I would love to buy a car with only FOSS software or at least source available software available inside. In the long run, I think it would be much safer than the status quo and with everything becoming computer-driven. I've thought about doing something like this with my center nav, but it deals with setting the time on the mirror among other things. Still, I can't get updated maps without paying the dealer a few hu…

This is something I'd at least expect from Tesla, the company who open sourced all of their patents.

How exactly is it separated? I imagine the ideal solution would be using two airgapped computers, one for the main car system, one for the media stuff, and then keep the servers from which they receive updates, and the authorization for those servers completely separated as well, with the updates done by different people, too. But I imagine the vast majority of car makers don't do anything close to that, and probably…

It's incredibly complicated, but pretty secure. The CAN bus is isolated from the network. I have root access on the CID and the IC (both separate tegra systems). You can even reboot the CID while you're driving and you only lose media and air conditioning and such. Accessing the CAN bus requires going through a pretty secure gateway system, so you can only basically make requests. Even then, I haven't even really loo…

Sensible cars have a device bridging high and low security networks, forwarding data from one to the other, specifically so that a misbehaving media device or light system can't clobber the brakes or ECU. No idea if the Tesla does this or not, but it's a fairly standard approach.

Yes, it has a gateway between the high level stuff and the low level stuff. It's fairly secure too. You can't just make calls to the can bus all willy-nilly either.

though wasn't the chrysler attack through one of these gateways?

Even if this is supposed to be funny (I can't tell, so I think you may have failed if so), I'd like to correct you and say that what makes Gentoo tick doesn't hinge on GNU at all. We can run on different kernels, different libcs, and coreutils are just a package you install. Might be toybox for all Gentoo cares! As far as I'm concerned, Gentoo is the most underappreciated distro. I'm a Gentoo dev, but that's not why…

I wonder what happens when you get into a bad crash, somebody decides to sue, and it comes out that your car was running modified software. Would you be exposing yourself to any liability?

Aren't you already liable for all damage in an at fault accident? If you modified it yourself, I'm not sure there's any blame that can be shifted around.

If whoever you hit's lawyer manages to make a case that the accident was worse as a result of your modifications, you might have a problem.

Dude you are my hero. I look forward to the day that I can sit in my car with my friends, smoking something, watching a movie, and letting the self driving vehicle wander around LA while we look for interesting places to stop and explore. I would never use my couch again. Edit: If tesla begins making showers I may not even need an apartment.

I will buy it too, if there is a toilet in the car!

Generally only in the second person, though. Third person (this dude was pissing me off, or "it's a dude!") usually means male.

No, "Dude, you rule" is definitely gender-neutral by now.

So is "man". As in, "You totally should have gotten than promotion, man." Or "Man, I really love this pizza." Yes, it's used gender-neutral. But both historically and in common practice it's a noun, verb, interjection or vocative adjunct that most commonly refers to a male.

That aspect, that it was at one time, or still is, gender-specific, is what makes it inappropriate to call a person who doesn't identify with that gender. Like many other words which can apply to more than one kind of person, you have to think about how the listener will interpret it, not how you want them to interpret it.

Finally something interesting I read here on HN from a girl in IT. She's the one other girls should be proud of and looking at as a role model, not the feminists.

I'm disappointed to see a comment like this here. To treat 'feminists' as a monolithic bloc, mutually exclusive from meaningful contributors to IT, is insulting to those of us who try to be both. Women in tech face real challenges, including but not limited to casual condescension towards the people fighting for change. I'm proud of her too, and I'm sure she's exactly the sort of role model that a feminist would have…

I'm sure that many women in tech have problems, although I view them as equal whenever I work with them. Also I am sorry if I hurt anyone's feelings with my comment. I'm just not sure if it helps the general view on women in tech that I read 4 times as many articles complaining about the problems for women to achieving something technical.

The chrysler was a completely different system, but it was indeed infecting the car from the radio / entertainment system. The tesla is completely different from that. They have one entire computer system that runs the "entertainment console". You can even reboot it while you are driving and nothing happens (this is by design of course). The driving controls are totally separated. The only thing you notice when you reboot that console if that the radio goes off, the display goes black during the reboot (10 seconds). Then it comes back and all is well. Press both turning cylinder controls on the steering wheel for a few seconds to start the reboot. They designed it very well. That doesn't mean it is perfect, but they have approached security correctly as far as I can tell from outside. They pay for exploits too - see https://bugcrowd.com/tesla. They have hired security researchers to work on their system and attack it.

As a tesla owner, I do wish they would hurry up and publish their app platform. They do have apps that they wrote themselves, that come with the car.

And I really wish they'd update their web browser, and even more wish they supported linux. Maybe the chromebook os support will be secure enough for android apps that even tesla could use it.
