In Android its very Simple .Just use the Calender class to get currentTimeMillis.

Timestamp stamp = new Timestamp(Calendar.getInstance().getTimeInMillis());
Date date = new Date(stamp.getTime());
Log.d("Current date Time is   "  +date.toString());

In Java just Use System.currentTimeMillis() to get current timestamp

The ToString method on the DateTime struct can take a format parameter:

var dateAsString = DateTime.Now.ToString("yyyy-MM-dd");
// dateAsString = "2011-02-17"

Documentation for standard and custom format strings is available on MSDN.

Why don't you use Joda (org.joda.time.DateTime)? It's basically a one-liner.

Date currentDate = GregorianCalendar.getInstance().getTime();
String output = new DateTime( currentDate ).toString("yyyy-MM-dd HH:mm:ss");

// output: 2014-11-14 14:05:09

Using the DateTime class available in PHP version 5.2 it would be done like this:

$datetime = new DateTime('17 Oct 2008');
echo $datetime->format('c');

See it in action

As of PHP 5.4 you can do this as a one-liner:

echo (new DateTime('17 Oct 2008'))->format('c');

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);

Try following code will Add one day to current date

select DateAdd(day, 1, GetDate())

And in the same way can use Year, Month, Hour, Second etc. instead of day in the same function

please find the below code.

List<Date> dates = new ArrayList<Date>();

String str_date ="27/08/2010";
String end_date ="02/09/2010";

DateFormat formatter ; 

formatter = new SimpleDateFormat("dd/MM/yyyy");
Date  startDate = (Date)formatter.parse(str_date); 
Date  endDate = (Date)formatter.parse(end_date);
long interval = 24*1000 * 60 * 60; // 1 hour in millis
long endTime =endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();
while (curTime <= endTime) {
    dates.add(new Date(curTime));
    curTime += interval;
}
for(int i=0;i<dates.size();i++){
    Date lDate =(Date)dates.get(i);
    String ds = formatter.format(lDate);    
    System.out.println(" Date is ..." + ds);
}

output:

Date is ...27/08/2010
Date is ...28/08/2010
Date is ...29/08/2010
Date is ...30/08/2010
Date is ...31/08/2010
Date is ...01/09/2010
Date is ...02/09/2010

We can use date -d option

1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12

date -d '20121212' +'%Y-%m-%d'

2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format

date -d '20121212 -7 days' +'%Y-%m-%d'

3) If we are getting date in some variable say dat

dat2=$(date -d "$dat -1 days" +'%Y%m%d')

var utc = new Date().toJSON().slice(0,10).replace(/-/g,'/');_x000D_
document.write(utc);

Use the replace option if you're going to reuse the utc variable, such as new Date(utc), as Firefox and Safari don't recognize a date with dashes.

It will work.

long yourmilliseconds = System.currentTimeMillis();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd,yyyy HH:mm");    
Date resultdate = new Date(yourmilliseconds);
System.out.println(sdf.format(resultdate));

Subtract the beginning date from the end date:

endDate - beginDate

You are probably looking for:

!toDate.before(currentDate)

before() and after() test whether the date is strictly before or after. So you have to take the negation of the other one to get non strict behaviour.

Perhaps the pandas interface has changed since @Rutger answered, but in the version I'm using (0.15.2), the date_parser function receives a list of dates instead of a single value. In this case, his code should be updated like so:

dateparse = lambda dates: [pd.datetime.strptime(d, '%Y-%m-%d %H:%M:%S') for d in dates]

df = pd.read_csv(infile, parse_dates=['datetime'], date_parser=dateparse)

One issue is that reindex will fail if there are duplicate values. Say we're working with timestamped data, which we want to index by date:

df = pd.DataFrame({
    'timestamps': pd.to_datetime(
        ['2016-11-15 1:00','2016-11-16 2:00','2016-11-16 3:00','2016-11-18 4:00']),
    'values':['a','b','c','d']})
df.index = pd.DatetimeIndex(df['timestamps']).floor('D')
df

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-18  "2016-11-18 04:00:00"  d

Due to the duplicate 2016-11-16 date, an attempt to reindex:

all_days = pd.date_range(df.index.min(), df.index.max(), freq='D')
df.reindex(all_days)

fails with:

...
ValueError: cannot reindex from a duplicate axis

(by this it means the index has duplicates, not that it is itself a dup)

Instead, we can use .loc to look up entries for all dates in range:

df.loc[all_days]

yields

            timestamps             values
2016-11-15  "2016-11-15 01:00:00"  a
2016-11-16  "2016-11-16 02:00:00"  b
2016-11-16  "2016-11-16 03:00:00"  c
2016-11-17  NaN                    NaN
2016-11-18  "2016-11-18 04:00:00"  d

No offense but to check for performance of sql I executed some of the above mentioned solutiona pgsql.

Let me share you Statistics of top 3 solution approaches that I come across.

1) Took : 1.58 MS Avg

2) Took : 2.87 MS Avg

3) Took : 3.95 MS Avg

Now try this :

 SELECT * FROM table WHERE DATE_TRUNC('day', date ) >= Start Date AND DATE_TRUNC('day', date ) <= End Date

Now this solution took : 1.61 Avg.

And best solution is 1st that suggested by marco-mariani

Well, I think it would be a bad idea to replicate the code which is already present in classes like SimpleDateFormat.

On the other hand, personally I'd suggest avoiding Calendar and Date entirely if you can, and using Joda Time instead, as a far better designed date and time API. For example, you need to be aware that SimpleDateFormat is not thread-safe, so you either need thread-locals, synchronization, or a new instance each time you use it. Joda parsers and formatters are thread-safe.

I'm assuming you mean a datetime picker in a winforms application.

in your code, you can do the following:

string theDate = dateTimePicker1.Value.ToShortDateString();

or, if you'd like to specify the format of the date:

string theDate = dateTimePicker1.Value.ToString("yyyy-MM-dd");

This function will return you the date and time in the following format: YYYY:MM:DD:HH:MM:SS. It also works in Node.js.

function getDateTime() {

    var date = new Date();

    var hour = date.getHours();
    hour = (hour < 10 ? "0" : "") + hour;

    var min  = date.getMinutes();
    min = (min < 10 ? "0" : "") + min;

    var sec  = date.getSeconds();
    sec = (sec < 10 ? "0" : "") + sec;

    var year = date.getFullYear();

    var month = date.getMonth() + 1;
    month = (month < 10 ? "0" : "") + month;

    var day  = date.getDate();
    day = (day < 10 ? "0" : "") + day;

    return year + ":" + month + ":" + day + ":" + hour + ":" + min + ":" + sec;

}

You can also get DateTime object from timestamp, including your current daylight saving time:

public DateTime getDateTimeFromTimestamp(Long value) {
    TimeZone timeZone = TimeZone.getDefault();
    long offset = timeZone.getOffset(value);
    if (offset < 0) {
        value -= offset;
    } else {
        value += offset;
    }
    return new DateTime(value);
}    

Apache Commons Lang has a DurationFormatUtils that has very helpful methods like formatDurationWords.

In angularjs moment="^1.3.0"

moment('15-01-1979', 'DD-MM-YYYY').subtract(1,'days').format(); //14-01-1979
or
moment('15-01-1979', 'DD-MM-YYYY').add(1,'days').format(); //16-01-1979
``

Randall, here are the VB expressions I found to work in SSRS to obtain the first and last days of any month, using the current month as a reference:

First day of last month:

=dateadd("m",-1,dateserial(year(Today),month(Today),1)) 

First day of this month:

=dateadd("m",0,dateserial(year(Today),month(Today),1)) 

First day of next month:

=dateadd("m",1,dateserial(year(Today),month(Today),1)) 

Last day of last month:

=dateadd("m",0,dateserial(year(Today),month(Today),0))

Last day of this month:

=dateadd("m",1,dateserial(year(Today),month(Today),0))

Last day of next month:

=dateadd("m",2,dateserial(year(Today),month(Today),0))

The MSDN documentation for the VisualBasic DateSerial(year,month,day) function explains that the function accepts values outside the expected range for the year, month, and day parameters. This allows you to specify useful date-relative values. For instance, a value of 0 for Day means "the last day of the preceding month". It makes sense: that's the day before day 1 of the current month.

See DateDiff:

DECLARE @startdate date = '2011/1/1'
DECLARE @enddate date = '2011/3/1'
SELECT DATEDIFF(day, @startdate, @enddate)

            var timecompare = {
            tstr: "",
            get: function (current_time, startTime, endTime) {
                this.tstr = "";
                var s = current_time.split(":"), t1 = tm1.split(":"), t2 = tm2.split(":"), t1s = Number(t1[0]), t1d = Number(t1[1]), t2s = Number(t2[0]), t2d = Number(t2[1]);

                if (t1s < t2s) {
                    this.t(t1s, t2s);
                }

                if (t1s > t2s) {
                    this.t(t1s, 23);
                    this.t(0, t2s);
                }

                var saat_dk = Number(s[1]);

                if (s[0] == tm1.substring(0, 2) && saat_dk >= t1d)
                    return true;
                if (s[0] == tm2.substring(0, 2) && saat_dk <= t2d)
                    return true;
                if (this.tstr.indexOf(s[0]) != 1 && this.tstr.indexOf(s[0]) != -1 && !(this.tstr.indexOf(s[0]) == this.tstr.length - 2))
                    return true;

                return false;

            },
            t: function (ii, brk) {
                for (var i = 0; i <= 23; i++) {
                    if (i < ii)
                        continue;
                    var s = (i < 10) ? "0" + i : i + "";
                    this.tstr += "," + s;
                    if (brk == i)
                        break;
                }
            }};

German Variant, but could be adapted to Iso

export function isLeapYear(year) {
  return (
    year % 4 === 0 && (year % 100 != 0 || year % 1000 === 0 || year % 400 === 0)
  )
}

export function isValidGermanDate(germanDate) {
  if (
    !germanDate ||
    germanDate.length < 5 ||
    germanDate.split('.').length < 3
  ) {
    return false
  }

  const day = parseInt(germanDate.split('.')[0])
  const month = parseInt(germanDate.split('.')[1])
  const year = parseInt(germanDate.split('.')[2])

  if (isNaN(month) || isNaN(day) || isNaN(year)) {
    return false
  }

  if (month < 1 || month > 12) {
    return false
  }

  if (day < 1 || day > 31) {
    return false
  }

  if ((month === 4 || month === 6 || month === 9 || month === 11) && day > 30) {
    return false
  }

  if (isLeapYear(year)) {
    if (month === 2 && day > 29) {
      return false
    }
  } else {
    if (month === 2 && day > 28) {
      return false
    }
  }

  return true
}

Using to_char:

select to_char(sysdate, 'YYYY') from dual;

In your example you can use something like:

BETWEEN trunc(sysdate, 'YEAR') 
    AND add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60;

The comparison values are exactly what you request:

select trunc(sysdate, 'YEAR') begin_year
     , add_months(trunc(sysdate, 'YEAR'), 12)-1/24/60/60 last_second_year
from dual;

BEGIN_YEAR  LAST_SECOND_YEAR
----------- ----------------
01/01/2009  31/12/2009

Just extending on the many other excellent answers - if you are using jQuery - you could just do something like

$.fn.getMonthName = function(date) {

    var monthNames = [
    "January", "February", "March",
    "April", "May", "June",
    "July", "August", "September",
    "October", "November", "December"
    ];

    return monthNames[date.getMonth()];

};

where date is equal to the var d = new Date(somevalue). The primary advantage of this is per @nickf said about avoiding the global namespace.

java.util.Date constructor with parameters like new Date(int year, int month, int date, int hrs, int min). is deprecated and preferably do not use it any more. Oracle docs prefers the way over java.util.Calendar. So you can set any date and instantiate Date object through the getTime() method.

Calendar calendar = Calendar.getInstance();
calendar.set(2018, 11, 31, 59, 59, 59);
Date happyNewYearDate = calendar.getTime();

Notice that month number starts from 0

Few years later, I second Bobby Jack's observation that last 24 hrs is not today!!! And I am surprised that the answer was so much upvoted...

To compare if a certain date is less, equal or greater than another, first you need to turn them "down" to beginning of the day. In other words, make sure that you're talking about same 00:00:00 time in both dates. This can be simply and elegantly done as:

strtotime("today") <=> strtotime($var)

if $var has the time part on 00:00:00 like the OP specified.

Replace <=> with whatever you need (or keep it like this in php 7)

Also, obviously, we're talking about same timezone for both. For list of supported TimeZones

Simply cast your timestamp AS DATE, like this:

SELECT CAST(tstamp AS DATE)

SQLFiddle Demo

In other words, your statement would look like this:

SELECT SUM(transaction_amount)
FROM mytable
WHERE Card_No='123'
  AND CAST(transaction_date AS DATE) = target_date

What is nice about CAST is that it works exactly the same on most SQL engines (SQL Server, PostgreSQL, MySQL), and is much easier to remember how to use it. Methods using CONVERT() or TO_DATE() are specific to each SQL engine and make your code non-portable.

For those who need the answer at work and creating function is forbidden by your DBA, the following solution will work:

select *,
cast(DATEADD(day, -1*(DATEPART(WEEKDAY, YouDate)-1), YourDate) as DATE) as WeekStart
From.....

This gives the start of that week. Here I assume that Sundays are the start of weeks. If you think that Monday is the start, you should use:

select *,
cast(DATEADD(day, -1*(DATEPART(WEEKDAY, YouDate)-2), YourDate) as DATE) as WeekStart
From.....

java.time

The accepted Answer by ppeterka is correct. Your abuse of the formatting pattern results in an erroneous display of data, while the internal value is always limited milliseconds.

The troublesome SimpleDateFormat and Date classes you are using are now legacy, supplanted by the java.time classes. The java.time classes handle nanoseconds resolution, much finer than the milliseconds limit of the legacy classes.

The equivalent to java.util.Date is java.time.Instant. You can even convert between them using new methods added to the old classes.

Instant instant = myJavaUtilDate.toInstant() ;

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).

Capture the current moment in UTC. Java 8 captures the current moment in milliseconds, while a new Clock implementation in Java 9 captures the moment in finer granularity, typically microseconds though it depends on the capabilities of your computer hardware clock & OS & JVM implementation.

Instant instant = Instant.now() ;

Generate a String in standard ISO 8601 format.

String output = instant.toString() ;

2018-02-02T00:28:02.487114Z

To generate strings in other formats, search Stack Overflow for DateTimeFormatter, already covered many times.

To adjust into a time zone other than UTC, use ZonedDateTime.

ZonedDateTime zdt = instant.atZone( ZoneId.of( "Pacific/Auckland" ) ) ;

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.

Where to obtain the java.time classes?

  • 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, 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.

Use:

$name = jdmonthname(gregoriantojd($monthNumber, 1, 1), CAL_MONTH_GREGORIAN_LONG);

I think your date data should look like 2013-08-14.

<?php
 $yrdata= strtotime('2013-08-14');
    echo date('M-Y', $yrdata);
 ?>
// Output is Aug-2013

According to http://blog.dygraphs.com/2012/03/javascript-and-dates-what-mess.html the format "yyyy/mm/dd" solves the usual problems. He says: "Stick to "YYYY/MM/DD" for your date strings whenever possible. It's universally supported and unambiguous. With this format, all times are local." I've set tests: http://jsfiddle.net/jlanus/ND2Qg/432/ This format: + avoids the day and month order ambiguity by using y m d ordering and a 4-digit year + avoids the UTC vs. local issue not complying with ISO format by using slashes + danvk, the dygraphs guy, says that this format is good in all browsers.

You can do that:

function formatAMPM(date) { // This is to display 12 hour format like you asked
  var hours = date.getHours();
  var minutes = date.getMinutes();
  var ampm = hours >= 12 ? 'pm' : 'am';
  hours = hours % 12;
  hours = hours ? hours : 12; // the hour '0' should be '12'
  minutes = minutes < 10 ? '0'+minutes : minutes;
  var strTime = hours + ':' + minutes + ' ' + ampm;
  return strTime;
}

var myDate = new Date();
var displayDate = myDate.getMonth()+ '/' +myDate.getDate()+ '/' +myDate.getFullYear()+ ' ' +formatAMPM(myDate);
console.log(displayDate);

Fiddle

Java Date to int conversion:

public static final String DATE_FORMAT_INT = "yyyyMMdd";

public static String format(Date date, String format) {
    return isNull(date) ?  
    null : new SimpleDateFormat(format).format(date);
}

public static Integer getDateInt(Date date) {
    if (isNull(date)) {
        throw new IllegalArgumentException("Date must not be NULL");
    }

    return parseInt(format(date, DATE_FORMAT_INT));
}

Everybody seems to refer to date being a column in the table.
I dont think this is good practice. The word date might just be a keyword in some coding language (maybe Oracle) so please change the columnname date to maybe JDate.
So will the following work better:

SELECT * FROM jokes WHERE JDate >= CURRENT_DATE() ORDER BY JScore DESC;

So we have a table called Jokes with columns JScore and JDate.

>>> import datetime
>>> datetime.date.fromordinal(datetime.date.today().toordinal()-1).strftime("%F")
'2015-05-26'

Just do:

SELECT CAST(date_variable AS date)

or with with PostgreSQL:

SELECT date_variable::date

I should like to contribute the modern answer. This involves using java.time, the modern Java date and time API, and not the old Date nor Calendar except where there’s no way to avoid it.

Your issue is very likely really a timezone issue. When it is Tue Aug 09 00:00:00 IST 2011, in time zones west of IST midnight has not yet been reached. It is still Aug 8. If for example your API for putting the date into Excel expects UTC, the date will be the day before the one you intended. I believe the real and good solution is to produce a date-time of 00:00 UTC (or whatever time zone or offset is expected and used at the other end).

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    ZonedDateTime utcDateDime = yourDate.atStartOfDay(ZoneOffset.UTC);
    System.out.println(utcDateDime);

This prints

2018-02-27T00:00Z

Z means UTC (think of it as offset zero from UTC or Zulu time zone). Better still, of course, if you could pass the LocalDate from the first code line to Excel. It doesn’t include time-of-day, so there is no confusion possible. On the other hand, if you need an old-fashioned Date object for that, convert just before handing the Date on:

    Date oldfashionedDate = Date.from(utcDateDime.toInstant());
    System.out.println(oldfashionedDate);

On my computer this prints

Tue Feb 27 01:00:00 CET 2018

Don’t be fooled, it is correct. My time zone (Central European Time) is at offset +01:00 from UTC in February (standard time), so 01:00:00 here is equal to 00:00:00 UTC. It’s just Date.toString() grabbing the JVMs time zone and using it for producing the string.

How can I set it to something like 5:30 pm?

To answer your direct question directly, if you have a ZonedDateTime, OffsetDateTime or LocalDateTime, in all of these cases the following will accomplish what you asked for:

    yourDateTime = yourDateTime.with(LocalTime.of(17, 30));

If yourDateTime was a LocalDateTime of 2018-02-27T00:00, it will now be 2018-02-27T17:30. Similarly for the other types, only they include offset and time zone too as appropriate.

If you only had a date, as in the first snippet above, you can also add time-of-day information to it:

    LocalDate yourDate = LocalDate.of(2018, Month.FEBRUARY, 27);
    LocalDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30));

For most purposes you should prefer to add the time-of-day in a specific time zone, though, for example

    ZonedDateTime dateTime = yourDate.atTime(LocalTime.of(17, 30))
            .atZone(ZoneId.of("Asia/Kolkata"));

This yields 2018-02-27T17:30+05:30[Asia/Kolkata].

Date and Calendar vs java.time

The Date class that you use as well as Calendar and SimpleDateFormat used in the other answers are long outdated, and SimpleDateFormat in particular has proven troublesome. In all cases the modern Java date and time API is so much nicer to work with. Which is why I wanted to provide this answer to an old question that is still being visited.

Link: Oracle Tutorial Date Time, explaining how to use java.time.

$date= new DateTime($row['your_date']) ;  
echo $date->format('Y-m-d');

@Amjad, good idea, but a better implementation would be:

Date.prototype.setUTCTime = function(UTCTimestamp) {
    var UTCDate = new Date(UTCTimestamp);
    this.setUTCFullYear(UTCDate.getFullYear(), UTCDate.getMonth(), UTCDate.getDate());
    this.setUTCHours(UTCDate.getHours(), UTCDate.getMinutes(), UTCDate.getSeconds(), UTCDate.getMilliseconds());
    return this.getTime();
}

You can use the date() function:

date('w'); // day of week

or

date('l'); // dayname

Example function to get the day nr.:

function getWeekday($date) {
    return date('w', strtotime($date));
}

echo getWeekday('2012-10-11'); // returns 4

You can do that with datetime.strptime()

Example:

>>> from datetime import datetime
>>> datetime.strptime('2012-02-10' , '%Y-%m-%d')
datetime.datetime(2012, 2, 10, 0, 0)
>>> _.isoweekday()
5

You can find the table with all the strptime directive here.

To increment by 2 days if .isweekday() == 6, you can use timedelta():

>>> import datetime
>>> date = datetime.datetime.strptime('2012-02-11' , '%Y-%m-%d')
>>> if date.isoweekday() == 6:
...     date += datetime.timedelta(days=2)
... 
>>> date
datetime.datetime(2012, 2, 13, 0, 0)
>>> date.strftime('%Y-%m-%d')   # if you want a string again
'2012-02-13'

This should do what you want:

import datetime
yesterday = datetime.datetime.now() - datetime.timedelta(days = 1)
print yesterday.strftime("%m%d%y")

 $endOfCycle = date("Y-m", mktime(0, 0, 0, date("m", time())+1 , 15, date("m", time())));

As Per documentation of moment js,

There is Precise Range plugin, written by Rob Dawson, can be used to display exact, human-readable representations of date/time ranges, url :http://codebox.org.uk/pages/moment-date-range-plugin

moment("2014-01-01 12:00:00").preciseDiff("2015-03-04 16:05:06");
// 1 year 2 months 3 days 4 hours 5 minutes 6 seconds

moment.preciseDiff("2014-01-01 12:00:00", "2014-04-20 12:00:00");
// 3 months 19 days

Try to copy this one in your code, then use the method to get the age.

public static int getAge(Date birthday)
{
    GregorianCalendar today = new GregorianCalendar();
    GregorianCalendar bday = new GregorianCalendar();
    GregorianCalendar bdayThisYear = new GregorianCalendar();

    bday.setTime(birthday);
    bdayThisYear.setTime(birthday);
    bdayThisYear.set(Calendar.YEAR, today.get(Calendar.YEAR));

    int age = today.get(Calendar.YEAR) - bday.get(Calendar.YEAR);

    if(today.getTimeInMillis() < bdayThisYear.getTimeInMillis())
        age--;

    return age;
}

try this

html

<div ng-controller="MyCtrl">
  Hello, {{newDate | date:'MM/dd/yyyy'}}!
</div>

JS

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    var collectionDate = '2002-04-26T09:00:00'; 

    $scope.newDate =new Date(collectionDate);
}

Demo

I believe +%s is seconds since epoch. It's timezone invariant.

I fixed it with Datejs

This is alerting the first day:

var fd = Date.today().clearTime().moveToFirstDayOfMonth();
var firstday = fd.toString("MM/dd/yyyy");
alert(firstday);

This is for the last day:

var ld = Date.today().clearTime().moveToLastDayOfMonth();
var lastday = ld.toString("MM/dd/yyyy");
alert(lastday);

String start_dt = "2011-01-31";

DateFormat parser = new SimpleDateFormat("yyyy-MM-dd"); 
Date date = (Date) parser.parse(start_dt);

DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy"); 
System.out.println(formatter.format(date));

Prints: 01-31-2011

What you could do is creating an instance of a GregorianCalendar and then set the Date as a start time:

Date date;
Calendar myCal = new GregorianCalendar();
myCal.setTime(date);

However, another approach is to not use Date at all. You could use an approach like this:

private Calendar startTime;
private long duration;
private long startNanos;   //Nano-second precision, could be less precise
...
this.startTime = Calendar.getInstance();
this.duration = 0;
this.startNanos = System.nanoTime();

public void setEndTime() {
        this.duration = System.nanoTime() - this.startNanos;
}

public Calendar getStartTime() {
        return this.startTime;
}

public long getDuration() {
        return this.duration;
}

In this way you can access both the start time and get the duration from start to stop. The precision is up to you of course.

java.time

Using the java.time framework built into Java 8 and later.

import java.time.LocalDateTime;
import java.time.Instant;
import java.time.ZoneId;

long epoch = Long.parseLong("1081157732");
Instant instant = Instant.ofEpochSecond(epoch);
ZonedDateTime.ofInstant(instant, ZoneOffset.UTC); # ZonedDateTime = 2004-04-05T09:35:32Z[UTC]

In this case you should better use ZonedDateTime to mark it as date in UTC time zone because Epoch is defined in UTC in Unix time used by Java.

ZoneOffset contains a handy constant for the UTC time zone, as seen in last line above. Its superclass, ZoneId can be used to adjust into other time zones.

ZoneId zoneId = ZoneId.of( "America/Montreal" );

import datetime
datetime.datetime.strptime('24052010', '%d%m%Y').date()

select to_char(sysdate,'DAY') from dual; It's work try it

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

var d1 = Date.parse("2012-11-01");
var d2 = Date.parse("2012-11-04");
if (d1 < d2) {
    alert ("Error!");
}

Demo Jsfiddle

Typescript recognizes the Date interface out of the box - just like you would with a number, string, or custom type. So Just use:

myDate : Date;

DECLARE @dayval int,
 @monthval int,
 @yearval int

SET @dayval = 1
SET @monthval = 1
SET @yearval = 2011


DECLARE @dtDateSerial datetime

        SET @dtDateSerial = DATEADD(day, @dayval-1,
                                DATEADD(month, @monthval-1,
                                    DATEADD(year, @yearval-1900, 0)
                                )
                            )

DECLARE @weekno int
SET @weekno = 53


DECLARE @weekstart datetime
SET @weekstart = dateadd(day, 7 * (@weekno -1) - datepart (dw, @dtDateSerial), @dtDateSerial)

DECLARE @weekend datetime
SET @weekend = dateadd(day, 6, @weekstart)

SELECT @weekstart, @weekend

Easiest solution is:

const todayDate = Date.now();
return new Date(todayDate + 1000 * 60 * 60 * 24 * 30* X); 

where X is the number of months we want to add.

You can make use of java.util.Date instead of Timestamp :

String timeStamp = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss").format(new Date());

Use "E"

SimpleDateFormat has a constructor which takes the locale, have you tried that?

http://java.sun.com/javase/6/docs/api/java/text/SimpleDateFormat.html

Something like new SimpleDateFormat("your-pattern-here", Locale.getDefault());

IF YOU CAN AVOID IT.. DON'T DO IT

Databases aren't really designed for this, you are effectively trying to create data (albeit a list of dates) within a query.

For anyone who has an application layer above the DB query the simplest solution is to fill in the blank data there.

You'll more than likely be looping through the query results anyway and can implement something like this:

loop_date = start_date

while (loop_date <= end_date){

  if(loop_date in db_data) {
    output db_data for loop_date
  }
  else {
    output default_data for loop_date
  }

  loop_date = loop_date + 1 day
}

The benefits of this are reduced data transmission; simpler, easier to debug queries; and no worry of over-flowing the calendar table.

You have to parse all of the input string, you cannot just ignore parts.

from datetime import date, datetime

for item in j:
    st = datetime.strptime(item['start'], '%A %d %B %H:%M')

    if st.date() == date.today():
        item['start'] = st.time()

Here, we compare the date to today's date by using more datetime objects instead of trying to use strings.

The alternative is to only pass in part of the item['start'] string (splitting out just the time), but there really is no point here, not when you could just parse everything in one step first.

Cursor cursor = db.query(TABLE_NAME, new String[] {"_id", "title", "title_raw", "timestamp"},

Here's an update for those looking for a tidyverse method to extract hh:mm::ss.sssss from a POSIXct object. Note that time zone is not included in the output.

library(hms)
as_hms(times)

java.util.Date temp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS").parse("2012-07-10 14:58:00.000000");

The mm is minutes you want MM

CODE

public class Test {

    public static void main(String[] args) throws ParseException {
        java.util.Date temp = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSS")
                .parse("2012-07-10 14:58:00.000000");
        System.out.println(temp);
    }
}

Prints:

Tue Jul 10 14:58:00 EDT 2012

JavaScript perfectly supports date difference out of the box

https://jsfiddle.net/b9chris/v5twbe3h/

var msMinute = 60*1000, 
    msDay = 60*60*24*1000,
    a = new Date(2012, 2, 12, 23, 59, 59),
    b = new Date("2013 march 12");


console.log(Math.floor((b - a) / msDay) + ' full days between'); // 364
console.log(Math.floor(((b - a) % msDay) / msMinute) + ' full minutes between'); // 0

Now some pitfalls. Try this:

console.log(a - 10); // 1331614798990
console.log(a + 10); // mixed string

So if you have risk of adding a number and Date, convert Date to number directly.

console.log(a.getTime() - 10); // 1331614798990
console.log(a.getTime() + 10); // 1331614799010

My fist example demonstrates the power of Date object but it actually appears to be a time bomb

To get Correct Week Count for Date 2018-12-31 Please use below Code

$day_count = date('N',strtotime('2018-12-31'));
$week_count = date('W',strtotime('2018-12-31'));    


if($week_count=='01' && date('m',strtotime('2018-12-31'))==12){
    $yr_count = date('y',strtotime('2018-12-31')) + 1;
}else{
    $yr_count = date('y',strtotime('2018-12-31'));
}

You can use:

var tomorrow = new Date();
tomorrow.setDate(new Date().getDate()+1);

For example, since there are 30 days in April, the following code will output May 1:

var day = new Date('Apr 30, 2000');
console.log(day); // Apr 30 2000

var nextDay = new Date(day);
nextDay.setDate(day.getDate() + 1);
console.log(nextDay); // May 01 2000    

See fiddle.

it went OK when i used Locale.US parametre in SimpleDateFormat

String dateString = "15 May 2013 17:38:34 +0300";
System.out.println(dateString);

SimpleDateFormat dateFormat = new SimpleDateFormat("dd MMM yyyy HH:mm:ss Z", Locale.US);
DateFormat targetFormat = new SimpleDateFormat("dd MMM yyyy HH:mm", Locale.getDefault());
String formattedDate = null;
Date convertedDate = new Date();
try {
     convertedDate = dateFormat.parse(dateString);
System.out.println(dateString);
formattedDate = targetFormat.format(convertedDate);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
 System.out.println(convertedDate);

You could use new GregorianCalendar(theYear, theMonth, theDay).getTime():

public GregorianCalendar(int year, int month, int dayOfMonth)

Constructs a GregorianCalendar with the given date set in the default time zone with the default locale.

Non C++11 solution: With the <ctime> header, you could use strftime. Make sure your buffer is large enough, you wouldn't want to overrun it and wreak havoc later.

#include <iostream>
#include <ctime>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;
  char buffer[80];

  time (&rawtime);
  timeinfo = localtime(&rawtime);

  strftime(buffer,sizeof(buffer),"%d-%m-%Y %H:%M:%S",timeinfo);
  std::string str(buffer);

  std::cout << str;

  return 0;
}

select to_char(sysdate, 'Month') from dual

in your example will be:

select to_char(to_date('15-11-2010', 'DD-MM-YYYY'), 'Month') from dual

This is the most simple solution for me:

just the current date

$tStamp = Get-Date -format yyyy_MM_dd_HHmmss

current date with some months added

$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd

I think you should not rely on the implicit conversion. It is a bad practice.

Instead you should try like this:

datenum >= to_date('11/26/2013','mm/dd/yyyy')

or like

datenum >= date '2013-09-01'

I wouldn't use a Regex for this, but rather just split the string and check that the date is valid:

list($year, $month, $day, $hour, $minute, $second) = preg_split('%( |-|:)%', $mydatestring);
if(!checkdate($month, $day, $year)) {
     /* print error */
} 
/* check $hour, $minute and $second etc */

I use moment along with new Date to handle cases of undefined data values:

const date = moment(new Date("2016-10-19"));

because of: moment(undefined).isValid() == true

where as the better way: moment(new Date(undefined)).isValid() == false

You can use

DELETE from Table WHERE Date > CONVERT(VARCHAR, GETDATE(), 101);

Saved date as TEXT( 20/10/2013 03:26 ) To do query and to select records between dates?

Better version is:

SELECT TIMSTARTTIMEDATE 
FROM TIMER 
WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)
||substr(TIMSTARTTIMEDATE,4,2)
||substr(TIMSTARTTIMEDATE,1,2)) 
BETWEEN DATE(20131020) AND DATE(20131021);

the substr from 20/10/2013 gives 20131020 date format DATE(20131021) - that makes SQL working with dates and using date and time functions.

OR

SELECT TIMSTARTTIMEDATE 
FROM TIMER 
WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)
||'-'
||substr(TIMSTARTTIMEDATE,4,2)
||'-'
||substr(TIMSTARTTIMEDATE,1,2)) 
BETWEEN DATE('2013-10-20') AND DATE('2013-10-21');

and here is in one line

SELECT TIMSTARTTIMEDATE FROM TIMER WHERE DATE(substr(TIMSTARTTIMEDATE,7,4)||'-'||substr(TIMSTARTTIMEDATE,4,2)||'-'||substr(TIMSTARTTIMEDATE,1,2)) BETWEEN DATE('2013-10-20') AND DATE('2013-10-21');

I dont know if you want to achieve that in js or java, in js the simplest way to get the unix timestampt (this is time in seconds from 1/1/1970) it's as follows:

var myDate = new Date();
console.log(+myDate); // +myDateObject give you the unix from that date

I think the correct answer should be java.sql.Timestamp is NOT timezone specific. Timestamp is a composite of java.util.Date and a separate nanoseconds value. There is no timezone information in this class. Thus just as Date this class simply holds the number of milliseconds since January 1, 1970, 00:00:00 GMT + nanos.

In PreparedStatement.setTimestamp(int parameterIndex, Timestamp x, Calendar cal) Calendar is used by the driver to change the default timezone. But Timestamp still holds milliseconds in GMT.

API is unclear about how exactly JDBC driver is supposed to use Calendar. Providers seem to feel free about how to interpret it, e.g. last time I worked with MySQL 5.5 Calendar the driver simply ignored Calendar in both PreparedStatement.setTimestamp and ResultSet.getTimestamp.

This:

STR_TO_DATE(t.datestring, '%d/%m/%Y')

...will convert the string into a datetime datatype. To be sure that it comes out in the format you desire, use DATE_FORMAT:

DATE_FORMAT(STR_TO_DATE(t.datestring, '%d/%m/%Y'), '%Y-%m-%d')

If you can't change the datatype on the original column, I suggest creating a view that uses the STR_TO_DATE call to convert the string to a DateTime data type.

<?php 
 $current = strtotime(date("Y-m-d"));
 $date    = strtotime("2014-09-05");

 $datediff = $date - $current;
 $difference = floor($datediff/(60*60*24));
 if($difference==0)
 {
    echo 'today';
 }
 else if($difference > 1)
 {
    echo 'Future Date';
 }
 else if($difference > 0)
 {
    echo 'tomorrow';
 }
 else if($difference < -1)
 {
    echo 'Long Back';
 }
 else
 {
    echo 'yesterday';
 }  
?>

If you are using moment.js:

moment().month("Jan").format("M");

I try with this, no modifications on the css.

if you want to get the week number with the year use: "%Y-W%V":

e.g    yearAndweeks <- strftime(dates, format = "%Y-W%V")

so

> strftime(c("2014-03-16", "2014-03-17","2014-03-18", "2014-01-01"), format = "%Y-W%V")

becomes:

[1] "2014-W11" "2014-W12" "2014-W12" "2014-W01"

just use the jQuery datepicker UI library and convert both your strings into date format, then you can easily compare. following link might be useful

The solution above not working for the latest version on PostgreSQL. I found this way to convert epoch time being stored in number and int column type is on PostgreSQL 13:

SELECT TIMESTAMP 'epoch' + (<table>.field::int) * INTERVAL '1 second' as started_on from <table>;

For more detail explanation, you can see here https://www.yodiw.com/convert-epoch-time-to-timestamp-in-postgresql/#more-214

You can use dateutil.parser.parse (install with python -m pip install python-dateutil) to parse strings into datetime objects.

dateutil.parser.parse will attempt to guess the format of your string, if you know the exact format in advance then you can use datetime.strptime which you supply a format string to (see Brent Washburne's answer).

from dateutil.parser import parse

a = "2012-10-09T19:00:55Z"

b = parse(a)

print(b.weekday())
# 1 (equal to a Tuesday)

SELECT TIMESTAMPDIFF(HOUR,NOW(),'2013-05-15 10:23:23')
   calculates difference in hour.(for days--> you have to define day replacing hour
SELECT DATEDIFF('2012-2-2','2012-2-1')

SELECT TO_DAYS ('2012-2-2')-TO_DAYS('2012-2-1')

Function:

  var dates = [],
      currentDate = startDate,
      addDays = function(days) {
        var date = new Date(this.valueOf());
        date.setDate(date.getDate() + days);
        return date;
      };
  while (currentDate <= endDate) {
    dates.push(currentDate);
    currentDate = addDays.call(currentDate, 1);
  }
  return dates;
};

Usage:

var dates = getDatesRange(new Date(2019,01,01), new Date(2019,01,25));                                                                                                           
dates.forEach(function(date) {
  console.log(date);
});

Hope it helps you

Here is a query to find all product sales that were running during the month of August

• Find Product_sales there were active during the month of August
• Include anything that started before the end of August
• Exclude anything that ended before August 1st

Also adds a case statement to validate the query

SELECT start_date, 
       end_date, 
       CASE 
         WHEN start_date <= '2015-08-31' THEN 'true' 
         ELSE 'false' 
       END AS started_before_end_of_month, 
       CASE 
         WHEN NOT end_date <= '2015-08-01' THEN 'true' 
         ELSE 'false' 
       END AS did_not_end_before_begining_of_month 
FROM   product_sales 
WHERE  start_date <= '2015-08-31' 
       AND end_date >= '2015-08-01' 
ORDER  BY start_date; 

If you'd like to initialize the array to values other than 0, with gcc you can do:

int array[1024] = { [ 0 ... 1023 ] = -1 };

This is a GNU extension of C99 Designated Initializers. In older GCC, you may need to use -std=gnu99 to compile your code.

If you need a quick work around in Chrome for ajax requests, this chrome plugin automatically allows you to access any site from any source by adding the proper response header

Chrome Extension Allow-Control-Allow-Origin: *

On the outermost level, a JSON object starts with a { and end with a }.

Sample data:

{
    "cars": {
        "Nissan": [
            {"model":"Sentra", "doors":4},
            {"model":"Maxima", "doors":4},
            {"model":"Skyline", "doors":2}
        ],
        "Ford": [
            {"model":"Taurus", "doors":4},
            {"model":"Escort", "doors":4}
        ]
    }
}

If the JSON is assigned to a variable called data, then accessing it would be like the following:

data.cars['Nissan'][0].model   // Sentra
data.cars['Nissan'][1].model   // Maxima
data.cars['Nissan'][2].doors   // 2

for (var make in data.cars) {
    for (var i = 0; i < data.cars[make].length; i++) {
        var model = data.cars[make][i].model;
        var doors = data.cars[make][i].doors;
        alert(make + ', ' + model + ', ' + doors);
    }
}

Another approach (using an associative array for car models rather than an indexed array):

{
    "cars": {
        "Nissan": {
            "Sentra": {"doors":4, "transmission":"automatic"},
            "Maxima": {"doors":4, "transmission":"automatic"}
        },
        "Ford": {
            "Taurus": {"doors":4, "transmission":"automatic"},
            "Escort": {"doors":4, "transmission":"automatic"}
        }
    }
}

data.cars['Nissan']['Sentra'].doors   // 4
data.cars['Nissan']['Maxima'].doors   // 4
data.cars['Nissan']['Maxima'].transmission   // automatic

for (var make in data.cars) {
    for (var model in data.cars[make]) {
        var doors = data.cars[make][model].doors;
        alert(make + ', ' + model + ', ' + doors);
    }
}

Edit:

Correction: A JSON object starts with { and ends with }, but it's also valid to have a JSON array (on the outermost level), that starts with [ and ends with ].

Also, significant syntax errors in the original JSON data have been corrected: All key names in a JSON object must be in double quotes, and all string values in a JSON object or a JSON array must be in double quotes as well.

See:

• JSON specification
• JSONLint - The JSON validator

    d['ModDate'] = datetime.datetime.today()

Why don't you check if text.trim() has a different length? :

if(text.length() == text.trim().length() || otherConditions){
    //your code
}

What I do is something just a little bit different from @Chase answer:

var employees = {};

// ...and then:
employees.accounting = new Array();

for (var i = 0; i < someArray.length; i++) {
    var temp_item = someArray[i];

    // Maybe, here make something like:
    // temp_item.name = 'some value'

    employees.accounting.push({
        "firstName" : temp_item.firstName,
        "lastName"  : temp_item.lastName,
        "age"       : temp_item.age
    });
}

And that work form me!

I hope it could be useful for some body else!

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

That is not how the PUBLIC_URL variable is used. According to the documentation, you can use the PUBLIC_URL in your HTML:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

Or in your JavaScript:

render() {
  // Note: this is an escape hatch and should be used sparingly!
  // Normally we recommend using `import` for getting asset URLs
  // as described in “Adding Images and Fonts” above this section.
  return <img src={process.env.PUBLIC_URL + '/img/logo.png'} />;
}

The PUBLIC_URL is not something you set to a value of your choosing, it is a way to store files in your deployment outside of Webpack's build system.

To view this, run your CRA app and add this to the src/index.js file:

console.log('public url: ', process.env.PUBLIC_URL)

You'll see the URL already exists.

Read more in the CRA docs.

If you are using C function fgetc then you should check a next character whether it is equal to the new line character or to EOF. For example

unsigned int count = 0;
while ( 1 )
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
      if ( c == EOF ) break;
   }
   else
   {
      ++count;
   }
}    

or maybe it would be better to rewrite the code using do-while loop. For example

unsigned int count = 0;
do
{
   int c = fgetc( FileStream );

   if ( c == EOF || c == '\n' )
   {
      printF( "The length of the line is %u\n", count );
      count = 0;
   }
   else
   {
      ++count;
   }
} while ( c != EOF );

Of course you need to insert your own processing of read xgaracters. It is only an example how you could use function fgetc to read lines of a file.

But if the program is written in C++ then it would be much better if you would use std::ifstream and std::string classes and function std::getline to read a whole line.

Although this thread dates back to 2014, the issue can still be current to many of us. Here is how I dealt with it in a jQuery 1.12 /PHP 5.6 context:

• jQuery sent its XHR request using only limited headers; only 'Origin' was sent.
• No preflight request was needed.
• The server only had to detect such a request, and add the "Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN'] header, after detecting that this was a cross-origin XHR.

PHP Code sample:

if (!empty($_SERVER['HTTP_ORIGIN'])) {
    // Uh oh, this XHR comes from outer space...
    // Use this opportunity to filter out referers that shouldn't be allowed to see this request
    if (!preg_match('@\.partner\.domain\.net$@'))
        die("End of the road if you're not my business partner.");

    // otherwise oblige
    header("Access-Control-Allow-Origin: " . $_SERVER['HTTP_ORIGIN']);
}
else {
    // local request, no need to send a specific header for CORS
}

In particular, don't add an exit; as no preflight is needed.

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

Use requests library to GET, POST, PUT or DELETE by hitting a REST API endpoint. Pass the rest api endpoint url in url, payload(dict) in data and header/metadata in headers

import requests, json

url = "bugs.python.org"

payload = {"number": 12524, 
           "type": "issue", 
           "action": "show"}

header = {"Content-type": "application/x-www-form-urlencoded",
          "Accept": "text/plain"} 

response_decoded_json = requests.post(url, data=payload, headers=header)
response_json = response_decoded_json.json()

print response_json

You don't have all digit characters in your string. So you have to split by space

QString Abcd = "123.5 Kb";
Abcd.split(" ")[0].toInt();    //convert the first part to Int
Abcd.split(" ")[0].toDouble(); //convert the first part to double
Abcd.split(" ")[0].toFloat();  //convert the first part to float

Update: I am updating an old answer. That was a straight forward answer to the specific question, with a strict assumption. However as noted by @DomTomCat in comments and @Mikhail in answer, In general one should always check whether the operation is successful or not. So using a boolean flag is necessary.

bool flag;
double v = Abcd.split(" ")[0].toDouble(&flag); 
if(flag){
  // use v
}

Also if you are taking that string as user input, then you should also be doubtful about whether the string is really splitable with space. If there is a possibility that the assumption may break then a regex verifier is more preferable. A regex like the following will extract the floating point value and the prefix character of 'b'. Then you can safely convert the captured strings to double.

([0-9]*\.?[0-9]+)\s+(\w[bB])

You can have an utility function like the following

You can delete the browser cache by setting these headers:

<?php
header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");
?>

If you prefer to resolve timestamps and dates conversions from and to UTC and local time without libraries like moment.js, take a look at the option below.

For applications that use UTC timestamps, you may need to show the date in the browser considering the local timezone and daylight savings when applicable. Editing a date that is in a different daylight savings time even though in the same timezone can be tricky.

The Number and Date extensions below allow you to show and get dates in the timezone of the timestamps. For example, lets say you are in Vancouver, if you are editing a date in July or in December, it can mean you are editing a date in PST or PDT.

I recommend you to check the Code Snippet down below to test this solution.

Conversions from milliseconds

Number.prototype.toLocalDate = function () {
    var value = new Date(this);

    value.setHours(value.getHours() + (value.getTimezoneOffset() / 60));

    return value;
};

Number.prototype.toUTCDate = function () {
    var value = new Date(this);

    value.setHours(value.getHours() - (value.getTimezoneOffset() / 60));

    return value;
};

Conversions from dates

Date.prototype.getUTCTime = function () {
    return this.getTime() - (this.getTimezoneOffset() * 60000);
};

Usage

// Adds the timezone and daylight savings if applicable
(1499670000000).toLocalDate();

// Eliminates the timezone and daylight savings if applicable
new Date(2017, 6, 10).getUTCTime();

(JavaScript) Using regexp, this checks for alphanumeric palindrome and disregards space and punctuation.

function palindrome(str) {
  str = str.match(/[A-Za-z0-9]/gi).join("").toLowerCase();
  //  (/[A-Za-z0-9]/gi) above makes str alphanumeric

  for(var i = 0; i < Math.floor(str.length/2); i++) { //only need to run for half the string length 
    if(str.charAt(i) !== str.charAt(str.length-i-1)) { // uses !== to compare characters one-by-one from the beginning and end
      return "Try again.";
    }
  }
  return "Palindrome!";
}
palindrome("A man, a plan, a canal. Panama.");
//palindrome("4_2 (: /-\ :) 2-4"); // This solution would also work on something like this.

As an addition to @C??? answer, make sure the title of the tooltip has not already been set manually in the HTML element. In my case, the span class for the tooltip already had a fixed tittle text, because of this my JQuery function $('[data-toggle="tooltip"]').prop('title', 'your new title'); did not work.

When I removed the title attribute in the HTML span class, the jQuery was working.

So:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top" title="this is my pre-set title text"></span>
</span>

Should becode:

<span class="showTooltip" data-target="#showTooltip" data-id="showTooltip">
      <span id="MyTooltip" class="fas fa-info-circle" data-toggle="tooltip" data-placement="top"></span>
</span>

I tried with one column of string values with nan.

To remove the nan and fill the empty string:

df.columnname.replace(np.nan,'',regex = True)

To remove the nan and fill some values:

df.columnname.replace(np.nan,'value',regex = True)

I tried df.iloc also. but it needs the index of the column. so you need to look into the table again. simply the above method reduced one step.

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

If your after a way for the hr to go straight from the left side of a screen to the right this is the code to use to ensure the view width isn't effected.

hr {
position: absolute;
left: 0;
right: 0;
}

Actually I think the LIMIT 10 would be issued to the database so slicing would not occur in Python but in the database.

See limiting-querysets for more information.

According to docs :

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();

This is a guess :)

Is it because the ID is a string? What happens if you change it to int?

I mean:

 public int Id { get; set; }

$query = "SELECT col1,col2,col3 FROM table WHERE id > 100"
$result = mysql_query($query);
if(mysql_num_rows($result)>0)
{
 while($row = mysql_fetch_array()) //here you can use many functions such as mysql_fetch_assoc() and other
 {
//It returns 1 row to your variable that becomes array and automatically go to the next result string
  Echo $row['col1']."|".Echo $row['col2']."|".Echo $row['col2'];
 }
}

You can make use of location service available in @angular/common and via this below code you can get the location or current URL

import { Component, OnInit } from '@angular/core';
import { Location } from '@angular/common';
import { Router } from '@angular/router';

@Component({
  selector: 'app-top-nav',
  templateUrl: './top-nav.component.html',
  styleUrls: ['./top-nav.component.scss']
})
export class TopNavComponent implements OnInit {

  route: string;

  constructor(location: Location, router: Router) {
    router.events.subscribe((val) => {
      if(location.path() != ''){
        this.route = location.path();
      } else {
        this.route = 'Home'
      }
    });
  }

  ngOnInit() {
  }

}

here is the reference link from where I have copied thing to get location for my project. https://github.com/elliotforbes/angular-2-admin/blob/master/src/app/common/top-nav/top-nav.component.ts

Tims answer seems to me as misleading. Especially when urllib2 does not return expected code. For example this Error will be fatal (believe or not - it is not uncommon one when downloading urls):

AttributeError: 'URLError' object has no attribute 'code'

Fast, but maybe not the best solution would be code using nested try/except block:

import urllib2
try:
    urllib2.urlopen("some url")
except urllib2.HTTPError, err:
    try:
        if err.code == 404:
            # Handle the error
        else:
            raise
    except:
        ...

More information to the topic of nested try/except blocks Are nested try/except blocks in python a good programming practice?

If you want to limit memory for jvm (not the heap size ) ulimit -v

Inserting date in sql

insert
into tablename (timestamp_value)
values ('dd-mm-yyyy hh-mm-ss AM');

If suppose we wanted to insert system date

insert
into tablename (timestamp_value)
values (sysdate);

With java 8, we can do like below to check if one list contains any element of other list

boolean var = lis1.stream().filter(element -> list2.contains(element)).findFirst().isPresent();

A quick way would be to modify the tux filename so that your move command will not match.

For example:

mv Tux.png .Tux.png

mv * ~/somefolder

mv .Tux.png Tux.png

The MySQL extension is the oldest of the three and was the original way that developers used to communicate with MySQL. This extension is now being deprecated in favor of the other two alternatives because of improvements made in newer releases of both PHP and MySQL.

• MySQLi is the 'improved' extension for working with MySQL databases. It takes advantage of features that are available in newer versions of the MySQL server, exposes both a function-oriented and an object-oriented interface to the developer and a does few other nifty things.

• PDO offers an API that consolidates most of the functionality that was previously spread across the major database access extensions, i.e. MySQL, PostgreSQL, SQLite, MSSQL, etc. The interface exposes high-level objects for the programmer to work with database connections, queries and result sets, and low-level drivers perform communication and resource handling with the database server. A lot of discussion and work is going into PDO and it’s considered the appropriate method of working with databases in modern, professional code.

In Google App Engine there is a webapp2 function called import_string. For more info see here:https://webapp-improved.appspot.com/api/webapp2.html

So,

import webapp2
my_class = webapp2.import_string('my_package.my_module.MyClass')

For example this is used in the webapp2.Route where you can either use a handler or a string.

If you're using Python 2.x on Windows you need to change your line open('test.csv', 'w') to open('test.csv', 'wb'). That is you should open the file as a binary file.

However, as stated by others, the file interface has changed in Python 3.x.

Use character classes: [ \t]

The quirky syntax using conditions on the target (described by Mads) is the only supported way to perform conditional execution in core ANT.

ANT is not a programming language and when things get complicated I choose to embed a script within my build as follows:

<target name="prepare-copy" description="copy file based on condition">
    <groovy>
        if (properties["some.condition"] == "true") {
            ant.copy(file:"${properties["some.dir"]}/true", todir:".")
        }
    </groovy>
</target>

ANT supports several languages (See script task), my preference is Groovy because of it's terse syntax and because it plays so well with the build.

Apologies, David I am not a fan of ant-contrib.

It seems like you have it worked out, but for others looking for this answer, an easy way to do this is by printing to stderr. You can do that like this:

from __future__ import print_function # In python 2.7
import sys

@app.route('/button/')
def button_clicked():
    print('Hello world!', file=sys.stderr)
    return redirect('/')

Flask will display things printed to stderr in the console. For other ways of printing to stderr, see this stackoverflow post

just import requests and use from json() method :

source = requests.get("url").json()
print(source)

OR you can use this :

import json,urllib.request
data = urllib.request.urlopen("url").read()
output = json.loads(data)
print (output)

The following steps solved blank white screen problem on my Laravel 5.

• Go to your Laravel root folder
• Give write permission to bootstrap/cache and storage directories

sudo chmod -R 777 bootstrap/cache storage

• Rename .env.example to .env
• Generate application key with the following command in terminal/command-prompt from Laravel root:

php artisan key:generate

This will generate the encryption key and update the value of APP_KEY in .env file

This should solve the problem.

If the problem still exists, then update config/app.php with the new key generated from the above artisan key generate command:

'key' => env('APP_KEY', 'SomeRandomString'),

to

'key' => env('APP_KEY', 'KEY_GENERATED_FROM_ABOVE_COMMAND'),

Try to include length > 0 as well.

column1 is not NULL AND column1 <> '' AND length(column1) > 0 

Depending on which property you are interested in:

alert(product.ProductName);
alert(product.UnitPrice);
alert(product.Stock);

If you want to get advantage of your local machine timezone you can use myDateTime.ToUniversalTime() to get the UTC time from your local time or myDateTime.ToLocalTime() to convert the UTC time to the local machine's time.

// convert UTC time from the database to the machine's time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var localTime = databaseUtcTime.ToLocalTime();

// convert local time to UTC for database save
var databaseUtcTime = localTime.ToUniversalTime();

If you need to convert time from/to other timezones, you may use TimeZoneInfo.ConvertTime() or TimeZoneInfo.ConvertTimeFromUtc().

// convert UTC time from the database to japanese time
DateTime databaseUtcTime = new DateTime(2011,6,5,10,15,00);
var japaneseTimeZone = TimeZoneInfo.FindSystemTimeZoneById("Tokyo Standard Time");
var japaneseTime = TimeZoneInfo.ConvertTimeFromUtc(databaseUtcTime, japaneseTimeZone);

// convert japanese time to UTC for database save
var databaseUtcTime = TimeZoneInfo.ConvertTimeToUtc(japaneseTime, japaneseTimeZone);

Directly getting first element from an array will potentially cause exception if the path is not found. So calling first and then unwrap is the better solution

if let documentsPathString = NSSearchPathForDirectoriesInDomains(.documentDirectory, .userDomainMask, true).first {
    //This gives you the string formed path
}

if let documentsPathURL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first {
    //This gives you the URL of the path
}

A simple JavaScript function will do the job.

function ClearFields() {

     document.getElementById("textfield1").value = "";
     document.getElementById("textfield2").value = "";
}

And just have your button call it:

<button type="button" onclick="ClearFields();">Clear</button>

My personal experience is that shortcuts.xml is overwritten with the initially loaded + later recorded macros and settings when Notepad++ exits. So you can't use Notepad++ itself for editing this file.

Close Notepad++, edit shortcuts.xml by another tool, save it and restart Notepad++.

In some systems one have to specify:

import os
os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"]=""  # or even "-1"

BEFORE importing tensorflow.

Use the .Clear method.

Sheets("Test").Range("A1:C3").Clear

You can import modules but not text files. If you want to print the content do the following:

Open a text file for reading:

f = open('words.txt', 'r')

Store content in a variable:

content = f.read()

Print content of this file:

print(content)

After you're done close a file:

f.close()

PHPSESSID reveals you are using PHP. If you don't want this you can easily change the name using the session.name in your php.ini file or using the session_name() function.

An alternative to theme_classic() is the theme that comes with the cowplot package, theme_cowplot() (loaded automatically with the package). It looks similar to theme_classic(), with a few subtle differences. Most importantly, the default label sizes are larger, so the resulting figures can be used in publications without further modifications needed (in particular if you save them with save_plot() instead of ggsave()). Also, the background is transparent, not white, which may be useful if you want to edit the figure in illustrator. Finally, faceted plots look better, in my opinion.

Example:

library(cowplot)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p <- ggplot(df, aes(x = a, y = b)) + geom_point()
save_plot('plot.png', p) # alternative to ggsave, with default settings that work well with the theme

For 500 records efficiency is probably not an issue, but if you have millions of records then it can be advantageous to use a WHERE clause to select the next page:

SELECT *
FROM yourtable
WHERE id > 234374
ORDER BY id
LIMIT 20

The "234374" here is the id of the last record from the prevous page you viewed.

This will enable an index on id to be used to find the first record. If you use LIMIT offset, 20 you could find that it gets slower and slower as you page towards the end. As I said, it probably won't matter if you have only 200 records, but it can make a difference with larger result sets.

Another advantage of this approach is that if the data changes between the calls you won't miss records or get a repeated record. This is because adding or removing a row means that the offset of all the rows after it changes. In your case it's probably not important - I guess your pool of adverts doesn't change too often and anyway no-one would notice if they get the same ad twice in a row - but if you're looking for the "best way" then this is another thing to keep in mind when choosing which approach to use.

If you do wish to use LIMIT with an offset (and this is necessary if a user navigates directly to page 10000 instead of paging through pages one by one) then you could read this article about late row lookups to improve performance of LIMIT with a large offset.

Did you try WKHTMLTOPDF?

It's a simple shell utility, an open source implementation of WebKit. Both are free.

We've set a small tutorial here

EDIT( 2017 ):

If it was to build something today, I wouldn't go that route anymore.
But would use http://pdfkit.org/ instead.
Probably stripping it of all its nodejs dependencies, to run in the browser.

Alternatively,

<style type="text/css">
#example {
    display: block;
    width: 30px;
    height: 10px;
    background: url(../images/example.png) no-repeat;
    text-indent: -9999px;
}
</style>

<a href="http://www.example.com" id="example">See an example!</a>

More wordy, but it may benefit SEO, and it will look like nice simple text with CSS disabled.

I had the same problem because my "Dynamic Web Project" had no reference to the installed server i wanted to use and therefore had no reference to the Servlet API the server provides.

Following steps solved it without adding an extra Servlet-API to the Java Build Path (Eclipse version: Luna):

• Right click on your "Dynamic Web Project"
• Select Properties
• Select Project Facets in the list on the left side of the "Properties" wizard
• On the right side of the wizard you should see a tab named Runtimes. Select the Runtime tab and check the server you want to run the servlet.

Edit: if there is no server listed you can create a new one on the Runtimes tab

After this

Two things to do:

Project Settings > Project compiler output > Set it as "Project path(You actual project's path)”+”\out”.

Project Settings > Module > Path > Choose "Inherit project compile path""

This is an elaborate version, to help you understand

function setVolatileBehavior(elem, onColor, offColor, promptText){ //changed spelling of function name to be the same as name used at invocation below
elem.addEventListener("change", function(){
    if (document.activeElement == elem && elem.value==promptText){
        elem.value='';
        elem.style.color = onColor;
    }
    else if (elem.value==''){
        elem.value=promptText;
        elem.style.color = offColor;
    }
});
elem.addEventListener("blur", function(){
    if (document.activeElement == elem && elem.value==promptText){
        elem.value='';
        elem.style.color = onColor;
    }
    else if (elem.value==''){
        elem.value=promptText;
        elem.style.color = offColor;
    }
});
elem.addEventListener("focus", function(){
    if (document.activeElement == elem && elem.value==promptText){
        elem.value='';
        elem.style.color = onColor;
    }
    else if (elem.value==''){
        elem.value=promptText;
        elem.style.color = offColor;

});
elem.value=promptText;
elem.style.color=offColor;
}

Use like this:

setVolatileBehavior(document.getElementById('yourElementID'),'black','gray','Name');

The endroid/QrCode library is easy to use, well maintained, and can be installed using composer. There is also a bundle to use directly with Symfony.

Installing :

$ composer require endroid/qrcode

Usage :

<?php

use Endroid\QrCode\QrCode;

$qrCode = new QrCode();
$qrCode
    ->setText('Life is too short to be generating QR codes')
    ->setSize(300)
    ->setPadding(10)
    ->setErrorCorrection('high')
    ->setForegroundColor(array('r' => 0, 'g' => 0, 'b' => 0, 'a' => 0))
    ->setBackgroundColor(array('r' => 255, 'g' => 255, 'b' => 255, 'a' => 0))
    ->setLabel('Scan the code')
    ->setLabelFontSize(16)
    ->setImageType(QrCode::IMAGE_TYPE_PNG)
;

// now we can directly output the qrcode
header('Content-Type: '.$qrCode->getContentType());
$qrCode->render();

// or create a response object
$response = new Response($qrCode->get(), 200, array('Content-Type' => $qrCode->getContentType()));

Just to provide the os.stat version (python 2):

import os, stat, errno
def CheckIsDir(directory):
  try:
    return stat.S_ISDIR(os.stat(directory).st_mode)
  except OSError, e:
    if e.errno == errno.ENOENT:
      return False
    raise

Note that the ansible command doesn't collect facts, but the ansible-playbook command does. When running ansible -m setup, the setup module happens to run the fact collection so you get the facts, but running ansible -m command does not. Therefore the facts aren't available. This is why the other answers include playbook YAML files and indicate the lookup works.

Make sure you are loading those modules (myApp.services and myApp.directives) as dependencies of your main app module, like this:

angular.module('myApp', ['myApp.directives', 'myApp.services']);

The @media query specifically for 'phones' is..

@media (max-width: 480px) { ... }

But, you may want to remove the padding/margin for any smaller screen sizes. By default, Bootstrap adjusts margins/padding to the body, container and navbars at 978px.

Here are some queries that have worked (in most cases) for me:

@media (max-width: 978px) {
    .container {
      padding:0;
      margin:0;
    }

    body {
      padding:0;
    }

    .navbar-fixed-top, .navbar-fixed-bottom, .navbar-static-top {
      margin-left: 0;
      margin-right: 0;
      margin-bottom:0;
    }
}

Demo

Update for Bootstrap 4

Use the new responsive spacing utils which let you set padding/margins for different screen widths (breakpoints): https://stackoverflow.com/a/43208888/171456

Although you could certainly use the compareTo method on an Integer instance, it's not clear when reading the code, so you should probably avoid doing so.

Java allows you to use autoboxing (see http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html) to compare directly with an int, so you can do:

if (count > 0) { }

And the Integer instance count gets automatically converted to an int for the comparison.

If you're having trouble understanding this, check out the link above, or imagine it's doing this:

if (count.intValue() > 0) { }

The code below will write the 4 unicode chars (represented by decimals) for the word "be" in Japanese. Yes, the verb "be" in Japanese has 4 chars! The value of characters is in decimal and it has been read into an array of String[] -- using split for instance. If you have Octal or Hex, parseInt take a radix as well.

// pseudo code
// 1. init the String[] containing the 4 unicodes in decima :: intsInStrs 
// 2. allocate the proper number of character pairs :: c2s
// 3. Using Integer.parseInt (... with radix or not) get the right int value
// 4. place it in the correct location of in the array of character pairs
// 5. convert c2s[] to String
// 6. print 

String[] intsInStrs = {"12354", "12426", "12414", "12377"}; // 1.
char [] c2s = new char [intsInStrs.length * 2];  // 2.  two chars per unicode

int ii = 0;
for (String intString : intsInStrs) {
    // 3. NB ii*2 because the 16 bit value of Unicode is written in 2 chars
    Character.toChars(Integer.parseInt(intsInStrs[ii]), c2s, ii * 2 ); // 3 + 4
    ++ii; // advance to the next char
}

String symbols = new String(c2s);  // 5.
System.out.println("\nLooooonger code point: " + symbols); // 6.
// I tested it in Eclipse and Java 7 and it works.  Enjoy

.bash_profile is loaded for a "login shell". I am not sure what that would be on OS X, but on Linux that is either X11 or a virtual terminal.

.bashrc is loaded every time you run Bash. That is where you should put stuff you want loaded whenever you open a new Terminal.app window.

I personally put everything in .bashrc so that I don't have to restart the application for changes to take effect.

To summarize what has been commented in other answers:

//path = @"C:\Temp\Bar\Foo\Test.txt";
Directory.CreateDirectory(Path.GetDirectoryName(path));

Directory.CreateDirectory will create the directories recursively and if the directory already exist it will return without an error.

If there happened to be a file Foo at C:\Temp\Bar\Foo an exception will be thrown.

It's possible but not all that easy, to create a hybrid native/managed assembly in C#. Were you using C++ instead it'd be a lot easier, as the Visual C++ compiler can create hybrid assemblies as easily as anything else.

Unless you have a strict requirement to produce a hybrid assembly, I'd agree with MusiGenesis that this isn't really worth the trouble to do with C#. If you need to do it, perhaps look at moving to C++/CLI instead.

Following changes you have to make that's it(change architecture into armv7 and remove others) :-

you can set it in the main index.php

    define('ENVIRONMENT', 'development');
/*
 *---------------------------------------------------------------
 * ERROR REPORTING
 *---------------------------------------------------------------
 *
 * Different environments will require different levels of error reporting.
 * By default development will show errors but testing and live will hide them.
 */

if (defined('ENVIRONMENT'))
{
    switch (ENVIRONMENT)
    {
        case 'development':
            error_reporting(E_ALL);
        break;

    case 'testing':
    case 'production':
        error_reporting(0);
    break;

    default:
        exit('The application environment is not set correctly.');
}
}

We can do it with another approach too, Like first of all get the hash value from js and call the ajax using that parameter and can do whatever we want

I spent a good amount of time trying to work this out today, and couldn't get things working using line-height or vertical-align. The easiest solution I was able to find was to set the <a/> to be relatively positioned so it would contain absolutes, and the :after to be positioned absolutely taking it out of the flow.

a{
    position:relative;
    padding-right:18px;
}
a:after{
    position:absolute;
    content:url(image.png);
}

The after image seemed to automatically center in that case, at least under Firefox/Chrome. Such may be a bit sloppier for browsers not supporting :after, due to the excess spacing on the <a/>.

If you want to export your last n amount of records into a file, you can run the following:

mysqldump -u user -p -h localhost --where "1=1 ORDER BY id DESC LIMIT 100" database table > export_file.sql

The above will save the last 100 records into export_file.sql, assuming the table you're exporting from has an auto-incremented id column.

You will need to alter the user, localhost, database and table values. You may optionally alter the id column and export file name.

just put a breakpoint on the last curly bracket of main.

    int main () {
       //...your code...
       return 0;
    } //<- breakpoint here

it works for me, no need to run without debugging. It also executes destructors before hitting the breakpoint so you can check any messages print on these destructors if you have any.

Test with [char]9, such as:

$Tab = [char]9
Write-Output "$Tab hello"

Output:

     hello

I enclosed C++ code for grabbing frames. It requires OpenCV version 2.0 or higher. The code uses cv::mat structure which is preferred to old IplImage structure.

#include "cv.h"
#include "highgui.h"
#include <iostream>

int main(int, char**) {
    cv::VideoCapture vcap;
    cv::Mat image;

    const std::string videoStreamAddress = "rtsp://cam_address:554/live.sdp"; 
    /* it may be an address of an mjpeg stream, 
    e.g. "http://user:pass@cam_address:8081/cgi/mjpg/mjpg.cgi?.mjpg" */

    //open the video stream and make sure it's opened
    if(!vcap.open(videoStreamAddress)) {
        std::cout << "Error opening video stream or file" << std::endl;
        return -1;
    }

    //Create output window for displaying frames. 
    //It's important to create this window outside of the `for` loop
    //Otherwise this window will be created automatically each time you call
    //`imshow(...)`, which is very inefficient. 
    cv::namedWindow("Output Window");

    for(;;) {
        if(!vcap.read(image)) {
            std::cout << "No frame" << std::endl;
            cv::waitKey();
        }
        cv::imshow("Output Window", image);
        if(cv::waitKey(1) >= 0) break;
    }   
}

Update You can grab frames from H.264 RTSP streams. Look up your camera API for details to get the URL command. For example, for an Axis network camera the URL address might be:

// H.264 stream RTSP address, where 10.10.10.10 is an IP address 
// and 554 is the port number
rtsp://10.10.10.10:554/axis-media/media.amp

// if the camera is password protected
rtsp://username:[email protected]:554/axis-media/media.amp

this is what i did

first execute create database x. x is the name of your old database eg the name of the mdf.

Then open sql sever configration and stop the sql sever.

There after browse to the location of your new created database it should be under program file, in my case is

C:\Program Files\Microsoft SQL Server\MSSQL14.MSSQL\MSSQL\DATA

and repleace the new created mdf and Idf with the old files/database.

then simply restart the sql server and walla :)

Shorter sample for json.net library.

using Newtonsoft.Json;

private static string format_json(string json)
{
    dynamic parsedJson = JsonConvert.DeserializeObject(json);
    return JsonConvert.SerializeObject(parsedJson, Formatting.Indented);
}

PS: You can wrap the formatted json text with tag to print as it is on the html page.

FYI this kind of code works (you can find it ugly, it is your right :) ) :

def list = null
list.each { println it }
soSomething()

In other words, this code has null/empty checks both useless:

if (members && !members.empty) {
    members.each { doAnotherThing it }
}

def doAnotherThing(def member) {
  // Some work
}

There are several problems with your code:

1. WordList is not defined anywhere. You should define it before you use it.
2. You can't just write code outside a function like this. You need to put it in a function.
3. You need to #include <string> before you can use the string class and iostream before you use cout or endl.
4. string, cout and endl live in the std namespace, so you can not access them without prefixing them with std:: unless you use the using directive to bring them into scope first.

The most basic way you can do this in SelectedIndexChanged events of DropDownLists. Check this code..

    <asp:DropDownList ID="DropDownList1" runat="server" onselectedindexchanged="DropDownList1_SelectedIndexChanged" Width="224px"
        AutoPostBack="True" AppendDataBoundItems="true">
    <asp:DropDownList ID="DropDownList2" runat="server"
        onselectedindexchanged="DropDownList2_SelectedIndexChanged">
    </asp:DropDownList> 


protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList2

}
protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e)
{
    //Load DropDownList3
}

The divs are treated as inline-elements. Just as a space or line-break between two spans would create a gap, it does between inline-blocks. You could either give them a negative margin or set word-spacing: -1; on the surrounding container.

Using routerLinkActive is good in simple cases, when there is a link and you want to apply some classes. But in more complex cases where you may not have a routerLink or where you need something more you can create and use a pipe:

@Pipe({
    name: "isRouteActive",
    pure: false
})
export class IsRouteActivePipe implements PipeTransform {

    constructor(private router: Router,
                private activatedRoute: ActivatedRoute) {
    }

    transform(route: any[], options?: { queryParams?: any[], fragment?: any, exact?: boolean }) {
        if (!options) options = {};
        if (options.exact === undefined) options.exact = true;

        const currentUrlTree = this.router.parseUrl(this.router.url);
        const urlTree = this.router.createUrlTree(route, {
            relativeTo: this.activatedRoute,
            queryParams: options.queryParams,
            fragment: options.fragment
        });
        return containsTree(currentUrlTree, urlTree, options.exact);
    }
}

then:

<div *ngIf="['/some-route'] | isRouteActive">...</div>

and don't forget to include pipe in the pipes dependencies ;)

Is there a particular reason you have chosen XML config files? I have done XML configs in the past, and they have often turned out to be more of a headache than anything else.

I guess the real question is whether using something like the Preferences API might work better in your situation.

Reasons to use the Preferences API over a roll-your-own XML solution:

• Avoids typical XML ugliness (DocumentFactory, etc), along with avoiding 3rd party libraries to provide the XML backend

• Built in support for default values (no special handling required for missing/corrupt/invalid entries)

• No need to sanitize values for XML storage (CDATA wrapping, etc)

• Guaranteed status of the backing store (no need to constantly write XML out to disk)

• Backing store is configurable (file on disk, LDAP, etc.)

• Multi-threaded access to all preferences for free

This resolved the issue on Windows 10 after the last update

go Control Panel ->> Programs ->> Programs and Features ->> Turn Windows features on or off ->> Internet Information Services

But based on previous response it doesn't work unless checking all these options as on pic below

ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)

modify list of host names for your system:

C:\Windows\System32\drivers\etc\hosts

Make sure that you have the following entry:

127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem

(you may need to change modify permission to modify this file)

This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.

You're most likely looking at using a flash/silverlight/activeX control. The <input type="file" /> control doesn't handle that.

If you don't mind the user selecting a file as a means to getting its directory, you may be able to bind to that control's change event then strip the filename portion and save the path somewhere--but that's about as good as it gets.

Keep in mind that webpages are designed to interact with servers. Nothing about providing a local directory to a remote server is "typical" (a server can't access it so why ask for it?); however files are a means to selectively passing information.

Have you tried somethig like this?

.showme{display: none;}
.showhim:hover .showme{display : block;}
.hideme{display:block;}
.showhim:hover .hideme{display:none;}

<div class="showhim">HOVER ME
  <div class="showme">hai</div>
  <div class="hideme">bye</div>
</div>

I dont know any reason why it shouldn't be possible.

Your class JSON_result does not match your JSON string. Note how the object JSON_result is going to represent is wrapped in another property named "Venue".

So either create a class for that, e.g.:

Public Class Container
    Public Venue As JSON_result
End Class

Public Class JSON_result
    Public ID As Integer
    Public Name As String
    Public NameWithTown As String
    Public NameWithDestination As String
    Public ListingType As String
End Class

Dim obj = JsonConvert.DeserializeObject(Of Container)(...your_json...)

or change your JSON string to

{
    "ID": 3145,
    "Name": "Big Venue, Clapton",
    "NameWithTown": "Big Venue, Clapton, London",
    "NameWithDestination": "Big Venue, Clapton, London",
    "ListingType": "A",
    "Address": {
        "Address1": "Clapton Raod",
        "Address2": "",
        "Town": "Clapton",
        "County": "Greater London",
        "Postcode": "PO1 1ST",
        "Country": "United Kingdom",
        "Region": "Europe"
    },
    "ResponseStatus": {
        "ErrorCode": "200",
        "Message": "OK"
    }
}

or use e.g. a ContractResolver to parse the JSON string.

UPDATE some_table SET some_field = REPLACE(some_field, '&lt;', '<')

The -m switch of PuTTY takes a path to a script file as an argument, not a command.

Reference: https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-m

So you have to save your command (command_run) to a plain text file (e.g. c:\path\command.txt) and pass that to PuTTY:

putty.exe -ssh user@host -pw password -m c:\path\command.txt

Though note that you should use Plink (a command-line connection tool from PuTTY suite). It's a console application, so you can redirect its output to a file (what you cannot do with PuTTY).

A command-line syntax is identical, an output redirection added:

plink.exe -ssh user@host -pw password -m c:\path\command.txt > output.txt

See Using the command-line connection tool Plink.

And with Plink, you can actually provide the command directly on its command-line:

plink.exe -ssh user@host -pw password command > output.txt

Your @POST method should be accepting a JSON object instead of a string. Jersey uses JAXB to support marshaling and unmarshaling JSON objects (see the jersey docs for details). Create a class like:

@XmlRootElement
public class MyJaxBean {
    @XmlElement public String param1;
    @XmlElement public String param2;
}

Then your @POST method would look like the following:

@POST @Consumes("application/json")
@Path("/create")
public void create(final MyJaxBean input) {
    System.out.println("param1 = " + input.param1);
    System.out.println("param2 = " + input.param2);
}

This method expects to receive JSON object as the body of the HTTP POST. JAX-RS passes the content body of the HTTP message as an unannotated parameter -- input in this case. The actual message would look something like:

POST /create HTTP/1.1
Content-Type: application/json
Content-Length: 35
Host: www.example.com

{"param1":"hello","param2":"world"}

Using JSON in this way is quite common for obvious reasons. However, if you are generating or consuming it in something other than JavaScript, then you do have to be careful to properly escape the data. In JAX-RS, you would use a MessageBodyReader and MessageBodyWriter to implement this. I believe that Jersey already has implementations for the required types (e.g., Java primitives and JAXB wrapped classes) as well as for JSON. JAX-RS supports a number of other methods for passing data. These don't require the creation of a new class since the data is passed using simple argument passing.

HTML <FORM>

The parameters would be annotated using @FormParam:

@POST
@Path("/create")
public void create(@FormParam("param1") String param1,
                   @FormParam("param2") String param2) {
    ...
}

The browser will encode the form using "application/x-www-form-urlencoded". The JAX-RS runtime will take care of decoding the body and passing it to the method. Here's what you should see on the wire:

POST /create HTTP/1.1
Host: www.example.com
Content-Type: application/x-www-form-urlencoded;charset=UTF-8
Content-Length: 25

param1=hello&param2=world

The content is URL encoded in this case.

If you do not know the names of the FormParam's you can do the following:

@POST @Consumes("application/x-www-form-urlencoded")
@Path("/create")
public void create(final MultivaluedMap<String, String> formParams) {
    ...
}

HTTP Headers

You can using the @HeaderParam annotation if you want to pass parameters via HTTP headers:

@POST
@Path("/create")
public void create(@HeaderParam("param1") String param1,
                   @HeaderParam("param2") String param2) {
    ...
}

Here's what the HTTP message would look like. Note that this POST does not have a body.

POST /create HTTP/1.1
Content-Length: 0
Host: www.example.com
param1: hello
param2: world

I wouldn't use this method for generalized parameter passing. It is really handy if you need to access the value of a particular HTTP header though.

HTTP Query Parameters

This method is primarily used with HTTP GETs but it is equally applicable to POSTs. It uses the @QueryParam annotation.

@POST
@Path("/create")
public void create(@QueryParam("param1") String param1,
                   @QueryParam("param2") String param2) {
    ...
}

Like the previous technique, passing parameters via the query string does not require a message body. Here's the HTTP message:

POST /create?param1=hello&param2=world HTTP/1.1
Content-Length: 0
Host: www.example.com

You do have to be particularly careful to properly encode query parameters on the client side. Using query parameters can be problematic due to URL length restrictions enforced by some proxies as well as problems associated with encoding them.

HTTP Path Parameters

Path parameters are similar to query parameters except that they are embedded in the HTTP resource path. This method seems to be in favor today. There are impacts with respect to HTTP caching since the path is what really defines the HTTP resource. The code looks a little different than the others since the @Path annotation is modified and it uses @PathParam:

@POST
@Path("/create/{param1}/{param2}")
public void create(@PathParam("param1") String param1,
                   @PathParam("param2") String param2) {
    ...
}

The message is similar to the query parameter version except that the names of the parameters are not included anywhere in the message.

POST /create/hello/world HTTP/1.1
Content-Length: 0
Host: www.example.com

This method shares the same encoding woes that the query parameter version. Path segments are encoded differently so you do have to be careful there as well.

As you can see, there are pros and cons to each method. The choice is usually decided by your clients. If you are serving FORM-based HTML pages, then use @FormParam. If your clients are JavaScript+HTML5-based, then you will probably want to use JAXB-based serialization and JSON objects. The MessageBodyReader/Writer implementations should take care of the necessary escaping for you so that is one fewer thing that can go wrong. If your client is Java based but does not have a good XML processor (e.g., Android), then I would probably use FORM encoding since a content body is easier to generate and encode properly than URLs are. Hopefully this mini-wiki entry sheds some light on the various methods that JAX-RS supports.

Note: in the interest of full disclosure, I haven't actually used this feature of Jersey yet. We were tinkering with it since we have a number of JAXB+JAX-RS applications deployed and are moving into the mobile client space. JSON is a much better fit that XML on HTML5 or jQuery-based solutions.

Your code works, but the fadeIn doesn't, because it's already visible. I think the effect you want to achieve is: fadeOut → load → fadeIn:

var auto_refresh = setInterval(function () {
    $('.View').fadeOut('slow', function() {
        $(this).load('/echo/json/', function() {
            $(this).fadeIn('slow');
        });
    });
}, 15000); // refresh every 15000 milliseconds

Try it here: http://jsfiddle.net/kelunik/3qfNn/1/

Additional notice: As Khanh TO mentioned, you may need to get rid of the browser's internal cache. You can do so using $.ajax and $.ajaxSetup ({ cache: false }); or the random-hack, he mentioned.

cp -r ./SourceFolder ./DestFolder

The best way to accomplish this is to use the \r character

Just try the below code:

import time
for n in range(500):
  print(n, end='\r')
  time.sleep(0.01)
print()  # start new line so most recently printed number stays

if you want to exit from node js application then write

process.exit(1)

One of the coolest benefits of using something like Spring is that you don't have to wire your objects together. Zeus's head splits open and your classes appear, fully formed with all of their dependencies created and wired-in, as needed. It's magical and fantastic.

The more you say ClassINeed classINeed = (ClassINeed)ApplicationContext.getBean("classINeed");, the less magic you're getting. Less code is almost always better. If your class really needed a ClassINeed bean, why didn't you just wire it in?

That said, something obviously needs to create the first object. There's nothing wrong with your main method acquiring a bean or two via getBean(), but you should avoid it because whenever you're using it, you're not really using all of the magic of Spring.

There are JDK versions available from the base CentOS repositories. Depending on your version of CentOS, and the JDK you want to install, the following as root should give you what you want:

OpenJDK Runtime Environment (Java SE 6)

yum install java-1.6.0-openjdk

OpenJDK Runtime Environment (Java SE 7)

yum install java-1.7.0-openjdk

OpenJDK Development Environment (Java SE 7)

yum install java-1.7.0-openjdk-devel

OpenJDK Development Environment (Java SE 6)

yum install java-1.6.0-openjdk-devel

Update for Java 8

In CentOS 6.6 or later, Java 8 is available. Similar to 6 and 7 above, the packages are as follows:

OpenJDK Runtime Environment (Java SE 8)

yum install java-1.8.0-openjdk

OpenJDK Development Environment (Java SE 8)

yum install java-1.8.0-openjdk-devel

There's also a 'headless' JRE package that is the same as the above JRE, except it doesn't contain audio/video support. This can be used for a slightly more minimal installation:

OpenJDK Runtime Environment - Headless (Java SE 8)

yum install java-1.8.0-openjdk-headless

There is a NuGet package named StrongNamer by Daniel Plaisted that seems to do the trick.

Is the simplest solution that I've found so far.

There are also a number of other NuGet packages to fix the strong naming problem such as Brutal.Dev.StrongNameSigner by Werner van Deventer, but I have not tested that one or any of the others.

If you only have directories in the folder and no files this does it:

ls | wc -l

The standard Java classloader is a stickler for directory structure. Each entry in the classpath is a directory or jar file (or zip file, really), which it then searches for the given class file. For example, if your classpath is ".;my.jar", it will search for com.example.Foo in the following locations:

./com/example/
my.jar:/com/example/

That is, it will look in the subdirectory that has the 'modified name' of the package, where '.' is replaced with the file separator.

Also, it is noteworthy that you cannot nest .jar files.

You have to make sure that "Dependency Management" is enabled. To do so, right click on the project name, go to the "Gradle" sub-menu and click on "Enable Dependency Management". Once you do that, Gradle should load all the dependencies for you.

it's the same as think the next:

"starting with i = 0, while i is less than 8, and adding one to i at the end of the parenthesis, do the instructions between brackets"

It's also the same as:

while( i < 8 )
{
    // instrucctions like:
    Console.WriteLine(i);
    i++;
}

the For sentences is a basis of coding, and it's as useful as necessary its understanding.

It's the way to repeat n-times the same instrucction, or browse ( or do something with each element) an array

Quick and in some cases error-prone solution:

Find Regexp: (?sm)(.*?)([^\n]*\b(class|interface|enum)\b.*)

Replace: $1/**\n * \n * @author <a href="mailto:[email protected]">John Smith</a>\n */\n$2

This will add the header to the first encountered class/interface/enum in the file. Class should have no existing header yet.

None of those answers include a counter...

#!/bin/bash
## declare an array variable
declare -a array=("one" "two" "three")

# get length of an array
arraylength=${#array[@]}

# use for loop to read all values and indexes
for (( i=1; i<${arraylength}+1; i++ ));
do
  echo $i " / " ${arraylength} " : " ${array[$i-1]}
done

Output:

1  /  3  :  one
2  /  3  :  two
3  /  3  :  three

Pure javascript solution with scrollIntoView() function:

document.getElementById('title1').scrollIntoView({block: 'start', behavior: 'smooth'});

<h2 id="title1">Some title</h2>

P.S. 'smooth' parameter now works from Chrome 61 as julien_c mentioned in the comments.

Using Vue 1.x, use the special variable $index like so:

<li v-for="catalog in catalogs">this index : {{$index + 1}}</li>

alternatively, you can specify an alias as a first argument for v-for directive like so:

<li v-for="(itemObjKey, catalog) in catalogs">
    this index : {{itemObjKey + 1}}
</li>

See : Vue 1.x guide

Using Vue 2.x, v-for provides a second optional argument referencing the index of the current item, you can add 1 to it in your mustache template as seen before:

<li v-for="(catalog, itemObjKey) in catalogs">
    this index : {{itemObjKey + 1}}
</li>

See: Vue 2.x guide

Eliminating the parentheses in the v-for syntax also works fine hence:

<li v-for="catalog, itemObjKey in catalogs">
    this index : {{itemObjKey + 1}}
</li>

Hope that helps.

If you prefer to use the simplest possible solution to a problem, an alternative to RedirectMatch is, the more basic, Redirect directive.

It does not use pattern matching and so is more explicit and easier for others to understand.

i.e

<IfModule mod_alias.c>

#Repoint old contact page to new contact page:
Redirect 301 /contact.php http://example.com/contact-us.php

</IfModule>

Query strings should be carried over because the docs say:

Additional path information beyond the matched URL-path will be appended to the target URL.

I don't think there's any reason to add this function to JQuery's namespace. Why not just define the method by itself:

function showMessage(msg) {
   alert(msg);
};

<input type="button" value="ahaha" onclick="showMessage('msg');" />

UPDATE: With a small change to how your method is defined I can get it to work:

<html>
<head>
 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
 <script language="javascript">
    // define the function within the global scope
    $.fn.MessageBox = function(msg) {
        alert(msg);
    };

    // or, if you want to encapsulate variables within the plugin
    (function($) {
        $.fn.MessageBoxScoped = function(msg) {
            alert(msg);
        };
    })(jQuery); //<-- make sure you pass jQuery into the $ parameter
 </script>
</head>
<body>
 <div class="Title">Welcome!</div>
 <input type="button" value="ahaha" id="test" onClick="$(this).MessageBox('msg');" />
</body>
</html>

awk one-liner:

awk '/abc/,/efg/' [file-with-content]

Ian Mackinnon found the answer, but it's better with xargs:

git ls-files --deleted -z | xargs -r0 git rm

As a git alias:

git config --global alias.rm-deleted '!git ls-files --deleted -z | xargs -r0 git rm'

This uses xargs with NUL termination (the only byte guarranteed not to appear in a path) and the option to not run git rm if the file list is empty.

This syntax is also fish compatible.

I got this error too, but my problem was that I was using an older version of GACUTIL.EXE.

Once I had the correct GACUTIL for the latest .NET version installed, it worked fine.

The error is misleading because it makes it look like it's the DLL you're trying to register that incorrect.

If you know the arrays are of the same size it is provably faster to sort then compare

Arrays.sort(array1)
Arrays.sort(array2)
return Arrays.equals(array1, array2)

If you do not want to change the order of the data in the arrays then do a System.arraycopy first.

I would recommend using a Double not a double as your type then you check against null.

CTRL+SHIFT+ENTER, ARRAY FORMULA EXCEL 2016 MAC. So I arrive late into the game, but maybe someone else will. This almost drove me nuts. No matter what I searched for in Google I came up empty. Whatever I tried, no solution seemed to be in sight. Switched to Excel 2016 quite some time ago and today I needed to do some array formulas. Also sitting on a MacBook Pro 15 Touch Bar 2016. Not that it really matters, but still, since the solution was published on Youtube in 2013. The reason why, for me anyway, nothing worked, is in the Mac OS, the control key by default, for me anyway, is set to manage Mission control, which, at least for me, disabled the control button in Excel. In order to enable the key to actually control functions in Excel, you need to go to System preferences > Mission Control, and disable shortcuts for Mission control. So, let's see how long this solution will last. Probably be back to square one after the coffee break. Have a good one!

You can add setenv.sh in the the bin directory with:

export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")

and it will dynamically change when you update your packages.

Ctrl-m i interrupts the kernel. (that is, the sole letter i after Ctrl-m)

According to this answer, I twice works as well.

There isn't any easy way to calculate this. But some people have tried to get some good answers:

The accepted answer is correct but I will rewrite complete steps for java.

I am currently using Swagger V2 with Spring Boot 2 and it's straightforward 3 step process.

Step 1: Add required dependencies in pom.xml file. The second dependency is optional use it only if you need Swagger UI.

        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

Step 2: Add configuration class

@Configuration
@EnableSwagger2
public class SwaggerConfig {

     public static final Contact DEFAULT_CONTACT = new Contact("Usama Amjad", "https://stackoverflow.com/users/4704510/usamaamjad", "[email protected]");
      public static final ApiInfo DEFAULT_API_INFO = new ApiInfo("Article API", "Article API documentation sample", "1.0", "urn:tos",
              DEFAULT_CONTACT, "Apache 2.0", "http://www.apache.org/licenses/LICENSE-2.0", new ArrayList<VendorExtension>());

    @Bean
    public Docket api() {
        Set<String> producesAndConsumes = new HashSet<>();
        producesAndConsumes.add("application/json");
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(DEFAULT_API_INFO)
                .produces(producesAndConsumes)
                .consumes(producesAndConsumes);

    }
}

Step 3: Setup complete and now you need to document APIs in controllers

    @ApiOperation(value = "Returns a list Articles for a given Author", response = Article.class, responseContainer = "List")
    @ApiResponses(value = { @ApiResponse(code = 200, message = "Success"),
            @ApiResponse(code = 404, message = "The resource you were trying to reach is not found") })
    @GetMapping(path = "/articles/users/{userId}")
    public List<Article> getArticlesByUser() {
       // Do your code
    }

Usage:

You can access your Documentation from http://localhost:8080/v2/api-docs just copy it and paste in Postman to import collection.

Optional Swagger UI: You can also use standalone UI without any other rest client via http://localhost:8080/swagger-ui.html and it's pretty good, you can host your documentation without any hassle.

use the include is the easiest way as per

http://www.vistax64.com/powershell/168315-get-childitem-filter-files-multiple-extensions.html

For eslint:

"editor.codeActionsOnSave": { "source.fixAll.eslint": true }

Look at the internals of the Date class and you will see that you can extract all the bits (date, month, year, hour, etc).

http://www.w3schools.com/jsref/jsref_obj_date.asp

For something like Fri 23:00 1 Feb 2013 the code is like:

date = new Date();_x000D_
_x000D_
weekdayNames = ['Sun', 'Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat'];_x000D_
monthNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"];_x000D_
var dateString = weekdayNames[date.getDay()] + " " _x000D_
    + date.getHours() + ":" + ("00" + date.getMinutes()).slice(-2) + " " _x000D_
    + date.getDate() + " " + monthNames[date.getMonth()] + " " + date.getFullYear();_x000D_
_x000D_
console.log(dateString);

**** Modified 2019-05-29 to keep 3 downvoters happy

The solutions posted so far are needlessly complicated, in my opinion. There's a simpler way. The documentation of ui-router says listen to $locationChangeSuccess and use $urlRouter.sync() to check a state transition, halt it, or resume it. But even that actually doesn't work.

However, here are two simple alternatives. Pick one:

Solution 1: listening on $locationChangeSuccess

You can listen to $locationChangeSuccess and you can perform some logic, even asynchronous logic there. Based on that logic, you can let the function return undefined, which will cause the state transition to continue as normal, or you can do $state.go('logInPage'), if the user needs to be authenticated. Here's an example:

angular.module('App', ['ui.router'])

// In the run phase of your Angular application  
.run(function($rootScope, user, $state) {

  // Listen to '$locationChangeSuccess', not '$stateChangeStart'
  $rootScope.$on('$locationChangeSuccess', function() {
    user
      .logIn()
      .catch(function() {
        // log-in promise failed. Redirect to log-in page.
        $state.go('logInPage')
      })
  })
})

Keep in mind that this doesn't actually prevent the target state from loading, but it does redirect to the log-in page if the user is unauthorized. That's okay since real protection is on the server, anyway.

Solution 2: using state resolve

In this solution, you use ui-router resolve feature.

You basically reject the promise in resolve if the user is not authenticated and then redirect them to the log-in page.

Here's how it goes:

angular.module('App', ['ui.router'])

.config(
  function($stateProvider) {
    $stateProvider
      .state('logInPage', {
        url: '/logInPage',
        templateUrl: 'sections/logInPage.html',
        controller: 'logInPageCtrl',
      })
      .state('myProtectedContent', {
        url: '/myProtectedContent',
        templateUrl: 'sections/myProtectedContent.html',
        controller: 'myProtectedContentCtrl',
        resolve: { authenticate: authenticate }
      })
      .state('alsoProtectedContent', {
        url: '/alsoProtectedContent',
        templateUrl: 'sections/alsoProtectedContent.html',
        controller: 'alsoProtectedContentCtrl',
        resolve: { authenticate: authenticate }
      })

    function authenticate($q, user, $state, $timeout) {
      if (user.isAuthenticated()) {
        // Resolve the promise successfully
        return $q.when()
      } else {
        // The next bit of code is asynchronously tricky.

        $timeout(function() {
          // This code runs after the authentication promise has been rejected.
          // Go to the log-in page
          $state.go('logInPage')
        })

        // Reject the authentication promise to prevent the state from loading
        return $q.reject()
      }
    }
  }
)

Unlike the first solution, this solution actually prevents the target state from loading.

I had the same problem, because as soon as display: x; is in animation, it won't animate.

I ended up in creating custom keyframes, first changing the display value then the other values. May give a better solution.

Or, instead of using display: none; use position: absolute; visibility: hidden; It should work.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

You can do it simply with ECMAScript 6,

var array1 = ["Vijendra", "Singh"];
var array2 = ["Singh", "Shakya"];
var array3 = [...new Set([...array1 ,...array2])];
console.log(array3); // ["Vijendra", "Singh", "Shakya"];

• Use the spread operator for concatenating the array.
• Use Set for creating a distinct set of elements.
• Again use the spread operator to convert the Set into an array.

Regarding python2 (and python2 only), some of the former answers rely on using the following hack:

import sys
reload(sys)  # Reload is a hack
sys.setdefaultencoding('UTF8')

It is discouraged to use it (check this or this)

In my case, it come with a side-effect: I'm using ipython notebooks, and once I run the code the ´print´ function no longer works. I guess there would be solution to it, but still I think using the hack should not be the correct option.

After trying many options, the one that worked for me was using the same code in the sitecustomize.py, where that piece of code is meant to be. After evaluating that module, the setdefaultencoding function is removed from sys.

So the solution is to append to file /usr/lib/python2.7/sitecustomize.py the code:

import sys
sys.setdefaultencoding('UTF8')

When I use virtualenvwrapper the file I edit is ~/.virtualenvs/venv-name/lib/python2.7/sitecustomize.py.

And when I use with python notebooks and conda, it is ~/anaconda2/lib/python2.7/sitecustomize.py

If you're using SQL (which you didn't say):

select cast(column as varchar(200)) from table 

You can use it in any statement, for example:

select value where othervalue in( select cast(column as varchar(200)) from table)
from othertable

If you want to do a join query, the answer is here already in another post :)

On Windows, a good 3-way diff/merge tool remains kdiff3 (WinMerge, for now, is still 2-way based, pending WinMerge3)

See "How do you merge in GIT on Windows?" and this config.

Update 7 years later (Aug. 2018): Artur Kedzior mentions in the comments:

If you guys happen to use Visual Studio (Community Edition is free), try the tool that is shipped with it: vsDiffMerge.exe. It's really awesome and easy to use.

$('div').attr('class').split(' ').each(function(cls){ console.log(cls);})

How about persisting the object as a blob

skaffman seems to be giving a good answer.

another way is probably to format the XML using a commmand line utility like xmlstarlet(http://xmlstar.sourceforge.net/) and then format both the strings and then use any diff utility(library) to diff the resulting output files. I don't know if this is a good solution when issues are with namespaces.

This is my implementation:

public class CardsDeck {
    private ArrayList<Card> mCards;
    private ArrayList<Card> mPulledCards;
    private Random mRandom;

Look closely at the two dashes in

unzipRelease –Src '$ReleaseFile' -Dst '$Destination'

This first one is not a normal dash but an en-dash (– in HTML). Replace that with the dash found before Dst.

I've discovered that you can make logs with colors using ANSI color codes, what makes easier to find specific messages in debug. Try it:

console.log( "\u001b[1;31m Red message" );
console.log( "\u001b[1;32m Green message" );
console.log( "\u001b[1;33m Yellow message" );
console.log( "\u001b[1;34m Blue message" );
console.log( "\u001b[1;35m Purple message" );
console.log( "\u001b[1;36m Cyan message" );

As AnaPana mentioned pathlib is more new and easier in python 3.4 and there is new with_suffix method that can handle this problem easily:

from pathlib import Path
new_filename = Path(mysequence.fasta).with_suffix('.aln')

For one-way data binding from parent to child, use the @Input decorator (as recommended by the style guide) to specify an input property on the child component

@Input() model: any;   // instead of any, specify your type

and use template property binding in the parent template

<child [model]="parentModel"></child>

Since you are passing an object (a JavaScript reference type) any changes you make to object properties in the parent or the child component will be reflected in the other component, since both components have a reference to the same object. I show this in the Plunker.

If you reassign the object in the parent component

this.model = someNewModel;

Angular will propagate the new object reference to the child component (automatically, as part of change detection).

The only thing you shouldn't do is reassign the object in the child component. If you do this, the parent will still reference the original object. (If you do need two-way data binding, see https://stackoverflow.com/a/34616530/215945).

@Component({
  selector: 'child',
  template: `<h3>child</h3> 
    <div>{{model.prop1}}</div>
    <button (click)="updateModel()">update model</button>`
})
class Child {
  @Input() model: any;   // instead of any, specify your type
  updateModel() {
    this.model.prop1 += ' child';
  }
}

@Component({
  selector: 'my-app',
  directives: [Child],
  template: `
    <h3>Parent</h3>
    <div>{{parentModel.prop1}}</div>
    <button (click)="updateModel()">update model</button>
    <child [model]="parentModel"></child>`
})
export class AppComponent {
  parentModel = { prop1: '1st prop', prop2: '2nd prop' };
  constructor() {}
  updateModel() { this.parentModel.prop1 += ' parent'; }
}

You are running the Command Prompt as an admin. You have only defined PYTHON for your user. You need to define it in the bottom "System variables" section.

Also, you should only point the variable to the folder, not directly to the executable.

Put this right before the closing Body tag at the bottom of the page.

<script>
    if (location.hash) {
        location.href = location.hash;
    }
</script>

jQuery is actually not required.

Any user with a valid shell in /etc/passwd can potentially login. If you want to improve security, set up SSH with public-key authentication (there is lots of info on the web on doing this), install a public key in one user's ~/.ssh/authorized_keys file, and disable password-based authentication. This will prevent anybody except that one user from logging in, and will require that the user have in their possession the matching private key. Make sure the private key has a decent passphrase.

To prevent bots from trying to get in, run SSH on a port other than 22 (i.e. 3456). This doesn't improve security but prevents script-kiddies and bots from cluttering up your logs with failed attempts.

You might also be able to use pstree:

pstree -p user

This typically gives a text representation of all the processes for the "user" and the -p option gives the process-id. It does not depend, as far as I understand, on having the processes be owned by the current shell. It also shows forks.

This is my c++11 style solution. parameter 'base' is for base class of all sub-classes. creators, are std::function objects to create sub-class instances, might be a binding to your sub-class' static member function 'create(some args)'. This maybe not perfect but works for me. And it is kinda 'general' solution.

template <class base, class... params> class factory {
public:
  factory() {}
  factory(const factory &) = delete;
  factory &operator=(const factory &) = delete;

  auto create(const std::string name, params... args) {
    auto key = your_hash_func(name.c_str(), name.size());
    return std::move(create(key, args...));
  }

  auto create(key_t key, params... args) {
    std::unique_ptr<base> obj{creators_[key](args...)};
    return obj;
  }

  void register_creator(const std::string name,
                        std::function<base *(params...)> &&creator) {
    auto key = your_hash_func(name.c_str(), name.size());
    creators_[key] = std::move(creator);
  }

protected:
  std::unordered_map<key_t, std::function<base *(params...)>> creators_;
};

An example on usage.

class base {
public:
  base(int val) : val_(val) {}

  virtual ~base() { std::cout << "base destroyed\n"; }

protected:
  int val_ = 0;
};

class foo : public base {
public:
  foo(int val) : base(val) { std::cout << "foo " << val << " \n"; }

  static foo *create(int val) { return new foo(val); }

  virtual ~foo() { std::cout << "foo destroyed\n"; }
};

class bar : public base {
public:
  bar(int val) : base(val) { std::cout << "bar " << val << "\n"; }

  static bar *create(int val) { return new bar(val); }

  virtual ~bar() { std::cout << "bar destroyed\n"; }
};

int main() {
  common::factory<base, int> factory;

  auto foo_creator = std::bind(&foo::create, std::placeholders::_1);
  auto bar_creator = std::bind(&bar::create, std::placeholders::_1);

  factory.register_creator("foo", foo_creator);
  factory.register_creator("bar", bar_creator);

  {
    auto foo_obj = std::move(factory.create("foo", 80));
    foo_obj.reset();
  }

  {
    auto bar_obj = std::move(factory.create("bar", 90));
    bar_obj.reset();
  }
}

What you're trying to insert is not a date, I think, but a string. You need to use to_date() function, like this:

insert into table t1 (id, date_field) values (1, to_date('20.06.2013', 'dd.mm.yyyy'));

You can also try

System.Environment.GetEnvironmentVariable("UserName");

1. Uninstall all JDKs installed on your computer from the Java Control Panel
2. Search for C:\ProgramData\Oracle\Java and delete that directory and all files contained within. You can do this from the command line using rmdir /S C:\ProgramData\Oracle\Java
3. Then search for C:\ProgramData\Oracle and delete the oracle folder. You can do this using rmdir /S C:\ProgramData\Oracle

4. Now install JDK and set the path.

5. Run the program.You won't find the same problem anymore.

I use the below query for tracing application activity on a SQL server that does not have trace profiler enabled. The method uses Query Store (SQL Server 2016+) instead of the DMV's. This gives better ability to look into historical data, as well as faster lookups. It is very efficient to capture short-running queries that can't be captured by sp_who/sp_whoisactive.

    Run full script (F5) -> Interact with UI -> Run full script again (F5)

Well, Reflector itself is a .NET assembly so you can open Reflector.exe in Reflector to check out how it's built.

No need for Gson or JSON parsing libraries. Just using new JSONObject(Map<String, JSONObject>).toString(), e.g:

/**
 * convert target map to JSON string
 *
 * @param map the target map
 * @return JSON string of the map
 */
@NonNull public String toJson(@NonNull Map<String, Target> map) {
    final Map<String, JSONObject> flatMap = new HashMap<>();
    for (String key : map.keySet()) {
        try {
            flatMap.put(key, toJsonObject(map.get(key)));
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
    try {
        // 2 indentSpaces for pretty printing
        return new JSONObject(flatMap).toString(2);
    } catch (JSONException e) {
        e.printStackTrace();
        return "{}";
    }
}

You can only call notify on objects where you own their monitor. So you need something like

synchronized(threadObject)
{
   threadObject.notify();
}

sys.tables

Contains all tables. so exec this query to get all tables with details.

SELECT * FROM sys.tables

or simply select Name from sys.tables to get the name of all tables.

SELECT Name From sys.tables

In Python, curly braces are used to define a dictionary.

a={'one':1, 'two':2, 'three':3}
a['one']=1
a['three']=3

In other languages, { } are used as part of the flow control. Python however used indentation as its flow control because of its focus on readable code.

for entry in entries:
     code....

There's a little easter egg in Python when it comes to braces. Try running this on the Python Shell and enjoy.

Use this Layout in your xml file

<LinearLayout
  android:id="@+id/contacts_type"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:visibility="gone">
</LinearLayout>

Define your layout in .class file

 LinearLayout linearLayout = (LinearLayout) findViewById(R.id.contacts_type);

Now if you want to display this layout just write

 linearLayout.setVisibility(View.VISIBLE);

and if you want to hide layout just write

 linearLayout.setVisibility(View.INVISIBLE);

updated() should be what you're looking for:

Called after a data change causes the virtual DOM to be re-rendered and patched.

The component’s DOM will have been updated when this hook is called, so you can perform DOM-dependent operations here.

First of all you need to include in your project

using System.Diagnostics;

After that you could write a general method that you could use for different .exe files that you want to use. It would be like below:

public void ExecuteAsAdmin(string fileName)
{
    Process proc = new Process();
    proc.StartInfo.FileName = fileName;
    proc.StartInfo.UseShellExecute = true;
    proc.StartInfo.Verb = "runas";
    proc.Start();
}

If you want to for example execute notepad.exe then all you do is you call this method:

ExecuteAsAdmin("notepad.exe");

UPDATE: The really awesome code posted by Gabe Sechan no longer works unless you explicitly request the user to grant the necessary permissions. Here is some code that you can place in your main activity to request these permissions:

    if (getApplicationContext().checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.READ_PHONE_STATE},
                MY_PERMISSIONS_REQUEST_READ_PHONE_STATE);
    }

    if (getApplicationContext().checkSelfPermission(Manifest.permission.PROCESS_OUTGOING_CALLS)
            != PackageManager.PERMISSION_GRANTED) {
        // Permission has not been granted, therefore prompt the user to grant permission
        ActivityCompat.requestPermissions(this,
                new String[]{Manifest.permission.PROCESS_OUTGOING_CALLS},
                MY_PERMISSIONS_REQUEST_PROCESS_OUTGOING_CALLS);
    }

ALSO: As someone mentioned in a comment below Gabe's post, you have to add a little snippet of code, android:enabled="true, to the receiver in order to detect incoming calls when the app is not currently running in the foreground:

    <!--This part is inside the application-->
    <receiver android:name=".CallReceiver" android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.PHONE_STATE" />
        </intent-filter>
        <intent-filter>
            <action android:name="android.intent.action.NEW_OUTGOING_CALL" />
        </intent-filter>
    </receiver>

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

To expand on the Wikipedia-based answers:

The Social Security Administration (SSA) explicitly states in this document that the having "000" in the first group of numbers "will NEVER be a valid SSN":

• http://www.socialsecurity.gov/employer/stateweb.htm

I'd consider that pretty definitive.

However, that the 2nd or 3rd groups of numbers won't be "00" or "0000" can be inferred from a FAQ that the SSA publishes which indicates that allocation of those groups starts at "01" or "0001":

• http://ssa-custhelp.ssa.gov/cgi-bin/ssa.cfg/php/enduser/std_adp.php?p_faqid=87

But this is only a FAQ and it's never outright stated that "00" or "0000" will never be used.

In another FAQ they provide (http://www.socialsecurity.gov/employer/randomizationfaqs.html#a0=6) that "00" or "0000" will never be used.

I can't find a reference to the 'advertisement' reserved SSNs on the SSA site, but it appears that no numbers starting with a 3 digit number higher than 772 (according to the document referenced above) have been assigned yet, but there's nothing I could find that states those numbers are reserved. Wikipedia's reference is a book that I don't have access to. The Wikipedia information on the advertisement reserved numbers is mentioned across the web, but many are clearly copied from Wikipedia. I think it would be nice to have a citation from the SSA, though I suspect that now that Wikipedia has made the idea popular that these number would now have to be reserved for advertisements even if they weren't initially.

The SSA has a page with a couple of stories about SSN's they've had to retire because they were used in advertisements/samples (maybe the SSA should post a link to whatever their current policy on this might be):

• http://www.ssa.gov/history/ssn/misused.html

Since seaborn also uses matplotlib to do its plotting you can easily combine the two. If you only want to adopt the styling of seaborn the set_style function should get you started:

import matplotlib.pyplot as plt
import numpy as np
import seaborn as sns

sns.set_style("darkgrid")
plt.plot(np.cumsum(np.random.randn(1000,1)))
plt.show()

Result:

One of the most well known solutions is a variation of your solution number 3 that uses a pseudo element instead of a non-semantic html element.

It goes something like this...

.cf:after {
    content: " ";
    display: block;
    visibility: hidden;
    height: 0;
    clear: both;
}

You place that in your stylesheet, and all you need is to add the class 'cf' to the element containing the floats.

What I use is another variation which comes from Nicolas Gallagher.

It does the same thing, but it's shorter, looks neater, and maybe used to accomplish another thing that's pretty useful - preventing the child elements' margins from collapsing with it's parents' (but for that you do need something else - read more about it here http://nicolasgallagher.com/micro-clearfix-hack/ ).

.cf:after {
    content: " ";
    display: table;
    clear: float;
}

If you are targeting iOS 5+ (what covers the whole iOS world), best use NSOrderedSet. It removes duplicates and retains the order of your NSArray.

Just do

NSOrderedSet *orderedSet = [NSOrderedSet orderedSetWithArray:yourArray];

You can now convert it back to a unique NSArray

NSArray *uniqueArray = orderedSet.array;

Or just use the orderedSet because it has the same methods like an NSArray like objectAtIndex:, firstObject and so on.

A membership check with contains is even faster on the NSOrderedSet than it would be on an NSArray

For more checkout the NSOrderedSet Reference

Put config.assets.debug = false in config/environments/development.rb.

The Data Access Object is basically an object or an interface that provides access to an underlying database or any other persistence storage.

That definition from: http://en.wikipedia.org/wiki/Data_access_object

Check also the sequence diagram here: http://www.oracle.com/technetwork/java/dataaccessobject-138824.html

Maybe a simple example can help you understand the concept:

Let's say we have an entity to represent an employee:

public class Employee {

    private int id;
    private String name;


    public int getId() {
        return id;
    }
    public void setId(int id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }

}

The employee entities will be persisted into a corresponding Employee table in a database. A simple DAO interface to handle the database operation required to manipulate an employee entity will be like:

interface EmployeeDAO {

    List<Employee> findAll();
    List<Employee> findById();
    List<Employee> findByName();
    boolean insertEmployee(Employee employee);
    boolean updateEmployee(Employee employee);
    boolean deleteEmployee(Employee employee);

}

Next we have to provide a concrete implementation for that interface to deal with SQL server, and another to deal with flat files, etc.

The following aggregation operation randomly selects 3 documents from the collection:

db.users.aggregate( [ { $sample: { size: 3 } } ] )

Use @Html.Raw() with caution as you may cause more trouble with encoding and security. I understand the use case as I had to do this myself, but carefully... Just avoid allowing all text through. For example only preserve/convert specific character sequences and always encode the rest:

@Html.Raw(Html.Encode(myString).Replace("\n", "<br/>"))

Then you have peace of mind that you haven't created a potential security hole and any special/foreign characters are displayed correctly in all browsers.

$destroy can refer to 2 things: method and event

1. method - $scope.$destroy

.directive("colorTag", function(){
  return {
    restrict: "A",
    scope: {
      value: "=colorTag"
    },
    link: function (scope, element, attrs) {
      var colors = new App.Colors();
      element.css("background-color", stringToColor(scope.value));
      element.css("color", contrastColor(scope.value));

      // Destroy scope, because it's no longer needed.
      scope.$destroy();
    }
  };
})

2. event - $scope.$on("$destroy")

See @SunnyShah's answer.

This is works for me:

myEditText.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(myEditText.isFocused()){
                myEditText.requestFocus();
                myEditText.clearFocus();
                myEditText.setSelection(myEditText.getText().length(), 0);
            }else{
                myEditText.requestFocus();
                myEditText.clearFocus();
            }

        }
    });

To prevent deadlocks I always try to use Task.Run() when I have to call an async method synchronously that @Heinzi mentions.

However the method has to be modified if the async method uses parameters. For example Task.Run(GenerateCodeAsync("test")).Result gives the error:

Argument 1: cannot convert from 'System.Threading.Tasks.Task<string>' to 'System.Action'

This could be called like this instead:

string code = Task.Run(() => GenerateCodeAsync("test")).Result;

The list may contain several elements, so the get method takes an argument : the index of the element you want to retrieve. If you want the first one, then it's 0.

The list contains Car instances, so you just have to do

Car firstCar = car.get(0);
String price = firstCar.getPrice();

or just

String price = car.get(0).getPrice();

The car variable should be named cars, since it's a list and thus contains several cars.

Read the tutorial about collections. And learn to use the javadoc: all the classes and methods are documented.

A normal variable is set by simply assigning it a value; note that no whitespace is allowed around the =:

HOME=c

An environment variable is a regular variable that has been marked for export to the environment.

export HOME
HOME=c

You can combine the assignment with the export statement.

export HOME=c

I'm guessing you're running python3, in which input(prompt) returns a string. Try this.

By default mesh will color surface values based on the (default) jet colormap (i.e. hot is higher). You can additionally use surf for filled surface patches and set the 'EdgeColor' property to 'None' (so the patch edges are non-visible).

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;

% surface in 3D
figure;
surf(Z,'EdgeColor','None');

2D map: You can get a 2D map by switching the view property of the figure

% 2D map using view
figure;
surf(Z,'EdgeColor','None');
view(2);    

... or treating the values in Z as a matrix, viewing it as a scaled image using imagesc and selecting an appropriate colormap.

% using imagesc to view just Z
figure;
imagesc(Z); 
colormap jet; 

The color pallet of the map is controlled by colormap(map), where map can be custom or any of the built-in colormaps provided by MATLAB:

Update/Refining the map: Several design options on the map (resolution, smoothing, axis etc.) can be controlled by the regular MATLAB options. As @Floris points out, here is a smoothed, equal-axis, no-axis labels maps, adapted to this example:

figure;
surf(X, Y, Z,'EdgeColor', 'None', 'facecolor', 'interp');
view(2);
axis equal; 
axis off;

According to the Twitter Bootstrap documentation: http://getbootstrap.com/css/#helper-classes-center

<!-- Button -->
<div class="form-group">
   <label class="col-md-4 control-label" for="singlebutton"></label>
   <div class="col-md-4 center-block">
      <button id="singlebutton" name="singlebutton" class="btn btn-primary center-block">
          Next Step!
       </button>
   </div>  
</div>

All the class center-block does is to tell the element to have a margin of 0 auto, the auto being the left/right margins. However, unless the class text-center or css text-align:center; is set on the parent, the element does not know the point to work out this auto calculation from so will not center itself as anticipated.

See an example of the code above here: https://jsfiddle.net/Seany84/2j9pxt1z/

ShortcutBadger is a library that adds an abstraction layer over the device brand and current launcher and offers a great result. Works with LG, Sony, Samsung, HTC and other custom Launchers.

It even has a way to display Badge Count in Pure Android devices desktop.

Updating the Badge Count in the application icon is as easy as calling:

int badgeCount = 1;
ShortcutBadger.applyCount(context, badgeCount);

It includes a demo application that allows you to test its behavior.

keytool is a tool to manage (public/private) security keys and certificates and store them in a Java KeyStore file (stored_file_name.jks).
It is provided with any standard JDK/JRE distributions.

static_cast< Type* >(ptr)

static_cast in C++ can be used in scenarios where all type casting can be verified at compile time.

dynamic_cast< Type* >(ptr)

dynamic_cast in C++ can be used to perform type safe down casting. dynamic_cast is run time polymorphism. The dynamic_cast operator, which safely converts from a pointer (or reference) to a base type to a pointer (or reference) to a derived type.

eg 1:

#include <iostream>
using namespace std;

class A
{
public:
    virtual void f(){cout << "A::f()" << endl;}
};

class B : public A
{
public:
    void f(){cout << "B::f()" << endl;}
};

int main()
{
    A a;
    B b;
    a.f();        // A::f()
    b.f();        // B::f()

    A *pA = &a;   
    B *pB = &b;   
    pA->f();      // A::f()
    pB->f();      // B::f()

    pA = &b;
    // pB = &a;      // not allowed
    pB = dynamic_cast<B*>(&a); // allowed but it returns NULL

    return 0;
}

eg 2:

#include <iostream>

using namespace std;

class A {
public:
    virtual void print()const {cout << " A\n";}
};

class B {
public:
    virtual void print()const {cout << " B\n";}
};

class C: public A, public B {
public:
    void print()const {cout << " C\n";}
};


int main()
{

    A* a = new A;
    B* b = new B;
    C* c = new C;

    a -> print(); b -> print(); c -> print();
    b = dynamic_cast< B*>(a);  //fails
    if (b)  
       b -> print();  
    else 
       cout << "no B\n";
    a = c;
    a -> print(); //C prints
    b = dynamic_cast< B*>(a);  //succeeds
    if (b)
       b -> print();  
    else 
       cout << "no B\n";
}

I solved my problem using:

top -n1 -b | grep "proccess name"

in this case: -n is used to set how many times top will what proccess
and -b is used to show all pids

it's prevents errors like : top: pid limit (20) exceeded

See the "Threading" section of this page: http://msdn.microsoft.com/en-us/library/ff647786.aspx, in conjunction with the "Connections" section.

Have you tried upping the maxconnection attribute of your processModel setting?

Dot notation and the properties are equivalent. So you would accomplish like so:

var myObj = new Object;
var a = 'string1';
myObj[a] = 'whatever';
alert(myObj.string1)

(alerts "whatever")

No need for a separate SELECT...

INSERT INTO table (name)
OUTPUT Inserted.ID
VALUES('bob');

This works for non-IDENTITY columns (such as GUIDs) too

This doesn't quite yet look like what I want, but I accomplished something like this by stacking nav pills in the leftmost two spans. This is what my app's app/views/layouts/application.html.erb file looks like:

<!DOCTYPE html>
...
  <body>
    <!-- top navigation bar -->
    <div class="navbar navbar-fixed-top">
       ...
    </div>
    <div class="container-fluid">
      <!-- the navigation buttons bar on the left -->
      <div class="sidebar-nav span2"> <!-- we reserve 2 spans out of 12 for this -->
        <ul class="nav nav-pills nav-stacked">
          <li class="<%= current_page?(root_path) ? 'active' : 'inactive' %>">
            <%= link_to "Home", root_path %>
          </li>
          <li class="<%= current_page?(section_a_path) ? 'active' : 'inactive' %>">
            <%= link_to "Section A", section_a_path %>
          </li>
          <li class="<%= current_page?(section_b_path) ? 'active' : 'inactive' %>">
            <%= link_to "Section B", section_b_path %>
          </li>
        </ul>
      </div>
      <div class="container-fluid span10"> <!-- use the remaining 10 spans -->
        <%= flash_messages %>
        <%= yield :layout %> <!-- the content page sees a full 12 spans -->
      </div>
    </div> <!-- class="container-fluid" -->
    ...
  </body>
</html>

Now the stacked pills appear on the top left, below the navbar. When the user clicks on one of them, the corresponding page loads. From the point of view of application.html.erb, that page has the 10 rightmost spans available for it, but from the page's view, it has the full 12 spans available.

The button corresponding to the page currently being displayed is rendered as active, and the others as inactive. Specify the colours for active and inactive buttons in file app/assets/stylesheets/custom.css.scss (in this case, the colour for a disabled state is also defined):

@import "bootstrap";
...
$spray:       #81c9e2;
$grey_light:  #dddddd;
...
.nav-pills {
    .inactive > a, .inactive > a:hover {
        background-color: $spray;
    }
    .disabled > a, .disabled > a:hover {
        background-color: $grey_light;
    }
}

The active pill's colour is not defined, so it appears as the default blue.

File custom.css.scss is included because of the line *= require_tree . in file app/assets/stylesheets/application.css.

For Kotlin

What will you get:

Gray color if the hint is selected

Drop down list with gray color of the hint

Black color if something else than the hint is selected

I have added 5. step what changes the color of the text in the spinner depending on the selected item, because I couldn't find it here. In this case it is needed to change the text color to gray when the first item is selected in order to it looks like a hint.

1. Define a spinner in your activity_layout.xml

   <Spinner
       android:id="@+id/mySpinner"
       android:layout_width="match_parent"
       android:layout_height="wrap_content" />
   

2. Define the string array in string.xml where the first item will be a hint.

   <string-array name="your_string_array">
       <item>Hint...</item>
       <item>Item1</item>
       <item>Item2</item>
       <item>Item3</item>
   </string-array>
   

3. Set up the spinner in the onCreate method in your Activity.kt

   Get string array from resources

       val items= resources.getStringArray(R.array.your_string_array)
   

   Create spinner adapter

       val spinnerAdapter= object : ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, items) {
   
       override fun isEnabled(position: Int): Boolean {
           // Disable the first item from Spinner
           // First item will be use for hint
           return position != 0
       }
   
       override fun getDropDownView(
           position: Int,
           convertView: View?,
           parent: ViewGroup
       ): View {
           val view: TextView = super.getDropDownView(position, convertView, parent) as TextView
           //set the color of first item in the drop down list to gray
           if(position == 0) {
               view.setTextColor(Color.GRAY)
           } else {
               //here is it possible to define color for other items by
               //view.setTextColor(Color.RED)
           }
           return view
       }
   
   }
   

4. Set drop down view resource and attach the adapter to your spinner.

   spinnerAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)     
   mySpinner.adapter = spinnerAdapter
   

5. Change the color of the text in the spinner depending on the selected item

   mySpinner.onItemSelectedListener = object: AdapterView.OnItemSelectedListener{
       override fun onNothingSelected(parent: AdapterView<*>?) {
       }
   
       override fun onItemSelected(
           parent: AdapterView<*>?,
           view: View?,
           position: Int,
           id: Long
       ) {
           val value = parent!!.getItemAtPosition(position).toString()
           if(value == items[0]){
               (view as TextView).setTextColor(Color.GRAY)
           }
       }
   
   }
   

For CentOS, do:

sudo yum install php-mysqli

Another example:

new Promise(function(ok) {
   ok( 
      /* myFunc1(param1, param2, ..) */
   )
}).then(function(){
     /* myFunc1 succeed */
     /* Launch something else */
     /* console.log(whateverparam1) */
     /* myFunc2(whateverparam1, otherparam, ..) */
}).then(function(){
     /* myFunc2 succeed */
     /* Launch something else */
     /* myFunc3(whatever38, ..) */
})

The same logic using arrow functions shorthand.

?? This can cause issues with multiple calls see comments!

The syntax of the first snippet using plain function is preferable here.

new Promise((ok) =>
   ok( 
      /* myFunc1(param1, param2, ..) */
)).then(() =>
     /* myFunc1 succeed */
     /* Launch something else */
     /* Only ONE call or statment can be made inside arrow functions */
     /* For example, using console.log here will break everything */
     /* myFunc2(whateverparam1, otherparam, ..) */
).then(() =>
     /* myFunc2 succeed */
     /* Launch something else */
     /* Only ONE call or statment can be made inside arrow functions */
     /* For example, using console.log here will break everything */
     /* myFunc3(whatever38, ..) */
)

In addition to all the great information on optimising your application on the server side I'd say you should take a look at YSlow. It's a superb resource for improving site performance on the client side.

This applies to all sites, not just ASP.NET MVC.

Use the attribute "title" in every input tag and write a message on it
