This week had risked turning into a disappointment, what with Richard Sennett’s lecture on “The Open City” being cancelled. But last night more than made up for it. The Data Insights Cambridge meetup group, er, met up, for a brilliant talk by Charlie Hull, founder of Flax, about open source search engines.

Instead of talking about how search engines are implemented, as fascinating as that stuff is, he largely talked about industry politics, which turns out to be fascinating too.

I was having a conversation the other day about a talk Alan Blackwell gave a couple of years back, about the history of the “Cambridge phenomenon”. This reminded me how, many moons ago, I attended a conference he organised entitled Collaboration and Ownership in the Digital Economy. It was about the possible wider cultural significance of challenges, in the software world, to entrenched ideas of intellectual property.

At the time I wrote a report on it, for my then employers. If only I’d had the foresight to keep a copy for myself…

I’ve forgotten much about it, but before I forget even more, here’s a brief review, a decade too late.

Architecture

This from Learning from Las Vegas, quoted in Edward R. Tufte’s classic The Visual Display of Quantitative Information (in the section about “self-promoting graphics”):

It is now time to reevaluate the once horrifying statement of John Ruskin that architecture is the decoration of construction, but we should append the warning of Pugin: It is all right to decorate a construction but never construct a decoration.

Rhetorical questions

Ian Pindar’s Guardian review of The Prince from a few years back:

Is it better to be loved or feared? Is it always necessary to keep one’s word? How can we avoid being hated? These are just some of the fascinating questions raised by Machiavelli in this classic treatise on statecraft, although, as Maurizio Viroli points out in his fine introduction, it is odd that an avowed republican should write a book of instruction for a prince. Is it in fact a satire designed to enlighten the masses? It’s a nice idea, but Machiavelli’s cynicism is all-embracing: in his eyes we are all “ungrateful, fickle simulators and deceivers, avoiders of danger and greedy for gain”. Peter Bondanella’s new translation is based on the best text available today, and he breaks up Machiavelli’s often long and convoluted sentences to clarify his ideas. It’s well worth £3.99 of anyone’s money, and the answers to the opening questions are (1) feared (2) no, and (3) refrain from being rapacious and usurping the property and women of your subjects.

Matthew Stewart, The Management Myth:

The recognition that management theory is a sadly neglected subdiscipline of philosophy began with an experience of déjà vu. As I plowed through my shelfload of bad management books, I beheld a discipline that consists mainly of unverifiable propositions and cryptic anecdotes, is rarely if ever held accountable, and produces an inordinate number of catastrophically bad writers. It was all too familiar. There are, however, at least two crucial differences between philosophers and their wayward cousins. The first and most important is that philosophers are much better at knowing what they don’t know. The second is money. In a sense, management theory is what happens to philosophers when you pay them too much.

Related to this, from Einstein’s Clocks, Poincaré’s Maps by Peter Galison:

Over the last thirty years it has become a commonplace to pit bottom-up against top-down explanations. Neither will do in accounting for time. A medieval saying aimed at capturing the links between alchemy and astronomy put it this way: in looking down, we see up; in looking up, we see down. That vision of knowledge serves us well. For in looking down (to the electromagnetically regulated clock networks) we see up: to images of empire, metaphysics, and civil society. In looking up (to the philosophy of Einstein and Poincaré’s procedural concepts of time, space, and simultaneity) we see down: to the wires, gears, and pulses passing through the Bern patent office and the Paris Bureau of Longitude. We find metaphysics in machines, and machines in metaphysics. Modernity, just in time.

SDBM

I’ve been a bit slow in my learning of Ruby. This time around I’ve re-written Ozan Yigit’s ndbm clone: sdbm.

I’ve cheated a bit. My general plan has been to pick things up through re-writing bits of existing code in Ruby: but to do them from memory (swotting up if necessary) rather than translate them directly. In this particular case it was convenient (for testing) to ensure that my implementation produced files that were bit-for-bit identical to those produced by the original (as incorporated into Perl). So, to avoid incompatibilities, I wrote down the string hash algorithm and the block sizes used for reading and writing the files. It was only a tiny cheat.

Top-down stickiness

Mathematics as Sign, Brian Rotman, pp112-113:

What would top-down over bottom-up—as an intellectual method, organizing metaphor, or cognitive style—mean? One might gloss it as the ranking of the global, panoptic, abstractly analytic over the concrete, limited, and locally synthetic; of posterior description, morphology, and structure over history, evolution, and genesis; of plans over objectives and goals; of general laws over incidents and cases; of context-free reason over situated knowledge; of realist truth over constructive emergence. But the figure is also reflexive and applies at once to descriptions of itself; the summary I have just given (which is perhaps less than helpful as an explication) is very much a top-down take on the top-down / bottom-up difference.

Michael Oakenshot—an introduction, Paul Franco, p12:

Nevertheless, despite many similarities between Hayek’s critique of central social planning and his own, Oakeshott criticized The Road to Serfdom for ultimately being too ideological. The main significance of Hayek’s book, he wrote, is “not the cogency of the doctrine, but the fact that it is a doctrine. A plan to resist all planning may be better than it’s opposite, but it belongs to the same style of politics.”

Michael Oakenshot—an introduction, Paul Franco, pp177-178:

The dominant idea of Berlin’s philosophy is, of course, value pluralism. Almost everthing he wrote, from The Hedgehog and the Fox (1953) to The Pursuit of the Ideal (1988), involves an attack on monism … and a defense of pluralism … So prevalent is this master dichotomy in Berlin’s thought that is can become rather monotonous. And as many commentators have noted, though Berlin identifies with the fox who knows many things, he himself turns out to be something of a hedgehog who knows one big thing: that values are plural, and that rationalistic monism is a mistake.

Frank Stajano’s presentation on security (and the recent Cambridge Stack Overflow Dev Day) was based on the premise that hustlers and scammers understand human psychology in a way that engineers do not, and so security engineers would do well to learn from how classic scams work.
