Home-made DVDs of our travels and family events were backed up as disk images (.dmg) onto an external hard drive as they were made. When these were inadvertently deleted I attempted to re-create the backup using Disk Utility to create new disk images. I was very concerned to find that about a third of my collection would either fail to mount on the OS X desktop or, if so, caused Disk Utility to report an input/ output error resulting in failure to copy. So what gives Apple? Why can my Mac not mount, copy, or play back Mac-made DVDs—when my consumer player handles them fine?

As reported by Ars Technica, the New Zealand House of Representatives passed a bill on 8 April 2008 reforming copyright law for the "digital age". Most netizens even outside the US will have come across the American DMCA: any mention seems tainted by the taste of bile. The DMCA criminalises circumvention of digital rights management (DRM) technologies and access controls—many folk argue at the expense of "fair use". Do the NZ reforms provide workable compromise?

As noted, we were recently in Brazil. We also crossed into Argentina for a day, in order to view the Iguazu Falls from their side of the Rio Iguazu. The falls are probably the single most impressive natural phenomenon we've seen.

Now that the expensive but excellent Firewire-based iSight is no more, Mac users lacking a built-in (USB-based) iSight webcam face a dilemma. Although Mac OS X 10.4.9 introduced iChat support for USB Video Class (UVC), and using such webcams means no extra drivers are needed, it is far from easy to walk into a store and choose a one that is certain to work. I threw my once-loved Cyberphone, blaming the non-native drivers for poor audio performance on my Intel Mac. Any cheap webcam (as with the Cyberphone) is likely to have poor Mac driver support, so a driver-free UVC camera seemed like the answer. But would the built-in microphone be recognised? Google didn't seem to come up with a definitive answer to this question. Furthermore, reports said that Vista-certified cameras "should" work—but elsewhere I read that some Vista-certified webcams support UVC and others do not. So how can you send high-quality Skype video and audio without hogging all your USB ports?

As reported by the BBC, a general practice in Wales has begun using YouTube to distribute health information videos. The Builth and Llanwrtyd Medical Practice has thus far uploaded videos relating to inhaler technique and spacer devices in respiratory disease, having a smear, and blood sugar testing in diabetes.

I haven't paid much attention to YouTube—until now. There was a song on the vid screens at the gym by a New Zealand artist I'd not come across, and a Google search led me to the video on YouTube. I decided to see what else was there. Some of the videos available are for songs I currently love (q.v. Bic Runga) but never got to see the video for until now (maybe they weren't on UK TV). But there are also old favourites to remember and new discoveries to appreciate. Here are a few personal highlights from the past 3 decades: enjoy!
