“To the Finish” … and Beyond?

Can we continue to make computing devices smaller and/or faster?  Can we do this without limit?  If so, how?  What’s the next generation?

Microchip designers use a wonderful armoury of terminology, most of it (deliberately, one suspects) impenetrable to outsiders.  However, one of the – on the surface at least – least alarming, and certainly most charming, is the phrase “To the finish”.  It’s an intriguing term and behind it is the spirit of an admirable intention.  The only problem is no one really seems to know exactly what it means.

“To the finish”, in its broadest sense, is some mythological-technological future in which logic circuits have shrunk to such an extent that individual components are measured on the atomic scale.  On one level, although in nominally different research fields, this is comparable to the “intelligent dust” predictions of the most enthusiastic Internet of Things proponents.

Restarting Computing in UK Schools

A somewhat more down-to-earth post, this one; an overview of, and a case study in, the wonderful revolution in Computing and Computer Science currently taking place in British schools.  Adapted from a paper presented at the 4th World Conference on Learning, Teaching and Educational Leadership and published in the Elsevier ‘Procedia – Social and Behavioral Sciences’ journal.

The past few years have been challenging ones for Computing education in the UK.  After decades of national neglect, largely overlooked, from the county that invented Computer Science, there has been a sudden impetus to reintroduce computational problem-solving into the school curriculum.  Immediate obstacles include a generation of children with no CS background and a need for tens of thousands of new or retrained teachers.  The Computing At School (CAS) movement has been instrumental in this quantum transition from an IT to Computing syllabus, as have the British Computer Society (BCS), leading UK university CS departments and a number of major international technology companies.  This piece looks at the background to this position and the progress being made to address these challenges.  It describes, as an example of many, the work of the BCS-funded Glyndŵr University ‘Turing Project’ in introducing Welsh high-school students and staff to high-level programming and ‘computational thinking’.  The Turing Project uses an innovative combination of Lego NXT Mindstorm robots, Raspberry Pi computers and PicoBoard hardware together with the Robot C and Scratch programming platforms.

The Problem with ‘Futurology’

What’s your favourite terrible technological prediction?  There are plenty to choose from, that’s for sure.  The following is just a brief list of the most infamous computing-based futurology howlers (oldest to newest):

  1. “I think there is a world market for maybe five computers”, Thomas Watson: IBM chairman (1943) (* or was it someone else?)
  2. Computers in the future may weigh no more than 1.5 tons”, Popular Mechanics (1949)
  3. “I have traveled the length and breadth of this country and talked with the best people, and I can assure you that data processing is a fad that won’t last out the year”, Prentice Hall: Business Books Editor (1957)
  4. “There is no reason anyone would want a computer in their home”, Ken Olsen: DEC founder (1977)
  5. “640K ought to be enough for anybody”, Bill Gates (1981) (* or did he really?)
  6. “We will never make a 32-bit operating system”, Bill Gates (1989)
  7. “Spam will be a thing of the past in two years’ time”, Bill Gates (2004)
  8. “Next Christmas the iPod will be dead, finished, gone, kaput”, Alan Sugar (2005)
