I fought with this problem for a few hours before stumbling on the obvious answer. The problem I had was I was using different ssh implementations between when I generated my keys and when I used git.

I used ssh-keygen from the command prompt to generate my keys and but when I tried "git clone ssh://..." I got the same results as you, a prompt for the password and the message "fatal: The remote end hung up unexpectedly".

Determine which ssh windows is using by executing the Windows "where" command.

C:\where ssh
C:\Program Files (x86)\Git\bin\ssh.exe

The second line tells you which exact program will be executed.

Next you need to determine which ssh that git is using. Find this by:

C:\set GIT_SSH
GIT_SSH=C:\Program Files\TortoiseSVN\bin\TortoisePlink.exe

And now you see the problem.

To correct this simply execute:

C:\set GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe

To check if changes are applied:

C:\set GIT_SSH
GIT_SSH=C:\Program Files (x86)\Git\bin\ssh.exe

Now git will be able to use the keys that you generated earlier.

This fix is so far only for the current window. To fix it completely you need to change your environment variable.

1. Open Windows explorer
2. Right-click Computer and select Properties
3. Click Advanced System Settings link on the left
4. Click the Environment Variables... button
5. In the system variables section select the GIT_SSH variable and press the Edit... button
6. Update the variable value.
7. Press OK to close all windows

Now any future command windows you open will have the correct settings.

Hope this helps.

GNU make is available on chocolatey.

• Install chocolatey from here.

• Then, choco install make.

Now you will be able to use Make on windows.

I started powershell on a running microsoft/iis run as daemon using

I would like to add a bit more to MadProgrammer's Answer.

In case of multiple line writing, when executing the command

writer.write(string);

one may notice that the newline characters are omitted or skipped in the written file even though they appear during debugging or if the same text is printed onto the terminal with,

System.out.println("\n");

Thus, the whole text comes as one big chunk of text which is undesirable in most cases. The newline character can be dependent on the platform, so it is better to get this character from the java system properties using

String newline = System.getProperty("line.separator");

and then using the newline variable instead of "\n". This will get the output in the way you want it.

There are 2 version of the Java Environments, J2EE and Se. SE is the standard edition, which includes all the basic classes that you would need to write single user applications. While the Enterprise Edition is set up for multi-tiered enterprise applications, or possible distributed applications. If you'd be using app servers, like tomcat or websphere, you'd want to use the J2EE, with the extra classes for n-tier support.

Getting one month ago is easy with a single MySQL function:

SELECT DATE_SUB(NOW(), INTERVAL 1 MONTH);

or

SELECT NOW() - INTERVAL 1 MONTH;

Off the top of my head, I can't think of an elegant way to get the first day of last month in MySQL, but this will certainly work:

SELECT CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01');

Put them together and you get a query that solves your problem:

SELECT *
FROM your_table
WHERE t >= CONCAT(LEFT(NOW() - INTERVAL 1 MONTH,7),'-01')
AND t <= NOW() - INTERVAL 1 MONTH

The fact that Clang compiles code faster may not be as important as the speed of the resulting binary. However, here is a series of benchmarks.

None of these answers properly handle tabs, newlines, carriage returns, and some don't handle extended ASCII and unicode. This will KEEP tabs & newlines, but remove control characters and anything out of the ASCII set. Click "Run this code snippet" button to test. There is some new javascript coming down the pipe so in the future (2020+?) you may have to do \u{FFFFF} but not yet

console.log("line 1\nline2 \n\ttabbed\nF??^?¯?^??????????????l????~¨??????_??????a?????"????????????v?¯?????i????o?????????????????????".replace(/[\x00-\x08\x0E-\x1F\x7F-\uFFFF]/g, ''))

Are you using .NET 3.5? Create an IsNull extension method:

public static bool IsNull(this object input)
{
    input == null ? return true : return false;
}

public void Main()

   object x = new object();
   if(x.IsNull)
   {
      //do your thing
   }
}

If you can't use form, another approach with downloadjs fit nice. Downloadjs use blob and html 5 file API under the hood:

<div onClick=(()=>{downloadjs(url, filename)})/>

*it's jsx/react syntax, but can be used in pure html

"Knowing about sites which handles such massive traffic gives lots of pointers for architects etc. to keep in mind certain stuff while designing new sites"

I think you can probably learn a lot from the design of Facebook, just as you can from the design of any successful large software system. However, it seems to me that you should not keep the current design of Facebook in mind when designing new systems.

Why do you want to be able to handle the traffic that Facebook has to handle? Odds are that you will never have to, no matter how talented a programmer you may be. Facebook itself was not designed from the start for such massive scalability, which is perhaps the most important lesson to learn from it.

If you want to learn about a non-trivial software system I can recommend the book "Dissecting a C# Application" about the development of the SharpDevelop IDE. It is out of print, but it is available for free online. The book gives you a glimpse into a real application and provides insights about IDEs which are useful for a programmer.

When the using() for your StreamReader is ending, it's disposing the object and closing the stream, which your StreamWriter is still trying to use.

There's no way to evaluate multiple values in one 'case'. You could either use an if statement (as others have suggested) or call a method which evaluates the range that the integer belongs to and returns a value which represents that range (such as "minor", "adult", etc.), then evaluate this returned value in the switch statement. Of course, you'd probably still be using an if statement in the custom method.

In Addition to @Dev Blanked answer, if you want to use an existing bean that was created by Spring the code can be modified to:

@RunWith(MockitoJUnitRunner.class)
public class DemoTest {

    @Inject
    private ApplicationContext ctx;

    @Spy
    private SomeService service;

    @InjectMocks
    private Demo demo;

    @Before
    public void setUp(){
        service = ctx.getBean(SomeService.class);
    }

    /* ... */
}

This way you don't need to change your code (add another constructor) just to make the tests work.

You can make the import command from any SQL query browser using the following command:

source C:\path\to\file\dump.sql

Run the above code in the query window ... and wait a while :)

This is more or less equal to the previously stated command line version. The main difference is that it is executed from within MySQL instead. For those using non-standard encodings, this is also safer than using the command line version because of less risk of encoding failures.

you can return 2 or more values to a function in VBA or any other visual basic stuff but you need to use the pointer method called Byref. See my example below. I will make a function to add and subtract 2 values say 5,6

sub Macro1
    ' now you call the function this way
    dim o1 as integer, o2 as integer
    AddSubtract 5, 6, o1, o2
    msgbox o2
    msgbox o1
end sub


function AddSubtract(a as integer, b as integer, ByRef sum as integer, ByRef dif as integer)
    sum = a + b
    dif = b - 1
end function

You shouldn't blindly trust everything posted on stackoverflow. The comment in Jens code is incorrect, the parameter doesn't control whether exceptions are thrown or not.

MSDN is very clear what that parameter controls, have you read it? http://msdn.microsoft.com/en-us/library/dd321703(v=vs.110).aspx

If throwOnFirstException is true, an exception will immediately propagate out of the call to Cancel, preventing the remaining callbacks and cancelable operations from being processed. If throwOnFirstException is false, this overload will aggregate any exceptions thrown into an AggregateException, such that one callback throwing an exception will not prevent other registered callbacks from being executed.

The variable name is also wrong because Cancel is called on CancellationTokenSource not the token itself and the source changes state of each token it manages.

As Matt has said, use Console.Write. I would also recommend explicitly flushing the output, however - I believe WriteLine does this automatically, but I'd seen oddities when just using Console.Write and then waiting. So Matt's code becomes:

Console.Write("What is your name? ");
Console.Out.Flush();
var name = Console.ReadLine();

If anyone's still looking for a solution to this, I found an answer at How to play ringtone/alarm sound in Android

try {
    Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    Ringtone r = RingtoneManager.getRingtone(getApplicationContext(), notification);
    r.play();
} catch (Exception e) {
    e.printStackTrace();
}

You can change TYPE_NOTIFICATION to TYPE_ALARM, but you'll want to keep track of your Ringtone r in order to stop playing it... say, when the user clicks a button or something.

Open terminal. Type the following

echo>sure.sh
chmod 700 sure.sh

Paste this inside sure.sh

#!\bin\bash

echo -n 'Are you sure? [Y/n] '
read yn

if [ "$yn" = "n" ]; then
    exit 1
fi

exit 0

Close sure.sh and type this in terminal.

alias sure='~/sure&&'

Now, if you type sure before typing the command it will give you an are you sure prompt before continuing the command.

Hope this is helpful!

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

This example works great.

<button onclick="genPDF()">Generate PDF</button>

        var doc = new jsPDF();
        doc.text(20, 20, 'Hello world!');
        doc.text(20, 30, 'This is client-side Javascript, pumping out a PDF.');
        doc.addPage();
        doc.text(20, 20, 'Do you like that?');
    
        doc.save('Test.pdf');
    }
</script>

According to the documentation of the Item property:

Sets or returns an item for a specified key in a Dictionary object.

In your case, you don't have an item whose key is 1 so doing:

s = d.Item(i)

actually creates a new key / value pair in your dictionary, and the value is empty because you have not used the optional newItem argument.

The Dictionary also has the Items method which allows looping over the indices:

a = d.Items
For i = 0 To d.Count - 1
    s = a(i)
Next i

Henrik is on the right track. The 'foreach' command can execute any arbitrary shell script. Two options to pull the very latest might be,

git submodule foreach git pull origin master

and,

git submodule foreach /path/to/some/cool/script.sh

That will iterate through all initialized submodules and run the given commands.

Package & install are various phases in maven build lifecycle. package phase will execute all phases prior to that & it will stop with packaging the project as a jar. Similarly install phase will execute all prior phases & finally install the project locally for other dependent projects.

For understanding maven build lifecycle please go through the following link https://ayolajayamaha.blogspot.in/2014/05/difference-between-mvn-clean-install.html

Just Change in build.gradle file

 classpath 'com.android.tools.build:gradle:1.3.0'

To

 classpath 'com.android.tools.build:gradle:2.0.0'

1. Now GoTo -> menu choose File -> Invalidate Caches/Restart...

2. Choose first option: Invalidate and Restart

   Android Studio would restart.

   After this, it should work normally.

Instead of

<div class="col-md-4"></div>
<div class="col-md-4"></div>
<div class="col-md-4"></div>

You could just use

<div class="col-md-4 col-md-offset-4"></div>

As long as you don't want anything in columns 1 & 3 this is a more elegant solution. The offset "adds" 4 columns in front, leaving you with 4 "spare" after.

PS I realise that the initial question specifies no offsets but at least one previous answer uses a CSS hack that is unnecessary if you use offsets. So for completeness' sake I think this is valid.

mButton.setBackgroundColor(getResources().getColor(R.color.myColor));

You can also move mounted out of the Vue instance and make it a function in the top-level scope. This is also a useful trick for server side rendering in Vue.

function init() {
  // Use `this` normally
}

new Vue({
  methods:{
    init
  },
  mounted(){
    init.call(this)
  }
})

you can use git status -uno to check if your local branch is up-to-date with the origin one.

It works if you remove flexDirection: row from descriptionContainerVer and descriptionContainerVer2 respectively.

UPDATE (see comments)

I made a few changes to achieve what I think you're after. First of all I removed the descriptionContainerHor component. Then I set the flexDirection of the vertical views to row and added alignItems: 'center' and justifyContent: 'center'. Since the vertical views are now in fact stacked along the horizontal axis I removed the Ver part from the name.

So now you have a wrapper view that should vertically and horizontally align it's content and stack it along the x-axis. I then simply put two invisible View components on the left and right side of the Text component to do the padding.

Like this:

<View style={styles.descriptionContainer}>
  <View style={styles.padding}/>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Here is a really long text that you can do nothing about, its gonna be long wether you like it or not, so be prepared for it to go off screen. Right? Right..!
    </Text>
  <View style={styles.padding}/>
</View>

And this:

descriptionContainer:{
  flex:0.5, //height (according to its parent),
  flexDirection: 'row',
  backgroundColor: 'blue',
  alignItems: 'center',
  justifyContent: 'center',
  // alignSelf: 'center',
},
padding: {
  flex: 0.1
},
descriptionText: {
  backgroundColor: 'green',//Colors.transparentColor,
  fontSize: 16,
  flex: 0.8,
  color: 'white',
  textAlign: 'center',
  flexWrap: 'wrap'
},

Then you get what I believe you were after.

FURTHER IMPROVEMENTS

Now if you would like to stack multiple text areas within the blue and orange views you can do something like this:

<View style={styles.descriptionContainer2}>
  <View style={styles.padding}/>
  <View style={styles.textWrap}>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Some other long text which you can still do nothing about.. Off the screen we go then.
    </Text>
    <Text style={styles.descriptionText} numberOfLines={5} >
      Another column of text.
    </Text>
  </View>
  <View style={styles.padding}/>
</View>

Where textWrapis styled like this:

textWrap: {
  flexDirection: 'column',
  flex: 0.8
},

Hope this helps!

I had similar situation like Hobhouse. I wanted to use command

 ssh myhost.com 'some_command'

and 'some_command' exists in '/var/some_location' so I tried to append '/var/some_location' in PATH environment by editing '$HOME/.bashrc'

but that wasn't working. because default .bashrc(Ubuntu 10.4 LTS) prevent from sourcing by code like below

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

so If you want to change environment for ssh non-login shell. you should add code above that line.

Should you also need the parameters:

current_fullpath = request.env['ORIGINAL_FULLPATH']
# If you are browsing http://example.com/my/test/path?param_n=N 
# then current_fullpath will point to "/my/test/path?param_n=N"

And remember you can always call <%= debug request.env %> in a view to see all the available options.

Using Native Query:

Query query = entityManager.createNativeQuery("SELECT projectId, projectName FROM projects");
List result = query.getResultList();

If everyone agrees that

1. return is not necessary at the end of a function's body
2. not using return is marginally faster (according to @Alan's test, 4.3 microseconds versus 5.1)

should we all stop using return at the end of a function? I certainly won't, and I'd like to explain why. I hope to hear if other people share my opinion. And I apologize if it is not a straight answer to the OP, but more like a long subjective comment.

My main problem with not using return is that, as Paul pointed out, there are other places in a function's body where you may need it. And if you are forced to use return somewhere in the middle of your function, why not make all return statements explicit? I hate being inconsistent. Also I think the code reads better; one can scan the function and easily see all exit points and values.

Paul used this example:

foo = function() {
 if(a) {
   return(a)
 } else {
   return(b)
 }
}

Unfortunately, one could point out that it can easily be rewritten as:

foo = function() {
 if(a) {
   output <- a
 } else {
   output <- b
 }
output
}

The latter version even conforms with some programming coding standards that advocate one return statement per function. I think a better example could have been:

bar <- function() {
   while (a) {
      do_stuff
      for (b) {
         do_stuff
         if (c) return(1)
         for (d) {
            do_stuff
            if (e) return(2)
         }
      }
   }
   return(3)
}

This would be much harder to rewrite using a single return statement: it would need multiple breaks and an intricate system of boolean variables for propagating them. All this to say that the single return rule does not play well with R. So if you are going to need to use return in some places of your function's body, why not be consistent and use it everywhere?

I don't think the speed argument is a valid one. A 0.8 microsecond difference is nothing when you start looking at functions that actually do something. The last thing I can see is that it is less typing but hey, I'm not lazy.

The short version is: The efficient way to use readlines() is to not use it. Ever.

I read some doc notes on readlines(), where people has claimed that this readlines() reads whole file content into memory and hence generally consumes more memory compared to readline() or read().

The documentation for readlines() explicitly guarantees that it reads the whole file into memory, and parses it into lines, and builds a list full of strings out of those lines.

But the documentation for read() likewise guarantees that it reads the whole file into memory, and builds a string, so that doesn't help.

On top of using more memory, this also means you can't do any work until the whole thing is read. If you alternate reading and processing in even the most naive way, you will benefit from at least some pipelining (thanks to the OS disk cache, DMA, CPU pipeline, etc.), so you will be working on one batch while the next batch is being read. But if you force the computer to read the whole file in, then parse the whole file, then run your code, you only get one region of overlapping work for the entire file, instead of one region of overlapping work per read.

You can work around this in three ways:

1. Write a loop around readlines(sizehint), read(size), or readline().
2. Just use the file as a lazy iterator without calling any of these.
3. mmap the file, which allows you to treat it as a giant string without first reading it in.

For example, this has to read all of foo at once:

with open('foo') as f:
    lines = f.readlines()
    for line in lines:
        pass

But this only reads about 8K at a time:

with open('foo') as f:
    while True:
        lines = f.readlines(8192)
        if not lines:
            break
        for line in lines:
            pass

And this only reads one line at a time—although Python is allowed to (and will) pick a nice buffer size to make things faster.

with open('foo') as f:
    while True:
        line = f.readline()
        if not line:
            break
        pass

And this will do the exact same thing as the previous:

with open('foo') as f:
    for line in f:
        pass

Meanwhile:

but should the garbage collector automatically clear that loaded content from memory at the end of my loop, hence at any instant my memory should have only the contents of my currently processed file right ?

Python doesn't make any such guarantees about garbage collection.

The CPython implementation happens to use refcounting for GC, which means that in your code, as soon as file_content gets rebound or goes away, the giant list of strings, and all of the strings within it, will be freed to the freelist, meaning the same memory can be reused again for your next pass.

However, all those allocations, copies, and deallocations aren't free—it's much faster to not do them than to do them.

On top of that, having your strings scattered across a large swath of memory instead of reusing the same small chunk of memory over and over hurts your cache behavior.

Plus, while the memory usage may be constant (or, rather, linear in the size of your largest file, rather than in the sum of your file sizes), that rush of mallocs to expand it the first time will be one of the slowest things you do (which also makes it much harder to do performance comparisons).

Putting it all together, here's how I'd write your program:

for filename in os.listdir(input_dir):
    with open(filename, 'rb') as f:
        if filename.endswith(".gz"):
            f = gzip.open(fileobj=f)
        words = (line.split(delimiter) for line in f)
        ... my logic ...  

Or, maybe:

for filename in os.listdir(input_dir):
    if filename.endswith(".gz"):
        f = gzip.open(filename, 'rb')
    else:
        f = open(filename, 'rb')
    with contextlib.closing(f):
        words = (line.split(delimiter) for line in f)
        ... my logic ...

You could use the INDIRECT function. This takes a string and converts it into a range

More info here

=INDIRECT("K"&A2)

But it's preferable to use INDEX as it is less volatile.

=INDEX(K:K,A2)

This returns a value or the reference to a value from within a table or range

More info here

Put either function into cell B2 and fill down.

You can assign an iterable to side_effect, and the mock will return the next value in the sequence each time it is called:

>>> from unittest.mock import Mock
>>> m = Mock()
>>> m.side_effect = ['foo', 'bar', 'baz']
>>> m()
'foo'
>>> m()
'bar'
>>> m()
'baz'

Quoting the Mock() documentation:

If side_effect is an iterable then each call to the mock will return the next value from the iterable.

The Exception means that the socket was closed unexpectedly from the other side. Since you are calling a web service, this should not happen - most likely you're sending a request that triggers a bug in the web service.

Try logging the entire request in those cases, and see if you notice anything unusual. Otherwise, get in contact with the web service provider and send them your logged problematical request.

This function should handle multidimensional arrays along with multiple elements with the same name.

I've been using it for a couple years so far:

jQuery.fn.serializeJSON=function() {
  var json = {};
  jQuery.map(jQuery(this).serializeArray(), function(n, i) {
    var _ = n.name.indexOf('[');
    if (_ > -1) {
      var o = json;
      _name = n.name.replace(/\]/gi, '').split('[');
      for (var i=0, len=_name.length; i<len; i++) {
        if (i == len-1) {
          if (o[_name[i]]) {
            if (typeof o[_name[i]] == 'string') {
              o[_name[i]] = [o[_name[i]]];
            }
            o[_name[i]].push(n.value);
          }

        json[n.name].push(n.value || '');

Use print("use this bracket -sample text")

In Python 3 print "Hello world" gives invalid syntax error.

To display string content in Python3 have to use this ("Hello world") brackets.

Prefix you literal with 0b like in

int i = 0b11111111;

See here.

Note : This function will ignore the numbers after the decimal mean dot, If you wanna count with decimal then remove the Math.floor(). Direct to the point check this out!

function digitCount ( num )
{
     return Math.floor( num.toString()).length;
}

 digitCount(2343) ;

// ES5+

 const digitCount2 = num => String( Math.floor( Math.abs(num) ) ).length;

 console.log(digitCount2(3343))

Basically What's going on here. toString() and String() same build-in function for converting digit to string, once we converted then we'll find the length of the string by build-in function length.

Alert: But this function wouldn't work properly for negative number, if you're trying to play with negative number then check this answer Or simple put Math.abs() in it;

Cheer You!

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } });

Following up to @steven-anderson you can also configure passwords inside the ant.properties, so the process can be fully automated

so if you put in platform\android\ant.properties the following

key.store=../../yourCertificate.jks
key.store.password=notSoSecretPassword
key.alias=userAlias
key.alias.password=notSoSecretPassword

I use inf/-inf as initial values to find minimum/maximum value of a measurement. Lets say that you measure temperature with a sensor and you want to keep track of minimum/maximum temperature. The sensor might provide a valid temperature or might be broken. Pseudocode:

# initial value of the temperature
t = float('nan')          
# initial value of minimum temperature, so any measured temp. will be smaller
t_min = float('inf')      
# initial value of maximum temperature, so any measured temp. will be bigger
t_max = float('-inf')     
while True:
    # measure temperature, if sensor is broken t is not changed
    t = measure()     
    # find new minimum temperature
    t_min = min(t_min, t) 
    # find new maximum temperature
    t_max = max(t_max, t) 

The above code works because inf/-inf/nan are valid for min/max operation, so there is no need to deal with exceptions.

Or a nested List (okay, the OP was for a single column and this is for multiple columns..):

        //Base list is a list of fields, ie a data record
        //Enclosing list is then a list of those records, ie the Result set
        List<List<String>> ResultSet = new List<List<String>>();

        using (SqlConnection connection =
            new SqlConnection(connectionString))
        {
            // Create the Command and Parameter objects.
            SqlCommand command = new SqlCommand(qString, connection);

            // Create and execute the DataReader..
            connection.Open();
            SqlDataReader reader = command.ExecuteReader();
            while (reader.Read())
            {
                var rec = new List<string>();
                for (int i = 0; i <= reader.FieldCount-1; i++) //The mathematical formula for reading the next fields must be <=
                {                      
                    rec.Add(reader.GetString(i));
                }
                ResultSet.Add(rec);

            }
        }

In order to ignore untracked files especially if they are located in (a few) folders that are not tracked, a simple solution is to add a .gitignore file to every untracked folder and enter in a single line containing * followed by a new line. It's a really simple and straightforward solution if the untracked files are in a few folders. For me, all files were coming from a single untracked folder vendor and the above just worked.

Using @Jarda's guide you can define this if you need to set the variable the same value for all tests:

@Before
public void setClientMapper() throws NoSuchFieldException, SecurityException{
    FieldSetter.setField(client, client.getClass().getDeclaredField("mapper"), new Mapper());
}

But beware that setting private values to be different should be handled with care. If they are private are for some reason.

Example, I use it, for example, to change the wait time of a sleep in the unit tests. In real examples I want to sleep for 10 seconds but in unit-test I'm satisfied if it's immediate. In integration tests you should test the real value.

If you just want to kill any/all java processes, then all you need is;

killall java

If, however, you want to kill the wskInterface process in particular, then you're most of the way there, you just need to strip out the process id;

PID=`ps -ef | grep wskInterface | awk '{ print $2 }'`
kill -9 $PID

Should do it, there is probably an easier way though...

Your question was already answered by the other posters, I'd just like to point out that

 delete from table where id <> 2

(or variants thereof, not id = 2 etc) will not delete rows where id is NULL.

If you also want to delete rows with id = NULL:

delete from table where id <> 2 or id is NULL

To get your current location as start point you need to use this URL:

https://www.google.com/maps/dir/?api=1&origin=Current+Location&destination=<latitude>,<longitude>

You can fill up the destination parameter with the address, name or latitude and longitude values.

You can only accomplish this with PHP comments.

 <!-- <tr>
      <td><?php //echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php //echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php //echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php //echo $sort_order; ?>" size="1" /></td>
    </tr> -->

The way that PHP and HTML works, it is not able to comment in one swoop unless you do:

<?php

/*

echo <<<ENDHTML
 <tr>
          <td>{$entry_keyword}</td>
          <td><input type="text" name="keyword" value="{echo $keyword}" /></td>
        </tr>
        <tr>
          <td>{$entry_sort_order}</td>
          <td><input name="sort_order" value="{$sort_order}" size="1" /></td>
        </tr>
ENDHTML;

*/
?>

FAQ says:

If you have

varname <- c("a", "b", "d")

you can do

get(varname[1]) + 2

for

a + 2

or

assign(varname[1], 2 + 2)

for

a <- 2 + 2

So it looks like you use GET when you want to evaluate a formula that uses a variable (such as a concatenate), and ASSIGN when you want to assign a value to a pre-declared variable.

Syntax for assign: assign(x, value)

x: a variable name, given as a character string. No coercion is done, and the first element of a character vector of length greater than one will be used, with a warning.

value: value to be assigned to x.

For this you need to update your Project Facets setting.

Project (right click) -> Properties -> Project Facets from left navigation.

If it is not open...click on the link, Check the Dynamic Web Module Check Box and select the respective version (Probably 2.4). Click on Apply Button and then Click on OK.

Use Math.Round(double);

I have used it myself. It actually rounds off the decimal places.

d = 19.82;
ans = Math.round(d);
System.out.println(ans);
// Output : 20 

d = 19.33;
ans = Math.round(d);
System.out.println(ans);
// Output : 19 

Hope it Helps :-)

The static factory method pattern is a way to encapsulate object creation. Without a factory method, you would simply call the class's constructor directly: Foo x = new Foo(). With this pattern, you would instead call the factory method: Foo x = Foo.create(). The constructors are marked private, so they cannot be called except from inside the class, and the factory method is marked as static so that it can be called without first having an object.

There are a few advantages to this pattern. One is that the factory can choose from many subclasses (or implementers of an interface) and return that. This way the caller can specify the behavior desired via parameters, without having to know or understand a potentially complex class hierarchy.

Another advantage is, as Matthew and James have pointed out, controlling access to a limited resource such as connections. This a way to implement pools of reusable objects - instead of building, using, and tearing down an object, if the construction and destruction are expensive processes it might make more sense to build them once and recycle them. The factory method can return an existing, unused instantiated object if it has one, or construct one if the object count is below some lower threshold, or throw an exception or return null if it's above the upper threshold.

As per the article on Wikipedia, multiple factory methods also allow different interpretations of similar argument types. Normally the constructor has the same name as the class, which means that you can only have one constructor with a given signature. Factories are not so constrained, which means you can have two different methods that accept the same argument types:

Coordinate c = Coordinate.createFromCartesian(double x, double y)

and

Coordinate c = Coordinate.createFromPolar(double distance, double angle)

This can also be used to improve readability, as Rasmus notes.

I had this issue with code that I copied from a blog. I got rid of the issue on PyCharm by Shift+Tab'ing(unindenting) the last error-throwing code-block all the way to the left, and then Tab'ing it back to where it was. I suppose is somehow indirectly working the same as the 'reformat code' comment above.

glibc provides backtrace() function.

I wanted to store a post in my application, so I created a controller of posts (PostsController) with the resources included:

php artisan make:controller PostsController --resource

The controller was created with all the methods needed to do a CRUD app, then I added the following code to the web.php in the routes folder :

Route::resource('posts', 'PostsController');

I solved the form action problem by doing this:

1. I checked my routing list by doing php artisan route:list
2. I searched for the route name of the store method in the result table in the terminal and I found it under the name of posts.store
3. I added this to the action attribute of my form: action="{{route('posts.store')}}" instead of action="??what to write here??"

Try to explain this question in a level referring to a little bit technology

Take MongoDB and Traditional SQL for comparison, imagine the scenario of posting a Tweet on Twitter. This tweet contains 9 pictures. How do you store this tweet and its corresponding pictures?

In terms of traditional relationship SQL, you can store the tweets and pictures in separate tables, and represent the connection through building a new table.

What's more, you can set a field which is an image type, and zip the 9 pictures into a binary document and store it in this field.

Using MongoDB, you could build a document like this (similar to the concept of a table in relational SQL):

{

"id":"XXX",

"user":"XXX",

"date":"xxxx-xx-xx",

"content":{

"text":"XXXX",

"picture":["p1.png","p2.png","p3.png"]

}

Therefore, in my opinion, the main difference is about how do you store the data and the storage level of the relationships between them.

In this example, the data is the tweet and the pictures. The different mechanism about storage level of relationship between them also play a important role in the difference between both.

I hope this small example helps show the difference between SQL and NoSQL (ACID and BASE).

Here's a link of picture about the goals of NoSQL from the Internet:

Python3:

import importlib.machinery

loader = importlib.machinery.SourceFileLoader('report', '/full/path/report/other_py_file.py')
handle = loader.load_module('report')

handle.mainFunction(parameter)

This method can be used to import whichever way you want in a folder structure (backwards, forwards doesn't really matter, i use absolute paths just to be sure).

There's also the more normal way of importing a python module in Python3,

import importlib
module = importlib.load_module('folder.filename')
module.function()

Kudos to Sebastian for spplying a similar answer for Python2:

import imp

foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()

I’ve built a function I use all the time for password validation and to create passwords, e.g. to store them in a MySQL database. It uses a randomly generated salt which is way more secure than using a static salt.

function secure_password($user_pwd, $multi) {

/*
    secure_password ( string $user_pwd, boolean/string $multi ) 

    *** Description: 
        This function verifies a password against a (database-) stored password's hash or
        returns $hash for a given password if $multi is set to either true or false

    *** Examples:
        // To check a password against its hash
        if(secure_password($user_password, $row['user_password'])) {
            login_function();
        } 
        // To create a password-hash
        $my_password = 'uber_sEcUrE_pass';
        $hash = secure_password($my_password, true);
        echo $hash;
*/

// Set options for encryption and build unique random hash
$crypt_options = ['cost' => 11, 'salt' => mcrypt_create_iv(22, MCRYPT_DEV_URANDOM)];
$hash = password_hash($user_pwd, PASSWORD_BCRYPT, $crypt_options);

// If $multi is not boolean check password and return validation state true/false
if($multi!==true && $multi!==false) {
    if (password_verify($user_pwd, $table_pwd = $multi)) {
        return true; // valid password
    } else {
        return false; // invalid password
    }
// If $multi is boolean return $hash
} else return $hash;

}

It's the Unicode Character 'ZERO WIDTH SPACE' (U+200B).

this character is intended for line break control; it has no width, but its presence between two characters does not prevent increased letter spacing in justification

As per the given code sample, the entity is entirely superfluous in this context. It must be inserted by some accident, most likely by a buggy editor trying to do smart things with whitespace or highlighting, or an enduser using a keyboard language wherein this character is natively been used, such as Arabic.

This is sort of done in parts in some of the other answers.

Since R2019b, there is a new command line option, -batch. It replaces -r, which is no longer recommended. It also unifies the syntax across platforms. See for example the documentation for Windows, for the other platforms the description is identical.

matlab -batch "statement to run"

This starts MATLAB without the desktop or splash screen, logs all output to stdout and stderr, exits automatically when the statement completes, and provides an exit code reporting success or error.

It is thus no longer necessary to use try/catch around the code to run, and it is no longer necessary to add an exit statement.

This just worked for me on Ubuntu 16:

Download ('instantclient-basic-linux.x64-12.2.0.1.0.zip' and 'instantclient-sdk-linux.x64-12.2.0.1.0.zip') from Oracle web site and then do following script (you can do piece by piece and I did as a ROOT):

apt-get install -y python-dev build-essential libaio1
mkdir -p /opt/ora/
cd /opt/ora/

## Now put 2 ZIP files:
# ('instantclient-basic-linux.x64-12.2.0.1.0.zip' and 'instantclient-sdk-linux.x64-12.2.0.1.0.zip') 
# into /opt/ora/ and unzip them -> both will be unzipped into 1 directory: /opt/ora/instantclient_12_2 

rm -rf /etc/profile.d/oracle.sh
echo "export ORACLE_HOME=/opt/ora/instantclient_12_2"  >> /etc/profile.d/oracle.sh
echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME"  >> /etc/profile.d/oracle.sh
chmod 777 /etc/profile.d/oracle.sh
source /etc/profile.d/oracle.sh
env | grep -i ora  # This will check current ENVIRONMENT settings for Oracle


rm -rf /etc/ld.so.conf.d/oracle.conf
echo "/opt/ora/instantclient_12_2" >> /etc/ld.so.conf.d/oracle.conf
ldconfig
cd $ORACLE_HOME  
ls -lrth libclntsh*   # This will show which version of 'libclntsh' you have... --> needed for following line:

ln -s libclntsh.so.12.1 libclntsh.so

pip install cx_Oracle   # Maybe not needed but I did it anyway (only pip install cx_Oracle without above steps did not work for me...)

Your python scripts are now ready to use 'cx_Oracle'... Enjoy!

I'm not sure about older versions, but from NEON onward, you can just right click on workspace and select Remove from launcher selection option.

of course this won't remove the original files. It simply removes it from the list of suggested workspaces.

Note for ES2+

Starting with ES 1.5.3 the delete-by-query API is deprecated, and is completely removed since ES 2.0

Instead of the API, the Delete By Query is now a plugin.

In order to use the Delete By Query plugin you must install the plugin on all nodes of the cluster:

sudo bin/plugin install delete-by-query

All of the nodes must be restarted after the installation.

The usage of the plugin is the same as the old API. You don't need to change anything in your queries - this plugin will just make them work.

*For complete information regarding WHY the API was removed you can read more here.

Check if there is already a Node server running on your machine and then close it.

This below code snippet for scala users :

Option 1 :

Below snippet you can add at the file level

import org.apache.log4j.{Level, Logger}
Logger.getLogger("org").setLevel(Level.WARN)

Option 2 :

Note : which will be applicable for all the application which is using spark session.

import org.apache.spark.sql.SparkSession

  private[this] implicit val spark = SparkSession.builder().master("local[*]").getOrCreate()

spark.sparkContext.setLogLevel("WARN")

Option 3 :

Note : This configuration should be added to your log4j.properties.. (could be like /etc/spark/conf/log4j.properties (where the spark installation is there) or your project folder level log4j.properties) since you are changing at module level. This will be applicable for all the application.

log4j.rootCategory=ERROR, console

IMHO, Option 1 is wise way since it can be switched off at file level.

None of the above answers worked for me so let me share my experience. I am running nginx in a docker container that has a port mapping (hostPort:containerPort) - 80:80 The above answers are giving me strange console output. Only the good old 'nmap' is working flawlessly even catching the nginx version. The command working for me is:

 nmap -sV localhost -p 80

We are doing nmap using the -ServiceVersion switch on the localhost and port: 80. It works great for me.

I think style no. 111 (Japan) should work:

SELECT CONVERT(DATETIME, '2012-08-17', 111)

And if that doesn't work for some reason - you could always just strip out the dashes and then you have the totally reliable ISO-8601 format (YYYYMMDD) which works for any language and date format setting in SQL Server:

SELECT CAST(REPLACE('2012-08-17', '-', '') AS DATETIME)

In my scenario I had a slightly different message, where the line and position were not zero.

E. Path 'job[0].name', line 1, position 12.

This was the top Google answer for the message I quoted.

This came about because I had called a program from the Windows command line, passing JSON as a parameter.

When I reviewed the args in my program, all the double quotes got stripped. You have to reconstitute them.

I posted a solution here. Though it could probably be enhanced with a Regex.

$.fn.preload = function (callback) {
  var length = this.length;
  var iterator = 0;

  return this.each(function () {
    var self = this;
    var tmp = new Image();

    if (callback) tmp.onload = function () {
      callback.call(self, 100 * ++iterator / length, iterator === length);
    };

    tmp.src = this.src;
  });
};

The usage is quite simple:

$('img').preload(function(perc, done) {
  console.log(this, perc, done);
});

Implement custom adapter for your class:

public class MyClassAdapter extends ArrayAdapter<MyClass> {

    private static class ViewHolder {
        private TextView itemView;
    }

    public MyClassAdapter(Context context, int textViewResourceId, ArrayList<MyClass> items) {
        super(context, textViewResourceId, items);
    }

    public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = LayoutInflater.from(this.getContext())
            .inflate(R.layout.listview_association, parent, false);

            viewHolder = new ViewHolder();
            viewHolder.itemView = (TextView) convertView.findViewById(R.id.ItemView);

            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        MyClass item = getItem(position);
        if (item!= null) {
            // My layout has only one TextView
                // do whatever you want with your string and long
            viewHolder.itemView.setText(String.format("%s %d", item.reason, item.long_val));
        }

        return convertView;
    }
}

For those not very familiar with the Android framework, this is explained in better detail here: https://github.com/codepath/android_guides/wiki/Using-an-ArrayAdapter-with-ListView.

Instead of explicitly writing the class name you could use

this.getClass().getResource("/unibo/lsb/res/dice.jpg");

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character

I tried the following @janny loco's answer first and then reset anaconda to get it to work.

Step 1:

activate root
conda update -n root conda
conda update --all

Step 2:

anaconda-navigator --reset

After running the update commands in step 1 and not seeing any success, I reset anaconda by running the command above based on what I found here.

I am not sure if it was the combination of updating conda and reseting the navigator or just one of the two. So, please try accordingly.

Make sure to check the schema at the database level directly. I've gotten burned by this before, where, for example, a migration was initially written to create a :datetime column, and I ran it locally, then tweaked the migration to a :date before actually deploying. Thus everyone's database looks good except for mine, and the bugs are subtle.

Android follows normal java package conventions plus here is an important snippet of text to read (this is important regarding the wide use of xml files while developing on android).

The reason for having it in reverse order is to do with the layout on the storage media. If you consider each period ('.') in the application name as a path separator, all applications from a publisher would sit together in the path hierarchy. So, for instance, packages from Adobe would be of the form:

com.adobe.reader (Adobe Reader)

com.adobe.photoshop (Adobe Photoshop)

com.adobe.ideas (Adobe Ideas)

[Note that this is just an illustration and these may not be the exact package names.]

These could internally be mapped (respectively) to:

com/adobe/reader

com/adobe/photoshop

com/adobe/ideas

The concept comes from Package Naming Conventions in Java, more about which can be read here:*

http://en.wikipedia.org/wiki/Java_package#Package_naming_conventions

Source: http://www.quora.com/Why-do-a-majority-of-Android-package-names-begin-with-com

I forgot to comment out a line with a MsgBox before executing my macro. Meaning I'd have to click OK over a hundred thousand times. The ESC key was just escaping the message box but not stopping the execution of the macro. Holding the ESC key continuously for a few seconds helped me stop the execution of the code.

Coping with different aspect ratios

The different aspect ratios seen above are (from most square; h/w):

1:1     1.0     <- rare for phone; common for watch
4:3     1.3333  <- matches iPad (when portrait)
3:2     1.5000
38:25   1.5200
14:9    1.5556  <- rare
25:16   1.5625
8:5     1.6000  <- aka 16:10
5:3     1.6667
128:75  1.7067
16:9    1.7778  <- matches iPhone 5-7
427:240 1.7792  <- rare
37:18   2.0555  <- Galaxy S8

If you skip the extreme aspect ratios, that are rarely seen at phone size or larger, all the other devices fit a range from 1.3333 to 1.7778, which conveniently matches the current iPhone/iPad ratios (considering all devices in portrait mode). Note that there are quite a few variations within that range, so if you are creating a small number of fixed aspect-ratio layouts, you will need to decide how to handle the odd "in-between" screens.

Minimum "portrait mode" solution is to support 1.3333, which results in unused space at top and bottom, on all the resolutions with larger aspect ratio.
Most likely, you would instead design it to stretch over the 1.333 to 1.778 range. But sometimes part of your design looks too distorted then.

Advanced layout ideas:

For text, you can design for 1.3333, then increase line spacing for 1.666 - though that will look quite sparse. For graphics, design for an intermediate ratio, so that on some screens it is slightly squashed, on others it is slightly stretched. geometric mean of Sqrt(1333 x 1667) ~= 1491. So you design for 1491 x 1000, which will be stretched/squashed by +-12% when assigned to the extreme cases.

Next refinement is to design layout as a stack of different-height "bands" that each fill the width of the screen. Then determine where you can most pleasingly "stretch-or-squash" a band's height, to adjust for different ratios.

For example, consider imaginary phones with 1333 x 1000 pixels and 1666 x 1000 pixels. Suppose you have two "bands", and your main "band" is square, so it is 1000 x 1000. Second band is 333 x 1000 on one screen, 666 x 1000 on the other - quite a range to design for.
You might decide your main band looks okay altered 10% up-or-down, and squash it 900 x 1000 on the 1333 x 1000 screen, leaving 433 x 1000. Then stretch it to 1100 x 1000 on 1666 x 1000 screen, leaving 566 x 1000. So your second band now needs to adjust over only 433 to 566, which has geometric mean of Sqrt(433 x 566) ~= 495. So you design for 495 x 1000, which will be stretched/squashed by +-14% when assigned to the extreme cases.

When working with buckets that have 1000+ objects its necessary to implement a solution that uses the NextContinuationToken on sequential sets of, at most, 1000 keys. This solution first compiles a list of objects then iteratively creates the specified directories and downloads the existing objects.

import boto3
import os

s3_client = boto3.client('s3')

def download_dir(prefix, local, bucket, client=s3_client):
    """
    params:
    - prefix: pattern to match in s3
    - local: local path to folder in which to place files
    - bucket: s3 bucket with target contents
    - client: initialized s3 client object
    """
    keys = []
    dirs = []
    next_token = ''
    base_kwargs = {
        'Bucket':bucket,
        'Prefix':prefix,
    }
    while next_token is not None:
        kwargs = base_kwargs.copy()
        if next_token != '':
            kwargs.update({'ContinuationToken': next_token})
        results = client.list_objects_v2(**kwargs)
        contents = results.get('Contents')
        for i in contents:
            k = i.get('Key')
            if k[-1] != '/':
                keys.append(k)
            else:
                dirs.append(k)
        next_token = results.get('NextContinuationToken')
    for d in dirs:
        dest_pathname = os.path.join(local, d)
        if not os.path.exists(os.path.dirname(dest_pathname)):
            os.makedirs(os.path.dirname(dest_pathname))
    for k in keys:
        dest_pathname = os.path.join(local, k)
        if not os.path.exists(os.path.dirname(dest_pathname)):
            os.makedirs(os.path.dirname(dest_pathname))
        client.download_file(bucket, k, dest_pathname)

Basic Differences

• A Function must return a value but in Stored Procedures it is optional: a procedure can return 0 or n values.
• Functions can have only input parameters for it, whereas procedures can have input/output parameters.
• For a Function it is mandatory to take one input parameter, but a Stored Procedure may take 0 to n input parameters.
• Functions can be called from a Procedure whereas Procedures cannot be called from a Function.

Advanced Differences

• Exceptions can be handled by try-catch blocks in a Procedure, whereas a try-catch block cannot be used in a Function.
• We can go for Transaction Management in a Procedure, whereas in a Function we can't.

In SQL:

• A Procedure allows SELECT as well as DML (INSERT, UPDATE, DELETE) statements in it, whereas Function allows only SELECT statement in it.
• Procedures can not be utilized in a SELECT statement, whereas Functions can be embedded in a SELECT statement.
• Stored Procedures cannot be used in SQL statements anywhere in a WHERE (or a HAVING or a SELECT) block, whereas Functions can.
• Functions that return tables can be treated as another Rowset. This can be used in a JOIN block with other tables.
• Inline Functions can be thought of as views that take parameters and can be used in JOIN blocks and other Rowset operations.

The easiest way is to set some variable in the file that calls include, such as

$including = true;

Then in the file that's being included, check for the variable

if (!$including) exit("direct access not permitted");

You can define sScrollX : "100%" to force dataTables to keep the column widths :

..
 sScrollX: "100%", //<-- here
 aoColumns : [
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
      { "sWidth": "100px"},
    ],
...

You can use HttpClient and HttpPost to build and send the request.

HttpClient client= new DefaultHttpClient();
HttpPost request = new HttpPost("www.example.com");

List<NameValuePair> pairs = new ArrayList<NameValuePair>();
pairs.add(new BasicNameValuePair("paramName", "paramValue"));

request.setEntity(new UrlEncodedFormEntity(pairs ));
HttpResponse resp = client.execute(request);

The line where you define lfckv is run whenever the browser finds it. When you put it into the head of your document, the browser tries to find lifecheck id before the lifecheck element is created. You must add your script below the lifecheck input in order for your code to work.

I played around with nico's answer a little and it felt jumpy. Did a bit of investigation and found window.requestAnimationFrame which is a function that is called on each repaint cycle. This allows for a more clean-looking animation. Still trying to hone in on good default values for step size but for my example things look pretty good using this implementation.

var smoothScroll = function(elementId) {
    var MIN_PIXELS_PER_STEP = 16;
    var MAX_SCROLL_STEPS = 30;
    var target = document.getElementById(elementId);
    var scrollContainer = target;
    do {
        scrollContainer = scrollContainer.parentNode;
        if (!scrollContainer) return;
        scrollContainer.scrollTop += 1;
    } while (scrollContainer.scrollTop == 0);

    var targetY = 0;
    do {
        if (target == scrollContainer) break;
        targetY += target.offsetTop;
    } while (target = target.offsetParent);

    var pixelsPerStep = Math.max(MIN_PIXELS_PER_STEP,
                                 (targetY - scrollContainer.scrollTop) / MAX_SCROLL_STEPS);

    var stepFunc = function() {
        scrollContainer.scrollTop =
            Math.min(targetY, pixelsPerStep + scrollContainer.scrollTop);

        if (scrollContainer.scrollTop >= targetY) {
            return;
        }

        window.requestAnimationFrame(stepFunc);
    };

    window.requestAnimationFrame(stepFunc);
}

Use String#trim() method or String allRemoved = myString.replaceAll("^\\s+|\\s+$", "") for trim both the end.

For left trim:

String leftRemoved = myString.replaceAll("^\\s+", "");

For right trim:

String rightRemoved = myString.replaceAll("\\s+$", "");

This solution takes punctuation into account for new sentences, handles quotations, converts minor words to lowercase and ignores acronyms or all-caps words.

var stopWordsArray = new Array("a", "all", "am", "an", "and", "any", "are", "as", "at", "be", "but", "by", "can", "can't", "did", "didn't", "do", "does", "doesn't", "don't", "else", "for", "get", "gets", "go", "got", "had", "has", "he", "he's", "her", "here", "hers", "hi", "him", "his", "how", "i'd", "i'll", "i'm", "i've", "if", "in", "is", "isn't", "it", "it's", "its", "let", "let's", "may", "me", "my", "no", "of", "off", "on", "our", "ours", "she", "so", "than", "that", "that's", "thats", "the", "their", "theirs", "them", "then", "there", "there's", "these", "they", "they'd", "they'll", "they're", "they've", "this", "those", "to", "too", "try", "until", "us", "want", "wants", "was", "wasn't", "we", "we'd", "we'll", "we're", "we've", "well", "went", "were", "weren't", "what", "what's", "when", "where", "which", "who", "who's", "whose", "why", "will", "with", "won't", "would", "yes", "yet", "you", "you'd", "you'll", "you're", "you've", "your");

        if (word == "") { return; }
        var canCapitalise = true;
        // Get the pos of the first alpha char (word might start with " or ')
        var firstAlphaCharPos = word.search(/\w/);
        // Check for uppercase char that is not the first char (might be acronym or all caps)
        if (word.search(/[A-Z]/) > 0) {

This isn't straightforward, but

SELECT CHAR(CURRENT DATE, ISO) FROM SYSIBM.SYSDUMMY1

returns the current date in yyyy-mm-dd format. You would have to substring and concatenate the result to get yyyymmdd.

SELECT SUBSTR(CHAR(CURRENT DATE, ISO), 1, 4) ||
    SUBSTR(CHAR(CURRENT DATE, ISO), 6, 2) ||
    SUBSTR(CHAR(CURRENT DATE, ISO), 9, 2)
FROM SYSIBM.SYSDUMMY1

If anyone using MS SQL Server 2008 and higher lands on this question: SQL Server 2008 and higher has a new "hierarchyId" feature designed specifically for this task.

I'm surprised that nobody has mentioned the (very old but reliable) Absolute Columns technique: http://24ways.org/2008/absolute-columns/

In my opinion, it is far superior to both Faux Columns and One True Layout's technique.

The general idea is that an element with position: absolute; will position against the nearest parent element that has position: relative;. You then stretch a column to fill 100% height by assigning both a top: 0px; and bottom: 0px; (or whatever pixels/percentages you actually need.) Here's an example:

<!DOCTYPE html>
<html>
  <head>
    <style>
      #container
      {
        position: relative;
      }

      #left-column
      {
        width: 50%;
        background-color: pink;
      }

      #right-column
      {
        position: absolute;
        top: 0px;
        right: 0px;
        bottom: 0px;
        width: 50%;
        background-color: teal;
      }
    </style>
  </head>
  <body>
    <div id="container">
      <div id="left-column">
        <ul>
          <li>Foo</li>
          <li>Bar</li>
          <li>Baz</li>
        </ul>
      </div>
      <div id="right-column">
        Lorem ipsum
      </div>
    </div>
  </body>
</html>

Make Directory savehere to be virtual directory and give read/write permission from control panel

There is the index method, i = array.index(value), but I don't think you can specify a custom comparison operator. It wouldn't be hard to write your own function to do so, though:

def custom_index(array, compare_function):
    for i, v in enumerate(array):
        if compare_function(v):
            return i

I believe using --no-index is what you're looking for:

git diff [<options>] --no-index [--] <path> <path>

as mentioned in the git manual:

This form is to compare the given two paths on the filesystem. You can omit the --no-index option when running the command in a working tree controlled by Git and at least one of the paths points outside the working tree, or when running the command outside a working tree controlled by Git.

Since my edit to Mike G's answer to modernize the code was rejected 3 to 2 as

This edit was intended to address the author of the post and makes no sense as an edit. It should have been written as a comment or an answer

I'm reposting my edit as a separate answer here. This edit removes the JSONRepresentation dependency with NSJSONSerialization as Rob's comment with 15 upvotes suggests.

    NSArray *objects = [NSArray arrayWithObjects:[[NSUserDefaults standardUserDefaults]valueForKey:@"StoreNickName"],
      [[UIDevice currentDevice] uniqueIdentifier], [dict objectForKey:@"user_question"],     nil];
    NSArray *keys = [NSArray arrayWithObjects:@"nick_name", @"UDID", @"user_question", nil];
    NSDictionary *questionDict = [NSDictionary dictionaryWithObjects:objects forKeys:keys];

    NSDictionary *jsonDict = [NSDictionary dictionaryWithObject:questionDict forKey:@"question"];

    NSLog(@"jsonRequest is %@", jsonRequest);

    NSURL *url = [NSURL URLWithString:@"https://xxxxxxx.com/questions"];

    NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];


    NSData *requestData = [NSJSONSerialization dataWithJSONObject:dict options:0 error:nil]; //TODO handle error

    [request setHTTPMethod:@"POST"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
    [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
    [request setValue:[NSString stringWithFormat:@"%d", [requestData length]] forHTTPHeaderField:@"Content-Length"];
    [request setHTTPBody: requestData];

    NSURLConnection *connection = [[NSURLConnection alloc]initWithRequest:request delegate:self];
    if (connection) {
     receivedData = [[NSMutableData data] retain];
    }

The receivedData is then handled by:

NSDictionary *jsonDict = [NSJSONSerialization JSONObjectWithData:data options:0 error:nil];
    NSDictionary *question = [jsonDict objectForKey:@"question"];

I hit the same problem on my laptop(win 10) with Wireshark(version 3.2.0), and I tried all the above solutions but unfortunately don't help.

So,

I uninstall the Wireshark bluntly and reinstall it.

After that, this problem solved.

Putting the solution here, and wish it may help someone......

Use the Application.DispatcherUnhandledException Event. See this question for a summary (see Drew Noakes' answer).

Be aware that there'll be still exceptions which preclude a successful resuming of your application, like after a stack overflow, exhausted memory, or lost network connectivity while you're trying to save to the database.

_{This more of a very important comment}

Key to understanding why vitaminwater's answer works are three things:

1. Know that UITextView is a subclass of UIScrollView class
2. Understand how ScrollView works and how its contentSize is calculated. For more see this here answer and its various solutions and comments.
3. Understand what contentSize is and how its calculated. See here and here. It might also help that setting contentOffset is likely nothing but:

func setContentOffset(offset: CGPoint)
{
    CGRect bounds = self.bounds
    bounds.origin = offset
    self.bounds = bounds
}

For more see objc scrollview and understanding scrollview

Combining the three together you'd easily understand that you need allow the the textView's intrinsic contentSize to work along AutoLayout constraints of the textView to drive the logic. It's almost as if you're textView is functioning like a UILabel

To make that happen you need to disable scrolling which basically means the scrollView's size, the contentSize's size and in case of adding a containerView, then the containerView's size would all be the same. When they're the same you have NO scrolling. And you'd have 0 contentOffset. Having 0 contentOffSet means you've not scrolled down. Not even a 1 point down! As a result the textView will be all stretched out.

It's also worth nothing that 0 contentOffset means that the scrollView's bounds and frame are identical. If you scroll down 5 points then your contentOffset would be 5, while your scrollView.bounds.origin.y - scrollView.frame.origin.y would be equal to 5

If you're checking to see if an object can respond to a series of methods, you could do something like:

methods = [:valid?, :chase, :test]

def has_methods?(something, methods)
  methods & something.methods == methods
end

the methods & something.methods will join the two arrays on their common/matching elements. something.methods includes all of the methods you're checking for, it'll equal methods. For example:

[1,2] & [1,2,3,4,5]
==> [1,2]

so

[1,2] & [1,2,3,4,5] == [1,2]
==> true

In this situation, you'd want to use symbols, because when you call .methods, it returns an array of symbols and if you used ["my", "methods"], it'd return false.

Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.

>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False

Edit

Further explanation: How does Python compare string and int?

Another way to push items into array using Mongoose is- $addToSet, if you want only unique items to be pushed into array. $push operator simply adds the object to array whether or not the object is already present, while $addToSet does that only if the object is not present in the array so as not to incorporate duplicacy.

PersonModel.update(
  { _id: person._id }, 
  { $addToSet: { friends: friend } }
);

This will look for the object you are adding to array. If found, does nothing. If not, adds it to the array.

References:

• $addToSet
• MongooseArray.prototype.addToSet()

As described by the link I've given in comment, this

$('p[MyTag]').each(function(index) {
  document.write(index + ': ' + $(this).text() + "<br>");});

works (playable example).

You can use an open source and cross-platform option: inst2xsd from Apache's XMLBeans. I find it very useful and easy.

Just download, unzip and play (it requires Java).

The "traditional" Windows equivalent would be the Protected Storage subsystem, used by IE (pre IE 7), Outlook Express, and a few other programs. I believe it's encrypted with your login password, which prevents some offline attacks, but once you're logged in, any program that wants to can read it. (See, for example, NirSoft's Protected Storage PassView.)

Windows also provides the CryptoAPI and Data Protection API that might help. Again, though, I don't think that Windows does anything to prevent processes running under the same account from seeing each other's passwords.

It looks like the book Mechanics of User Identification and Authentication provides more details on all of these.

Eclipse (via its Secure Storage feature) implements something like this, if you're interested in seeing how other software does it.

In my case a has to add my classes, when building the SessionFactory, with addAnnotationClass

Configuration configuration.configure();
StandardServiceRegistryBuilder builder = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration
            .addAnnotatedClass(MyEntity1.class)
            .addAnnotatedClass(MyEntity2.class)
            .buildSessionFactory(builder.build());

Start your node process with --inspect flag.

node --inspect index.js

Another reason to go with the short one is that it matches other instances where you might specify a character set in markup. For example:

<script type="javascript" charset="UTF-8" src="/script.js"></script>

<p><a charset="UTF-8" href="http://example.com/">Example Site</a></p>

Consistency helps to reduce errors and make code more readable.

Note that the charset attribute is case-insensitive. You can use UTF-8 or utf-8, however UTF-8 is clearer, more readable, more accurate.

Also, there is absolutely no reason at all to use any value other than UTF-8 in the meta charset attribute or page header. UTF-8 is the default encoding for Web documents since HTML4 in 1999 and the only practical way to make modern Web pages.

Also you should not use HTML entities in UTF-8. Characters like the copyright symbol should be typed directly. The only entities you should use are for the 5 reserved markup characters: less than, greater than, ampersand, prime, double prime. Entities need an HTML parser, which you may not always want to use going forward, they introduce errors, make your code less readable, increase your file sizes, and sometimes decode incorrectly in various browsers depending on which entities you used. Learn how to type/insert copyright, trademark, open quote, close quote, apostrophe, em dash, en dash, bullet, Euro, and any other characters you encounter in your content, and use those actual characters in your code. The Mac has a Character Viewer that you can turn on in the Keyboard System Preference, and you can find and then drag and drop the characters you need, or use the matching Keyboard Viewer to see which keys to type. For example, trademark is Option+2. UTF-8 contains all of the characters and symbols from every written human language. So there is no excuse for using -- instead of an em dash. It is not a bad idea to learn the rules of punctuation and typography also ... for example, knowing that a period goes inside a close quote, not outside.

Using a tag for something like content-type and encoding is highly ironic, since without knowing those things, you couldn't parse the file to get the value of the meta tag.

No, that is not true. The browser starts out parsing the file as the browser's default encoding, either UTF-8 or ISO-8859-1. Since US-ASCII is a subset of both ISO-8859-1 and UTF-8, the browser can read just fine either way ... it is the same. When the browser encounters the meta charset tag, if the encoding is different than what the browser is already using, the browser reloads the page in the specified encoding. That is why we put the meta charset tag at the top, right after the head tag, before anything else, even the title. That way you can use UTF-8 characters in your title.

You must save your file(s) in UTF-8 encoding without BOM

That is not strictly true. If you only have US-ASCII characters in your document, you can Save it as US-ASCII and serve it as UTF-8, because it is a subset. But if there are Unicode characters, you are correct, you must Save as UTF-8 without BOM.

If you want a good text editor that will save your files in UTF-8, I recommend Notepad++.

On the Mac, use Bare Bones TextWrangler (free) from Mac App Store, or Bare Bones BBEdit which is at Mac App Store for $39.99 ... very cheap for such a great tool. In either app, there is a menu at the bottom of the document window where you specify the document encoding and you can easily choose "UTF-8 no BOM". And of course you can set that as the default for new documents in Preferences.

But if your Webserver serves the encoding in the HTTP header, which is recommended, both [meta tags] are needless.

That is incorrect. You should of course set the encoding in the HTTP header, but you should also set it in the meta charset attribute so that the page can be Saved by the user, out of the browser onto local storage and then Opened again later, in which case the only indication of the encoding that will be present is the meta charset attribute. You should also set a base tag for the same reason ... on the server, the base tag is unnecessary, but when opened from local storage, the base tag enables the page to work as if it is on the server, with all the assets in place and so on, no broken links.

AddDefaultCharset UTF-8

Or you can just change the encoding of particular file types like so:

AddType text/html;charset=utf-8 html

A tip for serving both UTF-8 and Latin-1 (ISO-8859-1) files is to give the UTF-8 files a "text" extension and Latin-1 files "txt."

AddType text/plain;charset=iso-8859-1 txt
AddType text/plain;charset=utf-8 text

Finally, consider Saving your documents with Unix line endings, not legacy DOS or (classic) Mac line endings, which don't help and may hurt, especially down the line as we get further and further from those legacy systems. An HTML document with valid HTML5, UTF-8 encoding, and Unix line endings is a job well done. You can share and edit and store and read and recover and rely on that document in many contexts. It's lingua franca. It's digital paper.

create another class and increase the with size with 2px example

.enquiry_fld_normal{
width:278px !important; 
}

.enquiry_fld_normal_select{
width:280px !important; 
 }

The easiest way is just a link tag:

<link rel="image_src" href="http://stackoverflow.com/images/logo.gif" />

But there are some other things you can add to your site to make it more Social media friendly:

Open Graph Tags

Open Graph tags are tags that you add to the <head> of your website to describe the entity your page represents, whether it is a band, restaurant, blog, or something else.

An Open Graph tag looks like this:

<meta property="og:tag name" content="tag value"/> 

If you use Open Graph tags, the following six are required:

• og:title - The title of the entity.
• og:type - The type of entity. You must select a type from the list of Open Graph types.
• og:image - The URL to an image that represents the entity. Images must be at least 50 pixels by 50 pixels. Square images work best, but you are allowed to use images up to three times as wide as they are tall.
• og:url - The canonical, permanent URL of the page representing the entity. When you use Open Graph tags, the Like button posts a link to the og:url instead of the URL in the Like button code.
• og:site_name - A human-readable name for your site, e.g., "IMDb".
• fb:admins or fb:app_id - A comma-separated list of either the Facebook IDs of page administrators or a Facebook Platform application ID. At a minimum, include only your own Facebook ID.

More information on Open Graph tags and details on Administering your page can be found on the Open Graph protocol documentation.

http://developers.facebook.com/docs/reference/plugins/like

I like this:

if (wlocation !== undefined)

But if you prefer the second way wouldn't be as you posted. It would be:

if (typeof wlocation  !== "undefined")

Try this sample SQL scripts for easy understanding,

CREATE TABLE TABLE1 (REFNO VARCHAR(10))
CREATE TABLE TABLE2 (REFNO VARCHAR(10))

--TRUNCATE TABLE TABLE1
--TRUNCATE TABLE TABLE2

INSERT INTO TABLE1 SELECT 'TEST_NAME'
INSERT INTO TABLE1 SELECT 'KUMAR'
INSERT INTO TABLE1 SELECT 'SIVA'
INSERT INTO TABLE1 SELECT 'SUSHANT'

INSERT INTO TABLE2 SELECT 'KUMAR'
INSERT INTO TABLE2 SELECT 'SIVA'
INSERT INTO TABLE2 SELECT 'SUSHANT'

SELECT * FROM TABLE1
SELECT * FROM TABLE2

DELETE T1 FROM TABLE1 T1 JOIN TABLE2 T2 ON T1.REFNO = T2.REFNO

Your case is:

   DELETE pgc
     FROM guide_category pgc 
LEFT JOIN guide g
       ON g.id_guide = gc.id_guide 
    WHERE g.id_guide IS NULL

Another easy way you can try this using analytic function as well:

SELECT * from 

(SELECT name, email,

COUNT(name) OVER (PARTITION BY name, email) cnt 

FROM users)

WHERE cnt >1;

If this is what you are looking for -

To find all the multiples between a given number and a limit

def find_multiples(integer, limit):
    return list(range(integer,limit+1, integer))

This should return -

Test.assert_equals(find_multiples(5, 25), [5, 10, 15, 20, 25])

Because you didn't specify the Header.

I've added an extended example:

var request = (HttpWebRequest)WebRequest.Create(strServer + strURL.Split('&')[1].ToString());

Header(ref request, p_Method);

And the method Header:

private void Header(ref HttpWebRequest p_request, string p_Method)
{
    p_request.ContentType = "application/x-www-form-urlencoded";
    p_request.Method = p_Method;
    p_request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows CE)";
    p_request.Host = strServer.Split('/')[2].ToString();
    p_request.Accept = "*/*";
    if (String.IsNullOrEmpty(strURLReferer))
    {
        p_request.Referer = strServer;
    }
    else
    {
        p_request.Referer = strURLReferer;
    }
    p_request.Headers.Add("Accept-Language", "en-us\r\n");
    p_request.Headers.Add("UA-CPU", "x86 \r\n");
    p_request.Headers.Add("Cache-Control", "no-cache\r\n");
    p_request.KeepAlive = true;
}

For those who want to substrat two timestamps (instead of dates), there is a similar solution:

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 1440 AS minutesInBetween
FROM ...

or

SELECT ( CAST( date2 AS DATE ) - CAST( date1 AS DATE ) ) * 86400 AS secondsInBetween
FROM ...

Assuming you really mean easiest and are not necessarily looking for a way to do this programmatically, you can do this:

1. Add, if not already there, a row of "column Musicians" to the spreadsheet. That is, if you have data in columns such as:

   Rory Gallagher      Guitar
   Gerry McAvoy        Bass
   Rod de'Ath          Drums
   Lou Martin          Keyboards
   Donkey Kong Sioux   Self-Appointed Semi-official Stomper
   

   Note: you might want to add "Musician" and "Instrument" in row 0 (you might have to insert a row there)

2. Save the file as a CSV file.

3. Copy the contents of the CSV file to the clipboard

4. Go to http://www.convertcsv.com/csv-to-json.htm

5. Verify that the "First row is column names" checkbox is checked

6. Paste the CSV data into the content area

7. Mash the "Convert CSV to JSON" button

   With the data shown above, you will now have:

   [
     {
       "MUSICIAN":"Rory Gallagher",
       "INSTRUMENT":"Guitar"
     },
     {
       "MUSICIAN":"Gerry McAvoy",
       "INSTRUMENT":"Bass"
     },
     {
       "MUSICIAN":"Rod D'Ath",
       "INSTRUMENT":"Drums"
     },
     {
       "MUSICIAN":"Lou Martin",
       "INSTRUMENT":"Keyboards"
     }
     {
       "MUSICIAN":"Donkey Kong Sioux",
       "INSTRUMENT":"Self-Appointed Semi-Official Stomper"
     }
   ]
   

   With this simple/minimalistic data, it's probably not required, but with large sets of data, it can save you time and headache in the proverbial long run by checking this data for aberrations and abnormalcy.

8. Go here: http://jsonlint.com/

9. Paste the JSON into the content area

10. Pres the "Validate" button.

If the JSON is good, you will see a "Valid JSON" remark in the Results section below; if not, it will tell you where the problem[s] lie so that you can fix it/them.

this can be achieved using below...

 List<String> unavailable = list1.stream()
                            .filter(e -> !list2.contains(e))
                            .collect(Collectors.toList());

class tweet_photos(models.Model):
upload_path='absolute path'
image=models.ImageField(upload_to=upload_path)
image_url = models.URLField(null=True, blank=True)
def save(self, *args, **kwargs):
    if self.image_url:
        import urllib, os
        from urlparse import urlparse
        file_save_dir = self.upload_path
        filename = urlparse(self.image_url).path.split('/')[-1]
        urllib.urlretrieve(self.image_url, os.path.join(file_save_dir, filename))
        self.image = os.path.join(file_save_dir, filename)
        self.image_url = ''
    super(tweet_photos, self).save()

Probably, the simplest solution on the ES6 age.

Adding following one liner directive makes HTML 'autofocus' attribute effective on Angular.js.

.directive('autofocus', ($timeout) => ({link: (_, e) => $timeout(() => e[0].focus())}))

Now, you can just use HTML5 autofocus syntax like:

<input type="text" autofocus>

The absolute divs are taken out of the flow of the document so the containing div does not have any content except for the padding. Give #box a height to fill it out.

#box {
    background-color: #000;
    position: relative;
    padding: 10px;
    width: 220px;
    height:30px;
}

Finally i found a way to clone specific commit using git cherry-pick. Assuming you don't have any repository in local and you are pulling specific commit from remote,

1) create empty repository in local and git init

2) git remote add origin "url-of-repository"

3) git fetch origin [this will not move your files to your local workspace unless you merge]

4) git cherry-pick "Enter-long-commit-hash-that-you-need"

Done.This way, you will only have the files from that specific commit in your local.

Enter-long-commit-hash:

You can get this using -> git log --pretty=oneline

Try this:
#ifdef _WIN64
// 64 bit code
#elif _WIN32
// 32 bit code
#else
   if(sizeof(void*)==4)

       // 32 bit code
   else 

       // 64 bit code   
#endif

Extending @Ryogi answer above, you can take advantage of the lower.tail parameter like so:

qt(0.25/2, 40, lower.tail = FALSE) # 75% confidence

qt(0.01/2, 40, lower.tail = FALSE) # 99% confidence

Creating dynamic objects with Newtonsoft.Json works really great.

//json is your string containing the JSON value
dynamic data = JsonConvert.DeserializeObject<dynamic>(json);

Now you can access the data object just like if it was a regular object. This is the JSON object we currently have as an example:

{ "ID":123,"Name":"Jack","Numbers":[1, 2, 3] }

This is how you access it after deserialization:

data.ID //Retrieve the int
data.Name //Retrieve the string
data.Numbers[0] //Retrieve the first element in the array

For C++, you could do:

export CXXFLAGS=-m32

This works with cmake.

I was using Spring-Boot, For me cut-paste of below in Pom.xml worked. May be file wasnt in sync.

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
</dependency>

Alternate Vanilla JS version with click outside to hide checkboxes:

let expanded = false;
const multiSelect = document.querySelector('.multiselect');

multiSelect.addEventListener('click', function(e) {
  const checkboxes = document.getElementById("checkboxes");
    if (!expanded) {
    checkboxes.style.display = "block";
    expanded = true;
  } else {
    checkboxes.style.display = "none";
    expanded = false;
  }
  e.stopPropagation();
}, true)

document.addEventListener('click', function(e){
  if (expanded) {
    checkboxes.style.display = "none";
    expanded = false;
  }
}, false)

I'm using addEventListener instead of onClick in order to take advantage of the capture/bubbling phase options along with stopPropagation(). You can read more about the capture/bubbling here: https://developer.mozilla.org/en-US/docs/Web/API/EventTarget/addEventListener

The rest of the code matches vitfo's original answer (but no need for onclick() in the html). A couple of people have requested this functionality sans jQuery.

Here's codepen example https://codepen.io/davidysoards/pen/QXYYYa?editors=1010

you can remove last comma:

var sentence = "I got,. commas, here,";
sentence = sentence.replace(/(.+),$/, '$1');
console.log(sentence);

<a href="<?php echo site_url('controller/function'); ?>Compose</a>

<a href="<?php echo site_url('controller/function'); ?>Inbox</a>

<a href="<?php echo site_url('controller/function'); ?>Outbox</a>

<a href="<?php echo site_url('controller/function'); ?>logout</a>

<a href="<?php echo site_url('controller/function'); ?>logout</a>

We can check by Four ways

The first way is

BOOL flagWayOne = TRUE; 
NSLog(@"The flagWayOne result is - %@",flagWayOne ? @"TRUE":@"FALSE");

The second way is

BOOL flagWayTwo = YES; 
NSLog(@"The flagWayTwo result is - %@",flagWayTwo ? @"YES":@"NO");

The third way is

BOOL flagWayThree = 1;
NSLog(@"The flagWayThree result is - %d",flagWayThree ? 1:0);

The fourth way is

BOOL flagWayFour = FALSE; // You can set YES or NO here.Because TRUE = YES,FALSE = NO and also 1 is equal to YES,TRUE and 0 is equal to FALSE,NO whatever you want set here.
NSLog(@"The flagWayFour result is - %s",flagWayFour ? YES:NO);

Python uses and and or conditionals.

i.e.

if foo == 'abc' and bar == 'bac' or zoo == '123':
  # do something

I think you can bring specific access to user and command with visudo something like this:

nobody ALL = NOPASSWD: /path/to/osascript myscript.scpt

and with php:

@exec("sudo /path/to/osascript myscript.scpt ");

supposing nobody user is running apache.

For windows just do this:

import os
os.system("color 01")
print('hello friends')

Where it says "01" that is saying background black, and text color blue. Go into CMD Prompt and type color help for a list of colors.

You might want Python's UUID functions:

21.15. uuid — UUID objects according to RFC 4122

eg:

import uuid
print uuid.uuid4()

7d529dd4-548b-4258-aa8e-23e34dc8d43d

So it turns out you can get around this by matching your module name to the file name. If you have the module name BankSpecialtyModule then the file name should be. bank-specialty.module.ts

As the thread mentioned in the comment, get-command in powershell can also work it out. For example, you can type get-command npm and the output is as below:

You can replace the image of an HTML IMG without needing to make any background image changes to the container div.

This is obtained using the CSS property box-sizing: border-box; (It gives you a possibility to put a kind of hover effect on an <IMG> very efficiently.)

To do this, apply a class like this to your image:

.image-replacement {
  display: block;
  -moz-box-sizing: border-box;
  box-sizing: border-box;
  background: url(http://akamaicovers.oreilly.com/images/9780596517748/cat.gif) no-repeat;/* this image will be shown over the image iSRC */
  width: 180px;
  height: 236px;
  padding-left: 180px;
}

Sample code: http://codepen.io/chriscoyier/pen/cJEjs

Original article: http://css-tricks.com/replace-the-image-in-an-img-with-css/

Hope this will help some of you guys who don't want to put a div to obtain an image having a "hover" effect.

Posting here the sample code:

HTML:

<img id="myImage" src="images/photo1.png" class="ClassBeforeImage-replacement">

jQuery:

$("#myImage").mouseover(function () {
    $(this).attr("class", "image-replacement");
});
$("#myImage").mouseout(function () {
    $(this).attr("class", "ClassBeforeImage-replacement");
});

I could use the following code. Thanks everyone.

int intID = 5;
DataTable Dt = MyFuctions.GetData();
Dt.PrimaryKey = new DataColumn[] { Dt.Columns["ID"] };
DataRow Drw = Dt.Rows.Find(intID);
if (Drw != null) Dt.Rows.Remove(Drw);

As suggested above the inclusion of

/usr/lib/openmpi/include 

in the include path takes care of this (in my case)

I don't know what you want to do, but this is how I actually translated your example code....

package test;

/**
 * @author The Elite Gentleman
 *
 */
public enum Strings {
    STRING_ONE("ONE"),
    STRING_TWO("TWO")
    ;

    private final String text;

    /**
     * @param text
     */
    Strings(final String text) {
        this.text = text;
    }

    /* (non-Javadoc)
     * @see java.lang.Enum#toString()
     */
    @Override
    public String toString() {
        return text;
    }
}

Alternatively, you can create a getter method for text.

You can now do Strings.STRING_ONE.toString();

I tried all the responses described here but my solution was changing inside my build.gradle file minSdkVersion from 8 to 9 because some libraries in my project can´t work with API 8, that´s was the reason for the message INSTALL_FAILED_OLDER_SDK:

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 22
        buildToolsVersion "22.0.1"

        defaultConfig {
            applicationId "com.tuna.hello.androidstudioapplication"
            minSdkVersion 9
            targetSdkVersion 22
            versionCode 1
            versionName "1.0"
        }
...
...
...

protected void gvTurnos_RowDataBound(object sender, GridViewRowEventArgs e)
{
    try
    {

        if (e.Row.RowType == DataControlRowType.EmptyDataRow)
        {
            LinkButton btn = (LinkButton)e.Row.FindControl("btnAgregarVacio");
            if (btn != null)
            {
                btn.Visible = rbFiltroEstatusCampus.SelectedValue == "1" ? true : false;
            }
        }
    }
    catch (Exception ex)
    {
        throw ex;
    }
}

You may use window.URL class:

new URL(location.href).searchParams.get('year')
// Returns 2008 for href = "http://localhost/search.php?year=2008".
// Or in two steps:
const params = new URL(location.href).searchParams;
const year = params.get('year');

Is your server single-threaded? If so, what polling / multiplexing function are you using?

Using select() does not work beyond the hard-coded maximum file descriptor limit set at compile-time, which is hopeless (normally 256, or a few more).

poll() is better but you will end up with the scalability problem with a large number of FDs repopulating the set each time around the loop.

epoll() should work well up to some other limit which you hit.

10k connections should be easy enough to achieve. Use a recent(ish) 2.6 kernel.

How many client machines did you use? Are you sure you didn't hit a client-side limit?

This error means that, while linking, compiler is not able to find the definition of main() function anywhere.

In your makefile, the main rule will expand to something like this.

main: producer.o consumer.o AddRemove.o
   gcc -pthread -Wall -o producer.o consumer.o AddRemove.o

As per the gcc manual page, the use of -o switch is as below

-o file     Place output in file file. This applies regardless to whatever sort of output is being produced, whether it be an executable file, an object file, an assembler file or preprocessed C code. If -o is not specified, the default is to put an executable file in a.out.

It means, gcc will put the output in the filename provided immediate next to -o switch. So, here instead of linking all the .o files together and creating the binary [main, in your case], its creating the binary as producer.o, linking the other .o files. Please correct that.

print("Hello, World!")

You are probably using Python 3.0, where print is now a function (hence the parenthesis) instead of a statement.

You can try : go to edit>preferencec>type.. select type > choose text engine options select east asian. Restart photoshop. Create new peroject. Try text tool again.

(if you want to use your project created with other text engine type) copy /paste all layers to new project.

1. Go to Server tab

2. Click on No servers are available. Click this link to create a new server.

3. Select Tomcat V8.0 from server type list:

4. Provide path of server:

5. Click Finish.

6. You will see server added:

7. Right click->Start

Now you can run your web applications on server.

This shows the number of connections per each DB:

SELECT 
    DB_NAME(dbid) as DBName, 
    COUNT(dbid) as NumberOfConnections,
    loginame as LoginName
FROM
    sys.sysprocesses
WHERE 
    dbid > 0
GROUP BY 
    dbid, loginame

And this gives the total:

SELECT 
    COUNT(dbid) as TotalConnections
FROM
    sys.sysprocesses
WHERE 
    dbid > 0

If you need more detail, run:

sp_who2 'Active'

Note: The SQL Server account used needs the 'sysadmin' role (otherwise it will just show a single row and a count of 1 as the result)

Great question @aryaxt -- you can tell it was a great question because you asked it 5 years ago and I stumbled upon it today trying to find the answer!

I just tried to edit the accepted answer to include this, but in case my edit does not make it in:

If your table was not that large, and assuming your primary key was an auto-incrementing integer you could do something like this:

SELECT 
  table.*
FROM table
--be able to take out dupes later
LEFT JOIN (
  SELECT field, MAX(id) as id
  FROM table
  GROUP BY field
) as noDupes on noDupes.id = table.id
WHERE
  //this will result in only the last instance being seen
  noDupes.id is not NULL

Java 8+

Encode or decode byte arrays:

byte[] encoded = Base64.getEncoder().encode("Hello".getBytes());
println(new String(encoded));   // Outputs "SGVsbG8="

byte[] decoded = Base64.getDecoder().decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64.getEncoder().encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(Base64.getDecoder().decode(encoded.getBytes()));
println(decoded)    // Outputs "Hello"

For more info, see Base64.

Java < 8

Base64 is not bundled with Java versions less than 8. I recommend using Apache Commons Codec.

For direct byte arrays:

Base64 codec = new Base64();
byte[] encoded = codec.encode("Hello".getBytes());
println(new String(encoded));   // Outputs "SGVsbG8="

byte[] decoded = codec.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

Base64 codec = new Base64();
String encoded = codec.encodeBase64String("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(codec.decodeBase64(encoded));
println(decoded)    // Outputs "Hello"

Spring

If you're working in a Spring project already, you may find their org.springframework.util.Base64Utils class more ergonomic:

For direct byte arrays:

byte[] encoded = Base64Utils.encode("Hello".getBytes());
println(new String(encoded))    // Outputs "SGVsbG8="

byte[] decoded = Base64Utils.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64Utils.encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = Base64Utils.decodeFromString(encoded);
println(new String(decoded))    // Outputs "Hello"

Android (with Java < 8)

If you are using the Android SDK before Java 8 then your best option is to use the bundled android.util.Base64.

For direct byte arrays:

byte[] encoded = Base64.encode("Hello".getBytes());
println(new String(encoded))    // Outputs "SGVsbG8="

byte [] decoded = Base64.decode(encoded);
println(new String(decoded))    // Outputs "Hello"

Or if you just want the strings:

String encoded = Base64.encodeToString("Hello".getBytes());
println(encoded);   // Outputs "SGVsbG8="

String decoded = new String(Base64.decode(encoded));
println(decoded)    // Outputs "Hello"

try this

 <script type="text/javascript">
        $(document).ready(function () {
            $("#chkdwn2").click(function () {
                if (this.checked)
                    $('#dropdown').attr('disabled', 'disabled');
                else
                    $('#dropdown').removeAttr('disabled');
            });
        });
    </script>

None of the solutions here worked for me. JSON.stringify seems to be what a lot of people say, but it cuts out functions and seems pretty broken for some objects and arrays I tried when testing it.

I made my own solution which works in Chrome at least. Posting it here so anyone that looks this up on Google can find it.

//Make an object a string that evaluates to an equivalent object
//  Note that eval() seems tricky and sometimes you have to do
//  something like eval("a = " + yourString), then use the value
//  of a.
//
//  Also this leaves extra commas after everything, but JavaScript
//  ignores them.
function convertToText(obj) {
    //create an array that will later be joined into a string.
    var string = [];

    //is object
    //    Both arrays and objects seem to return "object"
    //    when typeof(obj) is applied to them. So instead
    //    I am checking to see if they have the property
    //    join, which normal objects don't have but
    //    arrays do.
    if (typeof(obj) == "object" && (obj.join == undefined)) {
        string.push("{");
        for (prop in obj) {
            string.push(prop, ": ", convertToText(obj[prop]), ",");
        };
        string.push("}");

    //is array
    } else if (typeof(obj) == "object" && !(obj.join == undefined)) {
        string.push("[")
        for(prop in obj) {
            string.push(convertToText(obj[prop]), ",");
        }
        string.push("]")

    //is function
    } else if (typeof(obj) == "function") {
        string.push(obj.toString())

    //all other values can be done with JSON.stringify
    } else {
        string.push(JSON.stringify(obj))
    }

    return string.join("")
}

EDIT: I know this code can be improved but just never got around to doing it. User andrey suggested an improvement here with the comment:

Here is a little bit changed code, which can handle 'null' and 'undefined', and also do not add excessive commas.

Use that at your own risk as I haven't verified it at all. Feel free to suggest any additional improvements as a comment.

'wc' counts lines, words, chars, so to count all lines (including blank ones) use:

wc *.py

To filter out the blank lines, you can use grep:

grep -v '^\s*$' *.py | wc

'-v' tells grep to output all lines except those that match '^' is the start of a line '\s*' is zero or more whitespace characters '$' is the end of a line *.py is my example for all the files you wish to count (all python files in current dir) pipe output to wc. Off you go.

I'm answering my own (genuine) question. Couldn't find an stackoverflow entry that covered this.

Thanks to Andrey Egorov, in my case with python setAttribute not working, but I found I can set the property directly,

Try this code:

driver.execute_script("document.getElementById('q').value='value here'")

import java.io.IOException;
import java.lang.ProcessBuilder;

public class handlingexe {
    public static void main(String[] args) throws IOException {
        ProcessBuilder p = new ProcessBuilder();
        System.out.println("Started EXE");
        p.command("C:\\Users\\AppData\\Local\\Google\\Chrome\\Application\\chrome.exe");   

        p.start();
        System.out.println("Started EXE"); 
    }
}

This is how you can add a textField text change listener using Swift 3:

Declare your class as UITextFieldDelegate

override func viewDidLoad() {
    super.viewDidLoad()

    textField.delegate = self

    textField.addTarget(self, action: #selector(UITextFieldDelegate.textFieldShouldEndEditing(_:)), for: UIControlEvents.editingChanged)
}

Then just traditionally add a textFieldShouldEndEditing function:

func textFieldShouldEndEditing(_ textField: UITextField) -> Bool { // do stuff
        return true 
}

How did you configure networking when you created the guest? The easiest way is to set the network adapter to NAT, if you don't need to access the vm from another pc.

Perhaps use this:

[a[i] for i in (1,2,5)]
# [11, 12, 15]

Tables work differently; sometimes counter-intuitively.

The solution is to use width on the table cells instead of max-width.

Although it may sound like in that case the cells won't shrink below the given width, they will actually.
with no restrictions on c, if you give the table a width of 70px, the widths of a, b and c will come out as 16, 42 and 12 pixels, respectively.
With a table width of 400 pixels, they behave like you say you expect in your grid above.
Only when you try to give the table too small a size (smaller than a.min+b.min+the content of C) will it fail: then the table itself will be wider than specified.

I made a snippet based on your fiddle, in which I removed all the borders and paddings and border-spacing, so you can measure the widths more accurately.

  width: 70px;_x000D_

I thought I had misunderstood but I was right. In this scenario, it will be ActiveWorkbook.Path

But the main issue was not here. The problem was with these 2 lines of code

strFile = Dir(strPath & "*.csv")

Which should have written as

strFile = Dir(strPath & "\*.csv")

and

With .QueryTables.Add(Connection:="TEXT;" & strPath & strFile, _

Which should have written as

With .QueryTables.Add(Connection:="TEXT;" & strPath & "\" & strFile, _

Fixed positioning is supposed to define everything in relation to the viewport, so position:fixed is always going to do that. Try using position:relative on the child div instead. (I realize you might need the fixed positioning for other reasons, but if so - you can't really make the width match it's parent with out JS without inherit)

This would be easy to understand:

#include <iostream>

}

I understand that you want the Widget2 sharing the bottom border with the contents div. Try adding

style="position: relative; bottom: 0px"

to your Widget2 tag. Also try:

style="position: absolute; bottom: 0px"

if you want to snap your widget to the bottom of the screen.

I am a little rusty with CSS, perhaps the correct style is "margin-bottom: 0px" instead "bottom: 0px", give it a try. Also the pull-right class seems to add a "float=right" style to the element, and I am not sure how this behaves with "position: relative" and "position: absolute", I would remove it.

Try providing username and password in your client like below

client.ClientCredentials.UserName.UserName = @"Domain\username"; client.ClientCredentials.UserName.Password = "password";

I was able to achieve this by using set -x in the main script (which makes the script print out every command that is executed) and writing a wrapper script which just shows the last line of output generated by set -x.

This is the main script:

#!/bin/bash
set -x
echo some command here
echo last command

And this is the wrapper script:

#!/bin/sh
./test.sh 2>&1 | grep '^\+' | tail -n 1 | sed -e 's/^\+ //'

Running the wrapper script produces this as output:

echo last command

See this fiddle for a preview and check the documentation for jquerys toggle and animate methods.

$('#toggle').toggle(function(){
    $('#A').animate({width:0});
    $('#B').animate({left:0});
},function(){
    $('#A').animate({width:200});
    $('#B').animate({left:200});
});

Basically you animate on the properties that sets the layout.

A more advanced version:

$('#toggle').toggle(function(){
    $('#A').stop(true).animate({width:0});
    $('#B').stop(true).animate({left:0});
},function(){
    $('#A').stop(true).animate({width:200});
    $('#B').stop(true).animate({left:200});
})

This stops the previous animation, clears animation queue and begins the new animation.

Make sure your declare the tolayer5 function as a prototype, or define the full function definition, earlier in the file where you use it.

The solutions is to use:

delete require.cache[require.resolve(<path of your script>)]

_{Find here some basic explanations for those who, like me, are a bit new in this:}

Suppose you have a dummy example.js file in the root of your directory:

exports.message = "hi";
exports.say = function () {
  console.log(message);
}

Then you require() like this:

$ node
> require('./example.js')
{ message: 'hi', say: [Function] }

If you then add a line like this to example.js:

exports.message = "hi";
exports.say = function () {
  console.log(message);
}

exports.farewell = "bye!";      // this line is added later on

And continue in the console, the module is not updated:

> require('./example.js')
{ message: 'hi', say: [Function] }

That's when you can use delete require.cache[require.resolve()] indicated in luff's answer:

> delete require.cache[require.resolve('./example.js')]
true
> require('./example.js')
{ message: 'hi', say: [Function], farewell: 'bye!' }

So the cache is cleaned and the require() captures the content of the file again, loading all the current values.

I think the more stable solution is to use screen instead of window, because it could be both - landscape or portrait if you will resize your browser window on desktop computer.

if (screen.height > screen.width){
    alert("Please use Landscape!");
}

    let cancelBarButton = UIBarButtonItem(title: "Cancel", style: .done, target: self, action: #selector(cancelPressed(_:)))
    cancelBarButton.setTitleTextAttributes( [NSFontAttributeName : UIFont.cancelBarButtonFont(),
                                                          NSForegroundColorAttributeName : UIColor.white], for: .normal)
    self.navigationItem.leftBarButtonItem = cancelBarButton


    func cancelPressed(_ sender: UIBarButtonItem ) {
        self.dismiss(animated: true, completion: nil)
    }

I don't think there's any one module that you can easily download to implement scp, however you might find this helpful: http://www.ibm.com/developerworks/linux/library/l-twist4.html

With Groovy on the path:

groovy -e " println Integer.MAX_VALUE "

(Groovy is extremely useful for quick reference, within a Java context.)

I think you have to write your own filter for that. It's actually the example for custom filters in the documentation: http://jinja.pocoo.org/docs/api/#custom-filters

Generating random password for user

first need to define users variable then follow below

tasks:

- name: Generate Passwords
  become: no
  local_action: command pwgen -N 1 8
  with_items: '{{ users }}'
  register: user_passwords

- name: Update User Passwords
  user:
    name: '{{ item.item }}'
    password: "{{ item.stdout | password_hash('sha512')}}"
    update_password: on_create
  with_items: '{{ user_passwords.results }}'

- name: Save Passwords Locally
  become: no
  local_action: copy content={{ item.stdout }} dest=./{{ item.item }}.txt
  with_items: '{{ user_passwords.results }}'

You could try:

alist[:] = []

Which means: Splice in the list [] (0 elements) at the location [:] (all indexes from start to finish)

The [:] is the slice operator. See this question for more information.

POD is the official way to do multi line comments in Perl,

• see Multi-line comments in perl code and
• Better ways to make multi-line comments in Perl for more detail.

From faq.perl.org[perlfaq7]

• How can I comment out a large block of Perl code?

The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with =cut, ending the Pod section:

=pod

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=cut

The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.

The =begin directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments with comment. End the comment using =end with the same label. You still need the =cut to go back to Perl code from the Pod comment:

=begin comment

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=end comment

=cut
