i started learn linux networking , packets filtering. in iptables documentation stated that: if packet destined box, packet passes downwards in diagram, input chain. if passes this, any processes waiting packet receive it . so, suppose there're 3 server apps on host. servers , b tcp servers , , c udp server . true, if receive udp packet, at ip level packet delivered apps a, b, c? or sockets of apps & b wouldn't receive packet @ all? tcp servers , udp servers operate in different ways. at 1 tcp server listen on given tcp port (corner cases ignored sake of simplicity). connection requests (encapsulated in ip packets) destined port "accepted" 1 process (more accurately, accepted process has file descriptor corresponding 1 listening endpoint). combination of [remote_address,remote_port] , [local_address,local_port] unique. tcp server doesn't receive "packets", receives stream of data doesn't have specific relationship underlyin...

i understand using blocking notifies thread pool block of code pass contains long-running or blocking operations. allowing pool temporarily spawn new workers ensure starvation never happens. use blocking blocks @ places thinking may not ideal continue using blocking blocks default executioncontext since there must cost associated in creating temporary workers , destroying them etc. instead create separate execution context run blocking calls avoid creation/destroying costs of worker threads have enough pool size in dedicated execution context. or it's okay use 1 executioncontext , continue using blocking blocks? basically db calls blocking , going wrapped in async{blocking{}} (if continue using 1 executioncontext). there hundred or more dao blocking apis. , potentially thousands of users hitting system.

in java, if have classa extends classx , implements interfacey , , both classx , interfacey have methodc() , why don't have give implementation of methodc() in classa ? kind of method overloading ? because if classx has implementation of methodc() , classa extends classx , classa does have implementation of methodc() - classx 's implementation of it. if classa has it's own implementation of methodc() , called method overriding - classa 's implementation override implementation of super class ( classx ). overloading different issue entirely: overloading occurs when class has multiple methods same name/return type take different parameters. useful when want able perform same or similar operations different inputs, , has nothing overriding , useful when have subclass implementation of particular method needs different of super-class. see here helpful discussion differences between them.

i have been using matlab's system command result of linux commands, in following simple example: [junk, result] = system('find ~/ -type f') this works expected, unless user types matlab's command window @ same time. during long find command not uncommon. if happens user's input seems mixed result of find command (and things break). as example, instead of: /path/to/file/one /path/to/file/two /path/to/file/three /path/to/file/four i might get: j/path/to/file/one u/path/to/file/two n/path/to/file/three k/path/to/file/four in order demonstrate easily, can run like: [junk, result] = system('cat') type command window , press ctrl+d close stream. result variable whatever typed in command window. is there safer way me call system commands matlab without risking corrupted input? wow. behavior surprising. sounds worth reporting bug mathworks. tested on os x, , see same behavior. as workaround, re-implement system() using calls ...

i wondering while "offsets" , "indices / index" are. offsets e.g. mentioned in https://github.com/mrdoob/three.js/blob/dev/src/core/buffergeometry.js , indices mentioned in indexedgeometry, can't find anymore in dev tree. although indices seem rather obvious , although dive code figure out maybe-correct answer myself i'd love hear "official" statement :) thanks! there 2 ways defining geometries: non-indexed "vertices": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, ... ], "normals": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, ... ] in mode every triangle position defined , can't reuse data. triangle 0: [ 0, 1, 2, 3, 4, 5, 6, 7, 8 ] indexed "indices": [ 0, 1, 2, ... ], "vertices": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, ... ], "normals": [ 0, 1, 2, 3, 4, 5, 6, 7, 8, ... ] in mode, indices define order of data. first triangle using indices 0 , 1 , , 2 . these indices used fetch vertices , norm...
