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

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

  • 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.






  • 99% of the time it is just automatic and part of the update. Usually it’s only an issue if you are updating from a specific older version of something or have made a particular customization that breaks with the update.

    Like others, I’ve got at least one system running Arch for 10+ years and I’ve only had to manually do something a handful of times. Usually it’s just that I have to update the keyring first before the rest of the update.



  • 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.
