I came across this article it-notes.dragas.net/2022/01/24/why…. I'm obviously biased, I hate what Linux has become (hey Lennart!), so I agree with most of the items. But I wonder if FreeBSD really still has better networking performance than Linux (out of the box, of course). Thoughts?


A very good case against crypto-currencies. Pretty much a mic drop. stephendiehl.com/blog/against-c…

The upcoming #FreeBSD #WireGuard kernel module seems promising: On a PC Engines APU2, the userland version reach 117Mb/s and the kernel version 483Mb/s. reviews.freebsd.org/D26137


An old article about TTYs. I remember having come across it in the past. Still this is the best one I know of and a good refresher to read. linusakesson.net/programming/tt…


Great blog entry written 6 months ago attempting to give an objective point of view on #Golang. Lots of things I have felt myself although most of the time feeling an annoyance without really taking time to think about it. bluxte.net/musings/2018/0…

The hash-bang directive '#!' is actually processed by the kernel: when a file starts with 0x23, 0x21 (which is #!) the kernel will interpret what follows as the path to executable and attempt to run. The message from Dennis Ritchie that introduced '#!' in Research Unix, Jan 1980

Article on "Surveillance capitalism". This is quivering: "It knows where we live, where we work, and where we spend our time, [...] when we wake up [and] go to sleep, who we sleep with. Uber used just some of that information to detect one-night stands." schneier.com/blog/archives/…


Everyone knows how to implement a naive hash table: a hash function, an array and linked lists. It works. But how would you change it to make it faster and consume less memory? Great talk about designing an efficient hash table for #Google. youtube.com/watch?v=ncHmEU…

Best article I've read on #Bitcoin split. It gave me a thorough understanding of the problem and what's at stake. arstechnica.com/tech-policy/20…


#Golang getting Generics 😂. (Not saying it should though 🤔.) qph.ec.quoracdn.net/main-qimg-dd2d…


Really good description of how #Bitcoin works. The best I've seen IMHO. youtube.com/watch?v=Lx9zgZ…
