I have found a trackball to be even better than a vertical mouse. Only your thumb moves.
Otherwise it's also Ergodox for me. I switched to Colemak at the same time, also have a programming layer ()[]{} etc. In addition I have a layer for cursornavigation and selection, word wise/char wise/start&ens of line/page wise, comparable to vim mode, but using the default shortcuts for Windows and macos (with the help of Karabiner)
It took a few weeks to get up to speed but I couldn't be happier.
Note that the tilt only has one level (flat and tilted), the animation might make you think otherwise. I use it in tilted mode.
It is highly customizable using the Logitech options software which I am using on both macOS and Windows. For example you can assign actions to all the buttons that are dependent on the running program, and even involve custom key combinations.
The only downside of the trackball is that you have to clean it once in a while, when the pointer appears to be moving very slowly - simply eject the ball by poking a screwdriver into the hole at the bottom of the mouse, clean out the accumulated dust and push the ball back.
Most of these techniques are engineered to not cause much of a performance degradation. Otherwise there would not be much uptake. Also they are often implemented in compilers which produce native binaries so the impact is low.
The mitigations for the various hardware sidechannel attacks discovered in the past year have a bit larger impact. But you don't need these at all on your local computer, only in shared environments.
As a rule of thumb each mitigation usually costs a single digit percentage, seldom double digit. Of course in a system multiple mitigations will be at play but the impact should be far below 100%.
The performance impact of scripting languages, interoperable web standards and bad implementations are far worse :)
Many people don't bother setting this up themselves. Others want to have a shared email domain similar to Gmail.com with their first name before the @, instead of their full name in the domain name.
AI can now generate verbose content from a short prompt. AI can also summarize verbose content.
I see a rosy future for AI. Humans will use it to transform their salient points into prose, and back.
Or we as humans could just do away with a lot of boilerplate pretense, and just communicate the important bullet points. This might rid us of a lot or jobs though so it probably won't happen.
Big chunk of memory - that's not the case except if you are using deduplication. I have it running fine on a 4GB machine (10TB mirrored volume) without any issues.
What I believe gp was referring to was that zfs uses different caching system that the main system. Specifically arc vs page cache do almost the same job, but are separate and may fight for resources. Discussed in a few places, but here's an example with some behaviour summary https://www.reddit.com/r/zfs/comments/o8xqzb/zfs_on_linux_ca...
