I know this is old. But it helped me a bit. I encountered the same problem in Xamarin.Forms application. My emulator was unable a connect to a public api.

I fixed the problem by starting the emulator with factory defaults in Android Device manager.

i had same issue i resolve this use under

go to gmail.com

Best to import x1 and x2 explicitly:

from file1 import x1, x2

This allows you to avoid unnecessary namespace conflicts with variables and functions from file1 while working in file2.

But if you really want, you can import all the variables:

from file1 import * 

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

You can use setTimeout or setInterval.

The difference is - setTimeout triggers your function only once, and then you must set it again. setInterval keeps triggering expression again and again, unless you tell it to stop

At first sight, yield return is a .NET sugar to return an IEnumerable.

Without yield, all the items of the collection are created at once:

class SomeData
{
    public SomeData() { }

    static public IEnumerable<SomeData> CreateSomeDatas()
    {
        return new List<SomeData> {
            new SomeData(), 
            new SomeData(), 
            new SomeData()
        };
    }
}

Same code using yield, it returns item by item:

class SomeData
{
    public SomeData() { }

    static public IEnumerable<SomeData> CreateSomeDatas()
    {
        yield return new SomeData();
        yield return new SomeData();
        yield return new SomeData();
    }
}

The advantage of using yield is that if the function consuming your data simply needs the first item of the collection, the rest of the items won't be created.

The yield operator allows the creation of items as it is demanded. That's a good reason to use it.

I had to add [AllowAnonymous] to the ActionResult functions in my login page because the user was not authenticated yet.

I had the same problem: The reason of "Received unregistered task of type.." was that celeryd service didn't find and register the tasks on service start (btw their list is visible when you start ./manage.py celeryd --loglevel=info ).

These tasks should be declared in CELERY_IMPORTS = ("tasks", ) in settings file.
If you have a special celery_settings.py file it has to be declared on celeryd service start as --settings=celery_settings.py as digivampire wrote.

I understand what you want. You want to check every data of the array if all of it is empty or at least 1 is not empty

Empty array

Array ( [Tags] => SimpleXMLElement Object ( [0] => ) )

Not an Empty array

Array ( [Tags] => SimpleXMLElement Object ( [0] =>,[1] => "s" ) )

I hope I am right. You can use this function to check every data of an array if at least 1 of them has a value.

/*
 return true if the array is not empty
 return false if it is empty
*/
function is_array_empty($arr){
  if(is_array($arr)){     
      foreach($arr $key => $value){
          if(!empty($value) || $value != NULL || $value != ""){
              return true;
              break;//stop the process we have seen that at least 1 of the array has value so its not empty
          }
      }
      return false;
  }
}

if(is_array_empty($result['Tags'])){
    //array is not empty
}else{
    //array is empty
}

Hope that helps.

I had this same issue, and these 2 commands saved my life. My underlying problem is that I am always messing up with global install and local install. Maybe you are facing a similar issue, and hopefully running these commands will solve your problem too.

ng update --next @angular/cli --force
npm install typescript@latest

You can use below codes for get different parameters of Current URL

alert("document.URL : "+document.URL);
alert("document.location.href : "+document.location.href);
alert("document.location.origin : "+document.location.origin);
alert("document.location.hostname : "+document.location.hostname);
alert("document.location.host : "+document.location.host);
alert("document.location.pathname : "+document.location.pathname);

parentFragmentManager.apply {
    val f = this@MyFragment
    beginTransaction().hide(f).remove(f).commit()
}

If you are in need of the shadows properly to be applied then you have to do the following.

Consider this view, defined with a background drawable:

<TextView
    android:id="@+id/myview"
    ...
    android:elevation="2dp"
    android:background="@drawable/myrect" />

The background drawable is defined as a rectangle with rounded corners:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle">
    <solid android:color="#42000000" />
    <corners android:radius="5dp" />
</shape>

This is the recomended way of appying shadows check this out https://developer.android.com/training/material/shadows-clipping.html#Shadows

SELECT to_char(sysdate + (1/24/60) * 30, 'dd/mm/yy HH24:MI am') from dual;

simply you can use this with various date format....

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

Quick Solution

tarxz() { tar cf - "$1" | xz -4e > "$1".tar.xz ; }
tarxz name_of_directory

(Notice, not name_of_directory/)

Using xz compression options

If you want to use compression options for xz, or if you are using tar on MacOS, you probably want to avoid the tar -cJf syntax.

According to man xz, the way to do this is:

tar cf - filename | xz -4e > filename.tar.xz

Because I liked Wojciech Adam Koszek's format, but not information:

1. c creates a new archive for the specified files.
2. f reads from a directory (best to put this second because -cf != -fc)
3. - outputs to Standard Output
4. | pipes output to the next command
5. xz -4e calls xz with the -4e compression option. (equal to -4 --extreme)
6. > filename.tar.xz directs the tarred and compressed file to filename.tar.xz

where -4e is, use your own compression options. I often use -k to --keep the original file and -9 for really heavy compression. -z to manually set xz to zip, though it defaults to zipping if not otherwise directed.

To uncompress and untar

To echo Rafael van Horn, to uncompress & untar (see note below):

xz -dc filename.tar.xz | tar x

Note: unlike Rafael's answer, use xz -dc instead of catxz. The docs recommend this in case you are using this for scripting. Best to have a habit of using -d or --decompress instead of unxz as well. However, if you must, using those commands from the command line is fine.

You can define a Root ng-App and in this ng-App you can define multiple nd-Controler. Like this

e.printStackTrace equivalent in python

In Java, this does the following (docs):

public void printStackTrace()

Prints this throwable and its backtrace to the standard error stream...

This is used like this:

try
{ 
// code that may raise an error
}
catch (IOException e)
{
// exception handling
e.printStackTrace();
}

In Java, the Standard Error stream is unbuffered so that output arrives immediately.

The same semantics in Python 2 are:

import traceback
import sys
try: # code that may raise an error
    pass 
except IOError as e: # exception handling
    # in Python 2, stderr is also unbuffered
    print >> sys.stderr, traceback.format_exc()
    # in Python 2, you can also from __future__ import print_function
    print(traceback.format_exc(), file=sys.stderr)
    # or as the top answer here demonstrates, use:
    traceback.print_exc()
    # which also uses stderr.

Python 3

In Python 3, we can get the traceback directly from the exception object (which likely behaves better for threaded code). Also, stderr is line-buffered, but the print function gets a flush argument, so this would be immediately printed to stderr:

    print(traceback.format_exception(None, # <- type(e) by docs, but ignored 
                                     e, e.__traceback__),
          file=sys.stderr, flush=True)

Conclusion:

In Python 3, therefore, traceback.print_exc(), although it uses sys.stderr by default, would buffer the output, and you may possibly lose it. So to get as equivalent semantics as possible, in Python 3, use print with flush=True.

This will be the answer:

moment.utc(moment(localdate)).format()

localdate = '2020-01-01 12:00:00'

moment(localdate)
//Moment<2020-01-01T12:00:00+08:00>

moment.utc(moment(localdate)).format()
//2020-01-01T04:00:00Z

This is how I solved clickable and Visible links in a TextView (by code)

private void setAsLink(TextView view, String url){
        Pattern pattern = Pattern.compile(url);
        Linkify.addLinks(view, pattern, "http://");
        view.setText(Html.fromHtml("<a href='http://"+url+"'>http://"+url+"</a>"));
    }

As pointed by others, you were resetting the cipherText in the iteration of the for loop. Placing cipherText before the start of the for loop will solve your problem.

Additionally, there is an alternate approach to solving this problem using Python's Standard library. The Python Standard Library defines a function maketrans() and a method translate that operates on strings.

The function maketrans() creates translation tables that can be used with the translate method to change one set of characters to another more efficiently. (Quoted from The Python Standard Library by Example).

import string

def caesar(plaintext, shift): 

shift %= 26 # Values greater than 26 will wrap around

alphabet_lower = string.ascii_lowercase
alphabet_upper = string.ascii_uppercase

shifted_alphabet_lower = alphabet_lower[shift:] + alphabet_lower[:shift]
shifted_alphabet_upper = alphabet_upper[shift:] + alphabet_upper[:shift]

alphabet = alphabet_lower + alphabet_upper 
shifted_alphabet = shifted_alphabet_lower + shifted_alphabet_upper

table = string.maketrans(alphabet, shifted_alphabet) 

return plaintext.translate(table)

adding HTTP headers using urllib2:

from the docs:

import urllib2
req = urllib2.Request('http://www.example.com/')
req.add_header('Referer', 'http://www.python.org/')
resp = urllib2.urlopen(req)
content = resp.read()

I know this is a bit late but what I did to our application is this. Hope this will help someone tho. But it works for me:

SELECT * FROM `landmarks` WHERE `landmark_name` OR `landmark_description` OR `landmark_address` LIKE '%keyword'
OR `landmark_name` OR `landmark_description` OR `landmark_address` LIKE 'keyword%' 
OR `landmark_name` OR `landmark_description` OR `landmark_address` LIKE '%keyword%'

try this:

$('<img/>').attr('src', 'http://picture.de/image.png').on('load', function() {
   $(this).remove(); // prevent memory leaks as @benweet suggested
   $('body').css('background-image', 'url(http://picture.de/image.png)');
});

this will create new image in memory and use load event to detect when the src is loaded.

This is not possible with native HTML input elements. You can use webshim polyfill, which gives you this option by using this markup.

<input type="date" data-date-inline-picker="true" />

Here is a small demo

There is indeed a Groovier Way.

if(members){
    //Some work
}

does everything if members is a collection. Null check as well as empty check (Empty collections are coerced to false). Hail Groovy Truth. :)

Rob Heiser suggested checking out your java version by using 'java -version'.

That will identify the Java version that will be commonly found and used. Doing dev work, you can often have more than one version installed (I currently have 2 JREs - 6 and 7 - and may soon have 8).

http://www.coderanch.com/t/453224/java/java/java-version-work-setting-path

java -version will look for java.exe in the System32 directory in Windows. That's where a JRE will install it.

I'm assuming that IE either simply looks for java and that automatically starts checking in System32 or it'll use the path and hit whichever java.exe comes first in your path (if you tamper with the path to point to another JRE).

Also from what SLaks said, I would disagree with one thing. There is likely slightly better performance out of 64-it IE in 64-bit environments. So there is some reason for using it.

Like this.

SELECT DISTINCT COL_NAME FROM myTable WHERE COL_NAME iLIKE '%Priceorder%'

In postgresql.

By default, the DirectoryIndex is set to:

DirectoryIndex index.html index.htm default.htm index.php index.php3 index.phtml index.php5 index.shtml mwindex.phtml

Apache will look for each of the above files, in order, and serve the first one it finds when a visitor requests just a directory. If the webserver finds no files in the current directory that match names in the DirectoryIndex directive, then a directory listing will be displayed to the browser, showing all files in the current directory.

The order should be DirectoryIndex index.html index.php // default is index.html

Reference: Here.

Thanks a lot guys for your quick comments.

This is what i will be using now. Posting the function here so that somebody may use it.

public function getDayOfWeek($pTimezone)
{

    $userDateTimeZone = new DateTimeZone($pTimezone);
    $UserDateTime = new DateTime("now", $userDateTimeZone);

    $offsetSeconds = $UserDateTime->getOffset(); 
    //echo $offsetSeconds;

    return gmdate("l", time() + $offsetSeconds);

}

Report if you find any corrections.

this datepicker is an excellent solution. datepickers are a must if you want to avoid code injection.

Try this:

... = new ArrayList<Something>(EnumSet.allOf(Something.class));

as ArrayList has a constructor with Collection<? extends E>. But use this method only if you really want to use EnumSet.

All enums have access to the method values(). It returns an array of all enum values:

... = Arrays.asList(Something.values());

The overhead is NOT due to the encryption. On a modern CPU, the encryption required by SSL is trivial.

The overhead is due to the SSL handshakes, which are lengthy and drastically increase the number of round-trips required for a HTTPS session over a HTTP one.

Measure (using a tool such as Firebug) the page load times while the server is on the end of a simulated high-latency link. Tools exist to simulate a high latency link - for Linux there is "netem". Compare HTTP with HTTPS on the same setup.

The latency can be mitigated to some extent by:

• Ensuring that your server is using HTTP keepalives - this allows the client to reuse SSL sessions, which avoids the need for another handshake
• Reducing the number of requests to as few as possible - by combining resources where possible (e.g. .js include files, CSS) and encouraging client-side caching
• Reduce the number of page loads, e.g. by loading data not required into the page (perhaps in a hidden HTML element) and then showing it using client-script.

I had the same problem, turned out after I have updated my schema, I have forgotten I was calling the model using the old id, which was created by me; I have updated my schema from something like:

patientid: {
           type: String,
            required: true,
            unique: true
          }, 

to

patientid: { type: mongoose.SchemaTypes.ObjectId, ref: "Patient" },

It turned out, since my code is big, I was calling the findOne with the old id, therefore, the problem.

I am posting here just to help somebody else: please, check your code for unknown wrong calls! it may be the problem, and it can save your huge headacles!

If you are looking for a range of columns, you can try this:

df.iloc[7:] = df.iloc[7:].astype(float)

The examples above will convert type to be float, for all the columns begin with the 7th to the end. You of course can use different type or different range.

I think this is useful when you have a big range of columns to convert and a lot of rows. It doesn't make you go over each row by yourself - I believe numpy do it more efficiently.

This is useful only if you know that all the required columns contain numbers only - it will not change "bad values" (like string) to be NaN for you.

Just use

filter_input(INPUT_METHOD_NAME, 'var_name') instead of $_INPUT_METHOD_NAME['var_name'] filter_input_array(INPUT_METHOD_NAME) instead of $_INPUT_METHOD_NAME

e.g

    $host= filter_input(INPUT_SERVER, 'HTTP_HOST');
    echo $host;

instead of

    $host= $_SERVER['HTTP_HOST'];
    echo $host;

And use

    var_dump(filter_input_array(INPUT_SERVER));

instead of

    var_dump($_SERVER);

N.B: Apply to all other Super Global variable

The official Jenkins documentation only mentions single line commands like the following:

// Declarative //

and (see)

pipeline {
    /* insert Declarative Pipeline here */
}

The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:

/* a standalone multiline comment
   spanning two lines */
println "hello" /* a multiline comment starting
                   at the end of a statement */
println 1 /* one */ + 2 /* two */

or

/**
 * such a nice comment
 */

You can use <progress> element in HTML5. See this page for source code and live demo. http://purpledesign.in/blog/super-cool-loading-bar-html5/

here is the progress element...

<progress id="progressbar" value="20" max="100"></progress>

this will have the loading value starting from 20. Of course only the element wont suffice. You need to move it as the script loads. For that we need JQuery. Here is a simple JQuery script that starts the progress from 0 to 100 and does something in defined time slot.

<script>
        $(document).ready(function() {
         if(!Modernizr.meter){
         alert('Sorry your brower does not support HTML5 progress bar');
         } else {
         var progressbar = $('#progressbar'),
         max = progressbar.attr('max'),
         time = (1000/max)*10, 
         value = progressbar.val();
        var loading = function() {
        value += 1;
        addValue = progressbar.val(value);

Hope this will give you a start.

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

Beware of using vars as the target directory name for WORKDIR - doing that appears to result in a "cannot normalize nothing" fatal error. IMO, it's also worth pointing out that WORKDIR behaves in the same way as mkdir -p <path> i.e. all elements of the path are created if they don't exist already.

UPDATE: I encountered the variable related problem (mentioned above) whilst running a multi-stage build - it now appears that using a variable is fine - if it (the variable) is "in scope" e.g. in the following, the 2nd WORKDIR reference fails ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
WORKDIR $varname

whereas, it succeeds in this ...

FROM <some image>
ENV varname varval
WORKDIR $varname

FROM <some other image>
ENV varname varval
WORKDIR $varname

A Trie data structure would work the best, better than DP. Here is the code.

        for i,character in enumerate(value):
            index = ord(character) - ord('a')
            if not root.child[index]:
                root.child[index] = self.getNewNode()
            root = root.child[index]

        root.endWord = True


    def search(self,value):
        root = self.root

        for i,character in enumerate(value):
            index = ord(character) - ord('a')
            if not root.child[index]:
                return False
            root = root.child[index]
        return root.endWord

def main(): 

    # Input keys (use only 'a' through 'z' and lower case) 
    keys = ["the","anaswe"] 
    output = ["Not present in trie", 
            "Present in trie"] 

    # Trie object 
    t = Trie()

Let me know in case of doubts.

For me i install java version 8 and just select the java version in "JDK location":

For me, I always choose non-thread safe version because I always use nginx, or run PHP from the command line.

The non-thread safe version should be used if you install PHP as a CGI binary, command line interface or other environment where only a single thread is used.

A thread-safe version should be used if you install PHP as an Apache module in a worker MPM (multi-processing model) or other environment where multiple PHP threads run concurrently.

Color.parseHexColor("17ee27") did not work for me, instead Color.parseColor("17ee27") worked perfectly.

Arrays, by far, are the most widely used data structures. However, linked lists prove useful in their own unique way where arrays are clumsy - or expensive, to say the least.

Linked lists are useful to implement stacks and queues in situations where their size is subject to vary. Each node in the linked list can be pushed or popped without disturbing the majority of the nodes. Same goes for insertion/deletion of nodes somewhere in the middle. In arrays, however, all the elements have to be shifted, which is an expensive job in terms of execution time.

Binary trees and binary search trees, hash tables, and tries are some of the data structures wherein - at least in C - you need linked lists as a fundamental ingredient for building them up.

However, linked lists should be avoided in situations where it is expected to be able to call any arbitrary element by its index.

Just adding an example that worked fine for me:

$sqldb = [string]($sqldir) + '\bin\MySQLInstanceConfig.exe'
$myarg = '-i ConnectionUsage=DSS Port=3311 ServiceName=MySQL RootPassword= ' + $rootpw
Start-Process $sqldb -ArgumentList $myarg

Using phpMyAdmin you can also set the options to show BLOB content and show complete text.

for (i>0; i--;)

is probably wrong and should be

for (; i>0; i--)

instead. Note where I put the semicolons. The condition goes in the middle, not at the start.

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

Live example

Cast works where the actual instance of the list is an ArrayList. If it is, say, a Vector (which is another extension of List) it will throw a ClassCastException.

The error when changing the definition of your HashMap is due to the elements later being processed, and that process expects a method that is defined only in ArrayList. The exception tells you that it did not found the method it was looking for.

Create a new ArrayList with the contents of the old one.

new ArrayList<String>(myList);

Had a similar problem with a ghost table. Thankfully had an SQL dump from before the failure.

In my case, I had to:

1. Stop mySQL
2. Move ib* files from /var/mysql off to a backup
3. Delete /var/mysql/{dbname}
4. Restart mySQL
5. Recreate empty database
6. Restore dump file

NOTE: Requires dump file.

don't use recursive approach (heap issues) :) use a queue

queue.add(param_dir)
while (queue is not empty){

  directory=  queue.pop
 - get items from current directory
 - if item is file add to a list (final list)
 - if item is directory => queue.push
}

that was easy, enjoy!

You should implement a Custom List View, such that you define a Layout once and draw it for every row in the list view.

Git tags are just pointers to the commit. So you use them the same way as you do HEAD, branch names or commit sha hashes. You can use tags with any git command that accepts commit/revision arguments. You can try it with git rev-parse tagname to display the commit it points to.

In your case you have at least these two alternatives:

1. Reset the current branch to specific tag:

   git reset --hard tagname
   

2. Generate revert commit on top to get you to the state of the tag:

   git revert tag
   

This might introduce some conflicts if you have merge commits though.

In direct opposition to my other answer, this following function is probably safe, even with multi-byte characters.

// replace any non-ascii character with its hex code.
function escape($value) {
    $return = '';
    for($i = 0; $i < strlen($value); ++$i) {
        $char = $value[$i];
        $ord = ord($char);
        if($char !== "'" && $char !== "\"" && $char !== '\\' && $ord >= 32 && $ord <= 126)
            $return .= $char;
        else
            $return .= '\\x' . dechex($ord);
    }
    return $return;
}

Many answers available here, but I missed this simple extension, suitable for Swift 2 and up:

extension Array where Element:Equatable {
    func removeDuplicates() -> [Element] {
        var result = [Element]()

        for value in self {
            if result.contains(value) == false {
                result.append(value)
            }
        }

        return result
    }
}

Makes it super simple. Can be called like this:

let arrayOfInts = [2, 2, 4, 4]
print(arrayOfInts.removeDuplicates()) // Prints: [2, 4]

Filtering based on properties

To filter an array based on properties, you can use this method:

extension Array {

    func filterDuplicates(@noescape includeElement: (lhs:Element, rhs:Element) -> Bool) -> [Element]{
        var results = [Element]()

        forEach { (element) in
            let existingElements = results.filter {
                return includeElement(lhs: element, rhs: $0)
            }
            if existingElements.count == 0 {
                results.append(element)
            }
        }

        return results
    }
}

Which you can call as followed:

let filteredElements = myElements.filterDuplicates { $0.PropertyOne == $1.PropertyOne && $0.PropertyTwo == $1.PropertyTwo }

All answers seem to work fine. If you need to do this many times, be aware that writing

hs.write(name + "\n")

constructs a new string in memory and appends that to the file.

More efficient would be

hs.write(name)
hs.write("\n")

which does not create a new string, just appends to the file.

The following command is needed to force git to send the credentials and authentication method to the proxy:

git config --global http.proxyAuthMethod 'basic'

Source: https://git-scm.com/docs/git-config#git-config-httpproxyAuthMethod

SELECT *, CONVERT( UNCOMPRESS(column) USING "utf8" ) AS column FROM table_name

May this help those who have objects on the list.

If you have a list of objects and wanted to sum specific fields of this object use the below.

List<ResultSom> somList = MyUtil.getResultSom();
BigDecimal result= somList.stream().map(ResultSom::getNetto).reduce(
                                             BigDecimal.ZERO, BigDecimal::add);

You can convert a string to a date easily by:

CAST(YourDate AS DATE)

Start the Mosquitto Broker
Open the terminal and type

mosquitto_sub -h 127.0.0.1 -t topic

Open another terminal and type
mosquitto_pub -h 127.0.0.1 -t topic -m "Hello"

Now you can switch to the previous terminal and there you can able to see the "Hello" Message.One terminal acts as publisher and another one subscriber.

If you want a single JavaScript object such as the following:

{ uniqueIDofSelect: "uniqueID", optionValue: "2" }

(where option 2, "Absent", is the current selection) then the following code should produce it:

  var jsObj = null;
  var status = document.getElementsByName("status")[0];
  for (i = 0, i < status.options.length, ++i) {
     if (options[i].selected ) {
        jsObj = { uniqueIDofSelect: status.id, optionValue: options[i].value };
        break;
     }
  }

If you want an array of all such objects (not just the selected one), use michael's code but swap out status.options[i].text for status.id.

If you want a string that contains a JSON representation of the selected object, use this instead:

  var jsonStr = "";
  var status = document.getElementsByName("status")[0];
  for (i = 0, i < status.options.length, ++i) {
     if (options[i].selected ) {
        jsonStr = '{ '
                  + '"uniqueIDofSelect" : '
                  + '"' + status.id + '"'
                  + ", "
                  + '"optionValue" : '
                  + '"'+ options[i].value + '"'
                  + ' }';
        break;
     }
  }

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

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

This is behavior specified in the Java API's String.valueOf(Object) method. When you do concatenation, valueOf is used to get the String representation. There is a special case if the Object is null, in which case the string "null" is used.

public static String valueOf(Object obj)

Returns the string representation of the Object argument.

Parameters: obj - an Object.

Returns:

if the argument is null, then a string equal to "null"; otherwise, the value of obj.toString() is returned.

Be aware that passing an Object with named properties as Ken suggested adds the cost of allocating and releasing the temporary object to every call. Passing normal arguments by value or reference will generally be the most efficient. For many applications though the performance is not critical but for some it can be.

If I understand correctly. In order to group your results as requested, your Group By clause needs to have the same expression as your select statement.

GROUP BY MONTH(date) + '.' + YEAR(date)

To display the date as "month-date" format change the '.' to '-' The full syntax would be something like this.

SELECT MONTH(date) + '-' + YEAR(date) AS Mjesec, SUM(marketingExpense) AS
SumaMarketing, SUM(revenue) AS SumaZarada 
FROM [Order]
WHERE (idCustomer = 1) AND (date BETWEEN '2001-11-3' AND '2011-11-3')
GROUP BY MONTH(date) + '.' + YEAR(date)

For me, the easiest way is using library called Retrofit2

We just need to create an Interface that contain our request method, parameters, and also we can make custom header for each request :

    public interface MyService {

      @GET("users/{user}/repos")
      Call<List<Repo>> listRepos(@Path("user") String user);

      @GET("user")
      Call<UserDetails> getUserDetails(@Header("Authorization") String   credentials);

      @POST("users/new")
      Call<User> createUser(@Body User user);

      @FormUrlEncoded
      @POST("user/edit")
      Call<User> updateUser(@Field("first_name") String first, 
                            @Field("last_name") String last);

      @Multipart
      @PUT("user/photo")
      Call<User> updateUser(@Part("photo") RequestBody photo, 
                            @Part("description") RequestBody description);

      @Headers({
        "Accept: application/vnd.github.v3.full+json",
        "User-Agent: Retrofit-Sample-App"
      })
      @GET("users/{username}")
      Call<User> getUser(@Path("username") String username);    

    }

And the best is, we can do it asynchronously easily using enqueue method

<html>
<head>
<title>example</title>
    <script> 
   $(function(){
       $('#filename').load("htmlfile.html");
   });
    </script>
</head>
<body>
    <div id="filename">
    </div>
</body>

I need some extra operation based on the result of aggregate function. Finally I've found some solution for aggregate function and the operation based on the result in MongoDB. I've a collection Request with field request, source, status, requestDate.

Single Field Group By & Count:

db.Request.aggregate([
    {"$group" : {_id:"$source", count:{$sum:1}}}
])

Multiple Fields Group By & Count:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}}
])

Multiple Fields Group By & Count with Sort using Field:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}},
    {$sort:{"_id.source":1}}
])

Multiple Fields Group By & Count with Sort using Count:

db.Request.aggregate([
    {"$group" : {_id:{source:"$source",status:"$status"}, count:{$sum:1}}},
    {$sort:{"count":-1}}
])

From what I understand you can't pass an arguments to a filter function (when using the 'filter' filter). What you would have to do is to write a custom filter, sth like this:

.filter('weDontLike', function(){

return function(items, name){

    var arrayToReturn = [];        
    for (var i=0; i<items.length; i++){
        if (items[i].name != name) {
            arrayToReturn.push(items[i]);
        }
    }

    return arrayToReturn;
};

Here is the working jsFiddle: http://jsfiddle.net/pkozlowski_opensource/myr4a/1/

The other simple alternative, without writing custom filters is to store a name to filter out in a scope and then write:

$scope.weDontLike = function(item) {
  return item.name != $scope.name;
};

In the end after trying many of these complicated solutions as I only needed to save/restore a single value in my Fragment (the content of an EditText), and although it might not be the most elegant solution, creating a SharedPreference and storing my state there worked for me

You need to have a height in the div <div style="overflow:hidden"> else it doesnt know what 100% is.

app.factory('persistObject', function () {

        var persistObject = [];

        function set(objectName, data) {
            persistObject[objectName] = data;
        }
        function get(objectName) {
            return persistObject[objectName];
        }

        return {
            set: set,
            get: get
        }
    });

Fill it with data like this

persistObject.set('objectName', data); 

Get the object data like this

persistObject.get('objectName'); 

try this ( stringWithFormat has to start with lowercase)

 [NSString stringWithFormat:@"%@\n%@",string1,string2];

Try:

=ArrayFormula(QUERY(A:A&{"",""};"select Col1, count(Col2) where Col1 != '' group by Col1 label count(Col2) 'Count'";1))

22/07/2014 Some time in the last month, Sheets has started supporting more flexible concatenation of arrays, using an embedded array. So the solution may be shortened slightly to:

=QUERY({A:A,A:A},"select Col1, count(Col2) where Col1 != '' group by Col1 label count(Col2) 'Count'",1)

As mentioned by ecdpalma below, git 1.7.12+ (August 2012) has enhanced the option --root for git rebase:

"git rebase [-i] --root $tip" can now be used to rewrite all the history leading to "$tip" down to the root commit.

That new behavior was initially discussed here:

I personally think "git rebase -i --root" should be made to just work without requiring "--onto" and let you "edit" even the first one in the history.
It is understandable that nobody bothered, as people are a lot less often rewriting near the very beginning of the history than otherwise.

The patch followed.

(original answer, February 2010)

As mentioned in the Git FAQ (and this SO question), the idea is:

1. Create new temporary branch
2. Rewind it to the commit you want to change using git reset --hard
3. Change that commit (it would be top of current HEAD, and you can modify the content of any file)

4. Rebase branch on top of changed commit, using:

   git rebase --onto <tmp branch> <commit after changed> <branch>`
   

The trick is to be sure the information you want to remove is not reintroduced by a later commit somewhere else in your file. If you suspect that, then you have to use filter-branch --tree-filter to make sure the content of that file does not contain in any commit the sensible information.

In both cases, you end up rewriting the SHA1 of every commit, so be careful if you have already published the branch you are modifying the contents of. You probably shouldn’t do it unless your project isn’t yet public and other people haven’t based work off the commits you’re about to rewrite.

I have a simpler solution for you:

window.onload = window.onresize = (event) => {
    //Your Code Here
}

I've tested this an it works great, on the plus side it's compact and uncomplicated like the other examples here.

What you are looking for can be found here. It may exist a more elegant way to accomplish that, but one possible approach is

Option 1 (preferred):

final Duration timeout = Duration.ofSeconds(30);
ExecutorService executor = Executors.newSingleThreadExecutor();

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

try {
    handler.get(timeout.toMillis(), TimeUnit.MILLISECONDS);
} catch (TimeoutException e) {
    handler.cancel(true);
}

executor.shutdownNow();

Option 2:

final Duration timeout = Duration.ofSeconds(30);
ScheduledExecutorService executor = Executors.newScheduledThreadPool(1);

final Future<String> handler = executor.submit(new Callable() {
    @Override
    public String call() throws Exception {
        return requestDataFromModem();
    }
});

executor.schedule(new Runnable() {
    @Override
    public void run(){
        handler.cancel(true);
    }      
}, timeout.toMillis(), TimeUnit.MILLISECONDS);

executor.shutdownNow();

Those are only a draft so that you can get the main idea.

You can observe the relation between features either by drawing a heat map from seaborn or scatter matrix from pandas.

Scatter Matrix:

pd.scatter_matrix(dataframe, alpha = 0.3, figsize = (14,8), diagonal = 'kde');

If you want to visualize each feature's skewness as well - use seaborn pairplots.

sns.pairplot(dataframe)

Sns Heatmap:

import seaborn as sns

f, ax = pl.subplots(figsize=(10, 8))
corr = dataframe.corr()
sns.heatmap(corr, mask=np.zeros_like(corr, dtype=np.bool), cmap=sns.diverging_palette(220, 10, as_cmap=True),
            square=True, ax=ax)

The output will be a correlation map of the features. i.e. see the below example.

The correlation between grocery and detergents is high. Similarly:

1. Grocery and Detergents.

1. Milk and Grocery
2. Milk and Detergents_Paper

1. Milk and Deli
2. Frozen and Fresh.
3. Frozen and Deli.

From Pairplots: You can observe same set of relations from pairplots or scatter matrix. But from these we can say that whether the data is normally distributed or not.

Note: The above is same graph taken from the data, which is used to draw heatmap.

Here's yet another solution. This uses POSIX substring parameter expansion, so it works in Bash, Dash, KornShell (ksh), Z shell (zsh), etc.

test "${string#*$word}" != "$string" && echo "$word found in $string"

A functionalized version with some examples:

# contains(string, substring)
#
# Returns 0 if the specified string contains the specified substring,
# otherwise returns 1.
contains() {
    string="$1"
    substring="$2"
    if test "${string#*$substring}" != "$string"
    then
        return 0    # $substring is in $string
    else
        return 1    # $substring is not in $string
    fi
}

contains "abcd" "e" || echo "abcd does not contain e"
contains "abcd" "ab" && echo "abcd contains ab"
contains "abcd" "bc" && echo "abcd contains bc"
contains "abcd" "cd" && echo "abcd contains cd"
contains "abcd" "abcd" && echo "abcd contains abcd"
contains "" "" && echo "empty string contains empty string"
contains "a" "" && echo "a contains empty string"
contains "" "a" || echo "empty string does not contain a"
contains "abcd efgh" "cd ef" && echo "abcd efgh contains cd ef"
contains "abcd efgh" " " && echo "abcd efgh contains a space"

You shouldn't really be de-encrypting passwords.

You should be encrypting the password entered into your application and comparing against the encrypted password from the database.

Edit - and if this is because the password has been forgotten, then setup a mechanism to create a new password.

In my humble opinion, I understand this question in this way:

[CASE 1] When you start an absolute-import like

python -m test_A.test

or

import test_A.test

or

from test_A import test

you're actually setting the import-anchor to be test_A, in other word, top-level package is test_A . So, when we have test.py do from ..A import xxx, you are escaping from the anchor, and Python does not allow this.

[CASE 2] When you do

python -m package.test_A.test

or

from package.test_A import test

your anchor becomes package, so package/test_A/test.py doing from ..A import xxx does not escape the anchor(still inside package folder), and Python happily accepts this.

In short:

• Absolute-import changes current anchor (=redefines what is the top-level package);
• Relative-import does not change the anchor but confines to it.

Furthermore, we can use full-qualified module name(FQMN) to inspect this problem.

Check FQMN in each case:

• [CASE2] test.__name__ = package.test_A.test
• [CASE1] test.__name__ = test_A.test

So, for CASE2, an from .. import xxx will result in a new module with FQMN=package.xxx, which is acceptable.

While for CASE1, the .. from within from .. import xxx will jump out of the starting node(anchor) of test_A, and this is NOT allowed by Python.

Better option is use SQLQuery#addScalar than casting to Long or BigDecimal.

Here is modified query that returns count column as Long

Query query = session
             .createSQLQuery("SELECT COUNT(*) as count
                             FROM SpyPath 
                             WHERE DATE(time)>=DATE_SUB(CURDATE(),INTERVAL 6 DAY) 
                             GROUP BY DATE(time) 
                             ORDER BY time;")
             .addScalar("count", LongType.INSTANCE);

Then

List<Long> result = query.list(); //No ClassCastException here

On CodeProject, there is an article that briefly discusses pros and cons of testing private methods. It then provides some reflection code to access private methods (similar to the code Marcus provides above.) The only issue I've found with the sample is that the code doesn't take into account overloaded methods.

You can find the article here:

http://www.codeproject.com/KB/cs/testnonpublicmembers.aspx

Make sure you are running the test as a superuser.

sudo nginx -t

Or the test wont have all the permissions needed to complete the test properly.

public ActionResult GetAjaxValue()
{
   return Content("string value");
}

Use This Code

@echo off
:: Get the current directory

for /f "tokens=* delims=/" %%A in ('cd') do set CURRENT_DIR=%%A

echo CURRENT_DIR%%A 

(echo this To confirm this code works fine)

You need to write it like sprintf(aa, "%9.7lf", a)

Check out http://en.wikipedia.org/wiki/Printf for some more details on format codes.

I have Notepad++ 5.3.1 (UNICODE). I haven't done any magic and it works fine for me as described by you.

Maybe it depends on the (programming/markup/...) "Language"?

If you are just looking to replace the slugs in your routes, you can use generatePath that was introduced in react-router 4.3 (2018). As of today, it isn't included in the react-router-dom (web) documentation, but is in react-router (core). Issue#7679

// myRoutes.js
export const ROUTES = {
  userDetails: "/user/:id",
}


// MyRouter.jsx
import ROUTES from './routes'

<Route path={ROUTES.userDetails} ... />


// MyComponent.jsx
import { generatePath } from 'react-router-dom'
import ROUTES from './routes'

<Link to={generatePath(ROUTES.userDetails, { id: 1 })}>ClickyClick</Link>

It's the same concept that django.urls.reverse has had for a while.

The SpeechRecognition library requires Python 3.3 or up:

[...]

The first software requirement is Python 3.3 or better. This is required to use the library.

The urllib.request module is part of the Python 3 standard library; in Python 2 you'd use urllib2 here.

jQuery + CSS for img

With jQuery this is working for me :

$('img').error(function() {
    $(this).attr('src', '/no-img.png').addClass('no-img');
});

And I can use this picture everywhere on my website regardless of the size of it with the following CSS3 property :

img.no-img {
    object-fit: cover;
    object-position: 50% 50%;
}

TIP 1 : use a square image of at least 800 x 800 pixels.

TIP 2 : for use with portrait of people, use object-position: 20% 50%;

CSS only for background-img

For missing background images, I also added the following on each background-image declaration :

background-image: url('path-to-image.png'), url('no-img.png');

NOTE : not working for transparent images.

Apache server side

Another solution is to detect missing image with Apache before to send to browser and remplace it by the default no-img.png content.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} /images/.*\.(gif|jpg|jpeg|png)$
RewriteRule .* /images/no-img.png [L,R=307]

@Column(nullable = false, updatable = false)
@CreationTimestamp
private Date created_at;

this worked for me. more info

You have to use CSS. Here's an example of changing the default link color, when the link is just sitting there, when it's being hovered and when it's an active link.

a:link {_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
a:hover {_x000D_
  color: blue;_x000D_
}_x000D_
_x000D_
a:active {_x000D_
  color: green;_x000D_
}

The answer from @aioobe is excellent. I just want to add another way for Java 8.

int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };

Arrays.sort(twoDim, (int[] o1, int[] o2) -> o2[0] - o1[0]);

System.out.println(Arrays.deepToString(twoDim));

For me it's intuitive and easy to remember with Java 8 syntax.

This is more compact and respect the intial first position in array and just use the inital bound to add old value.

Public Sub ReDimPreserve(ByRef arr, ByVal size1 As Long, ByVal size2 As Long)
Dim arr2 As Variant
Dim x As Long, y As Long

'Check if it's an array first
If Not IsArray(arr) Then Exit Sub

'create new array with initial start
ReDim arr2(LBound(arr, 1) To size1, LBound(arr, 2) To size2)

'loop through first
For x = LBound(arr, 1) To UBound(arr, 1)
    For y = LBound(arr, 2) To UBound(arr, 2)
        'if its in range, then append to new array the same way
        arr2(x, y) = arr(x, y)
    Next
Next
'return byref
arr = arr2
End Sub

I call this sub with this line to resize the first dimension

ReDimPreserve arr2, UBound(arr2, 1) + 1, UBound(arr2, 2)

You can add an other test to verify if the initial size is not upper than new array. In my case it's not necessary

You have said you can only load scripts from your own site (self). You have then tried to load a script from another site (www.google.com) and, because you've restricted this, you can't. That's the whole point of Content Security Policy (CSP).

You can change your first line to:

<meta http-equiv="Content-Security-Policy" content="default-src *; style-src 'self' 'unsafe-inline'; script-src 'self' 'unsafe-inline' 'unsafe-eval' http://www.google.com">

Or, alternatively, it may be worth removing that line completely until you find out more about CSP. Your current CSP is pretty lax anyway (allowing unsafe-inline, unsafe-eval and a default-src of *), so it is probably not adding too much value, to be honest.

You can make a template function, and pass the array by reference to achieve this.

Here is my code snippet

template <typename TypeOfData>


void PrintArray(TypeOfData &arrayOfType);

int main()

{

    char charArray[] = "my name is";

    int intArray[] = { 1,2,3,4,5,6 };

    double doubleArray[] = { 1.1,2.2,3.3 };


    PrintArray(charArray);

    PrintArray(intArray);

    PrintArray(doubleArray);

}


template <typename TypeOfData>

void PrintArray(TypeOfData &arrayOfType)

{

    int elementsCount = sizeof(arrayOfType) / sizeof(arrayOfType[0]);


    for (int i = 0; i < elementsCount; i++)

    {

        cout << "Value in elements at position " << i + 1 << " is " << arrayOfType[i] << endl;

    }

}

here is the full program to make a POST rest call using spring's RestTemplate.

import java.util.HashMap;
import java.util.Map;

import org.springframework.http.HttpEntity;
import org.springframework.http.ResponseEntity;
import org.springframework.util.LinkedMultiValueMap;
import org.springframework.util.MultiValueMap;
import org.springframework.web.client.RestTemplate;

import com.ituple.common.dto.ServiceResponse;

   public class PostRequestMain {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
        Map map = new HashMap<String, String>();
        map.put("Content-Type", "application/json");

        headers.setAll(map);

        Map req_payload = new HashMap();
        req_payload.put("name", "piyush");

        HttpEntity<?> request = new HttpEntity<>(req_payload, headers);
        String url = "http://localhost:8080/xxx/xxx/";

        ResponseEntity<?> response = new RestTemplate().postForEntity(url, request, String.class);
        ServiceResponse entityResponse = (ServiceResponse) response.getBody();
        System.out.println(entityResponse.getData());
    }

}

In python, Suppose you have loaded up the data in some variable train:

train = pandas.read_csv('file_name')
>>> train
train([[ 1.,  2.,  3.],
        [ 5.,  1.,  2.]],)

I want to check what are the dimensions of the 'file_name'. I have stored the file in train

>>>train.shape
(2,3)
>>>train.shape[0]              # will display number of rows
2
>>>train.shape[1]              # will display number of columns
3

For-loops:

For-loop in C:

for(int x = 0; x<=3; x++)
{
    //Do something!
}

The same loop in 8086 assembler:

        xor cx,cx   ; cx-register is the counter, set to 0
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        inc cx      ; Increment
        cmp cx,3    ; Compare cx to the limit
        jle loop1   ; Loop while less or equal

That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:

        mov cx,4    ; 4 iterations
loop1   nop         ; Whatever you wanna do goes here, should not change cx
        loop loop1  ; loop instruction decrements cx and jumps to label if not 0

If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction

times 4 nop

Do-while-loops

Do-while-loop in C:

int x=1;
do{
    //Do something!
}
while(x==1)

The same loop in assembler:

        mov ax,1
loop1   nop         ; Whatever you wanna do goes here
        cmp ax,1    ; Check wether cx is 1
        je loop1    ; And loop if equal

While-loops

While-loop in C:

while(x==1){
    //Do something
}

The same loop in assembler:

        jmp loop1   ; Jump to condition first
cloop1  nop         ; Execute the content of the loop
loop1   cmp ax,1    ; Check the condition
        je cloop1   ; Jump to content of the loop if met

For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.

You can also use str.partition:

>>> text = "123mango abcd mango kiwi peach"

>>> text.partition("mango")
('123', 'mango', ' abcd mango kiwi peach')

>>> text.partition("mango")[-1]
' abcd mango kiwi peach'

>>> text.partition("mango")[-1].lstrip()  # if whitespace strip-ing is needed
'abcd mango kiwi peach'

The advantage of using str.partition is that it's always gonna return a tuple in the form:

(<pre>, <separator>, <post>)

So this makes unpacking the output really flexible as there's always going to be 3 elements in the resulting tuple.

I'm sad to say: We are sh*t out of luck on this one.

I'd like to refer you to the author of WhichBrowser: Everybody lies.

Basically, no browser is being honest. No matter if you use Chrome or IE, they both will tell you that they are "Mozilla Netscape" with Gecko and Safari support. Try it yourself on any of the fiddles flying around in this thread:

hims056's fiddle

Hariharan's fiddle

or any other... Try it with Chrome (which might still succeed), then try it with a recent version of IE, and you will cry. Of course, there are heuristics, to get it all right, but it will be tedious to grasp all the edge cases, and they will very likely not work anymore in a year's time.

Take your code, for example:

<div id="example"></div>
<script type="text/javascript">
txt = "<p>Browser CodeName: " + navigator.appCodeName + "</p>";
txt+= "<p>Browser Name: " + navigator.appName + "</p>";
txt+= "<p>Browser Version: " + navigator.appVersion + "</p>";
txt+= "<p>Cookies Enabled: " + navigator.cookieEnabled + "</p>";
txt+= "<p>Platform: " + navigator.platform + "</p>";
txt+= "<p>User-agent header: " + navigator.userAgent + "</p>";
document.getElementById("example").innerHTML=txt;
</script>

Chrome says:

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.115 Safari/537.36

IE says:

Browser CodeName: Mozilla

Browser Name: Netscape

Browser Version: 5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko

Cookies Enabled: true

Platform: Win32

User-agent header: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; .NET4.0C; .NET4.0E; InfoPath.3; rv:11.0) like Gecko

At least Chrome still has a string that contains "Chrome" with the exact version number. But, for IE you must extrapolate from the things it supports to actually figure it out (who else would boast that they support .NET or Media Center :P), and then match it against the rv: at the very end to get the version number. Of course, even such sophisticated heuristics might very likely fail as soon as IE 12 (or whatever they want to call it) comes out.

Give 0777 to all files and directories starting from the current path :

chmod -R 0777 ./

Minimal example

And just to make what Mizux said as a minimal example:

main_c.c

#include <stdio.h>

int main(void) {
    puts("hello");
}

main_cpp.cpp

#include <iostream>

int main(void) {
    std::cout << "hello" << std::endl;
}

Then, without any Makefile:

make CFLAGS='-g -O3' \
     CXXFLAGS='-ggdb3 -O0' \
     CPPFLAGS='-DX=1 -DY=2' \
     CCFLAGS='--asdf' \
     main_c \
     main_cpp

runs:

cc -g -O3 -DX=1 -DY=2   main_c.c   -o main_c
g++ -ggdb3 -O0 -DX=1 -DY=2   main_cpp.cpp   -o main_cpp

So we understand that:

• make had implicit rules to make main_c and main_cpp from main_c.c and main_cpp.cpp
• CFLAGS and CPPFLAGS were used as part of the implicit rule for .c compilation
• CXXFLAGS and CPPFLAGS were used as part of the implicit rule for .cpp compilation
• CCFLAGS is not used

Those variables are only used in make's implicit rules automatically: if compilation had used our own explicit rules, then we would have to explicitly use those variables as in:

main_c: main_c.c
    $(CC) $(CFLAGS) $(CPPFLAGS) -o $@ $<

main_cpp: main_c.c
    $(CXX) $(CXXFLAGS) $(CPPFLAGS) -o $@ $<

to achieve a similar affect to the implicit rules.

We could also name those variables however we want: but since Make already treats them magically in the implicit rules, those make good name choices.

Here is the regex for the Internet Email Address using the RegularExpressionValidator in .NET

\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*

By the way if you put a RegularExpressionValidator on the page and go to the design view there is a ValidationExpression field that you can use to choose from a list of expressions provided by .NET. Once you choose the expression you want there is a Validation expression: textbox that holds the regex used for the validator

I want to give an advice on how to monitor application for the memory leaks with the tools that are available in JVM. It doesn't show how to generate the memory leak but explains how to detect it with minimum tools available.

You need to monitor Java memory consumption first.

The simplest way to do this is to use jstat utility that comes with JVM.

jstat -gcutil <process_id> <timeout>

It will report memory consumption for each generation (Young, Eldery and Old) and garbage collection times (Young and Full).

As soon as you spot that Full Garbage Collection is executed too often and takes too much time, you can assume that application is leaking memory.

Then you need to create a memory dump using jmap utility:

jmap -dump:live,format=b,file=heap.bin <process_id>

Then you need to analyse heap.bin file with Memory Analyser, Eclipse Memory Analyzer (MAT) for example.

MAT will analyze the memory and provide you suspect information about memory leaks.

As Bakkal explained, for the keyboard shortcuts, in netbeans you can go to tools->options->editor->code templates and add or edit your own shortcuts.

In Eclipse it's on templates.

Get focused child, and use it to get position in adapter.

mRecyclerView.getChildAdapterPosition(mRecyclerView.getFocusedChild())

yes, using *arg passing args to a function will make python unpack the values in arg and pass it to the function.

so:

>>> def printer(*args):
 print args


>>> printer(2,3,4)
(2, 3, 4)
>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)
>>> 

Google has this as a top result for For those who need to find a node with certain text. By way of update, a nodelist is now iterable in modern browsers without having to convert it to an array.

The solution can use forEach like so.

var elList = document.querySelectorAll(".some .selector");
elList.forEach(function(el) {
    if (el.innerHTML.indexOf("needle") !== -1) {
        // Do what you like with el
        // The needle is case sensitive
    }
});

This worked for me to do a find/replace text inside a nodelist when a normal selector could not choose just one node so I had to filter each node one by one to check it for the needle.

I had to update the proxy settings under Plugins -> Plugin Manager -> Show Plugin Manager -> Settings to see any PlugIns in the "Available" list.

After that, installing "XML Tools" was easy and did the requested job as described above.

For macOS catalina try this : open Xcode. if not existing. download from App store (about 11GB) then open Xcode>open developer tool>more developer tool and used my apple id to download a compatible command line tool. Then, after downloading, I opened Xcode>Preferences>Locations>Command Line Tool and selected the newly downloaded command line tool from downloads.

This button post to the current page while at the same time opens OtherPage.aspx in a new browser window. I think this is what you mean with ...the original page and the newly launched page should both be launched.

<asp:Button ID="myBtn" runat="server" Text="Click me" 
     onclick="myBtn_Click" OnClientClick="window.open('OtherPage.aspx', 'OtherPage');" />

This should work in Matlab:

set(gca, 'XAxisLocation', 'origin')

Options are: bottom, top, origin.

For Y.axis:

YAxisLocation; left, right, origin

The following is a nice expedient solution that works with GitHub for checking out the PR branch from another user's fork. You need to know the pull request ID (which GitHub displays along with the PR title).

Example:

Fixing your insecure code #8
alice wants to merge 1 commit into your_repo:master from her_repo:branch

git checkout -b <branch>
git pull origin pull/8/head

Substitute your remote if different from origin.
Substitute 8 with the correct pull request ID.

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

In my experience there are two places where we want to use uint8_t to mean 8 bits (and uint16_t, etc) and where we can have fields smaller than 8 bits. Both places are where space matters and we often need to look at a raw dump of the data when debugging and need to be able to quickly determine what it represents.

The first is in RF protocols, especially in narrow-band systems. In this environment we may need to pack as much information as we can into a single message. The second is in flash storage where we may have very limited space (such as in embedded systems). In both cases we can use a packed data structure in which the compiler will take care of the packing and unpacking for us:

#pragma pack(1)
typedef struct {
  uint8_t    flag1:1;
  uint8_t    flag2:1;
  padding1   reserved:6;  /* not necessary but makes this struct more readable */
  uint32_t   sequence_no;
  uint8_t    data[8];
  uint32_t   crc32;
} s_mypacket __attribute__((packed));
#pragma pack()

Which method you use depends on your compiler. You may also need to support several different compilers with the same header files. This happens in embedded systems where devices and servers can be completely different - for example you may have an ARM device that communicates with an x86 Linux server.

There are a few caveats with using packed structures. The biggest gotcha is that you must avoid dereferencing the address of a member. On systems with mutibyte aligned words, this can result in a misaligned exception - and a coredump.

Some folks will also worry about performance and argue that using these packed structures will slow down your system. It is true that, behind the scenes, the compiler adds code to access the unaligned data members. You can see that by looking at the assembly code in your IDE.

But since packed structures are most useful for communication and data storage then the data can be extracted into a non-packed representation when working with it in memory. Normally we do not need to be working with the entire data packet in memory anyway.

Here is some relevant discussion:

pragma pack(1) nor __attribute__ ((aligned (1))) works

Is gcc's __attribute__((packed)) / #pragma pack unsafe?

If you are using spring, there's a util class available in spring-core. You can simply do

import org.springframework.util.SerializationUtils;

byte[] bytes = SerializationUtils.serialize(anyObject);
Object object = SerializationUtils.deserialize(bytes);

• window.opener refers to the window that called window.open( ... ) to open the window from which it's called
• window.parent refers to the parent of a window in a <frame> or <iframe>
• window.top refers to the top-most window from a window nested in one or more layers of <iframe> sub-windows

Those will be null (or maybe undefined) when they're not relevant to the referring window's situation. ("Referring window" means the window in whose context the JavaScript code is run.)

If you are using Anti-Virus, you can first check virus chest and restore from there. Otherwise, just go to your SDK Manager and install Android SDK Tools.

You could combine them, use jQuery to bind the function to the click

<div id="myDiv">Some Content</div>

$('#myDiv').click(divFunction);

function divFunction(){

i think unlink & link php versions are not enough because we are often using php with apache(httpd), so need to update httpd.conf after switch php version.

i have write shell script for disable/enable php_module automatically inside httpd.conf, look at line 46 to line 54 https://github.com/dangquangthai/switch-php-version-on-mac-sierra/blob/master/switch-php#L46

Follow my steps:

1) Check installed php versions by brew, for sure everything good

> brew list | grep php
#output
php56
php56-intl
php56-mcrypt
php71
php71-intl
php71-mcrypt

2) Run script

> switch-php 71 # or switch-php 56
#output
PHP version [71] found
Switching from [php56] to [php71] ... 
Unlink php56 ... [OK] and Link php71 ... [OK]
Updating Apache2.4 Configuration /usr/local/etc/httpd/httpd.conf ... [OK]
Restarting Apache2.4 ... [OK]
PHP 7.1.11 (cli) (built: Nov  3 2017 08:48:02) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.1.0, Copyright (c) 1998-2017 Zend Technologies

3) Finally, when your got above message, check httpd.conf, in my laptop:

vi /usr/local/etc/httpd/httpd.conf

You can see near by LoadModule lines

LoadModule php7_module /usr/local/Cellar/php71/7.1.11_22/libexec/apache2/libphp7.so
#LoadModule php5_module /usr/local/Cellar/php56/5.6.32_8/libexec/apache2/libphp5.so

4) open httpd://localhost/info.php

i hope it helpful

An easy way is to just define a custom Button class which accepts all the properties that you desire like radius, gradient, pressed color, normal color etc. and then just use that in your XML layouts instead of setting up the background using XML. A sample is here

This is extremely useful if you have a lot of buttons with same properties like radius, selected color etc. You can customize your inherited button to handle these additional properties.

Result (No Background selector was used).

Normal Button

Pressed Button

This single line of code solved the problem for me:

event.currentTarget.getAttribute('data-tag')

Jquery or Javascipt doesn't provide a built-in method to achieve this.

CSS test transform (text-transform:capitalize;) doesn't really capitalize the string's data but shows a capitalized rendering on the screen.

If you are looking for a more legit way of achieving this in the data level using plain vanillaJS, use this solution =>

var capitalizeString = function (word) {    
    word = word.toLowerCase();
    if (word.indexOf(" ") != -1) { // passed param contains 1 + words
        word = word.replace(/\s/g, "--");
        var result = $.camelCase("-" + word);
        return result.replace(/-/g, " ");
    } else {
    return $.camelCase("-" + word);
    }
}

We use a pretty convenient command line to force re-deployment of fresh images on integration pod.
We noticed that our alpine containers all run their "sustaining" command on PID 5. Therefore, sending it a SIGTERM signal takes the container down. imagePullPolicy being set to Always has the kubelet re-pull the latest image when it brings the container back.

kubectl exec -i [pod name] -c [container-name] -- kill -15 5

If anyone encounter the same issue, when trying to dump from elasticsearch <2.0 to >2.0 you need to do:

elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=analyzer
elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=mapping
elasticdump --input=http://localhost:9200/$SRC_IND --output=http://$TARGET_IP:9200/$TGT_IND --type=data --transform "delete doc.__source['_id']"

Use include("class.classname.php");

And class should use <?php //code ?> not <? //code ?>

I have read out very clear definitions for these terms.

Protected : Access is limited to within the class definition and any class that inherits from the class. The type or member can be accessed only by code in the same class or struct or in a class that is derived from that class.

Internal : Access is limited to exclusively to classes defined within the current project assembly. The type or member can be accessed only by code in same class.

Protected-Internal : Access is limited to current assembly or types derived from containing class.

You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.

It seems that you've omitted the value attribute in HTML markup.

Add it there as <input value="" ... >.

The atob function will decode a Base64-encoded string into a new string with a character for each byte of the binary data.

const byteCharacters = atob(b64Data);

Each character's code point (charCode) will be the value of the byte. We can create an array of byte values by applying this using the .charCodeAt method for each character in the string.

const byteNumbers = new Array(byteCharacters.length);
for (let i = 0; i < byteCharacters.length; i++) {
    byteNumbers[i] = byteCharacters.charCodeAt(i);
}

You can convert this array of byte values into a real typed byte array by passing it to the Uint8Array constructor.

const byteArray = new Uint8Array(byteNumbers);

This in turn can be converted to a BLOB by wrapping it in an array and passing it to the Blob constructor.

const blob = new Blob([byteArray], {type: contentType});

The code above works. However the performance can be improved a little by processing the byteCharacters in smaller slices, rather than all at once. In my rough testing 512 bytes seems to be a good slice size. This gives us the following function.

const b64toBlob = (b64Data, contentType='', sliceSize=512) => {
  const byteCharacters = atob(b64Data);
  const byteArrays = [];

  for (let offset = 0; offset < byteCharacters.length; offset += sliceSize) {
    const slice = byteCharacters.slice(offset, offset + sliceSize);

    const byteNumbers = new Array(slice.length);
    for (let i = 0; i < slice.length; i++) {
      byteNumbers[i] = slice.charCodeAt(i);
    }

    const byteArray = new Uint8Array(byteNumbers);
    byteArrays.push(byteArray);
  }

  const blob = new Blob(byteArrays, {type: contentType});
  return blob;
}

const blob = b64toBlob(b64Data, contentType);
const blobUrl = URL.createObjectURL(blob);

window.location = blobUrl;

Full Example:

const b64toBlob = (b64Data, contentType='', sliceSize=512) => {_x000D_
  const byteCharacters = atob(b64Data);_x000D_

Almost every database table, there's an auto_increment column(generally id )

If you want the last of all the rows in the table,

SELECT columns FROM table ORDER BY id DESC LIMIT 1;

OR

You can combine two queries into single query that looks like this:

SELECT columns FROM table WHERE id=(SELECT MAX(id) FROM table);

_{This is now a multiple-year old question, but being very popular, it's worth mentioning a fantastic resource for learning about the C++11 memory model. I see no point in summing up his talk in order to make this yet another full answer, but given this is the guy who actually wrote the standard, I think it's well worth watching the talk.}

Herb Sutter has a three hour long talk about the C++11 memory model titled "atomic<> Weapons", available on the Channel9 site - part 1 and part 2. The talk is pretty technical, and covers the following topics:

1. Optimizations, Races, and the Memory Model
2. Ordering – What: Acquire and Release
3. Ordering – How: Mutexes, Atomics, and/or Fences
4. Other Restrictions on Compilers and Hardware
5. Code Gen & Performance: x86/x64, IA64, POWER, ARM
6. Relaxed Atomics

The talk doesn't elaborate on the API, but rather on the reasoning, background, under the hood and behind the scenes (did you know relaxed semantics were added to the standard only because POWER and ARM do not support synchronized load efficiently?).

In most of the cases, StringUtils.isBlank(str) from apache commons library would solve it. But if there is case, where input string being checked has null value within quotes, it fails to check such cases.

Take an example where I have an input object which was converted into string using String.valueOf(obj) API. In case obj reference is null, String.valueOf returns "null" instead of null.

When you attempt to use, StringUtils.isBlank("null"), API fails miserably, you may have to check for such use cases as well to make sure your validation is proper.

Create cmd file with line:

for %%p in (C D E F G H I J K L M N O P Q R S T U V W X Y Z) do if exist "%%p:\$Recycle.Bin" rundll32.exe advpack.dll,DelNodeRunDLL32 "%%p:\$Recycle.Bin"

Another alternative is to use any web hosting with webdav support. You will need some space for this somewhere of course but it is straightforward to set up and a good alternative to running a full blown nexus server.

add this to your build section

     <extensions>
        <extension>
        <artifactId>wagon-webdav-jackrabbit</artifactId>
        <groupId>org.apache.maven.wagon</groupId>
        <version>2.2</version>
        </extension>
    </extensions>

Add something like this to your distributionManagement section

<repository>
    <id>release.repo</id>
    <url>dav:http://repo.jillesvangurp.com/releases/</url>
</repository>

Finally make sure to setup the repository access in your settings.xml

add this to your servers section

    <server>
        <id>release.repo</id>
        <username>xxxx</username>
        <password>xxxx</password>
    </server>

and a definition to your repositories section

            <repository>
                <id>release.repo</id>
                <url>http://repo.jillesvangurp.com/releases</url>
                <releases>
                    <enabled>true</enabled>
                </releases>
                <snapshots>
                    <enabled>false</enabled>
                </snapshots>
            </repository>

Finally, if you have any standard php hosting, you can use something like sabredav to add webdav capabilities.

Advantages: you have your own maven repository Downsides: you don't have any of the management capabilities in nexus; you need some webdav setup somewhere

If, like me, you are still using the browser version (which will be deprecated soon), have you tried the "Code" button?

This should generate a snippet which contains the entire request Postman is firing. You can even choose the language for the snippet. I find it quite handy when I need to debug stuff.

Hope this helps.

Does it have to be String.Format?

This looks like a job for String.Padleft

myString=myString.PadLeft(3, '0');

Or, if you are converting direct from an int:

myInt.toString("D3");

Does this work?

display_errors = Off

Also, what version of php are you using?

Instead of using np.argsort you could use np.argpartition - if you only need the indices of the lowest/highest n elements.

That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:

>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2]  # indices of lowest 2 items
array([0, 4], dtype=int64)

>>> np.array(avgDists).argpartition(-2)[-2:]  # indices of highest 2 items
array([1, 3], dtype=int64)

Your settings must be incorrect.

Go to http://www.facebook.com/developers/ and edit the application you're working on.

On the "website" tab, look for "Site URL". This should be set to your website's URL "http://yoursite.com/"

Note that if you're using subdomains, you'll also need to update "Site Domain" to be "yoursite.com"

The JSON you posted looks fine, however in your code, it is most likely not a JSON string anymore, but already a JavaScript object. This means, no more parsing is necessary.

You can test this yourself, e.g. in Chrome's console:

new Object().toString()
// "[object Object]"

JSON.parse(new Object())
// Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse("[object Object]")
// Uncaught SyntaxError: Unexpected token o in JSON at position 1

JSON.parse() converts the input into a string. The toString() method of JavaScript objects by default returns [object Object], resulting in the observed behavior.

Try the following instead:

var newData = userData.data.userList;

A simple example loading images into the tiles.

The Flutter Gallery app contains a real world example, which can be found here.

If you use tostring you lose information on both shape and data type:

>>> import numpy as np
>>> a = np.arange(12).reshape(3, 4)
>>> a
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])
>>> s = a.tostring()
>>> aa = np.fromstring(a)
>>> aa
array([  0.00000000e+000,   4.94065646e-324,   9.88131292e-324,
         1.48219694e-323,   1.97626258e-323,   2.47032823e-323,
         2.96439388e-323,   3.45845952e-323,   3.95252517e-323,

>>> aa = np.fromstring(a, dtype=int).reshape(3, 4)
>>> aa
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

This means you have to send the metadata along with the data to the recipient. To exchange auto-consistent objects, try cPickle:

>>> import cPickle
>>> s = cPickle.dumps(a)
>>> cPickle.loads(s)
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])

myControl.Left = (this.ClientSize.Width - myControl.Width) / 2 ;
myControl.Top = (this.ClientSize.Height - myControl.Height) / 2;

You should simply install request locally within your project.

Just cd to the folder containing your js file and run

npm install request

You can use strrchr() to find last occurence of .(dot) and get .(dot) based extensions files. Check the below code for example.

#include<stdio.h>

void GetFileExtension(const char* file_name) {

    int ext = '.';
    const char* extension = NULL;
    extension = strrchr(file_name, ext);

    if(extension == NULL){
        printf("Invalid extension encountered\n");
        return;
    }

    printf("File extension is %s\n", extension);
}

int main()
{
    const char* file_name = "c:\\.directoryname\\file.name.with.too.many.dots.ext";
    GetFileExtension(file_name);
    return 0;
}

You could add an OUTPUT parameter to test2, and set it to the new id straight after the INSERT using:

SELECT @NewIdOutputParam = SCOPE_IDENTITY()

Then in test1, retrieve it like so:

DECLARE @NewId INTEGER
EXECUTE test2 @NewId OUTPUT
-- Now use @NewId as needed

Asked question title is general, but authors use case stated in the body of the question is specific. So any other answers may be used.

But in order to fully answer the title question it should be clarified that it seems like all of the approaches may fail in some cases and require some rework. I reviewed all of them (and some additional) in decreasing of reliability order (in my opinion):

1. Comparing types directly via == (accepted answer).

Despite the fact that this is accepted answer and has most upvotes count, I think this method should not be used at all. Because in fact this approach is discouraged in python as mentioned several times here.
But if one still want to use it - should be aware of some pandas-specific dtypes like pd.CategoricalDType, pd.PeriodDtype, or pd.IntervalDtype. Here one have to use extra type( ) in order to recognize dtype correctly:

s = pd.Series([pd.Period('2002-03','D'), pd.Period('2012-02-01', 'D')])
s
s.dtype == pd.PeriodDtype   # Not working
type(s.dtype) == pd.PeriodDtype # working 

>>> 0    2002-03-01
>>> 1    2012-02-01
>>> dtype: period[D]
>>> False
>>> True

Another caveat here is that type should be pointed out precisely:

s = pd.Series([1,2])
s
s.dtype == np.int64 # Working
s.dtype == np.int32 # Not working

>>> 0    1
>>> 1    2
>>> dtype: int64
>>> True
>>> False

2. isinstance() approach.

This method has not been mentioned in answers so far.

So if direct comparing of types is not a good idea - lets try built-in python function for this purpose, namely - isinstance().
It fails just in the beginning, because assumes that we have some objects, but pd.Series or pd.DataFrame may be used as just empty containers with predefined dtype but no objects in it:

s = pd.Series([], dtype=bool)
s

>>> Series([], dtype: bool)

But if one somehow overcome this issue, and wants to access each object, for example, in the first row and checks its dtype like something like that:

df = pd.DataFrame({'int': [12, 2], 'dt': [pd.Timestamp('2013-01-02'), pd.Timestamp('2016-10-20')]},
                  index = ['A', 'B'])
for col in df.columns:
    df[col].dtype, 'is_int64 = %s' % isinstance(df.loc['A', col], np.int64)

>>> (dtype('int64'), 'is_int64 = True')
>>> (dtype('<M8[ns]'), 'is_int64 = False')

It will be misleading in the case of mixed type of data in single column:

df2 = pd.DataFrame({'data': [12, pd.Timestamp('2013-01-02')]},
                  index = ['A', 'B'])
for col in df2.columns:
    df2[col].dtype, 'is_int64 = %s' % isinstance(df2.loc['A', col], np.int64)

>>> (dtype('O'), 'is_int64 = False')

And last but not least - this method cannot directly recognize Category dtype. As stated in docs:

Returning a single item from categorical data will also return the value, not a categorical of length “1”.

df['int'] = df['int'].astype('category')
for col in df.columns:
    df[col].dtype, 'is_int64 = %s' % isinstance(df.loc['A', col], np.int64)

>>> (CategoricalDtype(categories=[2, 12], ordered=False), 'is_int64 = True')
>>> (dtype('<M8[ns]'), 'is_int64 = False')

So this method is also almost inapplicable.

3. df.dtype.kind approach.

This method yet may work with empty pd.Series or pd.DataFrames but has another problems.

First - it is unable to differ some dtypes:

df = pd.DataFrame({'prd'  :[pd.Period('2002-03','D'), pd.Period('2012-02-01', 'D')],
                   'str'  :['s1', 's2'],
                   'cat'  :[1, -1]})
df['cat'] = df['cat'].astype('category')
for col in df:
    # kind will define all columns as 'Object'
    print (df[col].dtype, df[col].dtype.kind)

>>> period[D] O
>>> object O
>>> category O

Second, what is actually still unclear for me, it even returns on some dtypes None.

4. df.select_dtypes approach.

This is almost what we want. This method designed inside pandas so it handles most corner cases mentioned earlier - empty DataFrames, differs numpy or pandas-specific dtypes well. It works well with single dtype like .select_dtypes('bool'). It may be used even for selecting groups of columns based on dtype:

test = pd.DataFrame({'bool' :[False, True], 'int64':[-1,2], 'int32':[-1,2],'float': [-2.5, 3.4],
                     'compl':np.array([1-1j, 5]),
                     'dt'   :[pd.Timestamp('2013-01-02'), pd.Timestamp('2016-10-20')],
                     'td'   :[pd.Timestamp('2012-03-02')- pd.Timestamp('2016-10-20'),
                              pd.Timestamp('2010-07-12')- pd.Timestamp('2000-11-10')],
                     'prd'  :[pd.Period('2002-03','D'), pd.Period('2012-02-01', 'D')],
                     'intrv':pd.arrays.IntervalArray([pd.Interval(0, 0.1), pd.Interval(1, 5)]),
                     'str'  :['s1', 's2'],
                     'cat'  :[1, -1],
                     'obj'  :[[1,2,3], [5435,35,-52,14]]
                    })
test['int32'] = test['int32'].astype(np.int32)
test['cat'] = test['cat'].astype('category')

Like so, as stated in the docs:

test.select_dtypes('number')

>>>     int64   int32   float   compl   td
>>> 0      -1      -1   -2.5    (1-1j)  -1693 days
>>> 1       2       2    3.4    (5+0j)   3531 days

On may think that here we see first unexpected (at used to be for me: question) results - TimeDelta is included into output DataFrame. But as answered in contrary it should be so, but one have to be aware of it. Note that bool dtype is skipped, that may be also undesired for someone, but it's due to bool and number are in different "subtrees" of numpy dtypes. In case with bool, we may use test.select_dtypes(['bool']) here.

Next restriction of this method is that for current version of pandas (0.24.2), this code: test.select_dtypes('period') will raise NotImplementedError.

And another thing is that it's unable to differ strings from other objects:

test.select_dtypes('object')

>>>     str     obj
>>> 0    s1     [1, 2, 3]
>>> 1    s2     [5435, 35, -52, 14]

But this is, first - already mentioned in the docs. And second - is not the problem of this method, rather the way strings are stored in DataFrame. But anyway this case have to have some post processing.

5. df.api.types.is_XXX_dtype approach.

This one is intended to be most robust and native way to achieve dtype recognition (path of the module where functions resides says by itself) as i suppose. And it works almost perfectly, but still have at least one caveat and still have to somehow distinguish string columns.

Besides, this may be subjective, but this approach also has more 'human-understandable' number dtypes group processing comparing with .select_dtypes('number'):

for col in test.columns:
    if pd.api.types.is_numeric_dtype(test[col]):
        print (test[col].dtype)

>>> bool
>>> int64
>>> int32
>>> float64
>>> complex128

No timedelta and bool is included. Perfect.

My pipeline exploits exactly this functionality at this moment of time, plus a bit of post hand processing.

Output.

Hope I was able to argument the main point - that all discussed approaches may be used, but only pd.DataFrame.select_dtypes() and pd.api.types.is_XXX_dtype should be really considered as the applicable ones.

Preferred string type in C++ is string, defined in namespace std, in header <string> and you can initialize it like this for example:

#include <string>

int main()
{
   std::string str1("Some text");
   std::string str2 = "Some text";
}

More about it you can find here and here.

What do you think this is supposed to be: ((t[1])/length) * t[1] += string

Python can't parse this, it's a syntax error.

I'm not positive what you're asking, but if you're looking for an example of when one would want to use a null key, I use them often in maps to represent the default case (i.e. the value that should be used if a given key isn't present):

Map<A, B> foo;
A search;
B val = foo.containsKey(search) ? foo.get(search) : foo.get(null);

HashMap handles null keys specially (since it can't call .hashCode() on a null object), but null values aren't anything special, they're stored in the map like anything else

Make sure you use the percent sign in front of variables, not the dollar sign.

It's %{HTTP_HOST}, not ${HTTP_HOST}. There will be nothing in the error_log, there will be no Internal Server Errors, your regexp is still correct, the rule will just not match. This is really hideous if you work with django / genshi templates a lot and have ${} for variable substitution in muscle memory.

Because i can, i thought i should share my solution, since it is a very fascinating problem and it has so many solutions.

It works for nodejs too, if you replace let buffer = new Uint8Array(); crypto.getRandomValues with let buffer = crypto.randomBytes(16)

I hope it helps somebody. It should beat most regex solutions in performance.

const hex = '0123456789ABCDEF'

let generateToken = function() {
    let buffer = new Uint8Array(16)
    
    crypto.getRandomValues(buffer)

    buffer[6] = 0x40 | (buffer[6] & 0xF)
    buffer[8] = 0x80 | (buffer[8] & 0xF)

    let segments = []

    for (let i = 0; i < 16; ++i) {
        segments.push(hex[(buffer[i] >> 4 & 0xF)])
        segments.push(hex[(buffer[i] >> 0 & 0xF)])

        if (i == 3 || i == 5 || i == 7 || i == 9) {
            segments.push('-')
        }
    }

    return segments.join('')
}

for (let i = 0; i < 100; ++i) {
  console.log(generateToken())
}

Performance charts, everybody loves them: jsbench

Have fun and thank you for all the other solutions, some served my quite long.

Or if you are collecting many numbers, use a loop

num = []
for i in xrange(1, 10):
    num.append(raw_input('Enter the %s number: '))

print num

With 'Enter' is better use ReadLine() or Read(2), because key 'Enter' generate 2 symbols. If user enter any text next Pause() also wil be skipped even with Read(2). So ReadLine() is better:

Sub Pause()
    WScript.Echo ("Press Enter to continue")
    z = WScript.StdIn.ReadLine()
End Sub

More examples look in http://technet.microsoft.com/en-us/library/ee156589.aspx

Use Iterator.remove().

In order to rename a table in a different schema, try:

ALTER TABLE owner.mytable RENAME TO othertable;

The rename command (as in "rename mytable to othertable") only supports renaming a table in the same schema.

1)just get your lib from here http://search.maven.org/

2)create a libs folder in app directory

3)paste ur library there

4)right click on ur library and click "Add as Library"

5)thats all u need to do!

I hope this will definitely gonna help you!!!!

Go through each item of the array and sum values to previous values if they exist, if not just assign the value.

<?php
$array = 
[
    [
        'a'=>1,
        'b'=>1,
        'c'=>1,
    ],
    [
        'a'=>2,
        'b'=>2,
    ],
    [
        'a'=>3,
        'd'=>3,
    ]
];

$result = array_reduce($array, function($carry, $item) {
    foreach($item as $k => $v)
        $carry[$k] = $v + ($carry[$k] ?? 0);

    return $carry;
}, []);

print_r($result);

Output:

Array
(
    [a] => 6
    [b] => 3
    [c] => 1
    [d] => 3
)

Or just loop through each sub array, and group the values for each column. Eventually summing them:

foreach($array as $subarray)
    foreach($subarray as $key => $value)
        $grouped[$key][] = $value;

$sums = array_map('array_sum', $grouped);

you'll want to use && to see that it is not equal to "AM" AND not equal to "PM"

if(!TimeOfDayStringQ.equals("AM") && !TimeOfDayStringQ.equals("PM")) {
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to be clear you can also do

if(!(TimeOfDayStringQ.equals("AM") || TimeOfDayStringQ.equals("PM"))){
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to have the not (one or the other) phrase in the code (remember the (silent) brackets)

import java.io.*;
import java.util.*;
public class CandidateCode {
    public static void main(String args[] ) throws Exception {
       Scanner sc = new Scanner(System.in);
           int n =Integer.parseInt(sc.nextLine());
           String arr[] = new String[n];
        for (int i = 0; i < arr.length; i++) {
                arr[i] = sc.nextLine();
                }


         for(int i = 0; i <arr.length; ++i) {
            for (int j = i + 1; j <arr.length; ++j) {
                if (arr[i].compareTo(arr[j]) > 0) {
                    String temp = arr[i];
                    arr[i] = arr[j];
                    arr[j] = temp;
                }
            }
        }
        for(int i = 0; i <arr.length; i++) {
            System.out.println(arr[i]);
        }
   }
}

There are need to be install pip command at first

apt-get install python-pip

So that just install Sequently

apt-get install python-dev libmysqlclient-dev

apt-get install python-pip

pip install MySQL-python

I went threw the same problem. None of the answers above worked for me, but i ended finding the solution on my own. The ipa file wasn't created because there was library files (libXXX.a) in Target-> Build Phases -> Copy Bundle with resources

Hope it will help someone :)

This works:

var img = document.createElement('img');
img.src = 'img/eqp/' + this.apparel + '/' + this.facing + '_idle.png';
document.getElementById('gamediv').appendChild(img)

Or using jQuery:

$('<img/>')
.attr('src','img/eqp/' + this.apparel + '/' + this.facing + '_idle.png')
.appendTo('#gamediv');

It's a pity that both of the answers analyze the problem but didn't give a direct answer. Let's see the code.

Z = np.array([1.0, 1.0, 1.0, 1.0])  

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B
Nlayers = Z.size
N = 3
TempLake = np.zeros((N+1, Nlayers))
kOUT = np.zeros(N + 1)

for i in xrange(N):
    # store the i-th result of
    # function "func" in i-th item in kOUT
    kOUT[i] = func(TempLake[i], Z)

The error shows that you set the ith item of kOUT(dtype:int) into an array. Here every item in kOUT is an int, can't directly assign to another datatype. Hence you should declare the data type of kOUT when you create it. For example, like:

Change the statement below:

kOUT = np.zeros(N + 1)

into:

kOUT = np.zeros(N + 1, dtype=object)

or:

kOUT = np.zeros((N + 1, N + 1))

All code:

import numpy as np
Z = np.array([1.0, 1.0, 1.0, 1.0])

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B

Nlayers = Z.size
N = 3
TempLake = np.zeros((N + 1, Nlayers))

kOUT = np.zeros(N + 1, dtype=object)
for i in xrange(N):
    kOUT[i] = func(TempLake[i], Z)

Hope it can help you.

The WHERE clause is misplaced, it has to follow the table references and JOIN operations.

Something like this:

 FROM tartikel p1 
 JOIN tartikelpict p2 
   ON p1.kArtikel = p2.kArtikel 
  AND p2.nNr = 1
WHERE p1.dErstellt >= DATE(NOW()) - INTERVAL 7 DAY
ORDER BY p1.kArtikel DESC

EDIT (three plus years later)

The above essentially answers the question "I tried to add a WHERE clause to my query and now the query is returning an error, how do I fix it?"

As to a question about writing a condition that checks a date range of "last 7 days"...

That really depends on interpreting the specification, what the datatype of the column in the table is (DATE or DATETIME) and what data is available... what should be returned.

To summarize: the general approach is to identify a "start" for the date/datetime range, and "end" of that range, and reference those in a query. Let's consider something easier... all rows for "yesterday".

If our column is DATE type. Before we incorporate an expression into a query, we can test it in a simple SELECT

 SELECT DATE(NOW()) + INTERVAL -1 DAY 

and verify the result returned is what we expect. Then we can use that same expression in a WHERE clause, comparing it to a DATE column like this:

 WHERE datecol = DATE(NOW()) + INTERVAL -1 DAY

For a DATETIME or TIMESTAMP column, we can use >= and < inequality comparisons to specify a range

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -1 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

For "last 7 days" we need to know if that mean from this point right now, back 7 days ... e.g. the last 7*24 hours , including the time component in the comparison, ...

 WHERE datetimecol >= NOW() + INTERVAL -7 DAY
   AND datetimecol <  NOW() + INTERVAL  0 DAY

the last seven complete days, not including today

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -7 DAY
   AND datetimecol <  DATE(NOW()) + INTERVAL  0 DAY

or past six complete days plus so far today ...

 WHERE datetimecol >= DATE(NOW()) + INTERVAL -6 DAY
   AND datetimecol <  NOW()       + INTERVAL  0 DAY

I recommend testing the expressions on the right side in a SELECT statement, we can use a user-defined variable in place of NOW() for testing, not being tied to what NOW() returns so we can test borders, across week/month/year boundaries, and so on.

SET @clock = '2017-11-17 11:47:47' ;

SELECT DATE(@clock)
     , DATE(@clock) + INTERVAL -7 DAY 
     , @clock + INTERVAL -6 DAY 

Once we have expressions that return values that work for "start" and "end" for our particular use case, what we mean by "last 7 days", we can use those expressions in range comparisons in the WHERE clause.

(Some developers prefer to use the DATE_ADD and DATE_SUB functions in place of the + INTERVAL val DAY/HOUR/MINUTE/MONTH/YEAR syntax.

And MySQL provides some convenient functions for working with DATE, DATETIME and TIMESTAMP datatypes... DATE, LAST_DAY,

Some developers prefer to calculate the start and end in other code, and supply string literals in the SQL query, such that the query submitted to the database is

  WHERE datetimecol >= '2017-11-10 00:00'
    AND datetimecol <  '2017-11-17 00:00'

And that approach works too. (My preference would be to explicitly cast those string literals into DATETIME, either with CAST, CONVERT or just the + INTERVAL trick...

  WHERE datetimecol >= '2017-11-10 00:00' + INTERVAL 0 SECOND
    AND datetimecol <  '2017-11-17 00:00' + INTERVAL 0 SECOND

The above all assumes we are storing "dates" in appropriate DATE, DATETIME and/or TIMESTAMP datatypes, and not storing them as strings in variety of formats e.g. 'dd/mm/yyyy', m/d/yyyy, julian dates, or in sporadically non-canonical formats, or as a number of seconds since the beginning of the epoch, this answer would need to be much longer.

It's called a 'constraint' on the generic parameter T. It means that T must be a reference type (a class) and that it must have a public default constructor.

Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener().

You can see more information about this class here.

It lets you be aware of every scrolling event - but without the coordinates. You can get them by using getScrollY() or getScrollX() from within the listener though.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = rootScrollView.getScrollY(); // For ScrollView
        int scrollX = rootScrollView.getScrollX(); // For HorizontalScrollView
        // DO SOMETHING WITH THE SCROLL COORDINATES
    }
});

// dict is Dictionary<string, Foo>

Foo[] foos = new Foo[dict.Count];
dict.Values.CopyTo(foos, 0);

// or in C# 3.0:
var foos = dict.Values.ToArray();

While your solution should work, it can be difficult to read depending on the skill level of your fellow programmers. Additionally, it moves functionality away from the call site. Which can make maintenance a little more difficult.

I'm not sure if your goal is to get the keys into a vector or print them to cout so I'm doing both. You may try something like this:

std::map<int, int> m;
std::vector<int> key, value;
for(std::map<int,int>::iterator it = m.begin(); it != m.end(); ++it) {
  key.push_back(it->first);
  value.push_back(it->second);
  std::cout << "Key: " << it->first << std::endl();
  std::cout << "Value: " << it->second << std::endl();
}

Or even simpler, if you are using Boost:

map<int,int> m;
pair<int,int> me; // what a map<int, int> is made of
vector<int> v;
BOOST_FOREACH(me, m) {
  v.push_back(me.first);
  cout << me.first << "\n";
}

Personally, I like the BOOST_FOREACH version because there is less typing and it is very explicit about what it is doing.

First, You will need to import sys

sys - System-specific parameters and functions

This module provides access to certain variables used and maintained by the interpreter, and to functions that interact strongly with the interpreter. This module is still available. I will edit this post in case this module is not working anymore.

And then, you can print the numbers of arguments or what you want here, the list of arguments.

Follow the script below :

#!/usr/bin/python

import sys

print 'Number of arguments entered :' len(sys.argv)

print 'Your argument list :' str(sys.argv)

Then, run your python script :

$ python arguments_List.py chocolate milk hot_Chocolate

And you will have the result that you were asking :

Number of arguments entered : 4
Your argument list : ['arguments_List.py', 'chocolate', 'milk', 'hot_Chocolate']

Hope that helped someone.

If you want to skip every other row and every other column, then you can do it with basic slicing:

In [49]: x=np.arange(16).reshape((4,4))
In [50]: x[1:4:2,1:4:2]
Out[50]: 
array([[ 5,  7],
       [13, 15]])

This returns a view, not a copy of your array.

In [51]: y=x[1:4:2,1:4:2]

In [52]: y[0,0]=100

In [53]: x   # <---- Notice x[1,1] has changed
Out[53]: 
array([[  0,   1,   2,   3],
       [  4, 100,   6,   7],
       [  8,   9,  10,  11],
       [ 12,  13,  14,  15]])

while z=x[(1,3),:][:,(1,3)] uses advanced indexing and thus returns a copy:

In [58]: x=np.arange(16).reshape((4,4))
In [59]: z=x[(1,3),:][:,(1,3)]

In [60]: z
Out[60]: 
array([[ 5,  7],
       [13, 15]])

In [61]: z[0,0]=0

Note that x is unchanged:

In [62]: x
Out[62]: 
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11],
       [12, 13, 14, 15]])

If you wish to select arbitrary rows and columns, then you can't use basic slicing. You'll have to use advanced indexing, using something like x[rows,:][:,columns], where rows and columns are sequences. This of course is going to give you a copy, not a view, of your original array. This is as one should expect, since a numpy array uses contiguous memory (with constant strides), and there would be no way to generate a view with arbitrary rows and columns (since that would require non-constant strides).

In my case I resolved this issue by

• clicking button Add which is next to the "Credentials" text
• adding credentials (login and password)
• selecting these credentials on the popup menu, which is on the left of the Add button
• waiting for a couple of seconds

My environment was Jenkins installed in the Windows. The UI question was why the warning was placed before the tool to resolve it.

So here is an other way:

background-image: linear-gradient(rgba(255,255,255,0.5), rgba(255,255,255,0.5)), url("your_image.png");

I had a similar problem where I didn't want to change the Python module search path and needed to load a module relatively from a script (in spite of "scripts can't import relative with all" as BrenBarn explained nicely above).

So I used the following hack. Unfortunately, it relies on the imp module that became deprecated since version 3.4 to be dropped in favour of importlib. (Is this possible with importlib, too? I don't know.) Still, the hack works for now.

Example for accessing members of moduleX in subpackage1 from a script residing in the subpackage2 folder:

#!/usr/bin/env python3

import inspect
import imp
import os

def get_script_dir(follow_symlinks=True):
    """
    Return directory of code defining this very function.
    Should work from a module as well as from a script.
    """
    script_path = inspect.getabsfile(get_script_dir)
    if follow_symlinks:
        script_path = os.path.realpath(script_path)
    return os.path.dirname(script_path)

# loading the module (hack, relying on deprecated imp-module)
PARENT_PATH = os.path.dirname(get_script_dir())
(x_file, x_path, x_desc) = imp.find_module('moduleX', [PARENT_PATH+'/'+'subpackage1'])
module_x = imp.load_module('subpackage1.moduleX', x_file, x_path, x_desc)

# importing a function and a value
function = module_x.my_function
VALUE = module_x.MY_CONST

A cleaner approach seems to be to modify the sys.path used for loading modules as mentioned by Federico.

#!/usr/bin/env python3

if __name__ == '__main__' and __package__ is None:
    from os import sys, path
    # __file__ should be defined in this case
    PARENT_DIR = path.dirname(path.dirname(path.abspath(__file__)))
   sys.path.append(PARENT_DIR)
from subpackage1.moduleX import *

$("<div/>").appendTo("div#main");

will append a blank div to <div id="main"></div>

The easiest approach I know of is using onresize() func:

   window.onresize = function(event) {
        ...
    }

Here is a fiddle for it

You don't need that sort of solution for string literals, since they are concatenated at the language level, and it wouldn't work anyway because "s""1" isn't a valid preprocessor token.

[Edit: In response to the incorrect "Just for the record" comment below that unfortunately received several upvotes, I will reiterate the statement above and observe that the program fragment

#define PPCAT_NX(A, B) A ## B
PPCAT_NX("s", "1")

produces this error message from the preprocessing phase of gcc: error: pasting ""s"" and ""1"" does not give a valid preprocessing token

]

However, for general token pasting, try this:

/*
 * Concatenate preprocessor tokens A and B without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define PPCAT_NX(A, B) A ## B

/*
 * Concatenate preprocessor tokens A and B after macro-expanding them.
 */
#define PPCAT(A, B) PPCAT_NX(A, B)

Then, e.g., both PPCAT_NX(s, 1) and PPCAT(s, 1) produce the identifier s1, unless s is defined as a macro, in which case PPCAT(s, 1) produces <macro value of s>1.

Continuing on the theme are these macros:

/*
 * Turn A into a string literal without expanding macro definitions
 * (however, if invoked from a macro, macro arguments are expanded).
 */
#define STRINGIZE_NX(A) #A

/*
 * Turn A into a string literal after macro-expanding it.
 */
#define STRINGIZE(A) STRINGIZE_NX(A)

Then,

#define T1 s
#define T2 1
STRINGIZE(PPCAT(T1, T2)) // produces "s1"

By contrast,

STRINGIZE(PPCAT_NX(T1, T2)) // produces "T1T2"
STRINGIZE_NX(PPCAT_NX(T1, T2)) // produces "PPCAT_NX(T1, T2)"

#define T1T2 visit the zoo
STRINGIZE(PPCAT_NX(T1, T2)) // produces "visit the zoo"
STRINGIZE_NX(PPCAT(T1, T2)) // produces "PPCAT(T1, T2)"

Well, I just did

brew install mongodb

and followed the instructions that were output to the STDOUT after it finished installing, and that seems to have worked just fine. I guess it kinda works just like make install and overwrites (upgrades) a previous install.

I recently had this issue and all above solutions didn't work for me.

The reason why it works on your simulator but not real devices is probably related to your Development Certificate.

So I revoked my certificate on Apple Developer Portal and request a new one on my computer. Here are the steps:

1. Goto Apple Developer Portal and revoke your old (not working) development certificate.
2. Add iOS App Development Certificate
3. Follow the step on from Apple
4. Download the newly generated certificate and add it (double click) to your Keychain
5. Make sure it is in your XCode Accounts

Then it works!

Hope it helps!
