):

In [11]: df = pd.DataFrame([[1, 2], [3, 4]], ['a', 'b'], ['A', 'B'])

In [12]: df
Out[12]: 
   A  B
a  1  2
b  3  4

In [13]: df.iloc[0]  # first row in a DataFrame
Out[13]: 
A    1
B    2
Name: a, dtype: int64

In [14]: df['A'].iloc[0]  # first item in a Series (Column)
Out[14]: 1

Also you might consider the Wi-Fi adapter's MAC address. Retrieved like this:

WifiManager wm = (WifiManager)Ctxt.getSystemService(Context.WIFI_SERVICE);
return wm.getConnectionInfo().getMacAddress();

Requires permission android.permission.ACCESS_WIFI_STATE in the manifest.

Reported to be available even when Wi-Fi is not connected. If Joe from the answer above gives this one a try on his many devices, that'd be nice.

On some devices, it's not available when Wi-Fi is turned off.

NOTE: From Android 6.x, it returns consistent fake mac address: 02:00:00:00:00:00

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

Are you using Webfonts from Google, Typekit, etc? There are multiple ways you could use Webfonts like @font-face or CSS3 methods, some browsers like Firefox & IE may refuse to embed the font when it’s coming from some non-standard 3rd party URL (like your blog) for same security reason.

I also just found out how to do this with the Excel Name Manager (Formulas > Defined Names Section > Name Manager).

You can define a variable that doesn't have to "live" within a cell and then you can use it in formulas.

This question was asked before Java 7 release but now, there is another possible way using Java 7 (and above) API:

double random = ThreadLocalRandom.current().nextDouble(min, max);

nextDouble will return a pseudorandom double value between the minimum (inclusive) and the maximum (exclusive). The bounds are not necessarily int, and can be double.

In my case this was caused by an integer overflow. I had a UInt16, and was doubling the value to put into an Int. The faulty code was

let result = Int(myUInt16 * 2)

However, this multiplies as a UInt16, then converts to Int. So if myUInt16 contains a value over 32767 then an overflow occurs.

All was well once I corrected the code to

let result = Int(myUint16) * 2

Basically, don't use ArrayList.toString() - build the string up for yourself. For example:

StringBuilder builder = new StringBuilder();
for (String value : publicArray) {
    builder.append(value);
}
String text = builder.toString();

(Personally I wouldn't call the variable publicArray when it's not actually an array, by the way.)

You can use above function for casting not similar class objects (PHP >= 5.3)

/**
 * Class casting
 *
 * @param string|object $destination
 * @param object $sourceObject
 * @return object
 */
function cast($destination, $sourceObject)
{
    if (is_string($destination)) {
        $destination = new $destination();
    }
    $sourceReflection = new ReflectionObject($sourceObject);
    $destinationReflection = new ReflectionObject($destination);
    $sourceProperties = $sourceReflection->getProperties();
    foreach ($sourceProperties as $sourceProperty) {
        $sourceProperty->setAccessible(true);
        $name = $sourceProperty->getName();
        $value = $sourceProperty->getValue($sourceObject);
        if ($destinationReflection->hasProperty($name)) {
            $propDest = $destinationReflection->getProperty($name);
            $propDest->setAccessible(true);
            $propDest->setValue($destination,$value);
        } else {
            $destination->$name = $value;
        }
    }
    return $destination;
}

EXAMPLE:

class A 
{
  private $_x;   
}

class B 
{
  public $_x;   
}

$a = new A();
$b = new B();

$x = cast('A',$b);
$x = cast('B',$a);

Everything in the java.lang package is implicitly imported (including String) and you do not need to do so yourself. This is simply a feature of the Java language. ArrayList and HashMap are however in the java.util package, which is not implicitly imported.

The package java.lang mostly includes essential features, such a class version of primitives, basic exceptions and the Object class. This being integral to most programs, forcing people to import them is redundant and thus the contents of this package are implicitly imported.

Please have a look at the fiddle, http://jsfiddle.net/yNXS2/. Since the directive you created didn't created a new scope i continued in the way.

$scope.test = function(){... made that happen.

you can use valign="top" on the td tag it is working perfectly for me.

As Daniel A. White said in his comment, the OPTIONS request is most likely created by the client as part of a cross domain JavaScript request. This is done automatically by Cross Origin Resource Sharing (CORS) compliant browsers. The request is a preliminary or pre-flight request, made before the actual AJAX request to determine which request verbs and headers are supported for CORS. The server can elect to support it for none, all or some of the HTTP verbs.

To complete the picture, the AJAX request has an additional "Origin" header, which identified where the original page which is hosting the JavaScript was served from. The server can elect to support request from any origin, or just for a set of known, trusted origins. Allowing any origin is a security risk since is can increase the risk of Cross site Request Forgery (CSRF).

So, you need to enable CORS.

Here is a link that explains how to do this in ASP.Net Web API

http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api#enable-cors

The implementation described there allows you to specify, amongst other things

• CORS support on a per-action, per-controller or global basis
• The supported origins
• When enabling CORS a a controller or global level, the supported HTTP verbs
• Whether the server supports sending credentials with cross-origin requests

In general, this works fine, but you need to make sure you are aware of the security risks, especially if you allow cross origin requests from any domain. Think very carefully before you allow this.

In terms of which browsers support CORS, Wikipedia says the following engines support it:

• Gecko 1.9.1 (FireFox 3.5)
• WebKit (Safari 4, Chrome 3)
• MSHTML/Trident 6 (IE10) with partial support in IE8 and 9
• Presto (Opera 12)

Your file seems quite small (297 lines) so you can read and write them quite quickly. You refer to Excel CSV, which does not exists, and you show space delimited data in your example. Furthermore, Access is limited to 255 columns, and a CSV is not, so there is no guarantee this will work

Sub StripHeaderAndFooter()
Dim fs As Object ''FileSystemObject
Dim tsIn As Object, tsOut As Object ''TextStream
Dim sFileIn As String, sFileOut As String
Dim aryFile As Variant

    sFileIn = "z:\docs\FileName.csv"
    sFileOut = "z:\docs\FileOut.csv"

    Set fs = CreateObject("Scripting.FileSystemObject")
    Set tsIn = fs.OpenTextFile(sFileIn, 1) ''ForReading

    sTmp = tsIn.ReadAll

    Set tsOut = fs.CreateTextFile(sFileOut, True) ''Overwrite
    aryFile = Split(sTmp, vbCrLf)

    ''Start at line 3 and end at last line -1
    For i = 3 To UBound(aryFile) - 1
        tsOut.WriteLine aryFile(i)
    Next

    tsOut.Close

    DoCmd.TransferText acImportDelim, , "NewCSV", sFileOut, False
End Sub

Edit re various comments

It is possible to import a text file manually into MS Access and this will allow you to choose you own cell delimiters and text delimiters. You need to choose External data from the menu, select your file and step through the wizard.

About importing and linking data and database objects -- Applies to: Microsoft Office Access 2003

Introduction to importing and exporting data -- Applies to: Microsoft Access 2010

Once you get the import working using the wizards, you can save an import specification and use it for you next DoCmd.TransferText as outlined by @Olivier Jacot-Descombes. This will allow you to have non-standard delimiters such as semi colon and single-quoted text.

The major difference between Page_Load and Page_PreRender is that in the Page_Load method not all of your page controls are completely initialized (loaded), because individual controls Load() methods has not been called yet. This means that tree is not ready for rendering yet. In Page_PreRender you guaranteed that all page controls are loaded and ready for rendering. Technically Page_PreRender is your last chance to tweak the page before it turns into HTML stream.

Use a packet analyzer to intercept the packets to/from somewhere.com. Studying those packets should tell you what is going on.

Time-outs or connections refused could mean that the remote host is too busy.

USING A VISUAL DIFF TOOL

The Default Answer (at the command line)

The top answers here correctly show how to view the cached/staged changes in the Index:

$ git diff --cached

or $ git diff --staged which is an alias.

Launching the Visual Diff Tool Instead

The default answer will spit out the diff changes at the git bash (i.e. on the command line or in the console). For those who prefer a visual representation of the staged file differences, there is a script available within git which launches a visual diff tool for each file viewed rather than showing them on the command line, called difftool:

$ git difftool --staged

This will do the same this as git diff --staged, except any time the diff tool is run (i.e. every time a file is processed by diff), it will launch the default visual diff tool (in my environment, this is kdiff3).

After the tool launches, the git diff script will pause until your visual diff tool is closed. Therefore, you will need to close each file in order to see the next one.

You Can Always Use difftool in place of diff in git commands

For all your visual diff needs, git difftool will work in place of any git diff command, including all options.

For example, to have the visual diff tool launch without asking whether to do it for each file, add the -y option (I think usually you'll want this!!):

$ git difftool -y --staged

In this case it will pull up each file in the visual diff tool, one at a time, bringing up the next one after the tool is closed.

Or to look at the diff of a particular file that is staged in the Index:

$ git difftool -y --staged <<relative path/filename>>

For all the options, see the man page:

$ git difftool --help

Setting up Visual Git Tool

To use a visual git tool other than the default, use the -t <tool> option:

$ git difftool -t <tool> <<other args>>

Or, see the difftool man page for how to configure git to use a different default visual diff tool.

Example .gitconfig entries for vscode as diff/merge tool

Part of setting up a difftool involves changing the .gitconfig file, either through git commands that change it behind the scenes, or editing it directly.

You can find your .gitconfig in your home directory,such as ~ in Unix or normally c:\users\<username> on Windows).

Or, you can open the user .gitconfig in your default Git editor with git config -e --global.

Here are example entries in my global user .gitconfig for VS Code as both diff tool and merge tool:

[diff]
    tool = vscode
    guitool = vscode
[merge]
    tool = vscode
    guitool = vscode
[mergetool]
    prompt = true
[difftool "vscode"]
    cmd = code --wait --diff \"$LOCAL\" \"$REMOTE\"
    path = c:/apps/vscode/code.exe
[mergetool "vscode"]
    cmd = code --wait \"$MERGED\"
    path = c:/apps/vscode/code.exe

The one-liner solution is more useful as a shibboleth than good code; good Perl coders will know it and understand it, but it's much less transparent and readable than the two-line copy-and-modify couplet you're starting with.

In other words, a good way to do this is the way you're already doing it. Unnecessary concision at the cost of readability isn't a win.

The readonly keyword is different from the const keyword. A const field can only be initialized at the declaration of the field. A readonly field can be initialized either at the declaration or in a constructor. Therefore, readonly fields can have different values depending on the constructor used. Also, while a const field is a compile-time constant, the readonly field can be used for runtime constants

Short and clear MSDN reference here

I think this is the best way to do it !

<html>
<body onload="document.getElementById('redirectForm').submit()">
<form id='redirectForm' method='POST' action='/done.html'>
<input type='hidden' name='status' value='complete'/>
<input type='hidden' name='id' value='0u812'/>
<input type='submit' value='Please Click Here To Continue'/>
</form>
</body>
</html>

This will be almost instantaneous and user won't see anything !

I just had the situation that I wanted this only for lines exceeding \linewidth, that is: Squeezing long lines slightly. Since it took me hours to figure this out, I would like to add it here.

I want to emphasize that scaling fonts in LaTeX is a deadly sin! In nearly every situation, there is a better way (e.g. multline of the mathtools package). So use it conscious.

In this particular case, I had no influence on the code base apart the preamble and some lines slightly overshooting the page border when I compiled it as an eBook-scaled pdf.

\usepackage{environ}         % provides \BODY
\usepackage{etoolbox}        % provides \ifdimcomp
\usepackage{graphicx}        % provides \resizebox

\newlength{\myl}
\let\origequation=\equation
\let\origendequation=\endequation

\RenewEnviron{equation}{
  \settowidth{\myl}{$\BODY$}                       % calculate width and save as \myl
  \origequation
  \ifdimcomp{\the\linewidth}{>}{\the\myl}
  {\ensuremath{\BODY}}                             % True
  {\resizebox{\linewidth}{!}{\ensuremath{\BODY}}}  % False
  \origendequation
}

Before After

Here is my solution. I think it is simpler. It only expands the view but can easy be extended.

public class WidthExpandAnimation extends Animation
{
    int _targetWidth;
    View _view;

    public WidthExpandAnimation(View view)
    {
        _view = view;
    }

    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t)
    {
        if (interpolatedTime < 1.f)
        {
            int newWidth = (int) (_targetWidth * interpolatedTime);

            _view.layout(_view.getLeft(), _view.getTop(),
                    _view.getLeft() + newWidth, _view.getBottom());
        }
        else
            _view.requestLayout();
    }

    @Override
    public void initialize(int width, int height, int parentWidth, int parentHeight)
    {
        super.initialize(width, height, parentWidth, parentHeight);

        _targetWidth = width;
    }

    @Override
    public boolean willChangeBounds() {
        return true;
    }
}

The connectivity plugin states in its docs that it only provides information if there is a network connection, but not if the network is connected to the Internet

Note that on Android, this does not guarantee connection to Internet. For instance, the app might have wifi access but it might be a VPN or a hotel WiFi with no access.

You can use

import 'dart:io';
...
try {
  final result = await InternetAddress.lookup('google.com');
  if (result.isNotEmpty && result[0].rawAddress.isNotEmpty) {
    print('connected');
  }
} on SocketException catch (_) {
  print('not connected');
}

Here is a generic working solution based on @Beta's

I'm using GNU Make 4.1 with SHELL=/bin/bash atop my Makefile, so YMMV!

This allows us to accept extra arguments (by doing nothing when we get a job that doesn't match, rather than throwing an error).

%:
    @:

And this is a macro which gets the args for us:

args = `arg="$(filter-out $@,$(MAKECMDGOALS))" && echo $${arg:-${1}}`

Here is a job which might call this one:

test:
    @echo $(call args,defaultstring)

The result would be:

$ make test
defaultstring
$ make test hi
hi

Note! You might be better off using a "Taskfile", which is a bash pattern that works similarly to make, only without the nuances of Maketools. See https://github.com/adriancooney/Taskfile

Removing the web.config-file from the IIS Directory Folder solves the problem.

The answer is no because SparseArray doesn't provide it. As pst put it, this thing doesn't provide any interfaces.

You could loop from 0 - size() and skip values that return null, but that is about it.

As I state in my comment, if you need to iterate use a Map instead of a SparseArray. For example, use a TreeMap which iterates in order by the key.

TreeMap<Integer, MyType>

Try this

var URL = "scratch.mit.edu/projects";
var mainURL = window.location.pathname;

if (mainURL == URL) {
    mainURL += ( mainURL.match( /[\?]/g ) ? '&' : '#' ) + '_bypasssharerestrictions_';
    console.log(mainURL)
}

I have Windows 10 and PowerShell 5.1 was already installed. For whatever reason the x86 version works and can find "Install-Module", but the other version cannot.

Search your Start Menu for "powershell", and find the entry that ends in "(x86)":

Here is what I experience between the two different versions:

You can't do it with pure PHP. You must do it with JavaScript. There are several articles written on how to do this.

Essentially, you can set a cookie or you can even do some Ajax to send the info to a PHP script. If you use jQuery, you can do it something like this:

jquery:

$(function() {
    $.post('some_script.php', { width: screen.width, height:screen.height }, function(json) {
        if(json.outcome == 'success') {
            // do something with the knowledge possibly?
        } else {
            alert('Unable to let PHP know what the screen resolution is!');
        }
    },'json');
});

PHP (some_script.php)

<?php
// For instance, you can do something like this:
if(isset($_POST['width']) && isset($_POST['height'])) {
    $_SESSION['screen_width'] = $_POST['width'];
    $_SESSION['screen_height'] = $_POST['height'];
    echo json_encode(array('outcome'=>'success'));
} else {
    echo json_encode(array('outcome'=>'error','error'=>"Couldn't save dimension info"));
}
?>

All that is really basic but it should get you somewhere. Normally screen resolution is not what you really want though. You may be more interested in the size of the actual browser's view port since that is actually where the page is rendered...

So I wrote a function that would get the POST data from the php://input stream.

So the challenge here was switching to PUT, DELETE OR PATCH request method, and still obtain the post data that was sent with that request.

I'm sharing this maybe for someone with a similar challenge. The function below is what I came up with and it works. I hope it helps!

    /**
     * @method Post getPostData
     * @return array
     * 
     * Convert Content-Disposition to a post data
     */
    function getPostData() : array
    {
        // @var string $input
        $input = file_get_contents('php://input');

        // continue if $_POST is empty
        if (strlen($input) > 0 && count($_POST) == 0 || count($_POST) > 0) :

            $postsize = "---".sha1(strlen($input))."---";

            preg_match_all('/([-]{2,})([^\s]+)[\n|\s]{0,}/', $input, $match);

            // update input
            if (count($match) > 0) $input = preg_replace('/([-]{2,})([^\s]+)[\n|\s]{0,}/', '', $input);

            // extract the content-disposition
            preg_match_all("/(Content-Disposition: form-data; name=)+(.*)/m", $input, $matches);

            // let's get the keys
            if (count($matches) > 0 && count($matches[0]) > 0)
            {
                $keys = $matches[2];

                foreach ($keys as $index => $key) :
                    $key = trim($key);
                    $key = preg_replace('/^["]/','',$key);
                    $key = preg_replace('/["]$/','',$key);
                    $key = preg_replace('/[\s]/','',$key);

The problem is in your JSP, most likely you are calling a method on an object that is null at runtime.

It is happening in the _jspInit() call, which is a little more unusual... the problem code is probably a method declaration like <%! %>

Update: I've only reproduced this by overriding the _jspInit() method. Is that what you're doing? If so, it's not recommended - that's why it starts with an _.

you should calculate the complexity of algorithms used by the methods OrderBy and Sort. QuickSort has a complexity of n (log n) as i remember, where n is the length of the array.

i've searched for orderby's too, but i could not find any information even in msdn library. if you have not any same values and sorting related to only one property, i prefer to use Sort() method; if not than use OrderBy.

Click on the line or element you want to copy. Copy to clipboard. Paste.

The only tricky thing is if you click on a line, you get everything that line includes if it was folded. For example if you click on a div, and copy, you get everything that the div includes.

You can also get only what you want by Right Clicking, and select 'Edit as HTML'. This will make that section essentially text, with none of the folding activated. You can then select, copy and paste the relevant bits.

You need to iterate your list and call String#trim for searching:

String search = "A";
for(String str: myList) {
    if(str.trim().contains(search))
       return true;
}
return false;

OR if you want to perform ignore case search, then use:

search = search.toLowerCase(); // outside loop

// inside the loop
if(str.trim().toLowerCase().contains(search))

mysqli is the enhanced version of mysql.

PDO extension defines a lightweight, consistent interface for accessing databases in PHP. Each database driver that implements the PDO interface can expose database-specific features as regular extension functions.

They pretty much got it there... just like a checkbox, all you have to do is add the attribute checked="checked" like so:

<input type="radio" checked="checked">

...and you got it.

Cheers!

You could use CSS for this and create classes for the elements. So you'd have something like this

p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }

Then your HTML would read:

<p class="detail">My Name is: <span class="name">Tintinecute</span> </p>

It's a lot neater then inline stylesheets, is easier to maintain and provides greater reuse.

Here's the complete HTML to demonstrate what I mean:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <style type="text/css">
    p.detail { color:#4C4C4C;font-weight:bold;font-family:Calibri;font-size:20 }
    span.name { color:#FF0000;font-weight:bold;font-family:Tahoma;font-size:20 }
    </style>
</head>
<body>
    <p class="detail">My Name is: <span class="name">Tintinecute</span> </p>
</body>
</html>     

You'll see that I have the stylesheet classes in a style tag in the header, and then I only apply those classes in the code such as <p class="detail"> ... </p>. Go through the w3schools tutorial, it will only take a couple of hours and will really turn you around when it comes to styling your HTML elements. If you cut and paste that into an HTML document you can edit the styles and see what effect they have when you open the file in a browser. Experimenting like this is a great way to learn.

if the response is like this

"GetDataResult": "[{\"UserID\":1,\"DeviceID\":\"d1254\",\"MobileNO\":\"056688\",\"Pak1\":true,\"pak2\":true,\"pak3\":false,\"pak4\":true,\"pak5\":true,\"pak6\":false,\"pak7\":false,\"pak8\":true,\"pak9\":false,\"pak10\":true,\"pak11\":false,\"pak12\":false}]"

you can parse like this

JSONObject jobj=new JSONObject(response);
        String c = jobj.getString("GetDataResult");         
        JSONArray jArray = new JSONArray(c);
        deviceId=jArray.getJSONObject(0).getString("DeviceID");

here the JsonArray size is 1.Otherwise you should use for loop for getting values.

Add this at the start of main

ApplicationContext context = new ClassPathXmlApplicationContext("path/to/applicationContext.xml");

JobLauncher launcher=(JobLauncher)context.getBean("launcher");
Job job=(Job)context.getBean("job");

//Get as many beans you want
//Now do the thing you were doing inside test method
StopWatch sw = new StopWatch();
sw.start();
launcher.run(job, jobParameters);
sw.stop();
//initialize the log same way inside main
logger.info(">>> TIME ELAPSED:" + sw.prettyPrint());

The first push should be a:

git push -u origin branchname

That would make sure:

• your local branch has a remote tracking branch of the same name referring an upstream branch in your remote repo 'origin',
• this is compliant with the default push policy 'simple'

Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.

JavaBeans is a standard, and its basic syntax requirements have been clearly explained by the other answers.

However, IMO, it is more than a simple syntax standard. The real meaning or intended usage of JavaBeans is, together with various tool supports around the standard, to facilitate code reuse and component-based software engineering, i.e. enable developers to build applications by assembling existing components (classes) and without having to write any code (or only have to write a little glue code). Unfortunately this technology is way under-estimated and under-utilized by the industry, which can be told from the answers in this thread.

If you read Oracle's tutorial on JavaBeans, you can get a better understanding in that.

This happens because you have added your worker directory as a volume to your docker-compose.yml, as the volume is not mounted during the build.

When docker builds the image, the node_modules directory is created within the worker directory, and all the dependencies are installed there. Then on runtime the worker directory from outside docker is mounted into the docker instance (which does not have the installed node_modules), hiding the node_modules you just installed. You can verify this by removing the mounted volume from your docker-compose.yml.

A workaround is to use a data volume to store all the node_modules, as data volumes copy in the data from the built docker image before the worker directory is mounted. This can be done in the docker-compose.yml like this:

redis:
    image: redis
worker:
    build: ./worker
    command: npm start
    ports:
        - "9730:9730"
    volumes:
        - ./worker/:/worker/
        - /worker/node_modules
    links:
        - redis

I'm not entirely certain whether this imposes any issues for the portability of the image, but as it seems you are primarily using docker to provide a runtime environment, this should not be an issue.

If you want to read more about volumes, there is a nice user guide available here: https://docs.docker.com/userguide/dockervolumes/

EDIT: Docker has since changed it's syntax to require a leading ./ for mounting in files relative to the docker-compose.yml file.

You can change the color of the text in the toolbar with these:

<item name="android:textColorPrimary">#FFFFFF</item>
<item name="android:textColor">#FFFFFF</item>

Up to Postgres 11 generated columns are not supported - as defined in the SQL standard and implemented by some RDBMS including DB2, MySQL and Oracle. Nor the similar "computed columns" of SQL Server.

STORED generated columns are introduced with Postgres 12. Trivial example:

CREATE TABLE tbl (
  int1    int
, int2    int
, product bigint GENERATED ALWAYS AS (int1 * int2) STORED
);

db<>fiddle here

VIRTUAL generated columns may come with one of the next iterations. (Not in Postgres 13, yet) .

Related:

• Attribute notation for function call gives error

Until then, you can emulate VIRTUAL generated columns with a function using attribute notation (tbl.col) that looks and works much like a virtual generated column. That's a bit of a syntax oddity which exists in Postgres for historic reasons and happens to fit the case. This related answer has code examples:

• Store common query as column?

The expression (looking like a column) is not included in a SELECT * FROM tbl, though. You always have to list it explicitly.

Can also be supported with a matching expression index - provided the function is IMMUTABLE. Like:

CREATE FUNCTION col(tbl) ... AS ...  -- your computed expression here
CREATE INDEX ON tbl(col(tbl));

Alternatives

Alternatively, you can implement similar functionality with a VIEW, optionally coupled with expression indexes. Then SELECT * can include the generated column.

"Persisted" (STORED) computed columns can be implemented with triggers in a functionally identical way.

Materialized views are a closely related concept, implemented since Postgres 9.3.
In earlier versions one can manage MVs manually.

I have come across this with the Hero, using what I thought was a published API. In the end, I used a test to see if the intent could be received:

private boolean isCallable(Intent intent) {
    List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent, 
        PackageManager.MATCH_DEFAULT_ONLY);
    return list.size() > 0;
}

In use when I would usually just start the activity:

final Intent intent = new Intent("com.android.camera.action.CROP");
intent.setClassName("com.android.camera", "com.android.camera.CropImage");
if (isCallable(intent)) {
    // call the intent as you intended.
} else {
    // make alternative arrangements.
}

obvious: If you go down this route - using non-public APIs - you must absolutely provide a fallback which you know definitely works. It doesn't have to be perfect, it can be a Toast saying that this is unsupported for this handset/device, but you should avoid an uncaught exception. end obvious.

I find the Open Intents Registry of Intents Protocols quite useful, but I haven't found the equivalent of a TCK type list of intents which absolutely must be supported, and examples of what apps do different handsets.

1. You can print your variables out along the way
2. Turn on the -w (warnings) flag
3. Use a tool such as ruby-debug

These are few things which will help you in understanding everything... using iloc

In iloc, [initial row:ending row, initial column:ending column]

case 1: if you want only last column --- df.iloc[:,-1] & df.iloc[:,-1:] this means that you want only the last column...

case 2: if you want all columns and all rows except the last column --- df.iloc[:,:-1] this means that you want all columns and all rows except the last column...

case 3: if you want only last row --- df.iloc[-1:,:] & df.iloc[-1,:] this means that you want only the last row...

case 4: if you want all columns and all rows except the last row --- df.iloc[:-1,:] this means that you want all columns and all rows except the last column...

case 5: if you want all columns and all rows except the last row and last column --- df.iloc[:-1,:-1] this means that you want all columns and all rows except the last column and last row...

I had an example where I was looking up and because one table held the value as a double, the other as a string, they would not match (or not match without a cast). But only NOT IN. As SELECT ... IN ... worked. Weird, but thought I would share in case anyone else encounters this simple fix.

Wrapping your list of objects with another object containing a property that matches the name of the parameter which is expected by the MVC controller works. The important bit being the wrapper around the object list.

$(document).ready(function () {
    var employeeList = [
        { id: 1, name: 'Bob' },
        { id: 2, name: 'John' },
        { id: 3, name: 'Tom' }
    ];      

    var Employees = {
      EmployeeList: employeeList
    }

    $.ajax({
        dataType: 'json',
        type: 'POST',
        url: '/Employees/Process',
        data: Employees,
        success: function () {          
            $('#InfoPanel').html('It worked!');
        },
        failure: function (response) {          
            $('#InfoPanel').html(response);
        }
    }); 
});


public void Process(List<Employee> EmployeeList)
{
    var emps = EmployeeList;
}

public class Employee
{
    public int Id { get; set; }
    public string Name { get; set; }
}

According to the docs, you want to export of type del (the default delimiter looks like a comma, which is what you want). See the doc page for more information on the EXPORT command.

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

You can also use below format:

Label1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#22FF99");

and

HyperLink1.ForeColor = System.Drawing.ColorTranslator.FromHtml("#22FF99");

Apply the below code where you want to make code to exit application.

System.Windows.Forms.Application.Exit( )

Since explode() returns an array, you can add square brackets directly to the end of that function, if you happen to know the position of the last array item.

$email = '[email protected]';
$provider = explode('@', $email)[1];
echo $provider; // example.com

Or another way is list():

$email = '[email protected]';
list($prefix, $provider) = explode('@', $email);
echo $provider; // example.com

If you don't know the position:

$path = 'one/two/three/four';
$dirs = explode('/', $path);
$last_dir = $dirs[count($dirs) - 1];
echo $last_dir; // four

As of Android Studio 3.0 / Gradle Build Tools 3.0.0, APK artifacts can now be found in foo/bar/build/outputs/apk/flavorName/buildType with respect to your project name, foo, and your module name, bar. There is now a directory for each apk file sorted organized first by flavor (with respect to flavor dimensions) and then by build type.

A constructor allows you to initialize an object's properties upon creation of the object.

If you create a __construct() function, PHP will automatically call this function when you create an object from a class.

Solution for those who are interested in sending params and headers in GET request

$http.get('https://www.your-website.com/api/users.json', {
        params:  {page: 1, limit: 100, sort: 'name', direction: 'desc'},
        headers: {'Authorization': 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
    }
)
.then(function(response) {
    // Request completed successfully
}, function(x) {
    // Request error
});

Complete service example will look like this

var mainApp = angular.module("mainApp", []);

mainApp.service('UserService', function($http, $q){

   this.getUsers = function(page = 1, limit = 100, sort = 'id', direction = 'desc') {

        var dfrd = $q.defer();
        $http.get('https://www.your-website.com/api/users.json', 
            {
                params:{page: page, limit: limit, sort: sort, direction: direction},
                headers: {Authorization: 'Basic QWxhZGRpbjpvcGVuIHNlc2FtZQ=='}
            }
        )
        .then(function(response) {
            if ( response.data.success == true ) { 

            } else {

            }
        }, function(x) {

            dfrd.reject(true);
        });
        return dfrd.promise;
   }

});

Sometimes technicality is given where none is required, and while many of the top voted answers are accurately technical and specific, I personally don't think they are any more easy to understand, or succinct, as what can be found on Wikipedia, or in official documentation.

The way I like to think of JSON is exactly what it is - a language within a world of different languages. However, the difference between JSON and other languages is that "everyone" "speaks" JSON, along with their "native language."

Using a real world example, let's pretend we have three people. One person speaks Igbo as their native tongue. The second person would like to interact with the first person, however, the first person speaks Yoruba as their first language.

What can we do?

Thankfully, the third person in our example grew up speaking English, but also happens to speak both Igbo and Yoruba as second languages, and so can act as an intermediary between the first two individuals.

In the programming world, the first "person" is Python, the second "person" is Ruby, and the third "person" is JSON, who just so happens to be able to "translate" Ruby into Python and vice versa! Now obviously this analogy isn't a perfect one, but, as someone who is bilingual, I believe it's an easy way to look at how JSON interacts with other programming languages.

They're not actually characters, they're hexadecimal digits.

Create a new package under your project called "Devices" and place your class in it. This is equivalent to the class being placed in a directory called "Devices" in your project source folder.
