Day 7 was pretty tough, I initially ended up implementing an exponential in both time and memory solution that I killed because it was eating all the resources on my Mac Studio, and this poor little machine only has 32GB of memory (I stopped it at 118GB of memory, swapping badly!), This is what I ended up doing before/after:
- Before: Time O(2^k · L), memory O(2^k), where k is the number of splitters along a reachable path and L is path length. Exponential in k.
- After: Time O(R·C) (or O(R·C + s) with s split events), memory O©, where R = rows, C = columns. Polynomial/linear in grid size.
Awk to take lines from Plan 9’s /lib/unicode and prepend the actual glyph and a tab: awk ‘{cmd=sprintf(“unicode %s”, $1); cmd | getline c; printf(“%s %s\n”, c, $0)}’

I had no meetings this arvo, so I made an appointment with the woods in my extended lunch break. The 6°C warm sun was out all day long and there was only a very light breeze. So, a very nice autumn day.
When I stopped to take a photo in the forest, a deer behind me took off into the woodland. I didn’t see it before. Also, I came across one or the other clearing. Sadly, it’s all commercial timberland here. Luckily, in a year or so, when nature slowly took over and reclaimed some spots, the apocalyptic sites are then looking a bit more decent again.
Cleaning of the ruin walls on my backyard mountain slowly takes shape. They made some progress and moved on to the other section. The flag on top is halfway disintegrated again, all the yellow half is completely gone. I’m wondering if they just stop replacing it at some point in time. But probably not.

There are no really good GUI toolkits for Linux, are there?
⤋ Read More
FTR, I see one (two) issues with PyQt6, sadly:
- The PyQt6 docs appear to be mostly auto-generated from the C++ docs. And they contain many errors or broken examples (due to the auto-conversion). I found this relatively unpleasent to work with.
- (Until Python finally gets rid of the Global Interpreter Lock properly, it’s not really suited for GUI programs anyway – in my opinion. You can’t offload anything to a second thread, because the whole program is still single-threaded. This would have made my fractal rendering program impossible, for example.)
