In many of my conversations about the dreadful risks of AI, I find myself laughing involuntarily. “AI is wrecking education, but it doesn’t matter too much because there won’t be jobs for these kids anyway, hahaha. Or else misaligned superintelligence will kill us all, hohoho.”

My personal computing device was a laptop I bought in 2016 when I left Mozilla. It still works well, but after 9 years I thought it was reasonable to buy a new machine. I don’t game much but when I do I’d like to be able to play modern games. I like to do some software development on my personal machine, and when I was working on LLDB it was very painful on the old laptop.

Last weekend I took a long weekend, Friday to Monday, to do the Tongariro Northern Circuit again. This time we had great weather and our group of 12 had a great time!

I went camping at Pararaha Valley again! This time I didn’t have any of my kids with me, but I went with a few friends who brought their kids. It was once again an excellent trip.

At the end of our Queen Charlotte track trip, most of the group headed to Blenheim to fly back to Auckland or pursue their own plans. Five of us took a shuttle to Nelson for a day off, then joined four others for another five-day trip exploring southern Kahurangi National Park.

Over the last couple of weeks I did my annual South Island tramping trips. This year we started with the Queen Charlotte Track in the Marlborough Sounds, which I previously did in 2014.

This morning, I once again ran the Auckland Half Marathon — just under 2 hours.

I spent most of September traveling, partly in order to deliver a keynote at the DEBT debugging workshop in Vienna (associated with ECOOP). My goal was to inform people that “advanced” debugging technologies like record-and-replay and omniscience exist, they are being used in practice, and that use is increasing; and to explain what has been successful and what has not, and what I think we need to do to be more successful. There was no recording and I can’t share the slides so here’s my summary.

Previously we’ve had some great trips during the winter to Waihohonu Hut in Tongariro National Park in the central North Island, so I planned another one for this year. It went really well!
