How to approach Java 2D performance variations between different computers? -

-

i've been designing card game in java on windows. runs on laptop , few others, on lot of other systems (even few newer ones both mac , windows) animation incredibly slow.

i've found user interface toolkits java best resource far, haven't been able make significant improvement. i'm using awt/swing libraries.

question:
looking @ my game, (<1.5mb), how on computers (of similar spec) performance seems less on laptop? entire app event-driven , i've done of optimization reckon done given implementation.

i have feeling memory-related. create (compatible) , store images array @ start, , reference them there.

note: decided make game can learn , practice new ideas, i'm not trying share - i'm interested find out what's going on here.

on not operating systems, java 2d rendering pipeline supports hardware acceleration gpu. depends on java implementation you're using.

one of new features oracle's java se 7 implementation (which coming out @ end of month) this: xrender pipeline java 2d means have better performing 2d graphics on linux.

for windows, in java se 6 update 10 there improvements make java 2d perform better using direct3d hardware acceleration (source).

linux - Using a Cron Job to check if my mod_wsgi / apache server is running and restart -

my group , running server based upon django , uses mod_wsgi run apache server. not working on project after over, attempting set cronjob similar functionality check if apache server has shut down(system restart or power failure), , if has, restart server me. i've found documentation on how check if apache server down , restart server if is, our server uses https , our start command pretty verbose. can use functionality provided in these examples: https://askubuntu.com/questions/277389/cron-job-to-restart-apache https://www.digitalocean.com/community/tutorials/how-to-use-a-simple-bash-script-to-restart-server-programs or need more complicated process make happen? the command use start server is python manage.py runmodwsgi --host 0.0.0.0 --port 8001 --https-port 8000 --ssl-certificate (certificate location) --server-name (domain name) i'm pretty new linux , using both mod-wsgi apache appreciated. you better off using --setup-only option mod_wsgi-expres

actionscript 3 - TweenLite does not work with object -

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
