  Let's play a game: Post the oldest image of your "battle station" / computer setup that you have. Ideally, post some specs of the system if you can remember. I'll start: - photo from 2003 - Pentium II, 350MHz - 3DFX Voodoo Banshee - 1024x768 17" Eizo CRT - Iomega Zip drive, 100MB via Parallel port (*click!*) - SCSI Scanner hidden away in the background I think the Mac was a Power Macintosh 6300, but I'm not 100% sure. What are yours? :) #retrocomputing

  Modern PC hardware is real RF voodoo these days: DDR5 runs at 5+ GHz, PCIe 5.0 runs at 16 GHz (!!), networking/SFPs running at 26+ GHz, often using advanced modulation like PAM4. All of those ultra high speed links are doing some form of equalization/link training and their hardware is very often capable of measuring/reporting eye diagrams.

  Wrote a driver for osmo-trx to run on the PlutoSDR. PlutoSDR is a relatively inexpensive Zynq (FPGA+ARM) and AD9361 SDR device. It runs Linux and can run smaller applications directly on device. I'm now using it to run a 2G/GSM base station setup. The transceiver runs directly on device, the rest of the network needs to be external. Made possible through 3rd party timestamping FPGA gateware written by Phil Greenland. https://github.com/Manawyrm/osmo-trx-pluto-fw

  Just patched a long fiber link, which would've absolutely _sucked_ to get CAT.7 cable through. The steel-armored OS2 cable is cheap and super robust/easy to work with. The LC connectors are even smaller than the hole for CAT.7 would've been. This is nice \o/ What I want to say is: Don't be afraid of fiber for DIY networking people, it's awesome and often muuuch better than copper cable! I also didn't have to do any annoying LSA+ terminations or crimps a...
