We'll stop using the comma when you stop celebrating the bombing of the world trade centre November 9/11/2001 instead of September when it actually happened.

I think there are some folks on a small island off the coast of France who don't use the comma as a decimal separator and who label 2001-09-11 as 11/9/2001.

(But I suspect some folks in Europe might not consider the folks from that island Europeans.)

Comment Re:Remember the NASA Wind Turbines? (Score 1) 179

Current blades are trucked in one piece (per blade) which is impressive to see. Three of them were parked on I-5 outside of Patterson, California a few months ago. There are a lot of net videos and photos which convey the scale.

Even at the current size they can't get through many highway interchanges and local intersections. The larger ones won't be able to ship in one piece at all.

NASA Wind Turbines approached this scale in the '80's. Unfortunately, this was a previously-unexplored area of aerodynamics for NASA, and they had mechanical stress and noise problems (including subsonics) and were all demolished. I think there was one near Vallejo, CA being taken down when I got to Pixar in '87, and one in Boone, NC, which famously rattled windows and doors.

The art has since improved. I took a ride to the top of the turbine at Grouse Mountain, that was fun! That's the only one I have heard of where you can actually get to see it from the top.

Comment Starting out with the wrong assumptions (Score 2) 165

This is starting out with the wrong assumptions.

Design a brick system that can be produced with 3-D printers, and will hold together when fabricated within the tolerances of an SLA printer. Forget FDM, it's too low precision and SLA is already achieving an equal or lower cost of manufacture compared with FDM.

LEGO is manufactured to astonishingly high precision, but I am not convinced that this is the only way to make a brick system.

Blue Origin will eventually have a two-stage rocket that can reach orbit (although they are planning on a much smaller payload than SpaceX for their first iteration). When the booster of that rocket lands without damage, they will duplicate what SpaceX has recently done, although in smaller scale.

Blue Origin to SpaceX at present is a sort of bicycle-to-automobile comparison if you account for the tremendous difference in energy and the application. So, I think there really is an intrinsic difference between the two of them.

If you want to say there's no intrinsic difference, then we need to look at Orbital's Stargazer and Pegasus, which have been carrying small payloads to orbit for years, and there's only been one Stargazer all of that time so there is no question that it's reusable. The only difference is that Stargazer lands horizontally.

We can then look at the B-52 and X-15 combination, in which both stages were reusable, a human was the payload, and we're going back to the late 1950's.

Or, rather, where you have to go through an annoying procedure, involving two reboots, to write to /usr or /bin.

If you think that's annoying, you should try working with SELinux some time.

I haven't tried actually working with it, but I've certainly been annoyed when it kept VMware's hgfs from working on Linux guests - it wasn't immediately obvious how to let it work. (I think my VMs running newer versions of Fedora don't have a problem with hgfs, so maybe either VMware or the SELinux people fixed it.)

PiS admires the Russian form of a 'strong government'. While it doesn't try to implement a carbon copy of it, PiS borrows some 'bright' ideas from both the Russian and Hungarian systems (nationalism, 'strong leader' with much power, mythical 'they' who are always to blame for the failures, etc.).

Ideas that were also present, at one point, in a certain country to the west of Poland that eventually went to war with the Soviet Union (after signing a deal with the Soviet Union to carve up Poland), so it's not as if this behavior is obviously "soviet" or "pro-Russian".

Although Anonymous Howard up there might be using "soviet" and "Stasi" just to mean "authoritarian", not to mean anything necessarily having to do with Soviet-style Communism, as per

Was there anything suspicious in the billions of UK communications that GCHQ has intercepted? Yet the government hid the mass surveillance from Parliament and everyone elected has been subject to this surveillance and the manipulation that goes with it, meaning we get nothing but pro-Stasi governments in the UK.

so they could just as easily have said "Nazi" and "Gestapo".
