i've got kext based on apple's audioreflectordriver sample code (it intercepts audio output , makes copy). on <= 10.6, when call proc_selfpid() inside ioaudioengine subclass, reports pid of process generates audio. on 10.7, reports coreaudio_d process. what changed? know apple has documented change? there way originating process id in lion? update ... apple dts engineer has informed me that: the audio hal rewritten in lion , change side effect of effort. don't believe deliberate change, instead driven larger architectural changes in coreaudio. strictly speaking, don't believe proc_selfpid ever documented return useful in audio context, it's entirely possible information not available anymore. [....] the problem not kernel returing wrong pid, instead coreaudio's architecture has changed such audio coming different process. still waiting hear him if there's way info in 10.7. my suspicion wasn't documented because rewrite di...

there in project major db server, , other servers installed @ different places maintain own local databases. have allow every system update local database version on major db. servers runs java environment. there seems many ways transfer files: simple web download page, web-service, ftp, socket.. think fits better situation? the general procedure looks like: 1, client sends string of version server. 2, server generates patch , sends back. (since patch maybe huge, should separated parts) and i'm thinking inside procedure 2. there lot of choices. 1, should @ first count rows fetched , calculate how many parts should divided. and meet choice, should send number of parts or list of links client, , client uses links request each part if connection based on web request, or can push parts 1 one if servers connected socket, or can following step: 2, can fetch needed records server database part part, each time limited rows, return java list, serialize list file in orde...

i'm trying implement key/value store mysql i have user table has 2 columns, 1 global id , 1 serialized data. now problem everytime bit of user's data changes, have retrieve serialized data db, alter data, reserialize , throw db. have repeat these steps if there very small change of user's data (since there's no way update cell within db itself) basically i'm looking @ solutions people use when faced problem? maybe should preprocess json data , insert data proper mysql row separated fields. since input json, have various alternatives converting data: you mentioned many small changes happen in case. occur? happen in member of list? top-level attribute? if updates occur in list members in part of json data, perhaps every member should in fact represented in different table separate rows. if updates occur in attribute, represent field. i think cost of preprocessing won't hurt in case.
