    You can/could also find Coffee HOWTO in your distro’s HOWTO package. (I found a reference back to v0.5 of the document in 1998.)

    Has simple schematics to get you started for the hardware, using the parallel port to toggle relays.

    It’s a very neat little document, and inspired me to write a simple kernel module so I could echo 1 | sudo tee /sys/whatever/coffee0 to turn pin 0 high on the parallel port. (This is silly, and it’s much easier to just do things in user space!)







  • Cool, I recommend it!

    I have my public facing reverse proxy point to my public services, and I also have it set up as a “roadwarrior” VPN to my home. So, I can connect my phone via WireGuard to my VPS, and a local DNS resolves my private services to the private IP addresses in my home network (so, I also run a reverse proxy on my server, for internal services).

    I also have an off-site backup using this — just a raspberry pi and an HDD at family’s, that rsyncs+snapshots over the WireGuard network.

    I’m sure I’m not following all the best practices here, but so far so good.





  • I switched to Technitium and I’ve been pretty happy. Seems very robust, and as a bonus was easy to use it to stop DNS leaks (each upstream has a static route through a different Mullvad VPN, and since they’re queried in parallel, a VPN connection can go down without losing any DNS…maybe this is how pihole would have handled it too though).

    And of course, wildcards supported no problem.




  • "While I’m up here I want to shout out all of our friends and neighbors who couldn’t be here tonight. Our international friends and neighbors who cannot safely travel to this country. Our immigrant friends and neighbors who cannot safely travel inside this country. Our trans friends and neighbors who cannot safely travel after having their driver’s licenses revoked overnight without warning by a cruel and unnecessary legislative act.

    “Our friends and neighbors in places like Iran, Venezuela, or Gaza who fear for their lives on a daily basis because of cruel and unnecessary violence. I don’t have any plans to stand on this stage again anytime soon, but if I ever were to do so again I would want it to be amongst all of my friends and neighbors, safe and thriving.”



  • At this point, they no longer obey the laws of classical physics, and the resulting quantum phenomena — known as relativistic effects…

    This is…not how I would word things. Atomic physics is usually not in a classical (Newtonian) regime, and a quantum treatment is standard.

    Adding relativistic effects to the quantum treatment is also standard, but many aspects of e.g. the hydrogen atom are reasonably well described without relativistic effects, though of course relativistic effects do matter.

    Nitpicking aside, neat stuff!
