The answer lies in which constructors the LinkedHashSet uses to construct the base class:

public LinkedHashSet(int initialCapacity, float loadFactor) {
    super(initialCapacity, loadFactor, true);      // <-- boolean dummy argument
}

...

public LinkedHashSet(int initialCapacity) {
    super(initialCapacity, .75f, true);            // <-- boolean dummy argument
}

...

public LinkedHashSet() {
    super(16, .75f, true);                         // <-- boolean dummy argument
}

...

public LinkedHashSet(Collection<? extends E> c) {
    super(Math.max(2*c.size(), 11), .75f, true);   // <-- boolean dummy argument
    addAll(c);
}

And (one example of) a HashSet constructor that takes a boolean argument is described, and looks like this:

/**
 * Constructs a new, empty linked hash set.  (This package private
 * constructor is only used by LinkedHashSet.) The backing
 * HashMap instance is a LinkedHashMap with the specified initial
 * capacity and the specified load factor.
 *
 * @param      initialCapacity   the initial capacity of the hash map
 * @param      loadFactor        the load factor of the hash map
 * @param      dummy             ignored (distinguishes this
 *             constructor from other int, float constructor.)
 * @throws     IllegalArgumentException if the initial capacity is less
 *             than zero, or if the load factor is nonpositive
 */
HashSet(int initialCapacity, float loadFactor, boolean dummy) {
    map = new LinkedHashMap<E,Object>(initialCapacity, loadFactor);
}

Using @bill-shirley answer with a little addition

function str_to_hex($string) {
$hexstr = unpack('H*', $string);
return array_shift($hexstr);
}
function hex_to_str($string) {
return hex2bin("$string");
}

Usage:

  $str = "Go placidly amidst the noise";
  $hexstr = str_to_hex($str);// 476f20706c616369646c7920616d6964737420746865206e6f697365
  $strstr = hex_to_str($str);// Go placidly amidst the noise

Tremendous thanks to ArturZ for pointing me in the right direction on this. I don't have tmpwatch installed on my system so that isn't the cause of the problem in my case. But the end result is the same: The private /tmp that systemd creates is getting removed. Here's what happens:

1. systemd creates a new process via clone() with the CLONE_NEWNS flag to obtain a private namespace. Or maybe it calls unshare() with CLONE_NEWNS. Same thing.

2. systemd creates a subdirectory in /tmp (e.g. /tmp/systemd-namespace-XRiWad/private) and mounts it on /tmp. Because CLONE_NEWNS was set in #1, this mountpoint is invisible to all other processes.

3. systemd then invokes mysqld in this private namespace.

4. Some specific database operations (e.g. "describe ;") create & remove temporary files, which has the side effect of updating the timestamp on /tmp/systemd-namespace-XRiWad/private. Other database operations execute without using /tmp at all.

5. Eventually 10 days go by where even though the database itself remains active, no operations occur that update the timestamp on /tmp/systemd-namespace-XRiWad/private.

6. /bin/systemd-tmpfiles comes along and removes the "old" /tmp/systemd-namespace-XRiWad/private directory, effectively rendering the private /tmp unusable for mysqld while the public /tmp remains available for everything else on the system.

Restarting mysqld works because this starts everything over again at step #1, with a brand new private /tmp directory. However, the problem eventually comes back again. And again.

The simple solution is to configure /bin/systemd-tmpfiles so that it preserves anything in /tmp with the name /tmp/systemd-namespace-*. I did this by creating /etc/tmpfiles.d/privatetmp.conf with the following contents:

x   /tmp/systemd-namespace-*
x   /tmp/systemd-namespace-*/private

Problem solved.

It might be as simple as leveraging the String's length() method:

1. Split the text string in the Strings XML file into as many sub-strings (a seperate strings from Android's point of view) as many you need different styles, so it could be like: str1, str2, str3 (as in your case), which when joined together are the whole single string you use.

2. And then simply follow the "Span" method, just like you presented with your code - but instead of a single string, combine all the substrings merging them into a single one, each with a different custom style.

You still use the numbers, however not directly - they're no more take a hardcoded form (as in your code) now, but they're being substituted with the combined length() methods (note two stars preceding and suffixing the str.length() in place of the absolute number to extuinguish the change):

str.setSpan(new StyleSpan(android.graphics.Typeface.ITALIC), 0, **str.length()**, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

for the first string size, then str.length() + 1, str.length() + str2.length() for the second string size, and so on with all the substrings, instead of e.g. 0,7 or 8,19 and so on...

try this:

patch -p1 < patchfile

To rename a table you can use:

RENAME mytable TO othertable;

or

ALTER TABLE mytable RENAME TO othertable;

or, if owned by another schema:

ALTER TABLE owner.mytable RENAME TO othertable;

Interestingly, ALTER VIEW does not support renaming a view. You can, however:

RENAME myview TO otherview;

The RENAME command works for tables, views, sequences and private synonyms, for your own schema only.

If the view is not in your schema, you can recompile the view with the new name and then drop the old view.

Here's an answer, based on (and I think an improvement on) Tester101's answer, expressed as a subroutine, with the CopyFile line once instead of three times, and prepared to handle changing the file name as the copy is made (no hard-coded destination directory). I also found I had to delete the target file before copying to get this to work, but that might be a Windows 7 thing. The WScript.Echo statements are because I didn't have a debugger and can of course be removed if desired.

Sub CopyFile(SourceFile, DestinationFile)

    Set fso = CreateObject("Scripting.FileSystemObject")

    'Check to see if the file already exists in the destination folder
    Dim wasReadOnly
    wasReadOnly = False
    If fso.FileExists(DestinationFile) Then
        'Check to see if the file is read-only
        If fso.GetFile(DestinationFile).Attributes And 1 Then 
            'The file exists and is read-only.
            WScript.Echo "Removing the read-only attribute"
            'Remove the read-only attribute
            fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes - 1
            wasReadOnly = True
        End If

        WScript.Echo "Deleting the file"
        fso.DeleteFile DestinationFile, True
    End If

    'Copy the file
    WScript.Echo "Copying " & SourceFile & " to " & DestinationFile
    fso.CopyFile SourceFile, DestinationFile, True

    If wasReadOnly Then
        'Reapply the read-only attribute
        fso.GetFile(DestinationFile).Attributes = fso.GetFile(DestinationFile).Attributes + 1
    End If

    Set fso = Nothing

End Sub

The modern way (as of 2020) to add entries to a multimap (a map of lists) in Java is:

map.computeIfAbsent("apple", k -> new ArrayList<>()).add(2);
map.computeIfAbsent("apple", k -> new ArrayList<>()).add(3);

According to Map.computeIfAbsent docs:

If the specified key is not already associated with a value (or is mapped to null), attempts to compute its value using the given mapping function and enters it into this map unless null.

Returns: the current (existing or computed) value associated with the specified key, or null if the computed value is null

The most idiomatic way to iterate a map of lists is using Map.forEach and Iterable.forEach:

map.forEach((k, l) -> l.forEach(v -> /* use k and v here */));

Or, as shown in other answers, a traditional for loop:

for (Map.Entry<String, List<Integer>> e : map.entrySet()) {
    String k = e.getKey();
    for (Integer v : e.getValue()) {
        /* use k and v here */
    }
}

Here is a sample with full error handling and supporting charset specification for pre-Java 7. With Java 7 you can use try-with-resources syntax, which makes the code cleaner.

If you just want the default charset you can skip the InputStream and use FileReader.

InputStream ins = null; // raw byte-stream
Reader r = null; // cooked reader
BufferedReader br = null; // buffered for readLine()
try {
    String s;
    ins = new FileInputStream("textfile.txt");
    r = new InputStreamReader(ins, "UTF-8"); // leave charset out for default
    br = new BufferedReader(r);
    while ((s = br.readLine()) != null) {
        System.out.println(s);
    }
}
catch (Exception e)
{
    System.err.println(e.getMessage()); // handle exception
}
finally {
    if (br != null) { try { br.close(); } catch(Throwable t) { /* ensure close happens */ } }
    if (r != null) { try { r.close(); } catch(Throwable t) { /* ensure close happens */ } }
    if (ins != null) { try { ins.close(); } catch(Throwable t) { /* ensure close happens */ } }
}

Here is the Groovy version, with full error handling:

File f = new File("textfile.txt");
f.withReader("UTF-8") { br ->
    br.eachLine { line ->
        println line;
    }
}

Explained by Red Hat:

Cache Pages:

A cache is the part of the memory which transparently stores data so that future requests for that data can be served faster. This memory is utilized by the kernel to cache disk data and improve i/o performance.

The Linux kernel is built in such a way that it will use as much RAM as it can to cache information from your local and remote filesystems and disks. As the time passes over various reads and writes are performed on the system, kernel tries to keep data stored in the memory for the various processes which are running on the system or the data that of relevant processes which would be used in the near future. The cache is not reclaimed at the time when process get stop/exit, however when the other processes requires more memory then the free available memory, kernel will run heuristics to reclaim the memory by storing the cache data and allocating that memory to new process.

When any kind of file/data is requested then the kernel will look for a copy of the part of the file the user is acting on, and, if no such copy exists, it will allocate one new page of cache memory and fill it with the appropriate contents read out from the disk.

The data that is stored within a cache might be values that have been computed earlier or duplicates of original values that are stored elsewhere in the disk. When some data is requested, the cache is first checked to see whether it contains that data. The data can be retrieved more quickly from the cache than from its source origin.

SysV shared memory segments are also accounted as a cache, though they do not represent any data on the disks. One can check the size of the shared memory segments using ipcs -m command and checking the bytes column.

Buffers:

Buffers are the disk block representation of the data that is stored under the page caches. Buffers contains the metadata of the files/data which resides under the page cache. Example: When there is a request of any data which is present in the page cache, first the kernel checks the data in the buffers which contain the metadata which points to the actual files/data contained in the page caches. Once from the metadata the actual block address of the file is known, it is picked up by the kernel for processing.

the disabled attributes value is actally not considered.. usually if you have noticed the attribute is set as disabled="disabled" the "disabled" here is not necessary persay.. thus the best thing to do is to remove the attribute.

element.removeAttribute("disabled");     

also you could do

element.disabled=false;

You can use the following snippet:

  tr td:first-child {text-decoration: underline;}
  tr td:last-child {color: red;}

Using the following pseudo classes:

:first-child means "select this element if it is the first child of its parent".

:last-child means "select this element if it is the last child of its parent".

Only element nodes (HTML tags) are affected, these pseudo-classes ignore text nodes.

Yes it possible to have constructor in structure here is one example:

#include<iostream.h> 
struct a {
  int x;
  a(){x=100;}
};

int main() {
  struct a a1;
  getch();
}

I have a slightly different perspective on the difference between a DATETIME and a TIMESTAMP. A DATETIME stores a literal value of a date and time with no reference to any particular timezone. So, I can set a DATETIME column to a value such as '2019-01-16 12:15:00' to indicate precisely when my last birthday occurred. Was this Eastern Standard Time? Pacific Standard Time? Who knows? Where the current session time zone of the server comes into play occurs when you set a DATETIME column to some value such as NOW(). The value stored will be the current date and time using the current session time zone in effect. But once a DATETIME column has been set, it will display the same regardless of what the current session time zone is.

A TIMESTAMP column on the other hand takes the '2019-01-16 12:15:00' value you are setting into it and interprets it in the current session time zone to compute an internal representation relative to 1/1/1970 00:00:00 UTC. When the column is displayed, it will be converted back for display based on whatever the current session time zone is. It's a useful fiction to think of a TIMESTAMP as taking the value you are setting and converting it from the current session time zone to UTC for storing and then converting it back to the current session time zone for displaying.

If my server is in San Francisco but I am running an event in New York that starts on 9/1/1029 at 20:00, I would use a TIMESTAMP column for holding the start time, set the session time zone to 'America/New York' and set the start time to '2009-09-01 20:00:00'. If I want to know whether the event has occurred or not, regardless of the current session time zone setting I can compare the start time with NOW(). Of course, for displaying in a meaningful way to a perspective customer, I would need to set the correct session time zone. If I did not need to do time comparisons, then I would probably be better off just using a DATETIME column, which will display correctly (with an implied EST time zone) regardless of what the current session time zone is.

TIMESTAMP LIMITATION

The TIMESTAMP type has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC and so it may not usable for your particular application. In that case you will have to use a DATETIME type. You will, of course, always have to be concerned that the current session time zone is set properly whenever you are using this type with date functions such as NOW().

Had exactly the same problem as UseR (original question), I'm also using windows 7. I tried all proposed solutions and they didn't work.

I resolved the problem doing as follows:

1. Using RStudio instead of R console.

2. Actualising the version of R (from 3.1.0 to 3.1.1) so that the library RCurl runs OK on it. (I'm using now R3.1.1 32bit although my system is 64bit).

3. I typed the URL address as https (secure connection) and with / instead of backslashes \\.

4. Setting method = "auto".

It works for me now. You should see the message:

Content type 'text/csv; charset=utf-8' length 9294 bytes
opened URL
downloaded 9294 by

I suggest you put this code into a method and create a unit test.

public static boolean isLeapYear(int year) {
    assert year >= 1583; // not valid before this date.
    return ((year % 4 == 0) && (year % 100 != 0)) || (year % 400 == 0);
}

In the unit test

assertTrue(isLeapYear(2000));
assertTrue(isLeapYear(1904));
assertFalse(isLeapYear(1900));
assertFalse(isLeapYear(1901));

With Project JUnion you can use structs in Java by annotating a class with @Struct annotation

@Struct
class Member {
  string FirstName; 
  string LastName;  
  int BirthYear; 
}

More info at the project's website: https://tehleo.github.io/junion/

The error message says it all. At runtime, the type is gone, there is no way to check for it.

You could catch it by making a factory for your object like this:

 public static <T> MyObject<T> createMyObject(Class<T> type) {
    return new MyObject<T>(type);
 }

And then in the object's constructor store that type, so variable so that your method could look like this:

        if (arg0 != null && !(this.type.isAssignableFrom(arg0.getClass()))
        {
            return -1;
        }

for i in ('apple', 'banana', 'carrot'):
    fruitdict[i] = locals()[i]

I am facing a strange behavior.

SELECT INTO and SET Both works for some variables and not for others. Event syntaxes are the same

SET @Invoice_UserId :=  (SELECT UserId FROM invoice WHERE InvoiceId = @Invoice_Id  LIMIT 1); -- Working
                SET @myamount := (SELECT amount FROM invoice WHERE InvoiceId = @Invoice_Id LIMIT 1); - Not working
SELECT  Amount INTO @myamount FROM invoice WHERE InvoiceId = 29  LIMIT 1; - Not working

If I run these queries directly then works, but not working in stored procedure.

Have you looked at angular-ui bootstrap? There's a Dialog (ui.bootstrap.dialog) directive that works quite well. You can close the dialog during the call back the angular way (per the example):

$scope.close = function(result){
  dialog.close(result);
};

Update:

The directive has since been renamed Modal.

As joe mentioned, creating the shell script and then creating an applescript script to call the shell script, will accomplish this, and is quite handy.

Shell Script

1. Create your shell script in your favorite text editor, for example:

   mono "/Volumes/Media/~Users/me/Software/keepass/keepass.exe"

   (this runs the w32 executable, using the mono framework)

2. Save shell script, for my example "StartKeepass.sh"

Apple Script

1. Open AppleScript Editor, and call the shell script

   do shell script "sh /Volumes/Media/~Users/me/Software/StartKeepass.sh" user name "<enter username here>" password "<Enter password here>" with administrator privileges

   • do shell script - applescript command to call external shell commands
   • "sh ...." - this is your shell script (full path) created in step one (you can also run direct commands, I could omit the shell script and just run my mono command here)
   • user name - declares to applescript you want to run the command as a specific user
   • "<enter username here> - replace with your username (keeping quotes) ex "josh"
   • password - declares to applescript your password
   • "<enter password here>" - replace with your password (keeping quotes) ex "mypass"
   • with administrative privileges - declares you want to run as an admin

Create Your .APP

1. save your applescript as filename.scpt, in my case RunKeepass.scpt

2. save as... your applescript and change the file format to application, resulting in RunKeepass.app in my case

3. Copy your app file to your apps folder

Using a form in a view pretty much explains it.

The standard pattern for processing a form in a view looks like this:

def contact(request):
    if request.method == 'POST': # If the form has been submitted...
        form = ContactForm(request.POST) # A form bound to the POST data
        if form.is_valid(): # All validation rules pass
            # Process the data in form.cleaned_data
            # ...

            print form.cleaned_data['my_form_field_name']

            return HttpResponseRedirect('/thanks/') # Redirect after POST
    else:
        form = ContactForm() # An unbound form

    return render_to_response('contact.html', {
        'form': form,
    })

Try passing width=200 as additional paramater when creating the Label.

This should work in creating label with specified width.

If you want to change it later, you can use:

label.config(width=200)

As you want to change the size of font itself you can try:

label.config(font=("Courier", 44))

Microsoft® SQL Server™ 2000 uses these SQL-92 keywords for outer joins specified in a FROM clause:

• LEFT OUTER JOIN or LEFT JOIN

• RIGHT OUTER JOIN or RIGHT JOIN

• FULL OUTER JOIN or FULL JOIN

From MSDN

The full outer join or full join returns all rows from both tables, matching up the rows wherever a match can be made and placing NULLs in the places where no matching row exists.

This is a example for get the url image, escape the p tag from some item.

Try this:

$('#img').attr('src').split('<p>')[1].split('</p>')[0]

This is an issue relating JRE.In my case (eclipse Luna with Maven plugin, JDK 7) I solved this by making following change in pom.xml and then Maven Update Project.

from:

 <configuration>
        <source>1.8</source>
        <target>1.8</target>
</configuration>

to:

 <configuration>
        <source>1.7</source>
        <target>1.7</target>
</configuration>

Screenshot showing problem in JRE:

String str1="this is a string";
String str2=str1.clone();

How about copy like this? I think to get a new copy is better, so that the data of str1 won't be affected when str2 is reference and modified in futher action.

Windows Firewall could cause this exception, try to disable it or add a rule for port or even program (java)

        }
        else

            _direction = 'up';
        }
        _top = _cur_top;
        console.log(_direction);

All answers here are still using the FormData API. It is like a "multipart/form-data" upload without a form. You can also upload the file directly as content inside the body of the POST request using xmlHttpRequest like this:

var xmlHttpRequest = new XMLHttpRequest();

var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...

xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);

Content-Type and Content-Disposition headers are used for explaining what we are sending (mime-type and file name).

I posted similar answer also here.

There's no way you can do that changing only that line. You can do:

a = [1]
b = a
a[0] = 2
b[0]

That creates a list, assigns the reference to a, then b also, uses the a reference to set the first element to 2, then accesses using the b reference variable.

Element.innerHTML is pretty much the way to go. Here are a few ways to use it:

HTML

<div class="results"></div>

JavaScript

// 'Modern' browsers (IE8+, use CSS-style selectors)
document.querySelector('.results').innerHTML = 'Hello World!';

// Using the jQuery library
$('.results').html('Hello World!');

If you just want to update a portion of a <div> I usually just add an empty element with a class like value or one I want to replace the contents of to the main <div>. e.g.

<div class="content">Hello <span class='value'></span></div>

Then I'd use some code like this:

// 'Modern' browsers (IE8+, use CSS-style selectors)
document.querySelector('.content .value').innerHTML = 'World!';

// Using the jQuery library
$(".content .value").html("World!");

Then the HTML/DOM would now contain:

<div class="content">Hello <span class='value'>World!</span></div>

The accepted answer is short and sweet, but here is an alternate syntax allowing to provide a separator in Python 3.x.

print(*3*('-',), sep='_')

Something like

select *

 where regexp_like( col1, '[^[:alpha:]]' ) ;

should work

SQL> create table foo( col1 varchar2(100) );

SQL> insert into foo values( 'abc' );

1 row created.

SQL> insert into foo values( 'abc123' );

1 row created.

SQL> insert into foo values( 'def' );

1 row created.

SQL> select *

I repeatedly had the same challenge sometime ago. This problem occurs mostly when you are trying to pull from the remote repository and you have some files on your local instance conflicting with the remote version, if you are using git from an IDE such as IntelliJ, you will be prompted and allowed to make a choice if you want to retain your own changes or you prefer the changes in the remote version to overwrite yours'. If you don't make any choice then you fall into this conflict. all you need to do is run:

git merge --abort # The unresolved conflict will be cleared off

And you can continue what you were doing before the break.

You can create config once and use it everywhere.

In fact in the last answer String strAsciiTab = Character.toString((char) iAsciiValue); the essential part is (char)iAsciiValue which is doing the job (Character.toString useless)

Meaning the first answer was correct actually char ch = (char) yourInt;

if in yourint=49 (or 0x31), ch will be '1'

Button butt= new Button(_context);

To use file_get_contents() over/through a proxy that doesn't require authentication, something like this should do :

(I'm not able to test this one : my proxy requires an authentication)

$aContext = array(
    'http' => array(
        'proxy'           => 'tcp://192.168.0.2:3128',
        'request_fulluri' => true,
    ),
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("http://www.google.com", False, $cxContext);

echo $sFile;

Of course, replacing the IP and port of my proxy by those which are OK for yours ;-)

If you're getting that kind of error :

Warning: file_get_contents(http://www.google.com) [function.file-get-contents]: failed to open stream: HTTP request failed! HTTP/1.0 407 Proxy Authentication Required

It means your proxy requires an authentication.

If the proxy requires an authentication, you'll have to add a couple of lines, like this :

$auth = base64_encode('LOGIN:PASSWORD');

$aContext = array(
    'http' => array(
        'proxy'           => 'tcp://192.168.0.2:3128',
        'request_fulluri' => true,
        'header'          => "Proxy-Authorization: Basic $auth",
    ),
);
$cxContext = stream_context_create($aContext);

$sFile = file_get_contents("http://www.google.com", False, $cxContext);

echo $sFile;

Same thing about IP and port, and, this time, also LOGIN and PASSWORD ;-) Check out all valid http options.

Now, you are passing an Proxy-Authorization header to the proxy, containing your login and password.

And... The page should be displayed ;-)

So you just have to do this right?:

@echo off
echo text shizzle
echo.
echo pause^>nul (press enter)
pause>nul

REM writing to file
(
echo XD
echo LOL
)>settings.cdb
cls

REM setting the variables out of the file
(
set /p input=
set /p input2=
)<settings.cdb
cls

REM echo'ing the variables
echo variables:
echo %input%
echo %input2%
pause>nul

if %input%==XD goto newecho
DEL settings.cdb
exit

:newecho
cls
echo If you can see this, good job!
DEL settings.cdb
pause>nul
exit

I have seen a negative elapsed time reported from using System.nanoTime(). To be clear, the code in question is:

    long startNanos = System.nanoTime();

    Object returnValue = joinPoint.proceed();

    long elapsedNanos = System.nanoTime() - startNanos;

and variable 'elapsedNanos' had a negative value. (I'm positive that the intermediate call took less than 293 years as well, which is the overflow point for nanos stored in longs :)

This occurred using an IBM v1.5 JRE 64bit on IBM P690 (multi-core) hardware running AIX. I've only seen this error occur once, so it seems extremely rare. I do not know the cause - is it a hardware-specific issue, a JVM defect - I don't know. I also don't know the implications for the accuracy of nanoTime() in general.

To answer the original question, I don't think nanoTime is useless - it provides sub-millisecond timing, but there is an actual (not just theoretical) risk of it being inaccurate which you need to take into account.

TL;DR:

print(yourstring.encode('ascii','replace'));

I ran into this myself, working on a Twitch chat (IRC) bot. (Python 2.7 latest)

I wanted to parse chat messages in order to respond...

msg = s.recv(1024).decode("utf-8")

but also print them safely to the console in a human-readable format:

print(msg.encode('ascii','replace'));

This corrected the issue of the bot throwing UnicodeEncodeError: 'charmap' errors and replaced the unicode characters with ?.

This worked for me,

CREATE TABLE newtable LIKE oldtable;

Replicates newtable with old table

INSERT newtable SELECT * FROM oldtable;

Copies all the row data to new table.

Thank you

Another approach is keep that element, change the text, then append that element back

const star_icon = $(li).find('.stars svg')
$(li).find('.stars').text(repo.stargazers_count).append(star_icon)

The net/http api can be tough to use.

require "net/http"

uri = URI.parse(uri)

Net::HTTP.new(uri.host, uri.port).start do |client|
  request                 = Net::HTTP::Post.new(uri.path)
  request.body            = "{}"
  request["Content-Type"] = "application/json"
  client.request(request)
end

You mean like

$target.hide('slow')

?

I was also trying to understand ABI and JesperE’s answer was very helpful.

From a very simple perspective, we may try to understand ABI by considering binary compatibility.

KDE wiki defines a library as binary compatible “if a program linked dynamically to a former version of the library continues running with newer versions of the library without the need to recompile.” For more on dynamic linking, refer Static linking vs dynamic linking

Now, let’s try to look at just the most basic aspects needed for a library to be binary compatibility (assuming there are no source code changes to the library):

1. Same/backward compatible instruction set architecture (processor instructions, register file structure, stack organization, memory access types, along with sizes, layout, and alignment of basic data types the processor can directly access)
2. Same calling conventions
3. Same name mangling convention (this might be needed if say a Fortran program needs to call some C++ library function).

Sure, there are many other details but this is mostly what the ABI also covers.

More specifically to answer your question, from the above, we can deduce:

ABI functionality: binary compatibility

existing entities: existing program/libraries/OS

consumer: libraries, OS

Hope this helps!

Recently faced a problem with fetching 'Origin' request header, then I found this question. But pretty confused with the results, req.get('host') is deprecated, that's why giving Undefined. Use,

    req.header('Origin');
    req.header('Host');
    // this method can be used to access other request headers like, 'Referer', 'User-Agent' etc.

Use :checkbox selector:

$(':checkbox').change(function() {

        // do stuff here. It will fire on any checkbox change

});

I think autocomplete=off is supported in HTML 5.

Ask yourself why you want to do this though - it may make sense in some situations but don't do it just for the sake of doing it.

It's less convenient for users and not even a security issue in OS X (mentioned by Soren below). If you're worried about people having their passwords stolen remotely - a keystroke logger could still do it even though your app uses autcomplete=off.

As a user who chooses to have a browser remember (most of) my information, I'd find it annoying if your site didn't remember mine.

Inside your makefile:

target:
    if test -d dir; then echo "hello world!"; else mkdir dir; fi

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron. Hence, do install it with:

yum install vixie-cron

And then start it with:

service crond start

To make it persistent, so that it starts on boot, use:

chkconfig crond on

On CentOS 7 you need to use cronie:

yum install cronie

On CentOS 6 you can install vixie-cron, but the real package is cronie:

yum install vixie-cron

and

yum install cronie

In both cases you get the same output:

With SQL Server 2016, there is now built-in support for time zones with the AT TIME ZONE statement. You can chain these to do conversions:

SELECT YourOriginalDateTime AT TIME ZONE 'Pacific Standard Time' AT TIME ZONE 'UTC'

Or, this would work as well:

SELECT SWITCHOFFSET(YourOriginalDateTime AT TIME ZONE 'Pacific Standard Time', '+00:00')

Either of these will interpret the input in Pacific time, properly account for whether or not DST is in effect, and then convert to UTC. The result will be a datetimeoffset with a zero offset.

More examples in the CTP announcement.

You can also by jquery:

$('#foo')[0].disabled = true;

Working example:

$('#foo')[0].disabled = true;

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<input id="foo" placeholder="placeholder" value="value" />

Using a single sed

echo "/var/cpanel/users/joebloggs:DNS9=domain.com" | sed 's/.*\/\(.*\):.*/\1/'

Use insert method from range, for example

Sub InsertColumn()
        Columns("C:C").Insert Shift:=xlToRight, CopyOrigin:=xlFormatFromLeftOrAbove
        Range("C1").Value = "Loc"
End Sub

With attribute selector we target input type text in CSS

input[type=text] {
background:gold;
font-size:15px;
 }

Internal error is due to a HIDDEN character at end of shebang line !! ie line #!/usr/bin/perl

By adding - or -w at end moves the character away from "perl" allowing the path to the perl processor to be found and script to execute.

HIDDEN character is created by the editor used to create the script

My problem was solved by uhlocking the screen rotation on my android the app which was causing me a problem now works perfectly

You can find all the details here:

• IDEA-170117 "objc: Class JavaLaunchHelper is implemented in both ..." warning in Run consoles

It's the old bug in Java on Mac that got triggered by the Java Agent being used by the IDE when starting the app. This message is harmless and is safe to ignore. Oracle developer's comment:

The message is benign, there is no negative impact from this problem since both copies of that class are identical (compiled from the exact same source). It is purely a cosmetic issue.

The problem is fixed in Java 9 and in Java 8 update 152.

If it annoys you or affects your apps in any way (it shouldn't), the workaround for IntelliJ IDEA is to disable idea_rt launcher agent by adding idea.no.launcher=true into idea.properties (Help | Edit Custom Properties...). The workaround will take effect on the next restart of the IDE.

I don't recommend disabling IntelliJ IDEA launcher agent, though. It's used for such features as graceful shutdown (Exit button), thread dumps, workarounds a problem with too long command line exceeding OS limits, etc. Losing these features just for the sake of hiding the harmless message is probably not worth it, but it's up to you.

The best way to get the text value from a <label> element is as follows.

if you will be getting element ids frequently it's best to have a function to return the ids:

function id(e){return document.getElementById(e)}

Assume the following structure: <label for='phone'>Phone number</label> <input type='text' id='phone' placeholder='Mobile or landline numbers...'>

This code will extract the text value 'Phone number' from the<label>: var text = id('phone').previousElementSibling.innerHTML;

This code works on all browsers, and you don't have to give each<label>element a unique id.

These are all nice but seq is supposedly deprecated and most only work with numeric ranges.

If you enclose your for loop in double quotes, the start and end variables will be dereferenced when you echo the string, and you can ship the string right back to BASH for execution. $i needs to be escaped with \'s so it is NOT evaluated before being sent to the subshell.

RANGE_START=a
RANGE_END=z
echo -e "for i in {$RANGE_START..$RANGE_END}; do echo \\${i}; done" | bash

This output can also be assigned to a variable:

VAR=`echo -e "for i in {$RANGE_START..$RANGE_END}; do echo \\${i}; done" | bash`

The only "overhead" this should generate should be the second instance of bash so it should be suitable for intensive operations.

According to the widget's page, it should be:

var myDropDownListValues = $("#myDropDownList").multiselect("getChecked").map(function()
{
    return this.value;    
}).get();

It works for me :)

Actually, it is worth noticing that git merge --abort is only equivalent to git reset --merge given that MERGE_HEAD is present. This can be read in the git help for merge command.

git merge --abort # is equivalent to git reset --merge when MERGE_HEAD is present.

After a failed merge, when there is no MERGE_HEAD, the failed merge can be undone with git reset --merge but not necessarily with git merge --abort, so they are not only old and new syntax for the same thing.

Personally I find git reset --merge much more useful in everyday work.

Since you're not using JSON as the data type no your AJAX call, I would assume that you can't access the value because the PHP you gave will only ever be true or false. isset is a function to check if something exists and has a value, not to get access to the value.

Change your PHP to be:

$uid = (isset($_POST['userID'])) ? $_POST['userID'] : 0;

The above line will check to see if the post variable exists. If it does exist it will set $uid to equal the posted value. If it does not exist then it will set $uid equal to 0.

Later in your code you can check the value of $uid and react accordingly

if($uid==0) {
    echo 'User ID not found';
}

This will make your code more readable and also follow what I consider to be best practices for handling data in PHP.

This is not valid TypeScript code. You can not have method invocations in the body of a class.

// INVALID CODE
export class AppComponent {
  public n: number = 1;
  setTimeout(function() {
    n = n + 10;
  }, 1000);
}

Instead move the setTimeout call to the constructor of the class. Additionally, use the arrow function => to gain access to this.

export class AppComponent {
  public n: number = 1;

  constructor() {
    setTimeout(() => {
      this.n = this.n + 10;
    }, 1000);
  }

}

In TypeScript, you can only refer to class properties or methods via this. That's why the arrow function => is important.

In my case no shell was supported in container except sh. So, this worked like a charm

docker exec -it <container-name> sh

You could try using the setTimeout method to make sure your html loads first.

You might want to have look at simple command line scheduler "at":

C:\Documents and Settings\mahendra.patil>at/?

The AT command schedules commands and programs to run on a computer at a specified time and date. The Schedule service must be running to use the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\computername Specifies a remote computer. Commands are scheduled on the local computer if this parameter is omitted.

id Is an identification number assigned to a scheduled command.

/delete Cancels a scheduled command. If id is omitted, all the scheduled commands on the computer are canceled.

/yes Used with cancel all jobs command when no further confirmation is desired.

time Specifies the time when command is to run.

/interactive Allows the job to interact with the desktop of the user who is logged on at the time the job runs.

/every:date[,...] Runs the command on each specified day(s) of the week or month. If date is omitted, the current day of the month is assumed.

/next:date[,...] Runs the specified command on the next occurrence of the day (for example, next Thursday). If date is omitted, the current day of the month is assumed.

"command" Is the Windows NT command, or batch program to be run.

I wanted a profile picture of size 96x96 with data from api. The following solution worked for me in project Angular 7.

.ts:

  @Input() profile;

.html:

 <span class="avatar" [ngStyle]="{'background-image': 'url('+ profile?.public_picture +')'}"></span>

.scss:

 .avatar {
      border-radius: 100%;
      background-size: cover;
      background-position: center center;
      background-repeat: no-repeat;
      width: 96px;
      height: 96px;
    }

Please note that if you write background instead of 'background-image' in [ngStyle], the styles you write (even in style of element) for other background properties like background-position/size, etc. won't work. Because you will already fix it's properties with background: 'url(+ property +) (no providers for size, position, etc. !)'. The [ngStyle] priority is higher than style of element. In background here, only url() property will work. Be sure to use 'background-image' instead of 'background'in case you want to write more properties to background image.

Do not use some of the answers above.

Some suggest the use of nested SELECT, don't do that, it is excruciatingly slow. If you have lots of records to update, use join, so something like:

update (select bonus 
        from employee_bonus b 
        inner join employees e on b.employee_id = e.employee_id 
        where e.bonus_eligible = 'N') t
set t.bonus = 0;

See this link for more details. http://geekswithblogs.net/WillSmith/archive/2008/06/18/oracle-update-with-join-again.aspx.

Also, ensure that there are primary keys on all the tables you are joining.

So I was trying to root one of my old phones and process required Android SDK. When I searched Android SDK, all i could do was download and install Android Studio. Everything went fine and smooth, till I tried to look for SDK in installation. I could not find it under Android Studio installation. But after a little search on Google and Android Studio configuration on my computer, I was able to find it at

        C:\Users\username\Android\sdk

I hope that helps.

Onur Güzel provides the solution in his blog post, "Uninstall Python Package from OS X.

You should type the following commands into the terminal:

1. sudo rm -rf /Library/Frameworks/Python.framework

2. cd /usr/local/bin

3. ls -l . | grep '../Library/Frameworks/Python.framework' | awk '{print $9}' | xargs sudo rm

4. sudo rm -rf "/Applications/Python x.y"

   where command x.y is the version of Python installed. According to your question, it should be 2.7.

In Onur's words:

WARNING: This commands will remove all Python versions installed with packages. Python provided from the system will not be affected.

If you have more than 1 Python version installed from python.org, then run the fourth command again, changing "x.y" for each version of Python that is to be uninstalled.

I had the same problem. It was because I had accidentally used a relative path with the symbolic link.

Are you sure you used full paths, e.g.:

ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/example.com.conf

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

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

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

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

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

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

I recently made an example of how to use events in c#, and posted it on my blog. I tried to make it as clear as possible, with a very simple example. In case it might help anyone, here it is: http://www.konsfik.com/using-events-in-csharp/

It includes description and source code (with lots of comments), and it mainly focuses on a proper (template - like) usage of events and event handlers.

Some key points are:

• Events are like "sub - types of delegates", only more constrained (in a good way). In fact an event's declaration always includes a delegate (EventHandlers are a type of delegate).

• Event Handlers are specific types of delegates (you may think of them as a template), which force the user to create events which have a specific "signature". The signature is of the format: (object sender, EventArgs eventarguments).

• You may create your own sub-class of EventArgs, in order to include any type of information the event needs to convey. It is not necessary to use EventHandlers when using events. You may completely skip them and use your own kind of delegate in their place.

• One key difference between using events and delegates, is that events can only be invoked from within the class that they were declared in, even though they may be declared as public. This is a very important distinction, because it allows your events to be exposed so that they are "connected" to external methods, while at the same time they are protected from "external misuse".

Because I can not comment to @Michelle 's answer, I post my trick here.

Instead of checking the version on meta tag that usually is removed by a customized theme.

Check the rss feed by append /feed to almost any link from that site, then search for some keywords (wordpress, generator), you will have a better chance.

I bet you have to install libxml2-devel or libxml++-devel or even python-devel. But it is only a wild guess, not seeing the actual error from the log file. But it seems gcc is missing either a header file or a library file.

I think the answer depends on which features of stored procedures you need to use.

Stored procedures returning a result set can be run using Query; stored procedures which don't return a result set can be run using Execute - in both cases (using EXEC <procname>) as the SQL command (plus input parameters as necessary). See the documentation for more details.

As of revision 2d128ccdc9a2 there doesn't appear to be native support for OUTPUT parameters; you could add this, or alternatively construct a more complex Query command which declared TSQL variables, executed the SP collecting OUTPUT parameters into the local variables and finallyreturned them in a result set:

DECLARE @output int

EXEC <some stored proc> @i = @output OUTPUT

SELECT @output AS output1

We are using Response.SetCookie() for update the old one cookies and Response.Cookies.Add() are use to add the new cookies. Here below code CompanyId is update in old cookie[OldCookieName].

HttpCookie cookie = Request.Cookies["OldCookieName"];//Get the existing cookie by cookie name.
cookie.Values["CompanyID"] = Convert.ToString(CompanyId);
Response.SetCookie(cookie); //SetCookie() is used for update the cookie.
Response.Cookies.Add(cookie); //The Cookie.Add() used for Add the cookie.

If you have added appCompat Library and also have given proper reference of appCompat from SDK location, try "invalidate caches/Restart".
You can find it from "File" menu in Android Studio.

Yes regex can certainly be used to extract part of a string. Unfortunately different flavours of *nix and different tools use slightly different Regex variants.

This sed command should work on most flavours (Tested on OS/X and Redhat)

echo '12 BBQ ,45 rofl, 89 lol' | sed  's/^.*,\([0-9][0-9]*\).*$/\1/g'

all of these steered me to the correct result, but I wound up doing

<key>NSAppTransportSecurity</key>

      <key>NSAllowsArbitraryLoads</key><true/>  
 </dict>

But this is not recommended at all. The server should have the SSL certificates and so that there is no privacy leaks.

The Rope container may be worth if have to insert/delete string into the random place of destination string or for a long char sequences. Here is an example from SGI's implementation:

crope r(1000000, 'x');          // crope is rope<char>. wrope is rope<wchar_t>
                                // Builds a rope containing a million 'x's.
                                // Takes much less than a MB, since the
                                // different pieces are shared.
crope r2 = r + "abc" + r;       // concatenation; takes on the order of 100s
                                // of machine instructions; fast
crope r3 = r2.substr(1000000, 3);       // yields "abc"; fast.
crope r4 = r2.substr(1000000, 1000000); // also fast.
reverse(r2.mutable_begin(), r2.mutable_end());
                                // correct, but slow; may take a
                                // minute or more.

Instead of using map, I'd recommend using a generator expression with the capability of join to accept an iterator:

def get_nice_string(list_or_iterator):
    return "[" + ", ".join( str(x) for x in list_or_iterator) + "]"

Here, join is a member function of the string class str. It takes one argument: a list (or iterator) of strings, then returns a new string with all of the elements concatenated by, in this case, ,.

There is not really any other way in JavaScript to concatenate strings.
You could theoretically use .concat(), but that's way slower than just +

Libraries are more often than not slower than native JavaScript, especially on basic operations like string concatenation, or numerical operations.

Simply put: + is the fastest.

I started out naming enums in the plural but have since changed to singular. Just seems to make more sense in the context of where they're used.

enum Status { Unknown = 0, Incomplete, Ready }

Status myStatus = Status.Ready;

Compare to:

Statuses myStatus = Statuses.Ready;

I find the singular form to sound more natural in context. We are in agreement that when declaring the enum, which happens in one place, we're thinking "this is a group of whatevers", but when using it, presumably in many places, that we're thinking "this is one whatever".

You can create a folder with os.makedirs()
and use os.path.exists() to see if it already exists:

newpath = r'C:\Program Files\arbitrary' 
if not os.path.exists(newpath):
    os.makedirs(newpath)

If you're trying to take advantage of polymorphic behavior, you need to ensure that the methods visible to outside classes (that need polymorphism) have the same signature. That means they need to have the same name, number and order of parameters, as well as the parameter types.

In your case, you might do better to have a generic draw() method, and rely on the subclasses (Rectangle, Ellipse) to implement the draw() method as what you had been thinking of as "drawEllipse" and "drawRectangle".

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

You could wrap the textbox and button in an ASP:Panel, and set the DefaultButton property of the Panel to the Id of your Submit button.

<asp:Panel ID="Panel1" runat="server" DefaultButton="SubmitButton">
    <asp:TextBox ID="TextBox1" runat="server" />
    <asp:Button ID="SubmitButton" runat="server" Text="Submit" OnClick="SubmitButton_Click" />
</asp:Panel>

Now anytime the focus is within the Panel, the 'SubmitButton_Click' event will fire when enter is pressed.

Normally you cant update a page from a servlet. Client (browser) has to request an update. Eiter client loads a whole new page or it requests an update to a part of an existing page. This technique is called Ajax.

There is a built in method which is the most performant:

my_dataframe.columns.values.tolist()

.columns returns an Index, .columns.values returns an array and this has a helper function .tolist to return a list.

If performance is not as important to you, Index objects define a .tolist() method that you can call directly:

my_dataframe.columns.tolist()

The difference in performance is obvious:

%timeit df.columns.tolist()
16.7 µs ± 317 ns per loop (mean ± std. dev. of 7 runs, 100000 loops each)

%timeit df.columns.values.tolist()
1.24 µs ± 12.3 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

For those who hate typing, you can just call list on df, as so:

list(df)

it must be changed whenever anything changes that affects the serialization (additional fields, removed fields, change of field order, ...)

That's not correct, and you will be unable to cite an authoriitative source for that claim. It should be changed whenever you make a change that is incompatible under the rules given in the Versioning of Serializable Objects section of the Object Serialization Specification, which specifically does not include additional fields or change of field order, and when you haven't provided readObject(), writeObject(), and/or readResolve() or /writeReplace() methods and/or a serializableFields declaration that could cope with the change.

There are many crazy answers here and especially about CORS -

You could do an http HEAD request (like GET but without payload). See https://ochronus.com/http-head-request-good-uses/

It does NOT need a preflight check, the confusion is because of an old version of the specification, see Why does a cross-origin HEAD request need a preflight check?

So you could use the answer above which is using the jQuery library (didn't say it) but with

type: 'HEAD'

--->

<script>
    function ping(){
       $.ajax({
          url: 'ping.html',
          type: 'HEAD',
          success: function(result){
             alert('reply');
          },     
          error: function(result){
              alert('timeout/error');
          }
       });
    }
</script>

Off course you can also use vanilla js or dojo or whatever ...

I swear to God.. the solution to this utterly basic problem eluded me for YEARS. It's SO simple.. but there is so much vague / bad information out there; hopefully I can save someone from some of the bottomless rabbit holes that I ended up in...

So then, lets's get a "string" from "the user" via "the console", via stdin, shall we?

[NSString.alloc initWithData:
[NSFileHandle.fileHandleWithStandardInput availableData]
                          encoding:NSUTF8StringEncoding];

if you want it WITHOUT the trailing newline, just add...

[ ... stringByTrimmingCharactersInSet:
                       NSCharacterSet.newlineCharacterSet];

Ta Da! ? ??e?

As slashnick & bobince mention, hasChildNodes() will return true for whitespace (text nodes). However, I didn't want this behaviour, and this worked for me :)

element.getElementsByTagName('*').length > 0

Edit: for the same functionality, this is a better solution:

 element.children.length > 0

children[] is a subset of childNodes[], containing elements only.

Compatibility

You're very close:

while IFS=$'\t' read -r -a myArray
do
 echo "${myArray[0]}"
 echo "${myArray[1]}"
 echo "${myArray[2]}"
done < myfile

(The -r tells read that \ isn't special in the input data; the -a myArray tells it to split the input-line into words and store the results in myArray; and the IFS=$'\t' tells it to use only tabs to split words, instead of the regular Bash default of also allowing spaces to split words as well. Note that this approach will treat one or more tabs as the delimiter, so if any field is blank, later fields will be "shifted" into earlier positions in the array. Is that O.K.?)

1. 1. A HashSet holds a set of objects, but in a way that it allows you to easily and quickly determine whether an object is already in the set or not. It does so by internally managing an array and storing the object using an index which is calculated from the hashcode of the object. Take a look here

   2. HashSet is an unordered collection containing unique elements. It has the standard collection operations Add, Remove, Contains, but since it uses a hash-based implementation, these operations are O(1). (As opposed to List for example, which is O(n) for Contains and Remove.) HashSet also provides standard set operations such as union, intersection, and symmetric difference. Take a look here

2. There are different implementations of Sets. Some make insertion and lookup operations super fast by hashing elements. However, that means that the order in which the elements were added is lost. Other implementations preserve the added order at the cost of slower running times.

The HashSet class in C# goes for the first approach, thus not preserving the order of elements. It is much faster than a regular List. Some basic benchmarks showed that HashSet is decently faster when dealing with primary types (int, double, bool, etc.). It is a lot faster when working with class objects. So that point is that HashSet is fast.

The only catch of HashSet is that there is no access by indices. To access elements you can either use an enumerator or use the built-in function to convert the HashSet into a List and iterate through that. Take a look here

Write a Vim function in .vimrc using the searchpair built-in function:

searchpair({start}, {middle}, {end} [, {flags} [, {skip}
            [, {stopline} [, {timeout}]]]])
    Search for the match of a nested start-end pair.  This can be
    used to find the "endif" that matches an "if", while other
    if/endif pairs in between are ignored.
    [...]

There is actually a reason behind why all these are messed up. A little more digging deeper is done in this thread and might be helpful to understand the reason why "\\" behaves like this.

Your code should work, but you can also try:

    if not item in mylist :

struct rect
{
    int x;
    int y;
    int width;
    int height;
};

bool valueInRange(int value, int min, int max)
{ return (value >= min) && (value <= max); }

bool rectOverlap(rect A, rect B)
{
    bool xOverlap = valueInRange(A.x, B.x, B.x + B.width) ||
                    valueInRange(B.x, A.x, A.x + A.width);

    bool yOverlap = valueInRange(A.y, B.y, B.y + B.height) ||
                    valueInRange(B.y, A.y, A.y + A.height);

    return xOverlap && yOverlap;
}

I did the following steps to resolve the issue. On the branch which was giving me the error:

1. git pull origin [branch-name]<current branch>
2. After pulling, got some merge issues, solved them, pushed the changes to the same branch.
3. Created the Pull request with the pushed branch... tada, My changes were reflecting, all of them.

x <- rnorm(10) * 100000
y <- seq(0, 1, length = 10)
p <- qplot(x, y)

p + scale_x_continuous(labels = comma)

In case anyone else is wondering, you can use is_ to generate foo IS NULL:

>>> from sqlalchemy.sql import column
>>> print column('foo').is_(None)
foo IS NULL
>>> print column('foo').isnot(None)
foo IS NOT NULL

Sometimes (too often!) I have to untangle someone else's C++ code. And we all know that someone else's C++ code is a complete mess almost by definition :) So the first thing I do to decipher local data flow is put const in every variable definition until compiler starts barking. This means const-qualifying value arguments as well, because they are just fancy local variables initialized by caller.

Ah, I wish variables were const by default and mutable was required for non-const variables :)

If any of these characters, '>', '<', '|' or '*', are used, a single or double quotes must be used

Two other alternatives:

3. a combination of NULLIF and NVL2. You can only use this if emp_id is NOT NULL, which it is in your case:

   select nvl2(nullif(emp_id,1),'False','True') from employee;
   

4. simple CASE expression (Mt. Schneiders used a so-called searched CASE expression)

   select case emp_id when 1 then 'True' else 'False' end from employee;
   

You can also put the item with the default value selected out of the ng-repeat like follow :

<div ng-app="app" ng-controller="myCtrl">
    <select class="form-control" ng-change="unitChanged()" ng-model="data.unit">
        <option value="yourDefaultValue">Default one</option>
        <option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>
    </select>
</div>

and don't forget the value atribute if you leave it blank you will have the same issue.

If you want something more similar to your example try _itot_s. On Microsoft compilers _itot_s points to _itoa_s or _itow_s depending on your Unicode setting:

CString str;
_itot_s( 15, str.GetBufferSetLength( 40 ), 40, 10 );
str.ReleaseBuffer();

it should be slightly faster since it doesn't need to parse an input format.

Some test results

I've gotten a lot of good answers to this question--thanks folks--so I decided to run some tests and figure out which method is actually fastest. The five methods I tested are these:

• the "ContainsKey" method that I presented in the question
• the "TestForNull" method suggested by Aleksandar Dimitrov
• the "AtomicLong" method suggested by Hank Gay
• the "Trove" method suggested by jrudolph
• the "MutableInt" method suggested by phax.myopenid.com

Method

Here's what I did...

1. created five classes that were identical except for the differences shown below. Each class had to perform an operation typical of the scenario I presented: opening a 10MB file and reading it in, then performing a frequency count of all the word tokens in the file. Since this took an average of only 3 seconds, I had it perform the frequency count (not the I/O) 10 times.
2. timed the loop of 10 iterations but not the I/O operation and recorded the total time taken (in clock seconds) essentially using Ian Darwin's method in the Java Cookbook.
3. performed all five tests in series, and then did this another three times.
4. averaged the four results for each method.

Results

I'll present the results first and the code below for those who are interested.

The ContainsKey method was, as expected, the slowest, so I'll give the speed of each method in comparison to the speed of that method.

• ContainsKey: 30.654 seconds (baseline)
• AtomicLong: 29.780 seconds (1.03 times as fast)
• TestForNull: 28.804 seconds (1.06 times as fast)
• Trove: 26.313 seconds (1.16 times as fast)
• MutableInt: 25.747 seconds (1.19 times as fast)

Conclusions

It would appear that only the MutableInt method and the Trove method are significantly faster, in that only they give a performance boost of more than 10%. However, if threading is an issue, AtomicLong might be more attractive than the others (I'm not really sure). I also ran TestForNull with final variables, but the difference was negligible.

Note that I haven't profiled memory usage in the different scenarios. I'd be happy to hear from anybody who has good insights into how the MutableInt and Trove methods would be likely to affect memory usage.

Personally, I find the MutableInt method the most attractive, since it doesn't require loading any third-party classes. So unless I discover problems with it, that's the way I'm most likely to go.

The code

Here is the crucial code from each method.

ContainsKey

import java.util.HashMap;
import java.util.Map;
...
Map<String, Integer> freq = new HashMap<String, Integer>();
...
int count = freq.containsKey(word) ? freq.get(word) : 0;
freq.put(word, count + 1);

TestForNull

import java.util.HashMap;
import java.util.Map;
...
Map<String, Integer> freq = new HashMap<String, Integer>();
...
Integer count = freq.get(word);
if (count == null) {
    freq.put(word, 1);
}
else {
    freq.put(word, count + 1);
}

AtomicLong

import java.util.concurrent.ConcurrentHashMap;
import java.util.concurrent.ConcurrentMap;
import java.util.concurrent.atomic.AtomicLong;
...
final ConcurrentMap<String, AtomicLong> map = 
    new ConcurrentHashMap<String, AtomicLong>();
...
map.putIfAbsent(word, new AtomicLong(0));
map.get(word).incrementAndGet();

Trove

import gnu.trove.TObjectIntHashMap;
...
TObjectIntHashMap<String> freq = new TObjectIntHashMap<String>();
...
freq.adjustOrPutValue(word, 1, 1);

MutableInt

import java.util.HashMap;
import java.util.Map;
...
class MutableInt {
  int value = 1; // note that we start at 1 since we're counting
  public void increment () { ++value;      }
  public int  get ()       { return value; }
}
...
Map<String, MutableInt> freq = new HashMap<String, MutableInt>();
...
MutableInt count = freq.get(word);
if (count == null) {
    freq.put(word, new MutableInt());
}
else {
    count.increment();
}

If you select the log entry to which you want to revert to then you can click on "Reset to this commit". Only use this option if you didn't push the reverse commit changes. If you're worried about losing the changes then you can use the soft mode which will leave a set of uncommitted changes (what you just changed). Using the mixed resets the working copy but keeps those changes, and a hard will just get rid of the changes entirely. Here's some screenshots:

I don't think this is possible with AD. The distinguishedName attribute is the only thing I know of that contains the OU piece on which you're trying to search, so you'd need a wildcard to get results for objects under those OUs. Unfortunately, the wildcard character isn't supported on DNs.

If at all possible, I'd really look at doing this in 2 queries using OU=Staff... and OU=Vendors... as the base DNs.

Robust C89 strtol-based solution

With:

• no undefined behavior (as could be had with the atoi family)
• a stricter definition of integer than strtol (e.g. no leading whitespace nor trailing trash chars)
• classification of the error case (e.g. to give useful error messages to users)
• a "testsuite"

#include <assert.h>
#include <ctype.h>
#include <errno.h>
#include <limits.h>
#include <stdio.h>
#include <stdlib.h>

typedef enum {
    STR2INT_SUCCESS,
    STR2INT_OVERFLOW,
    STR2INT_UNDERFLOW,
    STR2INT_INCONVERTIBLE
} str2int_errno;

/* Convert string s to int out.
 *
 * @param[out] out The converted int. Cannot be NULL.
 *
 * @param[in] s Input string to be converted.
 *
 *     The format is the same as strtol,
 *     except that the following are inconvertible:
 *
 *     - empty string
 *     - leading whitespace
 *     - any trailing characters that are not part of the number
 *

A succinct way to convert a single column of boolean values to a column of integers 1 or 0:

df["somecolumn"] = df["somecolumn"].astype(int)

If none of the other answers are satisfactory, you could always just create an empty row and style it with CSS appropriately to be transparent.

With no doctype tag, Chrome reports the same value for both calls.

Adding a strict doctype like <!DOCTYPE html> causes the values to work as advertised.

The doctype tag must be the very first thing in your document. E.g., you can't have any text before it, even if it doesn't render anything.

Given

var animals = ["cats", "dogs", "chimps", "moose"]

Remove first element

animals.removeFirst() // "cats"
print(animals)        // ["dogs", "chimps", "moose"]

Remove last element

animals.removeLast() // "moose"
print(animals)       // ["cats", "dogs", "chimps"]

Remove element at index

animals.remove(at: 2) // "chimps"
print(animals)           // ["cats", "dogs", "moose"]

Remove element of unknown index

For only one element

if let index = animals.firstIndex(of: "chimps") {
    animals.remove(at: index)
}
print(animals) // ["cats", "dogs", "moose"]

For multiple elements

var animals = ["cats", "dogs", "chimps", "moose", "chimps"]

animals = animals.filter(){$0 != "chimps"}
print(animals) // ["cats", "dogs", "moose"]

Notes

• The above methods modify the array in place (except for filter) and return the element that was removed.
• Swift Guide to Map Filter Reduce
• If you don't want to modify the original array, you can use dropFirst or dropLast to create a new array.

Updated to Swift 5.2

Here is an answer to your question that goes into detail: http://www.velocityreviews.com/forums/t372598-maximum-size-of-byte-array.html

You may want to mention which version of .NET you are using and your memory size.

You will be stuck to a 2G, for your application, limit though, so it depends on what is in your array.

I figured it out. I was using a bad example I found in the past of how to map query string to the method parameters.

In case anyone else needs it, in order to have optional parameters in a query string such as:

• ~/api/products/filter?apc=AA&xpc=BB
• ~/api/products/filter?sku=7199123

you would use:

[Route("products/filter/{apc?}/{xpc?}/{sku?}")]
public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

It seems odd to have to define default values for the method parameters when these types already have a default.

I don't think there is a way to do variable length string comparisons completely in preprocessor directives. You could perhaps do the following though:

#define USER_JACK 1
#define USER_QUEEN 2

#define USER USER_JACK 

#if USER == USER_JACK
#define USER_VS USER_QUEEN
#elif USER == USER_QUEEN
#define USER_VS USER_JACK
#endif

Or you could refactor the code a little and use C code instead.

Try smallR for writing quick R scripts in the command line:

http://code.google.com/p/simple-r/

(r command in the directory)

Plotting from the command line using smallR would look like this:

r -p file.txt

Only need to set it to

DateTime.Now.Date

Console.WriteLine(DateTime.Now.Date.ToString("yyyy-MM-dd HH:mm:ss"));
Console.Read();

It shows

"2017-04-08 00:00:00"

on my machine.

The correct way to do this is:

String[] stockArr = stock_list.toArray(new String[stock_list.size()]);

I'd like to add to the other great answers here and explain how you could have used the Javadocs to answer your question.

The Javadoc for toArray() (no arguments) is here. As you can see, this method returns an Object[] and not String[] which is an array of the runtime type of your list:

public Object[] toArray()

Returns an array containing all of the elements in this collection. If the collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order. The returned array will be "safe" in that no references to it are maintained by the collection. (In other words, this method must allocate a new array even if the collection is backed by an Array). The caller is thus free to modify the returned array.

Right below that method, though, is the Javadoc for toArray(T[] a). As you can see, this method returns a T[] where T is the type of the array you pass in. At first this seems like what you're looking for, but it's unclear exactly why you're passing in an array (are you adding to it, using it for just the type, etc). The documentation makes it clear that the purpose of the passed array is essentially to define the type of array to return (which is exactly your use case):

public <T> T[] toArray(T[] a)

Returns an array containing all of the elements in this collection; the runtime type of the returned array is that of the specified array. If the collection fits in the specified array, it is returned therein. Otherwise, a new array is allocated with the runtime type of the specified array and the size of this collection. If the collection fits in the specified array with room to spare (i.e., the array has more elements than the collection), the element in the array immediately following the end of the collection is set to null. This is useful in determining the length of the collection only if the caller knows that the collection does not contain any null elements.)

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

This implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). Then, it iterates over the collection, storing each object reference in the next consecutive element of the array, starting with element 0. If the array is larger than the collection, a null is stored in the first location after the end of the collection.

Of course, an understanding of generics (as described in the other answers) is required to really understand the difference between these two methods. Nevertheless, if you first go to the Javadocs, you will usually find your answer and then see for yourself what else you need to learn (if you really do).

Also note that reading the Javadocs here helps you to understand what the structure of the array you pass in should be. Though it may not really practically matter, you should not pass in an empty array like this:

String [] stockArr = stockList.toArray(new String[0]);  

Because, from the doc, this implementation checks if the array is large enough to contain the collection; if not, it allocates a new array of the correct size and type (using reflection). There's no need for the extra overhead in creating a new array when you could easily pass in the size.

As is usually the case, the Javadocs provide you with a wealth of information and direction.

Hey wait a minute, what's reflection?

These have the same end result, but I would simply add that using the literal syntax can help one become accustomed to the syntax of JSON (a string-ified subset of JavaScript literal object syntax), so it might be a good practice to get into.

One other thing: you might have subtle errors if you forget to use the new operator. So, using literals will help you avoid that problem.

Ultimately, it will depend on the situation as well as preference.

you can also used findOrFail() method here it's good to used

if the exception is not caught, a 404 HTTP response is automatically sent back to the user. It is not necessary to write explicit checks to return 404 responses when using these method not give a 500 error..

ModelName::findOrFail($id, ['firstName', 'lastName']);

If you simply place text as a child(ren) of a column, this is the easiest way to have text automatically wrap. Assuming you don't have anything more complicated going on. In those cases, I would think you would create your container sized as you see fit and put another column inside and then your text. This seems to work nicely. Containers want to shrink to the size of its contents, and this seems to naturally conflict with wrapping, which requires more effort.

Column(
  mainAxisSize: MainAxisSize.min,
  children: <Widget>[
    Text('This long text will wrap very nicely if there isn't room beyond the column\'s total width and if you have enough vertical space available to wrap into.',
      style: TextStyle(fontSize: 16, color: primaryColor),
      textAlign: TextAlign.center,),
  ],
),

You can also manually tag the column with a contrasts attribute, which seems to be respected by the regression functions:

contrasts(df$factorcol) <- contr.treatment(levels(df$factorcol),
   base=which(levels(df$factorcol) == 'RefLevel'))

This error comes because of a merge conflict in files. I faced it after I had updated my Maven Project's pom.xml but didn't commit it. Using

git status
error: Your local changes to the following files would be overwritten by merge:
<my project>/pom.xml
Please, commit your changes or stash them before you can merge.
Aborting

as the above post suggested helped finding any conflicting changes and you can decide to discard or commit.

Here is my answer for python 3.

some_string = "2 3 8 61 "

list(map(int, some_string.strip().split()))

You can directly go to Web IDE and upload your folder there.

Steps:

1. Go to Web IDE(Mostly located below the clone option).
2. Create new directory at your path
3. Upload your files and folders

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

you can use these styles:

style="border-left: 1px solid #cdd0d4;"  
style="border-bottom: 1px solid #cdd0d4;"
style="border-top: 1px solid #cdd0d4;"
style="border-right: 1px solid #cdd0d4;"

with this you want u must use

<td style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;">  

or

<img style="border-left: 1px solid #cdd0d4;border-bottom: 1px solid #cdd0d4;"> 

Why not simply using background-clip?

I tried pydiction (didn't work for me) and the normal omnicompletion (too limited). I looked into Jedi as suggested but found it too complex to set up. I found python-mode, which in the end satisfied my needs. Thanks @klen.

Checking for undefined-ness is not an accurate way of testing whether a key exists. What if the key exists but the value is actually undefined?

var obj = { key: undefined };
obj["key"] !== undefined // false, but the key exists!

You should instead use the in operator:

"key" in obj // true, regardless of the actual value

If you want to check if a key doesn't exist, remember to use parenthesis:

!("key" in obj) // true if "key" doesn't exist in object
!"key" in obj   // Do not do this! It is equivalent to "false in obj"

Or, if you want to particularly test for properties of the object instance (and not inherited properties), use hasOwnProperty:

obj.hasOwnProperty("key") // true

For performance comparison between the methods that are in, hasOwnProperty and key is undefined, see this benchmark

I know this question is old, but there is a way to solve this until C++20 finally brings this feature from C to C++. What you can do to solve this is use preprocessor macros with static_asserts to check your initialization is valid. (I know macros are generally bad, but here I don't see another way.) See example code below:

#define INVALID_STRUCT_ERROR "Instantiation of struct failed: Type, order or number of attributes is wrong."

#define CREATE_STRUCT_1(type, identifier, m_1, p_1) \
{ p_1 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\

#define CREATE_STRUCT_2(type, identifier, m_1, p_1, m_2, p_2) \
{ p_1, p_2 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\

#define CREATE_STRUCT_3(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3) \
{ p_1, p_2, p_3 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\

#define CREATE_STRUCT_4(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3, m_4, p_4) \
{ p_1, p_2, p_3, p_4 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_4) >= (offsetof(type, m_3) + sizeof(identifier.m_3)), INVALID_STRUCT_ERROR);\

// Create more macros for structs with more attributes...

Then when you have a struct with const attributes, you can do this:

struct MyStruct
{
    const int attr1;
    const float attr2;
    const double attr3;
};

const MyStruct test = CREATE_STRUCT_3(MyStruct, test, attr1, 1, attr2, 2.f, attr3, 3.);

It's a bit inconvenient, because you need macros for every possible number of attributes and you need to repeat the type and name of your instance in the macro call. Also you cannot use the macro in a return statement, because the asserts come after the initialization.

But it does solve your problem: When you change the struct, the call will fail at compile-time.

If you use C++17, you can even make these macros more strict by forcing the same types, e.g.:

#define CREATE_STRUCT_3(type, identifier, m_1, p_1, m_2, p_2, m_3, p_3) \
{ p_1, p_2, p_3 };\
static_assert(offsetof(type, m_1) == 0, INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_2) >= sizeof(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(offsetof(type, m_3) >= (offsetof(type, m_2) + sizeof(identifier.m_2)), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_1) == typeid(identifier.m_1), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_2) == typeid(identifier.m_2), INVALID_STRUCT_ERROR);\
static_assert(typeid(p_3) == typeid(identifier.m_3), INVALID_STRUCT_ERROR);\

One of the simple solution could be just keep swapping the characters recursively using two pointers.

public static void main(String[] args)
{
    String str="abcdefgh";
    perm(str);
}
public static void perm(String str)
{  char[] char_arr=str.toCharArray();
    helper(char_arr,0);
}
public static void helper(char[] char_arr, int i)
{
    if(i==char_arr.length-1)
    {
        // print the shuffled string 
            String str="";
            for(int j=0; j<char_arr.length; j++)
            {
                str=str+char_arr[j];
            }
            System.out.println(str);
    }
    else
    {
    for(int j=i; j<char_arr.length; j++)
    {
        char tmp = char_arr[i];
        char_arr[i] = char_arr[j];
        char_arr[j] = tmp;
        helper(char_arr,i+1);
        char tmp1 = char_arr[i];
        char_arr[i] = char_arr[j];
        char_arr[j] = tmp1;
    }
}
}

I had the same problem. Get the warning. Went to Data connections and deleted connection. Save, close reopen. Still get the warning. I use a xp/vista menu plugin for classic menus. I found under data, get external data, properties, uncheck the save query definition. Save close and reopen. That seemed to get rid of the warning. Just removing the connection does not work. You have to get rid of the query.

onMeasure() is your opportunity to tell Android how big you want your custom view to be dependent the layout constraints provided by the parent; it is also your custom view's opportunity to learn what those layout constraints are (in case you want to behave differently in a match_parent situation than a wrap_content situation). These constraints are packaged up into the MeasureSpec values that are passed into the method. Here is a rough correlation of the mode values:

• EXACTLY means the layout_width or layout_height value was set to a specific value. You should probably make your view this size. This can also get triggered when match_parent is used, to set the size exactly to the parent view (this is layout dependent in the framework).
• AT_MOST typically means the layout_width or layout_height value was set to match_parent or wrap_content where a maximum size is needed (this is layout dependent in the framework), and the size of the parent dimension is the value. You should not be any larger than this size.
• UNSPECIFIED typically means the layout_width or layout_height value was set to wrap_content with no restrictions. You can be whatever size you would like. Some layouts also use this callback to figure out your desired size before determine what specs to actually pass you again in a second measure request.

The contract that exists with onMeasure() is that setMeasuredDimension() MUST be called at the end with the size you would like the view to be. This method is called by all the framework implementations, including the default implementation found in View, which is why it is safe to call super instead if that fits your use case.

Granted, because the framework does apply a default implementation, it may not be necessary for you to override this method, but you may see clipping in cases where the view space is smaller than your content if you do not, and if you lay out your custom view with wrap_content in both directions, your view may not show up at all because the framework doesn't know how large it is!

Generally, if you are overriding View and not another existing widget, it is probably a good idea to provide an implementation, even if it is as simple as something like this:

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

    int desiredWidth = 100;
    int desiredHeight = 100;

    int widthMode = MeasureSpec.getMode(widthMeasureSpec);
    int widthSize = MeasureSpec.getSize(widthMeasureSpec);
    int heightMode = MeasureSpec.getMode(heightMeasureSpec);
    int heightSize = MeasureSpec.getSize(heightMeasureSpec);

    int width;
    int height;

    //Measure Width
    if (widthMode == MeasureSpec.EXACTLY) {
        //Must be this size
        width = widthSize;
    } else if (widthMode == MeasureSpec.AT_MOST) {
        //Can't be bigger than...
        width = Math.min(desiredWidth, widthSize);
    } else {
        //Be whatever you want
        width = desiredWidth;
    }

    //Measure Height
    if (heightMode == MeasureSpec.EXACTLY) {
        //Must be this size
        height = heightSize;
    } else if (heightMode == MeasureSpec.AT_MOST) {
        //Can't be bigger than...
        height = Math.min(desiredHeight, heightSize);
    } else {
        //Be whatever you want
        height = desiredHeight;
    }

    //MUST CALL THIS
    setMeasuredDimension(width, height);
}

Hope that Helps.

Probably svn import would be the best option around. Check out Getting Data into Your Repository (in Version Control with Subversion, For Subversion).

The svn import command is a quick way to copy an unversioned tree of files into a repository, creating intermediate directories as necessary. svn import doesn't require a working copy, and your files are immediately committed to the repository. You typically use this when you have an existing tree of files that you want to begin tracking in your Subversion repository. For example:

$ svn import /path/to/mytree \
             http://svn.example.com/svn/repo/some/project \
             -m "Initial import"
Adding         mytree/foo.c
Adding         mytree/bar.c
Adding         mytree/subdir
Adding         mytree/subdir/quux.h

Committed revision 1.
$

The previous example copied the contents of the local directory mytree into the directory some/project in the repository. Note that you didn't have to create that new directory first—svn import does that for you. Immediately after the commit, you can see your data in the repository:

$ svn list http://svn.example.com/svn/repo/some/project
bar.c
foo.c
subdir/
$

Note that after the import is finished, the original local directory is not converted into a working copy. To begin working on that data in a versioned fashion, you still need to create a fresh working copy of that tree.

Note: if you are on the same machine as the Subversion repository you can use the file:// specifier with a path rather than the https:// with a URL specifier.

In your invoke web request just use the parameter -UseBasicParsing

e.g. in your script (line 2) you should use:

$rss = Invoke-WebRequest -Uri $url -UseBasicParsing

According to the documentation, this parameter is necessary on systems where IE isn't installed or configured:

Uses the response object for HTML content without Document Object Model (DOM) parsing. This parameter is required when Internet Explorer is not installed on the computers, such as on a Server Core installation of a Windows Server operating system.

List :

1. List is ordered grouping elements
2. List provides positional access in the elements of the collections.
3. We can store duplicate elements in the list.
4. List implements ArrayList, LinkedList, Vector and Stack.
5. List can store multiple null elements.

Set :

1. Unorderd grouping elements.
2. Set doesn’t provides positional access in the elements of the collections.
3. We can’t store duplicate elements in the set.
4. Set implement HashSet and LinkedHashSet interfaces.
5. Set can store only one null elements.

HTML

<p>Gender</p>
<input type="radio" id="gender0" name="gender" value="Male">Male<br>
<input type="radio" id="gender1" name="gender" value="Female">Female<br>

JS

var gender = document.querySelector('input[name = "gender"]:checked').value;
document.writeln("You entered " + gender + " for your gender<br>");

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

You can use HTTP Toolkit to do exactly this.

It's especially useful if you need to do this quickly, with no code changes: you can open a terminal from HTTP Toolkit, run any Python code from there as normal, and you'll be able to see the full content of every HTTP/HTTPS request immediately.

There's a free version that can do everything you need, and it's 100% open source.

I'm the creator of HTTP Toolkit; I actually built it myself to solve the exact same problem for me a while back! I too was trying to debug a payment integration, but their SDK didn't work, I couldn't tell why, and I needed to know what was actually going on to properly fix it. It's very frustrating, but being able to see the raw traffic really helps.

If it suits anyone, here are some brief guidelines for adding environment variables permanently.

vi ~/.bash_profile

Add the variables to the file:

export DISPLAY=:0
export JAVA_HOME=~/opt/openjdk11

Immediately apply all changes:

You may want to build a virtualenv of python3, then install packages of python3 after activating the virtualenv. So your system won't be messed up :)

This could be something like:

virtualenv -p /usr/bin/python3 py3env
source py3env/bin/activate
pip install package-name

Double quotes around the filename in the header is the standard per MDN web docs. Omitting the quotes creates multiple opportunities for problems arising from characters in the filename.

I just used the @misir-jafarov and is working now with :

• IE 8,9,10,11 and EDGE detection
• used in Bootrap 4
• take the height of its parent div
• cliped vertically at 20% of top and horizontally 50% (better for portraits)

here is my code :

if (document.documentMode || /Edge/.test(navigator.userAgent)) {
    jQuery('.art-img img').each(function(){
        var t = jQuery(this),
            s = 'url(' + t.attr('src') + ')',
            p = t.parent(),
            d = jQuery('<div></div>');

        p.append(d);
        d.css({
            'height'                : t.parent().css('height'),
            'background-size'       : 'cover',
            'background-repeat'     : 'no-repeat',
            'background-position'   : '50% 20%',
            'background-image'      : s
        });
        t.hide();
    });
}

Hope it helps.

Here's my solution using TimeUnit.

UPDATE: I should point out that this is written in groovy, but Java is almost identical.

def remainingStr = ""

/* Days */
int days = MILLISECONDS.toDays(remainingTime) as int
remainingStr += (days == 1) ? '1 Day : ' : "${days} Days : "
remainingTime -= DAYS.toMillis(days)

/* Hours */
int hours = MILLISECONDS.toHours(remainingTime) as int
remainingStr += (hours == 1) ? '1 Hour : ' : "${hours} Hours : "
remainingTime -= HOURS.toMillis(hours)

/* Minutes */
int minutes = MILLISECONDS.toMinutes(remainingTime) as int
remainingStr += (minutes == 1) ? '1 Minute : ' : "${minutes} Minutes : "
remainingTime -= MINUTES.toMillis(minutes)

/* Seconds */
int seconds = MILLISECONDS.toSeconds(remainingTime) as int
remainingStr += (seconds == 1) ? '1 Second' : "${seconds} Seconds"

They are several ways to run python script:

• run by double click on file.py (it opens the python command line)
• run your file.py from the cmd prompt (cmd) (drag/drop your file on it for instance)
• run your file.py in your IDE (eg. pyscripter or Pycharm)

Each of these ways can run a different version of python (¤)

Check which python version is run by cmd: Type in cmd:

python --version 

Check which python version is run when clicking on .py:

option 1:

create a test.py containing this:

import sys print (sys.version)
input("exit")

Option 2:

type in cmd:

assoc .py
ftype Python.File

Check the path and if the module (ex: win32clipboard) is recognized in the cmd:

create a test.py containing this:

python
import sys
sys.executable
sys.path
import win32clipboard
win32clipboard.__file__

Check the path and if module is recognized in the .py

create a test.py containing this:

import sys
print(sys.executable)
print(sys.path)
import win32clipboard
print(win32clipboard.__file__)

If the version in cmd is ok but not in .py it's because the default program associated with .py isn't the right one. Change python version for .py

To change the python version associated with cmd:

Control Panel\All Control Panel Items\System\Advanced system setting\Environnement variable In SYSTEM variable set the path variable to you python version (the path are separated by ;: cmd use the FIRST path eg: C:\path\to\Python27;C:\path\to\Python35 ? cmd will use python27)

To change the python version associated with .py extension:

Run cmd as admin:

Write: ftype Python.File="C:\Python35\python.exe" "%1" %* It will set the last python version (eg. python3.6). If your last version is 3.6 but you want 3.5 just add some xxx in your folder (xxxpython36) so it will take the last recognized version which is python3.5 (after the cmd remove the xxx).

Other:

"No modul error" could also come from a syntax error btw python et 3 (eg. missing parenthesis for print function...)

¤ Thus each of them has it's own pip version

I think we also need to give the fpm container the volume, dont we? So =>

fpm:
    image: php:fpm
    volumes:
        - ./:/var/www/test/

If i dont do this, i run into this exception when firing a request, as fpm cannot find requested file:

[error] 6#6: *4 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 172.17.42.1, server: localhost, request: "GET / HTTP/1.1", upstream: "fastcgi://172.17.0.81:9000", host: "localhost"

You could use a HTML DTD, and the generic XML parsing libraries.

If you want to use std::string reliably, you must #include <string>.

Something like Nigel Cohen's would work if you were adding data to a copy of the collected set of form data:

form = FormType(request.POST)
if request.method == "POST":
    formcopy = form(request.POST.copy())
    formcopy.data['Email'] = GetEmailString()

I'm the creator of Restangular.

You can take a look at this CRUD example to see how you can PUT/POST/GET elements without all that URL configuration and $resource configuration that you need to do. Besides it, you can then use nested resources without any configuration :).

Check out this plunkr example:

You could also see the README and check the documentation here https://github.com/mgonto/restangular

If you need some feature that's not there, just create an issue. I usually add features asked within a week, as I also use this library for all my AngularJS projects :)

Hope it helps!

Open Chrome Developer Tools, go to Network tab, make your request (you may need to check "Preserve Log" if the page refreshes). Find the request on the left, right-click, "Copy as cURL".

Use jquery.inputmask 3.x. See demos here

Include files:

<script src="/assets/jquery.inputmask.js" type="text/javascript"></script>
<script src="/assets/jquery.inputmask.extensions.js" type="text/javascript"></script>
<script src="/assets/jquery.inputmask.numeric.extensions.js" type="text/javascript"></script>

And code as

$(selector).inputmask('decimal',
  { 'alias': 'numeric',
    'groupSeparator': '.',
    'autoGroup': true,
    'digits': 2,
    'radixPoint': ",",
    'digitsOptional': false,
    'allowMinus': false,
    'prefix': '$ ',
    'placeholder': '0'
  }
);

Highlights:

• easy to use
• optional parts anywere in the mask
• possibility to define aliases which hide complexity
• date / datetime masks
• numeric masks
• lots of callbacks
• non-greedy masks
• many features can be enabled/disabled/configured by options
• supports readonly/disabled/dir="rtl" attributes
• support data-inputmask attribute(s)
• multi-mask support
• regex-mask support
• dynamic-mask support
• preprocessing-mask support
• value formatting / validating without input element

#define NAME(x) printf("Hello " #x);
main(){
    NAME(Ian)
}
//will print: Hello Ian

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

This can be done using httpPostedFileBase class returns the HttpInputStreamObject as per specified here

You should convert the stream into byte array and then you can read file content

Please refer following link

http://msdn.microsoft.com/en-us/library/system.web.httprequest.inputstream.aspx]

Hope this helps

UPDATE :

The stream that you get from your HTTP call is read-only sequential (non-seekable) and the FileStream is read/write seekable. You will need first to read the entire stream from the HTTP call into a byte array, then create the FileStream from that array.

Taken from here

// Read bytes from http input stream
BinaryReader b = new BinaryReader(file.InputStream);
byte[] binData = b.ReadBytes(file.ContentLength);

string result = System.Text.Encoding.UTF8.GetString(binData);

argc is the number of command line arguments and argv is array of strings representing command line arguments.

This gives you the option to react to the arguments passed to the program. If you are expecting none, you might as well use int main.

Or use group_by & summarise_at from the dplyr package:

library(dplyr)

d %>%
  group_by(Name) %>%
  summarise_at(vars(-Month), funs(mean(., na.rm=TRUE)))

# A tibble: 3 x 3
  Name  Rate1 Rate2
  <fct> <dbl> <dbl>
1 Aira   16.3  47.0
2 Ben    31.3  50.3
3 Cat    44.7  54.0

See ?summarise_at for the many ways to specify the variables to act on. Here, vars(-Month) says all variables except Month.

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)

You only need to import it:

import tkinter as tk

then you will be use the phrase tk, which is shorter and easier.

Also, I prefer using messagebox too:

from tkinter import messagebox as msgbx

Here's some ways you will be able to use it.

# make a new window
window = tk.Tk()

# show popup
msgbx.showinfo("title", "This is a text")

Instead of using onload, use Angular's ng-init.

<article id="showSelector" ng-controller="CinemaCtrl" ng-init="myFunction()">

Note: This requires that myFunction is a property of the CinemaCtrl scope.

<div style="height: 100px;"> </div>

OR

<div id="foo"/> and set the style as #foo { height: 100px; }
<div class="bar"/> and set the style as .bar{ height: 100px;  }

Here the output will be false , false beacuse in first sopln statement you are trying to compare a string type varible of Myclass type to the other MyClass type and it will allow because of both are Object type and you have used "==" oprerator which will check the reference variable value holding the actual memory not the actual contnets inside the memory . In the second sopln also it is the same as you are again calling a.equals(object2) where a is a varible inside object1 . Do let me know your findings on this .

I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing } character. What's the length of result1 versus result2? I'll note that result2 as you've quoted it has 169 characters.

GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t, \n, \r, and space count as whitespace. In particular, note that trailing NUL (\0) characters do not count as whitespace and will cause this error.

If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);

If one is wanting to iterate through an array (Array or more generally any SequenceType) in reverse. You have a few additional options.

First you can reverse() the array and loop through it as normal. However I prefer to use enumerate() much of the time since it outputs a tuple containing the object and it's index.

The one thing to note here is that it is important to call these in the right order:

for (index, element) in array.enumerate().reverse()

yields indexes in descending order (which is what I generally expect). whereas:

for (index, element) in array.reverse().enumerate() (which is a closer match to NSArray's reverseEnumerator)

walks the array backward but outputs ascending indexes.

May not be the exact one-liner you were hoping for but you could have a look at http://github.com/nodejitsu/node-http-proxy as that may shed some light on how you can use your app with http.Client.

//Calculate number of hours between pass and now
$dayinpass = "2013-06-23 05:09:12";
$today = time();
$dayinpass= strtotime($dayinpass);
echo round(abs($today-$dayinpass)/60/60);

What's the pythonic way to use getters and setters?

The "Pythonic" way is not to use "getters" and "setters", but to use plain attributes, like the question demonstrates, and del for deleting (but the names are changed to protect the innocent... builtins):

value = 'something'

obj.attribute = value  
value = obj.attribute
del obj.attribute

If later, you want to modify the setting and getting, you can do so without having to alter user code, by using the property decorator:

class Obj:
    """property demo"""
    #
    @property            # first decorate the getter method
    def attribute(self): # This getter method name is *the* name
        return self._attribute
    #
    @attribute.setter    # the property decorates with `.setter` now
    def attribute(self, value):   # name, e.g. "attribute", is the same
        self._attribute = value   # the "value" name isn't special
    #
    @attribute.deleter     # decorate with `.deleter`
    def attribute(self):   # again, the method name is the same
        del self._attribute

(Each decorator usage copies and updates the prior property object, so note that you should use the same name for each set, get, and delete function/method.

After defining the above, the original setting, getting, and deleting code is the same:

obj = Obj()
obj.attribute = value  
the_value = obj.attribute
del obj.attribute

You should avoid this:

def set_property(property,value):  
def get_property(property):  

Firstly, the above doesn't work, because you don't provide an argument for the instance that the property would be set to (usually self), which would be:

class Obj:

    def set_property(self, property, value): # don't do this
        ...
    def get_property(self, property):        # don't do this either
        ...

Secondly, this duplicates the purpose of two special methods, __setattr__ and __getattr__.

Thirdly, we also have the setattr and getattr builtin functions.

setattr(object, 'property_name', value)
getattr(object, 'property_name', default_value)  # default is optional

The @property decorator is for creating getters and setters.

For example, we could modify the setting behavior to place restrictions the value being set:

class Protective(object):

    @property
    def protected_value(self):
        return self._protected_value

    @protected_value.setter
    def protected_value(self, value):
        if acceptable(value): # e.g. type or range check
            self._protected_value = value

In general, we want to avoid using property and just use direct attributes.

This is what is expected by users of Python. Following the rule of least-surprise, you should try to give your users what they expect unless you have a very compelling reason to the contrary.

Demonstration

For example, say we needed our object's protected attribute to be an integer between 0 and 100 inclusive, and prevent its deletion, with appropriate messages to inform the user of its proper usage:

class Protective(object):
    """protected property demo"""
    #
    def __init__(self, start_protected_value=0):
        self.protected_value = start_protected_value
    # 
    @property
    def protected_value(self):
        return self._protected_value
    #
    @protected_value.setter
    def protected_value(self, value):
        if value != int(value):
            raise TypeError("protected_value must be an integer")
        if 0 <= value <= 100:
            self._protected_value = int(value)
        else:
            raise ValueError("protected_value must be " +
                             "between 0 and 100 inclusive")
    #
    @protected_value.deleter
    def protected_value(self):
        raise AttributeError("do not delete, protected_value can be set to 0")

(Note that __init__ refers to self.protected_value but the property methods refer to self._protected_value. This is so that __init__ uses the property through the public API, ensuring it is "protected".)

And usage:

>>> p1 = Protective(3)
>>> p1.protected_value
3
>>> p1 = Protective(5.0)
>>> p1.protected_value
5
>>> p2 = Protective(-5)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 3, in __init__
  File "<stdin>", line 15, in protected_value
ValueError: protectected_value must be between 0 and 100 inclusive
>>> p1.protected_value = 7.3
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 17, in protected_value
TypeError: protected_value must be an integer
>>> p1.protected_value = 101
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 15, in protected_value
ValueError: protectected_value must be between 0 and 100 inclusive
>>> del p1.protected_value
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 18, in protected_value
AttributeError: do not delete, protected_value can be set to 0

Do the names matter?

Yes they do. .setter and .deleter make copies of the original property. This allows subclasses to properly modify behavior without altering the behavior in the parent.

class Obj:
    """property demo"""
    #
    @property
    def get_only(self):
        return self._attribute
    #
    @get_only.setter
    def get_or_set(self, value):
        self._attribute = value
    #
    @get_or_set.deleter
    def get_set_or_delete(self):
        del self._attribute

Now for this to work, you have to use the respective names:

obj = Obj()
# obj.get_only = 'value' # would error
obj.get_or_set = 'value'  
obj.get_set_or_delete = 'new value'
the_value = obj.get_only
del obj.get_set_or_delete
# del obj.get_or_set # would error

I'm not sure where this would be useful, but the use-case is if you want a get, set, and/or delete-only property. Probably best to stick to semantically same property having the same name.

Conclusion

Start with simple attributes.

If you later need functionality around the setting, getting, and deleting, you can add it with the property decorator.

Avoid functions named set_... and get_... - that's what properties are for.

If you are looking for a way to make this work without recompiling your Any CPU application, here is another potential workaround:

1. Locate your COM object GUID under the HKey_Classes_Root\Wow6432Node\CLSID\{GUID}
2. Once located add a new REG_SZ (string) Value. Name should be AppID and data should be the same COM object GUID you have just searched for
3. Add a new key under HKey_Classes_Root\Wow6432Node\AppID. The new key should be called the same as the COM object GUID.
4. Under the new key you just added, add a new String Value, and call it DllSurrogate. Leave the value empty.
5. Create a new Key under HKey_Local_Machine\Software\Classes\AppID\ Again the new key should be called the same as the COM object’s GUID. No values are necessary to be added under this key.

I take no credit for the solution, but it worked for us. Check the source link for more information and other comments.

First of all, you should make an HTML form containing a file input element. You also need to set the form's enctype attribute to multipart/form-data:

<form method="post" enctype="multipart/form-data" action="/upload">
    <input type="file" name="file">
    <input type="submit" value="Submit">
</form>

Assuming the form is defined in index.html stored in a directory named public relative to where your script is located, you can serve it this way:

const http = require("http");
const path = require("path");
const fs = require("fs");

const express = require("express");

const app = express();
const httpServer = http.createServer(app);

const PORT = process.env.PORT || 3000;

httpServer.listen(PORT, () => {
  console.log(`Server is listening on port ${PORT}`);
});

// put the HTML file containing your form in a directory named "public" (relative to where this script is located)
app.get("/", express.static(path.join(__dirname, "./public")));

Once that's done, users will be able to upload files to your server via that form. But to reassemble the uploaded file in your application, you'll need to parse the request body (as multipart form data).

In Express 3.x you could use express.bodyParser middleware to handle multipart forms but as of Express 4.x, there's no body parser bundled with the framework. Luckily, you can choose from one of the many available multipart/form-data parsers out there. Here, I'll be using multer:

You need to define a route to handle form posts:

const multer = require("multer");

const handleError = (err, res) => {
  res
    .status(500)
    .contentType("text/plain")
    .end("Oops! Something went wrong!");
};

const upload = multer({
  dest: "/path/to/temporary/directory/to/store/uploaded/files"
  // you might also want to set some limits: https://github.com/expressjs/multer#limits
});


app.post(
  "/upload",
  upload.single("file" /* name attribute of <file> element in your form */),
  (req, res) => {
    const tempPath = req.file.path;
    const targetPath = path.join(__dirname, "./uploads/image.png");

    if (path.extname(req.file.originalname).toLowerCase() === ".png") {
      fs.rename(tempPath, targetPath, err => {
        if (err) return handleError(err, res);

        res
          .status(200)
          .contentType("text/plain")
          .end("File uploaded!");
      });
    } else {
      fs.unlink(tempPath, err => {
        if (err) return handleError(err, res);

        res
          .status(403)
          .contentType("text/plain")
          .end("Only .png files are allowed!");
      });
    }
  }
);

In the example above, .png files posted to /upload will be saved to uploaded directory relative to where the script is located.

In order to show the uploaded image, assuming you already have an HTML page containing an img element:

<img src="/image.png" />

you can define another route in your express app and use res.sendFile to serve the stored image:

app.get("/image.png", (req, res) => {
  res.sendFile(path.join(__dirname, "./uploads/image.png"));
});

I used to use a Dictionary which is some sort of an indexed list which will give me exactly what I want when I want it.

Dictionary<string, int> margins = new Dictionary<string, int>();
margins.Add("left", 10);
margins.Add("right", 10);
margins.Add("top", 20);
margins.Add("bottom", 30);

Whenever I wish to access my margins values, for instance, I address my dictionary:

int xStartPos = margins["left"];
int xLimitPos = margins["right"];
int yStartPos = margins["top"];
int yLimitPos = margins["bottom"];

So, depending on what you're doing, a dictionary can be useful.

Just update your eclipse.ini file (you can find it in the root-directory of eclipse) by this:

-vm
path/javaw.exe

for example:

-vm 
C:/Program Files/Java/jdk1.7.0_09/jre/bin/javaw.exe

In Bourne shell(sh), use the . command to source a file

. filename

TextView tvCompany = (TextView)findViewById(R.layout.tvCompany);
tvCompany.setTypeface(null,Typeface.BOLD);

You an set it from code. Typeface

just wanna add another easy way to do this: If your ImageButton remains its background and you don't set it to null, it will work like a normal button and will show the click animation while clicking exactly like other buttons.The way to hide the background while it is still there:

<ImageButton
    android:id="@+id/imageButton2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingBottom="1dp"
    android:paddingLeft="1dp"
    android:paddingRight="1dp"
    android:paddingTop="1dp"
    android:src="@drawable/squareicon" />

The paddings won't let the background be visible and make the button act like other buttons.

If you're looking to make the elements be 33.3% only on small devices and lower:

This is backwards from what Bootstrap is designed for, but you can do this:

<div class="row">
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
    <div class="col-xs-4 col-md-12">.col-xs-4 .col-md-12</div>
</div>

This will make each element 33.3% wide on small and extra small devices but 100% wide on medium and larger devices.

JSFiddle: http://jsfiddle.net/jdwire/sggt8/embedded/result/

If you're only looking to hide elements for smaller devices:

I think you're looking for the visible-xs and/or visible-sm classes. These will let you make certain elements only visible to small screen devices.

For example, if you want a element to only be visible to small and extra-small devices, do this:

<div class="visible-xs visible-sm">You're using a fairly small device.</div>

To show it only for larger screens, use this:

<div class="hidden-xs hidden-sm">You're probably not using a phone.</div>

See http://getbootstrap.com/css/#responsive-utilities-classes for more information.

I have went through most of the answers and im pretty sure that it's unachievable. Whatever you try to divide two int into double or float is not gonna happen. But you have tons of methods to make the calculation happen, just cast them into float or double before the calculation will be fine.

Adding to @MK Yung and @Bruno's answer.. Do enter a password for the destination keystore. I saw my console hanging when I entered the command without a password.

openssl pkcs12 -export -in abc.crt -inkey abc.key -out abc.p12 -name localhost  -passout pass:changeit

WAMP: acronym for Windows Operating System, Apache(Web server), MySQL Database and PHP Language.

XAMPP: acronym for X (any Operating System), Apache (Web server), MySQL Database, PHP Language and PERL.

XAMPP and WampServer are both free packages of WAMP, with additional applications/tools, put together by different people.

Their differences are in the format/structure of the package, the configurations, and the included management applications.

In short: XAMPP supports more OSes and includes more features

Change

Range(DataImportColumn & DataImportRow).Offset(0, 2).Value

to

Cells(DataImportRow,DataImportColumn).Value

When you just have the row and the column then you can use the cells() object. The syntax is Cells(Row,Column)

Also one more tip. You might want to fully qualify your Cells object. for example

ThisWorkbook.Sheets("WhatEver").Cells(DataImportRow,DataImportColumn).Value

This is a recursive version that works with letter drives as well as UNC. I used the error catching to implement it but if anyone can do one without, I would be interested to see it. This approach works from the branches to the root so it will be somewhat usable when you don't have permissions in the root and lower parts of the directory tree.

' Reverse create directory path. This will create the directory tree from the top    down to the root.
' Useful when working on network drives where you may not have access to the directories close to the root
Sub RevCreateDir(strCheckPath As String)
    On Error GoTo goUpOneDir:
    If Len(Dir(strCheckPath, vbDirectory)) = 0 And Len(strCheckPath) > 2 Then
        MkDir strCheckPath
    End If
    Exit Sub
' Only go up the tree if error code Path not found (76).
goUpOneDir:
    If Err.Number = 76 Then
        Call RevCreateDir(Left(strCheckPath, InStrRev(strCheckPath, "\") - 1))
        Call RevCreateDir(strCheckPath)
    End If
End Sub

Sometimes you have to use @import as opposed to inline . If you are working on a complex application that has 32 or more css files and you must support IE9 there is no choice. IE9 ignores any css file after the first 31 and this includes and inline css. However, each sheet can import 31 others.

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

I had similar issue due to a small mistake, when i was trying to convert a List to json. If a List is converted to json it will return JSONArray not JSONObject.

You need to set the "linker search paths" of the project (for both Debug and Release builds). If this library was in, say, a sibling directory to the project then you can set it like this:

$(PROJECT_DIR)/../GoogleAnalytics/lib

(you want to avoid using an absolute path, instead keep the library directory relative to the project).
