I ssh in from my XPS 13 running Fedora and use X forwarding to do work on it. It's so much faster than trying to do everything on an ultrabook. Not to mention quite a bit cheaper than a high-end laptop.
The VSCode remote extension installs extensions onto a VSCode remote client installed on the remote machine. So the C++ extensions spawns rg processes on the remote which is a lot faster.
I was under the impression that sshfs is based on FUSE, which works in userspace.
I think some may discount Ryzen 9 because it's technically not "HEDT", but the market boundaries have changed over time.
HEDT used to include all CPUs more $400 dollars, all of which shared the same socket (for a given generation). Mainstream was on a separate socket and all below $400.
However, Broadwell-E and Skylake-X moved the top end of the HEDT from $1K to $2K, which meant that HEDT spanned a huge segment.
What AMD did with Ryzen 9 and X570 was to take the middle segment of that HEDT market and make it it's own segment.
It did carve out a pricing segment there, but the really cool thing is that it's so compatible, backward and forward with other CPUs in the Ryzen family. There is huge upgrade potential.
It would be entirely reasonable to build a system around an R7, with the expectation that its workload will grow, and throw in a discounted 3950X in a year when Zen3 hits.
It sounds like an amazing build, but definitely not needed for most tasks. The XPS 13 seems a little wasteful in the setup. You could practically do it with a chromebook.
-U series (somehow, magically the same designation between AMD and Intel) will typically run ~15W, though this is configurable by the OEM (sometimes in BIOS?).
-H series (also, magically the same designation) will typically run ~45W, and this is also configurable by the OEM.
The increased power envelope of -H series typically allows higher base clocks. Turbo can sometimes be close between a 15W and a 45W chip, but a -H series will be able to maintain higher frequencies for longer, thanks to a superior thermal solution.
