i have develop client/server game uses lot of network request complete task. both client , server receive multiple command through socket. handle these commands created networkhandler class listens new input on separate thread , allow me send new commands. these "commands" heterogeneous , and used different classes.

(all through interfaces ) the problem every class wants register "command receiver" need call commanddispatcher set listener. because there multiple class needs reference i'm thinking transform commanddispatcher in singleton class accessed everywhere. i know singleton , global class bad , i'm hiding dependency , difficult test, alternative see passing commanddispatcher mai...

i git-beginner, apologies naive question: i turning local repo mess doing following: changing things , committing them not pushing. repository on server has been changed other users. ideally want ignore commits, pull last version server, , commit change , push. there way of doing this? assuming master branch involved, this: $ git pull --rebase origin master you pull changes master branch, commits rebased if had first pulled new changes, , then, started making changes , committed. you can just $ git pull but you'll end merge commit. rebase first (or pull --rebase ) keep history easier read. check out these git tutorials: https://www.atlassian.com/git/
