OK, I've written on both of these topics before, and nothing has happened for months, so I'm writing here.
First, Debian's list archives will most likely die a horrible death on January 1, 2000. That's right, folks; lists-archives is not year-2000 compliant. Not only will dates in indexes appear wrong, but after some testing yesterday, I believe the whole thing will blow up. I have fixed my private lists-archives to have such compliance (I've also fixed a lot of other bugs in it), but nobody has been interested in the patches, so... Secondly, whenever you search for something in the mailinglist archives on www.debian.org, you get back a page of results. Click on any result, and you get a 404 error. This has been broken for literally months; I reported it a long time back, have prodded people since then, and nothing has been done. Can somebody with the power please fix this?
