I installed Apache, PHP, MySQL, and Mediawiki on my MacBookPro laptop, on the PC side. I’m not sure what good it does to have a wiki on it, but at least it will give me a chance to learn what you can do to administer a wiki. Don’t come looking for it; it’s not on RollingOnOne, just my home machine. But that’s more serious software than I’ve much had on that computer, after having it for almost a year.
