Bases other than 10

Originally published on my OU study blog while studying module TU100 'My digital life'

Working through Block 1 Part 2 Session 6 triggered a memory from school from when I was 10 or so, when my parents wrote a letter to the teacher to say that “Emma has not quite grasped the concept of base six numerals”. Indeed I hadn't, and I'm not sure I ever did - I think possibly we just moved on to a different topic.

It did make me wonder what bases other than base 10 are used for. Block 1 explains that binary numbers are used in computing, so OK, I get that. Session 6 notes that base 16 (hexadecimal) is useful in some branches of computing. But what about other bases, such as base eight or indeed my old nemesis, base six?

I briefly Googled the base six numeral system. According to Wikipedia https://en.wikipedia.org/wiki/Senary it’s also known as ‘senary’. Interesting section on languages believed to use senary numerals.

I worked through the various conversion activities in Session 6 but I can’t say this stuff is intuitive. Especially converting from decimal to binary – what a faff. Nightmare keeping track of the columns and the 1s and 0s. The Sense activity (Activity 39) was quite fun though.

Charmed to learn that a set of four bits – half a byte – is called a ‘nibble’. Apparently the term is rarely used …

A conversation with ELIZA

Originally published on my OU study blog while studying module TU100 'My digital life'

In Block 1 Part 2 we learned about ELIZA, a computer program whose DOCTOR script simulated a Rogerian psychotherapist. Apparently ELIZA was one of the first chatterbots, though I’m not too sure what this means.

As suggested in the course materials, I tried having a conversation with the OU's version of ELIZA. My input is introduced by asterisks (*). I found her abilities somewhat limited.

The first computer I remember using

Originally published on my OU study blog while studying module TU100 'My digital life'

Relates to Activity 1 in Block 1 Part 2.

The first computer I remember using was an Amstrad computer that my father bought when he set up his own business in the late 1980s. It ran a word processing program called LocoScript, and had a daisy-wheel printer attached.

The clip of the screen shown on the Wikipedia entry on LocoScript here takes me back. To do things, e.g. create and edit files, you entered keyboard commands – e.g. ‘C’ for create a new document. There was no pointing and clicking with a mouse – you went up and down with the cursor. Also, the screen didn’t display what you typed in the way it would actually look, as they do now – you got the same green type on a black background whatever you did.

I was around 18 by the time I used my dad’s Amstrad. We never had a computer at home before that, though I know some people did have home computers earlier in the 1980s. At school, there was a computer room, but it wasn’t very accessible to most pupils. There was a computer club that another girl and I once went along to, but we felt sneered at by the computing enthusiasts there (all boys) and never went back. Thank God computers are much more accessible to everyone these days.

When I started work shortly after that as a secretary, I used a variety of word processing packages. Temping in the late 1980s/early 1990s meant having to learn a whole variety of packages depending on the job you went to – I used WordStar, WordPerfect and DisplayWrite 4, and probably others that I’ve forgotten. Whatever you think about Microsoft, the advent of Word must have made temping a whole lot easier!

A search for Emma Thomas

Originally published on my OU study blog while studying module TU100 'My digital life'

Tried out the 'Google yourself' Activity 13 in Part 1 section 4.5.

What was revealed about me?

Expectations before doing this: I’m expecting to have some difficulty finding references to myself, as I imagine there may be a lot of other Emma Thomases out there.

How far down did I have to go before finding a reference to myself?

I scrolled down the first 20 pages of Google hits and couldn’t find a single reference to myself. I gave up after that. I suppose I can at least conclude that I’m reasonably anonymous.

Adding the keyword ‘Essex’ (I did my postgrad degrees at the University of Essex) did bring up my LinkedIn profile page on the first page of hits. Adding the keyword ‘Open’ (I work at The Open University) again brought up my LinkedIn profile page, as the first hit.

What was revealed about other people with the same name as me?

Mainly, that there are a lot of them.

Of the top 10 hits on ‘Emma Thomas’:

Other Emma Thomases seemingly more famous than me

I used to wish I had a less common name (and still do sometimes), but I suppose my name has some advantages.

The telephone

Originally published on my OU study blog while studying module TU100 'My digital life'

Relates to Part 1: 1.1 The telephone.

I found this comparison of the development of the computer to the earlier development of the telephone, really interesting. I've often thought about this when encountering people who seem really opposed to social media such as Facebook. How must the telephone have seemed when it first started to become widespread? Did some people pronounce that it would have terrible consequences for human relationships? Was it dismissed as a new-fangled piece of nonsense that would never last?

Also I thought about how the switch to STD must presumably have put a lot of operators out of work. This Lady article refers to the work of telephonists in the days when calls were manually connected. This book apparently describes working as a GPO telephonist. This Sunday Express article is interesting and notes that 'The job of operator became a popular choice of career for women in the early and mid-20th century.' It concludes: 'In an age when it is so easy to contact anyone, anywhere, something of the magic of the early years of telephony has been lost.' Over-nostalgic? I don't know as I don't remember the time when you had to go through an operator to make calls. Do older people feel nostalgic for the age of the operator? I can see how a human element in the process of making a telephone call has been lost - though the flip side of that is that it's presumably a lot quicker and easier now to reach the person you're actually trying to speak to.

(Why were long-distance calls called 'trunk' calls?)

What was the job of a ‘telephonist’? This job is referred to in The Best of Girl, published in 2006, a collection of extracts from the 1950s Girl comic, as part of 'Girl's Special Series on Careers'. It begins: 'Vivien has a pleasant voice and a good memory and hopes to become a telephonist when she leaves school', and goes on to outline the training that Vivien undergoes and the duties of the job. It also shows a male friend greeting Vivien with "I hear you're one of the 'Hello Girls' now". To which Vivien responds yes, she is, and she's "awfully thrilled".

Fire and brimstone; more August activities

Received this inspirational pamphlet through the door recently. As evidence for life after death, it features a number of quotes from dying people who had behaved shortly before death in a manner interpreted as meaning they saw glimpses of “the other side”, including one Augustus Toplady, a hymn writer, who cried out “Oh, what delights!”, shortly before, presumably, dying, and a May Wilcox, who allegedly threw up her arms exclaiming “Oh, do you hear the music!”. Presumably the delirium of fever had been ruled out as a possible cause. Less fortunate souls included a Mr W, who allegedly cried “I am in the flames! Pull me out!”, an Unnamed Infidel, who saw a great high wall rising around him, and one Sir Thomas Scott, who, somewhat puzzlingly, cried “Begone you and your trumphery.” It ends (right) by suggesting ways in which one can avoid ending up in the lake of fiery torment, including sending for a free leaflet on how to prepare for Heaven courtesy of A & M McBride of 61 Sealstown Road. Thank God there are people like them who are willing to share their knowledge.

Overdue catch-up with Claire back in August at The Bull at Sonning, where we had a lovely Friday evening dinner sitting outside. Claire has recently left the hospital near Oxford she has been working at and has started a new job as an assistant Psychological Wellbeing Practitioner, part of the NHS’ IAPT service. She had been doing a week or so’s training over near Shinfield when we got together, but is apparently going to be based in Bracknell, which she didn’t seem too thrilled about. We had a look around for George Clooney, who has apparently been to The Bull since moving into the village, but no sign. Claire noted that she’s been going there more often than usual in the hope of seeing him, but no sightings as yet. Uri Geller has, conversely, recently left Sonning to move back to Israel, after living in the area for many years.

Cat
This cat, believed to be resident two doors down, has recently been spending more time in our garden, and a few weekends ago I had to chase it out of the dining room more than once. There are two small children and a dog resident at its own house, so we feel it may be searching out a quieter environment. Have some sympathy with it, but we are reluctant to condone its coming into the house as Harley is (perhaps naturally) nervous of cats.

Afternoon with the Clarks on 22 August. Arrived at their house to be greeted by Ray Sr, who gave me a brief update on how things were with the family, then Carol and I walked around the corner to Ray’s sister Caroline’s house, where we spent a few hours at Caroline’s younger daughter Leonie’s tenth birthday party, though in practice we were able to spend most of it sitting in the kitchen chatting while Leonie and her friends did crafty things in the front room. Had a couple of slices of Meat Feast pizza, plus a few dips in a chocolate fountain that had caused Caroline’s husband Tony a certain amount of stress in the preparation but which turned out OK in the end. Tony and Caroline told me about Cosmo, a restaurant on Friar Street that I’ve never been to but which apparently has an amazing chocolate fountain – indeed Tony had a photo of it on his phone. Perhaps it’ll have to be tried. I have reservations about ‘casual dining’ (presumably, aka help yourself buffet) but perhaps I should overcome these.

The following day I galvanised Ruth into going for a Sunday walk with the promise of early evening dinner in The Griffin afterwards. We took the 25 to Peppard Stores, the last stop on the line, and then walked up to Peppard (via the ‘ravine’ referred to in the Wikipedia piece) and turned down Church Lane to the church. Saw Henley House through the trees, according to this Geograph entry the former rectory; looks as though it was for sale a couple of years ago.  After wasting some time on a bit of footpath confusion, gave up and took a footpath leading from near the church south to Sonning Common via Spring Wood, where we passed Sedgehill Spring before coming out onto Blounts Court Road, where we went for a drink at the Butchers Arms. Ruth picked up a soggy bag of runner beans from among some for sale outside someone's garden.

Soggy runners
Barbecue
Went down to Mum and Dad’s for the August Bank Holiday weekend. Had a fairly quiet time with a wander around Abergavenny on the Saturday afternoon and a family lunch with Hannah and Henry on the Sunday. A barbecue was attempted and didn’t work badly, but then it unfortunately rained most of the time we were actually eating. Dad insisted on sitting outside claiming the air helped his breathing, so Ruth and I gamely sat out with him while the others huddled in the conservatory. Ruth took the train back to Reading on the Monday while I stayed over until the Tuesday morning, mainly to avoid the gridlock caused by the festival departure day. Mum and I went for a pleasant walk around the town house-snooping in the afternoon.

Found Harley in this entirely unacceptable position last weekend. Told him he is not a cat and should get his bum off my pillow. I blame Willow - he never jumped up on the furniture until he saw her do it.

Birthday; impending dentistry

Took the afternoon off on 12 August to go and watch the last part of The Hobbit trilogy with Ray. We were both left distinctly underwhelmed by the film; the story really doesn’t merit having been stretched out into three parts – or at least, if you’re going to, spend the extra time on the characters and fleshing out interesting strands of the story. Battles, and the build up to them, are officially Not Interesting. Well, not to me, anyway.

Ray shared the news that he has been successful in securing a mooring at Enslow Marina on the Oxford Canal, so will be leaving the Thames & Kennet sometime during September – date to be fixed partly depending on the weather. I vaguely know the stretch of canal as he and I went for a walk near there a few years ago. He didn’t seem fazed by the prospect of the longer distance he’ll have to drive to work, but I guess will see how it works out in practice.

Spent a few hours at Gail’s husband Rob’s 40th birthday party a couple of Saturdays ago, though he isn’t actually 40 until mid-September. It was one of those parties containing different categories of guests, none of whom knew each other, so there were the inevitable little factions. Ruth’s mum and aunt were both there, so we spoke to them for most of the time, though I did dimly recognize one guest as working for Reading Borough Council (as does Rob), as I think it was him we saw about our Building Notice for our once-planned upstairs bathroom. The occasion did feature a hog roast with some pretty excellent crackling.

Kyoto Garden
On the Sunday and Monday we had an overnight stay in London, as last year, to celebrate my birthday, again staying in a Premier Inn on the Sunday night, this time the London Holborn hotel. We started by getting the bus over to Kensington High Street and seeing if we could visit the Kensington Roof Gardens – sadly not, as they were closed until the following Wednesday, but they sound worth a visit. They are on the roof of the building that evidently used to be the department store Derry & Toms, according to Ruth’s aunt, who evidently remembers it - as it closed in 1973, I don’t. Also hadn't realised that Barkers had now closed, though thankfully the spectacular building is still standing. I used to go to Kensington High Street reasonably regularly in my late teens and early twenties - partly because of the now long-closed Kensington Market, where I bought a little black jacket with now-unfashionable shoulder pads, which I still have - but haven't been anything like so much in recent years.

We walked down the High Street and had a look at the Kyoto Garden in Holland Park, though it was rather crowded. Then – claiming birthday dibs – I made Ruth walk down to the King’s Road, which I thought a pleasant stroll through posh streets, including The Boltons, but she confessed partway round that she isn’t quite as enamoured of just walking around in London as I am. This is a serious blow - though as I am not quite as enamoured of browsing shoes, handbags and jewellery as she is, it probably evens out. We did stop for a cup of tea en route. Made the discovery that Heal’s on the King's Road has closed its doors and seems to be becoming a Metro Bank – how sad. The Tottenham Court Road branch appears to be still there at the moment. We had a browse in Peter Jones as Ruth is on a quest for a new handbag, and also in Peruvian Connection, where she bought a dress. Then caught a bus across town and checked in at our hotel on Red Lion Street.

We made our way down to Soho in the evening for a cocktail at Balans, the bar opposite Comptons that we’d been to previously. This time I had made my mind up to have a cocktail, and decided beforehand to go for a margarita, being the only cocktail I’ve so far tried that I’d order again. However, in a fatal moment of trying to vary things, I went for a frozen rather than a classic margarita and decided to have it flavoured with passion fruit, with the result that what arrived just looked like a helping of sorbet, albeit alcoholic. Perhaps I’m not cut out for cocktail bars. The three young chaps at the table next to us were sharing a bottle of rosé, so perhaps we should have gone for that. Afterwards we wandered round trying to identify somewhere to go for dinner, and made the somewhat odd decision to try Garlic & Shots, a low-key looking establishment that looks a bit out of place among the mainly quite smart restaurants in the area. However, it was a bit of a laugh: remarkably dim lighting, pleasantly cheap yet drinkable house red, pleasant serving staff and an informal atmosphere. We did indeed have some delicious roasted garlic, accompanied by garlic bread, to start. For a main I chose the baby back ribs, though ended up envying Ruth’s steak.

On the Monday morning I’d booked us in for breakfast at the Darwin Brasserie at the Sky Garden, which I’d only been dimly aware of before but my colleague Jill had been there with her family a couple of weeks before and recommended it as somewhere to go. Having been there, it’s certainly an amazing space with incredible views – we were lucky to go on a clear sunny morning – though I thought the term ‘garden’ somewhat overblown – it’s really more in the way of a bit of planting. A few pics here. We had a nice if expensive breakfast at a table with a great view. Only downside was the un-warmed croissants, which I duly left a comment about in a TripAdvisor review. Well, you have to, don’t you.

After leaving the Sky Garden we checked out and made our way over to Tate Britain – where I’d not been for a number of years – to see the Barbara Hepworth exhibition ‘Sculpture for a Modern World’. Some beautiful pieces on display. I’m keen to see the Sculpture Garden at her former studio, but that does necessitate organising a trip to Cornwall, which I haven’t done yet.

Episode of toothache a week or so ago in the molar that was diagnosed with a crack earlier in the year (bit down on something, possibly a salt crystal, in tooth with large filling; X-ray subsequently showed crack under filling; dentist made woeful noises about possible root canal needed in future). Partly in fear of likely cost of major dental treatment and partly due to thinking that I really should register with a dentist in Milton Keynes, I made attempts to register as an NHS patient with a dentist here – however, despite having spent a lunch hour going in and filling in their registration form, they still haven’t confirmed that they’ve registered me. As a result, when toothache became worse a couple of weeks ago I panicked and booked an appointment at my private dentist in Caversham. My usual dentist was away and I had to see her stand-in, a chap named Peter who suggested that my toothache might be due to bruxism (apparently the latest buzz thing in dentistry). He even gave me a Post-It with 'Bruxism' written on it, so that I could Google it. As I was visibly sceptical, he hedged his bets and gave me a 7-day course of Amoxicillin as well, thus possibly contributing to the apparently rampant problem of over-prescription of antibiotics – though in my case no one can say that I demanded them, as I don’t think I’ve taken antibiotics since childhood (if then). I dutifully finished the course, and my toothache did wear off about halfway through the course, though whether because of anything to do with the drugs, who knows. Saw my usual dentist Jill earlier this week, who confirmed that bruxism was NOT a likely explanation of my toothache and suggested various treatment options. Have said I’ll go away and think about it.
