hello , in advance, i came upon issue trying plot piecewise function in mathematica. when entered directly plot function, piecewise did not plot. however, when defined piecewise variable, did plot. why issue occurring , can still join plot? (i join setting exclusions none) the following code: (i define maxwell strain function , trying model plastic deformation of polymer on multiple stress cycles) z = 2*10^10; h = 10^12; maxwellstrain[s_, t_] := s/z + (s*t)/h; stress = {0, 10^7, -10^7, 5*10^6, 10^7, -5*10^6}; time = {0, 100, 200, 300, 400, 500}; strainlist = join[{0}, table[maxwellstrain[stress[[i + 1]], t - time[[i]]], {i, 1, 5}]]; plot[ piecewise[ table[{ total[strainlist[[1 ;; + 1]]], time[[i]] < t < time[[i + 1]]}, {i, 1, 5} ], exclusions -> none] , {t, 0, 500} ] x = piecewise[ table[{ total[strainlist[[1 ;; + 1]]], time[[i]] < t < time[[i + 1]]}, {i, 1, 5} ], exclusions -> none] plot[x, {t, 0, 500}] the fol...

at moment downloading images remotely using uiimageview category. while image downloading use placeholder image stored in xcassets folder. is worth having multiple placeholder images different sizes: small, medium, , large? or worth having 1 placeholder image , using throughout application? does size of placeholder image affect performance? well, should have @2x , @3x version of images, mean less work cpu scale / down image on different devices. also, there technically work done cpu scale image or down. however, apple's graphics processor pretty efficient @ scaling images. so technical answer "yes, affect performance", in reality not big enough difference notice. now, if have built poorly written app displays hundreds of these placeholders in uiscrollview instead of form of uicollectionview (which displays on screen, or on screen), notice slight performance difference images adds large performance difference.

i'm developing interface using asp.net ajax webforms. shows update panel upon initialization of page , after various actions requested validate user pin number. interface used on tablets, created keypad buttons collect user's pin number looks this: when buttons clicked run: protected void btn0_click(object sender, eventargs e) { addnumbertopin("0"); } the procedure call labeled number argument strdigit defined as: protected void addnumbertopin(string strdigit) { txtpin.text += strdigit; if (txtpin.text.length == 5) { ... ...check database validate pin ... } } this works, slow because every button click creates round trip web server. seems should simple store collected pin in local variable on client , post server once 5 digits have been collected. i'm new web programming, i'm not sure how go doing this. i've read this , this , still can't figure out how buttons stop posting server. ...

i started programming on ruby @ codecademy can compile codes on doing website? when making lessons on c used codeblocks run codes. know text editor can run html code. ruby? thank you. i'll take stab @ answering question think you're asking, i'm not 100% sure here. ruby interpreted language (what mean? not whole lot nowadays. if you'd more in depth discussion on distinction or lack thereof between interpreting vs compiling, read jorg's comments below). execute ruby code, you'll need install ruby. fortunately you, freely available on major platform. if you're on unix-y (eg, linux or mac), i'd recommend installing ruby via rvm or rbenv. if you're on windows, can either go cygwin route , pretend it's unix-y environment, or there prebuilt installers out there. googling 'install ruby' should have sites can @ or near top of search results.

i have been looking around on how bring string, const char* output = "ヽ(⌐■_■)ノ♪♬"; to clipboard. setclipboarddata(cf_unicodetext, hmem); i have tried multibytetowidechar, have gotten noise , conflicting claims cannot save utf-16le clipboard (wchar_t). confused. direction or code sample great. windows uses utf-16le. string should created l prefix. use utf8 can declare string u8 prefix. example: const char* text = u8"ヽ(⌐■_■)ノ♪♬e"; then have use multibytetowidechar convert utf8 utf16 , use in winapi. note use u8 need newer compilers vs2015. it's easier use utf16 in first place. example: const wchar_t* text = l"ヽ(⌐■_■)ノ♪♬e"; int len = wcslen(text); hglobal hmem = globalalloc(gmem_moveable, (len + 1) * sizeof(wchar_t)); wchar_t* buffer = (wchar_t*)globallock(hmem); wcscpy_s(buffer, len + 1, text); globalunlock(hmem); openclipboard(null); emptyclipboard(); setclipboarddata(cf_unicodetext, hmem); closeclipboard();
