byte * matToBytes(Mat image)
{
   int size = image.total() * image.elemSize();
   byte * bytes = new byte[size];  //delete[] later
   std::memcpy(bytes,image.data,size * sizeof(byte));
}

I do some quick tests and have the following findings:

1) if using SynchronousQueue:

After the threads reach the maximum size, any new work will be rejected with the exception like below.

Exception in thread "main" java.util.concurrent.RejectedExecutionException: Task java.util.concurrent.FutureTask@3fee733d rejected from java.util.concurrent.ThreadPoolExecutor@5acf9800[Running, pool size = 3, active threads = 3, queued tasks = 0, completed tasks = 0]

at java.util.concurrent.ThreadPoolExecutor$AbortPolicy.rejectedExecution(ThreadPoolExecutor.java:2047)

2) if using LinkedBlockingQueue:

The threads never increase from minimum size to maximum size, meaning the thread pool is fixed size as the minimum size.

If you want to ask based on condition:

var ask = true
window.onbeforeunload = function (e) {
    if(!ask) return null
    e = e || window.event;
    //old browsers
    if (e) {e.returnValue = 'Sure?';}
    //safari, chrome(chrome ignores text)
    return 'Sure?';
};

Not sure how useful this will be, but you can also get the context when you initialize the app. This is the soonest you can get the context, even before an @Autowire.

@SpringBootApplication
public class Application extends SpringBootServletInitializer {
    private static ApplicationContext context;

    // I believe this only runs during an embedded Tomcat with `mvn spring-boot:run`. 
    // I don't believe it runs when deploying to Tomcat on AWS.
    public static void main(String[] args) {
        context = SpringApplication.run(Application.class, args);
        DataSource dataSource = context.getBean(javax.sql.DataSource.class);
        Logger.getLogger("Application").info("DATASOURCE = " + dataSource);

As the title suggests that we want to adjust the size of the labels and not the tick marks I figured that I actually might add something to the question, you need to use the mtext() if you want to specify one of the label sizes, or you can just use par(cex.lab=2) as a simple alternative. Here's a more advanced mtext() example:

set.seed(123)
foo <- data.frame(X = rnorm(10), Y = rnorm(10))
plot(Y ~ X, data=foo,
     yaxt="n", ylab="", 
     xlab="Regular boring x", 
     pch=16,
     col="darkblue")
axis(2,cex.axis=1.2)
mtext("Awesome Y variable", side=2, line=2.2, cex=2)

You may need to adjust the line= option to get the optimal positioning of the text but apart from that it's really easy to use.

You want the gcc-specific noinline attribute.

This function attribute prevents a function from being considered for inlining. If the function does not have side-effects, there are optimizations other than inlining that causes function calls to be optimized away, although the function call is live. To keep such calls from being optimized away, put asm ("");

Use it like this:

void __attribute__ ((noinline)) foo() 
{
  ...
}

Execute chmod 777 -R scripts/, it worked fine for me ;)

Use std::string instead of char-arrays

std::string k ="abcde";
std::vector<std::string> v;
v.push_back(k);

I have seen Big Theta, and I'm pretty sure I was taught the difference in school. I had to look it up though. This is what Wikipedia says:

Big O is the most commonly used asymptotic notation for comparing functions, although in many cases Big O may be replaced with Big Theta T for asymptotically tighter bounds.

Source: Big O Notation#Related asymptotic notation

I don't know why people use Big-O when talking formally. Maybe it's because most people are more familiar with Big-O than Big-Theta? I had forgotten that Big-Theta even existed until you reminded me. Although now that my memory is refreshed, I may end up using it in conversation. :)

put it your input field

ref={(el) => this.myInput = el}

Some time we need to set PATH variable for WINDOWS

%USERPROFILE%\AppData\Roaming\npm

After that test with where grunt

Note: Do not forget to close the command prompt window and reopen it.

Alternatively you could use:

if ($('#navigation a').is(".active")) {
    $(this).parent().addClass("active");
}

myConn.Execute "INSERT INTO DayTr (dtID, DTSuID, DTDaTi, DTGrKg) VALUES (" & Val(txtTrNo) & "," & Val(txtCID) & ", '" & Format(txtTrDate, "yyyy-mm-dd") & "' ," & Val(Format(txtGross, "######0.00")) & ")"

Done in vb with all text type variables.

You can find a comprehensive set of solutions on this in UNIX & Linux's answer to How do you move all files (including hidden) from one directory to another?. It shows solutions in Bash, zsh, ksh93, standard (POSIX) sh, etc.

You can use these two commands together:

mv /path/subfolder/* /path/   # your current approach
mv /path/subfolder/.* /path/  # this one for hidden files

Or all together (thanks pfnuesel):

mv /path/subfolder/{.,}* /path/

Which expands to:

mv /path/subfolder/* /path/subfolder/.* /path/

(example: echo a{.,}b expands to a.b ab)

Note this will show a couple of warnings:

mv: cannot move ‘/path/subfolder/.’ to /path/.’: Device or resource busy
mv: cannot remove /path/subfolder/..’: Is a directory

Just ignore them: this happens because /path/subfolder/{.,}* also expands to /path/subfolder/. and /path/subfolder/.., which are the directory and the parent directory (See What do “.” and “..” mean when in a folder?).

If you want to just copy, you can use a mere:

cp -r /path/subfolder/. /path/
#                     ^
#                     note the dot!

This will copy all files, both normal and hidden ones, since /path/subfolder/. expands to "everything from this directory" (Source: How to copy with cp to include hidden files and hidden directories and their contents?)

Compile configuration was deprecated and should be replaced by implementation or api.

You can read the docs at https://docs.gradle.org/current/userguide/java_library_plugin.html#sec:java_library_separation.

The brief part being-

The key difference between the standard Java plugin and the Java Library plugin is that the latter introduces the concept of an API exposed to consumers. A library is a Java component meant to be consumed by other components. It's a very common use case in multi-project builds, but also as soon as you have external dependencies.

The plugin exposes two configurations that can be used to declare dependencies: api and implementation. The api configuration should be used to declare dependencies which are exported by the library API, whereas the implementation configuration should be used to declare dependencies which are internal to the component.

For further explanation refer to this image.

By using exploits or on badly configured servers it could be possible to download your PHP source. You could however either obfuscate and/or encrypt your code (using Zend Guard, Ioncube or a similar app) if you want to make sure your source will not be readable (to be accurate, obfuscation by itself could be reversed given enough time/resources, but I haven't found an IonCube or Zend Guard decryptor yet...).

Drawable d = getResources().getDrawable(android.R.drawable.ic_dialog_email);
ImageView image = (ImageView)findViewById(R.id.image);
image.setImageDrawable(d);

In KOTLIN:- If you want to save Token into DB or shared preferences then override onNewToken in FirebaseMessagingService

override fun onNewToken(token: String) {
        super.onNewToken(token)
    }

Get token at run-time,use

FirebaseInstanceId.getInstance().instanceId
                        .addOnSuccessListener(this@SplashActivity) { instanceIdResult ->
                            val mToken = instanceIdResult.token
                            println("printing  fcm token: $mToken")
                        }

Sound like you just have an issue with the path. Include the full path, if you use backslashes they need to be escaped: "C:\\folder\\folder\\Desktop\\file.csv" or "C:/folder/folder/Desktop/file.csv".

myfile = read.csv("C:/folder/folder/Desktop/file.csv")  # or read.table()

It may also be wise to avoid spaces and symbols in your file names, though I'm fairly certain spaces are OK.

I added this for pages that were too short.

html:

<section id="secondary-foot"></section>

css:

section#secondary-foot {
    height: 100%;
    background-color: #000000;
    position: fixed;
    width: 100%;
}

You are defining your array as xlValidateList(), so when you try to assign the type, it gets confused as to what you are trying to assign to the type.

Instead, try this:

Dim MyList(5) As String
MyList(0) = 1
MyList(1) = 2
MyList(2) = 3
MyList(3) = 4
MyList(4) = 5
MyList(5) = 6

With Range("A1").Validation
    .Delete
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
         Operator:=xlBetween, Formula1:=Join(MyList, ",")
End With

As mentioned you can use:

overflow: scroll;

If you only want the scroll bar to appear when necessary, you can use the "auto" option:

overflow: auto;

I don't think you should be using the "float" property with "overflow", but I'd have to try out your example first.

Short answer: Yes, you need to rename .cpp files to c, so you can write C: https://msdn.microsoft.com/en-us/library/bb384838.aspx?f=255&MSPPError=-2147217396

From the link above:

By default, the Visual C++ compiler treats all files that end in .c as C source code, and all files that end in .cpp as C++ source code. To force the compiler to treat all files as C regardless of file name extension, use the /Tc compiler option.

That being said, I do not recommend learning C language in Visual Studio, why VS? It does have lots of features you are not going to use while learning C

To detect both positive and negative peaks, PeakDetect is helpful.

from peakdetect import peakdetect

peaks = peakdetect(data, lookahead=20) 
# Lookahead is the distance to look ahead from a peak to determine if it is the actual peak. 
# Change lookahead as necessary 
higherPeaks = np.array(peaks[0])
lowerPeaks = np.array(peaks[1])
plt.plot(data)
plt.plot(higherPeaks[:,0], higherPeaks[:,1], 'ro')
plt.plot(lowerPeaks[:,0], lowerPeaks[:,1], 'ko')

If you just want to create a default POM and enable m2eclipse features: so I'm assuming you do not currently have an alternative automated build setup you're trying to import, and I'm assuming you're talking about the m2eclipse plugin.

The m2eclipse plugin provides a right-click option on a project to add this default pom.xml:

Newer M2E versions

Right click on Project -> submenu Configure -> Convert to Maven Project

Older M2E versions

Right click on Project -> submenu Maven -> Enable Dependency Management.

That'll do the necessary to enable the plugin for that project.

To answer 'is there an automatic importer or wizard?': not that I know of. Using the option above will allow you to enable the m2eclipse plugin for your existing project avoiding the manual copying. You will still need to actually set up the dependencies and other stuff you need to build yourself.

With Yglu Structural Templating, your example can be written:

foo: !()
  !? $.propname: 
     type: number 
     default: !? $.default

bar:
  !apply .foo: 
    propname: "some_prop"
    default: "some default"

Disclaimer: I am the author or Yglu.

For repeating an action in the future, there is the built in setInterval function that you can use instead of setTimeout.
It has a similar signature, so the transition from one to another is simple:

setInterval(function() {
    // do stuff
}, duration);

What about inv?

e.g.: my_inverse_array = inv(my_array)

XSD files are used to validate that XML files conform to a certain format.

In that respect they are similar to DTDs that existed before them.

The main difference between XSD and DTD is that XSD is written in XML and is considered easier to read and understand.

I am introducing Two custom library functions to be used in vba, which will serve the purpose of rounding the double value instead of using WorkSheetFunction.RoundDown and WorkSheetFunction.RoundUp

Function RDown(Amount As Double, digits As Integer) As Double
    RDown = Int((Amount + (1 / (10 ^ (digits + 1)))) * (10 ^ digits)) / (10 ^ digits)
End Function

Function RUp(Amount As Double, digits As Integer) As Double
    RUp = RDown(Amount + (5 / (10 ^ (digits + 1))), digits)
End Function

Thus function Rdown(2878.75 * 31.1,2) will return 899529.12 and function RUp(2878.75 * 31.1,2) will return 899529.13 Whereas The function Rdown(2878.75 * 31.1,-3) will return 89000 and function RUp(2878.75 * 31.1,-3) will return 90000

In python 3, a way of doing this would be

'{:.2f}'.format(number)

An idea could be to just drop and recreate the tables?

EDIT:

@Jonathan Leffler: True

Other Suggestion (or case you dont need to truncate ALL tables):

Why not just create a basic stored procedure to truncate specific tables

CREATE PROCEDURE [dbo].[proc_TruncateTables]
AS
TRUNCATE TABLE Table1
TRUNCATE TABLE Table2
TRUNCATE TABLE Table3
GO

The const keyword used with the function declaration specifies that it is a const member function and it will not be able to change the data members of the object.

Thought I'd simplify the simplest examples copied from above, working for me on Py3.6. Simplest is multiprocessing.Pool:

import multiprocessing
import time

def worker(x):
    time.sleep(1)
    return x

pool = multiprocessing.Pool()
print(pool.map(worker, range(10)))

You can set the number of processes in the pool with, e.g., Pool(processes=5). However it defaults to CPU count, so leave it blank for CPU-bound tasks. (I/O-bound tasks often suit threads anyway, as the threads are mostly waiting so can share a CPU core.) Pool also applies chunking optimization.

(Note that the worker method cannot be nested within a method. I initially defined my worker method inside the method that makes the call to pool.map, to keep it all self-contained, but then the processes couldn't import it, and threw "AttributeError: Can't pickle local object outer_method..inner_method". More here. It can be inside a class.)

(Appreciate the original question specified printing 'represent!' rather than time.sleep(), but without it I thought some code was running concurrently when it wasn't.)

Py3's ProcessPoolExecutor is also two lines (.map returns a generator so you need the list()):

from concurrent.futures import ProcessPoolExecutor
with ProcessPoolExecutor() as executor:
    print(list(executor.map(worker, range(10))))

With plain Processes:

import multiprocessing
import time

def worker(x, queue):
    time.sleep(1)
    queue.put(x)

queue = multiprocessing.SimpleQueue()
tasks = range(10)

for task in tasks:
    multiprocessing.Process(target=worker, args=(task, queue,)).start()

for _ in tasks:
    print(queue.get())

Use SimpleQueue if all you need is put and get. The first loop starts all the processes, before the second makes the blocking queue.get calls. I don't think there's any reason to call p.join() too.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|00D900",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(12, 18)
);

When you use df.apply(), each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label].

So this should work:

df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1)) 

Small performance test comparision for three solutions:

1. $(".link").prop('href',"https://example.com")
2. $(".link").attr('href',"https://example.com")
3. document.querySelector(".link").href="https://example.com";

Here you can perform test by yourself https://jsperf.com/a-href-js-change

We can read href values in following ways

1. let href = $(selector).prop('href');
2. let href = $(selector).attr('href');
3. let href = document.querySelector(".link").href;

Here you can perform test by yourself https://jsperf.com/a-href-js-read

You can add a tree observer to the layout. This should return the correct width and height. onCreate() is called before the layout of the child views are done. So the width and height is not calculated yet. To get the height and width, put this on the onCreate() method:

    final LinearLayout layout = (LinearLayout) findViewById(R.id.YOUR_VIEW_ID);
    ViewTreeObserver vto = layout.getViewTreeObserver(); 
    vto.addOnGlobalLayoutListener (new OnGlobalLayoutListener() { 
        @Override 
        public void onGlobalLayout() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                    layout.getViewTreeObserver()
                            .removeOnGlobalLayoutListener(this);
                } else {
                    layout.getViewTreeObserver()
                            .removeGlobalOnLayoutListener(this);
                }
            int width  = layout.getMeasuredWidth();
            int height = layout.getMeasuredHeight(); 

        } 
    });

They are both rubbish! XCOPY was older and unreliable, so Microsoft replaced it with ROBOCOPY, which is still rubbish.

http://answers.microsoft.com/en-us/windows/forum/windows_8-files/robocopy-appears-to-be-broken-in-windows-8/9a7634c4-3a9d-4f2d-97ae-093002a638a9

Don't worry though, it is a long-standing tradition that was started by the original COPY command, which to this day, still needs the /B switch to get it to actually copy properly!

The major difference between the two is that $_SERVER['SERVER_NAME'] is a server controlled variable, while $_SERVER['HTTP_HOST'] is a user-controlled value.

The rule of thumb is to never trust values from the user, so $_SERVER['SERVER_NAME'] is the better choice.

As Gumbo pointed out, Apache will construct SERVER_NAME from user-supplied values if you don't set UseCanonicalName On.

Edit: Having said all that, if the site is using a name-based virtual host, the HTTP Host header is the only way to reach sites that aren't the default site.

If you're using local workspaces (TFS 2012+) you can now use the .tfignore file to exclude local folders and files from being checked in.

If you add that file to source control you can ensure others on your team share the same exclusion settings.

Full details on MSDN - http://msdn.microsoft.com/en-us/library/ms245454.aspx#tfignore

For the lazy:

You can configure which kinds of files are ignored by placing a text file called .tfignore in the folder where you want rules to apply. The effects of the .tfignore file are recursive. However, you can create .tfignore files in sub-folders to override the effects of a .tfignore file in a parent folder.

The following rules apply to a .tfignore file:

• # begins a comment line
• The * and ? wildcards are supported.
• A filespec is recursive unless prefixed by the \ character.
• ! negates a filespec (files that match the pattern are not ignored)

Example file:

# Ignore .cpp files in the ProjA sub-folder and all its subfolders
ProjA\*.cpp
# 
# Ignore .txt files in this folder 
\*.txt
#
# Ignore .xml files in this folder and all its sub-folders
*.xml
#
# Ignore all files in the Temp sub-folder
\Temp
#
# Do not ignore .dll files in this folder nor in any of its sub-folders
!*.dll

One way is using a template function in your directive:

...
template: function(tElem, tAttrs){
    return '<div ng-include="' + tAttrs.template + '" />';
}
...

This error is quite right and highlights a contextual syntax issue. Can be reproduced by performing any kind "non-assignable" syntax. For instance:

function Syntax($hello) { .... then attempt to call the function as though a property and assign a value.... $this->Syntax('Hello') = 'World';

The above error will be thrown because syntactially the statement is wrong. The right assignment of 'World' cannot be written in the context you have used (i.e. syntactically incorrect for this context). 'Cannot use function return value' or it could read 'Cannot assign the right-hand value to the function because its read-only'

The specific error in the OPs code is as highlighted, using brackets instead of square brackets.

Just use the statement:

break;

You have to construct a new string out of a byte array. The first element in your byteArray should be 0x63. If you want to add any more letters, make the byteArray longer and add them to the next indices.

byte[] byteArray = new byte[1];
byteArray[0] = 0x63;

try {
    System.out.println("string " + new String(byteArray, "US-ASCII"));
} catch (UnsupportedEncodingException e) {
    // TODO: Handle exception.
    e.printStackTrace();
}

Note that specifying the encoding will eventually throw an UnsupportedEncodingException and you must handle that accordingly.

As a slight improvement to this suggestion, you can use the Validation plugin with its number(), digits, and range methods. For example, the following ensures you get a positive integer between 0 and 50:

$("#myform").validate({
  rules: {
    field: {
      required: true,
      number: true,
      digits: true,
      range : [0, 50]
    }
  }
});

Git can search diffs with the -S option (it's called pickaxe in the docs)

git log -S password

This will find any commit that added or removed the string password. Here a few options:

• -p: will show the diffs. If you provide a file (-p file), it will generate a patch for you.
• -G: looks for differences whose added or removed line matches the given regexp, as opposed to -S, which "looks for differences that introduce or remove an instance of string".
• --all: searches over all branches and tags; alternatively, use --branches[=<pattern>] or --tags[=<pattern>]

Yes it is the correct way, but the synchronised block is required if you want all the removals together to be safe - unless the queue is empty no removals allowed. My guess is that you just want safe queue and dequeue operations, so you can remove the synchronised block.

However, there are far advanced concurrent queues in Java such as ConcurrentLinkedQueue

If you use chldNode as XmlElement instead of XmlNode, you can use

var attributeValue = chldNode.GetAttribute("Name");

The return value will just be an empty string, in case the attribute name does not exist.

So your loop could look like this:

XmlDocument document = new XmlDocument();
var nodes = document.SelectNodes("//Node/N0de/node");

foreach (XmlElement node in nodes)
{
    var attributeValue = node.GetAttribute("Name");
}

This will select all nodes <node> surrounded by <Node><N0de></N0de><Node> tags and subsequently loop through them and read the attribute "Name".

In Windows 10 I had to run the batch file as an administrator.

Unlike languages that employ 'true' lexical scoping, Python opts to have specific 'namespaces' for variables, whether it be global, nonlocal, or local. It could be argued that making developers consciously code with such namespaces in mind is more explicit, thus more understandable. I would argue that such complexities make the language more unwieldy, but I guess it's all down to personal preference.

Here are some examples regarding global:-

>>> global_var = 5
>>> def fn():
...     print(global_var)
... 
>>> fn()
5
>>> def fn_2():
...     global_var += 2
...     print(global_var)
... 
>>> fn_2()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 2, in fn_2
UnboundLocalError: local variable 'global_var' referenced before assignment
>>> def fn_3():
...     global global_var
...     global_var += 2
...     print(global_var)
... 
>>> fn_3()
7

The same patterns can be applied to nonlocal variables too, but this keyword is only available to the latter Python versions.

In case you're wondering, nonlocal is used where a variable isn't global, but isn't within the function definition it's being used. For example, a def within a def, which is a common occurrence partially due to a lack of multi-statement lambdas. There's a hack to bypass the lack of this feature in the earlier Pythons though, I vaguely remember it involving the use of a single-element list...

Note that writing to variables is where these keywords are needed. Just reading from them isn't ambiguous, thus not needed. Unless you have inner defs using the same variable names as the outer ones, which just should just be avoided to be honest.

NotFoundMVC - Provides a user-friendly 404 page whenever a controller, action or route is not found in your ASP.NET MVC3 application. A view called NotFound is rendered instead of the default ASP.NET error page.

You can add this plugin via nuget using: Install-Package NotFoundMvc

NotFoundMvc automatically installs itself during web application start-up. It handles all the different ways a 404 HttpException is usually thrown by ASP.NET MVC. This includes a missing controller, action and route.

Step by Step Installation Guide :

1 - Right click on your Project and Select Manage Nuget Packages...

2 - Search for NotFoundMvc and install it.

3 - Once the installation has be completed, two files will be added to your project. As shown in the screenshots below.

4 - Open the newly added NotFound.cshtml present at Views/Shared and modify it at your will. Now run the application and type in an incorrect url, and you will be greeted with a User friendly 404 page.

No more, will users get errors message like Server Error in '/' Application. The resource cannot be found.

Hope this helps :)

P.S : Kudos to Andrew Davey for making such an awesome plugin.

ColinE's answer is simple and elegant. If your lists are larger and provided that the excluded apps list is sorted, BinarySearch<T> may prove faster than Contains.

EXAMPLE:

unfilteredApps.Where(i => excludedAppIds.BinarySearch(i.Id) < 0);

Personally I've always used if (ptr == NULL) because it makes my intent explicit, but at this point it's just a habit.

Using = in place of == will be caught by any competent compiler with the correct warning settings.

The important point is to pick a consistent style for your group and stick to it. No matter which way you go, you'll eventually get used to it, and the loss of friction when working in other people's code will be welcome.

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class RemoveDuplicacy
{
        public static void main(String args[])throws IOException
        {
            BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
            System.out.print("Enter any word : ");
            String s = br.readLine();
            int l = s.length();
            char ch;
            String ans=" ";

            for(int i=0; i<l; i++)
            {
                ch = s.charAt(i);
                if(ch!=' ')
                    ans = ans + ch;
                s = s.replace(ch,' '); //Replacing all occurrence of the current character by a space
            }

           System.out.println("Word after removing duplicate characters : " + ans);
        }

}

According to Scott Myers, Effective C++ (3rd ed.) item 42 (which must, of course, be the ultimate answer) - the difference is "nothing".

Advice is to use "class" if it is expected T will always be a class, with "typename" if other types (int, char* whatever) may be expected. Consider it a usage hint.

In BASH, you can find a user's $HOME directory by prefixing the user's login ID with a tilde character. For example:

$ echo ~bob

This will echo out user bob's $HOME directory.

However, you say you want to be able to execute a script as a particular user. To do that, you need to setup sudo. This command allows you to execute particular commands as either a particular user. For example, to execute foo as user bob:

$ sudo -i -ubob -sfoo

This will start up a new shell, and the -i will simulate a login with the user's default environment and shell (which means the foo command will execute from the bob's$HOME` directory.)

Sudo is a bit complex to setup, and you need to be a superuser just to be able to see the shudders file (usually /etc/sudoers). However, this file usually has several examples you can use.

In this file, you can specify the commands you specify who can run a command, as which user, and whether or not that user has to enter their password before executing that command. This is normally the default (because it proves that this is the user and not someone who came by while the user was getting a Coke.) However, when you run a shell script, you usually want to disable this feature.

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" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

Solution that I used for this problem:

 public static void applyFontForToolbarTitle(Activity a){
        Toolbar toolbar = (Toolbar) a.findViewById(R.id.app_bar);
        for(int i = 0; i < toolbar.getChildCount(); i++){
            View view = toolbar.getChildAt(i);
            if(view instanceof TextView){
                TextView tv = (TextView) view;
                if(tv.getText().equals(a.getTitle())){
                    tv.setTypeface(getRuneTypefaceBold(a));
                    break;
                }
            }
        }
    }

For center gravity I think it would be necessary to change layout params to match_parent horizontally and then:

tv.setGravity(Gravity.CENTER);

You have to add just one line

useLibrary 'org.apache.http.legacy'

into build.gradle(Module: app), for example

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "25.0.0"

    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.avenues.lib.testotpappnew"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:24.2.1'
    testCompile 'junit:junit:4.12'
}

You could also use HttpURLConnection, which allows you to set the request method (to HEAD for example). Here's an example that shows how to send a request, read the response, and disconnect.

it can also happen if you move required files. Simply check Problems View (menu window -> show view -> Problems) as told here

grep

Select-String cmdlet and -match operator work with regexes. Also you can directly make use of .NET's regex support for more advanced functionality.

sort

Sort-Object is more powerful (than I remember *nix's sort). Allowing multi-level sorting on arbitrary expressions. Here PowerShell's maintenance of underlying type helps; e.g. a DateTime property will be sorted as a DateTime without having to ensure formatting into a sortable format.

uniq

Select-Object -Unique

Perl (how close does PowerShell come to Perl capabilities?)

In terms of Perl's breadth of domain specific support libraries: nowhere close (yet).

For general programming, PowerShell is certainly more cohesive and consistent, and easier to extend. The one gap for text munging is something equivalent to Perl's .. operator.

AWK

It has been long enough since using AWK (must be >18 years, since later I just used Perl), so can't really comment.

sed

[See above]

file (the command that gives file information)

PowerShell's strength here isn't so much of what it can do with filesystem objects (and it gets full information here, dir returns FileInfo or FolderInfo objects as appropriate) is that is the whole provider model.

You can treat the registry, certificate store, SQL Server, Internet Explorer's RSS cache, etc. as an object space navigable by the same cmdlets as the filesystem.

PowerShell is definitely the way forward on Windows. Microsoft has made it part of their requirements for future non-home products. Hence rich support in Exchange, support in SQL Server. This is only going to expand.

A recent example of this is the TFS PowerToys. Many TFS client operations are done without having to startup tf.exe each time (which requires a new TFS server connection, etc.) and is notably easier to then further process the data. As well as allowing wide access to the whole TFS client API to a greater detail than exposed in either Team Explorer of TF.exe.

This worked for me using the current working directory in PowerShell. You need to use the FullName property, or it won't work in PowerShell version 5. I needed to change the target .NET framework version in ALL my CSPROJ files.

gci -Recurse -Filter *.csproj |
% { (get-content "$($_.FullName)")
.Replace('<TargetFramework>net47</TargetFramework>', '<TargetFramework>net462</TargetFramework>') |
 Set-Content "$($_.FullName)"}

select * from (
    select FName from MyTbl
)
where rownum <= 1;

Just find your form and clear before it opens!

    $modal = $('#modal');
    $modal.find('form')[0].reset();

New versions of excel have made old answers obsolete. It took a long time to make this, but it does a pretty good job. Note that the maximum image size is limited and the aspect ratio is ever so slightly off, as I was not able to perfectly optimize the reshaping math. Note that I've named one of my worksheets wsTMP, you can replace it with Sheet1 or the like. Takes about 1 second to print the screenshot to target path.

It happened to me too, and After reading all solutions, I've deleted the created drive and started all over.

The first case (the one that didn't worked) was windows 7 64 bit.

After trying the config as Win 7 32 bit that error didn't appeared again.

Hope this helps someone.

Removing =initMap worked for me:

Please read the other answers and comments, there’s a lot more information stated and nuances described (hash functions?) that I did not know when I answered this question.

According to Jenkins' own help (the "?" button) for the schedule task, 5 fields are specified:

This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace: MINUTE HOUR DOM MONTH DOW

I just tried to get a job to launch at 4:42PM (my approximate local time) and it worked with the following, though it took about 30 extra seconds:

42 16 * * *

If you want multiple times, I think the following should work:

0 16,18,20,22 * * *

for 4, 6, 8, and 10 o'clock PM every day.

This should fix a few edge-cases in kobe's answer:

function getQueryParam(url, key) {
  var queryStartPos = url.indexOf('?');
  if (queryStartPos === -1) {
    return;
  }
  var params = url.substring(queryStartPos + 1).split('&');
  for (var i = 0; i < params.length; i++) {
    var pairs = params[i].split('=');
    if (decodeURIComponent(pairs.shift()) == key) {
      return decodeURIComponent(pairs.join('='));
    }
  }
}

getQueryParam('http://example.com/form_image_edit.php?img_id=33', 'img_id');
// outputs "33"

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

In general you can extract a string from object with the class name,

str_class = object.__class__.__name__

and using it for comparison,

if str_class == 'dict':
    # blablabla..
elif str_class == 'customclass':
    # blebleble..

Object.equals() method checks only reference of object not primitive data type or Object value (Wrapper class object of primitive data, simple primitive data type (byte, short, int, long etc.)). So that we must override equals() method when we compare object based on primitive data type.

Sometimes JavaScript is not activated. Try something like:

<!DOCTYPE html>
<html>
  <head>

    <script type="text/javascript"> <!--
      function jActivator() {
        document.getElementById("demo").onclick = function() {myFunction()};
        document.getElementById("demo1").addEventListener("click", myFunction);
        }
      function myFunction( s ) {
        document.getElementById("myresult").innerHTML = s;
        }
    // --> </script>
    <noscript>JavaScript deactivated.</noscript>
    <style type="text/css">
    </style>
  </head>
  <body onload="jActivator()">
    <ul>
      <li id="demo">Click me -&gt; onclick.</li>
      <li id="demo1">Click me -&gt; click event.</li>
      <li onclick="myFunction('YOU CLICKED ME!')">Click me calling function.</li>
    </ul>
    <div id="myresult">&nbsp;</div>
  </body>
</html>

If you use the code inside a page, where no access to is possible, remove and tags and try to use 'onload=()' in a picture inside the image tag '

in Java, this is how you can separate digits from numbers and store them in an Array.

public static void main(String[] args) {
        System.out.println("Digits Array:: "+Arrays.toString(getNumberArr(1100)));
}

private static Integer[] getNumberArr(int number) {
    //will get the total number of digits in the number
    int temp = number;
    int counter = 0;

    while (temp > 0) {
        temp /= 10;
        counter++;
    }
    //reset the temp
    temp = number;

    // make an array
    int modulo;     //modulo is equivalent to single digit of the number.
    Integer[] numberArr = new Integer[counter];
    for (int i = counter - 1; i >= 0; i--) {
        modulo = temp % 10;
        numberArr[i] = modulo;  
        temp /= 10;
    }

    return numberArr;
}

Output:

Digits Array:: [1, 1, 0, 0]

No idea why the cast works, but Foo::MEMBER isn't allocated until the first time Foo is loaded, and since you're never loading it, it's never allocated. If you had a reference to a Foo somewhere, it would probably work.

Parsing command line arguments in a primitive way as explained in the above answers is reasonable as long as the number of parameters that you need to deal with is not too much.

I strongly suggest you to use an industrial strength library for handling the command line arguments.

This will make your code more professional.

Such a library for C++ is available in the following website. I have used this library in many of my projects, hence I can confidently say that this one of the easiest yet useful library for command line argument parsing. Besides, since it is just a template library, it is easier to import into your project. http://tclap.sourceforge.net/

A similar library is available for C as well. http://argtable.sourceforge.net/

If you want to comment in Android Studio simply press:

Ctrl + / on Windows/Linux

Cmd + / on Mac.

This works in XML files such as strings.xml as well as in code files like MainActivity.java.

Note: always try to detect the specific behavior you're trying to fix, instead of targeting it with isSafari?

As a last resort, detect Safari with this regex:

var isSafari = /^((?!chrome|android).)*safari/i.test(navigator.userAgent);

It uses negative look-arounds and it excludes Chrome, Edge, and all Android browsers that include the Safari name in their user agent.

Use String.Trim method.

With all respect the most likely thing is that you are mistaken about why the click is being 'rejected'. Why do you think some program is trying to determine if it's human or not? The Robot class (have used it a lot) should send messages that the operating system has no way to distinguish from a user doing the click.

Open your settings.xml file ~/.m2/settings.xml (create it if it doesn't exist). Add a section with the properties added. Then make sure the activeProfiles includes the new profile.

Pattern! The group names a (sub)pattern for later use in the regex. See the documentation here for details about how such groups are used.

Problem

While the pattern for testing multiple values

>>> 2 in {1, 2, 3}
True
>>> 5 in {1, 2, 3}
False

is very readable and is working in many situation, there is one pitfall:

>>> 0 in {True, False}
True

But we want to have

>>> (0 is True) or (0 is False)
False

Solution

One generalization of the previous expression is based on the answer from ytpillai:

>>> any([0 is True, 0 is False])
False

which can be written as

>>> any(0 is item for item in (True, False))
False

While this expression returns the right result it is not as readable as the first expression :-(

Not plumbing, but I have these in my .gitconfig:

lsum = log -n 1 --pretty=format:'%s'
lmsg = log -n 1 --pretty=format:'%s%n%n%b'

That's "last summary" and "last message". You can provide a commit to get the summary or message of that commit. (I'm using 1.7.0.5 so don't have %B.)

Download Json.NET from here http://james.newtonking.com/projects/json-net.aspx

name deserializedName = JsonConvert.DeserializeObject<name>(jsonData);

Here is my reason:

before:

var path = "D:\xxx\util.s"

which \u is a escape, I figured it out by using Codepen's analyze JS.

after:

var path = "D:\\xxx\\util.s"

and the error fixed

On some platforms and for some types there are specific printf conversion specifiers available, but sometimes one has to resort to casting to larger types.

I've documented this tricky issue here, with example code: http://www.pixelbeat.org/programming/gcc/int_types/ and update it periodically with info on new platforms and types.

To compare two lists with the order preserved use,

assertThat(actualList, contains("item1","item2"));

Assuming property as PropertyInfo type, you can do this in one single line:

property.GetCustomAttributes(typeof(DisplayNameAttribute), true).Cast<DisplayNameAttribute>().Single().DisplayName

If you are looking for a .NET Core compatible way, use

System.AppContext.BaseDirectory

This was introduced in .NET Framework 4.6 and .NET Core 1.0 (and .NET Standard 1.3). See: AppContext.BaseDirectory Property.

According to this page,

This is the prefered replacement for AppDomain.CurrentDomain.BaseDirectory in .NET Core

You need an scp client. Putty is not one. You can use WinSCP or PSCP. Both are free software.

for swift 5, I write a demo to verify it.

extension String {

    /// convert JsonString to Dictionary
    func convertJsonStringToDictionary() -> [String: Any]? {
        if let data = data(using: .utf8) {
            return (try? JSONSerialization.jsonObject(with: data, options: [])) as? [String: Any]
        }

        return nil
    }
}

let str = "{\"name\":\"zgpeace\"}"
let dict = str.convertJsonStringToDictionary()
print("string > \(str)")  
// string > {"name":"zgpeace"}
print("dicionary > \(String(describing: dict))") 
// dicionary > Optional(["name": zgpeace])

well, in some programming languages they are called functions others call it methods, the fact is they are the same thing. It just represents an abstractized form of reffering to a mathematical function:

f -> f(N:N).

meaning its a function with values from natural numbers (just an example). So besides the name Its exactly the same thing, representing a block of code containing instructions in resolving your purpose.

I use ".hpp" for C++ headers and ".h" for C language headers. The ".hpp" reminds me that the file contains statements for the C++ language which are not valid for the C language, such as "class" declarations.

To filter a list of dicts you can use the selectattr filter together with the equalto test:

network.addresses.private_man | selectattr("type", "equalto", "fixed")

The above requires Jinja2 v2.8 or later (regardless of Ansible version).

Ansible also has the tests match and search, which take regular expressions:

match will require a complete match in the string, while search will require a match inside of the string.

network.addresses.private_man | selectattr("type", "match", "^fixed$")

To reduce the list of dicts to a list of strings, so you only get a list of the addr fields, you can use the map filter:

... | map(attribute='addr') | list

Or if you want a comma separated string:

... | map(attribute='addr') | join(',')

Combined, it would look like this.

- debug: msg={{ network.addresses.private_man | selectattr("type", "equalto", "fixed") | map(attribute='addr') | join(',') }}

In my situation, I have many namespaces and after some debug I find another solution just changing the NamespaceFitler class. For my situation (just unmarshall) this work fine.

 import javax.xml.namespace.QName;
 import org.xml.sax.Attributes;
 import org.xml.sax.ContentHandler;
 import org.xml.sax.SAXException;
 import org.xml.sax.helpers.XMLFilterImpl;
 import com.sun.xml.bind.v2.runtime.unmarshaller.SAXConnector;

 public class NamespaceFilter extends XMLFilterImpl {
    private SAXConnector saxConnector;

    @Override
    public void startElement(String uri, String localName, String qName, Attributes atts) throws SAXException {
        if(saxConnector != null) {
            Collection<QName> expected = saxConnector.getContext().getCurrentExpectedElements();
            for(QName expectedQname : expected) {
                if(localName.equals(expectedQname.getLocalPart())) {
                    super.startElement(expectedQname.getNamespaceURI(), localName, qName, atts);
                    return;
                }
            }
        }
        super.startElement(uri, localName, qName, atts);
    }

    @Override
    public void setContentHandler(ContentHandler handler) {
        super.setContentHandler(handler);
        if(handler instanceof SAXConnector) {
            saxConnector = (SAXConnector) handler;
        }
    }
}

Believe me, I've tried so hard to find a decent IDE for Android developement but I failed. I used Visual Studio for many years, and it is so hard for me to get use to the way Eclipse doing things.

However, the new IntelliJ supports for Android development, it's the closest you can get.

df$Gene <- as.factor(df$Gene)
do.call(rbind, lapply(split(df,df$Gene), function(x) {return(x[which.max(x$Value),])}))

Just using base R

Update 2019: Using Fetch:

fetch('http://localhost/foo.txt')
  .then(response => response.text())
  .then((data) => {
    console.log(data)
  })

https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API

Create an Extension Method most likely you will want to use this more than once and this prevents duplicate code.

Implementation:

 public static void AddRange<T, S>(this Dictionary<T, S> source, Dictionary<T, S> collection)
 {
        if (collection == null)
        {
            throw new ArgumentNullException("Collection is null");
        }

        foreach (var item in collection)
        {
            if(!source.ContainsKey(item.Key)){ 
               source.Add(item.Key, item.Value);
            }
            else
            {
               // handle duplicate key issue here
            }  
        } 
 }

Usage:

Dictionary<string,string> animals = new Dictionary<string,string>();
Dictionary<string,string> newanimals = new Dictionary<string,string>();

animals.AddRange(newanimals);

This is one of the very good and step by step process to set up PostgreSQL in ubuntu server. I have tried it with Ubuntu 16.04 and its working.

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

Maybe it does not fit to your code but i found out if you have a code snippet like this:

@SpringBootApplication
public class SpringBootApacheKafkaApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringBootApacheKafkaApplication.class,args).close();
    }
}

then just remove the close() method. That's fixed my problem! Maybe I can help someone with that

You can use php code in files with extension .php and only there (iff other is not defined in your server settings).

Just rename your file *.html to *.php

If you want to allow php code processing in files of different format, you have two options to do that:

1) Modifying httpd.conf to allow this for all projects on your server, by adding:

AddHandler application/x-httpd-php .htm .html

2) Creating .htaccess file in your separate project top directory with:

<Files />
    AddType application/x-httpd-php .html
</Files>

For second option you need to allow use of .htaccess files in your httpd.conf, by adding the following settings:

AllowOverride All
AccessFileName .htaccess

*that is correct for Apache HTTP Server

SQL> select substr('999123456789', greatest (-9, -length('999123456789')), 9) as value from dual;

VALUE
---------
123456789

SQL> select substr('12345', greatest (-9,  -length('12345')), 9) as value from dual;

VALUE
----
12345

The call to greatest (-9, -length(string)) limits the starting offset either 9 characters left of the end or the beginning of the string.

Here is some C code that produces the above mentioned error:

int main(int argc, char **argv) {
  exit(1);
}

Compiled like this on Fedora 17 Linux 64 bit with gcc:

el@defiant ~/foo2 $ gcc -o n n2.c                                                               
n2.c: In function ‘main’:
n2.c:2:3: warning: incompatible implicit declaration of built-in 
function ‘exit’ [enabled by default]
el@defiant ~/foo2 $ ./n 
el@defiant ~/foo2 $ 

To make the warning go away, add this declaration to the top of the file:

#include <stdlib.h>

I happened to notice the solution given below. In found it my research for the same issue. I don't who had posted it but it wasn't made by me. It uses jQuery:

$(document).ready(function() {
    $(":checkbox").bind("click", false);
});

This would make the checkboxes read only which would be helpful for showing readonly data to the client.

Ross has the right idea for POSTing the usual parameter/value format to a url.

I recently ran into a situation where I needed to POST some XML as Content-Type "text/xml" without any parameter pairs so here's how you do that:

$xml = '<?xml version="1.0"?><stuff><child>foo</child><child>bar</child></stuff>';
$httpRequest = curl_init();

curl_setopt($httpRequest, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($httpRequest, CURLOPT_HTTPHEADER, array("Content-Type:  text/xml"));
curl_setopt($httpRequest, CURLOPT_POST, 1);
curl_setopt($httpRequest, CURLOPT_HEADER, 1);

curl_setopt($httpRequest, CURLOPT_URL, $url);
curl_setopt($httpRequest, CURLOPT_POSTFIELDS, $xml);

$returnHeader = curl_exec($httpRequest);
curl_close($httpRequest);

In my case, I needed to parse some values out of the HTTP response header so you may not necessarily need to set CURLOPT_RETURNTRANSFER or CURLOPT_HEADER.

$("input[type=checkbox]").on("change", function() { 

    if (this.checked) {

      //do your stuff

     }
});

Since the number of columns is a constant, you can just have an List of int[].

    import java.util.*;
    //...

    List<int[]> rowList = new ArrayList<int[]>();

    rowList.add(new int[] { 1, 2, 3 });
    rowList.add(new int[] { 4, 5, 6 });
    rowList.add(new int[] { 7, 8 });

    for (int[] row : rowList) {
        System.out.println("Row = " + Arrays.toString(row));
    } // prints:
      // Row = [1, 2, 3]
      // Row = [4, 5, 6]
      // Row = [7, 8]

    System.out.println(rowList.get(1)[1]); // prints "5"

Since it's backed by a List, the number of rows can grow and shrink dynamically. Each row is backed by an int[], which is static, but you said that the number of columns is fixed, so this is not a problem.

What is the best approach to do this JAVA?

I would personally NOT use Axis 2, even for client side development only. Here is why I stay away from it:

1. I don't like its architecture and hate its counter productive deployment model.
2. I find it to be low quality project.
3. I don't like its performances (see this benchmark against JAX-WS RI).
4. It's always a nightmare to setup dependencies (I use Maven and I always have to fight with the gazillion of dependencies) (see #2)
5. Axis sucked big time and Axis2 isn't better. No, this is not a personal opinion, there is a consensus.
6. I suffered once, never again.

The only reason Axis is still around is IMO because it's used in Eclipse since ages. Thanks god, this has been fixed in Eclipse Helios and I hope Axis2 will finally die. There are just much better stacks.

I read about SAAJ, looks like that will be more granular level of approach?

To do what?

Is there any other way than using the WSDL2Java tool, to generate the code. Maybe wsimport in another option. What are the pros and cons?

Yes! Prefer a JAX-WS stack like CXF or JAX-WS RI (you might also read about Metro, Metro = JAX-WS RI + WSIT), they are just more elegant, simpler, easier to use. In your case, I would just use JAX-WS RI which is included in Java 6 and thus wsimport.

Can someone send the links for some good tutorials on these topics?

That's another pro, there are plenty of (good quality) tutorials for JAX-WS, see for example:

• Developing JAX-WS Web Service Clients (start here)
• Introducing JAX-WS 2.0 With the Java SE 6 Platform, Part 1
• Creating a Simple Web Service and Client with JAX-WS
• Creating a SOAP client with either Apache CXF or GlassFish Metro (Glen Mazza's blog is a great resources)

What are the options we need to use while generating the code using the WSDL2Java?

No options, use wsimport :)

You can return json in PHP this way:

header('Content-Type: application/json');
echo json_encode(array('foo' => 'bar'));
exit;

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

sed is used for removing full paths of symlinked file/folder path coming after ->

Unfortunately, tabs are lost. Using zsh I am able to preserve tabs.

!/usr/bin/env bash

#!/usr/bin/env zsh

F1='index-2.md' #With hyperlinks
F2='index.md'

if [ -e $F1 ];then
    rm $F1
fi

if [ -e $F2 ];then
    rm $F2
fi

DATA=`tree --dirsfirst -t -Rl --noreport | \
    sed 's/->.*$//g'`             # Remove symlink adress and ->

echo -e '```\n' ${DATA} '\n```' > $F1  # Markdown needs triple back ticks for <pre>

# With the power of piping, creating HTML tree than pipe it
# to html2markdown program, creates cool markdown file with hyperlinks.

DATA=`tree --dirsfirst -t -Rl --noreport -H http://guneysu.pancakeapps.com`
echo $DATA | \
    sed 's/\r\r/\n/g' | \
    html2markdown | \
    sed '/^\s*$/d' | \
    sed 's/\# Directory Tree//g' | \

According to AWS documentation [https://aws.amazon.com/premiumsupport/knowledge-center/instance-store-vs-ebs/] instance store volumes is not persistent through instance stops, terminations, or hardware failures. Any AMI created from instance stored disk doesn't contain data present in instance store so all instances launched by this AMI will not have data stored in instance store. Instance store can be used as cache for applications running on instance, for all persistent data you should use EBS.

A simple implementation could consist of:

• A buffer, implemented as an array of size n, of whatever type you need
• A read pointer or index (whichever is more efficient for your processor)
• A write pointer or index
• A counter indicating how much data is in the buffer (derivable from the read and write pointers, but faster to track it separately)

Every time you write data, you advance the write pointer and increment the counter. When you read data, you increase the read pointer and decrement the counter. If either pointer reaches n, set it to zero.

You can't write if counter = n. You can't read if counter = 0.

Just use: android:layout_centerHorizontal="true"

It will put the whole textview in the center

Android Device Monitor was deprecated in Android Studio 3.1 and removed from Android Studio 3.2. To start the standalone Device Monitor application in Android Studio 3.1 and lower you can run android-sdk/tools/monitor.bat

Try redirecting the output like this:

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose >$null 2>&1

Simply use this method.

<?php
    $_SESSION['foo'] = 'bar'; // set session 
    print $_SESSION['foo']; //print it
    unset($_SESSION['foo']); //unset session 
?>

To avoid division by zero!

function x = normalize(x, eps)
    % Normalize vector `x` (zero mean, unit variance)

    % default values
    if (~exist('eps', 'var'))
        eps = 1e-6;
    end

    mu = mean(x(:));

    sigma = std(x(:));
    if sigma < eps
        sigma = 1;
    end

    x = (x - mu) / sigma;
end

Just thought I'd add that I've improved Mud's SimplerAES by adding a random IV that's passed back inside the encrypted string. This improves the encryption as encrypting the same string will result in a different output each time.

public class StringEncryption
{
    private readonly Random random;
    private readonly byte[] key;
    private readonly RijndaelManaged rm;
    private readonly UTF8Encoding encoder;

    public StringEncryption()
    {
        this.random = new Random();
        this.rm = new RijndaelManaged();
        this.encoder = new UTF8Encoding();
        this.key = Convert.FromBase64String("Your+Secret+Static+Encryption+Key+Goes+Here=");
    }

    public string Encrypt(string unencrypted)
    {
        var vector = new byte[16];
        this.random.NextBytes(vector);
        var cryptogram = vector.Concat(this.Encrypt(this.encoder.GetBytes(unencrypted), vector));
        return Convert.ToBase64String(cryptogram.ToArray());
    }

    public string Decrypt(string encrypted)
    {
        var cryptogram = Convert.FromBase64String(encrypted);
        if (cryptogram.Length < 17)
        {
            throw new ArgumentException("Not a valid encrypted string", "encrypted");
        }

        var vector = cryptogram.Take(16).ToArray();
        var buffer = cryptogram.Skip(16).ToArray();
        return this.encoder.GetString(this.Decrypt(buffer, vector));
    }

    private byte[] Encrypt(byte[] buffer, byte[] vector)
    {
        var encryptor = this.rm.CreateEncryptor(this.key, vector);
        return this.Transform(buffer, encryptor);
    }

    private byte[] Decrypt(byte[] buffer, byte[] vector)
    {
        var decryptor = this.rm.CreateDecryptor(this.key, vector);
        return this.Transform(buffer, decryptor);
    }

    private byte[] Transform(byte[] buffer, ICryptoTransform transform)
    {
        var stream = new MemoryStream();
        using (var cs = new CryptoStream(stream, transform, CryptoStreamMode.Write))
        {
            cs.Write(buffer, 0, buffer.Length);
        }

        return stream.ToArray();
    }
}

And bonus unit test

[Test]
public void EncryptDecrypt()
{
    // Arrange
    var subject = new StringEncryption();
    var originalString = "Testing123!£$";

    // Act
    var encryptedString1 = subject.Encrypt(originalString);
    var encryptedString2 = subject.Encrypt(originalString);
    var decryptedString1 = subject.Decrypt(encryptedString1);
    var decryptedString2 = subject.Decrypt(encryptedString2);

    // Assert
    Assert.AreEqual(originalString, decryptedString1, "Decrypted string should match original string");
    Assert.AreEqual(originalString, decryptedString2, "Decrypted string should match original string");
    Assert.AreNotEqual(originalString, encryptedString1, "Encrypted string should not match original string");
    Assert.AreNotEqual(encryptedString1, encryptedString2, "String should never be encrypted the same twice");
}

Use this -

create table dummy_table_name as select * from source_table_name;

This will create the new table with existing data available on source_table_name.

From the kubernetes docs:

https://kubernetes.io/docs/concepts/containers/images/#updating-images

The default pull policy is IfNotPresent which causes the Kubelet to skip pulling an image if it already exists. If you would like to always force a pull, you can do one of the following:

• set the imagePullPolicy of the container to Always;
• use :latest as the tag for the image to use;
• enable the AlwaysPullImages admission controller.

Or read the other way: Using the :latest tag forces images to always be pulled. If you use the eval $(minikube docker-env) as mentioned above, then either don't use any tag, or assign a tag to your local image you can avoid Kubernetes trying to forcibly pull it.

A backslash needs to be escaped with another backslash.

print('\\')

The above is correct if we assume that arrays can contain only strings, but arrays can contain other arrays as well. Also in_array() function can accept an array for $needle, so strtolower($needle) is not going to work if $needle is an array and array_map('strtolower', $haystack) is not going to work if $haystack contains other arrays, but will result in "PHP warning: strtolower() expects parameter 1 to be string, array given".

Example:

$needle = array('p', 'H');
$haystack = array(array('p', 'H'), 'U');

So i created a helper class with the releveant methods, to make case-sensitive and case-insensitive in_array() checks. I am also using mb_strtolower() instead of strtolower(), so other encodings can be used. Here's the code:

class StringHelper {

public static function toLower($string, $encoding = 'UTF-8')
{
    return mb_strtolower($string, $encoding);
}

/**
 * Digs into all levels of an array and converts all string values to lowercase
 */
public static function arrayToLower($array)
{
    foreach ($array as &$value) {
        switch (true) {
            case is_string($value):
                $value = self::toLower($value);
                break;
            case is_array($value):
                $value = self::arrayToLower($value);
                break;
        }
    }
    return $array;
}

/**
 * Works like the built-in PHP in_array() function — Checks if a value exists in an array, but
 * gives the option to choose how the comparison is done - case-sensitive or case-insensitive
 */
public static function inArray($needle, $haystack, $case = 'case-sensitive', $strict = false)
{
    switch ($case) {
        default:
        case 'case-sensitive':
        case 'cs':
            return in_array($needle, $haystack, $strict);
            break;
        case 'case-insensitive':
        case 'ci':
            if (is_array($needle)) {
                return in_array(self::arrayToLower($needle), self::arrayToLower($haystack), $strict);
            } else {
                return in_array(self::toLower($needle), self::arrayToLower($haystack), $strict);
            }
            break;
    }
}

If you are using Spring boot and have this issue with the OffsetDateTime then need to use the registerModules as answered above by @greperror(answered May 28 '16 at 13:04) but note that there is one difference. The dependency mentioned doesn't need to be added as I am guessing that spring boot has it already. I was having this issue with Spring boot and it worked for me without adding this dependency.

If you don't have Your own Data Class, then you can design your map as follows

Map<Integer, Object> map=new HashMap<Integer, Object>();

Here don't forget to use "instanceof" operator while retrieving the values from MAP.

If you have your own Data class then then you can design your map as follows

Map<Integer, YourClassName> map=new HashMap<Integer, YourClassName>();

import java.util.Date;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;


public class HashMapTest {
public static void main(String[] args) {
    Map<Integer,Demo> map=new HashMap<Integer, Demo>();
    Demo d1= new Demo(1,"hi",new Date(),1,1);
    Demo d2= new Demo(2,"this",new Date(),2,1);
    Demo d3= new Demo(3,"is",new Date(),3,1);
    Demo d4= new Demo(4,"mytest",new Date(),4,1);
    //adding values to map
    map.put(d1.getKey(), d1);
    map.put(d2.getKey(), d2);
    map.put(d3.getKey(), d3);
    map.put(d4.getKey(), d4);
    //retrieving values from map
    Set<Integer> keySet= map.keySet();
    for(int i:keySet){
        System.out.println(map.get(i));
    }
    //searching key on map
    System.out.println(map.containsKey(d1.getKey()));
    //searching value on map
    System.out.println(map.containsValue(d1));
}

}
class Demo{
    private int key;
    private String message;
    private Date time;
    private int count;
    private int version;

    public Demo(int key,String message, Date time, int count, int version){
        this.key=key;
        this.message = message;
        this.time = time;
        this.count = count;
        this.version = version;
    }
    public String getMessage() {
        return message;
    }
    public Date getTime() {
        return time;
    }
    public int getCount() {
        return count;
    }
    public int getVersion() {
        return version;
    }
    public int getKey() {
        return key;
    }
    @Override
    public String toString() {
        return "Demo [message=" + message + ", time=" + time

While Guy's answer is correct (and probably fits 9 out of 10 cases), it's worth noting that if you are attempting to do this from a control that already has its DataContext set further up the stack, you'll resetting this when you set DataContext back to itself:

DataContext="{Binding RelativeSource={RelativeSource Self}}"

This will of course then break your existing bindings.

If this is the case, you should set the RelativeSource on the control you are trying to bind, rather than its parent.

i.e. for binding to a UserControl's properties:

Binding Path=PropertyName, 
        RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}

Given how difficult it can be currently to see what's going on with data binding, it's worth bearing this in mind even if you find that setting RelativeSource={RelativeSource Self} currently works :)

V1.1 Bugfix: null pointer if JAVA_TOOL_OPTIONS is not set

From this paper: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2006/n2049.pdf

for( type-speci?er-seq simple-declarator : expression ) statement

is syntactically equivalent to

{
    typedef decltype(expression) C;
    auto&& rng(expression);
    for (auto begin(std::For<C>::begin(rng)), end(std::For<C>::end(rng)); begin != end; ++ begin) {
        type-speci?er-seq simple-declarator(*begin);
        statement
    }
}

So you can clearly see that what is abc in your case will be std::pair<key_type, value_type >. So for printing you can do access each element by abc.first and abc.second

See ReceivedTime Property

http://msdn.microsoft.com/en-us/library/office/aa171873(v=office.11).aspx

You added another \ to the end of C:\Temp\ in the SaveAs File line. Could be a problem. Do a test first before adding a path separator.

dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  
saveFolder = "C:\Temp"

You have not set objAtt so there is no need for "Set objAtt = Nothing". If there was it would be just before End Sub not in the loop.

Public Sub saveAttachtoDisk (itm As Outlook.MailItem) 
    Dim objAtt As Outlook.Attachment 
    Dim saveFolder As String Dim dateFormat
    dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  saveFolder = "C:\Temp"
    For Each objAtt In itm.Attachments
        objAtt.SaveAsFile saveFolder & "\" & dateFormat & objAtt.DisplayName
    Next
End Sub

This is usually due to Security settings. It is a "trap" set for first time users to allow macros then take it away. http://www.slipstick.com/outlook-developer/how-to-use-outlooks-vba-editor/

Here is an article with full details on how to do this.

Private Sub btnScale_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles btnScale.Click
    ' Get the scale factor.
    Dim scale_factor As Single = Single.Parse(txtScale.Text)

    ' Get the source bitmap.
    Dim bm_source As New Bitmap(picSource.Image)

    ' Make a bitmap for the result.
    Dim bm_dest As New Bitmap( _
        CInt(bm_source.Width * scale_factor), _
        CInt(bm_source.Height * scale_factor))

    ' Make a Graphics object for the result Bitmap.
    Dim gr_dest As Graphics = Graphics.FromImage(bm_dest)

    ' Copy the source image into the destination bitmap.
    gr_dest.DrawImage(bm_source, 0, 0, _
        bm_dest.Width + 1, _
        bm_dest.Height + 1)

    ' Display the result.
    picDest.Image = bm_dest
End Sub

[Edit]
One more on the similar lines.

SELECT DATEADD(DD,-DATEPART(DY,GETDATE())+1,GETDATE())

Regardless of how do you index the pushbacks your vector contains 10 elements indexed from 0 (0, 1, ..., 9). So in your second loop v[j] is invalid, when j is 10.

This will fix the error:

for(int j = 9;j >= 0;--j)
{
    cout << v[j];
}

In general it's better to think about indexes as 0 based, so I suggest you change also your first loop to this:

for(int i = 0;i < 10;++i)
{
    v.push_back(i);
}

Also, to access the elements of a container, the idiomatic approach is to use iterators (in this case: a reverse iterator):

for (vector<int>::reverse_iterator i = v.rbegin(); i != v.rend(); ++i)
{
    std::cout << *i << std::endl;
}

(I'm going to ignore handling input, its just a distraction.)

The easy way is to sort it.

#include <stdlib.h>
#include <stdio.h>

int cmp_int( const void *a, const void *b ) {
    return *(int*)a - *(int*)b;
}

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    const int n = sizeof(a) / sizeof(a[0]);

    qsort(a, n, sizeof(a[0]), cmp_int);
    printf("%d %d\n", a[n-1], a[n-2]);
}

But that isn't the most efficient because it's O(n log n), meaning as the array gets bigger the number of comparisons gets bigger faster. Not too fast, slower than exponential, but we can do better.

We can do it in O(n) or "linear time" meaning as the array gets bigger the number of comparisons grows at the same rate.

Loop through the array tracking the max, that's the usual way to find the max. When you find a new max, the old max becomes the 2nd highest number.

Instead of having a second loop to find the 2nd highest number, throw in a special case for running into the 2nd highest number.

#include <stdio.h>
#include <limits.h>

int main() {
    int a[] = { 1, 5, 3, 2, 0, 5, 7, 6 };
    // This trick to get the size of an array only works on stack allocated arrays.
    const int n = sizeof(a) / sizeof(a[0]);

    // Initialize them to the smallest possible integer.
    // This avoids having to special case the first elements.
    int max = INT_MIN;
    int second_max = INT_MIN;

    for( int i = 0; i < n; i++ ) {
        // Is it the max?
        if( a[i] > max ) {
            // Make the old max the new 2nd max.
            second_max = max;
            // This is the new max.
            max = a[i];
        }
        // It's not the max, is it the 2nd max?
        else if( a[i] > second_max ) {
            second_max = a[i];
        }
    }

    printf("max: %d, second_max: %d\n", max, second_max);
}

There might be a more elegant way to do it, but that will do, at most, 2n comparisons. At best it will do n.

Note that there's an open question of what to do with { 1, 2, 3, 3 }. Should that return 3, 3 or 2, 3? I'll leave that to you to decide and adjust accordingly.

I found that when within a Miniconda3 environment I had to run:

conda deactivate

Neither deactivate nor source deactivate worked for me.

Look at the filter function.

If you just need a 1-pole low-pass filter, it's

xfilt = filter(a, [1 a-1], x);

where a = T/τ, T = the time between samples, and τ (tau) is the filter time constant.

Here's the corresponding high-pass filter:

xfilt = filter([1-a a-1],[1 a-1], x);

If you need to design a filter, and have a license for the Signal Processing Toolbox, there's a bunch of functions, look at fvtool and fdatool.

Another simple way to rotate an ImageView:
UPDATE:
Required imports:

import android.graphics.Matrix;
import android.widget.ImageView;

Code: (Assuming imageView, angle, pivotX & pivotY are already defined)

Matrix matrix = new Matrix();
imageView.setScaleType(ImageView.ScaleType.MATRIX);   //required
matrix.postRotate((float) angle, pivotX, pivotY);
imageView.setImageMatrix(matrix);

This method does not require creating a new bitmap each time.

NOTE: To rotate an ImageView on ontouch at runtime you can set onTouchListener on ImageView & rotate it by adding last two lines(i.e. postRotate matrix & set it on imageView) in above code section in your touch listener ACTION_MOVE part.

This is a simple script I used in Python but it can be easily adapted. Nothing fancy though.

def occurance(arr):
  results = []
  for n in arr:
      data = {}
      data["point"] = n
      data["count"] = 0
      for i in range(0, len(arr)):
          if n == arr[i]:
              data["count"] += 1
      results.append(data)
  return results

Sorry for my bad English. Checking Mails using Python with MAPI is easier,

outlook =win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
folder = outlook.Folders[5]
Subfldr = folder.Folders[5]
messages_REACH = Subfldr.Items
message = messages_REACH.GetFirst()

Here we can get the most first mail into the Mail box, or into any sub folder. Actually, we need to check the Mailbox number & orientation. With the help of this analysis we can check each mailbox & its sub mailbox folders.

Similarly please find the below code, where we can see, the last/ earlier mails. How we need to check.

`outlook =win32com.client.Dispatch("Outlook.Application").GetNamespace("MAPI")
folder = outlook.Folders[5]
Subfldr = folder.Folders[5]
messages_REACH = Subfldr.Items
message = messages_REACH.GetLast()`

With this we can get most recent email into the mailbox. According to the above mentioned code, we can check our all mail boxes, & its sub folders.

    <style>
    background: url(images/Untitled-2.fw.png);
background-repeat:no-repeat;
background-position:center;
background-size: cover;
    </style>

If you need to see the output of the execute, use CALL together with or instead of START.

Example:

CALL "C:\Program Files\Certain Directory\file.exe" -param PAUSE

This will run the file.exe and print back whatever it outputs, in the same command window. Remember the PAUSE after the call or else the window may close instantly.

If the radio buttons are added dynamically, you may wish to use this

$(document).on('change', 'input[type=radio][name=bedStatus]', function (event) {
    switch($(this).val()) {
      case 'allot' :
        alert("Allot Thai Gayo Bhai");
        break;
      case 'transfer' :
        alert("Transfer Thai Gayo");
        break;
    }     
});

Is there a way for a site to tell the browser not to offer to remember passwords?

The website tells the browser that it is a password by using <input type="password">. So if you must do this from a website perspective then you would have to change that. (Obviously I don't recommend this).

The best solution would be to have the user configure their browser so it won't remember passwords.

you can also

include Rails.application.routes.url_helpers

from inside a console sessions to access the helpers:

url_for controller: :users, only_path: true
users_path
# => '/users'

or

Rails.application.routes.url_helpers.users_path

For your copy and paste ease

' add item to array
Function AddItem(arr, val)
    ReDim Preserve arr(UBound(arr) + 1)
    arr(UBound(arr)) = val
    AddItem = arr
End Function

Used like so

a = Array()
a = AddItem(a, 5)
a = AddItem(a, "foo")

If your test project is set to target a 64bit platform, the tests won't show up in the NUnit Test Adapter.

More readable way of achieving this (not a fan of single line ansible tasks)

- local_action: 
    module: copy 
    content: "{{ foo_result }}"
    dest: /path/to/destination/file

To expand on Ross Allen's answer, here is a slightly cleaner variant using ES6 arrow syntax.

{this.props.titles.map(title =>
  <th key={title}>{title}</th>
)}

It has the advantage that the JSX part is isolated (no return or ;), making it easier to put a loop around it.

Here is a simple way to define those constants, and I'm pretty sure it's portable:

const double inf = 1.0/0.0;
const double nan = 0.0/0.0;

When I run this code:

printf("inf  = %f\n", inf);
printf("-inf = %f\n", -inf);
printf("nan  = %f\n", nan);
printf("-nan = %f\n", -nan);

I get:

inf  = inf
-inf = -inf
nan  = -nan
-nan = nan

I think this is what you need if I'm understanding you correctly:

<div id="wrapperHeader">
 <div id="header">
  <img src="images/logo.png" alt="logo" />
 </div> 
</div>



div#wrapperHeader {
 width:100%;
 height;200px; /* height of the background image? */
 background:url(images/header.png) repeat-x 0 0;
 text-align:center;
}

div#wrapperHeader div#header {
 width:1000px;
 height:200px;
 margin:0 auto;
}

div#wrapperHeader div#header img {
 width:; /* the width of the logo image */
 height:; /* the height of the logo image */
 margin:0 auto;
}

A small addendum: you do not have to create your own name for the key, android provides these, f.ex. Intent.EXTRA_TEXT. Modifying the accepted answer:

Intent i = new Intent(FirstScreen.this, SecondScreen.class);   
String strName = null;
i.putExtra(Intent.EXTRA_TEXT, strName);

Then, to retrieve the value try something like:

String newString;
Bundle extras = getIntent().getExtras();
if(extras == null) {
    newString= null;
} else {
    newString= extras.getString(Intent.EXTRA_TEXT);
}

    }
}

then drag this class to you jframe,and it's done

it's deprecated,but it works.........

I fixed the issue without changing the python path as that did not seem like the right solution for me. The following solution worked for me, hopefully it works for you as well :))

1. Open cmd in windows / shell in Linux/Mac.

2. Activate your virtualenv (using source activate / activate.bat / activate.ps1 if using power shell)

   C:\Users\<myUserName>\Videos\myFolder>django-project\Scripts\activate.bat (django-project) C:\Users\<myUserName>\Videos\myFolder>

3. Navigate to your project directory and open vscode there.

   (django-project) C:\Users\prash\Videos\myFolder\projects>code .

4. in VS Code, goto File --> Preferences --> Settings (dont worry you dont need to open the json file)

5. In the setting search bar search for virtual / venv and hit enter. You should find the below in the search bar:

Python: Venv Folders Folders in your home directory to look into for virtual environments (supports pyenv, direnv and virtualenvwrapper by default).

6. Add item, and then enter the path of the scripts of your virtuanenv which has the activate file in it. For example in my system, it is:

   C:\Users\<myUserName>\Videos\myFolder\django-project\Scripts\

7. Save it and restart VS Code.

8. To restart, open cmd again, navigate to your project path and open vs code. (Note that your venv should be activated in cmd before you open vs code from cmd)

Command to open vs code from cmd:

code .

I would also take a look at CloudMade's developer tools. They offer a beautifully styled OSM base map service, an OpenLayers plugin, and even their own light-weight, very fast JavaScript mapping client. They also host their own routing service, which you mentioned as a possible requirement. They have great documentation and examples.

Result:

you are asking about Geocoder. Google provide an API for this. so does another provider for this.

you can see the demo of implementation in My Current Location .net

Insert into TBL (Name, UserName, Password) Output Inserted.IdentityColumnName

A simple one would be

\d{4}-\d{2}-\d{2}

Debuggex Demo

but this does not restrict month to 1-12 and days from 1 to 31.

There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.

Apart from all the other answers, what you can do is :

long l = Long.parseLong("600851475143");

for example :

obj.function(Long.parseLong("600851475143"));

As mentionned in comments, this is the updated solution in favor of Icon object with documentation.

Use Icon object

var icon = {
    url: "../res/sit_marron.png", // url
    scaledSize: new google.maps.Size(50, 50), // scaled size
    origin: new google.maps.Point(0,0), // origin
    anchor: new google.maps.Point(0, 0) // anchor
};

 posicion = new google.maps.LatLng(latitud,longitud)
 marker = new google.maps.Marker({
  position: posicion,
  map: map,
  icon: icon
 });

var listItems= "";
var jsonData = jsonObj.d;
    for (var i = 0; i < jsonData.Table.length; i++){
      listItems+= "<option value='" + jsonData.Table[i].stateid + "'>" + jsonData.Table[i].statename + "</option>";
    }
    $("#<%=DLState.ClientID%>").html(listItems);

Example

   <html>
    <head></head>
    <body>
      <select id="DLState">
      </select>
    </body>
    </html>

    /*javascript*/
    var jsonList = {"Table" : [{"stateid" : "2","statename" : "Tamilnadu"},
                {"stateid" : "3","statename" : "Karnataka"},
                {"stateid" : "4","statename" : "Andaman and Nicobar"},
                 {"stateid" : "5","statename" : "Andhra Pradesh"},
                 {"stateid" : "6","statename" : "Arunachal Pradesh"}]}

    $(document).ready(function(){
      var listItems= "";
      for (var i = 0; i < jsonList.Table.length; i++){
        listItems+= "<option value='" + jsonList.Table[i].stateid + "'>" + jsonList.Table[i].statename + "</option>";
      }
      $("#DLState").html(listItems);
    });    

This is not explicitly mentioned, but based on the following docs, I think it is implied that an app needs to declare and implement a BackupAgent in order for data backup to work, even in the case when allowBackup is set to true (which is the default value).

Here's what I get.

I'm using Visual Studio Code and its Terminal to execute the 'npm' commands.

Visual Studio Code (not as administrator)
PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator)
Run this command after I've run something like 'ng serve'

PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator - closing and opening the IDE)
If I have already executed other commands that would impact node modules I decided to try closing Visual Studio Code first, opening it up as Administrator then running the command:

PS g:\labs\myproject> npm install bootstrap@3

Result I get then is: + [email protected]
added 115 packages and updated 1 package in 24.685s

This is not a permanent solution since I don't want to continue closing down VS Code every time I want to execute an npm command, but it did resolve the issue to a point.

Working with position:absolute; along with flex:

Position the flex item with position: relative. Then inside of it, add another <div> element with:

position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;

This extends the element to the boundaries of its relative-positioned parent, but does not allow to extend it. Inside, overflow: auto; will then work as expected.

setRetainInstance() - Deprecated

As Fragments Version 1.3.0-alpha01

The setRetainInstance() method on Fragments has been deprecated. With the introduction of ViewModels, developers have a specific API for retaining state that can be associated with Activities, Fragments, and Navigation graphs. This allows developers to use a normal, not retained Fragment and keep the specific state they want retained separate, avoiding a common source of leaks while maintaining the useful properties of a single creation and destruction of the retained state (namely, the constructor of the ViewModel and the onCleared() callback it receives).

Url Encoding is easy in .NET. Use:

System.Web.HttpUtility.UrlEncode(string url)

If that'll be decoded to get the folder name, you'll still need to exclude characters that can't be used in folder names (*, ?, /, etc.)

2016 update

With the latest release of Google Play Services, v7.8, you have access to the new Mobile Vision API. That's probably the most convenient way to implement barcode scanning now, and it also works offline.

From the Android Barcode API:

The Barcode API detects barcodes in real-time, on device, in any orientation. It can also detect multiple barcodes at once.

It reads the following barcode formats:

• 1D barcodes: EAN-13, EAN-8, UPC-A, UPC-E, Code-39, Code-93, Code-128, ITF, Codabar
• 2D barcodes: QR Code, Data Matrix, PDF-417, AZTEC

It automatically parses QR Codes, Data Matrix, PDF-417, and Aztec values, for the following supported formats:

• URL
• Contact information (VCARD, etc.)
• Calendar event
• Email
• Phone
• SMS
• ISBN
• WiFi
• Geo-location (latitude and longitude)
• AAMVA driver license/ID

I was looking for a pure CSS solution using img tags (not the background image way).

I found this brilliant way to achieve the goal on crop thumbnails with css:

.thumbnail {
  position: relative;
  width: 200px;
  height: 200px;
  overflow: hidden;
}
.thumbnail img {
  position: absolute;
  left: 50%;
  top: 50%;
  height: 100%;
  width: auto;
  -webkit-transform: translate(-50%,-50%);
      -ms-transform: translate(-50%,-50%);
          transform: translate(-50%,-50%);
}
.thumbnail img.portrait {
  width: 100%;
  height: auto;
}

It is similar to @Nathan Redblur's answer but it allows for portrait images, too.

Works like a charm for me. The only thing you need to know about the image is whether it is portrait or landscape in order to set the .portrait class so I had to use a bit of Javascript for this part.

Unfortunately, I'm bound by very strict policies on the disclosure of source code by my employer, so I can't provide actual code. But for my taste the best solution is to create a subclass overriding Popen.wait() to poll instead of wait indefinitely, and Popen.__init__ to accept a timeout parameter. Once you do that, all the other Popen methods (which call wait) will work as expected, including communicate.

Type hints are for maintainability and don't get interpreted by Python. In the code below, the line def add(self, ic:int) doesn't result in an error until the next return... line:

class C1:
    def __init__(self):
        self.idn = 1
    def add(self, ic: int):
        return self.idn + ic

c1 = C1()
c1.add(2)

c1.add(c1)

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<input>", line 5, in add
TypeError: unsupported operand type(s) for +: 'int' and 'C1'

If you are using postgres use text wherever you can, unless you have a size constraint since there is no performance penalty for text vs varchar

There is no performance difference among these three types, apart from increased storage space when using the blank-padded type, and a few extra CPU cycles to check the length when storing into a length-constrained column. While character(n) has performance advantages in some other database systems, there is no such advantage in PostgreSQL; in fact character(n) is usually the slowest of the three because of its additional storage costs. In most situations text or character varying should be used instead

PostsgreSQL manual

Initially when i implemented a longClick and a click to perform two separate events the problem i face was that when i had a longclick , the application also performed the action to be performed for a simple click . The solution i realized was to change the return type of the longClick to true which is normally false by default . Change it and it works perfectly .

Rather than escaping all characters in a string that have particular significance in the pattern syntax given that you are using a leading wildcard in the pattern it is quicker and easier just to do.

SELECT * 
FROM YourTable
WHERE CHARINDEX(@myString , YourColumn) > 0

In cases where you are not using a leading wildcard the approach above should be avoided however as it cannot use an index on YourColumn.

Additionally in cases where the optimum execution plan will vary according to the number of matching rows the estimates may be better when using LIKE with the square bracket escaping syntax when compared to both CHARINDEX and the ESCAPE keyword.

Though not POSIX, bash 4 has the &> operator:

command &> alloutput.txt

One other difference:

• "adb shell input" is calling the input.jar to process and send the keycode from the Java layer of the android framework.
• "adb sendevent" is actually c code (part of toolbox utility ) that sends the input code directly into the /dev/input.... of Linux input subsystem.

More detail code trace into inside AOSP Framework can be found here:

Database name is a value of SqlConnectionStringBuilder.InitialCatalog property.

The best way to get all friends (who are using the App too, of course) with correct picture sizes is to use field expansion, either with one of the size tags (square, small, normal, large):

/me/friends?fields=picture.type(large)

(edit: this does not work anymore)

...or you can specify the width/height:

me/friends?fields=picture.width(100).height(100)

Btw, you can also write it like this:

me?fields=friends{picture.type(large)}

Short and simple implementation in Kotlin, with nullable support:

Add methods to Parcel

fun Parcel.writeBoolean(flag: Boolean?) {
    when(flag) {
        true -> writeInt(1)
        false -> writeInt(0)
        else -> writeInt(-1)
    }
}

fun Parcel.readBoolean(): Boolean? {
    return when(readInt()) {
        1 -> true
        0 -> false
        else -> null
    }
}

And use it:

parcel.writeBoolean(isUserActive)

parcel.readBoolean()        // For true, false, null
parcel.readBoolean()!!      // For only true and false

You'll need to deal with File System Object. See this OpenTextFile method sample.

The first button is always the default; it can't be changed. Whilst you can try to fix it up with JavaScript, the form will behave unexpectedly in a browser without scripting, and there are some usability/accessibility corner cases to think about. For example, the code linked to by Zoran will accidentally submit the form on Enter press in a <input type="button">, which wouldn't normally happen, and won't catch IE's behaviour of submitting the form for Enter press on other non-field content in the form. So if you click on some text in a <p> in the form with that script and press Enter, the wrong button will be submitted... especially dangerous if, as given in that example, the real default button is ‘Delete’!

My advice would be to forget about using scripting hacks to reassign defaultness. Go with the flow of the browser and just put the default button first. If you can't hack the layout to give you the on-screen order you want, then you can do it by having a dummy invisible button first in the source, with the same name/value as the button you want to be default:

<input type="submit" class="defaultsink" name="COMMAND" value="Save" />

.defaultsink {
    position: absolute; left: -100%;
}

(note: positioning is used to push the button off-screen because display: none and visibility: hidden have browser-variable side-effects on whether the button is taken as default and whether it's submitted.)

Struggling with this myself. This is my take:

https://gist.github.com/2639448:

require 'csv'

class CSV
  def CSV.unparse array
    CSV.generate do |csv|
      array.each { |i| csv << i }
    end

CSV.unparse [ %w(your array), %w(goes here) ]

You could use Jquery indeed or plain good old javascript:

var opacityPercent=30;
document.getElementById("id").style.cssText="opacity:0."+opacityPercent+"; filter:progid:DXImageTransform.Microsoft.Alpha(style=0,opacity="+opacityPercent+");";

You put this in a function that you call on a setTimeout until the desired opacity is reached

I believe the best solution for this, is what I use, and that is a natural css border:

border-right:1px solid;

You might need to take care of padding like:

padding-left: 5px;
padding-right: 5px;

Finally, if you don't want the last li to have that seperating border, give it's last-child "none" in "border-right" like this:

li:last-child{
  border-right:none;
}

Good luck :)
