Love it! We need a site dedicated to this kind of thing - assortments of various bits of hard to find knowledge that come up when you're learning about a new platform/language/framework/(anything?). IMO, the learning curve for say, a new framework is often dominated by this kind of knowledge - not particularly complicated, but hard to find when you don't know what you should be looking for. The problem of course, is that when you really dive in, there are FAR too many of these kinds of tips to be useful on a single page. Maybe a sophisticated search or categorization that would let you loosely specify the symptoms of a problem, or what you want to accomplish in simple words would work. Also, some way of specifying your level of knowledge in each area that the problem involves would be nice. So for example, if you selected proficient with UNIX then it might say "install these libs from source with x flags", and lower levels might have more info about how to deal with problems that crop up during that process.
