| + | {{gtspring2009:gibson.png?24}} Re google code: maybe. I want/plan to move channelflow svn from the GT physics dept, so that it can be seen by the world. Maybe putting it on google code would be good, the whole channelflow website, less likely. The main benefit of channelflow.org is easily-editable pages via dokuwiki. My experience with massive code-hosting sites (freshmeat.net, gnu's savannah.org) is that they're totally inflexible (e.g. probably no dokuwiki), and that not having shell access makes administration a major pain. But I will check it out. | ||
| + | //Twenty minutes later// Hmmm, there is almost no documentation available for code.google.com, nothing that explains what features are support, how much disk space is allowed, etc. Just "click here to host my project". 2009-05-04. | ||
