Try

rows = tabDelimitedTable.split("[" + newLine + "]");

This should solve the regex problem.

Also not that important but return type of

System.getProperty("line.separator")

is String so no need to call toString().

try this:

(for /f "delims=" %i in (file.unix) do @echo %i)>file.dos

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)

Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....

However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.

As you're partially working on Linux and Windows, make sure core.eol is set to native and core.autocrlf is set to true.

Then, replace the content of your .gitattributes file with the following

* text=auto

This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.

However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.

Provided you work on a C based image processing project, replace the content of your .gitattributes file with the following

* text=auto
*.txt text
*.c text
*.h text
*.jpg binary

This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.

In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.

As a real world example, you can also peek at this commit where those changes to a .gitattributes file are demonstrated.

UPDATE to the answer considering the following comment

I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory

Makes sense. Thanks for the clarification. In this specific context, the .gitattributes file by itself won't be enough.

Run the following commands against your repository

$ git config core.eol lf
$ git config core.autocrlf input

As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol will make sure text files bear LF line endings on checkouts. core.autocrlf will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.

Optionally, you can help Git distinguish what is a text file by creating a .gitattributes file containing something similar to the following:

# Autodetect text files
* text=auto

# ...Unless the name matches the following
# overriding patterns

# Definitively text files 
*.txt text
*.c text
*.h text

# Ensure those won't be messed up with
*.jpg binary
*.data binary

If you decided to create a .gitattributes file, commit it.

Lastly, ensure git status mentions "nothing to commit (working directory clean)", then perform the following operation

$ git checkout-index --force --all

This will recreate your files in your working directory, taking into account your config changes and the .gitattributes file and replacing any potential overlooked CRLF in your text files.

Once this is done, every text file in your working directory WILL bear LF line endings and git status should still consider the workdir as clean.

For a new document: Settings -> Preferences -> New Document/Default Directory -> New Document -> Format -> Windows/Mac/Unix

And for an already-open document: Edit -> EOL Conversion

Two alternative strategies to get consistent about line-endings in mixed environments (Microsoft + Linux + Mac):

A. Global per All Repositories Setup

1) Convert all to one format

find . -type f -not -path "./.git/*" -exec dos2unix {} \;
git commit -a -m 'dos2unix conversion'

2) Set core.autocrlf to input on Linux/UNIX or true on MS Windows (repository or global)

git config --global core.autocrlf input

3) [ Optional ] set core.safecrlf to true (to stop) or warn (to sing:) to add extra guard comparing if the reversed newline transformation would result in the same file

git config --global core.safecrlf true

B. Or per Repository Setup

1) Convert all to one format

find . -type f -not -path "./.git/*" -exec dos2unix {} \;
git commit -a -m 'dos2unix conversion'

2) add .gitattributes file to your repository

echo "* text=auto" > .gitattributes
git add .gitattributes
git commit -m 'adding .gitattributes for unified line-ending'

Don't worry about your binary files - Git should be smart enough about them.

More about safecrlf/autocrlf variables

Java only knows about the platform it is currently running on, so it can only give you a platform-dependent output on that platform (using bw.newLine()) . The fact that you open it on a windows system means that you either have to convert the file before using it (using something you have written, or using a program like unix2dos), or you have to output the file with windows format carriage returns in it originally in your Java program. So if you know the file will always be opened on a windows machine, you will have to output

bw.write(rs.getString(1)==null? "":rs.getString(1));
bw.write("\r\n");

It's worth noting that you aren't going to be able to output a file that will look correct on both platforms if it is just plain text you are using, you may want to consider using html if it is an email, or xml if it is data. Alternatively, you may need some kind of client that reads the data and then formats it for the platform that the viewer is using.

That functionality is already built into Notepad++. From the "Edit" menu, select "EOL Conversion" -> "UNIX/OSX Format".

screenshot of the option for even quicker finding (or different language versions)

You can also set the default EOL in notepad++ via "Settings" -> "Preferences" -> "New Document/Default Directory" then select "Unix/OSX" under the Format box.

You use PHP_EOL when you want a new line, and you want to be cross-platform.

This could be when you are writing files to the filesystem (logs, exports, other).

You could use it if you want your generated HTML to be readable. So you might follow your <br /> with a PHP_EOL.

You would use it if you are running php as a script from cron and you needed to output something and have it be formatted for a screen.

You might use it if you are building up an email to send that needed some formatting.

You can use

System.getProperty("line.separator");

to get the line separator

This is a state-of-the-union answer as of Windows PowerShell v5.1 / PowerShell Core v6.2.0:

• Andrew Savinykh's ill-fated answer, despite being the accepted one, is, as of this writing, fundamentally flawed (I do hope it gets fixed - there's enough information in the comments - and in the edit history - to do so).

• Ansgar Wiecher's helpful answer works well, but requires direct use of the .NET Framework (and reads the entire file into memory, though that could be changed). Direct use of the .NET Framework is not a problem per se, but is harder to master for novices and hard to remember in general.

• A future version of PowerShell Core will have a
  Convert-TextFile cmdlet with a -LineEnding parameter to allow in-place updating of text files with a specific newline style, as being discussed on GitHub.

In PSv5+, PowerShell-native solutions are now possible, because Set-Content now supports the -NoNewline switch, which prevents undesired appending of a platform-native newline^[1] :

# Convert CRLFs to LFs only.
# Note:
#  * (...) around Get-Content ensures that $file is read *in full*
#    up front, so that it is possible to write back the transformed content
#    to the same file.
#  * + "`n" ensures that the file has a *trailing LF*, which Unix platforms
#     expect.
((Get-Content $file) -join "`n") + "`n" | Set-Content -NoNewline $file

The above relies on Get-Content's ability to read a text file that uses any combination of CR-only, CRLF, and LF-only newlines line by line.

Caveats:

• You need to specify the output encoding to match the input file's in order to recreate it with the same encoding. The command above does NOT specify an output encoding; to do so, use -Encoding; without -Encoding:

  • In Windows PowerShell, you'll get "ANSI" encoding, your system's single-byte, 8-bit legacy encoding, such as Windows-1252 on US-English systems.
  • In PowerShell Core, you'll get UTF-8 encoding without a BOM.

• The input file's content as well as its transformed copy must fit into memory as a whole, which can be problematic with large input files.

• There's a risk of file corruption, if the process of writing back to the input file gets interrupted.

^{[1] In fact, if there are multiple strings to write, -NoNewline also doesn't place a newline between them; in the case at hand, however, this is irrelevant, because only one string is written.}

Yes, it means "not equal", either less than or greater than. e.g

If x <> y Then

can be read as

if x is less than y or x is greater than y then

The logical outcome being "If x is anything except equal to y"

s3cmd can show you this by running s3cmd du, optionally passing the bucket name as an argument.

Have you considered using stringstreams?

#include <string>
#include <sstream>

std::ostringstream oss;
oss << "sometext" << somevar << "sometext" << somevar;
std::string var = oss.str();

Assuming you want to check that all characters in the string are digits, you could use the Enumerable.All Extension Method with the Char.IsDigit Method as follows:

bool allCharactersInStringAreDigits = myStringVariable.All(char.IsDigit);

RESTful Resource controller

A RESTful resource controller sets up some default routes for you and even names them.

Route::resource('users', 'UsersController');

Gives you these named routes:

Verb          Path                        Action  Route Name
GET           /users                      index   users.index
GET           /users/create               create  users.create
POST          /users                      store   users.store
GET           /users/{user}               show    users.show
GET           /users/{user}/edit          edit    users.edit
PUT|PATCH     /users/{user}               update  users.update
DELETE        /users/{user}               destroy users.destroy

And you would set up your controller something like this (actions = methods)

class UsersController extends BaseController {

    public function index() {}

    public function show($id) {}

    public function store() {}

}

You can also choose what actions are included or excluded like this:

Route::resource('users', 'UsersController', [
    'only' => ['index', 'show']
]);

Route::resource('monkeys', 'MonkeysController', [
    'except' => ['edit', 'create']
]);

API Resource controller

Laravel 5.5 added another method for dealing with routes for resource controllers. API Resource Controller acts exactly like shown above, but does not register create and edit routes. It is meant to be used for ease of mapping routes used in RESTful APIs - where you typically do not have any kind of data located in create nor edit methods.

Route::apiResource('users', 'UsersController');

RESTful Resource Controller documentation

Implicit controller

An Implicit controller is more flexible. You get routed to your controller methods based on the HTTP request type and name. However, you don't have route names defined for you and it will catch all subfolders for the same route.

Route::controller('users', 'UserController');

Would lead you to set up the controller with a sort of RESTful naming scheme:

class UserController extends BaseController {

    public function getIndex()
    {
        // GET request to index
    }

    public function getShow($id)
    {
        // get request to 'users/show/{id}'
    }

    public function postStore()
    {
        // POST request to 'users/store'
    }

}

Implicit Controller documentation

It is good practice to use what you need, as per your preference. I personally don't like the Implicit controllers, because they can be messy, don't provide names and can be confusing when using php artisan routes. I typically use RESTful Resource controllers in combination with explicit routes.

There is a quick solution:

x = eval('[ "A","B","C" , " D"]')

Unwanted whitespaces in the list elements may be removed in this way:

x = [x.strip() for x in eval('[ "A","B","C" , " D"]')]

Procedure never returns a value.You have to use a output parameter in store procedure.

ALTER PROC TESTLOGIN
@UserName   varchar(50),
@password   varchar(50)
@retvalue int output
 as
 Begin
    declare @return     int 
    set @return  = (Select COUNT(*) 
    FROM    CPUser  
    WHERE   UserName = @UserName AND Password = @password)

   set @retvalue=@return
  End

Then you have to add a sqlparameter from c# whose parameter direction is out. Hope this make sense.

I think op wants to know what the font that is used on a webpage is, and hoped that info might be findable in the 'inspect' pane.

Try adding the Whatfont Chrome extension.

If you are going to be getting a random element multiple times, you want to make sure your random number generator is initialized only once.

import java.util.Random;

public class RandArray {
    private int[] items = new int[]{1,2,3};

    private Random rand = new Random();

    public int getRandArrayElement(){
        return items[rand.nextInt(items.length)];
    }
}

If you are picking random array elements that need to be unpredictable, you should use java.security.SecureRandom rather than Random. That ensures that if somebody knows the last few picks, they won't have an advantage in guessing the next one.

If you are looking to pick a random number from an Object array using generics, you could define a method for doing so (Source Avinash R in Random element from string array):

import java.util.Random;

public class RandArray {
    private static Random rand = new Random();

    private static <T> T randomFrom(T... items) { 
         return items[rand.nextInt(items.length)]; 
    }
}

"MMMM" is definitely NOT the right solution (even if it works for many languages), use "LLLL" pattern with SimpleDateFormat

The support for 'L' as ICU-compatible extension for stand-alone month names was added to Android platform on Jun. 2010.

Even if in English there is no difference between the encoding by 'MMMM' and 'LLLL', your should think about other languages, too.

E.g. this is what you get, if you use Calendar.getDisplayName or the "MMMM" pattern for January with the Russian Locale:

?????? (which is correct for a complete date string: "10 ??????, 2014")

but in case of a stand-alone month name you would expect:

??????

The right solution is:

 SimpleDateFormat dateFormat = new SimpleDateFormat( "LLLL", Locale.getDefault() );
 dateFormat.format( date );

If you are interested in where all the translations come from - here is the reference to gregorian calendar translations (other calendars linked on top of the page).

Use int() on a boolean test:

x = int(x == 'true')

int() turns the boolean into 1 or 0. Note that any value not equal to 'true' will result in 0 being returned.

For i = 2 To 24
  Level = Cells(i, 4)
  Return = Cells(i, 5)

  If Return = 0 And Level = 0 Then GoTo NextIteration
  'Go to the next iteration
  Else
  End If
  ' This is how you make a line label in VBA - Do not use keyword or
  ' integer and end it in colon
  NextIteration:
Next

The $PWD is a good option by Matthew above. If you want find to only print files then you can also add the -type f option to search only normal files. Other options are "d" for directories only etc. So in your case it would be (if i want to search only for files with .c ext):

find $PWD -type f -name "*.c" 

or if you want all files:

find $PWD -type f

Note: You can't make an alias for the above command, because $PWD gets auto-completed to your home directory when the alias is being set by bash.

Python's sets (and dictionaries) will iterate and print out in some order, but exactly what that order will be is arbitrary, and not guaranteed to remain the same after additions and removals.

Here's an example of a set changing order after a lot of values are added and then removed:

>>> s = set([1,6,8])
>>> print(s)
{8, 1, 6}
>>> s.update(range(10,100000))
>>> for v in range(10, 100000):
    s.remove(v)
>>> print(s)
{1, 6, 8}

This is implementation dependent though, and so you should not rely upon it.

I know notepad++ has a feature that lets you select blocks of text independent of line/column by holding control + alt + drag. So you can select just about any block of text you want.

Python compiles the .py and saves files as .pyc so it can reference them in subsequent invocations.

There's no harm in deleting them, but they will save compilation time if you're doing lots of processing.

Here is one that I have been using: -

[<1000000]0.00," KB";[<1000000000]0.00,," MB";0.00,,," GB"

Seems to work fine.

I would try to save my object as .txt file and then fetch it like this:

 $.get('yourJsonFileAsString.txt', function(data) {
   console.log( $.parseJSON( data ) );
 }); 

Count distinct values, use nunique:

df['hID'].nunique()
5

Count only non-null values, use count:

df['hID'].count()
8

Count total values including null values, use the size attribute:

df['hID'].size
8

Edit to add condition

Use boolean indexing:

df.loc[df['mID']=='A','hID'].agg(['nunique','count','size'])

OR using query:

df.query('mID == "A"')['hID'].agg(['nunique','count','size'])

Output:

nunique    5
count      5
size       5
Name: hID, dtype: int64

You could use Trigger.io's UI module to use the native Android date / time picker with a regular HTML5 input. Doing that does require using the overall framework though (so won't work as a regular mobile web page).

You can see before and after screenshots in this blog post: date time picker

Since Android Studio uses the new Gradle-based build system, you should be putting assets/ inside of the source sets (e.g., src/main/assets/).

In a typical Android Studio project, you will have an app/ module, with a main/ sourceset (app/src/main/ off of the project root), and so your primary assets would go in app/src/main/assets/. However:

• If you need assets specific to a build type, such as debug versus release, you can create sourcesets for those roles (e.g,. app/src/release/assets/)

• Your product flavors can also have sourcesets with assets (e.g., app/src/googleplay/assets/)

• Your instrumentation tests can have an androidTest sourceset with custom assets (e.g., app/src/androidTest/assets/), though be sure to ask the InstrumentationRegistry for getContext(), not getTargetContext(), to access those assets

Also, a quick reminder: assets are read-only at runtime. Use internal storage, external storage, or the Storage Access Framework for read/write content.

There is, however, no guarantee that the output of SDTOUT and STDERR are interweaved line-by-line in timely order, using the POSIX redirect merge syntax.

If an application uses buffered output, it may happen that the text of one stream is inserted in the other at a buffer boundary, which may appear in the middle of a text line.

A dedicated console output logger (I.e. the "StdOut/StdErr Logger" by 'LoRd MuldeR') may be more reliable for such a task.

See: MuldeR's OpenSource Projects

Javascript programming language supports functional programming paradigm so you can do easily with these codes.

var data = [
    {"Id": "1", "Status": "Valid"},
    {"Id": "2", "Status": "Invalid"}
];
var isValid = function(data){
    return data.Status === "Valid";
};
var valids = data.filter(isValid);

In jQuery i've made it in a such way:

len = function(obj) {
    var L=0;
    $.each(obj, function(i, elem) {
        L++;
    });
    return L;
}

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">
              <ContentPresenter.LayoutTransform>
            <RotateTransform Angle="270" />
          </ContentPresenter.LayoutTransform>
        </ContentPresenter>
          </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsSelected" Value="True">
            <Setter Property="Panel.ZIndex" Value="100" />
            <Setter TargetName="Border" Property="Background" Value="Red" />
            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
          </Trigger>
          <Trigger Property="IsEnabled" Value="False">
            <Setter TargetName="Border" Property="Background" Value="DarkRed" />
            <Setter TargetName="Border" Property="BorderBrush" Value="Black" />
            <Setter Property="Foreground" Value="DarkGray" />

Put simply

• & means the address-of, you will see that in placeholders for functions to modify the parameter variable as in C, parameter variables are passed by value, using the ampersand means to pass by reference.
• * means the dereference of a pointer variable, meaning to get the value of that pointer variable.

int foo(int *x){
   *x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(&y);  // Now y is incremented and in scope here
   printf("value of y = %d\n", y); // output is 6
   /* ... */
}

The above example illustrates how to call a function foo by using pass-by-reference, compare with this

int foo(int x){
   x++;
}

int main(int argc, char **argv){
   int y = 5;
   foo(y);  // Now y is still 5
   printf("value of y = %d\n", y); // output is 5
   /* ... */
}

Here's an illustration of using a dereference

int main(int argc, char **argv){
   int y = 5;
   int *p = NULL;
   p = &y;
   printf("value of *p = %d\n", *p); // output is 5
}

The above illustrates how we got the address-of y and assigned it to the pointer variable p. Then we dereference p by attaching the * to the front of it to obtain the value of p, i.e. *p.

You could always do it recursively like so:

void freeList(struct node* currentNode)
{
    if(currentNode->next) freeList(currentNode->next);
    free(currentNode);
}

Edit -- just saw your comment about the performance problems associated with a potentially bad piece of input data. I don't know offhand how try/catch on parseInt compares to a regex. I would guess, based on very little hard knowledge, that regexes are not hugely performant, compared to try/catch, in Java.

Anyway, I'd just do this:

public Integer tryParse(Object obj) {
  Integer retVal;
  try {
    retVal = Integer.parseInt((String) obj);
  } catch (NumberFormatException nfe) {
    retVal = 0; // or null if that is your preference
  }
  return retVal;
}

is it possible to export without looping through all records

For a range in Excel with a large number of rows you may see some performance improvement if you create an Access.Application object in Excel and then use it to import the Excel data into Access. The code below is in a VBA module in the same Excel document that contains the following test data

Option Explicit

Sub AccImport()
    Dim acc As New Access.Application
    acc.OpenCurrentDatabase "C:\Users\Public\Database1.accdb"
    acc.DoCmd.TransferSpreadsheet _
            TransferType:=acImport, _
            SpreadSheetType:=acSpreadsheetTypeExcel12Xml, _
            TableName:="tblExcelImport", _

Here's the signature.

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

What you are doing is mixing the values and the htmlAttributes together. values are for URL routing.

You might want to do this.

@Html.ActionLink(Context.User.Identity.Name, "Index", "Account", null, 
     new { @style="text-transform:capitalize;" });

It is prohibiting the opening of Eclipse app because it was not registered with Apple by an identified developer. This is a security feature, however, you can override the security setting and open the app by doing the following:

1. Locate the Eclipse.app (eclipse/Eclipse.app) in Finder. (Make sure you use Finder so that you can perform the subsequent steps.)
2. Press the Control key and then click the Eclipse.app icon.
3. Choose Open from the shortcut menu.
4. Click the Open button when the alert window appears.

The last step will add an exception for Eclipse to your security settings and now you will be able to open it without any warnings.

Note, these steps work for other *.app apps that may encounter the same issue.

//Create our own namespaces for the output
XmlSerializerNamespaces ns = new XmlSerializerNamespaces();

//Add an empty namespace and empty value

//Serialize the object with our own namespaces (notice the overload)
slz.Serialize(myXmlTextWriter, someObject, ns)

Assuming you are looking out in Winform, there is a SelectedIndexChanged event for the tab

Now in it you could check for your specific tab and proceed with the logic

private void tab1_SelectedIndexChanged(object sender, EventArgs e)
{
     if (tab1.SelectedTab == tab1.TabPages["tabname"])//your specific tabname
     {
         // your stuff
     }
}

update: Copied material that was on the R wiki at http://rwiki.sciviews.org/doku.php?id=tips:graphics-base:2yaxes, link now broken: also available from the wayback machine

Two different y axes on the same plot

(some material originally by Daniel Rajdl 2006/03/31 15:26)

Please note that there are very few situations where it is appropriate to use two different scales on the same plot. It is very easy to mislead the viewer of the graphic. Check the following two examples and comments on this issue (example1, example2 from Junk Charts), as well as this article by Stephen Few (which concludes “I certainly cannot conclude, once and for all, that graphs with dual-scaled axes are never useful; only that I cannot think of a situation that warrants them in light of other, better solutions.”) Also see point #4 in this cartoon ...

If you are determined, the basic recipe is to create your first plot, set par(new=TRUE) to prevent R from clearing the graphics device, creating the second plot with axes=FALSE (and setting xlab and ylab to be blank – ann=FALSE should also work) and then using axis(side=4) to add a new axis on the right-hand side, and mtext(...,side=4) to add an axis label on the right-hand side. Here is an example using a little bit of made-up data:

set.seed(101)
x <- 1:10
y <- rnorm(10)
## second data set on a very different scale
z <- runif(10, min=1000, max=10000) 
par(mar = c(5, 4, 4, 4) + 0.3)  # Leave space for z axis
plot(x, y) # first plot
par(new = TRUE)
plot(x, z, type = "l", axes = FALSE, bty = "n", xlab = "", ylab = "")
axis(side=4, at = pretty(range(z)))
mtext("z", side=4, line=3)

twoord.plot() in the plotrix package automates this process, as does doubleYScale() in the latticeExtra package.

Another example (adapted from an R mailing list post by Robert W. Baer):

## set up some fake test data
time <- seq(0,72,12)
betagal.abs <- c(0.05,0.18,0.25,0.31,0.32,0.34,0.35)
cell.density <- c(0,1000,2000,3000,4000,5000,6000)

## add extra space to right margin of plot within frame
par(mar=c(5, 4, 4, 6) + 0.1)

## Plot first set of data and draw its axis
plot(time, betagal.abs, pch=16, axes=FALSE, ylim=c(0,1), xlab="", ylab="", 
   type="b",col="black", main="Mike's test data")
axis(2, ylim=c(0,1),col="black",las=1)  ## las=1 makes horizontal labels
mtext("Beta Gal Absorbance",side=2,line=2.5)
box()

## Allow a second plot on the same graph
par(new=TRUE)

## Plot the second plot and put axis scale on right
plot(time, cell.density, pch=15,  xlab="", ylab="", ylim=c(0,7000), 
    axes=FALSE, type="b", col="red")
## a little farther out (line=4) to make room for labels
mtext("Cell Density",side=4,col="red",line=4) 
axis(4, ylim=c(0,7000), col="red",col.axis="red",las=1)

## Draw the time axis
axis(1,pretty(range(time),10))
mtext("Time (Hours)",side=1,col="black",line=2.5)  

## Add Legend
legend("topleft",legend=c("Beta Gal","Cell Density"),
  text.col=c("black","red"),pch=c(16,15),col=c("black","red"))

Similar recipes can be used to superimpose plots of different types – bar plots, histograms, etc..

Just to complete the answer (using the KeyEvent is the way to go) but up arrow is 38 and down arrow is 40 so:

    else if (e.getKeyCode()==38)
    {
            //Up arrow key code
    }
    else if (e.getKeyCode()==40)
    {
            //down arrow key code
    }

Sure, that is why python implements the following methods where the first parameter is a function:

• map(function, iterable, ...) - Apply function to every item of iterable and return a list of the results.
• filter(function, iterable) - Construct a list from those elements of iterable for which function returns true.
• reduce(function, iterable[,initializer]) - Apply function of two arguments cumulatively to the items of iterable, from left to right, so as to reduce the iterable to a single value.
• lambdas

You basically need to do this:

• include the target hash into the link pointing to the other page (href="other_page.html#section")
• in your ready handler clear the hard jump scroll normally dictated by the hash and as soon as possible scroll the page back to the top and call jump() - you'll need to do this asynchronously
• in jump() if no event is given, make location.hash the target
• also this technique might not catch the jump in time, so you'll better hide the html,body right away and show it back once you scrolled it back to zero

This is your code with the above added:

var jump=function(e)
{
   if (e){
       e.preventDefault();
       var target = $(this).attr("href");
   }else{
       var target = location.hash;
   }

   $('html,body').animate(
   {
       scrollTop: $(target).offset().top
   },2000,function()
   {
       location.hash = target;
   });

}

$('html, body').hide();

$(document).ready(function()
{
    $('a[href^=#]').bind("click", jump);

    if (location.hash){
        setTimeout(function(){
            $('html, body').scrollTop(0).show();
            jump();
        }, 0);
    }else{
        $('html, body').show();
    }
});

Verified working in Chrome/Safari, Firefox and Opera. I don't know about IE though.

If you can use JQuery, then using the JQuery :focus selector will do the needful

$(this).is(':focus');

Python 2

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u prefix on strings, i.e. u'€' or by decoding a string with mystr.decode('utf-8') using the appropriate encoding.

The best practice is to decode all text data as it's read, rather than decoding mid-program. The io module provides an open() method which decodes text data to Unicode strings as it's read.

ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write() method.

Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write() and adds the relevant header.

Presuming your input file is UTF-8 encoded (0xC2 is common UTF-8 lead byte), putting everything together, and using the with statement, your code should look like:

with io.open('myText.txt', "r", encoding='utf-8') as f:
    data = f.read()

root = ET.Element("add")
doc = ET.SubElement(root, "doc")

field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data

tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)

Output:

<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>

int g[] = {9,8};

This declares an object of type int[2], and initializes its elements to {9,8}

int (*j) = g;

This declares an object of type int *, and initializes it with a pointer to the first element of g.

The fact that the second declaration initializes j with something other than g is pretty strange. C and C++ just have these weird rules about arrays, and this is one of them. Here the expression g is implicitly converted from an lvalue referring to the object g into an rvalue of type int* that points at the first element of g.

This conversion happens in several places. In fact it occurs when you do g[0]. The array index operator doesn't actually work on arrays, only on pointers. So the statement int x = j[0]; works because g[0] happens to do that same implicit conversion that was done when j was initialized.

A pointer to an array is declared like this

int (*k)[2];

and you're exactly right about how this would be used

int x = (*k)[0];

(note how "declaration follows use", i.e. the syntax for declaring a variable of a type mimics the syntax for using a variable of that type.)

However one doesn't typically use a pointer to an array. The whole purpose of the special rules around arrays is so that you can use a pointer to an array element as though it were an array. So idiomatic C generally doesn't care that arrays and pointers aren't the same thing, and the rules prevent you from doing much of anything useful directly with arrays. (for example you can't copy an array like: int g[2] = {1,2}; int h[2]; h = g;)

Examples:

void foo(int c[10]); // looks like we're taking an array by value.
// Wrong, the parameter type is 'adjusted' to be int*

int bar[3] = {1,2};
foo(bar); // compile error due to wrong types (int[3] vs. int[10])?
// No, compiles fine but you'll probably get undefined behavior at runtime

// if you want type checking, you can pass arrays by reference (or just use std::array):
void foo2(int (&c)[10]); // paramater type isn't 'adjusted'
foo2(bar); // compiler error, cannot convert int[3] to int (&)[10]

int baz()[10]; // returning an array by value?
// No, return types are prohibited from being an array.

int g[2] = {1,2};
int h[2] = g; // initializing the array? No, initializing an array requires {} syntax
h = g; // copying an array? No, assigning to arrays is prohibited

Because arrays are so inconsistent with the other types in C and C++ you should just avoid them. C++ has std::array that is much more consistent and you should use it when you need statically sized arrays. If you need dynamically sized arrays your first option is std::vector.

getElementById("id").removeAttribute("style");

if you are using jQuery then

$("#id").removeClass("classname");

Ok, I'll take a stab at this. If you want to work with PHP, you will need to install and configure both PHP and a webserver on your machine. This article might get you started: PHP Manual: Installation on Windows systems

Once you have your environment setup, you can start working with webforms. Directly From the article: Processing form data with PHP:

For this example you will need to create two pages. On the first page we will create a simple HTML form to collect some data. Here is an example:

<html>   
<head>
 <title>Test Page</title>
</head>   
<body>   
    <h2>Data Collection</h2><p>
    <form action="process.php" method="post">  
        <table>
            <tr>
                <td>Name:</td>
                <td><input type="text" name="Name"/></td>
            </tr>   
            <tr>
                <td>Age:</td>
                <td><input type="text" name="Age"/></td>
            </tr>   
            <tr>
                <td colspan="2" align="center">
                <input type="submit"/>
                </td>
            </tr>
        </table>
    </form>
</body>
</html>

This page will send the Name and Age data to the page process.php. Now lets create process.php to use the data from the HTML form we made:

<?php   
    print "Your name is ". $Name;   
    print "<br />";   
    print "You are ". $Age . " years old";   
    print "<br />";   $old = 25 + $Age;
    print "In 25 years you will be " . $old . " years old";   
?>

As you may be aware, if you leave out the method="post" part of the form, the URL with show the data. For example if your name is Bill Jones and you are 35 years old, our process.php page will display as http://yoursite.com/process.php?Name=Bill+Jones&Age=35 If you want, you can manually change the URL in this way and the output will change accordingly.

Additional JavaScript Example

This single file example takes the html from your question and ties the onSubmit event of the form to a JavaScript function that pulls the values of the 2 textboxes and displays them in an alert box.

Note: document.getElementById("fname").value gets the object with the ID tag that equals fname and then pulls it's value - which in this case is the text in the First Name textbox.

 <html>
    <head>
     <script type="text/javascript">
     function ExampleJS(){
        var jFirst = document.getElementById("fname").value;
        var jLast = document.getElementById("lname").value;
        alert("Your name is: " + jFirst + " " + jLast);
     }
     </script>

    </head>
    <body>
        <FORM NAME="myform" onSubmit="JavaScript:ExampleJS()">

             First name: <input type="text" id="fname" name="firstname" /><br />
             Last name:  <input type="text" id="lname" name="lastname" /><br />
            <input name="Submit"  type="submit" value="Update" />
        </FORM>
    </body>
</html>

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

instanceof is used to check if an object is an instance of a class, an instance of a subclass, or an instance of a class that implements a particular interface.

Read more from the Oracle language definition here.

yes there are some telltale signs for common CMSs like Drupal, Joomla, Pligg, and RoR etc .. .. ASP.NET stuff is easy to spot too .. but as the framework becomes more obscure it gets harder to deduce ..

What I usually is compare the site i am snooping with another site that I know is built using a particular tech. That sometimes works ..

Partly, because Go doesn't have generics (so you would need one set-type for every type, or fall back on reflection, which is rather inefficient).

Partly, because if all you need is "add/remove individual elements to a set" and "relatively space-efficient", you can get a fair bit of that simply by using a map[yourtype]bool (and set the value to true for any element in the set) or, for more space efficiency, you can use an empty struct as the value and use _, present = the_setoid[key] to check for presence.

That its the correct code of background size :

<div class="html-mobile-background">
</div>

<style type="text/css">
html {
    /* Whatever you want */
}
.html-mobile-background {
    position: fixed;
    z-index: -1;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%; /* To compensate for mobile browser address bar space */
    background: url(YOUR BACKGROUND URL HERE) no-repeat; 
 center center fixed; 
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
 background-size: 100% 100%
}
</style>

As part of your jvm arguments you can set -Dlog4j.configuration=file:"<FILE_PATH>". Where FILE_PATH is the path of your log4j.properties file.

Please note that as of log4j2, the new system variable to use is log4j.configurationFile and you put in the actual path to the file (i.e. without the file: prefix) and it will automatically load the factory based on the extension of the configuration file:

-Dlog4j.configurationFile=/path/to/log4jconfig.{ext}

    public static string GetIPAddress(string hostname)
    {
        IPHostEntry host;
        host = Dns.GetHostEntry(hostname);

        foreach (IPAddress ip in host.AddressList)
        {
            if (ip.AddressFamily == System.Net.Sockets.AddressFamily.InterNetwork)
            {
                //System.Diagnostics.Debug.WriteLine("LocalIPadress: " + ip);
                return ip.ToString();
            }
        }
        return string.Empty;
    }

HTML 5

You can use HTML5 input type number to restrict only number entries:

<input type="number" name="someid" />

This will work only in HTML5 complaint browser. Make sure your html document's doctype is:

<!DOCTYPE html>

See also https://github.com/jonstipe/number-polyfill for transparent support in older browsers.

JavaScript

Update: There is a new and very simple solution for this:

It allows you to use any kind of input filter on a text <input>, including various numeric filters. This will correctly handle Copy+Paste, Drag+Drop, keyboard shortcuts, context menu operations, non-typeable keys, and all keyboard layouts.

See this answer or try it yourself on JSFiddle.

For general purpose, you can have JS validation as below:

function isNumberKey(evt){
    var charCode = (evt.which) ? evt.which : evt.keyCode
    if (charCode > 31 && (charCode < 48 || charCode > 57))
        return false;
    return true;
}

<input name="someid" type="number" onkeypress="return isNumberKey(event)"/>

If you want to allow decimals replace the "if condition" with this:

if (charCode > 31 && (charCode != 46 &&(charCode < 48 || charCode > 57)))

Source: HTML text input allow only numeric input

I know this is an old post but as MisterZimbu stated, the color property is defining the values of other properties, as the border-color and, with CSS3, of currentColor.

currentColor is very handy if you want to use the font color for other elements (as the background or custom checkboxes and radios of inner elements for example).

Example:

.element {_x000D_
  color: green;_x000D_
  background: red;_x000D_
  display: block;_x000D_
  width: 200px;_x000D_
  height: 200px;_x000D_
  padding: 0;_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.innerElement1 {_x000D_
  border: solid 10px;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}_x000D_
_x000D_
.innerElement2 {_x000D_
  background: currentColor;_x000D_
  display: inline-block;_x000D_
  width: 60px;_x000D_
  height: 100px;_x000D_
  margin: 10px;_x000D_
}

<div class="element">_x000D_
  <div class="innerElement1"></div>_x000D_
  <div class="innerElement2"></div>_x000D_
</div>

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

// sample C#
public void populateButtons()
{
    int xPos;
    int yPos;

    Random ranNum = new Random();

    for (int i = 0; i < 50; i++)
    {
        Button foo = new Button();
        Style buttonStyle = Window.Resources["CurvedButton"] as Style;

        int sizeValue = ranNum.Next(50);

        foo.Width = sizeValue;
        foo.Height = sizeValue;
        foo.Name = "button" + i;

        xPos = ranNum.Next(300);
        yPos = ranNum.Next(200);

        foo.HorizontalAlignment = HorizontalAlignment.Left;
        foo.VerticalAlignment = VerticalAlignment.Top;
        foo.Margin = new Thickness(xPos, yPos, 0, 0);

        foo.Style = buttonStyle;

        foo.Click += new RoutedEventHandler(buttonClick);
        LayoutRoot.Children.Add(foo);
   }
}

private void buttonClick(object sender, EventArgs e)
{
  //do something or...
  Button clicked = (Button) sender;
  MessageBox.Show("Button's name is: " + clicked.Name);
}

This function will clear the sheet data starting from specified row and column :

Sub ClearWKSData(wksCur As Worksheet, iFirstRow As Integer, iFirstCol As Integer)

Dim iUsedCols As Integer
Dim iUsedRows As Integer

iUsedRows = wksCur.UsedRange.Row + wksCur.UsedRange.Rows.Count - 1
iUsedCols = wksCur.UsedRange.Column + wksCur.UsedRange.Columns.Count - 1

If iUsedRows > iFirstRow And iUsedCols > iFirstCol Then
    wksCur.Range(wksCur.Cells(iFirstRow, iFirstCol), wksCur.Cells(iUsedRows, iUsedCols)).Clear
End If

End Sub

I got it. This is very simple. Using the class bg you can achieve this easily.

Let me show you:

<nav class="navbar navbar-expand-lg navbar-dark navbar-full bg-primary"></nav>

This gives you the default blue navbar

If you want to change your favorite color, then simply use the style tag within the nav:

<nav class="navbar navbar-expand-lg navbar-dark navbar-full" style="background-color: #FF0000">

Use geom_text , with aes label. You can play with hjust, vjust to adjust text position.

ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +geom_text(aes(label=Name),hjust=0, vjust=0)

EDIT: Label only values above a certain threshold:

  ggplot(nba, aes(x= MIN, y= PTS, colour="green", label=Name))+
  geom_point() +
  geom_text(aes(label=ifelse(PTS>24,as.character(Name),'')),hjust=0,vjust=0)

You need to add below code in your AppDelegate applicationDidBecomeActive method.

[[UIApplication sharedApplication] setApplicationIconBadgeNumber: 0];

You can use the environment variable NUMBER_OF_PROCESSORS for the total number of processors:

echo %NUMBER_OF_PROCESSORS%

For me the UnicodeWriter class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row() interface.

For example:

csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

works, while:

csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)

will throw AttributeError: 'int' object has no attribute 'encode'.

As UnicodeWriter obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:

def to_utf8(lst):
    return [unicode(elem).encode('utf-8') for elem in lst]

...
csv_writer.writerow(to_utf8(row))

Or we can even monkey-patch csv_writer to add a write_utf8_row function - the exercise is left to the reader.

You'll have to make this separate try blocks:

try:
    code a
except ExplicitException:
    pass

try:
    code b
except ExplicitException:
    try:
        code c
    except ExplicitException:
        try:
            code d
        except ExplicitException:
            pass

This assumes you want to run code c only if code b failed.

If you need to run code c regardless, you need to put the try blocks one after the other:

try:
    code a
except ExplicitException:
    pass

try:
    code b
except ExplicitException:
    pass

try:
    code c
except ExplicitException:
    pass

try:
    code d
except ExplicitException:
    pass

I'm using except ExplicitException here because it is never a good practice to blindly ignore all exceptions. You'll be ignoring MemoryError, KeyboardInterrupt and SystemExit as well otherwise, which you normally do not want to ignore or intercept without some kind of re-raise or conscious reason for handling those.

I also had the same error .. I did this to fix it

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v11.0\WebApplications\Microsoft.WebApplication.targets" />

change to

<Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v12.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

and it's done.

http_get should do the trick. The advantages of http_get over file_get_contents include the ability to view HTTP headers, access request details, and control the connection timeout.

$response = http_get("http://www.example.com/file.xml");

Also,

monthly_mean.plot(x=df.index, y='A')

The CSS Lists and Counters Module Level 3 introduces the ::marker pseudo-element. From what I've understood it would allow such a thing. Unfortunately, no browser seems to support it.

What you can do is add some padding to the parent ul and pull the icon into that padding:

ul {_x000D_
  list-style: none;_x000D_
  padding: 0;_x000D_
}_x000D_
li {_x000D_
  padding-left: 1.3em;_x000D_
}_x000D_
li:before {_x000D_
  content: "\f00c"; /* FontAwesome Unicode */_x000D_
  font-family: FontAwesome;_x000D_
  display: inline-block;_x000D_
  margin-left: -1.3em; /* same as padding-left set on li */_x000D_
  width: 1.3em; /* same as padding-left set on li */_x000D_
}

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/font-awesome/4.5.0/css/font-awesome.min.css">_x000D_
<ul>_x000D_
  <li>Item one</li>_x000D_
  <li>Item two</li>_x000D_
</ul>

Adjust the padding/font-size/etc to your liking, and that's it. Here's the usual fiddle: http://jsfiddle.net/joplomacedo/a8GxZ/

=====

This works with any type of iconic font. FontAwesome, however, provides their own way to deal with this 'problem'. Check out Darrrrrren's answer below for more details.

I think the best way is:

data: "{'Ids':['2','2']}"

To read this values Ids[0], Ids[1].

This will take a json string and turn it into any class you specify

public static T ConvertJsonToClass<T>(this string json)
    {
        System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        return serializer.Deserialize<T>(json);
    }

ALTER TABLE DROP FOREIGN KEY fk_name;
ALTER TABLE ADD FOREIGN KEY fk_name(fk_cols)
            REFERENCES tbl_name(pk_names) ON DELETE RESTRICT;

In this mode you can find all element which has class active and remove it

try this

$(document).ready(function() {
        $(this.attr('id')).click(function () {
           $(document).find('.active').removeClass('active');
           var DivId = $(this).attr('id');
           alert(DivId);
           $(this).addClass('active');
        });
  });

Using C programming on a Linux variant as a base case for examples.

Lock:

• Usually a very simple construct binary in operation either locked or unlocked

• No concept of thread ownership, priority, sequencing etc.

• Usually a spin lock where the thread continuously checks for the locks availability.

• Usually relies on atomic operations e.g. Test-and-set, compare-and-swap, fetch-and-add etc.

• Usually requires hardware support for atomic operation.

File Locks:

• Usually used to coordinate access to a file via multiple processes.

• Multiple processes can hold the read lock however when any single process holds the write lock no other process is allowed to acquire a read or write lock.

• Example : flock, fcntl etc..

Mutex:

• Mutex function calls usually work in kernel space and result in system calls.

• It uses the concept of ownership. Only the thread that currently holds the mutex can unlock it.

• Mutex is not recursive (Exception: PTHREAD_MUTEX_RECURSIVE).

• Usually used in Association with Condition Variables and passed as arguments to e.g. pthread_cond_signal, pthread_cond_wait etc.

• Some UNIX systems allow mutex to be used by multiple processes although this may not be enforced on all systems.

Semaphore:

• This is a kernel maintained integer whose values is not allowed to fall below zero.

• It can be used to synchronize processes.

• The value of the semaphore may be set to a value greater than 1 in which case the value usually indicates the number of resources available.

• A semaphore whose value is restricted to 1 and 0 is referred to as a binary semaphore.

I use the object FileReader on the input onchange event for your input file type! This example uses the readAsDataURL function and for that reason you should have an tag. The FileReader object also has readAsBinaryString to get the binary data, which can later be used to create the same file on your server

Example:

var input = document.getElementById("inputFile");
var fReader = new FileReader();
fReader.readAsDataURL(input.files[0]);
fReader.onloadend = function(event){
    var img = document.getElementById("yourImgTag");
    img.src = event.target.result;
}

If you want to toggle text with a toggle button.

HTMLfile which is using bootstrap:

<input class="btn" (click)="muteStream()"  type="button"
          [ngClass]="status ? 'btn-success' : 'btn-danger'" 
          [value]="status ? 'unmute' : 'mute'"/>

TS file:

muteStream() {
   this.status = !this.status;
}

Here are some visual supplemental examples. See my fuller answer for examples of adding and removing a range.

Add single item

Add "Pig" at index 2.

String item = "Pig";
int insertIndex = 2;
data.add(insertIndex, item);
adapter.notifyItemInserted(insertIndex);

Remove single item

Remove "Pig" from the list.

int removeIndex = 2;
data.remove(removeIndex);
adapter.notifyItemRemoved(removeIndex);

On Windows, part of the mystery appears to be where npm installs the Grunt.cmd file. While on my Linux box, I just had to run sudo npm install -g grunt-cli, on my Windows 8 work laptop, Grunt was placed in the '.npm-global' directory: %USER_HOME%\.npm-global and I had to add that to the Path.

So on Windows my steps were:

• npm install -g grunt-cli

• figure out where the heck grunt.cmd was (I guess for some it is in %USER_HOME%\App_Data\Roaming)

• Added the location to my Path environment variable. Opened a new cmd prompt and the grunt command ran fine.

curl without any options will perform a GET request. It will simply return the data from the URI specified. Not retrieve the file itself to your local machine.

When you do,

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png

You will receive binary data:

                   |?>?$! <R?HP@T*?Pm?Z??jU???ZP+UAUQ@?
??{X\? K???>0c?yF[i?}4?!?V¸?H_?)nO#?;I??vg^_ ??-Hm$$N0.
???%Y[?L?U3?_^9??P?T?0'u8?l?4 ...

In order to save this, you can use:

$ curl https://www.python.org/static/apple-touch-icon-144x144-precomposed.png > image.png

to store that raw image data inside of a file.

An easier way though, is just to use wget.

$ wget https://www.python.org/static/apple-touch-icon-144x144-precomposed.png
$ ls
.
..
apple-touch-icon-144x144-precomposed.png

When you try to merge one commit with a commit that can be reached by following the first commit’s history, Git simplifies things by moving the pointer forward because there is no divergent work to merge together – this is called a “fast-forward.”

For more : http://git-scm.com/book/en/v2/Git-Branching-Basic-Branching-and-Merging

In another way,

If Master has not diverged, instead of creating a new commit, git will just point master to the latest commit of the feature branch. This is a “fast forward.”

There won't be any "merge commit" in fast-forwarding merge.

One more way without explicit route:

async reload(url: string): Promise<boolean> {
  await this.router.navigateByUrl('.', { skipLocationChange: true });
  return this.router.navigateByUrl(url);
}

Using bootstrap with a little bit of customization, the following seems to work for me:

I need 3 partitions in my container and I tried this:

CSS:

.row.content {height: 100%; width:100%; position: fixed; }
.sidenav {
  padding-top: 20px;
  border: 1px solid #cecece;
  height: 100%;
}
.midnav {
  padding: 0px;
}

HTML:

  <div class="container-fluid text-center"> 
    <div class="row content">
    <div class="col-md-2 sidenav text-left">Some content 1</div>
    <div class="col-md-9 midnav text-left">Some content 2</div>
    <div class="col-md-1 sidenav text-center">Some content 3</div>
    </div>
  </div>

Replace your jquery files with followings :

Since the currently proposed implementations which do implement a sorted list by breaking the Collection API, have an own implementation of a tree or something similar, I was curios how an implementation based on the TreeMap would perform. (Especialy since the TreeSet does base on TreeMap, too)

If someone is interested in that, too, he or she can feel free to look into it:

TreeList

Its part of the core library, you can add it via Maven dependency of course. (Apache License)

Currently the implementation seems to compare quite well on the same level than the guava SortedMultiSet and to the TreeList of the Apache Commons library.

But I would be happy if more than only me would test the implementation to be sure I did not miss something important.

Best regards!

I had this sort of error in Ionic3 (which uses Angular 4 as part of it's technology stack).

For me it was doing this:

<ion-icon [name]="getFavIconName()"></ion-icon>

So I was trying to conditionally change the type of an ion-icon from a pin to a remove-circle, per a mode a screen was operating on.

I'm guessing I'll have to add an *ngIf instead.

It is so simple, you have 2 objects with the same name and when you say: bank_holiday[month] python thinks you wanna run your function and got ERROR.

Just rename your array to bank_holidays <--- add a 's' at the end! like this:

bank_holidays= [1, 0, 1, 1, 2, 0, 0, 1, 0, 0, 0, 2] #gives the list of bank holidays in each month

def bank_holiday(month):
   if month <1 or month > 12:
       print("Error: Out of range")
       return
   print(bank_holidays[month-1],"holiday(s) in this month ")

bank_holiday(int(input("Which month would you like to check out: ")))

For me, I found the suggestion in the following thread helped:

You have to use style="width:value" with center block class

According to RFC 4337 § 2, video/mp4 is indeed the correct Content-Type for MPEG-4 video.

Generally, you can find official MIME definitions by searching for the file extension and "IETF" or "RFC". The RFC (Request for Comments) articles published by the IETF (Internet Engineering Taskforce) define many Internet standards, including MIME types.

You would do something like that using Google API.

Please note you must include the google maps library for this to work. Google geocoder returns a lot of address components so you must make an educated guess as to which one will have the city.

"administrative_area_level_1" is usually what you are looking for but sometimes locality is the city you are after.

Anyhow - more details on google response types can be found here and here.

git push can push all branches or a single one dependent on this configuration:

Push all branches

git config --global push.default matching

It will push all the branches to the remote branch and would merge them. If you don't want to push all branches, you can push the current branch if you fully specify its name, but this is much is not different from default.

Push only the current branch if its named upstream is identical

git config --global push.default simple

So, it's better, in my opinion, to use this option and push your code branch by branch. It's better to push branches manually and individually.

If your application only works in portrait orientation, this is enough:

[[[UIApplication sharedApplication] keyWindow] addSubview:yourView]

And your view will not be shown over keyboard and status bar.

If you want to get a topmost view that over keyboard or status bar, or you want the topmost view can rotate correctly with devices, please try this framework:

It supports iOS7/8/9.

sleep is a non-standard function.

• On UNIX, you shall include <unistd.h>.
• On MS-Windows, Sleep is rather from <windows.h>.

In every case, check the documentation.

tl;dr

For Spark Context you may use:

sc.setLogLevel(<logLevel>)

where loglevel can be ALL, DEBUG, ERROR, FATAL, INFO, OFF, TRACE or WARN.

Details-

Internally, setLogLevel calls org.apache.log4j.Level.toLevel(logLevel) that it then uses to set using org.apache.log4j.LogManager.getRootLogger().setLevel(level).

You may directly set the logging levels to OFF using:

LogManager.getLogger("org").setLevel(Level.OFF)

You can set up the default logging for Spark shell in conf/log4j.properties. Use conf/log4j.properties.template as a starting point.

Setting Log Levels in Spark Applications

In standalone Spark applications or while in Spark Shell session, use the following:

import org.apache.log4j.{Level, Logger}

Logger.getLogger(classOf[RackResolver]).getLevel
Logger.getLogger("org").setLevel(Level.OFF)
Logger.getLogger("akka").setLevel(Level.OFF)

Disabling logging(in log4j):

Use the following in conf/log4j.properties to disable logging completely:

log4j.logger.org=OFF

Reference: Mastering Spark by Jacek Laskowski.

Alex' comment looks good but I was still confused with using range. The following worked for me while working on a for condition using length within range.

{% for i in range(0,(nums['list_users_response']['list_users_result']['users'])| length) %}
<li>    {{ nums['list_users_response']['list_users_result']['users'][i]['user_name'] }} </li>
{% endfor %}

I believe all relevant solutions have been provided but here is a subtle situatuion: know that if you don't close and open your terminal again you will not see the effect.

Close your terminal and open then type in your terminal

yarn --version

Cheers!

No, it's doesn't give you a single executable in the sense that you only have one file afterwards - but you have a directory which contains everything you need for running your program, including an exe file.

I just wrote this setup.py today. You only need to invoke python setup.py py2exe.

We can use an optional merger function also in case of same key collision. For example, If two or more persons have the same getLast() value, we can specify how to merge the values. If we not do this, we could get IllegalStateException. Here is the example to achieve this...

Map<String, Person> map = 
roster
    .stream()
    .collect(
        Collectors.toMap(p -> p.getLast(),
                         p -> p,
                         (person1, person2) -> person1+";"+person2)
    );

if you need to call a controller from a view, maybe to load a partial view, you thinking as modular programming, and you should implement HMVC structure in lieu of plane MVC. CodeIgniter didnt implement HMVC natively, but you can use this useful library in order to implement HMVC. https://bitbucket.org/wiredesignz/codeigniter-modular-extensions-hmvc

after setup remember:that all your controllers should extends from MX_Controller in order to using this feature.

Your regex pattern should have the g modifier:

var pattern = /[somepattern]+/g;

notice the g at the end. it tells the replacer to do a global replace.

Also you dont need to use the RegExp object you can construct your pattern as above. Example pattern:

var pattern = /[0-9a-zA-Z]+/g;

a pattern is always surrounded by / on either side - with modifiers after the final /, the g modifier being the global.

EDIT: Why does it matter if pattern is a variable? In your case it would function like this (notice that pattern is still a variable):

var pattern = /[0-9a-zA-Z]+/g;
repeater.replace(pattern, "1234abc");

But you would need to change your replace function to this:

this.markup = this.markup.replace(pattern, value);

Referencing Bash Variables Requires Parameter Expansion

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

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

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

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

Javascript way:

var language = window.navigator.userLanguage || window.navigator.language;//returns value like 'en-us'

If you are using jQuery.i18n plugin, you can use:

jQuery.i18n.browserLang();//returns value like '"en-US"'

How to remove the box of the legend?

plt.legend(frameon=False)

How to change the color of the border of the legend box?

How to remove only the border of the box of the legend?

leg = plt.legend()
leg.get_frame().set_linewidth(0.0)

The problem with the after_initialize solutions is that you have to add an after_initialize to every single object you look up out of the DB, regardless of whether you access this attribute or not. I suggest a lazy-loaded approach.

The attribute methods (getters) are of course methods themselves, so you can override them and provide a default. Something like:

Class Foo < ActiveRecord::Base
  # has a DB column/field atttribute called 'status'
  def status
    (val = read_attribute(:status)).nil? ? 'ACTIVE' : val
  end
end

Unless, like someone pointed out, you need to do Foo.find_by_status('ACTIVE'). In that case I think you'd really need to set the default in your database constraints, if the DB supports it.

To check installation of CUDA, run below command, if it’s installed properly then below command will not throw any error and will print correct version of library.

function lib_installed() { /sbin/ldconfig -N -v $(sed 's/:/ /' <<< $LD_LIBRARY_PATH) 2>/dev/null | grep $1; }
function check() { lib_installed $1 && echo "$1 is installed" || echo "ERROR: $1 is NOT installed"; }
check libcuda
check libcudart

To check installation of CuDNN, run below command, if CuDNN is installed properly then you will not get any error.

function lib_installed() { /sbin/ldconfig -N -v $(sed 's/:/ /' <<< $LD_LIBRARY_PATH) 2>/dev/null | grep $1; }
function check() { lib_installed $1 && echo "$1 is installed" || echo "ERROR: $1 is NOT installed"; }
check libcudnn

Since Hashtable in Java is a subclass of Dictionary class which is now obsolete due to the existence of Map Interface, it is not used anymore. Moreover, there isn't anything you can't do with a class that implements the Map Interface that you can do with a Hashtable.

I don't know exactly what yum install java will actually install. But to check for javac existence do:

preferably as root. If it's not there you've probably only installed the Java runtime (JRE) and not the Java Development Kit (JDK). You're best off getting this from the Oracle site: as the Linux repos may be slightly behind with latest versions and also they seem to only supply the open-jdk as opposed to the Oracle/Sun one, which I would prefer given the choice.

It supports .mts and normal files like .mp4 and .avi. Tried and Tested on .mts files. Works like a Charm.

encountered same exact symptops. above worked for me.

I had two indices with unassigned shards that didn't seem to be self-healing. I eventually resolved this by temporarily adding an extra data-node^[1]. After the indices became healthy and everything stabilized to green, I removed the extra node and the system was able to rebalance (again) and settle on a healthy state.

It's a good idea to avoid killing multiple data nodes at once (which is how I got into this state). Likely, I had failed to preserve any copies/replicas for at least one of the shards. Luckily, Kubernetes kept the disk storage around, and reused it when I relaunched the data-node.

...Some time has passed...

Well, this time just adding a node didn't seem to be working (after waiting several minutes for something to happen), so I started poking around in the REST API.

GET /_cluster/allocation/explain

This showed my new node with "decision": "YES".

By the way, all of the pre-existing nodes had "decision": "NO" due to "the node is above the low watermark cluster setting". So this was probably a different case than the one I had addressed previously.

Then I made the following simple POST^[2] with no body, which kicked things into gear...

POST /_cluster/reroute

Other notes:

• Very helpful: https://datadoghq.com/blog/elasticsearch-unassigned-shards

• Something else that may work. Set cluster_concurrent_rebalance to 0, then to null -- as I demonstrate here.

Here are some practices that could avoid headaches when using Virtual Environments:

• Create a folder for your projects.
• Create your Virtualenv projects inside of this folder.
• After activating the environment of your project, never use "sudo pip install package".
• After finishing your work, always "deactivate" your environment.
• Avoid renaming your project folder.

For a better representation of this practices, here is a simulation:

creating a folder for your projects/environments

$ mkdir venv

creating environment

$ cd venv/ 

$ virtualenv google_drive

Notes:

Why not sudo?

Virtualenv creates a whole new environment for you, defining $PATH and some other variables and settings. When you use sudo pip install package, you are running Virtualenv as root, escaping the whole environment which was created, and then, installing the package on global site-packages, and not inside the project folder where you have a Virtual Environment, although you have activated the environment.

If you rename the folder of your project (as mentioned in the accepted answer)...

...you'll have to adjust some variables from some files inside the bin directory of your project.

For example:

bin/pip, line 1 (She Bang)

bin/activate, line 42 (VIRTUAL_ENV)

For me commenting out

'grappelli.dashboard',
'grappelli',

in INSTALLED_APPS worked

Instead of dropping the backup table, just rename it...

BEGIN TRANSACTION;
CREATE TABLE t1_backup(a,b);
INSERT INTO t1_backup SELECT a,b FROM t1;
DROP TABLE t1;
ALTER TABLE t1_backup RENAME TO t1;
COMMIT;

Yes, that will work as you expect it to. Unfortunately, I seem to be having trouble to find an explicit statement of this in the MySQL manual.

Foreign keys mean the value must exist in the other table. NULL refers to the absence of value, so when you set a column to NULL, it wouldn't make sense to try to enforce constraints on that.

You can use numpy's slicing, simply start:stop:step.

>>> xs
array([1, 2, 3, 4, 1, 2, 3, 4, 1, 2, 3, 4])
>>> xs[1::4]
array([2, 2, 2])

This creates a view of the the original data, so it's constant time. It'll also reflect changes to the original array and keep the whole original array in memory:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2]         # O(1), constant time
>>> b[:] = 0           # modifying the view changes original array
>>> a                  # original array is modified
array([0, 2, 0, 4, 0])

so if either of the above things are a problem, you can make a copy explicitly:

>>> a
array([1, 2, 3, 4, 5])
>>> b = a[::2].copy()  # explicit copy, O(n)
>>> b[:] = 0           # modifying the copy
>>> a                  # original is intact
array([1, 2, 3, 4, 5])

This isn't constant time, but the result isn't tied to the original array. The copy also contiguous in memory, which can make some operations on it faster.

This site explain step by step that what you need to do Certificates, Identifiers & Profiles and as your question

"Valid Signing identity not found"?

You need the private key that were used to sign the code base with provisioning profile. . If you don't have then you can generate a new signing request on the iOS developer portal.

For Export:

Xcode -> Organizer, select your team. Click Export. Specify a filename and a password, and click Save.`

For Import:

Xcode -> Organizer, select your team. Click Import. Select the file containing your code signing assets. Enter the password for the file, and click Open.

Let's make this clearer. We use include every time we want to express the fact that the existence of one case depends on the existence of another.

EXAMPLES:

A user can do shopping online only after he has logged in his account. In other words, he can't do any shopping until he has logged in his account.

A user can't download from a site before the material had been uploaded. So, I can't download if nothing has been uploaded.

Do you get it?

It's about conditioned consequence. I can't do this if previously I didn't do that.

At least, I think this is the right way we use Include. I tend to think the example with Laptop and warranty from right above is the most convincing!

background-size: contain; 

suits me

Here is an example using HTML:

<input type="button" value="click me" onclick="this.style.color='#000000';
this.style.backgroundColor = '#ffffff'" />

And here is an example using JavaScript:

document.getElementById("button").bgcolor="#Insert Color Here";

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

Just use gnome, just type in the address and away you go!

It sounds like you're asking about a function

string Left(string s, int left)

that will return the leftmost left characters of the string s. In that case you can just use String.Substring. You can write this as an extension method:

public static class StringExtensions
{
    public static string Left(this string value, int maxLength)
    {
        if (string.IsNullOrEmpty(value)) return value;
        maxLength = Math.Abs(maxLength);

        return ( value.Length <= maxLength 
               ? value 
               : value.Substring(0, maxLength)
               );
    }
}

and use it like so:

string left = s.Left(number);

For your specific example:

string s = fac.GetCachedValue("Auto Print Clinical Warnings").ToLower() + " ";
string left = s.Substring(0, 1);

try Select * from openquery("aa-db-dev01",'Select * from users') ,the database connection should be defined in he linked server configuration

The ? : operator in Java

In Java you might write:

if (a > b) {
  max = a;
}
else {
  max = b;
}

Setting a single variable to one of two states based on a single condition is such a common use of if-else that a shortcut has been devised for it, the conditional operator, ?:. Using the conditional operator you can rewrite the above example in a single line like this:

max = (a > b) ? a : b;

(a > b) ? a : b; is an expression which returns one of two values, a or b. The condition, (a > b), is tested. If it is true the first value, a, is returned. If it is false, the second value, b, is returned. Whichever value is returned is dependent on the conditional test, a > b. The condition can be any expression which returns a boolean value.

When I open Python (command line) the first thing it tells me is the version.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

I solved this problem for myself using grunt. I have the grunt script below. What the script does is takes the command line parameter of the specific test to run and creates a copy of test.ts and puts this specific test name in there.

To run this, first install grunt-cli using:

npm install -g grunt-cli

Put the below grunt dependencies in your package.json:

"grunt": "^1.0.1",
"grunt-contrib-clean": "^1.0.0",
"grunt-contrib-copy": "^1.0.0",
"grunt-exec": "^2.0.0",
"grunt-string-replace": "^1.3.1"

To run it save the below grunt file as Gruntfile.js in your root folder. Then from command line run it as:

grunt --target=app.component

This will run app.component.spec.ts.

Grunt file is as below:

/*
This gruntfile is used to run a specific test in watch mode. Example: To run app.component.spec.ts , the Command is: 
grunt --target=app.component
Do not specific .spec.ts. If no target is specified it will run all tests.
*/
module.exports = function(grunt) {
var target = grunt.option('target') || '';
  // Project configuration.
  grunt.initConfig({
    pkg: grunt.file.readJSON('package.json'),
    clean: ['temp.conf.js','src/temp-test.ts'],
    copy: {
      main: {
        files: [
             {expand: false, cwd: '.', src: ['karma.conf.js'], dest: 'temp.conf.js'},
             {expand: false, cwd: '.', src: ['src/test.ts'], dest: 'src/temp-test.ts'}
             ],
      }
    },
    'string-replace': {
          dist: {
            files: {
              'temp.conf.js': 'temp.conf.js',
              'src/temp-test.ts': 'src/temp-test.ts'
            },
            options: {
              replacements: [{
                pattern: /test.ts/ig,
                replacement: 'temp-test.ts'
              },
              {
                pattern: /const context =.*/ig,
                replacement: 'const context = require.context(\'./\', true, /'+target+'\\\.spec\\\.ts$/);'
              }]
            }
        }
    },
    'exec': {
        sleep: {
          //The sleep command is needed here, else webpack compile fails since it seems like the files in the previous step were touched too recently
          command: 'ping 127.0.0.1 -n 4 > nul',
          stdout: true,
          stderr: true
        },
        ng_test: {
          command: 'ng test --config=temp.conf.js',
          stdout: true,
          stderr: true
        }
    }
  });

  // Load the plugin that provides the "uglify" task.
    grunt.loadNpmTasks('grunt-contrib-clean');
    grunt.loadNpmTasks('grunt-contrib-copy');
    grunt.loadNpmTasks('grunt-string-replace');
    grunt.loadNpmTasks('grunt-exec');
  // Default task(s).
  grunt.registerTask('default', ['clean','copy','string-replace','exec']);

};

this is an out of topic answer, but, for those who are interested, it maybe valuable.

As in @John Kugelman's answer, % is related to job specification. how to efficiently find that? use less's &pattern command, seems man use less pager (not that sure), in man bash type &% then type Enter will only show lines that containing '%', to reshow all, type &. then Enter.

I had the same error problem using Code Blocks rev 13.12. I may be wrong here since I am less than a beginner :)

My problem was that I accidentally capitalized "M" in Main() instead of ALL lowercase = main() - once corrected, it worked!!!

I noticed that you have "int main()" instead of "main()". Is this the problem, or is it supposed to be that way?

Hope I could help...

Please make sure you have downloaded the sqldump fully, this problem is very common when we try to import half/incomplete downloaded sqldump. Please check size of your sqldump file.

toString is a method, so you should add parenthesis () to make the function call.

> a = [1,2,3]
[ 1, 2, 3 ]
> a.toString()
'1,2,3'

Besides, if you want to use strings as keys, then you should consider using a Object instead of Array, and use JSON.stringify to return a string.

> var aa = {}
> aa['a'] = 'aaa'
> JSON.stringify(aa)
'{"a":"aaa","b":"bbb"}'

Your else statement should look like this (note the ^):

{{^avatar}}
 ...
{{/avatar}}

In mustache this is called 'Inverted sections'.

How to easily throttle to a specific FPS:

// timestamps are ms passed since document creation.
// lastTimestamp can be initialized to 0, if main loop is executed immediately
var lastTimestamp = 0,
    maxFPS = 30,
    timestep = 1000 / maxFPS; // ms for each frame

function main(timestamp) {
    window.requestAnimationFrame(main);

    // skip if timestep ms hasn't passed since last frame
    if (timestamp - lastTimestamp < timestep) return;

    lastTimestamp = timestamp;

    // draw frame here
}

window.requestAnimationFrame(main);

Which would you rather write and maintain?

ASP.NET MVC

public class TweetsController : Controller {
  // GET: /Tweets/
  [HttpGet]
  public ActionResult Index() {
    return Json(Twitter.GetTweets(), JsonRequestBehavior.AllowGet);
  }
}

ASP.NET Web API

public class TweetsController : ApiController {
  // GET: /Api/Tweets/
  public List<Tweet> Get() {
    return Twitter.GetTweets();
  }
}

First, open Device Manager by searching for it in the Windows search bar.

Then, click ports and right click the port the Arduino is connected to. Then, go to Port settings → Advanced. Next, select any port that is not in use and is not the port the Arduino is currently connected to. Then click OK and unplug + replug your Arduino. This works most of the time with any Arduino board.

A good way to force your CSS to reload is to:

<link href='styles.css?version=1' rel='stylesheet'></link>

And then just increment the version number as you change your CSS. The browser will then obey. I believe StackOverflow uses this technique.

There is another way also. Try below code

$(document).ready(function(){

      $("input[name='gender']").on("click", function() {
            alert($(this).val());
        });
});

I'm sorry but i can't comment your answers already due my reputation!...so, if you wanna modify the structure of your object, you must do like Thane Plummer says, but a little trick if you do not care where to put the item: it will be inserted on first position if you don't specify the number for the insertion.

This is wonderful if you want to pass a Json object for instance to a mongoDB function call and insert a new key inside the conditions you receive. In this case I gonna insert a item myUid with some info from a variable inside my code:

// From backend or anywhere_x000D_
let myUid = { _id: 'userid128344'};_x000D_
// .._x000D_
// .._x000D_
_x000D_
  let myrequest = { _id: '5d8c94a9f629620ea54ccaea'};_x000D_
  const answer = findWithUid( myrequest).exec();_x000D_
_x000D_
// .._x000D_
// .._x000D_
_x000D_
function findWithUid( conditions) {_x000D_
  const cond_uid = Object.assign({uid: myUid}, conditions);_x000D_
  // the object cond_uid now is:_x000D_
  // {uid: 'userid128344', _id: '5d8c94a9f629620ea54ccaea'}_x000D_
  // so you can pass the new object Json completly with the new key_x000D_
  return myModel.find(cond_uid).exec();_x000D_
}

For C++ (since C++11) adding the test class as a friend works perfectly and does not break production encapsulation.

Let's suppose that we have some class Foo with some private functions which really require testing, and some class FooTest that should have access to Foo's private members. Then we should write the following:

// prod.h: some production code header

// forward declaration is enough
// we should not include testing headers into production code
class FooTest;

class Foo
{
  // that does not affect Foo's functionality
  // but now we have access to Foo's members from FooTest
  friend FooTest;
public:
  Foo();
private:
  bool veryComplicatedPrivateFuncThatReallyRequiresTesting();
}

// test.cpp: some test
#include <prod.h>

class FooTest
{
public:
  void complicatedFisture() {
    Foo foo;
    ASSERT_TRUE(foo.veryComplicatedPrivateFuncThatReallyRequiresTesting());
  }
}

int main(int /*argc*/, char* argv[])
{
  FooTest test;
  test.complicatedFixture();  // and it really works!
}

If you're using this style instead:

@Rule
public MockitoRule rule = MockitoJUnit.rule().strictness(Strictness.STRICT_STUBS);

replace it with:

@Rule
public MockitoRule rule = MockitoJUnit.rule().silent();

You can just use Lombok with access level PRIVATE in @NoArgsConstructor annotation to avoid unnecessary initialization.

@NoArgsConstructor(access = AccessLevel.PRIVATE)

public class FilePathHelper {

// your code

}

Try this:

created_at.strftime('%FT%T')

It's a time formatting function which provides you a way to present the string representation of the date. (http://ruby-doc.org/core-2.2.1/Time.html#method-i-strftime).

I am learning Spring Data JPA. It might help you:

public bool IsNumeric(string value)
{
    return value.All(char.IsNumber);
}

Replace the checkDataBase() code with the code below:

File dbFile = myContext.getDatabasePath(DB_NAME);
return dbFile.exists();

There are several issues with pretty much all the answers here:

1] Hard-coded sql. Will brackets work on all database engines?
2] Entity framework Remove and RemoveRange calls. This loads all entities into memory affected by the operation. Yikes.
3] Truncate table. Breaks with foreign key references and may not work accross all database engines.

Use https://entityframework-plus.net/, they handle the cross database platform stuff, translate the delete into the correct sql statement and don't load entities into memory, and the library is free and open source.

Disclaimer: I am not affiliated with the nuget package. They do offer a paid version that does even more stuff.

In Swift:

For example, name of your custom class is InfoView

At first, you create files InfoView.xib and InfoView.swiftlike this:

import Foundation
import UIKit

class InfoView: UIView {
    class func instanceFromNib() -> UIView {
    return UINib(nibName: "InfoView", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as! UIView
}

Then set File's Owner to UIViewController like this:

Rename your View to InfoView:

Right-click to File's Owner and connect your view field with your InfoView:

Make sure that class name is InfoView:

And after this you can add the action to button in your custom class without any problem:

And usage of this custom class in your MainViewController:

func someMethod() {
    var v = InfoView.instanceFromNib()
    v.frame = self.view.bounds
    self.view.addSubview(v)
}

In UBUNTU use:

$ export NODE_ENV=test

Like it's written up there, you forget to type #include <sstream>

#include <sstream>
using namespace std;

QString Stats_Manager::convertInt(int num)
{
   stringstream ss;
   ss << num;
   return ss.str();
}

You can also use some other ways to convert int to string, like

char numstr[21]; // enough to hold all numbers up to 64-bits
sprintf(numstr, "%d", age);
result = name + numstr;

check this!

Not for entire application or particular class.

CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture at all.

Sample code to change cultures for current thread:

CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;

For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:

(3.3).ToString(new CultureInfo("fr-FR"))

As @hanleyhansen noted in a comment, as of version 0.18.1, the display.height option is deprecated, and says "use display.max_rows instead". So you just have to configure it like this:

pd.set_option('display.max_rows', 500)

See the Release Notes — pandas 0.18.1 documentation:

Deprecated display.height, display.width is now only a formatting option does not control triggering of summary, similar to < 0.11.0.

read.table wants to return a data.frame, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE ) to fill in the blanks.

e.g.

read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
#        V1       V2       V3
#1 Element1 Element2         
#2 Element5 Element6 Element7

A note on whether or not to set header = FALSE... read.table tries to automatically determine if you have a header row thus:

header is set to TRUE if and only if the first row contains one fewer field than the number of columns

When wrapping a pointer in a unique_ptr you cannot have multiple copies of unique_ptr. The shared_ptr holds a reference counter which count the number of copies of the stored pointer. Each time a shared_ptr is copied, this counter is incremented. Each time a shared_ptr is destructed, this counter is decremented. When this counter reaches 0, then the stored object is destroyed.

Should also be able to do this:

total += eval(myInt1) + eval(myInt2) + eval(myInt3);

This helped me in a different, but similar, situation.

You will need to create a virtual device that runs on ARM. Virtual devices running on X86 require an Intel processor. AMD support as specified by Android is only available for Linux systems. If you want a better experience when creating your Virtual Device, use "Store a snapshot for faster startup" instead of the default "Use Host GPU".

git config user.email "insert github email here"
git config user.name "insert github real name here"

This worked great for me.

There is a workaround using Web Server for Chrome.
Here are the steps:

1. Add the Extension to chrome.
2. Choose the folder (C:\images) and launch the server on your desired port.

Now easily access your local file:

function run(){
   // 8887 is the port number you have launched your serve
   var URL = "http://127.0.0.1:8887/002.jpg";

   window.open(URL, null);

}
run();

PS: You might need to select the CORS Header option from advanced setting incase you face any cross origin access error.

I'm new to R as well and faced the exact same problem. But then I looked at my data and noticed that it is being caused due to the fact that my csv file was using a comma separator (,) in all numeric columns (Ex: 1,233,444.56 instead of 1233444.56).

I removed the comma separator in my csv file and then reloaded into R. My data frame now recognises all columns as numbers.

I'm sure there's a way to handle this within the read.csv function itself.

In my case the problem was happening because the class I created had a namespace that interfered with existing classes. The new class A had namespace zz.yy.xx (by mistake). References to objects in another namespace yy.xx were not compiling in class A or other classes whose namespace was zz.

I changed the namespace of class A to yy.xx , which it should have been, and it started working.

Seems to be identical just in case that SQL server will not try to read data which is not required for the query, the optimizer is clever enough

It can have sense when join on complex query (i.e which have joings, groupings etc itself) then, yes, it is better to specify required fields.

But there is one more point. If the query is simple there is no difference but EVERY extra action even which is supposed to improve performance makes optimizer works harder and optimizer can fail to get the best plan in time and will run not optimal query. So extras select can be a such action which can even decrease performance

Add the log4j.properties file to the runtime class path of the project. Some people add this to the root of the source tree (so that it gets copied to the root of the compiled classes).

Edit: If your project is a maven project, you can put the log4j.properties in the src/main/resources folder (and the src/test/resources for your unit tests).

If you have multiple environments (for example development and production), want different logging for each environment, and want to deploy the same jar (or war, or ear) file to each environment (as in one build for all environments) then store the log4j.properties file outside of the jar file and put it in the class path for each environment (configurable by environment). Historically, I would include some known directory in each environment in the classpath and deploy environment specific stuff there. For example, ~tomcat_user/localclasspath where ~tomcat_user is the home directory of the user that will be running the tomcat instance to which my war file will be deployed.

This is hardly a full answer, but webRTC may be what you're looking for. Here's some quick examples of webRTC in action: http://www.webrtc.org/reference-apps

If you want Android specific code, it exists! http://www.webrtc.org/native-code/android

For anyone who came here looking for how to get the true accordion effect and only allow one row to be expanded at a time, you can add an event handler for show.bs.collapse like so:

$('.collapse').on('show.bs.collapse', function () {
    $('.collapse.in').collapse('hide');
});

I modified this example to do so here: http://jsfiddle.net/QLfMU/116/

This has been in the product for years - although it wasn't in the product in 2011.

But, simply click on the Model page.

Make sure you are on at least version 4.0 (released in 2013) to access this feature.

I think you should be using below Component Lifecycle as if you have an input property which on update needs to trigger your component update then this is the best place to do it as its will be called before render you even can do update component state to be reflected on the view.

componentWillReceiveProps: function(nextProps) {
  this.setState({
    likesIncreasing: nextProps.likeCount > this.props.likeCount
  });
}

Substrings with ${variablename:0:5} are a bash feature, not available in basic shells. Are you sure you're running this under bash? Check the shebang line (at the beginning of the script), and make sure it's #!/bin/bash, not #!/bin/sh. And make sure you don't run it with the sh command (i.e. sh scriptname), since that overrides the shebang.

You could do this:

var timer = NSTimer.scheduledTimerWithTimeInterval(0.1, target: self, selector: Selector("someSelector"), userInfo: nil, repeats: false)

func someSelector() {
    // Something after a delay
}

SWIFT 3

let timer = Timer.scheduledTimer(timeInterval: 0.1, target: self, selector: #selector(someSelector), userInfo: nil, repeats: false)

func someSelector() {
    // Something after a delay
}

pluck(column_name)

This method is designed to perform select by a single column as direct SQL query Returns Array with values of the specified column name The values has same data type as column.

Examples:

Person.pluck(:id) # SELECT people.id FROM people
Person.uniq.pluck(:role) # SELECT DISTINCT role FROM people
Person.where(:confirmed => true).limit(5).pluck(:id)

see http://api.rubyonrails.org/classes/ActiveRecord/Calculations.html#method-i-pluck

Its introduced rails 3.2 onwards and accepts only single column. In rails 4, it accepts multiple columns

You are wrong in the way you display the data I guess, because for me:

    String dateString = "03/26/2012 11:49:00 AM";
    SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy hh:mm:ss aa");
    Date convertedDate = new Date();
    try {
        convertedDate = dateFormat.parse(dateString);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
    System.out.println(convertedDate);

Prints:

Mon Mar 26 11:49:00 EEST 2012

I saw in at least one other place that people don't realize Date-Time takes in times as well, so I figured I'd share it here since it's really short to do so:

Get-Date # Following the OP's example, let's say it's Friday, March 12, 2010 9:00:00 AM
(Get-Date '22:00').AddDays(-1) # Thursday, March 11, 2010 10:00:00 PM

It's also the shortest way to strip time information and still use other parameters of Get-Date. For instance you can get seconds since 1970 this way (Unix timestamp):

Get-Date '0:00' -u '%s' # 1268352000

Or you can get an ISO 8601 timestamp:

Get-Date '0:00' -f 's' # 2010-03-12T00:00:00

Then again if you reverse the operands, it gives you a little more freedom with formatting with any date object:

'The sortable timestamp: {0:s}Z{1}Vs measly human format: {0:D}' -f (Get-Date '0:00'), "`r`n"
# The sortable timestamp: 2010-03-12T00:00:00Z
# Vs measly human format: Friday, March 12, 2010

However if you wanted to both format a Unix timestamp (via -u aka -UFormat), you'll need to do it separately. Here's an example of that:

'ISO 8601: {0:s}Z{1}Unix: {2}' -f (Get-Date '0:00'), "`r`n", (Get-Date '0:00' -u '%s')
# ISO 8601: 2010-03-12T00:00:00Z
# Unix: 1268352000

Hope this helps!

res is an HttpResponse object which extends from OutgoingMessage. res.send calls res.end which is implemented by OutgoingMessage to send HTTP response and close connection. We see code here

You can use the dir step, example:

dir("folder") {
    sh "pwd"
}

The folder can be relative or absolute path.

Impossible. A file descriptor may have multiple names in the filesystem, or it may have no name at all.

Edit: Assuming you are talking about a plain old POSIX system, without any OS-specific APIs, since you didn't specify an OS.

This works better when the id = container (which is the outer div) and id = contained (which is the inner div). The problem with the highly recommended solution is that it results in some cases into an horizontal scrolling bar when the browser is trying to cater for the left: -50% attribute. There is a good reference for this solution

        #container {
            text-align: center;
        }
        #contained {
            text-align: left;
            display: inline-block;
        }

I had the same problem and it was because the ~/.bash_profile had invalid fi statements.

The fix:

1. Execute command sudo nano ~/.bash_profile
2. Removed closing fi statements (the ones missing an opening if)
3. Save .bash_profile changes
4. Execute command source ~/.bash_profile

First, what you need to understand the relationships between components. Then you can choose the right method of communication. I will try to explain all the methods that I know and use in my practice for communication between components.

What kinds of relationships between components can there be?

1. Parent > Child

Sharing Data via Input

This is probably the most common method of sharing data. It works by using the @Input() decorator to allow data to be passed via the template.

parent.component.ts

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

@Component({
  selector: 'parent-component',
  template: `
    <child-component [childProperty]="parentProperty"></child-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent{
  parentProperty = "I come from parent"
  constructor() { }
}

child.component.ts

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

@Component({
  selector: 'child-component',
  template: `
      Hi {{ childProperty }}
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  @Input() childProperty: string;

  constructor() { }

}

This is a very simple method. It is easy to use. We can also catch changes to the data in the child component using ngOnChanges.

But do not forget that if we use an object as data and change the parameters of this object, the reference to it will not change. Therefore, if we want to receive a modified object in a child component, it must be immutable.

2. Child > Parent

Sharing Data via ViewChild

ViewChild allows one component to be injected into another, giving the parent access to its attributes and functions. One caveat, however, is that child won’t be available until after the view has been initialized. This means we need to implement the AfterViewInit lifecycle hook to receive the data from the child.

parent.component.ts

import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { ChildComponent } from "../child/child.component";

@Component({
  selector: 'parent-component',
  template: `
    Message: {{ message }}
    <child-compnent></child-compnent>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent implements AfterViewInit {

  @ViewChild(ChildComponent) child;

  constructor() { }

  message:string;

  ngAfterViewInit() {
    this.message = this.child.message
  }
}

child.component.ts

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

@Component({
  selector: 'child-component',
  template: `
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  message = 'Hello!';

  constructor() { }

}

Sharing Data via Output() and EventEmitter

Another way to share data is to emit data from the child, which can be listed by the parent. This approach is ideal when you want to share data changes that occur on things like button clicks, form entries, and other user events.

parent.component.ts

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

@Component({
  selector: 'parent-component',
  template: `
    Message: {{message}}
    <child-component (messageEvent)="receiveMessage($event)"></child-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent {

  constructor() { }

  message:string;

  receiveMessage($event) {
    this.message = $event
  }
}

child.component.ts

import { Component, Output, EventEmitter } from '@angular/core';

@Component({
  selector: 'child-component',
  template: `
      <button (click)="sendMessage()">Send Message</button>
  `,
  styleUrls: ['./child.component.css']
})
export class ChildComponent {

  message: string = "Hello!"

  @Output() messageEvent = new EventEmitter<string>();

  constructor() { }

  sendMessage() {
    this.messageEvent.emit(this.message)
  }
}

3. Siblings

Child > Parent > Child

I try to explain other ways to communicate between siblings below. But you could already understand one of the ways of understanding the above methods.

parent.component.ts

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

@Component({
  selector: 'parent-component',
  template: `
    Message: {{message}}
    <child-one-component (messageEvent)="receiveMessage($event)"></child1-component>
    <child-two-component [childMessage]="message"></child2-component>
  `,
  styleUrls: ['./parent.component.css']
})
export class ParentComponent {

  constructor() { }

  message: string;

  receiveMessage($event) {
    this.message = $event
  }
}

child-one.component.ts

import { Component, Output, EventEmitter } from '@angular/core';

@Component({
  selector: 'child-one-component',
  template: `
      <button (click)="sendMessage()">Send Message</button>
  `,
  styleUrls: ['./child-one.component.css']
})
export class ChildOneComponent {

  message: string = "Hello!"

  @Output() messageEvent = new EventEmitter<string>();

  constructor() { }

  sendMessage() {
    this.messageEvent.emit(this.message)
  }
}

child-two.component.ts

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

@Component({
  selector: 'child-two-component',
  template: `
       {{ message }}
  `,
  styleUrls: ['./child-two.component.css']
})
export class ChildTwoComponent {

  @Input() childMessage: string;

  constructor() { }

}

4. Unrelated Components

All the methods that I have described below can be used for all the above options for the relationship between the components. But each has its own advantages and disadvantages.

Sharing Data with a Service

When passing data between components that lack a direct connection, such as siblings, grandchildren, etc, you should be using a shared service. When you have data that should always be in sync, I find the RxJS BehaviorSubject very useful in this situation.

data.service.ts

import { Injectable } from '@angular/core';
import { BehaviorSubject } from 'rxjs';

@Injectable()
export class DataService {

  private messageSource = new BehaviorSubject('default message');
  currentMessage = this.messageSource.asObservable();

  constructor() { }

  changeMessage(message: string) {
    this.messageSource.next(message)
  }

}

first.component.ts

import { Component, OnInit } from '@angular/core';
import { DataService } from "../data.service";

@Component({
  selector: 'first-componennt',
  template: `
    {{message}}
  `,
  styleUrls: ['./first.component.css']
})
export class FirstComponent implements OnInit {

  message:string;

  constructor(private data: DataService) {
      // The approach in Angular 6 is to declare in constructor
      this.data.currentMessage.subscribe(message => this.message = message);
  }

  ngOnInit() {
    this.data.currentMessage.subscribe(message => this.message = message)
  }

}

second.component.ts

import { Component, OnInit } from '@angular/core';
import { DataService } from "../data.service";

@Component({
  selector: 'second-component',
  template: `
    {{message}}
    <button (click)="newMessage()">New Message</button>
  `,
  styleUrls: ['./second.component.css']
})
export class SecondComponent implements OnInit {

  message:string;

  constructor(private data: DataService) { }

  ngOnInit() {
    this.data.currentMessage.subscribe(message => this.message = message)
  }

  newMessage() {
    this.data.changeMessage("Hello from Second Component")
  }

}

Sharing Data with a Route

Sometimes you need not only pass simple data between component but save some state of the page. For example, we want to save some filter in the online market and then copy this link and send to a friend. And we expect it to open the page in the same state as us. The first, and probably the quickest, way to do this would be to use query parameters.

Query parameters look more along the lines of /people?id= where id can equal anything and you can have as many parameters as you want. The query parameters would be separated by the ampersand character.

When working with query parameters, you don’t need to define them in your routes file, and they can be named parameters. For example, take the following code:

page1.component.ts

import {Component} from "@angular/core";
import {Router, NavigationExtras} from "@angular/router";

@Component({
    selector: "page1",
  template: `
    <button (click)="onTap()">Navigate to page2</button>
  `,
})
export class Page1Component {

    public constructor(private router: Router) { }

    public onTap() {
        let navigationExtras: NavigationExtras = {
            queryParams: {
                "firstname": "Nic",
                "lastname": "Raboy"
            }
        };
        this.router.navigate(["page2"], navigationExtras);
    }

}

In the receiving page, you would receive these query parameters like the following:

page2.component.ts

import {Component} from "@angular/core";
import {ActivatedRoute} from "@angular/router";

@Component({
    selector: "page2",
    template: `
         <span>{{firstname}}</span>
         <span>{{lastname}}</span>
      `,
})
export class Page2Component {

    firstname: string;
    lastname: string;

    public constructor(private route: ActivatedRoute) {
        this.route.queryParams.subscribe(params => {
            this.firstname = params["firstname"];
            this.lastname = params["lastname"];
        });
    }

}

NgRx

The last way, which is more complicated but more powerful, is to use NgRx. This library is not for data sharing; it is a powerful state management library. I can't in a short example explain how to use it, but you can go to the official site and read the documentation about it.

To me, NgRx Store solves multiple issues. For example, when you have to deal with observables and when responsibility for some observable data is shared between different components, the store actions and reducer ensure that data modifications will always be performed "the right way".

It also provides a reliable solution for HTTP requests caching. You will be able to store the requests and their responses so that you can verify that the request you're making does not have a stored response yet.

You can read about NgRx and understand whether you need it in your app or not:

• Angular Service Layers: Redux, RxJs and Ngrx Store - When to Use a Store And Why?
• Ngrx Store - An Architecture Guide

Finally, I want to say that before choosing some of the methods for sharing data you need to understand how this data will be used in the future. I mean maybe just now you can use just an @Input decorator for sharing a username and surname. Then you will add a new component or new module (for example, an admin panel) which needs more information about the user. This means that may be a better way to use a service for user data or some other way to share data. You need to think about it more before you start implementing data sharing.

I am using this code for my project

$(window).scroll ( function() {
    if ($(document).scrollTop() > 50) {
        document.getElementById('your-div').style.height = '100px'; //For eg
    } else {
        document.getElementById('your-div').style.height = '150px';
    }    
}
);

Probably this will help

In C++20 you'll be able to do:

auto result = std::format("{}{}", name, age);

In the meantime you can use the {fmt} library, std::format is based on:

auto result = fmt::format("{}{}", name, age);

Disclaimer: I'm the author of the {fmt} library and C++20 std::format.

I would just like to add that in my case rubygems wasn't installed.

Running sudo apt-get install rubygems solved the issue!

That's because abc is undefined at the moment of the template rendering. You can use safe navigation operator (?) to "protect" template until HTTP call is completed:

{{abc?.xyz?.name}}

You can read more about safe navigation operator here.

Update:

Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf directive to overcome this problem:

<div *ngIf="arr && arr.length > 0">
    {{arr[0].name}}
</div>

Read more about NgIf directive here.

So I'm myself new to React and I found a way to do it.

This solution does not require any extra packages.

Step 1 ReactDocs

In the above docs they mention export in Shell and other options, the one I'll attempt to explain is using .env file

1.1 create Root/.env

#.env file
REACT_APP_SECRET_NAME=secretvaluehere123

Important notes it MUST start with REACT_APP_

1.2 Access ENV variable

#App.js file or the file you need to access ENV
<p>print env secret to HTML</p>
<pre>{process.env.REACT_APP_SECRET_NAME}</pre>

handleFetchData() { // access in API call
  fetch(`https://awesome.api.io?api-key=${process.env.REACT_APP_SECRET_NAME}`)
    .then((res) => res.json())
    .then((data) => console.log(data))
}

1.3 Build Env Issue

So after I did step 1.1|2 it was not working, then I found the above issue/solution. React read/creates env when is built so you need to npm run start every time you modify the .env file so the variables get updated.

Let's say we have an external table called employee

hive> SHOW CREATE TABLE employee;
OK
CREATE EXTERNAL TABLE employee(
  id string,
  fname string,
  lname string, 
  salary double)

1. To create a person table like employee

   CREATE TABLE person LIKE employee;

2. To create a person external table like employee

   CREATE TABLE person LIKE employee LOCATION 'maprfs:/user/hadoop/data/person';

3. then use DESC person; to see the newly created table schema.

You can use this for 24 hour to 12 hour:

echo date("h:i", strtotime($time));

And for vice versa:

echo date("H:i", strtotime($time));

Here's a python 3 script that returns a tuple containing an image height and width for .png, .gif and .jpeg without using any external libraries (ie what Kurt McKee referenced above). Should be relatively easy to transfer it to Python 2.

import struct
import imghdr

def get_image_size(fname):
    '''Determine the image type of fhandle and return its size.
    from draco'''
    with open(fname, 'rb') as fhandle:
        head = fhandle.read(24)
        if len(head) != 24:
            return
        if imghdr.what(fname) == 'png':
            check = struct.unpack('>i', head[4:8])[0]
            if check != 0x0d0a1a0a:
                return
            width, height = struct.unpack('>ii', head[16:24])
        elif imghdr.what(fname) == 'gif':
            width, height = struct.unpack('<HH', head[6:10])
        elif imghdr.what(fname) == 'jpeg':

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

Read this post as a good resource on this implementation/usage. Dynamically creating keys in JavaScript associative array

THanks!

This works for me:

#doit{
    background-image: url('images/pic.png');
    background-repeat: no-repeat;
    background-position: center;  
}  

You can convert Date to almost any format using the Snippet I have added below.

Code:

dateFormat(new Date(),"dd/mm/yy h:MM TT")
//"20/06/14 6:49 PM"

Other examples

// Can also be used as a standalone function
dateFormat(new Date(), "dddd, mmmm dS, yyyy, h:MM:ss TT");
// Saturday, June 9th, 2007, 5:46:21 PM

dateFormat(new Date(),"dddd d mmmm yyyy")
//Monday 2 June 2014"

Snippet:

Add following code taken from this link into your code.

var dateFormat = function () {
    var token = /d{1,4}|m{1,4}|yy(?:yy)?|([HhMsTt])\1?|[LloSZ]|"[^"]*"|'[^']*'/g,
        timezone = /\b(?:[PMCEA][SDP]T|(?:Pacific|Mountain|Central|Eastern|Atlantic) (?:Standard|Daylight|Prevailing) Time|(?:GMT|UTC)(?:[-+]\d{4})?)\b/g,
        timezoneClip = /[^-+\dA-Z]/g,
        pad = function (val, len) {
            val = String(val);
            len = len || 2;
            while (val.length < len) val = "0" + val;
            return val;
        };

    // Regexes and supporting functions are cached through closure
    return function (date, mask, utc) {
        var dF = dateFormat;

        // You can't provide utc if you skip other args (use the "UTC:" mask prefix)
        if (arguments.length == 1 && Object.prototype.toString.call(date) == "[object String]" && !/\d/.test(date)) {
            mask = date;
            date = undefined;
        }

        // Passing date through Date applies Date.parse, if necessary
        date = date ? new Date(date) : new Date;
        if (isNaN(date)) throw SyntaxError("invalid date");

        mask = String(dF.masks[mask] || mask || dF.masks["default"]);

        // Allow setting the utc argument via the mask
        if (mask.slice(0, 4) == "UTC:") {
            mask = mask.slice(4);
            utc = true;
        }

        var _ = utc ? "getUTC" : "get",
            d = date[_ + "Date"](),
            D = date[_ + "Day"](),
            m = date[_ + "Month"](),
            y = date[_ + "FullYear"](),
            H = date[_ + "Hours"](),
            M = date[_ + "Minutes"](),
            s = date[_ + "Seconds"](),
            L = date[_ + "Milliseconds"](),
            o = utc ? 0 : date.getTimezoneOffset(),
            flags = {
                d:    d,
                dd:   pad(d),

        return mask.replace(token, function ($0) {
            return $0 in flags ? flags[$0] : $0.slice(1, $0.length - 1);
        });
    };
}();

// Some common format strings

    isoDateTime:    "yyyy-mm-dd'T'HH:MM:ss",
    isoUtcDateTime: "UTC:yyyy-mm-dd'T'HH:MM:ss'Z'"
};

// Internationalization strings
dateFormat.i18n = {
    dayNames: [
        "Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat",

You can implement your OTF font using @font-face like:

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWeb.otf") format("opentype");
}

@font-face {
    font-family: GraublauWeb;
    font-weight: bold;
    src: url("path/GraublauWebBold.otf") format("opentype");
}

// Edit: OTF now works in most browsers, see comments

However if you want to support a wide variety of browsers i would recommend you to switch to WOFF and TTF font types. WOFF type is implemented by every major desktop browser, while the TTF type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.

@font-face {
    font-family: GraublauWeb;
    src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf")  format("truetype");
}

If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:

@font-face {
    font-family: GraublauWeb;
    src: url("webfont.eot"); /* IE9 Compat Modes */
    src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
         url("webfont.woff") format("woff"), /* Modern Browsers */
         url("webfont.ttf")  format("truetype"), /* Safari, Android, iOS */
         url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}

You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:

WOFF Browser Support

TTF Browser Support

One one line (semi-colons necessary):

for i in 0 1 2 3 4 5 6 7 8 9; do for j in 0 1 2 3 4 5 6 7 8 9; do echo "$i$j"; done; done

Formatted for legibility (no semi-colons needed):

for i in 0 1 2 3 4 5 6 7 8 9
do
    for j in 0 1 2 3 4 5 6 7 8 9
    do 
        echo "$i$j"
    done
done

There are different views on how the shell code should be laid out over multiple lines; that's about what I normally use, unless I put the next operation on the same line as the do (saving two lines here).

$(document).ready(function() {
$("#aDateFrom").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var minDate = $('#aDateFrom').datepicker('getDate');
        $("#aDateTo").datepicker("change", { minDate: minDate });
    }
});

$("#aDateTo").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var maxDate = $('#aDateTo').datepicker('getDate');
        $("#aDateFrom").datepicker("change", { maxDate: maxDate });
    }
});
});

i have made a github repository to show what i think is a good (or best practices) startup project structure...

https://github.com/StefanHeimberg/stackoverflow-1134894

some keywords:

• Maven 3
• BOM (DependencyManagement of own dependencies)
• Parent for all Projects (DependencyManagement from external dependencies and PluginManagement for global Project configuration)
• JUnit / Mockito / DBUnit
• Clean War project without WEB-INF/lib because dependencies are in EAR/lib folder.
• Clean Ear project.
• Minimal deployment descriptors for Java EE7
• No Local EJB Interface because @LocalBean is sufficient.
• Minimal maven configuration through maven user properties
• Actual Deployment Descriptors for Servlet 3.1 / EJB 3.2 / JPA 2.1
• usage of macker-maven-plugin to check architecture rules
• Integration Tests enabled, but skipped. (skipITs=false) useful to enable on CI Build Server

my issue was (master|REBASE 1/1)

this command worked for me

 git rebase --skip

• GitHub

  git config --global url.ssh://[email protected]/.insteadOf https://github.com/
  

• BitBucket

  git config --global url.ssh://[email protected]/.insteadOf https://bitbucket.org/
  

That tells git to always use SSH instead of HTTPS when connecting to GitHub/BitBucket, so you'll authenticate by certificate by default, instead of being prompted for a password.

I had the same issue. This is my solution using angular documentation and firebase Token:

getService()  {

const accessToken=this.afAuth.auth.currentUser.getToken().then(res=>{
  const httpOptions = {
    headers: new HttpHeaders({
      'Content-Type':  'application/json',
      'Authorization': res
    })
  };
  return this.http.get('Url',httpOptions)
    .subscribe(res => console.log(res));
}); }}

The keys are accessed using an exclamation point: ${!array[@]}, the values are accessed using ${array[@]}.

You can iterate over the key/value pairs like this:

for i in "${!array[@]}"
do
  echo "key  : $i"
  echo "value: ${array[$i]}"
done

Note the use of quotes around the variable in the for statement (plus the use of @ instead of *). This is necessary in case any keys include spaces.

The confusion in the other answer comes from the fact that your question includes "foo" and "bar" for both the keys and the values.

For shared libraries libNAME.so the -D switch was necessary to see symbols in my Linux

nm -D libNAME.so

and for static library as reported by others

nm -g libNAME.a
