i have tcp connection server, implemented socket , streams. during session, server can send number of messages - must read , process them all. i created thread, checks , reads data in infinite cycle: in = socket.getinputstream(); bytearrayoutputstream baos = null; byte[] buf = new byte[4096]; while(!isinterrupted()) { baos = new bytearrayoutputstream(); for(int s; ( s = in.read(buf)) != -1; ) { baos.write(buf, 0, s); if(in.available() <= 0 ) { readchunk(baos.tobytearray()); } } } but actually, it's not efficient - puts cpu under heavy load, , somehow bytes stick previous answer. what effective , elegant way resolve situation? tcp not message-oriented, it's stream-oriented. means if send 2 messages aa , bb, it's quite possible read on different occasions values aabb, a b b, abb, aab b, aa bb (where spaces indicate different read attempts). you need handle either message size or message delimiters on own, no l...

i'm java developer trying learn javascript ethos. are these 2 approaches creating static object in javascript different in non-syntactical way? approach more acceptable javascript programmer's perspective? approach a: var obj = {}; obj.field1 = /* expression */; obj.field2 = /* expression */; approach b: var obj = { field1: /* expression */, field2: /* expression */ }; i believe both of objects end being created in similar manner, , difference in performance (if any) minute point shouldn't notice difference. this not universal, though. when creating arrays, more efficient use similar approach b. because (at least v8) allocating array set size more efficient because knows size of array. // here v8 can see want 4-element array containing numbers: var = [1, 2, 3, 4]; // don't this: = []; // here v8 knows nothing array for(var = 1; <= 4; i++) { a.push(i); } source: smashing magazine i suggest trying out chrome profiling tools ...
