Technology in concert 6 May 2014

Two posts in one day … This one very brief.

We had the great pleasure, a couple of days ago, of hearing the great Canadian pianist Angela Hewitt perform in Glyndebourne as part of the Brighton Festival. J S Bach’s Art of Fugue appeals to the geek: it is strongly rooted in the systematic mathematical patterns of music, at which Bach excelled. Hewitt started with a short talk, and added enormously to our enjoyment of the music which she then settled to play, continuously, for almost two hours. A tour de force indeed.

OK, I get to do a very brief music review which isn’t a chance I get often. But like today’s other post (the Lego one), there’s a double link from something at first sight very non-IT into the world of technology.

Not just the structure of the music. But on the music stand of the piano I could clearly see an iPad or something quite like it. Printed music has been the same for around seven centuries, and has considerable advantages. Performers scribble on their scores to assist with performance, whether it’s members of an amateur choir such as the one we sing in, or high-end professional soloists who normally commit their music to memory before going on stage. But it has a big disadvantage in performance: someone has to turn the pages and this normally means an amanuensis sitting alongside in the concert hall.

I’ve wondered occasionally whether there exists performer’s software which could display music to play from, and turn pages automatically. Well, now I know. There is. It was just waiting for decent tablet computers to come along, which could be placed on the music stand instead of a paper copy.

And Angela Hewitt uses it. Why am I sure? Because I found a reference to it, with a picture, in a review of a concert she gave in Australia six months ago.

Only one development still needed. The performer needs a pedal to move the pages on. How about sound recognition so it would know when to move on without intervention? Though it would be difficult to handle repeats and so on.

Apple iPhone: the good and the dodgy 21 Apr 2011

Two reports on Apple this morning, both in the mainstream press.

Earnings have jumped, driven largely by the iPhone. The iPad is doing well, but has fallen back after the big Christmas rush. Apple assert that they have been able to manage the supply chain issues resulting from disruption in Japan (see Japan’s troubles touch the IT economy, 24 Mar), though there will be an effect on revenue; and that demand for the iPad2 is surging.

But reports also assert that the iPxxx poses a challenge to user privacy. The Guardian quotes analysts at O’Reilly Radar, one of InformationSpan’s favourite tech watch sources, who have shown that iOS4 automatically collects location data, stores the results in a file on the device, and replicates it unseen to the “home” computer when synchronised. There’s no opt-in or opt-out. The Guardian say that it has itself ascertained that the iPad also stores these data; and the information is transferred to a new device when the user migrates.

The privacy threat is twofold. First, from the data file: if the device is lost the file is hackable. Second, the data can also be unearthed on the synchronised computer.

O’Reilly says “Don’t panic”. It doesn’t appear that information is transmitted back to Apple. But the Guardian does point out that the iTunes conditions of service include the collection of location data “to improve location-based services”.

People trade privacy for benefit. But it needs to be an informed and active decision. And this is not going to decrease the already burgeoning fears (whether or not justified!) of IT Security professionals at the encroachment of these “unconventional devices” into the hitherto well-regulated corporate space.
