which of these 2 alternatives better one? locking outside loops? lock (_worklock) { foreach (var resultobject in getobjecttask.result) { foreach (var key in resultobject.keys) { string value = resultobject.getvalue(key); _lockedobject.dosomething(key, value); } } } or locking when locked object accessed? foreach (var resultobject in getobjecttask.result) { foreach (var key in resultobject.keys) { string value = resultobject.getvalue(key); lock (_worklock) _lockedobject.dosomething(key, value); } } there can potentially 5-10 simultaneous operations wanting @ same time. here's surrounding code: var tasks = provider in _objectproviders select task.factory.startnew(() => provider.objects) .continuewith(getobjecttask => { // 1 of operation bodies above go here }); var tasklist = task.whenall(tasks); tasklist.wait(); // us...

i'm learning qt, , i'm wondering if it's possible create animation in ubuntu installer. as can see on screenshot, can switch between 'images' using left , right arrows. each time click on it, smooth transition executed. know if it's possible create kind of design qt, , if it's possible replace 'images' widget various controls inside. the main goal keep cross-platform compatibility (i'm coding using python), avoid using third -party library. regards, in ubuntu installer, use html, css , javascript, can same using qwebview . you can connect javascript functions qt events, need make slides pass every time press button or key on keyboard. an idea: make slides images, , build webpage shows images. can use javascript timer set time between slides. hav done add qwebview control render page. i don't want have images, widget controls in it... in case recommend take qt animation framework , powerful , easy use.

i'm looking more performant/elegant way taking first 4 bits of bytes. bytes in big endian var gpsfixstatus = (int)raw[28]; int[] remainder = new int[8]; (int = 0; < 7; i++) { remainder[i] = gpsfixstatus % 2; gpsfixstatus = gpsfixstatus / 2; } var gpsfix = byte.parse((remainder[7].tostring() + remainder[6].tostring() + remainder[5].tostring() + remainder[4].tostring())); the first half of byte b is b >> 4 assuming want shifted lower 4 bits. if want still in place, removing bottom half, it's just b & 240 // or "b & 0xf0" but looks code though former want.

i have .net c# application. in application have 2 set of code different client. we thinking of removing part of code through preprocessor. diabling part config file parameter not option us. we want simple setup like: #define debug //.... #if debug console.writeline("debug version"); #endif the issue is, our part of code distributed multiple files , multiple projects in solution. so want define globally preprocessor “debug” @ 1 place. preferably in project property or something. what best option us? look "conditional compilation symbols" on "build" page of project property dialog. can set per-build configuration.

when 1 better other? 1 faster other or difference return of false or nil? use if when have 1 truthy , 1 falsy case , don't need implicit do block. in contrast, when should used when have handle truthy case , implicit do . there no difference in speed, it's matter of using idiomatic style. (if (my-predicate? my-data) (do-something my-data) (do-something-else my-data)) (when (my-predicate? my-data) (do-something my-data) (do-something-additionally my-data)) in if case, do-something run if my-predicate? returns truthy result, whereas in when case, both do-something , do-something-additionally executed.

i started using emacs, , installed python-mode.el, along few add-ins (following jess hamrick's setup in emacs python ide ). i find myself 1 tricky issue. want edit different buffers, want able send code both of them python shell. unfortunately, when try send code file buffer using c-c | , new python buffer opened it, , can't figure out how instruct emacs send original python shell buffer. any suggestions? a report @ https://bugs.launchpad.net/python-mode would useful, turns out there not test this. however, when checking works nice here. a reason using different output-buffer might different python-version in shebang. each python version connects own process , gets own output-buffer. , running dedicated open new process/buffer every time. what's python-mode.el version? setting py-split-windows-on-execute-p nil might help.

i have looked @ question these pdfs' 1 , 2 , page , pretty understand happens if printf(some_test_string) . not understand why ensuring size of buffer vsnprintf becomes safe compared vsprintf ? what happens in these 2 cases ? case 1 char buf[3]; vsprint(buf, "%s", args); case 2 char buf[3]; vsnprint(buf, sizeof buf, "%s", args); in case 1, if string you're formatting has length of 3 or greater, have buffer overrun, vsprintf might write memory past storage of buf array, undefined behavior, possibly causing havoc/security concerns/crashes/etc. in case 2. vsnprintf knows how big buffer contain result is, , make sure not go past that(instead truncating result fit within buf ).

i'm confused ajax request in rails. i'm submitting form using ajax , fine. must handle callback, but... following tutorials hint add respond_to |format| format.js end to controler#create , place in views folder "create.js.erb" response. other tutorials suggest create js file in assets folder , handle callback js file. what's difference? , what's right way? both different ways handling callback of ajax request. suggest use js.erb file handle ajax callback because file can recognize both js ruby code , execute. for example, in controller, def create ... if @foo = true else @foo = false end in create.js.erb, can done want show/hide div based on @foo value, can write like, <% if @foo %> // js code <% else %> // else <% end %> while if create js file in assets folder not able write condition above because pure js file , creating js.erb easy way handle ajax response.
