Submission + - Law for Autonomous Vehicles: Supporting an Aftermarket for Driving Computers (perens.com)

Bruce Perens writes: How will we buy self-driving cars, and how will we keep them running as self-driving software and hardware becomes obsolete much more rapidly than the vehicle itself? Boalt Hall legal professor Lothar Determann and Open Source Evangelist Bruce Perens are publishing an article in the prestigious Berkeley Technology Law Journal on how the law and markets might support an aftermarket for self-driving computers, rather than having the manufacturer lock them down or sell driving as a service rather than selling cars. The preprint is available to read now, and discusses how an Open Car, based on Open Standards and an Open Market, but not necessarily Open Source, can drive prices down and quality up over non-competitive manufacturer lock-in.

Experiments prove that swearing when in pain reduces the pain.

Google Stephen Fry and Brian Blessed video for a pop-science demonstration of such.

And in such instances, "fake" swear words do not have the same effect, even if you know what they stand for...

So... swear words are magic? I don't buy it. They may have an effect in people who normally think and use them, but that certainly can't be true for those who don't.

Most folks drink stale coffee. Try roasting your own (I use Sweet Maria's for supplies) or going somewhere with a roaster on site who is honest enough to tell you the roast date. It should be from 2 to 10 days ago. Flavor development in coffee is a rancidification process. Like cheese, you want to catch it when it is a little, but not too, rancid.

Comment Re:...Or Just Take Aspirin. (Score 2) 80

Let's not forget the effect of helicobacter pylori bacteria on ulcers, they are in general held to be the main cause these days.

I have another theory about the beneficial effect of aspirin, caffine, etc. We evolved with them. Our diet was rich in salycilates and chemicals similar to theobromine or caffine. They came from the plants we ate, some of which were mildly toxic and which we evolved to process to the point that we became dependent on some of their effects. There are a lot of things in the primitive diet that modern people don't eat much at all, like acorns which had to be soaked to remove alkalai and tannin.

If this is the case, taking aspirin and drinking coffee or tea replace substances found in a more primitive diet.

So if you only need a non-EV a dozen times per year, have you considered renting for those trips? You can rent a small (but decent) car for about $30 per day. Assuming each of your long trips was for two days, that would run you about $600 per year in rental fees. Whether or not fuel savings the rest of the year would offset that cost depends on many, many factors. Of course, this assumes that you have a car rental location within driving distance for your EV, but unless you're really out in the sticks, you probably do.

on top of which it's extremely expensive for what it is

Perhaps. I find that I really *like* driving an EV. The relatively high acceleration, especially off the line, plus the silence -- and the ability to warm the car up with the garage door closed on a cold morning -- are nice. I enjoy driving an EV more than I enjoy driving a combustion-powered vehicle, which is worth something to me.

I should mention that I own two vehicles. One is an EV (Nissan LEAF) which we use for running around. We live 20 miles from town, but it has enough range to run into town, do some running around, and get home. If we absolutely need it, there's a quick charger in town that we can use to "top up" to get home. 15 minutes there gives us enough charge to get home, but it's rare that we need it. My other vehicle is a full-sized pickup truck (Ford F350) with a big diesel V8. We use that for hauling stuff, towing stuff (boat, tractor (on flatbed trailer), camp trailer, etc.), tooling around in the mountains, etc. We sometimes use the pickup for long trips, but usually if we don't actually need the pickup we rent a small car. It's cheaper than feeding that big diesel (which gets 15-19 mpg).

My LEAF is leased and the lease expires next month. I normally buy vehicles and drive them until they die, but EVs were new enough that I wanted to be able to walk away. I think we're going to go test drive the Chevy Bolt, and if we like it we'll get one of those. We like EVs, but would appreciate just a little more range than the LEAF gets us -- to ensure we never have to stop at that quick charger.

People who don't swear scare the fucking life out of me.

I don't, except in circumstances where I'm deliberately trying to shock, or at least surprise. It's not a matter of "repression", it's that profanity is not part of my vocabulary. You assume that people who don't swear are "repressing" or "censoring" themselves, but that assumption presumes that they actually do swear in their internal dialogue, but then don't say it out loud. But I don't use profanity in my internal dialogue, either, though I suppose I have some stand-in words (dang, etc.) which fill more or less the same purpose.

To put it another way, a good friend of mine like to say "If you don't scream FUCK when you hit your thumb with a hammer, your head will explode." My response is "When I hit my thumb with a hammer, I'm in way too much pain to go to the effort of remembering to scream FUCK." He's assuming that the curse word will be naturally present and that if you don't scream it it's because you're holding it back. For me, the curse word just isn't there, so what happens when I hit my thumb is a wordless howl of pain. No repression involved, and my head remains intact.

In addition, I think profanity is generally counterproductive. Rather than saying that something is "fucking stupid", why not spend two more seconds thinking, and articulate why it's stupid, or what about it is stupid? Your phrase accomplishes exactly nothing other than to make people understand that you're angry. It conveys no other information and does nothing to rectify the stupidity. Also, it's pretty common that when people bother to think about what exactly it is that's making them mad, they discover that, in fact, it's not stupid and that they just hadn't thought the whole situation through.

Finally, I find that the fact that I hardly ever use profanity makes it a really powerful tool on the rare occasions I do choose to use it. Those who use it constantly have basically nowhere to go when the situation deserves a really strong statement.

Comment Re: most vulnerabilities != most vulnerable (Score 1) 147

because people report vulnerabilities against very old versions of Android which, while they do still exist in the wild, constitute a fairly small number of devices...

Android KitKat, which was released in 2013, is still being used on 22.1% of the devices out there. And 36.3% of the devices out there run KitKat or older versions of Android.

Gingerbread 1.0% Ice Cream Sandwich 1.1% Jelly Bean 11.6% KitKat 22.6%

Very true, and part of the reason that the Play store and Verified Apps protections are so important.

What complete and utter shite are you spewing?

Actual experience of my wife with H1-B employees (including the "chagrined when discovering the forged credentials" case).

When getting your H1-B you need to provide documentation from your university as proof of your degree. The university must be on a list recognized by the US government. They validate the information with the university rather than just rubberstamping it.

Any of the following would explain that:
  - The agency faked the references, too.
  - The government didn't do the validation you claim it does in every case.
  - The government doesn't do the validation you claim and you're talking through your hat.

Please put your flamage aside for the moment and give us a reference to documentation showing that the government officials actually check credentials, rather than doing spot-checks or taking the applicant's word for them (or bribes).

Comment Re: Not really needed for drones (Score 1) 22

Modulation designators that state the payload type don't make much sense with digital data transports. You can do digital TV or anything else with 4 MHz bandwidth. Cellular doesn't make much sense unless they have a really long hover time and drone life, in which case it could be a pop-up base station.
