angry at gunzip; Why can't systems be a bit more reflective?

argh! I'm getting angry at gunzip. Why is there no default "just decompress"?

Why doesn't my shell detect that I'm having a common problem, and send me a link to the solution? It should be easy to set up a Google search. It shouldn't be too hard to make a collection of common error messages, and troubleshooting pages for them.

Why can't systems be a bit more reflective? (this applies even more to the streak-marks problem I wrote about before, and also to processes that never give up, leaving your machine hanging... do they need to internalize the notion of user utility?)

weird email behavior

There's a lot of weird email behavior out there that I don't understand.

Why do you sometimes receive a message through a mailing list where the mailing list's address doesn't show up in the "To" or "CC" headers, but only in the Reply-To? Are these people BCC'ing to the mailing list just to fool my mail filters?

(Not to mention that putting the list's address in the Reply-To will cause "Reply" to reply to all... confusing the poor souls who made absolutely certain that they wouldn't click on "Reply All")
