The end of the Microsoft Flight Simulator

I’m pretty late in noticing this, but the Microsoft Flight Simulator is no more. Microsoft shut down ACES Studio, the internal group that developed Microsoft Flight Simulator, back in January 2009.

I think this is a shame because the Flight Simulator was one of the oldest personal computer programs still being actively developed. Although some sources (including Microsoft) state that the first version was for the IBM PC in 1982, the program actually dates back further than that.

DIY Nuclear Fusion

Here’s an article from the Wall Street Journal with a startling title: Nuclear Ambitions: Amateur Scientists Get a Reaction From Fusion. It focuses on amateur researchers who have built their own fusion reactors.

Their fusion reactors, or fusors, aren’t used for power generation. That’s because a fusor consumes more energy than it produces. Fusors have been used commercially as neutron sources, but the interest among these researchers seems to be improving the device itself.

Rechargeable Batteries

I’ve used rechargeable batteries for many years, mostly nickel-cadmium batteries, also known as nicads, which are ideal for infrequently used items such as radios or flashlights. They can be stored safely and they don’t lose their charge over time. Even though nickel-cadmium batteries can last far longer than most people think, they do eventually wear out and need to be replaced.

When I recently tried to buy some replacement nickel-cadmium batteries, I was surprised that I couldn’t find them anywhere. Nickel-cadmium batteries must have gone out of favor while I wasn’t paying attention. Environmental concerns may have played a role because cadmium is a heavy metal and difficult to dispose of safely.
