i've spent better part of 2 days on this, , things keep getting broken. started when added couple environment variables .zshrc file, , installations of rails stopped working, after removed env variables. rails getting confused find gems? ruby: 1.8.7 rails: 2.3.16 database adapter: mysql update think i've solved it. case of missing gems required (not sure ones exactly) took care of both rail. issue required letter_opener gem, required me use specific_install (0.2.3, not 0.3.3, looks uses different ruby).

i new f# maybe solution can clear someone, can not find it. imagine game world of world chunks (similar minecraft), more players. in theory language c++, java, or c# can modify multiple chunks of world @ same time. 2 or more players try place or remove block in different chunks , these actions can change state of world without affecting each other long no more 1 action in each chunk happening. serializing happen when multiple players in 1 chunk perform modification. my understanding of f# need serialize these actions on global level , no 2 actions can happen in same time in entire world, because update function need actual world state update params(like add/remove blok) , return new world state . example world state contains chunk list . is there way world update in parallel? can world state stored differently allow update multiple chunks @ same time? it sounds need ensure each chunk has 1 action run @ time. can protect pieces of state storing them inside mai...
