I wonder what would happen if Canada taxed electricity exports to the US, and used the money to directly subsidize other exported goods the US applies tariffs to?

Do the numbers in that article make sense? 5.8g/km for tyre wear? Generally my tyres last maybe 25000 miles. So at that rate they would lose 230kg. Seems high.

Tyre, no, but regen braking almost eliminates brake particles at the speeds I drive in London. But mostly I take the train. Unfortunately the highest I measured on my particulate sensor is not near the roads, but in the tube.

Coming back from the pub? At least when I'm on a train at 12:41am, that's usually the reason.

Thinking about it some more, it really is about consistency regarding the cursor. On my trackpad, not in "natural scrolling" mode, I get this: - One finger down moves the cursor down through the text. - Two fingers down mov

It's not just the ergonomics - in my head I'm moving the cursor (and with it my view) down through the document, not moving the document up. Which is mentally different from a touchscreen, though I expect people who grew up with

If you want more details, there's the protocol spec from OCP [0] and a paper [1] [0] https://opencompute.org/documents/ocp-mrc-1-0-pdf [1] https://cdn.openai.com/pdf/resilient-ai-supercomputer

Back when replaceable batteries were the norm, I had two Blackberries that survived going through the washer and dryer.

Agree about the watch - I wear a Casio LCW-M100TSE, which is also very robust (titanium case, saphire glass), never needs the battery changing and never needs setting (except for travel). But most importantly, it does what it does really w

It seems like trucks are a use case where battery swapping would make a lot of sense. Unlike with cars, the battery doesn't need to be a structural element, and there's much less need for it to be a strange shape, as in some cars

I don't see her later on in the news article - just in the video. Did Apple remove the picture after you pointed it out?

Neutrino mass is another anomaly, which is at least slightly easier to probe than quantum gravity: https://cerncourier.com/a/the-neutrino-mass-puzzle/

I'm British, but when submitting papers for blind review, always use American spelling for obvious reasons. I suppose I could change it after acceptance, but that would just be pretentious.

I've used bubblesort when simulating LEO satellite constellations, calculating which satellite is closest to a location. I used one single backwards pass of bubblesort, so O(n) every k timesteps to bring the closest to the head of the

And if you do get one somehow, it's really hard to spend. Many places won't accept them.

It's definitely possible to break the rules. In fact, to give a truly outstanding talk that everyone remembers, you probably have to break the rules (speaking as someone who coded an entire Sigcomm presentation in a 3d game engine). B

If you have two pipes of the same height, one filled with fresh water and one with salt water, the pressure will be greater at the bottom of the salt-water pipe because salt-water is denser. Connect them at the bottom with a pipe and water

If we had 9-bit bytes and 36-bit words, then for the same hardware budget, we'd have 12.5% fewer bytes/words of memory. It seems likely that despite the examples in the article, in most cases we'd very likely not make use of

I also started using Jove back when 30 of us shared one PDP 11/44 running BSD Unix, and it was antisocial to use something as heavyweight as Emacs. 40 years later, I'm still using UNIX and Emacs.

I've spent the last few weeks writing a non-trivial distributed system using Codex (OpenAI's agentic coding system). I started by writing a design brief, and iterated with o3 to refine it so it was more complete and less ambiguou

That sounds reasonable for access to actual content, but it produces a huge new incentive to constantly produce vast amounts of AI-generated slop served via Cloudflare. Is there a way to disincentivize this?

I came of age in the 8-bit era of the early 80s, rode the Internet wave of the 90s and early 2000s, kind of missed the mobile wave but spent that time developing ideas that would eventually turn out to be useful for AI, and now I'm hav

If it's really just 1m behind, it doesn't need to respond individually to anything except pedestrians. And you can solve that with some extensible tapes that actually do connect the vehicles to prevent pedestrians walking between

With computerized control and a comms link between the vehicles, you could probably have one vehicle follow 1m behind another, so they are effectively a train. If you still have a driver at all, you only need one in the front vehicle.
