The tool should work efficiently without you ever looking at the settings, but if you need it you should be able to change anything you like.
Not sure it applies to consumer interfaces. Ideally it shouldn't. But for tools that you use to do day-to-day work, absolutely.
Your dad needs to see a counselor to help treat the alcoholism and a therapist to try to eliminate any underlying psychological issues that might be feeding into the alcoholism if there are any.
My uncle died of essentially alcoholism.
You have the right to tell your dad, dead in the eye, that you fear for his life and that he does not have to continue this downward spiral. He will need to summon a will in order to beat it, though. It might help to also remove him from the environments that contribute to his problem, such as moving to a dry town.
It still amazes me that I used to drink more (was always moderate) but really tapered off lately for multiple reasons (most related to health) without much difficulty at all, yet some people get completely addicted to this thing. (I have nearly all German and Czech ancestry which might help.) Yet there is a game called WoW that I can't seem to tear myself completely away from, and there is a woman on this planet that is impossible for me to not have amazing sex with when alone (she shares the same vulnerability) who I unfortunately cannot be anywhere near anymore because we are not right for each other and must focus on other people...
Careful now :) It's not like there's anything stopping HN attracting a wider audience anyway; there's no restriction on who can register. Anyone can come and join in, which (in my opinion) is as it should be.
I would expect it to solve most of your performance problems for the foreseeable future (at the very least, by letting you scale horizontally and move the DB, frontends, and memcaches to separate boxes - plus ending memory leaks/etc by moving most of the data off the MzScheme heap).
The obvious downside is that it would use your (or someone at YC's) time. First to merge the changes I make to http://ycombinator.com/arc/arc3.tar into the production code, then to buy/setup some extra boxes and do the migration. We're probably talking, roughly, a day. It also has the unfortunate side effect of costing HN's src some of its pedagogical value, since it adds external dependencies and loses 'purity'.
Been looking for an excuse to learn arc for a while now ...
The site is very much hacked together, but works... In a lot of ways, this reflects the hacker ethos of getting something up and running quickly at low cost while still producing value.
A revamp might have negative impact too by attracting a wider, more mainstream audience which could possibly dilute the purity of the community here.
