can explain what's difference between gen_server:start() , gen_server:start_link() ? i've been told it's multi threading stuff. edit: if gen_server called multiple threads, execute them @ once ? or create concurrency between these threads? both functions start new gen_server instances children of calling process, differ in gen_server:start_link/3,4 atomically starts gen_server child , links parent process . linking means if child dies, parent default die. supervisors parent processes use links take specific actions when child processes exit abnormally, typically restarting them. other linking involved in gen_server:start_link case, there no multi-process aspects involved in these calls. regardless of whether use gen_server:start or gen_server:start_link start new gen_server , new process has single message queue, , receives , processes messages 1 @ time. there nothing gen_server:start_link causes new gen_server process behave or perform differe...

which 1 of 2 faster (c++)? for(i=0; i<n; i++) { sum_a = sum_a + a[i]; sum_b = sum_b + b[i]; } or for(i=0; i<n; i++) { sum_a = sum_a + a[i]; } for(i=0; i<n; i++) { sum_b = sum_b + b[i]; } i beginner don't know whether makes sense, in first version, array 'a' accessed, 'b', might lead many memory switches, since arrays 'a' , 'b' @ different memory locations. in second version, whole of array 'a' accessed first, , whole of array 'b', means continuous memory locations accessed instead of alternating between 2 arrays. does make difference between execution time of 2 versions (even negligible one)? i don't think there correct answer question. in general, second version has more twice iterations (cpu execution overhead), worse access memory (memory access overhead). imagine run code on pc has slow clock, insanely cache. memory overhead gets reduced, since clock slow running same loop twice ...

why printf behave in such uncommon way? > printf %.0f 2.5 > 2 > printf %.0f 2.51 > 3 is there advantage of behaviour compensates probable misunderstandings (like this one )? it's not strictly round-down: > printf '%.0f\n' 2.5 2 > printf '%.0f\n' 3.5 4 this form of rounding used combat bias if rounding large number of values; half of them rounded down, other half rounded up. rule is, round down if integer portion even, if integer portion odd. this is, however, explanation of particular rounding scheme, not guaranteed used implementations of printf .
