Comment 3rd link error (Score 1) 4

Your 3rd link is a duplicate of your second link.

I've never understood how people can lose their Slashdot IDs. Don't they, like understand how to keep offline backups of passwords? I mean, that's a pretty "had your geek card in" error.

I'd have to check dates, but I remember a friend (with an early broadband connection - at around 1000£/ month) telling me about it, so I signed up on dial-up. Learned to open multiple tabs, drop the connection (well, phone calls are metered by the second here) while composing replies, then re-connecting before posting them. Not as good as USENET, but worth the effort.

It is getting crappier and less interesting though. It's often a week or 10 days between my visits.

Unsurprisingly, not 3d-UIDs so far.

Yeah, but you're not everyone.

I don't know how organised natural history fans are in Iceland, but I know who I'd phone if I found a winged insect that I couldn't positively identify myself (which is most of them) and which I thought might be an invasive species (which I wouldn't really consider, since we already have several tens of species of mosquitoes, and many other genera of biting and non-biting flies). Most counties have a network of "recorders" responsible for collating reports of novel organisms, of organisms found in places where they hadn't been previously seen (how do you think the human-assisted spread of beavers has come to formal notice) and - for larger organisms, they also keep count of roadkill reports, which is a useful contribution to estimating wild populations.

There are plenty of good reasons for people with a natural history interest to keep track of novel (and "unrecognised", which may or may not be "novel") organisms, It may not be your cup of tea, but it's a perfectly normal part of natural history interests.

Yes, it is exactly the same itch of curiosity that leads to people writing new software that suits their needs better than existing software. Just differently directed.

Comment Do people seek out OSS intentionally? (Score 2) 38

I know I do, but I mean more specifically, do enough people seek out OSS to keep it around? I go looking for OSS solutions both to save money of course but also to be able to have the code so that I can update it if it breaks later. I have successfully done this several times despite not being much of a programmer, getting hints by googling compiler errors.

You bring up an interesting point worth the 3 body problem and randomness.

Classical mechanics is not computable, for exactly the reasons you gave.

The idea that the error grows exponentially with time doesn't make sense exactly in QM because it's grows compared to what? This is where Heisenberg's uncertainty kicks in. There's no underlying ground truth here. In classical mechanics the position and momentum have infinite precision making them not computable. There's is a truth and any computation is an approximation which diverges exponentially. But in QM, the more precisely you know one, the more uncertainty must exist in the other. There's no underlying ground truth that your hypothetical computation diverges from.

Instead you have a probability distribution of position and momentum, and as time grows forwards that distribution expands. At some point it expands exponentially, but nonetheless the distribution itself is computable. The randomness doesn't make it computationally harder, it's what makes it computable at all compared to classical mechanics.

And speaking of computable...

In terms of the brain and complexity, that's not what computable is about. It's not about practicality. It's whether a Turing machine with unlimited tape can compute or in finite time. There's no difference between an ant brain and a human brain there. If you can compute the ant brain, then human might take exponentially more time, and indeed longer than the heat death of the universe. But that's an irrelevant practical consideration mathematically speaking.

Upshot though is Boolean logic is not known to be inadequate for stimulating human brains.

Comment PS2 was the last old school console (Score 1) 22

You might say it was PS3, because Cell, but most early titles mostly ran on the PPE and used the SPEs only for graphics, which is a lot like today's systems. The PS2's architecture was super interesting, being made out of multiple weird MIPS cores glued together with an ordinary one, and in weird ways. That generation is also obviously notable for being where the writing went up on the wall for highly custom consoles, with the PC-based Xbox. Even though Microsoft themselves built a fairly interesting console in the following generation — tri-core PPC is weird, even if in other ways it was not very extraordinary — since then everyone but Nintendo has built just crippled AIO PCs.

Comment Re:Around the truck? (Score 1) 78

It doesn't matter where they are stopped, within 10 minutes of a stop that lasts that long they must be placed 10 feet aft, (assuming you're on the right side as you're facing) 100 feet aft, and 100 feet afore. That means they're walking 10 feet aft and placing one, 90 more feet aft and placing another, 200 feet forwards so they're placing one 100 feet ahead, and then 100 feet back to their rig. I am admittedly not great at math, but this seems to me to add up to 300 feet, unless you've got two humans in the truck willing and able to place warning devices. In that case, each person only has to walk 200 feet, and I won't be so petty as to count both of their steps since nobody has to walk the full distance.

With that out of the way, let's have a more interesting discussion. There's no reason why a vehicle cannot have self-deploying reflective warning triangles based on radio controlled vehicles. It should be doable with vehicles wholesaling around $100. I think it would be most prudent to use tracked vehicles. It would probably cost more for something to pick them up off the ground again than for all three. And come to think of it, better to have four just in case. Alternately, how about a flare mortar? Wink wink for the many humor impaired out there.
