go - Grab output from container in Docker SDK -


i'm trying run container using docker sdk golang , can't output container. i'm using following code that runs container, doesn't sends stderr , stdout of application. can advice i'm doing wrong?

type dckr struct {     cli      *client.client     username string     password string     addr     string     ctx      context.context }  func (d *dckr) run(containername string, image string, command []string, bind []string, stdout io.writer, stderr io.writer) error {     log.printf("[create] %s -> %s \n", image, containername)      res, err := d.cli.containercreate(         d.ctx,         &container.config{             user:         "root",             attachstdout: true,             attachstderr: true,             image:        image,             cmd:          command,         },         &container.hostconfig{             autoremove: true,             binds:      bind,         },         &network.networkingconfig{},         containername,     )      if err != nil {         log.println("[create] failed. %s", err)         return err     }     defer d.cli.containerremove(d.ctx, res.id, types.containerremoveoptions{force: true})      log.printf("[create] id: %s \n", res.id)     wrn := range res.warnings {         log.printf("[create] %s \n", wrn)     }      rsp, err := d.cli.containerattach(d.ctx, containername, types.containerattachoptions{         stream: false,         stdout: true,         stderr: true,         logs:   true,     })      if err != nil {         log.printf("[attach] fail. %s \n", err)         return err     }     log.printf("[attach] %s", res.id)     defer rsp.close()      err = d.cli.containerstart(d.ctx, res.id, types.containerstartoptions{})     if err != nil {         log.printf("[run] fail. %s \n", err)         return err     }      _, err = stdcopy.stdcopy(stdout, stderr, rsp.reader)     return err }

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
