FPGA people: how cursed is it if I scramble TX/RX lanes of my transceivers so that e.g. TX lane 0 and RX lane 1 go to a single SFP28?
They're separate clock domains anyway, separate PLL taps. I'm not using the CPLL so that's no factor.
It feels wrong, but I can't think of any reason why it would be? (I've done this before and it worked fine but that was with hacky breakout to SMA setups, not by design on a PCB)

My JS Krups is resisting netbooting. I see it doing a DHCP discover, and I see Kea responding with an offer, but then it just sends another Discover. Hmph. I can get to the serial console and doing boot net from there doesn't help; none of the keyboard shortcuts for network diag etc seem to work (except the one that displays the help for it...). So I took the flash SIM out and now it boots to Net rather than flash by default; alas with the same DHCP behaviour. Time to try isc-dhcp.…

A serial console photo, showing a Javastation openbootprom 'ok' prompt and help and 'show-devs' output.  It's a boring white on black text.
The mainboard of a Javastation Krups, to the left are various connectors, just above middle is a speaker and below that the Microsparc,  to the right are two RAM dimms and a flash SIMM.
A horribly hacky serial setup; between two keyboards sits a serial breakout box, various wires and crock clip leads.  It's working by good luck rather than physics, The lights for RX/TX are green and the next LED is red.

No dark mode for SSMS?
SQL Shades to the rescue!
Free version adds plain dark mode to the IDE (fine by me.) Paid version supports additional themes.
This solution is cleaner than the rather hacky approach of modifying ssms.pkgundef to restore a half-finished dark theme commented out by SSMS developers apparently at the last moment.
