I started this blog on 11th August, 2014, which means it has been going ten years as of today. The idea was to write a kind of autobiography covering how life has changed in England since I was little.
The changes are many. After the war we still had ration books, bombed buildings, gas lights in the street, and Prefab houses. Later, in Leeds in the 1970s, my job took me to banks, building societies, manufacturers, merchants, shops, publishing and entertainment concerns, and businesses of all kinds that packed the city and further afield. Nearly all have gone. You could take evening classes in almost anything, and there were four or five cinemas in the city centre. The Leeds trams were no more, but sometimes I had to use the trolley buses in Bradford.
I then went late to university, which led to a new career near the edge of the computer revolution, and saw change as it took place. I suppose I played a small part in it. I also came late to having a family, which has been great fun. I wanted to write it all down.
There were few readers at first, but when I began to comment more on other blogs a few years ago, and chanced upon this friendly community, things began to pick up a bit.
At times during the last two-and-a-half years I thought I would not see this day. I was as good as told it, but I am still here. The next milestones are more fruits of the garden, my birthday, and then Christmas. And then we will be into 2025 and hopefully it all comes round again. Or will it? That sounds gloomy, I know, but it is what it is, and that is all there is to it.
It does not get easier, as my comment and response rates are beginning to show. The list of what I can no longer do, am not allowed to do, or would be stupid to try, is depressingly long. My reading difficulties make blogging slow and difficult, and I have thought of giving up, but it is one of the things that keeps me going, and I still have posts to write. I enjoy the exchange of humour, ideas, and opinions, reading what others have posted, and writing creatively. I am amazed others read it. Thank you so much, everyone.
Conservative governments are non-interventionist. They do not like the state to run anything. They spent the 1980s and 1990s selling off the country’s assets and giving away the proceeds. It continues today in their unwillingness to pay for public services or regulate things properly. Some of them would privatise health and education if they could get away with it. That is why, if my health holds out, I will not be voting Conservative at the next election. I will see the bastards* go to hell before I do.
And yet, in the 1980s, they did intervene. A 1978 television documentary, ‘Now the Chips are Down’, made clear how woefully unprepared Britain was for the silvery white heat of the computer revolution. It scared the Thatcher government so much that they funded a number of costly initiatives. Two in particular stood out for me.
In one, the BBC was recruited to raise awareness of the skills needed. It led to the ‘Computer Literacy Project’, which ran from 1982 to 1989. It was linked to the specially commissioned ‘BBC Micro’, which was taken up by many homes and most schools, with over a million sold.
In the other, the ‘Microelectronics Education Programme’, massive amounts of money were spent putting computers in schools, setting up and funding resource centres, and training teachers. Politicians boasted that Britain led the world in “equipping the children of today with the skills of tomorrow.”
Did it actually achieve anything, or was it bluster and spin?
At least it got my new career off the ground. After escaping from accountancy into a dream job as a university researcher, I knew as much about these new concepts and technologies as anyone. It would be hard to overstate how immersed, obsessed even, I was in this bright new world of colour and light.
I recently discovered that the television programmes, and more, are freely online in the ‘BBC Computer Literacy Archive’. It has the 1978 documentary which set things off (still informative 45 years later), and Dominic Sandbrook’s wonderfully evocative reflection on the social changes of the nineteen-eighties (not only computers). Incredibly, one programme even shows my own small part in this.
Watching again now, I am struck by how aware we were of the social questions posed by what was about to come. How would people spend their time in a world with less work? How should wealth be shared across society? It is not turning out as well as it might.
Most fascinating for me is the series ‘The Learning Machine’ (1985), about computers in education, the area in which I worked. Here, once again, are the names and faces I knew and discussed things with at workshops and conferences, such as the main writer and presenter, Tim O’Shea.
He was scathing of the Microelectronics Education Programme, which, he said, had foisted cheap, underpowered computers and poor software upon parents and schools. The attractive message about improving the quality of education, disguised what was really on politicians’ minds: the job market, supporting British industry, and making education cheaper. Eventually, we might even do away with schools and teachers completely.
The then ubiquitous programming language, Basic, comes in for particular criticism. It encouraged tangled, undecipherable code, leading self-taught home and school users to think they knew how to write software, when, really, their knowledge was badly lacking.
I think Tim was broadly correct, but we were all still trying to understand how to use computers in education, and few teachers had the skills to teach programming. I was taught structured methods and had no difficulty creating reliable, intelligible Basic programs several hundred lines long.
It can also be argued that the initiatives did have benefits, but they were two decades in the making. A generation of youngsters became fascinated by computers, seeding Britain’s successful computer games industry. So, perhaps it did work out well in the end. Tim did well too. He became Principal of the University of Edinburgh.
One other series caught my eye: ‘With a Little Help from the Chip’ (1985), about helping those with special needs. I was astonished, in programme 3, to see a one-minute clip of software I designed and coded, being used in a school for deaf children. I have written about the programs before, but never seen the TV programme. It brought back all the satisfactions of going into schools to observe and collect data.
Do you ever wonder, were it possible, whether you would happily go back to an earlier point in your life? I would, to this time for certain. And I would jump at the chance of another forty years. Most of all, it was an innocent, optimistic time, focused on what we were doing rather than the unrest and disruption taking place. We were trying to make the world a better place. We could do with more of that now.
* A name used by Margaret Thatcher for Eurosceptic right-wing Conservatives.
Writing in November about how careful we once had to be in saving and backing up our computer files, I remembered something else that was difficult: just getting information in or out of a computer. It happens now as if by magic: writing and reading stuff on smart phones, social media, Blogger, ... it is all so easy. We don’t have to think about what goes on behind the scenes. Most of us have no interest.
But, until the nineteen-nineties, computers were for nerds. As one of those nerds, I feel fortunate to have seen how things developed. I could still write programs to accept typed-in text, or to send a screen to a printer, but thankfully I no longer have to.
My desk at work in 1990
Back in 1970, computers were near-fantasies. Few had seen one except on television or in futuristic films: ‘Tomorrow’s World’ and ‘2001: A Space Odyssey’ come to mind. At work in accountancy, we had one client who used ledger cards with magnetic stripes, and there were golf-ball typewriters with primitive memory, but they were thought of as business machines rather than computers.
My friend, Neville, was the first I knew to latch on to the potential. He undertook a project as part of his business studies course, and that led to a job in the computer division of a Hull supermarket. This is the kind of thing he worked on: a system to help supermarket managers replenish stocks. They drew lines on forms that could be read by machine. It used forests of paper. The used forms (blank on the back) kept Neville and friends in rough notepaper for years; me throughout my university studies. They were great for lecture notes.
1970s Supermarket Stock System
Around this time, I took a job with a Leeds clothing manufacturer where account entries were made through yet more football-coupon forms. The forms went to a data centre to be coded on to punched cards and fed into “the computer”, which we were never allowed near. The data was printed on huge concertinaed sheets bound into weighty folders. Later, we all had to go on a course to be taught how to write numbers properly, in readiness for Optical Character Recognition which cut out the card punching part of the process. The weighty folders remained long after I’d left.
1970s Nominal Ledger System
Later, on a computing course, I learnt programming on
teletypewriter terminals connected to a mainframe computer. They printed
all your input and output on wide rolls of paper, and reprinted it all repeatedly.
These step-by-step exchanges continued after screens came in. Everything was
typed in as text and printed on to a scrolling screen. It even happened with games. I remember playing a version of ‘Star Trek’ in which you moved the ship by typing a location you wanted to fly
to, such as G27, and it dislayed and re-displayed your new position and
those of all the objects around after every move. The ease of Windows, icons, mice, pointers, and colour graphics were still a long time away, and touch-sensitive screens even further. Voice and gesture
input were not even dreamed of.
Not until around
1985 did we see the kind of systems we might recognise today, with
on-screen forms and menus. The first I worked with was written in DIBOL
and looked like this:
You could get quite excited about it. But, although it looked a bit like a modern windows system, it wasn’t. Every part of that screen is made up of text-like characters. It had to be planned out very carefully. Fortunately, not by me.
This system can be seen on the right-hand screen in the photograph of my desk at the top of this post. It was on a ‘dumb’ terminal connected to the DEC computer system. The screen on the left is an IBM business PC of that time, similarly unsophisticated. It was really something to be allowed two screens!
Just a few more of the things I kept. Like the old disks and tapes on the earlier post, they were used as teaching examples. They won’t be needed again.
New Month Old Post: first posted 4th January, 2017.
In 1978, Dr. Christopher Evans, a psychologist, computer scientist and expert on the future of computers, confidently made four predictions for the year 2000: (i) the printed word would become virtually obsolete; (ii) computer-based education would begin to supplant schools and teachers; (iii) money, in terms of physical bits of metal and paper, would almost have vanished; (iv) substantial and dramatic advances would have taken place in the field of artificial intelligence.
His only uncertainty was about the pace of change. It might take a decade or so longer, or occur more quickly, but the changes about to take place would be so stupendous as to transform the world beyond recognition. There would be more changes than in the whole of the two previous centuries. We were about to experience rapid, massive, irreversible and remorselessly unstoppable shifts in the way we lived.
Evans expanded his predictions in his book and television series The Mighty Micro. As well as the four main predictions, he thought we would soon see self-driving collision-proof cars, robotic lawn mowers, doors that open only to the voices of their owners, the widespread commercial use of databases and electronic text, a ‘wristwatch’ which monitors your heart and blood pressure, an entire library stored in the space of just one book, a flourishing computer-games industry and eventually ultra-intelligent machines with powers far greater than our own. Every one of these things seemed incredible at the time.
The social and political predictions were even more mind boggling. Evans foresaw a twenty-hour working week for all, retirement at fifty, interactive politics through regular electronic referendums, a decline in the influence of the professions, the emptying of cities and decreased travel as we worked more from home, and the fall of communism as underprivileged societies become astutely aware of their relative deprivation.
I remember how fantastic and exhilarating this view of the future seemed at the time, but it gave me a serious problem. Having escaped my previous career in accountancy, I was half-way through a psychology degree trying to work out what to do next. If Evans was to be believed, and I believed a lot of it, then most of the then-present ways of earning a living were in jeopardy.
What was I to do? The answer seemed obvious: something that involved computers. So like Evans, I looked for ways to combine psychology with computing, and after gaining further qualifications that is what I did.
Dr. Christopher Evans talks about educational software
It is fascinating to revisit Evans’ predictions. How many were correct,
what would have surprised him, and why? Many commentators conclude he
got more things wrong than right, but I am not so sure. The printed word
no longer predominates; computers now pervade education, albeit with
teachers in schools as guides rather than in the didactic and solitary way Evans imagined; and
nearly all significant financial transactions are carried out
electronically. And the less-bizarre predictions are already here.
Undoubtedly,
he over-estimated the pace of change, especially the emergence of
advanced artificial intelligence. Futurologists are still predicting it.
Stephen Hawking warned of the terrifying possibilities of machines
whose intelligence exceeds ours by more than ours exceeds that of
snails. On the other hand, it may still be as far away as ever. It
remains unclear what qualities such super-intelligence might have, or
whether intelligence might have an upper limit. Perhaps our inability to
imagine these things defines our stupidity. Where Evans was wrong, if it can be regarded as wrong, is that he was no seer. He could not escape the prevailing mindset of the nineteen-seventies, and foresee the innovative new uses of computers.
He did not foresee the internet. Multimedia crops up only in the form of a brief mention of “colour graphics”. Graphical user interfaces were still little more than a research project. He thought that electronic communications would take place through “the family television set” rather than personal hand-held devices.
And if you could not foresee these things, there is no way you could imagine how they would be used. Evans, with a seemingly naive view of human nature, imagined we would all be using computers to improve ourselves and make our lives easier; that our leisure time would be devoted to cultural, artistic, philosophical, scientific and creative endeavour of various kinds. I wonder what he would have made of internet pornography, fake news, selfies and cat videos.
Evans’ over-beneficent view of human nature coloured his vision of the social and political changes he thought would take place. Take the twenty-hour working week and retirement at fifty. The efficiencies brought about by computers could already have reduced our work significantly, but this has never been offered. It would upset too many powerful interests. Governments answer to the establishment more than the ‘man in the street’. As a result, for those who have jobs, the trend today is the opposite. And for those who don’t, wouldn’t it be fairer to share the jobs out?
Imagine if twenty hours per week up to the age of fifty was all we had to do. What would happen? For a start there would be those who decided to take on additional work in order to fund superior accommodation, private education, health care, better holidays, a more luxurious lifestyle and a more comfortable old age. Anyone content with just one job would begin to lose out. To keep up, we would all continue to work more than necessary, and the extra wealth would evaporate through increased spending, inflation and rising house prices, and disappear into the pockets of the elite minority, much of it overseas. Does that sound familiar? The only way to avoid the inevitable self-satisfied winners and miserable losers would be to ration the amount of work one could undertake, or the amount of wealth one was allowed to have. The necessary laws and financial penalties would be unpopular and difficult.
And how would we use our over-abundant spare time? One could easily imagine an intensification of social ills: epidemics of obesity, alcoholism, drug dependence, mental health issues and the breakdown of law and order.
‘Parkinson’s law’ prevails: work expands to fill the time available. Anyone with experience of large organisations will know how work once considered inessential or unaffordable, now occupies an entire additional workforce who administer quality, accountability and ‘political correctness’. Rather than reducing the overall workload, computers have increased it by making possible what was once impossible.
Stephen Hawking concluded his forewarnings about super-intelligent computers as follows:
“Everyone can enjoy a life of luxurious leisure if the machine-produced wealth is shared, or most people can end up miserably poor if the machine owners successfully lobby against wealth redistribution. So far the trend seems to be towards the second option, with technology driving ever-increasing inequality.”
Sadly, Christopher Evans died shortly after his book’s publication, three weeks before his television series was broadcast. It is often said that if you make predictions about the future the only certainty is that you will be wrong. Evans would have known this, but I suspect he would have been fairly satisfied by the extent to which he got it right.
My original post in 2017 was quite a lot longer and included links to the archived television programmes, so I have left it here. The programmes are fascinating to watch if this kind of thing interests you - the future as seen in 1978.
The way we save our computer files seems to have come full-circle, as if we are back to forty or fifty years ago.
Clearing out more of my life’s debris reminded me of this. I had accumulated a collection of disks and tapes that are now little more than museum pieces. You once had to be so methodical in looking after your documents and images. But, before that, it was all done for you. An so it is now.
At first, with mainframe computers, systems managers made sure everything was safely backed-up. I learnt to program in a room full of teletypewriter terminals - the noise was deafening - that were connected to a computer centre somewhere else on the university campus. Once you had typed in your program and asked for it to be save, you could be reasonably sure it would be there ready the next time you logged in.
However, if you wanted to move programs or documents elsewhere, or if you had one of those new-fangled micro-computers (i.e. a PC), you had to transfer it on to magnetic takes or disks. The first PCs had no internal disks, nothing was saved automatically by an ‘app’, and there was no OneDrive or Google. The internet did not get going until around 1995.
I learnt the hard way using Tandy TRS80 computers. Everything had to be saved on C60 audio-cassettes, which were notoriously slow and unreliable. I lost hours of work more than once. It was a godsend when floppy disks came along.
Here are some of the storage media I used, now destined for the tip.
8-inch floppy disks containing my Masters project, which was written in Pascal on an LSI-11 machine. UMIST insisted they had to be protected by special folders.
The 8-inch disks look enormous next to the later 5¼ -inch and 3½-inch ‘hard’ floppy disks you may remember.
This is a 6-inch cartridge take from a nineteen-eighties PDP11 Unix system, containing some of the work I did as a university research assistant.
Later, I used zip-disks which were a bit like thick floppy disks, but had greater capacity. Only a few home computers had them.
Then, we all moved on to CD ROMS and DVD, and USB memory sticks and SD
cards. I used a pair of memory sticks to transfer files from work-to-home and home-to-work. My first memory stick had a magnificent 256MB of space (that’s
Megabytes not Gigabytes).
How things have changed! Nowadays, some home computers have internet access only, and no disk drive or USB ports. Some have minimal internal storage. That is also the case if we work only on phones. It feels as if we are being pushed towards keeping everything on the ‘cloud’, like returning to the mainframe days.
Microsoft is removing the Windows video editor from our PCs (through Windows Updates) because they want us to use the online ‘ClipChamp’ editor. Google circulated an email saying they are deleting accounts inactive for more than two years. That could well include blogs. Andrew in Australia lost years of blog posts because of something unspecified he supposedly said. Next, they’ll be trying to charge us to store our stuff.
I don’t trust the b------s at all. I now have enormous amounts of material: family history research, my parents digitised photograph albums, our own photographs and colour slides, our own digital photographs, digitised videos from cine films, our own digital videos, ... and archived blog posts.
In all, it fills over 100 Gigabytes. I’ve backed it all up in duplicate on a pair of hard drives. I’m glad I learnt the discipline.
VAXen. It’s the plural of VAX. It used to say so in the DEC (Digital Equipment Corporation) computer manuals in the nineteen-eighties. VAX computers could be run as clusters of VAXen. Most universities had them.
A DEC 'dumb terminal'
So I was delighted to see some of these iconic machines again in Jim Austin’s Computer Collection
at Fimber near Fridaythorpe in the East Riding. By “again” I really
mean for the first time. Hardly anyone got near them in the
nineteen-eighties. The privileged might be allowed to look through the
glass of their air-conditioned rooms, but ‘users’ were never allowed in.
Their only contact with the computers was through remote ‘dumb
terminals’. At Fimber you can touch the machines and even open their
cabinets and take the boards out. Of course, they are not switched on
now.
He even has the first computer I used, the Elliott 903, not just any Elliott 903 but the very same one from the psychology department at Hull University. You really had to keep your fingers out of the way when the punched paper tape was flying through. What a sorry state it is in now. For a moment I imagined myself volunteering and getting it working again.
The Elliott 903 from Hull University, a punched paper tape computer
I returned home fizzing with enthusiasm, thinking of the blog posts I could write. My wife was not impressed.
“Great! A barn full of old grey metal cabinets. Fascinating!”
“Well, some of them are black. And you can open the doors and look inside.”
I babbled on excitedly about all the machines I had known so well: the
Elliott 903, IBMs, ICLs, PDP-8s and PDP-11s, SWTPC minis, LSI-11s, Sun
microsystems, Silicon Graphics, VAXen …
"Vaxen!" My wife ran out of patience.
“Did they come in boxen? Ordered by Faxen? Is our fridge Electroluxen? Cooling the milk for your Weetabixen? Vaxen makes them sound like little animals, or
the name of one of Santa’s reindeers.”
When my mother-in-law used to travel up from the South to visit us, and
passed through Barnsley on the train, one of her worst fears was that
her grandchildren would grow up to have accents like those she heard
around her. The broad Barnsley accent can be quite difficult to follow, and unintelligible to many from the South.
Some of our children’s contemporaries did indeed speak like that, but not them. As I mentioned in the last two posts, our daughter was teased at school for sounding ‘posh’, and was embarrassed by her voice in the two stop-motion video stories we made when she was little. It was quite a surprise when she said recently it is now her Yorkshire accent that bothers her.
The rather impressive subtitling on YouTube has no problem with it. It
transcribes almost all of it correctly. In fact, I wasn’t quite sure of
the word “daydreaming” until I switched them on.
I doubt it would have so little trouble with unmodified Barnsley. I also wonder what it would have made of my mother-in-law’s mixture of South London and “Snolbans”. I endlessly mimicked her pronunciation of “strawbrizz, raarzbrizz and guzzbrizz”? “They are raarzbrizz, not rasp
berries,” she would strike back.
And what of my own unbroken childhood accent? It can be heard in an exchange
45 seconds into the compilation I made from the old take of my dad singing and reading
poetry (Days of Wine and Roses, May 1st). It includes the following exchange:
(laughter)
Dad: Right. I am now about to begin.
Me: You’ll’ave all the laughing in.
Brother: Yes, you will, won’t you.
(more laughter)
Me: Hey! When you think about it what we’re all laughin’ at? It's a waste of tape.
Dad: My tape.
Embarrassing as I now find it (and there is a good deal more on the full tape), the YouTube subtitling copes with it surprisingly well. And although it struggles in places, it even follows most of my then sixty-five year-old Grandma’s village accent, fashioned before the First World War, as heard playing with my baby cousin later in the extract.
I also had a cassette tape of chatting with
friends as teenagers. Listening again recently, I was appalled, not only by the accents, but also by the language
used and what was being said. I rapidly abandoned my first idea of
sending it to them and threw it away. Now, I wonder what the subtitling would of made of it. I can’t imagine. We don’t always like what we see
or hear when we look back.
There is one further aspect of YouTube subtitling I find astonishing. It can automatically
translate into any one of over a hundred and twenty other languages. For
example, if you want it in French:
Not always perfect, but it can only get better. It can even do Welsh, Irish, and Scottish Gaelic. Who knows, one day it might be able to do Manx and the Yorkshire dialect?
One of the perks of working in a university is that you get to play with the latest bits of kit.
I was asked to get involved in one of the new multimedia courses springing up around the U.K. in the mid nineteen-nineties. Surprisingly, many were in engineering departments. I believe the first was started by engineers at Bradford University around 1993.
One element of our new course was digital video. We were all encouraged to understand how it worked. As a result I was allowed to borrow one of our new hand-held video cameras and take it home. It was great fun filming our children when little, playing in an inflatable dinghy in the natural pool on the beach at Sandsend.
I know that sounds like a frivolous waste of taxpayers’ money, but we needed to know how to use these new technologies ourselves, and understand how they might relate to other parts of the course and what their possibilities might be. Silicon Valley technology companies often allow staff time to ‘play’ with new software and equipment because it generates innovative ideas. In our case, it led to course developments and research funding.
Handling a video on a computer was not straightforward then. You had to run it through programs to digitise and ‘render’ it into a viewable form. You needed to be aware of the type of video coding (‘codec’) you were using. Only then could you begin to edit it or write programs to do state-of-the-art clever things such as spotting objects and faces. There would be a lot of ‘re-rendering’. Computers were so slow that every stage took ages. Nothing was automatic and effortless like now.
Back home, I realised that the camera made it easy to create stop-motion animation. With my then eight year-old daughter’s lovely wooden dolls’ house, the figures that went with it, and her enthusiasm and child’s take on family life around her, this, below, was one of our first attempts. Yet another example of something that would be much easier with today’s software. You wouldn’t even need a real dolls house. I know which I think the most fun.
She made up most of the story and moved the figures, while I mainly operated the camera. Surely, the story is not based on her own family, is it?
Moving from the public to the private sector was something of an eye-opener. It was a very different culture. I had not expected to be working with such an unprincipled set of spivs.
Previously, I had only worked in the accountancy profession and universities where the main considerations were thoroughness and accuracy. In accountancy, we checked everything to the penny. There was no short-cut sampling and rounding as now. It was similar in universities. We aimed to review and understand all previous work in a field before attempting to extend it. Where I did have dealings with the private sector, it was either with audit clients wanting to demonstrate compliance, or with the research arms of large companies governed by quality procedures. You could say that things were done properly.
Then, along came nineteen-eighties ‘Thatcher’s Britain’, when competition and cost-cutting were king. You could say that standards began to drop.
Universities were driven to seek commercial partners. By then, I could bullshit pretty convincingly about ways to make computers easier to use, so when a systems company with problems came along, I was sent to talk to them. It was not supposed to be part of the plan for them to offer me a job on a lot more money. Feeling near to burnout with university work, I took it.
It was a medium-sized systems company driven by sales and profit, with an eye on what things cost and how long they took. The computer system they sold had been developed for an equipment maintenance business, but as the system expanded to handle more and more business functions, other companies wanted to use it too, and it became valuable in its own right. By the time I joined, there were around seventy computing staff, and the system was used by some of the biggest firms in Europe, from cash machine operators to telecoms companies. It had become immensely complicated and few fully understood it any more.
I identified problems, improved the information provided to customers, and began to take on consultancy roles, as they said I would. I can’t complain about that. But I disliked the prevailing ethos which was aggressive, competitive and sales-led rather than professional.
It oozed down from the owner. He had left school early and chanced upon the opportunity to lease and maintain office equipment, such as internal telephones and fax machines. He was a first-rate wheeler dealer and could spin a good yarn, and the business grew rapidly. He was also arrogant and ruthless. I cannot repeat all the sexist, racist, homophobic and explicit things I heard him say. In one meeting, he complimented a non-white staff member on his wonderful sun tan, and asked where he went on holiday to get it. In another, he likened a map of Scandinavia, “where our biggest customers are, Ladies”, to a “penis and testicles”. I suppose he thought it humorous; the sort of humour I had not heard in years. His attitude was that if customers were not complaining, we were giving them too much too cheaply.
This brand of arrogance pervaded company culture. Many of the staff, especially in sales, went along with it. They were paid ‘loadsamoney’ to drive around in company sports cars. There was pressure to go out drinking and socializing with customers. I did not feel ‘part of the team’. I don’t know if others felt uncomfortable too, but if so, they hid it well. The promise of more money and a company car tends to keep people in line, even when they never materialise.
The owner did not tolerate dissent. If you wanted to keep your job, you kept quiet. Those who crossed him were sacked, sued or both. One employee broke his leg playing football and was dismissed because “the injury was his own fault”. Another left to set up his own company and foolishly solicited business from his ex-employer’s customers. He was brought to the brink of bankruptcy.
The firm took on large numbers of new computing staff to redevelop and modernise the system. When they had served their purpose, 50% of the systems division were made redundant. I was tipped off by my manager that it was coming. He said that even if I survived I should get out as soon as I could. The phrase “unprinciples set of spivs” was his. I survive but he didn’t.
In all, I stuck it out for nearly four years. As I said, it was well-paid. The crunch came one Friday morning when I had to drop everything to go to Stockholm to sort out an urgent problem. I popped home to pack a bag and leave a note that I might not be back until Tuesday. It began to look as if more work like this would come my way. It might sound exciting, but it was all work. There was no free time to see the places you visited.
Newly married, with a family in mind, this was not the kind of life we wanted. It was a relief a few months later to find another university job. Although on a lower salary, I reasoned that the public service pension benefits compensated for that.
Most university lecturers work very hard (at least in my experience). They spend hours planning teaching and helping students, and give up too many of their evenings and weekends dealing with email. I also used to put in further time carrying out research, writing academic papers and applying for external funding. With some success, I might add.
Yet I always had a sneaking regard for those who did basically what was asked of them and little more. One such colleague was called Mick Copier.
I first came across him when I still worked in the software industry. My employer sent me on a course in SSADM (Structured Systems Analysis and Design Method) and Mick was on the same course. Around a year later I got a job at the same university where he worked and found myself sharing an office with him. If truth be told, the course helped me get the job and Mick put in a good word for me.
Part of my role involved visiting students out on their work placement years. Late one morning, arriving back on the train, I was surprised to see Mick at the railway station. “Are you on a placement visit too?” I asked him. “No,” he said, “I’ve done all I need to do today so I thought I would have an afternoon out in York.”
Mick based much of his teaching around the SSADM course we have both been on. I sometimes used it too, but Mick took it to extremes. Every June, our office would fill up with boxes from the reprographics room. Soon they were stacked four or five high and three or four deep. They were his teaching materials for the next academic year. From October to April, all he then had to do was to hand out these pre-prepared notes and worksheets week-by-week and guide the students through them. They nicknamed him Mick Photocopier.
To be fair, he was extremely knowledgeable, and the students liked and respected him.
With his preparation all finished, Mick then took all his holiday in one block over the summer. While workaholics like me spent our time writing and researching obsessively, he kept a boat on the River Ouse and could comfortably make it to the Mediterranean and back on the French canals. One day I would be like that, I told myself.
Mick came unstuck in the end. Well, sort of. The university decided it needed to reduce the number of lecturers and began a redundancy consultation. I survived, largely because of my research output. Mick didn’t. Instead, he accepted a large voluntary severance payment and walked straight into a new and highly paid position with a nearby passenger transport authority, restructuring their database of bus and train timetables. He even took some of our students on placement. He knew what he was doing, in more ways than one.
I never did get to be like Mick. I think now that I drove myself far too hard.
In August, 1957, my grandfather bought me and my brother one of the first £1 Premium Bonds each. They had been introduced just under a year earlier on the 1st November, 1956, to encourage people to save. He bought us each another £1 bond in 1959.
Rather than paying interest, bonds were entered in a monthly prize draw, drawn by ERNIE (Electronic Random Number Indicator Equipment), a Colossus computer. They retained their original value and could be cashed in at any time.
In those days, the maximum you could invest was £500 and the top prize was £1,000, as compared to £50,000 and £1 million today. Also, today, you cannot invest less than £25 at a time.
I didn’t cash mine in. In fact, I later bought more, and once won £500. I still have the original two, along with the others, and my Premium Bond record shows a total investment ending in 02. The original bonds are now numbered 000AB01---- and 000AB76----.
The records are all electronic now, but here are my two original paper certificates.
A dutiful grandfather thinking of his grandchildren’s financial future? These two particular bonds have never won a thing.
I was encouraged by the interesting comments on my last post about the businesses I came across while working in accountancy in the nineteen-seventies, and the further thoughts they sparked off. The following captured my ambiguous feelings about it at the time:
Brown paper parcels containing vouchers, Cash books and day books, bank statements in pouches, Ledgers and ledgers, both sales and bought, Ticking up postings requires little thought.
One big difference between then and now was the lack of computerisation. Nearly all records were handwritten. Some were in beautiful leather-bound ledgers, and there was a sense of pride and skill in being able to keep them neat and tidy in fountain pen, without mistakes and corrections.
Others might be in scruffy self-duplicating docket books. It was interesting to follow them around factories, matching them to drums of dye colour, or to trace them from lengths of cloth to the despatch of finished items of clothing. This was done to ensure the accounting systems were working correctly and detect possible fraud (which was rarely found).
But often the books of smaller clients would be brought into our own offices where you might be stuck for several weeks bored to tears, hence my parody of ‘Favourite Things’.
I made distractions for myself. When we took on a model agency as a new client I was asked to produce a set of example book keeping entries for the owner to follow so that she knew how to fill them in. To the annoyance of my boss I used the names of famous models such as Twiggy and Jean Shrimpton, causing him to exclaim: “For goodness’ sake, Tasker, we’re a firm of Chartered Accountants, not Monty Python’s Flying Circus!” Too late. They were already inked into the first page of the cash book.
We also prepared sets of annual accounts for clients, filed them with the Inspector of Taxes on their behalf and dealt with their tax affairs. As a result I have never been afraid of dealing with outfits like HMRC or the DSS.
You could also get stuck of larger clients checking off lists against each other. It wasn’t called “double entry” book-keeping for nothing. At one cloth warehouse it took several weeks to work through the sales ledgers. Statistical sampling and tests of significance would not have been considered adequate then. We checked nearly everything.
Another big difference was the sheer variety of types of business. We made so many more of our own things before globalisation. Now, Central Leeds seems to be predominantly financial rather than physical, and nearly everything takes place at desks in offices.
Computers sucked the life blood out of everything.
If you want to copy of an old photographic colour slide or negative, say, to post online or to make a copy of someone else’s slide, what do you do? You take a photo scanner if you have one (I have a Canon flatbed scanner with a film and slide copier in the lid), scan in the image (I use 3200 or 4800 dots per inch), and, of you are a perfectionist, tidy up to dust marks and scratches with Photoshop or similar. It makes for a better quality image than you ever used to get projecting the slide on to a glass bead screen.
But what did you do in the pre-computer nineteen-sixties and seventies? Think: Tandy TRS-80 introduced 1977, Sinclair ZX80 and ZX81 in 1980 and 1980, the 8-colour BBC Microcomputer in late with 1981 and the Sinclair SX Spectrum in 1982. None of these would have been capable of running photo-scanning devices even if they had been available. For example, to Hewlett-Packard Scanjet was introduced in 1987. It operated in black and white at 300 dots per inch, could handle only reflected documents and not film or slides, and cost a fortune.
So what did you do? Another trip to the loft has found my slide copier.
I have the cheapo SLR Mk II version, basically which is a metal frame that just screws to the front of a camera lens. It appears to have cost me £5.34 in around 1974. Here it attached to the front my Zenith E single-lens reflex camera. I have also used extension tubes between the camera body and the lens.
It was terrible. I could never get it to produce a decent image no matter what kind of lighting I used.
For example, here, in a copy from a friend’s slide, I am nearing the top of Ben Nevis in April, 1974, straight up from the Glen Nevis car park. It has not been Photoshopped. I did not even manage to get the light consistent on this one. You didn’t get to see it until the film was processed, and the cost meant you couldn’t have as many goes keep trying until it was right.
Looks like another item for metal recycling. Thank goodness for modern photo scanners.
For the sake of completeness, here are the instructions that were in the box (or download as pdf)
You do odd jobs, you accumulate all sorts of bits and pieces, and you them keep because they might come in useful one day. You buy things and they wear out but you keep the bits and pieces that go with them because they might also come in useful one day. And, fifty years later, you have boxes full of all those bits and pieces, some of which may have come in useful but most of which didn’t.
Here is part of my lifetime’s collection of wires and plugs. Funny what memories they bring back!
I found the plug, socket and cable used to make an extension lead for
the fluorescent light I fitted under the eaves of my loft room in the
shared house in 1972, a short length of ring-main cabling from when I
installed several spur wall-sockets after moving into our current house
thirty years ago, and some left-over heat resistant cabling used to wire
up an electric immersion heater around the same time. Then there were
the transformers from old computers, printers and scanners, and their
plugs, sockets and adapters. I can still identify them: RS-232,
Centronics, VGA, S-Video, Ethernet, HDMI, DIN. There was even an old
cordless telephone system.
And where on earth were the following electronic components from? It might have been one of the kid’s Design Technology projects at school, involving transistors, capacitors, thermistors, a photo-resistor and light-emitting diodes. They remind me of my brother’s nineteen-sixties electronic engineer’s kit, or my nineteen-seventies home-built Heathkit stereo.
How many of the following does one really need?
spare 3, 5 and 13 amp fuses
spare mains plugs and multi-socket adapters
travel adapters for various kinds of power supply
transformers for long-gone printers, scanners and computers
cables for printers, monitors and keyboards
USB cables
ADSL micro-filters for connecting broadband to telephone lines
SCART leads for video recorders
mono/stereo audio/video jack plugs, DIN plugs, HDMI leads, S-video leads
television aerial cables
lawn mower cables
electric kettle cables
time-switches
wall sockets, light fittings and light switches
wiring of various lengths and thicknesses
If I don’t sort them now, someone else will have to do it. This is some of what will be going to the electrical skip at the recycling centre.
And the rest? Sorted into smaller boxes, labelled and back in the loft in case they come in useful one day.
A colleague told me in confidence he was desperate to leave the software company we were with. He was tired of having to spend so much time abroad. The week after he’d been to Venezuela they had sent him to Athens – talk about jetlag! Fortunately for me, he was away so much he couldn’t get to interviews. Had he escaped, I would have picked up all his travel. It was bad enough being sent away just occasionally, like being asked (i.e. told) on a Friday morning to go to Stockholm to sort out an urgent problem, and having to pop home to pack a bag and leave a note that I might not be back until Tuesday. Newly married with a family in mind, it was not what I wanted. I understood my colleague’s predicament entirely. I decided to get out before he did.
I started applying for lecturing jobs in Polytechnics. It would be a cut in salary, but not all that much taking pensions into account. I had to make my own provision at the software company, whereas lecturers were members of a government-backed, inflation-proof, final-salary scheme worth at least 20% on top of what they paid you. A salary of £20k was the equivalent of £24k, and £25k was worth £30k.
Things did not go well. I applied for no end of posts, but despite being well qualified – higher degree, authorship of academic papers from previous work as a research assistant, relevant commercial experience – it counted for little. I was interviewed often enough, but, no matter how well I felt I’d done, they appointed someone else. It was usually either an internal candidate or the cheap option. At Leicester Del Monte they appointed a twenty-three year-old straight off their M.Sc. conversion course. At James Heriot they appointed a mystery candidate who wasn’t there when the rest of us were interviewed.
Nearly a year went by and I was spending more and more time away. With one last throw of the dice, I applied above my league to the University of Nottingham. There turned out to be two posts and four candidates. We sat around after the interviews awaiting the outcome. It took ages. Finally, they called in the first successful candidate and then the second, but told me not to go away. I will forever be grateful to Professor Peter Ford who explained that they had appointed the two candidates with the broadest balance of skills, and had they been appointing to only one post it might well have been me. “Do not be discouraged in any way”, were his exact words.
I vaguely knew one of the successful candidates as one of those people who spend their lives messing others around and being unreliable, and it annoyed me a few months later to learn that he had chucked the job and moved on.
Polytechnics then changed. The government decided they were all to become universities, and they started to hunt for staff able to carry out research and bring in external funding. It was like a football transfer market. I applied to a Yorkshire institution and got an interview. In phoning to accept I discovered there were six candidates. Not good odds.
On the day only four turned up. Then, like at Nottingham, they said they were hoping to fill two posts. Two out of four looked promising until I learned that one of the candidates was an internal candidate called Anthea who was just about to submit her PhD thesis, another was a high-flying researcher from British Telecom, and the third an affable Rory Bremner lookalike who was a temporary lecturer at a Russell Group university.
We spent the morning giving presentations. I managed to work in stuff about something called SSADM (Structured Systems Analysis and Design Method), the expert systems research I’d previously done, and how it related to the commercial system I now worked with. The Head of Department though it an excellent presentation.
We were taken for lunch at which Rory Bremner did most of the talking and Anthea said nothing at all. Then the chap from BT was taken aside and didn’t come back. I heard later that his talk had been terrible, and they doubted his ability to connect with the Higher National students. The remaining three of us waited for our formal interviews in the afternoon.
It went badly. There were questions that caught me out and set me talking too loud and too fast, and they said not to wait around because decisions had to be approved by the Vice-Chancellor.
I waited ten days. The Head of Department was out so I phoned the personnel office. There was a muted conversation at the other end of the line during which I overheard the words “Bremner and Dunham” and “shussssh”. They said the decision was still awaiting approval. Soon afterwards, the Head of Department then rang me. Yes, I had a job.
The other post did indeed go to Rory Bremner. I felt sorry for Anthea who had to vacate her desk to accommodate him.
We were both still there twenty years later. One thing I learned during that time is that with these kinds of jobs, probably with any job, you can never truly be aware of all the considerations, and why you might or might not be successful.
I recently mentioned four boxes of discoloured colour slides I came across when scanning in. Several people suggested, and indeed showed, it was not difficult to recover at least something like their original appearance. I said I’d try, but needed to get out an old computer with Photoshop Elements which came bundled free with a scanner. These days they expect you to buy it over and over again with a subscription. I refuse to be treated as an income stream.
I got out the old computer but have not made much progress yet. This is not down to any difficulty with Photoshop, but because of distraction. The old computer also contains a set of PC-Rail signalling simulations.
They might not sound it, but they’re great, they really are – not because of what you do or see but because of what you imagine. You pretend you are controlling all the trains through York, the noise and the power and the enormity of the things, and imagine being on board, remembering journeys once made.
It could be the summer of 1983, when they invited me to interview for a
research job in the world-famous Department of Artificial Intelligence
at the University of Edinburgh. I travelled up from Hull and back in a
day, changing at Selby during its last months as a station on the East
Coast Main Line before being bypassed by the coalfield diversion They
wanted to offer me the job too – they phoned the same evening – but were
then overruled by the funding council who insisted on someone either
with or close to finishing a Ph.D.
Or it could be any one of the
many other times I’ve been through York by train, up to Newcastle,
Edinburgh or Glasgow, visiting
clients when I was with the software company, or later, to see students
on work placement. I once went to Aberdeen on the overnight sleeper, did what I had to do there, returned the next night and was back at work by 9 a.m.
It’s tricky signalling a path through York for the Scarborough Transpennines. They come in from Leeds on the top left of the above screen and need to get to Platform 4 and the Scarborough line on the bottom right. The screen shot shows train 1B23 (Blackpool to Scarborough) nearly there after crossing the East Coast Main Line just outside the station. I have to be careful not to hold up trains from Doncaster and London. I am being distracted by train 2C26 coming in from Harrogate at the other end of the station (below) where it has to get to Platform 8 without holding up trains from Newcastle and Edinburgh. Fortunately, it’s not very busy – not yet.
Sheffield is great, too – quite demanding. You control everything from Dore Junction and the Bradway tunnel south of the station (on the left in the screenshot below), to Meadowhall to the north. You have to put goods trains into loop lines to give priority to the London and Cross Country expresses on the Midland Main Line. Oh to be on the Aberdeen to Penzance!
I’ve been through Sheffield a lot too: south to the East Midlands where the software company was based, north to Leeds, York and beyond, and East towards Doncaster and Hull when I lived and worked there. These days you might find me taking the Barnsley branch home. Mother-in-law used to do it when she travelled up from Hertfordshire and changed trains at Sheffield, complaining it was so much easier when we lived near Nottingham, horrified by the Barnsley accents on the local train and dreading her grandchildren might grow up to speak like that. They got called posh at school.
The full simulations are not free, but there are evaluation versions which run for thirty minutes or so without charge, which is all I have ever done. With well over a hundred different stations or eras, there is plenty to do. Some are “heritage” simulations which recreate mechanical lever-framed signal boxes communicating with adjacent boxes through working block instruments and bells. I’ve played with quite a lot of them, both modern and heritage, always there personally in the mind’s eye.
As I am sure you know, the factorial of any positive whole number is that number multiplied by all the numbers between it and 1.
So the factorial of 3 = 1 x 2 x 3 = 6 And the factorial of 5 = 1 x 2 x 3 x 4 x 5 = 120
I am also sure that, as a computer programmer, you could quickly write a program to calculate the factorial of any number N. One way to do it would be to set up a counter to cycle through all the numbers between 1 and N, multiplying each by a running total that is initially set to 1. In an imaginary programming language it might look like this:
RunningTotal = 1 FOR Counter = 1 to N Multiply RunningTotal by Counter; (thereby altering the value of RunningTotal) The factorial of N = RunningTotal
So, in calculating the factorial of 5, each step of the cycle would produce the following values:
Counter
Multiplication of RunningTotal x Counter
New Value of RunningTotal
1
1 x 1
1
2
1 x 2
2
3
2 x 3
6
4
6 x 4
24
5
24 x 5
120
But there is a more elegant way. This involves thinking of the factorial of any number N as being that number multiplied by the factorial of N-1.
So the factorial of 3 = 3 x 2 = 6 And the factorial of 5 = 5 x 24 = 120 And the factorial of 6 = 6 x 120 = 720
In our imaginary programming language, the program to calculate factorials using this method might look like this:
The factorial of 1 = 1 The factorial of N = N x the factorial of (N-1)
This is known as a recursive function because it has to re-use itself at each step of the calculation. For example:
The factorial of 5 = 5 x (the factorial of 4) The factorial of 4 = 4 x (the factorial of 3) The factorial of 3 = 3 x (the factorial of 2) The factorial of 2 = 2 x (the factorial of 1) The factorial of 1 = 1 (this causes the calculation to “unwind”) So, the factorial of 2 = 2 x 1 = 2 So, the factorial of 3 = 3 x 2 = 6 So, the factorial of = 4 x 6 = 24 So, the factorial of 5 = 5 x 24 = 120
Isn’t that just exquisite!
Now, for homework, please would you explain the operation of recursive descent parsing giving examples from the Hebrew and Cherokee languages.
Sorry, it is not what you might imagine, it’s a computer game. You fire coloured balls from a gun. When you place three or more of the same together, they explode and disappear.
Bouncing Balls Level 6
In the screenshot shot the yellow ball from the gun will bounce off the right hand wall to hit and destroy the group of yellow balls at the top. Actually, a better move would be to take out the four yellow balls near the top on the left. This would leave a large group hanging without support, so they would fall and be destroyed too.
As you play, the balls move slowly downwards. To win, you have to destroy them all before they reach the bottom. You then progress to the next level which has more colours and less time.
Here is another screenshot: the leaderboard on the Novel Games site. I’m fourth. Fourth in the world! Impressed? If it were lawn tennis, I could be Emma Raducanu.
Thankfully, I’ve never been bothered by the all-consuming games that get talked about: Grand Theft Auto and Fortnite, etc. It’s the mindless ones that get me. Hours have gone on Pacman, Freecell and Minesweeper.
I first fell in 1983 while writing educational software in a university. I went in one Sunday to sort out a problem, which, like a lot of programming problems, turned out to have sorted itself out in my head without thinking, so it only took ten minutes. As there was no one else around, I switched on the Apple IIe and began playing Arcadians, a space invaders game. The ‘just-one-more-go’ syndrome had me still there at ten at night. I’d got pretty good by then.
Bouncing Balls is an unusual game for someone with my colour vision to play. At first, the red balls looked nearly the same as the green, but I gradually learned to distinguish them well enough to get to Level 9 when an orange ball is introduced. This, to me, truly is indistinguishable from the green one.
At Level 8 I cannot distinguish a difference between the green and orange balls
indicated on the left. The protanopia filter makes the green darker and alters some of the other colours too.
The way round it was to use the Windows 10 colour filter for red-green protanopia
(Settings – Ease of access – Color filters), which makes the green look darker and allows me to get to Level 12 before
it becomes too fast.
But, my score on the leaderboard is way beyond this at Level 22. How?
I got a new computer. It is more powerful than the old one and runs Bouncing Balls so fast I can’t get past Level 8. Can it really be that the power of the computer affects the speed of the game? Yes, it seems. On an even older tablet the game runs even more slowly. Most unfair.
I remembered there is a Windows 10 system option that restricts the power of the processor*. The new computer does not have it but it is there on the old one. Does Bouncing Balls run more slowly under reduced processor power on the old computer? Yes it does.
There you have it. As you go up through the game level by level, you reduce the power to 50%, then 40%, then 30%, and so on, down to 0%. That’s how you get a score of 414,270 at Level 22.
Just a word of warning. Remember to reset it back to 100% before you turn the computer off, otherwise you might have to wait an hour for it to start up again.
I doubt I’ll be fourth for long when other players read this, assuming Novel Games don’t remove me first.
As for Emma Raducanu, my wife’s nephew grew up in Bromley where, at the tennis club, he was asked to play against a young girl three years his junior. You can guess the outcome. I only hope she doesn’t become addicted to Bouncing Balls. She would be top of the leaderboard in next to no time – without cheating.
*See: Settings – System – Power & Sleep – Additional power settings – Change plan settings – Change advanced power settings – Processor power management – reduce % as needed. Leave the window open so you can get back easily to change it, and don't forget to put it back to 100%. It looks like this:
