i'm working refactor script has reliance on 3 hashes (simple hashes), initialized @ beginning of script. in total, these hash values take on hundred lines in script. in order improve overall readability , cleanliness of code, should store information outside of script , read in information @ start? data should static (individual entries may have changed on occasion). if yes, how go storing in database/suggested storage medium? (i'm noob when comes sql). sounds have configuration data. mastering perl book has chapter discussing several choices.

i'm looking write application grab basic information mame emulator. i wondering if on here had experience that. i've done little searching , can't seem find information. i'm hoping make few hooks running emulator find out things when game starts, game starts, how many players, when player stops playing, game scores, etc. has ever heard of being done? have no idea how of possible, i'm looking explore possibilities here , pointers welcome. building mame sources doable, , result modifying sources , building doable. adding hooks application can monitor going on in particular game in mame easier task, creating sort of app app communication , having new app monitor information. mame may have these sorts of things build in there or @ least 1 gui launcher mame.

i'm go through micro-controller project controls robotic arm. problem @ ms windows there mikroelectronica (ide: microc) compile .c hex put hex in proteus , simulate. using special (pcb) kit cd (carries windows software) put microchip , install hex file or ever. first respect ms hate it! adore ubuntu/linux , open-source need experts tell me in "steps" how mentioned in linux minimal complications. the electrical , mechanical engineers along me brag ms easy. want show them how computer science guy uses open-source technology , how strong , reliable is. please ! you wish demonstrate power of linux trying run products designed operating system on it? chances tools may work in wine . or maybe can use hi-tech c compiler , try geda simulation. possible compile microchip c30 on linux if working on 16-bit pic:s. in case, may not easy using out-of the-box windows tools. more educational, nevertheless.

i running app strictmode activated in development documented here strictmode lower platform versions , noticed error message not know think nor can find reference. i android.os.strictmode$instancecountviolation values instances , limit e.g. instances=3; limit=2 now wondering: a) how limit calculated b) how can such violation happen , evasive actions. any ideas? it's in code the key strictmode.sexpectedactivityinstancecount , incrementexpectedactivitycount , decrementexpectedactivitycount : increment called in activitythread.performlaunchactivity after creating activity instance. decrement called in activitythread.performdestroyactivity after activity has been removed application. so limit less each time activity destroyed, if instance leaked real instance count bigger limit, detect if it's leaked gc magic (in decrementexpectedactivitycount ): system.gc(); system.runfinalization(); // added in https://github.com/android/...

industry standard locally scoped variables '_' js lint complains mightily these _'s. does else have naming convention locally scoped variables in javascript file we develop in .net here, , made simple decision standardize on simple convention. c# , javascript code should close 1 possible. hence, camelcase local variables, titlecase types, , on. it's worked out pretty well, since there's no jarring transition between 2 languages, , great job of distinguishing our code native js code , of 3rd party libraries. my 2 cents. p.s. use stylecop standards, fwiw. , won't make jslint happier.
