what things can when it's necessary show many objects , calculate position, collision detection, reaction, etc. , want smoothly? here's example i'm developing. want if have 100 balls on screen, can show them smoothly. don't have idea of how it. every suggestion appreciated. the basic steps improve performance in canvas can seen in html5 rock's canvas performance tutorial . and, if free handle collision detection without box2d, check quad-tree implementation . quad-tree doesn't deals collisions directly can improve performance reducing amount of comparisons needed detect collisions. articles suggestion further reading: broad phase collision detection using spatial partitioning collision detection , response making games box2dweb

the issue i'm trying solve follows: i have process ingests data file , inserts things in multiple tables, done 1 transaction, large data sets rollback or commit time out , fail, no matter set time out (at least far attempts have shown me). decided need rewrite functionality "chop" task up. stands pseudo code current code looks (pseudo code used avoid unnecessary information) variable = functionthatreadsfromafile(); itransactionmanager transactionobject = new transactionmanager(); idbtransaction dbtransaction = transactionobject.get(); writetofirsttable(variable ,dbtransaction); writetosecondtable(variable ,dbtransaction); writetothirdtable(variable ,dbtransaction); if(!error) transactionobject.commit(dbtransaction); else transactionobject.rollback(dbtransaction); like said, works fine smaller data sets, when file has more particular amount of rows (dependent on time out) fails on commit or rollback. i can't change time out 10,000 seconds example, in fac...

i use recovery strategy. somehow ended in position 1 commit dropped 3 days worth of commits. and got pushed . committer isn't sure whether did forced push or what, we're in position. , 10 additional commits have been pushed since "bad" one. all of old commits there , piece together, i'm hoping git can me out. suppose cherry-pick range of commits between point , point b, there better? most, not all, of changes local 1 directory , i'd rather not manually inspect each one. what's right approach here remembering has been pushed upstream? git reset --hard <one commit before bad commit> git cherry-pick <the range of commits you've lost> git pull this way simulate on last commit (with reset ). create new commits locally ( cherry-pick ). pull in changes (and maybe merge conflicts).

i'm practicing ruby meta-programming , trying write own loop method handle of ugliness in listening socket, give programmer chance specify loop break condition , block of things after each io.select/sleep cycle. what want able write this: x = 1 while_listening_until( x == 0 ) x = rand(10) puts x end what i've been able make work is: def while_listening_until( params, &block ) break_cond = params[ :condition ] || "false" loop { #other listening things happening here yield break if params[:binding].eval( break_cond ) } end x = 1 while_listening_until( :condition => "x==0", :binding => binding() ) x = rand(10) puts x end so, how make eval , binding ugliness go away? this lambdas handy: def while_listening_until( condition, &block ) loop { #other listening things happening here yield break if condition.call } end x = 1 while_listening(lambda{ x == 0 }) x = rand(10) puts x en...

i think must missing obvious, can't use preventdefault cancel navigating link's href when link tapped on ipad (it works ok on android phone though). i have simple test page, has on: <a id="mn" href="http://www.google.com">some link</a> <script> document.write('<script src=js/' + ('__proto__' in {} ?
