rename - I am trying to append today's date to pdfs in a subfolder using a .bat file. Right now I have: -


new -- trying make .bat file rename files in subfolder, (i want behave %folder% rather using actual location), adding prefix, abs_ 123, today's date, _20170818

right have (pseudo): 

@echo off %subfolder% (*) ren "%%a" "pre %%a" (*) ren "%%~a" "%%~na ("_%%date)%%~xa"

i agree compos , mofis comments, imo there lot of outdated variants proposed here on with:

  • locale/user settings dependent %date% , %time% variables or
  • the clumsy parse wmic variant it's cr/cr/lf sequences.
  • j-/vbscript solutions require either temp file or hybrid version difficult understand newbies.

using/parsing powershell comes @ small delay, used once in script shouldn't matter.

you may insert day offset different dates.

@echo off /f %%y in (     'powershell -nop -c "(get-date).adddays(-1).tostring(\"yyyy-mm-dd\")"' ) set yesterday=%%y echo yesterday = %yesterday%  /f %%d in (     'powershell -nop -c "(get-date).adddays(0).tostring(\"mm\/dd\/yyyy\")"' ) set "dt=%%d" echo today mdy = %dt%  /f %%t in (     'powershell -nop -c "(get-date).adddays(+1).tostring(\"yyyy\/mm\/dd\")"' ) set tomorrow=%%t echo tomorrow  = %tomorrow%  /f %%o in (     'powershell -nop -c "(get-date).adddays(0).tostring(\"o\")"' ) set iso8601=%%o echo iso8601   = %iso8601%  /f "delims=" %%u in (     'powershell -nop -c "(get-date).adddays(0).tostring(\"u\")"' ) set utc=%%u echo utc       = %utc%  /f "delims=" %%f in (     'powershell -nop -c "(get-date).adddays(0).tostring(\"f\")"' ) set fulldt=%%f echo fulldt    = %fulldt%

output on german locale system, day-/month names come in locale.

yesterday = 2017-08-17 today mdy = 08/18/2017 tomorrow  = 2017/08/19 iso8601   = 2017-08-18t17:06:46.1050969+02:00 utc       = freitag, 18. august 2017 15:06:46 fulldt    = freitag, 18. august 2017 17:06:46

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 ...
