Burning Mesh is a volunteer-run, off-grid LoRa mesh network for Burning Man — works without cell service or WiFi. Last year there were around 1,700 nodes on the playa, which is dense enough that they had to build custom firmware just to keep the mesh usable. The 2026 firmware went live recently. I'm just planning to join with a couple of nodes myself, not involved in building it. Hope to see y'all at the burn!

Great video, thanks for posting. Since Meshtastic keeps coming up in the video — if anyone here is heading to Burning Man, there's a dedicated mesh network for the event. I will have a couple nodes running on it :)

It is a"replacement circuit board for the Casio 3208 module, used in the Casio CA-53W and CA-506 calculator watches" and very neighborly.

New comment by gourneau in "Making Postgres scale"

gourneau — Fri, 14 Mar 2025 23:13:13 +0000

I’m working with several Postgres databases that share identical schemas, and I want to make their data accessible from a single interface.

Currently, I’m using Postgres FDWs to import the tables from those databases. I then create views that UNION ALL the relevant tables, adding a column to indicate the source database for each row.

This works, but I’m wondering if there’s a better way — ideally something that can query multiple databases in parallel and merge the results with a source database column included.

Would tools like pgdog, pgcat, pganimal be a good fit for this? I’m open to suggestions for more efficient approaches.

Thanks!

Thanks for the Pigsty link. I have been a big fan of running Postgres on metal machines.

Here's hoping LLMs stick to the naming trend used for telescopes like the ELT:

• Large Telescopes → Large Language Models (LLM): Solid start, foundational capabilities.

• Large Telescope (VLT) → Very Large Language Models (VLLM): Major upgrade in size and skills.

• Giant Telescopes → Giant Language Models (GLM): Multimodal, smarter and more specialized.

• Extremely Large Telescope (ELT) → Extremely Large Language Models (ELLM): Expert-level, cross-domain.

• Overwhelmingly Large Telescope (OWL) → Overwhelmingly Large Language Model (OWLLM): Theoretical AGI, huge power, ethical dilemmas.

So far I have paid out of pocket, I have an insurance claim but I expect to at least max out of deductible.

If you are on Windows and have extra laptops of devices hanging around SpaceDesk https://www.spacedesk.net/ to a great free app (not open source). I use it with on my Windows Dev machine (WSL2 FTW) and use old laptops as external displays. It works well even on WiFI.

Thanks Eli! Almost 15 years ago learned a lot about Python GUI work from your blog. Some of your examples helped me write some software for NASA!

New comment by gourneau in "Ask HN: What's your experience with working M1 and M2 Macs?"

gourneau — Fri, 08 Jul 2022 23:18:44 +0000

I love my M1 for development, I have a work M1, and I like it so much I am getting M2 for person use.

I had 2 main issues at first, but they are both resolved. One, if you want to use arm native Python conda now supports arm which is great. The second issue was docker, but it turns out that docker has qemu built in. here is an example of how to use x86 docker images on a M1 Mac.

     docker run -it --platform linux/amd64 ubuntu bash
