Comment Re:Remember the NASA Wind Turbines? (Score 1) 178

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.

Comment Remember the NASA Wind Turbines? (Score 4, Interesting) 178

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.

Comment Re:No comparison (Score 1) 132

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.

Actually no, the ME is off as far as user facing features are concerned, but if it is fully off, good luck booting your PC. The MS is always on, and contrary to Intel's public stance, when you buy a SKU with it disabled/no BIOS for it loaded/fused off (depending on whom you talk to, I have gotten all three many times), it is still there, still functional, and still not under your control.

In short 'off' means the user facing and user accessible parts are no longer user accessible, not what most people still consider off. Intel refuses to talk about or publicly document what features are there and what are still active in each of these modes. I have asked them for this information and they said no. I have been digging on the ME for literally years, and have a fair idea of what it can do and can't do in both states.

And I am scared sh*tless by what I found.

This is done in the US with all printers, copiers, and just about anything else that can produce digital output. They are all watermarked with the printer info, time and date, plus likely other stuff encoded in (usually) yellow dots all over the page. The EFF had a decryption project for it, not sure how it ended up but the landing page is here:

Comment Re:Deduplication anyone (Score 1) 284

Dedupe is usually done at a block level, no a file level for this specific reason. Encryption, compression, and the like will cause headaches for the hypothetical one byte changes, but that is probably a solved problem by now. I have not kept up with the minutia of dedupe lately but for an outfit the size of Google, it would probably be worth it to decompress the files for dedupe. No clue if they do though, but it is not a huge technical challenge.
