Ciro Santilli distinctly remembers being taught that at basic electrical engineering school during Ciro Santilli's undergrad studies at the University of São Paulo.

It really allows you to do alternating current calculations much as you'd do DC calculations with resistors, quite poweful. It must have been all the rage in the 1950s.

RSA vs Diffie-Hellman key exchange are the dominant public-key cryptography systems as of 2020, so it is natural to ask how they compare:

As its name indicates, Diffie-Hellman key exchange is a key exchange algorithm. TODO verify: this means that in order to transmit a message, both parties must first send data to one another to reach a shared secret key. For RSA on the other hand, you can just take the public key of the other party and send encrypted data to them, the receiver does not need to send you any data at any point.

TODO what's the point of it.

The only reason why Ruby exists.

This web framework is pretty good as of 2020 compared to others, because it managed to gain a critical community size, and there's a lot of basic setup already done for you.

it is just big shame it wasn't written in Python or even better, Node.js, because learning Ruby is completely useless for anything else. As of 2020 for example, most Node.js web frameworks feel like crap compared to Rails, you just have to debug so much there.

Used in GitLab, which is why Ciro Santilli touched it.

Cirists,

This month included several exciting extremelly user visible web developments.

I can't help to feel how the speed of developments reflects my relative mastery of the stack, I'm very happy about how it went.

Naming taxonomic ranks like genus, domain, etc. is a fucking waste of time, only useful before we developed molecular biology.

All that matters is the tree of clades with examples of species in each clade, and common characteristics shared by the clade.

And with molecular biology, we can build those trees incredibly well for extant species. When extinct species are involved however, things get more complicated.

One of the first big interpreted programming languages to go a bit further than Bash' word replacement insanity.

To the modern viewer, it feels like a middle ground between Bash and Python.

It was completely insane however, and it just died: Python is much saner, and Bash, although totally insane still golfs better, especially on the file manipulation context.
