atan(x) Returns the principal value of the arc tangent of x, expressed in radians.

atan2(y,x) Returns the principal value of the arc tangent of y/x, expressed in radians.

Notice that because of the sign ambiguity, a function cannot determine with certainty in which quadrant the angle falls only by its tangent value (atan alone). You can use atan2 if you need to determine the quadrant.

Note that -lm may not always need to be specified even if you use some C math functions.

For example, the following simple program:

#include <stdio.h>
#include <math.h>

int main() {

    printf("output: %f\n", sqrt(2.0));
    return 0;
}

can be compiled and run successfully with the following command:

gcc test.c -o test

Tested on gcc 7.5.0 (on Ubuntu 16.04) and gcc 4.8.0 (on CentOS 7).

The post here gives some explanations:

The math functions you call are implemented by compiler built-in functions

Too hard? Your TA is... well, the phrase would probably get me banned. Anyways, check to see if numb is negative. If it is then multiply numa by -1 and do numb = abs(numb). Then do the loop.

awk '$3 ~ /snow/ { print }' dummy_file 

If you are using Webdriver then the item you are looking for is Selected.

Often times in the render of the checkbox doesn't actually apply the attribute checked unless specified.

So what you would look for in Selenium Webdriver is this

isChecked = e.findElement(By.tagName("input")).Selected;

As there is no Selected in WebDriver Java API, the above code should be as follows:

isChecked = e.findElement(By.tagName("input")).isSelected();

You can use transitions to delay the :hover effect you want, if the effect is CSS-based.

For example

div{
    transition: 0s background-color;
}

div:hover{
    background-color:red;    
    transition-delay:1s;
}

this will delay applying the the hover effects (background-color in this case) for one second.

Demo of delay on both hover on and off:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
    transition-delay:1s;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;_x000D_
}

<div>delayed hover</div>

Demo of delay only on hover on:

div{_x000D_
    display:inline-block;_x000D_
    padding:5px;_x000D_
    margin:10px;_x000D_
    border:1px solid #ccc;_x000D_
    transition: 0s background-color;_x000D_
}_x000D_
div:hover{_x000D_
    background-color:red;    _x000D_
    transition-delay:1s;_x000D_
}

<div>delayed hover</div>

Vendor Specific Extentions for Transitions and W3C CSS3 transitions

I think you are wrapping your exception in another exception (which isn't in your code above). If you try out this code:

public static void main(String[] args) {
    try {
        throw new RuntimeException("Cannot move file");
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null, "Error: " + ex.getMessage());
    }
}

...you will see a popup that says exactly what you want.

However, to solve your problem (the wrapped exception) you need get to the "root" exception with the "correct" message. To do this you need to create a own recursive method getRootCause:

public static void main(String[] args) {
    try {
        throw new Exception(new RuntimeException("Cannot move file"));
    } catch (Exception ex) {
        JOptionPane.showMessageDialog(null,
                                      "Error: " + getRootCause(ex).getMessage());
    }
}

public static Throwable getRootCause(Throwable throwable) {
    if (throwable.getCause() != null)
        return getRootCause(throwable.getCause());

    return throwable;
}

Note: Unwrapping exceptions like this however, sort of breaks the abstractions. I encourage you to find out why the exception is wrapped and ask yourself if it makes sense.

DISTINCT is the keyword you're looking for.

In MSSQL, copying unique rows from a table to another can be done like this:

SELECT DISTINCT column_name
INTO newTable
FROM srcTable

The column_name is the column you're searching the unique values from.

Tested and works.

In your Gemfile, add the following:

gem 'example', :git => 'git://github.com/example.git'

You can also add ref, branch and tag options,

For example if you want to download from a particular branch:

gem 'example', :git => "git://github.com/example.git", :branch => "my-branch"

Then run:

bundle install

Use this code between two words:

& vbCrLf &

Using this, the next word displays on the next line.

You need to return a view which has a friendly error message to the user

catch (Exception ex)
{
   // to do :log error
   return View("Error");
}

You should not be showing the internal details of your exception(like exception stacktrace etc) to the user. You should be logging the relevant information to your error log so that you can go through it and fix the issue.

If your request is an ajax request, You may return a JSON response with a proper status flag which client can evaluate and do further actions

[HttpPost]
public ActionResult Create(CustomerVM model)
{
  try
  {
   //save customer
    return Json(new { status="success",message="customer created"});
  }
  catch(Exception ex)
  {
    //to do: log error
   return Json(new { status="error",message="error creating customer"});
  }
} 

If you want to show the error in the form user submitted, You may use ModelState.AddModelError method along with the Html helper methods like Html.ValidationSummary etc to show the error to the user in the form he submitted.

Very late to the party but hopefully this will help someone, was in the same situation for about a hour without any of the solutions mentioned above working. (On a Windows 10 machine).

In the Settings/Preferences dialog (Ctrl+Alt+S), from the side menu select Project: | Project Interpreter.

Check which packages you currently have installed (You need SQLAlchemy and Flask-SQLAlchemy). Double click on any package name, an 'Available Packages' menu will open.

Search for the missing package(s) and click install.

You can create a subclass of the view type, and override the onSizeChanged method.

I wanted to have scaling compound drawables on my text views that didn't require me to mess around with defining bitmap drawables in xml, etc. and did it this way:

public class StatIcon extends TextView {

    private Bitmap mIcon;

    public void setIcon(int drawableId) {
    mIcon = BitmapFactory.decodeResource(RIApplication.appResources,
            drawableId);
    }

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        if ((w > 0) && (mIcon != null))
            this.setCompoundDrawablesWithIntrinsicBounds(
                null,
                new BitmapDrawable(Bitmap.createScaledBitmap(mIcon, w, w,
                        true)), null, null);

        super.onSizeChanged(w, h, oldw, oldh);
    }

}

(Note that I used w twice, not h, as in this case I was putting the icon above the text, and thus the icon shouldn't have the same height as the text view)

This can be applied to background drawables, or anything else you want to resize relative to your view size. onSizeChanged() is called the first time the View is made, so you don't need any special cases for initialising the size.

I've being going round in circles with Firefox 43, El Capitan and WHM/cPanel SSL installation continually getting the Untrusted site error - I didn't buy the certificate it was handed over to me to install as the last guy walked out the door. Turns out I was installing under the wrong domain because I missed off the www - but the certificate still installed against the domain, when I installed the certificate in WHM using www.domain.com.au it installed now worries and the FF error has gone - the certificate works fine for both www and non-www.

This is difficult to achieve, but the cookie expiration date can be set in another cookie. This cookie can then be read later to get the expiration date. Maybe there is a better way, but this is one of the methods to solve your problem.

You have to use the encoding "Windows-1252".

header('Content-Encoding: Windows-1252');
header('Content-type: text/csv; charset=Windows-1252');
header("Content-Disposition: attachment; filename={$filename}");

Maybe you have to convert your strings:

private function convertToWindowsCharset($string) {
  $encoding = mb_detect_encoding($string);

  return iconv($encoding, "Windows-1252", $string);
}

CREATE PROCEDURE usp_GenerateDROP
    @Pattern AS varchar(255)
    ,@PrintQuery AS bit
    ,@ExecQuery AS bit
AS
BEGIN
    DECLARE @sql AS varchar(max)

    SELECT @sql = COALESCE(@sql, '') + 'DROP TABLE [' + TABLE_NAME + ']' + CHAR(13) + CHAR(10)
    FROM INFORMATION_SCHEMA.TABLES
    WHERE TABLE_NAME LIKE @Pattern

    IF @PrintQuery = 1 PRINT @sql
    IF @ExecQuery = 1 EXEC (@sql)
END

To summarize an attribute accessor aka attr_accessor gives you two free methods.

Like in Java they get called getters and setters.

Many answers have shown good examples so I'm just going to be brief.

#the_attribute

and

#the_attribute=

In the old ruby docs a hash tag # means a method. It could also include a class name prefix... MyClass#my_method

A more elegant solution could be:

def progressBar(current, total, barLength = 20):
    percent = float(current) * 100 / total
    arrow   = '-' * int(percent/100 * barLength - 1) + '>'
    spaces  = ' ' * (barLength - len(arrow))

    print('Progress: [%s%s] %d %%' % (arrow, spaces, percent), end='\r')

call this function with value and endvalue, result should be

Progress: [------------->      ] 69 %

Note: Python 2.x version here.

As stated here: Why use Fragment#setRetainInstance(boolean)?

you can also use fragments method setRetainInstance(true) like this:

public class MyFragment extends Fragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        // keep the fragment and all its data across screen rotation
        setRetainInstance(true);

    }
}

Length of an array:

UBound(columns)-LBound(columns)+1

UBound alone is not the best method for getting the length of every array as arrays in VBA can start at different indexes, e.g Dim arr(2 to 10)

UBound will return correct results only if the array is 1-based (starts indexing at 1 e.g. Dim arr(1 to 10). It will return wrong results in any other circumstance e.g. Dim arr(10)

More on the VBA Array in this VBA Array tutorial.

In some versions, it stores it under

<installed path>\system\oracle.jdeveloper.db.connection.11.1.1.0.11.42.44
\IDEConnections.xml

The server-side processing language in use (eg PHP, .net, etc) isn't specified, but if it's PHP, grab the required number (or all the records) and instead of randomising in the query use PHP's shuffle function. I don't know if .net has an equivalent function but if it does then use that if you're using .net

ORDER BY RAND() can have quite a performance penalty, depending on how many records are involved.

I think your code is right. If you run the following code it converts the string '60' which is treated as varchar and it returns integer 60, if there is integer containing string in second it works.

select CONVERT(bigint,'60') as seconds 

and it returns

60

If you are using Notepad++ editor Goto ctrl + F choose tab 3 find in files and enter:

1. Find What = text1*.*text2
2. Filters : .
3. Search mode = Regular Expression
4. Directory = enter the path of the directory you want to search in. You can check Follow current doc. to have the path of the current file to be filled.

Try the Select helper class and see if that makes any difference?

String valueToSelect= "Germany";
WebElement select = driver.findElement(By.id("selection"));
Select dropDown = new Select(select);           
String selected = dropDown.getFirstSelectedOption().getText();
if(selected.equals(valueToSelect)) {//do stuff already selected}
List<WebElement> Options = dropDown.getOptions();
for(WebElement option:Options){
  if(option.getText().equals(valueToSelect)){
       option.click();  
  }
}

As stated in comments below, you can use also the SET ROWCOUNT clause, but just for SQL Server 2014 and older.

SET ROWCOUNT 10

UPDATE messages
SET status = 10 
WHERE status = 0 

SET ROWCOUNT 0

More info: http://msdn.microsoft.com/en-us/library/ms188774.aspx

Or with a temp table

DECLARE @t TABLE (id INT)
INSERT @t (id)
SELECT TOP 10 id
FROM messages
WHERE status = 0
ORDER BY priority DESC

UPDATE messages
SET status = 10
WHERE id IN (SELECT id FROM @t)

The following code will disable cut, copy and paste from full page.

$(document).ready(function () {
   $('body').bind('cut copy paste', function (e) {
      e.preventDefault();
   });
});

The full tutorial and working demo can be found from here - Disable cut, copy and paste using jQuery

Adapted from this post on Processing JSON with jq, you can use the select(bool) like this:

$ jq '.[] | select(.location=="Stockholm")' json
{
  "location": "Stockholm",
  "name": "Walt"
}
{
  "location": "Stockholm",
  "name": "Donald"
}

Use:

overflow: hidden;
height: 100%;
position: fixed;
width: 100%;

Normally I would agree with Yaakov Ellis but in this special case there is another viable solution:

Use two tables:

Table: Item
Columns: ItemID, Title, Content
Indexes: ItemID

Table: Tag
Columns: ItemID, Title
Indexes: ItemId, Title

This has some major advantages:

First it makes development much simpler: in the three-table solution for insert and update of item you have to lookup the Tag table to see if there are already entries. Then you have to join them with new ones. This is no trivial task.

Then it makes queries simpler (and perhaps faster). There are three major database queries which you will do: Output all Tags for one Item, draw a Tag-Cloud and select all items for one Tag Title.

All Tags for one Item:

3-Table:

SELECT Tag.Title 
  FROM Tag 
  JOIN ItemTag ON Tag.TagID = ItemTag.TagID
 WHERE ItemTag.ItemID = :id

2-Table:

SELECT Tag.Title
FROM Tag
WHERE Tag.ItemID = :id

Tag-Cloud:

3-Table:

SELECT Tag.Title, count(*)
  FROM Tag
  JOIN ItemTag ON Tag.TagID = ItemTag.TagID
 GROUP BY Tag.Title

2-Table:

SELECT Tag.Title, count(*)
  FROM Tag
 GROUP BY Tag.Title

Items for one Tag:

3-Table:

SELECT Item.*
  FROM Item
  JOIN ItemTag ON Item.ItemID = ItemTag.ItemID
  JOIN Tag ON ItemTag.TagID = Tag.TagID
 WHERE Tag.Title = :title

2-Table:

SELECT Item.*
  FROM Item
  JOIN Tag ON Item.ItemID = Tag.ItemID
 WHERE Tag.Title = :title

But there are some drawbacks, too: It could take more space in the database (which could lead to more disk operations which is slower) and it's not normalized which could lead to inconsistencies.

The size argument is not that strong because the very nature of tags is that they are normally pretty small so the size increase is not a large one. One could argue that the query for the tag title is much faster in a small table which contains each tag only once and this certainly is true. But taking in regard the savings for not having to join and the fact that you can build a good index on them could easily compensate for this. This of course depends heavily on the size of the database you are using.

The inconsistency argument is a little moot too. Tags are free text fields and there is no expected operation like 'rename all tags "foo" to "bar"'.

So tldr: I would go for the two-table solution. (In fact I'm going to. I found this article to see if there are valid arguments against it.)

Try

select * from dataset
where id = 2
order by date limit 1

Been a while since I did sql, so this might need some tweaking.

Are you using TortoiseSVN and just upgraded? I've had that problem before when moving from 1.4 to 1.5 and not rebooting. (Try a reboot).

The reason you need to reboot is because the cache file gets all funky.

Otherwise, to just move on, export that working copy into a new folder (don't copy the .svn hidden folders), re-checkout the project, and move all your code back, then proceed with your commit.

For 2.7, try the following:

fh = logging.handlers.RotatingFileHandler(LOGFILE, maxBytes=(1048576*5), backupCount=7)

This is how I add css using jQuery ajax. Hope it helps someone..

$.ajax({
            url:"site/test/style.css",
            success:function(data){
                 $("<style></style>").appendTo("head").html(data);
            }
        })

I believe the standard MIME type for Excel files is application/vnd.ms-excel.

Regarding the name of the document, you should set the following header in the response:

header('Content-Disposition: attachment; filename="name_of_excel_file.xls"');

I set up a simple 3-column range on Sheet1 with Country, City, and Language in columns A, B, and C. The following code autofilters the range and then pastes only one of the columns of autofiltered data to another sheet. You should be able to modify this for your purposes:

Sub CopyPartOfFilteredRange()
    Dim src As Worksheet
    Dim tgt As Worksheet
    Dim filterRange As Range
    Dim copyRange As Range
    Dim lastRow As Long

    Set src = ThisWorkbook.Sheets("Sheet1")
    Set tgt = ThisWorkbook.Sheets("Sheet2")

    ' turn off any autofilters that are already set
    src.AutoFilterMode = False

    ' find the last row with data in column A
    lastRow = src.Range("A" & src.Rows.Count).End(xlUp).Row

    ' the range that we are auto-filtering (all columns)
    Set filterRange = src.Range("A1:C" & lastRow)

    ' the range we want to copy (only columns we want to copy)
    ' in this case we are copying country from column A
    ' we set the range to start in row 2 to prevent copying the header
    Set copyRange = src.Range("A2:A" & lastRow)

    ' filter range based on column B
    filterRange.AutoFilter field:=2, Criteria1:="Rio de Janeiro"

    ' copy the visible cells to our target range
    ' note that you can easily find the last populated row on this sheet
    ' if you don't want to over-write your previous results
    copyRange.SpecialCells(xlCellTypeVisible).Copy tgt.Range("A1")

End Sub

Note that by using the syntax above to copy and paste, nothing is selected or activated (which you should always avoid in Excel VBA) and the clipboard is not used. As a result, Application.CutCopyMode = False is not necessary.

As per my knowledge, finish function close the current displayed screen only.

Refer this example (where see the answer given by 'plusminus'), it will sure help you to close your application.

To find any sub-string from large string:

string_value:=('This is String,Please search string 'Ple');

Then to find the string 'Ple' from String_value we can do as:

select substr(string_value,instr(string_value,'Ple'),length('Ple')) from dual;

You will find result: Ple

The block approach avoids running the lookup algorithm for every key:

[dict enumerateKeysAndObjectsUsingBlock:^(id key, id value, BOOL* stop) {
  NSLog(@"%@ => %@", key, value);
}];

Even though NSDictionary is implemented as a hashtable (which means that the cost of looking up an element is O(1)), lookups still slow down your iteration by a constant factor.

My measurements show that for a dictionary d of numbers ...

NSMutableDictionary* dict = [NSMutableDictionary dictionary];
for (int i = 0; i < 5000000; ++i) {
  NSNumber* value = @(i);
  dict[value.stringValue] = value;
}

... summing up the numbers with the block approach ...

__block int sum = 0;
[dict enumerateKeysAndObjectsUsingBlock:^(NSString* key, NSNumber* value, BOOL* stop) {
  sum += value.intValue;
}];

... rather than the loop approach ...

int sum = 0;
for (NSString* key in dict)
  sum += [dict[key] intValue];

... is about 40% faster.

EDIT: The new SDK (6.1+) appears to optimise loop iteration, so the loop approach is now about 20% faster than the block approach, at least for the simple case above.

If you had use strict turned on, you would have found out that $++foo doesn't make any sense.

Here's how to do it:

use strict;
use warnings;

my $file = 'SnPmaster.txt';
open my $info, $file or die "Could not open $file: $!";

while( my $line = <$info>)  {   
    print $line;    
    last if $. == 2;
}

close $info;

This takes advantage of the special variable $. which keeps track of the line number in the current file. (See perlvar)

If you want to use a counter instead, use

my $count = 0;
while( my $line = <$info>)  {   
    print $line;    
    last if ++$count == 2;
}

right click on your project and run as maven install then again run your application. if this didnt work go to the folder of your project directly start command line and run 'mvn install'

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

The right syntax is like:

SELECT * FROM table1 INNER JOIN table2 ON table1.primaryKey = table2.ForeignKey
INNER JOIN table3 ON table3.primaryKey = table2.ForeignKey

Orthe last line joining table3 on table1 like:

ON table3.ForeignKey= table1.PrimaryKey

This code creates the file temp.xls in the desktop but it uses the SpecialFolders property, which is very useful sometimes!

set WshShell = WScript.CreateObject("WScript.Shell")
strDesktop = WshShell.SpecialFolders("Desktop")

set objExcel = CreateObject("Excel.Application")
Set objWorkbook = objExcel.Workbooks.Add()
objWorkbook.SaveAs(strDesktop & "\temp.xls")

To follow up on Theo's suggestion with my findings (apologies - I don't currently have enough reputation to post this as a comment)

First, this is how to use several named parameters:

String commandString = "INSERT INTO Users (Name, Desk, UpdateTime) VALUES (:Name, :Desk, :UpdateTime)";
using (OracleCommand command = new OracleCommand(commandString, _connection, _transaction))
{
    command.Parameters.Add("Name", OracleType.VarChar, 50).Value = strategy;
    command.Parameters.Add("Desk", OracleType.VarChar, 50).Value = deskName ?? OracleString.Null;
    command.Parameters.Add("UpdateTime", OracleType.DateTime).Value = updated;
    command.ExecuteNonQuery();
}

However, I saw no variation in speed between:

• constructing a new commandString for each row (String.Format)
• constructing a now parameterized commandString for each row
• using a single commandString and changing the parameters

I'm using System.Data.OracleClient, deleting and inserting 2500 rows inside a transaction

I realize this is an old question but I found this on mozilla.org and think it applies.

A button can be of three types: submit, reset, or button. A click on a submit button sends the form's data to the web page defined by the action attribute of the element.

A click on a reset button resets all the form widgets to their default value immediately. From a UX point of view, this is considered bad practice.

A click on a button button does... nothing! That sounds silly, but it's amazingly useful to build custom buttons with JavaScript.

https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Forms/My_first_HTML_form#And_a_<button>_to_finish

In my case, setting Copy to Output Directory to Copy Always and Build did not do the trick, while Rebuild did.

Hope this helps someone!

You're asking how to add a dimension to a NumPy array, so that that dimension can then be grown to accommodate new data. A dimension can be added as follows:

image = image[..., np.newaxis]

This comes up in Java 5 and later if you're using collections without type specifiers (e.g., Arraylist() instead of ArrayList<String>()). It means that the compiler can't check that you're using the collection in a type-safe way, using generics.

To get rid of the warning, just be specific about what type of objects you're storing in the collection. So, instead of

List myList = new ArrayList();

use

List<String> myList = new ArrayList<String>();

In Java 7 you can shorten generic instantiation by using Type Inference.

List<String> myList = new ArrayList<>();

Do not hardcode path like //data/data/<Your-Application-Package-Name>/databases/<your-database-name>. Well it does work in most cases, but this one is not working in devices where device can support multiple users. The path can be like //data/user/10/<Your-Application-Package-Name>/databases/<your-database-name>. Possible solution to this is using context.getDatabasePath(<your-database-name>).

Firefox 64 adds support for the spec draft CSS Scrollbars Module Level 1, which adds two new properties of scrollbar-width and scrollbar-color which give some control over how scrollbars are displayed.

You can set scrollbar-color to one of the following values (descriptions from MDN):

• auto Default platform rendering for the track portion of the scrollbar, in the absence of any other related scrollbar color properties.
• dark Show a dark scrollbar, which can be either a dark variant of scrollbar provided by the platform, or a custom scrollbar with dark colors.
• light Show a light scrollbar, which can be either a light variant of scrollbar provided by the platform, or a custom scrollbar with light colors.
• <color> <color> Applies the first color to the scrollbar thumb, the second to the scrollbar track.

Note that dark and light values are not currently implemented in Firefox.

macOS notes:

The auto-hiding semi-transparent scrollbars that are the macOS default cannot be colored with this rule (they still choose their own contrasting color based on the background). Only the permanently showing scrollbars (System Preferences > Show Scroll Bars > Always) are colored.

You can set scrollbar-width to one of the following values (descriptions from MDN):

• auto The default scrollbar width for the platform.
• thin A thin scrollbar width variant on platforms that provide that option, or a thinner scrollbar than the default platform scrollbar width.
• none No scrollbar shown, however the element will still be scrollable.

You can also set a specific length value, according to the spec. Both thin and a specific length may not do anything on all platforms, and what exactly it does is platform-specific. In particular, Firefox doesn't appear to be currently support a specific length value (this comment on their bug tracker seems to confirm this). The thin keywork does appear to be well-supported however, with macOS and Windows support at-least.

It's probably worth noting that the length value option and the entire scrollbar-width property are being considered for removal in a future draft, and if that happens this particular property may be removed from Firefox in a future version.

Try this solution if the Reset Password option (of SQL Developer) did not work:

Step 1: Open Run SQL Command Line (from the start menu, which comes with SQL Developer installation package)

Step 2: Run the following commands:

Note: If password has already expired, Changing password for <user> option will automatically come.

I had this issue occurring with mailto: and tel: links inside an iframe (in Chrome, not a webview). Clicking the links would show the grey "page not found" page and inspecting the page showed it had a ERR_UNKNOWN_URL_SCHEME error.

Adding target="_blank", as suggested by this discussion of the issue fixed the problem for me.

SIMPLE SOLUTION

I wanted to support apps pre api 23 and instead of using checkSelfPermission I used a try / catch

try {
   location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
} catch (SecurityException e) {
   dialogGPS(this.getContext()); // lets the user know there is a problem with the gps
}

In Debug mode Android Studio connects to your Device via socket(:8600). Somehow your socket connection is choked and thus not responding to incoming connections.

Restart Android Studio and your problem will be resolved

It is the difference between greedy and non-greedy quantifiers.

Consider the input 101000000000100.

Using 1.*1, * is greedy - it will match all the way to the end, and then backtrack until it can match 1, leaving you with 1010000000001.
.*? is non-greedy. * will match nothing, but then will try to match extra characters until it matches 1, eventually matching 101.

All quantifiers have a non-greedy mode: .*?, .+?, .{2,6}?, and even .??.

In your case, a similar pattern could be <([^>]*)> - matching anything but a greater-than sign (strictly speaking, it matches zero or more characters other than > in-between < and >).

See Quantifier Cheat Sheet.

You may try this:-

Scanner scan = new Scanner(System.in);
System.out.println("Type a sentence and press enter.");
String input = scan.nextLine();
String strippedInput = input.replaceAll("\\W", "");
System.out.println("Your string: " + strippedInput);

[^\w] matches a non-word character, so the above regular expression will match and remove all non-word characters.

Although, some users already answered this question already, I am giving an example of application settings to solve this problem.

I had the same issue. I am using https://github.com/grevory/angular-local-storage module in my angularjs application. If you configure your app as follows, it will save variable in session storage instead of local storage. Therefore, if you close the browser or close the tab, session storage will be removed automatically. You do not need to do anything.

app.config(function (localStorageServiceProvider) {
  localStorageServiceProvider
  .setPrefix('myApp')
  .setStorageType('sessionStorage')
});

Hope it will help.

There is a pseudocolumn called %%physloc%% that shows the physical address of the row.

There are a couple fixes:

Use display: block;

<img style="display:block;" width="100%" height="100%" src="http://dummyimage.com/68x68/000/fff" />

or use vertical-align: bottom;

Standing on the shoulders of charles-clayton and @vikas-gautam, I added the string test which is needed if a column has strings as in OP.

return isNaN(a-b) ? (a === b) ? 0 : (a < b) ? -1 : 1 : a-b  ;

The test isNaN(a-b) determines if the strings cannot be coerced to numbers. If they can then the a-b test is valid.

Note that sorting a column of mixed types will always give an entertaining result as the strict equality test (a === b) will always return false. See MDN here

This is the full script with Logger test - using Google Apps Script.

function testSort(){

function sortByCol(arr, colIndex){
    arr.sort(sortFunction);
    function sortFunction(a, b) {
        a = a[colIndex];
        b = b[colIndex];
       return isNaN(a-b) ? (a === b) ? 0 : (a < b) ? -1 : 1 : a-b  ;  // test if text string - ie cannot be coerced to numbers.
       // Note that sorting a column of mixed types will always give an entertaining result as the strict equality test will always return false
       // see https://developer.mozilla.org/en-US/docs/Web/JavaScript/Equality_comparisons_and_sameness

You use separator when you are building a file path. So in unix the separator is /. So if you wanted to build the unix path /var/temp you would do it like this:

String path = File.separator + "var"+ File.separator + "temp"

You use the pathSeparator when you are dealing with a list of files like in a classpath. For example, if your app took a list of jars as argument the standard way to format that list on unix is: /path/to/jar1.jar:/path/to/jar2.jar:/path/to/jar3.jar

So given a list of files you would do something like this:

String listOfFiles = ...
String[] filePaths = listOfFiles.split(File.pathSeparator);

Could be simplified to this:

SELECT article FROM table1 ORDER BY publish_date DESC FETCH FIRST 20 ROWS ONLY;

You could also add many argument in the ORDER BY that is just comma separated like: ORDER BY publish_date, tab2, tab3 DESC etc...

Everything in S3 is an object. To you, it may be files and folders. But to S3, they're just objects.

Objects that end with the delimiter (/ in most cases) are usually perceived as a folder, but it's not always the case. It depends on the application. Again, in your case, you're interpretting it as a folder. S3 is not. It's just another object.

In your case above, the object users/<user-id>/contacts/<contact-id>/ exists in S3 as a distinct object, but the object users/<user-id>/ does not. That's the difference in your responses. Why they're like that, we cannot tell you, but someone made the object in one case, and didn't in the other. You don't see it in the AWS Management Console because the console is interpreting it as a folder and hiding it from you.

Since S3 just sees these things as objects, it won't "exclude" certain things for you. It's up to the client to deal with the objects as they should be dealt with.

Your Solution

Since you're the one that doesn't want the folder objects, you can exclude it yourself by checking the last character for a /. If it is, then ignore the object from the response.

Unfortunately, you're out of luck here.

There is inherit to copy a certain value from a parent to its children, but there is no property the other way round (which would involve another selector to decide which style to revert).

You will have to revert style changes manually:

div { color: green; }

form div { color: red; }

form div div.content { color: green; }

If you have access to the markup, you can add several classes to style precisely what you need:

form div.sub { color: red; }

form div div.content { /* remains green */ }

Edit: The CSS Working Group is up to something:

div.content {
  all: revert;
}

No idea, when or if ever this will be implemented by browsers.

Edit 2: As of March 2015 all modern browsers but Safari and IE/Edge have implemented it: https://twitter.com/LeaVerou/status/577390241763467264 (thanks, @Lea Verou!)

Edit 3: default was renamed to revert.

import re
pattern = re.compile("<(\d{4,5})>")

for i, line in enumerate(open('test.txt')):
    for match in re.finditer(pattern, line):
        print 'Found on line %s: %s' % (i+1, match.group())

A couple of notes about the regex:

• You don't need the ? at the end and the outer (...) if you don't want to match the number with the angle brackets, but only want the number itself
• It matches either 4 or 5 digits between the angle brackets

Update: It's important to understand that the match and capture in a regex can be quite different. The regex in my snippet above matches the pattern with angle brackets, but I ask to capture only the internal number, without the angle brackets.

More about regex in python can be found here : Regular Expression HOWTO

Building on the excellent answers by rafx and Sina, here is a snippet that only targets Firefox and replaces the default button with a down-caret copied from Bootstrap's icon theme.

Before:

After:

@-moz-document url-prefix() {
  select.form-control {
    padding-right: 25px;
    background-image: url("data:image/svg+xml,\
      <svg version='1.1' xmlns='http://www.w3.org/2000/svg' width='14px'\
           height='14px' viewBox='0 0 1200 1000' fill='rgb(51,51,51)'>\
        <path d='M1100 411l-198 -199l-353 353l-353 -353l-197 199l551 551z'/>\
      </svg>");
    background-repeat: no-repeat;
    background-position: calc(100% - 7px) 50%;
    -moz-appearance: none;
    appearance: none;
  }
}

Here is the JSFiddle

Here's a way to do it without formulas or macros:

1. Save your CSV as Excel
2. Select any cells that might have commas
3. Open to the Format menu and click on Cells
4. Pick the Custom format
5. Enter this => \"@\"
6. Click OK
7. Save the file as CSV

Use env.

For example, env FOO=BAR command. Note that the environment variables will be restored/unchanged again when command finishes executing.

Just be careful about about shell substitution happening, i.e. if you want to reference $FOO explicitly on the same command line, you may need to escape it so that your shell interpreter doesn't perform the substitution before it runs env.

$ export FOO=BAR
$ env FOO=FUBAR bash -c 'echo $FOO'
FUBAR
$ echo $FOO
BAR

The order() function fails when the column has levels or factor. It works properly when stringsAsFactors=FALSE is used in data.frame creation.

use get_loaded_extensions() PHP function

other way is:

sudo service apache2 reload

Why don't you use spring's TransactionTemplate to programmatically control transactions? You could also restructure your code so that each "transaction block" has it's own @Transactional method, but given that it's a test I would opt for programmatic control of your transactions.

Also note that the @Transactional annotation on your runnable won't work (unless you are using aspectj) as the runnables aren't managed by spring!

@RunWith(SpringJUnit4ClassRunner.class)
//other spring-test annotations; as your database context is dirty due to the committed transaction you might want to consider using @DirtiesContext
public class TransactionTemplateTest {

@Autowired
PlatformTransactionManager platformTransactionManager;

TransactionTemplate transactionTemplate;

@Before
public void setUp() throws Exception {
    transactionTemplate = new TransactionTemplate(platformTransactionManager);
}

@Test //note that there is no @Transactional configured for the method
public void test() throws InterruptedException {

    final Contract c1 = transactionTemplate.execute(new TransactionCallback<Contract>() {
        @Override
        public Contract doInTransaction(TransactionStatus status) {
            Contract c = contractDOD.getNewTransientContract(15);
            contractRepository.save(c);
            return c;
        }
    });

    ExecutorService executorService = Executors.newFixedThreadPool(5);

    for (int i = 0; i < 5; ++i) {
        executorService.execute(new Runnable() {
            @Override  //note that there is no @Transactional configured for the method
            public void run() {
                transactionTemplate.execute(new TransactionCallback<Object>() {
                    @Override
                    public Object doInTransaction(TransactionStatus status) {
                        // do whatever you want to do with c1
                        return null;
                    }
                });
            }
        });
    }

    executorService.shutdown();
    executorService.awaitTermination(10, TimeUnit.SECONDS);

    transactionTemplate.execute(new TransactionCallback<Object>() {
        @Override
        public Object doInTransaction(TransactionStatus status) {
            // validate test results in transaction
            return null;
        }
    });
}

}

You are looking for Java generics

List<MyClass> list = new ArrayList<MyClass>();

Here's a tutorial http://docs.oracle.com/javase/tutorial/java/generics/index.html

you should divide hours by 24 not 11
like this:
select to_char(sysdate - 2/24, 'dd-mon-yyyy HH24') from dual

EDIT:

After your comments this actually makes perfect sense why you don't get a histogram of each different value. There are 1.4 million rows, and ten discrete buckets. So apparently each bucket is exactly 10% (to within what you can see in the plot).

A quick rerun of your data:

In [25]: df.hist(column='Trip_distance')

Prints out absolutely fine.

The df.hist function comes with an optional keyword argument bins=10 which buckets the data into discrete bins. With only 10 discrete bins and a more or less homogeneous distribution of hundreds of thousands of rows, you might not be able to see the difference in the ten different bins in your low resolution plot:

In [34]: df.hist(column='Trip_distance', bins=50)

Remember that in Python when you do:

    list1 = ['apples','bananas','pineapples']
    list2 = list1

List2 isn't storing the actual list, but a reference to list1. So when you do anything to list1, list2 changes as well. use the copy module (not default, download on pip) to make an original copy of the list(copy.copy() for simple lists, copy.deepcopy() for nested ones). This makes a copy that doesn't change with the first list.

Guava provides this: Lists.reverse(List)

List<String> letters = ImmutableList.of("a", "b", "c");
List<String> reverseView = Lists.reverse(letters); 
System.out.println(reverseView); // [c, b, a]

Unlike Collections.reverse, this is purely a view... it doesn't alter the ordering of elements in the original list. Additionally, with an original list that is modifiable, changes to both the original list and the view are reflected in the other.

The best "Pythonic" way to do this, exploiting the with statement, is listed as Example #6 in PEP 343, which gives the background of the statement.

@contextmanager
def opened_w_error(filename, mode="r"):
    try:
        f = open(filename, mode)
    except IOError, err:
        yield None, err
    else:
        try:
            yield f, None
        finally:
            f.close()

Used as follows:

with opened_w_error("/etc/passwd", "a") as (f, err):
    if err:
        print "IOError:", err
    else:
        f.write("guido::0:0::/:/bin/sh\n")

Yes you can if you are using HTML5, this code is valid not otherwise:

<a href="#foo"><div>.......</div></a>

If you are not using HTML5, you can make your link block:

<a href="#foo" id="link">Click Here</a>

CSS:

#link {
  display : block;
  width:100px;
  height:40px;
}

Notice that you can apply width, height only after making your link block level element.

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

I was inspired by @AniMenon to write a pythonic more general solution.

mylist = ['x', 3, 'b']
print('[{}]'.format(', '.join(map('{}'.format, mylist))))

It only uses the format method. No trace of str, and it allows for the fine tuning of the elements format. For example, if you have float numbers as elements of the list, you can adjust their format, by adding a conversion specifier, in this case :.2f

mylist = [1.8493849, -6.329323, 4000.21222111]
print("[{}]".format(', '.join(map('{:.2f}'.format, mylist))))

The output is quite decent:

[1.85, -6.33, 4000.21]

jQuery.preferCulture("en-IN");
var price = jQuery.format(39.00, "c");

output is: Rs. 39.00

use jquery.glob.js,
    jQuery.glob.all.js

If you are using ES6 you can:

var sample = [1, 2, 3]

var result = sample.filter(elem => elem !== 2)

/* output */
[1, 3]

Also take notice filter does not update the existing array it will return a new filtered array every time.

Some of my pet peeves with Maven:

• The XML definition is super clumsy and verbose. Have they never heard of attributes?

• In its default configuration, it always scours the 'net on every operation. Regardless of whether this is useful for anything, it looks extremely silly to need Internet access for "clean".

• Again in the default, if I'm not careful to specify exact version numbers, it will pull the very latest updates off the 'net, regardless of whether these newest versions introduce dependency errors. In other words, you're placed at the mercy of other peoples' dependency management.

• The solution to all this network access is to turn it off by adding the -o option. But you have to remember to turn it off if you really want to do dependency updating!

• Another solution is to install your own "source control" server for dependencies. Surprise: Most projects already have source control, only that works with no additional setup!

• Maven builds are incredibly slow. Fiddling with network updates alleviates this, but Maven builds are still slow. And horribly verbose.

• The Maven plugin (M2Eclipse) integrates most poorly with Eclipse. Eclipse integrates reasonably smoothly with version control software and with Ant. Maven integration is very clunky and ugly by comparison. Did I mention slow?

• Maven continues to be buggy. Error messages are unhelpful. Too many developers are suffering from this.

Then this file server will make your life that little bit easier.

To install the simple static stuff server, use npm:

npm install -g static-server

Then to serve a file or a directory, simply run

$ serve path/to/stuff
Serving path/to/stuff on port 8001

That could even list folder content.

Unfortunately, it couldn't serve files :)

The sql array type is not neccessary. Not if the element type is a primitive one. (Varchar, number, date,...)

Very basic sample:

declare
  type TPidmList is table of sgbstdn.sgbstdn_pidm%type;
  pidms TPidmList;
begin
  select distinct sgbstdn_pidm
  bulk collect into pidms
  from sgbstdn
  where sgbstdn_majr_code_1 = 'HS04'
  and sgbstdn_program_1 = 'HSCOMPH';

  -- do something with pidms

  open :someCursor for
    select value(t) pidm
    from table(pidms) t;
end;

When you want to reuse it, then it might be interesting to know how that would look like. If you issue several commands than those could be grouped in a package. The private package variable trick from above has its downsides. When you add variables to a package, you give it state and now it doesn't act as a stateless bunch of functions but as some weird sort of singleton object instance instead.

e.g. When you recompile the body, it will raise exceptions in sessions that already used it before. (because the variable values got invalided)

However, you could declare the type in a package (or globally in sql), and use it as a paramter in methods that should use it.

create package Abc as
  type TPidmList is table of sgbstdn.sgbstdn_pidm%type;

  function CreateList(majorCode in Varchar, 
                      program in Varchar) return TPidmList;

  function Test1(list in TPidmList) return PLS_Integer;
  -- "in" to make it immutable so that PL/SQL can pass a pointer instead of a copy
  procedure Test2(list in TPidmList);
end;

create package body Abc as

  function CreateList(majorCode in Varchar, 
                      program in Varchar) return TPidmList is
    result TPidmList;
  begin
    select distinct sgbstdn_pidm
    bulk collect into result
    from sgbstdn
    where sgbstdn_majr_code_1 = majorCode
    and sgbstdn_program_1 = program;

    return result;
  end;

  function Test1(list in TPidmList) return PLS_Integer is
    result PLS_Integer := 0;
  begin
    if list is null or list.Count = 0 then
      return result;
    end if;

    for i in list.First .. list.Last loop
      if ... then
        result := result + list(i);
      end if;
    end loop;
  end;

  procedure Test2(list in TPidmList) as
  begin
    ...
  end;

  return result;
end;

How to call it:

declare
  pidms constant Abc.TPidmList := Abc.CreateList('HS04', 'HSCOMPH');
  xyz PLS_Integer;
begin
  Abc.Test2(pidms);
  xyz := Abc.Test1(pidms);
  ...

  open :someCursor for
    select value(t) as Pidm,
           xyz as SomeValue
    from   table(pidms) t;
end;

@Sotirios Delimanolis answer do the job however I was looking for comparing strings within this mockMvc assertion

So here it is

.andExpect(content().string("\"Username already taken - please try with different username\""));

Of course my assertion fail:

java.lang.AssertionError: Response content expected:
<"Username already taken - please try with different username"> but was:<"Something gone wrong">

because:

  MockHttpServletResponse:
            Body = "Something gone wrong"

So this is proof that it works!

Use EntityScanner if you can bear external dependency.It will inject your all entity classes seamlessly even from multiple packages. Just add following line after configuration setup.

Configuration configuration = new Configuration().configure();    
EntityScanner.scanPackages("com.fz.epms.db.model.entity").addTo(configuration);
// And following depencency if you are using Maven
<dependency>
        <groupId>com.github.v-ladynev</groupId>
        <artifactId>fluent-hibernate-core</artifactId>
        <version>0.3.1</version>
</dependency>

This way you don't need to declare all entities in hibernate mapping file.

Use

cursor: pointer;
cursor: hand;

if you want to have a crossbrowser result!

Below is a Util class in my project:

        public static void SerializeToFormatter<F>(object obj, string path) where F : IFormatter, new()
        {

            {
                throw new NullReferenceException("obj Cannot be Null.");
            }

            if (obj.GetType().IsSerializable == false)
            {
                //  throw new 
            }
            IFormatter f = new F();
            SerializeToFormatter(obj, path, f);
        }

        public static T DeserializeFromFormatter<T, F>(string path) where F : IFormatter, new()

        {
            XmlSerializer xs = new XmlSerializer(typeof(T));
            using (FileStream fs = File.Create(path))
            {
                xs.Serialize(fs, obj);
            }
        }

            {
                return (T)xs.Deserialize(fs);
            }
        }

        public static T DeserializeFromXml<T>(string xml)
        {
            T result;

            var ser = new XmlSerializer(typeof(T));
            using (var tr = new StringReader(xml))
            {
                result = (T)ser.Deserialize(tr);
            }
            return result;
        }


        private static void SerializeToFormatter(object obj, string path, IFormatter formatter)
        {
            using (FileStream fs = File.Create(path))
            {
                formatter.Serialize(fs, obj);
            }
        }

}

Try:

div{_x000D_
-webkit-box-shadow:0px 1px 1px #de1dde;_x000D_
 -moz-box-shadow:0px 1px 1px #de1dde;_x000D_
 box-shadow:0px 1px 1px #de1dde;_x000D_
  }

<div>wefwefwef</div>

It generally adds a 1px blurred shadow 1px from the bottom of the box

box-shadow: [horizontal offset] [vertical offset] [blur radius] [color];

PHP_EOL is a predefined constant in PHP since PHP 4.3.10 and PHP 5.0.2. See the manual posting:

Using this will save you extra coding on cross platform developments.

IE.

$data = 'some data'.PHP_EOL;
$fp = fopen('somefile', 'a');
fwrite($fp, $data);

If you looped through this twice you would see in 'somefile':

some data
some data

For me adding AppRoutingModule to my imports solved the problem.

    imports: [
     BrowserModule,
     AppRoutingModule,
     RouterModule.forRoot([
      {
        path: 'new-cmp',
        component: NewCmpComponent
      }
     ])
    ]

Python lacks the tail recursion optimizations common in functional languages like lisp. In Python, recursion is limited to 999 calls (see sys.getrecursionlimit).

If 999 depth is more than you are expecting, check if the implementation lacks a condition that stops recursion, or if this test may be wrong for some cases.

I dare to say that in Python, pure recursive algorithm implementations are not correct/safe. A fib() implementation limited to 999 is not really correct. It is always possible to convert recursive into iterative, and doing so is trivial.

It is not reached often because in many recursive algorithms the depth tend to be logarithmic. If it is not the case with your algorithm and you expect recursion deeper than 999 calls you have two options:

1) You can change the recursion limit with sys.setrecursionlimit(n) until the maximum allowed for your platform:

sys.setrecursionlimit(limit):

Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python.

The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash.

2) You can try to convert the algorithm from recursive to iterative. If recursion depth is bigger than allowed by your platform, it is the only way to fix the problem. There are step by step instructions on the Internet and it should be a straightforward operation for someone with some CS education. If you are having trouble with that, post a new question so we can help.

The second is almost correct:

{
    "foos" : [{
        "prop1":"value1",
        "prop2":"value2"
    }, {
        "prop1":"value3", 
        "prop2":"value4"
    }]
}

DLL Export Viewer by NirSoft can be used to display exported functions in a DLL.

This utility displays the list of all exported functions and their virtual memory addresses for the specified DLL files. You can easily copy the memory address of the desired function, paste it into your debugger, and set a breakpoint for this memory address. When this function is called, the debugger will stop in the beginning of this function.

You need to make sure that the value you pass to the directory argument is an absolute path, corrected for the current location of your application.

The best way to do this is to configure UPLOAD_FOLDER as a relative path (no leading slash), then make it absolute by prepending current_app.root_path:

@app.route('/uploads/<path:filename>', methods=['GET', 'POST'])
def download(filename):
    uploads = os.path.join(current_app.root_path, app.config['UPLOAD_FOLDER'])
    return send_from_directory(directory=uploads, filename=filename)

It is important to reiterate that UPLOAD_FOLDER must be relative for this to work, e.g. not start with a /.

A relative path could work but relies too much on the current working directory being set to the place where your Flask code lives. This may not always be the case.

IntelliJ IDEA 2018.3.6

Using macOS Mojave Version 10.14.4 and pressing ?F12(Alt+F12) will open Sound preferences.

A solution without changing the current keymap is to use the command above with the key fn.

fn ? F12(fn+Alt+F12) will open the Terminal. And you can use ShiftEsc to close it.

A general solution requires parsing the URL into a RFC 2396 compliant URI (note that this is an old version of the URI standard, which java.net.URI uses).

I have written a Java URL parsing library that makes this possible: galimatias. With this library, you can achieve your desired behaviour with this code:

String urlString = //...
URLParsingSettings settings = URLParsingSettings.create()
  .withStandard(URLParsingSettings.Standard.RFC_2396);
URL url = URL.parse(settings, urlString);

Note that galimatias is in a very early stage and some features are experimental, but it is already quite solid for this use case.

I see a lot of "Do it this way" but I don't see any answers to "Why?"

So: Why should you @class in your header and #import only in your implementation? You're doubling your work by having to @class and #import all the time. Unless you make use of inheritance. In which case you'll be #importing multiple times for a single @class. Then you have to remember to remove from multiple different files if you suddenly decide you don't need access to a declaration anymore.

Importing the same file multiple times isn't an issue because of the nature of #import. Compiling performance isn't really an issue either. If it were, we wouldn't be #importing Cocoa/Cocoa.h or the like in pretty much every header file we have.

Here is generalized solution using numpy and comparision for correctness with tensorflow ans scipy:

Data preparation:

import numpy as np

np.random.seed(2019)

batch_size = 1
n_items = 3
n_classes = 2
logits_np = np.random.rand(batch_size,n_items,n_classes).astype(np.float32)
print('logits_np.shape', logits_np.shape)
print('logits_np:')
print(logits_np)

Output:

logits_np.shape (1, 3, 2)
logits_np:
[[[0.9034822  0.3930805 ]
  [0.62397    0.6378774 ]
  [0.88049906 0.299172  ]]]

Softmax using tensorflow:

import tensorflow as tf

logits_tf = tf.convert_to_tensor(logits_np, np.float32)
scores_tf = tf.nn.softmax(logits_np, axis=-1)

print('logits_tf.shape', logits_tf.shape)
print('scores_tf.shape', scores_tf.shape)

with tf.Session() as sess:
    scores_np = sess.run(scores_tf)

I made this in my code to do that

note: I am a beginner.

It is my jsp code.

<%
java.sql.Connection Conn = DBconnector.SetDBConnection(); /* make connector as you make in your code */
Statement st = null;
ResultSet rs = null;
st = Conn.createStatement();
rs = st.executeQuery("select * from department"); %>
<tr> 
    <td> 
        Student Major  : <select name ="Major">
        <%while(rs.next()){ %>
        <option value="<%=rs.getString(1)%>"><%=rs.getString(1)%></option>

                         </select> 
   </td> 

Another reason to use $state.params is for non-URL based state, which (to my mind) is woefully underdocumented and very powerful.

I just discovered this while googling about how to pass state without having to expose it in the URL and answered a question elsewhere on SO.

Basically, it allows this sort of syntax:

<a ui-sref="toState(thingy)" class="list-group-item" ng-repeat="thingy in thingies">{{ thingy.referer }}</a>

Recently I faced this issue with SQL 2008 R2 and the below solution worked for me:

1) Create a new database with the same name as the one you are trying to restore 2) While restoring, use the same name you used above and in the options, click the overwrite option

You might give the above a shot if the other solutions don't work.

Check the following one-liner:

print('\n'.join("%s\n%s" % (key1,('\n'.join("%s : %r" % (key2,val2) for (key2,val2) in val1.items()))) for (key1,val1) in cars.items()))

Output:

A
speed : 70
color : 2
B
speed : 60
color : 3

Starting with matplotlib 1.4.0 there is now an an interactive backend for use in the notebook

%matplotlib notebook

There are a few version of IPython which do not have that alias registered, the fall back is:

%matplotlib nbagg

If that does not work update you IPython.

To play with this, goto tmpnb.org

and paste

%matplotlib notebook

import pandas as pd
import numpy as np
import matplotlib

from matplotlib import pyplot as plt
import seaborn as sns

ts = pd.Series(np.random.randn(1000), index=pd.date_range('1/1/2000', periods=1000))
ts = ts.cumsum()

df = pd.DataFrame(np.random.randn(1000, 4), index=ts.index,
                  columns=['A', 'B', 'C', 'D'])
df = df.cumsum()
df.plot(); plt.legend(loc='best')    

into a code cell (or just modify the existing python demo notebook)

You can absolutely inject mocks on MyLauncher in your test. I am sure if you show what mocking framework you are using someone would be quick to provide an answer. With mockito I would look into using @RunWith(MockitoJUnitRunner.class) and using annotations for myLauncher. It would look something like what is below.

@RunWith(MockitoJUnitRunner.class)
public class MyLauncherTest
    @InjectMocks
    private MyLauncher myLauncher = new MyLauncher();

    @Mock
    private MyService myService;

    @Test
    public void someTest() {

    }
}

It doesn't recognize that you have a master branch, but I found a way to get around it. I found out that there's nothing special about a master branch, you can just create another branch and call it master branch and that's what I did.

To create a master branch:

git checkout -b master

And you can work off of that.

I don't know about Windows (never used it), but on a Linux system you just have to create a build directory (in the top source directory)

mkdir build-dir

go inside it

cd build-dir

then run cmake and point to the parent directory

cmake ..

and finally run make

make

Notice that make and cmake are different programs. cmake is a Makefile generator, and the make utility is governed by a Makefile textual file. See cmake & make wikipedia pages.

NB: On Windows, cmake might operate so could need to be used differently. You'll need to read the documentation (like I did for Linux)

mysqli is provided by php-mysql-5.3.3-40.el6_6.x86_64

You may need to try the following

yum install php-mysql-5.3.3-40.el6_6.x86_64

You can use the following to set the text from the code:

toggleButton.setText(textOff);
// Sets the text for when the button is first created.

toggleButton.setTextOff(textOff);
// Sets the text for when the button is not in the checked state.

toggleButton.setTextOn(textOn);
// Sets the text for when the button is in the checked state.

To set the text using xml, use the following:

android:textOff="The text for the button when it is not checked."
android:textOn="The text for the button when it is checked." 

This information is from here

use android-28 with build-tools at version 28.0.3; or build-tools at version 26.0.3.

or try this: yes | sudo sdkmanager --licenses

Using sshpass works best. To just include your password in scp use the ' ':

scp user1:'password'@xxx.xxx.x.5:sys_config /var/www/dev/

On providing this as input ,

li = ['server=mpilgrim', 'uid=sa', 'database=master', 'pwd=secret']
s = ";".join(li)
print(s)

Python returns this as output :

'server=mpilgrim;uid=sa;database=master;pwd=secret'

Try this code

$('window').scrollDown(function(){$(#div).hide()});

$('window').scrollUp(function(){ $(#div).show() });

You need module.exports:

Exports

An object which is shared between all instances of the current module and made accessible through require(). exports is the same as the module.exports object. See src/node.js for more information. exports isn't actually a global but rather local to each module.

For example, if you would like to expose variableName with value "variableValue" on sourceFile.js then you can either set the entire exports as such:

module.exports = { variableName: "variableValue" };

Or you can set the individual value with:

module.exports.variableName = "variableValue";

To consume that value in another file, you need to require(...) it first (with relative pathing):

const sourceFile = require('./sourceFile');
console.log(sourceFile.variableName);

Alternatively, you can deconstruct it.

const { variableName } = require('./sourceFile');
//            current directory --^
// ../     would be one directory down
// ../../  is two directories down

If all you want out of the file is variableName then

./sourceFile.js:

const variableName = 'variableValue'
module.exports = variableName

./consumer.js:

const variableName = require('./sourceFile')

Edit (2020):

Since Node.js version 8.9.0, you can also use ECMAScript Modules with varying levels of support. The documentation.

• For Node v13.9.0 and beyond, experimental modules are enabled by default
• For versions of Node less than version 13.9.0, use --experimental-modules

Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js when the nearest parent package.json file contains a top-level field "type" with a value of "module".
• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Once you have it setup, you can use import and export.

Using the example above, there are two approaches you can take

./sourceFile.js:

// This is a named export of variableName
export const variableName = 'variableValue'
// Alternatively, you could have exported it as a default. 
// For sake of explanation, I'm wrapping the variable in an object
// but it is not necessary. 
// You can actually omit declaring what variableName is here. 
// { variableName } is equivalent to { variableName: variableName } in this case. 
export default { variableName: variableName } 

./consumer.js:

// There are three ways of importing. 
// If you need access to a non-default export, then 
// you use { nameOfExportedVariable } 
import { variableName } from './sourceFile'
console.log(variableName) // 'variableValue'

// Otherwise, you simply provide a local variable name 
// for what was exported as default.
import sourceFile from './sourceFile'
console.log(sourceFile.variableName) // 'variableValue'

./sourceFileWithoutDefault.js:

// The third way of importing is for situations where there
// isn't a default export but you want to warehouse everything
// under a single variable. Say you have:
export const a = 'A'
export const b = 'B'

./consumer2.js

// Then you can import all exports under a single variable
// with the usage of * as:
import * as sourceFileWithoutDefault from './sourceFileWithoutDefault'

console.log(sourceFileWithoutDefault.a) // 'A'
console.log(sourceFileWithoutDefault.b) // 'B'

// You can use this approach even if there is a default export:
import * as sourceFile from './sourceFile'

// Default exports are under the variable default:
console.log(sourceFile.default) // { variableName: 'variableValue' }

// As well as named exports:
console.log(sourceFile.variableName) // 'variableValue

How to hard reset Visual Studio instance

When developing extensions sometimes you just mess up, others someone else does. If you start getting errors loading even the most mundane extensions, these are the instructions to hard reset your instance.

Close Visual Studio (if you haven’t already).
Open the registry editor (regedit.exe)
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}
Delete the HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\{version}_Config
Delete the %LOCALAPPDATA%\Microsoft\VisualStudio\{version} directory.

Enjoy your brand new Visual Studio instance.

• Use {version}=10.0 for Visual Studio 2010
• Use {version}=11.0 for Visual Studio 2012
• Use {version}=12.0 for Visual Studio 2013

If on the other side you want to reset the experimental hive you can do the same to with the ‘{version}Exp’ ones.

Happy coding!

If any background task runs more than 10 minutes,then the task will be suspended and code block specified with beginBackgroundTaskWithExpirationHandler is called to clean up the task. background remaining time can be checked with [[UIApplication sharedApplication] backgroundTimeRemaining]. Initially when the App is in foreground backgroundTimeRemaining is set to bigger value. When the app goes to background, you can see backgroundTimeRemaining value decreases from 599.XXX ( 1o minutes). once the backgroundTimeRemaining becomes ZERO, the background task will be suspended.

        //1)Creating iOS Background Task
        __block UIBackgroundTaskIdentifier background_task;
        background_task = [application beginBackgroundTaskWithExpirationHandler:^ {

               //This code block is execute when the application’s 
               //remaining background time reaches ZERO.
          }];


        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
            //### background task starts

            //#### background task ends
        });

        //2)Making background task Asynchronous
        if([[UIDevice currentDevice] respondsToSelector:@selector(isMultitaskingSupported)])

                background_task = UIBackgroundTaskInvalid;
            }];

                //### background task starts
                NSLog(@"Running in the background\n");
                while(TRUE)
                {

                [application endBackgroundTask: background_task];
                background_task = UIBackgroundTaskInvalid; 
            });
        }

@Cebjyre. The IDE whether Enterprise Manager or Management Studio is better than anything I have seen so far for MySQL. I say 'easier to use' because I can do many things in MSSQL where MySQL has no counterparts. In MySQL I have no idea how to tune the queries by simply looking at the query plan or looking at the statistics. The index tuning wizard in MSSQL takes most of the guess work on what indexes are missing or misplaced.

One shortcoming of MySQL is there's no max size for a database. The database would just increase in size till it fills up the disk. Imagine if this disk is sharing databases with other users and suddenly all of their queries are failing because their databases can't grow. I have reported this issue to MySQL long time ago. I don't think it's fixed yet.

seems you need to link with the obj file that implements tolayer5()

Update: your function declaration doesn't match the implementation:

      void tolayer5(int AorB, struct msg msgReceived)
      void tolayer5(int, char data[])

So compiler would treat them as two different functions (you are using c++). and it cannot find the implementation for the one you called in main().

For application-wide settings and for global constants I recommend to use Settingslogic. This settings are stored in YML file and can be accessed from models, views and controllers. Furthermore, you can create different settings for all your environments:

  # app/config/application.yml
  defaults: &defaults
    cool:
      sweet: nested settings
    neat_setting: 24
    awesome_setting: <%= "Did you know 5 + 5 = #{5 + 5}?" %>

    colors: "white blue black red green"

  development:
    <<: *defaults
    neat_setting: 800

  test:
    <<: *defaults

  production:
    <<: *defaults

Somewhere in the view (I prefer helper methods for such kind of stuff) or in a model you can get, for ex., array of colors Settings.colors.split(/\s/). It's very flexible. And you don't need to invent a bike.

This will remove the last comma and any whitespace after it:

str = str.replace(/,\s*$/, "");

It uses a regular expression:

• The / mark the beginning and end of the regular expression

• The , matches the comma

• The \s means whitespace characters (space, tab, etc) and the * means 0 or more

• The $ at the end signifies the end of the string

Here's what I had to do to setup basic auth on Ubuntu 14.04 (didn't find a guide anywhere else)

Basic squid conf

/etc/squid3/squid.conf instead of the super bloated default config file

auth_param basic program /usr/lib/squid3/basic_ncsa_auth /etc/squid3/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

# Choose the port you want. Below we set it to default 3128.
http_port 3128

Please note the basic_ncsa_auth program instead of the old ncsa_auth

squid 2.x

For squid 2.x you need to edit /etc/squid/squid.conf file and place:

auth_param basic program /usr/lib/squid/digest_pw_auth /etc/squid/passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Setting up a user

sudo htpasswd -c /etc/squid3/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid3 restart

squid 2.x

sudo htpasswd -c /etc/squid/passwords username_you_like

and enter a password twice for the chosen username then

sudo service squid restart

htdigest vs htpasswd

For the many people that asked me: the 2 tools produce different file formats:

• htdigest stores the password in plain text.
• htpasswd stores the password hashed (various hashing algos are available)

Despite this difference in format basic_ncsa_auth will still be able to parse a password file generated with htdigest. Hence you can alternatively use:

sudo htdigest -c /etc/squid3/passwords realm_you_like username_you_like

Beware that this approach is empirical, undocumented and may not be supported by future versions of Squid.

On Ubuntu 14.04 htdigest and htpasswd are both available in the [apache2-utils][1] package.

MacOS

Similar as above applies, but file paths are different.

Install squid

brew install squid

Start squid service

brew services start squid

Squid config file is stored at /usr/local/etc/squid.conf.

Comment or remove following line:

http_access allow localnet

Then similar to linux config (but with updated paths) add this:

auth_param basic program /usr/local/Cellar/squid/4.8/libexec/basic_ncsa_auth /usr/local/etc/squid_passwords
auth_param basic realm proxy
acl authenticated proxy_auth REQUIRED
http_access allow authenticated

Note that path to basic_ncsa_auth may be different since it depends on installed version when using brew, you can verify this with ls /usr/local/Cellar/squid/. Also note that you should add the above just bellow the following section:

#
# INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS
#

Now generate yourself a user:password basic auth credential (note: htpasswd and htdigest are also both available on MacOS)

htpasswd -c /usr/local/etc/squid_passwords username_you_like

Restart the squid service

brew services restart squid

Try:

printf "%X\n" ${MY_NUMBER}

# *** the shortest and best way ***
# getmtime --> sort by modified time
# getctime --> sort by created time

import glob,os

lst_files = glob.glob("*.txt")
lst_files.sort(key=os.path.getmtime)
print("\n".join(lst_files))

An alternative

N=3
STRING="one two three four"

arr=($STRING)
echo ${arr[N-1]}

The error tells you EXACTLY what the problem is (and running in the debugger or reading the stack trace will tell you exactly where the problem is):

C# Collection was modified; enumeration operation may not execute.

Your problem is the loop

foreach (KeyValuePair<int, int> kvp in rankings) {
    //
}

wherein you modify the collection rankings. In particular, the offensive line is

rankings[kvp.Key] = rankings[kvp.Key] + 4;

Before you enter the loop, add the following line:

var listOfRankingsToModify = new List<int>();

Replace the offending line with

listOfRankingsToModify.Add(kvp.Key);

and after you exit the loop

foreach(var key in listOfRankingsToModify) {
    rankings[key] = rankings[key] + 4;
}

That is, record what changes you need to make, and make them without iterating over the collection that you need to modify.

package javaapplication45;

public class JavaApplication45 extends Thread {

    public static void main(String[] args) {
        //even numbers
        Thread t1 = new Thread() {
            public void run() {
                for (int i = 1; i <= 20; i++) {
                    if (i % 2 == 0) {
                        System.out.println("even thread " + i);
                    }
                }
            }
        };
        t1.start();
        //odd numbers
        Thread t2 = new Thread() {
            public void run() {
                for (int i = 1; i <= 20; i++) {
                    if (i % 2 != 0) {
                        System.out.println("odd thread " + i);
                    }
                }
            }
        };
        t2.start();

    }

}

Sometimes implicit wait fails, saying that an element exists but it really doesn't.

The solution is to avoid using driver.findElement and to replace it with a custom method that uses an Explicit Wait implicitly. For example:

import org.openqa.selenium.NoSuchElementException;


public WebElement element(By locator){
    Integer timeoutLimitSeconds = 20;
    WebDriverWait wait = new WebDriverWait(driver, timeoutLimitSeconds);
    try {
        wait.until(ExpectedConditions.presenceOfElementLocated(locator));
    }
    catch(TimeoutException e){
        throw new NoSuchElementException(locator.toString());
    }
    WebElement element = driver.findElement(locator);
    return element;
}

There are additional reasons to avoid implicit wait other than sporadic, occasional failures (see this link).

You can use this "element" method in the same way as driver.findElement. For Example:

    driver.get("http://yoursite.html");
    element(By.cssSelector("h1.logo")).click();

If you really want to just wait a few seconds for troubleshooting or some other rare occasion, you can create a pause method similar to what selenium IDE offers:

    public void pause(Integer milliseconds){
    try {
        TimeUnit.MILLISECONDS.sleep(milliseconds);
    } catch (InterruptedException e) {
        e.printStackTrace();
    }
}

In SQL without SELECT you cannot result anything. Instead of IF-ELSE block I prefer to use CASE statement for this

SELECT CASE
         WHEN EXISTS (SELECT 1
                      FROM   tblGLUserAccess
                      WHERE  GLUserName = 'xxxxxxxx') THEN 1
         ELSE 2
       END 

get is a function that is called when you try to read the value player.health, like in:

console.log(player.health);

It's effectively not much different than:

player.getHealth = function(){
  return 10 + this.level*15;
}
console.log(player.getHealth());

The opposite of get is set, which would be used when you assign to the value. Since there is no setter, it seems that assigning to the player's health is not intended:

player.health = 5; // Doesn't do anything, since there is no set function defined

A very simple example:

var player = {_x000D_
  level: 5_x000D_
};_x000D_
_x000D_
Object.defineProperty(player, "health", {_x000D_
  get: function() {_x000D_
    return 10 + (player.level * 15);_x000D_
  }_x000D_
});_x000D_
_x000D_
console.log(player.health); // 85_x000D_
player.level++;_x000D_
console.log(player.health); // 100_x000D_
_x000D_
player.health = 5; // Does nothing_x000D_
console.log(player.health); // 100

So Why not use powershell to create the list of source files for you. Take a look at this script

param (
    [Parameter(Mandatory=$True)]
    [string]$root 
)

if (-not (Test-Path  -Path $root)) {    
throw "Error directory does not exist"
}

#get the full path of the root
$rootDir = get-item -Path $root
$fp=$rootDir.FullName;


$files = Get-ChildItem -Path $root -Recurse -File | 
         Where-Object { ".cpp",".cxx",".cc",".h" -contains $_.Extension} | 
         Foreach {$_.FullName.replace("${fp}\","").replace("\","/")}

$CMakeExpr = "set(SOURCES "

foreach($file in $files){

    $CMakeExpr+= """$file"" " ;
}
$CMakeExpr+=")"
return $CMakeExpr;

Suppose you have a folder with this structure

C:\Workspace\A
--a.cpp
C:\Workspace\B 
--b.cpp

Now save this file as "generateSourceList.ps1" for example, and run the script as

~>./generateSourceList.ps1 -root "C:\Workspace" > out.txt

out.txt file will contain

set(SOURCE "A/a.cpp" "B/b.cpp")

In PowerShell V2, @ is also the Splat operator.

PS> # First use it to create a hashtable of parameters:
PS> $params = @{path = "c:\temp"; Recurse= $true}
PS> # Then use it to SPLAT the parameters - which is to say to expand a hash table 
PS> # into a set of command line parameters.
PS> dir @params
PS> # That was the equivalent of:
PS> dir -Path c:\temp -Recurse:$true

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

As I understand, you want the average value for each id at each pass. The solution is

SELECT id, pass, avg(value) FROM data_r1
GROUP BY id, pass;

Using implode(), you can turn the array into a string.

$str = implode(',', $array); // 33160,33280,33180,...

Thanks to this post, I use this style to remove the red border that appears automatically with bootstrap when a required field is displayed, but user didn't have a chance to input anything already:

input.ng-pristine.ng-invalid {
    -webkit-box-shadow: none;
    -ms-box-shadow: none;
    box-shadow:none;
}

its not specific to bash windows 10. but if you want remove the bell terminal for zsh, just use the right option in zshrc. (for vim, answer already posted)

unsetopt beep

i have find this option quickly, but would find it even faster if its was on this post ^^

Issue: "PUSH Failed refs/head/ - pre-receive hook declined"

I've faced the problem of unable to push my changes to my origin branch and anything to master branch of a particular project repository as the size of that repo was over hard limit of 2GB. It was throwing the error. That's because we had pushed the test data unknowingly to bitbucket from other testing branches.

PUSH Failed refs/head/ - pre-receive hook declined

So tried checking is that the same with other project repo's and they weren't having any issues.

Fix:

My colleague noticed that when we cloned the project back locally, the size of the project was 110MB. So then we started cleaning the branches we merged earlier and active branches which are no more required. Once that cleaning is done for couple of branches we realized the size of the repo went drastically down from 2GB to 120MB. Then we tried to push the changes to my branch and it worked.

Running Latest Code Igniter 3.10

$this->load->helper('uri'); // or you can autoload it in config

print base_url($this->uri->uri_string());

I came across this problem just now and ended up resolving it like so: I opened up the offending .java file in Notepad++ and from the Encoding menu I selected "Convert to UTF-8 without BOM". Saved. Re-ran maven, all went through ok.

If the offending resource was not encoded in UTF-8 - as you have configured for your maven compiler plugin - you would see in the Encoding menu of Np++ a bullet mark next to the file's current encoding (in my case I saw it was set to "Encode in ANSI").

So your maven compiler plugin invoked the Java compiler with the -encoding option set to UTF-8, but the compiler encountered a ANSI-encoded source file and reported this as an error. This used to be a warning previously in Java 5 but is treated as an error in Java 6+

I tried the above methods, and no one can show the alert view, only when I put the presentViewController: method in a dispatch_async sentence:

dispatch_async(dispatch_get_main_queue(), ^ { [self presentViewController:alert animated:YES completion:nil]; });

Refer to Alternative to UIAlertView for iOS 9?.

One approach for Angular4 would be defining a constant at module level:

const api_endpoint = 'http://127.0.0.1:6666/api/';

@NgModule({
  declarations: [AppComponent],
  bootstrap: [AppComponent],
  providers: [
    MessageService,
    {provide: 'API_ENDPOINT', useValue: api_endpoint}
  ]
})
export class AppModule {
}

Then, in your service:

import {Injectable, Inject} from '@angular/core';

@Injectable()
export class MessageService {

    constructor(private http: Http, 
      @Inject('API_ENDPOINT') private api_endpoint: string) { }

    getMessages(): Observable<Message[]> {
        return this.http.get(this.api_endpoint+'/messages')
            .map(response => response.json())
            .map((messages: Object[]) => {
                return messages.map(message => this.parseData(message));
            });
    }

    private parseData(data): Message {
        return new Message(data);
    }
}

public static void main(String arg[])
{
    HashMap<String, ArrayList<String>> hashmap = 
        new HashMap<String, ArrayList<String>>();
    ArrayList<String> arraylist = new ArrayList<String>();
    arraylist.add("Hello");
    arraylist.add("World.");
    hashmap.put("my key", arraylist);
    arraylist = hashmap.get("not inserted");
    System.out.println(arraylist);
    arraylist = hashmap.get("my key");
    System.out.println(arraylist);
}

null
[Hello, World.]

Works fine... maybe you find your mistake in my code.

You are not returning. Change to

this.state.data.map(function(item, i){
  console.log('test');
  return <li>Test</li>;
})

Try this, it works fine for me:

1 . Modify your MainActivity section in AndroidManifest.xml, delete from it, line with MAIN category in intent-filter section

<activity android:name="ru.quickmessage.pa.MainActivity"
    android:configChanges="keyboardHidden|orientation"
    android:screenOrientation="portrait"
    android:label="@string/app_name"
    android:theme="@style/CustomTheme"
    android:launchMode="singleTask">
    <intent-filter>
        ==> <action android:name="android.intent.action.MAIN" /> <== Delete this line
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

2 . Create <activity-alias>, for each of your icons. Like this

<activity-alias android:label="@string/app_name" 
    android:icon="@drawable/icon" 
    android:name=".MainActivity-Red"
    android:enabled="false"
    android:targetActivity=".MainActivity">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>   
</activity-alias>

3 . Set programmatically: set ENABLE attribute for the appropriate activity-alias

 getPackageManager().setComponentEnabledSetting(
        new ComponentName("ru.quickmessage.pa", "ru.quickmessage.pa.MainActivity-Red"), 
            PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP);

Note, At least one must be enabled at all times.

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

Here are a few possibilities that don't parse the output of ls and that are 100% safe regarding files with spaces and funny symbols in their name. All of them will populate an array randf with a list of random files. This array is easily printed with printf '%s\n' "${randf[@]}" if needed.

• This one will possibly output the same file several times, and N needs to be known in advance. Here I chose N=42.

  a=( * )
  randf=( "${a[RANDOM%${#a[@]}]"{1..42}"}" )
  

  This feature is not very well documented.

• If N is not known in advance, but you really liked the previous possibility, you can use eval. But it's evil, and you must really make sure that N doesn't come directly from user input without being thoroughly checked!

  N=42
  a=( * )
  eval randf=( \"\${a[RANDOM%\${#a[@]}]\"\{1..$N\}\"}\" )
  

  I personally dislike eval and hence this answer!

• The same using a more straightforward method (a loop):

  N=42
  a=( * )
  randf=()
  for((i=0;i<N;++i)); do
      randf+=( "${a[RANDOM%${#a[@]}]}" )
  done
  

• If you don't want to possibly have several times the same file:

  N=42
  a=( * )
  randf=()
  for((i=0;i<N && ${#a[@]};++i)); do
      ((j=RANDOM%${#a[@]}))
      randf+=( "${a[j]}" )
      a=( "${a[@]:0:j}" "${a[@]:j+1}" )
  done
  

Note. This is a late answer to an old post, but the accepted answer links to an external page that shows terrible bash practice, and the other answer is not much better as it also parses the output of ls. A comment to the accepted answer points to an excellent answer by Lhunath which obviously shows good practice, but doesn't exactly answer the OP.

If after ./configure Makefile.in and Makefile.am are generated and make fail (by showing this following make: *** No targets specified and no makefile found. Stop.) so there is something not configured well, to solve it, first run "autoconf" commande to solve wrong configuration then re-run "./configure" commande and finally "make"

One think you should change is the call $state.go(). As described here:

• $state.go(to [, toParams] [, options])

The param passed should be the state name

$scope.create = function() {
  // instead of this
  //$state.go("/tab/newpost"); 

  // we should use this
  $state.go("tab.newpost"); 
};

Some cite from doc (the first parameter to of the [$state.go(to \[, toParams\] \[, options\]):

to

String Absolute State Name or Relative State Path

The name of the state that will be transitioned to or a relative state path. If the path starts with ^ or . then it is relative, otherwise it is absolute.

Some examples:

$state.go('contact.detail') will go to the 'contact.detail' state
$state.go('^') will go to a parent state.
$state.go('^.sibling') will go to a sibling state.
$state.go('.child.grandchild') will go to a grandchild state.

When the button is clicked, get the value of the input and use it to create an image element which is appended to the body (or anywhere else) :

<html>
<body>
<form>
    <input type="text" id="imagename" value="" />
    <input type="button" id="btn" value="GO" />
</form>
    <script type="text/javascript">
        document.getElementById('btn').onclick = function() {
            var val = document.getElementById('imagename').value,
                src = 'http://webpage.com/images/' + val +'.png',
                img = document.createElement('img');

            img.src = src;
            document.body.appendChild(img);
        }
    </script>
</body>
</html>

FIDDLE

the same in jQuery:

$('#btn').on('click', function() {
    var img = $('<img />', {src : 'http://webpage.com/images/' + $('#imagename').val() +'.png'});
    img.appendTo('body');
});

Allthough it's now a native type, it's still defined behind the scenes as an integer (int I think) where the literal false is 0 and true is 1. But I think all logic still consider anything but 0 as true, so strictly speaking the true literal is probably a keyword for the compiler to test if something is not false.

if(someval == true){

probably translates to:

if(someval !== false){ // e.g. someval !== 0

by the compiler

Adam Pierce's answer provides an hand-spun tokenizer taking in a const char*. It's a bit more problematic to do with iterators because incrementing a string's end iterator is undefined. That said, given string str{ "The quick brown fox" } we can certainly accomplish this:

auto start = find(cbegin(str), cend(str), ' ');
vector<string> tokens{ string(cbegin(str), start) };

while (start != cend(str)) {
    const auto finish = find(++start, cend(str), ' ');

    tokens.push_back(string(start, finish));
    start = finish;
}

Live Example

If you're looking to abstract complexity by using standard functionality, as On Freund suggests strtok is a simple option:

vector<string> tokens;

for (auto i = strtok(data(str), " "); i != nullptr; i = strtok(nullptr, " ")) tokens.push_back(i);

If you don't have access to C++17 you'll need to substitute data(str) as in this example: http://ideone.com/8kAGoa

Though not demonstrated in the example, strtok need not use the same delimiter for each token. Along with this advantage though, there are several drawbacks:

1. strtok cannot be used on multiple strings at the same time: Either a nullptr must be passed to continue tokenizing the current string or a new char* to tokenize must be passed (there are some non-standard implementations which do support this however, such as: strtok_s)
2. For the same reason strtok cannot be used on multiple threads simultaneously (this may however be implementation defined, for example: Visual Studio's implementation is thread safe)
3. Calling strtok modifies the string it is operating on, so it cannot be used on const strings, const char*s, or literal strings, to tokenize any of these with strtok or to operate on a string who's contents need to be preserved, str would have to be copied, then the copy could be operated on

c++20 provides us with split_view to tokenize strings, in a non-destructive manner: https://topanswers.xyz/cplusplus?q=749#a874

The previous methods cannot generate a tokenized vector in-place, meaning without abstracting them into a helper function they cannot initialize const vector<string> tokens. That functionality and the ability to accept any white-space delimiter can be harnessed using an istream_iterator. For example given: const string str{ "The quick \tbrown \nfox" } we can do this:

istringstream is{ str };
const vector<string> tokens{ istream_iterator<string>(is), istream_iterator<string>() };

Live Example

The required construction of an istringstream for this option has far greater cost than the previous 2 options, however this cost is typically hidden in the expense of string allocation.

If none of the above options are flexable enough for your tokenization needs, the most flexible option is using a regex_token_iterator of course with this flexibility comes greater expense, but again this is likely hidden in the string allocation cost. Say for example we want to tokenize based on non-escaped commas, also eating white-space, given the following input: const string str{ "The ,qu\\,ick ,\tbrown, fox" } we can do this:

const regex re{ "\\s*((?:[^\\\\,]|\\\\.)*?)\\s*(?:,|$)" };
const vector<string> tokens{ sregex_token_iterator(cbegin(str), cend(str), re, 1), sregex_token_iterator() };

Live Example

This is an old question, but since JavaScript is a moving target - it is possible in ES6 on implementation that support proper tail calls. On implementations with support for proper tail calls, you can have an unbounded number of active tail calls (i.e. tail calls doesn't "grow the stack").

A goto can be thought of as a tail call with no parameters.

The example:

start: alert("RINSE");
       alert("LATHER");
       goto start

can be written as

 function start() { alert("RINSE");
                    alert("LATHER");
                    return start() }

Here the call to start is in tail position, so there will be no stack overflows.

Here is a more complex example:

 label1:   A
           B
           if C goto label3
           D
 label3:   E
           goto label1

First, we split the source up into blocks. Each label indicates the start of a new block.

 Block1
     label1:   A
               B
               if C goto label3
               D

  Block2    
     label3:   E
               goto label1

We need to bind the blocks together using gotos. In the example the block E follows D, so we add a goto label3 after D.

 Block1
     label1:   A
               B
               if C goto label2
               D
               goto label2

  Block2    
     label2:   E
               goto label1

Now each block becomes a function and each goto becomes a tail call.

 function label1() {
               A
               B
               if C then return( label2() )
               D
               return( label2() )
 }

 function label2() {
               E
               return( label1() )
 }

To start the program, use label1().

The rewrite is purely mechanical and can thus be done with a macro system such as sweet.js if need be.

Using Quick Watch in Visual Studio you can access the LoaderExceptions from ViewDetails of the thrown exception like this:

What's the difference?

SomeBaseClass.__init__(self) 

means to call SomeBaseClass's __init__. while

super(Child, self).__init__()

means to call a bound __init__ from the parent class that follows Child in the instance's Method Resolution Order (MRO).

If the instance is a subclass of Child, there may be a different parent that comes next in the MRO.

Explained simply

When you write a class, you want other classes to be able to use it. super() makes it easier for other classes to use the class you're writing.

As Bob Martin says, a good architecture allows you to postpone decision making as long as possible.

super() can enable that sort of architecture.

When another class subclasses the class you wrote, it could also be inheriting from other classes. And those classes could have an __init__ that comes after this __init__ based on the ordering of the classes for method resolution.

Without super you would likely hard-code the parent of the class you're writing (like the example does). This would mean that you would not call the next __init__ in the MRO, and you would thus not get to reuse the code in it.

If you're writing your own code for personal use, you may not care about this distinction. But if you want others to use your code, using super is one thing that allows greater flexibility for users of the code.

Python 2 versus 3

This works in Python 2 and 3:

super(Child, self).__init__()

This only works in Python 3:

super().__init__()

It works with no arguments by moving up in the stack frame and getting the first argument to the method (usually self for an instance method or cls for a class method - but could be other names) and finding the class (e.g. Child) in the free variables (it is looked up with the name __class__ as a free closure variable in the method).

I prefer to demonstrate the cross-compatible way of using super, but if you are only using Python 3, you can call it with no arguments.

Indirection with Forward Compatibility

What does it give you? For single inheritance, the examples from the question are practically identical from a static analysis point of view. However, using super gives you a layer of indirection with forward compatibility.

Forward compatibility is very important to seasoned developers. You want your code to keep working with minimal changes as you change it. When you look at your revision history, you want to see precisely what changed when.

You may start off with single inheritance, but if you decide to add another base class, you only have to change the line with the bases - if the bases change in a class you inherit from (say a mixin is added) you'd change nothing in this class. Particularly in Python 2, getting the arguments to super and the correct method arguments right can be difficult. If you know you're using super correctly with single inheritance, that makes debugging less difficult going forward.

Dependency Injection

Other people can use your code and inject parents into the method resolution:

class SomeBaseClass(object):
    def __init__(self):
        print('SomeBaseClass.__init__(self) called')

class UnsuperChild(SomeBaseClass):
    def __init__(self):
        print('UnsuperChild.__init__(self) called')
        SomeBaseClass.__init__(self)

class SuperChild(SomeBaseClass):
    def __init__(self):
        print('SuperChild.__init__(self) called')
        super(SuperChild, self).__init__()

Say you add another class to your object, and want to inject a class between Foo and Bar (for testing or some other reason):

class InjectMe(SomeBaseClass):
    def __init__(self):
        print('InjectMe.__init__(self) called')
        super(InjectMe, self).__init__()

class UnsuperInjector(UnsuperChild, InjectMe): pass

class SuperInjector(SuperChild, InjectMe): pass

Using the un-super child fails to inject the dependency because the child you're using has hard-coded the method to be called after its own:

>>> o = UnsuperInjector()
UnsuperChild.__init__(self) called
SomeBaseClass.__init__(self) called

However, the class with the child that uses super can correctly inject the dependency:

>>> o2 = SuperInjector()
SuperChild.__init__(self) called
InjectMe.__init__(self) called
SomeBaseClass.__init__(self) called

Addressing a comment

Why in the world would this be useful?

Python linearizes a complicated inheritance tree via the C3 linearization algorithm to create a Method Resolution Order (MRO).

We want methods to be looked up in that order.

For a method defined in a parent to find the next one in that order without super, it would have to

1. get the mro from the instance's type
2. look for the type that defines the method
3. find the next type with the method
4. bind that method and call it with the expected arguments

The UnsuperChild should not have access to InjectMe. Why isn't the conclusion "Always avoid using super"? What am I missing here?

The UnsuperChild does not have access to InjectMe. It is the UnsuperInjector that has access to InjectMe - and yet cannot call that class's method from the method it inherits from UnsuperChild.

Both Child classes intend to call a method by the same name that comes next in the MRO, which might be another class it was not aware of when it was created.

The one without super hard-codes its parent's method - thus is has restricted the behavior of its method, and subclasses cannot inject functionality in the call chain.

The one with super has greater flexibility. The call chain for the methods can be intercepted and functionality injected.

You may not need that functionality, but subclassers of your code may.

Conclusion

Always use super to reference the parent class instead of hard-coding it.

What you intend is to reference the parent class that is next-in-line, not specifically the one you see the child inheriting from.

Not using super can put unnecessary constraints on users of your code.

EGit is still in eclipse incubation. You can install it using the Eclipse update manager.

1. Select Help -> Install New Software...
2. You probably do not have the JGit update URL in your list of sites so in the 'Work with:' field enter this url: http://www.jgit.org/updates
3. Click Add...
4. You should now see Eclipse Git Plugin - Integration Build (Incubation) listed as available software to install. Check it and click Next.
5. Click Next and agree to the license and it should be installed.

You can use this function I wrote. You call GetTimeMs64(), and it returns the number of milliseconds elapsed since the unix epoch using the system clock - the just like time(NULL), except in milliseconds.

It works on both windows and linux; it is thread safe.

Note that the granularity is 15 ms on windows; on linux it is implementation dependent, but it usually 15 ms as well.

/* Remove if already defined */
typedef long long int64; typedef unsigned long long uint64;

/* Returns the amount of milliseconds elapsed since the UNIX epoch. Works on both
 * windows and linux. */

uint64 GetTimeMs64()
{
#ifdef _WIN32
 /* Windows */
 FILETIME ft;
 LARGE_INTEGER li;

 /* Get the amount of 100 nano seconds intervals elapsed since January 1, 1601 (UTC) and copy it

 GetSystemTimeAsFileTime(&ft);
 li.LowPart = ft.dwLowDateTime;
 li.HighPart = ft.dwHighDateTime;

 uint64 ret = li.QuadPart;
 ret -= 116444736000000000LL; /* Convert from file time to UNIX epoch time. */
 ret /= 10000; /* From 100 nano seconds (10^-7) to 1 millisecond (10^-3) intervals */

There is a file in your git root directory named .gitignore. It's a file, not a command. You just need to insert the names of the files that you want to ignore, and they will automatically be ignored. For example, if you wanted to ignore all emacs autosave files, which end in ~, then you could add this line:

*~

If you want to remove the unwanted files from your branch, you can use git add -A, which "removes files that are no longer in the working tree".

Note: What I called the "git root directory" is simply the directory in which you used git init for the first time. It is also where you can find the .git directory.

In Python 3.2+, stdlib concurrent.futures module provides a higher level API to threading, including passing return values or exceptions from a worker thread back to the main thread:

import concurrent.futures

def foo(bar):
    print('hello {}'.format(bar))
    return 'foo'

with concurrent.futures.ThreadPoolExecutor() as executor:
    future = executor.submit(foo, 'world!')
    return_value = future.result()
    print(return_value)

Background cron job sounds like a good idea for this.

You'll need ssh access to the machine to run the script as a cron.

$ php scriptname.php to run it.

Since you want to append elements to existing list, you can use var List[Int] and then keep on adding elements to the same list. Note -> You have to make sure that you insert an element into existing list as follows:-

var l: List[int] = List() // creates an empty list

l = 3 :: l // adds 3 to the head of the list

l = 4 :: l // makes int 4 as the head of the list

// Now when you will print l, you will see two elements in the list ( 4, 3)

The problem with Javascript's MIME type is that there hasn't been a standard for years. Now we've got application/javascript as an official MIME type.

But actually, the MIME type doesn't matter at all, as the browser can determine the type itself. That's why the HTML5 specs state that the type="text/javascript" is no longer required.

Based on the answer of massimo virgilio, I've also managed to do it with slf4j-log4j using introspection. HTH.

Logger LOG = LoggerFactory.getLogger(MyOwnClass.class);

org.apache.logging.slf4j.Log4jLogger LOGGER = (org.apache.logging.slf4j.Log4jLogger) LOG;

try {
    Class loggerIntrospected = LOGGER.getClass();
    Field fields[] = loggerIntrospected.getDeclaredFields();
    for (int i = 0; i < fields.length; i++) {
        String fieldName = fields[i].getName();
        if (fieldName.equals("logger")) {
            fields[i].setAccessible(true);
            org.apache.logging.log4j.core.Logger loggerImpl = (org.apache.logging.log4j.core.Logger) fields[i].get(LOGGER);
            loggerImpl.setLevel(Level.DEBUG);
        }
    }
} catch (Exception e) {
    System.out.println("ERROR :" + e.getMessage());
}

Windows

Some of the above values are easily available from the appropriate WIN32 API, I just list them here for completeness. Others, however, need to be obtained from the Performance Data Helper library (PDH), which is a bit "unintuitive" and takes a lot of painful trial and error to get to work. (At least it took me quite a while, perhaps I've been only a bit stupid...)

Linux

On Linux the choice that seemed obvious at first was to use the POSIX APIs like getrusage() etc. I spent some time trying to get this to work, but never got meaningful values. When I finally checked the kernel sources themselves, I found out that apparently these APIs are not yet completely implemented as of Linux kernel 2.6!?

In the end I got all values via a combination of reading the pseudo-filesystem /proc and kernel calls.

TODO: Other Platforms

I would assume, that some of the Linux code also works for the Unixes, except for the parts that read the /proc pseudo-filesystem. Perhaps on Unix these parts can be replaced by getrusage() and similar functions? If someone with Unix know-how could edit this answer and fill in the details?!

An important thing to note / "Bootstrap" is just a bunch of CSS rules

a fiddle

HTML

<div class="your-centered-div">
    <img src="http://placehold.it/1120x630&text=Pretend Video 560x315" alt="" />
</div>

CSS

/* key stuff */
.your-centered-div {
    width: 560px; /* you have to have a size or this method doesn't work */
    height: 315px; /* think about making these max-width instead - might give you some more responsiveness */

    position: absolute; /* positions out of the flow, but according to the nearest parent */
    top: 0; right: 0; /* confuse it i guess */
    bottom: 0; left: 0;
    margin: auto; /* make em equal */
}

Fully working jsFiddle is here.

EDIT

I mostly use this these days:

straight CSS

.centered-thing {
    position: absolute;
    margin: auto;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

if your use stylus/mixins ( you should... it's the best )

center-center()
    absolute()
    margin auto
    top 50%
    left 50%
    transform translate(-50%,-50%)

This way... you don't need to know the size of the element - and the translate is based of it's size - So, -50% of itself. Neat.

Here's the very minimum you need to get data out of a MySQL database:

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection
   ("jdbc:mysql://localhost:3306/foo", "root", "password");

Statement stmt = conn.createStatement();
stmt.execute("SELECT * FROM `FOO.BAR`");
stmt.close();
conn.close();

Add exception handling, configuration etc. to taste.

You don't need a batch file, just do this from powershell :

powershell -C "gci | % {rni $_.Name ($_.Name -replace 'Vacation2010', 'December')}"

The method below is exactly reproducible, so there's no need to run clone again if both sides were consistent, just run the script on the other side too.

git log -n1 --format=%H >.git/info/grafts
git filter-branch -f
rm .git/info/grafts

If you then want to clean it up, try this script:

http://sam.nipl.net/b/git-gc-all-ferocious

I wrote a script which "kills history" for each branch in the repository:

http://sam.nipl.net/b/git-kill-history

see also: http://sam.nipl.net/b/confirm

What about?

/.*\S.*/

This means

/ = delimiter
.* = zero or more of anything but newline
\S = anything except a whitespace (newline, tab, space)

so you get
match anything but newline + something not whitespace + anything but newline

Another similar way to do it by css:

#img {  }_x000D_
#img:hover {visibility:hidden}_x000D_
#thistext {font-size:22px;color:white }_x000D_
#thistext:hover {color:black;}_x000D_
#hoverme {width:50px;height:50px;}_x000D_
_x000D_
#hoverme:hover { _x000D_
background-color:green;_x000D_
position:absolute ;_x000D_
left:300px;_x000D_
top:100px;_x000D_
width:40%;_x000D_
height:20%;_x000D_
}

<p id="hoverme"><img id="img" src="http://a.deviantart.net/avatars/l/o/lol-cat.jpg"></img><span id="thistext">LOCATZ!!!!</span></p>

Try it: http://jsfiddle.net/FdBu7/

This happened when i downloaded fabric.io on Eclipse Mars but Restarting computer solved this problem for me.

create table payment(
    user_id int(11),
    account int(11) not null,
    zip int(11) not null,
    dt date not null
);

insert into payment values
(1,123,55555,'2009-12-12'),
(1,123,66666,'2009-12-12'),
(1,123,77777,'2009-12-13'),
(2,456,77777,'2009-12-14'),
(2,456,77777,'2009-12-14'),
(2,789,77777,'2009-12-14'),
(2,789,77777,'2009-12-14');

select foo.user_id, foo.cnt from
(select user_id,count(account) as cnt, dt from payment group by account, dt) foo
where foo.cnt > 1;

Try this, it works for both node and the browser.

isNode = (typeof exports !== 'undefined') &&
(typeof module !== 'undefined') &&
(typeof module.exports !== 'undefined') &&
(typeof navigator === 'undefined' || typeof navigator.appName === 'undefined') ? true : false,
asyncIt = (isNode ? function (func) {
  process.nextTick(function () {
    func();
  });
} : function (func) {
  setTimeout(func, 5);
});

>>> any([False, False, False])
False
>>> any([False, True, False])
True
>>> all([False, True, True])
False
>>> all([True, True, True])
True

This question is very similar to Item 29 in Effective Java - "Consider typesafe heterogeneous containers." Laz's answer is the closest to Bloch's solution. However, both put and get should use the Class literal for safety. The signatures would become:

public <T extends Animal> void addFriend(String name, Class<T> type, T animal);
public <T extends Animal> T callFriend(String name, Class<T> type);

Inside both methods you should check that the parameters are sane. See Effective Java and the Class javadoc for more info.

It's work for me

private void showForgotDialog(Context c) {
        final EditText taskEditText = new EditText(c);
        AlertDialog dialog = new AlertDialog.Builder(c)
                .setTitle("Forgot Password")
                .setMessage("Enter your mobile number?")
                .setView(taskEditText)
                .setPositiveButton("Reset", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        String task = String.valueOf(taskEditText.getText());
                    }
                })
                .setNegativeButton("Cancel", null)
                .create();
        dialog.show();
    }

How to call? (Current activity name)

showForgotDialog(current_activity_name.this);

This is what I did based on some of the other answers here:

function measureText(text, font) {_x000D_
 const span = document.createElement('span');_x000D_
 span.appendChild(document.createTextNode(text));_x000D_
 Object.assign(span.style, {_x000D_
  font: font,_x000D_
  margin: '0',_x000D_
  padding: '0',_x000D_
  border: '0',_x000D_
  whiteSpace: 'nowrap'_x000D_
 });_x000D_
 document.body.appendChild(span);_x000D_
 const {width, height} = span.getBoundingClientRect();_x000D_
 span.remove();_x000D_
 return {width, height};_x000D_
}_x000D_
_x000D_
var font = "italic 100px Georgia";_x000D_
var text = "abc this is a test";_x000D_
console.log(measureText(text, font));

Or you can just make an ICollection extension like this:

 public static ICollection<T> AddRange<T>(this ICollection<T> @this, IEnumerable<T> items)
    {
        foreach(var item in items)
        {
            @this.Add(item);
        }

        return @this;
    }

Using it would be just like using it on a list:

collectionA.AddRange(IEnumerable<object> items);

If you are working with Android's MediaStore database, here is how to store an image and then display it after it is saved.

on button click write this

 Intent in = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            in.putExtra("crop", "true");
            in.putExtra("outputX", 100);
            in.putExtra("outputY", 100);
            in.putExtra("scale", true);
            in.putExtra("return-data", true);

            startActivityForResult(in, 1);

then do this in your activity

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null) {

            Bitmap bmp = (Bitmap) data.getExtras().get("data");

            img.setImageBitmap(bmp);
            btnadd.requestFocus();

            ByteArrayOutputStream baos = new ByteArrayOutputStream();
            bmp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
            byte[] b = baos.toByteArray();
            String encodedImageString = Base64.encodeToString(b, Base64.DEFAULT);

            byte[] bytarray = Base64.decode(encodedImageString, Base64.DEFAULT);
            Bitmap bmimage = BitmapFactory.decodeByteArray(bytarray, 0,
                    bytarray.length);

        }

    }

It's commonly referred to as 'shorthand' or the Ternary Operator.

$test = isset($_GET['something']) ? $_GET['something'] : '';

means

if(isset($_GET['something'])) {
    $test = $_GET['something'];
} else {
    $test = '';
}

To break it down:

$test = ... // assign variable
isset(...) // test
? ... // if test is true, do ... (equivalent to if)
: ... // otherwise... (equivalent to else)

Or...

// test --v
if(isset(...)) { // if test is true, do ... (equivalent to ?)
    $test = // assign variable
} else { // otherwise... (equivalent to :)

Simply:

DATE_FORMAT(FROM_DAYS(TO_DAYS(NOW())-TO_DAYS(`birthDate`)), '%Y')+0 AS age

You can Intersect the two lists:

if (A.Intersect(B).Any())

There's a more convenient way to store passwords in a script but you will have to encrypt and obfuscate the script so that it cannot be read. In order to successfully encrypt and obfuscate a shell script and actually have that script be executable, try copying and pasting it here:

http://www.kinglazy.com/shell-script-encryption-kinglazy-shieldx.htm

On the above page, all you have to do is submit your script and give the script a proper name, then hit the download button. A zip file will be generated for you. Right click on the download link and copy the URL you're provided. Then, go to your UNIX box and perform the following steps.

Installation:

1. wget link-to-the-zip-file
2. unzip the-newly-downloaded-zip-file
3. cd /tmp/KingLazySHIELD
4. ./install.sh /var/tmp/KINGLAZY/SHIELDX-(your-script-name) /home/(your-username) -force

What the above install command will do for you is:

1. Install the encrypted version of your script in the directory /var/tmp/KINGLAZY/SHIELDX-(your-script-name).
2. It'll place a link to this encrypted script in whichever directory you specify in replacement of /home/(your-username) - that way, it allows you to easily access the script without having to type the absolute path.
3. Ensures NO ONE can modify the script - Any attempts to modify the encrypted script will render it inoperable...until those attempts are stopped or removed. It can even be configured to notify you whenever someone tries to do anything with the script other than run it...i.e. hacking or modification attempts.
4. Ensures absolutely NO ONE can make copies of it. No one can copy your script to a secluded location and try to screw around with it to see how it works. All copies of the script must be links to the original location which you specified during install (step 4).

NOTE:

This does not work for interactive scripts that prompts and waits on the user for a response. The values that are expected from the user should be hard-coded into the script. The encryption ensures no one can actually see those values so you need not worry about that.

RELATION:

The solution provided in this post answers your problem in the sense that it encrypts the actual script containing the password that you wanted to have encrypted. You get to leave the password as is (unencrypted) but the script that the password is in is so deeply obfuscated and encrypted that you can rest assured no one will be able to see it. And if attempts are made to try to pry into the script, you will receive email notifications about them.

Map<Integer, Point2D> hm = new HashMap<Integer, Point2D>();

For people having a startTime (like 12h:30:30) and a duration (value in minutes like 120), you can guess the endTime like so:

const startTime = '12:30:00';
const durationInMinutes = '120';

const endTime = moment(startTime, 'HH:mm:ss').add(durationInMinutes, 'minutes').format('HH:mm');

// endTime is equal to "14:30"

it happen to me i was running it on API 23 and i had to use the code to request permission like this code below put it on on create method. note that MY_PERMISSIONS_REQUEST_READ_LOCATION is an integer that is equal to 1 example int MY_PERMISSIONS_REQUEST_READ_LOCATION = 1:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { requestPermissions(new String[]{ Manifest.permission.ACCESS_COARSE_LOCATION},MY_PERMISSIONS_REQUEST_READ_LOCATION); }

Here's an easy way without ifelse:

(a/sum(a))^(a>0)

An example:

a <- c(0, 1, 0, 0, 1, 1, 0, 1)

(a/sum(a))^(a>0)

[1] 1.00 0.25 1.00 1.00 0.25 0.25 1.00 0.25
