Does computer #history interest you, or maybe you're just curious where well-known and well-used tools come from? I've just updated the History of #Unix #Manpages, https://manpages.bsd.lv/history.html, with the content you didn't know you wanted til this very moment. Learn about how the "man" program came to be, and just why are manpages styled like that? It includes snippets from Cynthia "Cindy" Livingston, who wrote the manpage language "mdoc"; John Eaton, who wrote the first GPL man tool; Doug McIlroy, who helped to divide manpages into sections; and more. Did you know that serving manpages online was part of one of the original http daemons? Or that an xman existed before X11R6, in X10? Enjoy!

btc price goes down -> not profitable to mine -> difficulty goes down -> not worth to attack

btc price goes up -> profitable to mine -> difficulty goes up -> not worth to attack

bitcoins price in usd has to double every 4 years to keep the hashrate (napkin math) which it easily did in the past. i guess you're assuming (based on what?) it won't in the future

the ponzi comparison doesn't hold structurally — a con requires returns to be impossible without new victims. bitcoin has a fixed verifiable supply, open-source code and a fully public ledger. early adopters benefiting most describes apple in 1998 just as well

i don't pressure or blame anyone for not owning bitcoin — i just see a lot of misunderstanding around it. and for what it's worth: mlms and cryptocurrencies are a scam. we agree on that

lower fees does not mean lower difficulty, there is not even a correlation, forget about a causation

I have a calculator that is correct 80% of the time. But don't worry, every time I use it, I check the results myself.

New #blog post alert!

I muse about research some of my grad students and I did around independently evaluating some #OpenBSD anti-ROP mitigations, and I bid farewell to being an OpenBSD developer.
