Anyone have a Radxa ROCK 5 ITX, ROCK 5 ITX+, or Orion O6 they'd be willing to sell me? I bought two ROCK 5 ITXs from Radxa directly, but one was DOA and they didn't have stock to replace it and couldn't repair it... and I bought a 2U chassis that is supposed to house a pair of Mini ITX boards.

I wanted another computer as a sandbox, I don't really trust VMs, and fucking chip shortages, so to the boneyard it is. I have a disused ASRock Rack J1900D2Y with 8GB of RAM and a PicoPSU that used to be my mail server. Somehow, at some point, I modded the 1U case to mount the rack ears on the back.

It seems that "Sex Matters", an anti-trans hate group run by Maya Forstater and funded by JK Rowling, did not appreciate being named as such in this report from Amnesty International. They seem to have pressured them to take it down, but I have a copy. transrightsnow.uk/Report_-_A_g...

Update on my legal case: The European Court of Human Rights has accepted the filing of my claim against the UK. The next step will be a judicial review to confirm admissibility, but I have no idea how long of a queue there is for that. Assuming it's admissible, a hearing will then be allocated.

The age verifier knows how old you are at all times. It knows this because it knows how old you aren't. By subtracting how old you are from how old you aren't, or how old you aren't from how old you are (whichever is greater), it obtains a difference, or remainder.

Partner: You might log into BlueSky and post pictures of your rack.
A high-angle shot captures a black 15U open-frame server rack with casters standing on a wooden floor. Behind the rack, framed perfectly by its rear face, is a cardboard box with a 4U server chassis (cover open) resting on it. The open chassis reveals internal components, including a Mini-ITX motherboard, several beige and brown Noctua cooling fans, and, notably, an empty PCIe slot. The front of the chassis has a dense array of hot-swap bays, including thirteen 3.5-inch bays, two 2.5-inch bays, and a single optical drive bay. To the left of the rack sits a speckled stool, and the background includes exercise equipment, a VR headset, scattered tools, and a bunch of hard drives.

I mostly share this sentiment, but what I really want is to be recognized as nonbinary. I do get spontaneously referred to in a gender neutral way fairly regularly.

The 12th annual international Gender Census 2025 is now open until at least 30th August 2025! survey.gendercensus.com It's for anyone whose gender (or lack thereof) isn't described by the M/F binary. It's short and easy, and results are useful in academia, business and self-advocacy.
Title: Gender Census 2025.

Text: If you can't easily put yourself into just one of these two boxes, you are invited to take part.

Illustration: Two boxes, each with photos of relevant dictionary pages.

I had a simple goal: dump the MAC address forwarding database from a "Web Managed" PoE switch. It has SNMP, but of course it doesn't expose that information. Fine. Violence (scraping with a Python script) it is. I should have known this would not be straightforward.
