I've been involved in an interesting discussion about enabling (or not) ssh on production machines, starting here.
OK, yeah, I get it, it's an anti-pattern. Something to avoid. I'm 100% on board with that. On the other hand, whether or not you can/should make an absolute prohibition depends a lot on what kind of system . . .
In the context of the news that the Linux kernel finally getting rid of variable-length arrays, I figure I should finally write about one of the more difficult bugs I've worked on over the last three decades.
This one was at Revivio, where I worked from 2002 to 2006. We started having these problems with machines sporadically hanging. . . .
