  There are many good books and resources on Z80 Assembly but this programming tutorial by Patai Gergely is valuable for a couple of reasons. Gergely last worked on this in 2004 when people still cared about good work. And it covers material beyond the basics such as simple data structures and programming techniques. The tutorial is available as a website: https://tutorials.eeems.ca/Z80ASM/index.htm and a single PDF that includes all the pages on the website: https://element.zxfiles.net/DOCS/A...

  I didn't know Kermit was so advanced and versatile as I used it little back in the day. The venerable file transfer protocol, which turns 45, is also a great story of old school, non corporate open source. https://changelog.complete.org/archives/44456-celebrating-45-years-of-kermit-with-the-first-new-c-kermit-release-in-15-years-and-working-with-a-decades-old-c-codebase #kermit #protocol #retrocomputing #foss

  Back in the day I didn't know much about the Andrew Project at Carnegie Mellon University. This 1996 retrospective, by one of the lead designers, is also a good history and overview of the main components: a network file system, a GUI toolkit, and an email and bulletin board system. https://dl.acm.org/doi/pdf/10.1145/272682.272717 #AndrewProject #cmu #retrocomputing

  Just a reminder that it helps to thumb-up this issue to request support for Mastodon post migration. It was opened in 2019 and my hope is the @MastodonEngineering@mastodon.social team will notice the feature is highly requested and bump the priority a bit. https://github.com/mastodon/mastodon/issues/12423 #mastodon #fediverse

  The TMode Lisp library is interesting for both its features and its design approach. TMode is a library for creating text-mode user interfaces in Common Lisp. [...] By design it is a zero-dependency library, no ncurses, cffi or anything required. https://codeberg.org/fourier/cl-tmode #CommonLisp #lisp #TUI

  This is Medley Interlisp running the Lafite email program. The mailbox window at the bottom left has a single entry, a test message I sent myself shown in the large window to the right. What's neat is Lafite delivered to and retrieved the message from a mail server by exchanging packets over the Xerox XNS local network, here emulated with the server on my Linux box via Dodo Services. See the network logs in the black Prompt Window at the top left. Nick Briggs @nhbriggs is reviving the orig...

  Why Joe prefers a Lisp dialect over Haskell as his default programming language. Scheme (and Lisp in general) might lack Haskell’s innovations and purity, favoring a minimalistic flexibility instead, but it mixes practicality with functional beauty in a way that makes it a functional language for human beings. https://jointhefreeworld.org/blog/articles/lisps/why-i-still-reach-for-scheme-instead-of-haskell/index.html #lisp #scheme #haskell
