cocoa - Feasible to switch to objective-c on these platforms and situation? -


i've written of game engine using c++ runs on osx , ios (xcode 3.5 so, gcc), linux (gcc), , windows (vis studio 2010). uses stl vector collections of objects. implements message passing. engine using opengl on ios platform , use opengl on platforms , potentially directx on windows.

i don't c++, although have strong understanding of it. i'm c programmer , after introduction objective-c year ago, realized it's ideal how work , think. huge advantage me switch objective-c. unfortunately, beautiful world of osx/cocoa isn't reality of windows or linux.. or it?

i sure cocoa/apple/next evangelist provide me masterpiece of answer here

edit:

looks cocotron , gnustep 2 options, gnustep being more mature seeming have more baggage such requiring runtime.

i need solution can fit these requirements:

  • able compile, run, debug objective-c on platforms
  • able use cocoa api calls on platforms (ie nsstring, nsnumber..)
  • endusers should able install , run app without installing extra, or @ minimum installer should able , non-pervasively install (such runtime) gnustep requires runtime, cocotron not
  • explains issues may hit. example, able use provided cocoa stuff parsing xml? cfsocket? cg? solution end , go in realm of os-specific libraries aren't ported?

ideal:

  • can support closures (blocks) on platforms can use gcd , libdispatch becomes available, if boils down less efficient situation on non-native platforms
  • an api allow core data type data management (i'm dreaming here), if boils down less efficient situation on non-native platforms
  • a forward-looking solution maybe use llvm since seems way things moving

do not require:

  • gui functionality such drawing nsview etc
  • ide functionality except on osx
  • objective-c 2.0
  • objective-c++
  • garbage collection
  • ease of my setup: is, it's ok if pain me set , configure working, long working solution fits needs , allows me write code easy (portable per requirements above) , doesn't push of pain on users.

cocotron absolutely phenomenal software has suited every need far. while documentation poor , it's hard understand , working, it's extremely worthwhile , awesome.

the llvm/blocks/libdispatch doesn't seem quite reality yet, although may be, think @ switch xcode 4 real. boils down mingw working llvm.

there implementation of core data.. wow

php - How can I stop spam on my custom forum/blog? -

so have custom built forum & blog system of late has been dealing lot of spam. if wordpress use akismet, if different common platform i'm sure i'd find plugin. there kind of static class can download this? using php. i'd still go akismet, if it. uses outside of wordpress, may have pay fee it, depending on use -- check terms , conditions -- it's option , easy implement in php using api. use api key wordpress. com account access. basically, grab whichever php client library takes fancy -- use alex potsides' php5 library -- plug in key, , it's handful of lines of code. here's bare bones of validation straight 1 of live sites: ... if ($akismet) { $akismet->setcommentauthor($name); $akismet->setcommentauthoremail($session->userinfo["email"]); $akismet->setcommentauthorurl(""); $akismet->setcommentcontent($sentence);...
