People (and not only students… who actually are also people ;-)) frequently ask me what fundamental computer related skills are necessary for developing a Digital Arts activity/career.
An excellent answer is given by Golan Levin in this video.
I summarize it here:
- learn a text based computer language (e.g. Java/Processing, C/C++/ObjC/OpenFrameworks, etc);
- learn a patch based computer language (e.g. PureData, MAX/MSP, etc);
- learn a micro-controller programming environment (e.g. Arduino, Raspberry Pi, BeagleBoard (which are actually true PCs in a board, and not simple controller boards);
- learn how to use a video editing suite (e.g. iMovie, FinalCut, Premier, etc);
- learn how to model using a 3D modeling app (e.g. Google SketchUp, Blender, Maya, 3D Studio Max, Cinema4D, etc);
- learn how to manipulate audio (e.g. Audacity, Sonic Visualizer, Adobe Audition, Apple Logic, Protools, etc) – this one was added by me 😉
Anyway, these are the days where technology is, as it probably never was, at the service of creative (and artistic) minds. So, “just do it” [Nike, 1988], and “yes, we can” [Obama, 2008]! 😉
A good description of the differences and usage of these two useful command line tools.
I couldn’t agree more with this idea of open source as mandatory for reproducible science.
It’s like github for open source hardware
The above link points to an excellent talk by Herb Sutter (Microsoft Research) on the real advantages of C and C++ (and Objective C! – all known as “native” languages) in what concerns performance per $, per Watt, per transistor and per cycle.
And it’s not just on mobile platforms – he shows that “The world is built on… C/C++”: servers, desktops, mobile platforms and large scale data centers (talk about C++ being an eco-friendly language! :-)).
So, I’m glad to see the start of an age of the “return of the King”, which will not only last for the next decade, but will perdure even more when Moore’s law finally gets to an end.
Managed languages (i.e. Java, C#, etc) still have their place where “productivity” is key (which does not seem so much the priority nowadays – not even in the foreseeable future, so they say – and in case you still believe in the myth that those managed languages are as speedy as C/C++, have a look at this paper), but I’m glad that we finally got enough of it (it took almost 10 years of waste and stalling!!), where they were used as a hammer to solve any problem, which had first to be turned into something resembling a nail (just look at what happened to the Windows Vista fiasco and its C#/.Net managed code base… but not all was bad in Vista – a good lesson was learned… the hard way, but those are the lessons that usually become persistent for generations to come… hopefully ;-)).
we are on the verge of finally getting we already have the brand new C++ standard, C++11, which includes quite some exciting new features for C++, making it an even more exciting language to program with. Add to that the new impressive developments in the LLVM/Clang toolchain, and you start seeing the killer combos we are getting nowadays for native development.
So, these are exciting times for C/C++/ObjC folks, and computing in general. Glad to see Apple, Google and Microsoft (among others) really betting all their game on these native languages and investing a lot on taking the best out of them.
I’ve always believed in the power of C/C++/ObjC, even when a lot of people became fully fascinated with all those fancy new managed languages and looked at the folks still coding in native world as a bunch of old weirdos stuck into some “obsolete” and “uncool” language universe.
Well, I started my programming career back in 1996 coding in assembly for DSP chips (TI C3x, C6x series and AD Shark – already floating point chips, which later on started having some basic C support). So my starting point may be a bit different from most of these younger folks. And maybe that’s why I anticipated that the days where efficiency would eventually become king once again would not be far – it was just a matter of “when”, instead of “if”. Glad to see that the “when” is finally “here”. 🙂
Excellent Radio Program/podcast about patents in the USA (which kind of follows a Michael Moore documentary style and approach ;-)).
In general, I have strong reservations on how patents are issued in the US. In particular, software patents are something that really surpass my comprehension and so far in Europe we have been safe from such a plague (not sure for how long, though… the lobby is strong and our european politicians are kind of weak…).
Patent trolls subverted the patent original idea of protecting IP for inventors who come up with original and non-trivial proposals, and I’m inclined to think that such patent troll people/entities/corporations do more harm than good to innovation in a global worldwide scale…
I should at some point try to understand what is the portuguese scene in what regards patents and promote debate and discussion on these important topics that have such a strong impact on research, innovation and entrepreneurship. I’ll keep you posted.
For anyone interested on this topics, a good resource to follow is Techdirt blog/forum.
Really nice interview with Bill Buxton, during CHI2011 conference, where he exhibited his impressive collection of gadgets that range from watches, to all sorts of joysticks and hand held devices.
By the way, Microsoft Research and Bill Buxton are compiling this impressive and valuable collection on a website that is a mandatory study reference for anyone studying/working on HCI, Interfaces and Interaction. The site includes detailed photos, descriptions and comments by Bill himself and videos of the working user interfaces and how some of the devices operate are being uploaded into the website.
So, before you dare to present any “novel” interface/interaction design/HCI solution to the world, just follow Bill’s advice and check first if someone else already proposed that same approach some years ago (and save yourself from some embarrassment ;-)).
