javascript - underscore.js templating, iterating over "this" -

May 15, 2013

how iterate on "this" (or data object passed template) using underscore.js templating? example, if pass data object template: obj = {name: "ben", description: "funny looking"} var template = _.template("<ul> <% _.each(this, function(x, y){ print('<li>'+x+'<li>')}) %> </ul>"); var compiled = template(obj); i expect "this" in iterator loop on data object (like in handlebars), it's not working. ordinarily i'd directly enter <%= name %> template, in case, object keys being determined dynamically. any ideas on how this? thanks! here's easy solution: var compiled = template({data:obj}); and iterate on "data"

Cocos2d 2.0 - 3 numbers on the bottom left -

May 15, 2013

i have 3 numbers on bottom left part of screen on cocos2d 2.0 project: 82 0.016 60.0 60 fps , other two? remember, previous versions of cocos had fps number. any clues? thanks 82 <-- number of draw calls 0.016 <-- time took render frame, here: 1.0/60.0 = 60 fps 60.0 <-- frames per second the first number (82) number of draw calls (which high). typically each node renders on screen (sprites, labels, particle fx, etc) increases number one. draw calls expensive, important keep number down. 1 way batching draw calls - cocos2d v3 automatically. the time took render frame, in seconds. since need draw new frame every 0.016666666 seconds in order achieve 60 frames per second ( 1/60 = 0,0166… ) it's inverse of framerate. the last number number of frames per second aka framerate aka fps. value, previous one, averaged on several frames doesn't fluctuate much. note ios devices have vsynch (vertical synchronization) on. game can render frame every 0.0...

i creating android app requires using android phone's name store information phone. name of phone changing. however, when other phones perform multiple bluetooth scans, seem use first name recognized phone, after phone name has changed. there way force android app see new name or flush kind of cache bluetooth scan has finished? as noted in howell's answer can use setname change name, , can use fetchuuuidswithsdp() force update of name of phone, believe there no way force device update service information , name has you. i guess best can create new connection , hope that triggers update info has on you, if worked implementation dependent (i.e. not reliable), because has no need to.

how can i recover windows chk-files extensions in linux bash -

May 15, 2013

after scan disk have lot of chk-files in folders "found.000", ... i can find out extensions file command: for in /media/daten/found.*/*.chk ; file $i; done how can use reconstruct file extensions these files? this technique not work files. used use data recovery. for in /media/daten/found.*/*.chk; mv "$i" "$i".$(grep $(file -bi $i | awk '{print $1}' | sed 's/;//') /etc/mime.types | head -1 | awk '{print $2}'); done the way works uses mime type functionality in file command greps /etc/mime.types it, picks first extension in list , renames file that. this command mass renames, move first , ask questions later, 100% sure you're running on correct directory. next time, not use chkdsk recover files. can damage them beyond repair. chkdsk om nom nom data , burp afterwards. use recovery software files need before chkdsk. generally, files named .chk though, not .chk (just fyi.)
