Great stuff from 2014.
Here is an example from Michael Bennett,
While traveling recently in Tanzania, near Lake Manyara National Park, we came upon the most ordinary of sights. Yet it reminded me of the unstructured (unsupervised) sport and games played in youth.
We were returning at dusk to our hotel near the park, along a red-dusty rough ‘road’ – safari vehicles only.
The photo provides a glimpse of local lads (mostly boys) at play. Just off-camera to the right was a casual football game, down a decline from the road. Looking closely we see,
- a bicycle and rucksack on the ground
- a boy holding up his hand to us, possibly because his friends are crossing
- two, perhaps brothers, standing together in the centre
- on the right is someone watching, or joining, the game
Remember pedestrians always have the right of way at zebra crossings.
On this day in 1822, Charles Babbage proposed a ‘Difference Machine’ in a lecture to the Royal Astronomical Society of London, ‘Note on the Application of Machinery to the Computation of Astronomical and Mathematical Tables’*
His difference engine is a mechanical calculator that evaluates polynomial functions. The name comes from the method of divided differences, a way to interpolate functions by using a small set of polynomial coefficients. Most mathematical functions commonly used by engineers, scientists and navigators, can be approximated by polynomials. A difference engine can, therefore, compute many useful tables of numbers. Babbage is credited with the concept of a digital, programmable computer.
The errors which arise from the absence of facts are far more numerous and more durable than those which result from unsound reasoning respecting true data**.
*This is the title from the Memoirs, or as we would say today Proceeding, of the Royal Astronomical Society. Later Babbage published the abstract of his talk in a book and used the title, ‘A Note Respecting the Application of Machinery to the Calculation of Astronomical Tables’.

Here is a recent conference article, published as an e-book,
D. Williams and P. D. Burns, A Decade of Experience with Digital Imaging Performance Guidelines: The Good, the Bad, and the Missing, IS&T’s Archiving Conference, 2017
No, this is not about KPIs or archery. Upon landing at San Francisco we saw what appeared to be, surveillance camera calibration targets.
This video is the result – based on a true story.
When I was at the Electronic Imaging Conference in San Francisco in February there was a man with a parrot attending. He walked around with it and brought a cage to the conference rooms when he was attending. On the last day of the conference, I was near the back of a room where a speaker was being introduced. The parrot said ‘Hello!’ and it resonated. Everyone turned around for a second then the session continued.
Leaving the room later, I passed the parrot in his cage (he had been taken there by his owner). I talked to the parrot to see if I could record it, but no luck. I just got a squawk.
Later I imagined a BBC radio story, The Parrot at the Conference (audio).
Recently the UK Royal Mint issued a set of ten-pence coins, the A to Z 10p Collection. Below is part of a picture posted by Sharon Henley, head of Marketing at the Mint. Preparing for the Archiving conference (#Archiving2018) next month, this got me thinking about old and new coin circulation. Those we keep and those that return, sometimes unnoticed, after our travels.
First, I am not a collector but I do find stamps and coins interesting. Coin designs are usually meant to celebrate, document, or at least note, the issuer’s history, culture and government in a serious way. The A to Z 10p Collection coins are quite different. They celebrate things British that are both unique and common-place. They are angelic, monstrous, sporting, double-deckered, full-English, ‘henged, oaked, parliamentary, artistic, and the rest.
Please note these are serious matters, and by all accounts the collection is highly successful.
Well, in our private coin ‘collection’ (stored for random-access in dresser drawers) we have quite a few coins from quite a few places. Checking the countries and dates, it is easy to discern an approximate record of family travels. Having extended-family members (whom I have visited) in five countries, and traveling rellies results in a fairly wide net. An approximate sampling of time and place.
Those from the UK show a few that were in circulation when we emigrated, just prior to conversion to decimal currency (1971). Some are much older, of course, and represent the random, or ‘interesting because they are old’ group. Two 1919 pennies are probably from Grandpa. However the 1945 half-penny was recently given by local friend, but could not resist including it. My more recent visits to England are also represented.
We also have Panamanian Bolivars and Australians pennies (and cents), alongside our neighbours’ Mexican pesos and Canadian loonies. Then there are the others,
- Argentina: attributable to a brother-in-law’s trip in the nineties
- French francs (pre-Euro) from a visit to Paris where I presented at an imaging conference early in my career. I still have the paper, which I had translated and typed (yes, typed on paper) in French.
- Peruvian nuevo sols (or is it nuevos sols) from a holiday with friends
- Japanese yen, from another conference in 2002
- Turkish Lira
- Bolivian Boliviano: not sure where this came from, but naming this as I did seems redundant: Boliviano means Bolivian! (noun-adjective duality)
We found lots of others of course, but then …. maybe I am a collector – of connections to family, colleagues and friends, via the things that end up at home. Bet you have few too.
p.s. The Union Flag (I think) is one that was sewn on a backpack that traveled through Europe with my younger brother as a university student. Wonder if he wants it back.
