"not a game" - well, he certainly hid this well behind a playful and enthusiastic way of teaching, as when he was our Props of Matter lecturing prof at Birkbeck College in the earl…

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…

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 …

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 - statistic…

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. Compile…

Started in 1967, in support of my job as commissioning technician (bean counter title - I was only 19 and no degree) at Elliott Brothers Elstree on their 4100 mainframe computers p…

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 …

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 ex…

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 w…

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 a…

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 …

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…

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 m…

"That which _can_ be configured _must_ be configured. Corr: defaults aren't. (mine, inspired by WIndows 1.0 and it's only got worse since).

7 am shift change. Unless you are my mon who had me at 11:30 pm.

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 cor…

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-…

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 possib…

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 …

There's an old iOS App called Vtrace been doing this for years. Interesting to see toures from my home to a destination 10 miles away bouncing all overr the country several times. …

thereby demonstrating just why she laughed. That R who yelled "Liar" at Obama? crickets.

creak. 69 here, still employed and coding etc, started in 1967, spent too many years having to make it up as I went along to specialize. If anything that specialty might be embedde…
