when i'm writing method or using member variable, find need share them across app. should go? i can subclass activity, falls on use mapview , forced use mapactivity, not activities inherit subclass. there way around this? where inheritance isn't applicable, tending put generic methods , member variables subclass of application object, i'm finding it's creating mess of code every class needs either grab access application object through via context, or have pass down. i suspect better off creating myapplication.getinstance() , keeping in singleton, instead of passing application object down through app classes. before wanted see guys had say. if want access "global singleton" outside of activity , don't want pass context through involved objects obtain singleton, can define, described, static attribute in application class, holds reference itself. initialize attribute in oncreate() method. for example: public class applicationcontro...

i watching video on node.js , saw speaker say, prefers instead of using anonymous call backs: var server = server.createserver(server.createreq(req,res)); i think nice named function parameters can passed instead of anonymous function closure. question 1: implementation of createreq returns anonymous function, wouldn't it? how better? can see being better because unlike closure @ createserver level, closure @ createreq level more contained - not store reference other unnecessary variables (non req,res). and speaker said, guess visualize realtionships better between different parts of code. question 2: there other benefits? a reason why might want call function returns function may starting multiple servers within same process, , want them share same request handler. another thing keep in mind each anonymous function must allocated on heap, , incurs garbage collection overhead. using named function instead of anonymous function, can reduce cost. for...

is there method calculate general "similarity score" of string? in way not comparing 2 strings rather number (hash) each string can later tell me 2 strings or not similar. 2 similar strings should have similar (close) hashes. let's consider these strings , scores example: hello world 1000 hello world! 1010 hello earth 1125 foo bar 3250 foobarbar 3750 foo bar! 3300 foo world! 2350 you can see hello world! , hello world similar , scores close each other. this way, finding similar strings given string done subtracting given strings score other scores , sorting absolute value. i believe you're looking called locality sensitive hash . whereas hash algorithms designed such small variations in input cause large changes in output, these hashes attempt opposite: small changes in input generate proportionally small changes in output. as oth...
