Comment Re:that was bad. (Score 1) 127

Precisely. If you make mistakes like this expensive enough for the police station then the problem solves itself. The real problem is that someone promised the police and the school a magic new technology that would make their schoolyard safer. So far the system probably has zero wins, and one spectacular failure. If the political and economic fallout for the failure is high enough then the school turns off the crappy system, and it encourages other schools to do the same. Potential new buyers for the system disappear and the vendor of the system goes out of business.

And we all win.

Eventually the school might even end up with an effective system that does roughly the same thing, but it will likely be structured in a way that makes it less likely that Doritos wielding young adults get assaulted by the police. It's hard to argue against safer schools. In any system like this false positives are going to be a potential problem. If you make false positives expensive enough, however, then you likely get the outcome that you want.

Control over another human being is very much part of this. Maybe they wouldn't want to call it enslavement. At the risk of over generalizing or putting words in anyone's mouth; the entire culture around pseudo-libertarian Tech Bros and the broader Anarcho-capitalism philosophy is that it is extremely transactional. They believe that two people can come to a fair contractual arrangement, without government regulation or an impartial third party, Despite one person being a billionaire and the other person needing a job to pay their bills.

Comment Nuke bugs need to give it a rest (Score 5, Interesting) 97

Nuclear is not coming online in the US. Your choices now are: Renewables or frequent regional outages. Given the state of our infrastructure, I think a mix of both is in the future.

The USA has 21 proposed reactors. 0 under construction, 0 planned. It is unlikely any of the proposed projects could go online before the mid- to late 2030's.

It's obvious to you and to me that nuclear is the most capable and scalable and should be our primary choice moving forward.
Nuclear fission as an energy source is a dead end in America, and that has little to do with nuclear hysteria and more to do with infrastructure funding, NIMBY, and wealth inequality. (our bad politics are why we cannot have nice things)

But the reality is that we (the US) won't be taking the best option. So it's time to discuss secondary and tertiary options.

Comment Models are beyond criticism at this point (Score 1) 75

Yes, there are hundreds of different climate models. An abundance of models is not evidence that there is no such thing as climate change.

The value of a model is in its predictive power. If a model can bound historical data then the next logical step is finding the bounds of future data. All models have a greater spread the future they look into the future, because that's just math as you stack on tolerances over a greater time. You add up the error when you're looking at the extremes, but you also find a higher probability somewhere in the middle if your model is any good.

So assuming climate change is going to happen to some degree. What actions should we take to prepare for it?

Once you have a workflow with multiple toolchains, you're on your way to porting to any number of architectures. And automated testing of architecture independence in a codebase becomes practical. That's certainly how it worked out at my company. Once we started building for Sparc and PowerPC, it made other architectures easier to add a decade later. And we had the additional complication that a big chunk of the codebase is drivers. Getting ARM systems with the right hardware into the test automation pool was a big non-technical challenge. What manager wants to sign the PO to pay for duplicating all the x86 configurations with ARM? ;-)

Replacing assembler with compiler intrinsics helped simplify porting SIMD code between architectures. But in some cases we will just have to add a bunch of tiny macros or functions in assembler in order to do something like RV32 vs RV64 in the future. Not a big deal for us when a customer is paying for the work.
