Framework's 10G Ethernet module exposes USB-C's complexity
I've been following WisdPi's development of various 5 Gbps and 10 Gbps Ethernet adapters for the past couple years. They use newer Realtek Ethernet chips, which sometimes have performance quirks—most frequently encountered under Linux. In today's video, I tested the new WisdPi 10G Ethernet Expansion Card for Framework…

Why Drawing Tablet Brands Won't Collaborate on Linux Floss Drivers
As you probably already know, I regularly get in contact with drawing tablet brands for reviews on my Youtube channel . I usually agree to do detailed video test of their models (see my hardware tag) but only at two condition: test the tablet on GNU/Linux, and only use Free/Libre and Open Source software for the test…
