Nearly every car can reach 3Gs without a problem - just apply the brakes.

Here are some guys doing actual measurements on hi-end Porsches. Less than 1.5G's tops.

On titanium rings:

They're not practical for any purpose other than being a wedding ring, and do you honestly need any more purpose? If I ever have need of one, I'm definitely going with the sine wave style.

Dan Statman (of the site you linked) is a member of the TurboCNC community, CNC software that runs on an old 486 with step rates up to 20,000Hz. TurboCNC is being actively developed by Dave Kowalczyk. It's 100% free to use, $20 for the Pascal source. This is for something that can cost hundreds or thousands of dollars elsewhere, and would never run on anything below 400MHz.

Dan Statman built all of his own tools, using TurboCNC to drive his titanium-ring engraver. He quit his job and does this full-time now. He's a regular poster (as am I) in the TurboCNC user group.

It's amazing what you can do with $300 of scrap metal and surplus parts.

My wedding ring is pretty geeky -- it's titanium with engraving -- dots and vertical lines representing 0's and 1's, which spell out my wife's initials in binary (in 5-bit letters). I got it here; the guy that runs the place is very open into making custom-made designs.

I had thought about actually using it for something, like an encryption key -- for example if I started at a certain place on the ring, went a certain direction and counted up 7 or 8 bit ascii words, I could get a passphrase after a while, a pretty strong one. At this point all I would need to memorize for a theoretically very long passphrase would be the starting location, direction, and number of letters.

Even if the men in black kidnapped me and found my ring, they would still have a hard time figuring it out ;-) Now only if I could find a titanium hat -- the tin ones are so 20th century.

Hey, check out RennList for an active community of Porsche owners.

To be on topic, some stuff (kernel mods) are specificly written for that kernel version, and you don't have the resources to upgrade to newer hardware (or perhaps there isn't newer hardware).

I inscribed my wife's initials into it as binary. Just a lot of silver-inscribed dots and lines, no one knows it's binary unless I tell them, and then it's a lot of "umm, ok..."

No not ascii, there wasn't enough room for 7 or 8 bits each. 5 bits, for 15 dots/dashes. Got my ring from this site (of COURSE I ordered it through the web ;)
