I've seen sloppy code that looks like this:

serrno = errno;
some_Syscall(...)
if (serrno != errno)
/* sound alarm: CATROSTOPHIC ERROR !!! */

You should check to see if this is what is happening in the python code. Errno is only valid if the proceeding system call failed.

Edited to add:

You don't say how long this process lives. Possible consumers of memory

• forked processes
• unused data structures
• shared libraries
• memory mapped files

You can add one option to your build for production:

-localWorkers 8 – Where 8 is the number of concurrent threads that calculate permutations. All you have to do is to adjust this number to the number that is more convenient to you. See GWT compilation performance (thanks to Dennis Ich comment).

If you are compiling to the testing environment, you can also use:

-draftCompile which enables faster, but less-optimized compilations

-optimize 0 which does not optimize your code (9 is the max optimization value)

Another thing that more than doubled the build and hosted mode performance was the use of an SSD disk (now hostedmode works like a charm). It's not an cheap solution, but depending on how much you use GWT and the cost of your time, it may worth it!

Hope this helps you!

I think you should casting variable or use Integer class by call out method doubleValue().

You can use hh to tell printf that the argument is an unsigned char. Use 0 to get zero padding and 2 to set the width to 2. x or X for lower/uppercase hex characters.

uint8_t a = 0x0a;
printf("%02hhX", a); // Prints "0A"
printf("0x%02hhx", a); // Prints "0x0a"

Edit: If readers are concerned about 2501's assertion that this is somehow not the 'correct' format specifiers I suggest they read the printf link again. Specifically:

Even though %c expects int argument, it is safe to pass a char because of the integer promotion that takes place when a variadic function is called.

The correct conversion specifications for the fixed-width character types (int8_t, etc) are defined in the header <cinttypes>(C++) or <inttypes.h> (C) (although PRIdMAX, PRIuMAX, etc is synonymous with %jd, %ju, etc).

As for his point about signed vs unsigned, in this case it does not matter since the values must always be positive and easily fit in a signed int. There is no signed hexideximal format specifier anyway.

Edit 2: ("when-to-admit-you're-wrong" edition):

If you read the actual C11 standard on page 311 (329 of the PDF) you find:

hh: Specifies that a following d, i, o, u, x, or X conversion specifier applies to a signed char or unsigned char argument (the argument will have been promoted according to the integer promotions, but its value shall be converted to signed char or unsigned char before printing); or that a following n conversion specifier applies to a pointer to a signed char argument.

<ion-col size="12">
  <ion-card class="box-shadow ion-text-center background-size"
  *ngIf="data != null"
  [ngStyle]="{'background-image': 'url(' + data.headerImage + ')'}">

  </ion-card>

Following is the list of conversion characters that you may use in the printf:

%d – for signed decimal integer

%f – for the floating point

%o – octal number

%c – for a character

%s – a string

%i – use for integer base 10

%u – for unsigned decimal number

%x – hexadecimal number

%% – for writing % (percentage)

%n – for new line = \n

Here's a solution for finding the last row, last column, or last cell. It addresses the A1 R1C1 Reference Style dilemma for the column it finds. Wish I could give credit, but can't find/remember where I got it from, so "Thanks!" to whoever it was that posted the original code somewhere out there.

    MsgBox "The last cell found is: " & Last(3, ActiveSheet.Cells)
    MsgBox "The last column (A1) found is: " & Last(4, ActiveSheet.Cells)
End Sub

Use the basename method of the path module:

var path = require('path');
var filename = path.basename(__filename);
console.log(filename);

Here is the documentation the above example is taken from.

As Dan pointed out, Node is working on ECMAScript modules with the "--experimental-modules" flag. Node 12 still supports __dirname and __filename as above.

If you are using the --experimental-modules flag, there is an alternative approach.

The alternative is to get the path to the current ES module:

const __filename = new URL(import.meta.url).pathname;

And for the directory containing the current module:

import path from 'path';

const __dirname = path.dirname(new URL(import.meta.url).pathname);

In your adapter class make Integer variable as index and assign it to "0" (if you want to select 1st item by default, if not assign "-1").Then on your onBindViewHolder method,

@Override
public void onBindViewHolder(@NonNull final ViewHolder holder, final int position) {
    holder.texttitle.setText(listTitle.get(position));
    holder.itemView.setTag(listTitle.get(position));
    holder.texttitle.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            index = position;
            notifyDataSetChanged();
        }
    });
    if (index == position)
        holder.texttitle.setTextColor(mContext.getResources().getColor(R.color.selectedColor));
    else
        holder.texttitle.setTextColor(mContext.getResources().getColor(R.color.unSelectedColor));
}

Thats it and you are good to go.in If condition true section place your selected color or what ever you need, and else section place unselected color or what ever.

If you are using bootstrap 3, use tag, like this <small><span class="glyphicon glyphicon-send"></span></small> It works perfect for Bootstrap 3.
You can even use multiple <small> tags to set the size more smaller.
Code:
<small><small><span class="glyphicon glyphicon-send"></span></small></small>

It is also possible to pass environment variables explicitly through ssh. It does require some server-side set-up through, so this this not a universal answer.

In my case, I wanted to pass a backup repository encryption key to a command on the backup storage server without having that key stored there, but note that any environment variable is visible in ps! The solution of passing the key on stdin would work as well, but I found it too cumbersome. In any case, here's how to pass an environment variable through ssh:

On the server, edit the sshd_config file, typically /etc/ssh/sshd_config and add an AcceptEnv directive matching the variables you want to pass. See man sshd_config. In my case, I want to pass variables to borg backup so I chose:

AcceptEnv BORG_*

Now, on the client use the -o SendEnv option to send environment variables. The following command line sets the environment variable BORG_SECRET and then flags it to be sent to the client machine (called backup). It then runs printenv there and filters the output for BORG variables:

$ BORG_SECRET=magic-happens ssh -o SendEnv=BORG_SECRET backup printenv | egrep BORG
BORG_SECRET=magic-happens

You are running the [ (aka test) command with the argument "false", not running the command false. Since "false" is a non-empty string, the test command always succeeds. To actually run the command, drop the [ command.

if false; then
   echo "True"
else
   echo "False"
fi

People have suggested many great solutions here, but I used this simple technique with my EditText (nothing in java and AnroidManifest.xml is required). Just set your focusable and focusableInTouchMode to false directly on EditText.

 <EditText
        android:id="@+id/text_pin"
        android:layout_width="136dp"
        android:layout_height="wrap_content"
        android:layout_margin="5dp"
        android:textAlignment="center"
        android:inputType="numberPassword"
        android:password="true"
        android:textSize="24dp"
        android:focusable="false"
        android:focusableInTouchMode="false"/>

My intent here is to use this edit box in App lock activity where I am asking user to input the PIN and I want to show my custom PIN pad. Tested with minSdk=8 and maxSdk=23 on Android Studio 2.1

For big file use the following code (you are less memory hungry)

Parallel.ForEach(File.ReadLines(txtProxyListPath.Text), line => {
    //Your stuff
});

This might not be applicable to all scenarios, but I found that the position: sticky (same thing with position: fixed) only works on old iPhones when the scrolling container is not the body, but inside something else.

Example pseudo html:

body                         <- scrollbar
   relative div
       sticky div

The sticky div will be sticky on desktop browsers, but with certain devices, tested with: Chromium: dev tools: device emultation: iPhone 6/7/8, and with Android 4 Firefox, it will not.

What will work, however, is

body
    div overflow=auto       <- scrollbar
        relative div
            sticky div

In general, the best way to find any file in any arbitrary location is to start a terminal window and type in the classic Unix command "find":

find / -name index.html -print

Since the file you're looking for is the root file in the root directory of your web server, it's probably easier to find your web server's document root. For example, look under:

/var/www/*

Or type:

find /var/www -name index.html -print

Let's give an example for int(10) one with zerofill keyword, one not, the table likes that:

create table tb_test_int_type(
    int_10 int(10),
    int_10_with_zf int(10) zerofill,
    unit int unsigned
);

Let's insert some data:

insert into tb_test_int_type(int_10, int_10_with_zf, unit)
values (123456, 123456,3147483647), (123456, 4294967291,3147483647) 
;

Then

select * from tb_test_int_type; 

# int_10, int_10_with_zf, unit
'123456', '0000123456', '3147483647'
'123456', '4294967291', '3147483647'

We can see that

• with keyword zerofill, num less than 10 will fill 0, but without zerofill it won't

• Secondly with keyword zerofill, int_10_with_zf becomes unsigned int type, if you insert a minus you will get error Out of range value for column...... But you can insert minus to int_10. Also if you insert 4294967291 to int_10 you will get error Out of range value for column.....

Conclusion:

1. int(X) without keyword zerofill, is equal to int range -2147483648~2147483647

2. int(X) with keyword zerofill, the field is equal to unsigned int range 0~4294967295, if num's length is less than X it will fill 0 to the left

For those who landed here and are searching for a solution that merges N arrays AND also sums the values of identical keys found in the N arrays, I've written this function that works recursively as well. (See: https://gist.github.com/Nickology/f700e319cbafab5eaedc)

Example:

$a = array( "A" => "bob", "sum" => 10, "C" => array("x","y","z" => 50) );
$b = array( "A" => "max", "sum" => 12, "C" => array("x","y","z" => 45) );
$c = array( "A" => "tom", "sum" =>  8, "C" => array("x","y","z" => 50, "w" => 1) );

print_r(array_merge_recursive_numeric($a,$b,$c));

Will result in:

Array
(
    [A] => tom
    [sum] => 30
    [C] => Array
        (
            [0] => x
            [1] => y
            [z] => 145
            [w] => 1
        )

)

Here's the code:

on OSX assure you have launched the Docker application before issuing

docker ps

or docker build ... etc ... yes it seems strange and somewhat misleading that issuing

docker --version

gives version even though the docker daemon is not running ... ditto for those other version cmds ... I just encountered exactly the same symptoms ... this behavior on OSX is different from on linux

Below code worked for me

  $today_start = Carbon::now()->format('Y-m-d 00:00:00');
        $today_end = Carbon::now()->format('Y-m-d 23:59:59');

        $start_activity = MarketingActivity::whereBetween('created_at', [$today_start, $today_end])
                            ->orderBy('id', 'ASC')->limit(1)->get();

I'd be cautious as dismissing something as a bad idea because it is slow. If it is a part of the code that does not take much time to execute then the slowness is irrelevant. I just used the following code:

for (ic in 1:(dim(centroid)[2]))
{
cluster[[ic]]=matrix(,nrow=2,ncol=0)
}
# code to identify cluster=pindex[ip] to which to add the point
if(pdist[ip]>-1)
{
cluster[[pindex[ip]]]=cbind(cluster[[pindex[ip]]],points[,ip])
}

for a problem that ran in less than 1 second.

You can use the EL 3.0 Stream API.

<div>${attachments.stream().findFirst().get()}</div>

Be careful! The EL 3.0 Stream API was finalized before the Java 8 Stream API and it is different than that. They can't sunc both apis because it will break the backward compatibility.

I used concat method and works well.

concat(//SomeElement/text(),'_',//OtherElement/text())

svn:// doesn't talk http, therefor there's nothing a http proxy could do.

Any reason why http doesn't work? Have you considered https? If you really need it, you probably have to have port 3690 opened in your firewall.

I've got the same issue, my model is binding from another form, I've added ng-change and ng-model and it still doesn't work:

<input type="hidden" id="pdf-url" class="form-control" ng-model="pdfUrl"/>

<ng-dropzone
  dropzone="dropzone"
  dropzone-config="dropzoneButtonCfg"
  model="pdfUrl">
</ng-dropzone>

An input #pdf-url gets data from dropzone (two ways binding), however, ng-change doesn't work in this case. $scope.$watch is a solution for me:

$scope.$watch('pdfUrl', function updatePdfUrl(newPdfUrl, oldPdfUrl) {
  if (newPdfUrl !== oldPdfUrl) {
    // It's updated - Do something you want here.
  }
});

Hope this help.

Yes you can and lodash is not needed... i.e.

for (var key in myObject.options) {
  // check also if property is not inherited from prototype
  if (myObject.options.hasOwnProperty(key)) { 
    var value = myObject.options[key];
  }
}

Edit: the accepted answer (_.forOwn()) should be https://stackoverflow.com/a/21311045/528262

i = ['title', 'email', 'password2', 'password1', 'first_name', 
     'last_name', 'next', 'newsletter']
a, b = i.index('password2'), i.index('password1')
i[b], i[a] = i[a], i[b]

If you are comfortable with keeping passwords in plain text files, another option is to use a JSON file with the --extra-vars parameter (be sure to exclude the file from source control):

ansible-playbook --extra-vars "@private_vars.json" playbook.yml 

Ansible has supported this option since 1.3.

This is because the element hadn't been loaded at the time when the bundle js was being executed.

I'd move the <script src="sample.js" type="text/javascript"></script> to the very bottom of the index.html file. This way you can ensure script is executed after all the html elements have been parsed and rendered .

• Struct members are stored in the order they are declared. (This is required by the C99 standard, as mentioned here earlier.)
• If necessary, padding is added before each struct member, to ensure correct alignment.
• Each primitive type T requires an alignment of sizeof(T) bytes.

So, given the following struct:

struct ST
{
   char ch1;
   short s;
   char ch2;
   long long ll;
   int i;
};

• ch1 is at offset 0
• a padding byte is inserted to align...
• s at offset 2
• ch2 is at offset 4, immediately after s
• 3 padding bytes are inserted to align...
• ll at offset 8
• i is at offset 16, right after ll
• 4 padding bytes are added at the end so that the overall struct is a multiple of 8 bytes. I checked this on a 64-bit system: 32-bit systems may allow structs to have 4-byte alignment.

So sizeof(ST) is 24.

It can be reduced to 16 bytes by rearranging the members to avoid padding:

struct ST
{
   long long ll; // @ 0
   int i;        // @ 8
   short s;      // @ 12
   char ch1;     // @ 14
   char ch2;     // @ 15
} ST;

There is no such thing as :touch in the W3C specifications, http://www.w3.org/TR/CSS2/selector.html#pseudo-class-selectors

:active should work, I would think.

Order on the :active/:hover pseudo class is important for it to function correctly.

Here is a quote from that above link

Interactive user agents sometimes change the rendering in response to user actions. CSS provides three pseudo-classes for common cases:

• The :hover pseudo-class applies while the user designates an element (with some pointing device), but does not activate it. For example, a visual user agent could apply this pseudo-class when the cursor (mouse pointer) hovers over a box generated by the element. User agents not supporting interactive media do not have to support this pseudo-class. Some conforming user agents supporting interactive media may not be able to support this pseudo-class (e.g., a pen device).
• The :active pseudo-class applies while an element is being activated by the user. For example, between the times the user presses the mouse button and releases it.
• The :focus pseudo-class applies while an element has the focus (accepts keyboard events or other forms of text input).

Yes, you will have no problems using:

if (BuildConfig.DEBUG) {
   //It's not a release version.
}

Unless you are importing the wrong BuildConfig class. Make sure you are referencing your project's BuildConfig class, not from any of your dependency libraries.

Why all these bit shifting operations and need for library functions? If you have the value the OP posted: 1011110 and you want to know if the bit in the 3rd position from the right is set, just do:

int temp = 0b1011110;
if( temp & 4 )   /* or (temp & 0b0100) if that's how you roll */
  DoSomething();

Or, something that may be more easily interpreted by future readers of the code with no #include needed:

int temp = 0b1011110;
_Bool bThirdBitIsSet = (temp & 4) ? 1 : 0;
if( bThirdBitIsSet )
  DoSomething();

Or if you like it to look a bit prettier:

#include <stdbool.h>
int temp = 0b1011110;
bool bThirdBitIsSet = (temp & 4) ? true : false;
if( bThirdBitIsSet )
  DoSomething();

I've just been fighting with this today. Let's call the behavior of removing the extra line breaks "continuation." A little experimenting finds the following behavior:

• Every message starts with continuation off.
• Lines less than 40 characters long do not trigger continuation, but if continuation is on, they will have their line breaks removed.
• Lines 40 characters or longer turn continuation on. It remains on until an event occurs to turn it off.
• Lines that end with a period, question mark, exclamation point or colon turn continuation off. (Outlook assumes it's the end of a sentence?)
• Lines that turn continuation off will start with a line break, but will turn continuation back on if they are longer than 40 characters.
• Lines that start or end with a tab turn continuation off.
• Lines that start with 2 or more spaces turn continuation off.
• Lines that end with 3 or more spaces turn continuation off.

Please note that I tried all of this with Outlook 2007. YMMV.
So if possible, end all bullet items with a sentence-terminating punctuation mark, a tab, or even three spaces.

Rather than trying to address the resource as a File just ask the ClassLoader to return an InputStream for the resource instead via getResourceAsStream:

InputStream in = getClass().getResourceAsStream("/file.txt"); 
BufferedReader reader = new BufferedReader(new InputStreamReader(in));

As long as the file.txt resource is available on the classpath then this approach will work the same way regardless of whether the file.txt resource is in a classes/ directory or inside a jar.

The URI is not hierarchical occurs because the URI for a resource within a jar file is going to look something like this: file:/example.jar!/file.txt. You cannot read the entries within a jar (a zip file) like it was a plain old File.

This is explained well by the answers to:

• How do I read a resource file from a Java jar file?
• Java Jar file: use resource errors: URI is not hierarchical

You need to set Div2 to Div1's innerHTML. Also, JavaScript is case sensitive - in your HTML, the id Div2 is DIV2. Also, you should use document, not Document:

var MyDiv1 = document.getElementById('DIV1');
var MyDiv2 = document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Here is a JSFiddle: http://jsfiddle.net/gFN6r/.

You should check for Dictionary.ContainsKey(int key) before trying to pull out the value.

Dictionary<int, int> myDictionary = new Dictionary<int, int>();
myDictionary.Add(2,4);
myDictionary.Add(3,5);

int keyToFind = 7;
if(myDictionary.ContainsKey(keyToFind))
{
    myValueLookup = myDictionay[keyToFind];
    // do work...
}
else
{
    // the key doesn't exist.
}

SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE());

Example.

SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE()); 

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

I tried this tool and it gave me good results.

Introduction

You can get everything through ExternalContext. In JSF 1.x, you can get the raw HttpServletResponse object by ExternalContext#getResponse(). In JSF 2.x, you can use the bunch of new delegate methods like ExternalContext#getResponseOutputStream() without the need to grab the HttpServletResponse from under the JSF hoods.

On the response, you should set the Content-Type header so that the client knows which application to associate with the provided file. And, you should set the Content-Length header so that the client can calculate the download progress, otherwise it will be unknown. And, you should set the Content-Disposition header to attachment if you want a Save As dialog, otherwise the client will attempt to display it inline. Finally just write the file content to the response output stream.

Most important part is to call FacesContext#responseComplete() to inform JSF that it should not perform navigation and rendering after you've written the file to the response, otherwise the end of the response will be polluted with the HTML content of the page, or in older JSF versions, you will get an IllegalStateException with a message like getoutputstream() has already been called for this response when the JSF implementation calls getWriter() to render HTML.

Turn off ajax / don't use remote command!

You only need to make sure that the action method is not called by an ajax request, but that it is called by a normal request as you fire with <h:commandLink> and <h:commandButton>. Ajax requests and remote commands are handled by JavaScript which in turn has, due to security reasons, no facilities to force a Save As dialogue with the content of the ajax response.

In case you're using e.g. PrimeFaces <p:commandXxx>, then you need to make sure that you explicitly turn off ajax via ajax="false" attribute. In case you're using ICEfaces, then you need to nest a <f:ajax disabled="true" /> in the command component.

Generic JSF 2.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    ExternalContext ec = fc.getExternalContext();

    ec.responseReset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    ec.setResponseContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ExternalContext#getMimeType() for auto-detection based on filename.
    ec.setResponseContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    ec.setResponseHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = ec.getResponseOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Generic JSF 1.x example

public void download() throws IOException {
    FacesContext fc = FacesContext.getCurrentInstance();
    HttpServletResponse response = (HttpServletResponse) fc.getExternalContext().getResponse();

    response.reset(); // Some JSF component library or some Filter might have set some headers in the buffer beforehand. We want to get rid of them, else it may collide.
    response.setContentType(contentType); // Check http://www.iana.org/assignments/media-types for all types. Use if necessary ServletContext#getMimeType() for auto-detection based on filename.
    response.setContentLength(contentLength); // Set it with the file size. This header is optional. It will work if it's omitted, but the download progress will be unknown.
    response.setHeader("Content-Disposition", "attachment; filename=\"" + fileName + "\""); // The Save As popup magic is done here. You can give it any file name you want, this only won't work in MSIE, it will use current request URL as file name instead.

    OutputStream output = response.getOutputStream();
    // Now you can write the InputStream of the file to the above OutputStream the usual way.
    // ...

    fc.responseComplete(); // Important! Otherwise JSF will attempt to render the response which obviously will fail since it's already written with a file and closed.
}

Common static file example

In case you need to stream a static file from the local disk file system, substitute the code as below:

File file = new File("/path/to/file.ext");
String fileName = file.getName();
String contentType = ec.getMimeType(fileName); // JSF 1.x: ((ServletContext) ec.getContext()).getMimeType(fileName);
int contentLength = (int) file.length();

// ...

Files.copy(file.toPath(), output);

Common dynamic file example

In case you need to stream a dynamically generated file, such as PDF or XLS, then simply provide output there where the API being used expects an OutputStream.

E.g. iText PDF:

String fileName = "dynamic.pdf";
String contentType = "application/pdf";

// ...

Document document = new Document();
PdfWriter writer = PdfWriter.getInstance(document, output);
document.open();
// Build PDF content here.
document.close();

E.g. Apache POI HSSF:

String fileName = "dynamic.xls";
String contentType = "application/vnd.ms-excel";

// ...

HSSFWorkbook workbook = new HSSFWorkbook();
// Build XLS content here.
workbook.write(output);
workbook.close();

Note that you cannot set the content length here. So you need to remove the line to set response content length. This is technically no problem, the only disadvantage is that the enduser will be presented an unknown download progress. In case this is important, then you really need to write to a local (temporary) file first and then provide it as shown in previous chapter.

Utility method

If you're using JSF utility library OmniFaces, then you can use one of the three convenient Faces#sendFile() methods taking either a File, or an InputStream, or a byte[], and specifying whether the file should be downloaded as an attachment (true) or inline (false).

public void download() throws IOException {
    Faces.sendFile(file, true);
}

Yes, this code is complete as-is. You don't need to invoke responseComplete() and so on yourself. This method also properly deals with IE-specific headers and UTF-8 filenames. You can find source code here.

If you want to defined your own function, try this:

function explode (delimiter, string, limit) {
  if (arguments.length < 2 ||
    typeof delimiter === 'undefined' ||
    typeof string === 'undefined') {
    return null
  }
  if (delimiter === '' ||
    delimiter === false ||
    delimiter === null) {
    return false
  }
  if (typeof delimiter === 'function' ||
    typeof delimiter === 'object' ||
    typeof string === 'function' ||
    typeof string === 'object') {
    return {
      0: ''
    }
  }
  if (delimiter === true) {
    delimiter = '1'
  }

  // Here we go...
  delimiter += ''
  string += ''

  var s = string.split(delimiter)

  if (typeof limit === 'undefined') return s

  // Support for limit
  if (limit === 0) limit = 1

  // Positive limit
  if (limit > 0) {
    if (limit >= s.length) {
      return s
    }
    return s
      .slice(0, limit - 1)
      .concat([s.slice(limit - 1)
        .join(delimiter)
      ])
  }

  // Negative limit
  if (-limit >= s.length) {
    return []
  }

  s.splice(s.length + limit)
  return s
}

DO
$do$
BEGIN
   IF EXISTS (SELECT FROM orders) THEN
      DELETE FROM orders;
   ELSE

There are no procedural elements in standard SQL. The IF statement is part of the default procedural language PL/pgSQL. You need to create a function or execute an ad-hoc statement with the DO command.

You need a semicolon (;) at the end of each statement in plpgsql (except for the final END).

You need END IF; at the end of the IF statement.

A sub-select must be surrounded by parentheses:

    IF (SELECT count(*) FROM orders) > 0 ...

Or:

    IF (SELECT count(*) > 0 FROM orders) ...

This is equivalent and much faster, though:

    IF EXISTS (SELECT FROM orders) ...

Alternative

The additional SELECT is not needed. This does the same, faster:

DO
$do$
BEGIN
   DELETE FROM orders;
   IF NOT FOUND THEN
      INSERT INTO orders VALUES (1,2,3);
   END IF;
END
$do$

Though unlikely, concurrent transactions writing to the same table may interfere. To be absolutely sure, write-lock the table in the same transaction before proceeding as demonstrated.

As @Alex McMillan mentioned, use state to dictate what should be rendered in the dom.

In the example below I have an input field and I want to add a second one when the user clicks the button, the onClick event handler calls handleAddSecondInput( ) which changes inputLinkClicked to true. I am using a ternary operator to check for the truthy state, which renders the second input field

class HealthConditions extends React.Component {
  constructor(props) {
    super(props);


    this.state = {
      inputLinkClicked: false
    }
  }

  handleAddSecondInput() {
    this.setState({
      inputLinkClicked: true
    })
  }


  render() {
    return(
      <main id="wrapper" className="" data-reset-cookie-tab>
        <div id="content" role="main">
          <div className="inner-block">

            <H1Heading title="Tell us about any disabilities, illnesses or ongoing conditions"/>

            <InputField label="Name of condition"
              InputType="text"
              InputId="id-condition"
              InputName="condition"
            />

            {
              this.state.inputLinkClicked?

              <InputField label=""
                InputType="text"
                InputId="id-condition2"
                InputName="condition2"
              />

              :

              <div></div>
            }

            <button
              type="button"
              className="make-button-link"
              data-add-button=""
              href="#"
              onClick={this.handleAddSecondInput}
            >
              Add a condition
            </button>

            <FormButton buttonLabel="Next"
              handleSubmit={this.handleSubmit}
              linkto={
                this.state.illnessOrDisability === 'true' ?
                "/404"
                :
                "/add-your-details"
              }
            />

            <BackLink backLink="/add-your-details" />

          </div>
         </div>
      </main>
    );
  }
}

I used Fiddler as a proxy. Fiddler redirects localhost calls to a external server.

I configured Firefox to use manual proxy (127.0.0.1 port 8888). Fiddler capture the calls and redirect them to another server, by using URL filters.

None of the up-voted answers work for me. Finally I pass the credentials inside the python script, using the client API.

import boto3
client = boto3.client(
's3',
aws_access_key_id=ACCESS_KEY,
aws_secret_access_key=SECRET_KEY,
aws_session_token=SESSION_TOKEN)

Please notice that the aws_session_token argument is optional. Not recommended for public work, but make life easier for simple trial.

As @haserman says:

TelephonyManager tManager = (TelephonyManager)myActivity.getSystemService(Context.TELEPHONY_SERVICE);
String uid = tManager.getDeviceId();

But it's necessary including the permission in the manifest file:

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

Microsoft recommends using singular for Enums unless the Enum represents bit fields (use the FlagsAttribute as well). See Enumeration Type Naming Conventions (a subset of Microsoft's Naming Guidelines).

To respond to your clarification, I see nothing wrong with either of the following:

public enum OrderStatus { Pending, Fulfilled, Error };

public class SomeClass { 
    public OrderStatus OrderStatus { get; set; }
}

or

public enum OrderStatus { Pending, Fulfilled, Error };

public class SomeClass {
    public OrderStatus Status { get; set; }
}

The easiest way I have tested just add a <br> as in the following:

<div class="col-sm-6">
    <br><h3><p class="text-center">Some Text</p></h3>
</div>

The only problem is that a extra line break (generated by that <br>) is generated when the screen gets smaller and it stacks. But it is quick and simple.

Try one of these:

1. Use column alias:

   ORDER BY RadioServiceCodeId,RadioService

2. Use column position:

   ORDER BY 1,2

You can only order by columns that actually appear in the result of the DISTINCT query - the underlying data isn't available for ordering on.

What if you know the type will be an enum, but you don't know what the exact type is at compile time?

public class EnumHelper
{
    public static IEnumerable<T> GetValues<T>()
    {
        return Enum.GetValues(typeof(T)).Cast<T>();
    }

    public static IEnumerable getListOfEnum(Type type)
    {
        MethodInfo getValuesMethod = typeof(EnumHelper).GetMethod("GetValues").MakeGenericMethod(type);
        return (IEnumerable)getValuesMethod.Invoke(null, null);
    }
}

The method getListOfEnum uses reflection to take any enum type and returns an IEnumerable of all enum values.

Usage:

Type myType = someEnumValue.GetType();

IEnumerable resultEnumerable = getListOfEnum(myType);

foreach (var item in resultEnumerable)
{
    Console.WriteLine(String.Format("Item: {0} Value: {1}",item.ToString(),(int)item));
}

POSSIBLE CAUSES

• Number of th elements in the table header or footer differs from number of columns in the table body or defined using columns option.
• Attribute colspan is used for th element in the table header.
• Incorrect column index specified in columnDefs.targets option.

SOLUTIONS

• Make sure that number of th elements in the table header or footer matches number of columns defined in the columns option.
• If you use colspan attribute in the table header, make sure you have at least two header rows and one unique th element for each column. See Complex header for more information.
• If you use columnDefs.targets option, make sure that zero-based column index refers to existing columns.

In Swift:

For example, name of your custom class is InfoView

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

import Foundation
import UIKit

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

Then set File's Owner to UIViewController like this:

Rename your View to InfoView:

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

Make sure that class name is InfoView:

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

And usage of this custom class in your MainViewController:

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

Another option might be to avoid WCF all-together and just use a .NET HttpHandler. The HttpHandler can grab the query-string variables from your GET and just write back a response to the Java code.

Use a CASE statement and do it like this:

SELECT 
    T1.Id [Id]
    ,CASE WHEN T2.Id IS NOT NULL THEN 'TRUE' ELSE 'FALSE' END [Has Foreign Key in T2]
FROM
    TABLE1 [T1]
    LEFT OUTER JOIN
        TABLE2 [T2]
        ON
        T2.Id = T1.Id

I'm calling powershell from cmd, and passing quotes and neither escapes here worked. The grave accent worked to escape double quotes on this Win 10 surface pro.

>powershell.exe "echo la`"" >> test
>type test

Below are outputs I got for other characters to escape a double quote:

la\
la^
la
la~

Using another quote to escape a quote resulted in no quotes. As you can see, the characters themselves got typed, but didn't escape the double quotes.

I checked the source code you provided on GitHub. There were several mistakes / typos in the configuration.

In CustomerDbConfig / OrderDbConfig you should refer to customerEntityManager and packages should point at existing packages:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "customerEntityManager",
    transactionManagerRef = "customerTransactionManager",
    basePackages = {"com.mm.boot.multidb.repository.customer"})
public class CustomerDbConfig {

The packages to scan in customerEntityManager and orderEntityManager were both not pointing at proper package:

em.setPackagesToScan("com.mm.boot.multidb.model.customer");

Also the injection of proper EntityManagerFactory did not work. It should be:

@Bean(name = "customerTransactionManager")
public PlatformTransactionManager transactionManager(EntityManagerFactory customerEntityManager){

}

The above was causing the issue and the exception. While providing the name in a @Bean method you are sure you get proper EMF injected.

The last thing I have done was to disable to automatic configuration of JpaRepositories:

@EnableAutoConfiguration(exclude = JpaRepositoriesAutoConfiguration.class)

And with all fixes the application starts as you probably expect!

CSS has different pseudo selector by which you can achieve such effect. In your case you can use

:active : if you want background color only when the button is clicked and don't want to persist.

:focus: if you want background color untill the focus is on the button.

button:active{
    background:olive;
}

and

button:focus{
    background:olive;
}

Here's the fixes to get it to run in Windows without rebuilding everything - such as if you do not have a recent version of MS-VS. (You will need a Win32 C++ compiler, but you can install MS VS Community Edition free.)

I've tried this with Spark 1.2.2 and mahout 0.10.2 as well as with the latest versions in November 2015. There are a number of problems including the fact that the Scala code tries to run a bash script (mahout/bin/mahout) which does not work of course, the sbin scripts have not been ported to windows, and the winutils are missing if hadoop is not installed.

(1) Install scala, then unzip spark/hadoop/mahout into the root of C: under their respective product names.

(2) Rename \mahout\bin\mahout to mahout.sh.was (we will not need it)

(3) Compile the following Win32 C++ program and copy the executable to a file named C:\mahout\bin\mahout (that's right - no .exe suffix, like a Linux executable)

#include "stdafx.h"
#define BUFSIZE 4096
#define VARNAME TEXT("MAHOUT_CP")
int _tmain(int argc, _TCHAR* argv[]) {
    DWORD dwLength;     LPTSTR pszBuffer;
    pszBuffer = (LPTSTR)malloc(BUFSIZE*sizeof(TCHAR));
    dwLength = GetEnvironmentVariable(VARNAME, pszBuffer, BUFSIZE);
    if (dwLength > 0) { _tprintf(TEXT("%s\n"), pszBuffer); return 0; }
    return 1;
}

(4) Create the script \mahout\bin\mahout.bat and paste in the content below, although the exact names of the jars in the _CP class paths will depend on the versions of spark and mahout. Update any paths per your installation. Use 8.3 path names without spaces in them. Note that you cannot use wildcards/asterisks in the classpaths here.

set SPARK_HOME=C:\spark

The name of the variable MAHOUT_CP should not be changed, as it is referenced in the C++ code.

Of course you can comment-out the code that launches the Spark master and worker because Mahout will run Spark as-needed; I just put it in the batch job to show you how to launch it if you wanted to use Spark without Mahout.

(5) The following tutorial is a good place to begin:

https://mahout.apache.org/users/sparkbindings/play-with-shell.html

You can bring up the Mahout Spark instance at:

"C:\Program Files (x86)\Google\Chrome\Application\chrome" --disable-web-security http://localhost:4040

There's a few approaches for this:

1. Create a char array then use Arrays.fill, and finally convert to a String
2. Iterate through a loop adding a space each time
3. Use String.format

Or maybe and that is prob it

<img src="path" onclick="this.src='path'">

Open command prompt with admin access and type the following commands there .

a)

tasklist

it displays list of all available services . There you can see the service you want to stop/start/restart . Remember PID value of the service you want to force stop.

b) Now type

taskkill /f /PID [PID value of the service] 

and press enter. On success you will get the message “SUCCESS: The process with PID has been terminated”.

Ex : taskkill /f /PID 5088

This will forcibly kill the frozen service. You can now return to Server Manager and restart the service.

app.put('url', function(req, res) {

        // use our bear model to find the bear we want
        Bear.findById(req.params.bear_id, function(err, bear) {

            if (err)
                res.send(err);

            bear.name = req.body.name;  // update the bears info

            // save the bear
            bear.save(function(err) {
                if (err)
                    res.send(err);

                res.json({ message: 'Bear updated!' });
            });

        });
    });

Here is a better approach to solving the update method in mongoose, you can check Scotch.io for more details. This definitely worked for me!!!

This should be faster and will preserve the original order:

seen = {}
new_list = [seen.setdefault(x, x) for x in my_list if x not in seen]

If you don't care about order, you can just:

new_list = list(set(my_list))

Dependency walker works on normal win32 binaries. All .NET dll's and exe's have a small stub header part which makes them look like normal binaries, but all it basically says is "load the CLR" - so that's all that dependency walker will tell you.

To see which things your .NET app actually relies on, you can use the tremendously excellent .NET reflector from Red Gate. (EDIT: Note that .NET Reflector is now a paid product. ILSpy is free and open source and very similar.)

Load your DLL into it, right click, and chose 'Analyze' - you'll then see a "Depends On" item which will show you all the other dll's (and methods inside those dll's) that it needs.

It can sometimes get trickier though, in that your app depends on X dll, and X dll is present, but for whatever reason can't be loaded or located at runtime.

To troubleshoot those kinds of issues, Microsoft have an Assembly Binding Log Viewer which can show you what's going on at runtime

Temporal types are the set of time-based types that can be used in persistent state mappings.

The list of supported temporal types includes the three java.sql types java.sql.Date, java.sql.Time, and java.sql.Timestamp, and it includes the two java.util types java.util.Date and java.util.Calendar.

The java.sql types are completely hassle-free. They act just like any other simple mapping type and do not need any special consideration.

The two java.util types need additional metadata, however, to indicate which of the JDBC java.sql types to use when communicating with the JDBC driver. This is done by annotating them with the @Temporal annotation and specifying the JDBC type as a value of the TemporalType enumerated type.

There are three enumerated values of DATE, TIME, and TIMESTAMP to represent each of the java.sql types.

For iOS 6 and above, use the following to allow multiple lines:

button.titleLabel.lineBreakMode = NSLineBreakByWordWrapping;
// you probably want to center it
button.titleLabel.textAlignment = NSTextAlignmentCenter; // if you want to 
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

For iOS 5 and below use the following to allow multiple lines:

button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;
// you probably want to center it
button.titleLabel.textAlignment = UITextAlignmentCenter;
[button setTitle: @"Line1\nLine2" forState: UIControlStateNormal];

2017, for iOS9 forward,

generally, just do these two things:

1. choose "Attributed Text"
2. on the "Line Break" popup select "Word Wrap"

Yeah that can be quite complicated since the * is used for many different purposes in C/C++.

If * appears in front of an already declared variable/function, it means either that:

• a) * gives access to the value of that variable (if the type of that variable is a pointer type, or overloaded the * operator).
• b) * has the meaning of the multiply operator, in that case, there has to be another variable to the left of the *

If * appears in a variable or function declaration it means that that variable is a pointer:

int int_value = 1;
int * int_ptr; //can point to another int variable
int   int_array1[10]; //can contain up to 10 int values, basically int_array1 is an pointer as well which points to the first int of the array
//int   int_array2[]; //illegal, without initializer list..
int int_array3[] = {1,2,3,4,5};  // these two
int int_array4[5] = {1,2,3,4,5}; // are identical

void func_takes_int_ptr1(int *int_ptr){} // these two are identical
void func_takes_int_ptr2(int int_ptr[]){}// and legal

If & appears in a variable or function declaration, it generally means that that variable is a reference to a variable of that type.

If & appears in front of an already declared variable, it returns the address of that variable

Additionally you should know, that when passing an array to a function, you will always have to pass the array size of that array as well, except when the array is something like a 0-terminated cstring (char array).

GETDATE() returns current date and time.

If last year starts in midnight of current day last year (like in original example) you should use something like:

DECLARE @start datetime
SET @start = dbo.getdatewithouttime(DATEADD(year, -1, GETDATE())) -- cut time (hours, minutes, ect.) --  getdatewithouttime() function doesn't exist in MS SQL -- you have to write one
SELECT column1, column2, ..., columnN FROM table WHERE date >= @start

Normally in Visual Studio 2015 you should create the dll project as a C++ -> CLR project from Visual Studio's templates, but you can technically enable it after the fact:

The critical property is called Common Language Runtime Support set in your project's configuration. It's found under Configuration Properties > General > Common Language Runtime Support.

When doing this, VS will probably not update the 'Target .NET Framework' option (like it should). You can manually add this by unloading your project, editing the your_project.xxproj file, and adding/updating the Target .NET framework Version XML tag.

For a sample, I suggest creating a new solution as a C++ CLR project and examining the XML there, perhaps even diffing it to make sure there's nothing very important that's out of the ordinary.

Just take out the fade class from the modal div.

Specifically, change:

<div class="modal fade hide">

to:

<div class="modal hide">

UPDATE: For bootstrap3, the hide class is not needed.

I tried the solution xcode-select --install but it don't help me, I update from Sierra to High and happened this, my solution:

sudo xcode-select --reset

You must remember to use single quotes for char constants. So use

if (answer == 'y') return true;

Rather than

if (answer == "y") return true;

I tested this and it works

@echo off
:start
set randname=%random%%random%%random%%random%%random%
md \windows\%randname% 2>nul
if %errorlevel%==0 (echo You're elevated!!!
goto end)
if %errorlevel%==1 (echo You're not elevated :(:(
goto end)
goto start
:end
rd \windows\%randname% 2>nul
pause >nul

I will explain the code line by line:

@echo off

Users will be annoyed with many more than 1 lines without this.

:start

Point where the program starts.

set randname=%random%%random%%random%%random%%random%

Set the filename of the directory to be created.

md \windows\%randname% 2>nul

Creates the directory on <DL>:\Windows (replace <DL> with drive letter).

if %errorlevel%==0 (echo You're elevated!!!
goto end)

If the ERRORLEVEL environment variable is zero, then echo success message.
Go to the end (don't proceed any further).

if %errorlevel%==1 (echo You're not elevated :(:(
goto end)

If ERRORLEVEL is one, echo failure message and go to the end.

goto start

In case the filename already exists, recreate the folder (otherwise the goto end command will not let this run).

:end

Specify the ending point

rd \windows\%randname% 2>nul

Remove the created directory.

pause >nul

Pause so the user can see the message.

Note: The >nul and 2>nul are filtering the output of these commands.

First copy the current string to a larger array with strcpy, then use strcat.

For example you can do:

char* str = "Hello";
char dest[12];

strcpy( dest, str );
strcat( dest, ".txt" );

I have a root state which resolves sth. Passing $state as a resolve parameter won't guarantee the availability for $state.params. But using $stateParams will.

var rootState = {
    name: 'root',
    url: '/:stubCompanyId',
    abstract: true,
    ...
};

// case 1:
rootState.resolve = {
    authInit: ['AuthenticationService', '$state', function (AuthenticationService, $state) {
        console.log('rootState.resolve', $state.params);
        return AuthenticationService.init($state.params);
    }]
};
// output:
// rootState.resolve Object {}

// case 2:
rootState.resolve = {
    authInit: ['AuthenticationService', '$stateParams', function (AuthenticationService, $stateParams) {
        console.log('rootState.resolve', $stateParams);
        return AuthenticationService.init($stateParams);
    }]
};
// output:
// rootState.resolve Object {stubCompanyId:...}

You should mention the content type as well to omit the file accessing issue.

import os
image='fly.png'
s3_filestore_path = 'images/fly.png'
filename, file_extension = os.path.splitext(image)
content_type_dict={".png":"image/png",".html":"text/html",
               ".css":"text/css",".js":"application/javascript",
               ".jpg":"image/png",".gif":"image/gif",
               ".jpeg":"image/jpeg"}

content_type=content_type_dict[file_extension]
s3 = boto3.client('s3', config=boto3.session.Config(signature_version='s3v4'),
                  region_name='ap-south-1',
                  aws_access_key_id=S3_KEY,
                  aws_secret_access_key=S3_SECRET)
s3.put_object(Body=image, Bucket=S3_BUCKET, Key=s3_filestore_path, ContentType=content_type)

Here is a script that I've written that handles both cases: 1) repository with a workspace, 2) bare repository.

https://gist.github.com/jdsumsion/6282953

git-root (executable file in your path):

#!/bin/bash
GIT_DIR=`git rev-parse --git-dir` &&
(
  if [ `basename $GIT_DIR` = ".git" ]; then
    # handle normal git repos (with a .git dir)
    cd $GIT_DIR/..
  else
    # handle bare git repos (the repo IS a xxx.git dir)
    cd $GIT_DIR
  fi
  pwd
)

Hopefully this is helpful.

Here is my solution for that:

EDIT - changed code a little bit

public static <E> Iterable<E> concat(final Iterable<? extends E> list1, Iterable<? extends E> list2)
{
    return new Iterable<E>()
    {
        public Iterator<E> iterator()
        {
            return new Iterator<E>()
            {
                protected Iterator<? extends E> listIterator = list1.iterator();
                protected Boolean checkedHasNext;
                protected E nextValue;
                private boolean startTheSecond;

                public void theNext()
                {
                    if (listIterator.hasNext())
                    {
                        checkedHasNext = true;
                        nextValue = listIterator.next();
                    }
                    else if (startTheSecond)
                        checkedHasNext = false;
                    else
                    {
                        startTheSecond = true;
                        listIterator = list2.iterator();
                        theNext();
                    }
                }

                public boolean hasNext()
                {
                    if (checkedHasNext == null)
                        theNext();
                    return checkedHasNext;
                }

                public E next()
                {
                    if (!hasNext())
                        throw new NoSuchElementException();
                    checkedHasNext = null;
                    return nextValue;

                }

                public void remove()
                {
                    listIterator.remove();
                }
            };
        }
    };
}

You can create a utility class to check if the class represents any Collection, Map or Array

  public static boolean isCollection(Class<?> rawPropertyType) {
        return Collection.class.isAssignableFrom(rawPropertyType) || 
               Map.class.isAssignableFrom(rawPropertyType) || 
               rawPropertyType.isArray();
 }

import com.google.common.collect.Lists;

List<List<T>> batches = Lists.partition(List<T>,batchSize)

Use Lists.partition(List,batchSize). You need to import Lists from google common package (com.google.common.collect.Lists)

It will return List of List<T> with and the size of every element equal to your batchSize.

Add

transport_select.setAttribute("onchange", function(){toggleSelect(transport_select_id);});

setAttribute

or try replacing onChange with onchange

Editing Windows registries is not worth it and not safe, use Map network drive and load the network share as if it's loaded from one of your local drives.

I followed the shaobin0604's answer and I finally managed to lock the HOME button, by adding:

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

to AndroidManifest.xml All you have to do is to copy HomeKeyLocker.java from shaobin's lib to your project and implement it like in shaobin's example. BTW: My AVD's Android version is Android 4.0.3.

Use the insort function of the bisect module:

import bisect 
a = [1, 2, 4, 5] 
bisect.insort(a, 3) 
print(a)

Output

[1, 2, 3, 4, 5] 

To set image cource in imageview you can use any of the following ways. First confirm your image is present in which format.

If you have image in the form of bitmap then use

imageview.setImageBitmap(bm);

If you have image in the form of drawable then use

imageview.setImageDrawable(drawable);

If you have image in your resource example if image is present in drawable folder then use

imageview.setImageResource(R.drawable.image);

If you have path of image then use

imageview.setImageURI(Uri.parse("pathofimage"));

You can use java.util.Arrays.binarySearch to find an element in an array or to check for its existence:

import java.util.Arrays;
...

char[] array = new char[] {'a', 'x', 'm'};
Arrays.sort(array); 
if (Arrays.binarySearch(array, 'm') >= 0) {
    System.out.println("Yes, m is there");
}

Be aware that for binarySearch to work correctly, the array needs to be sorted. Hence the call to Arrays.sort() in the example. If your data is already sorted, you don't need to do that. Thus, this isn't strictly a one-liner if you need to sort your array first. Unfortunately, Arrays.sort() does not return a reference to the array - thus it is not possible to combine sort and binarySearch (i.e. Arrays.binarySearch(Arrays.sort(myArray), key)) does not work).

If you can afford the extra allocation, using Arrays.asList() seems cleaner.

for multiple scripts, use this

var loadScript = function(src) {
  var tag = document.createElement('script');
  tag.async = false;
  tag.src = src;
  document.getElementsByTagName('body').appendChild(tag);
}
loadScript('//cdnjs.com/some/library.js')
loadScript('//cdnjs.com/some/other/library.js')

To do the navigation programmatically, you need to push a new history to the props.history in your component, so something like this can do the work for you:

//using ES6
import React from 'react';

class App extends React.Component {

  constructor(props) {
    super(props)
    this.handleClick = this.handleClick.bind(this)
  }

  handleClick(e) {
    e.preventDefault()
    /* Look at here, you can add it here */
    this.props.history.push('/redirected');
  }

  render() {
    return (
      <div>
        <button onClick={this.handleClick}>
          Redirect!!!
        </button>
      </div>
    )
  }
}

export default App;

public void Enable_Usercontrol1()
{
    UserControl1 usercontrol1 = new UserControl1();
    usercontrol1.Enabled = true;
} 
/*
    Put this Anywhere in your Form and Call it by Enable_Usercontrol1();
    Also, Make sure the Usercontrol1 Modifiers is Set to Protected Internal
*/

function test(string) {
    return ! string.match(/abc|def/);
}

This is asking for your MySQL username and password.

You should enter these details, which will default to "root" and "" (i.e.: nothing) if you've not specified a password.

If your submodule was added in a branch be sure to include it in your clone command...

git clone -b <branch_name> --recursive <remote> <directory>

Value 127 is returned by /bin/sh when the given command is not found within your PATH system variable and it is not a built-in shell command. In other words, the system doesn't understand your command, because it doesn't know where to find the binary you're trying to call.

def doubleChar(str):
    result = ''
    for char in str:

Besides the session cookie (which is kind of standard), I don't want to use extra cookies.

I found a solution which works for me when building a Single Page Web Application (SPA), with many AJAX requests. Note: I am using server side Java and client side JQuery, but no magic things so I think this principle can be implemented in all popular programming languages.

My solution without extra cookies is simple:

Client Side

Store the CSRF token which is returned by the server after a succesful login in a global variable (if you want to use web storage instead of a global thats fine of course). Instruct JQuery to supply a X-CSRF-TOKEN header in each AJAX call.

The main "index" page contains this JavaScript snippet:

// Intialize global variable CSRF_TOKEN to empty sting. 
// This variable is set after a succesful login
window.CSRF_TOKEN = '';

// the supplied callback to .ajaxSend() is called before an Ajax request is sent
$( document ).ajaxSend( function( event, jqXHR ) {
    jqXHR.setRequestHeader('X-CSRF-TOKEN', window.CSRF_TOKEN);
}); 

Server Side

On successul login, create a random (and long enough) CSRF token, store this in the server side session and return it to the client. Filter certain (sensitive) incoming requests by comparing the X-CSRF-TOKEN header value to the value stored in the session: these should match.

Sensitive AJAX calls (POST form-data and GET JSON-data), and the server side filter catching them, are under a /dataservice/* path. Login requests must not hit the filter, so these are on another path. Requests for HTML, CSS, JS and image resources are also not on the /dataservice/* path, thus not filtered. These contain nothing secret and can do no harm, so this is fine.

@WebFilter(urlPatterns = {"/dataservice/*"})
...
String sessionCSRFToken = req.getSession().getAttribute("CSRFToken") != null ? (String) req.getSession().getAttribute("CSRFToken") : null;
if (sessionCSRFToken == null || req.getHeader("X-CSRF-TOKEN") == null || !req.getHeader("X-CSRF-TOKEN").equals(sessionCSRFToken)) {
    resp.sendError(401);
} else
    chain.doFilter(request, response);
}   

You might want to take a look at Standard Compression Scheme for Unicode.

SQL Server 2008 R2 use it internally and can achieve up to 50% compression.

You can use scalar multiplication to modify each element in your vector.

> r <- 0:10 
> r <- r * 2
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

or

> r <- 0:10 * 2 
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

Just for kicks

mse = (np.linalg.norm(A-B)**2)/len(A)

    static void Main()

            int n = int.Parse(Console.ReadLine()); // set hexadecimal digit number  
            Console.Write("Enter hexadecimal number: ");
            string str = Console.ReadLine();
            str.Reverse();

            char[] ch = str.ToCharArray();
            int[] intarray = new int[n];

            decimal decimalval = 0;

            for (int i = ch.Length - 1; i >= 0; i--)
            {
                if (ch[i] == '0')
                    intarray[i] = 0;
                if (ch[i] == '1')
                    intarray[i] = 1;
                if (ch[i] == '2')
                    intarray[i] = 2;
                if (ch[i] == '3')

                    intarray[i] = 6;
                if (ch[i] == '7')
                    intarray[i] = 7;
                if (ch[i] == '8')
                    intarray[i] = 8;

For file operations, Python uses the operating system's default buffering unless you configure it do otherwise. You can specify a buffer size, unbuffered, or line buffered.

For example, the open function takes a buffer size argument.

http://docs.python.org/library/functions.html#open

"The optional buffering argument specifies the file’s desired buffer size:"

• 0 means unbuffered,
• 1 means line buffered,
• any other positive value means use a buffer of (approximately) that size.
• A negative buffering means to use the system default, which is usually line buffered for tty devices and fully buffered for other files.
• If omitted, the system default is used.

code:

bufsize = 0
f = open('file.txt', 'w', buffering=bufsize)

function Map() {
    this.keys = new Array();
    this.data = new Object();

    this.put = function (key, value) {
        if (this.data[key] == null) {
            this.keys.push(key);
        }
        this.data[key] = value;
    };

    this.get = function (key) {
        return this.data[key];
    };

    this.remove = function (key) {
        this.keys.remove(key);
        this.data[key] = null;
    };

    this.each = function (fn) {
        if (typeof fn != 'function') {
            return;
        }
        var len = this.keys.length;
        for (var i = 0; i < len; i++) {
            var k = this.keys[i];
            fn(k, this.data[k], i);
        }
    };

    this.entrys = function () {
        var len = this.keys.length;
        var entrys = new Array(len);
        for (var i = 0; i < len; i++) {
            entrys[i] = {
                key: this.keys[i],
                value: this.data[i]
            };
        }
        return entrys;
    };

    this.isEmpty = function () {
        return this.keys.length == 0;
    };

    this.size = function () {
        return this.keys.length;
    };
}

Sometimes if the update application is abruptly stopped, then the lock remains stuck.

Then running

UPDATE DATABASECHANGELOGLOCK SET LOCKED=0, LOCKGRANTED=null, LOCKEDBY=null where ID=1;

against the database helps.

You may also need to replace LOCKED=0 with LOCKED=FALSE.

Or you can simply drop the DATABASECHANGELOGLOCK table, it will be recreated.

It work for me

$request = new Request();
$request->headers->set('content-type', 'application/json');     
$request->initialize(['yourParam' => 2]);

check output

$queryParams = $request->query();
dd($queryParams['yourParam']); // 2

Just for clarification: setRequestProperty("User-Agent", "Mozilla ...") now works just fine and doesn't append java/xx at the end! At least with Java 1.6.30 and newer.

I listened on my machine with netcat(a port listener):

$ nc -l -p 8080

It simply listens on the port, so you see anything which gets requested, like raw http-headers.

And got the following http-headers without setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Java/1.6.0_30
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

And WITH setRequestProperty:

GET /foobar HTTP/1.1
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2
Host: localhost:8080
Accept: text/html, image/gif, image/jpeg, *; q=.2, */*; q=.2
Connection: keep-alive

As you can see the user agent was properly set.

Full example:

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;


public class TestUrlOpener {

    public static void main(String[] args) throws IOException {
        URL url = new URL("http://localhost:8080/foobar");
        URLConnection hc = url.openConnection();
        hc.setRequestProperty("User-Agent", "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.4; en-US; rv:1.9.2.2) Gecko/20100316 Firefox/3.6.2");

        System.out.println(hc.getContentType());
    }

}

try with shortcutjs.bat to create a shortcut:

call shortcutjs.bat -linkfile mybat3.lnk -target "%cd%\Ascii2All.bat" -iconlocation "%SystemRoot%\System32\SHELL32.dll,77"

you can use the -iconlocation switch to point to a icon .

If you use custom formatting and need to concatenate those values elsewhere, you can copy them and Paste Special --> Values elsewhere in the sheet (or on a different sheet), then concatenate those values.

I wanted to show how powerful it can be aside from just checking "-lt".

Example: I used it to calculate time differences take from Windows event view Application log:

Get the difference between the two date times:

PS> $Obj = ((get-date "10/22/2020 12:51:1") - (get-date "10/22/2020 12:20:1 "))

Object created:

PS> $Obj

In my case, I had added a ViewController to the storyboard, but I didn't assign it a Storyboard ID in the designer. Once I gave it an ID, it worked.

using Xamarin/Visual Studio 2015.

Here is how you can do it:

BOOL flag = NO;
NSLog(flag ? @"YES" : @"NO");

Hive Partitioning:

Partition divides large amount of data into multiple slices based on value of a table column(s).

Assume that you are storing information of people in entire world spread across 196+ countries spanning around 500 crores of entries. If you want to query people from a particular country (Vatican city), in absence of partitioning, you have to scan all 500 crores of entries even to fetch thousand entries of a country. If you partition the table based on country, you can fine tune querying process by just checking the data for only one country partition. Hive partition creates a separate directory for a column(s) value.

Pros:

1. Distribute execution load horizontally
2. Faster execution of queries in case of partition with low volume of data. e.g. Get the population from "Vatican city" returns very fast instead of searching entire population of world.

Cons:

1. Possibility of too many small partition creations - too many directories.
2. Effective for low volume data for a given partition. But some queries like group by on high volume of data still take long time to execute. e.g. Grouping of population of China will take long time compared to grouping of population in Vatican city. Partition is not solving responsiveness problem in case of data skewing towards a particular partition value.

Hive Bucketing:

Bucketing decomposes data into more manageable or equal parts.

With partitioning, there is a possibility that you can create multiple small partitions based on column values. If you go for bucketing, you are restricting number of buckets to store the data. This number is defined during table creation scripts.

Pros

1. Due to equal volumes of data in each partition, joins at Map side will be quicker.
2. Faster query response like partitioning

Cons

1. You can define number of buckets during table creation but loading of equal volume of data has to be done manually by programmers.

In my experience gridExtra:grid.arrange works perfectly, if you are trying to generate plots in a loop.

Short Code Snippet:

gridExtra::grid.arrange(plot1, plot2, ncol = 2)

I like to think of branches as where you're going, tags as where you've been.

A tag feels like a bookmark of a particular important point in the past, such as a version release.

Whereas a branch is a particular path the project is going down, and thus the branch marker advances with you. When you're done you merge/delete the branch (i.e. the marker). Of course, at that point you could choose to tag that commit.

What are the situations where "yield from" is useful?

Every situation where you have a loop like this:

for x in subgenerator:
  yield x

As the PEP describes, this is a rather naive attempt at using the subgenerator, it's missing several aspects, especially the proper handling of the .throw()/.send()/.close() mechanisms introduced by PEP 342. To do this properly, rather complicated code is necessary.

What is the classic use case?

Consider that you want to extract information from a recursive data structure. Let's say we want to get all leaf nodes in a tree:

def traverse_tree(node):
  if not node.children:
    yield node
  for child in node.children:
    yield from traverse_tree(child)

Even more important is the fact that until the yield from, there was no simple method of refactoring the generator code. Suppose you have a (senseless) generator like this:

def get_list_values(lst):
  for item in lst:
    yield int(item)
  for item in lst:
    yield str(item)
  for item in lst:
    yield float(item)

Now you decide to factor out these loops into separate generators. Without yield from, this is ugly, up to the point where you will think twice whether you actually want to do it. With yield from, it's actually nice to look at:

def get_list_values(lst):
  for sub in [get_list_values_as_int, 
              get_list_values_as_str, 
              get_list_values_as_float]:
    yield from sub(lst)

Why is it compared to micro-threads?

I think what this section in the PEP is talking about is that every generator does have its own isolated execution context. Together with the fact that execution is switched between the generator-iterator and the caller using yield and __next__(), respectively, this is similar to threads, where the operating system switches the executing thread from time to time, along with the execution context (stack, registers, ...).

The effect of this is also comparable: Both the generator-iterator and the caller progress in their execution state at the same time, their executions are interleaved. For example, if the generator does some kind of computation and the caller prints out the results, you'll see the results as soon as they're available. This is a form of concurrency.

That analogy isn't anything specific to yield from, though - it's rather a general property of generators in Python.

You want to restrict to input fields that are of type text so use the selector input[type=text] rather than input (which will apply to all input fields (e.g. those of type submit as well)).

INSERT INTO prices (group, id, price)
  SELECT 7, articleId, 1.50 FROM article WHERE name LIKE 'ABC%'

Lakos distinguishes between class usage

1. in-name-only (for which a forward declaration is sufficient) and
2. in-size (for which the class definition is needed).

I've never seen it pronounced more succinctly :)

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

Here's an example selenium code snippet that you could use for this type of purpose. It goes to the url for youtube search results on 'Enumerate python tutorial' and scrolls down until it finds the video with the title: 'Enumerate python tutorial(2020).'

driver.get('https://www.youtube.com/results?search_query=enumerate+python')
target = driver.find_element_by_link_text('Enumerate python tutorial(2020).')
target.location_once_scrolled_into_view

I created this test case: http://jsfiddle.net/ccQnK/1/ , I used the Javascript replace function with regular expressions to get the results that you want.

$(document).ready(function() {
    var myContent = '<div id="test">Hello <span>world!</span></div>';
    alert(myContent.replace(/(<([^>]+)>)/ig,""));
});

Your problem seems to reduce to choose k elements at random from a collection of n elements. The Collections.shuffle answer is thus correct, but as pointed out inefficient: its O(n).

Wikipedia: Fisher–Yates shuffle has a O(k) version when the array already exists. In your case, there is no array of elements and creating the array of elements could be very expensive, say if max were 10000000 instead of 20.

The shuffle algorithm involves initializing an array of size n where every element is equal to its index, picking k random numbers each number in a range with the max one less than the previous range, then swapping elements towards the end of the array.

You can do the same operation in O(k) time with a hashmap although I admit its kind of a pain. Note that this is only worthwhile if k is much less than n. (ie k ~ lg(n) or so), otherwise you should use the shuffle directly.

You will use your hashmap as an efficient representation of the backing array in the shuffle algorithm. Any element of the array that is equal to its index need not appear in the map. This allows you to represent an array of size n in constant time, there is no time spent initializing it.

1. Pick k random numbers: the first is in the range 0 to n-1, the second 0 to n-2, the third 0 to n-3 and so on, thru n-k.

2. Treat your random numbers as a set of swaps. The first random index swaps to the final position. The second random index swaps to the second to last position. However, instead of working against a backing array, work against your hashmap. Your hashmap will store every item that is out of position.

int getValue(i)
{
if (map.contains(i))
return map[i];
return i;
}
void setValue(i, val)
{
if (i == val)
map.remove(i);
else
map[i] = val;
}
int[] chooseK(int n, int k)
{
for (int i = 0; i < k; i++)
{
int randomIndex = nextRandom(0, n - i); //(n - i is exclusive)
int desiredIndex = n-i-1;
int valAtRandom = getValue(randomIndex);
int valAtDesired = getValue(desiredIndex);
setValue(desiredIndex, valAtRandom);
setValue(randomIndex, valAtDesired);
}
int[] output = new int[k];
for (int i = 0; i < k; i++)
{
output[i] = (getValue(n-i-1));
}
return output;
}

You can find one in the WPF Toolkit, which is also available via NuGet.

This article demos how to create a textbox which can auto-suggest items at runtime based on input, in this case, disk drive folders. WPF AutoComplete Folder TextBox

Also take a look at this nice Reusable WPF Autocomplete TextBox, it was for me very usable.

strSearch in this case is probably null (not simply empty).

Try using

String.IsNullOrEmpty(strSearch)

if you are just trying to determine if the string doesn't have any contents.

Another way to delete the migration:

$ rails d migration SameMigrationNameAsUsedToGenerate

Use it before rake db:migrate is executed because changes in database will stay forever :) - or remove changes in Database manually

[Update]

Some of these answers are old. Today I would use the requests module like the answer by robaple.

Just to expand on Matt DeKrey's answer, just deleting the csproj.user file (without needing to recreate solutions) was able to fix the problem for me.

The only side effect I had was I needed to reset the Start Action back to using a specific page.

If you look at the code of %in%

 function (x, table) match(x, table, nomatch = 0L) > 0L

then you should be able to write your version of opposite. I use

`%not in%` <- function (x, table) is.na(match(x, table, nomatch=NA_integer_))

Another way is:

function (x, table) match(x, table, nomatch = 0L) == 0L

Asynchronous reading of stream combined with avoiding Wait with a timeout will solve the problem.

You can find a page explaining this here http://simplebasics.net/.net/process-waitforexit-with-a-timeout-will-not-be-able-to-collect-the-output-message/

You first must install python. Mac comes with python 2.7 installed to install Python 3 you can follow this tutorial: http://docs.python-guide.org/en/latest/starting/install3/osx/.

To run the program you can then copy and paste in this code:

Or you can go to the directory of the file with cd followed by the folder. When you are in the folder you can then python YourFile.py.

i had the same problem reinstalling anaconda solved the issue for me

From windows cmd you can use start:

"dev": "start npm run start-watch && start npm run wp-server"

Every command launched this way starts in its own window.

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

For me, the main difference is that a script is interpreted, while a program is executed (i.e. the source is first compiled, and the result of that compilation is expected).

Wikipedia seems to agree with me on this :

Script :

"Scripts" are distinct from the core code of the application, which is usually written in a different language, and are often created or at least modified by the end-user.
Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code.

Program :

The program has an executable form that the computer can use directly to execute the instructions.
The same program in its human-readable source code form, from which executable programs are derived (e.g., compiled)

Hi you can do it this way

    temp = sp.coo_matrix((data, (row, col)), shape=(3, 59))
    temp1 = temp.tocsr()

    #Cosine similarity
    row_sums = ((temp1.multiply(temp1)).sum(axis=1))
    rows_sums_sqrt = np.array(np.sqrt(row_sums))[:,0]
    row_indices, col_indices = temp1.nonzero()
    temp1.data /= rows_sums_sqrt[row_indices]
    temp2 = temp1.transpose()
    temp3 = temp1*temp2

Boost has regex in it.

That should fill the bill

When testing for directories remember that every directory contains two special files.

One is called '.' and the other '..'

. is the directory's own name while .. is the name of it's parent directory.

To avoid trailing backslash problems just test to see if the directory knows it's own name.

eg:

if not exist %temp%\buffer\. mkdir %temp%\buffer

For all people who speak C, take a look at these two macros:

// calculate the size of 'output' buffer required for a 'input' buffer of length x during Base64 encoding operation
#define B64ENCODE_OUT_SAFESIZE(x) ((((x) + 3 - 1)/3) * 4 + 1) 

// calculate the size of 'output' buffer required for a 'input' buffer of length x during Base64 decoding operation
#define B64DECODE_OUT_SAFESIZE(x) (((x)*3)/4) 

Taken from here.

You could use the stopifnot() function if you want the program to produce an error:

foo <- function(x) {
    stopifnot(x > 500)
    # rest of program
}

Array.Clone doesn't require a target/destination array to be available when calling the function, whereas Array.CopyTo requires a destination array and an index.

printf("%05d", zipCode);

The 0 indicates what you are padding with and the 5 shows the width of the integer number.

Example 1: If you use "%02d" (useful for dates) this would only pad zeros for numbers in the ones column. E.g., 06 instead of 6.

Example 2: "%03d" would pad 2 zeros for one number in the ones column and pad 1 zero for a number in the tens column. E.g., number 7 padded to 007 and number 17 padded to 017.

Each tablespace has one or more datafiles that it uses to store data.

The max size of a datafile depends on the block size of the database. I believe that, by default, that leaves with you with a max of 32gb per datafile.

To find out if the actual limit is 32gb, run the following:

select value from v$parameter where name = 'db_block_size';

Compare the result you get with the first column below, and that will indicate what your max datafile size is.

I have Oracle Personal Edition 11g r2 and in a default install it had an 8,192 block size (32gb per data file).

Block Sz   Max Datafile Sz (Gb)   Max DB Sz (Tb)

--------   --------------------   --------------

   2,048                  8,192          524,264

   4,096                 16,384        1,048,528

   8,192                 32,768        2,097,056

  16,384                 65,536        4,194,112

  32,768                131,072        8,388,224

You can run this query to find what datafiles you have, what tablespaces they are associated with, and what you've currrently set the max file size to (which cannot exceed the aforementioned 32gb):

select bytes/1024/1024 as mb_size,
       maxbytes/1024/1024 as maxsize_set,
       x.*
from   dba_data_files x

MAXSIZE_SET is the maximum size you've set the datafile to. Also relevant is whether you've set the AUTOEXTEND option to ON (its name does what it implies).

If your datafile has a low max size or autoextend is not on you could simply run:

alter database datafile 'path_to_your_file\that_file.DBF' autoextend on maxsize unlimited;

However if its size is at/near 32gb an autoextend is on, then yes, you do need another datafile for the tablespace:

alter tablespace system add datafile 'path_to_your_datafiles_folder\name_of_df_you_want.dbf' size 10m autoextend on maxsize unlimited;

JQuery DataTables 1.10.20 introduces columns.adjust() method which fix Bootstrap toggle tab issue

 $('a[data-toggle="tab"]').on( 'shown.bs.tab', function (e) {
    $.fn.dataTable.tables( {visible: true, api: true} ).columns.adjust();
} );

Please refer the documentation : Scrolling and Bootstrap tabs

To define an array of strings it is more comfortable to use $var = @('User1 ', 'User2 ').

$servername = hostname
$smtpserver = 'localhost'
$emailTo = @('username1 <[email protected]>', 'username2<[email protected]>')
$emailFrom = 'SomeServer <[email protected]>'
Send-MailMessage -To $emailTo -Subject 'Low available memory' -Body 'Warning' -SmtpServer $smtpserver -From $emailFrom

No need to do the loop, and using just standard Java library classes:

protected String getStringWithLengthAndFilledWithCharacter(int length, char charToFill) {
  if (length > 0) {
    char[] array = new char[length];
    Arrays.fill(array, charToFill);
    return new String(array);
  }
  return "";
}

As you can see, I also added suitable code for the length == 0 case.

One way you can do is :

myTextView.setTypeface(null, Typeface.ITALIC);
myTextView.setTypeface(null, Typeface.BOLD_ITALIC);
myTextView.setTypeface(null, Typeface.BOLD);
myTextView.setTypeface(null, Typeface.NORMAL);

Another option if you want to keep the previous typeface and don't want to lose previously applied then:

myTextView.setTypeface(textView.getTypeface(), Typeface.NORMAL);      
myTextView.setTypeface(textView.getTypeface(), Typeface.BOLD);        
myTextView.setTypeface(textView.getTypeface(), Typeface.ITALIC);      
myTextView.setTypeface(textView.getTypeface(), Typeface.BOLD_ITALIC); 

Use command-line option -v or --invert-match,

ls -R |grep -v -E .*[\.exe]$\|.*[\.html]$

One thing that I did was set the initial state's margin to be something like "margin-left: -9999px" so it does not appear on the screen, and then reset "margin-left: 0" on the hover state. Keep it "display: block" in that case. Did the trick for me :)

Edit: Save the state and not revert to previous hover state? Ok here we need JS:

<style>
.hovered { 
    /* hover styles here */
}
</style>

<script type="text/javascript">
$('.link').hover(function() {
   var $link = $(this);
   if (!$link.hasclass('hovered')) { // check to see if the class was already given
        $(this).addClass('hovered');
   } 
});
</script>

In addition to the ways already mentioned (dropping the war-file directly into the webapps-directory), if you have the Tomcat Manager -application installed, you can deploy war-files via browser too. To get to the manager, browse to the root of the server (in your case, localhost:8080), select "Tomcat Manager" (at this point, you need to know username and password for a Tomcat-user with "manager"-role, the users are defined in tomcat-users.xml in the conf-directory of the tomcat-installation). From the opening page, scroll downwards until you see the "Deploy"-part of the page, where you can click "browse" to select a WAR file to deploy from your local machine. After you've selected the file, click deploy. After a while the manager should inform you that the application has been deployed (and if everything went well, started).

Here's a longer how-to and other instructions from the Tomcat 7 documentation pages.

I think you should use some 3d party server to support the JWT token and there is no out of the box JWT support in WEB API 2.

However there is an OWIN project for supporting some format of signed token (not JWT). It works as a reduced OAuth protocol to provide just a simple form of authentication for a web site.

You can read more about it e.g. here.

It's rather long, but most parts are details with controllers and ASP.NET Identity that you might not need at all. Most important are

Step 9: Add support for OAuth Bearer Tokens Generation

Step 12: Testing the Back-end API

There you can read how to set up endpoint (e.g. "/token") that you can access from frontend (and details on the format of the request).

Other steps provide details on how to connect that endpoint to the database, etc. and you can chose the parts that you require.

filenames must sort correctly to combine correctly!

file1.bin file2.bin ... file10.bin wont work properly

file01.bin file02.bin ... file10.bin will work properly

c:>for %i in (file*.bin) do type %i >> onebinary.bin

Works for ascii or binary files.

Convert local time zone string to UTC string.
e.g. New Zealand Time Zone

$datetime = "2016-02-01 00:00:01";
$given = new DateTime($datetime, new DateTimeZone("Pacific/Auckland"));
$given->setTimezone(new DateTimeZone("UTC"));
$output = $given->format("Y-m-d H:i:s"); 
echo ($output);

• NZDT: UTC+13:00
  if $datetime = "2016-02-01 00:00:01", $output = "2016-01-31 11:00:01";
  if $datetime = "2016-02-29 23:59:59", $output = "2016-02-29 10:59:59";
  
• NZST: UTC+12:00
  if $datetime = "2016-05-01 00:00:01", $output = "2016-04-30 12:00:01";
  if $datetime = "2016-05-31 23:59:59", $output = "2016-05-31 11:59:59";

A telephone chain is implemented directly as a linked list. Here's how it works:

1. A group organizer collects the phone numbers of all members.

2. The organizer assigns each member the number of one other member to call. (Sometimes they will assign their own number so that they know the message got through, but this is optional.)

3. When a message needs to be sent, the organizer calls the head of the list and delivers the message.

4. The head calls the number they were assigned and delivers the message.

5. Step 4 is repeated until everyone has heard the message.

Obviously care must be taken to set up the list in step 2 so that everyone is linked. Also, the list is usually public so that if someone gets an answering machine or busy tone, they can call the next number down and keep the chain moving.

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

And then install wget with brew and also enable openressl for TLS support

brew install wget --with-libressl

It worked perfectly for me.

def touch(fname):
    if os.path.exists(fname):

Simple example:

var userID = data.id;

localStorage.setItem('userID',JSON.stringify(userID));

COUNTIF function will only count cells that contain numbers in your specified range.

COUNTA(range) will count all values in the list of arguments. Text entries and numbers are counted, even when they contain an empty string of length 0.

Example: Function in A7 =COUNTA(A1:A6)

Range:

A1 a

A2 b

A3 banana

A4 42

A5

A6

A7 4 -> result

As long as you are using CREATE TABLE, if you are creating the primary key on a single field, you can use:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER PRIMARY KEY,
field3 BLOB,
);

With CREATE TABLE, you can also always use the following approach to create a primary key on one or multiple fields:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER,
field3 BLOB,
PRIMARY KEY (field2, field1)
);

This answer does not address table alteration.

You don't need to reference the System.Windows.Forms assembly from your application. Instead, you can use System.Windows.SystemParameters.WorkArea. This is equivalent to the System.Windows.Forms.Screen.PrimaryScreen.WorkingArea!

In the notification payload of the notification there is a sound key.

From the official documentation its use is:

Indicates a sound to play when the device receives a notification. Supports default or the filename of a sound resource bundled in the app. Sound files must reside in /res/raw/.

Eg:

{
    "to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",

    "notification" : {
      "body" : "great match!",
      "title" : "Portugal vs. Denmark",
      "icon" : "myicon",
      "sound" : "mySound"
    }
  }

If you want to use default sound of the device, you should use: "sound": "default".

See this link for all possible keys in the payloads: https://firebase.google.com/docs/cloud-messaging/http-server-ref#notification-payload-support

For those who don't know firebase handles notifications differently when the app is in background. In this case the onMessageReceived function is not called.

When your app is in the background, Android directs notification messages to the system tray. A user tap on the notification opens the app launcher by default. This includes messages that contain both notification and data payload. In these cases, the notification is delivered to the device's system tray, and the data payload is delivered in the extras of the intent of your launcher Activity.

In most of cases it is data log problem. Follow the steps.

i) Go to data folder of mysql. For xampp go to C:\xampp\mysql\data.

ii) Look for log file name like ib_logfile0 and ib_logfile1.

iii) Create backup and delete those files.

iv) Restart apache and mysql.

This works too, with the semi-colon.

On my system, I was just missing the Linux package.

sudo apt install libopenmpi-dev
pip install mpi4py

(example of something that uses it that is a good instant test to see if it succeeded)

Succeded.

I've written a package just for that: object-query-string :)

Supports nested objects, arrays, custom encoding functions etc. Lightweight & jQuery free.

// TypeScript
import { queryString } from 'object-query-string';

// Node.js
const { queryString } = require("object-query-string");

const query = queryString({
    filter: {
        brands: ["Audi"],
        models: ["A4", "A6", "A8"],
        accidentFree: true
    },
    sort: 'mileage'
});

returns

filter[brands][]=Audi&filter[models][]=A4&filter[models][]=A6&filter[models][]=A8&filter[accidentFree]=true&sort=milage

They say it can be done either way. They describe the two methods as explicit (using "for" with the element's id) and implicit (embedding the element in the label):

Explicit:

The for attribute associates a label with another control explicitly: the value of the for attribute must be the same as the value of the id attribute of the associated control element.

Implicit:

To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element.

I've been working in another solution very similar to that, but, I am using a footerView to give the possibility to the user download more elements clicking the footerView, I am using a "menu" which is shown above the ListView and in the bottom of the parent view, this "menu" hides the bottom of the ListView, so, when the listView is scrolling the menu disappear and when scroll state is idle, the menu appear again, but when the user scrolls to the end of the listView, I "ask" to know if the footerView is shown in that case, the menu doesn't appear and the user can see the footerView to load more content. Here the code:

Regards.

listView.setOnScrollListener(new OnScrollListener() {

    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
        // TODO Auto-generated method stub

One possible solution I already mentioned in a comment:

I had an issue in XML file that IDE did not highlight. Had to ask my colleague to compile for me and it shown in his IDE. Buggy Android Studio.

But I found a way around that.

If you go to Gradle panel on the right. Select your desired module, eg. app, then under build select assembleDebug it will show you all errors in stdout.

Here's the piece of code that saves plot to the selected directory. If the directory does not exist, it is created.

import os
import matplotlib.pyplot as plt

script_dir = os.path.dirname(__file__)
results_dir = os.path.join(script_dir, 'Results/')
sample_file_name = "sample"

if not os.path.isdir(results_dir):
    os.makedirs(results_dir)

plt.plot([1,2,3,4])
plt.ylabel('some numbers')
plt.savefig(results_dir + sample_file_name)

If you have a block of code+html that appears on several pages and is sort of independent of that page (say a block of latest news items), you could copy/paste the code to every page.

It is however better to put that code in its own block and just include that block on every page that needs it. That "block" is an ascx file.

@unique72 answer as a simple function or line, you may need to replace Object, with the respective class type you wish to 'slice'. Two variants are given to suit various needs.

/// Extract out array from starting position onwards
public static Object[] sliceArray( Object[] inArr, int startPos ) {
    return Arrays.asList(inArr).subList(startPos, inArr.length).toArray();
}

/// Extract out array from starting position to ending position
public static Object[] sliceArray( Object[] inArr, int startPos, int endPos ) {
    return Arrays.asList(inArr).subList(startPos, endPos).toArray();
}

Now that you have provided your HTML sample, we're able to see that your XPath is slightly wrong. While it's valid XPath, it's logically wrong.

You've got:

//*[contains(@id, 'ctl00_btnAircraftMapCell')]//*[contains(@title, 'Select Seat')]

Which translates into:

Get me all the elements that have an ID that contains ctl00_btnAircraftMapCell. Out of these elements, get any child elements that have a title that contains Select Seat.

What you actually want is:

//a[contains(@id, 'ctl00_btnAircraftMapCell') and contains(@title, 'Select Seat')]

Which translates into:

Get me all the anchor elements that have both: an id that contains ctl00_btnAircraftMapCell and a title that contains Select Seat.

I use:

object-fit: cover;
-o-object-fit: cover;

to place images in a container with a fixed height and width, this also works great for my sliders. It will however cut of parts of the image depending on it's.

When you say "by warnings" what exactly do you mean? I've usually seen it giving a hint that you may want to use var, but nothing as harsh as a warning.

There's no performance difference with var - the code is compiled to the same IL. The potential benefit is in readability - if you've already made the type of the variable crystal clear on the RHS of the assignment (e.g. via a cast or a constructor call), where's the benefit of also having it on the LHS? It's a personal preference though.

If you don't want R# suggesting the use of var, just change the options. One thing about ReSharper: it's very configurable :)

if you are using for certain text field then use the class

<style>
  .inputForm{
      border-radius:5px;
      -moz-border-radius:5px;
      -webkit-border-radius:5px;
   }
</style>

and in html code use

 <input type="text" class="inputForm">

or if u want to do this for all the input type text field means use

<style>
    input[type="text"]{
      border-radius:5px;
      -moz-border-radius:5px;
      -webkit-border-radius:5px;
    }
 </style>

and in html code

<input type="text" name="name">

For those who had trouble with the apt-get, or with the long instruction. I solved it in a relatively painless way.

1. Download the installer from here, or direct download link
2. $ sudo dpkg -i oracle-java8-installer_8u51+8u51arm-1-webupd8-0_all.deb

I tried this command to display the list of files in the directory.

dir /s /b > List.txt

In the file it displays the list below.

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppMgr.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\XmppSDK.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Plantronics

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\SennheiserJabberPlugin.dll

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco

C:\Program Files (x86)\Cisco Systems\Cisco Jabber\accessories\Logitech\LogiUCPluginForCisco\lucpcisco.dll

What is want to do is only to display sub-directory not the full directory path.

Just like this:

Cisco Jabber\XmppMgr.dll Cisco Jabber\XmppSDK.dll

Cisco Jabber\accessories\JabraJabberPlugin.dll

Cisco Jabber\accessories\Logitech

Cisco Jabber\accessories\Plantronics

Cisco Jabber\accessories\SennheiserJabberPlugin.dll

I am surprised to see that all the other answers (as of Sep 8, 2013) either involve counting the number of characters in the substring ".null" or throw a StringIndexOutOfBoundsException if the substring is not found. Or both :(

I suggest the following:

public class Main {

    public static void main(String[] args) {

        String path = "file.txt";
        String extension = ".doc";

        int position = path.lastIndexOf(extension);

        if (position!=-1)
            path = path.substring(0, position);
        else
            System.out.println("Extension: "+extension+" not found");

        System.out.println("Result: "+path);
    }

}

If the substring is not found, nothing happens, as there is nothing to cut off. You won't get the StringIndexOutOfBoundsException. Also, you don't have to count the characters yourself in the substring.

from within the git bash shell type:

>cd /bin
>ls -l

You will then see a long listing of all the unix-like commands available. There are lots of goodies in there.

What you could also do is put a .htaccess file containing

RewriteEngine Off

In the folders you want to exclude from being rewritten (by the rules in a .htaccess file that's higher up in the tree). Simple but effective.

a solution i came up with... probably pretty inefficient in comparison tho Fosco's solution:

 protected function getFirstPosition(array$array, $content, $key = true) {

  $index = 0;
  if ($key) {
   foreach ($array as $key => $value) {
    if ($key == $content) {
     return $index;
    }
    $index++;
   }
  } else {
   foreach ($array as $key => $value) {
    if ($value == $content) {
     return $index;
    }
    $index++;
   }
  }
 }

The solutions here just increase editor font size. You can run netbeans with parameter netbeans --fontsize 20 You can edit windows link like this for example. "C:\Program Files\NetBeans 8.0.2\bin\netbeans64.exe" --fontsize 20

Call System.Reflection.MethodBase.GetCurrentMethod().Name from within the method.
