Oh man I have to try this on all the legacy Fortran nuclear reactor simulator codes originally written in the 1960s

This is the type of fuel planned for the TerraPower Natrium reactor and also the Oklo sodium-cooled reactors.

Interesting stuff.

How many tokens/second you getting? I have the same CPU but a 5070 and only 64 GB of ram. I just got llama.cpp built and am now hitting a whopping 5-6 tokens/s.

LFTRs make readily-available (liquid-form) weapons-grade Uranium-233 during protactinium separation. They're the least proliferation resistant reactor known to man.

LFTR has a far larger core than a PWR. Neutron diffusion length in water is 5 cm. In LFTR graphite moderator it's 16.

Many reactors including modern SMR LWRs can cool themselves passively without backup power. Especially when floating in seawater.

Highly recommend doing PWRs for this application.

Disclaimer: I'm trying to do this with PWRs.

Frigate is so amazing. The lightweight object detectors plus home assistant automations and notifications are way too fun and powerful. I keep setting up new systems for family members after they see mine.

Their FAQ says they use Public Domain Registry to actually buy the domains. They are a wholly owned subsidiary of The Endurance International Group, who is owned by Clearlake Capital, a PE firm! So while it may shield you a bit, if you're moving from namecheap just to avoid PE then that may not be the most obvious choice.

I spent a long time recently setting pretty much this same thing up. When in my office my Android phone battery rapidly died, I guess because usteer kept trying to steer it or something. I ended up turning off usteer and 802.11r and just deal with slow roaming. Maybe I should try again with the static neighbor reports.

I always find this sentiment curious for 2 reasons:

1. Radioactive waste gets less toxic over time unlike many toxins like mercury, lead, and cyanide. People seem to emphasize the duration of toxicity for radiation while apparently giving 'forever toxins' a total pass.

2. Short-lived radiation is what's really dangerous. When atoms are decaying fast, they're shooting out energy that can cause real damage fast. Longer-lived radioactive stuff with billion-year half-lives like natural uranium can be held in a gloved hand, no problem. In the extreme, and infinite half life means something is stable and totally safe (radiologically at least).

Yet people still want to emphasize that radioactive byproducts of nuclear power have long half lives. I don't really get it.

This is often used within the industry to mean many dozens of commercial nuclear power plants.

New comment by acidburnNSA in "Apocalypse Early Warning System"

acidburnNSA — Fri, 01 May 2026 20:14:43 +0000

I made something like this in like 2007 called Apocalypse Feed. It took in a few factors and aggregated them into a 0-to-100 number that updated and published over RSS. First it pinged debian mirrors around the world and made a map based on mirror city's lat/long: green for online, red for offline. If there was a cluster of red, that part of the world was considered gone. Then it checked space weather data and nearest asteroid, increasing the value if it was looking bad. It scraped news headlines looking for key words like zombie, pandemic, virus, war, bomb, etc. These fed into a pie graph showing what "type" of apocalypse was most likely at any given time.

It was all fun and games until my VPS host banned me for pinging too many people every few mins.

I don't use it and so haven't compared. I'm interested as well.

Tangentially related, I recently had some hand-me-down high-end full tower speakers lose their integrated subwoofer amps. I bypassed them and wired in an external amp but people said the integrated DSP would be missing. That's when I learned about CamillaDSP [1] and CamillaFIR [2]. I got a calibrated UMIK-1 microphone and did a frequency sweep in the room. Then I applied the Camilla-computed FIR filter to my snapcast-sourced music stream on the Raspberry Pi 3 B I have networked into the living room. Now I have room-corrected and loudspeaker corrected fancy DSP and the speakers sound better than ever. Pretty fun, and very cheap. The Pi3 runs it using about 20% of its CPU. Not bad! I did the same process up in my office with some desk speakers and they sound great too (that time using EasyEffects to apply the filter in real-time rather than CamillaDSP).

I did a book in rst and liked that it had cool admonition, import, glossary, and index features that made it better than markdown for me. Still hate the heading conventions.

On the plus side, mine misdetected a wake word during a funny conversation and said "Sorry, I can't find any area called _____[60 second repeat of funny conversation]___" and it made my family laugh harder than we've laughed in a really long time. I even went into the tts cache and saved the wav b/c it was sooo funny.

Ryzen 5950x cpu, 64 gb ecc ram, dual 16 tb drives for zfs, Nvidia 5070 gpu.

Way way overspeced for what I listed, but I use it for lots of video processing, numerical simulations, and some local AI too.

I have a similar subset of this stuff running at my mom's house on a 16 GB ram Beelink minicomputer. With openvino frigate can still do fully local object detection on the security case, whish is sweet.

acidburnNSA — Sun, 08 Mar 2026 17:54:11 +0000

I have something like this, in the same case. I have beefier specs b/c I use it as a daily workstation in addition to running all my stuff.

* nginx with letsencrypt wildcard so I have lots of subdomains

* No tailscale, just pure wireguard between a few family houses and for remote access

* Jellyfin for movies and TV, serving to my Samsung TV via the Tizen jellyfin app

* Mopidy holding my music collection, serving to my home stereo and numerous other speakers around the house via snapcast (raspberry pi 3 as the client)

* Just using ubuntu as the os with ZFS mirroring for NAS, serving over samba and NFS

* Home assistant for home automation, with Zigbee and Z-wave dongles

* Frigate as my NVR, recording from my security cams, doing local object detection, and sending out alerts via Home Assistant

* Forgejo for my personal repository host

* tar1090 hooked to a SDR for local airplane tracking (antenna in attic)

This all pairs nicely with my two openwrt routers, one being the main one and a dumb AP, connected via hardwire trunk line with a bunch of VLANs.

Other things in the house include an iotawatt whole-house energy monitor, a bunch of ESPs running holiday light strips, indoor and outdoor homebrew weather stations with laser particulate sensors and CO2 monitors (alongside the usual sensors), a water-main cutoff (zwave), smart bulbs, door sensors, motion sensors, sirens/doorbells, and a thing that listens for my fire alarm and sends alerts. Oh and I just flashed the pura scent diffuser my wife bought and lobotomized it so it can't talk to the cloud anymore, but I can still automate it.

I love it and have tons of fun fiddling with things.

Yeah, but autofilling everything down to the neighboring city is still a huge improvement.
