`wezterm ssh` can do this if wezterm is installed on the host.

Because an eV is a unit of energy (1 eV = 1.602e-19 Joules). It's defined as the kinetic energy of an electron that is accelerated by a potential difference of 1 Volt, nothing to do with its rest mass.

When rest mass is stated in energy units such as eV, they're calculating it using E=mc^2.

Yep, archlinux with gnome 48-testing with experimental features enabled to allow VRR, as well as fractional scaling. I prefer using my 2.8K display at 150%. Appears to be working fine with everything I've used. I have had some issues with wifi cutting out intermittently, but I think that might be a misconfiguration of roaming on my APs kicking the laptop too eagerly.

power-profiles-daemon works well, I didn't like how much the battery drains overnight on the s2idle suspend mode, so I've set up a systemd unit to hibernate after 30 minutes of sleep.

By what metric? I think this is close to true for identical blocksizes, but most benchmarks test sequential transfers with large 1M blocks and random ones with small 4K blocks. In this case, the speed of the fastest NVME drives is more than double for sequential transfers than it is for random ones.

I don't like comparing the two, they're completely different workloads and it's better IMO to look at the IOPS for random transfers, which is where newer, faster SSDs truly excel, and where most people "notice" the performance.

I am a plasma researcher, though not in the fusion field. Containment and stability are required on tokamaks to keep a plasma burning. Losing either of these will quench the reaction. The best way to control a plasma - magnetic fields, also causes significant instabilities, which is why fusion is so difficult.

Weird take. The assembly process was dead simple and impossible to screw up if you follow the clear instructions. There are threads on the forum for memory compatibility. Pretty sure they assemble and test every device (even diy ones) before they leave the factory.

Yes, I would recommend it. I have a DIY edition framework 13 with the AMD 640U) and new 2.8K display. It has been working perfectly for me with archlinux installed (even though it's not one of the recommended distros). Battery life has been decent when using power profiles daemon, but nowhere near as good as an ARM macbook. I would definitely suggest the upgraded display, as this also lands you the larger battery. The keyboard is great, trackpad is pretty good and no issues with wifi, nor bluetooth. A brighter display with wide colour gamut and higher accuracy would have been nice, but the 2.8k display is not bad at all.

That being said, it's definitely more expensive than much of the competition is for similar specs. I don't mind paying a little extra to vote with my wallet and the build quality has exceeded my expectations. I'm gambling on them supporting this chassis design for a few more generations, so I can buy the very last motherboard upgrade that they release and extend the life of this machine a little further.

I suspect it would be a very challenging problem for the earpiece part to recreate the directional info as well as our own ears, since the brain's ability to detect the direction of sounds depends on the shape of the ear itself.

Maybe a simple mechanical clicker device like those used for dog training could be a useful tool.
