Photography Workflow (Again) - Part 1

Upgrading to Yosemite SP2, or whatever they call it, brought Photos to my Air. That made me take another look at how I organise my photo collection. I had a crack at that last autumn, but lost the motivation to carry on.

What did the old-school photographers do? The famous guys who shot actual film? Turns out that what they really did was shoot reels and reels of it, and then tossed them undeveloped into a draw. Even when they developed the reel, it was likely dumped into a box and forgotten. Seems that for many of the big name pioneers, photography was compulsive, and that it’s taking the shots that matters, rather than cataloguing, displaying and archiving them. All those undeveloped reels are then a sad story of what happens when we dedicate our lives to something, and the market moves on, leaving us behind.

And then they were, after all, professionals, and if no-one was buying, then why waste money on the work? The costs of printing, and the time it took to make a good print, meant that the professionals mostly left the reels as negatives, maybe made contact sheets, and rarely made actual prints. The point was to take photographs and then sell them, not to make family albums and scrapbooks.

That’s not the point for ordinary folk. Ordinary Folk want to use their photographs to show off what a great life they have share their experiences with their friends. Millions of gallons of oil are burned annually to cool data centres dedicated to storing and delivering photographs of cats, weddings and three girls striking silly poses inside a nightclub. Ordinary Folk want to walk look through their albums, or scroll through their Photos, to walk down Memory Lane.

I’m not a professional and I’m not Ordinary Folk either. I’m not keen on Memory Lane, and my life is utterly boring. My photos aren’t about my life, but about what I see, so I guess that makes me an amateur photographer. That is, my attitude to photos is the same as a professional’s, but I don’t make money out of it. I’d like to find the better images I take, print them and hang them around my house. Maybe I’d put them on Flickr or Instagram. Some appear in this blog. I had hundreds of prints of film photographs I took back when I was using an OM-10 and one day went through them, kept the best and discarded the rest.

What I want to do is work on digital photographs. On my Mac Air. At the moment, the archive is on a 2TB Western Digital NAS, and Macs…. really suck at handling NAS. My Air won’t even automatically re-connect to one when coming out of standby or sleep mode, something Windows does automatically. Mac laptops are designed as stand-alone machines for use in cafes. Sure I can see the archive using cover flow in Finder and then inspect the picture in more detail, but that's not the experience I think I want. What I really want is Irfan View for Mac, but that’s not going to happen. Irfan View creates what amounts to a huge contact sheet, but without all the overhead of the usual photo-management packages.

The bigger photo-management packages use databases to handle thumbprints and editing actions, and to remember where the package put the original files and where it created any working copies. If users are allowed to move files around willy-nilly the management packages will lose track of them, pushing holes in all those albums and themes, and breaking links between a picture and the editing actions. Clearly the guys who designed Picasa and Photos don’t like the idea of having source files on a NAS device, and maybe for that reason. This can make these packages space-hogs.

At which point, I thought it might be a good idea to find out how large my archive is. And that, with its consequences, will be revealed in the second part of this post.

Cheryl's Birthday and Other Trick Maths Questions

So this went viral this week.

I hate these things. But I buckled down (at work!) and did it in 15 minutes. It helped to draw the dates as a matrix: months on the top, dates down the side.

The press spin is that 15 year-old kids in Singapore are smarter than almost everyone in the Western world. The excellence of Singaporean secondary education is a common trope of the western press, closely followed by the superiority of Chinese, Japanese and Korean secondary education.

Of course this is nonsense. For one thing, this superannuated grey-haired Anglo did it in about fifteen minutes. (I usually do the “Can you answer these GCSE questions” quizzes and I always ace them in a very short time though not after a couple of mis-steps along the way. The day I can’t ace them is the day I will apply for a job in product development.) For another, the exam board itself stated that this question was to help identify the better students.

And for another, this isn’t a serious question. It’s a trick. It’s the kind of trick question that a certain kind of epistemologist likes to use to discuss abstruse issues, and it’s the epistemological analogue of the trolley problem.

What makes a problem a mere trick instead of an interesting problem? An interesting problem gives rise to some theory to solve it: anything from an algorithm to a 400-page mathematical paper full of abstruse theorems. A trick is solved by a non-transferrable, non-generalisable argument. Remember all those integrals you had to solve at school? You had to play guess-the-substitution that would turn them into simple ones. Finding substitutions is a a trick. Integration by parts is a method, even if it does involve some trial-and-error.

Tricks give people the wrong idea about what a subject is about. The maths A-level syllabus used to be strong on tricks, whereas real mathematics is mostly about geometric insight to suggest theorems, and algebraic slog to prove them. Not finding a transformation or algebraic manipulation that magically makes the answer appear. Ask a serious chess-player whether they do chess puzzles: most of them don’t.

But the general public likes tricks. It likes to think that maths, or chess, or anything else that requires lots of reading, understanding, and actual insight, not to mention lots of trial and error, is really about seeing-something-that-makes-it-easy. Because that makes it magic, and the general public don’t mind not being able to do magic. Magic is, after all, just tricks. But if it’s hard work, and guessing and learning from mistakes, and adapting techniques you read about in some other contexts (that means reading, right?), then we’re looking at choices of how they spent as an adolescent, and now spend as an adult, their time and energy.

And guess what? Most people made choices that means they can’t solve a problem that bright 15-year olds in Singapore can solve.

Peeled Potatoes, The City

First thing in the morning, outside the pub. That's where all those rostis come from.

18 Rules About Scientific Theories and Other Claims By Scientists

Rule 1: Any scientific theory that resembles a Biblical myth, or any creation myth from any other culture or religion, can be rejected without further examination.

Rule 2: Anyone who claims that scientific theories have immediate consequences for social, moral or political policy has to remain silent until they have read Hume’s Treatise on Human Nature and understood why they are wrong.

Rule 3: Any explanation of current behaviour in terms of how human beings lived twenty thousand, or any other number of, years ago, can be replaced by a better explanation referring entirely to the current economic and material circumstances and personal goals of the people involved.

Rule 4: Any scientist who claims their theory shows that people do not have freedom of choice certainly doesn’t understand what freedom is, and probably doesn’t understand their own theory.

Rule 5: Any scientist who claims their theory shows that people are not conscious beings certainly doesn’t know what consciousness is, and probably doesn’t understand their own theory.

Rule 6: Any scientist who claims that their theory should be accepted because “everyone agrees” doesn’t understand what science is.

Rule 7: Anybody who refuses to specify the circumstances under which they would change their theories, beliefs or policies can leave the room now. This discussion is for practical grown-ups. (“Until a better one comes along” does not count.)

Rule 8: Any scientific explanation that blames the subject or patient can be rejected without further examination.

Rule 9: Any theory that only explains the past, and cannot predict the future, is a fact-based creation myth, not a scientific theory.

Rule 10: Any study paid for by an organisation should be accepted only if its conclusions are contrary to the interests of that organisation.

Rule 11: Any regularity, correlation or pattern discovered by number-crunching or statistical techniques should be treated as a curiosity until it is explained by some specific technology or institutional rules.

Rule 12: Any finding from a large-scale survey of people will always confuse cause and effect in such a way as to re-inforce the current social prejudices about those people.

Rule 13: Anyone who says “the plural of anecdote is not data” either doesn’t understand what the word “plural” means, or is trying to sell you their research services.

Rule 14: If the statistics say that 20% of the population do something, and you don’t know anyone who does, it’s not 20% of the whole population, it’s 100% of a smaller chunk of the population that nobody wants to identify out loud.

Rule 15: The source academic paper never says what the press release says it said. Unless it’s a sponsored study, when the academic paper says what the press release needed to say.

Rule 16: Anyone who doesn’t understand the various Quantum theories probably doesn’t understand what a Lie Algebra is. Fix that, and Quantum theories will suddenly become simple.

Rule 17: Anyone who says “logic dictates” doesn’t know that logic doesn’t dictate anything. It doesn’t even tell you how to draw conclusions from what you’ve just dictated. It just tells you how not to screw up drawing those conclusions.

Rule 18: Any popularisation of a scientific theory will distort and simplify the most important features of the theory in direct proportion to the intended sales of the book.

February / March 2015 Review

Cold. More cold. And more cold yet. I think I have worn my faithful Tyrwhitt grey houndstooth coat for four months straight now.

I read Hegel’s Philosophy of Mind, finished Heidegger’s Poetry, Language and Thought, Nevile Shute’s The Trustee from the Toolroom, Max Tegmark’s Our Mathematical Universe, William Byers’ How Mathematicians Think, Patricia Berman's In Another Light: Danish Painting in the Nineteenth Century, Howard Bloom’s The Lucifer Principle, Ian Fleming’s For Your Eyes Only, and Mark Lawrence's The King of Thorns. I think I read the Fleming when I was about eleven, and it clearly formed many of my opinions about Life, The Universe and Everything. I made a start on John Eliot Gardiner's book on J S Bach, and that's going to be read in several instalments this year.

I watched Inherent Vice, Hinterland, Appropriate Behaviour at the Curzon Soho; went with Sis and Mother to the Sargent exhibition at the NPL; had a Moroccan in Shepherds Market with Sis in February and fish at Kensington Place in March. We liked Kensington Place. On DVD I watched my way through the BBC’s Strangers and Brothers, The Event, and S1 of The Bridge.

I changed my work-outs to include 12-15 sets of 5 pull-ups with pyramiding supports: starting at 57 kgs (I weigh 97 *cough*) and dropping down to 50, 43, 36, 30, then going back up to 57 and back down to 43. Everything else I do is subordinate to that. I’m going to adding in some lat pull-downs, and may try the thing where you jump up to the bar and then let yourself down slowly. I did that once for a few reps: it ached for days afterwards.

Finally I got the beginning and end of my interminable Riemann-Roch essay sorted out, and now only have some stuff about Riemann surfaces to finish it off.

Then at the end of March I left a couple of pairs of trousers on the morning train that I had been intending to take for dry cleaning while I was on a planned six-day Easter break, which is passing with a seating, fever-y, nose-stuffing, cough-retching, sleep-depriving cold.

God hates me.

The Load Must Be Uniformly Distributed Between Hoppers

Fire Drill, Bishopsgate

Every day one or other of the office blocks in the City tips its occupants onto the streets. Companies with trading floors leave a couple of traders inside unless they know it's real fire and not a drill or some over-sensitive alarm. Then it takes about twenty minutes or so to get everyone back in and up to their floors.

(I know: I cheated the dates. The last weekend was weird and this week more so, involving cough and fever.)
