According to the NYT, quantum computers, still in their early development, have reached the ten qubit milestone. To give you some perspective, a forty qubit quantum computer can perform ten trillion calculations, ten teraops, simultaneously. Forty atoms sitting in a nuclear magnetic resonance rig can rival the power of the largest supercomputers. A thousand atoms would solve problems currently considered intractable by conventional machines.
I’m still a little fuzzy on the theory behind quantum computers, and I consider myself very well informed, but I found this page that demystified things a bit.
Some folks–well, one at any rate–have expressed surprise that I don’t have more links and rants about nanotechnology on my site. So to address that issue:
Just to give a little perspective, I first heard about nano back in 1987 when a friend told me about it. I read Engines of Creation in 1988. In other words, it’s old hat to me. That’s probably why I haven’t gone nuts and plastered my site with nano stuff. To me it’s a foregone conclusion–nano is coming and the world will change beyond recognition. That’s both good and bad.
You know those wireless gadgets with the little thumb keyboards that people use to send e-mail and chat with? I’ve decided to call those “mbiras.” An mbira is an African musical instrument, most commonly found in Zimbabwe, that is held in the hands and plucked with the thumbs. Seeing a friend use one these things reminded me of an mbira player so the name stuck in my mind.
Please feel free to use my coinage.
Gödel proved that mathematics will remain forever incomplete.
The implication is that the mathematics is infinitely rich. Another implication is that all science, being ultimately based on mathematics and logic, is infinitely rich and will never be a finished thing.

In my endeavor to make this site a useful place for web developers to visit, I offer some obscure information about the
accesskey attribute in XHTML and HTML 4. As I gather more information, I will add to this entry. I may even move it to my developer section.

Extra power to Jake and Jeff–two well known guys who battle daily for honesty on the Web. But more power still to Vince, one of the oft forgetten pioneers for good Web design. Besides he’s much funnier than the other two.
I’ve set things so that I have a customized icon if people decide to add this site there favorites list in IE 5+. I don’t think this will work in IE 5 for the Mac but, let me know if it does. What’s a customized favorites icon?
Added (June 12th, 2001): I’ve discovered that this icon idea also works if a visitor bookmarks my site in Konqueror too. So the trick is becoming more cross-platform.
There is also free Java tool that can help you design and build your icons for your sites.
This is all Microsoft’s fault. IE 3 had terrible implementation of CSS and could only support absolute font units like point (pt). Legions of web designers quickly began cranking out zillions of pages that were, and sometimes still are, damn near impossible to read. Here it is nearly 5 years later and the Web is still suffering from this.
I promise never to do that here. Geezers like me need things to be ergonomic, right?
