It's the weekend, finally.

Linux Security Summit 🐧

Edited 1 month ago
A reminder that LSS-NA is happening a week from now in Minneapolis, MN!

Note that we have had three speakers withdraw due to circumstances beyond their control. We hope they are able to present their work at future community events, including LSS, where possible.

We've now added a Hackathon session on Day 2 (Friday May 22), where folk can work together in person on solving Linux OS security challenges of their choice. This could be for brainstorming, high-level design, PoC development, bugfixing etc. Utilization of generative AI is welcome.

As always, we will also have BoF sessions. Folk may also use these to make brief lightning style talks as appropriate, which may be useful for pitching new ideas or highlighting issues to the Linux OS security community. We've seen this work well over the past few LSS events.

🐧 See the current schedule here: https://events.linuxfoundation.org/linux-security-summit-north-america/program/schedule/

p.s. There are rumors of new LSS stickers being made available at the conference.

Doing a bit of a deep dive into 3D printing engineering filaments this weekend. Nylon + CF is a great all-rounder, it seems. Perhaps like how 6061 Aluminium is for metal fabrication.

Cool!

I've just been accepted to do a Build a lightning detector workshop at

I'll drag @Extelec to help out, of course :)

Playing with a Raspberry Pi 5, 4MB RAM. It’s been a few years since I looked at the Pi — my old one is a v2. These have come a very long way.

Reorganizing my home office & added a new switch to provide PoE and SFP. The latter is for steaming I/Q samples from mast-mounted SDRs for local processing. POE is for desktop IP phone (SPA525G) & SBC hacking.

Quite happy with this low-cost Linksys so far. 1990s me with a 10BASE2 net connected to a dial up modem would be astonished.

@ada Just struck me that this is the first photo I've seen of a woman beyond Earth's orbit.

Experimenting with 3D printed DIN rail mounts for projects. The attachment brackets are from open source hw projects, as are the WAGO & RS25 brackets. The PCB & vertical mount brackets are customized (to be published soon). I’ll adopt some kind of hole pattern standard for my own PCBs to simplify things. Possibly 20x20mm grid?

Transequatorial propagation (TEP) on 6m is strong today. It follows Earth's magnetic field lines for certain distances across the equator for complex reasons, allowing N/S America or JPN/AUS communication on VHF at times.

Protip: if you're chatting with an LLM about an idea that might be patentable, ask it about the confidentially status of your chat.
