The IBM PS/1 (or IBM PS1)

The IBM PS/1 (or IBM PS1)

The IBM PS/1, sometimes called the IBM PS1, was a line of 1990s personal computer systems, not to be confused with the Sony Playstation video game console that’s also often called the PS1. The PS/1 was IBM’s second attempt at a mass market consumer PC, after the ill-fated PCjr.

You can neatly divide the PS/1 into two generations. While they ran the same software, they had major philosophical differences. Perhaps more than any other computer line, they represent IBM’s change of heart in the early 1990s as it tried to survive in an extremely competitive and crowded market.

Prong stuck in an outlet? Here’s the fix.

Prong stuck in an outlet? Here’s the fix.

The other day we went to unplug a lamp so we could plug a vacuum cleaner in. But something didn’t quite feel right. When we looked at the plug, we could see why. One of the prongs was missing. When we looked at the outlet, the prong was still there. The prong broke off in the outlet. There’s some bad, or at least time-wasting, advice out there on how to fix a prong stuck in an outlet or socket. Here’s how we fixed it.

Don’t try to work on an outlet without turning off the breaker first. If you’re patient, you can extract the broken prong stuck in an outlet with needle nose pliers and potentially avoid having to replace the whole outlet.

Computers in 1985: It was a very good year

Computers in 1985: It was a very good year

In some ways, 1985 was a really pivotal year for computing. The industry was changing fast, but in 1985, many relics from the past were still present even as we had an eye for the future. Here’s a look back at computers in 1985 and what made that year so interesting.

I think 1985 was interesting in and of itself, but it also made the succeeding years a lot more interesting. A surprising amount of the technology that first appeared in 1985 still has an impact today.

What happened to Digital Equipment Corporation?

What happened to Digital Equipment Corporation?

Digital Equipment Corporation was perhaps the second most important computer company in history, behind IBM. Its minicomputers challenged IBM, and, indeed, Unix first ran on a DEC PDP-7. DEC’s Alpha CPU was one of the few chips to make Intel nervous for its x86 line. It created the first really good Internet search engine. In a just and perfect world, DEC would still be dominating. Instead, it faded away in the 1990s. What happened to Digital Equipment Corporation, or DEC?

There’s a short answer and a long answer.

Vulnerability scanning best practices

As a vulnerability management professional, I talk about vulnerability scanning best practices a lot. There’s a lot more to vulnerability management than just scanning, but if you don’t get scanning right, the rest of the program suffers.

I’m going to talk about a lot of technical controls here, but don’t forget the nontechnical side. People and processes have to support all technology.

I get the question all the time how to take apart Hot Wheels without a drill. This trick doesn’t work on older cars with metal bases. But you can indeed take apart newer cars with plastic bases without drilling the rivet. The trick is to use a soldering iron to heat up the rivet and the plastic base enough to let you take it apart. So here’s how to open a Hot Wheels car with a soldering iron.
