The Solaris `snoop` command for capturing network packets has supported a -a option for at least 20 years which listens to packets on /dev/audio and comes with a warning that it "may be noisy". It used to be fun to run o

This is a good intro and really highlights how Rust doesn't have a learning curve, it has a cliff. I'm tackling this in my own book [0] because I think the docs really throw you in the deep end (mixing metaphors). As this article

Senior level positions in Europe often come with a 6 month notice period, so it's not even really possible to job hob that often. There is a strong preference for stability and continuity of leadership.

I feel like this is missing any mention of the history of KV stores. Unix came with an embedded database (dbm) from the early days (1979) [0] which was rewritten at Berkeley into the more popular bdb in the 80s. [1] Sendmail was one of the

I remember learning about filesystem design from the classic "demon" book (The Design and Implementation of the 4.4 BSD Operating System by Marshall Kirk McKusick) which has a lot of details about the original Fast File System.

Yes! I use the (final) 4.4 release from 1993. Some were written by Bill Joy! But if you look at the modern OpenBSD or FreeBSD (or MacOS) versions they’re still about 90% unchanged. The older versions are a bit shorter which makes it easier

I'm self-publishing "Rust From the Ground Up" which takes this approach: each chapter rewrites a classic Unix utility (head, cat, wc, ...) from the original BSD C source into Rust. I find for systems programming it's eas

One of the reasons that NFS was so popular is that Sun gave away the protocol implementation. It's really interesting to see the technology behind that though. The whole protocol (both versions 2 and 3) is defined in a single file.[0]

That's the classic solution but blows up when using multibyte characters since rev just reads the bytes in each line in reverse.
