I did not realise I had strong feelings on docstrings. I use them sparingly, and while they are a hack, at least they serve a good purpose.
I know people have opinions on the placement of line breaks and quotes, but I thought I was above these things. That this was Python programmers yearning for curly-brace level style wars.
I was mistaken.
I just encountered docstrings written in regular quotes rather than triple quotes and, no, apparently I DO have strong feelings on docstrings.

Looking for a laptop for my (very cool, she's having me tell you) sister who is about to start uni. So on the light side (and 14"), should last a good number of years, and be able to run stuff like Krita and CAD tools.
I'm probably looking at Lenovo or Dell by default, but any recs welcome. What would y'all go for in terms of memory and power? 16g enough?

in (trad, nobody uses it) IT German, a stack is called a "cellar", which always struck me as ridiculous: it doesn't fit what's going on at all. like, what is the commonality with a stack – is it that you can put stuff in and take it out again? absurd
(it's not even badly translated, it's an original term, patented in the 50s)
however, I do think using names that illustrate what's going on is a great idea to make things more memorable
so anyways, a doubly linked list is now a paternoster

I'm still sad that phone cards aren't a thing anymore for the weird art you got to carry around with you, and any local train company providing physical Deutschlandticket cards should get on that imo.

Ugh, just saw the new #wrapstodon feature that adds a “Year in Review” to Mastodon – it’s up on mastodon.social already, and will be part of v4.4.0.
It’s super number-go-up brain: You’re part of the top x % of Mastodon users! You had so many new followers and posts!
Plus a super cringe and unnecessary “We won’t tell Bernie” message under the top-% stat. Jfc.
I opened an issue asking to let server administrators turn this off before it even starts: https://github.com/mastodon/mastodon/issues/33150

I’ve finally caved and wrote an auto moderator for Mastodon that can take care of some reports automatically.
Running it manually for now to see if it works as intended, but I think this will be a net positive for us. Watch this space 👀 #mastoadmin

it’s cold and gloomy, so it’s time to knit something warm and cozy
and like every year, my main observation is that programmers could stand to learn a thing or ten from knitters re: documentation. a good pattern is a beauty of clarity, technicality (with a helpful appendix for the noobs), but also further guidance and observations rather than just "I auto-generated this documentation, good luck"

So, when you block an instance as a mastodon administrator, on account of that instance spewing spam like mad and also none of your users following anybody there, this will NOT resolve any of the >100 reports your users have openend against that instance, despite the reports now being useless.
And of course, Mastodon still has no bulk editing of reports, so you die the death of a thousand ~~papercuts~~ report-clicks … or you just add report-resolving to your management script:

When I plug in the second display after booting up, sometimes my it'll properly choose a second background image (I have a random rotation going on). But some other times, it'll just extend the outermost pixel for the entire second screen. Today, this turned out really well. The second display was even prettier than the first one!

Finally got around to fixing my custom Mastodon stylesheet after the big update.
It's now 185 lines long and there are still things that I want to get around to (but mostly in the admin UI, which – I'm suffering anyway if I'm in there, might as well leave it ugly).
It's not even about anything big, but the dark purple direction of stock Mastodon is really uncomfortable to look at for me.
(Though I am proud of the CW rendering as "▸ Subject:", see rightmost column).

Thanks! This'll definitely end up as some kind of blog post, I'm just waiting for Carlton to publish his first, both to learn something and to write something that complements his.
I do like a cookbook kind of approach – I most often find myself wondering "wait, how do I add a class/attribute to this form field again? something with the widget? what if it's an implicit modelform field?", and either search online or look at other code …

"short" braindump of the frustrations I had with the form rendering stuff
https://gist.github.com/rixx/70fbc8197ed445d9b16652fc42ac269f
(nearly-none of this is about new Django features, fwiw)
It probably boils down to "I'm bad at reading the docs and the code exists and things happen in BoundField oh god", but if we're a bit more charitable, then there are some possibly hard to follow bits in both the docs and the code.

I managed to rip out (finally, FINALLY) django-bootstrap4 in ~a day (assuming 10h work days: https://github.com/pretalx/pretalx/pull/1846), so it's not terrible, but there are a bunch of conveniences that I feel a framework should provide – and the real trouble is that they are hard / impossible to add.
(And sure, I could fix some of the things I want to fix by just overriding the default Django widget templates, but eww.)

My list of grumps is steadily growing, and I'd say maybe half of it is documentation? But parts of it are definitely structural. If I was less used to digging around in library source code / less experienced, I think I'd have quit in frustration hours ago – like I said, it's not due to field groups being around (that's actually definitely good), it's more that … once you try to seriously use them, everything else is janky and in your (well, my) way.

2024-10-09 14:31:37 UTC

The field group template isn't really the issue, it's more that it's the cause of me finally rendering my forms rather than relying on meh-ish libraries, and the whole experience does not spark joy. There are so many janky corners, and I spend half my time reading Django code to figure out why and where things happen.

2024-10-09 12:40:05 UTC

Switching from yesterday's grump about HTML forms to today's grump about #Django forms.
And here I thought updating to current Django would make form-rendering fun and games.

Related: Is there something like a caniuse.com newsfeed that tells me when a feature has become supported by all major browsers (or, ideally, supported by major browsers for a month, half a year, a year …)?

2024-08-22 08:21:15 UTC

TIL: relative colours in #CSS. You define an origin colour, and then modify (with the magic r/g/b/alpha variables for rgb) or override the values. Supported in all major browsers now (except Firefox for Android): https://caniuse.com/css-relative-colors
Example: Use the primary colour, but make it transparent and reduce how green it is:
rgb(from var(--primary-colour) r calc(g/2) b / calc(alpha * 0.5))
