Comment Re:RTOS (Score 2) 41

Don't generalise. There are plenty of scenarios requiring safety certified software lawyers that don't require the precision of an RTOS. We're not talking about deploying airbags here. Many applications in a car already are too complex (e.g. machine vision) to be baked into firmware on an RTOS. Yeah this won't replace your ECU, or your airbag system, but there there is far more to a modern car.

Comment Re:Um, excuse me? (Score 1) 301

The issue is that solar abundance is being systemically interpreted as a failure rather than a benefit because of its financial implications to business. It's not a technical issue, but a political one. Power producers are being treated as the constituents rather than the consumers, for whom too-cheap-to-meter power is an overwhelming benefit even if it applies some of the time.

Comment Re:Why so slow to refuel? (Score 1) 148

Hydrogen isn't stored at low temperatures. Hydrogen is dispensed at low temperatures. There's typically a standard storage bullet > compressor > small high pressure storage (enough to fill only a couple of cars per hour, sometimes no storage at all), and ... a chiller. The hydrogen is specifically cooled prior to being pumped to the car as pumping hot hydrogen is painfully slow, will prevent your tank from being filled to rated capacity, and can potentially cause a pressure spike if mixed with cold storage in a tank.

To me, this looks like poor design of the pump and/or the car. Heat tracing, anyone?

Quite the opposite. Hydrogen storage at stations is at a low pressure. The feed the hydrogen through a compressor directly on the way to your car. The issue here isn't cold, the issue is heat from the compression stage. The hydrogen then goes through an additional chilling phase cooling it down below zero before being dispensed into the car. The nozzles and hoses are insulated.

If the cold isn't maintained there's a few issues:
a) the filling process is slow. I mean REALLY slow. 20+minutes to fill a car.
b) you can't get the tank full. Hydrogen volume for a given pressure is governed by temperature.
c) you do run a potential risk in the worst case scenario: feed of high temperature into a nearly full low temperature tank can cause a pressure spike beyond safe operating point (which for a consumer car being 700bar should scare you a little).

Comment Re:8GB is only to claim lower starting price... (Score 1) 438

Very highly doubtful. Apple's better memory management through compression & faster access to the on-module RAM have made the expectations of those used to x86 laptops overestimate the RAM needed for all but the most demanding workloads, as has been seen time and time again by those who actually used one. Come on admit it, you're basing your opinion on a win/linux PC & not through actual use of a M1/2/3 Mac with 8Gb.

Comment Re:Well duh (Score 1) 148

What I like about their FUD is that in some cases hydrogen is actually just as bad. One of Toyota's talking points is how it takes more than 10 minutes to charge an EV. Yeah well Toyota loves telling people that you can get 300km of range out of a Mirai in just 5 minutes. They don't tell you that to do so you need to use a chilled high-rate dispenser (not all are), and they don't tell you 300km means the tank is actually less than half full.

Comment Re:Predictable (Score 3, Insightful) 148

The problem I believe is that hydrogen is so far very expensive, and so even though that trucks make a good fit as far as infrastructure goes, the price probably discourages commercial operations.

Hydrogen isn't expensive. Heck we produce a shittonne of it just to get gasoline and diesel into your car, and some refining processes actually produce net hydrogen as by-product, in many cases well beyond current demand to a point where you're borderline giving it away.

No the issue for hydrogen vehicles is far more ... dangerous. People don't understand hydrogen isn't gasoline. People don't understand gasoline pool fire burns down a petrol station, while a hydrogen bullet BLEVE levels 4 city blocks. People don't understand that gasoline is actually hard to ignite (throwing your cigarette at it only really works int he movies), while hydrogen is just standing there saying "common m*****uker move your jumper causing some static build up, I ****ing dare you!"

That's one of the reasons hydrogen infrastructure is going backwards. The companies have done their risk modelling and realised what a completely horrible idea it was. I've seen modelling from one oil major saying you can't build these fuel stations within 300m of any building. Then you see on the Toyota Mirai Europe website a lovely picture of a Shell / Vattenfall branded electrolysers / fuel station right in the harbour district of Hamburg. Except look at it on street maps, and it's obvious Shell actually realised what a horrible idea it was and backed out of the project *after* construction. That should give you moments of pause.

Comment Re:Not Fedora's biggest fan. (Score 2) 49

Anytime someone is excited about Fedora, I'm immediately suspicious and it's almost always justified later on as I learn more about them.

I generalise this far more. See I'm immediately suspicious of people who turn the concept of someone using a distro into some culture war labelling others. Somehow the people who judge others based on a distro they use are all the same gatekeeping arseholes, typically with some anti-systemd thrown in for extra toxicity.

You're like a vegan. How do you know someone hates systemd? They'll tell you, loudly, publicly, angrily, rant about it, then announce to the world that they judged you for daring to not give a shit.

Googlers are supporting a corporation that's violating privacy and enjoying monopoly or at least oligopoly power in many areas of business.

Yes let's equate violating privacy with contributing to a regime very likely committing war crimes. Tooooootaaaly the same thing worthy of the same response. Fuck you for gaslighting the protestors.

Comment Re: It's called work (Score 1) 215

All it takes to permit atrocities is to say you're disturbing someone's peace?

At work yes. Work is not a democracy. It is not there to look out for you. It's not your family, your company is not your friend. You are paid in exchange of services under a contract. Nothing more, nothing less. The contractual terms allow parties to part way often for all manner of simple reasons. If your employer permits atrocities your choice is to ignore it, leave the employer, or argue with them and be shown the door.

That's all there is to it. No more, no less. If you bring your politics and free speech and pointless rights to a place defined entirely by a work contract and limited contract law you should expect to lose any fight you start.

Not talking about politics (whose politics?) is what gets us into this mess.

There's a place for politics. Work isn't it. You're not paid for politics, you're not paid for your opinion. You want to have an open discussion in a public arena, go your hardest. You want to bring politics in a place in breach of your contract, well not liking the contract was your idea, and I'm with you, lets tear it up and don't forget to take your stuff with you on the way out the door.

Just another in the long list of failed 3D headsets going all the way back to the Nintendo Virtual Boy. Don't worry, someone will try again next year.

Maybe people just don't want to wear obnoxious heavy goggles on their head?

No they clearly do. You can see that from the sales of the Quest (which since you compared it to something like Nintendo, is actually more popular than the well regarded Gamecube). What people don't want to do is pay $3500 to wear obnoxious heavy goggles on their head. Devices which lose the trailing zero sell extremely well.

Comment Ban them except for executives. (Score 4, Interesting) 91

Executives are the one area where noncompete actually makes sense: Their leverage is already so high that their personal interests become a direct and potentially illegitimate threat to companies they intend to leave. Similar to the "mercenary general" model of historical warfare. But in anyone else's case it's an overblown or nonexistent problem, and the only reason companies do it is as a power flex.
