please , thank you

public void writecounttofile() {     try {         outputstreamwriter outputstreamwriter = new outputstreamwriter(openfileoutput("countvalue.txt", context.mode_private));         outputstreamwriter.write(string.valueof(counter));         outputstreamwriter.close();     } catch (ioexception e) {         log.v("myactivity", e.tostring());     } }   private  int readcountfromfile() {      string result = "";     int countervalue = 0;     try {          inputstream inputstream = openfileinput("countvalue.txt");          if (inputstream != null) {              inputstreamreader inputstreamreader = new inputstreamreader(inputstream);             bufferedreader bufferedreader = new bufferedreader(inputstreamreader);              string tempstring = "";             stringbuilder stringbuilder = new stringbuilder();              while ((tempstring = bufferedreader.readline()) != null) {                  stringbuilder.append(tempstring);              }              inputstream.close();              result = stringbuilder.tostring();             countervalue = integer.parseint(result);          }       } catch (filenotfoundexception e) {         log.v("myactivity", "file not found" + e.tostring());     } catch (ioexception e) {         e.printstacktrace();     }     return countervalue; }

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 ...
