i seeing code, in have statement (char *)(emsg+1) given, i guess (char *) emsg might have been string, + 1 here? emsg pointer type (e.g. int ). emsg + 1 increments pointer 1, i.e. points initial address + sizeof(int) . then, (char*) (emsg + 1) cast, i.e. end result casted char* pointer, end pointer-to-char points initial address + sizeof(int) . in general, char* pointers characters, i.e. c -like 0 terminated strings, not case. convert pointer char* when want "extract" smallest unit of addressable memory, on machines char* pointer underlying type of 1 byte ( char ).

we have timezone-unaware scheduler in pure python. it uses heapq (a python binary heap) of ordered events, containing time, callback , arguments callback. gets least-valued time heapq, computes number of seconds until event occur, , sleeps number of seconds before running job. we don't need worry computers being suspended; run on dedicated server, not laptop. we'd make scheduler cope timezone changes, don't have problem in november did (we had important job had adjusted in database make run @ 8:15am instead of 9:15am - runs @ 8:15am). i'm thinking could: store times in utc. make scheduler sleep 1 minute , test, in loop, recomputing “now” each time, , doing <= comparison against job datetimes. jobs run more once hour should “just run normally”. hourly jobs run in between 2:00am , 2:59am (inclusive) on time change day, should skip hour pst->pdt, , run time pdt->pst. jobs run less hourly should avoid rerunning in either case on days have time ch...

(x - xa)² + (y - ya)² + (z - za)² = r² (x - xb)² + (y - yb)² + (z - zb)² = r² (x - xc)² + (y - yc)² + (z - zc)² = r² |x y z 1| |xa ya za 1| |xb yb zb 1| = 0 |xc yc zc 1| subtracting first equation second , third, rid of quadratic terms.
