In this case, adding display:flex to the 2 parent <div> tags was the answer

• How do I invoke a maven task without leaving vi?

  Maven is no different than any other shell command:

  :!mvn

  You can :set makeprg=mvn if you already have a favourite key mapping for :make.

• Can I get code completion?

  Yes, eclim is great, a bridge between vim's editing efficiency and Eclipse's Java language-specific awareness.

  <C-n> and <C-p> are not-so-great, but amazingly helpful.

• How's the syntax highlighting?

  More than good enough for a regex-based highligher.

You may want to consider tools for other vim+java purposes, like code templates (snippetEmu—default snippets suck, but customizability shines), searching for usages and going to declarations (eclim, grep, ctags), generating getters and setters (java_getset, or eclim), automatic imports (eclim). You might also need a java shell for quick experiments (the BeanShell, a.k.a. bsh).

#Script for calculating various values in MB
echo "Please enter some input: "
read input_variable
echo $input_variable | awk '{ foo = $1 / 1024 / 1024 ; print foo "MB" }'

There are two flavors of table valued functions. One that is just a select statement and one that can have more rows than just a select statement.

This can not have a variable:

create function Func() returns table
as
return
select 10 as ColName

You have to do like this instead:

create function Func()
returns @T table(ColName int)
as
begin
  declare @Var int
  set @Var = 10
  insert into @T(ColName) values (@Var)
  return
end

Writing as

var formData = new FormData;
var array = ['1', '2'];
for (var i = 0; i < array.length; i++) {
    formData.append('array_php_side[]', array[i]);
}

you can receive just as normal array post/get by php.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

A regular expressoin would be the easiest way. If you write the regex the correct way, you wont need multiple calls.

Change it to this:

string s = System.Text.RegularExpressions.Regex.Replace(s, @"\s{2,}", " "); 

I needed to change environment variable PATH and PHPRC. Also open new cmd.

I already had PHP installed and added EasyPHP when the problem came up. After I changed both variables to C:\Program Files (x86)\EasyPHP-DevServer-14.1VC9\binaries\php\php_runningversion it worked fine.

Yes that is correct. "Boolean variables only have two possible values: true (1) and false (0)." cpp tutorial on boolean values

To delete multiple branches based on a specified pattern do the following:

Open the terminal, or equivalent and type in following commands:

git branch | grep "<pattern>" (preview of the branches based on pattern)

git branch | grep "<pattern>" | xargs git branch -D (replace the <pattern> with a regular expression to match your branch names)

Remove all 3.2.x branches, you need to type

git branch | grep "3.2" | xargs git branch -D

That's all!

You are good to go!

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

try this: objectId.str;

see doc.

UPDATE: Another writeup here: How to add publisher in Installshield 2018 (might be better).

I am not too well informed about this issue, but please see if this answer to another question tells you anything useful (and let us know so I can evolve a better answer here): How to pass the Windows Defender SmartScreen Protection? That question relates to BitRock - a non-MSI installer technology, but the overall issue seems to be the same.

Extract from one of the links pointed to in my answer above: "...a certificate just isn't enough anymore to gain trust... SmartScreen is reputation based, not unlike the way StackOverflow works... SmartScreen trusts installers that don't cause problems. Windows machines send telemetry back to Redmond about installed programs and how much trouble they cause. If you get enough thumbs-up then SmartScreen stops blocking your installer automatically. This takes time and lots of installs to get sufficient thumbs. There is no way to find out how far along you got."

Honestly this is all news to me at this point, so do get back to us with any information you dig up yourself.

The actual dialog text you have marked above definitely relates to the Zone.Identifier alternate data stream with a value of 3 that is added to any file that is downloaded from the Internet (see linked answer above for more details).

I was not able to mark this question as a duplicate of the previous one, since it doesn't have an accepted answer. Let's leave both question open for now? (one question is for MSI, one is for non-MSI).

Supplement to Mario Knezovic 's answer:

class IA
{
public:
  virtual int getNum() const = 0;
};

class BaseA : public IA
{
public:
 inline virtual int getNum() const final {return ...};
};

class ImplA : public BaseA {...};

IA* pa = ...;
...
ImplA* impla = static_cast<ImplA*>(pa);

//the following line should cause compiler to use the inlined function BaseA::getNum(), 
//instead of dynamic binding (via vtable or something).
//any class/subclass of BaseA will benefit from it

int n = impla->getNum();

The above code shows the theory, but not actually tested on real compilers. Much appreciated if anyone paste a disassembled output.

One solution is to run manually a shell function that sets my environment to work or personal, but I am pretty sure that I will often forget to switch to the correct identity resulting in committing under the wrong identity.

That was exactly my problem. I have written a hook script which warns you if you have any github remote and not defined a local username.

Here's how you set it up:

1. Create a directory to hold the global hook

   mkdir -p ~/.git-templates/hooks

2. Tell git to copy everything in ~/.git-templates to your per-project .git directory when you run git init or clone

   git config --global init.templatedir '~/.git-templates'

3. And now copy the following lines to ~/.git-templates/hooks/pre-commit and make the file executable (don't forget this otherwise git won't execute it!)

#!/bin/bash

RED='\033[0;31m' # red color
NC='\033[0m' # no color

GITHUB_REMOTE=$(git remote -v | grep github.com)
LOCAL_USERNAME=$(git config --local user.name)

if [ -n "$GITHUB_REMOTE" ] && [ -z "$LOCAL_USERNAME" ]; then
    printf "\n${RED}ATTENTION: At least one Github remote repository is configured, but no local username. "
    printf "Please define a local username that matches your Github account.${NC} [pre-commit hook]\n\n"
    exit 1
fi

If you use other hosts for your private repositories you have to replace github.com according to your needs.

Now every time you do a git init or git clone git will copy this script to the repository and executes it before any commit is done. If you have not set a local username it will output a warning and won't let you commit.

You can compress the bitmap as an byte's array and then uncompress it in another activity, like this.

Compress!!

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] bytes = stream.toByteArray(); 
        setresult.putExtra("BMP",bytes);

Uncompress!!

        byte[] bytes = data.getByteArrayExtra("BMP");
        Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);

Use the driver to send keys like the pagedown or downarrow key to bring the element into view. I know it's too simple a solution and might not be applicable in all cases.

You can just place this line in a JavaScript function:

__doPostBack('btnSubmit','OnClick');

Or do something like this:

$('#btnSubmit').trigger('click');

As of PostgreSQL 9.3, you can use the command pg_isready to determine the connection status of a PostgreSQL server.

From the docs:

pg_isready returns 0 to the shell if the server is accepting connections normally, 1 if the server is rejecting connections (for example during startup), 2 if there was no response to the connection attempt, and 3 if no attempt was made (for example due to invalid parameters).

You can just ask for cancellation but not really terminate it. See this answer.

I use the xcopy command with the /L option to get the file names. So if you want to get either a directory or all the files in the subdirectory you could do something like this:

for /f "delims=" %%a IN ('xcopy "D:\*.pdf" c:\ /l') do echo %%a

I just use the c:\ as the destination because it always exists on windows systems and it is not copying so it does not matter. if you want the subdirectories too just use /s option on the end. You can also use the other switches of xcopy if you need them for other reasons.

@Mahender, you probably meant the difference between \W (instead of \w) and \b. If not, then I would agree with @BoltClock and @jwismar above. Otherwise continue reading.

\W would match any non-word character and so its easy to try to use it to match word boundaries. The problem is that it will not match the start or end of a line. \b is more suited for matching word boundaries as it will also match the start or end of a line. Roughly speaking (more experienced users can correct me here) \b can be thought of as (\W|^|$). [Edit: as @?mega mentions below, \b is a zero-length match so (\W|^|$) is not strictly correct, but hopefully helps explain the diff]

Quick example: For the string Hello World, .+\W would match Hello_ (with the space) but will not match World. .+\b would match both Hello and World.

    Uri addContactsUri = ContactsContract.Data.CONTENT_URI;

    } else if ("mobile".equalsIgnoreCase(phoneTypeStr)) {
        phoneContactType = ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE;
    } else if ("work".equalsIgnoreCase(phoneTypeStr)) {
        phoneContactType = ContactsContract.CommonDataKinds.Phone.TYPE_WORK;
    }
    // Put phone type value.
    contentValues.put(ContactsContract.CommonDataKinds.Phone.TYPE, phoneContactType);

    // Insert new contact data into phone contact list.
    activity.getContentResolver().insert(addContactsUri, contentValues);

}

int arsize(int st1[]) {
    int i = 0;
    for (i; !(st1[i] & (1 << 30)); i++);
    return i;
}

This works for me :)

From Oracle documentation page on ScheduledThreadPoolExecutor

A ThreadPoolExecutor that can additionally schedule commands to run after a given delay, or to execute periodically. This class is preferable to Timer when multiple worker threads are needed, or when the additional flexibility or capabilities of ThreadPoolExecutor (which this class extends) are required.

ExecutorService/ThreadPoolExecutor or ScheduledThreadPoolExecutor is obvious choice when you have multiple worker threads.

Pros of ExecutorService over Timer

1. Timer can't take advantage of available CPU cores unlike ExecutorService especially with multiple tasks using flavours of ExecutorService like ForkJoinPool
2. ExecutorService provides collaborative API if you need coordination between multiple tasks. Assume that you have to submit N number of worker tasks and wait for completion of all of them. You can easily achieve it with invokeAll API. If you want to achieve the same with multiple Timer tasks, it would be not simple.

3. ThreadPoolExecutor provides better API for management of Thread life cycle.

   Thread pools address two different problems: they usually provide improved performance when executing large numbers of asynchronous tasks, due to reduced per-task invocation overhead, and they provide a means of bounding and managing the resources, including threads, consumed when executing a collection of tasks. Each ThreadPoolExecutor also maintains some basic statistics, such as the number of completed tasks

   Few advantages:

   a. You can create/manage/control life cycle of Threads & optimize thread creation cost overheads

   b. You can control processing of tasks ( Work Stealing, ForkJoinPool, invokeAll) etc.

   c. You can monitor the progress and health of threads

   d. Provides better exception handling mechanism

Sorry for late reply but still felt like posting my answer if it helps.It works for 6 digits OTP.

    @Override
    public void onOTPReceived(String messageBody)
    {
        Pattern pattern = Pattern.compile(SMSReceiver.OTP_REGEX);
        Matcher matcher = pattern.matcher(messageBody);
        String otp = HkpConstants.EMPTY;
        while (matcher.find())
        {
            otp = matcher.group();
        }
        checkAndSetOTP(otp);
    }
Adding constants here

public static final String OTP_REGEX = "[0-9]{1,6}";

For SMS listener one can follow the below class

public class SMSReceiver extends BroadcastReceiver
{
    public static final String SMS_BUNDLE = "pdus";
    public static final String OTP_REGEX = "[0-9]{1,6}";
    private static final String FORMAT = "format";

    private OnOTPSMSReceivedListener otpSMSListener;

    public SMSReceiver(OnOTPSMSReceivedListener listener)
    {
        otpSMSListener = listener;
    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle intentExtras = intent.getExtras();
        if (intentExtras != null)
        {
            Object[] sms_bundle = (Object[]) intentExtras.get(SMS_BUNDLE);
            String format = intent.getStringExtra(FORMAT);
            if (sms_bundle != null)
            {
                otpSMSListener.onOTPSMSReceived(format, sms_bundle);
            }
            else {
                // do nothing
            }
        }
    }

    @FunctionalInterface
    public interface OnOTPSMSReceivedListener
    {
        void onOTPSMSReceived(@Nullable String format, Object... smsBundle);
    }
}

    @Override
    public void onOTPSMSReceived(@Nullable String format, Object... smsBundle)
    {
        for (Object aSmsBundle : smsBundle)
        {
            SmsMessage smsMessage = getIncomingMessage(format, aSmsBundle);
            String sender = smsMessage.getDisplayOriginatingAddress();
            if (sender.toLowerCase().contains(ONEMG))
            {
                getIncomingMessage(smsMessage.getMessageBody());
            } else
            {
                // do nothing
            }
        }
    }

    private SmsMessage getIncomingMessage(@Nullable String format, Object aObject)
    {
        SmsMessage currentSMS;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && format != null)
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);
        } else
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject);
        }

        return currentSMS;
    }

Use the following function

window.scrollTo(xpos, ypos)

Here xpos is Required. The coordinate to scroll to, along the x-axis (horizontal), in pixels

ypos is also Required. The coordinate to scroll to, along the y-axis (vertical), in pixels

I'm not a java expert but I solve your problem like this:

@FunctionalInterface
public interface AutoCompleteCallable<T> {
  String call(T model) throws Exception;
}

I define the parameter in my special Interface

public <T> void initialize(List<T> entries, AutoCompleteCallable getSearchText) {.......
//call here
String value = getSearchText.call(item);
...
}

Finally, I implement getSearchText method while calling initialize method.

initialize(getMessageContactModelList(), new AutoCompleteCallable() {
          @Override
          public String call(Object model) throws Exception {
            return "custom string" + ((xxxModel)model.getTitle());
          }
        })

Old Question but maybe it helps someone.

I had the problem that my player was able to squeeze through openings smaller than the players collider and that solved it. It also helps with stopping fast moving objects.

That's an odd approach with isUserAnswer. Are you really going to send all three choices back to the server where it will loop through each one checking for isUserAnswer == true? If so, you can try this:

http://jsfiddle.net/hgxjv/4/

HTML:

<input type="radio" name="response" value="true" ng-click="setChoiceForQuestion(question1, choice)"/>

JavaScript:

$scope.setChoiceForQuestion = function (q, c) {
    angular.forEach(q.choices, function (c) {
        c.isUserAnswer = false;
    });

    c.isUserAnswer = true;
};

Alternatively, I'd recommend changing your tack:

http://jsfiddle.net/hgxjv/5/

<input type="radio" name="response" value="{{choice.id}}" ng-model="question1.userChoiceId"/>

That way you can just send {{question1.userChoiceId}} back to the server.

Simple stuff:

Using print_r, var_dump or var_export should do it pretty nicely if you look at the result in view-source mode not in HTML mode or as @Joel Larson said if you wrap everything in a <pre> tag.

print_r is best for readability but it doesn't print null/false values.

var_dump is best for checking types of values and lengths and null/false values.

var_export is simmilar to var_dump but it can be used to get the dumped string.

The format returned by any of these is indented correctly in the source code and var_export can be used for logging since it can be used to return the dumped string.

Advanced stuff:

Use the xdebug plug-in for PHP this prints var_dumps as HTML formatted strings not as raw dump format and also allows you to supply a custom function you want to use for formatting.

Assuming your driver is in path,

String url = "jdbc:mysql://localhost/test";
Class.forName ("com.mysql.jdbc.Driver").newInstance ();
Connection conn = DriverManager.getConnection (url, "username", "password");

Yeah, I had the same question for a long time and I found the perfect one. Here are some parameters from it.

https://maps.google.com/?parameter=value

q=

Used to specify the search query in Google maps search.
eg :

https://maps.google.com/?q=newyork or
https://maps.google.com/?q=51.03841,-114.01679

near=

Used to specify the location instead of putting it into q. Also has the added effect of allowing you to increase the AddressDetails Accuracy value by being more precise. Mostly only useful if q is a business or suchlike.

z=

Zoom level. Can be set 19 normally, but in certain cases can go up to 23.

ll=

Latitude and longitude of the map centre point. Must be in that order. Requires decimal format. Interestingly, you can use this without q, in which case it doesn’t show a marker.

sll=

Similar to ll, only this sets the lat/long of the centre point for a business search. Requires the same input criteria as ll.

t=

Sets the kind of map shown. Can be set to:

m – normal  map
k – satellite
h – hybrid
p – terrain

saddr=

Sets the starting point for directions searches. You can also add text into this in brackets to bold it in the directions sidebar.

daddr=

Sets the end point for directions searches, and again will bold any text added in brackets.You can also add "+to:" which will set via points. These can be added multiple times.

via=

Allows you to insert via points in directions. Must be in CSV format. For example, via=1,5 addresses 1 and 5 will be via points without entries in the sidebar. The start point (which is set as 0), and 2, 3 and 4 will all show full addresses.

doflg=

Changes the units used to measure distance (will default to the standard unit in country of origin). Change to ptk for metric or ptm for imperial.

msa=

Does stuff with My Maps. Set to 0 show defined My Maps, b to turn the My Maps sidebar on, 1 to show the My Maps tab on its own, or 2 to go to the new My Map creator form.

reference : http://moz.com/ugc/everything-you-never-wanted-to-know-about-google-maps-parameters

The properties that can be set for a figure is referenced here.

You could then use:

figure_number = 1;
x      = 0;   % Screen position
y      = 0;   % Screen position
width  = 600; % Width of figure
height = 400; % Height of figure (by default in pixels)

figure(figure_number, 'Position', [x y width height]);

An example might be helpful. Imagine a system which generates data and puts it into a data store, either a file on disk or a database.

High Cohesion can be achieved by separate the data store code from the data production code. (and in fact separating the disk storage from the database storage).

Low Coupling can be achieved by making sure that the data production doesn't have any unnecessary knowledge of the data store (e.g. doesn't ask the data store about filenames or db connections).

This is my way to do it!

public static byte[] concatByteArrays(byte[]... inputs) {
    int i = inputs.length - 1, len = 0;
    for (; i >= 0; i--) {
        len += inputs[i].length;
    }
    byte[] r = new byte[len];
    for (i = inputs.length - 1; i >= 0; i--) {
        System.arraycopy(inputs[i], 0, r, len -= inputs[i].length, inputs[i].length);
    }
    return r;
}

Features:

• Use varargs (...) to be called with any number of byte[].
• Use System.arraycopy() that is implemented with machine specific native code, to ensure high speed operation.
• Create a new byte[] with the exact size that is need it.
• Allocate little less int variables by reusing the i and len variables.
• Faster comparison with constants.

Keep in mind:

The better way to do this, is by copy the @Jonathan code. The issue comes from the native variable arrays, because Java create new variables when this data type is passed to another function.

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:

supposing nobody user is running apache.

In addition to @senderle's here, some might also be wondering how to use the functionality of multiprocessing.Pool.

The nice thing is that there is a .Pool() method to the manager instance that mimics all the familiar API of the top-level multiprocessing.

from itertools import repeat
import multiprocessing as mp
import os
import pprint

def f(d: dict) -> None:
    pid = os.getpid()
    d[pid] = "Hi, I was written by process %d" % pid

if __name__ == '__main__':
    with mp.Manager() as manager:
        d = manager.dict()
        with manager.Pool() as pool:
            pool.map(f, repeat(d, 10))
        # `d` is a DictProxy object that can be converted to dict
        pprint.pprint(dict(d))

Output:

$ python3 mul.py 
{22562: 'Hi, I was written by process 22562',
 22563: 'Hi, I was written by process 22563',
 22564: 'Hi, I was written by process 22564',
 22565: 'Hi, I was written by process 22565',
 22566: 'Hi, I was written by process 22566',
 22567: 'Hi, I was written by process 22567',
 22568: 'Hi, I was written by process 22568',
 22569: 'Hi, I was written by process 22569',
 22570: 'Hi, I was written by process 22570',
 22571: 'Hi, I was written by process 22571'}

This is a slightly different example where each process just logs its process ID to the global DictProxy object d.

I recently came to a similar situation where I needed to register a handler for an event only once. I found that you can safely unregister first, and then register again, even if the handler is not registered at all:

myClass.MyEvent -= MyHandler;
myClass.MyEvent += MyHandler;

Note that doing this every time you register your handler will ensure that your handler is registered only once. Sounds like a pretty good practice to me :)

Thanks , but i found an alternative solution using ffmpeg:

def save():
    os.system("ffmpeg -r 1 -i img%01d.png -vcodec mpeg4 -y movie.mp4")

But thank you for your help :)

Symbolic or soft link (files or directories, more flexible and self documenting)

#     Source                             Link
ln -s /home/jake/doc/test/2000/something /home/jake/xxx

Hard link (files only, less flexible and not self documenting)

#   Source                             Link
ln /home/jake/doc/test/2000/something /home/jake/xxx

More information: man ln

/home/jake/xxx is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:

1. cd /home/jake/
2. ln -s /home/jake/doc/test/2000/something xxx

I've tested in my own shell script.

• $new_username means newly created user
• $new_password means newly password

For CentOS

echo "$new_password" | passwd --stdin "$new_username"

For Debian/Ubuntu

echo "$new_username:$new_password" | chpasswd

For OpenSUSE

echo -e "$new_password\n$new_password" | passwd "$new_username"

You can't run two SQL statements into one like you are doing.

You can't "execute" a select query.

db is an object and you haven't set it to anything: (e.g. set db = currentdb)

In VBA integer types can hold up to max of 32767 - I would be tempted to use Long.

You might want to be a bit more specific about the date you are inserting:

INSERT INTO Test (Start_Date) VALUES ('#" & format(InDate, "mm/dd/yyyy") & "#' );"

After hours of searching, and no luck with the suggestions above, this worked like to a charm for 3.x+

override func viewDidLoad() {
        super.viewDidLoad()


            requestAuthorization()

}

func requestAuthorization() {

        if #available(iOS 10.0, *) {

            UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) { (granted, error) in
                print("Access granted: \(granted.description)")
            }

        } else {
            // Fallback on earlier versions
        }

    }

>>> names = ['King', 'Queen', 'Joker']
>>> any(n in 'King and john' for n in names)
True

>>> all(n in 'King and Queen' for n in names)
False

It just reduce several line of code into one. You don't have to write lengthy code like:

for n in names:
    if n in 'King and john':
       print True
    else:
       print False

It turns out, I was using the fetch method incorrectly.

fetch expects two parameters: an endpoint to the API, and an optional object which can contain body and headers.

I was wrapping the intended object within a second object, which did not get me any desired result.

Here's how it looks on a high level:

fetch('API_ENDPOINT', OBJECT)  
  .then(function(res) {
    return res.json();
   })
  .then(function(resJson) {
    return resJson;
   })

I structured my object as such:

var obj = {  
  method: 'POST',
  headers: {
    'Accept': 'application/json',
    'Content-Type': 'application/json',
    'Origin': '',
    'Host': 'api.producthunt.com'
  },
  body: JSON.stringify({
    'client_id': '(API KEY)',
    'client_secret': '(API SECRET)',
    'grant_type': 'client_credentials'
  })

There is another library lodash, it has clone and cloneDeep.

clone will clone your object but not create a new instance for non-primitive values, instead it will use the referrence to the original object

cloneDeep will create literally new objects without having any referrence to the original object, so it more safe when you have to change the object afterwards.

This one worked for me.

echo "$string" | tr xyz _

would replace each occurrence of x, y, or z with _, giving A__BC___DEF__LMN in your example.

echo "$string" | sed -r 's/[xyz]+/_/g'

would replace repeating occurrences of x, y, or z with a single _, giving A_BC_DEF_LMN in your example.

I accidentally discarded changes in the Source Control in VS Code, I just needed to reopen this file and press Ctrl-Z few times, glad that VS Code saves your changes like that.

You can also use ViewPager.SimpleOnPageChangeListener instead of ViewPager.OnPageChangeListener and override only those methods you want to use.

viewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

    // optional 
    @Override
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { }

    // optional 
    @Override
    public void onPageSelected(int position) { }

    // optional 
    @Override
    public void onPageScrollStateChanged(int state) { }
});

Hope this help :)

Edit: As per android APIs, setOnPageChangeListener (ViewPager.OnPageChangeListener listener) is deprecated. Please check this url:- Android ViewPager API

You may also use:

UsedRange.Rows.Count

It won't let me comment directly on the incorrect messages - but let me just warn everyone, that the definition of the /XN and /XO options are REVERSED compared to what has been posted in previous messages.

The Exclude Older/Newer files option is consistent with the information displayed in RoboCopy's logging: RoboCopy will iterate through the SOURCE and then report whether each file in the SOURCE is "OLDER" or "NEWER" than the file in the destination.

Consequently, /XO will exclude OLDER SOURCE files (which is intuitive), not "older than the source" as had been claimed here.

If you want to copy only new or changed source files, but avoid replacing more recent destination files, then /XO is the correct option to use.

When I faced this problem, I approached it like this: I created a DataRowView, grabbed the column index, and then used that in the row's ItemArray

DataRowView dataRow = (DataRowView)dataGrid1.SelectedItem;
int index = dataGrid1.CurrentCell.Column.DisplayIndex;
string cellValue = dataRow.Row.ItemArray[index].ToString();

If you really need to get it back into an array I find it easiest to convert the array to a list, expand the list then convert it back to an array.

        string[] myArray = new string[1] {"Element One"};
        // Convert it to a list
        List<string> resizeList = myArray.ToList();
        // Add some elements
        resizeList.Add("Element Two");
        // Back to an array
        myArray = resizeList.ToArray();
        // myArray has grown to two elements.

Both classes Rectangle and Ellipse need to override both of the abstract methods.

To work around this, you have 3 options:

• Add the two methods
• Make each class that extends Shape abstract

• Have a single method that does the function of the classes that will extend Shape, and override that method in Rectangle and Ellipse, for example:

  abstract class Shape {
      // ...
      void draw(Graphics g);
  }
  

And

    class Rectangle extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

Finally

    class Ellipse extends Shape {
        void draw(Graphics g) {
            // ...
        }
    }

And you can switch in between them, like so:

    Shape shape = new Ellipse();
    shape.draw(/* ... */);

    shape = new Rectangle();
    shape.draw(/* ... */);

Again, just an example.

A bit late to answer, but for who is searching. You can easily do this by using an extra property with the data annotation:

public string foo { get; set; }
public string bar { get; set; }

[MinLength(20, ErrorMessage = "too short")]
public string foobar 
{ 
    get
    {
        return foo + bar;
    }
}

That's all that is too it really. If you really want to display in a specific place the validation error as well, you can add this in your view:

@Html.ValidationMessage("foobar", "your combined text is too short")

doing this in the view can come in handy if you want to do localization.

Hope this helps!

You can simply use urljoin with relative root '/' as second argument:

import urllib.parse


url = 'https://stackoverflow.com/questions/9626535/get-protocol-host-name-from-url'
root_url = urllib.parse.urljoin(url, '/')
print(root_url)

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>>

Instead of using the referrer, you can implement window.postMessage to communicate accross iframes/windows across domains.
You post to window.parent, and then parent returns the URL.
This works, but it requires asynchronous communication.
You will have to write a synchronous wrapper around the asynchronous methods, if you need it synchronous.

To refresh page you don't need react-router, simple js:

window.location.reload();

To re-render view in React component, you can just fire update with props/state.

There's no need to set a fact.

    - shell: cat "hello"
      register: cat_contents

    - shell: echo "I cat hello"
      when: cat_contents.stdout == "hello"

You can do this,

User.query.filter_by(id=123).delete()

or

User.query.filter(User.id == 123).delete()

Make sure to commit for delete() to take effect.

You get this exact error should you pass an old school .xls file into this API. Save the .xls as a .xlsx and then it will work.

The answer is that java.sql.Timestamp is a mess and should be avoided. Use java.time.LocalDateTime instead.

So why is it a mess? From the java.sql.Timestamp JavaDoc, a java.sql.Timestamp is a "thin wrapper around java.util.Date that allows the JDBC API to identify this as an SQL TIMESTAMP value". From the java.util.Date JavaDoc, "the Date class is intended to reflect coordinated universal time (UTC)". From the ISO SQL spec a TIMESTAMP WITHOUT TIME ZONE "is a data type that is datetime without time zone". TIMESTAMP is a short name for TIMESTAMP WITHOUT TIME ZONE. So a java.sql.Timestamp "reflects" UTC while SQL TIMESTAMP is "without time zone".

Because java.sql.Timestamp reflects UTC its methods apply conversions. This causes no end of confusion. From the SQL perspective it makes no sense to convert a SQL TIMESTAMP value to some other time zone as a TIMESTAMP has no time zone to convert from. What does it mean to convert 42 to Fahrenheit? It means nothing because 42 does not have temperature units. It's just a bare number. Similarly you can't convert a TIMESTAMP of 2020-07-22T10:38:00 to Americas/Los Angeles because 2020-07-22T10:30:00 is not in any time zone. It's not in UTC or GMT or anything else. It's a bare date time.

java.time.LocalDateTime is also a bare date time. It does not have a time zone, exactly like SQL TIMESTAMP. None of its methods apply any kind of time zone conversion which makes its behavior much easier to predict and understand. So don't use java.sql.Timestamp. Use java.time.LocalDateTime.

LocalDateTime ldt = rs.getObject(col, LocalDateTime.class);
ps.setObject(param, ldt, JDBCType.TIMESTAMP);

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

With jQuery (and without FormData API) you can use something like this:

function readFile(file){
   var loader = new FileReader();
   var def = $.Deferred(), promise = def.promise();

   //--- provide classic deferred interface
   loader.onload = function (e) { def.resolve(e.target.result); };
   loader.onprogress = loader.onloadstart = function (e) { def.notify(e); };
   loader.onerror = loader.onabort = function (e) { def.reject(e); };
   promise.abort = function () { return loader.abort.apply(loader, arguments); };

   loader.readAsBinaryString(file);

   return promise;
}

function upload(url, data){
    var def = $.Deferred(), promise = def.promise();
    var mul = buildMultipart(data);
    var req = $.ajax({
        url: url,
        data: mul.data,
        processData: false,
        type: "post",
        async: true,
        contentType: "multipart/form-data; boundary="+mul.bound,
        xhr: function() {
            var xhr = jQuery.ajaxSettings.xhr();
            if (xhr.upload) {

                xhr.upload.addEventListener('progress', function(event) {
                    var percent = 0;
                    var position = event.loaded || event.position; /*event.position is deprecated*/
                    var total = event.total;
                    if (event.lengthComputable) {
                        percent = Math.ceil(position / total * 100);
                        def.notify(percent);
                    }                    
                }, false);
            }
            return xhr;
        }
    });
    req.done(function(){ def.resolve.apply(def, arguments); })
       .fail(function(){ def.reject.apply(def, arguments); });

    promise.abort = function(){ return req.abort.apply(req, arguments); }

    return promise;
}

var buildMultipart = function(data){
    var key, crunks = [], bound = false;
    while (!bound) {
        bound = $.md5 ? $.md5(new Date().valueOf()) : (new Date().valueOf());
        for (key in data) if (~data[key].indexOf(bound)) { bound = false; continue; }
    }

    for (var key = 0, l = data.length; key < l; key++){
        if (typeof(data[key].value) !== "string") {
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"; filename=\""+data[key].value[1]+"\"\r\n"+
                "Content-Type: application/octet-stream\r\n"+
                "Content-Transfer-Encoding: binary\r\n\r\n"+
                data[key].value[0]);
        }else{
            crunks.push("--"+bound+"\r\n"+
                "Content-Disposition: form-data; name=\""+data[key].name+"\"\r\n\r\n"+
                data[key].value);
        }
    }

    return {
        bound: bound,
        data: crunks.join("\r\n")+"\r\n--"+bound+"--"
    };
};

//----------
//---------- On submit form:
var form = $("form");
var $file = form.find("#file");
readFile($file[0].files[0]).done(function(fileData){
   var formData = form.find(":input:not('#file')").serializeArray();
   formData.file = [fileData, $file[0].files[0].name];
   upload(form.attr("action"), formData).done(function(){ alert("successfully uploaded!"); });
});

With FormData API you just have to add all fields of your form to FormData object and send it via $.ajax({ url: url, data: formData, processData: false, contentType: false, type:"POST"})

I encountered the same issue, when jdk 1.7 was used to compile then jre 1.4 was used for execution.

My solution was to set environment variable PATH by adding pathname C:\glassfish3\jdk7\bin in front of the existing PATH setting. The updated value is "C:\glassfish3\jdk7\bin;C:\Sun\SDK\bin". After the update, the problem was gone.

Here's how I usually do it. For example, to calculate 1717 mod 2:

• Take 1717 / 2. The answer is 858.5
• Now take 858 and multiply it by the mod (2) to get 1716
• Finally, subtract the original number (1717) minus the number you got from the previous step (1716) -- 1717-1716=1.

So 1717 mod 2 is 1.

To sum this up all you have to do is multiply the numbers before the decimal point with the mod then subtract it from the original number.

Retrieve nuget.exe from https://www.nuget.org/downloads. Copy it to a local folder and add that folder to the PATH environment variable.

This is will make nuget available globally, from any project.

Unlike other answers I'd additionally also add focus() along with scrollIntoView(). Also I'm using setTimeout since it jumps to top otherwise when changing the URL. Not sure what was the reason for that but it seems setTimeout does the workaround.

Origin:

<a [routerLink] fragment="some-id" (click)="scrollIntoView('some-id')">Jump</a>

Destination:

<a id="some-id" tabindex="-1"></a>

Typescript:

scrollIntoView(anchorHash) {
    setTimeout(() => {
        const anchor = document.getElementById(anchorHash);
        if (anchor) {
            anchor.focus();
            anchor.scrollIntoView();
        }
    });
}

Failure [INSTALL_FAILED_OLDER_SDK] basically means that the installation has failed due to the target location (AVD/Device) having an older SDK version than the targetSdkVersion specified in your app.

N/B Froyo 2.2 API 8

To fix this simply change

targetSdkVersion="17" to targetSdkVersion="8"

cheers.

After testing most of the switches this worked for me:

xcopy C:\folder1 C:\folder2\folder1 /t /e /i /y

This will copy the folder folder1 into the folder folder2. So the directory tree would look like:

C:
   Folder1
   Folder2
      Folder1

The problem was that the ID column wasn't getting any value. I saw on @Martin Smith SQL Fiddle that he declared the ID column with DEFAULT newid and I didn't..

DateTime now = DateTime.Now
string s = now.DayOfWeek.ToString();

The variable selectedHero is null in the template so you cannot bind selectedHero.name as is. You need to use the elvis operator ?. for this case:

<input [ngModel]="selectedHero?.name" (ngModelChange)="selectedHero.name = $event" />

The separation of the [(ngModel)] into [ngModel] and (ngModelChange) is also needed because you can't assign to an expression that uses the elvis operator.

I also think you mean to use:

<h2>{{selectedHero?.name}} details!</h2>

instead of:

<h2>{{hero.name}} details!</h2>

One refinement to some of these answers is to let CSS do more of the work.

The basic route seems to be:

1. Create a container element to hold the textarea and a hidden div
2. Using Javascript, keep the textarea’s contents synced with the div’s
3. Let the browser do the work of calculating the height of that div
4. Because the browser handles rendering / sizing the hidden div, we avoid explicitly setting the textarea’s height.

document.addEventListener('DOMContentLoaded', () => {_x000D_
    textArea.addEventListener('change', autosize, false)_x000D_
    textArea.addEventListener('keydown', autosize, false)_x000D_
    textArea.addEventListener('keyup', autosize, false)_x000D_
    autosize()_x000D_
}, false)_x000D_
_x000D_
function autosize() {_x000D_
    // Copy textarea contents to div browser will calculate correct height_x000D_
    // of copy, which will make overall container taller, which will make_x000D_
    // textarea taller._x000D_
    textCopy.innerHTML = textArea.value.replace(/\n/g, '<br/>')_x000D_
}

html, body, textarea {_x000D_
    font-family: sans-serif;_x000D_
    font-size: 14px;_x000D_
}_x000D_
_x000D_
.textarea-container {_x000D_
    position: relative;_x000D_
}_x000D_
_x000D_
.textarea-container > div, .textarea-container > textarea {_x000D_
    word-wrap: break-word; /* make sure the div and the textarea wrap words in the same way */_x000D_
    box-sizing: border-box;_x000D_
    padding: 2px;_x000D_
    width: 100%;_x000D_

_x000D_

On Ubuntu 18.04 , I tried a trick that I used to reactivate the file watching by ionic/node, and it works also here. This could be useful for those who don't have access to system conf files.

if your edit text already has a background then you can use following.

android:textCursorDrawable="@null"

From Android perspective: Method not available in api version

I was getting this Issue primarily because i was using some thing that is not available/deprecated in that Android version

Wrong way:

Notification.Builder nBuilder = new Notification.Builder(mContext);
nBuilder.addAction(new Notification.Action(android.R.drawable.ic_menu_view,"PAUSE",pendingIntent));

Right way:

Notification.Builder nBuilder = new Notification.Builder(mContext);
nBuilder.addAction(android.R.drawable.ic_media_pause,"PAUSE",pendingIntent);

here Notification.Action is not available prior to API 20 and my min version was API 16

You can use ax.figure.savefig():

import pandas as pd

s = pd.Series([0, 1])
ax = s.plot.hist()
ax.figure.savefig('demo-file.pdf')

This has no practical benefit over ax.get_figure().savefig() as suggested in Philip Cloud's answer, so you can pick the option you find the most aesthetically pleasing. In fact, get_figure() simply returns self.figure:

# Source from snippet linked above
def get_figure(self):
    """Return the `.Figure` instance the artist belongs to."""
    return self.figure

I use the html code tag after each line (see below) and it works for me.

• The token will expire after about 60 days.
• The token will be refreshed once per day, for up to 90 days, when the person using your app makes a request to Facebook's servers.
• All access tokens need to be renewed every 90 days with the consent of the person using your app.

Facebook change announce (10/04/2018)

Facebook updated token expiration page (10/04/2018)

offline_access: Enables your application to perform authorized requests on behalf of the user at any time. By default, most access tokens expire after a short time period to ensure applications only make requests on behalf of the user when the are actively using the application. This permission makes the access token returned by our OAuth endpoint long-lived.

Its a permission value requested.

offline_access permission has been removed a while ago.

I adopted the script from shiplu.mokadd.im to fit my needs. Whom it interests:

#!/bin/bash
if [ "$#" -lt 2 ]; then
    if [ "$#" -lt 1 ]; then 
        echo "usage: $0 [path to csv file] <table name> > [sql filename]"
        exit 1
    fi
    TABLENAME=$1
else
    TABLENAME=$2
fi
echo "CREATE TABLE $TABLENAME ( "
FIRSTLINE=$(head -1 $1)
# convert lowercase characters to uppercase
FIRSTLINE=$(echo $FIRSTLINE | tr '[:lower:]' '[:upper:]')
# remove spaces
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/ /_/g')
# add tab char to the beginning of line
FIRSTLINE=$(echo "\t$FIRSTLINE")
# add tabs and newline characters
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/,/,\\n\\t/g')
# add VARCHAR
FIRSTLINE=$(echo $FIRSTLINE | sed -e 's/,/ VARCHAR(255),/g')
# print out result
echo -e $FIRSTLINE" VARCHAR(255));"

git restore [filename_path]

For example I need to discard my last changes in index.html file:

git restore /usr/myPC/folder/index.html

How can I roll back my previous 4 commits locally in a branch?

Which means, you are not creating new branch and going into detached state. New way of doing that is:

git switch --detach revison

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

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

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

This is what I usually need in a script/function:

• default answer is Yes, if you hit ENTER
• accept also z (in case you mix up you are on QWERTZ Layout)
• accept other lanyuages ("ja", "Oui", ...)
• handle the right exit in case you are inside a function

while true; do
    read -p "Continue [Y/n]? " -n 1 -r -e yn
    case "${yn:-Y}" in
        [YyZzOoJj]* ) echo; break ;;
        [Nn]* ) [[ "$0" = "$BASH_SOURCE" ]] && exit 1 || return 1 ;; # handle exits from shell or function but don't exit interactive shell
        * ) echo "Please answer yes or no.";;
    esac
done
echo "and off we go!"

As a supplement,

1, Carriage return: It's a printer terminology meaning changing the print location to the beginning of current line. In computer world, it means return to the beginning of current line in most cases but stands for new line rarely.

2, Line feed: It's a printer terminology meaning advancing the paper one line. So Carriage return and Line feed are used together to start to print at the beginning of a new line. In computer world, it generally has the same meaning as newline.

3, Form feed: It's a printer terminology, I like the explanation in this thread.

If you were programming for a 1980s-style printer, it would eject the paper and start a new page. You are virtually certain to never need it.

http://en.wikipedia.org/wiki/Form_feed

It's almost obsolete and you can refer to Escape sequence \f - form feed - what exactly is it? for detailed explanation.

Note, we can use CR or LF or CRLF to stand for newline in some platforms but newline can't be stood by them in some other platforms. Refer to wiki Newline for details.

LF: Multics, Unix and Unix-like systems (Linux, OS X, FreeBSD, AIX, Xenix, etc.), BeOS, Amiga, RISC OS, and others

CR: Commodore 8-bit machines, Acorn BBC, ZX Spectrum, TRS-80, Apple II family, Oberon, the classic Mac OS up to version 9, MIT Lisp Machine and OS-9

RS: QNX pre-POSIX implementation

0x9B: Atari 8-bit machines using ATASCII variant of ASCII (155 in decimal)

CR+LF: Microsoft Windows, DOS (MS-DOS, PC DOS, etc.), DEC TOPS-10, RT-11, CP/M, MP/M, Atari TOS, OS/2, Symbian OS, Palm OS, Amstrad CPC, and most other early non-Unix and non-IBM OSes

LF+CR: Acorn BBC and RISC OS spooled text output.

So far as I know there's no single function which does this (maybe you were looking for the inverse of MapPath?). I'd love to know if such a function exists. Until then, I would just take the filename(s) returned by GetFiles, remove the path, and prepend the URL root. This can be done generically.

Update the tensorflow binary for your CPU & OS using this command

The humanize app offers a nice and a quick way of formatting a number but if you need to use a separator different from the comma, it's simple to just reuse the code from the humanize app, replace the separator char, and create a custom filter. For example, use space as a separator:

@register.filter('intspace')
def intspace(value):
    """
    Converts an integer to a string containing spaces every three digits.
    For example, 3000 becomes '3 000' and 45000 becomes '45 000'.
    See django.contrib.humanize app
    """
    orig = force_unicode(value)
    new = re.sub("^(-?\d+)(\d{3})", '\g<1> \g<2>', orig)
    if orig == new:
        return new
    else:
        return intspace(new)

Another simple way (Bootstrap 4) to work with multiple dropdowns

    $('.dropdown-item').on('click',  function(){
        var btnObj = $(this).parent().siblings('button');
        $(btnObj).text($(this).text());
        $(btnObj).val($(this).text());
    });

For Python 2.7:

>>> import datetime
>>> import time
>>> x = time.strptime('00:01:00,000'.split(',')[0],'%H:%M:%S')
>>> datetime.timedelta(hours=x.tm_hour,minutes=x.tm_min,seconds=x.tm_sec).total_seconds()
60.0

Currently, i prefer using this methods:

String data = "Date from Register: ";
        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
// Verify that OS.Version is > API 26 (OREO)
            DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyyMMdd"); 
// Origin format
            LocalDate localDate = LocalDate.parse(capitalModels.get(position).getDataServer(), formatter); // Parse String (from server) to LocalDate
            DateTimeFormatter formatter1 = DateTimeFormatter.ofPattern("dd/MM/yyyy"); 
//Output format
            data = "Data de Registro: "+formatter1.format(localDate); // Output
            Toast.makeText(holder.itemView.getContext(), data, Toast.LENGTH_LONG).show();
        }else{ 
//Same resolutions, just use legacy methods to oldest android OS versions.
                SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd",Locale.getDefault());
            try {
                Date date = format.parse(capitalModels.get(position).getDataServer());
                SimpleDateFormat formatter = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
                data = "Date from Register: "+formatter.format(date);
            } catch (ParseException e) {
                e.printStackTrace();
            }
        }

To make this simple, you have two options to reapply your stash:

1. git stash pop - Restore back to the saved state, but it deletes the stash from the temporary storage.
2. git stash apply - Restore back to the saved state and leaves the stash list for possible later reuse.

You can read in more detail about git stashes in this article.

You shouldn't change the stack. Android back button should work as in a web browser.

I can think of a way to do it, but it's quite a hack.

• Make your Activities singleTask by adding it to the AndroidManifest Example:

  <activity android:name=".activities.A"
            android:label="@string/A_title"
            android:launchMode="singleTask"/>
  
  <activity android:name=".activities.B"
            android:label="@string/B_title"
            android:launchMode="singleTask"/>
  

• Extend Application which will hold the logic of where to go.

Example:

public class DontHackAndroidLikeThis extends Application {

  private Stack<Activity> classes = new Stack<Activity>();

  public Activity getBackActivity() {
    return classes.pop();
  }

  public void addBackActivity(Activity activity) {
    classes.push(activity);
  }
}

From A to B:

DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
app.addBackActivity(A.class); 
startActivity(this, B.class);

From B to C:

DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
app.addBackActivity(B.class); 
startActivity(this, C.class);

In C:

If ( shouldNotGoBackToB() ) {
  DontHackAndroidLikeThis app = (DontHackAndroidLikeThis) getApplication();
  app.pop();
}

and handle the back button to pop() from the stack.

Once again, you shouldn't do this :)

I use AngularJS v1.3.4

        FileInputStream fileStream;
        try {
            fileStream = new FileInputStream(new File("C:\\xxxxx\\xxxxxx\\test.pdf"));

Today we use Bearer token more often that Basic Authentication but if you want to have Basic Authentication first to get Bearer token then there is a couple ways:

const request = new XMLHttpRequest();
request.open('GET', url, false, username,password)
request.onreadystatechange = function() {
        // D some business logics here if you receive return
   if(request.readyState === 4 && request.status === 200) {
       console.log(request.responseText);
   }
}
request.send()

Full syntax is here

Second Approach using Ajax:

$.ajax
({
  type: "GET",
  url: "abc.xyz",
  dataType: 'json',
  async: false,
  username: "username",
  password: "password",
  data: '{ "key":"sample" }',
  success: function (){
    alert('Thanks for your up vote!');
  }
});

Hopefully, this provides you a hint where to start API calls with JS. In Frameworks like Angular, React, etc there are more powerful ways to make API call with Basic Authentication or Oauth Authentication. Just explore it.

It's complicated.

First of all, in this code

const p = new Promise((resolve) => {
    resolve(4);
});

the type of p is inferred as Promise<{}>. There is open issue about this on typescript github, so arguably this is a bug, because obviously (for a human), p should be Promise<number>.

Then, Promise<{}> is compatible with Promise<number>, because basically the only property a promise has is then method, and then is compatible in these two promise types in accordance with typescript rules for function types compatibility. That's why there is no error in whatever1.

But the purpose of async is to pretend that you are dealing with actual values, not promises, and then you get the error in whatever2 because {} is obvioulsy not compatible with number.

So the async behavior is the same, but currently some workaround is necessary to make typescript compile it. You could simply provide explicit generic argument when creating a promise like this:

const whatever2 = async (): Promise<number> => {
    return new Promise<number>((resolve) => {
        resolve(4);
    });
};

If you use apachectl to start or stop, then you can find it with this command

apachectl -t -D DUMP_RUN_CFG

ES6 Arrow Function returns an Object

the right ways

1. normal function return an object

const getUser = user => {return { name: user.name, age: user.age };};

const user = { name: "xgqfrms", age: 21 };

console.log(getUser(user));
//  {name: "xgqfrms", age: 21}

2. (js expressions )

const getUser = user => ({ name: user.name, age: user.age });

const user = { name: "xgqfrms", age: 21 };

console.log(getUser(user));
//  {name: "xgqfrms", age: 21}

To stop the service we must use the method stopService():

  Intent myService = new Intent(MainActivity.this, BackgroundSoundService.class);
  //startService(myService);
  stopService(myService);

then the method onDestroy() in the service is called:

  @Override
    public void onDestroy() {

        Log.i(TAG, "onCreate() , service stopped...");
    }

Here is a complete example including how to stop the service.

RST is sent by the side doing the active close because it is the side which sends the last ACK. So if it receives FIN from the side doing the passive close in a wrong state, it sends a RST packet which indicates other side that an error has occured.

  #!/bin.bash
for folder_to_go in $(find . -mindepth 1 -maxdepth 1 -type d \( -name "*" \) ) ; 
                                    # you can add pattern insted of * , here it goes to any folder 
                                    #-mindepth / maxdepth 1 means one folder depth   
do
cd $folder_to_go
  echo $folder_to_go "########################################## "
  
  whatever you want to do is here

cd ../ # if maxdepth/mindepath = 2,  cd ../../
done

#you can try adding many internal for loops with many patterns, this will sneak anywhere you want

I know that it's an old question, but you can change the Response using a parameter (P):

public class Response<P> implements Serializable{

private static final long serialVersionUID = 1L;

public enum MessageCode {
    SUCCESS, ERROR, UNKNOWN
}

private MessageCode code;
private String message;
private P payload;

...
public P getPayload() {
    return payload;
}

public void setPayload(P payload) {
    this.payload = payload;
}

}

The method would be

public Response<Departments> getDepartments(){...}

I can't try it now but it should works.

Otherwise it's possible to extends Response

@XmlRootElement    
public class DepResponse extends Response<Department> {<no content>}

My StreamEx library extends the functionality of Stream API. In particular it offers methods like append and prepend which solve this issue (internally they use concat). These methods can accept either another stream or collection or varargs array. Using my library your problem can be solved this way (note that x != 0 look strange for non-primitive stream):

Stream<Integer> stream = StreamEx.of(stream1)
             .filter(x -> !x.equals(0))
             .append(stream2)
             .filter(x -> !x.equals(1))
             .append(element)
             .filter(x -> !x.equals(2));

By the way there's also a shortcut for your filter operation:

Stream<Integer> stream = StreamEx.of(stream1).without(0)
                                 .append(stream2).without(1)
                                 .append(element).without(2);

Try this:

if (var date = new Date(yourDateString)) {
    // if you get here then you have a valid date       
}

You need to use the matplotlib API directly rather than going through the pylab interface. There's a good example here:

Both capture output and run on background with threading

As mentioned on this answer, if you capture the output with stdout= and then try to read(), then the process blocks.

However, there are cases where you need this. For example, I wanted to launch two processes that talk over a port between them, and save their stdout to a log file and stdout.

The threading module allows us to do that.

First, have a look at how to do the output redirection part alone in this question: Python Popen: Write to stdout AND log file simultaneously

Then:

main.py

#!/usr/bin/env python3

import os
import subprocess
import sys
import threading

def output_reader(proc, file):
    while True:
        byte = proc.stdout.read(1)
        if byte:
            sys.stdout.buffer.write(byte)
            sys.stdout.flush()
            file.buffer.write(byte)
        else:
            break

with subprocess.Popen(['./sleep.py', '0'], stdout=subprocess.PIPE, stderr=subprocess.PIPE) as proc1, \
     subprocess.Popen(['./sleep.py', '10'], stdout=subprocess.PIPE, stderr=subprocess.PIPE) as proc2, \
     open('log1.log', 'w') as file1, \
     open('log2.log', 'w') as file2:
    t1 = threading.Thread(target=output_reader, args=(proc1, file1))
    t2 = threading.Thread(target=output_reader, args=(proc2, file2))
    t1.start()
    t2.start()
    t1.join()
    t2.join()

sleep.py

#!/usr/bin/env python3

import sys
import time

for i in range(4):
    print(i + int(sys.argv[1]))
    sys.stdout.flush()
    time.sleep(0.5)

After running:

./main.py

stdout get updated every 0.5 seconds for every two lines to contain:

0
10
1
11
2
12
3
13

and each log file contains the respective log for a given process.

Tested on Ubuntu 18.04, Python 3.6.7.

One possible cause of this linker error can also be inline functions that are declared but not defined in a header file that is then included somewhere else. Inline functions have to be defined in every translation unit they are used in.

I struggled with this for a couple of hours, so I would like to add some clarifications for it, all the examples noted here, refers to cases where the data is loaded from the script itself, not something coming from a service or a database, so I would like to provide my experience for anyone having the same problem as I did.

Normally you save only the id of the desired option in your database, so... let's show it

service.js

myApp.factory('Models', function($http) {
var models = {};
models.allModels = function(options) {
    return $http.post(url_service, {options: options});
};

return models;
});

controller.js

myApp.controller('exampleController', function($scope, Models) {
$scope.mainObj={id_main: 1, id_model: 101};
$scope.selected_model = $scope.mainObj.id_model;
Models.allModels({}).success(function(data) {
    $scope.models = data; 
});
});

Finally the partial html model.html

Model: <select ng-model="selected_model" 
ng-options="model.id_model as model.name for model in models" ></select>

basically I wanted to point that piece "model.id_model as model.name for model in models" the "model.id_model" uses the id of the model for the value so that you can match with the "mainObj.id_model" which is also the "selected_model", this is just a plain value, also "as model.name" is the label for the repeater, finally "model in models" is just the regular cycle that we all know about.

Hope this helps somebody, and if it does, please vote up :D

The answers provided above are absolutely correct and worth to read but I just wanted to give a straight forward answer to the question.

The question asked is just a type conversion question and here its conversion from int data type to float data type and for that you can do it by the function :

float()

And for more details you can visit this page.

I did this way:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="actionMenuTextAppearance">@style/MenuTextAppearance</item>
    <item name="android:actionMenuTextAppearance">@style/MenuTextAppearance</item>
    <item name="actionMenuTextColor">@color/colorAccent</item>
</style>

<style name="MenuTextAppearance" >
    <item name="android:textAppearance">@android:style/TextAppearance.Large</item>
    <item name="android:textSize">20sp</item>
    <item name="android:textStyle">bold</item>
</style>

There is a single quote in $submitsubject or $submit_message

Why is this a problem?

The single quote char terminates the string in MySQL and everything past that is treated as a sql command. You REALLY don't want to write your sql like that. At best, your application will break intermittently (as you're observing) and at worst, you have just introduced a huge security vulnerability.

Imagine if someone submitted '); DROP TABLE private_messages; in submit message.

Your SQL Command would be:

INSERT INTO private_messages (to_id, from_id, time_sent, subject, message) 
        VALUES('sender_id', 'id', now(),'subjet','');

DROP TABLE private_messages;

Instead you need to properly sanitize your values.

AT A MINIMUM you must run each value through mysql_real_escape_string() but you should really be using prepared statements.

If you were using mysql_real_escape_string() your code would look like this:

if($_POST['submit_message']){

if($_POST['form_subject']==""){
    $submit_subject="(no subject)";
}else{
    $submit_subject=mysql_real_escape_string($_POST['form_subject']); 
}
$submit_message=mysql_real_escape_string($_POST['form_message']);
$sender_id = mysql_real_escape_string($_POST['sender_id']);

Here is a great article on prepared statements and PDO.

I had same problem in my organization.

After many attempts, I came to the following solution:

1. I applied to the system administrator to change the proxy authentication type from Kerberos to NTLM. I'm not sure if it was mandatory (I'm an ignoramus in this matter), but my application was approved.

2. After that I add Git setting

   git config --global http.proxyauthmethod ntlm

Only after that I was able to clone my repository

It's possible, use the structure below:

<li><a><span></span></a></li>
<li><a><span></span></a></li>

etc...

Where the <li> contains an <a> anchor tag that contains a span as shown above. Then insert the following css:

• LI get position: relative;
• Give <a> tag a height, width
• Set <span> width & height to 100%, so that both <a> and <span> have same dimensions
• Both <a> and <span> get position: relative;.
• Assign the same background image to each element
• <a> tag will have the 'OFF' background-position, and the <span> will have the 'ON' background-poisiton.
• For 'OFF' state use opacity 0 for <span>
• For 'ON' :hover state use opacity 1 for <span>
• Set the -webkit or -moz transition on the <span> element

You'll have the ability to use the transition effect while still defaulting to the old background-position swap. Don't forget to insert IE alpha filter.

Java documentation is helpful to know the root cause of a particular IOException.

Just have a look at the direct known sub-interfaces of IOException from the documentation page:

ChangedCharSetException, CharacterCodingException, CharConversionException, ClosedChannelException, EOFException, FileLockInterruptionException, FileNotFoundException, FilerException, FileSystemException, HttpRetryException, IIOException, InterruptedByTimeoutException, InterruptedIOException, InvalidPropertiesFormatException, JMXProviderException, JMXServerErrorException, MalformedURLException, ObjectStreamException, ProtocolException, RemoteException, SaslException, SocketException, SSLException, SyncFailedException, UnknownHostException, UnknownServiceException, UnsupportedDataTypeException, UnsupportedEncodingException, UserPrincipalNotFoundException, UTFDataFormatException, ZipException

Most of these exceptions are self-explanatory.

A few IOExceptions with root causes:

EOFException: Signals that an end of file or end of stream has been reached unexpectedly during input. This exception is mainly used by data input streams to signal the end of the stream.

SocketException: Thrown to indicate that there is an error creating or accessing a Socket.

RemoteException: A RemoteException is the common superclass for a number of communication-related exceptions that may occur during the execution of a remote method call. Each method of a remote interface, an interface that extends java.rmi.Remote, must list RemoteException in its throws clause.

UnknownHostException: Thrown to indicate that the IP address of a host could not be determined (you may not be connected to Internet).

MalformedURLException: Thrown to indicate that a malformed URL has occurred. Either no legal protocol could be found in a specification string or the string could not be parsed.

You should use Asset Catalog:

I have investigated, how we can use Asset Catalog; Now it seems to be easy for me. I want to show you steps to add icons and splash in asset catalog.

Note: No need to make any entry in info.plist file :) And no any other configuration.

In below image, at right side, you will see highlighted area, where you can mention which icons you need. In case of mine, i have selected first four checkboxes; As its for my app requirements. You can select choices according to your requirements.

Now, see below image. As you will select any App icon then you will see its detail at right side selected area. It will help you to upload correct resolution icon.

If Correct resolution image will not be added then following warning will come. Just upload the image with correct resolution.

After uploading all required dimensions, you shouldn't get any warning.

You can declare the field as a first-class attribute of your form and just set choices dynamically:

class WaypointForm(forms.Form):
    waypoints = forms.ChoiceField(choices=[])

    def __init__(self, user, *args, **kwargs):
        super().__init__(*args, **kwargs)
        waypoint_choices = [(o.id, str(o)) for o in Waypoint.objects.filter(user=user)]
        self.fields['waypoints'].choices = waypoint_choices

You can also use a ModelChoiceField and set the queryset on init in a similar manner.

It looks that you had done all setup properly but there might be one area where it might be causing problem

Check the value of your "CLASSPATH" variable and make sure at the end you kept ;.

Note: ; is for end separator . is for including existing path at the end

Probably not the most efficient, but think it's a neat way to do it.

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true"));
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "false"));

    }

    static Int32 CountAllTheTimesThisStringAppearsInThatString(string orig, string find)
    {
        var s2 = orig.Replace(find,"");
        return (orig.Length - s2.Length) / find.Length;
    }
}

Another solution using java.util.Base64 with Spring Boot

Encryptor Class

    @Value("${security.encryptor.key}")
    private byte[] key;
    @Value("${security.encryptor.algorithm}")
    private String algorithm;

    public String encrypt(String plainText) throws Exception {
        SecretKeySpec secretKey = new SecretKeySpec(key, algorithm);
        Cipher cipher = Cipher.getInstance(algorithm);
        cipher.init(Cipher.ENCRYPT_MODE, secretKey);
        return new String(Base64.getEncoder().encode(cipher.doFinal(plainText.getBytes(StandardCharsets.UTF_8))));
    }

    public String decrypt(String cipherText) throws Exception {
        SecretKeySpec secretKey = new SecretKeySpec(key, algorithm);
        Cipher cipher = Cipher.getInstance(algorithm);
        cipher.init(Cipher.DECRYPT_MODE, secretKey);
        return new String(cipher.doFinal(Base64.getDecoder().decode(cipherText)));
    }
}

EncryptorController Class

I think this is the Easiest way to populate/model a table with ResultSet.. Download and include rs2xml.jar Get rs2xml.jar in your libraries..

import net.proteanit.sql.DbUtils;

    try
    {
    CreateConnection();
    PreparedStatement st =conn.prepareStatement("Select * from ABC;");
    ResultSet rs = st.executeQuery();
    tblToBeFilled.setModel(DbUtils.resultSetToTableModel(rs));
    conn.close();
    }
    catch(Exception ex)
    {
    JOptionPane.showMessageDialog(null, ex.toString());
    }

1. grant privileges

mysql> GRANT ALL PRIVILEGES ON . TO 'root'@'%'WITH GRANT OPTION;

mysql> FLUSH PRIVILEGES

2. check user table:

mysql> use mysql

mysql> select host,user from user

3.Modify the configuration file

mysql default bind ip:127.0.0.1, if we want to remote visit services,just delete config

#Modify the configuration file
vi /usr/local/etc/my.cnf

#Comment out the ip-address option
[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1

4.finally restart the services

brew services restart mysql

I don't think that they are standardised macros. There are standardised functions for floating point already, fmax and fmin (and fmaxf for floats, and fmaxl for long doubles).

You can implement them as macros as long as you are aware of the issues of side-effects/double-evaluation.

#define MAX(a,b) ((a) > (b) ? a : b)
#define MIN(a,b) ((a) < (b) ? a : b)

In most cases, you can leave it to the compiler to determine what you're trying to do and optimise it as best it can. While this causes problems when used like MAX(i++, j++), I doubt there is ever much need in checking the maximum of incremented values in one go. Increment first, then check.

(Update: a few years later Google and Qwant "airlines" still send me here when searching for "git non-default ssh port") A probably better way in newer git versions is to use the GIT_SSH_COMMAND ENV.VAR like:

GIT_SSH_COMMAND="ssh -oPort=1234 -i ~/.ssh/myPrivate_rsa.key" \ git clone myuser@myGitRemoteServer:/my/remote/git_repo/path

This has the added advantage of allowing any other ssh suitable option (port, priv.key, IPv6, PKCS#11 device, ...).

np.fromfile() has a sep= keyword argument:

Separator between items if file is a text file. Empty (“”) separator means the file should be treated as binary. Spaces (” ”) in the separator match zero or more whitespace characters. A separator consisting only of spaces must match at least one whitespace.

The default value of sep="" means that np.fromfile() tries to read it as a binary file rather than a space-separated text file, so you get nonsense values back. If you use np.fromfile('markers.txt', sep=" ") you will get the result you are looking for.

However, as others have pointed out, np.loadtxt() is the preferred way to convert text files to numpy arrays, and unless the file needs to be human-readable it is usually better to use binary formats instead (e.g. np.load()/np.save()).

SELECT * FROM service s WHERE s.service_id = ?;
BEGIN
   print 'no data'
END

Put your script in a file foo.py starting with

#!/usr/bin/python

Then give execute permission to that script using

chmod a+x foo.py

and use the full path of your foo.py file in your crontab.

See documentation of execve(2) which is handling the shebang.

JQuery 10.1.2 has a nice show and hide functions that encapsulate the behavior you are talking about. This would save you having to write a new function or keep track of css classes.

$("new").show();

$("new").hide();

Sometimes you need to include mysql db port id in the server like so.

$serverName = "127.0.0.1:3307";

While all these answer might have been correct in my scenario it didn't work. It all started when i uninstalled 2.* android studio version after getting 3.0rc1. But that screw up things and started getting this error. After that i did followed majority of these steps and none of them worked. While analyzing SDK directory i noticed that i have two platform tools folder. The .backup had adb.exe where as the other one didn't. I just copied the .backup files in the other platform-tool folder and it fixed my issue.

In short, services set to Automatic will start during the boot process, while services set to start as Delayed will start shortly after boot.

Starting your service Delayed improves the boot performance of your server and has security benefits which are outlined in the article Adriano linked to in the comments.

Update: "shortly after boot" is actually 2 minutes after the last "automatic" service has started, by default. This can be configured by a registry key, according to Windows Internals and other sources (3,4).

The registry keys of interest (At least in some versions of windows) are:

• HKLM\SYSTEM\CurrentControlSet\services\<service name>\DelayedAutostart will have the value 1 if delayed, 0 if not.
• HKLM\SYSTEM\CurrentControlSet\services\AutoStartDelay or HKLM\SYSTEM\CurrentControlSet\Control\AutoStartDelay (on Windows 10): decimal number of seconds to wait, may need to create this one. Applies globally to all Delayed services.

You can also use a background image replacement as an alternative, giving you total control over vertical and horizontal positioning.

See the answer to this Question

You could let your DataAdapter do the work. DataAdapter.Fill(DataTable) will append your new rows to any existing rows in DataTable.

Imagine it this way

*main() is also a function which is called by something else (like another FunctioN)

*the arguments to it is decided by the FunctioN

*the second argument is an array of strings

*the first argument is a number representing the number of strings

*do something with the strings

Maybe a example program woluld help.

int main(int argc,char *argv[])
{

    printf("you entered in reverse order:\n");

    while(argc--)
    {
        printf("%s\n",argv[argc]);
    }

return 0;
}

it just prints everything you enter as args in reverse order but YOU should make new programs that do something more useful.

compile it (as say hello) run it from the terminal with the arguments like

./hello am i here

then try to modify it so that it tries to check if two strings are reverses of each other or not then you will need to check if argc parameter is exactly three if anything else print an error

if(argc!=3)/*3 because even the executables name string is on argc*/
{
    printf("unexpected number of arguments\n");
    return -1;
}

then check if argv[2] is the reverse of argv[1] and print the result

./hello asdf fdsa

should output

they are exact reverses of each other

the best example is a file copy program try it it's like cp

cp file1 file2

cp is the first argument (argv[0] not argv[1]) and mostly you should ignore the first argument unless you need to reference or something

if you made the cp program you understood the main args really...

    final public void Call(View view){

    try {

        EditText editt=(EditText)findViewById(R.id.ed1);
        String str=editt.getText().toString();
        Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:"+str));
        startActivity(intent);
    }
    catch (android.content.ActivityNotFoundException e){

        Toast.makeText(getApplicationContext(),"App failed",Toast.LENGTH_LONG).show();
    }

Interestingly, http://maps.apple.com links will open directly in Apple Maps on an iOS device, or redirect to Google Maps otherwise (which is then intercepted on an Android device), so you can craft a careful URL that will do the right thing in both cases using an "Apple Maps" URL like:

http://maps.apple.com/?daddr=1600+Amphitheatre+Pkwy,+Mountain+View+CA

Alternatively, you can use a Google Maps url directly (without the /maps URL component) to open directly in Google Maps on an Android device, or open in Google Maps' Mobile Web on an iOS device:

http://maps.google.com/?daddr=1+Infinite+Loop,+Cupertino+CA

I assume that with interface you mean a C++ class with only pure virtual methods (i.e. without any code), instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable. e.g.:

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

In Windows programming, interfaces are fundamental in COM. In fact, a COM component exports only interfaces (i.e. pointers to v-tables, i.e. pointers to set of function pointers). This helps defining an ABI (Application Binary Interface) that makes it possible to e.g. build a COM component in C++ and use it in Visual Basic, or build a COM component in C and use it in C++, or build a COM component with Visual C++ version X and use it with Visual C++ version Y. In other words, with interfaces you have high decoupling between client code and server code.

Moreover, when you want to build DLL's with a C++ object-oriented interface (instead of pure C DLL's), as described in this article, it's better to export interfaces (the "mature approach") instead of C++ classes (this is basically what COM does, but without the burden of COM infrastructure).

I'd use an interface if I want to define a set of rules using which a component can be programmed, without specifying a concrete particular behavior. Classes that implement this interface will provide some concrete behavior themselves.

Instead, I'd use an abstract class when I want to provide some default infrastructure code and behavior, and make it possible to client code to derive from this abstract class, overriding the pure virtual methods with some custom code, and complete this behavior with custom code. Think for example of an infrastructure for an OpenGL application. You can define an abstract class that initializes OpenGL, sets up the window environment, etc. and then you can derive from this class and implement custom code for e.g. the rendering process and handling user input:

// Abstract class for an OpenGL app.
// Creates rendering window, initializes OpenGL; 
// client code must derive from it 
// and implement rendering and user input.
class OpenGLApp
{
public:
  OpenGLApp();
  virtual ~OpenGLApp();
  ...

  // Run the app    
  void Run();


  // <---- This behavior must be implemented by the client ---->

  // Rendering
  virtual void Render() = 0;

  // Handle user input
  // (returns false to quit, true to continue looping)
  virtual bool HandleInput() = 0;

  // <--------------------------------------------------------->


private:
  //
  // Some infrastructure code
  //
  ... 
  void CreateRenderingWindow();
  void CreateOpenGLContext();
  void SwapBuffers();
};


class MyOpenGLDemo : public OpenGLApp
{
public:
  MyOpenGLDemo();
  virtual ~MyOpenGLDemo();

  // Rendering
  virtual void Render();  // implements rendering code

  // Handle user input
  virtual bool HandleInput(); // implements user input handling


  //  ... some other stuff
};

Do as follows:

Project -> Properties -> java compiler ->

• Enable project specific settings - 'yes'
• Compiler compliance - 1.6
• generated class files and source compatibility - 1.5

I found the solution thanks to the link in Vincent's answer.

Maybe you can try the following :

var i = 0;
function AjaxSendForm(url, placeholder, form, append) {
var data = $(form).serialize();
append = (append === undefined ? false : true); // whatever, it will evaluate to true or false only
$.ajax({
    type: 'POST',
    url: url,
    data: data,
    beforeSend: function() {
        // setting a timeout
        $(placeholder).addClass('loading');
        i++;
    },
    success: function(data) {
        if (append) {
            $(placeholder).append(data);
        } else {
            $(placeholder).html(data);
        }
    },
    error: function(xhr) { // if error occured
        alert("Error occured.please try again");
        $(placeholder).append(xhr.statusText + xhr.responseText);
        $(placeholder).removeClass('loading');
    },
    complete: function() {
        i--;
        if (i <= 0) {
            $(placeholder).removeClass('loading');
        }
    },
    dataType: 'html'
});
}

This way, if the beforeSend statement is called before the complete statement i will be greater than 0 so it will not remove the class. Then only the last call will be able to remove it.

I cannot test it, let me know if it works or not.

The simplest way to create signed/unsigned APKs using Eclipse and ADT is as follows:

1. Right click your project in the "Project Explorer"
2. Hover over "Android Tools"
3. Select either "Export Signed Application Package" or "Export Unsigned Application Package"

4. Select the location for the new APK file and click "Save".

   • NOTE: If you're trying to build a APK for beta distribution, you'll probably need to create a signed package, which requires a keystore. If you follow the "Signed Application" process in Eclipse ADT it will guide you through the process of creating a new keystore.

Hope this helps.

Using <table> is not a bad choice. Of course it is bit old fashioned. 

But still not obsolete. But if you prefer you can use "Boostrap". There you have options for panels and enhanced forms.

This is the sample code for your requirement. Used minimal styles to simplify.

<!DOCTYPE html>
<html>
   <head>
      <title>Simple Login Form</title>
   </head>
   <style>
      table{
      border-style: solid;
      position: absolute;
      top: 40%;
      left : 40%;
      padding:10px;
      }
   </style>
   <body>
      <form method="post" action="login.php">
         <table>
            <tr bgcolor="black">
               <th colspan="3"><font color="white">Enter login details</th>
            </tr>
            <tr height="20"></tr>
            <tr>
               <td>User Name</td>
               <td>:</td>
               <td>
                  <input type="text" name="username"/>
               </td>
            </tr>
            <tr>

To make Python not return to me "Attempted relative import in non-package". package/

init.py subpackage1/ init.py moduleX.py moduleY.py subpackage2/ init.py moduleZ.py moduleA.py

This error occurs only if you are applying relative import to the parent file. For example parent file already returns main after you code "print(name)" in moduleA.py .so THIS file is already main it cannot return any parent package further on. relative imports are required in files of packages subpackage1 and subpackage2 you can use ".." to refer to the parent directory or module .But parent is if already top level package it cannot go further above that parent directory(package). Such files where you are applying relative importing to parents can only work with the application of absolute import. If you will use ABSOLUTE IMPORT IN PARENT PACKAGE NO ERROR will come as python knows who is at the top level of package even if your file is in subpackages because of the concept of PYTHON PATH which defines the top level of the project

Heh, I just wrote this (unrelated to this question):

string temp = "";
stringstream outStream;
double ratio = (currentImage->width*1.0f)/currentImage->height;
outStream << " R: " << ratio;
temp = outStream.str();

/* rest of the code */

Simple way is:

Math.Ceiling(decimal.Parse(yourNumber + ""));

Actually, this is NOT totally correct. I arrived at this page, trying to answer this question myself, as we are transitioning production GitLab server from http:// to https:// and most stuff is working as described above, but when you login to https://server and everything looks fine ... except when you browse to a project or repository, and it displays the SSH and HTTP instructions... It says "http" and the instructions it displays also say "http".

I found some more things to edit though:

/home/git/gitlab/config/gitlab.yml
  production: &base
    gitlab:
      host: git.domain.com

      # Also edit these:
      port: 443
      https: true
...

and

/etc/nginx/sites-available/gitlab
  server {
    server_name git.domain.com;

    # Also edit these:
    listen 443 ssl;
    ssl_certificate     /etc/ssl/certs/somecert.crt;
    ssl_certificate_key /etc/ssl/private/somekey.key;

...

The + (String Concatenation) does not work on SQL Server for the image, ntext, or text data types.

In fact, image, ntext, and text are all deprecated.

ntext, text, and image data types will be removed in a future version of MicrosoftSQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

That said if you are using an older version of SQL Server than you want to use UPDATETEXT to perform your concatenation. Which Colin Stasiuk gives a good example of in his blog post String Concatenation on a text column (SQL 2000 vs SQL 2005+).

You should run your entire script as superuser. If you want to run some command as non-superuser, use "-u" option of sudo:

#!/bin/bash

sudo -u username command1
command2
sudo -u username command3
command4

When running as root, sudo doesn't ask for a password.

Setting a line-height the same value as the height of the div will show one line of text vertically centered. In this example the height and line-height are 500px.

Example

JSFiddle

.circle {
  width: 500px;
  height: 500px;
  line-height: 500px;
  border-radius: 50%;
  font-size: 50px;
  color: #fff;
  text-align: center;
  background: #000
}

<div class="circle">Hello I am A Circle</div>

Use absolute positioning

.child-div {
    position:absolute;
    left:0;
    right:0;
}

After jQuery 1.6, using promise seems like a better option.

var $div1 = $('#div1');
var fadeOutDone = $div1.fadeOut().promise();
// do your logic here, e.g.fetch your 2nd image url
$.get('secondimageinfo.json').done(function(data){
  fadeoOutDone.then(function(){
    $div1.html('<img src="' + data.secondImgUrl + '" alt="'data.secondImgAlt'">');
    $div1.fadeIn();
  });
});

EDIT: Updated for jQuery 1.8

Since jQuery 1.8 browser specific transformations will be added automatically. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

I had a similar problem with the jQuery Thickbox (a lightbox-style dialog widget). The way I fixed my problem is as follows:

function setFocusThickboxIframe() {
    var iframe = $("#TB_iframeContent")[0];
    iframe.contentWindow.focus();
}

$(document).ready(function(){
   $("#id_cmd_open").click(function(){
      /*
         run thickbox code here to open lightbox,
         like tb_show("google this!", "http://www.google.com");
       */
      setTimeout(setFocusThickboxIframe, 100);
      return false;
   });
});

The code doesn't seem to work without the setTimeout(). Based on my testing, it works in Firefox3.5, Safari4, Chrome4, IE7 and IE6.

As you probably know, the maximum request length is configured in TWO places.

1. maxRequestLength - controlled at the ASP.NET app level
2. maxAllowedContentLength - under <system.webServer>, controlled at the IIS level

The first case is covered by other answers to this question.

To catch THE SECOND ONE you need to do this in global.asax:

protected void Application_EndRequest(object sender, EventArgs e)
{
    //check for the "file is too big" exception if thrown at the IIS level
    if (Response.StatusCode == 404 && Response.SubStatusCode == 13)
    {
        Response.Write("Too big a file"); //just an example
        Response.End();
    }
}

Got this error? Most of you are here because you didn't do the first thing that is: 1.Connect our Phone with the PC 2.Keep both PC and device connected to the same WiFi Then follow all the mentioned steps above.

I am facing a strange behavior.

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

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

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

>>> 'QH QD JC KD JS'.split()
['QH', 'QD', 'JC', 'KD', 'JS']

split:

Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). If maxsplit is not specified, then there is no limit on the number of splits (all possible splits are made).

If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings (for example, '1,,2'.split(',') returns ['1', '', '2']). The sep argument may consist of multiple characters (for example, '1<>2<>3'.split('<>') returns ['1', '2', '3']). Splitting an empty string with a specified separator returns [''].

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace. Consequently, splitting an empty string or a string consisting of just whitespace with a None separator returns [].

For example, ' 1 2 3 '.split() returns ['1', '2', '3'], and ' 1 2 3 '.split(None, 1) returns ['1', '2 3 '].

Hi below code is working fine.

 Cursor imagecursor1 = managedQuery(
    MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null,
    null, orderBy + " DESC");

   this.imageUrls = new ArrayList<String>();
  imageUrls.size();

   for (int i = 0; i < imagecursor1.getCount(); i++) {
   imagecursor1.moveToPosition(i);
   int dataColumnIndex = imagecursor1
     .getColumnIndex(MediaStore.Images.Media.DATA);
   imageUrls.add(imagecursor1.getString(dataColumnIndex));
  }

   options = new DisplayImageOptions.Builder()
  .showStubImage(R.drawable.stub_image)
  .showImageForEmptyUri(R.drawable.image_for_empty_url)
  .cacheInMemory().cacheOnDisc().build();

   imageAdapter = new ImageAdapter(this, imageUrls);

   gridView = (GridView) findViewById(R.id.PhoneImageGrid);
  gridView.setAdapter(imageAdapter);

You want to more clarifications. http://mylearnandroid.blogspot.in/2014/02/multiple-choose-custom-gallery.html

Just use indexOf:

haystack.indexOf(needle) >= 0

If you want to support old Internet Explorers (< IE9), you'll have to include your current code as a workaround though.

Unless your list is sorted, you need to compare every value to the needle. Therefore, both your solution and indexOf will have to execute n/2 comparisons on average. However, since indexOf is a built-in method, it may use additional optimizations and will be slightly faster in practice. Note that unless your application searches in lists extremely often (say a 1000 times per second) or the lists are huge (say 100k entries), the speed difference will not matter.

You can use this simple 'inline' method to construct a string_list_type parameter (works in SQL Server 2014):

declare @p1 dbo.string_list_type
insert into @p1 values(N'myFirstString')
insert into @p1 values(N'mySecondString')

Example use when executing a stored proc:

exec MyStoredProc @MyParam=@p1

It can't be done via CSS as CSS only changes the presentation (e.g. only Javascript can make the alert popup). I'd strongly recommend you check out a Javascript library called jQuery as it makes doing something like this trivial:

$(document).ready(function(){
  $("a").click(function(){
    alert("hohoho");
  });
});

You can use one of the many Arrays.binarySearch() methods. Keep in mind that the array must be sorted first.

One datestamp is already in the _id object, representing insert time

So if the insert time is what you need, it's already there:

Login to mongodb shell

Create your database by inserting items

> db.penguins.insert({"penguin": "skipper"})
> db.penguins.insert({"penguin": "kowalski"})

Lets make that database the one we are on now

> use penguins
switched to db penguins

Get the rows back:

> db.penguins.find()
{ "_id" : ObjectId("5498da1bf83a61f58ef6c6d5"), "penguin" : "skipper" }
{ "_id" : ObjectId("5498da28f83a61f58ef6c6d6"), "penguin" : "kowalski" }

Get each row in yyyy-MM-dd HH:mm:ss format:

> db.penguins.find().forEach(function (doc){ d = doc._id.getTimestamp(); print(d.getFullYear()+"-"+(d.getMonth()+1)+"-"+d.getDate() + " " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds()) })

If that last one-liner confuses you I have a walkthrough on how that works here: https://stackoverflow.com/a/27613766/445131

I know this question is old, but it's got a lot of attention over the years and I think it's missing a concept which may help someone in a similar case. I'm adding it here for completeness sake.

If you cannot modify your original database schema, then a lot of good answers have been provided and solve the problem just fine.

If you can, however, modify your schema, I would advise to add a field in your customer table that holds the id of the latest customer_data record for this customer:

CREATE TABLE customer (
  id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
  current_data_id INT UNSIGNED NULL DEFAULT NULL
);

CREATE TABLE customer_data (
   id INT UNSIGNED NOT NULL AUTO_INCREMENT PRIMARY KEY,
   customer_id INT UNSIGNED NOT NULL, 
   title VARCHAR(10) NOT NULL,
   forename VARCHAR(10) NOT NULL,
   surname VARCHAR(10) NOT NULL
);

Querying customers

Querying is as easy and fast as it can be:

SELECT c.*, d.title, d.forename, d.surname
FROM customer c
INNER JOIN customer_data d on d.id = c.current_data_id
WHERE ...;

The drawback is the extra complexity when creating or updating a customer.

Updating a customer

Whenever you want to update a customer, you insert a new record in the customer_data table, and update the customer record.

INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(2, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = 2;

Creating a customer

Creating a customer is just a matter of inserting the customer entry, then running the same statements:

INSERT INTO customer () VALUES ();

SET @customer_id = LAST_INSERT_ID();
INSERT INTO customer_data (customer_id, title, forename, surname) VALUES(@customer_id, 'Mr', 'John', 'Smith');
UPDATE customer SET current_data_id = LAST_INSERT_ID() WHERE id = @customer_id;

Wrapping up

The extra complexity for creating/updating a customer might be fearsome, but it can easily be automated with triggers.

Finally, if you're using an ORM, this can be really easy to manage. The ORM can take care of inserting the values, updating the ids, and joining the two tables automatically for you.

Here is how your mutable Customer model would look like:

class Customer
{
    private int id;
    private CustomerData currentData;

    public Customer(String title, String forename, String surname)
    {
        this.update(title, forename, surname);
    }

    public void update(String title, String forename, String surname)
    {
        this.currentData = new CustomerData(this, title, forename, surname);
    }

    public String getTitle()
    {
        return this.currentData.getTitle();
    }

    public String getForename()
    {
        return this.currentData.getForename();
    }

    public String getSurname()
    {
        return this.currentData.getSurname();
    }
}

And your immutable CustomerData model, that contains only getters:

class CustomerData
{
    private int id;
    private Customer customer;
    private String title;
    private String forename;
    private String surname;

    public CustomerData(Customer customer, String title, String forename, String surname)
    {
        this.customer = customer;
        this.title    = title;
        this.forename = forename;
        this.surname  = surname;
    }

    public String getTitle()
    {
        return this.title;
    }

    public String getForename()
    {
        return this.forename;
    }

    public String getSurname()
    {
        return this.surname;
    }
}

java.time has the Temporal interface which you can use to create Instant objects from most of the the time classes. Instant represents milliseconds on the timeline in the Epoch - the base reference for all other dates and times.

We need to convert the Date into a ZonedDateTime, with a Time and a Zone, to do the conversion:

LocalDate ldate = ...;
Instant instant = Instant.from(ldate.atStartOfDay(ZoneId.of("GMT")));
Date date = Date.from(instant);

There are multiple popular repositories offering docker packages for Ubuntu. The package docker.io is (most likely) from the Ubuntu repository. Another popular one is http://get.docker.io/ubuntu which offers a package lxc-docker (I am running the latter because it ships updates faster). Make sure only one package is installed. Not quite sure if removal of the packages cleans up properly. If sudo service docker restart still does not work, you may have to clean up manually in /etc/.

Cameron MacFarland nailed it.

I'd like to add that the .NET 4.0 client profile will be included in Windows Update and future Windows releases. Expect most computers to have the client profile, not the full profile. Do not underestimate that fact if you're doing business-to-consumer (B2C) sales.

Swift 5

Use Segue to perform navigation from one View Controller to another View Controller:

performSegue(withIdentifier: "idView", sender: self)

This works on Xcode 10.2.

You need to add the following attribute for the Activity in your AndroidManifest.xml.

<activity
    ...
    android:windowSoftInputMode="stateHidden|adjustResize"
    ...
/>

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

svn revert -R .
svn up

This will recursively revert the current directory and everything under it and then update to the latest version.

Problem With Android O API 26

If you stop the service right away (so your service does not actually really runs (wording / comprehension) and you are way under the ANR interval, you still need to call startForeground before stopSelf

https://plus.google.com/116630648530850689477/posts/L2rn4T6SAJ5

Tried this Approach But it Still creates an error:-

if (Util.SDK_INT > 26) {
    mContext.startForegroundService(playIntent);
} else {
    mContext.startService(playIntent);
}

I Am Using this until the Error is Resolved

mContext.startService(playIntent);

You need to update the package list in your Ubuntu:

$ sudo apt-get update
$ sudo apt-get install <package_name>

String(format: "%.2f", Double(round(1000*34.578)/1000))

Output: 34.58

You can do it in this way with Swift 3.0:

let date = Date()
let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day], from: date)

let year =  components.year
let month = components.month
let day = components.day

print(year)
print(month)
print(day)

you can use equals() method to statisfy your demands. == in java programming language has a different meaning!

I know this is an old post, however I thought I'd share the method I use to remove new line characters.

s.Replace(Environment.NewLine, "");

Separation of presentation and data drives my commit messages here.

Your commit message should not be hard-wrapped at any character count and instead line breaks should be used to separate thoughts, paragraphs, etc. as part of the data, not the presentation. In this case, the "data" is the message you are trying to get across and the "presentation" is how the user sees that.

I use a single summary line at the top and I try to keep it short but I don't limit myself to an arbitrary number. It would be far better if Git actually provided a way to store summary messages as a separate entity from the message but since it doesn't I have to hack one in and I use the first line break as the delimiter (luckily, many tools support this means of breaking apart the data).

For the message itself newlines indicate something meaningful in the data. A single newline indicates a start/break in a list and a double newline indicates a new thought/idea.

This is a summary line, try to keep it short and end with a line break.
This is a thought, perhaps an explanation of what I have done in human readable format.  It may be complex and long consisting of several sentences that describe my work in essay format.  It is not up to me to decide now (at author time) how the user is going to consume this data.

Two line breaks separate these two thoughts.  The user may be reading this on a phone or a wide screen monitor.  Have you ever tried to read 72 character wrapped text on a device that only displays 60 characters across?  It is a truly painful experience.  Also, the opening sentence of this paragraph (assuming essay style format) should be an intro into the paragraph so if a tool chooses it may want to not auto-wrap and let you just see the start of each paragraph.  Again, it is up to the presentation tool not me (a random author at some point in history) to try to force my particular formatting down everyone else's throat.

Just as an example, here is a list of points:
* Point 1.
* Point 2.
* Point 3.

Here's what it looks like in a viewer that soft wraps the text.

My suspicion is that the author of Git commit message recommendation you linked has never written software that will be consumed by a wide array of end-users on different devices before (i.e., a website) since at this point in the evolution of software/computing it is well known that storing your data with hard-coded presentation information is a bad idea as far as user experience goes.

Actually it is rather easy. Just think for the optimal way. I beleive the optimal way is:

for (int i=0; i<list.size(); i++) {
   Level obj = list.get(i);

   //Here execute yr code that may add / or may not add new element(s)
   //...

   i=list.indexOf(obj);
}

The following example works perfectly in the most logical case - when you dont need to iterate the added new elements before the iteration element. About the added elements after the iteration element - there you might want not to iterate them either. In this case you should simply add/or extend yr object with a flag that will mark them not to iterate them.

Get rid of the position:relative; and replace it with float:left; and float:right;.

Before the body of the constructor is run, all of the constructors for its parent class and then for its fields are invoked. By default, the no-argument constructors are invoked. Initialization lists allow you to choose which constructor is called and what arguments that constructor receives.

If you have a reference or a const field, or if one of the classes used does not have a default constructor, you must use an initialization list.

You need nunique:

df = df.groupby('domain')['ID'].nunique()

print (df)
domain
'facebook.com'    1
'google.com'      1
'twitter.com'     2
'vk.com'          3
Name: ID, dtype: int64

If you need to strip ' characters:

df = df.ID.groupby([df.domain.str.strip("'")]).nunique()
print (df)
domain
facebook.com    1
google.com      1
twitter.com     2
vk.com          3
Name: ID, dtype: int64

Or as Jon Clements commented:

df.groupby(df.domain.str.strip("'"))['ID'].nunique()

You can retain the column name like this:

df = df.groupby(by='domain', as_index=False).agg({'ID': pd.Series.nunique})
print(df)
    domain  ID
0       fb   1
1      ggl   1
2  twitter   2
3       vk   3

The difference is that nunique() returns a Series and agg() returns a DataFrame.

UPDATE `salary_generation_tbl` SET
    `modified_by` = IF(
        LOCATE('$', `other_salary_string`) > 0,
        SUBSTRING(`other_salary_string`, 1, LOCATE('$', `other_salary_string`) - 1),
        `other_salary_string`
    ),
    `other_salary` = IF(
        LOCATE('$', `other_salary_string`) > 0,
        SUBSTRING(`other_salary_string`, LOCATE('$', `other_salary_string`) + 1),
        NULL
    );

You should be able to use non-greedy quantifiers, specifically *?. You're going to probably want the following:

Pattern MY_PATTERN = Pattern.compile("\\[(.*?)\\]");

This will give you a pattern that will match your string and put the text within the square brackets in the first group. Have a look at the Pattern API Documentation for more information.

To extract the string, you could use something like the following:

Matcher m = MY_PATTERN.matcher("FOO[BAR]");
while (m.find()) {
    String s = m.group(1);
    // s now contains "BAR"
}

Right I think I know what you mean so lets see....

HTML:

<div id="con">
   <div id="content">Results will go here</div>
   <div id="footer">Footer will always be at the bottom</div>
</div>

CSS:

html,
body {
   margin:0;
   padding:0;
   height:100%;
}
div {
    outline: 1px solid;
}
#con {
   min-height:100%;
   position:relative;
}
#content {
   height: 1000px; /* Changed this height */
   padding-bottom:60px;
}
#footer {
   position:absolute;
   bottom:0;
   width:100%;
   height:60px;
}

This demo have the height of contentheight: 1000px; so you can see what it would look like scrolling down the bottom.

DEMO HERE

This demo has the height of content height: 100px; so you can see what it would look like with no scrolling.

DEMO HERE

So this will move the footer below the div content but if content is not bigger then the screen (no scrolling) the footer will sit at the bottom of the screen. Think this is what you want. Have a look and a play with it.

Updated fiddles so its easier to see with backgrounds.

Browsers with HTML5 support has files property for input type. This will of course not work in older IE versions.

var inpFiles = document.getElementById('#fileID');
for (var i = 0; i < inpFiles.files.length; ++i) {
    var size = inpFiles.files.item(i).size;
    alert("File Size : " + size);
}

I use the following command to reload Nginx (version 1.5.9) only if a configuration test was successful:

/etc/init.d/nginx configtest && sudo /etc/init.d/nginx reload

If you need to do this often, you may want to use an alias. I use the following:

alias n='/etc/init.d/nginx configtest && sudo /etc/init.d/nginx reload'

The trick here is done by the "&&" which only executes the second command if the first was successful. You can see here a more detailed explanation of the use of the "&&" operator.

You can use "restart" instead of "reload" if you really want to restart the server.
