It has to be a pretty big rock to be hot when it hits the ground. Smaller pieces, on landing, are often found to be quite cold, entry heating not being long enough to remove the in-space cold soak, and the upper atmosphere being chilly.

That would make sense; it's clearly a fragment from a larger object that broke up during entry, probably late in the heating phase. (There is a visible dark "outside" and light "inside" on the piece we see.) So ther

Well, it's certainly not an exact copy of the old website; I remember that it had ASCII art of the "mascot" in the source. This one doesn't. Which is an odd difference; the new "owners" appear to be a little le

Saving printing pigments (ink/toner/latex/whatever) makes more sense as printing systems get more "professional". It's almost useless on a cartridge-based inkjet printer, because those generally track something

MtGox has never provided a good reason why they were missing so much in various asset classes. They tried to point to "transaction malleability" early on, but people who have traced such activity say that it can account for only a

Rack space is an ongoing cost while the hardware is a fixed cost. Presumably they've decided it's worth having a slightly higher fixed cost per GB in exchange for a reduced ongoing cost per GB. (There's probably other benefit

Prices are the result of supply vs demand on the exchange market; total supply is a secondary factor. Multipool miners will generally sell for BTC/fiat immediately, creating lots of supply and thus a consistent downward pressure on pri

That sealed it for me, too. Satoshi and Dorian Nakamoto write like completely different people--so different that it's an unbelievably good false flag operation otherwise. Futhermore, Satoshi's style is appropriate to the demogra

The demographics have changed around the first- and second-generation malls enough that many of them are no longer viable. Since they're huge properties, they tend to rot slowly. They're finally dying. There's probably some f

Apparently what Tesla was initially told when NJ "discovered" a problem with their not-entirely-clear dealership law was that they would allow Tesla to keep selling until the legislature had a chance to clarify the issue. Recently

22 minutes is quite good. 7 is about normal. Even on the larger ones, you don't often see >10 min. Actually, the Phantom 2 is said to go 25-30 minutes, but perhaps that's without payload. This fellow went all-out to get 97 minu

A court could simply order them frozen, and expect the holder to comply. If the court deems that too dangerous, they would order them transferred to a third party guardian (usually the local sheriff or similar, but they might make a differe

The FAA usual procedure is "prove to us that it's safe". You can point to other certified craft using the same or similar technologies or systems, and say "it works there, so we'll be okay". This is what most o

I thought I saw those too, but haven't been able to find them in the FAA notices for model aircraft. There is such a clause in the 2012 for small unmanned aircraft (sUAS) use by a "government public safety agency". I would pr

That may be useful then. I don't think there's any specific rule against a fully-autonomous system, though it would certainly raise some eyebrows. If you do it with enough safeguards and in a safe area, you might get away with it.

UAVs (UASs) can operate above 400 ft with a Certificate of Airworthiness (or similar.) However, the FAA will not yet issue you one, as they don't yet have to rules to do so. UAVs that qualify as "model aircraft" can operate i

Unless you're collecting your data under 400 feet, this ruling isn't going to enable such a system. Only "model aircraft" operation is involved.

It's not quite so big as the headline, but it's still good. Here's the scoop: The FAA has long had rules for model aircraft, which would include many small "drones", and under which you can personally operate them n
