i'm heavy user of intellisense in visual studio. i'm "keep hands on keyboard" , "keep them in home position" aficionado, i'm looking ways keep hands centered on a s d f     j k l ; keys as possible. whenever intellisense list pops in visual studio, if there many words in list start same letters word i'm trying select, typing first few letters hone in on selection doesn't help, since list won't jump down preferred selection until type enough characters reach first unique character in word. it's faster take right hand off j k l ; keys , reach up/down arrow keys manually scroll through list. i'd rather keep hands centered in home position, , ideally use j , k keys move , down in intellisense list (similar how j , k move , down in vim...and since use vsvim inside visual studio). the msdn intellisense documentation lists up/down arrow keys , scrolling (mouse wheel, pgup / pgdn keys, etc.) options doing this: so here q...

i have 2 pretty simple tornado-based websocket handlers running in same process, each of function on own. however, when 1 receiving large amount of data (>8mb) process blocks , other unable process messages until of data has been received. there way can around , prevent tornado blocking here? tornado works large amount of short concurrent requests. not split long request smaller ones. process blocks. why passing big amount of data using sockets? final solution depends on answer question. if don't have big requests - use haproxy in front of multiple tornado instances.

working on html control more/less operates spreadsheet - matrix of editable data cells. when comes cells derived select i'm having issue getting correct behavior when type of cell selected edit: if render select using default formatting (size = 0) user gets out-of-place behavior of select's enter-key processing: 1st enter => activates editing on cell (shows select control) 2nd enter => expands select show options user makes selection using up/dn keys 3rd enter => closes list. (problem: enter hidden "keydown" event handler) 4th enter => required trigger event listener deactivating cell edit. on other hand, if select rendered listbox (ie, size = 3, example) enter key behavior i'm looking (meaning, #2 , #3 on above list no longer required), because list displayed internally control (rather pop-up) blows cell/row sizing. so, there way "hook" 3rd enter-key event above, or other relatively straight-forward way alter select's ...

i have wpf button content has bunch of controls including checkbox. currently single-click on checkbox fires "checked" event, that's fine. what don't double-click fires "checked" event. currently double-click triggers both checkbox' "checked" event , button's "doubleclicked" event. what want double-click on checkbox should trigger button's event, not checkbox's event. checkbox should checked upon single-click. is there way that? thanks. what trying might not make best user experience because you're going have implement delay prior processing user's attempt check box. why? well, if double click checkbox, want nothing happen checkbox, want pass control button. that's totally understandable. but happens if click checkbox? @ moment release mouse button, going expect check mark appear. system can't yet know don't plan click again. so, has wait through doubleclicktime determine...

i looking generic, strict , platform independent serialization framework. , discovered called asn.1. it looks related serialization, couldn't understand is. read wikipedia article , itu article still, it's hard know. i have many questions. maybe need overall differential description of asn.1. what asn.1? does define strict datatypes? (such 32-bit integer, 1-bit boolean, etc.) is there reference implementation in c/c++? why doesn't popular apache thrift , protocol buffers or other serialization stuffs? what's pros/cons of asn.1 when compared other serialization frameworks? 1) it's serialization standard defined iso. 2) yes, although smallest space value occupy (afaik) 5 bits. 3) don't know of full one, although i'm not claiming knowing. 4) hard answer in neutral way, far i've experienced complexity, getting close full implementation hard . 5) see 4. asn.1 space efficient (protobuf may give run money) seem complex co...

my apologies n00b question, i've tried looking through infinite loop related issues they're way more complex: var replay = 1; while (replay = 1) { replay = prompt("yes(1) or no(0) ?"); } how come infinite loop? i thought while loop continue iterating while replay variable has value of 1. however doesn't stop when user input 0, or else matter. thanks in advance of input! you assigning not checking in (replay = 1) you need double equal signs == , or better yet triple equal signs === check equality in types of operands. besides, code can changed (preview: http://jsfiddle.net/nabil_kadimi/rfda5/ ): var replay; while ((replay = window.prompt("yes(1) or no(0) ?")) === '1') { /* player wants replay */; } or better (preview: http://jsfiddle.net/nabil_kadimi/pdv4m/ ): var replay; while (replay = window.confirm("replay?")) { /* player wants replay */; }
