java.text.SimpleDateFormat#parse has different behaviour between Scala and Clojure -


i'm trying assign pdt string java.util.date using simpledateformat.

scala, gives me right format pdt (utc-07:00), or without setting timezone os timezone "america/los_angeles".

scala> import java.util.timezone import java.util.timezone  scala> import java.util.date import java.util.date  scala> import java.text.simpledateformat import java.text.simpledateformat  scala> timezone.getdefault res0: java.util.timezone = sun.util.calendar.zoneinfo[id="america/los_angeles",offset=-28800000,dstsavings=3600000,usedaylight=true,transitions=185,lastrule=java.util.simpletimezone[id=america/los_angeles,offset=-28800000,dstsavings=3600000,usedaylight=true,startyear=0,startmode=3,startmonth=2,startday=8,startdayofweek=1,starttime=7200000,starttimemode=0,endmode=3,endmonth=10,endday=1,enddayofweek=1,endtime=7200000,endtimemode=0]]  scala> val df = new simpledateformat("yyyy-mm-dd't'hh:mm:ssxxx") df: java.text.simpledateformat = java.text.simpledateformat@fe8c5ede  scala> df.parse("2017-10-28t23:59:59-07:00") res1: java.util.date = sat oct 28 23:59:59 pdt 2017

but clojure parses date in utc format (:utc-00:00),

without .settimezone, 

aws-creds.core=> (import 'java.util.timezone) java.util.timezone  aws-creds.core=> (timezone/getdefault) #object[sun.util.calendar.zoneinfo 0x28ce2a1 "sun.util.calendar.zoneinfo[id=\"america/los_angeles\",offset=-28800000,dstsavings=3600000,usedaylight=true,transitions=185,lastrule=java.util.simpletimezone[id=america/los_angeles,offset=-28800000,dstsavings=3600000,usedaylight=true,startyear=0,startmode=3,startmonth=2,startday=8,startdayofweek=1,starttime=7200000,starttimemode=0,endmode=3,endmonth=10,endday=1,enddayofweek=1,endtime=7200000,endtimemode=0]]"]  aws-creds.core=> (import 'java.util.date) java.util.date  aws-creds.core=> (import 'java.text.simpledateformat) java.text.simpledateformat  aws-creds.core=> (let [df (new simpledateformat "yyyy-mm-dd't'hh:mm:ssxxx" )]             #_=>   (print (.parse df "2017-10-28t23:59:59-07:00"))) #inst "2017-10-29t06:59:59.000-00:00"nil

same behaviour .settimezone america/los_angeles, 

aws-creds.core=> (let [df (new simpledateformat "yyyy-mm-dd't'hh:mm:ssxxx" )]             #_=>   (.settimezone df (timezone/gettimezone "america/los_angeles"))             #_=>   (print (.parse df "2017-10-28t23:59:59-07:00"))) #inst "2017-10-29t06:59:59.000-00:00"nil

which strange, since in both cases i'm using java.text.simpledateformat. curious why simpledateformat#parse scala stores date in pdt format while clojure in utc format?

looks clojure repl prints dates in utc.

if call tostring() on date, prints date scala repl (which believe implicitly calls tostring when printing objects) does, , in system time zone:

user=> (let [df (new simpledateformat "yyyy-mm-dd't'hh:mm:ssxxx" )]   #_=>   (print (.tostring (.parse df "2017-10-28t23:59:59-07:00")))) sat oct 28 23:59:59 pdt 2017nil

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
