I am far from an expert, but there are two ways I know of to do something like variable compression, one is that Saab technique already mentioned, where the cylinder head is displaced to change the size of the combustion chamber. The other

I gave this to my colleagues when I joined the my current development project, the lessons about trying to scale development teams remain pretty sound.

This is huge, and if you're interested in an issue, these days it's often not all that difficult. The conceit that you can "get informed" by just reading current news is just plain false, and probably has been for as lon

The very first sentence of this article is a giant red flag, the comparison between the Pantheon in Rome and modern concrete is deeply misleading -- Roman concrete was a different material than modern Portland-cement/sand/gravel s

Maybe on average the price didn't change, but in the "no-tipping" case, customers can no longer self-select into their various price points. What businesses actually want out of their pricing model is to have a bunch of peopl

Several years ago, I read Erik Conway's "High Speed Dreams", and learned about an important feedback loop that operates in the SST world. What happens is, you design an SST, figure out the noise profile, and are horrified. Yo

I agree in general, and it would have been nice to see some plots of some of quantities that should be conserved, e.g. how well does his simulation preserve the initial energy and angular momentum? Having said that, it is an adaptive RK sch

The article says they set new distance and duration records, at 7000 miles and 137 hrs respectively, but the Breitling Orbiter 3 did a 25000 mile track in over 19 days in 1999. So what's the right scope for this record? Their end-poin

I think this would be a useful conversation. The userlands are pretty similar, I think, they both support the GNU tools, as is attested to by the existence of Debian/kFreeBSD. I don't know what the OP's motivation is, but I&#
