@amoroso 👆 My new Mastodon account is @amoroso@oldbytes.space and I'm initiating the migration to Oldbytes. See you in a few hours.

I decided to migrate my Mastodon account from Fosstodon to @amoroso@oldbytes.space over the next few hours. For more context see:

https://kevquirk.com/blog/my-thoughts-on-the-fosstodon-drama

https://coreysnipes.com/thoughts-on-fosstodon.html

Given this, I sincerely hope the instances that plan to defederate Fosstodon will delay by a few days to allow people to complete migrating.

This 2019 Mastodon feature request suggests supporting post transfer when migrating to a different instance. If you'd like such a feature (I sure do) consider thumbing-up or reacting to the issue.

Thanks @tokyo_0@mas.to for the reminder.

Support Post Migration · Issue #12423 · mastodon/mastodon

#177 – Support Account Migration – was closed after implementing follower migration, but this is only one small part of a true migration. To really be able to change instances, you need to be able ...

@sgharms@techhub.social Glad you made it, it looks good. Maiko also has FreeBSD build scripts and works on Wayland (likely via xwayland) as it doesn't do anything too esoteric.

@sgharms In addition, Medley is pretty much Lisp all the way down. Nearly every single piece of the system, from the lowest to the highest layers, is Lisp and can be accessed/called from Lisp (eg at some point the full TCP/IP stack was written in Lisp). Whereas on Linux you have a shell language, compilers for various languages, more languages in your web stack, and so on. There's little or no interoperation and data sharing between these languages and the processes they run in.

@sgharms Here I opened an editor to modify the system function (think kernel, window system) that creates a window, CREATEW. See the dumb comment near the end. I could, say, add some logging code, recompile (just the function, not the whole system), and have the new behavior instantly running in the updated system at the next window opening.

@sgharms 2 Yes, that's more or less it. Medley is as if you could call or access a single piece of the kernel or a running program from the shell or other parts of the system (the Firefox example in 1.).

@sgharms 1. Back then Medley offered what now we consider a full desktop distro like Ubuntu or Fedora, not just a minimal one with X and twm. Medley offered OS kernel, window system, network stack, print manager, Lisp interpreters and compilers, Lisp libraries, debugger and dev tools, applications (eg word processor), and more. Everything had a public Lisp API or could be called and accessed from Lisp, down to the individual function (think calling a single Firefox C++ function while it runs).

@sgharms If you mean a minimal Lisp OS, if it stayed up I don't think there would be much difference with traditional operating systems: the specific program would continue to run in the minimal Lisp environment. What's unique of a Lisp Machine environment is that the operating system, the development environment and tools, the programs under development, and the deployed programs run inside and share the same address space. Each of these entities can access, interact with & change the others.

@lopta I don't know whether PARC's Mesa provided 3D libraries but it's unlikely. @interlisp

@lopta Yes, Wirth did spend two sabbaticals at PARC and was inspired by the graphical environments being developed there such as Mesa, Smalltalk, and Interlisp-D. @interlisp

@interlisp 👆 The Medley Interlisp Project lands on the fediverse with the official Mastodon account @interlisp ran by yours truly. It's the beginning of a new adventure in Lisp and the history of computing you're invited to join. #interlisp #lisp #retrocomputing

The rise of the Web prematurely ended an era of active research and creative experimentation with hypertext technologies. In this paper @eastgate@c.im picks up where this era left off, and presents a neoclassical extension to embed web components in a classical hypertext system.

I'm having too much fun exploring NoteCards, the hypermedia system of Medley Interlisp. It provides a rich hypertext environment and tools as well as an extensive, easy to use Interlisp API.

This is a good introduction:

Common Lisp Quick Reference is a nicely designed, comprehensive, and handy Common Lisp cheatsheet. It's available in different PDF versions for printing as a booklet or online browsing, as well as LaTeX source.

PSW (Process Status Window) is an Interlisp tool for monitoring and managing "processes", which we now call threads. Here is PSW in Medley Online on my Chromebox, with the lower pane showing a function call backtrace of the selected process.
