OK, the right answer definitely has to do something with the CPU cache. But to use the cache argument can be quite difficult, especially without data.

There are many answers, that led to a lot of discussion, but let's face it: Cache issues can be very complex and are not one dimensional. They depend heavily on the size of the data, so my question was unfair: It turned out to be at a very interesting point in the cache graph.

@Mysticial's answer convinced a lot of people (including me), probably because it was the only one that seemed to rely on facts, but it was only one "data point" of the truth.

That's why I combined his test (using a continuous vs. separate allocation) and @James' Answer's advice.

The graphs below shows, that most of the answers and especially the majority of comments to the question and answers can be considered completely wrong or true depending on the exact scenario and parameters used.

Note that my initial question was at n = 100.000. This point (by accident) exhibits special behavior:

1. It possesses the greatest discrepancy between the one and two loop'ed version (almost a factor of three)

2. It is the only point, where one-loop (namely with continuous allocation) beats the two-loop version. (This made Mysticial's answer possible, at all.)

The result using initialized data:

The result using uninitialized data (this is what Mysticial tested):

And this is a hard-to-explain one: Initialized data, that is allocated once and reused for every following test case of different vector size:

Proposal

Every low-level performance related question on Stack Overflow should be required to provide MFLOPS information for the whole range of cache relevant data sizes! It's a waste of everybody's time to think of answers and especially discuss them with others without this information.

It can happen because of native method calling in your application. For example, in Qtjambi if you use QApplication.quit() instead of QApplication.closeAllWindows() for closing a Java application it generates an error log.

In this case, you can get a stack trace right to your method that called the native code and caused the crash. Just look in the log file it tells you about:

# An error report file with more information is saved as hs_err_pid24139.log.

The stack trace looks quite unusual, since it has native code mixed with VM code and your code, but each line is prefixed so you can tell which lines are your own code. There's a key at the top of the stack trace to explain the prefixes:

Native frames: (J=compiled Java code, A=aot compiled Java code, j=interpreted, Vv=VM code, C=native code)

This happens when the pointer passed to free() is not valid or has been modified somehow. I don't really know the details here. The bottom line is that the pointer passed to free() must be the same as returned by malloc(), realloc() and their friends. It's not always easy to spot what the problem is for a novice in their own code or even deeper in a library. In my case, it was a simple case of an undefined (uninitialized) pointer related to branching.

The free() function frees the memory space pointed to by ptr, which must have been returned by a previous call to malloc(), calloc() or realloc(). Otherwise, or if free(ptr) has already been called before, undefined behavior occurs. If ptr is NULL, no operation is performed. GNU 2012-05-10 MALLOC(3)

char *words; // setting this to NULL would have prevented the issue

if (condition) {
    words = malloc( 512 );

    /* calling free sometime later works here */

    free(words)
} else {

    /* do not allocate words in this branch */
}

/* free(words);  -- error here --
*** glibc detected *** ./bin: munmap_chunk(): invalid pointer: 0xb________ ***/

There are many similar questions here about the related free() and rellocate() functions. Some notable answers providing more details:

*** glibc detected *** free(): invalid next size (normal): 0x0a03c978 ***
*** glibc detected *** sendip: free(): invalid next size (normal): 0x09da25e8 ***
glibc detected, realloc(): invalid pointer

IMHO running everything in a debugger (Valgrind) is not the best option because errors like this are often caused by inept or novice programmers. It's more productive to figure out the issue manually and learn how to avoid it in the future.

If the string is already within quotes then use another quote to nullify its action.

Same 404 response I got after service executed with the below code

@Controller
@RequestMapping("/duecreate/v1.0")
public class DueCreateController {

"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/duecreate/v1.0/status"
}

after changing it to below code I received proper response

Many other answers only do formatting. This approach will return value instead of only print format.

double number1 = 10.123456;
double number2 = (int)(Math.round(number1 * 100))/100.0;
System.out.println(number2);

def function(a):
    if a == '1':
        print ('1a')
    else if a == '2'
        print ('2a')
    else print ('3a')

Should be corrected to:

def function(a):
    if a == '1':
        print('1a')
    elif a == '2':
        print('2a')
    else:
        print('3a')

As you can see, else if should be changed to elif, there should be colons after '2' and else, there should be a new line after the else statement, and close the space between print and the parentheses.

Just throwing this out there, but try retyping things manually. There's a chance that your quotation marks are the "wrong" ones as there's a similar unicode character which looks similar but is NOT a quotation mark.

If you copy/pasted the code snippits off a website, that might be your problem.

Here's a custom theme to make the ggplot2 background white and a bunch of other changes that's good for publications and posters. Just tack on +mytheme. If you want to add or change options by +theme after +mytheme, it will just replace those options from +mytheme.

library(ggplot2)
library(cowplot)
theme_set(theme_cowplot())

mytheme = list(
    theme_classic()+
        theme(panel.background = element_blank(),strip.background = element_rect(colour=NA, fill=NA),panel.border = element_rect(fill = NA, color = "black"),
              legend.title = element_blank(),legend.position="bottom", strip.text = element_text(face="bold", size=9),
              axis.text=element_text(face="bold"),axis.title = element_text(face="bold"),plot.title = element_text(face = "bold", hjust = 0.5,size=13))
)

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

1. Enable External option in Unity ? Preferences ? Packages ? Repository
2. Switch to Hidden Meta Files in Editor ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Editor ? Project Settings ? Editor ? Asset Serialization Mode
4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.

More information about keeping Unity Project under source control you can find in this post.

I would use a regex:

import re

Apache Commons has an IntegerValidator class which appears to do what you want. Java provides no in-built method for doing this.

This is very easy by import repository feature Login to github.com,

Side of profile picture you will find + button click on that then there will be option to import repository. you will find page like this. Your old repository’s clone URL is required which is gitlab repo url in your case. then select Owner and then type name for this repo and click to begin import button.

you can't use aliases from select list inside the WHERE clause (because of the Order of Evaluation of a SELECT statement)

also you cannot use OVER clause inside WHERE clause - "You can specify analytic functions with this clause in the select list or ORDER BY clause." (citation from docs.oracle.com)

select *
from (select
  staff_id, site_id, pay_level, date, 
  max(date) over (partition by staff_id) max_date
  from owner.table
  where end_enrollment_date is null
)
where date = max_date

Just add <relativePath /> so the parent in pom should look like:

Could anyone help explain why

In Python 2 a python "int" was equivalent to a C long. In Python 3 an "int" is an arbitrary precision type but numpy still uses "int" it to represent the C type "long" when creating arrays.

The size of a C long is platform dependent. On windows it is always 32-bit. On unix-like systems it is normally 32 bit on 32 bit systems and 64 bit on 64 bit systems.

or give a solution for the code on windows? Thanks so much!

Choose a data type whose size is not platform dependent. You can find the list at https://docs.scipy.org/doc/numpy/reference/arrays.scalars.html#arrays-scalars-built-in the most sensible choice would probably be np.int64

You can try this code into your activity

    private void startWebView(WebView webView,String url) {
 webView.setWebViewClient(new WebViewClient() {
            ProgressDialog progressDialog;

            public boolean shouldOverrideUrlLoading(WebView view, String url) {
                view.loadUrl(url);
                return false;
            }

            @Override
            public void onPageStarted(WebView view, String url, Bitmap favicon) {
                super.onPageStarted(view, url, favicon);
            }

            public void onLoadResource (WebView view, String url) {

                    if (progressDialog == null) {
                        progressDialog = new ProgressDialog(SponceredDetailsActivity.this);
                        progressDialog.setMessage("Loading...");
                        progressDialog.show();
                    }

            }
            public void onPageFinished(WebView view, String url) {
                try{
                    if (progressDialog.isShowing()) {
                        progressDialog.dismiss();
                        progressDialog = null;
                    }

                }catch(Exception exception){
                    exception.printStackTrace();
                }
            }

        });

        webView.getSettings().setJavaScriptEnabled(true);
        webView.loadUrl(url);
    }

Call this method using this way:

startWebView(web_view,"Your Url");

Sometimes if URL is dead it will redirected and it will come to onLoadResource() before onPageFinished method. For this reason progress bar will not dismis. To solve this issue see my this Answer.

Thanks :)

Adding import 'core-js/es7/array'; to my polyfill.ts fixed the issue for me.

(( a = b==5 ? c : d )) # string + numeric

While you can call exit() (and may need to do so if your application encounters some fatal error), the cleanest way to exit a program is to return from main():

int main()
{
    // do whatever your program does

} // function returns and exits program

When you call exit(), objects with automatic storage duration (local variables) are not destroyed before the program terminates, so you don't get proper cleanup. Those objects might need to clean up any resources they own, persist any pending state changes, terminate any running threads, or perform other actions in order for the program to terminate cleanly.

Another option is to use

$_SERVER['REQUEST_METHOD'] == 'POST'

Here is how to add inline code:

You can add inline code with {\tt code } or \texttt{ code }. If you want to format the inline code, then it would be best to make your own command

\newcommand{\code}[1]{\texttt{#1}}

Also, note that code blocks can be loaded from other files with

\lstinputlisting[breaklines]{source.c}

breaklines isn't required, but I find it useful. Be aware that you'll have to specify \usepackage{ listings } for this one.

Update: The listings package also includes the \lstinline command, which has the same syntax highlighting features as the \lstlisting and \lstinputlisting commands (see Cloudanger's answer for configuration details). As mentioned in a few other answers, there's also the minted package, which provides the \mintinline command. Like \lstinline, \mintinline provides the same syntax highlighting as a regular minted code block:

\documentclass{article}

\usepackage{minted}

\begin{document}
  This is a sentence with \mintinline{python}{def inlineCode(a="ipsum)}
\end{document}

This program in java returns "true" if number is a power of 2 and returns "false" if its not a power of 2

// To check if the given number is power of 2

import java.util.Scanner;

public class PowerOfTwo {
    int n;
    void solve() {
        while(true) {
//          To eleminate the odd numbers
            if((n%2)!= 0){
                System.out.println("false");
                break;
            }
//  Tracing the number back till 2
            n = n/2;
//  2/2 gives one so condition should be 1
            if(n == 1) {
                System.out.println("true");
                break;
            }
        }
    }
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        Scanner in = new Scanner(System.in);
        PowerOfTwo obj = new PowerOfTwo();
        obj.n = in.nextInt();
        obj.solve();
    }

}

OUTPUT : 
34
false

My answer is similar to this one on ServerFault.com.

To Be Conservative

If you want to be more conservative than granting "all privileges", you might want to try something more like these.

GRANT SELECT, INSERT, UPDATE, DELETE ON ALL TABLES IN SCHEMA public TO some_user_;
GRANT EXECUTE ON ALL FUNCTIONS IN SCHEMA public TO some_user_;

The use of public there refers to the name of the default schema created for every new database/catalog. Replace with your own name if you created a schema.

Access to the Schema

To access a schema at all, for any action, the user must be granted "usage" rights. Before a user can select, insert, update, or delete, a user must first be granted "usage" to a schema.

You will not notice this requirement when first using Postgres. By default every database has a first schema named public. And every user by default has been automatically been granted "usage" rights to that particular schema. When adding additional schema, then you must explicitly grant usage rights.

GRANT USAGE ON SCHEMA some_schema_ TO some_user_ ;

Excerpt from the Postgres doc:

For schemas, allows access to objects contained in the specified schema (assuming that the objects' own privilege requirements are also met). Essentially this allows the grantee to "look up" objects within the schema. Without this permission, it is still possible to see the object names, e.g. by querying the system tables. Also, after revoking this permission, existing backends might have statements that have previously performed this lookup, so this is not a completely secure way to prevent object access.

For more discussion see the Question, What GRANT USAGE ON SCHEMA exactly do?. Pay special attention to the Answer by Postgres expert Craig Ringer.

Existing Objects Versus Future

These commands only affect existing objects. Tables and such you create in the future get default privileges until you re-execute those lines above. See the other answer by Erwin Brandstetter to change the defaults thereby affecting future objects.

For those of you who came here looking for a way to truncate a DATETIME field to something less than a whole day, for example every minute, you can use this:

SELECT CAST(FLOOR(CAST(GETDATE() AS FLOAT)) + (FLOOR((CAST(GETDATE() AS FLOAT) - FLOOR(CAST(GETDATE() AS FLOAT))) * 1440.0) + (3.0/86400000.0)) / 1440.0 AS DATETIME)

so if today was 2010-11-26 14:54:43.123 then this would return 2010-11-26 14:54:00.000.

To change the interval it trucates to, replace 1440.0 with the number of intervals in a day, for example:

24hrs          =   24.0  (for every hour)
24hrs / 0.5hrs =   48.0  (for every half hour)
24hrs / (1/60) = 1440.0  (for every minute)

(Always put a .0 on the end to implicitly cast to a float.)

For those of you wondering what the (3.0/86400000) is for in my calculation, SQL Server 2005 doesn't seem to cast from FLOAT to DATETIME accurately, so this adds 3 milliseconds before flooring it.

If it doesn't work in the latest version of reactjs, try using innerRef

class MyComponent extends React.Component {


  render() {
    return (
      <div onClick={this.handleClick}>
        <input innerRef={input => this.inputElement = input} />
      </div>
    );
  }

  handleClick = (e) => {
    this.inputElement.click();
  }
}

Depends on your system, just write a sample program [ by creating processes in a loop ] and check using ps axo pid,ppid,rss,vsz,nlwp,cmd. When it can no more create threads check nlwp count [ nlwp is the number threads ] voila you got your fool proof answer instead of going thru books

In Expression Language you can just use the == or eq operator to compare object values. Behind the scenes they will actually use the Object#equals(). This way is done so, because until with the current EL 2.1 version you cannot invoke methods with other signatures than standard getter (and setter) methods (in the upcoming EL 2.2 it would be possible).

So the particular line

<c:when test="${lang}.equals(${pageLang})">

should be written as (note that the whole expression is inside the { and })

<c:when test="${lang == pageLang}">

or, equivalently

<c:when test="${lang eq pageLang}">

Both are behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals(jspContext.findAttribute("pageLang"))

If you want to compare constant String values, then you need to quote it

<c:when test="${lang == 'en'}">

or, equivalently

<c:when test="${lang eq 'en'}">

which is behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals("en")

Here is the implementation of BCrypt which is working for me.

I was having serious problems with

.data('property', value);

It was not setting the data-property attribute.

Started using jQuery's .attr():

Get the value of an attribute for the first element in the set of matched elements or set one or more attributes for every matched element.

.attr('property', value)

to set the value and

.attr('property')

to retrieve the value.

Now it just works!

You can use the zoom property. Check this jsfiddle

If you're wanting to use this functionality for a GreaseMonkey script to automatically check a checkbox on a page, keep in mind that simply setting the checked property may not trigger the associated action. In that case, "clicking" the checkbox probably will (and set the checked property as well).

$("#id").click()

Just posting in case it help someone else. The cause of this error for me was a missing do after creating a form with form_with. Hope that may help someone else

In later versions (tested with TensorFlow 1.14) there's a more numpy-like way to get the shape of a tensor. You can use tensor.shape to get the shape of the tensor.

tensor_shape = tensor.shape
print(tensor_shape)

You just need to make the siprimo and volteado methods static.

private static bool siprimo(long a)

and

private static long volteado(long a)

Viewport units for CSS

In regards to animating images using CSS TranslateX/Y (The proper way to animate html) - If you do a Chrome Timeline recording of CSS background-images being animated vs IMG tags being animated you will see the paint times are drastically shorter for the CSS background-images.

If you don't wish to compile bootstrap, copy the following and insert it in your custom css file. It's not recommended to change the original bootstrap css file. Also, you won't be able to modify the bootstrap original css if you are loading it from a cdn.

Paste this in your custom css file:

@media (min-width:992px)
    {
        .container{width:960px}
    }
@media (min-width:1200px)
    {
        .container{width:960px}
    }

I am here setting my container to 960px for anything that can accommodate it, and keeping the rest media sizes to default values. You can set it to 940px for this problem.

The only way I know to deal with this is to create a new workspace, import projects from the polluted workspace, reconstructing all my settings (a major pain) and then delete the old workspace. Is there an easier way to deal with this?

For synchronizing or restoring all our settings we use Workspace Mechanic. Once all the settings are recorded its one click and all settings are restored... You can also setup a server which provides those settings for all users.

select * from yourtable 
   where created < now() 
     and created > concat(curdate(),' 4:30:00 AM') 

At first glance, your code will not compile. Since the nested if statement doesn't have any braces, it will consider the next line the code that it should execute. Also, you are comparing a char against a String, " ". Try comparing the values as chars instead. I think the correct syntax would be:

if(c == ' '){
   //do something here
}

But then again, I am not familiar with the "Equal" class

Trying to access an undefined variable will throw you a ReferenceError.

A solution to this is to use typeof:

if (typeof window === "undefined") {
  console.log("Oops, `window` is not defined")
}

or a try catch:

try { window } catch (err) {
  console.log("Oops, `window` is not defined")
}

While typeof window is probably the cleanest of the two, the try catch can still be useful in some cases.

The right approach is to use setImageViewUri() (slower) or the setImageViewBitmap() and recreating RemoteViews every time you update the notification.

Try css:

.topcorner{
    position:absolute;
    top:10px;
    right: 10px;
 }

you can play with the top and right properties.

If you want to float the div even when you scroll down, just change position:absolute; to position:fixed;.

Hope it helps.

You can use Java 8 Stream API.

Method distinct is an intermediate operation that filters the stream and allows only distinct values (by default using the Object::equals method) to pass to the next operation.
I wrote an example below for your case,

// Create the list with duplicates.
List<String> listAll = Arrays.asList("CO2", "CH4", "SO2", "CO2", "CH4", "SO2", "CO2", "CH4", "SO2");

// Create a list with the distinct elements using stream.
List<String> listDistinct = listAll.stream().distinct().collect(Collectors.toList());

// Display them to terminal using stream::collect with a build in Collector.
String collectAll = listAll.stream().collect(Collectors.joining(", "));
System.out.println(collectAll); //=> CO2, CH4, SO2, CO2, CH4 etc..
String collectDistinct = listDistinct.stream().collect(Collectors.joining(", "));
System.out.println(collectDistinct); //=> CO2, CH4, SO2

In fact, unsigned int on most modern processors (ARM, Intel/AMD, Alpha, SPARC, Itanium ,PowerPC) will have a range of 0 to 2^32 - 1 which is 4,294,967,295 = 0xffffffff because int (both signed and unsigned) will be 32 bits long and the largest one is as stated.

(unsigned short will have maximal value 2^16 - 1 = 65,535 )

(unsigned) long long int will have a length of 64 bits (long int will be enough under most 64 bit Linuxes, etc, but the standard promises 64 bits for long long int). Hence these have the range 0 to 2^64 - 1 = 18446744073709551615

My freely available memory profiler MemPro allows you to compare 2 snapshots and gives stack traces for all of the allocations.

Take a look at the border-collapse: separate attribute (default) and the border-spacing property.

First, you have to seperate them with border-collapse, then you can define the space between columns and rows with border-spacing .

Both of these CSS properties are actually well-supported on every browser, see here.

table     {border-collapse: separate;  border-spacing: 10px 20px;}_x000D_
_x000D_
table, _x000D_
table td,_x000D_
table th  {border: 1px solid black;}

<table>_x000D_
  <tr>_x000D_
    <td>Some text - 1</td>_x000D_
    <td>Some text - 1</td>_x000D_
  </tr>_x000D_

Just add date keyword. E.g. select date(orderdate),count(1) from orders where orderdate > '2014-10-01' group by date(orderdate);

orderdate is in date time. This query will show the orders for that date rather than datetime.

Date keyword applied on a datetime column will change it to short date.

First Talk About

Normal Class - that's mean any class define that's a normally in java it's means you create different type of method properties etc.
Bean - Bean is nothing it's only a object of that particular class using this bean you can access your java class same as object..

and after that talk about last one POJO

POJO - POJO is that class which have no any services it's have only a default constructor and private property and those property for setting a value corresponding setter and getter methods. It's short form of Plain Java Object.

If you are using pandas and have lots of RAM (enough to read the whole file into memory) try using pd.read_csv with low_memory=False, e.g.:

import pandas as pd
data = pd.read_csv('file.csv', low_memory=False)

If you have multiple occurrences of an element name, then you have to use forEach().

html

  <input type="checkbox" name="delete" id="flizzit" />
  <input type="checkbox" name="delete" id="floo" />
  <input type="checkbox" name="delete" id="flum" />
  <input type="submit" value="Save"  onClick={evt => saveAction(evt)}></input>

js

const submitAction = (evt) => {
  evt.preventDefault();
  const dels = evt.target.parentElement.delete;
  const deleted = [];
  dels.forEach((d) => { if (d.checked) deleted.push(d.id); });
  window.alert(deleted.length);
};

Note the dels in this case is a RadioNodeList, not an array, and is not an Iterable. The forEach()is a built-in method of the list class. You will not be able to use a map() or reduce() here.

Here is what worked for me on a mm/dd/yyyy format:

=DATE(VALUE(RIGHT(A1,4)),VALUE(LEFT(A1,2)),VALUE(MID(A1,4,2)))

Convert the cell with the formula to date format and drag the formula down.

I just posted an answer on a thread similiar to this here https://stackoverflow.com/a/43357241/3958617

The approach with:

<a href="whatsapp://send?abid=username&text=Hello%2C%20World!">whatsapp</a>

and with

<a href="intent://send/0123456789#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end">whatsapp</a>

Only works if the person who clicked on your link have your number on their contact list.

Since not everybody will have it, the other solution is to use Whatsapp API like this:

<a href="https://api.whatsapp.com/send?phone=15551234567">Send Message</a>

• More details on this API here: https://www.whatsapp.com/faq/en/general/26000030

• And observations on how to use it here: https://stackoverflow.com/a/43357241/3958617

Long answer to short, if you install boost in custom path, all header files must in ${path}/boost/.

if you want to konw why cmake can't find the requested Boost libraries after you have set BOOST_ROOT/BOOST_INCLUDEDIR, you can check cmake install location path_to_cmake/share/cmake-xxx/Modules/FindBoost.

cmake which will find Boost_INCLUDE_DIR in boost/config.hpp in BOOST_ROOT. That means your boost header file must in ${path}/boost/, any other format (such as ${path}/boost-x.y.z) will not be suitable for find_package in CMakeLists.txt.

this is pretty useful:

https://github.com/JedWatson/classnames

You can do stuff like

classNames('foo', 'bar'); // => 'foo bar'
classNames('foo', { bar: true }); // => 'foo bar'
classNames({ 'foo-bar': true }); // => 'foo-bar'
classNames({ 'foo-bar': false }); // => ''
classNames({ foo: true }, { bar: true }); // => 'foo bar'
classNames({ foo: true, bar: true }); // => 'foo bar'

// lots of arguments of various types
classNames('foo', { bar: true, duck: false }, 'baz', { quux: true }); // => 'foo bar baz quux'

// other falsy values are just ignored
classNames(null, false, 'bar', undefined, 0, 1, { baz: null }, ''); // => 'bar 1'

or use it like this

var btnClass = classNames('btn', this.props.className, {
  'btn-pressed': this.state.isPressed,
  'btn-over': !this.state.isPressed && this.state.isHovered
});

You could use a simple array intersection, this way you can know what differs in each hash.

    hash1 = { a: 1 , b: 2 }
    hash2 = { a: 2 , b: 2 }

    overlapping_elements = hash1.to_a & hash2.to_a

    exclusive_elements_from_hash1 = hash1.to_a - overlapping_elements
    exclusive_elements_from_hash2 = hash2.to_a - overlapping_elements

You can set your cookie value containing expiry and get your expiry from cookie value.

// set
$expiry = time()+3600;
setcookie("mycookie", "mycookievalue|$expiry", $expiry);

// get
if (isset($_COOKIE["mycookie"])) {
  list($value, $expiry) = explode("|", $_COOKIE["mycookie"]);
}

// Remember, some two-way encryption would be more secure in this case. See: https://github.com/qeremy/Cryptee

I usually manually set the port that I am listening on in the app.js file (assuming you are using express.js

var server = app.listen(8080, function() {
    console.log('Ready on port %d', server.address().port);
});

This will log Ready on port 8080 to your console.

First, I see you're using an explicit $.parseJSON(). If that's because you're manually serializing JSON on the server-side, don't. ASP.NET will automatically JSON-serialize your method's return value and jQuery will automatically deserialize it for you too.

To iterate through the first item in the array you've got there, use code like this:

var firstItem = response.d[0];

for(key in firstItem) {
  console.log(key + ':' + firstItem[key]);
}

If there's more than one item (it's hard to tell from that screenshot), then you can loop over response.d and then use this code inside that outer loop.

this will sort it for you

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

    Button but1=(Button)findViewById(R.id.button1);

    but1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            Intent int1= new Intent(MainActivity.this,xxactivity.class);
            startActivity(int1);
        }
    });
}

You just need to amend the xxactivity to the name of your second activity

Yes it works fine and is commonly used:

$ echo "hello world" | mail -s "a subject" [email protected]

This is the class where the connection is established and messages are recieved. Make sure to pair the devices before you run the application. If you want to have a slave/master connection, where each slave can only send messages to the master , and the master can broadcast messages to all slaves. You should only pair the master with each slave , but you shouldn't pair the slaves together.

Your main activity should be as follow :

package com.example.gaby.coordinatorv1;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class MainActivity extends Activity {

    private Button discoveryButton;
    private Button messageButton;

    private Piconet piconet;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        piconet = new Piconet(getApplicationContext());

        messageButton = (Button) findViewById(R.id.messageButton);
        messageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                piconet.bluetoothBroadcastMessage("Hello World---*Gaby Bou Tayeh*");
            }
        });

        discoveryButton = (Button) findViewById(R.id.discoveryButton);
        discoveryButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                piconet.startPiconet();
            }
        });

    }

}

And here's the XML Layout :

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >

<Button
    android:id="@+id/discoveryButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Discover"
    />

<Button
    android:id="@+id/messageButton"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Send message"
    />

Do not forget to add the following permissions to your Manifest File :

    <uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

In this case, you might get some differences. Consider a line like:

"foo\tbar "

In this case, if you strip, then you'll get {"foo":"bar"} as the dictionary entry. If you don't strip, you'll get {"foo":"bar "} (note the extra space at the end)

Note that if you use line.split() instead of line.split('\t'), you'll split on every whitespace character and the "striping" will be done during splitting automatically. In other words:

line.strip().split()

is always identical to:

line.split()

but:

line.strip().split(delimiter)

Is not necessarily equivalent to:

line.split(delimiter)

echo "Enter Drive letter" 
set /p driveletter=

attrib -s -h -a /s /d  %driveletter%:\*.*

Your DateFormat pattern does not match you input date String. You could use

new SimpleDateFormat("dd-MMM-yyyy")

Use the following Statement:

IF EXISTS(SELECT * FROM prueba )
then
  UPDATE prueba
  SET nombre = '1', apellido = '1' 
  WHERE cedula = 'ct'
ELSE 
  INSERT INTO prueba (cedula, nombre, apellido)
  VALUES ('ct', 'ct', 'ct');

$docker-compose build

If there is something new it will be rebuilt.

FYI, from November 2018 anyone who wants access Twitter’s APIs must apply for a Twitter Development Account by visiting https://developer.twitter.com/. Once your application has been approved then only you'll be able to create Twitter apps.

Once the Twitter Developer Account is ready:

1) Go to https://developer.twitter.com/.

2) Click on Apps and then click on Create an app.

3) Provide an App Name & Description.

4) Enter a website name in the Website URL field.

5) Click on Create.

6) Navigate to your app, then click on Details and then go to Keys and Tokens.

The other people made very nice answers, but I would like to complete their work with an extra development tool. It is called Live HTTP Headers and you can install it into your Firefox, and in Chrome we have the same plug in like this.

Working with it is queit easy.

1. Using your Firefox, navigate to the website which you want to get your post request to it.

2. In your Firefox menu Tools->Live Http Headers

3. A new window pop ups for you, and all the http method details would be saved in this window for you. You don't need to do anything in this step.

4. In the website, do an activity(log in, submit a form, etc.)

5. Look at your plug in window. It is all recorded.

Just remember you need to check the Capture.

If you have changed the model and database with tables that already exist, and you receive the error "Model backing a DB Context has changed; Consider Code First Migrations" you should:

• Delete the files under "Migration" folder in your project
• Open Package Manager console and run pm>update-database -Verbose

Just put the labels in a div inside the TD and put the height and overflow.. like below.

<table>
<tr>
  <td><div style="height:40px; overflow:hidden">Sample</div></td>
  <td><div style="height:40px; overflow:hidden">Text</div></td>
  <td><div style="height:40px; overflow:hidden">Here</div></td>
</tr>
</table>

The universal adb driver installer worked for me. I went from an HTC to a Samsung to a LG Nexus. The drivers are all over the place for me.

http://adbdriver.com/

Compile with debug information:

gcc -g -o main main.c

Separate the debug information:

objcopy --only-keep-debug main main.debug

or

cp main main.debug
strip --only-keep-debug main.debug

Strip debug information from origin file:

objcopy --strip-debug main

or

strip --strip-debug --strip-unneeded main

debug by debuglink mode:

objcopy --add-gnu-debuglink main.debug main
gdb main

You can also use exec file and symbol file separatly:

gdb -s main.debug -e main

or

gdb
(gdb) exec-file main
(gdb) symbol-file main.debug

For details:

(gdb) help exec-file
(gdb) help symbol-file

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

Here is a working fiddle with indeterminate number of cells: http://jsfiddle.net/r9yrM/1/

You can fix a width to each parent div (the table), otherwise it'll be 100% as usual.

The trick is to use table-layout: fixed; and some width on each cell to trigger it, here 2%. That will trigger the other table algorightm, the one where browsers try very hard to respect the dimensions indicated.
Please test with Chrome (and IE8- if needed). It's OK with a recent Safari but I can't remember the compatibility of this trick with them.

CSS (relevant instructions):

div {
    display: table;
    width: 250px;
    table-layout: fixed;
}

div > div {
    display: table-cell;
    width: 2%; /* or 100% according to OP comment. See edit about Safari 6 below */
}

EDIT (2013): Beware of Safari 6 on OS X, it has table-layout: fixed; wrong (or maybe just different, very different from other browsers. I didn't proof-read CSS2.1 REC table layout ;) ). Be prepared to different results.

Exception#backtrace has the entire stack in it:

def do_division_by_zero; 5 / 0; end
begin
  do_division_by_zero
rescue => exception
  puts exception.backtrace
  raise # always reraise
end

(Inspired by Peter Cooper's Ruby Inside blog)

Now that Chrome 18 was released last week with the required APIs, I published my chrome extension in the Chrome web store. The extension automatically saves changes in CSS or JS in Developer tools into the local disk. Go check it out.

To convert int32 to string in mongo without creating an array just add "" to your number :-)

db.foo.find( { 'mynum' : { $type : 16 } } ).forEach( function (x) {   
  x.mynum = x.mynum + ""; // convert int32 to string
  db.foo.save(x);
});

In your example propertyInfo.GetValue(this, null) should work. Consider altering GetNamesAndTypesAndValues() as follows:

public void GetNamesAndTypesAndValues()
{
  foreach (PropertyInfo propertyInfo in allClassProperties)
  {
    Console.WriteLine("{0} [type = {1}] [value = {2}]",
      propertyInfo.Name,
      propertyInfo.PropertyType,
      propertyInfo.GetValue(this, null));
  }
}

Regular javascript can be used to trap the backspace key. You can use the event.keyCode method. The keycode is 8, so the code would look something like this:

if (event.keyCode == 8) {
    // Do stuff...
}

If you want to check for both the [delete] (46) as well as the [backspace] (8) keys, use the following:

if (event.keyCode == 8 || event.keyCode == 46) {
    // Do stuff...
}

What you're doing is 100% correct.

In terms of nice naming it's often done that private/protected properties are preceded with an underscore to make it obvious that they're not public. E.g. private $_arr = array() or public $arr = array()

It is only possible as from C# 4.0

However, when you use a version of C#, prior to 4.0, you can work around this by using overloaded methods:

public void Func( int i, int j )
{
    Console.WriteLine (String.Format ("i = {0}, j = {1}", i, j));
}

public void Func( int i )
{
    Func (i, 4);
}

public void Func ()
{
    Func (5);
}

(Or, you can upgrade to C# 4.0 offcourse).

Another no-regex solution that works well on Python 3

# Split strings and keep separator
test_strings = ['<Hello>', 'Hi', '<Hi> <Planet>', '<', '']

def split_and_keep(s, sep):
   if not s: return [''] # consistent with string.split()

   # Find replacement character that is not used in string
   # i.e. just use the highest available character plus one
   # Note: This fails if ord(max(s)) = 0x10FFFF (ValueError)
   p=chr(ord(max(s))+1) 

   return s.replace(sep, sep+p).split(p)

for s in test_strings:
   print(split_and_keep(s, '<'))


# If the unicode limit is reached it will fail explicitly
unicode_max_char = chr(1114111)
ridiculous_string = '<Hello>'+unicode_max_char+'<World>'
print(split_and_keep(ridiculous_string, '<'))

Use the appropriate methods in Scripting.FileSystemObject. Then your code will be more portable to VBScript and VB.net. To get you started, you'll need to include:

Dim fso As Object
Set fso = VBA.CreateObject("Scripting.FileSystemObject")

Then you could use

Call fso.CopyFile(source, destination[, overwrite] )

where source and destination are the full names (including paths) of the file.

See https://docs.microsoft.com/en-us/office/vba/Language/Reference/user-interface-help/copyfile-method

You can check if the Connected property is set to $true and display a friendly message:

    $t = New-Object Net.Sockets.TcpClient "10.45.23.109", 443 

    if($t.Connected)
    {
        "Port 443 is operational"
    }
    else
    {
        "..."
    }

The number of distinct words (i.e. count of entries in the dictionary) can be found using the len() function.

> a = {'foo':42, 'bar':69}
> len(a)
2

To get all the distinct words (i.e. the keys), use the .keys() method.

> list(a.keys())
['foo', 'bar']

Thank you LSerni you solved it for me.

To achieve this :

+-----------------------------------------+
| +-------+                     +-------+ |
| | Text1 |                     | Text1 | |
| +-------+                     +-------+ |
|+----------------------------------------+

You have to do this :

<div style="overflow:auto">
    <div style="display:inline-block;float:left"> Text1 </div>
    <div style="display:inline-block;float:right"> Text2 </div>
</div>

Use the RAISERROR function:

RAISERROR( 'This message will show up right away...',0,1) WITH NOWAIT

You shouldn't completely replace all your prints with raiserror. If you have a loop or large cursor somewhere just do it once or twice per iteration or even just every several iterations.

Also: I first learned about RAISERROR at this link, which I now consider the definitive source on SQL Server Error handling and definitely worth a read:
http://www.sommarskog.se/error-handling-I.html

I'd try this:

Split your Model into a separate file called model.ts:

export class Model {
    param1: string;
}

Import it into your component. This will give you the added benefit of being able to use it in other components:

Import { Model } from './model';

Initialize in the component:

export class testWidget {
   public model: Model;
   constructor(){
       this.model = new Model();
       this.model.param1 = "your string value here";
   }
}

Access it appropriately in the html:

@Component({
      selector: "testWidget",
      template: "<div>This is a test and {{model.param1}} is my param.</div>"
})

I want to add to the answer a comment made by @PatMigliaccio because it's important to adapt to the latest tools and technologies:

If you are using angular-cli you can call ng g class model and it will generate it for you. model being replaced with whatever naming you desire.

You can place a TEXTAREA of similar size under your DIV, so the standard control's frame would be visible around div.

It's probably good to set it to be disabled, to prevent accidental focus stealing.

You call tarfile.open with mode='w:gz', meaning "Open for gzip compressed writing."

You'll probably want to end the filename (the name argument to open) with .tar.gz, but that doesn't affect compression abilities.

BTW, you usually get better compression with a mode of 'w:bz2', just like tar can usually compress even better with bzip2 than it can compress with gzip.

You can call a stored procedure from another stored procedure by using the EXECUTE command.

Say your procedure is X. Then in X you can use

EXECUTE PROCEDURE Y () RETURNING_VALUES RESULT;"

If it's not a literal, you have to use \\\\ so that you get \\ which means an escaped backslash.

That's because there are two representations. In the string representation of your regex, you have "\\\\", Which is what gets sent to the parser. The parser will see \\ which it interprets as a valid escaped-backslash (which matches a single backslash).

If you're on a Windows machine, View the repository through a browser and you may well see two files with the same filename but using different cases. Subversion is case sensitive and Windows isn't so you can get a lock when Windows thinks it's pulling down the same file and Subversion doesn't. Delete the duplicate file names on the repository and try again.

Here's a modification of Lyth's answer that takes into account:

• Deletion
• Initialisation
• Placeholders

It also allows for any number of input fields! To see it in action: http://jsfiddle.net/4Qsa8/

        var $this = $(this);
        if (!text.trim()) {
            text = $this.attr('placeholder').trim();
        }
        var $span = $this.parent().find('span');
        $span.text(text);
        var $inputSize = $span.width();
        $this.css("width", $inputSize);

You can use ISNULL:

ISNULL(field, VALUEINCASEOFNULL)

You can also use @media queries to establish your max/min padding/margin (but only according to screen size):

Let's say you want a max padding of 8px, you can do the following

div {
  padding: 1vh 0;
}
@media (max-height: 800px) {
  div {
    padding: 8px 0;
  }
}

If you use UTF-8 encoding then one character can takes a various number of bytes (2 - 4). For PL/SQL the varchar2 limit is 32767 bytes, not characters. See how I increase a PL/SQL varchar2 variable of the 4000 character size:

SQL> set serveroutput on
SQL> l
  1  declare
  2    l_var varchar2(30000);
  3  begin
  4    l_var := rpad('A', 4000);
  5    dbms_output.put_line(length(l_var));
  6    l_var := l_var || rpad('B', 10000);
  7    dbms_output.put_line(length(l_var));
  8* end;
SQL> /
4000
14000

PL/SQL procedure successfully completed.

But you can't insert into your table the value of such variable:

SQL> ed
Wrote file afiedt.buf

  1  create table ttt (
  2    col1 varchar2(2000 char)
  3* )
SQL> /

Table created.

SQL> ed

  1  declare
  2    l_var varchar2(30000);
  3  begin
  4      l_var := rpad('A', 4000);
  5      dbms_output.put_line(length(l_var));
  6      l_var := l_var || rpad('B', 10000);
  7      dbms_output.put_line(length(l_var));
  8      insert into ttt values (l_var);
  9* end;
SQL> /
4000
14000
declare
*
ERROR at line 1:
ORA-01461: can bind a LONG value only for insert into a LONG column
ORA-06512: at line 8

As a solution, you can try to split this variable's value into several parts (SUBSTR) and store them separately.

Adding to what @sateesh said, when you just want to mock a void method in order to prevent the test from calling it, you could use a Spy this way:

World world = new World();
World spy = Mockito.spy(world);
Mockito.doNothing().when(spy).methodToMock();

When you want to run your test, make sure you call the method in test on the spy object and not on the world object. For example:

assertEquals(0, spy.methodToTestThatShouldReturnZero());

<style name="captionOnly">
    <item name="android:background">@null</item>
    <item name="android:clickable">false</item>
    <item name="android:focusable">false</item>
    <item name="android:minHeight">0dp</item>
    <item name="android:minWidth">0dp</item>
</style>

<FrameLayout
   style="?android:attr/buttonStyle"
   android:layout_width="match_parent"
   android:layout_height="wrap_content" >

    <Button
       style="@style/captionOnly"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_gravity="center"
       android:drawableLeft="@android:drawable/ic_delete"
       android:gravity="center"
       android:text="Button Challenge" />
</FrameLayout>

Put the FrameLayout in LinearLayout and set orientation to Horizontal.

Uncaught exception messages go to STDERR, so instead of implementing your logging in Python itself you could send STDERR to a file using whatever shell you're using to run your Python script. In a Bash script, you can do this with output redirection, as described in the BASH guide.

Examples

Append errors to file, other output to the terminal:

./test.py 2>> mylog.log

Overwrite file with interleaved STDOUT and STDERR output:

./test.py &> mylog.log

The simplest solution would be open terminal

$ java -version

it shows the following

java version "1.6.0_65"

2. Stefan's solution also works for me. Here's the exact input:

$ cd /System/Library/Frameworks/JavaVM.framework/Versions

$ ls -l

Below is the last line of output:

lrwxr-xr-x   1 root  wheel   59 Feb 12 14:57 CurrentJDK -> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents

1.6.0.jdk would be the answer

Using try except and the right error code from errno module gets rid of the race condition and is cross-platform:

import os
import errno

def make_sure_path_exists(path):
    try:
        os.makedirs(path)
    except OSError as exception:
        if exception.errno != errno.EEXIST:
            raise

In other words, we try to create the directories, but if they already exist we ignore the error. On the other hand, any other error gets reported. For example, if you create dir 'a' beforehand and remove all permissions from it, you will get an OSError raised with errno.EACCES (Permission denied, error 13).

As of my understanding Partition By is almost identical to Group By, but with the following differences:

That group by actually groups the result set returning one row per group, which results therefore in SQL Server only allowing in the SELECT list aggregate functions or columns that are part of the group by clause (in which case SQL Server can guarantee that there are unique results for each group).

Consider for example MySQL which allows to have in the SELECT list columns that are not defined in the Group By clause, in which case one row is still being returned per group, however if the column doesn't have unique results then there is no guarantee what will be the output!

But with Partition By, although the results of the function are identical to the results of an aggregate function with Group By, still you are getting the normal result set, which means that one is getting one row per underlying row, and not one row per group, and because of this one can have columns that are not unique per group in the SELECT list.

So as a summary, Group By would be best when needs an output of one row per group, and Partition By would be best when one needs all the rows but still wants the aggregate function based on a group.

Of course there might also be performance issues, see http://social.msdn.microsoft.com/Forums/ms-MY/transactsql/thread/0b20c2b5-1607-40bc-b7a7-0c60a2a55fba.

Of course there is! Win CMD can do a lot more than just split text files :)

Split a text file into separate files of 'max' lines each:

Split text file (max lines each):
: Initialize
set input=file.txt
set max=10000

set /a line=1 >nul
set /a file=1 >nul
set out=!file!_%input%
set /a max+=1 >nul

echo Number of lines in %input%:
find /c /v "" < %input%

: Split file
for /f "tokens=* delims=[" %i in ('type "%input%" ^| find /v /n ""') do (

if !line!==%max% (
set /a line=1 >nul
set /a file+=1 >nul
set out=!file!_%input%
echo Writing file: !out!
)

REM Write next file
set a=%i
set a=!a:*]=]!
echo:!a:~1!>>out!
set /a line+=1 >nul
)

If above code hangs or crashes, this example code splits files faster (by writing data to intermediate files instead of keeping everything in memory):

eg. To split a file with 7,600 lines into smaller files of maximum 3000 lines.

1. Generate regexp string/pattern files with set command to be fed to /g flag of findstr

list1.txt

\[[0-9]\]
\[[0-9][0-9]\]
\[[0-9][0-9][0-9]\]
\[[0-2][0-9][0-9][0-9]\]

list2.txt

\[[3-5][0-9][0-9][0-9]\]

list3.txt

\[[6-9][0-9][0-9][0-9]\]

2. Split the file into smaller files:

type "%input%" | find /v /n "" | findstr /b /r /g:list1.txt > file1.txt
type "%input%" | find /v /n "" | findstr /b /r /g:list2.txt > file2.txt
type "%input%" | find /v /n "" | findstr /b /r /g:list3.txt > file3.txt

3. remove prefixed line numbers for each file split:
   eg. for the 1st file:

for /f "tokens=* delims=[" %i in ('type "%cd%\file1.txt"') do (
set a=%i
set a=!a:*]=]!
echo:!a:~1!>>file_1.txt)

Notes:
Works with leading whitespace, blank lines & whitespace lines.

Tested on Win 10 x64 CMD, on 4.4GB text file, 5651982 lines.

One method I can think of is this:

1) Let the UI bind to the service.
2) Expose a method like the one below by the Binder that registers your Handler:

public void registerHandler(Handler handler) {
    mHandler = handler;
}

3) In the UI thread, call the above method after binding to the service:

mBinder.registerHandler(new Handler());

4) Use the handler in the Service's thread to post your task:

mHandler.post(runnable);

on os x these are the same for me... could this maybe be extra "\r" in windows?

in any case you may be better of with:

contents = File.read("e.tgz")
newFile = File.open("ee.tgz", "w")
newFile.write(contents)

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

I just use this for add a image to clipboard in windows.

If you only want to checkout and you delete the folder from the workspace you also need to delete the reference to it in the Java view. Then it should checkout as if it were checking out for the first time.

Even though this question is old, I'll quickly mention that I've thrown together an ActionSheetPicker class with a convenience function, so you can spawn an ActionSheet with a UIPickerView in one line. It's based on code from answers to this question.

Edit: It now also supports the use of a DatePicker and DistancePicker.

UPD:

This version is deprecated: use ActionSheetPicker-3.0 instead.

There are 2 options you can go with HTTP URL Hits : GET / POST

GET Request :-

HttpURLConnection.setFollowRedirects(true); // defaults to true

String url = "https://name_of_the_url";
URL request_url = new URL(url);
HttpURLConnection http_conn = (HttpURLConnection)request_url.openConnection();
http_conn.setConnectTimeout(100000);
http_conn.setReadTimeout(100000);
http_conn.setInstanceFollowRedirects(true);
System.out.println(String.valueOf(http_conn.getResponseCode()));

POST request :-

HttpURLConnection.setFollowRedirects(true); // defaults to true

String url = "https://name_of_the_url"
URL request_url = new URL(url);
HttpURLConnection http_conn = (HttpURLConnection)request_url.openConnection();
http_conn.setConnectTimeout(100000);
http_conn.setReadTimeout(100000);
http_conn.setInstanceFollowRedirects(true);
http_conn.setDoOutput(true);
PrintWriter out = new PrintWriter(http_conn.getOutputStream());
if (urlparameter != null) {
   out.println(urlparameter);
}
out.close();
out = null;
System.out.println(String.valueOf(http_conn.getResponseCode()));

You need to do a LEFT JOIN.

SELECT Computer.ComputerName, Application.Name, Software.Version
FROM Computer
JOIN dbo.Software_Computer
    ON Computer.ID = Software_Computer.ComputerID
LEFT JOIN dbo.Software
    ON Software_Computer.SoftwareID = Software.ID
RIGHT JOIN dbo.Application
    ON Application.ID = Software.ApplicationID
WHERE Computer.ID = 1 

Here is the explanation:

The result of a left outer join (or simply left join) for table A and B always contains all records of the "left" table (A), even if the join-condition does not find any matching record in the "right" table (B). This means that if the ON clause matches 0 (zero) records in B, the join will still return a row in the result—but with NULL in each column from B. This means that a left outer join returns all the values from the left table, plus matched values from the right table (or NULL in case of no matching join predicate). If the right table returns one row and the left table returns more than one matching row for it, the values in the right table will be repeated for each distinct row on the left table. From Oracle 9i onwards the LEFT OUTER JOIN statement can be used as well as (+).

This might be trivial and not related to the OP's question, but I often made this mistaken at the beginning when I was learning scripting

VAR_NAME = $(hostname)
echo "the hostname is ${VAR_NAME}"  

This will produce 'command not found' response. The correct way is to eliminate the spaces

VAR_NAME=$(hostname)

Using PyParsing

import pyparsing as pp

word = pp.Word(pp.alphanums)

s = 'gfgfdAAA1234ZZZuijjk'
rule = pp.nestedExpr('AAA', 'ZZZ')
for match in rule.searchString(s):
    print(match)

which yields:

[['1234']]

Working with predicate for pretty long time. Here is my conclusion (SWIFT)

//Customizable! (for me was just important if at least one)
request.fetchLimit = 1


//IF IS EQUAL

//1 OBJECT
request.predicate = NSPredicate(format: "name = %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name = %@ AND nickName = %@", argumentArray: [name, nickname])


// IF CONTAINS

//1 OBJECT
request.predicate = NSPredicate(format: "name contains[c] %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name contains[c] %@ AND nickName contains[c] %@", argumentArray: [name, nickname])

The reason why your attempt didn't work out is, that you have used a class-selector, which returns a collection of elements, not an (=one!) element, which you need to access the players properties and methods. To make it work there's basically three ways, which have been mentioned, but just for an overview:

Get the element – not a collection – by...

• Iterating over the colllection and fetching the element with this (like in the accepted answer).

• Using an id-selector, if available.

• Getting the element of a collection, by fetching it, via its position in the collection by appending [0] to the selector, which returns the first element of the collection.

Adding here my experience that hopefully might help somebody.

I was experiencing the same issue on Android emulator in Linux with hot reload. The code was correct as per accepted answer and the emulator could reach the internet (I needed a domain name).

Refreshing manually the app made it work. So maybe it has something to do with the hot reloading.

Although it's not really clear to me what you're trying to achieve, I spotted an obvious error in your code: Field.get() expects the object which contains the field as argument, not some (possible) value of that field. So you should have field.get(object).

Since you appear to be looking for the field value, you can obtain that as:

Object objectValue = field.get(object);

No need to instantiate the field type and create some empty/default value; or maybe there's something I missed.

Use the .str()-method:

Manages the contents of the underlying string object.

1) Returns a copy of the underlying string as if by calling rdbuf()->str().

2) Replaces the contents of the underlying string as if by calling rdbuf()->str(new_str)...

Notes

The copy of the underlying string returned by str is a temporary object that will be destructed at the end of the expression, so directly calling c_str() on the result of str() (for example in auto *ptr = out.str().c_str();) results in a dangling pointer...

Add a parameter of type UriComponentsBuilder to your controller method. Spring will give you an instance that's preconfigured with the URI for the current request, and you can then customize it (such as by using MvcUriComponentsBuilder.relativeTo to point at a different controller using the same prefix).

If you want to exit from your application. Then use this code inside your button pressed event. like:

public void onBackPressed()
{
    moveTaskToBack(true);
    android.os.Process.killProcess(android.os.Process.myPid());
    System.exit(1);
}

private void Form1_Load(object sender, EventArgs e)
    {
        PictureBox pb = new PictureBox();
        pb.Location = new Point(0, 0);
        pb.Size = new Size(150, 150);
        pb.Image = Image.FromFile("E:\\Wallpaper (204).jpg");
        pb.Visible = true;
        this.Controls.Add(pb);
    }

Convert the number into a string, match the number up to the second decimal place:

function calc(theform) {_x000D_
    var num = theform.original.value, rounded = theform.rounded_x000D_
    var with2Decimals = num.toString().match(/^-?\d+(?:\.\d{0,2})?/)[0]_x000D_
    rounded.value = with2Decimals_x000D_
}

<form onsubmit="return calc(this)">_x000D_
Original number: <input name="original" type="text" onkeyup="calc(form)" onchange="calc(form)" />_x000D_
<br />"Rounded" number: <input name="rounded" type="text" placeholder="readonly" readonly>_x000D_
</form>

The toFixed method fails in some cases unlike toString, so be very careful with it.

To top up on @Tim Schmelter, in which to get back the List<int> instead,

List<string> selectedValues = CBLGold.Items.Cast<ListItem>()
   .Where(li => li.Selected)
   .Select(li => li.Value)
   .Select(int.Parse)
   .ToList();

It's impossible. You can only find and access views that are currently running. If you want to check the value of ex. TextView used in previus activity you must save the value is SharedPreferences, database, file or pass by Intent.

You can use the mixin make-col-ready and set the gutter width to zero:

@include make-col-ready(0);

Agreed with Yuri Tkachenko's answer.

I wanna point this out.

It's a pretty specific scenario. BUT it happens.

When you copy a gif before its loaded fully in some site like google images. it just gives the preview image address of that gif. Which is clearly not a gif.

So, make sure it ends with .gif extension

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

This is a question about scope.

If you only want the variables to last the lifetime of the function, use Dim (short for Dimension) inside the function or sub to declare the variables:

Function AddSomeNumbers() As Integer
    Dim intA As Integer
    Dim intB As Integer
    intA = 2
    intB = 3
    AddSomeNumbers = intA + intB
End Function
'intA and intB are no longer available since the function ended

A global variable (as SLaks pointed out) is declared outside of the function using the Public keyword. This variable will be available during the life of your running application. In the case of Excel, this means the variables will be available as long as that particular Excel workbook is open.

Public intA As Integer
Private intB As Integer

Function AddSomeNumbers() As Integer
    intA = 2
    intB = 3
    AddSomeNumbers = intA + intB
End Function
'intA and intB are still both available.  However, because intA is public,  '
'it can also be referenced from code in other modules. Because intB is private,'
'it will be hidden from other modules.

You can also have variables that are only accessible within a particular module (or class) by declaring them with the Private keyword.

If you're building a big application and feel a need to use global variables, I would recommend creating a separate module just for your global variables. This should help you keep track of them in one place.

Quoting the spec

15.4 Array Objects

Array objects give special treatment to a certain class of property names. A property name P (in the form of a String value) is an array index if and only if ToString(ToUint32(P)) is equal to P and ToUint32(P) is not equal to 2^32-1. A property whose property name is an array index is also called an element. Every Array object has a length property whose value is always a nonnegative integer less than 2^32. The value of the length property is numerically greater than the name of every property whose name is an array index; whenever a property of an Array object is created or changed, other properties are adjusted as necessary to maintain this invariant. Specifically, whenever a property is added whose name is an array index, the length property is changed, if necessary, to be one more than the numeric value of that array index; and whenever the length property is changed, every property whose name is an array index whose value is not smaller than the new length is automatically deleted. This constraint applies only to own properties of an Array object and is unaffected by length or array index properties that may be inherited from its prototypes.

And here's a table for typeof

To add some background, there are two data types in JavaScript:

1. Primitive Data types - This includes null, undefined, string, boolean, number and object.
2. Derived data types/Special Objects - These include functions, arrays and regular expressions. And yes, these are all derived from "Object" in JavaScript.

An object in JavaScript is similar in structure to the associative array/dictionary seen in most object oriented languages - i.e., it has a set of key-value pairs.

An array can be considered to be an object with the following properties/keys:

1. Length - This can be 0 or above (non-negative).
2. The array indices. By this, I mean "0", "1", "2", etc are all properties of array object.

Hope this helped shed more light on why typeof Array returns an object. Cheers!

For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)

  $url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

In Java 8:

Customer findCustomerByid(int id) {
    return this.customers.stream()
        .filter(customer -> customer.getId().equals(id))
        .findFirst().get();
}

It might also be better to change the return type to Optional<Customer>.

What I did was download my sql dump in a "db-dump" folder, and mounted it:

mysql:
 image: mysql:5.6
 environment:
   MYSQL_ROOT_PASSWORD: pass
 ports:
   - 3306:3306
 volumes:
   - ./db-dump:/docker-entrypoint-initdb.d

When I run docker-compose up for the first time, the dump is restored in the db.

You have 4 columns A,B,C,D

Here is a better way to select the columns you need for the new dataframe:-

df2 = df1[['A','D']]

if you wish to use column numbers instead, use:-

df2 = df1[[0,3]]

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

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

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

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

When converting datetime to integers one must keep in mind the tens, hundreds and thousands.... like "2018-11-03" must be like 20181103 in int for that you have to 2018*10000 + 100* 11 + 3

Similarly another example, "2018-11-03 10:02:05" must be like 20181103100205 in int

Explanatory Code

dt = datetime(2018,11,3,10,2,5)
print (dt)

#print (dt.timestamp()) # unix representation ... not useful when converting to int

print (dt.strftime("%Y-%m-%d"))
print (dt.year*10000 + dt.month* 100  + dt.day)
print (int(dt.strftime("%Y%m%d")))

print (dt.strftime("%Y-%m-%d %H:%M:%S"))
print (dt.year*10000000000 + dt.month* 100000000 +dt.day * 1000000 + dt.hour*10000  +  dt.minute*100 + dt.second)
print (int(dt.strftime("%Y%m%d%H%M%S")))

General Function

To avoid that doing manually use below function

def datetime_to_int(dt):
    return int(dt.strftime("%Y%m%d%H%M%S"))

I find it best to just put the default value in the constructor method of the model.

Gender = "Male";

Use a shell script:

#!/bin/bash
# myscript
FOO=bar
somecommand someargs | somecommand2

> ./myscript

I think this does a good job of explaining.

The following is a UNION query that uses an ORDER BY clause:

select supplier_id, supplier_name
from suppliers
where supplier_id > 2000
UNION
select company_id, company_name
from companies
where company_id > 1000
ORDER BY 2;

Since the column names are different between the two "select" statements, it is more advantageous to reference the columns in the ORDER BY clause by their position in the result set.

In this example, we've sorted the results by supplier_name / company_name in ascending order, as denoted by the "ORDER BY 2".

The supplier_name / company_name fields are in position #2 in the result set.

I agree that the best way is to use the one given by: David Chase, Cu Ly, and others that the simplest way to do this is to use the container: $(this) property as follows:

$(selectorString).each(function () {
  var $this = $(this);
  $this.popover({
    html: true,
    placement: "top",
    container: $this,
    trigger: "hover",
    title: "Popover",
    content: "Hey, you hovered on element"

I want to point out here that the popover in this case will inherit all properties of the current element. So, for example, if you do this for a .btn element(bootstrap), you won't be able to select text inside the popover. Just wanted to record that since I spent quite some time banging my head on this.

It's not jquery you need, it's JS:

alert(str.length);

Well, It's quite easy.

Open your local project.

Add a README.md file (If you don't have anything to add yet)

Click on Publish on Github

Choose as you wish

Choose the files you want to include in firt commit.
Note: If you don't select a file or folder it will added to .gitignore file

You are good to go. it is published.

P.S. If this was you first time. A prompt will ask for for your Github Credentials fill those and you are good to go. It is published.

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

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

There is an "auth" parameter for Basic Auth:

auth: {
  username: 'janedoe',
  password: 's00pers3cret'
}

Source/Docs: https://github.com/mzabriskie/axios

Example:

await axios.post(session_url, {}, {
  auth: {
    username: uname,
    password: pass
  }
});

It is possible to get a web application running in full screen in both iOS and Android, it is called a PWA and after mucha hard work, it was the only way around this issue.

PWAs open a number of interesting options for development that should not be missed. I've made a couple already, check out this Public and Private Tender Manual For Designers (Spanish). And here is an English explanation from the CosmicJS site

To get last record from your table..

 String selectQuery = "SELECT  * FROM " + "sqlite_sequence";
 Cursor cursor = db.rawQuery(selectQuery, null);
  cursor.moveToLast();

The traditional method for checking for packages in Python is "it's better to beg forgiveness than ask permission", or rather, "it's better to catch an exception than test a condition."

try:
    import numpy
    HAS_NUMPY = True
except ImportError:
    HAS_NUMPY = False

In java-8, they introduced the method removeIf which takes a Predicate as parameter.

So it will be easy as:

List<String> list = new ArrayList<>(Arrays.asList("How are you",
                                                  "How you doing",
                                                  "Joe",
                                                  "Mike"));
list.removeIf(s -> !s.contains("How"));

Can try this too, almost similar previous answers.

    d = {'filename': ['M66_MI_NSRh35d32kpoints.dat', 'F71_sMI_DMRI51d.dat', 'F62_sMI_St22d7.dat', 'F41_Car_HOC498d.dat', 'F78_MI_547d.dat'], 'alpha1': [0.8016, 0.0, 1.721, 1.167, 1.897], 'alpha2': [0.9283, 0.0, 3.833, 2.809, 5.459], 'gamma1': [1.0, np.nan, 0.23748000000000002, 0.36419, 0.095319], 'gamma2': [0.074804, 0.0, 0.15, 0.3, np.nan], 'chi2min': [39.855990000000006, 1e+25, 10.91832, 7.966335000000001, 25.93468]}
    df = pd.DataFrame(d).set_index('filename')

Count of null values in each column.

df.isnull().sum()

df.isnull().any(axis=1)

You want to convert it to an object first and then access normally making sure to cast it.

JObject obj = JObject.Parse(json);
string name = (string) obj["Name"];

If You are using rvm, then try the following command:

rvmsudo gem install bundler

According to another question: Could not find rails (>= 0) amongst [] (Gem::LoadError)

Hope it helped, Cheers

It's better to use PathVariable annotation if you still want to get the uri which was called.

@PostMapping("/pub/{action:a|b|c}")
public JSONObject handlexxx(@PathVariable String action, @RequestBody String reqStr){
...
}

or parse it from request object.

Now we could also use:

if (Attachment != null  && Attachment.Any())

Any() is often easier to understand in a glance for the developer than checking Length() > 0. Also has very little difference with processing speed.

I use with (nolock) hint particularly in SQLServer 2000 databases with high activity. I am not certain that it is needed in SQL Server 2005 however. I recently added that hint in a SQL Server 2000 at the request of the client's DBA, because he was noticing a lot of SPID record locks.

All I can say is that using the hint has NOT hurt us and appears to have made the locking problem solve itself. The DBA at that particular client basically insisted that we use the hint.

By the way, the databases I deal with are back-ends to enterprise medical claims systems, so we are talking about millions of records and 20+ tables in many joins. I typically add a WITH (nolock) hint for each table in the join (unless it is a derived table, in which case you can't use that particular hint)

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

I used following logic and it worked for me like marvel:

CONVERT(TIME, DATEADD(MINUTE, DATEDIFF(MINUTE, AP.Time_IN, AP.Time_OUT), 0)) 

For SVG elements

Using something like selection.node().getBBox() you get values like

{
    height: 5, 
    width: 5, 
    y: 50, 
    x: 20
} 

For HTML elements

Use selection.node().getBoundingClientRect()

• the simplest way to do that is using encoding/json package

just for example:

package main
import (
    "fmt"
    "encoding/json"
)

type MyAddress struct {
    House string
    School string
}
type Student struct {
    Id int64
    Name string
    Scores float32
    Address MyAddress
    Labels []string
}

func Test() {

    dict := make(map[string]interface{})
    dict["id"] = 201902181425       // int
    dict["name"] = "jackytse"       // string
    dict["scores"] = 123.456        // float
    dict["address"] = map[string]string{"house":"my house", "school":"my school"}   // map
    dict["labels"] = []string{"aries", "warmhearted", "frank"}      // slice

    jsonbody, err := json.Marshal(dict)
    if err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    student := Student{}
    if err := json.Unmarshal(jsonbody, &student); err != nil {
        // do error check
        fmt.Println(err)
        return
    }

    fmt.Printf("%#v\n", student)
}

func main() {
    Test()
}

To convert any object or object list into JSON, we have to use the function JsonConvert.SerializeObject.

The below code demonstrates the use of JSON in an ASP.NET environment:

using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using Newtonsoft.Json;
using System.Collections.Generic;

namespace JSONFromCS
{
    public partial class _Default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e1)
        {
            List<Employee> eList = new List<Employee>();
            Employee e = new Employee();
            e.Name = "Minal";
            e.Age = 24;

            eList.Add(e);

            e = new Employee();
            e.Name = "Santosh";
            e.Age = 24;

            eList.Add(e);

            string ans = JsonConvert.SerializeObject(eList, Formatting.Indented);

            string script = "var employeeList = {\"Employee\": " + ans+"};";
            script += "for(i = 0;i<employeeList.Employee.length;i++)";
            script += "{";
            script += "alert ('Name : ='+employeeList.Employee[i].Name+' 
            Age : = '+employeeList.Employee[i].Age);";
            script += "}";

            ClientScriptManager cs = Page.ClientScript;
            cs.RegisterStartupScript(Page.GetType(), "JSON", script, true);
        }
    }
    public class Employee
    {
        public string Name;
        public int Age;
    }
}  

After running this program, you will get two alerts

In the above example, we have created a list of Employee object and passed it to function "JsonConvert.SerializeObject". This function (JSON library) will convert the object list into JSON format. The actual format of JSON can be viewed in the below code snippet:

{ "Maths" : [ {"Name"     : "Minal",        // First element
                             "Marks"     : 84,
                             "age"       : 23 },
                             {
                             "Name"      : "Santosh",    // Second element
                             "Marks"     : 91,
                             "age"       : 24 }
                           ],                       
              "Science" :  [ 
                             {
                             "Name"      : "Sahoo",     // First Element
                             "Marks"     : 74,
                             "age"       : 27 }, 
                             {                           
                             "Name"      : "Santosh",    // Second Element
                             "Marks"     : 78,
                             "age"       : 41 }
                           ] 
            } 

Syntax:

• {} - acts as 'containers'

• [] - holds arrays

• : - Names and values are separated by a colon

• , - Array elements are separated by commas

This code is meant for intermediate programmers, who want to use C# 2.0 to create JSON and use in ASPX pages.

You can create JSON from JavaScript end, but what would you do to convert the list of object into equivalent JSON string from C#. That's why I have written this article.

In C# 3.5, there is an inbuilt class used to create JSON named JavaScriptSerializer.

The following code demonstrates how to use that class to convert into JSON in C#3.5.

JavaScriptSerializer serializer = new JavaScriptSerializer()
return serializer.Serialize(YOURLIST);   

So, try to create a List of arrays with Questions and then serialize this list into JSON

letronje's solution only works for very simple pages. document.body.innerHTML += takes the HTML text of the body, appends the iframe HTML, and sets the innerHTML of the page to that string. This will wipe out any event bindings your page has, amongst other things. Create an element and use appendChild instead.

$.post('/create_binary_file.php', postData, function(retData) {
  var iframe = document.createElement("iframe");
  iframe.setAttribute("src", retData.url);
  iframe.setAttribute("style", "display: none");
  document.body.appendChild(iframe);
}); 

Or using jQuery

$.post('/create_binary_file.php', postData, function(retData) {
  $("body").append("<iframe src='" + retData.url+ "' style='display: none;' ></iframe>");
}); 

What this actually does: perform a post to /create_binary_file.php with the data in the variable postData; if that post completes successfully, add a new iframe to the body of the page. The assumption is that the response from /create_binary_file.php will include a value 'url', which is the URL that the generated PDF/XLS/etc file can be downloaded from. Adding an iframe to the page that references that URL will result in the browser promoting the user to download the file, assuming that the web server has the appropriate mime type configuration.

Even if you install the Oracle JDK, your $JAVA_HOME variable should refer to the path of the JRE that is inside the JDK root. You can refer to my other answer to a similar question for more details.

Instructions

• Copy the python file to /bin:

  sudo cp -i /path/to/your_script.py /bin

• Add A New Cron Job:

  sudo crontab -e

  Scroll to the bottom and add the following line (after all the #'s):

  @reboot python /bin/your_script.py &

  The “&” at the end of the line means the command is run in the background and it won’t stop the system booting up.

• Test it:

  sudo reboot

Practical example:

• Add this file to your Desktop: test_code.py (run it to check that it works for you)

  from os.path import expanduser
  import datetime
  
  file = open(expanduser("~") + '/Desktop/HERE.txt', 'w')
  file.write("It worked!\n" + str(datetime.datetime.now()))
  file.close()
  

• Run the following commands:

  sudo cp -i ~/Desktop/test_code.py /bin

  sudo crontab -e

• Add the following line and save it:

  @reboot python /bin/test_code.py &

• Now reboot your computer and you should find a new file on your Desktop: HERE.txt

use the PHP function:

getcwd()

Gets the current working directory.

Turns out it needs to be specified via escaped unicode. This question is related and contains the answer.

The solution:

h2:after {
    content: "\00a0";
}

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);
  }

see https://jsfiddle.net/8xwocrp6/7/

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

In later versions of CMake, one way to do it on each target is:

set_target_properties(MyTarget PROPERTIES COMPILE_FLAGS "-m32" LINK_FLAGS "-m32")

I don't know of a way to do it globally.

I think fontsize: command in YAML only works for LaTeX / pdf. Apart, in standard latex classes (article, book, and report) only three font sizes are accepted (10pt, 11pt, and 12pt).

Regarding appearance (different font types and colors), you can specify a theme:. See Appearance and Style.

I guess, what you are looking for is your own css. Make a file called style.css, save it in the same folder as your .Rmd and include it in the YAML header:

---
output:
  html_document:
    css: style.css
---

In the css-file you define your font-type and size:

/* Whole document: */
body{
  font-family: Helvetica;
  font-size: 16pt;
}
/* Headers */
h1,h2,h3,h4,h5,h6{
  font-size: 24pt;
}

I also had this issue and it arose because I re-made the project and then forgot to re-link it by reference in a dependent project.

Thus it was linking by reference to the old project instead of the new one.

It is important to know that there is a bug in re-adding a previously linked project by reference. You've got to manually delete the reference in the vcxproj and only then can you re-add it. This is a known issue in Visual studio according to msdn.

String guid = System.Guid.NewGuid().ToString();

Otherwise it's a delegate.

You can always use Robomongo. As of v0.8.3 there is a tool that can do this by right-clicking on the collection and selecting "Copy Collection to Database"

For details, see http://blog.robomongo.org/whats-new-in-robomongo-0-8-3/

This feature was removed in 0.8.5 due to its buggy nature so you will have to use 0.8.3 or 0.8.4 if you want to try it out.

Click the mse7.exe installed along with Office typically at \Program Files\Microsoft Office\OFFICE11.

This will open up the debugger, open the file and then run the debugger in the GUI mode.

Possibly browser returns String representation of some integer value? Actually int can't be null. May be you could check for null, if value is not null, then transform String representation to int.

The ExecuteNonQuery method is used for SQL statements that are not queries, such as INSERT, UPDATE, ... You want to use ExecuteScalar or ExecuteReader if you expect your statement to return results (i.e. a query).

I ended up using a normal hyperlink along with Url.Action, as in:

<a href='<%= Url.Action("Show", new { controller = "Browse", id = node.Id }) %>'
  data-nodeId='<%= node.Id %>'>
  <%: node.Name %>
</a>

It's uglier, but you've got a little more control over the a tag, which is sometimes useful in heavily AJAXified sites.

Every function inside a class, and every class variable must take the self argument as pointed.

class mystuff:
    def average(a,b,c): #get the average of three numbers
            result=a+b+c
            result=result/3
            return result
    def sum(self,a,b):
            return a+b


print mystuff.average(9,18,27) # should raise error
print mystuff.sum(18,27) # should be ok

If class variables are involved:

 class mystuff:
    def setVariables(self,a,b):
            self.x = a
            self.y = b
            return a+b
    def mult(self):
            return x * y  # This line will raise an error
    def sum(self):
            return self.x + self.y

 print mystuff.setVariables(9,18) # Setting mystuff.x and mystuff.y
 print mystuff.mult() # should raise error
 print mystuff.sum()  # should be ok

CABForum Baseline Requirements

I see no one has mentioned the section in the Baseline Requirements yet. I feel they are important.

Q: SSL - How do Common Names (CN) and Subject Alternative Names (SAN) work together?
A: Not at all. If there are SANs, then CN can be ignored. -- At least if the software that does the checking adheres very strictly to the CABForum's Baseline Requirements.

(So this means I can't answer the "Edit" to your question. Only the original question.)

CABForum Baseline Requirements, v. 1.2.5 (as of 2 April 2015), page 9-10:

9.2.2 Subject Distinguished Name Fields
a. Subject Common Name Field
Certificate Field: subject:commonName (OID 2.5.4.3)
Required/Optional: Deprecated (Discouraged, but not prohibited)
Contents: If present, this field MUST contain a single IP address or Fully-Qualified Domain Name that is one of the values contained in the Certificate’s subjectAltName extension (see Section 9.2.1).

EDIT: Links from @Bruno's comment

RFC 2818: HTTP Over TLS, 2000, Section 3.1: Server Identity:

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

RFC 6125: Representation and Verification of Domain-Based Application Service Identity within Internet Public Key Infrastructure Using X.509 (PKIX) Certificates in the Context of Transport Layer Security (TLS), 2011, Section 6.4.4: Checking of Common Names:

[...] if and only if the presented identifiers do not include a DNS-ID, SRV-ID, URI-ID, or any application-specific identifier types supported by the client, then the client MAY as a last resort check for a string whose form matches that of a fully qualified DNS domain name in a Common Name field of the subject field (i.e., a CN-ID).

You might want to specify language just to be safe, but

Making the custom rating bar with layer list and selectors is complex, it is better to override the RatingBar class and create a custom RatingBar. createBackgroundDrawableShape() is the function where you should put your empty state png and createProgressDrawableShape() is the function where you should put your filled state png.

Note: This code will not work with svg for now.

public class CustomRatingBar extends RatingBar {

    @Nullable
    private Bitmap mSampleTile;

    public ShapeDrawableRatingBar(final Context context, final AttributeSet attrs) {
        super(context, attrs);
        setProgressDrawable(createProgressDrawable());
    }

    @Override
    protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        if (mSampleTile != null) {
            final int width = mSampleTile.getWidth() * getNumStars();
            setMeasuredDimension(resolveSizeAndState(width, widthMeasureSpec, 0), getMeasuredHeight());
        }
    }

    protected LayerDrawable createProgressDrawable() {
        final Drawable backgroundDrawable = createBackgroundDrawableShape();
        LayerDrawable layerDrawable = new LayerDrawable(new Drawable[]{
            backgroundDrawable,
            backgroundDrawable,
            createProgressDrawableShape()
        });

        layerDrawable.setId(0, android.R.id.background);
        layerDrawable.setId(1, android.R.id.secondaryProgress);
        layerDrawable.setId(2, android.R.id.progress);
        return layerDrawable;
    }

    protected Drawable createBackgroundDrawableShape() {
        final Bitmap tileBitmap = drawableToBitmap(getResources().getDrawable(R.drawable.ic_star_empty));
        if (mSampleTile == null) {
            mSampleTile = tileBitmap;
        }
        final ShapeDrawable shapeDrawable = new ShapeDrawable(getDrawableShape());
        final BitmapShader bitmapShader = new BitmapShader(tileBitmap, Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        shapeDrawable.getPaint().setShader(bitmapShader);
        return shapeDrawable;
    }

    protected Drawable createProgressDrawableShape() {
        final Bitmap tileBitmap = drawableToBitmap(getResources().getDrawable(R.drawable.ic_star_full));

        final BitmapShader bitmapShader = new BitmapShader(tileBitmap, Shader.TileMode.REPEAT, Shader.TileMode.CLAMP);
        shapeDrawable.getPaint().setShader(bitmapShader);
        return new ClipDrawable(shapeDrawable, Gravity.LEFT, ClipDrawable.HORIZONTAL);
    }

    Shape getDrawableShape() {
        final float[] roundedCorners = new float[]{5, 5, 5, 5, 5, 5, 5, 5};
        return new RoundRectShape(roundedCorners, null, null);
    }

    public static Bitmap drawableToBitmap(Drawable drawable) {
        if (drawable instanceof BitmapDrawable) {
            return ((BitmapDrawable) drawable).getBitmap();
        }

        int width = drawable.getIntrinsicWidth();
        width = width > 0 ? width : 1;
        int height = drawable.getIntrinsicHeight();
        height = height > 0 ? height : 1;

        final Bitmap bitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
        final Canvas canvas = new Canvas(bitmap);
        drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());
        drawable.draw(canvas);

        return bitmap;
    }
}

For deleting the branch you have to stash the changes made on the branch or you need to commit the changes you made on the branch. Follow the below steps if you made any changes in the current branch.

1. git stash or git commit -m "XXX"
2. git checkout master
3. git branch -D merchantApi

Note: Above steps will delete the branch locally.

Try this for Xamarin.Android (Cross Platform)

edittext.EditorAction += (object sender, TextView.EditorActionEventArgs e) {
       if (e.ActionId.Equals (global::Android.Views.InputMethods.ImeAction.Done)) {
           //TODO Something
       }
};

print("{latitude} {longitude}".format(**geopoint))

I think that the idea of setting the Auto Return values as described above by Kevin is a bit strange!

Say, for example, that you have a number of websites that use the same PayPal account to handle your payments, or say that you have a number of sections in one website that perform different purchasing tasks, and require different return-addresses when the payment is completed. If I put a button on my page as described above in the 'Sample form using PHP for direct payments' section, you can see that there is a line there:

input type="hidden" name="return" value="https://www.yoursite.com/checkout_complete.php"

where you set the individual return value. Why does it have to be set generally, in the profile section as well?!?!

Also, because you can only set one value in the Profile Section, it means (AFAIK) that you cannot use the Auto Return on a site with multiple actions.

Comments please??

You can also extract the event code from the HTML, like this :

<input type="checkbox" id="check_all_1" name="check_all_1" title="Select All" />
<label for="check_all_1">Select All</label>

<script>
function selectAll(frmElement, chkElement) {
    // ...
}
document.getElementById("check_all_1").onclick = function() {
    selectAll(document.wizard_form, this);
}
</script>

Since PHP >= 5.2.2 you can use the DateTime class as such:

if (new DateTime() > new DateTime("2010-05-15 16:00:00")) {
    # current time is greater than 2010-05-15 16:00:00
    # in other words, 2010-05-15 16:00:00 has passed
}

The string passed to the DateTime constructor is parsed according to these rules.

Note that it is also possible to use time and strtotime functions. See original answer.

This should get you access to applicationContext from anywhere allowing you to get applicationContext anywhere that can use it; Toast, getString(), sharedPreferences, etc.

The Singleton:

package com.domain.packagename;

import android.content.Context;

/**
 * Created by Versa on 10.09.15.
 */
public class ApplicationContextSingleton {
    private static PrefsContextSingleton mInstance;
    private Context context;

    public static ApplicationContextSingleton getInstance() {
        if (mInstance == null) mInstance = getSync();
        return mInstance;
    }

    private static synchronized ApplicationContextSingleton getSync() {
        if (mInstance == null) mInstance = new PrefsContextSingleton();
        return mInstance;
    }

    public void initialize(Context context) {
        this.context = context;
    }

    public Context getApplicationContext() {
        return context;
    }

}

Initialize the Singleton in your Application subclass:

package com.domain.packagename;

import android.app.Application;

/**
 * Created by Versa on 25.08.15.
 */
public class mApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        ApplicationContextSingleton.getInstance().initialize(this);
    }
}

If I´m not wrong, this gives you a hook to applicationContext everywhere, call it with ApplicationContextSingleton.getInstance.getApplicationContext(); You shouldn´t need to clear this at any point, as when application closes, this goes with it anyway.

Remember to update AndroidManifest.xml to use this Application subclass:

<?xml version="1.0" encoding="utf-8"?>

<manifest
    xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.domain.packagename"
    >

<application
    android:allowBackup="true"
    android:name=".mApplication" <!-- This is the important line -->
    android:label="@string/app_name"
    android:theme="@style/AppTheme"
    android:icon="@drawable/app_icon"
    >

Please let me know if you see anything wrong here, thank you. :)

Put the source in a folder outside yourt workspace. Rightclick in the project-explorer, and select "Import..."

Import the project in your workspace as an Android project. Try to build it, and make sure it is marked as a library project. Also make sure it is build with Google API support, if not you will get compile errors.

Then, in right click on your main project in the project explorer. Select properties, then select Android on the left. In the library section below, click "Add"..

The mapview-balloons library should now be available to add to your project..

No, this will not work. The best you will be able to do is to iterate through all values and check them yourself:

boolean empty = true;
for (Object item : arrayList) {
    if (item != null) {
        empty = false;
        break;
    }
}
