when app moves background while either playing audio or recording audio, provide the green "in call" status bar appears when in call , swap out app, giving quick "return app" capability. i thought might private api, noticed griffin italk app when recording audio (see picture) - know can done, have not been able figure out api (the info.plist setting, avaudiosession , uiapplication/delegate or whatever) make magic happen. app working , recording audio in background , works fine, assume there bit somewhere i'm not setting behavior. can either point me right docs or sample code exhibits behavior? (i've scoured audio docs , haven't been able find it). thanks! there may private api this, if want app store, thing register voip app , gets in-call status bar, skype or (i imagine) italk.

i'm using old version of jbpm workflow processing part of larger project. i'm investigating possibility of moving drools flow library replacement jbpm. i've found lot of documentation migrating osworkflow drools, can't find migrating jbpm drools flow. there similar, automatic tools migration jbpm? , if not, there documentation describing steps involved in manual migration? there should 1 jbpm5 direct port of drools flow. jbpm5 uses drools maven artifacts internally , far know, jboss has been trying merge 2 projects time. of course can still use drools integration, drools expert jbpm5, , use eclipse drools editors modify it's bpmn 2.0 processes. digress. the migration tool not out yet bet ask author directly that: http://community.jboss.org/wiki/jbpm5migrationtoolproject

lately have been playing around plugin framework provided qt4 framework, , works perfectly. there 1 thing unsure of. in examples, interfaces implemented (the actual plugin), had source code available (the person implementing interface has access interface source). not problem, rather expose interface via shared library or similar. my aim give 3rd party developers shared library file, can "import" (excuse java terminology) in code create plugins application. similar giving .jar file in java developer can import. the reason behind not hide source code, open source project, simplicity sake. also, program dependant on interfaces staying way plugins different 3rd parties can talk each other. if mess actual interfaces, fall apart. i appreciate nudge in correct direction. thanks! c++ not allow introspection java, therefore cannot ship "the binaries" , infer interface that. in c++ need textual description of interface (the header files). someone wa

i have confusion regarding multi screens support in android. have gone through article multi screen support @ android developer forum. question if app has 15-20 images need shown full screen on device screen. if want support screens should put in 3 drawable folders ldpi, mdpi & hdpi. here have done in ldpi - images of 240x320 resolution mdpi - images of 320x480 reolution hdpi - images of 720x800 resolution. (i using same densities 3 resolution) think not right approach. what should do? put images of different resolution in drawable-ldpi, drawable-mdpi & drawable-hdpi above or should use images of different densities 120 dpi, 160 dpi & 240 dpi. if use images of different densities should resolution(should 120 dpi resolution 240x320, 160 dpi resolution 320x480 & 240 dpi resolution 480x800). or if using different dpi images resolution should same(320x480) densities . regards, anuj ideally should have drawables different densities different screens. can u

does know how export/transfer single project 1 tfs server another? i have 2 tfs servers @ work, old 1 (demo1) started off demo thing , stayed in use, , new server: tfs1. all done before time , i've had deal issues. most of projects didn't need history/branch info. 1 did. unfortunatly decided long while ago move projects (no history straight copy off file) except 1 large project. this means tfs1 has own history on bunch of smaller projects , demo1 solely used large project. we want move 1 project , history, (branches less important can take straight copies of release code) does know how export/transfer single project 1 tfs server another? there tool out there can sort of thing? you should start taking @ tfs integration platform on codeplex. used tfs tfs migration tool. you'll have modify tool pretty pick history. it's been while since we've used it, pretty straightforward modify. alternatively, write specific-purpose tool relatively you

i posted an earlier version of yesterday , cannot seem add version posting because seems have closed posting editing, here new version in new posting. i have script below following things: 1.) plot best fit curve sigmoidal data. 2.) re-size data based on new max , min coordinates x , y. 3.) calculate , plot new best fit curve resized data. steps 1 , 2 seem work fine, step 3 not. if run script, see plots totally invalid curve re-sized data. can show me how revise code below creates , plots true best fit sigmoidal curve re-sized data? needs reproducible when re-sized across spectrum of possible max , min values. i seem able track problem new_p, defined in following line of code: new_p, new_cov, new_infodict, new_mesg, new_ier = scipy.optimize.leastsq( residuals,new_p_guess,args=(newx,newy),full_output=1,warning=true) but cannot figure out how deeper problem that. think problem may have difference between global , local variables, perhaps else. here curre

i can't find applet or program online convert context free language push down automata... appreciated. it easy hand. pda has start state s , final state f, 2 states has. make transition ((s, empty, empty),(f, s)), s start symbol of cfg. each rule x -> y, x non terminal symbol , y possibly empty string of terminals , nonterminals, make transition ((f, empty, x),(f,y)). finally, each terminal symbol a, add rule ((f, a, a),(f, empty)). what start pushing start symbol on stack. replaces nonterminal finds @ top of stack right hand side of production rule, , matches , pops terminal characters @ top of stack.

i'm looking fast code 64-bit (unsigned) cube roots. (i'm using c , compiling gcc, imagine of work required language- , compiler-agnostic.) denote ulong 64-bit unisgned integer. given input n require (integral) return value r such that r * r * r <= n && n < (r + 1) * (r + 1) * (r + 1) that is, want cube root of n, rounded down. basic code like return (ulong)pow(n, 1.0/3); is incorrect because of rounding toward end of range. unsophisticated code like ulong cuberoot(ulong n) { ulong ret = pow(n + 0.5, 1.0/3); if (n < 100000000000001ull) return ret; if (n >= 18446724184312856125ull) return 2642245ull; if (ret * ret * ret > n) { ret--; while (ret * ret * ret > n) ret--; return ret; } while ((ret + 1) * (ret + 1) * (ret + 1) <= n) ret++; return ret; } gives correct result, slower needs be. this code math library , called many times various func

i work programmer, have no computer science background, i've been following along excellent mit opencourseware intro computer science , programming. in course of which, question asked: "will program written using function definitions , calls, basic arithmetic operators, assignment , conditionals run in constant time?" i thought answer yes, since of these operations seem pretty simple. smart people knew, correct answer no, apparently because of potential indefinite recursion. it seems don't understand implications of "in constant time". way pictured meaning, sounded meant simple operation take known amount of time complete. accept recursion can lead program running forever, aren't individual operations still taking finite , measurable amount of time each... if there infinite number of them? or answer mean 2 infinitely recursive programs cannot validly said take same amount of time run? if can give me authoritative definition of "in con
