my good friend Alessandro have a nice post regarding bit operators in C#, you should read about it so you know what to do.

It's pretty easy. If you break down the IP given to you to binary, the network address is the ip address where all of the host bits (the 0's in the subnet mask) are 0,and the last address, the broadcast address, is where all the host bits are 1.

For example:

ip 192.168.33.72 mask 255.255.255.192

11111111.11111111.11111111.11000000 (subnet mask)
11000000.10101000.00100001.01001000 (ip address)

The bolded parts is the HOST bits (the rest are network bits). If you turn all the host bits to 0 on the IP, you get the first possible IP:

11000000.10101000.00100001.01000000 (192.168.33.64)

If you turn all the host bits to 1's, then you get the last possible IP (aka the broadcast address):

11000000.10101000.00100001.01111111 (192.168.33.127)

So for my example:

the network is "192.168.33.64/26":
Network address: 192.168.33.64
First usable: 192.168.33.65 (you can use the network address, but generally this is considered bad practice)
Last useable: 192.168.33.126
Broadcast address: 192.168.33.127

Try this:

ORDER BY 1, 2

OR

ORDER BY rsc.RadioServiceCodeId, rsc.RadioServiceCode + ' - ' + rsc.RadioService

android:background="#E1E1E1" 
// background add in layout
<EditText
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#ffffff">
</EditText>

Strings can be deep copied with

List<String> b = new ArrayList<String>(a);

because they are immutable. Every other Object not --> you need to iterate and do a copy by yourself.

Try

ChromeOptions options = new ChromeOptions();
options.addArguments("--start-fullscreen");

Swift syntax:

    UINavigationBar.appearance().barTintColor = UIColor.whiteColor() //changes the Bar Tint Color

I just put that in the AppDelegate didFinishLaunchingWithOptions and it persists throughout the app

Do NOT loop through all cells!! There is a lot of overhead in communications between worksheets and VBA, for both reading and writing. Looping through all cells will be agonizingly slow. I'm talking hours.

Instead, load an entire sheet at once into a Variant array. In Excel 2003, this takes about 2 seconds (and 250 MB of RAM). Then you can loop through it in no time at all.

In Excel 2007 and later, sheets are about 1000 times larger (1048576 rows × 16384 columns = 17 billion cells, compared to 65536 rows × 256 columns = 17 million in Excel 2003). You will run into an "Out of memory" error if you try to load the whole sheet into a Variant; on my machine I can only load 32 million cells at once. So you have to limit yourself to the range you know has actual data in it, or load the sheet bit by bit, e.g. 30 columns at a time.

Option Explicit

Sub test()

    Dim varSheetA As Variant
    Dim varSheetB As Variant
    Dim strRangeToCheck As String
    Dim iRow As Long
    Dim iCol As Long

    strRangeToCheck = "A1:IV65536"
    ' If you know the data will only be in a smaller range, reduce the size of the ranges above.
    Debug.Print Now
    varSheetA = Worksheets("Sheet1").Range(strRangeToCheck)
    varSheetB = Worksheets("Sheet2").Range(strRangeToCheck) ' or whatever your other sheet is.
    Debug.Print Now

    For iRow = LBound(varSheetA, 1) To UBound(varSheetA, 1)
        For iCol = LBound(varSheetA, 2) To UBound(varSheetA, 2)
            If varSheetA(iRow, iCol) = varSheetB(iRow, iCol) Then
                ' Cells are identical.
                ' Do nothing.
            Else
                ' Cells are different.
                ' Code goes here for whatever it is you want to do.
            End If
        Next iCol
    Next iRow

End Sub

To compare to a sheet in a different workbook, open that workbook and get the sheet as follows:

Set wbkA = Workbooks.Open(filename:="C:\MyBook.xls")
Set varSheetA = wbkA.Worksheets("Sheet1") ' or whatever sheet you need

Java doesn't have "true" multidimensional arrays.

For example, arr[i][j][k] is equivalent to ((arr[i])[j])[k]. In other words, arr is simply an array, of arrays, of arrays.

So, if you know how arrays work, you know how multidimensional arrays work!

Declaration:

int[][][] threeDimArr = new int[4][5][6];

or, with initialization:

int[][][] threeDimArr = { { { 1, 2 }, { 3, 4 } }, { { 5, 6 }, { 7, 8 } } };

Access:

int x = threeDimArr[1][0][1];

or

int[][] row = threeDimArr[1];

String representation:

Arrays.deepToString(threeDimArr);

yields

"[[[1, 2], [3, 4]], [[5, 6], [7, 8]]]"

Class instances often encapsulate control over resources that are not managed by the runtime, such as window handles (HWND), database connections, and so on. Therefore, you should provide both an explicit and an implicit way to free those resources. Provide implicit control by implementing the protected Finalize Method on an object (destructor syntax in C# and the Managed Extensions for C++). The garbage collector calls this method at some point after there are no longer any valid references to the object. In some cases, you might want to provide programmers using an object with the ability to explicitly release these external resources before the garbage collector frees the object. If an external resource is scarce or expensive, better performance can be achieved if the programmer explicitly releases resources when they are no longer being used. To provide explicit control, implement the Dispose method provided by the IDisposable Interface. The consumer of the object should call this method when it is done using the object. Dispose can be called even if other references to the object are alive.

Note that even when you provide explicit control by way of Dispose, you should provide implicit cleanup using the Finalize method. Finalize provides a backup to prevent resources from permanently leaking if the programmer fails to call Dispose.

Have you tried with the custom format "#,##0.##" ?

If you dont want to use $.browser, take a look at case 1, otherwise maybe case 2 and 3 can help you just to get informed because it is not recommended to use $.browser (the user agent can be spoofed using this). An alternative can be using jQuery.support that will detect feature support and not agent info.

But...

If you insist on getting browser type (just Chrome or Safari) but not using $.browser, case 1 is what you looking for...

This fits your requirement:

Case 1: (No jQuery and no $.browser, just javascript)

Live Demo: http://jsfiddle.net/oscarj24/DJ349/

var isChrome = /Chrome/.test(navigator.userAgent) && /Google Inc/.test(navigator.vendor);
var isSafari = /Safari/.test(navigator.userAgent) && /Apple Computer/.test(navigator.vendor);

if (isChrome) alert("You are using Chrome!");
if (isSafari) alert("You are using Safari!");

These cases I used in times before and worked well but they are not recommended...

Case 2: (Using jQuery and $.browser, this one is tricky)

Live Demo: http://jsfiddle.net/oscarj24/gNENk/

$(document).ready(function(){

    /* Get browser */
    $.browser.chrome = /chrome/.test(navigator.userAgent.toLowerCase());

    /* Detect Chrome */
    if($.browser.chrome){
        /* Do something for Chrome at this point */
        /* Finally, if it is Chrome then jQuery thinks it's 
           Safari so we have to tell it isn't */
        $.browser.safari = false;
    }

    /* Detect Safari */
    if($.browser.safari){
        /* Do something for Safari */
    }

});

Case 3: (Using jQuery and $.browser, "elegant" solution)

Live Demo: http://jsfiddle.net/oscarj24/uJuEU/

$.browser.chrome = $.browser.webkit && !!window.chrome;
$.browser.safari = $.browser.webkit && !window.chrome;

if ($.browser.chrome) alert("You are using Chrome!");
if ($.browser.safari) alert("You are using Safari!");

I don't think min/max validations attribute exist. I would use something like

[Range(1, Int32.MaxValue)]

for minimum value 1 and

[Range(Int32.MinValue, 10)]

for maximum value 10

use for each loop...

ArrayList<Character> al = new ArrayList<>();    
String input="hello";

for (int i = 0; i < input.length(); i++){
    al.add(input.charAt(i));
}

for (Character ch : al) {               
    System.Out.println(ch);             
}

Execute following commands step by step :

sudo npm uninstall -g angular-cli @angular/cli

sudo npm cache clean

npm install npm@latest -g

sudo npm install -g @angular/cli

npm rebuild node-sass --force

Referencing Bash Variables Requires Parameter Expansion

The default shell on most Linux distributions is Bash. In Bash, variables must use a dollar sign prefix for parameter expansion. For example:

x=20
y=5
expr $x / $y

Of course, Bash also has arithmetic operators and a special arithmetic expansion syntax, so there's no need to invoke the expr binary as a separate process. You can let the shell do all the work like this:

x=20; y=5
echo $((x / y))

Apache Commons Lang 3.0+ has a few Pair classes: http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/tuple/package-summary.html

If you use PyCharm, please change you 'Project Interpreter' to '2.7.x'

I claim no credit for the answer because I found it after some searching:

What I didn't know is that PostgreSQL allows you to define your own aggregate functions with CREATE AGGREGATE

This post on the PostgreSQL list shows how trivial it is to create a function to do what's required:

CREATE AGGREGATE textcat_all(
  basetype    = text,
  sfunc       = textcat,
  stype       = text,
  initcond    = ''
);

SELECT company_id, textcat_all(employee || ', ')
FROM mytable
GROUP BY company_id;

Try this in your console:

javac {$PathToYourProyect}/*

If you also need any external library, try:

javac -cp {$PathToYourLibrary}.jar {$PathToYourProyect}/*

((portion/total) * 100).toFixed(2) + '%'

You will have the duplicate values for name and price here. And ids are duplicate in the drinks_photos table.There is no way you can avoid them.Also what exactly you want the output ?

this.donorsTableAdapter.Fill(this.sbmsDataSet.donors);

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

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

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

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

Every time setColor gets hit, you are setting count = 1. You would need to define count outside of the scope of the function. Example:

var count=1;
function setColor(btn, color){
    var property = document.getElementById(btn);
    if (count == 0){
        property.style.backgroundColor = "#FFFFFF"
        count=1;        
    }
    else{
        property.style.backgroundColor = "#7FFF00"
        count=0;
    }

}

Try this command:

cat /proc/stat

This will be something like this:

Passphrases can be added to an existing key or changed without regenerating the key pair:
Note This will work if keys doesn't had a passphrase, otherwise you'll get this: Enter old passphrase: then Bad passphrase

$ ssh-keygen -p
Enter file in which the key is (/Users/tekkub/.ssh/id_rsa):
Key has comment '/Users/tekkub/.ssh/id_rsa'
Enter new passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved with the new passphrase.

If your key had passphrase then, There's no way to recover the passphrase for a pair of SSH keys. In that case you have to create a new pair of SSH keys.

W3Schools have a nice article on this subject.

Scripts in <head>

Scripts to be executed when they are called, or when an event is triggered, are placed in functions.

Put your functions in the head section, this way they are all in one place, and they do not interfere with page content.

Scripts in <body>

If you don't want your script to be placed inside a function, or if your script should write page content, it should be placed in the body section.

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

  width: 70px;_x000D_

I haven't worked much with Appcelerator Titanium, but I'll put my understanding of it at the end.

I can speak a bit more to the differences between PhoneGap and Xamarin, as I work with these two 5 (or more) days a week.

If you are already familiar with C# and JavaScript, then the question I guess is, does the business logic lie in an area more suited to JavaScript or C#?

PhoneGap

PhoneGap is designed to allow you to write your applications using JavaScript and HTML, and much of the functionality that they do provide is designed to mimic the current proposed specifications for the functionality that will eventually be available with HTML5. The big benefit of PhoneGap in my opinion is that since you are doing the UI with HTML, it can easily be ported between platforms. The downside is, because you are porting the same UI between platforms, it won't feel quite as at home in any of them. Meaning that, without further tweaking, you can't have an application that feels fully at home in iOS and Android, meaning that it has the iOS and Android styling. The majority of your logic can be written using JavaScript, which means it too can be ported between platforms. If the current PhoneGap API does most of what you want, then it's pretty easy to get up and running. If however, there are things you need from the device that are not in the API, then you get into the fun of Plugin Development, which will be in the native device's development language of choice (with one caveat, but I'll get to that), which means you would likely need to get up to speed quickly in Objective-C, Java, etc. The good thing about this model, is you can usually adapt many different native libraries to serve your purpose, and many libraries already have PhoneGap Plugins. Although you might not have much experience with these languages, there will at least be a plethora of examples to work from.

Xamarin

Xamarin.iOS and Xamarin.Android (also known as MonoTouch and MonoDroid), are designed to allow you to have one library of business logic, and use this within your application, and hook it into your UI. Because it's based on .NET 4.5, you get some awesome lambda notations, LINQ, and a whole bunch of other C# awesomeness, which can make writing your business logic less painful. The downside here is that Xamarin expects that you want to make your applications truly feel native on the device, which means that you will likely end up rewriting your UI for each platform, before hooking it together with the business logic. I have heard about MvvmCross, which is designed to make this easier for you, but I haven't really had an opportunity to look into it yet. If you are familiar with the MVVM system in C#, you may want to have a look at this. When it comes to native libraries, MonoTouch becomes interesting. MonoTouch requires a Binding library to tell your C# code how to link into the underlying Objective-C and Java code. Some of these libraries will already have bindings, but if yours doesn't, creating one can be, interesting. Xamarin has made a tool called Objective Sharpie to help with this process, and for the most part, it will get you 95% of the way there. The remaining 5% will probably take 80% of your time attempting to bind a library.

Update

As noted in the comments below, Xamarin has released Xamarin Forms which is a cross platform abstraction around the platform specific UI components. Definitely worth the look.

PhoneGap / Xamarin Hybrid

Now because I said I would get to it, the caveat mentioned in PhoneGap above, is a Hybrid approach, where you can use PhoneGap for part, and Xamarin for part. I have quite a bit of experience with this, and I would caution you against it. Highly. The problem with this, is it is such a no mans' land that if you ever run into issues, almost no one will have come close to what you're doing, and will question what you're trying to do greatly. It is doable, but it's definitely not fun.

Appcelerator Titanium

As I mentioned before, I haven't worked much with Appcelerator Titanium, So for the differences between them, I will suggest you look at Comparing Titanium and Phonegap or Comparison between Corona, Phonegap, Titanium as it has a very thorough description of the differences. Basically, it appears that though they both use JavaScript, how that JavaScript is interpreted is slightly different. With Titanium, you will be writing your JavaScript to the Titanium SDK, whereas with PhoneGap, you will write your application using the PhoneGap API. As PhoneGap is very HTML5 and JavaScript standards compliant, you can use pretty much any JavaScript libraries you want, such as JQuery. With PhoneGap your user interface will be composed of HTML and CSS. With Titanium, you will benefit from their Cross-platform XML which appears to generate Native components. This means it will definitely have a better native look and feel.

For me I had to put the whole interval in single quotes not just the value of the interval.

select id,  
   title,
   created_at + interval '1 day' * claim_window as deadline from projects   

Instead of

select id,  
   title,
   created_at + interval '1' day * claim_window as deadline from projects   

Postgres Date/Time Functions

Chrome's Javascript console suggested I declare the entire page address in my HTTP referrer list, in this instance http://mywebsite.com/map.htm Even though the exact address is http://www.mywebsite.com/map.htm - I already had wildcard styles listed as suggested by others but this was the only way it would work for me.

While the answers in the thread are all true enough, I cannot resist the urge to tell you that it in fact is possible to have an anonymous class implement an interface, even though it takes a bit of creative cheating to get there.

Back in 2008 I was writing a custom LINQ provider for my then employer, and at one point I needed to be able to tell "my" anonymous classes from other anonymous ones, which meant having them implement an interface that I could use to type check them. The way we solved it was by using aspects (we used PostSharp), to add the interface implementation directly in the IL. So, in fact, letting anonymous classes implement interfaces is doable, you just need to bend the rules slightly to get there.

Yes, you either need to do this onload or in a <script> tag after the closing </body> tag, when the lc element is already found in the document's DOM tree.

I had a similar problem. In my case, the version of testng in my .m2/repositories folder was corrupt, but when I deleted it & did a maven update again, everything worked fine.

You can do socket = undefined in erase which socket you have connected. So when want to connected do socket(url)

So it will look like this

const socketClient = require('socket.io-client');

let socket;

// Connect to server
socket = socketClient(url)

// When want to disconnect
socket = undefined;

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

I'm working on a Yocto Linux system that has a limited set of available Linux tools. I wanted to kill the process that was using a particular port (1883).

First, to see what ports we are listening to I used the following command:

root@root:~# netstat -lt
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 0.0.0.0:hostmon         0.0.0.0:*               LISTEN      
tcp        0      0 localhost.localdomain:domain 0.0.0.0:*               LISTEN

tcp        0      0 0.0.0.0:1883            0.0.0.0:*               LISTEN      
tcp        0      0 :::hostmon              :::*                    LISTEN

Next, I found the name of the process using port 1883 in the following way:

root@root:~# fuser 1883/tcp
290 
root@root:~# ps | grep 290
  290 mosquitt 25508 S    /usr/sbin/mosquitto -c /etc/mosquitto/mosquitto.conf
12141 root      8444 S    grep 290

As we can see above, it's the program /usr/sbin/mosquitto that's using port 1883.

Lastly, I killed the process:

root@root:~# systemctl stop mosquitto

I used systemctl becuase in this case it was a systemd service.

The problem is that '_' underscores are not valid in header attribute. If removing the underscore is not an option you can add to the server block:

underscores_in_headers on;

This is basically a copy and paste from @kishorer747 comment on @Fleshgrinder answer, and solution is from: https://serverfault.com/questions/586970/nginx-is-not-forwarding-a-header-value-when-using-proxy-pass/586997#586997

I added it here as in my case the application behind nginx was working perfectly fine, but as soon ngix was between my flask app and the client, my flask app would not see the headers any longer. It was kind of time consuming to debug.

You can also pad the characters left by including a number following the X, such as this: string.format("0x{0:X8}", string_to_modify), which yields "0x00000C20".

When I added the proxy info to the %JAVA_OPTS%, I got an error "-Dhttp.proxyHost=yourserver was unexpected at this time". I put the proxy info in %SBT_OPTS% and it worked.

The error you get if because you need to escape the quotes (like other answers said).

To avoid that, you can use an alternative syntax for you strings declarations, called "Heredoc"

With this syntax, you can declare a long string, even containing single-quotes and/or double-quotes, whithout having to escape thoses ; it will make your Javascript code easier to write, modify, and understand -- which is always a good thing.

As an example, your code could become :

$str = <<<MY_MARKER
<script type="text/javascript">
  document.write("Hello World!");
</script>
MY_MARKER;

echo $str;

Note that with Heredoc syntax (as with string delimited by double-quotes), variables are interpolated.

Seems odd to be inserting a value into an automatically incrementing field.

Also, have you tried the insert() method instead of execSQL?

ContentValues insertValues = new ContentValues();
insertValues.put("Description", "Electricity");
insertValues.put("Amount", 500);
insertValues.put("Trans", 1);
insertValues.put("EntryDate", "04/06/2011");
db.insert("CashData", null, insertValues);

Based in @Daniel answer I did:

for remote in \`git branch | grep -v master\`
do 
    git push -u origin $remote
done

The app project you downloaded may include a signed info in the file of build.gradle. If you saw codes like these:

buildTypes {
    debug {
        signingConfig signingConfigs.release
    }
    release {
        signingConfig signingConfigs.release
    }
}

you could delete them and try again.

Here you go: ES5

var test = 'Hello World';
if( test.indexOf('World') >= 0){
  // Found world
}

With ES6 best way would be to use includes function to test if the string contains the looking work.

const test = 'Hello World';
if (test.includes('World')) { 
  // Found world
}

Aditya,

As you said in your last comment that you are trying to access chrome of some other system so based on that you should keep your chrome driver in that system itself.

for example: if you are trying to access linux chrome from windows then you need to put your chrome driver in linux at some place and give permission as 777 and use below code at your windows system.

System.setProperty("webdriver.chrome.driver", "\\var\\www\\Jar\\chromedriver");
Capability= DesiredCapabilities.chrome();   Capability.setPlatform(org.openqa.selenium.Platform.ANY);
browser=new RemoteWebDriver(new URL(nodeURL),Capability);

This is working code of my system.

Here you have the angularjs http request to the API that any client will have to do. Just adapt the WS url and params (if you have) to your case. It's a mixture between Naoe's answer and this one:

$http({
    url: '/path/to/your/API',
    method: 'POST',
    params: {},
    headers: {
        'Content-type': 'application/pdf',
    },
    responseType: 'arraybuffer'
}).success(function (data, status, headers, config) {
    // TODO when WS success
    var file = new Blob([data], {
        type: 'application/csv'
    });
    //trick to download store a file having its URL
    var fileURL = URL.createObjectURL(file);
    var a = document.createElement('a');
    a.href = fileURL;
    a.target = '_blank';
    a.download = 'yourfilename.pdf';
    document.body.appendChild(a); //create the link "a"
    a.click(); //click the link "a"
    document.body.removeChild(a); //remove the link "a"
}).error(function (data, status, headers, config) {
    //TODO when WS error
});

Explanation of the code:

1. Angularjs request a file.pdf at the URL: /path/to/your/API.
2. Success is received on the response
3. We execute a trick with JavaScript on the front-end:
   • Create an html link ta: <a>.
   • Click the hyperlink <a> tag, using the JS click() function
4. Remove the html <a> tag, after its click.

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

i don't know what mistakes i did while implementing the above solutions, bt they were unsuccessful for me

txtDeck.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override       
    public void onFocusChange(View v, boolean hasFocus) {
        txtDeck.setText("");
    }
});

This works for me,

I created a little library functionality to solve these problems:

Instead of:

public T DifficultCalculation<T>(T a, T b)
{
    T result = a * b + a; // <== WILL NOT COMPILE!
    return result;
}
Console.WriteLine(DifficultCalculation(2, 3)); // Should result in 8.

You could write:

public T DifficultCalculation<T>(Number<T> a, Number<T> b)
{
    Number<T> result = a * b + a;
    return (T)result;
}
Console.WriteLine(DifficultCalculation(2, 3)); // Results in 8.

You can find the source code here: https://codereview.stackexchange.com/questions/26022/improvement-requested-for-generic-calculator-and-generic-number

I just input some value that I knew was invalid and here is the output:

'whatToInput' is not a supported event for HtmlPanelGrid. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

So values you can pass to event are

• click
• dblclick
• keydown
• mousedown
• mousemove
• mouseover
• mouseup

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

While @jackofallcode answer is correct, it can be written in one line:

((RelativeLayout.LayoutParams) viewToLayout.getLayoutParams()).addRule(RelativeLayout.BELOW, R.id.below_id);

Before you lose more time solving the problem, like me, try just to restart your windows machine. Worked for me after applying all the other solutions.

Though I found Gabriel answer to work to a degree i did find the following when trying to order the list vertically (first ul A-D and second ul E-G):

• When the ul had an even number of li's in it, it was not evenly spreading it across the ul's
• using the data-column in the ul didn't seem to work very well, I had to put 4 for 3 columns and even then it was still only spreading the li's into 2 of the ul generated by the JS

I have revised the JQuery so the above hopefully doesn't happen.

(function ($) {
    var initialContainer = $('.customcolumns'),
        columnItems = $('.customcolumns li'),
        columns = null,
        column = 0;
    function updateColumns() {
        column = 0;
        columnItems.each(function (idx, el) {
            if ($(columns.get(column)).find('li').length >= (columnItems.length / initialContainer.data('columns'))) {
                column += 1;
            }
            $(columns.get(column)).append(el);
        });
    }
    function setupColumns() {
        columnItems.detach();
        while (column++ < initialContainer.data('columns')) {
            initialContainer.clone().insertBefore(initialContainer);
            column++;
        }
        columns = $('.customcolumns');
        updateColumns();
    }

    $(setupColumns);
})(jQuery);

.customcolumns {
  float: left;
  position: relative;
  margin-right: 20px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
  <ul class="customcolumns" data-columns="3">
    <li>A</li>
    <li>B</li>
    <li>C</li>
    <li>D</li>
    <li>E</li>
    <li>F</li>
    <li>G</li>
    <li>H</li>
    <li>I</li>
    <li>J</li>
    <li>K</li>

I know its a bit late now, but you could do something such as this:

function AddToArray ($post_information) {
    //Create the return array
    $return = array();
    //Iterate through the array passed
    foreach ($post_information as $key => $value) {
        //Append the key and value to the array, e.g.
            //$_POST['keys'] = "values" would be in the array as "keys"=>"values"
        $return[$key] = $value;
    }
    //Return the created array
    return $return;
}

The test with:

if (isset($_POST['submit'])) {
    var_dump(AddToArray($_POST));
}

This for me produced:

array (size=1)
  0 => 
    array (size=5)
      'stake' => string '0' (length=1)
      'odds' => string '' (length=0)
      'ew' => string 'false' (length=5)
      'ew_deduction' => string '' (length=0)
      'submit' => string 'Open' (length=4)

also for array you can use short annotattion:

$arr = [
    [
        "region" => "valore",
        "price" => "valore2"
    ],
    [
        "region" => "valore",
        "price" => "valore2"
    ],
    [
        "region" => "valore",
        "price" => "valore2"
    ]
];

echo json_encode($arr);

Try this:

string callbackurl = Request.Url.Host != "localhost" 
    ? Request.Url.Host : Request.Url.Authority;

This will work for local as well as production environment. Because the local uses url with port no that is possible using Url.Host.

You wrote:

var divNode = document.createElement("div");
divNode.innerHTML = "<br><style>h1 { background: red; }</style>";
document.body.appendChild(divNode);

Why not this?

var styleNode = document.createElement("style");
document.head.appendChild(styleNode);

Henceforward you can append CSS rules easily to the HTML code:

styleNode.innerHTML = "h1 { background: red; }\n";
styleNode.innerHTML += "h2 { background: green; }\n";

...or directly to the DOM:

styleNode.sheet.insertRule("h1 { background: red; }");
styleNode.sheet.insertRule("h2 { background: green; }");

I expect this to work everywhere except archaic browsers.

Definitely works in Chrome in year 2019.

With REGEXP_SUBSTR is as simple as:

SELECT REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 1) col_one,
       REGEXP_SUBSTR(t.column_one, '[^ ]+', 1, 2) col_two
FROM YOUR_TABLE t;

As already stated, you have too many methods (more than 65k) in your project and libs.

Prevent the Problem: Reduce the number of methods with Play Services 6.5+ and support-v4 24.2+

Since often the Google Play services is one of the main suspects in "wasting" methods with its 20k+ methods. Google Play services version 6.5 or later, it is possible for you to include Google Play services in your application using a number of smaller client libraries. For example, if you only need GCM and maps you can choose to use these dependencies only:

dependencies {
    compile 'com.google.android.gms:play-services-base:6.5.+'
    compile 'com.google.android.gms:play-services-maps:6.5.+'
}

The full list of sub libraries and it's responsibilities can be found in the official google doc.

Update: Since Support Library v4 v24.2.0 it was split up into the following modules:

support-compat, support-core-utils, support-core-ui, support-media-compat and support-fragment

dependencies {
    compile 'com.android.support:support-fragment:24.2.+'
}

Do note however, if you use support-fragment, it will have dependencies to all the other modules (ie. if you use android.support.v4.app.Fragment there is no benefit)

See here the official release notes for support-v4 lib

Enable MultiDexing

Since Lollipop (aka build tools 21+) it is very easy to handle. The approach is to work around the 65k methods per dex file problem to create multiple dex files for your app. Add the following to your gradle build file (this is taken from the official google doc on applications with more than 65k methods):

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.0"

    defaultConfig {
        ...
        // Enabling multidex support.
        multiDexEnabled true
    }
    ...
}

dependencies {
  compile 'com.android.support:multidex:1.0.1'
}

The second step is to either prepare your Application class or if you don't extend Application use the MultiDexApplication in your Android Manifest:

Either add this to your Application.java

@Override
  protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
  }

or use the provided application from the mutlidex lib

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.android.myapplication">
    <application
        ...
        android:name="android.support.multidex.MultiDexApplication">
        ...
    </application>
</manifest>

Prevent OutOfMemory with MultiDex

As further tip, if you run into OutOfMemory exceptions during the build phase you could enlarge the heap with

android {
    ...
    dexOptions {
        javaMaxHeapSize "4g"
    }
}

which would set the heap to 4 gigabytes.

See this question for more detail on the dex heap memory issue.

Analyze the source of the Problem

To analyze the source of the methods the gradle plugin https://github.com/KeepSafe/dexcount-gradle-plugin can help in combination with the dependency tree provided by gradle with e.g.

.\gradlew app:dependencies

See this answer and question for more information on method count in android

Example 2 on w3schools shows what you are trying to achieve.

<?php
header("Content-type:application/pdf");

// It will be called downloaded.pdf
header("Content-Disposition:attachment;filename='downloaded.pdf'");

// The PDF source is in original.pdf
readfile("original.pdf");
?>

Also remember that,

It is important to notice that header() must be called before any actual output is sent (In PHP 4 and later, you can use output buffering to solve this problem)

From the MySql site.

Starting with version 6.7, Connector/Net will no longer include the MySQL for Visual Studio integration. That functionality is now available in a separate product called MySQL for Visual Studio available using the MySQL Installer for Windows (see http://dev.mysql.com/tech-resources/articles/mysql-installer-for-windows.html).

have a look at example 3 from http://www.php.net/manual/en/language.oop5.basic.php

$className = 'Foo';
$instance = new $className(); // Foo()

IF you happen to have ODBC set up, you can get the password from the ODBC config file. This is in /etc/odbc.ini for Linux and in the Software/ODBC folder in the registry in Windows (there are several - it may take some hunting)

I don't believe the JavaScript solutions work anymore. I was doing it from within my notebook with:

    from IPython.display import display, HTML
    js = ('<script>function ConnectButton(){ '
           'console.log("Connect pushed"); '
           'document.querySelector("#connect").click()} '
           'setInterval(ConnectButton,3000);</script>')
    display(HTML(js))

When you first do a Run all (before the JavaScript or Python code has started), the console displays:

Connected to 
wss://colab.research.google.com/api/kernels/0e1ce105-0127-4758-90e48cf801ce01a3/channels?session_id=5d8...

However, ever time the JavaScript runs, you see the console.log portion, but the click portion simply gives:

Connect pushed

Uncaught TypeError: Cannot read property 'click' of null
 at ConnectButton (<anonymous>:1:92)

Others suggested the button name has changed to #colab-connect-button, but that gives same error.

After the runtime is started, the button is changed to show RAM/DISK, and a drop down is presented. Clicking on the drop down creates a new <DIV class=goog menu...> that was not shown in the DOM previously, with 2 options "Connect to hosted runtime" and "Connect to local runtime". If the console window is open and showing elements, you can see this DIV appear when you click the dropdown element. Simply moving the mouse focus between the two options in the new window that appears adds additional elements to the DOM, as soon as the mouse looses focus, they are removed from the DOM completely, even without clicking.

When running a single test I usually do:

go test -run TestSomethingReallyCool ./folder1/folder2/ -v -count 1

-count 1 also ensures that the test is ran every time instead of being cached. Useful when you are testing against race conditions and have a test that fails only sometimes. In Go versions not using modules the same could be achieved by setting GOCACHE=off but this interacts poorly with Go modules.

In another way you can use window.location.href="your URL"

e.g.:

res.send('<script>window.location.href="your URL";</script>');

or:

return res.redirect("your url");

Using pytz

from datetime import datetime
from pytz import timezone

fmt = "%Y-%m-%d %H:%M:%S %Z%z"
timezonelist = ['UTC','US/Pacific','Europe/Berlin']
for zone in timezonelist:

    now_time = datetime.now(timezone(zone))
    print now_time.strftime(fmt)

The statement def foo(client_id: str) -> list or bool: when evaluated is equivalent to def foo(client_id: str) -> list: and will therefore not do what you want.

The native way to describe a "either A or B" type hint is Union (thanks to Bhargav Rao):

def foo(client_id: str) -> Union[list, bool]:

I do not want to be the "Why do you want to do this anyway" guy, but maybe having 2 return types isn't what you want:

If you want to return a bool to indicate some type of special error-case, consider using Exceptions instead. If you want to return a bool as some special value, maybe an empty list would be a good representation. You can also indicate that None could be returned with Optional[list]

The following example validates an XML file and generates the appropriate error or warning.

using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;

public class Sample
{

    public static void Main()
    {
        //Load the XmlSchemaSet.
        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.Add("urn:bookstore-schema", "books.xsd");

        //Validate the file using the schema stored in the schema set.
        //Any elements belonging to the namespace "urn:cd-schema" generate
        //a warning because there is no schema matching that namespace.
        Validate("store.xml", schemaSet);
        Console.ReadLine();
    }

    private static void Validate(String filename, XmlSchemaSet schemaSet)
    {
        Console.WriteLine();
        Console.WriteLine("\r\nValidating XML file {0}...", filename.ToString());

        XmlSchema compiledSchema = null;

        foreach (XmlSchema schema in schemaSet.Schemas())
        {
            compiledSchema = schema;
        }

        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add(compiledSchema);
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
        settings.ValidationType = ValidationType.Schema;

        //Create the schema validating reader.
        XmlReader vreader = XmlReader.Create(filename, settings);

        while (vreader.Read()) { }

        //Close the reader.
        vreader.Close();
    }

    //Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

The preceding example uses the following input files.

<?xml version='1.0'?>

The dual example above which is in PL/SQL was great becuase I wanted to do something similar, but I wanted it client side...so here is the SQL I used to send a similar statement direct from some C#

MERGE INTO Employee USING dual ON ( "id"=2097153 )
WHEN MATCHED THEN UPDATE SET "last"="smith" , "name"="john"
WHEN NOT MATCHED THEN INSERT ("id","last","name") 
    VALUES ( 2097153,"smith", "john" )

However from a C# perspective this provide to be slower than doing the update and seeing if the rows affected was 0 and doing the insert if it was.

Here i show you a snippet where your problem is solved (i know, it's been too long since you posted it, but i think this is cleaner than de "clear" fix)

Use Blazor http://learn-blazor.com/architecture/interop/

Here's the C#:

namespace BlazorDemo.Client
{
   public static class MyCSharpFunctions
   {
       public static void CsharpFunction()
       {
          // Notification.show();
       }
   }
}

Then the Javascript:

const CsharpFunction = Blazor.platform.findMethod(
"BlazorDemo.Client",
"BlazorDemo.Client",
"MyCSharpFunctions",
"CsharpFunction"
);
if (Javascriptcondition > 0) {
   Blazor.platform.callMethod(CsharpFunction, null)
}

In the VS Output pane (switched to the Test view), there was this error:

Could not load file or assembly 'XXX.UnitTest, Version=9.4.0.0, Culture=neutral, PublicKeyToken=14345dd3754e3918' or one of its dependencies. Strong name validation failed. (Exception from HRESULT: 0x8013141A)

In the project settings for the test project, under the Signing tab, someone had checked 'Sign the assembly'. Unchecking that and building caused the tests to show up.

A colleague also solved the same issue by adding keys from this post to the registry:

https://blogs.msdn.microsoft.com/keithmg/2012/03/20/strong-name-validation-failed-exception-from-hresult-0x8013141a/

rbind() needs the two object names to be the same. For example, the first object names: ID Age, the next object names: ID Gender,if you want to use rbind(), it will print out:

names do not match previous names

Using sudo is not recommended. It may give you permission issue later. While the above works, I am not a fan of changing folders owned by root to be writable for users, although it may only be an issue with multiple users. To work around that, you could use a group, with 'npm users' but that is also more administrative overhead. See here for the options to deal with permissions from the documentation: https://docs.npmjs.com/getting-started/fixing-npm-permissions

I would go for option 2:

To minimize the chance of permissions errors, you can configure npm to use a different directory. In this example, it will be a hidden directory on your home folder.

Make a directory for global installations:

 mkdir ~/.npm-global

Configure npm to use the new directory path:

 npm config set prefix '~/.npm-global'

Open or create a ~/.profile file and add this line:

 export PATH=~/.npm-global/bin:$PATH

Back on the command line, update your system variables:

 source ~/.profile

Test: Download a package globally without using sudo.

npm install -g jshint

If still show permission error run (mac os):

sudo chown -R $USER ~/.npm-global   

This works with the default ubuntu install of:

sudo apt-get install nodejs npm

I recommend nvm if you want more flexibility in managing versions: https://github.com/creationix/nvm

On MacOS use brew, it should work without sudo out of the box if you're on a recent npm version. Enjoy :)

BigDecimal a = new BigDecimal("12345.0789");
a = a.divide(new BigDecimal("1"), 2, BigDecimal.ROUND_HALF_UP);
//Also check other rounding modes
System.out.println("a >> "+a.toPlainString()); //Returns 12345.08

Add necessary namespace

using System.Linq;

Then you can use linq Contains() method

string[] printer = {"jupiter", "neptune", "pangea", "mercury", "sonic"};
if(printer.Contains("jupiter"))
{
    Process.Start("BLAH BLAH CODE TO ADD PRINTER VIA WINDOWS EXEC"");
}

Just wanted to add another simple way someone can sort the the WPF ListView

void SortListView(ListView listView)
{
    IEnumerable listView_items = listView.Items.SourceCollection;
    List<MY_ITEM_CLASS> listView_items_to_list = listView_items.Cast<MY_ITEM_CLASS>().ToList();

    Comparer<MY_ITEM_CLASS> scoreComparer = Comparer<MY_ITEM_CLASS>.Create((first, second) => first.COLUMN_NAME.CompareTo(second.COLUMN_NAME));

    listView_items_to_list.Sort(scoreComparer);
    listView.ItemsSource = null;
    listView.Items.Clear();
    listView.ItemsSource = listView_items_to_list;
}

In my case, the error occurred when I made python manage.py makemigrations on Django 2.0.6.

The solution was to run python manage.py runserver and see the actual error (which was just a missing environment variable).

usually when i work with remote location teams it is important for me that i have prior knowledge what change done by other teams in same file, before i follow git stages untrack-->staged-->commit for that i wrote an bash script which help me to avoid unnecessary resolve merge conflict with remote team or make new local branch and compare and merge on main branch

#set -x 
branchname=`git branch | grep -F '*' |  awk '{print $2}'`
echo $branchname
git fetch origin ${branchname}
for file in `git status | grep "modified" | awk "{print $2}" `
do
echo "PLEASE CHECK OUT GIT DIFF FOR "$file 
git difftool FETCH_HEAD $file ;
done

in above script i fetch remote main branch (not necessary its master branch)to FETCH_HEAD them make a list of my modified file only and compare modified files to git difftool

here many difftool supported by git, i configure 'Meld Diff Viewer' for good GUI comparison .

you can do like this :

<?php
    $file = 'your_images.jpg';

    header('Content-Type: image/jpeg');
    header('Content-Length: ' . filesize($file));
    echo file_get_contents($file);
?>

Perhaps replace is what you are looking for:

> x = c(3, 2, 1, 0, 4, 0)
> replace(x, x==0, 1)
[1] 3 2 1 1 4 1

Or, if you don't have x (any specific reason why not?):

replace(c(3, 2, 1, 0, 4, 0), c(3, 2, 1, 0, 4, 0)==0, 1)

Many people are familiar with gsub, so you can also try either of the following:

as.numeric(gsub(0, 1, x))
as.numeric(gsub(0, 1, c(3, 2, 1, 0, 4, 0)))

Update

After reading the comments, perhaps with is an option:

with(data.frame(x = c(3, 2, 1, 0, 4, 0)), replace(x, x == 0, 1))

You can use the reload method of the $route service. Inject $route in your controller and then create a method reloadRoute on your $scope.

$scope.reloadRoute = function() {
   $route.reload();
}

Then you can use it on the link like this:

<a ng-click="reloadRoute()" class="navbar-brand" title="home"  data-translate>PORTAL_NAME</a>

This method will cause the current route to reload. If you however want to perform a full refresh, you could inject $window and use that:

$scope.reloadRoute = function() {
   $window.location.reload();
}

Later edit (ui-router):

As mentioned by JamesEddyEdwards and Dunc in their answers, if you are using angular-ui/ui-router you can use the following method to reload the current state / route. Just inject $state instead of $route and then you have:

$scope.reloadRoute = function() {
    $state.reload();
};

I also had the same problem. I figured out that the HAXM hardware accelerator was recently updated but not reinstalled since the update manager just updates the installer package which get saved to your hard drive. You will need to remove HAXM and then run that installer package to complete the update. Usualy this gets installed into ANDROID-SDK-ROOT\android-sdk\extras\intel\Hardware_Accelerated_Execution_Manager. Where ANDROID-SDK-ROOT is the location where your android sdk is located.

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

There is a lot of confusion about IdentityDbContext, a quick search in Stackoverflow and you'll find these questions:
" Why is Asp.Net Identity IdentityDbContext a Black-Box?
How can I change the table names when using Visual Studio 2013 AspNet Identity?
Merge MyDbContext with IdentityDbContext"

To answer to all of these questions we need to understand that IdentityDbContext is just a class inherited from DbContext.

Based on the source code if we want to merge IdentityDbContext with our DbContext we have two options:

First Option:
Create a DbContext which inherits from IdentityDbContext and have access to the classes.

   public class ApplicationDbContext 
    : IdentityDbContext
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

Extra Notes:

1) We can also change asp.net Identity default table names with the following solution:

    public class ApplicationDbContext : IdentityDbContext
    {    
        public ApplicationDbContext(): base("DefaultConnection")
        {
        }

        protected override void OnModelCreating(System.Data.Entity.DbModelBuilder modelBuilder)
        {
            base.OnModelCreating(modelBuilder);
            modelBuilder.Entity<IdentityUser>().ToTable("user");
            modelBuilder.Entity<ApplicationUser>().ToTable("user");

            modelBuilder.Entity<IdentityRole>().ToTable("role");
            modelBuilder.Entity<IdentityUserRole>().ToTable("userrole");
            modelBuilder.Entity<IdentityUserClaim>().ToTable("userclaim");
            modelBuilder.Entity<IdentityUserLogin>().ToTable("userlogin");
        }
    }

2) Furthermore we can extend each class and add any property to classes like 'IdentityUser', 'IdentityRole', ...

    public class ApplicationRole : IdentityRole<string, ApplicationUserRole>
{
    public ApplicationRole() 
    {
        this.Id = Guid.NewGuid().ToString();
    }

    public ApplicationRole(string name)
        : this()
    {
        this.Name = name;
    }

    // Add any custom Role properties/code here
}


// Must be expressed in terms of our custom types:
public class ApplicationDbContext 
    : IdentityDbContext<ApplicationUser, ApplicationRole, 
    string, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    static ApplicationDbContext()
    {
        Database.SetInitializer<ApplicationDbContext>(new ApplicationDbInitializer());
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }

    // Add additional items here as needed
}

To save time we can use AspNet Identity 2.0 Extensible Project Template to extend all the classes.

Second Option:(Not recommended)
We actually don't have to inherit from IdentityDbContext if we write all the code ourselves.
So basically we can just inherit from DbContext and implement our customized version of "OnModelCreating(ModelBuilder builder)" from the IdentityDbContext source code

This exception is thrown if the underlying method(method called using Reflection) throws an exception.

So if the method, that has been invoked by reflection API, throws an exception (as for example runtime exception), the reflection API will wrap the exception into an InvocationTargetException.

No, there is no better way.

Actually you have an error in your pattern. What you want is:

DecimalFormat df = new DecimalFormat("#.00"); 

Note the "00", meaning exactly two decimal places.

If you use "#.##" (# means "optional" digit), it will drop trailing zeroes - ie new DecimalFormat("#.##").format(3.0d); prints just "3", not "3.00".

Your TextView Attributes need to be something like,

<TextView ... 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical|right" ../>

Now, Description why these need to be done,

 android:layout_width="match_parent"
 android:layout_height="match_parent"

Makes your TextView to match_parent or fill_parent if You don't want to be it like, match_parent you have to give some specified values to layout_height so it get space for vertical center gravity. android:layout_width="match_parent" necessary because it align your TextView in Right side so you can recognize respect to Parent Layout of TextView.

Now, its about android:gravity which makes the content of Your TextView alignment. android:layout_gravity makes alignment of TextView respected to its Parent Layout.

Update:

As below comment says use fill_parent instead of match_parent. (Problem in some device.)

In C, static means the function or variable you define can be only used in this file(i.e. the compile unit)

So, static inline means the inline function which can be used in this file only.

EDIT:

The compile unit should be The Translation Unit

There are no buts about it! Who want to grasp the subject must do the following ones,

• Peruse The Lost Art of Structure Packing written by Eric S. Raymond
• Glance at Eric's code example
• Last but not least, don't forget the following rule about padding that a struct is aligned to the largest type’s alignment requirements.

You can do it programmatically:

#include <unistd.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <stdlib.h>

int main() {
    int fd = creat("/tmp/foo.txt", 0644);
    ftruncate(fd, SIZE_IN_BYTES);
    close(fd);
    return 0;
}

This approach is especially useful to subsequently mmap the file into memory.

use the following command to check that the file has the correct size:

# du -B1 --apparent-size /tmp/foo.txt

Be careful:

# du /tmp/foo.txt

will probably print 0 because it is allocated as Sparse file if supported by your filesystem.

see also: man 2 open and man 2 truncate

You can use has

public boolean has(String key)

Determine if the JSONObject contains a specific key.

Example

JSONObject JsonObj = new JSONObject(Your_API_STRING); //JSONObject is an unordered collection of name/value pairs

if (JsonObj.has("address")) { 
    //Checking address Key Present or not
    String get_address = JsonObj .getString("address"); // Present Key
}
else {
    //Do Your Staff
}

SELECT Datediff(day,
(Convert(DateTime,Convert(varchar(2),Month(getdate()))+'/01/'+Convert(varchar(4),Year(getdate())))),
(Convert(DateTime,Convert(varchar(2),Month(getdate())+1)+'/01/'+Convert(varchar(4),Year(getdate()))))) as [No.of Days in a Month]

Here's a link to marketplace for extension. Extension "compareit" helps to compare two files wich you can choose from your current project and other directory on your computer or clipboard.

Anyway, I was following my workflow on a recent branch, and when I tried to merge it back to master, it all went to hell. There were tons of conflicts with things that should have not mattered. The conflicts just made no sense to me. It took me a day to sort everything out, and eventually culminated in a forced push to the remote master, since my local master has all conflicts resolved, but the remote one still wasn't happy.

In neither your partner's nor your suggested workflows should you have come across conflicts that didn't make sense. Even if you had, if you are following the suggested workflows then after resolution a 'forced' push should not be required. It suggests that you haven't actually merged the branch to which you were pushing, but have had to push a branch that wasn't a descendent of the remote tip.

I think you need to look carefully at what happened. Could someone else have (deliberately or not) rewound the remote master branch between your creation of the local branch and the point at which you attempted to merge it back into the local branch?

Compared to many other version control systems I've found that using Git involves less fighting the tool and allows you to get to work on the problems that are fundamental to your source streams. Git doesn't perform magic, so conflicting changes cause conflicts, but it should make it easy to do the write thing by its tracking of commit parentage.

I prefer to turn the tibble to data.frame. It shows everything and you're done

df %>% data.frame 

Something like this:

JSONObject songs= json.getJSONObject("songs");
Iterator x = songs.keys();
JSONArray jsonArray = new JSONArray();

while (x.hasNext()){
    String key = (String) x.next();
    jsonArray.put(songs.get(key));
}

I needed to do (the solution in the accepted answer):

git fetch origin
git reset --hard origin/master

Followed by:

git clean -f

to remove local files

To see what files will be removed (without actually removing them):

git clean -n -f

You can't use transparency on background-images directly, but you can achieve this effect with something like this:

http://jsfiddle.net/m4TgL/

HTML:

<div class="container">
    <div class="content">//my blog post</div>
</div>?

CSS:

.container {  position: relative; }

.container:before {
    content: "";
    position: absolute;
    top: 0;
    bottom: 0;
    left: 0;
    right: 0;
    z-index: 1;
    background-image: url('image.jpg');
   opacity: 0.5;
}

.content {
    position: relative; 
    z-index: 2;
}?

I have tried using the dependency without version tag and its worked fine for me.

Using str.format:

>>> array_alpha = [ 133, 53, 234, 241 ]
>>> print ''.join('{:02x}'.format(x) for x in array_alpha)
8535eaf1

or using format

>>> print ''.join(format(x, '02x') for x in array_alpha)
8535eaf1

Note: In the format statements, the 02 means it will pad with up to 2 leading 0s if necessary. This is important since [0x1, 0x1, 0x1] i.e. (0x010101) would be formatted to "111" instead of "010101"

or using bytearray with binascii.hexlify:

>>> import binascii
>>> binascii.hexlify(bytearray(array_alpha))
'8535eaf1'

Here is a benchmark of above methods in Python 3.6.1:

from timeit import timeit
import binascii

number = 10000

def using_str_format() -> str:
    return "".join("{:02x}".format(x) for x in test_obj)

def using_format() -> str:
    return "".join(format(x, "02x") for x in test_obj)

Using binascii.hexlify -> 0.014114164661833684

Methods using format do provide additional formatting options, as example separating numbers with spaces " ".join, commas ", ".join, upper-case printing "{:02X}".format(x)/format(x, "02X"), etc., but at a cost of great performance impact.

In your controller add the following:

@RequestParam(value = "_csrf", required = false) String csrf

And on jsp page add

<form:form modelAttribute="someName" action="someURI?${_csrf.parameterName}=${_csrf.token}

You can emulate any other data structure with a hashmap, so that's not a terrible limitation. Scanning from the top to the bottom, you create a hashmap for each row of the database, with an entry for each column. Add each of these hashmaps to a "master" hashmap, keyed on the id. If any node has a "parent" that you haven't seen yet, create an placeholder entry for it in the master hashmap, and fill it in when you see the actual node.

To print it out, do a simple depth-first pass through the data, keeping track of indent level along the way. You can make this easier by keeping a "children" entry for each row, and populating it as you scan the data.

As for whether there's a "better" way to store a tree in a database, that depends on how you're going to use the data. I've seen systems that had a known maximum depth that used a different table for each level in the hierarchy. That makes a lot of sense if the levels in the tree aren't quite equivalent after all (top level categories being different than the leaves).

you can using fxFlex from "@angular/flex-layout" in th and td like this:

<ng-container matColumnDef="value">
      <th mat-header-cell fxFlex="15%" *matHeaderCellDef>Value</th>
            <td mat-cell *matCellDef="let element" fxFlex="15%" fxLayoutAlign="start center">
                           {{'value'}}
            </td>
       </th>
</ng-container>

Given an object which I suspect to be some kind of IList<>, how can I determine of what it's an IList<>?

Here's the gutsy solution. It assumes you have the actual object to test (rather than a Type).

public static Type ListOfWhat(Object list)
{
    return ListOfWhat2((dynamic)list);
}

private static Type ListOfWhat2<T>(IList<T> list)
{
    return typeof(T);
}

Example usage:

object value = new ObservableCollection<DateTime>();
ListOfWhat(value).Dump();

Prints

typeof(DateTime)

This solution sort by Col1 and group by Col2. Then extract value of Col2 and display it in a mbox.

var grouped = from DataRow dr in dt.Rows orderby dr["Col1"] group dr by dr["Col2"];
string x = "";
foreach (var k in grouped) x += (string)(k.ElementAt(0)["Col2"]) + Environment.NewLine;
MessageBox.Show(x);

One way is to just leave merged feature branches open (and inactive):

$ hg up default
$ hg merge feature-x
$ hg ci -m merge

$ hg heads
    (1 head)

$ hg branches
default    43:...
feature-x  41:...
    (2 branches)

$ hg branches -a
default    43:...
    (1 branch)

Another way is to close a feature branch before merging using an extra commit:

$ hg up feature-x
$ hg ci -m 'Closed branch feature-x' --close-branch
$ hg up default
$ hg merge feature-x
$ hg ci -m merge

$ hg heads
    (1 head)

$ hg branches
default    43:...
    (1 branch)

The first one is simpler, but it leaves an open branch. The second one leaves no open heads/branches, but it requires one more auxiliary commit. One may combine the last actual commit to the feature branch with this extra commit using --close-branch, but one should know in advance which commit will be the last one.

Update: Since Mercurial 1.5 you can close the branch at any time so it will not appear in both hg branches and hg heads anymore. The only thing that could possibly annoy you is that technically the revision graph will still have one more revision without childen.

Update 2: Since Mercurial 1.8 bookmarks have become a core feature of Mercurial. Bookmarks are more convenient for branching than named branches. See also this question:

• Mercurial branching and bookmarks

Try this:

s = s.replaceAll("[,]$", "");

for( ; it != res.end();)
{
    it = res.erase(it);
}

or, more general:

for( ; it != res.end();)
{
    if (smth)
        it = res.erase(it);
    else
        ++it;
}

For those with a git gui bent, you can also use gitk.

Right click on the commit you want to return to and select "Reset master branch to here". Then choose hard from the next menu.

Your question is ambiguous; the first two sentences taken together imply that you believe that space and "period" are non-ASCII characters. This is incorrect. All chars such that ord(char) <= 127 are ASCII characters. For example, your function excludes these characters !"#$%&\'()*+,-./ but includes several others e.g. []{}.

Please step back, think a bit, and edit your question to tell us what you are trying to do, without mentioning the word ASCII, and why you think that chars such that ord(char) >= 128 are ignorable. Also: which version of Python? What is the encoding of your input data?

Please note that your code reads the whole input file as a single string, and your comment ("great solution") to another answer implies that you don't care about newlines in your data. If your file contains two lines like this:

this is line 1
this is line 2

the result would be 'this is line 1this is line 2' ... is that what you really want?

A greater solution would include:

1. a better name for the filter function than onlyascii

2. recognition that a filter function merely needs to return a truthy value if the argument is to be retained:

   def filter_func(char):
       return char == '\n' or 32 <= ord(char) <= 126
   # and later:
   filtered_data = filter(filter_func, data).lower()
   

I would suggest you consider a method like

 IntegerUtilities.isValidInteger(String s)

which you then implement as you see fit. If you want the result carried back - perhaps because you use Integer.parseInt() anyway - you can use the array trick.

 IntegerUtilities.isValidInteger(String s, int[] result)

where you set result[0] to the integer value found in the process.

In the case you have no natural partition value and just want an ordered number regardless of the partition you can just do a row_number over a constant, in the following example i've just used 'X'. Hope this helps someone

select 
    ROW_NUMBER() OVER(PARTITION BY num ORDER BY col1) as aliascol1, 
    period_next_id, period_name_long
from 
(
  select distinct col1, period_name_long, 'X' as num
  from {TABLE} 
) as x

We can solve this by using String Buffer String s;

static String timeConversion(String s) {
   StringBuffer st=new StringBuffer(s);
   for(int i=0;i<=st.length();i++){

       if(st.charAt(0)=='0' && st.charAt(1)=='1' &&st.charAt(8)=='P' ){

You can use hostname command :

ipaddr=$(hostname -I)

-i, --ip-address: Display the IP address(es) of the host. Note that this works only if the host name can be resolved.

-I, --all-ip-addresses: Display all network addresses of the host. This option enumerates all configured addresses on all network interfaces. The loopback interface and IPv6 link-local addresses are omitted. Contrary to option -i, this option does not depend on name resolution. Do not make any assumptions about the order of the output.

String s1=""; // empty string assigned to s1 , s1 has length 0, it holds a value of no length string

String s2=null; // absolutely nothing, it holds no value, you are not assigning any value to s2

so null is not the same as empty.

hope that helps!!!

Array.Equals is comparing the references, not their contents:

Currently, when you compare two arrays with the = operator, we are really using the System.Object's = operator, which only compares the instances. (i.e. this uses reference equality, so it will only be true if both arrays points to the exact same instance)

Source

If you want to compare the contents of the arrays you need to loop though the arrays and compare the elements.

The same blog post has an example of how to do this.

 arrList.set(5,newValue);

and if u want to update it then add this line also

 youradapater.NotifyDataSetChanged();

One way I found that helps with this is to use \include{file_with_tex_figure_commands}

Ran into the same problem in Spark 2.0.2. Resolved it by feeding it the jars. Here's what I ran:

$ spark-shell --jars aws-java-sdk-1.7.4.jar,hadoop-aws-2.7.3.jar,jackson-annotations-2.7.0.jar,jackson-core-2.7.0.jar,jackson-databind-2.7.0.jar,joda-time-2.9.6.jar

scala> val hadoopConf = sc.hadoopConfiguration
scala> hadoopConf.set("fs.s3.impl","org.apache.hadoop.fs.s3native.NativeS3FileSystem")
scala> hadoopConf.set("fs.s3.awsAccessKeyId",awsAccessKeyId)
scala> hadoopConf.set("fs.s3.awsSecretAccessKey", awsSecretAccessKey)
scala> val sqlContext = new org.apache.spark.sql.SQLContext(sc)
scala> sqlContext.read.parquet("s3://your-s3-bucket/")

obviously, you need to have the jars in the path where you're running spark-shell from

For InstallShield MSI based projects I have found the following to work:

setup.exe /s /x /b"C:\FolderInWhichMSIWillBeExtracted" /v"/qn"

This command will lead to an extracted MSI in a directory you can freely specify and a silently failed uninstall of the product.

The command line basically tells the setup.exe to attempt to uninstall the product (/x) and do so silently (/s). While doing that it should extract the MSI to a specific location (/b).

The /v command passes arguments to Windows Installer, in this case the /qn argument. The /qn argument disables any GUI output of the installer.

See jsocket. Haven't used it myself. Been more than 3 years since last update (as of 26/6/2014).

* Uses flash :(

From the documentation:

<script type='text/javascript'>
    // Host we are connecting to
    var host = 'localhost'; 
    // Port we are connecting on
    var port = 3000;

    var socket = new jSocket();

    // When the socket is added the to document 
    socket.onReady = function(){
            socket.connect(host, port);             
    }

    // Connection attempt finished
    socket.onConnect = function(success, msg){
            if(success){
                    // Send something to the socket
                    socket.write('Hello world');            
            }else{
                    alert('Connection to the server could not be estabilished: ' + msg);            
            }       
    }
    socket.onData = function(data){
            alert('Received from socket: '+data);   
    }

    // Setup our socket in the div with the id="socket"
    socket.setup('mySocket');

As of AngularJS 1.1.3, you can now do exactly what you want using the new catch-all parameter.

https://github.com/angular/angular.js/commit/7eafbb98c64c0dc079d7d3ec589f1270b7f6fea5

From the commit:

This allows routeProvider to accept parameters that matches substrings even when they contain slashes if they are prefixed with an asterisk instead of a colon. For example, routes like edit/color/:color/largecode/*largecode will match with something like this http://appdomain.com/edit/color/brown/largecode/code/with/slashs.

I have tested it out myself (using 1.1.5) and it works great. Just keep in mind that each new URL will reload your controller, so to keep any kind of state, you may need to use a custom service.

You can try something like this I guess:

new_str = ""
str_value = "rojbasr"
for i in str_value:
    new_str += "0x%s " % (i.encode('hex'))
print new_str

Your output would be something like this:

0x72 0x6f 0x6a 0x62 0x61 0x73 0x72

It might not look that clean but you can have your Dockerfile (conditional) as follow:

FROM centos:7
ARG arg
RUN if [[ -z "$arg" ]] ; then echo Argument not provided ; else echo Argument is $arg ; fi

and then build the image as:

docker build -t my_docker . --build-arg arg=45

or

docker build -t my_docker .

My home-grown regular expression replace function can be used for this.

Demo

See this DB-Fiddle demo, which returns the second word ("I") from a famous sonnet and the number of occurrences of it (1).

SQL

Assuming MySQL 8 or later is being used (to allow use of a Common Table Expression), the following will return the second word and the number of occurrences of it:

WITH cte AS (
     SELECT digits.idx,
            SUBSTRING_INDEX(SUBSTRING_INDEX(words, '~', digits.idx + 1), '~', -1) word
     FROM
     (SELECT reg_replace(UPPER(txt),
                         '[^''’a-zA-Z-]+',
                         '~',
                         TRUE,
                         1,
                         0) AS words
      FROM tbl) delimited
     INNER JOIN
     (SELECT @row := @row + 1 as idx FROM 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t1,
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t2, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t3, 
      (SELECT 0 UNION ALL SELECT 1 UNION ALL SELECT 3 UNION ALL SELECT 4 UNION ALL SELECT 5 UNION ALL SELECT 6 UNION ALL SELECT 6 UNION ALL SELECT 7 UNION ALL SELECT 8 UNION ALL SELECT 9) t4, 
      (SELECT @row := -1) t5) digits
     ON LENGTH(REPLACE(words, '~' , '')) <= LENGTH(words) - digits.idx)
SELECT c.word,
       subq.occurrences
FROM cte c
LEFT JOIN (
  SELECT word,
         COUNT(*) AS occurrences
  FROM cte
  GROUP BY word
) subq
ON c.word = subq.word
WHERE idx = 1; /* idx is zero-based so 1 here gets the second word */

Explanation

A few tricks are used in the SQL above and some accreditation is needed. Firstly the regular expression replacer is used to replace all continuous blocks of non-word characters - each being replaced by a single tilda (~) character. Note: A different character could be chosen instead if there is any possibility of a tilda appearing in the text.

The technique from this answer is then used for transforming a string with delimited values into separate row values. It's combined with the clever technique from this answer for generating a table consisting of a sequence of incrementing numbers: 0 - 10,000 in this case.

1. Make the servlet filter implement the spring Ordered interface.
2. Declare the servlet filter bean manually in configuration class.

    import org.springframework.core.Ordered;
    
    public class MyFilter implements Filter, Ordered {

        @Override
        public void init(FilterConfig filterConfig) {
            // do something
        }

        @Override
        public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
            // do something
        }

        @Override
        public void destroy() {
            // do something
        }

        @Override
        public int getOrder() {
            return -100;
        }
    }


    import org.springframework.context.annotation.ComponentScan;
    import org.springframework.context.annotation.Configuration;

    @Configuration
    @ComponentScan
    public class MyAutoConfiguration {

        @Bean
        public MyFilter myFilter() {
            return new MyFilter();
        }
    }

I think both answers here works ok for the list provided (which answer the original question), but would breaks if an array containing non unique values is passed. So for completeness, I would just point out the small error in each and explain how to fix them.

For example trying to sort the following array [12,4,5,6,7,3,1,15,1] (Note that 1 appears twice) with Brionius algorithm .. at some point will end up with the less array empty and the equal array with a pair of values (1,1) that can not be separated in the next iteration and the len() > 1...hence you'll end up with an infinite loop

You can fix it by either returning array if less is empty or better by not calling sort in your equal array, as in zangw answer

def sort(array=[12,4,5,6,7,3,1,15]):
    less = []
    equal = []
    greater = []

    if len(array) > 1:
        pivot = array[0]
        for x in array:
            if x < pivot:
                less.append(x)
            if x == pivot:
                equal.append(x)
            if x > pivot:
                greater.append(x)

        # Don't forget to return something!
        return sort(less)+ equal +sort(greater)  # Just use the + operator to join lists
    # Note that you want equal ^^^^^ not pivot
    else:  # You need to hande the part at the end of the recursion - when you only have one element in your array, just return the array.
        return array

The fancier solution also breaks, but for a different cause, it is missing the return clause in the recursion line, which will cause at some point to return None and try to append it to a list ....

To fix it just add a return to that line

def qsort(arr): 
   if len(arr) <= 1:
      return arr
   else:
      return qsort([x for x in arr[1:] if x<arr[0]]) + [arr[0]] + qsort([x for x in arr[1:] if x>=arr[0]])

#nav ul {
    display: inline-block;
    list-style-type: none;
}

It should work, I tested it in your site.

InnoDB allows you to add a new foreign key constraint to a table by using ALTER TABLE:

ALTER TABLE tbl_name
    ADD [CONSTRAINT [symbol]] FOREIGN KEY
    [index_name] (index_col_name, ...)
    REFERENCES tbl_name (index_col_name,...)
    [ON DELETE reference_option]
    [ON UPDATE reference_option]

On the other hand, if MyISAM has advantages over InnoDB in your context, why would you want to create foreign key constraints at all. You can handle this on the model level of your application. Just make sure the columns which you want to use as foreign keys are indexed!

Select A.ARIDNR,A.LIEFNR
from Table A
join Table B
on A.ARIDNR = B.ARIDNR
and A.LIEFNR<> B.LIEFNR
group by A.ARIDNR,A.LIEFNR

Matching Anything but Given Strings

If you want to match the entire string where you want to match everything but certain strings you can do it like this:

^(?!(red|green|blue)$).*$

This says, start the match from the beginning of the string where it cannot start and end with red, green, or blue and match anything else to the end of the string.

You can try it here: https://regex101.com/r/rMbYHz/2

Note that this only works with regex engines that support a negative lookahead.

If you use Robert Harder's Base64 utility, then you can do:

InputStream is = new Base64.InputStream(cph);

Or with sun's JRE, you can do:

InputStream is = new
com.sun.xml.internal.messaging.saaj.packaging.mime.util.BASE64DecoderStream(cph)

However don't rely on that class continuing to be a part of the JRE, or even continuing to do what it seems to do today. Sun say not to use it.

There are other Stack Overflow questions about Base64 decoding, such as this one.

i think it should be

select convert(varchar(10),StandardCost) +'S' from DimProduct where ProductKey = 212

or

select cast(StandardCost as varchar(10)) + 'S' from DimProduct where ProductKey = 212

According to the latest documentation about PyMongo titled Insert a Document (insert is deprecated) and following defensive approach, you should insert and update as follows:

result = mycollection.insert_one(post)
post = mycollection.find_one({'_id': result.inserted_id})

if post is not None:
    post['newfield'] = "abc"
    mycollection.save(post)

var http = require('http');
var url  = require('url');
var fs   = require('fs');

var neededstats = [];

http.createServer(function(req, res) {
    if (req.url == '/index.html' || req.url == '/') {
        fs.readFile('./index.html', function(err, data) {
            res.end(data);
        });
    } else {
        var p = __dirname + '/' + req.params.filepath;
        fs.stat(p, function(err, stats) {
            if (err) {
                throw err;
            }
            neededstats.push(stats.mtime);
            neededstats.push(stats.size);
            res.send(neededstats);
        });
    }
}).listen(8080, '0.0.0.0');
console.log('Server running.');

I have not tested your code but other things works

If you want to get the path info from request url

 var url_parts = url.parse(req.url);
 console.log(url_parts);
 console.log(url_parts.pathname);

1.If you are getting the URL parameters still not able to read the file just correct your file path in my example. If you place index.html in same directory as server code it would work...

2.if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs

If you want raw solution to file path

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

function start() {
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}

http.createServer(onRequest).listen(8888);
console.log("Server has started.");
}

exports.start = start;

To get size of emf file without EMF Image Reader you can use code:

Dimension getImageDimForEmf(final String path) throws IOException {

    ImageInputStream inputStream = new FileImageInputStream(new File(path));

    inputStream.setByteOrder(ByteOrder.LITTLE_ENDIAN);

    // Skip magic number and file size
    inputStream.skipBytes(6*4);

    int left   = inputStream.readInt();
    int top    = inputStream.readInt();
    int right  = inputStream.readInt();
    int bottom = inputStream.readInt();

    // Skip other headers
    inputStream.skipBytes(30);

    int deviceSizeInPixelX = inputStream.readInt();
    int deviceSizeInPixelY = inputStream.readInt();

    int deviceSizeInMlmX = inputStream.readInt();
    int deviceSizeInMlmY = inputStream.readInt();

    int widthInPixel = (int) Math.round(0.5 + ((right - left + 1.0) * deviceSizeInPixelX / deviceSizeInMlmX) / 100.0);
    int heightInPixel = (int) Math.round(0.5 + ((bottom-top + 1.0) * deviceSizeInPixelY / deviceSizeInMlmY) / 100.0);

    inputStream.close();

    return new Dimension(widthInPixel, heightInPixel);
}

In Sql the with statement specifies a temporary named result set, known as a common table expression (CTE). It can be used for recursive queries, but in this case, it specifies as subset. If mysql allows for subselectes i would try

select t1.*

                    userinfo.*, 
                    category.* 
            FROM    question INNER JOIN 
                    userinfo ON userinfo.user_userid=article.article_ownerid INNER JOIN category ON article.article_categoryid=category.catid
            WHERE   article.article_isdeleted = 0
     ) t1
ORDER BY t1.article_date DESC Limit 1, 3

On PyCharm Community or Professional Edition 2019.1+ :

1. From the menu bar click Run -> Edit Configurations
2. Add your arguments in the Parameters textbox (for example file2.txt file3.txt, or --myFlag myArg --anotherFlag mySecondArg)
3. Click Apply
4. Click OK

Solution that works for me is adding event listener to paste event if you are pasting to a text input. Since paste event happens before text in input changes, inside my on paste handler I create a deferred function inside which I check for changes in my input box that happened on paste:

onPaste: function() {
    var oThis = this;
    setTimeout(function() { // Defer until onPaste() is done
        console.log('paste', oThis.input.value);
        // Manipulate pasted input
    }, 1);
}

This happened to me also, while i was reading text containing Hebrew from a .txt file.

I clicked: file -> save as and I saved this file as a UTF-8 encoding

I found out this was the easiest way to get access to the clipboard from python:

1) Install pyperclip: pip install pyperclip

2) Usage:

import pyperclip

s = pyperclip.paste()
pyperclip.copy(s)

# the type of s is string

Tested on Win10 64-bit, Python 3.5 and Python 3.7.3 (64-bit). Seems to work with non-ASCII characters, too. Tested characters include ±°©©aß????Fåäö

You might want to look at the Pyxplot plotting package http://pyxplot.org.uk which has very similar syntax to gnuplot, but with the rough edges cleaned up. It handles colors and line styles quite neatly, and homogeneously between x11 and eps/pdf terminals.

The Pyxplot script for what you want to do above would be:

set style 1 lt 1 lw 3 color red
set style 2 lt 1 lw 3 color blue
set style 3 lt 2 lw 3 color red
set style 4 lt 2 lw 3 color blue
plot 'data1.dat' using 1:3 w l style 1,\
  'data1.dat' using 1:4 w l style 2,\
  'data2.dat' using 1:3 w l style 3,\
  'data2.dat' using 1:4 w l style 4`

It might be better to remove related files by using bash to read commands, like the following:

sudo python setup.py install --record files.txt
sudo bash -c "cat files.txt | xargs rm -rf"

Further to pensz answer you can get more info using:

DESCRIBE EXTENDED my_table;

or

DESCRIBE EXTENDED my_table PARTITION (my_column='my_value');

Please change your javascript function as like below....

$(function () {
        $("#projectKey").change(function () {
            alert($('option:selected').text());
        });
    });

You do not need to use $(this) in alert.

It's just a way for the developer to be able to easily identify files which are meant to be used as includes. It's a popular convention. It does not have any special meaning to PHP, and won't change the behaviour of PHP or the script itself.

Actually you can just push query like this: this.$router.push({query: {plan: 'private'}})

Based on: https://github.com/vuejs/vue-router/issues/1631

To remove borders between cells, while retaining the border around the table, add the attribute rules=none to the table tag.

There is no way in HTML to achieve the rendering specified in the last figure of the question. There are various tricky workarounds that are based on using some other markup structure.

In latest ES script, you can do something like this:

let p = {foo: "bar"};_x000D_
for (let [key, value] of Object.entries(p)) {_x000D_
  console.log(key, value);_x000D_
}

Sort each element then look for duplicates. There's a built-in function for sorting so you do not need to import anything

The awk solution is what I would use, but if you want to understand your problems with bash, here is a revised version of your script.

#!/bin/bash -vx

##config file with ip addresses like 10.10.10.1:80
file=config.txt

while read line ; do
  ##this line is not correct, should strip :port and store to ip var
  ip=$( echo "$line" |cut -d\: -f1 )
  ping $ip
done < ${file}

You could write your top line as

for line in $(cat $file) ; do ...

(but not recommended).

You needed command substitution $( ... ) to get the value assigned to $ip

reading lines from a file is usually considered more efficient with the while read line ... done < ${file} pattern.

I hope this helps.

Double and Integer are wrapper classes for Java primitives for double and int respectively. You can cast between those, but you will lose the floating point. That is, 5.4 casted to an int will be 5. If you cast it back, it will be 5.0.

var dataArray = Object.keys(dataObject).map(function(k){return dataObject[k]});

To truncate a string provided by the maximum limit without breaking a word use this:

/**
 * truncate a string provided by the maximum limit without breaking a word
 * @param string $str
 * @param integer $maxlen
 * @return string
 */
public static function truncateStringWords($str, $maxlen): string
{
    if (strlen($str) <= $maxlen) return $str;

    $newstr = substr($str, 0, $maxlen);
    if (substr($newstr, -1, 1) != ' ') $newstr = substr($newstr, 0, strrpos($newstr, " "));

    return $newstr;
}

This debugging code should do the trick well:

You can explore the properties of the Screen Class

Put all displays in an array or list using Screen.AllScreens then capture the index of the current display and its properties.

C# (Converted from VB by Telerik - Please double check)

        {

    List<string> arrDisplayNames = new List<string>();

    foreach (Screen Display in Screen.AllScreens)
    {
        arrAvailableDisplays.Add(Display);
        arrDisplayNames.Add(Display.DeviceName);
    }

    Screen scrCurrentDisplayInfo = Screen.FromControl(this);
    string strDeviceName = Screen.FromControl(this).DeviceName;
    int idxDevice = arrDisplayNames.IndexOf(strDeviceName);

    MessageBox.Show(this, "Number of Displays Found: " + arrAvailableDisplays.Count.ToString() + Constants.vbCrLf + "ID: " + idxDevice.ToString() + Constants.vbCrLf + "Device Name: " + scrCurrentDisplayInfo.DeviceName.ToString + Constants.vbCrLf + "Primary: " + scrCurrentDisplayInfo.Primary.ToString + Constants.vbCrLf + "Bounds: " + scrCurrentDisplayInfo.Bounds.ToString + Constants.vbCrLf + "Working Area: " + scrCurrentDisplayInfo.WorkingArea.ToString + Constants.vbCrLf + "Bits per Pixel: " + scrCurrentDisplayInfo.BitsPerPixel.ToString + Constants.vbCrLf + "Width: " + scrCurrentDisplayInfo.Bounds.Width.ToString + Constants.vbCrLf + "Height: " + scrCurrentDisplayInfo.Bounds.Height.ToString + Constants.vbCrLf + "Work Area Width: " + scrCurrentDisplayInfo.WorkingArea.Width.ToString + Constants.vbCrLf + "Work Area Height: " + scrCurrentDisplayInfo.WorkingArea.Height.ToString, "Current Info for Display '" + scrCurrentDisplayInfo.DeviceName.ToString + "' - ID: " + idxDevice.ToString(), MessageBoxButtons.OK, MessageBoxIcon.Information);

Based on tryingToBeClever solution (which I happened to also stumble upon and fixed myself by trial-and-error before finding it), I also suggest passing the result output of reg query through find in order to filter undesired lines due to the ! REG.EXE VERSION x.y inconsistency. The find filtering and tokens tweaking also allows to pick exactly what we want (typically the value). Also added quotes to avoid unexpected results with key/value names containing spaces.

Final result proposed when we are only interested in fetching the value:

@echo off
setlocal ENABLEEXTENSIONS
set KEY_NAME=HKCU\Software\Microsoft\Command Processor
set VALUE_NAME=DefaultColor
for /F "usebackq tokens=1,2,*" %%A IN (`reg query "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul ^| find "%VALUE_NAME%"`) do (
  echo %%C
)

A potential caveat of using find is that the errorlevel set by reg when errors occur is now obfuscated so one should only use this approach for keys known to be there and/or after a previous validation.

A tiny additional optimization (add skip=1 to avoid processing the first line of output) can be done in cases when the key name also contains the value name (as it is the case with HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion and CurrentVersion) but removes most flexibility so should only be used in particular use-cases.

There is one "trick" for this problem that fits all scenarios, a so obvious solution that you will have to try it to believe it actually works... :)

Here it is...

<IfModule mod_rewrite.c>

   RewriteEngine On

   RewriteCond %{REQUEST_FILENAME}  -f [OR]
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule ^(.*)$ index.php [L,QSA]

</IfModule>

Basically, you are asking MOD_REWRITE to forward to index.php the URI request always when a file exists AND always when the requested file doesn't exist!

When investigating the source code of MOD-REWRITE to understand how it works I realized that all its checks always happen after the verification if the referenced file exists or not. Only then the RegEx are processed. Even when your URI points to a folder, Apache will enforce the check for the index files listed in its configuration file.

Based on that simple discovery, turned obvious a simple file validation would be enough for all possible calls, as far as we double-tap the file presence check and route both results to the same end-point, covering 100% of the possibilities.

IMPORTANT: Notice there is no "/" in index.php. By default, MOD_REWRITE will use the folder it is set as "base folder" for the forwarding. The beauty of it is that it doesn't necessarily need to be the "root folder" of the site, allowing this solution work for localhost/ and/or any subfolder you apply it.

Ultimately, some other solutions I tested before (the ones that appeared to be working fine) broke the PHP ability to "require" a file via its relative path, which is a bummer. Be careful.

Some people may say this is an inelegant solution. It may be, actually, but as far as tests, in several scenarios, several servers, several different Apache versions, etc., this solution worked 100% on all cases!

With regard to Brent.Longborough's answer (appering only on page 2 onward), perhaps you need to set the \thispagestyle{} after \begin{document}. I wonder if the letter class is setting the first page style to empty.

Here is the easy solution of port finding...

In cmd:

netstat -na | find "8080"

In bash:

netstat -na | grep "8080"

In PowerShell:

netstat -na | Select-String "8080"

Syntax highlighting is controlled by the theme you use, accessible through Preferences -> Color Scheme. Themes highlight different keywords, functions, variables, etc. through the use of scopes, which are defined by a series of regular expressions contained in a .tmLanguage file in a language's directory/package. For example, the JavaScript.tmLanguage file assigns the scopes source.js and variable.language.js to the this keyword. Since Sublime Text 3 is using the .sublime-package zip file format to store all the default settings it's not very straightforward to edit the individual files.

Unfortunately, not all themes contain all scopes, so you'll need to play around with different ones to find one that looks good, and gives you the highlighting you're looking for. There are a number of themes that are included with Sublime Text, and many more are available through Package Control, which I highly recommend installing if you haven't already. Make sure you follow the ST3 directions.

As it so happens, I've developed the Neon Color Scheme, available through Package Control, that you might want to take a look at. My main goal, besides trying to make a broad range of languages look as good as possible, was to identify as many different scopes as I could - many more than are included in the standard themes. While the JavaScript language definition isn't as thorough as Python's, for example, Neon still has a lot more diversity than some of the defaults like Monokai or Solarized.

I should note that I used @int3h's Better JavaScript language definition for this image instead of the one that ships with Sublime. It can be installed via Package Control.

UPDATE

Of late I've discovered another JavaScript replacement language definition - JavaScriptNext - ES6 Syntax. It has more scopes than the base JavaScript or even Better JavaScript. It looks like this on the same code:

Also, since I originally wrote this answer, @skuroda has released PackageResourceViewer via Package Control. It allows you to seamlessly view, edit and/or extract parts of or entire .sublime-package packages. So, if you choose, you can directly edit the color schemes included with Sublime.

ANOTHER UPDATE

With the release of nearly all of the default packages on Github, changes have been coming fast and furiously. The old JS syntax has been completely rewritten to include the best parts of JavaScript Next ES6 Syntax, and now is as fully ES6-compatible as can be. A ton of other changes have been made to cover corner and edge cases, improve consistency, and just overall make it better. The new syntax has been included in the (at this time) latest dev build 3111.

If you'd like to use any of the new syntaxes with the current beta build 3103, simply clone the Github repo someplace and link the JavaScript (or whatever language(s) you want) into your Packages directory - find it on your system by selecting Preferences -> Browse Packages.... Then, simply do a git pull in the original repo directory from time to time to refresh any changes, and you can enjoy the latest and greatest! I should note that the repo uses the new .sublime-syntax format instead of the old .tmLanguage one, so they will not work with ST3 builds prior to 3084, or with ST2 (in both cases, you should have upgraded to the latest beta or dev build anyway).

I'm currently tweaking my Neon Color Scheme to handle all of the new scopes in the new JS syntax, but most should be covered already.

Underneath the file system, files are represented by inodes. (Or is it multiple inodes? Not sure.)

A file in the file system is basically a link to an inode.
A hard link, then, just creates another file with a link to the same underlying inode.

When you delete a file, it removes one link to the underlying inode. The inode is only deleted (or deletable/over-writable) when all links to the inode have been deleted.

A symbolic link is a link to another name in the file system.

Once a hard link has been made the link is to the inode. Deleting, renaming, or moving the original file will not affect the hard link as it links to the underlying inode. Any changes to the data on the inode is reflected in all files that refer to that inode.

Note: Hard links are only valid within the same File System. Symbolic links can span file systems as they are simply the name of another file.

I required a thread to fire once every minute (see question here) and I've now used a DispatchTimer based on the answers I received.

The answers provide some references which you might find useful.

That's not even valid syntax. And you're trying to compare to a string. For arrays you would have to walk the array yourself:

public class T {
  public static void main( String args[] ) {
    char[] list = {'m', 'e', 'y'};

    int index = -1;

    for (int i = 0; (i < list.length) && (index == -1); i++) {
        if (list[i] == 'e') {
            index = i;
        }
    }

    System.out.println(index);
  }
}

If you are using a collection, such as ArrayList<Character> you can also use the indexOf() method:

ArrayList<Character> list = new ArrayList<Character>();
list.add('m');
list.add('e');
list.add('y');

System.out.println(list.indexOf('e'));

There is also the Arrays class which shortens above code:

List list = Arrays.asList(new Character[] { 'm', 'e', 'y' });
System.out.println(list.indexOf('e'));

Building workspace is about incremental build of any evolution detected in one of the opened projects in the currently used workspace.

You can also disable it through the menu "Project / Build automatically".

But I would recommend first to check:

• if a Project Clean all / Build result in the same kind of long wait (after disabling this option)
• if you have (this time with building automatically activated) some validation options you could disable to see if they have an influence on the global compilation time (Preferences / Validations, or Preferences / XML / ... if you have WTP installed)
• if a fresh eclipse installation referencing the same workspace (see this eclipse.ini for more) results in the same issue (with building automatically activated)

Note that bug 329657 (open in 2011, in progress in 2014) is about interrupting a (too lengthy) build, instead of cancelling it:

There is an important difference between build interrupt and cancel.

• When a build is cancelled, it typically handles this by discarding incremental build state and letting the next build be a full rebuild. This can be quite expensive in some projects.
  As a user I think I would rather wait for the 5 second incremental build to finish rather than cancel and result in a 30 second rebuild afterwards.

• The idea with interrupt is that a builder could more efficiently handle interrupt by saving its intermediate state and resuming on the next invocation.
  In practice this is hard to implement so the most common boundary is when we check for interrupt before/after calling each builder in the chain.

Cava Packager is great on the Windows ecosystem.

<font size="4"> <font color="#ffe680">something here</font><br>

I was trying all these methods but most didn't work properly for me, eventually I accidentally did this and it works great, it works on chrome and safari (the only things I tested on). Replace the colour code thing with your background colour code and the text will be invisible. you can also adjust the font size to make the line break bigger or smaller depending on your desire. It is really simple.

If you do not want to use jQuery, make the button type a normal button and add a click listener pointing to the function you would like to execute, and send the form in as a parameter. The button would be as follows:

<button (click)="yourSubmitFunction(yourForm)" [disabled]="!yourForm.valid" type="button" class="btn btn-primary" data-dismiss="modal">Save changes</button>

Remember to remove: (ngSubmit)="yourSubmitFunction(yourForm)" from the form div if you use this method.

This does not need jquery, you could set a variable inside the if and use it in html or pass it thru your template system if any

<?php
$showDivFlag=false
$query3 = mysql_query($query3);
$numrows = mysql_num_rows($query3);
if ($numrows > 0){
    $fvisit = mysql_fetch_array($result3);
    $showDivFlag=true;
 }else {

 }

?>

later in html

  <div id="results" <?php if ($showDivFlag===false){?>style="display:none"<?php } ?>>

This match 6 or more any chars but newline:

/^.{6,}$/

var str = "The rain in SPAIN stays mainly in the plain";

function searchIndex(str, searchValue, isCaseSensitive) {
  var modifiers = isCaseSensitive ? 'gi' : 'g';
  var regExpValue = new RegExp(searchValue, modifiers);
  var matches = [];
  var startIndex = 0;
  var arr = str.match(regExpValue);

  [].forEach.call(arr, function(element) {
    startIndex = str.indexOf(element, startIndex);
    matches.push(startIndex++);
  });

  return matches;
}

console.log(searchIndex(str, 'ain', true));

As said by @Nancom

<mvc:resources location="/resources/" mapping="/resource/**"/>

So for clarity lets our image is in

resources/images/logo.png"

The location attribute of the mvc:resources tag defines the base directory location of static resources that you want to serve. It can be images path that are available under the src/main/webapp/resources/images/ directory; you may wonder why we have given only /resources/ as the location value instead of src/main/webapp/resources/images/. This is because we consider the resources directory as the base directory for all resources, we can have multiple sub-directories under resources directory to put our images and other static resource files.

The second attribute, mapping, just indicates the request path that needs to be mapped to this resources directory. In our case, we have assigned /resource/** as the mapping value. So, if any web request starts with the /resource request path, then it will be mapped to the resources directory, and the /** symbol indicates the recursive look for any resource files underneath the base resources directory.

So for url like http://localhost:8080/webstore/resource/images/logo.png. So, while serving this web request, Spring MVC will consider /resource/images/logo.png as the request path. So, it will try to map /resource to the base directory specified by the location attribute, resources. From this directory, it will try to look for the remaining path of the URL, which is /images/logo.png. Since we have the images directory under the resources directory, Spring can easily locate the image file from the images directory.

So

 <mvc:resources location="/resources/" mapping="/resource/**"/>

gives us for given [requests] -> [resource mapping]:

http://localhost:8080/webstore/resource/images/logo.png -> searches in resources/images/logo.png

http://localhost:8080/webstore/resource/images/small/picture.png -> searches in resources/images/small/picture.png

http://localhost:8080/webstore/resource/css/main.css -> searches in resources/css/main.css

http://localhost:8080/webstore/resource/pdf/index.pdf -> searches in resources/pdf/index.pdf

Use:

/*/ITEM[starts-with(REVENUE_YEAR,'2552')]/REGION

Note: Unless your host language can't handle element instance as result, do not use text nodes specially in mixed content data model. Do not start expressions with // operator when the schema is well known.

If you look to run a method on ngOnInit you could do something like this:

import this 2 libraries from RXJS:

import {Observable} from 'rxjs/Rx';
import {Subscription} from "rxjs";

Then declare timer and private subscription, example:

timer= Observable.timer(1000,1000); // 1 second for 2 seconds (2000,1000) etc
private subscription: Subscription;

Last but not least run method when timer stops

ngOnInit() {
  this.subscription = this.timer.subscribe(ticks=> {
    this.populatecombobox();  //example calling a method that populates a combobox
    this.subscription.unsubscribe();  //you need to unsubscribe or it will run infinite times
  });
}

That's all, Angular 5

I kept having problems with this, the only solution was to add an image and label as subviews to the uibutton. Then I discovered that the main problem was that I was using a UIButton with title: Attributed. When I changed it to Plain, just setting the titleLabel.text did the trick!

Make sure you're in the right database context in SSMS. Got the same error as you, but I knew the schema already existed. Didn't realize I was in 'MASTER' context. ALTER worked after I changed context to my database.

SQL Server (2005, 2000, 7.0) does not have any flexible, or even non-flexible, way of taking an arbitrarily structured datetime in string format and converting it to the datetime data type.

By "arbitrarily", I mean "a form that the person who wrote it, though perhaps not you or I or someone on the other side of the planet, would consider to be intuitive and completely obvious." Frankly, I'm not sure there is any such algorithm.

If you only want to change form's action, I prefer changing action on-form-submit, rather than on-input-change. It fires only once.

$('#search-form').submit(function(){
  var formAction = $("#selectsearch").val() == "people" ? "user" : "content";
  $("#search-form").attr("action", "/search/" + formAction);
}); 

Please find example below, it might help you

package jersey.rest.test;

import javax.ws.rs.DELETE;
import javax.ws.rs.GET;
import javax.ws.rs.HEAD;
import javax.ws.rs.POST;
import javax.ws.rs.PUT;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.core.Response;

@Path("/hello")
public class SimpleService {
    @GET
    @Path("/{param}")
    public Response getMsg(@PathParam("param") String msg) {
        String output = "Get:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/{param}")
    public Response postMsg(@PathParam("param") String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @POST
    @Path("/post")
    //@Consumes(MediaType.TEXT_XML)
    public Response postStrMsg( String msg) {
        String output = "POST:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @PUT
    @Path("/{param}")
    public Response putMsg(@PathParam("param") String msg) {
        String output = "PUT: Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @DELETE
    @Path("/{param}")
    public Response deleteMsg(@PathParam("param") String msg) {
        String output = "DELETE:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }

    @HEAD
    @Path("/{param}")
    public Response headMsg(@PathParam("param") String msg) {
        String output = "HEAD:Jersey say : " + msg;
        return Response.status(200).entity(output).build();
    }
}

for testing you can use any tool like RestClient (http://code.google.com/p/rest-client/)

I just figured this out, at least in my use case.

I was getting ECONNRESET. It turned out that the way my client was set up, it was hitting the server with an API call a ton of times really quickly -- and it only needed to hit the endpoint once.

When I fixed that, the error was gone.

This has been enhanced in v23.0.0 of AppCompat library with the addition of more themes including

Widget.AppCompat.Button.Colored

First of all include appCompat dependency if you haven't already

compile('com.android.support:appcompat-v7:23.0.0') {
    exclude group: 'com.google.android', module: 'support-v4'
}

now since you need to use v23 of the app compat, you'll need to target SDK-v23 as well!

    compileSdkVersion = 23
    targetSdkVersion = 23

In your values/theme

<item name="android:buttonStyle">@style/BrandButtonStyle</item>

In your values/style

<style name="BrandButtonStyle" parent="Widget.AppCompat.Button.Colored">
    <item name="colorButtonNormal">@color/yourButtonColor</item>
    <item name="android:textColor">@color/White</item>
</style>

In your values-v21/style

<style name="BrandButtonStyle" parent="Widget.AppCompat.Button.Colored">
    <item name="android:colorButtonNormal">@color/yourButtonColor</item>
    <item name="android:textColor">@color/White</item>
</style>

Since your button theme is based on Widget.AppCompat.Button.Colored The text color on the button is by default white!

but it seems there is an issue when you disable the button, the button will change its color to light grey, but the text color will remain white!

a workaround for this is to specifically set the text color on the button to white! as I have done in the style shown above.

now you can simply define your button and let AppCompat do the rest :)

<Button
        android:layout_width="200dp"
        android:layout_height="48dp" />

Disabled State

Enabled State

Edit:

To add <Button android:theme="@style/BrandButtonStyle"/>

In such case you will need to parse zip local header entries. Each file, stored in zip file, has preceding Local File Header entry, which (normally) contains enough information for decompression, Generally, you can make simple parsing of such entries in stream, select needed file, copy header + compressed file data to other file, and call unzip on that part (if you don't want to deal with the whole Zip decompression code or library).

They both are very different. Docker is lightweight and uses LXC/libcontainer (which relies on kernel namespacing and cgroups) and does not have machine/hardware emulation such as hypervisor, KVM. Xen which are heavy.

Docker and LXC is meant more for sandboxing, containerization, and resource isolation. It uses the host OS's (currently only Linux kernel) clone API which provides namespacing for IPC, NS (mount), network, PID, UTS, etc.

What about memory, I/O, CPU, etc.? That is controlled using cgroups where you can create groups with certain resource (CPU, memory, etc.) specification/restriction and put your processes in there. On top of LXC, Docker provides a storage backend (http://www.projectatomic.io/docs/filesystems/) e.g., union mount filesystem where you can add layers and share layers between different mount namespaces.

This is a powerful feature where the base images are typically readonly and only when the container modifies something in the layer will it write something to read-write partition (a.k.a. copy on write). It also provides many other wrappers such as registry and versioning of images.

With normal LXC you need to come with some rootfs or share the rootfs and when shared, and the changes are reflected on other containers. Due to lot of these added features, Docker is more popular than LXC. LXC is popular in embedded environments for implementing security around processes exposed to external entities such as network and UI. Docker is popular in cloud multi-tenancy environment where consistent production environment is expected.

A normal VM (for example, VirtualBox and VMware) uses a hypervisor, and related technologies either have dedicated firmware that becomes the first layer for the first OS (host OS, or guest OS 0) or a software that runs on the host OS to provide hardware emulation such as CPU, USB/accessories, memory, network, etc., to the guest OSes. VMs are still (as of 2015) popular in high security multi-tenant environment.

Docker/LXC can almost be run on any cheap hardware (less than 1 GB of memory is also OK as long as you have newer kernel) vs. normal VMs need at least 2 GB of memory, etc., to do anything meaningful with it. But Docker support on the host OS is not available in OS such as Windows (as of Nov 2014) where as may types of VMs can be run on windows, Linux, and Macs.

Here is a pic from docker/rightscale :

As there is comment by @johnkarka on the question, this port is used by SQL Server reporting service as well. After stopping this, Apache started fine.

1. Go to "SQL Server Configuration Manager"
2. Click on "SQL Server Reporting Service" and stop it

The funny thing is IIS was working fine in same configuration but not Apache, had to stop SQL Reporting service to make it work on default port (80).

"No suitable driver" usually means that the JDBC URL you've supplied to connect has incorrect syntax or when the driver isn't loaded at all.

When the method getConnection is called, the DriverManager will attempt to locate a suitable driver from amongst those loaded at initialization and those loaded explicitly using the same classloader as the current applet or application.(using Class.forName())

For Example

import oracle.jdbc.driver.OracleDriver;

Class.forName("oracle.jdbc.driver.­OracleDriver");

Also check that you have ojdbc6.jar in your classpath. I would suggest to place .jar at physical location to JBoss "$JBOSS_HOME/server/default/lib/" directory of your project.

EDIT:

You have mentioned hibernate lately.

Check that your hibernate.cfg.xml file has connection properties something like this:

<property name="hibernate.connection.driver_class">oracle.jdbc.driver.OracleDriver</property>
<property name="hibernate.connection.url">jdbc:oracle:thin:@localhost:1521:orcl</property> 
<property name="hibernate.connection.username">scott</property>
<property name="hibernate.connection.password">tiger</property>

This lifecycle method is invoked as soon as the updating happens. The most common use case for the componentDidUpdate() method is updating the DOM in response to prop or state changes.

You can call setState() in this lifecycle, but keep in mind that you will need to wrap it in a condition to check for state or prop changes from previous state. Incorrect usage of setState() can lead to an infinite loop. Take a look at the example below that shows a typical usage example of this lifecycle method.

componentDidUpdate(prevProps) {
 //Typical usage, don't forget to compare the props
 if (this.props.userName !== prevProps.userName) {
   this.fetchData(this.props.userName);
 }
}

Notice in the above example that we are comparing the current props to the previous props. This is to check if there has been a change in props from what it currently is. In this case, there won’t be a need to make the API call if the props did not change.

For more info, refer to the official docs:
