java - Crypto Miner using - Stratum Mining Protocol -


i newbie , trying write crypto miner in java .. using stratum protocol .. below java code .. not sure how mining job notification?

1) connected pool using - mining.subscribe 2) , requested mining authorization - mining.authorize

then how notify response - can please help.

stratum protocol says *"server start sending notifications mining jobs server sends 1 job almost instantly after subscription. small engineering note: there's reason why first job not included directly in subscription response - miner need handle 1 response type in 2 different way; firstly subscription response , standalone notification. hook job processing json-rpc notification sounds bit better me."*

static boolean connect2pool(string server, int port) {     string message1 = "{\"id\":1,\"method\":\"mining.subscribe\",\"params\":[]}";     string authorizemessage = "{\"params\": [\"" + username + "." + worker + "\", \"" + password + "\"], \"id\": 2, \"method\": \"mining.authorize\"}";      boolean result = false;     datainputstream is;     dataoutputstream os;      try     {         inetaddress address = inetaddress.getbyname(server);         system.out.println("atempting connect " + address.tostring() + " on port " + port + ".");           // connect           socket socket = new socket();         socket.connect(new inetsocketaddress(server, port));         = new datainputstream(socket.getinputstream());         os = new dataoutputstream(socket.getoutputstream());         printwriter pw = new printwriter(os);         pw.println(message1);                                       //connect         pw.flush();          //read response          bufferedreader in = new bufferedreader(new inputstreamreader(is));         jsonobject json = new jsonobject(in.readline());          if(!json.has("result")) {             system.out.println("no reult");             result=false;         }else {             system.out.println("json response: " + json.tostring());             result=true;         }          pw.println(authorizemessage);                               //authorize         pw.flush();          //read response          in = new bufferedreader(new inputstreamreader(is));         json = new jsonobject(in.readline());          if(!json.has("result")) {             system.out.println("no reult");             result=false;         }else {             system.out.println("json response: " + json.tostring());             result=true;         }           is.close();         os.close();         socket.close();       } catch (ioexception e) {         system.out.println(e.getmessage());         system.out.println("not able connect pool");         system.exit(-2);     } catch (jsonexception e) {         system.out.println(e.getmessage());         system.out.println("json not good.");         system.exit(-2);     }       return result;  } //end of connect2pool

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
