  • DIY Signboard

    Web server outages suck. Let’s celebrate the Blahg’s return with a DIY LED project – signboard 2.

    Do you keep your system in tip-top shape all the time?  Do you clean up old, unneeded files, wipe down the case, clear our the dust, and perform regular backups?  If you’re like the vast majority of home computer users, the answer is no.  I’m certainly not one who is good about doing these things.  […]

  • Set your USB key up to auto-run on insertion

    I’ve known this was possible for a while, but I hadn’t looked for nor stumbled upon instructions for putting an autorun file on a USB key and getting it to work.

    Thankfully, there are more people out there that feel as I do about some of the so-called “security” we are getting for our tax dollars.  And they are way smarter than I am, so they write insightful things about the problem.  So there are frequently new posts out there from which I can draw.  The […]

  • Do it yourself air conditioning zone controls
