J.A. Watson

I started working with what we called "analog computers" in aircraft maintenance with the United States Air Force in 1970. After finishing military service and returning to university, I was introduced to microprocessors and machine language programming on Intel 4040 processors. After that I also worked on, operated and programmed Digital Equipment Corporation PDP-8, PDP-11 (/45 and /70) and VAX minicomputers. I was involved with the first wave of Unix-based microcomputers, in the early '80s. I have been working in software development, operation, installation and support since then.

Laptop Review - Fujitsu Lifebook S6510

I have been using this new laptop for about a week now, and I am very pleased with it. There have been a couple of minor irritants, as is always the case with a new computer, but overall I don't think it could have been much better.

The Gizmo Project

The Gizmo Project

Next on my list for evaluation is The Gizmo Project. Gizmo actually comes in two (well, three) varieties - a text and audio only client (no video) for Windows, Mac and Linux; a text/audio/video client that is still in beta test, only for Windows, and a version for mobile devices that runs on various internet-enabled smart phones.

Tech Talk - A Peek Behind the Curtain

Tech Talk - A Peek Behind the Curtain

I've spent a lot of time discussing video quality, resolution, frame rate, bandwidth and the like. But after using this information to set the video resolution, or optimize your setup to get the best possible performance, how are you going to know if it actually worked?

Tech Talk - Video IM Tips and Tricks

As usual with my "Tech Talk", this will be a somewhat more technically detailed description of some things to do, to avoid, or to simply keep in mind to avoid problems or to find them when they arise. This one is going to concentrate on hardware, and the next will be about software.

Addendum to the Comparison

Addendum to the Comparison

I have received a very friendly reminder from ooVoo that their System Requirements say "Broadband connection (Cable, DSL etc..)", and I think it is only fair to repeat that again - I don't want it to sound like I am faulting them for marginal performance in an environment that they don't even claim to work in!

Video IM - Tips, Tricks and Preparation

Video IM - Tips, Tricks and Preparation

I am frequently asked for advice about hardware, software and connections for Video IM. I suppose this is a bit like putting the cart before the horse, since I have already written quite a lot about the major Video IM programs, but better late than never...
