Different things I find interesting about computers and technology.

New Master’s Programme: Music, Communication & Technology

We are happy to announce that “Music, Communication & Technology” will be the very first joint degree between NTNU and UiO, the two biggest universities in Norway. The programme is now approved by the UiO board and will soon be approved by the NTNU board.

This is a different Master’s programme. Music is at the core, but the scope is larger. The students will be educated as technological humanists, with technical, reflective and aesthetic skills. We believe that the solutions to tomorrow’s societal challenges need to be based on intimate links between technological competence, musical sensibility, humanistic reflection, and a creative sense.

A core feature of the programme is the unique two-campus design. The student group is physically split between Oslo and Trondheim, 500 kilometres apart, but with a high-quality, network-based multimedia connection that allows for discussions, socialising and playing music. As a student you will get hands-on experience with state-of-the-art facilities, including motion capture systems, music production studios, and large loudspeaker arrays. The theoretical components include acoustics, music cognition, machine learning and human-computer interaction.

New publication: “From experimental music technology to clinical tool”

Omslag_Ryhme-smallI have written a chapter called From experimental music technology to clinical tool in the newly published anthology Music, Health, Technology and Design, edited by Karette A. Stensæth from the Norwegian Academy of Music. Here is the summary of the book:

This anthology presents a compilation of articles that explore the many intersections of music, health, technology and design. The first and largest part of the book includes articles deriving from the multidisciplinary research project called RHYME (www.rhyme.no). They engage with the study of the design, development, and use of digital and musical ‘co-creative tangibles’ for the potential health benefit of families with a child having physical or mental needs.

And here is the abstract of my chapter:

Human body motion is integral to all parts of musical experience, from performance to
perception. But how is it possible to study body motion in a systematic manner? This
article presents a set of video-based visualisation techniques developed for the analysis
of music-related body motion, including motion images, motion-history images and
motiongrams. It includes examples of how these techniques have been used in studies of
music and dance performances, and how they, quite unexpectedly, have become useful
in laboratory experiments on ADHD and clinical studies of CP. Finally, it includes
reflections regarding what music researchers can contribute to the study of human
motion and behaviour in general.

Many applications that do few things or a few applications doing everything?

To follow up on my previous post about the differences between browser plugins, web interfaces and desktop applications, here is another post about my current rethinking of computer habits.

In fact, I started writing this post a couple of months ago, when I decided to move back to using Apple Mail as my main e-mail application again. I had used Mail for a few years when I decided to test out Thunderbird last year. The most important reason for the change was the poor search functionality in Mail. True, the search function is fast, but it is very limited if you are looking for specific things. Thunderbird 3 has an improved search function with a very nice calendar view, so this seemed very tempting. Besides functionality, choosing Thunderbird over Mail was also an ideological one, since I wanted to try out using free software for all my main desktop application needs. More about that another time.

Unfortunately, Thunderbird just didn’t feel snappy enough. I am not sure if the application really is that much slower to work with than Mail, but at least it felt like that. And while I love the search functionality, it also feels too slow to work with. But rather than moving straight back to Mail, I decided to make a detour around Opera. Luckily, switching back and forth between e-mail clients is no hazzle at all when using IMAP, as compared to POP.

I used to use Opera for e-mails back in the days when MS Windows was my main OS, but hadn’t tried it in many years. The really nice thing about Opera is how they manage to put all sorts of things into one single application: browser, e-mail client, RSS reader, web server, ftp, bittorrent, widgets, presentations, etc. Even with all that stuff packed in it feels like a fast application to work with.

But, doing everything with Opera for a few weeks led me to the techno-philosophical question: is it better to use many applications that do few things or few applications that do many things?

In one way I really want to like Opera. But after working with it for a few weeks I am not fully satisfied. While it is certainly compelling to have one program that can do it all, and even sync it all between multiple computers, it is also dangerous.

For example, for a while I have tried to not open my e-mail application before lunch. My brain works best in the morning, so I try to set aside some quality research time in the mornings. For this I often need a web browser, but not an e-mail client. Using Opera for both just doesn’t work.

Another thing that I always think could be very useful, is to read RSS-feeds within the same program that I read e-mails. However, even though this is possible in Opera (and in Mail and Thunderbird), I have never really been comfortable with the combination. I guess it is because reading RSS-feeds is like reading a newspaper or magazine. It is “passive” in the sense that I am only receiving information. Checking e-mail, on the other hand, is an active process where I delete, reply, forward etc. Again, I realize that it is actually quite nice to have separate applications handling these quite different activities. Another reason for this is that I have grown so used to NetNewsWire (which also syncs nicely with the iPhone), a dedicated application that is functionality-rich, yet super-snappy to work with.

The same goes for many other things I am doing during the day, e.g. taking notes (Journler), handling to-do lists (Things), etc.

So my conclusion is that I prefer having separate, dedicated applications for each of the different tasks I am doing.  While, it is possible to get it all in one (e.g. Opera or Firefox loaded up with add-ons), I really prefer my many small programs doing their little things really well.

What to choose: Browser plugin, web interface, desktop application?

Nowadays I have a hard time deciding on what type of application to use. Only a few years back I would use desktop applications for most things, but with the growing amount of decent web 2.0 “applications” I notice that I have slowly moved towards doing more and more online.

Let me use this blog as an example. It is based on WordPress, which now offers a good and efficient web interface. However, it just doesn’t feel as snappy as a desktop application. A few years back I used MarsEdit for all my blog writing, but for some reason (I can’t remember exactly when) I decided to use the WordPress web interface for blog writing instead.

Last year I discovered ScribeFire, a browser plugin available for FireFox, Chrome and Safari. I have been quite happy with ScribeFire, as it is readily available in the browser. The fact that it also allows for editing the static pages, as well as handling image uploads makes it into a really powerful solution.

However, today I opened my old version of MarsEdit by accident, and I actually realized that I have missed having a decent blog editor for the last couple of years. Even though the WordPress web interface, and the ScribeFire plugins both behave well and do (almost) all I want, they still can’t compete with a native desktop application when it comes to snappiness and functionality. So now I am back to MarsEdit, and happy to see that it finally has support for rich text editing in the latest version. I will probably use the other alternatives to, but I realize that desktop applications still have their mission.

Boot problems Ubuntu 10.04

Just as I started to believe that Ubuntu had matured to become a super-stable and grandma-friendly OS, I got an unexpected black screen on boot of Ubuntu 10.04 on a Dell Latitude D400. After some googling I have found a solution that works:

On boot, hit the `e’ button when the grub menu shows up. Then add the following after “quiet splash”: i915.modeset=1

If this works and you get into the system, you can do this procedure to change the grub loader permanently:

  • sudo gedit /etc/default/grub
  • Find this line: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash” and replace with: GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash i915.modeset=1”
  • Finally do a sudo update-grub to re-generate the grub menu

I hope this can help save an hour or two for other people encountering the same problem.
