can java class file decompiled such way show code added compiler? example, java compiler inserts no argument constructor whenever no explicit constructor found. when decompile class file no explicit constructor, however, 1 inserted compiler doesn't show up. example compiler's insertion of "extends java.lang.object" in class doesn't explicitly extend other class. again, when decompile such class, i'm not seeing "extends" component of class declaration in decompiled text. perhaps i'm taking fact java compiler "inserts" code literally? maybe need more sophisticated decompiler? better use byte code viewer asmifier asm . instructions added compiler skipped @ decompiling, in order keep source code , decompiled code close. you find default constructor signature public <init>()v . added byte code if no constructor defined.

i have function little reading, lot of writing ram. when run multiple times on same core (the main thread), runs 5x fast if launch function on new thread every run (which doesn't guarantee same core used between runs), launch , join between runs. this suggests cache being used heavily write process, don't understand how. thought cache useful reads. modern processors have write-buffers. reason writes are, first approximation, pure sinks. processor doesn't have wait store reach coherent memory hierarchy before executes next instruction. (aside: stores not pure sinks. later read written-to memory location should return written value, processor must snoop write-buffer, , either stall read or forward written value it) obviously such buffer(s) of finite size, when buffers full next store in program can't executed , stalls until slot in buffer made available older store becoming architecturally visible. ordinarily, way write leaves buffer when value writt...

sending audio speaker playback on android easy, possible copy of actual final digital signal? let's have 2 apps running "myapp" , "someotherapp". app sends audio speaker, "someotherapp". "someotherapp" not app - it's 3rd party app. possible copy of mixed audio signal played speaker os? is, audio signal mixture of speaker signal app , speaker signal "someotherapp". to summarize: looking way hook low-level audio path (hal audio stream out - after mixing!) can copy of "final" speaker signal (in real-time). optimally, hook low-level microphone path, that's less of concern right now. looks short answer no . longer 1 kinda . , sorta . not really, far know. option 1: might problem respects privacy. (not option) option 2: nobody thought needed, did not build system. option 3: amount of trouble shooting when programmers use wrong source not worth it. edit - can, of course, record input .
