Here's a proper miscellaneous topic: The contents of a box of cameras passed down through my family. Ilford Sportsman, Zeiss Ikon Colora, Agfa Super Silette L I thought of these as "granny's cameras" — my paternal grandmother was quite a keen photographer — but it turns out they came from a couple of different family… Continue reading Three cameras from around 1960
On picking up the cello again after 30 years
For most of the last 30 years I've had a cello sitting in a case in a corner of the flat, unplayed. I described myself as a lapsed cellist, former cellist, sort-of cello player when younger, someone who is just not really playing these days. Occasionally I would get the cello out and tune it.… Continue reading On picking up the cello again after 30 years

In version 3.0 we introduced a totally new, higher-quality processing engine, which I'll refer to as the R3 engine. The older one is still included, and I'll call that R2. Although the output of R3… Continue reading Performance improvements in Rubber Band Library

For as long I can remember, the behaviour of more when run on a text file shorter… Continue reading A note on the paging behaviour of more(1) in util-linux 2.38
Note on “Explorations in Time-Frequency Analysis” by Patrick Flandrin
Patrick Flandrin is a physicist and signal-processing researcher whose name I first encountered as co-author (with François Auger) of a 1995 IEEE Transactions on Signal Processing paper called "Improving the Readability of Time-Frequency and Time-Scale Representations by the Reassignment Method". This crunchy publication (21 pages, dozens of equations and figures) took a pleasing idea —… Continue reading Note on “Explorations in Time-Frequency Analysis” by Patrick Flandrin
