i've java(swing) application running on server , client(or assume 2 different computers),these 2 connected through internet not lan or wan..the client has send some data (around 200 kb) server.which method preferable transferring data..i used tcp through lan,but it's working slow through internet..so can use udp internet ? if yes, don't know how divide data chunks , send & again re-assemble data @ server. i thankful if source code provided udp transfer(bulk data in java). thanks in advance.. use tcp , want in way better can hope implement on own. if have low bandwidth, transfer in background or wait - there nothing can that. read data in byte arrays , write them whole - see datainputstream.readfully(). flush output @ end of writing. edit: if want send multiple images, 1 after other, can video compression - designed efficient @ that.

i'd calculate point on quadratic curve. use canvas element of html5. when use quadraticcurveto() function in javascript, have source point, target point , control point. how can calculate point on created quadratic curve @ let's t=0.5 "only" knowing 3 points? use quadratic bézier formula, found, instance, on wikipedia page bézier curves : in pseudo-code, that's t = 0.5; // given example value x = (1 - t) * (1 - t) * p[0].x + 2 * (1 - t) * t * p[1].x + t * t * p[2].x; y = (1 - t) * (1 - t) * p[0].y + 2 * (1 - t) * t * p[1].y + t * t * p[2].y; p[0] start point, p[1] control point, , p[2] end point. t parameter, goes 0 1.

is possible use multiquery , have 2 hql queries returning 2 different sets of entities 1 of sets used in other , session "fixes" via first level cache? e.g. scenario (a dumb 1 , solved joins) public class room { ... public virtual iset<bookings> bookings {get;set;} public virtual bool isavailible {get;set;} ... } public class booking { ... } after executing multicriteria 2 hql's: returning rooms isavailible = true returning bookings having room has room isavailible when accessing room result , bookings want them resolved second resultset via firstlevel cache of session , there avoiding n+1. generally speaking, nhibernate can use cache "combine" results queries executed through multiquery. however, should noted applies cases lazy collections loaded no restrictions whatsoever. examples: invoice ialias = null; invoicedetails idalias = null; // base-query: invoices condition var invoices = session.queryover<invoice...
