javascript - JS: ArrayBuffer of Unknown Size -

i have big object want store in arraybuffer (let uint8array). note: not know how big object is. i have logic setting values in buffer. (it working if use new uint8array(100000000); example.) the problem don't know if resizing buffer efficiently possible. performance main preoccupation here. i've been thinking starting let new uint8array(100); , if need more, create new 1 double size new uint8array(200); , copy existing content on new 1 (not quite sure how). , on. what creating regular array , converting @ end uint8array ? if need 1 @ time still many per time , have need speed, need keep first array , overwrite it. can work out amount of memory need first 1 described (it not slow) keep array next ones (you'll need keep current length). every time need more, did first one. might want "free" memory time time when gets large. it poor-man's malloc() / garbage collector, yes, , assumes need of arrays strictly consecutive.

dictionary - Represent HashMap in class diagram -

i have class diagram has dictionary (in python terms) attribute. basic structure: serverentry = { creditcardobj1 : accountbalance1, creditcardobj2 : accountbalance2, ...} to clarify, creditcardobj1 instance of class creditcard while accountbalance1 integer value , other entries in dictionary. i read in java, called hashmap. in case, implement in uml class diagram. tips on how that. using visio 2007 more helpful if can explain in terms of that. there no single truth , it's merely design decision. here couple variants: if want represent hash in python application code, can go simple class right tells name represents hash. , don't need implement hash (it's done in python interpreter), fine. if implement python interpreter, need show details on how that. middle class uses 2 arrays keys , object references. left 1 uses key/object pair bundled in separate class. there more ways show hash implementation.

video - Android MediaCodec: Backlink to input -

i'm receiving video data via rtp/h.264 (profile baseline). i'm building complete nal unit (using nal (network abstraction limit) delimiter 0x09) , pushing mediacodec. afterwards i'm rendering decoded image via opengl surfacetexture. work far. now need know in rendering calls video frame rendered. need meta information attached video frame later in rendering part. my first idea use simple queue: 1) queue.offer(videoframeid) 2) mediacodec.queueinputbuffer() 3) mediacodec.deqeueoutputbuffer() 4) mediacodec.releaseoutputbuffer() then on rendering side: 1) onframeavailable(surfacetexture) 2) queue.poll() 3) render() but out of sync. there more calls mediacodec.queueinputbuffer onframeavailable(). appears if video frame build multiple nal units. are there means reference original video frame rendering? i'm limited sdk 19 api. thank you

rust - Kill child process while waiting for it -

-
i want execute process , want wait until has finished. lets spawn , wait process in thread t1: let child = command::new("rustc").spawn().unwrap(); child.wait(); now, if special event occurs (which thread t0 waiting for) want kill spawned process: if let ok(event) = special_event_notifier.recv() { child.kill(); } but don't see way it: both kill , wait take mutable reference child , therefore mutually exclusive. after calling wait no 1 can have reference child anymore. i've found wait-timeout crate, want know if there's way. obviously, can kill process yourself. child::id method gives "os-assigned process identifier" should sufficient that. the problem killing process platform-dependent action. on unix killing process handled kill function: #![feature(libc)] extern crate libc; use std::env::args; use std::process::command; use std::thread::{spawn, sleep}; use std::time::duration; use libc::{kill, sigterm}; fn main()
