> Its a bit more complicated than that. For starters immunity doesnt identify all parts of a virus. It only identifies parts of a virus that have a binding site on it. As far as i know thats just the spike protien for covid but i may be wrong.

for covid there are at least spike- and nucleocapsid-proteins for which antibodies are created.

> As for immunity leading to reducing the attack surface, thats very much a myth that keeps circulating and its more complex than that. Studies show that when you introduce vaccines, or natural immunity, but do not approach herd immunity that you increase the chances of variants evolving. Therefore immunity is only effective at stoping the virus effectively id herd immunity can be reached first. So the two factors at play is the mutation rate of the virus pitted against the time it takes to approach herd immunity. Coronaviruses tend to evolve relatively quickly and as such its unlikely we could reach a herd immunity before it triggers a new strain.

i meant herd immunity by "attack surface", yes. i think with the current vaccines we can't win the race as immunity wanes too fast (like you've wrote), it might would have been better to roll them out only for at risk groups to reduce the risk for selection around the vaccine. this point is moot though.

> Finally while you are right the new strains are not going to necessarily evolve towards being more deadly, they also arent neceseraly going to evolve towards being more silent. More often we see it evolve to be more contagious earlier in the infection leaving it to be as deadly as it "wants" to be later in the infection. Many viruses kill or disable you, or show symptoms at all, only after the most contagious part of their life cycle.

agreed! i just think it's the worst FUD i know if the WHO president says "deadly as ebola" about the omicron variant.

For those of you who enjoyed my recent blog post on Circuit Duals and Magnetic Circuits I have now compiled a version of it in PDF if you want to keep a local copy or have it for reading on on an e-reader. Feel free to distribute the link.

For those of you who are just now hearing about it the article describes the idea of Duality in math, how it applies to circuits, how to calculate duals for systems of equations, and a few examples of circuit duals. It also goes indepth on magnetic circuits as a dual of electric circuits. There is an interesting blurb at the end about how to extract energy from permanent magnets as well.

If you prefer the more colorful blog link instead, which will also be the only place I make corrections or update it most likely, the link for that is as follows:

So two weeks working on this article about Circuit Duals and Magnetic Circuits and it is finally finished and published! Check it out!

Its about mathematical duals and how they relate to electric circuits. I cover several common circuits as duals and how to calculate duals. Bu I also describe a rarely known type of circuit dual called a magnetic circuit that uses the magnetic field instead of an electric field to do all the things an electric circuit can do and explain magnetic inductors and capacitors. It's pretty cool stuff, I even touch on how you can extract energy from the magnetic field of a permanent magnet to power a magnetic circuit (or an electric circuit for that matter.

@notresz @freemo runs qoto.org has always given helpful and useful information with his broad range of interests

@p is also a very cool guy, runs FSE and, from my naive understanding, clued up in all things opsec and computing

they might not like being mentioned in the same breath but they're "big nodes" in fedi imo

Also worth checking out bitcoinhackers.org and others on qoto.org

strong shitposting/memework on FSE but I wouldn't expect tech insights from the majority there ;)

In 1930 the Indiana Bell building was rotated 90°. Over a month, the structure was moved 15 inch/hr, all while 600 employees still worked there. There was no interruption to gas, heat, electricity, water, sewage, or the telephone service they provided.
