You're Magnetic Ink...

"In the beginning was the command line" was the title of Neil Stephenson's 1999 book comparing various computer operating systems of the time. Of course, the reality is somewhat different: in the beginning there were no operating systems at all, just machines hand-coded by whatever means were available: hard-wiring, switches, and later, paper tape and so on. The layer of abstraction between machine and programmer that is an operating system first kicked in in the 1950's, and the idea of a command line really only started when suitable input/output devices came about. 

The input modus operandi for many years owed much to the tabulating machines that preceded the general purpose computing machine: the punched card, which itself had its origins in the 1804 invention of the Jacquard loom, where cards perforated with a carefully arranged matrix of holes controlled the weave in the eponymous loom. On the output side, the ubiquitous method until the 1970's was the teletype: first the physical paper & ink machine, replaced initially by the Virtual Teletype - still actually extant as a family of video terminals, starting with DEC's late seventies VT-100 - that were all eventually superseded with the explosion of 'modern era' operating systems that all started with command line interfaces, which in turn developed into the sophisticated working environments that we now take for granted.

But I agree with Neil Stephenson in one regard: what we have now essentially started with the original CLI's (command line interfaces) like DOS and which are still with us in all the UNIX/LINUX variants and the systems (e.g macOS) whose fancy GUI's (graphical user interfaces) are larded on top of. My late friend Jean-Charles always preferred the command line for many of the more routine daily computer tasks: email, installing/uninstalling software, etc. The latter functions I too feel are easier via a terminal than otherwise, and the lack of clutter, directness of response and spartan elegance of the CLI is particularly compelling to those of us of a certain mindset; although as a generalised replacement for a modern GUI? Not a chance.

    Sat and used one of these back in the day, late 70's I guess. Lucas had a pile of DEC equipment.

Of Feedback & Wobbles

Many years ago I came up with an analogy for poorly damped feedback loops. The feedback loop that prompted this frankly tart analogy was indeed a horror. Anyone who remembers shame-faced their first attempts at clutch control resulting in the good old kangaroo launch across the lights only to stall in the middle of the crossroads will have some idea of the kind of data transfer lag involved in said system. The analogy I made was that of a large blancmange. Untouched, a model of stasis and eminently stable and predictable; but prod the bugger and the resultant chaotic behaviour needs a very complex physical model and some very decent computing horsepower to predict its outputs, if at all. The system in question was a large and complex audio-visual display at what eventually became 'The Electric Mountain' in Llanberis. We were ultimately contracted to maintain the thing having been witness to and peripherally involved in its installation. Certainly not involved in its des

Sister Ray

Ray Keats - aka Ann Key - local artist & family friend, died this morning. She'd been ill for some years, but never let it get in the way of her work or of tending to the massive network of friends, colleagues and fans she had accumulated over the decades. Her house on the High Street of Rachub, just below where we live - a former cockle factory(!) - bought many years ago when she and her late husband Ronald moved here from Manchester to set up home in Yr Achub, is currently still home to her paintings and drawings, and the front window displays her work, including the last drawing she made in hospital, just days before she died. Her good friend Colin has been a diamond in her latter years, looking out for her and just being there when she needed him. She will be much missed by this tiny community of ageing bohemians up here in the hills, but suffice it to say, George, her cat, will be well looked after now she's gone.

A Time of Connection

I was just reflecting on the vacuum of continuity that's left behind when someone dies: that sudden sense of disjoint, of fracture, in one's personal history that takes one completely by surprise at the oddest moments. These pinch-points in memory can often yield some surprising revelations of fact about periods in one's past. One such occurred to me tonight, tending my rather lazy meal of pizza in its journey from shrink-wrap to mouth via the oven. Al's recent demise still catches me out from time to time: the space he left bounded by forty plus years of friendship. But the thing that struck me tonight was just how much change was happening on a personal and social level in the very early years of our acquaintance. Between moving here from Birmingham in September 1980 and our buying our first proper house eighteen months later, all manner of things occurred that would chart the course of our lives to the present day. At around the time of our meeting Alan & Irene [
