Nissan's Autonomous Car Now Road Legal In Japan

davburns Re: Curiously? (205 comments)

It seems that state-to-state (or even city-to-city) variations in law pretty much just requires that a lawyer and an engineer sit down and code up the statutes, right? Then do simulator testing? Then the car can download them as needed. I'd bet that autonomous (or semi-autonomous, as I think better describes this one) cars will do a better job at that than out-of-state drivers.

Ask Slashdot: Best Long-Term Video/Picture Storage?

davburns Make lots of copies (499 comments)

None of the originals -- or even 2nd or 3rd generation copies -- of any ancient or classical era literature have survived to the present day. What kept the works from being lost is that there were lots of scribes making lots of copies, and spreading them around. People did this because they thought they were good, so they went to the expense of having a copy made.

For your pictures and videos, even if you're not thinking of keeping them around for thousands of years, do the same thing: Make copies and spread them around to people who want copies. Convert them to different formats, too (Try to keep some high-quality, non-DRM copies for the next format as well). Don't just think in terms of having a monolithic collection (like the Library at Alexandria) either. You want each grandparent, aunt and cousin to be helping you to curate a distributed cloud of record.

The "obvious" tool here would be The Cloud -- but be careful. None of Google, Yahoo!, Amazon, or Facebook really cares about your pictures; they care about the revenue they can make by keeping a relationship with you. They're kindof like ancient scribes. Let them help you with the making of the copies, but don't let any of them (or any subset of them) keep your only copy for very long.

Do Tools Ever 'Die?'

davburns Re:The Internet in anti-government actions (615 comments)


I think that turning off the Internet is pretty much an admission that regime change is inevitable. A legitimate sovereign power can enforce its laws without completely blocking everything.

You might as well suggest that ballot boxes are dead tools because they haven't been used in Egypt in a few decades... but they aren't, and they'll probably be used again very soon.

Intel Says Brain Implants Could Control Computers By 2020

davburns Re:Why implants? (314 comments)

I was thinking that, too.

The oldest computer I have around is a 1990 Amiga 500; I mostly use new kit, of course. Anyone who gets an implant is going to be stuck with it pretty much for life, or commit to brain surgery every 3-5 years to install the newer one.

On the other hand, a 'trode net or hat would seem doable; sign me up for that.

Me, too
I wonder if we'll be able to hear the giant sloshing sound -- starting 24 months after the iPhone 3G came out -- of everyone moving away from AT&T / iPhone to whoever is offering a good plan with reasonable price/terms/etc. On the other hand, the iPhone is still a (historical) game-changer, in that it got everyone away from horrible dumb-smart-phones that couldn't even keep a calendar in a user-friendly way.

ARIN Letter Says Two More Years of IPv4

davburns Re:economics as usual (266 comments)

No, the problem is that we really do need more address space. IP addresses include identification information and network topology information. We really do have almost that many computers, and almost that complex of topology.

Forcing the holders of large legacy allocations to give them up would hurt more than moving to IPv6, and it'd only get us a few more years of IPv4 growth. Opening up the class-E space would also hurt more than moving to IPv6, and still only give us a few more years.

NAT effectively adds 16 more bits to the address, but does so on a per-connection basis, not a per-node basis. It requires the network to be stateful, instead of just passing packets while the end hosts carry all the state. (This means that the end hosts can't just route around problems.) NAT is messy, but it happens to work because it can steal some bits of TCP or UDP to make up for not having enough in the IP header.

IPv6 adds way more address space than anyone can think of a use for. So it can encode a lot of information about the node's position in the network, plus keep an address unique for (practically) ever.

What Kind of Data Center Can You Build With $500M?

davburns Re:Old Tech Costs? (204 comments)

Was it cheaper when they did it all with paper files?

Yes, but mostly because there were a lot fewer people back then. (Remember, that even sorting is O(N log N) -- and you have to do that to get the right papers in the right files. I would guess that there needs to be lots of O(N^2) operations to catch fraud. 300,000 Americans is a big N.

Google Engineers Say IPv6 Is Easy, Not Expensive

Google Engineers Say IPv6 Is Easy, Not Expensive

davburns opt-in (233 comments)

Google does publish ipv6.google.com. And if you have classic (not ig) selected, you get an extra-fancy dancing Google logo to let you know you made it to the IPv6 version of Google.

But if you want to use their regular services, they just redirect you to plain old boring www.google.com. So it's nice that Google spent 20% of a lot of time on this, but it's not available to ordinary IPv6 connected users. I guess that's better than slashdot. (ipv6.slashdot.org has an A, but no AAAA records!)

Of course, if you want to add some entries to your ipnodes table, you can get the rest of the Google services to work for you over IPv6 and then your gmail will be extra-cool like mine.

Google's Information On DMCA Takedown Abuse

davburns Re:So... (217 comments)

The DMCA notices I've seen only swear to be authorized to act on the copyright owner's behalf, and/or that there is an exclusive license which the alleged file sharer doesn't have. The details about IP addresses, protocols, and timestamps are (at best) represented as a "good faith belief." It's never been clear to me if those sending the notices are making any claim that the

Do you have a reference for your claim that the entire notice must be filed under penalty of perjury? I have some that are completely implausible, and others that for which I have some doubt. If this were indeed perjury, that would probably be interesting to lawyers defending clients from similar evidence.

I use whatever window is open, and that's generally a lot of them. pgsl is very good at dates, but one can select almost anything you really need, too. bc -l works from almost any shell. google is smart enough for easy stuff.

Of course, someone will probably say they just PM CowboyNeal in IRC, but I actually prefer to do the easier calculations myself.

GM Cornered Into Defending the Volt

davburns Re:hydrogen cars (769 comments)

Since hydrogen has, at a theoretical best, a 1.0 eROI, it should never be considered an energy source.

Modern batteries (or even flywheels) are better at storing energy than stored hydrogen. The electric grids transmit energy more efficiently than hydrogen can be transported (except to exotic places where installing power lines is difficult. Like on a launching space shuttle.)

davburns Re:Can't believe I'm first, second, and third (534 comments)

I think you can get that with a single spinning design. You can run in the same direction as the rotation (basically, faster rotation) and get a good workout. Or, you can leap in the opposite direction, and get around the rim pretty quick. Or you can just hang out in the "hub" and let the station turn around you.

IANA allocates 2 /8s to APNIC, exausts freepool

davburns davburns writes  |  more than 3 years ago

davburns (49244) writes "The Internet Assigned Numbers Authority has allocated two /8s of IPv4 address space to APNIC. This also triggers the IANA to allocate the final five /8s — one to each of the RIRs. APNIC suggests that this will hold them for three to six months. After that, sites without IPv6 have something less than full Internet connectivity. Potaroo has a slightly longer estimate of September when RIR Unallocated space is exausted."

davburns davburns writes  |  more than 7 years ago I've been putting this off for a week, hoping that RacePhotos.net would give me the visual aids I want, but they're being slow, so I'll spread the news with minimal help from them. (But if you go there and enter my 5677 number, you can see some of my pictures -- I'm the guy in the red shirt and black hat. Or you can ponder stats and at runpix)

So, I ran my first 26.2 miles last Sunday. It was fun. It was long. It hurt.

I had planned to finish in 5 hours 20 minutes (about 12 minute miles). The first half was almost exactly on pace, but the second half (and therefore the whole) took almost an hour longer than I'd intended. 6:19:05

I tried to come up with 26.2 excuses for being so slow, or even 13.1, but was unable to do so; I think 1 and 6 will have to cover more than one mile of slowness:

  1. So... 19 aid stations do not provide enough water, even at 2 cups per station. Who knew?
  2. Okay, two 20-mile run/walk's were not enough. Sure, 15 mile training runs help, but still not enough.
  3. ...and the 20-mile run/walk's were heavier on the walking than they should have been, because of a shoe-fit problem
  4. ...so the shoe-fit issue meant I had to get new shoes about a month before the race. Sure, I broke 'em in a bit before, but it was less than the recommended 100 miles.
  5. 1.5 weeks before the race, I got a cold. I think I was over it before the event, but it wasn't the best thing for pre-event tapering.
  6. Hey, did you know that insufficient water causes PAAAAAAIN[*] in the quadriceps when running? I sure do now.
  7. None of my training included trying to pace myself for the first five miles, while people are lining the streets, cheering me on, and bringing their boomboxes hooked up to megaphones, playing the theme from Superman. Would the son of Jor-el be holding back now?
  8. Actually, all of my 15 mile or longer training runs were in much warmer temperatures, and I paced myself by how hot I was getting. That did not work so well at 7am in October.

[*] Think Mr. T's prediction in Rocky III

Anyway, I'm mostly un-sore now. I learned a lot. I keep thinking about how I could do so much better next time -- and then catch myself; why would I do this again ?!? I guess I have a few months to decide. I've had a huge appetite all week -- I think my body has finally decided that I must be serious about this running stuff. (just in time to wind down for winter.)
