- TSMC has announced performance specs for its upcoming 2nm node. (Tom's Hardware)
Compared with the current leading-edge 3nm process, it uses 24% less power for low-power mobile chips, and 35% less power for desktop chips. Or if you keep power the same, it runs about 15% faster.
Compared to 5nm, it uses around 48% to 55% less power, and compared to 7nm (which I'm running right now), the reduction is as much as 70%.
Chips will be coming off the production line in 2026.
Tech News
- If your company licenses the enterprise version of Windows, Copilot doesn't work and will never work. (Thurrott)
So you can go ahead and reassign the Copilot key on your keyboard now.
- A Transatlantic Tunnel, hurrah! (Newsweek)
Harry Harrison aside, this article is garbage. Newsweek was overpriced.
- Hackers are very clever idiots. (Ars Technica)
They went to extraordinary lengths to steal the credentials of 390,000 security professionals, and then installed a crypto miner guaranteeing they'd be spotted instantly.
- Canadia healthcare technology company Care1 leaked 4.8 million patient records totaling 2.2TB. (HackRead)
Nice work, guys.
Disclaimer: That was sarcasm.

"the 23.5-mile Channel Tunnel linking England and France took six years to construct"
Well, I mean, they started digging in the 1880s, so I guess that's only 6 years.

Also, this is just Elon Musk's stupid hyperloop (Hyperloop? HyperLoop? XyperXoop?) under water. Could we build it? Yes. Would it work? Maybe. Reliably? Doubtful. Economically? Never.

Actualyl, plate tectonics may be a significant obstacle to engineering long underground tunnels. Possibly inside cratons would be more easily doable, but there should be some fundamental limits on Earth.
Cars would probably need 20 to 30 hours minimum, so significant rest stops would be needed.
That means rail. The problem of rail is the trade between high speeds, and the expansion joints to accommodate rock motion over those distances.
Obviously, continental rail means that these can be solved. But, you can have a lot of information about surface motion in advance of planning a rail route.
Subsurface motion, at current state of the art, might mean needing to understand how to build the rail, well after the tunnels have been made.
I dunno.
