i integrating twitch user account api platform , had through api see if there callback section of sort send update server when user starts streaming, can't seem find reference one. is there services offer sort of thing? if not, best way of running regular checks on of users in database see when streaming, of course doing alone kill server database queries, i'm stuck go now. what looking receive callback , create post in social feed user has started streaming. based on discussions @ links below, api doesn't support webhooks , won't anytime soon. instead, expect use polling. set worker process makes requests periodically, such every 5 minutes, creates appropriate social feed posts, etc. can batch them if have bunch of channels check (exaple from github issue): https://api.twitch.tv/kraken/streams?channel=riotgames,dota2ti,machinima,esltv_hearthstone https://github.com/justintv/twitch-api/issues/211 https://discuss.dev.twitch.tv/t/notifications-using...

assume allocate space using malloc. can check whether continuous memory remains within cpu's cache (or better within cache levels l1, l2, l3 etc.) in run-time ? determining content of cpu cache low level , beyond c can do. in fact, caching transparent code may writing cpu pretty decides cache , cannot afford waste timein convoluted logic on how so. quick googling on specific tools effect came intel tuning guide , performance analysis papers: https://software.intel.com/en-us/articles/processor-specific-performance-analysis-papers . obviously, vendor specific. amd have specific tools.
