From the abstract: > When run on a wide variety of benchmarks, including the POSIX shell test suite, PaSh-JIT (1) does not break scripts, even in cases that are likely to break shells in widespread use; and (2) offers significant speedups, whenever parallelization is possible. These results show that PaSh-JIT can be used as a drop-in replacement for any non-interactive shell use, providing significant speedups without any risk of breakage.
The history of ThinkPads is that they tend to be boring business machines with boring business features like the ability to open them up and upgrade the ram or replace the SSD (they also used to have easy to replace batteries but I think they're all glued on now - at least in the lighter-weight models).
@mcc Dunno if the deals are good or bad, but we have a ThinkPad T14 (no idea what generation) in the house and it's pretty good for Linux. (personally I like T14s better - the T14 feels bulky. But there's a price premium). I seem to recall I had to mess with Debian images with additional non-free firmware to get it going (for the wifi, I believe), though
I'm not sure if ThinkBooks are good - I stay away from anything Lenovo innovated after they bought the line from IBM.
