Seaside sunrise at the end of July.
Process: In GNU IMP: downscale photo to 10%, convert to indexed palette with 6 colours, convert back to RGB, perform edge detection with Laplace operator (border policy white), invert colours, threshold at (1,255) to black and white (as much white as possible). Then save as PPM and run potrace from the command line, without any options, giving an EPS file with the same stem. Load this back into GNU IMP, at 600dpi with strong antialiasing settings. Downscale to 720p greyscale JPEG for web, keep the high resolution for printing (445dpi fits nicely on A4 paper, with 15mm border on left/right/top (bigger bottom border).
Working on some music stuff, thinking of algorithms that might work nicely on an #Amiga #A500 or #A500Plus (currently implemented in C on a modern machine, but it uses 16bit integer maths for the most part, probably needs optimisations to replace divisions with faster things).
There are 3 tables of 16384 signed 8-bit audio data, which get repeatedly filtered in-place by some hacky moving average stuff while they are played in a loop.
For the final version I'll probably end up reimplementing it in inline-assembler in Amiga E.
- store zoom out sequence was saving JPEG contents in PNG filenames sometimes
- store zoom out sequence was forcing some kind of center reuse even when not requested (reported by saka and Azula)
- store zoom out sequence was sometimes not saving metadata in image files correctly
- setting bad SIMD vector size in KFS could crash (reported by FractalAlex)
- setting window size/image size from KFS should be better behaved now
- refactor default loading (now it loads default location kf.kfr from next to EXE, as well as default settings kf.kfs; defaults are only loaded when respective command line options are not given)
- don't recalculate fractal when changing window size (reported by FK68)
- fix buffer overflow crash in iterdiv -> string for GUI, also fix loss of precision (reported by FK68)
- fix typos causing last few pixels to be corrupt in SIMD
- remove annoying dialogs about derivatives (requested by gerrit)
- upgrade to boost 1.73.0
- upgrade to mpfr 4.1.0
- upgrade to tiff 4.1.0
- upgrade to glm 0.9.9.8
- upgrade to openexr 2.4.2
- don't upgrade to pixman 0.40.0 ( https://gitlab.freedesktop.org/pixman/pixman/-/issues/43 )
problematic language in tech
I was instinctively starting to write "webmaster" but replaced it with "website editor" in an email today, feels less "snappy", but the page I was emailing about had an "editor login" button on it so I think it was a better term to use, moreover the address I was writing to was a general "contact us" address, not necessarily a sysadmin.
> If you're in the northern hemisphere, and gazing up at the right moment – around 4am local time, July 10 to 15, looking northeast; and potentially an hour after sunset, July 14 to 23, looking northwest – you should catch a glimpse of the comet, C/2020 F3 NEOWISE. And local time really does mean the time wherever you are.

> Dear All, finally the Proceedings are completed. All your papers (ICLC2020) are now published individually on Zenodo. A quick search on zenodo with your name or title of the paper should direct you there easily. I have listed them at the bottom of this message too.
> I have also compiled a full book of the Proceedings which contains all the papers, posters, workshops, installations and concerts notes and very nice photos of the three wonderful days we spent together:
> Please share this message widely on social networks (I have no account on FB TW ... anymore)
> Enjoy and I hope to see you soon

Old desktop computer, 2011 era, was making a lot of rattling noise. So I got a new CPU fan. Didn't fix it. Took out the GPU, cleaned its fan of all the dust, put it back in. Noise still present. Took out the GPU again, turns out it is actually some other fan making the noise: remaining suspects include case fans (one of which is definitely not the issue), or the power supply fan (most likely) making the noise :(
Definitely not sure I want to take apart a PSU to investigate/repair, those capacitors look big.
Oh, the page has changed since I posted the link. Here's the image that was on the page. (BBC credited it to Reuters).
I fixed #Bolsonaro 's mask.
