why extension methods require declaring class static? compiler requirement? it's dictated in language specification, section 10.6.9 of c# 4 spec: when first parameter of method includes modifier, method said extension method. extension methods can declared in non-generic, non-nested static classes. first parameter of extension method can have no modifiers other this, , parameter type cannot pointer type. it's not clear me why all of these restrictions necessary - other potentially compiler (and language spec) simplicity. can see why makes sense restrict non-generic types, can't see why have non-nested , static. suspect makes lookup rules considerably simpler if don't have worry types contained within current type etc, dare possible. i suspect complexity of not having these restrictions deemed less benefit gained. edit: clear, i'm not suggesting make sense have instance methods extension methods - i'm suggesting make se...

i'm wondering if should save data in app plist or using core data.. my app saving tweets timeline , other users now. less few hunderd kb (about 200 kb in testing). what's advantages of using core data? i not consider plists other saving simple preferences , basic data structure. plus performance wise, retrieving , saving data plists can quite slow. after struggling coredata long time, choose on day. yes have bit of steep learning curve there "for free" it, i'd invest time learn , explore it. coredata give flexibility expand object models needed, fetch objects persistant storage based on parameters, create relationships between models, memory management , list goes on. coredata documented apple find need started plus more. there examples, sample projects, videos, name - i'd definitly recommend have if interested in performance, scalability , having bit of fun :)

so i'm using following: $r = new record(); $r->select('ip, count(*) ipcount'); $r->group_by('ip'); $r->order_by('ipcount', 'desc'); $r->limit(5); $r->get(); foreach($r->all $record) { echo($record->ip."

am curious why modern browsers allow switching off javascript. it's clear substantial modern web application need integrate high level of javascript, why cant javascript made integral part of browser? becomes more annoying when option off default (ie!!) my opinion is, should made standard browsers have javascript option enabled default. what guys think? i'm sure you're venting here, being able turn off javascript thing many reasons both developer , otherwise: makes easier debug problems html , css helps lot of privacy issues can avoid malware , other security issues speeds browser, reduces memory leaks, etc also, fwiw, there no browser ships default of javascript being off, ie included. perhaps you're dealing corporate installation customized defaults?
