Also if you can set JVM timezone this way

System.setProperty("user.timezone", "EST");

or -Duser.timezone=GMT in the JVM args.

In my case I could get the query working by changing "TZR" with "TZD"..

String query = "select * from table1 to_timestamp_tz(origintime,'dd-mm-yyyy hh24:mi:ss TZD') between ?  and ?";

JDBC uses a so-called "connection URL", so you can escape "+" by "%2B", that is

useTimezone=true&serverTimezone=GMT%2B8

Calendar aGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT")); Then all operations performed using the aGMTCalendar object will be done with the GMT time zone and will not have the daylight savings time or fixed offsets applied

Wrong!

Calendar aGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
aGMTCalendar.getTime(); //or getTimeInMillis()

and

Calendar aNotGMTCalendar = Calendar.getInstance(TimeZone.getTimeZone("GMT-2"));aNotGMTCalendar.getTime();

will return the same time. Idem for

new Date(); //it's not GMT.

The accepted solution does not work when there are multiple different timezones in a Series. It throws ValueError: Tz-aware datetime.datetime cannot be converted to datetime64 unless utc=True

The solution is to use the apply method.

Please see the examples below:

# Let's have a series `a` with different multiple timezones. 
> a
0    2019-10-04 16:30:00+02:00
1    2019-10-07 16:00:00-04:00
2    2019-09-24 08:30:00-07:00
Name: localized, dtype: object

> a.iloc[0]
Timestamp('2019-10-04 16:30:00+0200', tz='Europe/Amsterdam')

# trying the accepted solution
> a.dt.tz_localize(None)
ValueError: Tz-aware datetime.datetime cannot be converted to datetime64 unless utc=True

# Make it tz-naive. This is the solution:

# a.tz_convert() also does not work with multiple timezones, but this works:

Since java 8 just use ZonedDateTime.parse("2010-04-05T17:16:00Z")

Here’s the modern answer (valid from 2014 and on). The accepted answer was a very fine answer in 2011. These days I recommend no one uses the Date, DateFormat and SimpleDateFormat classes. It all goes more natural with the modern Java date and time API.

To get a date-time object from your millis:

    ZonedDateTime dateTime = Instant.ofEpochMilli(millis)
            .atZone(ZoneId.of("Australia/Sydney"));

If millis equals 1318388699000L, this gives you 2011-10-12T14:04:59+11:00[Australia/Sydney]. Should the code in some strange way end up on a JVM that doesn’t know Australia/Sydney time zone, you can be sure to be notified through an exception.

If you want the date-time in your string format for presentation:

String formatted = dateTime.format(DateTimeFormatter.ofPattern("dd/MM/yyyy HH:mm:ss"));

Result:

12/10/2011 14:04:59

PS I don’t know what you mean by “The above doesn't work.” On my computer your code in the question too prints 12/10/2011 14:04:59.

import datetime
import pytz

def convert_datetime_timezone(dt, tz1, tz2):

    dt = tz1.localize(dt)
    dt = dt.astimezone(tz2)
    dt = dt.strftime("%Y-%m-%d %H:%M:%S")

    return dt

From the API (http://msdn.microsoft.com/en-us/library/system.datetime_members(VS.71).aspx) it does not seem it can show the name of the time zone used.

Did you try to set timezone by func: http://pl.php.net/manual/en/function.date-default-timezone-set.php

The correct solution is to add the timezone info e.g., to get the current time as an aware datetime object in Python 3:

from datetime import datetime, timezone

now = datetime.now(timezone.utc)

On older Python versions, you could define the utc tzinfo object yourself (example from datetime docs):

from datetime import tzinfo, timedelta, datetime

ZERO = timedelta(0)

class UTC(tzinfo):
  def utcoffset(self, dt):
    return ZERO
  def tzname(self, dt):
    return "UTC"
  def dst(self, dt):
    return ZERO

utc = UTC()

then:

now = datetime.now(utc)

If you have the SUPER privilege, you can set the global server time zone value at runtime with this statement:

mysql> SET GLOBAL time_zone = timezone;

7 years passed and...
actually there's this new SQL Server 2016 feature that does exactly what you need.
It is called AT TIME ZONE and it converts date to a specified time zone considering DST (daylight saving time) changes.
More info here: https://msdn.microsoft.com/en-us/library/mt612795.aspx

For those unable to configure the mysql environment (e.g. due to lack of SUPER access) to use human-friendly timezone names like "America/Denver" or "GMT" you can also use the function with numeric offsets like this:

CONVERT_TZ(date,'+00:00','-07:00')

Using TimeZones class makes it easy to create timezone specific date.

TimeZoneInfo.ConvertTime(DateTime.Now, TimeZoneInfo.FindSystemTimeZoneById(TimeZones.Paris.Id));

Set the default time zone first and get the date then, the date will be in the time zone you specify :

<?php 
 date_default_timezone_set('America/New_York');
 $date= date('m-d-Y') ;
 ?>

http://php.net/manual/en/function.date-default-timezone-set.php

Check this:

function dateToLocalISO(date) {
    const off    = date.getTimezoneOffset()
    const absoff = Math.abs(off)
    return (new Date(date.getTime() - off*60*1000).toISOString().substr(0,23) +
            (off > 0 ? '-' : '+') + 
            (absoff / 60).toFixed(0).padStart(2,'0') + ':' + 
            (absoff % 60).toString().padStart(2,'0'))
}

// Test it:
d = new Date()

dateToLocalISO(d)
// ==> '2019-06-21T16:07:22.181-03:00'

// Is similar to:

moment = require('moment')
moment(d).format('YYYY-MM-DDTHH:mm:ss.SSSZ') 
// ==> '2019-06-21T16:07:22.181-03:00'

A couple of answers already mention that moment-timezone is the way to go with named timezone. I just want to clarify something about this library that was pretty confusing to me. There is a difference between these two statements:

moment.tz(date, format, timezone)

moment(date, format).tz(timezone)

Assuming that a timezone is not specified in the date passed in:

The first code takes in the date and assumes the timezone is the one passed in. The second one will take date, assume the timezone from the browser and then change the time and timezone according to the timezone passed in.

Example:

moment.tz('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss', 'UTC').format() // "2018-07-17T19:00:00Z"

moment('2018-07-17 19:00:00', 'YYYY-MM-DD HH:mm:ss').tz('UTC').format() // "2018-07-18T00:00:00Z"

My timezone is +5 from utc. So in the first case it does not change and it sets the date and time to have utc timezone.

In the second case, it assumes the date passed in is in -5, then turns it into UTC, and that's why it spits out the date "2018-07-18T00:00:00Z"

NOTE: The format parameter is really important. If omitted moment might fall back to the Date class which can unpredictable behaviors

Assuming the timezone is specified in the date passed in:

In this case they both behave equally

Even though now I understand why it works that way, I thought this was a pretty confusing feature and worth explaining.

You do not need to use moment-timezone for this. The main moment.js library has full functionality for working with UTC and the local time zone.

var testDateUtc = moment.utc("2015-01-30 10:00:00");
var localDate = moment(testDateUtc).local();

From there you can use any of the functions you might expect:

var s = localDate.format("YYYY-MM-DD HH:mm:ss");
var d = localDate.toDate();
// etc...

Note that by passing testDateUtc, which is a moment object, back into the moment() constructor, it creates a clone. Otherwise, when you called .local(), it would also change the testDateUtc value, instead of just the localDate value. Moments are mutable.

Also note that if your original input contains a time zone offset such as +00:00 or Z, then you can just parse it directly with moment. You don't need to use .utc or .local. For example:

var localDate = moment("2015-01-30T10:00:00Z");

I'm not exactly sure what it is that you want. Do you want a TimeStamp? Then you can do something simple like:

TimeStamp ts = TimeStamp.FromTicks(value.ToUniversalTime().Ticks);

Since you named a variable epoch, do you want the Unix time equivalent of your date?

DateTime unixStart = DateTime.SpecifyKind(new DateTime(1970, 1, 1), DateTimeKind.Utc);
long epoch = (long)Math.Floor((value.ToUniversalTime() - unixStart).TotalSeconds);

the first option would allow you to take the value from $_POST['whateveryoucalltheselect'] and add it to UTC. or even store that value and then always call UTC + userTZsetting whenever you need it later. seems easiest to me. the last option would be much more valuable if timezones changed frequently.

As of Node 13, you can now repeatedly set process.env.TZ and it will be reflected in the timezone of new Date objects. I don't know if I'd use this in production code but it would definitely be useful in unit tests.

> process.env.TZ = 'Europe/London';
'Europe/London'
> (new Date().toString())
'Fri Mar 20 2020 09:39:59 GMT+0000 (Greenwich Mean Time)'

> process.env.TZ = 'Europe/Amsterdam';
'Europe/Amsterdam'
> (new Date().toString())
'Fri Mar 20 2020 10:40:07 GMT+0100 (Central European Standard Time)'

for Chinese user, just add two lines below to you config/application.rb :

config.active_record.default_timezone = :local
config.time_zone = 'Beijing'

Usually, I work with DATE columns, not the larger but more precise TIMESTAMP used by some answers.

The following will return the current UTC date as just that -- a DATE.

CAST(sys_extract_utc(SYSTIMESTAMP) AS DATE)

I often store dates like this, usually with the field name ending in _UTC to make it clear for the developer. This allows me to avoid the complexity of time zones until last-minute conversion by the user's client. Oracle can store time zone detail with some data types, but those types require more table space than DATE, and knowledge of the original time zone is not always required.

In java, DateFormatter by default uses DST,To avoid day Light saving (DST) you need to manually do a trick,
first you have to get the DST offset i.e. for how many millisecond DST applied, for ex somewhere DST is also for 45 minutes and for some places it is for 30 min
but in most cases DST is of 1 hour
you have to use Timezone object and check with the date whether it is falling under DST or not and then you have to manually add offset of DST into it. for eg:

 TimeZone tz = TimeZone.getTimeZone("EST");
 boolean isDST = tz.inDaylightTime(yourDateObj);
 if(isDST){
 int sec= tz.getDSTSavings()/1000;// for no. of seconds
 Calendar cal= Calendar.getInstance();
 cal.setTime(yourDateObj);
 cal.add(Calendar.Seconds,sec);
 System.out.println(cal.getTime());// your Date with DST neglected
  }

Following up on sas's answer, PHP 5.4, Symfony 2.8, I had to use

ini_set('date.timezone','<whatever timezone string>');

instead of date_default_timezone_set. I also added a call to ini_set to the top of a custom web/config.php to get that check to succeed.

The differences are covered at the PostgreSQL documentation for date/time types. Yes, the treatment of TIME or TIMESTAMP differs between one WITH TIME ZONE or WITHOUT TIME ZONE. It doesn't affect how the values are stored; it affects how they are interpreted.

The effects of time zones on these data types is covered specifically in the docs. The difference arises from what the system can reasonably know about the value:

• With a time zone as part of the value, the value can be rendered as a local time in the client.

• Without a time zone as part of the value, the obvious default time zone is UTC, so it is rendered for that time zone.

The behaviour differs depending on at least three factors:

• The timezone setting in the client.
• The data type (i.e. WITH TIME ZONE or WITHOUT TIME ZONE) of the value.
• Whether the value is specified with a particular time zone.

Here are examples covering the combinations of those factors:

foo=> SET TIMEZONE TO 'Japan';
SET
foo=> SELECT '2011-01-01 00:00:00'::TIMESTAMP;
      timestamp

I'm new to Python, but found a way to convert

2017-05-27T07:20:18.000-04:00 to

2017-05-27T07:20:18 without downloading new utilities.

from datetime import datetime, timedelta

time_zone1 = int("2017-05-27T07:20:18.000-04:00"[-6:][:3])
>>returns -04

item_date = datetime.strptime("2017-05-27T07:20:18.000-04:00".replace(".000", "")[:-6], "%Y-%m-%dT%H:%M:%S") + timedelta(hours=-time_zone1)

I'm sure there are better ways to do this without slicing up the string so much, but this got the job done.

No. There is no single reliable way and there will never be. Did you really think you could trust the client?

$dw = date( "w", $timestamp);

Where $dw will be 0 (for Sunday) through 6 (for Saturday) as you can see here: http://www.php.net/manual/en/function.date.php

I found on the sqlite documentation (https://www.sqlite.org/lang_datefunc.html) this text:

Compute the date and time given a unix timestamp 1092941466, and compensate for your local timezone.

SELECT datetime(1092941466, 'unixepoch', 'localtime');

That didn't look like it fit my needs, so I tried changing the "datetime" function around a bit, and wound up with this:

select datetime(timestamp, 'localtime')

That seems to work - is that the correct way to convert for your timezone, or is there a better way to do this?

If I understood correct,You need to set time zone first like:

date_default_timezone_set('UTC');

And than you can use date function:

// Prints something like: Monday 8th of August 2005 03:12:46 PM
echo date('l jS \of F Y h:i:s A');

Here's a slightly more concise version of @vbem's solution:

from datetime import datetime as dt

dt.utcnow().astimezone().tzinfo

The only substantive difference is that I replaced datetime.datetime.now(datetime.timezone.utc) with datetime.datetime.utcnow(). For brevity, I also aliased datetime.datetime as dt.

For my purposes, I want the UTC offset in seconds. Here's what that looks like:

dt.utcnow().astimezone().utcoffset().total_seconds()

I suspect this is what most people are looking for:

Microsoft Time Zone Index Values

Hopefully MS keeps it up to date even after XP.

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

On server-side it will be not as accurate as with JavaScript. Meanwhile, sometimes it is required to solve such task. Just to share the possible solution in this case I write this answer.

If you need to determine user's time zone it could be done via Geo-IP services. Some of them providing timezone. For example, this one (http://smart-ip.net/geoip-api) could help:

<?php
$ip     = $_SERVER['REMOTE_ADDR']; // means we got user's IP address 
$json   = file_get_contents( 'http://smart-ip.net/geoip-json/' . $ip); // this one service we gonna use to obtain timezone by IP
// maybe it's good to add some checks (if/else you've got an answer and if json could be decoded, etc.)
$ipData = json_decode( $json, true);

if ($ipData['timezone']) {
    $tz = new DateTimeZone( $ipData['timezone']);
    $now = new DateTime( 'now', $tz); // DateTime object corellated to user's timezone
} else {
   // we can't determine a timezone - do something else...
}

For those struggling with this on .NET, see if using DateTimeOffset and/or TimeZoneInfo are worth your while.

If you want to use IANA/Olson time zones, or find the built in types are insufficient for your needs, check out Noda Time, which offers a much smarter date and time API for .NET.

This would be my solution:

_x000D_
_x000D_
    // For time zone:_x000D_
    const timeZone = /\((.*)\)/.exec(new Date().toString())[1];_x000D_
    _x000D_
    // Offset hours:_x000D_
    const offsetHours = new Date().getTimezoneOffset() / 60;_x000D_
    _x000D_
    console.log(`${timeZone}, ${offsetHours}hrs`);
_x000D_
_x000D_
_x000D_

These are 2 equivalent solutions:

(in the following code, you should substitute 'UTC' for zone and now() for timestamp)

1. timestamp AT TIME ZONE zone - SQL-standard-conforming
2. timezone(zone, timestamp) - arguably more readable

The function timezone(zone, timestamp) is equivalent to the SQL-conforming construct timestamp AT TIME ZONE zone.

Explanation:

• zone can be specified either as a text string (e.g., 'UTC') or as an interval (e.g., INTERVAL '-08:00') - here is a list of all available time zones
• timestamp can be any value of type timestamp
• now() returns a value of type timestamp (just what we need) with your database's default time zone attached (e.g. 2018-11-11T12:07:22.3+05:00).
• timezone('UTC', now()) turns our current time (of type timestamp with time zone) into the timezonless equivalent in UTC.
  E.g., SELECT timestamp with time zone '2020-03-16 15:00:00-05' AT TIME ZONE 'UTC' will return 2020-03-16T20:00:00Z.

Docs: timezone()

On my device TimeZone.getDefault() is always returning UTC time zone.

I need to do this to get user configured time zone :

TimeZone.setDefault(null)
val tz = TimeZone.getDefault()

It will return user selected timezone.

The Z stands for 'Zulu' - your times are in UTC. From Wikipedia:

The UTC time zone is sometimes denoted by the letter Z—a reference to the equivalent nautical time zone (GMT), which has been denoted by a Z since about 1950. The letter also refers to the "zone description" of zero hours, which has been used since 1920 (see time zone history). Since the NATO phonetic alphabet and amateur radio word for Z is "Zulu", UTC is sometimes known as Zulu time. This is especially true in aviation, where Zulu is the universal standard.

You can specify a time zone offset on new Date(), for example:

new Date('Feb 28 2013 19:00:00 EST')

or

new Date('Feb 28 2013 19:00:00 GMT-0500')

Since Date store UTC time ( i.e. getTime returns in UTC ), javascript will them convert the time into UTC, and when you call things like toString javascript will convert the UTC time into browser's local timezone and return the string in local timezone, i.e. If I'm using UTC+8:

> new Date('Feb 28 2013 19:00:00 GMT-0500').toString()
< "Fri Mar 01 2013 08:00:00 GMT+0800 (CST)"

Also you can use normal getHours/Minute/Second method:

> new Date('Feb 28 2013 19:00:00 GMT-0500').getHours()
< 8

( This 8 means after the time is converted into my local time - UTC+8, the hours number is 8. )

Also note, that if you happen to be using Yahoo geocoding service you can have timezone information returned to you by setting the correct flag.

http://developer.yahoo.com/geo/placefinder/guide/requests.html#flags-parameter

If you are using the MySql Workbench you can set this by opening up the administrator view and select the Advanced tab. The top section is "Localization" and the first check box should be "default-time-zone". Check that box and then enter your desired time zone, restart the server and you should be good to go.

There is actually a nice Gem called local_time by basecamp to do all of that on client side only, I believe:

https://github.com/basecamp/local_time

Choose a valid timezone from the tzinfo database. They tend to take the form e.g. Africa/Gaborne and US/Eastern

Find the one which matches the city nearest you, or the one which has your timezone, then set your value of TIME_ZONE to match.

This is a bug in mysql-connector-java from version 5.1.33 to 5.1.37. I've reported it here: http://bugs.mysql.com/bug.php?id=79343

Edited: This has been corrected from mysql-connector-java 5.1.39

It was a typo in TimeUtil class in loadTimeZoneMappings method that raises a NPE locating /com/mysql/jdbc/TimeZoneMapping.properties file. If you look at the code, the file should be located within TimeUtil class loader, not TimeZone:

TimeUtil.class.getResourceAsStream(TIME_ZONE_MAPPINGS_RESOURCE);

The parameter useLegacyDatetimeCode allows to correct the difference between client and server timezones automatically when using dates. So it helps you precissely not having to specify timezones in each part. Althought using serverTimeZone parameter is a workaround, and meanwhile the patch is released, you can try better correcting the code by yourself as I did.

• If it's a standalone application, you can try simply to add a corrected com/mysql/jdbc/TimeUtil class to your code and be careful with jar loading order. This can help: https://owenou.com/2010/07/20/patching-with-class-shadowing-and-maven.html

• If it's a web application, the easier solution is to create your own mysql-connector-java-5.1.37-patched.jar, substituting the .class directly into the original jar.

I couldn't get it to work using Calendar. You have to use DateFormat

//Wednesday, July 20, 2011 3:54:44 PM PDT
DateFormat df = DateFormat.getDateTimeInstance(DateFormat.FULL, DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateTimeString = df.format(new Date());

//Wednesday, July 20, 2011
df = DateFormat.getDateInstance(DateFormat.FULL);
df.setTimeZone(TimeZone.getTimeZone("PST"));
final String dateString = df.format(new Date());

//3:54:44 PM PDT
df = DateFormat.getTimeInstance(DateFormat.FULL);
df.setTimeZone(Timezone.getTimeZone("PST"));
final String timeString = df.format(new Date());

Here is one way to generate it with the stdlib:

import time
from datetime import datetime

FORMAT='%Y-%m-%dT%H:%M:%S%z'
date=datetime.strptime(time.strftime(FORMAT, time.localtime()),FORMAT)

date will store the local date and the offset from UTC, not the date at UTC timezone, so you can use this solution if you need to identify which timezone the date is generated at. In this example and in my local timezone:

date
datetime.datetime(2017, 8, 1, 12, 15, 44, tzinfo=datetime.timezone(datetime.timedelta(0, 7200)))

date.tzname()
'UTC+02:00'

The key is adding the %z directive to the representation FORMAT, to indicate the UTC offset of the generated time struct. Other representation formats can be consulted in the datetime module docs

If you need the date at the UTC timezone, you can replace time.localtime() with time.gmtime()

date=datetime.strptime(time.strftime(FORMAT, time.gmtime()),FORMAT)

date    
datetime.datetime(2017, 8, 1, 10, 23, 51, tzinfo=datetime.timezone.utc)

date.tzname()
'UTC'

Edit

This works only on python3. The z directive is not available on python 2 _strptime.py code

The easiest method I've found is this:

NSDate *someDateInUTC = …;
NSTimeInterval timeZoneSeconds = [[NSTimeZone localTimeZone] secondsFromGMT];
NSDate *dateInLocalTimezone = [someDateInUTC dateByAddingTimeInterval:timeZoneSeconds];

You can also make your own nodeJS endpoint, publish it with something like heroku, and access it

require("http").createServer(function (q,r) {
    r.setHeader("accees-control-allow-origin","*")
    r.end(Date.now())
}).listen(process.env.PORT || 80)

Then just access it on JS

fetch ("http://someGerokuApp")
.then(r=>r.text)
. then (r=>console.log(r))

This will still be relative to whatever computer the node app is hosted on, but perhaps you can get the location somehow and provide different endpoints fit the other timezones based on the current one (for example if the server happens to be in California then for a new York timezone just add 1000*60*60*3 milliseconds to Date.now() to add 3 hours)

For simplicity, if it's possible to get the location from the server and send it as a response header, you can just do the calculations for the different time zones in the client side

In fact using heroku they allow you to specify a region that it should be deployed at https://devcenter.heroku.com/articles/regions#specifying-a-region you can use this as reference..

EDIT just realized the timezone is in the date string itself, can just pay the whole thing as a header to be read by the client

require("http").createServer(function (q,r) {
    var d= new Date()
    r.setHeader("accees-control-allow-origin","*")
    r.setHeader("zman", d.toString())
    r.end(d.getTime())
}).listen(process.env.PORT || 80)

In Python 3.3+:

from datetime import datetime, timezone

def utc_to_local(utc_dt):
    return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)

In Python 2/3:

import calendar
from datetime import datetime, timedelta

def utc_to_local(utc_dt):
    # get integer timestamp to avoid precision lost
    timestamp = calendar.timegm(utc_dt.timetuple())
    local_dt = datetime.fromtimestamp(timestamp)
    assert utc_dt.resolution >= timedelta(microseconds=1)
    return local_dt.replace(microsecond=utc_dt.microsecond)

Using pytz (both Python 2/3):

import pytz

local_tz = pytz.timezone('Europe/Moscow') # use your local timezone name here
# NOTE: pytz.reference.LocalTimezone() would produce wrong result here

## You could use `tzlocal` module to get local timezone on Unix and Win32
# from tzlocal import get_localzone # $ pip install tzlocal

# # get local timezone    
# local_tz = get_localzone()

def utc_to_local(utc_dt):
    local_dt = utc_dt.replace(tzinfo=pytz.utc).astimezone(local_tz)
    return local_tz.normalize(local_dt) # .normalize might be unnecessary

Example

def aslocaltimestr(utc_dt):
    return utc_to_local(utc_dt).strftime('%Y-%m-%d %H:%M:%S.%f %Z%z')

print(aslocaltimestr(datetime(2010,  6, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime(2010, 12, 6, 17, 29, 7, 730000)))
print(aslocaltimestr(datetime.utcnow()))

Output

2010-06-06 21:29:07.730000 MSD+0400
2010-12-06 20:29:07.730000 MSK+0300
2012-11-08 14:19:50.093745 MSK+0400

2010-06-06 21:29:07.730000 
2010-12-06 20:29:07.730000

2012-11-08 14:19:50.146917 MSK+0400

Note: it takes into account DST and the recent change of utc offset for MSK timezone.

I don't know whether non-pytz solutions work on Windows.

As strtotime requires specific input format, DateTime::createFromFormat could be used (php 5.3+ is required)

// set timezone to user timezone
date_default_timezone_set($str_user_timezone);

// create date object using any given format
$date = DateTime::createFromFormat($str_user_dateformat, $str_user_datetime);

// convert given datetime to safe format for strtotime
$str_user_datetime = $date->format('Y-m-d H:i:s');

// convert to UTC
$str_UTC_datetime = gmdate($str_server_dateformat, strtotime($str_user_datetime));

// return timezone to server default
date_default_timezone_set($str_server_timezone);

In the format of unutbu's answer; I made a utility module that handles things like this, with more intuitive syntax. Can be installed with pip.

import datetime
import saturn

unaware = datetime.datetime(2011, 8, 15, 8, 15, 12, 0)
now_aware = saturn.fix_naive(unaware)

now_aware_madrid = saturn.fix_naive(unaware, 'Europe/Madrid')

This code return me GMT offset.

Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"),
                Locale.getDefault());
Date currentLocalTime = calendar.getTime();
DateFormat date = new SimpleDateFormat("Z");
String localTime = date.format(currentLocalTime);

It returns the time zone offset like this: +0530

If we use SimpleDateFormat below

DateFormat date = new SimpleDateFormat("z",Locale.getDefault());
String localTime = date.format(currentLocalTime);

It returns the time zone offset like this: GMT+05:30

ZoneId here = ZoneId.of("Europe/Kiev");
ZonedDateTime hereAndNow = Instant.now().atZone(here);
String.format("%tz", hereAndNow);

will give you a standardized string representation like "+0300"

There is no such thing as an "epoch" in a specific timezone. The epoch is well-defined as a specific moment in time, so if you change the timezone, the time itself changes as well. Specifically, this time is Jan 1 1970 00:00:00 UTC. So time.time() returns the number of seconds since the epoch.

There are several timezones in operation here:

1. Java's Date classes (util and sql), which have implicit timezones of UTC
2. The timezone your JVM is running in, and
3. the default timezone of your database server.

All of these can be different. Hibernate/JPA has a severe design deficiency in that a user cannot easily ensure that timezone information is preserved in the database server (which allows reconstruction of correct times and dates in the JVM).

Without the ability to (easily) store timezone using JPA/Hibernate then information is lost and once information is lost it becomes expensive to construct it (if at all possible).

I would argue that it is better to always store timezone information (should be the default) and users should then have the optional ability to optimize the timezone away (although it only really affects display, there is still an implicit timezone in any date).

Sorry, this post doesn't provide a work-around (that's been answered elsewhere) but it is a rationalization of why always storing timezone information around is important. Unfortunately it seems many Computer Scientists and programming practitioners argue against the need for timezones simply because they don't appreciate the "loss of information" perspective and how that makes things like internationalization very difficult - which is very important these days with web sites accessible by clients and people in your organization as they move around the world.

You can try this as well, it is easy to implement

TimeZone time2 = TimeZone.CurrentTimeZone;
DateTime test = time2.ToUniversalTime(DateTime.Now);
var singapore = TimeZoneInfo.FindSystemTimeZoneById("Singapore Standard Time");
var singaporetime = TimeZoneInfo.ConvertTimeFromUtc(test, singapore);

Change the text to which standard time you want to change.

Use TimeZone feature of C# to implement.

The .getTimezoneOffset() method should work. This will get the time between your time zone and GMT. You can then calculate to whatever you want.

Assuming the UTC is not included in the string then:

date_default_timezone_set('America/New_York');
$datestring = '2011-01-01 15:00:00';  //Pulled in from somewhere
$date = date('Y-m-d H:i:s T',strtotime($datestring . ' UTC'));
echo $date;  //Should get '2011-01-01 10:00:00 EST' or something like that

Or you could use the DateTime object.

Please use DateTimeFormatter ISO_DATE_TIME = DateTimeFormatter.ISO_DATE_TIME; instead of DateTimeFormatter.ofPattern("dd-MM-yyyy HH:mm:ss") or any pattern

This fixed my problem Below

java.time.format.DateTimeParseException: Text '2019-12-18T19:00:00.000Z' could not be parsed at index 10

Simply SELECT @@system_time_zone;

Returns PST (or whatever is relevant to your system).

If you're trying to determine the session timezone you can use this query:
SELECT IF(@@session.time_zone = 'SYSTEM', @@system_time_zone, @@session.time_zone);

Which will return the session timezone if it differs from the system timezone.

You can access the timezone by the following script:

SELECT * FROM pg_timezone_names WHERE name = current_setting('TIMEZONE');

• current_setting('TIMEZONE') will give you Continent / Capital information of settings
• pg_timezone_names The view pg_timezone_names provides a list of time zone names that are recognized by SET TIMEZONE, along with their associated abbreviations, UTC offsets, and daylight-savings status.
• name column in a view (pg_timezone_names) is time zone name.

output will be :

name- Europe/Berlin, 
abbrev - CET, 
utc_offset- 01:00:00, 
is_dst- false

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

You can simply write your own code by using the mapping table here: http://www.timeanddate.com/time/zones/

or, use moment-timezone library: http://momentjs.com/timezone/docs/

See zone.name; // America/Los_Angeles

or, this library: https://github.com/Canop/tzdetect.js

You can pass the JVM this param

-Duser.timezone

For example

-Duser.timezone=Europe/Sofia

and this should do the trick. Setting the environment variable TZ also does the trick on Linux.

All the symptoms you describe suggest that you never tell MySQL what time zone to use so it defaults to system's zone. Think about it: if all it has is '2011-03-13 02:49:10', how can it guess that it's a local Tanzanian date?

As far as I know, MySQL doesn't provide any syntax to specify time zone information in dates. You have to change it a per-connection basis; something like:

SET time_zone = 'EAT';

If this doesn't work (to use named zones you need that the server has been configured to do so and it's often not the case) you can use UTC offsets because Tanzania does not observe daylight saving time at the time of writing but of course it isn't the best option:

SET time_zone = '+03:00';

To remove a timezone (tzinfo) from a datetime object:

# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)

If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.

# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime

# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)

Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime object to insert into the database. The solution is to convert your datetime.datetime object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime objects where one is timezone aware and another is timezone naive.

##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################

arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')

arrowDt = arrowObj.to("utc").datetime

# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)

# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()

# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3

# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True

As explained by others, there's a time discontinuity there. There are two possible timezone offsets for 1927-12-31 23:54:08 at Asia/Shanghai, but only one offset for 1927-12-31 23:54:07. So, depending on which offset is used, there's either a one second difference or a 5 minutes and 53 seconds difference.

This slight shift of offsets, instead of the usual one-hour daylight savings (summer time) we are used to, obscures the problem a bit.

Note that the 2013a update of the timezone database moved this discontinuity a few seconds earlier, but the effect would still be observable.

The new java.time package on Java 8 let use see this more clearly, and provide tools to handle it. Given:

DateTimeFormatterBuilder dtfb = new DateTimeFormatterBuilder();
dtfb.append(DateTimeFormatter.ISO_LOCAL_DATE);
dtfb.appendLiteral(' ');
dtfb.append(DateTimeFormatter.ISO_LOCAL_TIME);
DateTimeFormatter dtf = dtfb.toFormatter();
ZoneId shanghai = ZoneId.of("Asia/Shanghai");

String str3 = "1927-12-31 23:54:07";  
String str4 = "1927-12-31 23:54:08";  

ZonedDateTime zdt3 = LocalDateTime.parse(str3, dtf).atZone(shanghai);
ZonedDateTime zdt4 = LocalDateTime.parse(str4, dtf).atZone(shanghai);

Duration durationAtEarlierOffset = Duration.between(zdt3.withEarlierOffsetAtOverlap(), zdt4.withEarlierOffsetAtOverlap());

Duration durationAtLaterOffset = Duration.between(zdt3.withLaterOffsetAtOverlap(), zdt4.withLaterOffsetAtOverlap());

Then durationAtEarlierOffset will be one second, while durationAtLaterOffset will be five minutes and 53 seconds.

Also, these two offsets are the same:

// Both have offsets +08:05:52
ZoneOffset zo3Earlier = zdt3.withEarlierOffsetAtOverlap().getOffset();
ZoneOffset zo3Later = zdt3.withLaterOffsetAtOverlap().getOffset();

But these two are different:

// +08:05:52
ZoneOffset zo4Earlier = zdt4.withEarlierOffsetAtOverlap().getOffset();

// +08:00
ZoneOffset zo4Later = zdt4.withLaterOffsetAtOverlap().getOffset();

You can see the same problem comparing 1927-12-31 23:59:59 with 1928-01-01 00:00:00, though, in this case, it is the earlier offset that produces the longer divergence, and it is the earlier date that has two possible offsets.

Another way to approach this is to check whether there's a transition going on. We can do this like this:

// Null
ZoneOffsetTransition zot3 = shanghai.getRules().getTransition(ld3.toLocalDateTime);

// An overlap transition
ZoneOffsetTransition zot4 = shanghai.getRules().getTransition(ld3.toLocalDateTime);

You can check whether the transition is an overlap where there's more than one valid offset for that date/time or a gap where that date/time is not valid for that zone id - by using the isOverlap() and isGap() methods on zot4.

I hope this helps people handle this sort of issue once Java 8 becomes widely available, or to those using Java 7 who adopt the JSR 310 backport.

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

DateTimeFormatter formatter = DateTimeFormatter.ISO_ZONED_DATE_TIME;

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

Be aware that running

import os
os.system("tzutil /s \"Central Standard Time\"");

will alter Windows system time, NOT just the local python environment time (so is definitley NOT the same as:

>>> os.environ['TZ'] = 'Europe/London'
>>> time.tzset()

which will only set in the current environment time (in Unix only)

Most browsers support the toLocaleString function with arguments, older browsers usually ignore the arguments.

const str = new Date().toLocaleString('en-US', { timeZone: 'Asia/Jakarta' });
console.log(str);

Your time string is similar to the time format in rfc 2822 (date format in email, http headers). You could parse it using only stdlib:

>>> from email.utils import parsedate_tz
>>> parsedate_tz('Tue Jun 22 07:46:22 EST 2010')
(2010, 6, 22, 7, 46, 22, 0, 1, -1, -18000)

See solutions that yield timezone-aware datetime objects for various Python versions: parsing date with timezone from an email.

In this format, EST is semantically equivalent to -0500. Though, in general, a timezone abbreviation is not enough, to identify a timezone uniquely.

I wrote something like this the other day:

import time, datetime
def nowString():
    # we want something like '2007-10-18 14:00+0100'
    mytz="%+4.4d" % (time.timezone / -(60*60) * 100) # time.timezone counts westwards!
    dt  = datetime.datetime.now()
    dts = dt.strftime('%Y-%m-%d %H:%M')  # %Z (timezone) would be empty
    nowstring="%s%s" % (dts,mytz)
    return nowstring

So the interesting part for you is probably the line starting with "mytz=...". time.timezone returns the local timezone, albeit with opposite sign compared to UTC. So it says "-3600" to express UTC+1.

Despite its ignorance towards Daylight Saving Time (DST, see comment), I'm leaving this in for people fiddling around with time.timezone.

if you want to check the difference in a time between two dates, you can simply check if second timezone is lesser or greater from your first desired timezone and subtract or add a time.

  const currTimezone = new Date().getTimezoneOffset(); // your timezone
  const newDateTimezone = date.getTimezoneOffset(); // date with unknown timezone

  if (currTimezone !== newDateTimezone) {
    // and below you are checking if difference should be - or +. It depends on if unknown timezone is lesser or greater than yours
    const newTimezone = (currTimezone - newDateTimezone) * (currTimezone > newDateTimezone ? 1 : -1);
    date.setTime(date.getTime() + (newTimezone * 60 * 1000));
  }

I have a suspicion, that the Answer doesn't give the correct result. In the question the asker wants to convert timestamp from server to current time in Hellsinki disregarding current time zone of the user.

It's the fact that the user's timezone can be what ever so we cannot trust to it.

If eg. timestamp is 1270544790922 and we have a function:

var _date = new Date();
_date.setTime(1270544790922);
var _helsenkiOffset = 2*60*60;//maybe 3
var _userOffset = _date.getTimezoneOffset()*60*60; 
var _helsenkiTime = new Date(_date.getTime()+_helsenkiOffset+_userOffset);

When a New Yorker visits the page, alert(_helsenkiTime) prints:

Tue Apr 06 2010 05:21:02 GMT-0400 (EDT)

And when a Finlander visits the page, alert(_helsenkiTime) prints:

Tue Apr 06 2010 11:55:50 GMT+0300 (EEST)

So the function is correct only if the page visitor has the target timezone (Europe/Helsinki) in his computer, but fails in nearly every other part of the world. And because the server timestamp is usually UNIX timestamp, which is by definition in UTC, the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT), we cannot determine DST or non-DST from timestamp.

So the solution is to DISREGARD the current time zone of the user and implement some way to calculate UTC offset whether the date is in DST or not. Javascript has not native method to determine DST transition history of other timezone than the current timezone of user. We can achieve this most simply using server side script, because we have easy access to server's timezone database with the whole transition history of all timezones.

But if you have no access to the server's (or any other server's) timezone database AND the timestamp is in UTC, you can get the similar functionality by hard coding the DST rules in Javascript.

To cover dates in years 1998 - 2099 in Europe/Helsinki you can use the following function (jsfiddled):

function timestampToHellsinki(server_timestamp) {
    function pad(num) {
        num = num.toString();
        if (num.length == 1) return "0" + num;
        return num;
    }

    var _date = new Date();
    _date.setTime(server_timestamp);

    var _year = _date.getUTCFullYear();

    // Return false, if DST rules have been different than nowadays:
    if (_year<=1998 && _year>2099) return false;

    // Calculate DST start day, it is the last sunday of March
    var start_day = (31 - ((((5 * _year) / 4) + 4) % 7));
    var SUMMER_start = new Date(Date.UTC(_year, 2, start_day, 1, 0, 0));

    // Calculate DST end day, it is the last sunday of October
    var end_day = (31 - ((((5 * _year) / 4) + 1) % 7))
    var SUMMER_end = new Date(Date.UTC(_year, 9, end_day, 1, 0, 0));

    // Check if the time is between SUMMER_start and SUMMER_end
    // If the time is in summer, the offset is 2 hours
    // else offset is 3 hours
    var hellsinkiOffset = 2 * 60 * 60 * 1000;
    if (_date > SUMMER_start && _date < SUMMER_end) hellsinkiOffset = 
    3 * 60 * 60 * 1000;

    // Add server timestamp to midnight January 1, 1970
    // Add Hellsinki offset to that
    _date.setTime(server_timestamp + hellsinkiOffset);
    var hellsinkiTime = pad(_date.getUTCDate()) + "." + 
    pad(_date.getUTCMonth()) + "." + _date.getUTCFullYear() + 
    " " + pad(_date.getUTCHours()) + ":" +
    pad(_date.getUTCMinutes()) + ":" + pad(_date.getUTCSeconds());

    return hellsinkiTime;
}

Examples of usage:

var server_timestamp = 1270544790922;
document.getElementById("time").innerHTML = "The timestamp " + 
server_timestamp + " is in Hellsinki " + 
timestampToHellsinki(server_timestamp);

server_timestamp = 1349841923 * 1000;
document.getElementById("time").innerHTML += "<br><br>The timestamp " + 
server_timestamp + " is in Hellsinki " + timestampToHellsinki(server_timestamp);

var now = new Date();
server_timestamp = now.getTime();
document.getElementById("time").innerHTML += "<br><br>The timestamp is now " +
server_timestamp + " and the current local time in Hellsinki is " +
timestampToHellsinki(server_timestamp);?

And this print the following regardless of user timezone:

The timestamp 1270544790922 is in Hellsinki 06.03.2010 12:06:30

The timestamp 1349841923000 is in Hellsinki 10.09.2012 07:05:23

The timestamp is now 1349853751034 and the current local time in Hellsinki is 10.09.2012 10:22:31

Of course if you can return timestamp in a form that the offset (DST or non-DST one) is already added to timestamp on server, you don't have to calculate it clientside and you can simplify the function a lot. BUT remember to NOT use timezoneOffset(), because then you have to deal with user timezone and this is not the wanted behaviour.

I should like to provide the modern answer.

You shouldn’t really want to convert a date and time from a string at one GMT offset to a string at a different GMT offset and with in a different format. Rather in your program keep an instant (a point in time) as a proper date-time object. Only when you need to give string output, format your object into the desired string.

java.time

Parsing input

    DateTimeFormatter formatter = new DateTimeFormatterBuilder()
            .append(DateTimeFormatter.ISO_LOCAL_DATE)
            .appendLiteral(' ')
            .append(DateTimeFormatter.ISO_LOCAL_TIME)
            .toFormatter();

    String dateTimeString = "2011-10-06 03:35:05";
    Instant instant = LocalDateTime.parse(dateTimeString, formatter)
            .atOffset(ZoneOffset.UTC)
            .toInstant();

For most purposes Instant is a good choice for storing a point in time. If you needed to make it explicit that the date and time came from GMT, use an OffsetDateTime instead.

Converting, formatting and printing output

    ZoneId desiredZone = ZoneId.of("Pacific/Auckland");
    Locale desiredeLocale = Locale.forLanguageTag("en-NZ");
    DateTimeFormatter desiredFormatter = DateTimeFormatter.ofPattern(
            "dd MMM uuuu HH:mm:ss OOOO", desiredeLocale);

    ZonedDateTime desiredDateTime = instant.atZone(desiredZone);
    String result = desiredDateTime.format(desiredFormatter);
    System.out.println(result);

This printed:

06 Oct 2011 16:35:05 GMT+13:00

I specified time zone Pacific/Auckland rather than the offset you mentioned, +13:00. I understood that you wanted New Zealand time, and Pacific/Auckland better tells the reader this. The time zone also takes summer time (DST) into account so you don’t need to take this into account in your own code (for most purposes).

Since Oct is in English, it’s a good idea to give the formatter an explicit locale. GMT might be localized too, but I think that it just prints GMT in all locales.

OOOO in the format patterns string is one way of printing the offset, which may be a better idea than printing the time zone abbreviation you would get from z since time zone abbreviations are often ambiguous. If you want NZDT (for New Zealand Daylight Time), just put z there instead.

Your questions

I will answer your numbered questions in relation to the modern classes in java.time.

Is possible to:

1. Set the time on an object

No, the modern classes are immutable. You need to create an object that has the desired date and time from the outset (this has a number of advantages including thread safety).

2. (Possibly) Set the TimeZone of the initial time stamp

The atZone method that I use in the code returns a ZonedDateTime with the specified time zone. Other date-time classes have a similar method, sometimes called atZoneSameInstant or other names.

3. Format the time stamp with a new TimeZone

With java.time converting to a new time zone and formatting are two distinct steps as shown.

4. Return a string with new time zone time.

Yes, convert to the desired time zone as shown and format as shown.

I found that anytime I try to set the time like this:

calendar.setTime(new Date(1317816735000L));

the local machine's TimeZone is used. Why is that?

It’s not the way you think, which goes nicely to show just a couple of the (many) design problems with the old classes.

• A Date hasn’t got a time zone. Only when you print it, its toString method grabs your local time zone and uses it for rendering the string. This is true for new Date() too. This behaviour has confused many, many programmers over the last 25 years.
• A Calender has got a time zone. It doesn’t change when you do calendar.setTime(new Date(1317816735000L));.

Oracle tutorial: Date Time explaining how to use java.time.

-new Date().getTimezoneOffset()/60;

The method getTimezoneOffset() will subtract your time from GMT and return the number of minutes. So if you live in GMT-8, it will return 480.

To put this into hours, divide by 60. Also, notice that the sign is the opposite of what you need - it's calculating GMT's offset from your time zone, not your time zone's offset from GMT. To fix this, simply multiply by -1.

Also note that w3school says:

The returned value is not a constant, because of the practice of using Daylight Saving Time.

TLDR if you don't want to read all these great answers :-)

Explicit:

Using DateTimeOffset because the timezone is forced to UTC+0.

Implicit:

Using DateTime where you hope everyone sticks to the unwritten rule of the timezone always being UTC+0.

(Side note for devs: explicit is always better than implicit!)

(Side side note for Java devs, C# DateTimeOffset == Java OffsetDateTime, read this: https://www.baeldung.com/java-zoneddatetime-offsetdatetime)

Thank you all for responding. After a further investigation I got to the right answer. As mentioned by Skip Head, the TimeStamped I was getting from my application was being adjusted to the user's TimeZone. So if the User entered 6:12 PM (EST) I would get 2:12 PM (GMT). What I needed was a way to undo the conversion so that the time entered by the user is the time I sent to the WebServer request. Here's how I accomplished this:

// Get TimeZone of user
TimeZone currentTimeZone = sc_.getTimeZone();
Calendar currentDt = new GregorianCalendar(currentTimeZone, EN_US_LOCALE);
// Get the Offset from GMT taking DST into account
int gmtOffset = currentTimeZone.getOffset(
    currentDt.get(Calendar.ERA), 
    currentDt.get(Calendar.YEAR), 
    currentDt.get(Calendar.MONTH), 
    currentDt.get(Calendar.DAY_OF_MONTH), 
    currentDt.get(Calendar.DAY_OF_WEEK), 
    currentDt.get(Calendar.MILLISECOND));
// convert to hours
gmtOffset = gmtOffset / (60*60*1000);
System.out.println("Current User's TimeZone: " + currentTimeZone.getID());
System.out.println("Current Offset from GMT (in hrs):" + gmtOffset);
// Get TS from User Input
Timestamp issuedDate = (Timestamp) getACPValue(inputs_, "issuedDate");
System.out.println("TS from ACP: " + issuedDate);
// Set TS into Calendar
Calendar issueDate = convertTimestampToJavaCalendar(issuedDate);
// Adjust for GMT (note the offset negation)
issueDate.add(Calendar.HOUR_OF_DAY, -gmtOffset);
System.out.println("Calendar Date converted from TS using GMT and US_EN Locale: "
    + DateFormat.getDateTimeInstance(DateFormat.SHORT, DateFormat.SHORT)
    .format(issueDate.getTime()));

The code's output is: (User entered 5/1/2008 6:12PM (EST)

Current User's TimeZone: EST
Current Offset from GMT (in hrs):-4 (Normally -5, except is DST adjusted)
TS from ACP: 2008-05-01 14:12:00.0
Calendar Date converted from TS using GMT and US_EN Locale: 5/1/08 6:12 PM (GMT)

Here's what I've used in past projects:

var myDate = new Date();
var tzo = (myDate.getTimezoneOffset()/60)*(-1);
//get server date value here, the parseInvariant is from MS Ajax, you would need to do something similar on your own
myDate = new Date.parseInvariant('<%=DataCurrentDate%>', 'yyyyMMdd hh:mm:ss');
myDate.setHours(myDate.getHours() + tzo);
//here you would have to get a handle to your span / div to set.  again, I'm using MS Ajax's $get
var dateSpn = $get('dataDate');
dateSpn.innerHTML = myDate.localeFormat('F');

If you want a one liner, The UTC Unix Timestamp can be created in JavaScript as:

var currentUnixTimestap = ~~(+new Date() / 1000);

This will take in account the timezone of the system. It is basically time elapsed in Seconds since epoch.

How it works:

• Create date object : new Date().
• Convert to timestamp by adding unary + before object creation to convert it to timestamp integer. : +new Date().
• Convert milliseconds to seconds: +new Date() / 1000
• Use double tildes to round off the value to integer. : ~~(+new Date())

You probably need to put the timezone in a configuration line in your php.ini file. You should have a block like this in your php.ini file:

[Date]
; Defines the default timezone used by the date functions
; http://php.net/date.timezone
date.timezone = America/New_York

If not, add it (replacing the timezone by yours). After configuring, make sure to restart httpd (service httpd restart).

Here is the list of supported timezones.

Here I am sharing the script, convert UTC timestamp to Indian timestamp:-

    // create a $utc object with the UTC timezone
    $IST = new DateTime('2016-12-12 12:12:12', new DateTimeZone('UTC'));

    // change the timezone of the object without changing it's time
    $IST->setTimezone(new DateTimeZone('Asia/Kolkata'));

    // format the datetime
   echo $IST->format('Y-m-d H:i:s T');

Use DateFormat. For example,

SimpleDateFormat isoFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss");
isoFormat.setTimeZone(TimeZone.getTimeZone("UTC"));
Date date = isoFormat.parse("2010-05-23T09:01:02");

Append 'UTC' to the string before converting it to a date in javascript:

var date = new Date('6/29/2011 4:52:48 PM UTC');
date.toString() // "Wed Jun 29 2011 09:52:48 GMT-0700 (PDT)"

For fitting y = A + B log x, just fit y against (log x).

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> numpy.polyfit(numpy.log(x), y, 1)
array([ 8.46295607,  6.61867463])
# y ˜ 8.46 log(x) + 6.62

For fitting y = Ae^Bx, take the logarithm of both side gives log y = log A + Bx. So fit (log y) against x.

Note that fitting (log y) as if it is linear will emphasize small values of y, causing large deviation for large y. This is because polyfit (linear regression) works by minimizing ?_i (?Y)² = ?_i (Y_i − Y_i)². When Y_i = log y_i, the residues ?Y_i = ?(log y_i) ˜ ?y_i / |y_i|. So even if polyfit makes a very bad decision for large y, the "divide-by-|y|" factor will compensate for it, causing polyfit favors small values.

This could be alleviated by giving each entry a "weight" proportional to y. polyfit supports weighted-least-squares via the w keyword argument.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> numpy.polyfit(x, numpy.log(y), 1)
array([ 0.10502711, -0.40116352])
#    y ˜ exp(-0.401) * exp(0.105 * x) = 0.670 * exp(0.105 * x)
# (^ biased towards small values)
>>> numpy.polyfit(x, numpy.log(y), 1, w=numpy.sqrt(y))
array([ 0.06009446,  1.41648096])
#    y ˜ exp(1.42) * exp(0.0601 * x) = 4.12 * exp(0.0601 * x)
# (^ not so biased)

Note that Excel, LibreOffice and most scientific calculators typically use the unweighted (biased) formula for the exponential regression / trend lines. If you want your results to be compatible with these platforms, do not include the weights even if it provides better results.

Now, if you can use scipy, you could use scipy.optimize.curve_fit to fit any model without transformations.

For y = A + B log x the result is the same as the transformation method:

>>> x = numpy.array([1, 7, 20, 50, 79])
>>> y = numpy.array([10, 19, 30, 35, 51])
>>> scipy.optimize.curve_fit(lambda t,a,b: a+b*numpy.log(t),  x,  y)
(array([ 6.61867467,  8.46295606]), 
 array([[ 28.15948002,  -7.89609542],
        [ -7.89609542,   2.9857172 ]]))
# y ˜ 6.62 + 8.46 log(x)

For y = Ae^Bx, however, we can get a better fit since it computes ?(log y) directly. But we need to provide an initialize guess so curve_fit can reach the desired local minimum.

>>> x = numpy.array([10, 19, 30, 35, 51])
>>> y = numpy.array([1, 7, 20, 50, 79])
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y)
(array([  5.60728326e-21,   9.99993501e-01]),
 array([[  4.14809412e-27,  -1.45078961e-08],
        [ -1.45078961e-08,   5.07411462e+10]]))
# oops, definitely wrong.
>>> scipy.optimize.curve_fit(lambda t,a,b: a*numpy.exp(b*t),  x,  y,  p0=(4, 0.1))
(array([ 4.88003249,  0.05531256]),
 array([[  1.01261314e+01,  -4.31940132e-02],
        [ -4.31940132e-02,   1.91188656e-04]]))
# y ˜ 4.88 exp(0.0553 x). much better.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

this.dataSource = new MatTableDataSource<Element>(this.elements);

Add this line below your action of add or delete the particular row.

refresh() {
  this.authService.getAuthenticatedUser().subscribe((res) => {
    this.user = new MatTableDataSource<Element>(res);   
  });
}

You can also use Bash on Ubuntu on Windows directly. E.g.,

bash -c "ssh -t user@computer 'cd /; sudo my-command'"

Per Martin Prikryl's comment below:

The -t enables terminal emulation. Whether you need the terminal emulation for sudo depends on configuration (and by default you do no need it, while many distributions override the default). On the contrary, many other commands need terminal emulation.

You could do it easily using

File.AppendAllText("date.txt", DateTime.Now.ToString());

If you need newline

File.AppendAllText("date.txt", 
                   DateTime.Now.ToString() + Environment.NewLine);

Anyway if you need your code do this:

TextWriter tw = new StreamWriter("date.txt", true);

with second parameter telling to append to file.
Check here StreamWriter syntax.

You can set min-width property of CSS for body tag. Since this property is not supported by IE6, you can write like:

body{
   min-width:1000px;        /* Suppose you want minimum width of 1000px */
   width: auto !important;  /* Firefox will set width as auto */
   width:1000px;            /* As IE6 ignores !important it will set width as 1000px; */
}

Or:

body{
   min-width:1000px; // Suppose you want minimum width of 1000px
   _width: expression( document.body.clientWidth > 1000 ? "1000px" : "auto" ); /* sets max-width for IE6 */
}

Static classes are very useful and have a place, for example libraries.

The best example I can provide is the .Net Math class, a System namespace static class that contains a library of maths functions.

It is like anything else, use the right tool for the job, and if not anything can be abused.

Blankly dismissing static classes as wrong, don't use them, or saying "there can be only one" or none, is as wrong as over using the them.

C#.Net contains a number of static classes that is uses just like the Math class.

So given the correct implementation they are tremendously useful.

We have a static TimeZone class that contains a number of business related timezone functions, there is no need to create multiple instances of the class so much like the Math class it contains a set of globally accesible TimeZone realated functions (methods) in a static class.

No, you can't achieve that without setting a fixed height (or using a script).

Here are 2 answers of mine, showing how to use a script to achieve something like that:

• How to get header from cards or similar to have the same height with flex box?

• Same height for flex items in the flex-direction column flex container

First think of a solution without code. The idea is to print an odd number of *, increasing by line. Then center the * by using spaces. Knowing the max number of * in the last line, will give you the initial number of spaces to center the first *. Now write it in code.

a = sin²(?f/2) + cos f1 · cos f2 · sin²(??/2)

c = 2 · atan2( va, v(1-a) )

distance = R · c

where f is latitude, ? is longitude, R is earth’s radius (mean radius = 6,371km);

note that angles need to be in radians to pass to trig functions!

fun distanceInMeter(firstLocation: Location, secondLocation: Location): Double {
    val earthRadius = 6371000.0
    val deltaLatitudeDegree = (firstLocation.latitude - secondLocation.latitude) * Math.PI / 180f
    val deltaLongitudeDegree = (firstLocation.longitude - secondLocation.longitude) * Math.PI / 180f
    val a = sin(deltaLatitudeDegree / 2).pow(2) +
            cos(firstLocation.latitude * Math.PI / 180f) * cos(secondLocation.latitude * Math.PI / 180f) *
            sin(deltaLongitudeDegree / 2).pow(2)
    val c = 2f * atan2(sqrt(a), sqrt(1 - a))
    return earthRadius * c
}


data class Location(val latitude: Double, val longitude: Double)

Switching to another branch in git. Straightforward answer,

git-checkout - Switch branches or restore working tree files

git fetch origin         <----this will fetch the branch
git checkout branch_name <--- Switching the branch

Before switching the branch make sure you don't have any modified files, in that case, you can commit the changes or you can stash it.

You can get the first column as a Series by following code:

x[x.columns[0]]

Why not just doing it this way?

DateTime dt1 = new DateTime(2009, 6, 1);
DateTime dt2 = DateTime.Now;
double totalminutes = (dt2 - dt1).TotalMinutes;

Hope this helps.

I'm late to the show, but if you're testing a field, you can use getGenericType:

import static org.junit.Assert.*;

import java.lang.reflect.Field;
import java.lang.reflect.Type;
import java.util.Arrays;
import java.util.Collection;
import java.util.HashSet;

import org.junit.Test;

public class PrimitiveVsObjectTest {

    private static final Collection<String> PRIMITIVE_TYPES = 
            new HashSet<>(Arrays.asList("byte", "short", "int", "long", "float", "double", "boolean", "char"));

    private static boolean isPrimitive(Type type) {
        return PRIMITIVE_TYPES.contains(type.getTypeName());
    }

    public int i1 = 34;
    public Integer i2 = 34;

    @Test
    public void primitive_type() throws NoSuchFieldException, SecurityException {
        Field i1Field = PrimitiveVsObjectTest.class.getField("i1");
        Type genericType1 = i1Field.getGenericType();
        assertEquals("int", genericType1.getTypeName());
        assertNotEquals("java.lang.Integer", genericType1.getTypeName());
        assertTrue(isPrimitive(genericType1));
    }

    @Test
    public void object_type() throws NoSuchFieldException, SecurityException {
        Field i2Field = PrimitiveVsObjectTest.class.getField("i2");
        Type genericType2 = i2Field.getGenericType();
        assertEquals("java.lang.Integer", genericType2.getTypeName());
        assertNotEquals("int", genericType2.getTypeName());
        assertFalse(isPrimitive(genericType2));
    }
}

The Oracle docs list the 8 primitive types.

Events are pretty easy in C#, but the MSDN docs in my opinion make them pretty confusing. Normally, most documentation you see discusses making a class inherit from the EventArgs base class and there's a reason for that. However, it's not the simplest way to make events, and for someone wanting something quick and easy, and in a time crunch, using the Action type is your ticket.

Creating Events & Subscribing To Them

1. Create your event on your class right after your class declaration.

public event Action<string,string,string,string>MyEvent;

2. Create your event handler class method in your class.

private void MyEventHandler(string s1,string s2,string s3,string s4)
{
  Console.WriteLine("{0} {1} {2} {3}",s1,s2,s3,s4);
}

3. Now when your class is invoked, tell it to connect the event to your new event handler. The reason the += operator is used is because you are appending your particular event handler to the event. You can actually do this with multiple separate event handlers, and when an event is raised, each event handler will operate in the sequence in which you added them.

class Example
{
  public Example() // I'm a C# style class constructor
  {
    MyEvent += new Action<string,string,string,string>(MyEventHandler);
  }
}

4. Now, when you're ready, trigger (aka raise) the event somewhere in your class code like so:

MyEvent("wow","this","is","cool");

The end result when you run this is that the console will emit "wow this is cool". And if you changed "cool" with a date or a sequence, and ran this event trigger multiple times, you'd see the result come out in a FIFO sequence like events should normally operate.

In this example, I passed 4 strings. But you could change those to any kind of acceptable type, or used more or less types, or even remove the <...> out and pass nothing to your event handler.

And, again, if you had multiple custom event handlers, and subscribed them all to your event with the += operator, then your event trigger would have called them all in sequence.

Identifying Event Callers

But what if you want to identify the caller to this event in your event handler? This is useful if you want an event handler that reacts with conditions based on who's raised/triggered the event. There are a few ways to do this. Below are examples that are shown in order by how fast they operate:

Option 1. (Fastest) If you already know it, then pass the name as a literal string to the event handler when you trigger it.

Option 2. (Somewhat Fast) Add this into your class and call it from the calling method, and then pass that string to the event handler when you trigger it:

private static string GetCaller([System.Runtime.CompilerServices.CallerMemberName] string s = null) => s;

Option 3. (Least Fast But Still Fast) In your event handler when you trigger it, get the calling method name string with this:

string callingMethod = new System.Diagnostics.StackTrace().GetFrame(1).GetMethod().ReflectedType.Name.Split('<', '>')[1];

Unsubscribing From Events

You may have a scenario where your custom event has multiple event handlers, but you want to remove one special one out of the list of event handlers. To do so, use the -= operator like so:

MyEvent -= MyEventHandler;

A word of minor caution with this, however. If you do this and that event no longer has any event handlers, and you trigger that event again, it will throw an exception. (Exceptions, of course, you can trap with try/catch blocks.)

Clearing All Events

Okay, let's say you're through with events and you don't want to process any more. Just set it to null like so:

MyEvent = null;

The same caution for Unsubscribing events is here, as well. If your custom event handler no longer has any events, and you trigger it again, your program will throw an exception.

JAX-RS implementations automatically support marshalling/unmarshalling of classes based on discoverable JAXB annotations, but because your payload is declared as Object, I think the created JAXBContext misses the Department class and when it's time to marshall it it doesn't know how.

A quick and dirty fix would be to add a XmlSeeAlso annotation to your response class:

@XmlRootElement
@XmlSeeAlso({Department.class})
public class Response implements Serializable {
  ....

or something a little more complicated would be "to enrich" the JAXB context for the Response class by using a ContextResolver:

import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.ext.ContextResolver;
import javax.ws.rs.ext.Provider;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;

@Provider
@Produces({ MediaType.APPLICATION_JSON, MediaType.APPLICATION_XML })
public class ResponseResolver implements ContextResolver<JAXBContext> {
    private JAXBContext ctx;

    public ResponseResolver() {
        try {
            this.ctx = JAXBContext.newInstance(

                        Response.class, 
                        Department.class

                    );
        } catch (JAXBException ex) {
            throw new RuntimeException(ex);
        }
    }

    public JAXBContext getContext(Class<?> type) {
        return (type.equals(Response.class) ? ctx : null);
    }
}

The answer may be language dependent, but since you don't mention one, here is what I just came up with in js:

 var a = ['1','','2','','3'].join('\n');

 console.log(a.match(/^.{0}$/gm)); // ["", ""]

 // the "." is for readability. it doesn't really matter
 a.match(/^[you can put whatever the hell you want and this will also work just the same]{0}$/gm)

You could also do a.match(/^(.{10,}|.{0})$/gm) to match empty lines OR lines that meet a criteria. (This is what I was looking for to end up here.)

I know that ^ will match the beginning of any line and $ will match the end of any line

This is only true if you have the multiline flag turned on, otherwise it will only match the beginning/end of the string. I'm assuming you know this and are implying that, but wanted to note it here for learners.

This occurs when you try and write to a file that is currently being executed by the kernel, or execute a file that is currently open for writing.

To static either a row or a column, put a $ sign in front of it. So if you were to use the formula =AVERAGE($A1,$C1) and drag it down the entire sheet, A and C would remain static while the 1 would change to the current row

If you're on Windows, you can achieve the same thing by repeatedly pressing F4 while in the formula editing bar. The first F4 press will static both (it will turn A1 into $A$1), then just the row (A$1) then just the column ($A1)

Although technically with the formulas that you have, dragging down for the entirety of the column shouldn't be a problem without putting a $ sign in front of the column. Setting the column as static would only come into play if you're dragging ACROSS columns and want to keep using the same column, and setting the row as static would be for dragging down rows but wanting to use the same row.

My problem is multi modules project with base module, app module and feature module. Each module has AndroidManifest of its own, and I implemented build variant for debug and main. So we must sure that "android:name" just declared in Manifest of debug and main only, and do not set it in any of Manifest in child module. Ex: Manifest in main:

 <application
        android:name=".App"/>

Manifest in debug:

<application
        tools:replace="android:name"
        android:name=".DebugApp"
        />

Do not set "android:name" in other Manifest files like this:

<application android:name=".App">

Just define in feature module like this and it will merged fine

<application> 

I suspect you are having a problem with factors. For example,

> x = factor(4:8)
> x
[1] 4 5 6 7 8
Levels: 4 5 6 7 8
> as.numeric(x)
[1] 1 2 3 4 5
> as.numeric(as.character(x))
[1] 4 5 6 7 8

Some comments:

• You mention that your vector contains the characters "Down" and "NoData". What do expect/want as.numeric to do with these values?
• In read.csv, try using the argument stringsAsFactors=FALSE
• Are you sure it's sep="/t and not sep="\t"
• Use the command head(pitchman) to check the first fews rows of your data
• Also, it's very tricky to guess what your problem is when you don't provide data. A minimal working example is always preferable. For example, I can't run the command pichman <- read.csv(file="picman.txt", header=TRUE, sep="/t") since I don't have access to the data set.

This is specific for each site. So if you type that once, you will only get through that site and all other sites will need a similar type-through.

It is also remembered for that site and you have to click on the padlock to reset it (so you can type it again):

Needless to say use of this "feature" is a bad idea and is unsafe - hence the name.

You should find out why the site is showing the error and/or stop using it until they fix it. HSTS specifically adds protections for bad certs to prevent you clicking through them. The fact it's needed suggests there is something wrong with the https connection - like the site or your connection to it has been hacked.

The chrome developers also do change this periodically. They changed it recently from badidea to thisisunsafe so everyone using badidea, suddenly stopped being able to use it. You should not depend on it. As Steffen pointed out in the comments below, it is available in the code should it change again though they now base64 encode it to make it more obscure. The last time they changed they put this comment in the commit:

Rotate the interstitial bypass keyword

The security interstitial bypass keyword hasn't changed in two years and awareness of the bypass has been increased in blogs and social media. Rotate the keyword to help prevent misuse.

I think the message from the Chrome team is clear - you should not use it. It would not surprise me if they removed it completely in future.

If you are using this when using a self-signed certificate for local testing then why not just add your self-signed certificate certificate to your computer's certificate store so you get a green padlock and do not have to type this? Note Chrome insists on a SAN field in certificates now so if just using the old subject field then even adding it to the certificate store will not result in a green padlock.

If you leave the certificate untrusted then certain things do not work. Caching for example is completely ignored for untrusted certificates. As is HTTP/2 Push.

HTTPS is here to stay and we need to get used to using it properly - and not bypassing the warnings with a hack that is liable to change and doesn't work the same as a full HTTPS solution.

Save it as a CSV file and import it as a flat source file.

ListView myListView = (ListView) rootView.findViewById(R.id.myListView);
ArrayList<String> myStringArray1 = new ArrayList<String>();
myStringArray1.add("something");
adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
myListView.setAdapter(adapter);

Try it like this

public OnClickListener moreListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
        adapter = null;
        myStringArray1.add("Andrea");
        adapter = new CustomAdapter(getActivity(), R.layout.row, myStringArray1);
        myListView.setAdapter(adapter);
        adapter.notifyDataSetChanged();
    }       
};

The way to reinstall Homebrew is completely remove it and start over. The Homebrew FAQ has a link to a shell script to uninstall homebrew.

If the only thing you've installed in /usr/local is homebrew itself, you can just rm -rf /usr/local/* /usr/local/.git to clear it out. But /usr/local/ is the standard Unix directory for all extra binaries, not just Homebrew, so you may have other things installed there. In that case uninstall_homebrew.sh is a better bet. It is careful to only remove homebrew's files and leave the rest alone.

This is what I used to print text to a canvas. The input is not coming from a textarea, but from input and I'm only splitting by space. Definitely not perfect, but works for my case. It returns the lines in an array:

splitTextToLines: function (text) {
        var idealSplit = 7,
            maxSplit = 20,
            lineCounter = 0,
            lineIndex = 0,
            lines = [""],
            ch, i;

        for (i = 0; i < text.length; i++) {
            ch = text[i];
            if ((lineCounter >= idealSplit && ch === " ") || lineCounter >= maxSplit) {
                ch = "";
                lineCounter = -1;
                lineIndex++;
                lines.push("");
            }
            lines[lineIndex] += ch;
            lineCounter++;
        }

        return lines;
    }

This way works and with this structure you can create your own framework and do it with less boilerplate.

Adding a branch option in .gitmodule is NOT related to the detached behavior of submodules at all. The old answer from @mkungla is incorrect, or obsolete.

From git submodule --help, HEAD detached is the default behavior of git submodule update --remote.

First, there's no need to specify a branch to be tracked. origin/master is the default branch to be tracked.

--remote

Instead of using the superproject's recorded SHA-1 to update the submodule, use the status of the submodule's remote-tracking branch. The remote used is branch's remote (branch.<name>.remote), defaulting to origin. The remote branch used defaults to master.

Why

So why is HEAD detached after update? This is caused by the default module update behavior: checkout.

--checkout

Checkout the commit recorded in the superproject on a detached HEAD in the submodule. This is the default behavior, the main use of this option is to override submodule.$name.update when set to a value other than checkout.

To explain this weird update behavior, we need to understand how do submodules work?

Quote from Starting with Submodules in book Pro Git

Although sbmodule DbConnector is a subdirectory in your working directory, Git sees it as a submodule and doesn’t track its contents when you’re not in that directory. Instead, Git sees it as a particular commit from that repository.

The main repo tracks the submodule with its state at a specific point, the commit id. So when you update modules, you're updating the commit id to a new one.

How

If you want the submodule merged with remote branch automatically, use --merge or --rebase.

--merge

This option is only valid for the update command. Merge the commit recorded in the superproject into the current branch of the submodule. If this option is given, the submodule's HEAD will not be detached.

--rebase

Rebase the current branch onto the commit recorded in the superproject. If this option is given, the submodule's HEAD will not be detached.

All you need to do is,

git submodule update --remote --merge
# or
git submodule update --remote --rebase

Recommended alias:

git config alias.supdate 'submodule update --remote --merge'

# do submodule update with
git supdate

There's also an option to make --merge or --rebase as the default behavior of git submodule update, by setting submodule.$name.update to merge or rebase.

Here's an example about how to config the default update behavior of submodule update in .gitmodule.

[submodule "bash/plugins/dircolors-solarized"]
    path = bash/plugins/dircolors-solarized
    url = https://github.com/seebi/dircolors-solarized.git
    update = merge # <-- this is what you need to add

Or configure it in command line,

# replace $name with a real submodule name
git config -f .gitmodules submodule.$name.update merge

Since the value of $var is the empty string, this:

if [ $var == $var1 ]; then

expands to this:

if [ == abcd ]; then

which is a syntax error.

You need to quote the arguments:

if [ "$var" == "$var1" ]; then

You can also use = rather than ==; that's the original syntax, and it's a bit more portable.

If you're using bash, you can use the [[ syntax, which doesn't require the quotes:

if [[ $var = $var1 ]]; then

Even then, it doesn't hurt to quote the variable reference, and adding quotes:

if [[ "$var" = "$var1" ]]; then

might save a future reader a moment trying to remember whether [[ ... ]] requires them.

Another simple example.

For this sample we can use 100x100 DIV-box:

<div id="box" style="width: 100px; height: 100px; border: solid 1px red;">
 // Red box contents here...
</div>

And small jQuery trick:

<script type="text/javascript">
  jQuery("#box").bind("resize", function() {
    alert("Box was resized from 100x100 to 200x200");
  });
  jQuery("#box").width(200).height(200).trigger("resize");
</script>

Steps:

1. We created DIV block element for resizing operatios
2. Add simple JavaScript code with:
   • jQuery bind
   • jQuery resizer with trigger action "resize" - trigger is most important thing in my example
3. After resize you can check the browser alert information

That's all. ;-)

I was trying to test an extjs application and after sucessfully setting a testingAuthenticationToken this suddenly stopped working with no obvious cause.

I couldn't get the above answers to work so my solution was to skip out this bit of spring in the test environment. I introduced a seam around spring like this:

public class SpringUserAccessor implements UserAccessor
{
    @Override
    public User getUser()
    {
        SecurityContext context = SecurityContextHolder.getContext();
        Authentication authentication = context.getAuthentication();
        return (User) authentication.getPrincipal();
    }
}

User is a custom type here.

I'm then wrapping it in a class which just has an option for the test code to switch spring out.

public class CurrentUserAccessor
{
    private static UserAccessor _accessor;

    public CurrentUserAccessor()
    {
        _accessor = new SpringUserAccessor();
    }

    public User getUser()
    {
        return _accessor.getUser();
    }

    public static void UseTestingAccessor(User user)
    {
        _accessor = new TestUserAccessor(user);
    }
}

The test version just looks like this:

public class TestUserAccessor implements UserAccessor
{
    private static User _user;

    public TestUserAccessor(User user)
    {
        _user = user;
    }

    @Override
    public User getUser()
    {
        return _user;
    }
}

In the calling code I'm still using a proper user loaded from the database:

    User user = (User) _userService.loadUserByUsername(username);
    CurrentUserAccessor.UseTestingAccessor(user);

Obviously this wont be suitable if you actually need to use the security but I'm running with a no-security setup for the testing deployment. I thought someone else might run into a similar situation. This is a pattern I've used for mocking out static dependencies before. The other alternative is you can maintain the staticness of the wrapper class but I prefer this one as the dependencies of the code are more explicit since you have to pass CurrentUserAccessor into classes where it is required.

Use a single backspace after each character printf("hello wor\bl\bd\n");

Most likely there is an error somewhere in the get_profile() call. In your view, before you return the request object, put this line:

request.user.get_profile()

It should raise the error, and give you a more detailed traceback, which you can then use to further debug.

If you just want go get to work real fast, and move along with your work...

Just export GIT_TERMINAL_PROMPT=1

$ export GIT_TERMINAL_PROMPT=1
$ go get [whatever]

It will now prompt you for a user/pass for the rest of your shell session. Put this in your .profile or setup git as above for a more permanent solution.

Ok this helped a lot, I couldn't find a fix.

Simply, I already port forwarded the FTP port to my server. (The default is 14147, I'll use this as example)

Go to Edit > General settings, Listening port should be the one your using, in this case 14147.

Then go to Passive Mode Settings, I checked "Use Custom Port", and entered in the Range 50000 - 50100.

Then on your router, port forward 50000 - 50100 to the server IP locally.

IPv4 specific settings I left at default, reconnected my client, and bam now the file listing appears.

Ensure your servers firewall has an inbound rule set to accept 14147, and 50000-50100.

Basically what Evan stated. I can't attest to the security of opening these ports, but this is what finally got my Filezilla client and server to communicate and view files. Hope this helps someone.

All of the answers didn't work for me, I checked the playlist URL and seen that playlist parameter changed to list! So it should be:

&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs

So here is the full code I use make a clean, looping, autoplay video:

<iframe width="100%" height="425" src="https://www.youtube.com/embed/MavEpJETfgI?autoplay=1&showinfo=0&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs&rel=0" frameborder="0" allowfullscreen></iframe>

I would suggest you to use CryptoJS in this case.

Basically CryptoJS is a growing collection of standard and secure cryptographic algorithms implemented in JavaScript using best practices and patterns. They are fast, and they have a consistent and simple interface.

So In case you want calculate hash(MD5) of your password string then do as follows :

<script src="http://crypto-js.googlecode.com/svn/tags/3.0.2/build/rollups/md5.js"></script>
<script>
    var passhash = CryptoJS.MD5(password).toString();

    $.post(
      'includes/login.php', 
      { user: username, pass: passhash },
      onLogin, 
      'json' );
</script>

So this script will post hash of your password string to the server.

For further info and support on other hash calculating algorithms you can visit at:

http://code.google.com/p/crypto-js/

JavaScript doesn't have associate arrays. You need to use Objects instead:

var obj = {};
var name = "name";
var val = 2;
obj[name] = val;
console.log(obj);?

To get value you can use now different ways:

console.log(obj.name);?
console.log(obj[name]);?
console.log(obj["name"]);?

Scenario / Solution 1:
Ensure your Folder / Sub-folder is not in the .gitignore file, by any chance.

Scenario / Solution 2:
By default, git add . works recursively.

Scenario / Solution 3:
git add --all :/ works smoothly, where git add . doesn't (work).
(@JasonHartley's comment)

Scenario / Solution 4:
The issue I personally faced was adding Subfolders or Files, which were common between multiple Folders.

For example:
Folder/Subfolder-L1/Subfolder-L2/...file12.txt
Folder/Subfolder-L1/Subfolder-L2/Subfolder-L3/...file123.txt
Folder/Subfolder-L1/...file1.txt

So Git was recommending me to add git submodule, which I tried but was a pain.

Finally what worked for me was:

1. git add one file that's at the last end / level of a Folder.
For example:
git add Folder/Subfolder-L1/Subfolder-L2/Subfolder-L3/...file123.txt

2. git add --all :/ now.
It'll very swiftly add all the Folders, Subfolders and files.

With bootstrap you can use

<a href="#/new-page.html" class="btn btn-primary">
    Click
</a>

If anyone wants to debug and release separate build variant using Android Studio 3.5, follow the below steps: 1. Set build variant to release mode.

2. Go to File >> Project Structure
3. Select Modules, then Signing Config
4. Click in the Plus icon under Signing Config

5. Select release section and Provide your release App Information then Apply and OK.

6. Go to your app level build.gradle and change your buildTypes > "release" section like below Screenshot.

Then Run your Project. Happy Coding.

canvas.onmousedown = function(e) {
    pos_left = e.pageX - e.currentTarget.offsetLeft;
    pos_top = e.pageY - e.currentTarget.offsetTop;
    console.log(pos_left, pos_top)
}

HTMLElement.offsetLeft

The HTMLElement.offsetLeft read-only property returns the number of pixels that the upper left corner of the current element is offset to the left within the HTMLElement.offsetParent node.

For block-level elements, offsetTop, offsetLeft, offsetWidth, and offsetHeight describe the border box of an element relative to the offsetParent.

However, for inline-level elements (such as span) that can wrap from one line to the next, offsetTop and offsetLeft describe the positions of the first border box (use Element.getClientRects() to get its width and height), while offsetWidth and offsetHeight describe the dimensions of the bounding border box (use Element.getBoundingClientRect() to get its position). Therefore, a box with the left, top, width and height of offsetLeft, offsetTop, offsetWidth and offsetHeight will not be a bounding box for a span with wrapped text.

HTMLElement.offsetTop

The HTMLElement.offsetTop read-only property returns the distance of the current element relative to the top of the offsetParent node.

MouseEvent.pageX

The pageX read-only property returns the X (horizontal) coordinate in pixels of the event relative to the whole document. This property takes into account any horizontal scrolling of the page.

MouseEvent.pageY

The MouseEvent.pageY read-only property returns the Y (vertical) coordinate in pixels of the event relative to the whole document. This property takes into account any vertical scrolling of the page.

I had to use pip3 instead of pip in order to get the right versions for the right version of python (python 3.4 instead of python 2.x)

Check what you got install at: /usr/local/lib/python3.4/dist-packages

Also, when you run python, you might have to write python3.4 instead of python in order to use the right version of python.

This solved my problem in version 3.5.2.

$remote.empty().append(new Option()).trigger('change');

According to this issue you need an empty option inside select tag for the placeholder to show up.

DriveInfo will help you with some of those (but it doesn't work with UNC paths), but really I think you will need to use GetDiskFreeSpaceEx. You can probably achieve some functionality with WMI. GetDiskFreeSpaceEx looks like your best bet.

Chances are you will probably have to clean up your paths to get it to work properly.

JavaScript's 'strict not equal' operator (!==) on comparison with undefined does not result in false on null values.

var createTouch = null;
isTouch = createTouch !== undefined  // true

To achieve an equivalent behaviour in PHP, you can check whether the variable name exists in the keys of the result of get_defined_vars().

// just to simplify output format
const BR = '<br>' . PHP_EOL;

// set a global variable to test independence in local scope
$test = 1;

// test in local scope (what is working in global scope as well)
function test()
{
  // is global variable found?
  echo '$test ' . ( array_key_exists('test', get_defined_vars())
                    ? 'exists.' : 'does not exist.' ) . BR;
  // $test does not exist.

  // is local variable found?
  $test = null;
  echo '$test ' . ( array_key_exists('test', get_defined_vars())
                    ? 'exists.' : 'does not exist.' ) . BR;
  // $test exists.

  // try same non-null variable value as globally defined as well
  $test = 1;
  echo '$test ' . ( array_key_exists('test', get_defined_vars())
                    ? 'exists.' : 'does not exist.' ) . BR;
  // $test exists.

  // repeat test after variable is unset
  unset($test);
  echo '$test ' . ( array_key_exists('test', get_defined_vars())
                    ? 'exists.' : 'does not exist.') . BR;
  // $test does not exist.
}

test();

In most cases, isset($variable) is appropriate. That is aquivalent to array_key_exists('variable', get_defined_vars()) && null !== $variable. If you just use null !== $variable without prechecking for existence, you will mess up your logs with warnings because that is an attempt to read the value of an undefined variable.

However, you can apply an undefined variable to a reference without any warning:

// write our own isset() function
function my_isset(&$var)
{
  // here $var is defined
  // and initialized to null if the given argument was not defined
  return null === $var;
}

// passing an undefined variable by reference does not log any warning
$is_set = my_isset($undefined_variable);   // $is_set is false

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

This is an old thread but just in case anyone comes across it like I did. pi.FileName needs to be set to the file name (and possibly full path to file ) of the executable you want to use to open your file. The below code works for me to open a video file with VLC.

var path = files[currentIndex].fileName;
var pi = new ProcessStartInfo(path)
{
    Arguments = Path.GetFileName(path),
    UseShellExecute = true,
    WorkingDirectory = Path.GetDirectoryName(path),
    FileName = "C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe",
    Verb = "OPEN"
};
Process.Start(pi)

Tigran's answer works but will use windows' default application to open your file, so using ProcessStartInfo may be useful if you want to open the file with an application that is not the default.

Have a look at this list on Wikipedia about which browsers support SVG. It also provides links to more details in the footnotes. Firefox for example supports basic SVG, but at the moment lacks most animation features.

A tutorial about how to create SVG objects using Javascript can be found here:

var svgns = "http://www.w3.org/2000/svg";
var svgDocument = evt.target.ownerDocument;
var shape = svgDocument.createElementNS(svgns, "circle");
shape.setAttributeNS(null, "cx", 25);
shape.setAttributeNS(null, "cy", 25);
shape.setAttributeNS(null, "r",  20);
shape.setAttributeNS(null, "fill", "green"); 

Dim sHostName As String

sHostName = Environ$("computername")

Try this :

public String ConvertMessage(String content_sendout){

        //use unicode (004E00650077) need to change to hex (&#x004E&#x;0065&#x;0077;) first ;
        String resultcontent_sendout = "";
        int i = 4;
        int lengthwelcomemsg = content_sendout.length()/i;
        for(int nadd=0;nadd<lengthwelcomemsg;nadd++){
            if(nadd == 0){
                resultcontent_sendout = "&#x"+content_sendout.substring(nadd*i, (nadd*i)+i) + ";&#x";
            }else if(nadd == lengthwelcomemsg-1){
                resultcontent_sendout += content_sendout.substring(nadd*i, (nadd*i)+i) + ";";
            }else{
                resultcontent_sendout += content_sendout.substring(nadd*i, (nadd*i)+i) + ";&#x";
            }
        }
        return resultcontent_sendout;
    }

Well, since liquibase is open source there's always the source code which you could check.

Some of the data type classes seem to have a method toDatabaseDataType() which should give you information about what type works (is used) on a specific data base.

I know that I am late but, I happen to see this and I have a suggestion.. For those looking for cross-browser support, I wouldn't recommend class toggling via JS. It may be a little more work but it is more supported through all browsers.

A very simple solution to Q2 which I'm surprised nobody answered already. Use the method from Q1 to find the sum of the two missing numbers. Let's denote it by S, then one of the missing numbers is smaller than S/2 and the other is bigger than S/2 (duh). Sum all the numbers from 1 to S/2 and compare it to the formula's result (similarly to the method in Q1) to find the lower between the missing numbers. Subtract it from S to find the bigger missing number.

Mysql has this handy UPDATE INTO command ;)

edit Looks like they renamed it to REPLACE

REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted

you can also use: s.lower() in str.lower()

I don't think anyone has explained here that one issue is that you need "member pointers" rather than normal function pointers.

Member pointers to functions are not simply function pointers. In implementation terms, the compiler cannot use a simple function address because, in general, you don't know the address to call until you know which object to dereference for (think virtual functions). You also need to know the object in order to provide the this implicit parameter, of course.

Having said that you need them, now I'll say that you really need to avoid them. Seriously, member pointers are a pain. It is much more sane to look at object-oriented design patterns that achieve the same goal, or to use a boost::function or whatever as mentioned above - assuming you get to make that choice, that is.

If you are supplying that function pointer to existing code, so you really need a simple function pointer, you should write a function as a static member of the class. A static member function doesn't understand this, so you'll need to pass the object in as an explicit parameter. There was once a not-that-unusual idiom along these lines for working with old C code that needs function pointers

class myclass
{
  public:
    virtual void myrealmethod () = 0;

    static void myfunction (myclass *p);
}

void myclass::myfunction (myclass *p)
{
  p->myrealmethod ();
}

Since myfunction is really just a normal function (scope issues aside), a function pointer can be found in the normal C way.

EDIT - this kind of method is called a "class method" or a "static member function". The main difference from a non-member function is that, if you reference it from outside the class, you must specify the scope using the :: scope resolution operator. For example, to get the function pointer, use &myclass::myfunction and to call it use myclass::myfunction (arg);.

This kind of thing is fairly common when using the old Win32 APIs, which were originally designed for C rather than C++. Of course in that case, the parameter is normally LPARAM or similar rather than a pointer, and some casting is needed.

I had a button where the background-image had a shadow below it so the text alignment was off from the top. Changing the line-height wouldn't help. I added padding-bottom to it and it worked.

So what you have to do is determine the line-height you want to play with. So, for example, if I have a button who's height is truly 90px but I want the line-height to be 80px I would have something like this:

input[type=butotn].mybutton{
    background: url(my/image.png) no-repeat center top; /*Image is 90px x 150px*/
    width: 150px;
    height: 80px; /*shadow at the bottom is 10px (90px-10px)*/
    padding-bottom: 10px; /*the padding will make up for the lost height while maintaining the line-height to the proper height */

}

I hope this helps.

We can create such type of array to use this last value will be updated into column or key value and we will get unique value from the array...

$array = array (1,3,4,2,1,7,4,9,7,5,9);
    $data=array();
    foreach($array as $value ){

        $data[$value]= $value;

    }

    array_keys($data);
    OR
    array_values($data);

Users codelogic and harley are correct, but keep in mind if you know the string is an integer (for example, 545) you can call int("545") without first casting to float.

If your strings are in a list, you could use the map function as well.

>>> x = ["545.0", "545.6", "999.2"]
>>> map(float, x)
[545.0, 545.60000000000002, 999.20000000000005]
>>>

It is only good if they're all the same type.

Like this... I used it to read Chinese characters...

Dim reader as StreamReader = My.Computer.FileSystem.OpenTextFileReader(filetoimport.Text)
Dim a as String

Do
   a = reader.ReadLine
   '
   ' Code here
   '
Loop Until a Is Nothing

reader.Close()

You mention that you want to avoid adding the directory to search path if it already exists there. Is your intention to store the directory permanently to the path, or just temporarily for batch file's sake?

If you wish to add (or remove) directories permanently to PATH, take a look at Path Manager (pathman.exe) utility in Windows Resource Kit Tools for administrative tasks, http://support.microsoft.com/kb/927229. With that you can add or remove components of both system and user paths, and it will handle anomalies such as duplicate entries.

If you need to modify the path only temporarily for a batch file, I would just add the extra path in front of the path, with the risk of slight performance hit because of duplicate entry in the path.

Another point to mention is that you should ensure that your equality function is as you expect. You should override the equals method to set up what properties of your object have to match for two instances to be considered equal.

Then you can just do mylist.contains(item)

This is an old question, but since it still comes up at the top of my results in Google, here's another way.

import pandas as pd
import numpy as np

df = pd.DataFrame({'col1':list("abc"),'col2':range(3)},index = range(3))

Say you want to replicate the rows where col1="b".

reps = [3 if val=="b" else 1 for val in df.col1]
df.loc[np.repeat(df.index.values, reps)]

You could replace the 3 if val=="b" else 1 in the list interpretation with another function that could return 3 if val=="b" or 4 if val=="c" and so on, so it's pretty flexible.

You must add this code in your Service class so that it handles the case when your process is being killed

 @Override
    public void onTaskRemoved(Intent rootIntent) {
        Intent restartServiceIntent = new Intent(getApplicationContext(), this.getClass());
        restartServiceIntent.setPackage(getPackageName());

        PendingIntent restartServicePendingIntent = PendingIntent.getService(getApplicationContext(), 1, restartServiceIntent, PendingIntent.FLAG_ONE_SHOT);
        AlarmManager alarmService = (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
        alarmService.set(
                AlarmManager.ELAPSED_REALTIME,
                SystemClock.elapsedRealtime() + 1000,
                restartServicePendingIntent);

        super.onTaskRemoved(rootIntent);
    }

One important thing for passing multidimensional arrays is:

• First array dimension need not be specified.
• Second(any any further)dimension must be specified.

1.When only second dimension is available globally (either as a macro or as a global constant)

const int N = 3;

void print(int arr[][N], int m)
{
int i, j;
for (i = 0; i < m; i++)
  for (j = 0; j < N; j++)
    printf("%d ", arr[i][j]);
}

int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
print(arr, 3);
return 0;
}

2.Using a single pointer: In this method,we must typecast the 2D array when passing to function.

void print(int *arr, int m, int n)
{
int i, j;
for (i = 0; i < m; i++)
  for (j = 0; j < n; j++)
    printf("%d ", *((arr+i*n) + j));
 }

int main()
{
int arr[][3] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}};
int m = 3, n = 3;

// We can also use "print(&arr[0][0], m, n);"
print((int *)arr, m, n);
return 0;
}

To delete null and also empty entries Try this

  foreach (var column in drEntitity.Columns.Cast<DataColumn>().ToArray())
            {
                if (drEntitity.AsEnumerable().All(dr => dr.IsNull(column) | string.IsNullOrEmpty( dr[column].ToString())))
                    drEntitity.Columns.Remove(column);
            }

Once you generated the file, and changed your password, you can run as below,

cntlm -H

Username will be the same. it will ask for password, give it, then copy the PassNTLMv2, edit the cntlm.ini, then just run the following

cntlm -v

Here is the solution that worked for me:

1. Open Visual Studio command prompt tool (as an administrator). On windows 10 it might be called 'Developer command prompt'.
2. Navigate to where you have the CMake executable
3. Run Cmake.exe
4. Proceed as usual to select build and source folder
5. Select the appropriate Visual Studio compiler and hit the configure button

Hopefully it should run without problems.

"Best" helpdesk system is very subjective, of course, but I recommend Request Tracker (aka RT).

It has a default workflow built in, but is easily configured for alternate workflows using the "Scrips" and templates. Very extensible if you want.

public void keyPressed(KeyEvent e) {
    if (e.getKeyCode() == KeyEvent.VK_RIGHT ) {
            //Right arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_LEFT ) {
            //Left arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_UP ) {
            //Up arrow key code
    } else if (e.getKeyCode() == KeyEvent.VK_DOWN ) {
            //Down arrow key code
    }

    repaint();
}

The KeyEvent codes are all a part of the API: http://docs.oracle.com/javase/7/docs/api/java/awt/event/KeyEvent.html

If you have a list of lists (tracked_output_sheet in my case), where you want to delete last element from each list, you can use the following code:

interim = []
for x in tracked_output_sheet:interim.append(x[:-1])
tracked_output_sheet= interim

Here is a heavy tutorial that has good stuff in it to pick out:

Although optimally it would be nice if your code can run parallel, it can be the case you're simply using a thread so you do not block the UI thread, even if your app's usage flow will have to wait for it.

You've got pretty much 2 options here;

1. You can execute the code you want waiting, in the AsyncTask itself. If it has to do with updating the UI(thread), you can use the onPostExecute method. This gets called automatically when your background work is done.

2. If you for some reason are forced to do it in the Activity/Fragment/Whatever, you can also just make yourself a custom listener, which you broadcast from your AsyncTask. By using this, you can have a callback method in your Activity/Fragment/Whatever which only gets called when you want it: aka when your AsyncTask is done with whatever you had to wait for.

Specifying a flex attribute to the container worked for me:

.container {
    flex: 0 0 auto;
}

This ensures the height is set and doesn't grow either.

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

I agree with Ken's answer as being the most dynamic and I like to take it a step further. If it's a function that you call multiple times with different arguments - I use Ken's design but then add default values:

function load(context) {

    var defaults = {
        parameter1: defaultValue1,
        parameter2: defaultValue2,
        ...
    };

    var context = extend(defaults, context);

    // do stuff
}

This way, if you have many parameters but don't necessarily need to set them with each call to the function, you can simply specify the non-defaults. For the extend method, you can use jQuery's extend method ($.extend()), craft your own or use the following:

function extend() {
    for (var i = 1; i < arguments.length; i++)
        for (var key in arguments[i])
            if (arguments[i].hasOwnProperty(key))
                arguments[0][key] = arguments[i][key];
    return arguments[0];
}

This will merge the context object with the defaults and fill in any undefined values in your object with the defaults.

Another option using labs and setting colour to NULL.

ggplot(df, aes(x, y, colour = g)) +
  geom_line(stat = "identity") +
  theme(legend.position = "bottom") +
  labs(colour = NULL)

On CentOS 5.x, a simple yum update openssl updated the openssl package which updated the system ca-bundle.crt file and fixed the problem for me.

The same may be true for other distributions.

To find a very long list of words in big files, it can be more efficient to use egrep:

$ tr '\n' '|' < A > A_regex
$ egrep -f A_regex B

You have to load the db library first. In autoload.php add :

$autoload['libraries'] = array('database');

Also, try renaming User model class for "User_model".

I'd like to centralize the creation of the error response in this way:

app.get('/test', function(req, res){
  throw {status: 500, message: 'detailed message'};
});

app.use(function (err, req, res, next) {
  res.status(err.status || 500).json({status: err.status, message: err.message})
});

So I have always the same error output format.

PS: of course you could create an object to extend the standard error like this:

const AppError = require('./lib/app-error');
app.get('/test', function(req, res){
  throw new AppError('Detail Message', 500)
});

'use strict';

module.exports = function AppError(message, httpStatus) {
  Error.captureStackTrace(this, this.constructor);
  this.name = this.constructor.name;
  this.message = message;
  this.status = httpStatus;
};

require('util').inherits(module.exports, Error);

If your using Office 2016 or later, or Office 365, there is a new function that acts similarly to a CASE function called IFS. Here's the description of the function from Microsoft's documentation:

The IFS function checks whether one or more conditions are met, and returns a value that corresponds to the first TRUE condition. IFS can take the place of multiple nested IF statements, and is much easier to read with multiple conditions.

An example of usage follows:

=IFS(A2>89,"A",A2>79,"B",A2>69,"C",A2>59,"D",TRUE,"F")

You can even specify a default result:

To specify a default result, enter TRUE for your final logical_test argument. If none of the other conditions are met, the corresponding value will be returned.

The default result feature is included in the example shown above.

You can read more about it on Microsoft's Support Documentation

The JVM will start with memory useage at the initial heap level. If the maxheap is higher, it will grow to the maxheap size as memory requirements exceed it's current memory.

So,

• -Xms512m -Xmx512m

JVM starts with 512 M, never resizes.

• -Xms64m -Xmx512m

JVM starts with 64M, grows (up to max ceiling of 512) if mem. requirements exceed 64.

Example of how to use it :

// a 5x5 array, with at most 10 elements "bufferized" -> the last 10 elements will not be taken by GC process
Array2DWeakRefsBuffered<Image> myArray = new Array2DWeakRefsBuffered<Image>(5,5,10);
Image img = myArray.set(anImage,0,0);
if(myArray.exists(3,3))
{
    System.out.println("Image at 3,3 is still in memory");
}

A char variable is actually an 8-bit integral value. It will have values from 0 to 255. These are ASCII codes. 0 stands for the C-null character, and 255 stands for an empty symbol.

So, when you write the following assignment:

char a = 'a'; 

It is the same thing as:

char a = 97;

So, you can compare two char variables using the >, <, ==, <=, >= operators:

char a = 'a';
char b = 'b';

if( a < b ) printf("%c is smaller than %c", a, b);
if( a > b ) printf("%c is smaller than %c", a, b);
if( a == b ) printf("%c is equal to %c", a, b);

It means you should use logging framework like logback or log4j and instead of printing exceptions directly:

e.printStackTrace();

you should log them using this frameworks' API:

log.error("Ops!", e);

Logging frameworks give you a lot of flexibility, e.g. you can choose whether you want to log to console or file - or maybe skip some messages if you find them no longer relevant in some environment.

if self.table:
    print 'It is not empty'

The different is .html() evaluate as a html, .text() avaluate as a text.
Consider a block of html
HTML

<div id="mydiv">
<div class="mydiv">
    This is a div container
    <ul>
      <li><a href="#">Link 1</a></li>
      <li><a href="#">Link 2</a></li>
    </ul>
    a text after ul
</div>
</div>

JS

var out1 = $('#mydiv').html();
var out2 = $('#mydiv').text();
console.log(out1) // This output all the html tag
console.log(out2) // This is output just the text 'This is a div container Link 1 Link 2 a text after ul'

The illustration is from this link http://api.jquery.com/text/

And as an addendum to all answers, FYI: override is not a keyword, but a special kind of identifier! It has meaning only in the context of declaring/defining virtual functions, in other contexts it's just an ordinary identifier. For details read 2.11.2 of The Standard.

#include <iostream>

struct base
{
    virtual void foo() = 0;
};

struct derived : base
{
    virtual void foo() override
    {
        std::cout << __PRETTY_FUNCTION__ << std::endl;
    }
};

int main()
{
    base* override = new derived();
    override->foo();
    return 0;
}

Output:

zaufi@gentop /work/tests $ g++ -std=c++11 -o override-test override-test.cc
zaufi@gentop /work/tests $ ./override-test
virtual void derived::foo()

Nope, BeautifulSoup, by itself, does not support XPath expressions.

An alternative library, lxml, does support XPath 1.0. It has a BeautifulSoup compatible mode where it'll try and parse broken HTML the way Soup does. However, the default lxml HTML parser does just as good a job of parsing broken HTML, and I believe is faster.

Once you've parsed your document into an lxml tree, you can use the .xpath() method to search for elements.

try:
    # Python 2
    from urllib2 import urlopen
except ImportError:
    from urllib.request import urlopen
from lxml import etree

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = urlopen(url)
htmlparser = etree.HTMLParser()
tree = etree.parse(response, htmlparser)
tree.xpath(xpathselector)

There is also a dedicated lxml.html() module with additional functionality.

Note that in the above example I passed the response object directly to lxml, as having the parser read directly from the stream is more efficient than reading the response into a large string first. To do the same with the requests library, you want to set stream=True and pass in the response.raw object after enabling transparent transport decompression:

import lxml.html
import requests

url =  "http://www.example.com/servlet/av/ResultTemplate=AVResult.html"
response = requests.get(url, stream=True)
response.raw.decode_content = True
tree = lxml.html.parse(response.raw)

Of possible interest to you is the CSS Selector support; the CSSSelector class translates CSS statements into XPath expressions, making your search for td.empformbody that much easier:

from lxml.cssselect import CSSSelector

td_empformbody = CSSSelector('td.empformbody')
for elem in td_empformbody(tree):
    # Do something with these table cells.

Coming full circle: BeautifulSoup itself does have very complete CSS selector support:

for cell in soup.select('table#foobar td.empformbody'):
    # Do something with these table cells.

Try man exit.

Oh, and:

#include <stdlib.h>

int main(void) {
  /*  ...  */
  if (error_occured) {
    return (EXIT_FAILURE);
  }
  /*  ...  */
  return (EXIT_SUCCESS);
}

I was able to fix this problem by setting font-size: 0 .

I have a partial answer for you. This is based on what I get from GCC:

__DATE__ gives something like "Jul 27 2012"

__TIME__ gives something like 21:06:19

Put this text in an include file called build_defs.h:

#ifndef BUILD_DEFS_H

#define BUILD_DEFS_H


#define BUILD_YEAR ((__DATE__[7] - '0') * 1000 +  (__DATE__[8] - '0') * 100 + (__DATE__[9] - '0') * 10 + __DATE__[10] - '0')

#define BUILD_DATE ((__DATE__[4] - '0') * 10 + __DATE__[5] - '0')


#if 0
#if (__DATE__[0] == 'J' && __DATE__[1] == 'a' && __DATE__[2] == 'n')
    #define BUILD_MONTH  1
#elif (__DATE__[0] == 'F' && __DATE__[1] == 'e' && __DATE__[2] == 'b')
    #define BUILD_MONTH  2
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'r')
    #define BUILD_MONTH  3
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'p' && __DATE__[2] == 'r')
    #define BUILD_MONTH  4
#elif (__DATE__[0] == 'M' && __DATE__[1] == 'a' && __DATE__[2] == 'y')
    #define BUILD_MONTH  5
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'n')
    #define BUILD_MONTH  6
#elif (__DATE__[0] == 'J' && __DATE__[1] == 'u' && __DATE__[2] == 'l')
    #define BUILD_MONTH  7
#elif (__DATE__[0] == 'A' && __DATE__[1] == 'u' && __DATE__[2] == 'g')
    #define BUILD_MONTH  8
#elif (__DATE__[0] == 'S' && __DATE__[1] == 'e' && __DATE__[2] == 'p')
    #define BUILD_MONTH  9
#elif (__DATE__[0] == 'O' && __DATE__[1] == 'c' && __DATE__[2] == 't')
    #define BUILD_MONTH 10
#elif (__DATE__[0] == 'N' && __DATE__[1] == 'o' && __DATE__[2] == 'v')
    #define BUILD_MONTH 11
#elif (__DATE__[0] == 'D' && __DATE__[1] == 'e' && __DATE__[2] == 'c')
    #define BUILD_MONTH 12
#else
    #error "Could not figure out month"
#endif
#endif

#define BUILD_HOUR ((__TIME__[0] - '0') * 10 + __TIME__[1] - '0')
#define BUILD_MIN ((__TIME__[3] - '0') * 10 + __TIME__[4] - '0')
#define BUILD_SEC ((__TIME__[6] - '0') * 10 + __TIME__[7] - '0')

#endif // BUILD_DEFS_H

I tested the above with GCC on Linux. It all works great, except for the problem that I can't figure out how to get a number for the month. If you check the section that is under #if 0 you will see my attempt to figure out the month. GCC complains with this message:

error: token ""Jul 27 2012"" is not valid in preprocessor expressions

It would be trivial to convert the three-letter month abbreviation into some sort of unique number; just subtract 'A' from the first letter and 'a' from the second and the third, and then convert to a base-26 number or something. But I want to make it evaluate to 1 for January and so on, and I can't figure out how to do that.

EDIT: I just realized that you asked for strings, not expressions that evaluate to integer values.

I tried to use these tricks to build a static string:

#define BUILD_MAJOR 1
#define BUILD_MINOR 4
#define VERSION STRINGIZE(BUILD_MAJOR) "." STRINGIZE(BUILD_MINOR)

char build_str[] = {
    BUILD_MAJOR + '0', '.' BUILD_MINOR + '0', '.',
    __DATE__[7], __DATE__[8], __DATE__[9], __DATE__[10],
    '\0'
};

GCC complains that "initializer element is not constant" for __DATE__.

Sorry, I'm not sure how to help you. Maybe you can try this stuff with your compiler? Or maybe it will give you an idea.

Good luck.

P.S. If you don't need things to be numbers, and you just want a unique build string, it's easy:

const char *build_str = "Version: " VERSION " " __DATE__ " " __TIME__;

With GCC, this results in something like:

Version: 1.4 Jul 27 2012 21:53:59

You can bridge from String to NSString and convert from CInt to Int like this:

var myint: Int = Int(stringNumb.bridgeToObjectiveC().intValue)

For React users,

Just replace 10 with your max length requirement

 <input type="number" onInput={(e) => e.target.value = e.target.value.slice(0, 10)}/>

In the case you need to force the reinstallation of pip itself you can do:

python -m pip install --upgrade --force-reinstall pip

Try this one

<input type="text" onkeyup="trackChange(this.value)" id="myInput">
<script>
function trackChange(value) {
    window.open("http://www.google.com/search?output=search&q=" + value)
}
</script>

You can use this to print out the JVM defaults

import java.nio.charset.Charset;
import java.io.InputStreamReader;
import java.io.FileInputStream;

public class PrintCharSets {
        public static void main(String[] args) throws Exception {
                System.out.println("file.encoding=" + System.getProperty("file.encoding"));
                System.out.println("Charset.defaultCharset=" + Charset.defaultCharset());
                System.out.println("InputStreamReader.getEncoding=" + new InputStreamReader(new FileInputStream("./PrintCharSets.java")).getEncoding());
        }
}

Compile and Run

javac PrintCharSets.java && java PrintCharSets

Your code (vector1 == vector2) is correct C++ syntax. There is an == operator for vectors.

If you want to compare short vector with a portion of a longer vector, you can use theequal() operator for vectors. (documentation here)

Here's an example:

using namespace std;

if( equal(vector1.begin(), vector1.end(), vector2.begin()) )
    DoSomething();

You can always jump right to the root controller:

UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *vc = [storyboard instantiateInitialViewController];
vc.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self presentViewController:vc animated:YES completion:NULL];

datetime.replace() will provide the best options. Also, it provides facility for replacing day, year, and month.

Suppose we have a datetime object and date is represented as: "2017-05-04"

>>> from datetime import datetime
>>> date = datetime.strptime('2017-05-04',"%Y-%m-%d")
>>> print(date)
2017-05-04 00:00:00
>>> date = date.replace(minute=59, hour=23, second=59, year=2018, month=6, day=1)
>>> print(date)
2018-06-01 23:59:59

You are probably experiencing an issue with a firewall. The 'problem' is that the port you specify is not the only port used, it uses 1 or maybe even 2 more ports for RMI, and those are probably blocked by a firewall.

One of the extra ports will not be know up front if you use the default RMI configuration, so you have to open up a big range of ports - which might not amuse the server administrator.

There is a solution that does not require opening up a lot of ports however, I've gotten it to work using the combined source snippets and tips from

It's even possible to setup an ssh tunnel and still get it to work :-)

try this:

$('form').submit(function(){
    // this function will be raised when submit button is clicked.
    // perform submit operations here
});

If you want to pass global variables into new scripts, you can create a python file that is only meant for holding global variables (e.g. globals.py). When you import this file at the top of the child script, it should have access to all of those variables.

If you are writing to these variables, then that is a different story. That involves concurrency and locking the variables, which I'm not going to get into unless you want.

With the -atime, -ctime, and -mtime switches to find, you can get close to what you want to achieve.

Actually I cannot agree to each statement.

"COALESCE expects all arguments to be of same datatype."

This is wrong, see below. Arguments can be different data types, that is also documented: If all occurrences of expr are numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that data type, and returns that data type.. Actually this is even in contradiction to common expression "COALESCE stops at first occurrence of a non-Null value", otherwise test case No. 4 should not raise an error.

Also according to test case No. 5 COALESCE does an implicit conversion of arguments.

DECLARE
    int_val INTEGER := 1;
    string_val VARCHAR2(10) := 'foo';

    END;

    DBMS_OUTPUT.PUT_LINE( '5. COALESCE(SYSDATE,SYSTIMESTAMP) -> '|| COALESCE(SYSDATE,SYSTIMESTAMP) );

END;

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

Here is a benchmark of three different methods:

1. The implementation of the accepted answer from Kyle.
2. An approach based on random index selection with HashSet duplication filtering, from drzaus.
3. A more academic approach posted by Jesús López, called Fisher–Yates shuffle.

The testing will consist of benchmarking the performance with multiple different list sizes and selection sizes.

I also included a measurement of the standard deviation of these three methods, i.e. how well distributed the random selection appears to be.

In a nutshell, drzaus's simple solution seems to be the best overall, from these three. The selected answer is great and elegant, but it's not that efficient, given that the time complexity is based on the sample size, not the selection size. Consequently, if you select a small number of items from a long list, it will take orders of magnitude more time. Of course it still performs better than the solutions based on complete reordering.

Curiously enough, this O(n) time complexity issue is true even if you only touch the list when you actually return an item, like I do in my implementation. The only thing I can thing of is that Random.Next() is pretty slow, and that performance benefits if you generate only one random number for each selected item.

And, also interestingly, the StdDev of Kyle's solution was significantly higher comparatively. I have no clue why; maybe the fault is in my implementation.

Sorry for the long code and output that will commence now; but I hope it's somewhat illuminative. Also, if you spot any issues in the tests or implementations, let me know and I'll fix it.

Avoid SELECT * in your main query.

Avoid duplicate columns: the JOIN condition ensures One.One_Name and two.One_Name will be equal therefore you don't need to return both in the SELECT clause.

Avoid duplicate column names: rename One.ID and Two.ID using 'aliases'.

Add an ORDER BY clause using the column names ('alises' where applicable) from the SELECT clause.

Suggested re-write:

SELECT T1.ID AS One_ID, T1.One_Name, 
       T2.ID AS Two_ID, T2.Two_name
  FROM One AS T1
       INNER JOIN two AS T2
          ON T1.One_Name = T2.One_Name
 ORDER 
    BY One_ID;

you can specify fields like this:

The git.exe from Github for windows is located in a path like C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\bin\git.exe1 You have to replace <username> and <numbersandletters> to the actual situation on your system.

In Android Studio you can specify the path to the Git executable at File->Settings...->Version Control->Git->Path to Git executable. Here you have to include the actual executable name. As an example, in my case the actual path is: C:\Users\dennis\AppData\Local\GitHub\PortableGit_69703d1db91577f4c666e767a6ca5ec50a48d243\bin\git.exe

Edit: Last git update has put the git.exe file in cmd\ folder instead of bin\ . so now the actual path will be as suggested in the comment below by al3xAndr3w.

C:\Users\<username>\AppData\Local\GitHub\PortableGit_<numbersandletters>\cmd\git.exe

I have used html line break instead of "\n" . It worked fine.

pip is run from the command line, not the Python interpreter. It is a program that installs modules, so you can use them from Python. Once you have installed the module, then you can open the Python shell and do import selenium.

The Python shell is not a command line, it is an interactive interpreter. You type Python code into it, not commands.

In JavaScript, there are truthy and falsy expressions. If you want to check if the property is undefined or not, there is a straight way of using an if condition as given,

1. Using truthy/falsy concept.

if(!ob.someProp){
    console.log('someProp is falsy')
}

However, there are several more approaches to check the object has property or not, but it seems long to me. Here are those.

2. Using === undefined check in if condition

if(ob.someProp === undefined){
    console.log('someProp is undefined')
}

3. Using typeof

typeof acts as a combined check for the value undefined and for whether a variable exists.

if(typeof ob.someProp === 'undefined'){
    console.log('someProp is undefined')
}

4. Using hasOwnProperty method

The JavaScript object has built in the hasOwnProperty function in the object prototype.

if(!ob.hasOwnProperty('someProp')){
    console.log('someProp is undefined')
}

Not going in deep, but the 1^st way looks shortened and good to me. Here are the details on truthy/falsy values in JavaScript and undefined is the falsy value listed in there. So the if condition behaves normally without any glitch. Apart from the undefined, values NaN, false (Obviously), '' (empty string) and number 0 are also the falsy values.

Warning: Make sure the property value does not contain any falsy value, otherwise the if condition will return false. For such a case, you can use the hasOwnProperty method

Assuming you're fine with taking all of the changes in master, what you want is:

git checkout <my branch>

to switch the working tree to your branch; then:

git merge master

to merge all the changes in master with yours.

What works best for me is using quote() and eval() together.

For example, let's print each column using a for loop:

Columns <- names(dat)
for (i in 1:ncol(dat)){
  dat[, eval(quote(Columns[i]))] %>% print
}

This is the way I got it working for me:

  Tasks:
  - name: checking if the file 1 exists
     stat:      
      path: /path/to/foo abc.xts
     register: stat_result

  - name: moving file 1
    command: mv /path/to/foo abc.xts /tmp
    when: stat_result.stat.exists == True

the playbook above, will check if file abc.xts exists before move the file to tmp folder.

Is your problem to decide whether a particular number is prime? Then you need a primality test (easy). Or do you need all primes up to a given number? In that case prime sieves are good (easy, but require memory). Or do you need the prime factors of a number? This would require factorization (difficult for large numbers if you really want the most efficient methods). How large are the numbers you are looking at? 16 bits? 32 bits? bigger?

One clever and efficient way is to pre-compute tables of primes and keep them in a file using a bit-level encoding. The file is considered one long bit vector whereas bit n represents integer n. If n is prime, its bit is set to one and to zero otherwise. Lookup is very fast (you compute the byte offset and a bit mask) and does not require loading the file in memory.

A workaround for this I used was to include the data as a js file, that implements a function returning the raw data as a string:

html:

<!DOCTYPE html>
<html>

<head>
  <script src="script.js"></script>
  <script type="text/javascript">
    function loadData() {
      // getData() will return the string of data...
      document.getElementById('data').innerHTML = getData().replace('\n', '<br>');
    }
  </script>
</head>

<body onload='loadData()'>
  <h1>check out the data!</h1>
  <div id='data'></div>
</body>

</html>

script.js:

// function wrapper, just return the string of data (csv etc)
function getData () {
    return 'look at this line of data\n\
oh, look at this line'
}

See it in action here- http://plnkr.co/edit/EllyY7nsEjhLMIZ4clyv?p=preview The downside is you have to do some preprocessing on the file to support multilines (append each line in the string with '\n\').

val i = Intent(this, Page2::class.java)
            val getrec = list[position].promotion_id
            val bundle = Bundle()
            bundle.putString("stuff", getrec)
            i.putExtras(bundle)
            startActivity(i)

Page 2

        var bundle = getIntent().getExtras()
        var stuff = bundle.getString("stuff")

There is also:

info all-registers

Then you can get the register name you are interested in -- very useful for finding platform-specific registers (like NEON Q... on ARM).

You could use Linq's FirstOrDefault extension method:

string element = myList.FirstOrDefault(s => s.Contains(myString));

This will return the fist element that contains the substring myString, or null if no such element is found.

If all you need is the index, use the List<T> class's FindIndex method:

int index = myList.FindIndex(s => s.Contains(myString));

This will return the the index of fist element that contains the substring myString, or -1 if no such element is found.

I solved the problem as follows:

1. run MySQLInstanceConfig.exe

   C:\Program Files (x86)\MySQL\MySQL Server 5.1\bin\MySQLInstanceConfig.exe

2. Follow to the end without changing anything.

You can use a sort function :

var myarray=[25, 8, 7, 41]
myarray.sort( function(a,b) { return b - a; } );
// 7 8 25 41

Look at http://www.javascriptkit.com/javatutors/arraysort.shtml

input.name() needs to be inside a function; classes contain declarations, not random code.

I encourage you to use the -r flag for read which stands for:

-r  Do not treat a backslash character in any special way. Consider each
    backslash to be part of the input line.

I am citing from man 1 read.

Another thing is to take a filename as an argument.

Here is updated code:

#!/usr/bin/bash
filename="$1"
while read -r line; do
    name="$line"
    echo "Name read from file - $name"
done < "$filename"

According to Android Sqlite get last insert row id there is another query:

SELECT rowid from your_table_name order by ROWID DESC limit 1

NULL is a value that is valid for any pointer type. It represents the absence of a value.

A void pointer is a type. Any pointer type is convertible to a void pointer hence it can point to any value. This makes it good for general storage but bad for use. By itself it cannot be used to access a value. The program must have extra context to understand the type of value the void pointer refers to before it can access the value.

I believe sideshowbarker 's answer here has all the info you need to fix this. If your problem is just No 'Access-Control-Allow-Origin' header is present on the response you're getting, you can set up a CORS proxy to get around this. Way more info on it in the linked answer

You could also use:

request.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials; 

I think jQuery cannot find the element.

First of all find the element

var rowTemplate= document.getElementsByName("rowTemplate");

or

var rowTemplate = document.getElementById("rowTemplate"); 

or

var rowTemplate = $('#rowTemplate');

Then try your code again

rowTemplate.html().replace(....)

You can use the substring function:

let str = "12345.00";_x000D_
str = str.substring(0, str.length - 1);_x000D_
console.log(str);

This is the accepted answer, but as per the conversations below, the slice syntax is much clearer:

let str = "12345.00";_x000D_
str = str.slice(0, -1); _x000D_
console.log(str);

Another option:

UPDATE `table` SET the_col = current_timestamp

Looks odd, but works as expected. If I had to guess, I'd wager this is slightly faster than calling now().

Before you try searching for the elements within the iframe you will have to switch Selenium focus to the iframe.

Try this before searching for the elements within the iframe:

driver.switchTo().frame(driver.findElement(By.name("iFrameTitle")));

If a special character other than $, _, and # is used in the name of a column or table, the name must be enclosed in double quotations. Link

Well I'm not a pro in C++, but learnt it in school. I am using this algo for past 1 year to store different random values in a 1D array, but this will also work in 2D array after some changes. Any suggestions about the code are welcome.

In insert()

public void insert(String tableImg, Object object,
        ContentValues dataToInsert) {

   db.insert(tablename, null, dataToInsert);
}

Hope it helps you.

If you have an image imported as a resource in your project there is also this:

picPreview.Image = Properties.Resources.ImageName;

Where picPreview is the name of the picture box and ImageName is the name of the file you want to display.

*Resources are located by going to: Project --> Properties --> Resources

As an alternative source to the same problem, this answer cites using Maven 3 versus Maven 2 as the potential cause of this issue. Near as I can tell, this is due to changes in local repository resolution that was changed in Maven 3. Putting this here in case anyone else googles for it and reaches this answer (as I did).

There is no full-proof method to prevent your images being downloaded/stolen.

But, some solutions like: watermarking your images(from client side or server side), implement a background image, disable/prevent right clicks, slice images into small pieces and then present as a complete image to browser, you can also use flash to show images.

Personally, recommended methods are: Watermarking and flash. But it is a difficult and almost impossible mission to accomplish. As long as user is able to "see" that image, means they take "screenshot" to steal the image.

I think you can't. The SELECT element is rendered at a point beyond the reach of CSS and HTML. Is it grayed out?

But you can try to add a "size" atribute.

By sorting the file with sort first, you can then apply uniq.

It seems to sort the file just fine:

The DateTime.Now property returns the current date and time, for example 2011-07-01 10:09.45310.

The DateTime.Today property returns the current date with the time compnents set to zero, for example 2011-07-01 00:00.00000.

The DateTime.Today property actually is implemented to return DateTime.Now.Date:

public static DateTime Today {
  get {
    DateTime now = DateTime.Now;
    return now.Date;
  }
}

As far as I know, transitions currently work in Safari, Chrome, Firefox, Opera and Internet Explorer 10+.

This should produce a fade effect for you in these browsers:

a {_x000D_
    background-color: #FF0;_x000D_
}_x000D_
_x000D_
a:hover {_x000D_
    background-color: #AD310B;_x000D_
    -webkit-transition: background-color 1000ms linear;_x000D_
    -ms-transition: background-color 1000ms linear;_x000D_
    transition: background-color 1000ms linear;_x000D_
}

<a>Navigation Link</a>

Note: As pointed out by Gerald in the comments, if you put the transition on the a, instead of on a:hover it will fade back to the original color when your mouse moves away from the link.

This might come in handy, too: CSS Fundamentals: CSS 3 Transitions

The functional interfaces in Java don’t declare any checked or unchecked exception. We need to change the signature of the methods from:

boolean isActive() throws IOException; 
String getNumber() throwsIOException;

To:

boolean isActive();
String getNumber();

Or handle it with try-catch block:

public Set<String> getActiveAccountNumbers() {
  Stream<Account> s =  accounts.values().stream();
  s = s.filter(a -> 
    try{
      a.isActive();
    }catch(IOException e){
      throw new RuntimeException(e);
    }
  );
  Stream<String> ss = s.map(a -> 
    try{
      a.getNumber();
    }catch(IOException e){
      throw new RuntimeException(e);
    }
  );
  return ss.collect(Collectors.toSet());
}

Another option is to write a custom wrapper or use a library like ThrowingFunction. With the library we only need to add the dependency to our pom.xml:

<dependency>
    <groupId>pl.touk</groupId>
    <artifactId>throwing-function</artifactId>
    <version>1.3</version>
</dependency>

And use the specific classes like ThrowingFunction, ThrowingConsumer, ThrowingPredicate, ThrowingRunnable, ThrowingSupplier.

At the end the code looks like this:

public Set<String> getActiveAccountNumbers() {
  return accounts.values().stream()
    .filter(ThrowingPredicate.unchecked(Account::isActive))
    .map(ThrowingFunction.unchecked(Account::getNumber))
    .collect(Collectors.toSet());
}

There are some guys at Mozilla working on implementing a PDF reader using HTML5 and JavaScript. It is called pdf.js and one of the developers just made an interesting blog post about the project.

As per this article, it's not. The article also argues that it's not a good idea to make it one.

To quote from one of the comments:

So, I do not believe that CSS is turing complete. There is no capability to define a function in CSS. In order for a system to be turing-complete it has to be possible to write an interpreter: a function that interprets expressions that denote programs to execute. CSS has no variables that are directly accessible to the user; so you cannot even model the structure that represents the program to be interpreted in CSS.

Yes, it is possible, and has been implemented by popular usability testing website Silverback. If you look through the source code you can see that the background is made up of several images, placed on top of each other.

Here is the article demonstrating how to do the effect can be found on Vitamin. A similar concept for wrapping these 'onion skin' layers can be found on A List Apart.

Java has a large number of built-in exceptions for different scenarios.

In this case, you should throw an IllegalArgumentException, since the problem is that the caller passed a bad parameter.

There is a huge difference.

As most of the answers have already pointed out the theory, I would like to point out an easy example:

int x = 1;
//would print 1 as first statement will x = x and then x will increase
int x = x++;
System.out.println(x);

Now let's see ++x:

int x = 1;
//would print 2 as first statement will increment x and then x will be stored
int x = ++x;
System.out.println(x);

What you are trying to do can almost certainly be achieved with a set.

>>> x = set([1,2,3])
>>> x.add(2)
>>> x
set([1, 2, 3])
>>> x.add(4)
>>> x.add(4)
>>> x
set([1, 2, 3, 4])
>>> 

using a set's add method you can build your unique set of ids very quickly. Or if you already have a list

unique_ids = set(id_list)

as for getting your inputs in numeric form you can do something like

>>> ids = [int(n) for n in '350882 348521 350166\r\n'.split()]
>>> ids
[350882, 348521, 350166]

@Mark Cidade

Thanks Mark! This solved few days of research on wondering how should I call this from the PHP WshShell. So thanks to your code, I figured...

function __exec($tmppath, $cmd)
{
   $WshShell = new COM("WScript.Shell");
   $tmpf = rand(1000, 9999).".tmp"; // Temp file
   $tmpfp = $tmppath.'/'.$tmpf; // Full path to tmp file

   $oExec = $WshShell->Run("cmd /c $cmd -c ... > ".$tmpfp, 0, true);

   // return $oExec == 0 ? true : false; // Return True False after exec
   return $tmpf;
}

This is what worked for me in my case. Feel free to use and modify as per your needs. You can always add functionality within the function to automatically read the tmp file, assign it to a variable and/or return it and then delete the tmp file. Thanks again @Mark!

You should try slicing the image if possible into a smaller piece which could be repeated. I have sliced that image to a 101x101px image.

CSS:

body{
  background-image: url(SO_texture_bg.jpg);
  background-repeat:repeat;
}

But in some cases, we wouldn't be able to slice the image to a smaller one. In that case, I would use the whole image. But you could also use the CSS3 methods like what Mustafa Kamal had mentioned.

Wish you good luck.

auto is not a valid value for padding property, the only thing you can do is take out padding: 0; from the * declaration, else simply assign padding to respective property block.

If you remove padding: 0; from * {} than browser will apply default styles to your elements which will give you unexpected cross browser positioning offsets by few pixels, so it is better to assign padding: 0; using * and than if you want to override the padding, simply use another rule like

.container p {
   padding: 5px;
}

For the lazy guys:

First download cookie: http://plugins.jquery.com/cookie/

Add it to your html:

<script src="{% static 'designer/js/jquery.cookie.js' %}"></script>

Now you can create a working POST request:

var csrftoken = $.cookie('csrftoken');

function csrfSafeMethod(method) {
    // these HTTP methods do not require CSRF protection
    return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}

$.ajaxSetup({
    beforeSend: function(xhr, settings) {
        if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
            xhr.setRequestHeader("X-CSRFToken", csrftoken);
        }
    }
});

$.ajax(save_url, {
    type : 'POST',
    contentType : 'application/json',
    data : JSON.stringify(canvas),
    success: function () {
        alert("Saved!");
    }

})

It happens because Build Tools revision 24.4.1 doesn't exist.

The latest version is 23.0.2.
These tools is included in the SDK package and installed in the <sdk>/build-tools/ directory.

Don't confuse the Android SDK Tools with SDK Build Tools.

Change in your build.gradle

android {
   buildToolsVersion "23.0.2"
   // ...

}

If you are using the background image for the rounded corners then I would rather increase the padding style of the main div to give enough room for the rounded corners of the background image to be visible.

Try increasing the padding of the main div style:

#mainWrapperDivWithBGImage 
{   
    background: url("myImageWithRoundedCorners.jpg") no-repeat scroll 0 0 transparent;   
    height: 248px;   
    margin: 0;   
    overflow: hidden;   
    padding: 10px 10px;   
    width: 996px; 
}

P.S: I assume the rounded corners have a radius of 10px.

I knew I am late to the party but below is the correct way to deal with this, the key is to use InputStreamBody in place of FileBody to upload multi-part file.

   try {
        HttpClient httpclient = new DefaultHttpClient();
        HttpPost postRequest = new HttpPost("https://someserver.com/api/path/");
        postRequest.addHeader("Authorization",authHeader);
        //don't set the content type here            
        //postRequest.addHeader("Content-Type","multipart/form-data");
        MultipartEntity reqEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);


        File file = new File(filePath);
        FileInputStream fileInputStream = new FileInputStream(file);
        reqEntity.addPart("parm-name", new InputStreamBody(fileInputStream,"image/jpeg","file_name.jpg"));

        postRequest.setEntity(reqEntity);
        HttpResponse response = httpclient.execute(postRequest);

        }catch(Exception e) {
            Log.e("URISyntaxException", e.toString());
   }

If you do not need much customization and seek for simpleness, you can do it with built-in way - AjaxExtensions.ActionLink method.

<div class="cart">
      @Ajax.ActionLink("Add To Cart", "AddToCart", new { productId = Model.productId }, new AjaxOptions() { HttpMethod = "Post" });
</div>

That MSDN link is must-read for all the possible overloads of this method and parameters of AjaxOptions class. Actually, you can use confirmation, change http method, set OnSuccess and OnFailure clients scripts and so on

Kotlin:

If you needed to draw a bitmap in a View, scaled to FIT.

You can do the proper calculations to set bm the height equal to the container and adjust width, in the case bm width to height ratio is less than container width to height ratio, or the inverse in the opposite scenario.

Images:

// binding.fragPhotoEditDrawCont is the RelativeLayout where is your view
// bm is the Bitmap
val ch = binding.fragPhotoEditDrawCont.height
val cw = binding.fragPhotoEditDrawCont.width
val bh = bm.height
val bw = bm.width
val rc = cw.toFloat() / ch.toFloat()
val rb = bw.toFloat() / bh.toFloat()

if (rb < rc) {
    // Bitmap Width to Height ratio is less than Container ratio
    // Means, bitmap should pin top and bottom, and have some space on sides.
    //              _____          ___
    // container = |_____|   bm = |___| 
    val bmHeight = ch - 4 //4 for container border
    val bmWidth = rb * bmHeight //new width is bm_ratio * bm_height
    binding.fragPhotoEditDraw.layoutParams = RelativeLayout.LayoutParams(bmWidth.toInt(), bmHeight)
}
else {
    val bmWidth = cw - 4 //4 for container border
    val bmHeight = 1f/rb * cw
    binding.fragPhotoEditDraw.layoutParams = RelativeLayout.LayoutParams(bmWidth, bmHeight.toInt())
}

The best option is probably to use a lambda expression that closes over the variables you want to display.

However, be careful in this case, especially if you're calling this in a loop. (I mention this since your variable is an "ID", and this is common in this situation.) If you close over the variable in the wrong scope, you can get a bug. For details, see Eric Lippert's post on the subject. This typically requires making a temporary:

foreach(int id in myIdsToCheck)
{
    int tempId = id; // Make a temporary here!
    Task.Factory.StartNew( () => CheckFiles(tempId, theBlockingCollection),
         cancelCheckFile.Token, 
         TaskCreationOptions.LongRunning, 
         TaskScheduler.Default);
}

Also, if your code is like the above, you should be careful with using the LongRunning hint - with the default scheduler, this causes each task to get its own dedicated thread instead of using the ThreadPool. If you're creating many tasks, this is likely to have a negative impact as you won't get the advantages of the ThreadPool. It's typically geared for a single, long running task (hence its name), not something that would be implemented to work on an item of a collection, etc.

Step 1:

Locate phpMyAdmin installation path.

Step 2:

Open phpMyAdmin/config.inc.php in your favourite text editor. Copy config.sample.inc.php to config.inc.php if it's missing.

Step 3:

Search for $cfg['Servers'][$i]['auth_type'] = 'config';

Replace it with $cfg['Servers'][$i]['auth_type'] = 'cookie';

Walk is a good built-in for what you are doing

In SSMS, "Query" menu item... "Results to"... "Results to File"

Shortcut = CTRL+shift+F

You can set it globally too

"Tools"... "Options"... "Query Results"... "SQL Server".. "Default destination" drop down

Edit: after comment

In SSMS, "Query" menu item... "SQLCMD" mode

This allows you to run "command line" like actions.

A quick test in my SSMS 2008

:OUT c:\foo.txt
SELECT * FROM sys.objects

Edit, Sep 2012

:OUT c:\foo.txt
SET NOCOUNT ON;SELECT * FROM sys.objects

Apart from the information given by David M. Lloyd one could add that the mechanism that allows this is called target typing.

The idea is that the type the compiler assigns to a lambda expressions or a method references does not depend only on the expression itself, but also on where it is used.

The target of an expression is the variable to which its result is assigned or the parameter to which its result is passed.

Lambda expressions and method references are assigned a type which matches the type of their target, if such a type can be found.

See the Type Inference section in the Java Tutorial for more information.

If you're looking for preferred language code ("en", "de", "es" ...), and localized preferred language name (for current locale), here's a simple extension in Swift:

extension Locale {
    static var preferredLanguageIdentifier: String {
        let id = Locale.preferredLanguages.first!
        let comps = Locale.components(fromIdentifier: id)
        return comps.values.first!
    }

    static var preferredLanguageLocalizedString: String {
        let id = Locale.preferredLanguages.first!
        return Locale.current.localizedString(forLanguageCode: id)!
    }
}
