Videolab is an educational software piece that teaches and lets users experiment with concepts of digital video technology. It can be used standalone by students or as a lecturing tool by instructors.

I developed this Educational Software project as part of the coursework required for my Digital Media PhD, but I hope it’ll come handy in my own teaching. This prototype was made with Processing 2.08b and was thoroughly tested on Windows, but should work on other systems as well.

These are some of my early experiments with slit-scan photography, made while trying a Processing application I coded mostly as a learning exercise. The software allows you to either 'scan' your webcam image or a video file, but since using my laptop as camera is a bit cumbersome, most of the above images were made by 'scanning' some random videos I had around. I'll have to try to shoot video specifically for slit-scanning — so far I found out that stable, sideways shots of slow-moving subjects work the best. (As an aside, slit-scan photography is basically one of the main techniques used by Photo-finish systems, only at very high frame rates.)

Anyway, I think the app is cool and stable enough to be worth sharing, so I made a download for Windows available — head to my Processing sketches page to get it!

Bruce Sterling’s essay on the New Aesthetic. This is an interesting read, even if it did nothing to counter my ambivalent feelings towards the New Aesthetic. On one hand, I like it, the idea. Even if the ‘official’ blog — which I follow — feels a lot more random than a ‘movement’ should (but perhaps I’m mistaken in expecting something like a ‘movement’). I like to think that at last we figured out an aesthetic for the early twenty-first century, that it is our generation’s Futurism, this time centered in CCTV-obsessed Britain rather than in automobile-obsessed Italy. On the other hand though, I may also believe the New Aesthetic is just a bandwagon, a neatly packaged brand for journalists and lazy curators and critics. Consider John Whitney. BEFLIX. The demoscene. The comparatively long history of Glitch art. Software art. Consider Thomas Ruff’s eroded JPEGs touring the world’s art museums (museums!). Cory Archangel’s tweets about 1990s ‘New Aesthetics’. From this perspective, the New Aesthetic seems like a brand invented by the same kind of savvy people who came up with concepts such as ‘creative industries’ and made a killing living off artists and craftspersons. But then again, most art ‘movements’ didn’t ever exist as such. ···

Journalist Alexis Madrigal calls for a post-Facebook future (mind you, what the article is really about is the increasingly diminished returns of social and mobile software). I’m all for new things, but the current situation was expected after the initial push to develop applications that leverage ubiquous broadband internet and mobile hardware with built-in sensors (mainly camera and location/GPS) pretty much consolidated. I think that now is time to take a deep breath and start figuring out what happened, what worked and why, and what it means. Bring in the academics. ···

One Terabyte of Kilobyte Age. The authors, Olia and Dagan, blog interesting stuff found in the Geocities torrent rescued by Archive Team. Funny I can’t even remember what was my old Geocities address. ···

PHP: a fractal of bad design is a very thorough critique of everything that is wrong with the programming language. However, I don’t believe it is constructive to attack PHP developers (such as your truly) as an horde of illiterate, masochistic fools that refuse to use proper tools. Such attacks grossly underestimate the pull of PHP’s being a good enough language for web development — incredibly easy (eg. XAMPP) to get into, well documented, and widely supported by cheap web hosting providers. It’s flawed (eg. I must reemphasize the ‘well documented’ aspect of PHP’s success, given how unintuitive its function names are sometimes) but allows me to do a quick ‘sketch’ of a webpage, hit ‘refresh’ and (often enough) voilá!, it works. And it is this ‘sketching’ (a word I’m borrowing from Processing) aspect that I find vital. To go with the author’s carpenting analogies, most people are building small houses — maybe a shed, maybe a greenhouse to keep the flowers. They don’t need complicated ‘scaffolding’ like in Ruby or Python frameworks. They just need to be able to sketch. ···

An economist’s Six Rules for Dining Out. Some of his tips seem pretty universal: seemingly strange dishes at fancy restaurants must exist for a reason and are probably quite good; listening to lots of conversation means people are waiting a lot more than eating (so loud restaurants should be skipped); and dining establishments in very good locations (eg. with lots of tourists) afford to be bad and expensive, and should often be avoided. ···

Metafilter’s Year in Writing has given me much to read in the past and coming weeks… ···

Our Unpaid, Shadow Work: you know that last time you bought a ticket online? Or yesterday when you filled your car with gasoline yourself? Or when you went to the supermarket and scanned your own groceries’ barcodes? You are doing someone else’s job, for free. Sure, you get cheaper tickets, gasoline or groceries because of that (do you really?), but that’s no way to run a proper economy. ···

Makimizing shareholder value is the dumbest idea in the world. This is a headline on Forbes!, not The Communist Workers’ Union Monthly or something like that. ···

Two interesting articles about fighting cognitive biases and other kinds of self-delusion: Steven Pinker would ban the idealization of the past if he happened to rule the world, while Freeman Dyson reviews Daniel Kahneman’s statistical approach to psychology. ···

Umberto Eco’s guide to identifying fascists, written in 1995, makes the future look rather bleak. ···

Roger Ebert tells us why movie revenue is falling. I’d say what’s surprising is that movie revenue is holding so well, at least here in Portugal. Mini-rant: Even though I’m rather able to concentrate when I go to the movies and cope rather well with other patrons’ poor civics, I find it anoying that going to the movies means quite often driving to a shopping mall in the suburbs, eating overpriced mall food, standing in line for too long to buy tickets, etecetra, the alternative being a couple of inner-city theatres that offer nothing else but waiting out in the cold, or an extremely overpriced and unconfortable bar. Please make the theatres places where people would actually enjoy hanging out, else they’ll be downloading movies off the internet and watching them at home — not because it’s cheaper but because it is better. ···

Peyton’s Place: An interesting essay about what it’s like to lend one’s house to a TV series’ production. It didn’t go well. ···

KidsRuby seems like an interesting tool to teach programming. And not just to kids. Similar tools using Ruby (which, from my very shallow knowledge of it, really seems the general-purpose language with the simplest syntax) include Hackety Hack and the very cool Shoes. ···

The fiction of the creative industries by Florian Cramer. From a Dutch perspective but translates well into the Portuguese reality. The gist of it — the ‘creative industries’ hype conceals centralism (and nepotism) under a veneer of advertising, and harms both non-profit Art and independent creative businesses. Agreed!
