2015 MacBook Air, 2026 version

In 2024, we took our first return trip to Malaysia since the 1990 s. We thought we might need a laptop for the trip, so I picked up a 2015 MacBook Air. Soldered memory, unfortunately, so the 8GB max was all we were going to get, and a 128GB disk. Somehow we managed to cram enough [ ]

Writing as Music

I subscribe to Recommendo, a mailing list from Kevin Kelly and Mark Frauenfelder. I used to read Boing Boing a lot for interesting stuff; I just took a peek and it s mostly trivia now. Admittedly, some is interesting. (The sea permanently changing color in 1907 was a new one.) Generally, it hasn t had much for [ ]

Checkpoint

A quick summary of a bunch of stuff I ve done lately. Probably more, but that s what I remember.

Shaping up

The last few days have been devoted to other things like dental emergencies, but the app continues to shape up. I discovered that expecting live activities to do much beyond show you something and open the app if you tapped them is quite fragile and can make things very complicated. Switching that over to just [ ]

Bladder training app progress

I ve gotten to a decent beta at this point, and I m eating my own dogfood: my urologist put me on bladder training with a two-hour interval, so the app is set up with that as the default interval. I ve been testing it as I go along and added a few things that I needed: Running [ ]

Not an app I thought I’d need, but here we are

sd1diskutil: Resurrecting a disk format from the dead for a brand-new emulator

A little history The Ensoniq SD-1 is a synthesizer from the 1990s — a ROMpler with a Motorola 68000 at its heart. Like many synthesizers of the era, it uses the cheap, easy, and simple storage medium of the day: 800K floppy disks for storage of everything: factory programs, user programs, presets (organized small sets [ ]

Brachytheraphy, Pluvicto, and decay curves

Earlier in the year, I had LDR (low-dose) brachytherapy treatment for prostate cancer. The way it works is that the radiation oncologist, in concert with the urologist/surgeon, maps out where the cancer is in the prostate, and then builds up a map in 3D of exactly where to implant a set of radioactive seeds to [ ]

The Podcast Repair Kit

A quick way to build, enhance, and repair your podcast episodes Introduction This all started when I was repairing a screwed-up Azuracast installation. I deinstalled and followed the do this to remove the old volumes instructions. That blew away all my stations and all my podcasts. Yes. it was early in the morning. Yes, I [ ]

How not to repair your Azuracast

Recently, we ve been working on trying to build some tooling to make our Azuracast experience for our DJs and listeners a little better. Shooting myself in the foot: background We ve been trying to work around a longstanding bug: when a new streamer connects to Azuracast, Azuracast s Liquidsoap processing picks up the last thing the previous [ ]
