These days, big inventions aren’t entirely new creations, but improvements on an old idea. This latest in a string of interesting science/technology breakthrough stories is about just that. Researchers at MIT (how many sentences have I started like that this week?) have developed a new way of constructing a capacitor. One of the limiting factors […]
How many times have I had this kind of phone call…. “my computers not working”… “the light on the monitor is on, but there aren’t any lights on the keyboard. everything seems connected, but there’s nothing on the screen.” Usually, my first question is along the lines of… “have you tried turning it off and […]

Yesterday I saw a machine that wasn’t booting. It would display the splash screen and then power down. They had a new […]
This is, in fact something I’ve been getting ready to do an article on soon. I had a system that had very strange and random problems that I’ve visited and tried many of the typical fixes for, in fact I think I saw it a couple times a week and either couldn’t reproduce the errors […]
