To improve the infrastructure, one should feel strong about areas he
want to improve. I do infrastructual work in areas, where I think I've a
clue. Asking me to work on schedulers or SMP architecture where I don't
feel competent enough is just unfair, John. The time I need to spend on
educating myself in those areas will be much longer than I can afford.
So my choice is leave broken code and ignore the users, or fix it using
tools available now and fix it better when the infrastructure is ready
or I've time to work on the infrastructure in this area.
If someone competent will provide infrastructural improvements I can
use, I'd love to use it. I try hard not to leave my code behind.
Can we move on now?
