Programs & Examples On #Simpledateformat

Update your format to:

SimpleDateFormat sdf=new SimpleDateFormat("E MMM dd hh:mm:ss Z yyyy");

tl;dr

Instant.now()                           // Capture the current moment in UTC.
.atZone( ZoneId.systemDefault() )       // Adjust into the JVM's current default time zone. Same moment, different wall-clock time. Produces a `ZonedDateTime` object.
.toInstant()                            // Extract a `Instant` (always in UTC) object from the `ZonedDateTime` object.
.atZone( ZoneId.of( "Europe/Paris" ) )  // Adjust the `Instant` into a specific time zone. Renders a `ZonedDateTime` object. Same moment, different wall-clock time.
.toInstant()                            // And back to UTC again.

java.time

The modern approach uses the java.time classes that supplanted the troublesome old legacy date-time classes (Date, Calendar, etc.).

Your use of the word "local" contradicts the usage in the java.time class. In java.time, "local" means any locality or all localities, but not any one particular locality. The java.time classes with names starting with "Local…" all lack any concept of time zone or offset-from-UTC. So they do not represent a specific moment, they are not a point on the timeline, whereas your Question is all about moments, points on the timeline viewed through various wall-clock times.

Get the current system time (local time)

If you want to capture the current moment in UTC, use Instant. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = Instant.now() ;  // Capture the current moment in UTC.

Adjust into a time zone by applying a ZoneId to get a ZonedDateTime. Same moment, same point on the timeline, different wall-clock time.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;  // Same moment, different wall-clock time.

As a shortcut, you can skip the usage of Instant to get a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;

Convert Local time to UTC // Works Fine Till here

You can adjust from the zoned date-time to UTC by extracting an Instant from a ZonedDateTime.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = ZonedDateTime.now( z ) ;
Instant instant = zdt.toInstant() ;

Reverse the UTC time, back to local time.

As shown above, apply a ZoneId to adjust the same moment into another wall-clock time used by the people of a certain region (a time zone).

Instant instant = Instant.now() ;  // Capture current moment in UTC.

ZoneId zDefault = ZoneId.systemDefault() ;  // The JVM's current default time zone.
ZonedDateTime zdtDefault = instant.atZone( zDefault ) ;

ZoneId zTunis = ZoneId.of( "Africa/Tunis" ) ;  // The JVM's current default time zone.
ZonedDateTime zdtTunis = instant.atZone( zTunis ) ;

ZoneId zAuckland = ZoneId.of( "Pacific/Auckland" ) ;  // The JVM's current default time zone.
ZonedDateTime zdtAuckland = instant.atZone( zAuckland ) ;

Going back to UTC from a zoned date-time, call ZonedDateTime::toInstant. Think of it conceptually as: ZonedDateTime = Instant + ZoneId.

Instant instant = zdtAuckland.toInstant() ;

All of these objects, the Instant and the three ZonedDateTime objects all represent the very same simultaneous moment, the same point in history.

Followed 3 different approaches (listed below) but all the 3 approaches retains the time in UTC only.

Forget about trying to fix code using those awful Date, Calendar, and GregorianCalendar classes. They are a wretched mess of bad design and flaws. You need never touch them again. If you must interface with old code not yet updated to java.time, you can convert back-and-forth via new conversion methods added to the old classes.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

For Java 8: You can use inbuilt java.time.format.DateTimeFormatter to reduce any chance of typos, like

DateTimeFormatter formatter = DateTimeFormatter.ISO_ZONED_DATE_TIME;

ISO_ZONED_DATE_TIME represents 2011-12-03T10:15:30+01:00[Europe/Paris] is one of the bundled standard DateTime formats provided by Oracle link

There's an error in the pattern of your SimpleDateFormat. it should be

SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm");

For converting date to string check this thread

Convert java.util.Date to String

And for converting string to date try this,

import java.text.ParseException;
import java.text.SimpleDateFormat;

public class StringToDate
{
    public static void main(String[] args) throws ParseException
    {
        SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss");
        String strDate = "14/03/2003 08:05:10";     
        System.out.println("Date - " + sdf.parse(strDate));
    }
}

try Parsing and Formatting

Take an example Parsing

String input = ...;
try {
    DateTimeFormatter formatter =
                      DateTimeFormatter.ofPattern("MMM d yyyy");
    LocalDate date = LocalDate.parse(input, formatter);
    System.out.printf("%s%n", date);
}
catch (DateTimeParseException exc) {
    System.out.printf("%s is not parsable!%n", input);
    throw exc;      // Rethrow the exception.
}

Formatting

ZoneId leavingZone = ...;
ZonedDateTime departure = ...;

try {
    DateTimeFormatter format = DateTimeFormatter.ofPattern("MMM d yyyy  hh:mm a");
    String out = departure.format(format);
    System.out.printf("LEAVING:  %s (%s)%n", out, leavingZone);
}
catch (DateTimeException exc) {
    System.out.printf("%s can't be formatted!%n", departure);
    throw exc;
}

The output for this example, which prints both the arrival and departure time, is as follows:

LEAVING:  Jul 20 2013  07:30 PM (America/Los_Angeles)
ARRIVING: Jul 21 2013  10:20 PM (Asia/Tokyo)

Use "E"

See the section on Date and Time Patterns:

JavaDocs for SimpleDateFormat

check the formats here http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

main

System.out.println("date  : " + new classname().getMyDate("2014-01-09 14:06", "dd-MMM-yyyy E hh:mm a z", "yyyy-MM-dd HH:mm"));

method

 public String getMyDate(String myDate, String returnFormat, String myFormat)
            {
                DateFormat dateFormat = new SimpleDateFormat(returnFormat);
                Date date=null;
                String returnValue="";
                try {
                    date = new SimpleDateFormat(myFormat, Locale.ENGLISH).parse(myDate);
                    returnValue = dateFormat.format(date);
                } catch (ParseException e) {
                    returnValue= myDate;
                    System.out.println("failed");
                    e.printStackTrace();
                }

            return returnValue;
            }

There are two answers above up-to-now and they are both long (and tl;dr too short IMHO), so I write summary from my experience starting to use new java.time library (applicable as noted in other answers to Java version 8+). ISO 8601 sets standard way to write dates: YYYY-MM-DD so the format of date-time is only as below (could be 0, 3, 6 or 9 digits for milliseconds) and no formatting string necessary:

import java.time.Instant;
public static void main(String[] args) {
    String date="2010-10-02T12:23:23Z";
    try {
        Instant myDate = Instant.parse(date);
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}

I did not need it, but as getting year is in code from the question, then:
it is trickier, cannot be done from Instant directly, can be done via Calendar in way of questions Get integer value of the current year in Java and Converting java.time to Calendar but IMHO as format is fixed substring is more simple to use:

myDate.toString().substring(0,4);

You are probably using a locale where the month names are not "January", "February", etc. but some other words in your local language.

Try specifying the locale you wish to use, for example Locale.US:

DateFormat fmt = new SimpleDateFormat("MMMM dd, yyyy", Locale.US);
Date d = fmt.parse("June 27,  2007");

Also, you have an extra space in the date string, but actually this has no effect on the result. It works either way.

Very Simple Example is.

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd-MM-yyyy");
                Date date = new Date();
                Date date1 = new Date();
            try {
                System.out.println("Date1:   "+date1);
                System.out.println("date" + date);

                date = simpleDateFormat.parse("01-01-2013");
                date1 = simpleDateFormat.parse("06-15-2013");

                System.out.println("Date1 is:"+date1);
                System.out.println("date" + date);

            } catch (Exception e) {
                System.out.println(e.getMessage());
            }

If you want to parse the format yourself you could do it easily with a regex such as

private static Pattern pattern = Pattern.compile("(\\d{2}):(\\d{2}):(\\d{2}).(\\d{3})");

public static long dateParseRegExp(String period) {
    Matcher matcher = pattern.matcher(period);
    if (matcher.matches()) {
        return Long.parseLong(matcher.group(1)) * 3600000L 
            + Long.parseLong(matcher.group(2)) * 60000 
            + Long.parseLong(matcher.group(3)) * 1000 
            + Long.parseLong(matcher.group(4)); 
    } else {
        throw new IllegalArgumentException("Invalid format " + period);
    }
}

However, this parsing is quite lenient and would accept 99:99:99.999 and just let the values overflow. This could be a drawback or a feature.

If you try to be aware of i18n the solution get even more complicated.

The problem is that in other languages the suffix may depend not only on the number itself, but also on the noun it counts. For example in Russian it would be "2-?? ????", but "2-?? ??????" (these mean "2nd day", but "2nd week"). This is not apply if we formatting only days, but in a bit more generic case you should be aware of complexity.

I think nice solution (I didn't have time to actually implement) would be to extend SimpleDateFormetter to apply Locale-aware MessageFormat before passing to the parent class. This way you would be able to support let say for March formats %M to get "3-rd", %MM to get "03-rd" and %MMM to get "third". From outside this class looks like regular SimpleDateFormatter, but supports more formats. Also if this pattern would be by mistake applied by regular SimpleDateFormetter the result would be incorrectly formatted, but still readable.

In the pattern, the inclusion of a 'z' date-time component indicates that timezone format needs to conform to the General time zone "standard", examples of which are Pacific Standard Time; PST; GMT-08:00.

A 'Z' indicates that the timezone conforms to the RFC 822 time zone standard, e.g. -0800.

I think you need a DatatypeConverter ...

@Test
public void testTimezoneIsGreenwichMeanTime() throws ParseException {
    final Calendar calendar = javax.xml.bind.DatatypeConverter.parseDateTime("2010-04-05T17:16:00Z");
    TestCase.assertEquals("gotten timezone", "GMT+00:00", calendar.getTimeZone().getID());
}

UPDATE My Answer here is now outdated. The Joda-Time project is now in maintenance mode, advising migration to the java.time classes. See the modern solution in the Answer by Ole V.V..

Joda-Time

The accepted answer by NidhishKrishnan is correct.

For fun, here is the same kind of code in Joda-Time 2.3.

// © 2013 Basil Bourque. This source code may be used freely forever by anyone taking full responsibility for doing so.
// import org.joda.time.*;
// import org.joda.time.format.*;

java.util.Date date = new Date(); // A Date object coming from other code.

// Pass the java.util.Date object to constructor of Joda-Time DateTime object.
DateTimeZone kolkataTimeZone = DateTimeZone.forID( "Asia/Kolkata" );
DateTime dateTimeInKolkata = new DateTime( date, kolkataTimeZone );

DateTimeFormatter formatter = DateTimeFormat.forPattern( "yyyy-MM-dd");
System.out.println( "dateTimeInKolkata formatted for date: " + formatter.print( dateTimeInKolkata ) );
System.out.println( "dateTimeInKolkata formatted for ISO 8601: " + dateTimeInKolkata );

When run…

dateTimeInKolkata formatted for date: 2013-12-17
dateTimeInKolkata formatted for ISO 8601: 2013-12-17T14:56:46.658+05:30

There is no direct function to get yesterday's date.

To get yesterday's date, you need to use Calendar by subtracting -1.

Use the style + locale: DateFormat.getDateInstance(int style, Locale locale)

Check http://java.sun.com/j2se/1.5.0/docs/api/java/text/DateFormat.html

Run the following example to see the differences:

import java.text.DateFormat;
import java.util.Date;
import java.util.Locale;

public class DateFormatDemoSO {
  public static void main(String args[]) {
    int style = DateFormat.MEDIUM;
    //Also try with style = DateFormat.FULL and DateFormat.SHORT
    Date date = new Date();
    DateFormat df;
    df = DateFormat.getDateInstance(style, Locale.UK);
    System.out.println("United Kingdom: " + df.format(date));
    df = DateFormat.getDateInstance(style, Locale.US);
    System.out.println("USA: " + df.format(date));   
    df = DateFormat.getDateInstance(style, Locale.FRANCE);
    System.out.println("France: " + df.format(date));
    df = DateFormat.getDateInstance(style, Locale.ITALY);
    System.out.println("Italy: " + df.format(date));
    df = DateFormat.getDateInstance(style, Locale.JAPAN);
    System.out.println("Japan: " + df.format(date));
  }
}

Output:

United Kingdom: 25-Sep-2017
USA: Sep 25, 2017
France: 25 sept. 2017
Italy: 25-set-2017
Japan: 2017/09/25

In response to: "How to convert Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México)) to dd-MM-yy in Java?", it was marked how duplicate

Try this: With java.util.Date, java.text.SimpleDateFormat, it's a simple solution.

public static void main(String[] args) throws ParseException {

    String fecha = "Tue Sep 13 2016 00:00:00 GMT-0500 (Hora de verano central (México))";
    Date f = new Date(fecha);

    SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy");
    sdf.setTimeZone(TimeZone.getTimeZone("-5GMT"));
    fecha = sdf.format(f);
    System.out.println(fecha);
}

Change HH to hh as

long timeInMillis = System.currentTimeMillis();
Calendar cal1 = Calendar.getInstance();
cal1.setTimeInMillis(timeInMillis);
SimpleDateFormat dateFormat = new SimpleDateFormat(
                                "dd/MM/yyyy hh:mm:ss a");
dateforrow = dateFormat.format(cal1.getTime());

Note that dd/mm/yyyy - will give you minutes instead of the month.

@John-Skeet gave me the clue to fix my own issue around this. As a younger programmer this small issue is easy to miss and hard to diagnose. So Im sharing it in the hopes it will help someone.

My issue was that I wanted to parse the following string contraining a time stamp from a JSON I have no influence over and put it in more useful variables. But I kept getting errors.

So given the following (pay attention to the string parameter inside ofPattern();

String str = "20190927T182730.000Z"

LocalDateTime fin;
fin = LocalDateTime.parse( str, DateTimeFormatter.ofPattern("yyyyMMdd'T'HHmmss.SSSZ") );

Error:

Exception in thread "main" java.time.format.DateTimeParseException: Text 
'20190927T182730.000Z' could not be parsed at index 19

The problem? The Z at the end of the Pattern needs to be wrapped in 'Z' just like the 'T' is. Change "yyyyMMdd'T'HHmmss.SSSZ" to "yyyyMMdd'T'HHmmss.SSS'Z'" and it works.

Removing the Z from the pattern alltogether also led to errors.

Frankly, I'd expect a Java class to have anticipated this.

tl;dr

what is the way to retrieve a Date object so that its always in GMT?

Instant.now() 

Details

You are using troublesome confusing old date-time classes that are now supplanted by the java.time classes.

Instant = UTC

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = Instant.now() ; // Current moment in UTC.

ISO 8601

To exchange this data as text, use the standard ISO 8601 formats exclusively. These formats are sensibly designed to be unambiguous, easy to process by machine, and easy to read across many cultures by people.

The java.time classes use the standard formats by default when parsing and generating strings.

String output = instant.toString() ;  

2017-01-23T12:34:56.123456789Z

Time zone

If you want to see that same moment as presented in the wall-clock time of a particular region, apply a ZoneId to get a ZonedDateTime.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!).

ZoneId z = ZoneId.of( "Asia/Singapore" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;  // Same simultaneous moment, same point on the timeline.

See this code live at IdeOne.com.

Notice the eight hour difference, as the time zone of Asia/Singapore currently has an offset-from-UTC of +08:00. Same moment, different wall-clock time.

instant.toString(): 2017-01-23T12:34:56.123456789Z

zdt.toString(): 2017-01-23T20:34:56.123456789+08:00[Asia/Singapore]

Convert

Avoid the legacy java.util.Date class. But if you must, you can convert. Look to new methods added to the old classes.

java.util.Date date = Date.from( instant ) ;

…going the other way…

Instant instant = myJavaUtilDate.toInstant() ;

Date-only

For date-only, use LocalDate.

LocalDate ld = zdt.toLocalDate() ;

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

use SimpleDateFormat to first parse() String to Date and then format() Date to String

Parse a time with timezone, Z in pattern is for time zone

String aTime = "2017-10-25T11:39:00+09:00";
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ", Locale.getDefault());
try {
    Calendar cal = Calendar.getInstance();
    cal.setTime(sdf.parse(aTime));
    Log.i(TAG, "time = " + cal.getTimeInMillis()); 
} catch (ParseException e) {
    e.printStackTrace();
}

Output: it will return the UTC time

1508899140000

If we don't set the time zone in pattern like yyyy-MM-dd'T'HH:mm:ss. SimpleDateFormat will use the time zone which have set in Setting

A SimpleDateFormat, as its name indicates, formats Dates. Not a Calendar. So, if you want to format a GregorianCalendar using a SimpleDateFormat, you must convert the Calendar to a Date first:

dateFormat.format(calendar.getTime());

And what you see printed is the toString() representation of the calendar. It's intended usage is debugging. It's not intended to be used to display a date in a GUI. For that, use a (Simple)DateFormat.

Finally, to convert from a String to a Date, you should also use a (Simple)DateFormat (its parse() method), rather than splitting the String as you're doing. This will give you a Date object, and you can create a Calendar from the Date by instanciating it (Calendar.getInstance()) and setting its time (calendar.setTime()).

My advice would be: Googling is not the solution here. Reading the API documentation is what you need to do.

Here is a code example that proves the fault in the class. I've checked: the problem occurs when using parse and also when you are only using format.

Implemented the same in scala, Please help urself with converting to Java, the core logic and functions used stays the same.

import java.text.SimpleDateFormat
import org.apache.commons.lang.time.DateUtils

object MultiDataFormat {
  def main(args: Array[String]) {

val dates =Array("2015-10-31","26/12/2015","19-10-2016")

val possibleDateFormats:Array[String] = Array("yyyy-MM-dd","dd/MM/yyyy","dd-MM-yyyy")

val sdf =  new SimpleDateFormat("yyyy-MM-dd") //change it as per the requirement
  for (date<-dates) {
    val outputDate = DateUtils.parseDateStrictly(date, possibleDateFormats)
    System.out.println("inputDate ==> " + date + ", outputDate ==> " +outputDate + " " + sdf.format(outputDate) )
  }
}

}

Calendar c = Calendar.getInstance();
int day = c.get(Calendar.DAY_OF_MONTH);
int month = c.get(Calendar.MONTH);
int year = c.get(Calendar.YEAR);
String date = day + "/" + (month + 1) + "/" + year;

Log.i("TAG", "--->" + date);

For future reference:

 yyyy => 4 digit year
 MM   => 2 digit month (you must type MM in ALL CAPS)
 dd   => 2 digit "day of the month"

 HH   => 2-digit "hour in day" (0 to 23)
 mm   => 2-digit minute (you must type mm in lowercase)
 ss   => 2-digit seconds
 SSS  => milliseconds

So "yyyy-MM-dd HH:mm:ss" returns "2018-01-05 09:49:32"

But "MMM dd, yyyy hh:mm a" returns "Jan 05, 2018 09:49 am"

The so-called examples at https://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html show only output. They do not tell you what formats to use!

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

String dateStr = "2016-09-17T08:14:03+00:00";
String s = dateStr.replace("Z", "+00:00");
s = s.substring(0, 22) + s.substring(23);
Date date = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").parse(s);
Timestamp createdOn = new Timestamp(date.getTime());
mcList.setCreated_on(createdOn);

Java 7 added support for time zone descriptors according to ISO 8601. This can be use in Java 7.

In one line:

String date=new SimpleDateFormat("MM-dd-yyyy").format(new SimpleDateFormat("yyyy-MM-dd").parse("2011-01-01"));

Where:

String date=new SimpleDateFormat("FinalFormat").format(new SimpleDateFormat("InitialFormat").parse("StringDate"));

In java 8 , It's really easy to get timestamp in UTC by using java 8 java.time.Instant library :

Instant.now();

That few word of code will return the UTC Timestamp.

Swift 3 & Swift 4

componentArray = Array(dict.keys) // for Dictionary

New is always used to allocate dynamic memory, which then has to be freed.

By doing the first option, that memory will be automagically freed when scope is lost.

Point p1 = Point(0,0); //This is if you want to be safe and don't want to keep the memory outside this function.

Point* p2 = new Point(0, 0); //This must be freed manually. with...
delete p2;

    return Optional.ofNullable(result)

Considering there might be several img tags I would recommend re.findall:

import re

with open("sample.txt", 'r') as f_in, open('writetest.txt', 'w') as f_out:
    for line in f_in:
        for img in re.findall('<img[^>]+>', line):
            print >> f_out, "yo it's a {}".format(img)

#include"stdio.h"//rmv coding for randam number access

#include"conio.h"

#include"time.h"

void main()
{
    time_t t;
    int rmvivek;

    srand(time(&t));
    rmvivek=1;

    while(rmvivek<=5)
    {
        printf("%c\t",rand()%10);
        rmvivek++;
    }
    getch();
}

For me it was case of having two beans implementing the same interface. One was a fake ban for the sake of unit test which was conflicting with original bean. If we use

@component("suggestionServicefake")

, it still references with suggestionService. So I removed @component and only used

@Qualifier("suggestionServicefake")

which solved the problem

You could try this solution :

In your location block when you use proxy_pass do something like this:

location ... {

  add_header yourHeaderName yourValue;
  proxy_pass xxxx://xxx_my_proxy_addr_xxx;

  # Now use this solution:
  proxy_ignore_headers yourHeaderName // but set by proxy

  # Or if above didn't work maybe this:
  proxy_hide_header yourHeaderName // but set by proxy

}

I'm not sure would it be exactly what you need but try some manipulation of this method and maybe result will fit your problem.

Also you can use this combination:

proxy_hide_header headerSetByProxy;
set $sent_http_header_set_by_proxy yourValue;

Here is my suggested validation:

var isValid = false;

// Check whether this entered value is numeric.
function checkNumeric() {
    var numericVal = document.getElementById("txt_numeric").value;

    if(isNaN(numericVal) || numericVal == "" || numericVal == null || numericVal.indexOf(' ') >= 0) {
        alert("Please, enter a numeric value!");
        isValid = false;
    } else {
        isValid = true;
    }
}

You need to concatenate your string.

document.getElementById(tabName).style.backgroundImage = 'url(buttons/' + imagePrefix + '.png)';

The way you had it, it's just making 1 long string and not actually interpreting imagePrefix.

I would even suggest creating the string separate:

function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
    var urlString = 'url(buttons/' + imagePrefix + '.png)';
    document.getElementById(tabName).style.backgroundImage =  urlString;
}

As mentioned by David Thomas below, you can ditch the double quotes in your string. Here is a little article to get a better idea of how strings and quotes/double quotes are related: http://www.quirksmode.org/js/strings.html

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

I use this way, you should put a backslash at the end of the directory name to avoid that place exists in a file without extension with the same name as the directory you specified, never use "C:\VTS" because it can a file exists with the name "VTS" saved in "C:" partition, the correct way is to use "C:\VTS\", check out the backslash after the VTS, so is the right way.

@echo off
@break off
@title Create folder with batch but only if it doesn't already exist - D3F4ULT
@color 0a
@cls

setlocal EnableDelayedExpansion

if not exist "C:\VTS\" (
  mkdir "C:\VTS\"
  if "!errorlevel!" EQU "0" (
    echo Folder created successfully
  ) else (
    echo Error while creating folder
  )
) else (
  echo Folder already exists
)

pause
exit

I ended here, because I googled for "python first and last element of array", and found everything else but this. So here's the answer to the title question:

a = [1,2,3]
a[0] # first element (returns 1)
a[-1] # last element (returns 3)

I had the same problem. Solved it by using a javascript library called FileSaver

Just call

saveAs(file, 'filename');

Full http post request:

$http.post('apiUrl', myObject, { responseType: 'arraybuffer' })
  .success(function(data) {
            var file = new Blob([data], { type: 'application/pdf' });
            saveAs(file, 'filename.pdf');
        });

Whatever you want to use from another module, just put it in the export array. Like this-

 @NgModule({
  declarations: [TaskCardComponent],
  exports: [TaskCardComponent],
  imports: [MdCardModule]
})

Requires PHP5.3:

$begin = new DateTime('2010-05-01');
$end = new DateTime('2010-05-10');

$interval = DateInterval::createFromDateString('1 day');
$period = new DatePeriod($begin, $interval, $end);

foreach ($period as $dt) {
    echo $dt->format("l Y-m-d H:i:s\n");
}

This will output all days in the defined period between $start and $end. If you want to include the 10th, set $end to 11th. You can adjust format to your liking. See the PHP Manual for DatePeriod.

here is a useful gist from lfmingo

OkHttpClient.Builder httpClient = new OkHttpClient.Builder();

httpClient.addInterceptor(new Interceptor() {

    @Override
    public Response intercept(Interceptor.Chain chain) throws IOException {
        Request original = chain.request();

        Request request = original.newBuilder()
            .header("User-Agent", "Your-App-Name")
            .header("Accept", "application/vnd.yourapi.v1.full+json")
            .method(original.method(), original.body())
            .build();

        return chain.proceed(request);
    }
}

OkHttpClient client = httpClient.build();

Retrofit retrofit = new Retrofit.Builder()  
    .baseUrl(API_BASE_URL)
    .addConverterFactory(GsonConverterFactory.create())
    .client(client)
    .build();

You can simply get the text size for a Paint object using getTextSize() method. For example:

Paint mTextPaint = new Paint (Paint.ANTI_ALIAS_FLAG);
//use densityMultiplier to take into account different pixel densities
final float densityMultiplier = getContext().getResources()
            .getDisplayMetrics().density;  
mTextPaint.setTextSize(24.0f*densityMultiplier);

//...

float size = mTextPaint.getTextSize();

Here are some very basic appearance customization that you can apply app wide:

UINavigationBar.appearance().backgroundColor = UIColor.greenColor()
UIBarButtonItem.appearance().tintColor = UIColor.magentaColor()
//Since iOS 7.0 UITextAttributeTextColor was replaced by NSForegroundColorAttributeName
UINavigationBar.appearance().titleTextAttributes = [UITextAttributeTextColor: UIColor.blueColor()]
UITabBar.appearance().backgroundColor = UIColor.yellowColor();

More about UIAppearance API in Swift you can read here: https://developer.apple.com/documentation/uikit/uiappearance

Some of the provided answers did not work for me (javaw.exe still running after closing the window) or, eclipse showed an exception after the application was closed.

On the other hand, this works perfectly:

primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    @Override
    public void handle(WindowEvent t) {
        Platform.exit();
        System.exit(0);
    }
});

Use a JSON library to parse the string and retrieve the value.

The following very basic example uses the built-in JSON parser from Android.

String jsonString = "{ \"name\" : \"John\", \"age\" : \"20\", \"address\" : \"some address\" }";
JSONObject jsonObject = new JSONObject(jsonString);
int age = jsonObject.getInt("age");

More advanced JSON libraries, such as jackson, google-gson, json-io or genson, allow you to convert JSON objects to Java objects directly.

Set to cookie in the main domain -

document.cookie = "key=value;domain=.mydomain.com"

and then take the data from any main domain or sub domain and set it on the localStorage

Please see this link.

I looked in all my apache log files until I found the actual error (I had changed the <VirtualHost> from _default_ to my fqdn). When I fixed this error, everything worked fine.

From MSDN:

Set Keyword: In VBA, the Set keyword is necessary to distinguish between assignment of an object and assignment of the default property of the object. Since default properties are not supported in Visual Basic .NET, the Set keyword is not needed and is no longer supported.

        def jsonFile = new File('File Path');
        JsonSlurper jsonSlurper = new JsonSlurper();
        def parseJson = jsonSlurper.parse(jsonFile)
        String json = JsonOutput.toJson(parseJson)
        def prettyJson = JsonOutput.prettyPrint(json)
        println(prettyJson)

use Contains of jquery Contains like this

if ($('.type:contains("> <")').length > 0)
{
 //do stuffs to change 
}

Make use of using the Color and Backcolor Properties to write Expressions for your query. Add the following to the expression option for the color property that you want to cater for)

Example

=iif(fields!column.value = "Approved", "Green","<other color>")

iif needs 3 values, first the relating Column, then the second is to handle the True and the third is to handle the False for the iif statement

No. It's going to be quite a big effort to port a browser environment to node.

Another approach, that I'm currently investigating for unit testing, is to create "Mock" version of jQuery that provides callbacks whenever a selector is called.

This way you could unit test your jQuery plugins without actually having a DOM. You'll still have to test in real browsers to see if your code works in the wild, but if you discover browser specific issues, you can easily "mock" those in your unit tests as well.

I'll push something to github.com/felixge once it's ready to show.

Using the constructor

BigInteger(String val)

Translates the decimal String representation of a BigInteger into a BigInteger.

Javadoc

Not the most beautiful way of doing it I guess:

git log --pretty=oneline | wc -l

This gives you a number then

git log HEAD~<The number minus one>

If istream fails to insert, it will set the fail bit.

int i = 0;
std::cin >> i; // type a and press enter
if (std::cin.fail())
{
    std::cout << "I failed, try again ..." << std::endl
    std::cin.clear(); // reset the failed state
}

You can set this up in a do-while loop to get the correct type (int in this case) propertly inserted.

This code worked for me. I use ojdbc6-11.2.0.2.jar.

java.sql.Connection con;
javax.xml.bind.Marshaller marshaller;

Clob xmlClob = con.createClob();
try {
  try (Writer xmlClobWriter = xmlClob.setCharacterStream(1)) {
    m.marshal(jaxbObject, xmlClobWriter);
  } // xmlClobWriter.close();
  try (PreparedStatement stmt = con.prepareStatement("INSERT INTO table (xml) values(?)")) {
    stmt.setClob(1, xmlClob);
    stmt.executeUpdate();
  }
} finally {
  xmlClob.free();
}

You can use a nested Array.prototype.some call. This has the benefit that it will bail at the first match instead of other solutions that will run through the full nested loop.

eg.

var arr = [1, 2, 3];
var match = [2, 4];

var hasMatch = arr.some(a => match.some(m => a === m));

According to Fixture finalization / executing teardown code, the current best practice for setup and teardown is to use yield instead of return:

import pytest

@pytest.fixture()
def resource():
    print("setup")
    yield "resource"
    print("teardown")

class TestResource:
    def test_that_depends_on_resource(self, resource):
        print("testing {}".format(resource))

Running it results in

$ py.test --capture=no pytest_yield.py
=== test session starts ===
platform darwin -- Python 2.7.10, pytest-3.0.2, py-1.4.31, pluggy-0.3.1
collected 1 items

pytest_yield.py setup
testing resource
.teardown


=== 1 passed in 0.01 seconds ===

Another way to write teardown code is by accepting a request-context object into your fixture function and calling its request.addfinalizer method with a function that performs the teardown one or multiple times:

import pytest

@pytest.fixture()
def resource(request):
    print("setup")

    def teardown():
        print("teardown")
    request.addfinalizer(teardown)
    
    return "resource"

class TestResource:
    def test_that_depends_on_resource(self, resource):
        print("testing {}".format(resource))

Here's a complete, self-contained example. First, use the following HTML:

<canvas id="example" width="200" height="60"></canvas>
<div id="status"></div>

Then put some squares on the canvas with random background colors:

var example = document.getElementById('example');
var context = example.getContext('2d');
context.fillStyle = randomColor();
context.fillRect(0, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(55, 0, 50, 50);
context.fillStyle = randomColor();
context.fillRect(110, 0, 50, 50);

And print each color on mouseover:

$('#example').mousemove(function(e) {
    var pos = findPos(this);
    var x = e.pageX - pos.x;
    var y = e.pageY - pos.y;
    var coord = "x=" + x + ", y=" + y;
    var c = this.getContext('2d');
    var p = c.getImageData(x, y, 1, 1).data; 
    var hex = "#" + ("000000" + rgbToHex(p[0], p[1], p[2])).slice(-6);
    $('#status').html(coord + "<br>" + hex);
});

The code above assumes the presence of jQuery and the following utility functions:

function findPos(obj) {
    var curleft = 0, curtop = 0;
    if (obj.offsetParent) {
        do {
            curleft += obj.offsetLeft;
            curtop += obj.offsetTop;
        } while (obj = obj.offsetParent);
        return { x: curleft, y: curtop };
    }
    return undefined;
}

function rgbToHex(r, g, b) {
    if (r > 255 || g > 255 || b > 255)
        throw "Invalid color component";
    return ((r << 16) | (g << 8) | b).toString(16);
}

function randomInt(max) {
  return Math.floor(Math.random() * max);
}

function randomColor() {
    return `rgb(${randomInt(256)}, ${randomInt(256)}, ${randomInt(256)})`
}

Skip reading the html and use curl to POST whatever form data you want to submit to the server.

You can add a tree observer to the layout. This should return the correct width and height. onCreate() is called before the layout of the child views are done. So the width and height is not calculated yet. To get the height and width, put this on the onCreate() method:

    final LinearLayout layout = (LinearLayout) findViewById(R.id.YOUR_VIEW_ID);
    ViewTreeObserver vto = layout.getViewTreeObserver(); 
    vto.addOnGlobalLayoutListener (new OnGlobalLayoutListener() { 
        @Override 
        public void onGlobalLayout() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
                    layout.getViewTreeObserver()
                            .removeOnGlobalLayoutListener(this);
                } else {
                    layout.getViewTreeObserver()
                            .removeGlobalOnLayoutListener(this);
                }
            int width  = layout.getMeasuredWidth();
            int height = layout.getMeasuredHeight(); 

        } 
    });

Here is my PowerShell method

gci env:* | sort-object name | Where-Object {$_.Name -like "MyApp*"} | Foreach {"[System.Environment]::SetEnvironmentVariable('$($_.Name)', '$($_.Value)', 'Machine')"}

What it does

1. Scoops up all environment variables
2. Filters them
3. Emits the formatted PowerShell needed to recreate them on another machine (assumes all are set at machine level)

So after running this on the source machine, simply transfer output onto the target machine and execute (elevated prompt if setting at machine level)

HTML:

<div id="id">
</div>
<div id="hiddenDiv" style="display:none;"></div>

jQuery:

$('#id').hover(function(){
    $("#hiddenDiv").css('display','block');
  },
  function(){
    $("#hiddenDiv").css('display','none');
  }
);

You can Try this ,

Here you can get the date based on the Client Timezone (Browser).

moment(new Date().getTime()).zone(new Date().toString().match(/([-\+][0-9]+)\s/)[1]).format('YYYY-MM-DD HH:mm:ss')

The regex basically gets you the offset value.

You can use default javascript cookies set method. this working perfect.

createCookieInHour: (cookieName, cookieValue, hourToExpire) => {
    let date = new Date();
    date.setTime(date.getTime()+(hourToExpire*60*60*1000));
    document.cookie = cookieName + " = " + cookieValue + "; expires = " +date.toGMTString();
},

call java scripts funtion in react method as below,

createCookieInHour('cookieName', 'cookieValue', 5);

and you can use below way to view cookies.

let cookie = document.cookie.split(';');
console.log('cookie : ', cookie);

Libpng-1.6 is more stringent about checking ICC profiles than previous versions. You can ignore the warning. To get rid of it, remove the iCCP chunk from the PNG image.

Some applications treat warnings as errors; if you are using such an application you do have to remove the chunk. You can do that with any of a variety of PNG editors such as ImageMagick's

convert in.png out.png

To remove the invalid iCCP chunk from all of the PNG files in a folder (directory), you can use mogrify from ImageMagick:

mogrify *.png

This requires that your ImageMagick was built with libpng16. You can easily check it by running:

convert -list format | grep PNG

If you'd like to find out which files need to be fixed instead of blindly processing all of them, you can run

pngcrush -n -q *.png

where the -n means don't rewrite the files and -q means suppress most of the output except for warnings. Sorry, there's no option yet in pngcrush to suppress everything but the warnings.

Binary Releases of ImageMagick are here

For Android Projects (Android Studio) navigate into res folder.

For example:

C:\{your_project_folder}\app\src\main\res\drawable-hdpi\mogrify *.png

Change your directive definition from app.module to app.directive. Apart from that everything looks fine. Btw, very rarely do you have to inject a service into a directive. If you are injecting a service ( which usually is a data source or model ) into your directive ( which is kind of part of a view ), you are creating a direct coupling between your view and model. You need to separate them out by wiring them together using a controller.

It does work fine. I am not sure what you are doing which is wrong. Here is a plunk of it working.

http://plnkr.co/edit/M8omDEjvPvBtrBHM84Am

First off, you're not dealing with a "JSON object." You're dealing with a JavaScript object. JSON is a textual notation, but if your example code works ([0].amount), you've already deserialized that notation into a JavaScript object graph. (What you've quoted isn't valid JSON at all; in JSON, the keys must be in double quotes. What you've quoted is a JavaScript object literal, which is a superset of JSON.)

Here, length of this array is 2.

No, it's 3.

So, i need to get the name (like amount or job... totally four name) and also to count how many names are there?

If you're using an environment that has full ECMAScript5 support, you can use Object.keys (spec | MDN) to get the enumerable keys for one of the objects as an array. If not (or if you just want to loop through them rather than getting an array of them), you can use for..in:

var entry;
var name;
entry = array[0];
for (name in entry) {
    // here, `name` will be "amount", "job", "month", then "year" (in no defined order)
}

Full working example:

(function() {_x000D_
  _x000D_
  var array = [_x000D_
    {_x000D_
      amount: 12185,_x000D_
      job: "GAPA",_x000D_
      month: "JANUARY",_x000D_
      year: "2010"_x000D_
    },_x000D_
    {_x000D_
      amount: 147421,_x000D_
      job: "GAPA",_x000D_
      month: "MAY",_x000D_
      year: "2010"_x000D_

Since you're dealing with raw objects, the above for..in loop is fine (unless someone has committed the sin of mucking about with Object.prototype, but let's assume not). But if the object you want the keys from may also inherit enumerable properties from its prototype, you can restrict the loop to only the object's own keys (and not the keys of its prototype) by adding a hasOwnProperty call in there:

for (name in entry) {
  if (entry.hasOwnProperty(name)) {
    display(name);
    ++count;
  }
}

Modify your query to generate the output that you want.

Try casting them to int:

select cast(bitFlag as int)

Or, if you like, use case:

select (case when bitFlag = 0 then 0 else 1 end)

I wrote a custom classloader, from which it is possible to unload individual classes without GCing the classloader. Jar Class Loader

<script>$(function(){var svg = d3.select("#chart").append("svg:svg");});</script>
<div id="chart"></div>

In other words, it's not happening because you can't query against something that doesn't exist yet-- so just do it after the page loads (here via jquery).

Btw, its recommended that you place your JS files before the close of your body tag.

If there is no such mechanism, what is a pattern/convention for such problems?

The term 'cleanup' might be more appropriate, but will use 'destructor' to match OP

Suppose you write some javascript entirely with 'function's and 'var's. Then you can use the pattern of writing all the functions code within the framework of a try/catch/finally lattice. Within finally perform the destruction code.

Instead of the C++ style of writing object classes with unspecified lifetimes, and then specifying the lifetime by arbitrary scopes and the implicit call to ~() at scope end (~() is destructor in C++), in this javascript pattern the object is the function, the scope is exactly the function scope, and the destructor is the finally block.

If you are now thinking this pattern is inherently flawed because try/catch/finally doesn't encompass asynchronous execution which is essential to javascript, then you are correct. Fortunately, since 2018 the asynchronous programming helper object Promise has had a prototype function finally added to the already existing resolve and catch prototype functions. That means that that asynchronous scopes requiring destructors can be written with a Promise object, using finally as the destructor. Furthermore you can use try/catch/finally in an async function calling Promises with or without await, but must be aware that Promises called without await will be execute asynchronously outside the scope and so handle the desctructor code in a final then.

In the following code PromiseA and PromiseB are some legacy API level promises which don't have finally function arguments specified. PromiseC DOES have a finally argument defined.

async function afunc(a,b){
    try {
        function resolveB(r){ ... }
        function catchB(e){ ... }
        function cleanupB(){ ... }
        function resolveC(r){ ... }
        function catchC(e){ ... }
        function cleanupC(){ ... }
        ...
        // PromiseA preced by await sp will finish before finally block.  
        // If no rush then safe to handle PromiseA cleanup in finally block 
        var x = await PromiseA(a);
        // PromiseB,PromiseC not preceded by await - will execute asynchronously
        // so might finish after finally block so we must provide 
        // explicit cleanup (if necessary)
        PromiseB(b).then(resolveB,catchB).then(cleanupB,cleanupB);
        PromiseC(c).then(resolveC,catchC,cleanupC);
    }
    catch(e) { ... }
    finally { /* scope destructor/cleanup code here */ }
}

I am not advocating that every object in javascript be written as a function. Instead, consider the case where you have a scope identified which really 'wants' a destructor to be called at its end of life. Formulate that scope as a function object, using the pattern's finally block (or finally function in the case of an asynchronous scope) as the destructor. It is quite like likely that formulating that functional object obviated the need for a non-function class which would otherwise have been written - no extra code was required, aligning scope and class might even be cleaner.

Note: As others have written, we should not confuse destructors and garbage collection. As it happens C++ destructors are often or mainly concerned with manual garbage collection, but not exclusively so. Javascript has no need for manual garbage collection, but asynchronous scope end-of-life is often a place for (de)registering event listeners, etc..

Even though you asked for wait() and notify() specifically, I feel that this quote is still important enough:

Josh Bloch, Effective Java 2nd Edition, Item 69: Prefer concurrency utilities to wait and notify (emphasis his):

Given the difficulty of using wait and notify correctly, you should use the higher-level concurrency utilities instead [...] using wait and notify directly is like programming in "concurrency assembly language", as compared to the higher-level language provided by java.util.concurrent. There is seldom, if ever, reason to use wait and notify in new code.

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

For me none worked. I compared my existing eclipse.ini with a new one and started removing options and testing if eclipse worked.

The only option that prevented eclipse from starting was -XX:+UseParallelGC, so I removed it and voilá!

I went with an adaptation of the @gustavohenke solution, implementing cast ObjectId in a try-catch wrapped around the original code to leverage the failure of ObjectId casting as a validation method.

Controller.prototype.show = function(id, res) {
  try {
    var _id = mongoose.Types.ObjectId.fromString(id);



    // the original code stays the same, with _id instead of id:

    this.model.findById(_id, function(err, doc) {
      if (err) {
        throw err;
      }
      if (!doc) {
        res.send(404);
      }
      return res.send(doc);
    });



  } catch (err) {
    res.json(404, err);
  }
};

I liked the solution in the earlier post.

I made a mini-class, called it class AlphabeticalHash. It also has a method called ap, which accepts one argument, a Hash, as input: ap variable. Akin to pp (pp variable)

But it will (try and) print in alphabetical list (its keys). Dunno if anyone else wants to use this, it's available as a gem, you can install it as such: gem install alphabetical_hash

For me, this is simple enough. If others need more functionality, let me know, I'll include it into the gem.

EDIT: Credit goes to Peter, who gave me the idea. :)

if you need to eliminate duplicates on specific keys, such as a mysqli id, here's a simple funciton

function search_array_compact($data,$key){
    $compact = [];
    foreach($data as $row){
        if(!in_array($row[$key],$compact)){
            $compact[] = $row;
        }
    }
    return $compact;
}

Bonus Points You can pass an array of keys and add an outer foreach, but it will be 2x slower per additional key.

You can do it with Joda DateTime API

DateTime date= new DateTime(dateObj);
date = date.plusHours(1);
dateObj = date.toDate();

In your specific case, you can set the containing a element to be:

a {
    display: block;
    text-align: center;
}

JS Bin demo.

If am not wrong

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
   //You may decide to prompt to user
   //else just kill
   Process.GetCurrentProcess().Kill();
} 

i.e we need to take multiple email addresses separated by comma, spaces or newline as below.

    var emails = EmailText.replace(","," ").replace("\n"," ").replace(" ","").split(" ");
    for(var i in emails)
        emails[i] = emails[i].replace(/(\r\n|\n|\r)/gm,"");

    emails.filter(Boolean);
    console.log(emails);

What you want is org.mockito.Mockito.CALLS_REAL_METHODS according to the docs:

/**
 * Optional <code>Answer</code> to be used with {@link Mockito#mock(Class, Answer)}
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations.
 * <p>
 * This implementation can be helpful when working with legacy code.
 * When this implementation is used, unstubbed methods will delegate to the real implementation.
 * This is a way to create a partial mock object that calls real methods by default.
 * <p>
 * As usual you are going to read <b>the partial mock warning</b>:
 * Object oriented programming is more less tackling complexity by dividing the complexity into separate, specific, SRPy objects.
 * How does partial mock fit into this paradigm? Well, it just doesn't... 
 * Partial mock usually means that the complexity has been moved to a different method on the same object.
 * In most cases, this is not the way you want to design your application.
 * <p>
 * However, there are rare cases when partial mocks come handy: 
 * dealing with code you cannot change easily (3rd party interfaces, interim refactoring of legacy code etc.)
 * However, I wouldn't use partial mocks for new, test-driven & well-designed code.
 * <p>
 * Example:
 * <pre class="code"><code class="java">
 * Foo mock = mock(Foo.class, CALLS_REAL_METHODS);
 *
 * // this calls the real implementation of Foo.getSomething()
 * value = mock.getSomething();
 *
 * when(mock.getSomething()).thenReturn(fakeValue);
 *
 * // now fakeValue is returned
 * value = mock.getSomething();
 * </code></pre>
 */

Thus your code should look like:

import org.junit.Test;
import static org.mockito.Mockito.*;
import static org.junit.Assert.*;

public class StockTest {

    public class Stock {
        private final double price;
        private final int quantity;

        Stock(double price, int quantity) {
            this.price = price;
            this.quantity = quantity;
        }

        public double getPrice() {
            return price;
        }

        public int getQuantity() {
            return quantity;
        }

        public double getValue() {
            return getPrice() * getQuantity();
        }
    }

    @Test
    public void getValueTest() {
        Stock stock = mock(Stock.class, withSettings().defaultAnswer(CALLS_REAL_METHODS));
        when(stock.getPrice()).thenReturn(100.00);
        when(stock.getQuantity()).thenReturn(200);
        double value = stock.getValue();

        assertEquals("Stock value not correct", 100.00 * 200, value, .00001);
    }
}

The call to Stock stock = mock(Stock.class); calls org.mockito.Mockito.mock(Class<T>) which looks like this:

 public static <T> T mock(Class<T> classToMock) {
    return mock(classToMock, withSettings().defaultAnswer(RETURNS_DEFAULTS));
}

The docs of the value RETURNS_DEFAULTS tell:

/**
 * The default <code>Answer</code> of every mock <b>if</b> the mock was not stubbed.
 * Typically it just returns some empty value. 
 * <p>
 * {@link Answer} can be used to define the return values of unstubbed invocations. 
 * <p>
 * This implementation first tries the global configuration. 
 * If there is no global configuration then it uses {@link ReturnsEmptyValues} (returns zeros, empty collections, nulls, etc.)
 */

Note: As pointed out in the comments by @nevf, this solution may no longer work (at least in Chrome) due to performance changes. The recommendation is to use touch-action which is also suggested by @JohnWeisz's answer.

Similar to the answer given by @Llepwryd, I used a combination of ontouchstart and ontouchmove to prevent scrolling when it is on a certain element.

Taken as-is from a project of mine:

window.blockMenuHeaderScroll = false;
$(window).on('touchstart', function(e)
{
    if ($(e.target).closest('#mobileMenuHeader').length == 1)
    {
        blockMenuHeaderScroll = true;
    }
});
$(window).on('touchend', function()
{
    blockMenuHeaderScroll = false;
});
$(window).on('touchmove', function(e)
{
    if (blockMenuHeaderScroll)
    {
        e.preventDefault();
    }
});

Essentially, what I am doing is listening on the touch start to see whether it begins on an element that is a child of another using jQuery .closest and allowing that to turn on/off the touch movement doing scrolling. The e.target refers to the element that the touch start begins with.

You want to prevent the default on the touch move event however you also need to clear your flag for this at the end of the touch event otherwise no touch scroll events will work.

This can be accomplished without jQuery however for my usage, I already had jQuery and didn't need to code something up to find whether the element has a particular parent.

Tested in Chrome on Android and an iPod Touch as of 2013-06-18

you can see the solution on http://jsfiddle.net/CBQCA/1/

OR

<table style="height:100%;width:100%; position: absolute; top: 0; bottom: 0; left: 0; right: 0;border:1px solid">
     <tr style="height: 25%;">
        <td>Region</td>
    </tr>
    <tr style="height: 75%;">
        <td>100.00%</td>
    </tr>
</table>?

I removed the font size, to show that columns are expanded. I added border:1px solid just to make sure table is expanded. you can remove it.

myList.Count is a method on the list object, it just returns the value of a field so is very fast. As it is a small method it is very likely to be inlined by the compiler (or runtime), they may then allow other optimization to be done by the compiler.

myList.Count() is calling an extension method (introduced by LINQ) that loops over all the items in an IEnumerable, so should be a lot slower.

However (In the Microsoft implementation) the Count extension method has a “special case” for Lists that allows it to use the list’s Count property, this means the Count() method is only a little slower than the Count property.

It is unlikely you will be able to tell the difference in speed in most applications.

So if you know you are dealing with a List use the Count property, otherwise if you have a "unknown" IEnumerabl, use the Count() method and let it optimise for you.

var img = new Image(1,1); // width, height values are optional params

if you need to do something before submitting data, you could use form's onsubmit.

<form method=post onsubmit="return doSomething()">
  <input type=text name=text1>
  <input type=submit>
</form>

Regarding the difference between an object and an instance, I do not think there is any consensus.

It looks to me like people change it pretty much interchangeably, in papers, blog posts, books or conversations.

As for me, the way I see it is, an object is a generic and alive entity in the memory, specified by the language it is used in. Just like the Object class in Java. We do not much care its type, or anything else associated with it, whether it is managed by a container or not.

An instance is an object but associated with a type, as in this method accepts Foo instances, or you can not put Animal instances in an instance of a List of Vehicles.

objects for example have locks associated with them, not instances, whereas instances have methods. objects are garbage collected, not instances.

But as I said, this is only how I see it, and I do not think there is any organisation we can refer to for a standard definition between them and everyone will pretty much have their slightly different understanding / definitions (of course within limits).

SELECT group,subGroup,COUNT(*) FROM tablename GROUP BY group,subgroup

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

As mentioned in "Polling must die: triggering Jenkins builds from a git hook", you can notify Jenkins of a new commit:

With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>

This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)

This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.

As mentioned here, make sure to use the right address for your Jenkins server:

since we're running Jenkins as standalone Webserver on port 8080 the URL should have been without the /jenkins, like this:

http://jenkins:8080/git/notifyCommit?url=git@gitserver:tools/common.git

To reinforce that last point, ptha adds in the comments:

It may be obvious, but I had issues with:

curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>. 

The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our case ssh://, and it didn't work.

You can also use a simple post-receive hook like in "Push based builds using Jenkins and GIT"

#!/bin/bash
/usr/bin/curl --user USERNAME:PASS -s \

http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx

Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (1qaz2wsx in this example).

However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn't depend on authentication or a specific project.

I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.

Basically, your build script can:

• put a 'build' notes (see git notes) on the first call
• on the subsequent calls, grab the list of commits between HEAD of your branch candidate for build and the commit referenced by the git notes 'build' (git show refs/notes/build): git diff --name-only SHA_build HEAD.
• your script can parse that list and decide if it needs to go on with the build.
• in any case, create/move your git notes 'build' to HEAD.

May 2016: cwhsu points out in the comments the following possible url:

you could just use curl --user USER:PWD http://JENKINS_SERVER/job/JOB_NAME/build?token=YOUR_TOKEN if you set trigger config in your item

June 2016, polaretto points out in the comments:

I wanted to add that with just a little of shell scripting you can avoid manual url configuration, especially if you have many repositories under a common directory.
For example I used these parameter expansions to get the repo name

repository=${PWD%/hooks}; 
repository=${repository##*/} 

and then use it like:

curl $JENKINS_URL/git/notifyCommit?url=$GIT_URL/$repository

For first Date

$_firstDate = date("m-d-Y", strtotime($_yourDateString));

For New Date

$_newDate = date("Y-m-d",strtotime($_yourDateString));

A simple example in Groovy for your reference:

def outer() {
    def x = 1
    return { -> println(x)} // inner
}
def innerObj = outer()
innerObj() // prints 1

You can do:

flask.jsonify(**data)

or

flask.jsonify(id=str(album.id), title=album.title)

<div id='printarea'>
    <p>This is a sample text for printing purpose.</p> 
</div>
<input type='button' id='btn' value='Print' onlick="printDiv()">
<p>Do not print.</p>

function printDiv(){
        var printContents = document.getElementById("printarea").innerHTML;
        var originalContents = document.body.innerHTML;
        document.body.innerHTML = printContents;
        window.print();
        document.body.innerHTML = originalContents;
}

This Above function should be load on same page.

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

Here's a no framework code, only pure js :

document.querySelectorAll('img.svg').forEach(function(element) {
            var imgID = element.getAttribute('id')
            var imgClass = element.getAttribute('class')
            var imgURL = element.getAttribute('src')

            xhr = new XMLHttpRequest()
            xhr.onreadystatechange = function() {
                if(xhr.readyState == 4 && xhr.status == 200) {
                    var svg = xhr.responseXML.getElementsByTagName('svg')[0];

                    if(imgID != null) {
                         svg.setAttribute('id', imgID);
                    }

                    if(imgClass != null) {
                         svg.setAttribute('class', imgClass + ' replaced-svg');
                    }

                    svg.removeAttribute('xmlns:a')

                    if(!svg.hasAttribute('viewBox') && svg.hasAttribute('height') && svg.hasAttribute('width')) {
                        svg.setAttribute('viewBox', '0 0 ' + svg.getAttribute('height') + ' ' + svg.getAttribute('width'))
                    }
                    element.parentElement.replaceChild(svg, element)
                }
            }
            xhr.open('GET', imgURL, true)
            xhr.send(null)
        })

If you assume that there can be duplicate values the only way to do this is to put the values in lists, sort them and compare the lists viz:

List<String> values1 = new ArrayList<String>(map1.values());
List<String> values2 = new ArrayList<String>(map2.values());
Collections.sort(values1);
Collections.sort(values2);
boolean mapsHaveEqualValues = values1.equals(values2);

If values cannot contain duplicate values then you can either do the above without the sort using sets.

Editor's Note: All functions in JavaScript are closures as explained in this post. However we are only interested in identifying a subset of these functions which are interesting from a theoretical point of view. Henceforth any reference to the word closure will refer to this subset of functions unless otherwise stated.

A simple explanation for closures:

1. Take a function. Let's call it F.
2. List all the variables of F.
3. The variables may be of two types:
   1. Local variables (bound variables)
   2. Non-local variables (free variables)
4. If F has no free variables then it cannot be a closure.
5. If F has any free variables (which are defined in a parent scope of F) then:
   1. There must be only one parent scope of F to which a free variable is bound.
   2. If F is referenced from outside that parent scope, then it becomes a closure for that free variable.
   3. That free variable is called an upvalue of the closure F.

Now let's use this to figure out who uses closures and who doesn't (for the sake of explanation I have named the functions):

Case 1: Your Friend's Program

for (var i = 0; i < 10; i++) {
    (function f() {
        var i2 = i;
        setTimeout(function g() {
            console.log(i2);
        }, 1000);
    })();
}

In the above program there are two functions: f and g. Let's see if they are closures:

For f:

1. List the variables:
   1. i2 is a local variable.
   2. i is a free variable.
   3. setTimeout is a free variable.
   4. g is a local variable.
   5. console is a free variable.
2. Find the parent scope to which each free variable is bound:
   1. i is bound to the global scope.
   2. setTimeout is bound to the global scope.
   3. console is bound to the global scope.
3. In which scope is the function referenced? The global scope.
   1. Hence i is not closed over by f.
   2. Hence setTimeout is not closed over by f.
   3. Hence console is not closed over by f.

Thus the function f is not a closure.

For g:

1. List the variables:
   1. console is a free variable.
   2. i2 is a free variable.
2. Find the parent scope to which each free variable is bound:
   1. console is bound to the global scope.
   2. i2 is bound to the scope of f.
3. In which scope is the function referenced? The scope of setTimeout.
   1. Hence console is not closed over by g.
   2. Hence i2 is closed over by g.

Thus the function g is a closure for the free variable i2 (which is an upvalue for g) when it's referenced from within setTimeout.

Bad for you: Your friend is using a closure. The inner function is a closure.

Case 2: Your Program

for (var i = 0; i < 10; i++) {
    setTimeout((function f(i2) {
        return function g() {
            console.log(i2);
        };
    })(i), 1000);
}

In the above program there are two functions: f and g. Let's see if they are closures:

For f:

1. List the variables:
   1. i2 is a local variable.
   2. g is a local variable.
   3. console is a free variable.
2. Find the parent scope to which each free variable is bound:
   1. console is bound to the global scope.
3. In which scope is the function referenced? The global scope.
   1. Hence console is not closed over by f.

Thus the function f is not a closure.

For g:

1. List the variables:
   1. console is a free variable.
   2. i2 is a free variable.
2. Find the parent scope to which each free variable is bound:
   1. console is bound to the global scope.
   2. i2 is bound to the scope of f.
3. In which scope is the function referenced? The scope of setTimeout.
   1. Hence console is not closed over by g.
   2. Hence i2 is closed over by g.

Thus the function g is a closure for the free variable i2 (which is an upvalue for g) when it's referenced from within setTimeout.

Good for you: You are using a closure. The inner function is a closure.

So both you and your friend are using closures. Stop arguing. I hope I cleared the concept of closures and how to identify them for the both of you.

Edit: A simple explanation as to why are all functions closures (credits @Peter):

First let's consider the following program (it's the control):

lexicalScope();_x000D_
_x000D_
function lexicalScope() {_x000D_
    var message = "This is the control. You should be able to see this message being alerted.";_x000D_
_x000D_
    regularFunction();_x000D_
_x000D_
    function regularFunction() {_x000D_
        alert(eval("message"));_x000D_
    }_x000D_
}

1. We know that both lexicalScope and regularFunction aren't closures from the above definition.
2. When we execute the program we expect message to be alerted because regularFunction is not a closure (i.e. it has access to all the variables in its parent scope - including message).
3. When we execute the program we observe that message is indeed alerted.

Next let's consider the following program (it's the alternative):

var closureFunction = lexicalScope();_x000D_
_x000D_
closureFunction();_x000D_
_x000D_
function lexicalScope() {_x000D_
    var message = "This is the alternative. If you see this message being alerted then in means that every function in JavaScript is a closure.";_x000D_
_x000D_
    return function closureFunction() {_x000D_
        alert(eval("message"));_x000D_
    };_x000D_
}

1. We know that only closureFunction is a closure from the above definition.
2. When we execute the program we expect message not to be alerted because closureFunction is a closure (i.e. it only has access to all its non-local variables at the time the function is created (see this answer) - this does not include message).
3. When we execute the program we observe that message is actually being alerted.

What do we infer from this?

1. JavaScript interpreters do not treat closures differently from the way they treat other functions.
2. Every function carries its scope chain along with it. Closures don't have a separate referencing environment.
3. A closure is just like every other function. We just call them closures when they are referenced in a scope outside the scope to which they belong because this is an interesting case.

IE 8 doesn't have indexOf function, so I used jQuery inArray instead.

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [$.inArray(string, array) == -1];
    }
});

varchar(10) will store 10 characters, which may be more than 10 bytes. In indexes, it will allocate the maximium length of the field - so if you are using UTF8-mb4, it will allocate 40 bytes for the 10 character field.

If you can't access the iFrame class then add below css to wrapper div.

<div style="display: flex; justify-content: center;">
    <iframe></iframe>
</div>

Your system is missing the mysqlnd driver!

If you are able to install new packages on your (Debian/Ubuntu-based) server, install the driver:

sudo apt-get install php5-mysqlnd

and then restart your web server:

sudo /etc/init.d/apache2 restart

Your concatenation syntax is correct.

Most likely the callback function isn't even being called. You can test that by putting an alert(), console.log() or debugger line in that function.

If it isn't being called, most likely there's an AJAX error. Look at chaining a .fail() handler after $.post() to find out what the error is, e.g.:

$.post('ajaxskeleton.php', {
    red: text       
}, function(){
    $('#part' + number).html(text);
}).fail(function(jqXHR, textStatus, errorThrown) {
    console.log(arguments);
});

select group_id, 
       listagg(name, ',') within group (order by name) as names
       over (partition by group_id)   
from demotable
group by group_id 

For me this was because i stopped using the -aot flag whilst trying to make the compile time faster.

 ng serve -aot

Swift 3 | UIDeviceOrientationDidChange Notification Observed Too Often

The following code prints "deviceDidRotate" every time your device changes orientation in 3D space - regardless of a change from portrait to landscape orientation. For example, if you hold your phone in portrait orientation and tilt it forward and backward - deviceDidRotate() is called repeatedly.

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(
        self, 
        selector:  #selector(deviceDidRotate), 
        name: .UIDeviceOrientationDidChange, 
        object: nil
    )
}

func deviceDidRotate() {
    print("deviceDidRotate")
}

To work around this you could hold the previous device orientation and check for a change in deviceDidRotate().

var previousDeviceOrientation: UIDeviceOrientation = UIDevice.current.orientation

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(
        self, 
        selector:  #selector(deviceDidRotate), 
        name: .UIDeviceOrientationDidChange, 
        object: nil
    )
}

func deviceDidRotate() {
    if UIDevice.current.orientation == previousDeviceOrientation { return }
    previousDeviceOrientation = UIDevice.current.orientation
    print("deviceDidRotate")
}

Or you can use a different notification that only gets called when the device changes from landscape to portrait. In this case you'd want to use the UIApplicationDidChangeStatusBarOrientation notification.

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(
        self, 
        selector:  #selector(deviceDidRotate), 
        name: .UIApplicationDidChangeStatusBarOrientation, 
        object: nil
    )
}

func deviceDidRotate() {
    print("deviceDidRotate")
}

You can use Hash#reject to remove empty key/value pairs from a ruby Hash.

# Remove empty strings
{ a: 'first', b: '', c: 'third' }.reject { |key,value| value.empty? } 
#=> {:a=>"first", :c=>"third"}

# Remove nil
{a: 'first', b: nil, c: 'third'}.reject { |k,v| v.nil? } 
# => {:a=>"first", :c=>"third"}

# Remove nil & empty strings
{a: '', b: nil, c: 'third'}.reject { |k,v| v.nil? || v.empty? } 
# => {:c=>"third"}

echo (""); is a php code, and <prev> tries to be HTML, but isn't.

$('<img src="'+ imgPath +'">').load(function() {
  $(this).width(some).height(some).appendTo('#some_target');
});

If you want to do for several images then:

function loadImage(path, width, height, target) {
    $('<img src="'+ path +'">').load(function() {
      $(this).width(width).height(height).appendTo(target);
    });
}

Use:

loadImage(imgPath, 800, 800, '#some_target');

This would require knowledge of a backend website language.

Fortunately, Python's Flask Library is a suitable backend language for the project at hand.

Check out this answer from another thread.

A library and demo with the complete source code for scrolling toolbars or any type of header can be downloaded here:

https://github.com/JohannBlake/JBHeaderScroll

Headers can be Toolbars, LinearLayouts, RelativeLayouts, or whatever type of view you use to create a header.

The scrollable area can be any type of scroll content including ListView, ScrollView, WebView, RecyclerView, RelativeLayout, LinearLayout or whatever you want.

There's even support for nested headers.

It is indeed a complex undertaking to synchronize headers (toolbars) and scrollable content the way it's done in Google Newsstand.

This library doesn't require implementing any kind of onScrollListener.

The solutions listed above by others are only half baked solutions that don't take into consideration that the top edge of the scrollable content area beneath the toolbar has to initially be aligned to the bottom edge of the toolbar and then during scrolling the content area needs to be repositioned and possibly resized. The JBHeaderScroll handles all these issues.

In R Language (version 3.0+) You can apply filter to get unique out of a list-

data.list <- data.list %>% unique

or couple it with other operation as well

data.list.rollnumbers <- data.list %>% pull(RollNumber) %>% unique

unique doesn't require dplyr.

One .Net build with x86/x64 Dependencies

While all other answers give you a solution to make different Builds according to the platform, I give you an option to only have the "AnyCPU" configuration and make a build that works with your x86 and x64 dlls.

You have to write some plumbing code for this.

Resolution of correct x86/x64-dlls at runtime

Steps:

1. Use AnyCPU in csproj
2. Decide if you only reference the x86 or the x64 dlls in your csprojs. Adapt the UnitTests settings to the architecture settings you have chosen. It's important for debugging/running the tests inside VisualStudio.
3. On Reference-Properties set Copy Local & Specific Version to false
4. Get rid of the architecture warnings by adding this line to the first PropertyGroup in all of your csproj files where you reference x86/x64: <ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>None</ResolveAssemblyWarnOrErrorOnTargetArchitectureMismatch>

5. Add this postbuild script to your startup project, use and modify the paths of this script sp that it copies all your x86/x64 dlls in corresponding subfolders of your build bin\x86\ bin\x64\

   xcopy /E /H /R /Y /I /D $(SolutionDir)\YourPathToX86Dlls $(TargetDir)\x86 xcopy /E /H /R /Y /I /D $(SolutionDir)\YourPathToX64Dlls $(TargetDir)\x64

   --> When you would start application now, you get an exception that the assembly could not be found.

6. Register the AssemblyResolve event right at the beginning of your application entry point

   AppDomain.CurrentDomain.AssemblyResolve += TryResolveArchitectureDependency;
   

   withthis method:

   /// <summary>
   /// Event Handler for AppDomain.CurrentDomain.AssemblyResolve
   /// </summary>
   /// <param name="sender">The app domain</param>
   /// <param name="resolveEventArgs">The resolve event args</param>
   /// <returns>The architecture dependent assembly</returns>
   public static Assembly TryResolveArchitectureDependency(object sender, ResolveEventArgs resolveEventArgs)
   {
       var dllName = resolveEventArgs.Name.Substring(0, resolveEventArgs.Name.IndexOf(","));
   
       var anyCpuAssemblyPath = $".\\{dllName}.dll";
   
       var architectureName = System.Environment.Is64BitProcess ? "x64" : "x86";
   
       var assemblyPath = $".\\{architectureName}\\{dllName}.dll";
   
       if (File.Exists(assemblyPath))
       {
           return Assembly.LoadFrom(assemblyPath);
       }
   
       return null;
   }
   

7. If you have unit tests make a TestClass with a Method that has an AssemblyInitializeAttribute and also register the above TryResolveArchitectureDependency-Handler there. (This won't be executed sometimes if you run single tests inside visual studio, the references will be resolved not from the UnitTest bin. Therefore the decision in step 2 is important.)

Benefits:

• One Installation/Build for both platforms

Drawbacks: - No errors at compile time when x86/x64 dlls do not match. - You should still run test in both modes!

Optionally create a second executable that is exclusive for x64 architecture with Corflags.exe in postbuild script

Other Variants to try out: - You don't need the AssemblyResolve event handler if you assure that the right dlls are copied to your binary folder at start (Evaluate Process architecture -> move corresponding dlls from x64/x86 to bin folder and back.) - In Installer evaluate architecture and delete binaries for wrong architecture and move the right ones to the bin folder.

This works for me: redis-cli KEYS \* | xargs --max-procs=16 -L 100 redis-cli DEL

It list all Keys in redis, then pass using xargs to redis-cli DEL, using max 100 Keys per command, but running 16 command at time, very fast and useful when there is not FLUSHDB or FLUSHALL due to security reasons, for example when using Redis from Bitnami in Docker or Kubernetes. Also, it doesn't require any additional programming language and it just one line.

You need to create an API : Your js functions execute AJAX requests on your web service

  var mult = function(arg1, arg2)
    $.ajax({
      url: "webservice.php?action=mult&arg1="+arg1+"&arg2="+arg2
    }).done(function(data) {
      console.log(data);
    });
  }

on the php side, you'll have to check the action parameter in order to execute the propre function (basically a switch statement on the $_GET["action"] variable)

Executing programs through the shell means that all user input passed to the program is interpreted according to the syntax and semantic rules of the invoked shell. At best, this only causes inconvenience to the user, because the user has to obey these rules. For instance, paths containing special shell characters like quotation marks or blanks must be escaped. At worst, it causes security leaks, because the user can execute arbitrary programs.

shell=True is sometimes convenient to make use of specific shell features like word splitting or parameter expansion. However, if such a feature is required, make use of other modules are given to you (e.g. os.path.expandvars() for parameter expansion or shlex for word splitting). This means more work, but avoids other problems.

In short: Avoid shell=True by all means.

To get an object from a xib file programatically you can use: [[NSBundle mainBundle] loadNibNamed:@"MyXibName" owner:self options:nil] which returns an array of the top level objects in the xib.

So, you could do something like this:

UIView *rootView = [[[NSBundle mainBundle] loadNibNamed:@"MyRootView" owner:self options:nil] objectAtIndex:0];
UIView *containerView = [[[NSBundle mainBundle] loadNibNamed:@"MyContainerView" owner:self options:nil] lastObject];
[rootView addSubview:containerView];
[self.view addSubview:rootView];

Google Apps Script is javascript, you can use all the string methods...

var grade = itemResponse.getResponse();
if(grade.indexOf("9th")>-1){do something }

You can find doc on many sites, this one for example.

To answer TJJ: But is it also possible to do this without copying the whole file? So, just to somehow create an additional vmdk-metafile, that references the raw dd-image.

Yes, it's possible. Here's how to use a flat disk image in VirtualBox:

First you create an image with dd in the usual way:

dd bs=512 count=60000 if=/dev/zero of=usbdrv.img

Then you can create a file for VirtualBox that references this image:

VBoxManage internalcommands createrawvmdk -filename "usbdrv.vmdk" -rawdisk "usbdrv.img"

You can use this image in VirtualBox as is, but depending on the guest OS it might not be visible immediately. For example, I experimented on using this method with a Windows guest OS and I had to do the following to give it a drive letter:

• Go to the Control Panel.
• Go to Administrative Tools.
• Go to Computer Management.
• Go to Storage\Disk Management in the left side panel.
• You'll see your disk here. Create a partition on it and format it. Use FAT for small volumes, FAT32 or NTFS for large volumes.

You might want to access your files on Linux. First dismount it from the guest OS to be sure and remove it from the virtual machine. Now we need to create a virtual device that references the partition.

sfdisk -d usbdrv.img

usbdrv.img1 : start=          63, size=       48132, type=4

Take note of the start position of the partition: 63. In the command below I used loop4 because it was the first available loop device in my case.

sudo losetup -o $((63*512)) loop4 usbdrv.img
mkdir usbdrv
sudo mount /dev/loop4 usbdrv

Most JVMs will kick off a GC (depending on the -XX:DiableExplicitGC and -XX:+ExplicitGCInvokesConcurrent switch). But the specification is just less well defined in order to allow better implementations later on.

The spec needs clarification: Bug #6668279: (spec) System.gc() should indicate that we don't recommend use and don't guarantee behaviour

Internally the gc method is used by RMI and NIO, and they require synchronous execution, which: this is currently in discussion:

Bug #5025281: Allow System.gc() to trigger concurrent (not stop-the-world) full collections

tl;dr: git diff <local branch> <remote branch>

When using git on the shell, I like to first orient myself by looking around. Here's a command to show all branches

$ git branch -a  # (or git branch --all) 
* my-branch
  master
  remotes/origin/some-branch
  remotes/origin/HEAD -> origin/master
  remotes/origin/my-branch
  remotes/origin/some-other-branch
  remotes/origin/master

Here I have two local branches (my-branch and master) and 4 remote (some-branch, some-other-branch, master, and my-branch).

Also, the asterisk next to my-branch signals the fact that I'm currently in that branch (you would also know that by using the command git status that would output: On branch my-branch.).

Note: the remote branches in the git bash shell are shown in red while the local ones are shown in green.

If you just want to show remote branches:

$ git branch -r # (or git branch --remotes)
  origin/some-branch
  origin/HEAD -> origin/master
  origin/my-branch
  origin/some-other-branch
  origin/master

To show just local branches you might be tempted to use git branch -l but that's a completely different command. To show local branches use git branch with no options

$ git branch
* my-branch 
  master

To complete a review of the basic branch options there's the --list that contrary to what you might expect is there to allow filtering. Use it with a pattern like this:

$ git branch --list 'my*'
* my-branch

You can also combine --list with the options -a and -r but make sure to adapt your pattern accordingly (remember: remote branches start with "remotes"). Example:

# this will show all branches (local & remote) that start with my
$ git branch --list 'my*' -a
* my-branch

# better: the pattern includes the remote
$ git branch --list '*my*' -a
* my-branch
  remotes/origin/my-branch

Docs: https://git-scm.com/docs/git-branch

Now you can compare any two branches from all the available ones (you can also compare two locals or two remotes).

Here I'm comparing the local with the remote my-branch, they're synchronized so I don't get any output:

$ git diff my-branch remotes/origin/my-branch

Note: you have to give the full names of the branches with no quotation marks.

I can also compare the local my-branch to the remote master. Here I get some output because the remote my-branch hasn't been merged into the master branch.

$ git diff my-branch remotes/origin/master

I think it would make more sense to use "Find" function in Excel instead of For Each loop. It works much much faster and it's designed for such actions. Try this:

 Sub FindSomeCells(strSearchQuery As String)   

    Set SearchRange = Worksheets("Sheet1").Range("A1:A100")
    FindWhat = strSearchQuery
    Set FoundCells = FindAll(SearchRange:=SearchRange, _

That subroutine searches for some string and returns a collections of cells fullfilling your search criteria. Then you can do whatever you want with the cells in that collection. Forgot to add the FindAll function definition:

Function FindAll(SearchRange As Range, _
                FindWhat As Variant, _
               Optional LookIn As XlFindLookIn = xlValues, _

                Optional EndsWith As String = vbNullString, _
                Optional BeginEndCompare As VbCompareMethod = vbTextCompare) As Range

' FindAll
' This searches the range specified by SearchRange and returns a Range object
' that contains all the cells in which FindWhat was found. The search parameters to
' this function have the same meaning and effect as they do with the
' Range.Find method. If the value was not found, the function return Nothing. If
' BeginsWith is not an empty string, only those cells that begin with BeginWith
' are included in the result. If EndsWith is not an empty string, only those cells
' that end with EndsWith are included in the result. Note that if a cell contains
' a single word that matches either BeginsWith or EndsWith, it is included in the
' result.  If BeginsWith or EndsWith is not an empty string, the LookAt parameter
' is automatically changed to xlPart. The tests for BeginsWith and EndsWith may be
' case-sensitive by setting BeginEndCompare to vbBinaryCompare. For case-insensitive
' comparisons, set BeginEndCompare to vbTextCompare. If this parameter is omitted,
' it defaults to vbTextCompare. The comparisons for BeginsWith and EndsWith are
' in an OR relationship. That is, if both BeginsWith and EndsWith are provided,
' a match if found if the text begins with BeginsWith OR the text ends with EndsWith.

select controls are still clickable even on readonly attrib

if you want to still disable the control but you want its value posted. You might consider creating a hidden field. with the same value as your control.

then create a jquery, on select change

$('#your_select_id').change(function () {
    $('#your_hidden_selectid').val($('#your_select_id').val());
});

I'll assume that you're asking how to push a dependency out to a "well-known repository," and not simply asking how to update your POM.

If yes, then this is what you want to read.

And for anyone looking to set up an internal repository server, look here (half of the problem with using Maven 2 is finding the docs)

There is also a great ncdu utility - it can show directory size with detailed info about subfolders and files.

Installation

Ubuntu:

$ sudo apt-get install ncdu

Usage

Just type ncdu [path] in the command line. After a few seconds for analyzing the path, you will see something like this:

$ ncdu 1.11 ~ Use the arrow keys to navigate, press ? for help

Delete the currently highlighted element with d, exit with CTRL + c

As per PEP-20 by Tim Peters, "Explicit is better than implicit" and "Readability counts". If all you need from the os module is under os.path, import os.path would be more explicit and let others know what you really care about.

Likewise, PEP-20 also says "Simple is better than complex", so if you also need stuff that resides under the more-general os umbrella, import os would be preferred.

check your image cmd using the command docker inspect image_name . The output might be like this:

"Cmd": [
    "/bin/bash",
    "-c",
    "#(nop) ",
    "CMD [\"/bin/bash\"]"
],

So use the command docker exec -it container_id /bin/bash. If your cmd output is different like this:

"Cmd": [
    "/bin/sh",
    "-c",
    "#(nop) ",
    "CMD [\"/bin/sh\"]"
],

Use /bin/sh instead of /bin/bash in the command above.

Unfortunately, the meaning of things like ( and \( are swapped between Emacs style regular expressions and most other styles. So if you try to escape these you may be doing the opposite of what you want.

So you really have to know what style you are trying to quote.

Use $n (where n is a digit) to refer to captured subsequences in replaceFirst(...). I'm assuming you wanted to replace the first group with the literal string "number" and the second group with the value of the first group.

Pattern p = Pattern.compile("(\\d)(.*)(\\d)");
String input = "6 example input 4";
Matcher m = p.matcher(input);
if (m.find()) {
    // replace first number with "number" and second number with the first
    String output = m.replaceFirst("number $3$1");  // number 46
}

Consider (\D+) for the second group instead of (.*). * is a greedy matcher, and will at first consume the last digit. The matcher will then have to backtrack when it realizes the final (\d) has nothing to match, before it can match to the final digit.

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

I vote for the dictionary.

I find that if I make a function that returns anything more than 2-3 variables I'll fold them up in a dictionary. Otherwise I tend to forget the order and content of what I'm returning.

Also, introducing a 'special' structure makes your code more difficult to follow. (Someone else will have to search through the code to find out what it is)

If your concerned about type look up, use descriptive dictionary keys, for example, 'x-values list'.

def g(x):
  y0 = x + 1
  y1 = x * 3
  y2 = y0 ** y3
  return {'y0':y0, 'y1':y1 ,'y2':y2 }

That's about it. There is no magic built-in function...

sub uniq {
    return keys %{{ map { $_ => 1 } @_ }};
}
my @my_array = ("a","a","b","b","c");
#print join(" ", @my_array), "\n";
my $a = join(" ", uniq(@my_array));
my @b = split(/ /,$a);
my $count = $#b;

The .egg file is a distribution format for Python packages. It’s just an alternative to a source code distribution or Windows exe. But note that for pure Python, the .egg file is completely cross-platform.

The .egg file itself is essentially a .zip file. If you change the extension to “zip”, you can see that it will have folders inside the archive.

Also, if you have an .egg file, you can install it as a package using easy_install

Example: To create an .egg file for a directory say mymath which itself may have several python scripts, do the following step:

# setup.py
from setuptools import setup, find_packages
setup(
    name = "mymath",
    version = "0.1",
    packages = find_packages()
    )

Then, from the terminal do:

 $ python setup.py bdist_egg

This will generate lot of outputs, but when it’s completed you’ll see that you have three new folders: build, dist, and mymath.egg-info. The only folder that we care about is the dist folder where you'll find your .egg file, mymath-0.1-py3.5.egg with your default python (installation) version number(mine here: 3.5)

This is my first ever post & I'm very inexperienced so please go easy on me, but I feel I've got a valid contribution that may be helpful to someone...

Sometimes you need a very big time window between repeat clicks (eg a mailto link where it takes a couple of secs for the email app to open and you don't want it re-triggered), yet you don't want to slow the user down elsewhere. My solution is to use class names for the links depending on event type, while retaining double-click functionality elsewhere...

var controlspeed = 0;

$(document).on('click','a',function (event) {
    eventtype = this.className;
    controlspeed ++;
    if (eventtype == "eg-class01") {
        speedlimit = 3000;
    } else if (eventtype == "eg-class02") { 
        speedlimit = 500; 
    } else { 
        speedlimit = 0; 
    } 
    setTimeout(function() {
        controlspeed = 0;
    },speedlimit);
    if (controlspeed > 1) {
        event.preventDefault();
        return;
    } else {

        (usual onclick code goes here)

    }
});

Division of two numbers using bitwise operators.

#include <stdio.h>

int remainder, divisor;

int division(int tempdividend, int tempdivisor) {
    int quotient = 1;

    if (tempdivisor == tempdividend) {
        remainder = 0;
        return 1;
    } else if (tempdividend < tempdivisor) {
        remainder = tempdividend;
        return 0;
    }   

    do{

        tempdivisor = tempdivisor << 1;
        quotient = quotient << 1;

     } while (tempdivisor <= tempdividend);


     /* Call division recursively */
    quotient = quotient + division(tempdividend - tempdivisor, divisor);

    return quotient;
} 


int main() {
    int dividend;

    printf ("\nEnter the Dividend: ");
    scanf("%d", &dividend);
    printf("\nEnter the Divisor: ");
    scanf("%d", &divisor);   

    printf("\n%d / %d: quotient = %d", dividend, divisor, division(dividend, divisor));
    printf("\n%d / %d: remainder = %d", dividend, divisor, remainder);
    getch();
}

There is now (as of v1.10.7) a fourth way to instantiate mocks, which is using a JUnit4 rule called MockitoRule.

@RunWith(JUnit4.class)   // or a different runner of your choice
public class YourTest
  @Rule public MockitoRule rule = MockitoJUnit.rule();
  @Mock public YourMock yourMock;

  @Test public void yourTestMethod() { /* ... */ }
}

JUnit looks for subclasses of TestRule annotated with @Rule, and uses them to wrap the test Statements that the Runner provides. The upshot of this is that you can extract @Before methods, @After methods, and even try...catch wrappers into rules. You can even interact with these from within your test, the way that ExpectedException does.

MockitoRule behaves almost exactly like MockitoJUnitRunner, except that you can use any other runner, such as Parameterized (which allows your test constructors to take arguments so your tests can be run multiple times), or Robolectric's test runner (so its classloader can provide Java replacements for Android native classes). This makes it strictly more flexible to use in recent JUnit and Mockito versions.

In summary:

• Mockito.mock(): Direct invocation with no annotation support or usage validation.
• MockitoAnnotations.initMocks(this): Annotation support, no usage validation.
• MockitoJUnitRunner: Annotation support and usage validation, but you must use that runner.
• MockitoRule: Annotation support and usage validation with any JUnit runner.

Last night at 2am I closed my Eclipse (Juno) just fine. This morning I open it up and I get nothing but "Not Responding" on my 64bit Windows 7 machine.

I looked in [workspace]\.metadata\.log and it showed an error with Invalid property category path: ValidationPropertiesPage

I cuss it out pretty good and then show it who's the boss :

1. delete [workspace]\.metadata folder
2. delete [workspace]\[project]\.settings
3. Open up Eclipse to the same workspace as before, re-import your project.

Which brings me to another topic... Eclipse -> import -> Android -> Existing Android code into workspace... seems to be broken once again. But that's a different topic.

I use XAMPP and had the same error. I used Paul Gobée solution above and it worked for me. I navigated to C:\xampp\mysql\bin\mysqld-debug.exe and upon starting the .exe my Windows Firewall popped up asking for permission. Once I allowed it, it worked fine. I would have commented under his post but I do not have that much rep yet... sry! Just wanted to let everyone know this worked for me as well.

General case, not just for value types:

static class ExtensionsThatWillAppearOnEverything
{
    public static T IfDefaultGiveMe<T>(this T value, T alternate)
    {
        if (value.Equals(default(T))) return alternate;
        return value;
    }
}

var result = query.FirstOrDefault().IfDefaultGiveMe(otherDefaultValue);

Again, this can't really tell if there was anything in your sequence, or if the first value was the default.

If you care about this, you could do something like

static class ExtensionsThatWillAppearOnIEnumerables
{
    public static T FirstOr<T>(this IEnumerable<T> source, T alternate)
    {
        foreach(T t in source)
            return t;
        return alternate;
    }
}

and use as

var result = query.FirstOr(otherDefaultValue);

although as Mr. Steak points out this could be done just as well by .DefaultIfEmpty(...).First().

When doing;

a_file = open('E:\Python Win7-64-AMD 3.3\Test', encoding='utf-8')

...you're trying to open a directory as a file, which may (and on most non UNIX file systems will) fail.

Your other example though;

a_file = open('E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

should work well if you just have the permission on a.txt. You may want to use a raw (r-prefixed) string though, to make sure your path does not contain any escape characters like \n that will be translated to special characters.

a_file = open(r'E:\Python Win7-64-AMD 3.3\Test\a.txt', encoding='utf-8')

In ASP.NET Core 2 Web API, using Swashbuckle.AspNetCore package 2.1.0, implement a IDocumentFilter:

SwaggerSecurityRequirementsDocumentFilter.cs

using System.Collections.Generic;
using Swashbuckle.AspNetCore.Swagger;
using Swashbuckle.AspNetCore.SwaggerGen;

namespace api.infrastructure.filters
{
    public class SwaggerSecurityRequirementsDocumentFilter : IDocumentFilter
    {
        public void Apply(SwaggerDocument document, DocumentFilterContext context)
        {
            document.Security = new List<IDictionary<string, IEnumerable<string>>>()
            {
                new Dictionary<string, IEnumerable<string>>()
                {
                    { "Bearer", new string[]{ } },
                    { "Basic", new string[]{ } },
                }
            };
        }
    }
}

In Startup.cs, configure a security definition and register the custom filter:

public void ConfigureServices(IServiceCollection services)
{
    services.AddSwaggerGen(c =>
    {
        // c.SwaggerDoc(.....

        c.AddSecurityDefinition("Bearer", new ApiKeyScheme()
        {
            Description = "Authorization header using the Bearer scheme",
            Name = "Authorization",
            In = "header"
        });

        c.DocumentFilter<SwaggerSecurityRequirementsDocumentFilter>();
    });
}

In Swagger UI, click on Authorize button and set value for token.

Result:

curl -X GET "http://localhost:5000/api/tenants" -H "accept: text/plain" -H "Authorization: Bearer ABCD123456"

Many people prefer to use just .keep since the convention has nothing to do with git.

Another solution is to migrate the database to e.g 2012 when you "export" the DB from e.g. Sql Server manager 2014. This is done in menu Tasks-> generate scripts when right-click on DB. Just follow this instruction:

https://www.mssqltips.com/sqlservertip/2810/how-to-migrate-a-sql-server-database-to-a-lower-version/

It generates an scripts with everything and then in your SQL server manager e.g. 2012 run the script as specified in the instruction. I have performed the test with success.

Using docker links, you can link the upstream container to the nginx container. An added feature is that docker manages the host file, which means you'll be able to refer to the linked container using a name rather than the potentially random ip.

Lambda Expression Java 8

In Java 1.8 (Java 8) this has become lot easier by using forEach method from Aggregate operations(Stream operations) that looks similar to iterators from Iterable Interface.

Just copy paste below statement to your code and rename the HashMap variable from hm to your HashMap variable to print out key-value pair.

HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
/*
 *     Logic to put the Key,Value pair in your HashMap hm
 */

// Print the key value pair in one line.
hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));

Here is an example where a Lambda Expression is used:

    HashMap<Integer,Integer> hm = new HashMap<Integer, Integer>();
    Random rand = new Random(47);
    int i=0;
    while(i<5){
        i++;
        int key = rand.nextInt(20);
        int value = rand.nextInt(50);
        System.out.println("Inserting key: "+key+" Value: "+value);
        Integer imap =hm.put(key,value);
        if( imap == null){
            System.out.println("Inserted");
        }
        else{
            System.out.println("Replaced with "+imap);
        }               
    }

    hm.forEach((k,v) -> System.out.println("key: "+k+" value:"+v));

Output:

Inserting key: 18 Value: 5
Inserted
Inserting key: 13 Value: 11
Inserted
Inserting key: 1 Value: 29
Inserted
Inserting key: 8 Value: 0
Inserted
Inserting key: 2 Value: 7
Inserted
key: 1 value:29
key: 18 value:5
key: 2 value:7
key: 8 value:0
key: 13 value:11

Also one can use Spliterator for the same.

Spliterator sit = hm.entrySet().spliterator();

UPDATE

Including documentation links to Oracle Docs. For more on Lambda go to this link and must read Aggregate Operations and for Spliterator go to this link.

EDIT: Per @sshow's comment, if you're trying to run your node app on port 80, the below is not the best way to do it. Here's a better answer: How do I run Node.js on port 80?

Original Answer:

If you want to do this to run on port 80 (or want to set the env variable more permanently),

1. Open up your bash profile vim ~/.bash_profile
2. Add the environment variable to the file export PORT=80
3. Open up the sudoers config file sudo visudo
4. Add the following line to the file exactly as so Defaults env_keep +="PORT"

Now when you run sudo node app.js it should work as desired.

Daemon Template

I wrote a daemon template following the new-style daemon: link

You can find the entire template code on GitHub: here

Main.cpp

// This function will be called when the daemon receive a SIGHUP signal.
void reload() {
    LOG_INFO("Reload function called.");
}

int main(int argc, char **argv) {
    // The Daemon class is a singleton to avoid be instantiate more than once
    Daemon& daemon = Daemon::instance();
    // Set the reload function to be called in case of receiving a SIGHUP signal
    daemon.setReloadFunction(reload);
    // Daemon main loop
    int count = 0;

You can use

if("/quit".equals(s))
   ...

or

if("/quit".compareTo(s) == 0) 
    ...

The latter makes a lexicographic comparison, and will return 0 if the two strings are the same.

You can also try this to determine the current global sql_mode value:

SELECT @@GLOBAL.sql_mode;

or session sql_mode value:

SELECT @@SESSION.sql_mode;

I also had the feeling that the SQL mode was indeed empty.

In case some wonders how to do it using Scala (using Spark 2.0.+), here you go:

scala> df.createOrReplaceTempView("TEMP_DF")
scala> val myMax = spark.sql("SELECT MAX(x) as maxval FROM TEMP_DF").
    collect()(0).getInt(0)
scala> print(myMax)
117

Yes, you can!

I think you could set the headers and still use getJSON() like this:

$.ajaxSetup({
  headers : {
    'Authorization' : 'Basic faskd52352rwfsdfs',
    'X-PartnerKey' : '3252352-sdgds-sdgd-dsgs-sgs332fs3f'
  }
});
$.getJSON('http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json', function(json) { alert("Success"); }); 

I was able to find my version of Xcode on maxOS Sierra using this command:

pkgutil --pkg-info=com.apple.pkg.CLTools_Executables | grep version

as per this answer.

For some reason none of the above Answers worked for me. As I need to pass several extra vars to my playbook in Ansbile 2.2.0, this is how I got it working (note the -e option before each var):

ansible-playbook site.yaml -i hostinv -e firstvar=false -e second_var=value2

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

UPDATE

Angular offers now the two scope methods $watchGroup (since 1.3) and $watchCollection. Those have been mentioned by @blazemonger and @kargold.

This should work independent of the types and values:

$scope.$watch('[age,name]', function () { ... }, true);

You have to set the third parameter to true in this case.

The string concatenation 'age + name' will fail in a case like this:

<button ng-init="age=42;name='foo'" ng-click="age=4;name='2foo'">click</button>

Before the user clicks the button the watched value would be 42foo (42 + foo) and after the click 42foo (4 + 2foo). So the watch function would not be called. So better use an array expression if you cannot ensure, that such a case will not appear.

PS:

As stated by @reblace in a comment, it is of course possible to access the values:

$scope.$watch('[age,name]', function (newValue, oldValue) {
    var newAge  = newValue[0];
    var newName = newValue[1];
    var oldAge  = oldValue[0];
    var oldName = oldValue[1];
}, true);

Difference between split and partition is split returns the list without delimiter and will split where ever it gets delimiter in string i.e.

x = 'http://test.com/lalala-134-431'

a,b,c = x.split(-)
print(a)
"http://test.com/lalala"
print(b)
"134"
print(c)
"431"

and partition will divide the string with only first delimiter and will only return 3 values in list

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala"
print(b)
"-"
print(c)
"134-431"

so as you want last value you can use rpartition it works in same way but it will find delimiter from end of string

x = 'http://test.com/lalala-134-431'
a,b,c = x.partition('-')
print(a)
"http://test.com/lalala-134"
print(b)
"-"
print(c)
"431"

In SQL Server 2008 or above I use the following query to find all the dependant stored procedures, user defined functions, triggers, etc. for a given table:

coalesce('.'+col_name(referenced_ID,referenced_minor_id),'')AS [referencing],
coalesce(object_schema_name(Referencing_ID)+'.','')+ --likely schema name
object_name(Referencing_ID)+ --definite entity name
coalesce('.'+col_name(referencing_ID,referencing_minor_id),'') AS [referenced]

ORDER BY [referenced]

If Subversion is already installed ,there's no need to reinstall it with the command line client tools.
Simply Goto

Start(Rightclick) ->App and Feature ->TortoiseSvn->Modify->Install command line client tools.   

From the documentation. The develop will not install the package but it will create a .egg-link in the deployment directory back to the project source code directory.

So it's like installing but instead of copying to the site-packages it adds a symbolic link (the .egg-link acts as a multiplatform symbolic link).

That way you can edit the source code and see the changes directly without having to reinstall every time that you make a little change. This is useful when you are the developer of that project hence the name develop. If you are just installing someone else's package you should use install

Actually, we really do not need to import any python library. We can separate the year, month, date using simple SQL. See the below example,

+----------+
|       _c0|
+----------+
|1872-11-30|
|1873-03-08|
|1874-03-07|
|1875-03-06|
|1876-03-04|
|1876-03-25|
|1877-03-03|
|1877-03-05|
|1878-03-02|
|1878-03-23|
|1879-01-18|

I have a date column in my data frame which contains the date, month and year and assume I want to extract only the year from the column.

df.createOrReplaceTempView("res")
sqlDF = spark.sql("SELECT EXTRACT(year from `_c0`) FROM res ")

Here I'm creating a temporary view and store the year values using this single line and the output will be,

+-----------------------+
|year(CAST(_c0 AS DATE))|
+-----------------------+
|                   1872|
|                   1873|
|                   1874|
|                   1875|
|                   1876|
|                   1876|
|                   1877|
|                   1877|
|                   1878|
|                   1878|
|                   1879|
|                   1879|
|                   1879|

Could also potentially use this script to use the system time in a variable

now=$(date +"%m_%d_%Y_%M:%S")

Which outputs as

Have a look at this excellent article at CSS-Tricks:

• px – em – % – pt – keyword

Taken from the article:

pt

The final unit of measurement that it is possible to declare font sizes in is point values (pt). Point values are only for print CSS! A point is a unit of measurement used for real-life ink-on-paper typography. 72pts = one inch. One inch = one real-life inch like-on-a-ruler. Not an inch on a screen, which is totally arbitrary based on resolution.

Just like how pixels are dead-accurate on monitors for font-sizing, point sizes are dead-accurate on paper. For the best cross-browser and cross-platform results while printing pages, set up a print stylesheet and size all fonts with point sizes.

For good measure, the reason we don't use point sizes for screen display (other than it being absurd), is that the cross-browser results are drastically different:

px

If you need fine-grained control, sizing fonts in pixel values (px) is an excellent choice (it's my favorite). On a computer screen, it doesn't get any more accurate than a single pixel. With sizing fonts in pixels, you are literally telling browsers to render the letters exactly that number of pixels in height:

Windows, Mac, aliased, anti-aliased, cross-browsers, doesn't matter, a font set at 14px will be 14px tall. But that isn't to say there won't still be some variation. In a quick test below, the results were slightly more consistent than with keywords but not identical:

Due to the nature of pixel values, they do not cascade. If a parent element has an 18px pixel size and the child is 16px, the child will be 16px. However, font-sizing settings can be using in combination. For example, if the parent was set to 16px and the child was set to larger, the child would indeed come out larger than the parent. A quick test showed me this:

"Larger" bumped the 16px of the parent into 20px, a 25% increase.

Pixels have gotten a bad wrap in the past for accessibility and usability concerns. In IE 6 and below, font-sizes set in pixels cannot be resized by the user. That means that us hip young healthy designers can set type in 12px and read it on the screen just fine, but when folks a little longer in the tooth go to bump up the size so they can read it, they are unable to. This is really IE 6's fault, not ours, but we gots what we gots and we have to deal with it.

Setting font-size in pixels is the most accurate (and I find the most satisfying) method, but do take into consideration the number of visitors still using IE 6 on your site and their accessibility needs. We are right on the bleeding edge of not needing to care about this anymore.

The file module doesn't copy files on the remote system. The src parameter is only used by the file module when creating a symlink to a file.

If you want to move/rename a file entirely on a remote system then your best bet is to use the command module to just invoke the appropriate command:

- name: Move foo to bar
  command: mv /path/to/foo /path/to/bar

If you want to get fancy then you could first use the stat module to check that foo actually exists:

- name: stat foo
  stat: path=/path/to/foo
  register: foo_stat

- name: Move foo to bar
  command: mv /path/to/foo /path/to/bar
  when: foo_stat.stat.exists

You can also use the relatively unused:

    System.Media.SystemSounds.Beep.Play();
    System.Media.SystemSounds.Asterisk.Play();
    System.Media.SystemSounds.Exclamation.Play();
    System.Media.SystemSounds.Question.Play();
    System.Media.SystemSounds.Hand.Play();

Documentation for this sounds is available in http://msdn.microsoft.com/en-us/library/system.media.systemsounds(v=vs.110).aspx

format that can be reused as shell input

Edit february 2021: bash ${var@Q}

Under bash, you could store your variable content with Parameter Expansion's @ command for Parameter transformation:

${parameter@operator}
       Parameter transformation.  The expansion is either a transforma-
       tion of the value of parameter or  information  about  parameter
       itself,  depending on the value of operator.  Each operator is a
       single letter:

       Q      The expansion is a string that is the value of  parameter
              quoted in a format that can be reused as input.
...
       A      The  expansion  is  a string in the form of an assignment
              statement or declare command  that,  if  evaluated,  will
              recreate parameter with its attributes and value.

Sample:

$ var=$'Hello\nGood world.\n'
$ echo "$var"
Hello
Good world.

$ echo "${var@Q}"
$'Hello\nGood world.\n'

$ echo "${var@A}"
var=$'Hello\nGood world.\n'

Old answer

There is a special printf format directive (%q) built for this kind of request:

printf [-v var] format [arguments]

 %q     causes printf to output the corresponding argument
        in a format that can be reused as shell input.

Some samples:

read foo
Hello world
printf "%q\n" "$foo"
Hello\ world

printf "%q\n" $'Hello world!\n'
$'Hello world!\n'

This could be used through variables too:

printf -v var "%q" "$foo
"
echo "$var"
$'Hello world\n'

Quick check with all (128) ascii bytes:

Note that all bytes from 128 to 255 have to be escaped.

for i in {0..127} ;do
    printf -v var \\%o $i
    printf -v var $var
    printf -v res "%q" "$var"
    esc=E
    [ "$var" = "$res" ] && esc=-
    printf "%02X %s %-7s\n" $i $esc "$res"
done |

Where first field is hexa value of byte, second contain E if character need to be escaped and third field show escaped presentation of character.

Why ,?

You could see some characters that don't always need to be escaped, like ,, } and {.

So not always but sometime:

echo test 1, 2, 3 and 4,5.
test 1, 2, 3 and 4,5.

or

echo test { 1, 2, 3 }
test { 1, 2, 3 }

but care:

echo test{1,2,3}
test1 test2 test3

echo test\ {1,2,3}
test 1 test 2 test 3

echo test\ {\ 1,\ 2,\ 3\ }
test  1 test  2 test  3

echo test\ {\ 1\,\ 2,\ 3\ }
test  1, 2 test  3

t = Template('This is your <span>{{ message }}</span>.')

c = Context({'message': 'Your message'})
html = t.render(c)

This is one example where using prepared statements really saves you some trouble.

In MySQL, in order to insert a null value, you must specify it at INSERT time or leave the field out which requires additional branching:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', NULL);

However, if you want to insert a value in that field, you must now branch your code to add the single quotes:

INSERT INTO table2 (f1, f2)
  VALUES ('String Value', 'String Value');

Prepared statements automatically do that for you. They know the difference between string(0) "" and null and write your query appropriately:

$stmt = $mysqli->prepare("INSERT INTO table2 (f1, f2) VALUES (?, ?)");
$stmt->bind_param('ss', $field1, $field2);

$field1 = "String Value";
$field2 = null;

$stmt->execute();

It escapes your fields for you, makes sure that you don't forget to bind a parameter. There is no reason to stay with the mysql extension. Use mysqli and it's prepared statements instead. You'll save yourself a world of pain.

The easiest way to do this, is to install a JDK and tell Eclipse to use it as the default JRE. Use the default install.

(from memory)

Open Window -> Prefences. Select Installed Java runtimes, and choose Add. Navigate to root of your JDK (\Programs...\Java) and click Ok. Then select it to be the default JRE (checkmark).

After a workspace rebuild, you should have source attached to all JRE classes.

Maybe you're talking about the Reverse Polish Notation? If yes you can find on wikipedia a very detailed step-to-step example for the conversion; if not I have no idea what you're asking :(

For a bold text, you should have this: <b> bold text</b> or <strong>bold text</strong> They have the same result.

As far as I can tell, you don't necessarily need to specify the axis when using the filter function.

new = old.filter(['A','B','D'])

returns the same dataframe as

new = old.filter(['A','B','D'], axis=1)

You can try this:

CommandArgument='<%# "scrapid=" + Eval("ScrapId")+"&"+"UserId="+ Eval("UserId")%>'

Bootstrap 4 progress bar

<div class="progress">
<div class="progress-bar" role="progressbar" style="" aria-valuenow="" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Javascript

change progress bar on next/previous page actions

var count = Number(document.getElementById('count').innerHTML); //set this on page load in a hidden field after an ajax call
var total = document.getElementById('total').innerHTML; //set this on initial page load
var pcg = Math.floor(count/total*100);        
document.getElementsByClassName('progress-bar').item(0).setAttribute('aria-valuenow',pcg);
document.getElementsByClassName('progress-bar').item(0).setAttribute('style','width:'+Number(pcg)+'%');

You use the built-in int function, and pass it the base of the input number, i.e. 2 for a binary number:

>>> int('11111111', 2)
255

Here is documentation for python2, and for python3.

I kept using this all this time

Import-module .\build_functions.ps1 -Force

First, you're missing some parentheses in your conditional:

if ($("#about").hasClass("opened")) {
  $("#about").animate({right: "-700px"}, 2000);
}

But you can also simplify this to:

$('#about.opened').animate(...);

If #about doesn't have the opened class, it won't animate.

If the problem is with the animation itself, we'd need to know more about your element positioning (absolute? absolute inside relative parent? does the parent have layout?)

• the object which implements Comparable is Fegan.

The method compareTo you are overidding in it should have a Fegan object as a parameter whereas you are casting it to a FoodItems. Your compareTo implementation should describe how a Fegan compare to another Fegan.

• To actually do your sorting, you might want to make your FoodItems implement Comparable aswell and copy paste your actual compareTo logic in it.

Easiest Way To install PDT

1. Run eclipse
2. Click on "Help", "Install New Software"
3. “Choose all available sites”, in search box type "php"(takes a while to load)
4. => “programming languages” => "PHP Development Tools", => PhP Development Tools (PDT) SDK Feature.
5. Restart eclipse
6. File new => other => php .

For the filestream:

//Check if the directory exists
if (!System.IO.Directory.Exists(@"C:\yourDirectory"))
{
    System.IO.Directory.CreateDirectory(@"C:\yourDirectory");
}

//Write the file
using (System.IO.StreamWriter outfile = new System.IO.StreamWriter(@"C:\yourDirectory\yourFile.txt"))
{
    outfile.Write(yourFileAsString);
}

You could create a function that checks every input in an input class like below

 function validateForm() {
  
    var anyFieldIsEmpty = jQuery(".myclass").filter(function () {
        return $.trim(this.value).length === 0;
    }).length > 0

    if (anyFieldIsEmpty) {
        alert("Fill all the necessary fields");
        var empty = $(".myclass").filter(function () {
            return $.trim(this.value).length === 0;
        })
        empty.css("border", "1px solid red");
        return false;
    } else {
        return true;
    }
}

What this does is it checks every input in 'myclass' and if empty it gives alert and colour the border of the input and user will recognize which input is not filled.

I got this error message from using an oracle database in a docker despite the fact i had publish port to host option "-p 1521:1521". I was using jdbc url that was using ip address 127.0.0.1, i changed it to the host machine real ip address and everything worked then.

Laravel version 6.0.2

I also had the same problem. I used

<link href="{{ asset('css/app.css') }}" rel="stylesheet" type="text/css" >
<link href="{{ asset('css/bootstrap.css') }}" rel="stylesheet">

And after moving the CSS folder from folder resource to folder public it works

onclick vs addEventListener. A matter of preference perhaps (where IE>9).

// Using closures
function onClickLink(e, index) {   
    alert(index);
    return false;
}

var div = document.getElementById('div');

for (var i = 0; i < 10; i++) {
    var link = document.createElement('a');

    link.setAttribute('href', '#');
    link.innerHTML = i + '';
    link.addEventListener('click', (function(e) {
        var index = i;
        return function(e) {
            return onClickLink(e, index);
        }
    })(), false);
    div.appendChild(link);
    div.appendChild(document.createElement('BR'));
}

How abut just using a plain data-* attribute, not as cool as a closure, but..

function onClickLink(e) {       
    alert(e.target.getAttribute('data-index'));
    return false;
}

var div = document.getElementById('div');

for (var i = 0; i < 10; i++) {
    var link = document.createElement('a');

    link.setAttribute('href', '#');
    link.setAttribute('data-index', i);
    link.innerHTML = i + ' Hello';        
    link.addEventListener('click', onClickLink, false);
    div.appendChild(link);
    div.appendChild(document.createElement('BR'));
}

To add to Lennart Regebro's answer There is even the third way that can be used:

encoded3 = str.encode(original, 'utf-8')
print(encoded3)

Anyway, it is actually exactly the same as the first approach. It may also look that the second way is a syntactic sugar for the third approach.

A programming language is a means to express abstract ideas formally, to be executed by the machine. A programming language is considered good if it contains constructs that one needs. Python is a hybrid language -- i.e. more natural and more versatile than pure OO or pure procedural languages. Sometimes functions are more appropriate than the object methods, sometimes the reverse is true. It depends on mental picture of the solved problem.

Anyway, the feature mentioned in the question is probably a by-product of the language implementation/design. In my opinion, this is a nice example that show the alternative thinking about technically the same thing.

In other words, calling an object method means thinking in terms "let the object gives me the wanted result". Calling a function as the alternative means "let the outer code processes the passed argument and extracts the wanted value".

The first approach emphasizes the ability of the object to do the task on its own, the second approach emphasizes the ability of an separate algoritm to extract the data. Sometimes, the separate code may be that much special that it is not wise to add it as a general method to the class of the object.

You have to be specific about the columns you are selecting. If your user table had four columns id, name, username, opted_in you must select exactly those four columns from the query. The syntax looks like:

INSERT INTO user (id, name, username, opted_in)
  SELECT id, name, username, opted_in 
  FROM user LEFT JOIN user_permission AS userPerm ON user.id = userPerm.user_id

However, there does not appear to be any reason to join against user_permission here, since none of the columns from that table would be inserted into user. In fact, this INSERT seems bound to fail with primary key uniqueness violations.

MySQL does not support inserts into multiple tables at the same time. You either need to perform two INSERT statements in your code, using the last insert id from the first query, or create an AFTER INSERT trigger on the primary table.

INSERT INTO user (name, username, email, opted_in) VALUES ('a','b','c',0);
/* Gets the id of the new row and inserts into the other table */
INSERT INTO user_permission (user_id, permission_id) VALUES (LAST_INSERT_ID(), 4)

Or using a trigger:

CREATE TRIGGER creat_perms AFTER INSERT ON `user`
FOR EACH ROW
BEGIN
  INSERT INTO user_permission (user_id, permission_id) VALUES (NEW.id, 4)
END

You can use CSS to accomplish this:

.disabled {
  pointer-events: none;
  cursor: default;
}

<a href="somelink.html" class="disabled">Some link</a>

Or you can use JavaScript to prevent the default action like this:

$('.disabled').click(function(e){
    e.preventDefault();
})

By default require() is not a valid function in client side javascript. I recommend you look into require.js as this does extend the client side to provide you with that function.

Update-Database –TargetMigration:"Your migration name"

For this problem I suggest this link:

https://elegantcode.com/2012/04/12/entity-framework-migrations-tips/

You get the error because if can only evaluate a logical vector of length 1.

Maybe you miss the difference between & (|) and && (||). The shorter version works element-wise and the longer version uses only the first element of each vector, e.g.:

c(TRUE, TRUE) & c(TRUE, FALSE)
# [1] TRUE FALSE

# c(TRUE, TRUE) && c(TRUE, FALSE)
[1] TRUE

You don't need the if statement at all:

mut1 <- trip$Ref.y=='G' & trip$Variant.y=='T'|trip$Ref.y=='C' & trip$Variant.y=='A'
trip[mut1, "mutType"] <- "G:C to T:A"

This copies the 5 cells to the right of the activecell. If you have a range selected, the active cell is the top left cell in the range.

Sub Copy5CellsToRight()
    ActiveCell.Offset(, 1).Resize(1, 5).Copy
End Sub

If you want to include the activecell in the range that gets copied, you don't need the offset:

Sub ExtendAndCopy5CellsToRight()
    ActiveCell.Resize(1, 6).Copy
End Sub

Note that you don't need to select before copying.

For reference, here's an sscce that illustrates the difference. Console:

Note: this answer assumes your textField is in a scrollView.

I prefer to deal with this using scrollContentInset and scrollContentOffset instead of messing with the frames of my view.

First let's listen for the keyboard notifications

//call this from viewWillAppear
-(void)addKeyboardNotifications
{
    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillShow:)
                                                 name:UIKeyboardWillShowNotification
                                               object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self
                                             selector:@selector(keyboardWillHide:)
                                                 name:UIKeyboardWillHideNotification
                                               object:nil];
}
//call this from viewWillDisappear
-(void)removeKeyboardNotifications{
    [[NSNotificationCenter default
    Center] removeObserver:self name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

Next step is to keep a property that represents the current first responder (UITextfield/ UITextVIew that currently has the keyboard).

We use the delegate methods to set this property. If you're using another component, you will need something similar.

Note that for textfield we set it in didBeginEditing and for textView in shouldBeginEditing. This is because textViewDidBeginEditing gets called after UIKeyboardWillShowNotification for some reason.

-(BOOL)textViewShouldBeginEditing:(UITextView * )textView{
    self.currentFirstResponder = textView;
    return YES;
}

-(void)textFieldDidBeginEditing:(UITextField *)textField{
    self.currentFirstResponder = textField;
}

Finally, here's the magic

- (void)keyboardWillShow:(NSNotification*)aNotification{
    NSDictionary* info = [aNotification userInfo];
    CGRect kbFrame = [[info objectForKey:UIKeyboardFrameEndUserInfoKey] CGRectValue];


    /*if currentFirstResponder is overlayed by the keyboard, move it so it bottom ends where the keyboard begins*/
    if(self.currentFirstResponder){

        //keyboard origin in currentFirstResponderFrame
        CGPoint keyboardOrigin = [self.currentFirstResponder convertPoint:kbFrame.origin fromView:nil];

        float spaceBetweenFirstResponderAndKeyboard = abs(self.currentFirstResponder.frame.size.height-keyboardOrigin.y);

        //only scroll the scrollview if keyboard overlays the first responder
        if(spaceBetweenFirstResponderAndKeyboard>0){
            //if i call setContentOffset:animate:YES it behaves differently, not sure why
            [UIView animateWithDuration:0.25 animations:^{
                [self.scrollView setContentOffset:CGPointMake(0,self.scrollView.contentOffset.y+spaceBetweenFirstResponderAndKeyboard)];
            }];
        }
    }

    //set bottom inset to the keyboard height so you can still scroll the whole content

    UIEdgeInsets contentInsets = UIEdgeInsetsMake(0.0, 0.0, kbFrame.size.height, 0.0);
    _scrollView.contentInset = contentInsets;
    _scrollView.scrollIndicatorInsets = contentInsets;

}

- (void)keyboardWillHide:(NSNotification*)aNotification{
    UIEdgeInsets contentInsets = UIEdgeInsetsZero;
    _scrollView.contentInset = contentInsets;
    _scrollView.scrollIndicatorInsets = contentInsets;
}

int64_t delayInSeconds = 0.6;
dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
     do something to the button(s)
});

Try pasting this to .htaccess and it should work.

php_value post_max_size 2000M
php_value upload_max_filesize 2500M
php_value max_execution_time 6000000
php_value max_input_time 6000000
php_value memory_limit 2500M

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

For me that have Visual Studio 2015 this works:
Search this in the start menu: Developer Command Prompt for VS2015 and run the program in the search result.
You can now execute your command in it, for example: cl /?

Some modules makes simpler data-binding in forms, for example:

react-distributed-forms

class SomeComponent extends React.Component {
  state = {
    first_name: "George"
  };

  render() {
    return (
      <Form binding={this}>
        <Input name="first_name" />
      </Form>
    );
  }
}

https://www.npmjs.com/package/react-distributed-forms#data-binding

It uses React context, so you don't have to wire together input in forms

Here's a live demo

I disagree with yydi answer saying:

If Android decides to recreate your Fragment later, it's going to call the no-argument constructor of your fragment. So overloading the constructor is not a solution.

I think it is a solution and a good one, this is exactly the reason it been developed by Java core language.

Its true that Android system can destroy and recreate your Fragment. So you can do this:

public MyFragment() {
//  An empty constructor for Android System to use, otherwise exception may occur.
}

public MyFragment(int someInt) {
    Bundle args = new Bundle();
    args.putInt("someInt", someInt);
    setArguments(args);
}

It will allow you to pull someInt from getArguments() latter on, even if the Fragment been recreated by the system. This is more elegant solution than static constructor.

For my opinion static constructors are useless and should not be used. Also they will limit you if in the future you would like to extend this Fragment and add more functionality to the constructor. With static constructor you can't do this.

Update:

Android added inspection that flag all non-default constructors with an error.
I recommend to disable it, for the reasons mentioned above.
