Someone sent my a large patch for SWARM (my low level ARM simulator written in He's done some good work adding a UART and LCD controller to SWARM and is apparently working on port uCLinux to SWARM. Unfortunately I discovered the down side of being a project manager - having to send code back as I found it didn't work properly. I'd love to put this guy's work in, and feel guilty about having to complain as he's done all thei wonderful stuff, but if I accept something that hasn't been tested properly into the tree then it looks bad on other that have pitched in. Hopefully the guy won't be too peeved and will send me a checked version so I can release the enhanced version.
On a similar topic I discovered VTWM is being maintained, and am now discussing my patches with the maintainer :)
