- Shaw's opening volley: http://web.archive.org/web/20080103072111/http://www.zedshaw... [lots of stupid personal flames - but his technical points are consistent with what I remember from the time]
- DHH's response: http://david.heinemeierhansson.com/posts/31-myth-2-rails-is-...
- I can't find a copy of shaw's actual response, but here's the relevant HN thread: http://news.ycombinator.com/item?id=364659
The salient point (quoting Zed):
Now, DHH tells me that he’s got 400 restarts a mother fucking day. That’s 1 restart about ever 4 minutes bitches. These restarts went away after I exposed bugs in the GC and Threads which Mentalguy fixed with fastthread (like a Ninja, Mentalguy is awesome).
If anyone had known Rails was that unstable they would have laughed in his face. Think about it further, this means that the creator of Rails in his flagship products could not keep them running for longer than 4 minutes on average.
Repeat that to yourself. “He couldn’t keep his own servers running for longer than 4 minutes on average.”
I've never been much of Ruby/Rails guy - but my understanding is that everyone had to restart Rails a few times an hour cause the memory leaks were so bad in those days.
Zed's rant/flame goes into so much personal detail that he doesn't really articulate the point. Rails was receiving this enormous amount of hype, but there wasn't even a working application server yet.
