I spent many happy years making the Z80 dance, from Summer 1976 through Spring 1989, architecting and writing statistical multiplexors at MICOM Communications in LA. Micro 800 line. That is a Hard Real Time application, and the hardware for

My Lua system uses MOP too, though I never heard that term before. And structured pipes. I like it and wrote it for a dataflow bsased event driven system.

I still use a version of FORTH as an embedded debug tool, have done for several different CPU architectures over the years. I wrote some extensions that help to offset the "double edged sword with no handles" danger, such as local

I'll echo the observation: datacomms protocol parsing and generation are nothing but state machines.I started in that domain back in 1973 or so, and some configurations - statistical multiplexors for example - may be running upwards of

Forgive me, but I recall, with some decades of practice, a major point in FORTH is that one constructs a vocabulary and syntax specifically for solving the problem at hand. Compiler primitives are just as first class as regular word (aka fu

50 years. Somewhat different to most. Mixed hardware/firmware/software, niche talents matched to niche markets. And practically all self-taught. Along the way got a BS and most of an MS in CS but none of it was applicable to my ca

Native WinAmp has two dropin extension systems. The one everybody seemed to use was MilkDrop, but they also had AVS (Advanced Visualization Studio), for which I wrote a bunch of extensions about a decade ago. These included several composit

I used Lua 5.2 (with 5.1 compatibility enabled) to embed in a C framework for building and executing data flow graphs. I implemented C .h header to JSON and back, and also an API wrapper generator, which really helped things along. The basi

There is another kind of acoustic delay line that was used in late 50's - early 60's that used nickel strips and took advantage of magnetostrictive property of Ni. I'm calling it acoustic because the memory was in the form of

Hmmm. I created a system I called Sub-Machines back in the 80's too, though it never occurred to me that anyone else might be interested in it. I was particularly focussed on data communications protocol state machines. I could launch

I see they re-invented asynchronous logic, such as Chuck Moore's chip today uses, for their digital fabric.

Still have ny HP41C, with XMEM etc, but no longer carry it with me since i41CX came out for the iOS devices. Inludes all the rom extensions too. When I get the energy the system is for sale - printer needs new batteries, card reader needs T

100 ms max lag is maybe OK for human vision, but you need to be down below 25 msecs between action and accompanying audio, or between action and video and audio. The human ear is much more sensitive to the time domain than the eye. It'

Even earlier: I implemented a Statistical Multiplexor - 8 async serial users muxed over a single 9600 Bd synchronous line - on a Z-80 with 4K RAM and 4K ROM. In 1977. Garunteed correct data delivery over lines as noisy as 1x10^3 BERT. A dat

There was a lot of collateral damage too, small firms hitchng their wagons to FW tubed out, or pre-93 developing alternatives to USB for the same ends (just bad timing). It was up-front expensive, and while technically superior to USB addre

Correct me if I'm wrong, but I seem to be the only person here to have weathered the entire evolution from 8008 on, for a living not as a hobby (though is both for me). I am possibly approaching Senior Curmidgeon status, but I mean wel

We built relay computers in HS in the early 60's. There was this street in London: Lisle St, in the Soho district. One could buy surplus PO 3000 multi-pole relays there real cheap - up to 10 pole IIRC. These were the relay type used on

The issue becomes really serious when playing 96 audio files simultaneously. As in: game audio or multitracking DAW (where 24 or more would be recording at the same time, not merely playing back). Every cycle counts there, any cycle not mov

Audiobus provides State Saving, have you tried that? Feed it into AUM for IAA, AU, and their state gets saved, plus the routing and mixer setup.

Not watched the video, but hate to tell you, they are designed by visual thinkers. Linearization comes after the fact; one has to be able to visualize the operation of the logic networks etc during the design - and debug - processes. Things

Actually there is, in the (stated in the movie) supposition that what you can think about is bounded by the language you think with. Corr.: learn a different langauge, change how your brain processes your experience. So learning Heptapod ch
