Check out my open source game engine! https://strayphotons.net/ https://git.sw0.com/frustra/strayphotons

I have been developing this engine on and off for over 10 years, and still have big plans.

  • This whole blog seems extremely pro-AI and their entire site is full of articles supposedly debunking why data centers aren’t actually bad after all…

    This specific article has some pretty crazy conclusions about Benn Jordan’s own double-blind study. They’re saying it wasn’t double blind because he might have noticed water shaking, but in the actual video he explicitly says he threw out any of the data points where he knew if the sound was on. The results seemed pretty conclusive to me.

    The other thing is it talks a ton about wind turbine infrasound, and how dangerous levels are thousands of times louder. But the actual measured level of sound ARE thousands of times higher. Measurements have been taken at 96dB, which is significantly higher than the 50-75dB this article is referencing as safe. If the 96dB infrasound is loud enough to shake a glass of water as above, it’s not “imperceptible” like the safe levels.

    As with all loud sounds in general, exposure time is a factor. A brief burst above 100dB won’t damage your hearing, but extended exposure will. I don’t see why the same wouldn’t apply to infrasound. All these studies are 72h or less of exposure, but there’s people living next to these datacenters 24/7.

    Personally I’m waiting for more research to be done. There’s not enough data to be calling things fake or debunked here.












  • Unless they’re on the ground floor, there’s a lot more to consider than just the compressive strength of concrete. If the gold is sitting on a concrete beam, it bends, causing the bottom to be in tension, while the top is in compression. Concrete has really terrible tensile strength, so rebar is installed to keep it together. The load limit of a concrete beam will be significantly less than that of a solid concrete pillar, and depends on the engineering design.

    Most of the heating energy would actually be IR, which many types of window glass will be designed to reflect. It probably depends on what kind of coatings are used. Basically all car windows block IR to help keep the inside of the car cool in the sun.







  • Sounds like my homelab has better redundancy than these guys, and my monthly bill isn’t much different than their new one. I only pay for power and networking, since I own my own hardware. I’m colocating in my city, so my latency to home is about 1ms, and I’ve got a full mirrored server in my house. Certain files are further backed up elsewhere for proper 3-2-1 backup (+ each server running raidz2 with disk encryption). Even if my home Internet goes out, I still have full access to my files at home, and all my public services stay running in the data center. If either server fails, it’s all set up with containers so it’s easy to spin up each service somewhere else.

    One thing that’s tricky to get right with disk encryption (especially with encrypted /boot) is having a redundant boot partition. I was able to hack this together by having sofware raid duplicate my boot partition to a second drive. Now if I remove either OS boot drive it falls back to the remaining one. To prevent breaking EFI boot, you need to use the Version 1 RAID format so the metadata is stored at the end of the partition, not the front where EFI reads.
