Found a beautiful article via @esteban (thanks! it is amazing) on how the #vaccine from #Pfizer works, I will try to summarize here in a thread. #SARSCoV2 #COVID19 #PfizerBioNTech original source is: berthub.eu/articles/posts… Vaccine idea: Synthetic mRNA is injected to us, gets processed by ribosomes and starts producing the protein mimicking the virus in the cells that our immune system will use to get immunity for the real virus. RNA is better since RNA is the pure “working” structure of the virus.

"Exploring different infinities" (since @mauropm & @gnuowned) told me they did no understand when they invited me to their podcast @openenchilada).

The idea of this thread is to show you easily that there are different infinities [...] #mathematics #mathschat #math #maths Lets start with the set of natural numbers IN={1,2,3,...} the size of this set is ℵ0 (aleph-0) which is the first infinity. We want to compare this infinite set with others. But first, how do you know when a set A has the same size as a set B without counting? [...]

What’s today’s hacker-generation learn path? (Thread) “In my times” we were good at C/Python, wrote exploits with its shellcode using gdb/olly to reverse, we read books on #algorithms, unix internals, protocol design and RISC architectures were beautiful. Regex was a most. (1/1) I remember reading books of Knuth “art of computer programming”, Cormen’s algorithm design, the old C programming by Kernighan, Unix Internals. Moreover we were into OS design, I used to have a SGI fuel to experiment with schedulers/kernel in IRIX on MIPS64, SPARC and other (1/2)
