I'm getting my ducks are in a row. I'm putting my chickadees in a column. The squirrels are stored in SQLite. I'm getting my chipmunks in Redis. I've been getting my crows into Postgres. I'm storing my pigeons in Mongo. There are raccoons in YAML? Who put raccoons in YAML? We've got snakes in an OracleDB? Why do we have either of those? Legacy acquisition? We have cockroaches in... well at least that makes sense. You say they're load-bearing cockroaches? And... is this an FTP server for ants?

I designed the 12-bit rainbow palette for use on https://grid.iamkate.com. It consists of twelve colours chosen with consideration for how we perceive luminance, chroma, and hue. The palette uses a 12-bit colour depth, so each colour requires only four characters when specified as a hexadecimal colour code in a CSS or SVG file.

I know people like to make fun of niche operating systems, but for the five years I was at Microsoft I used Windows (10 then 11) as my daily driver. It’s much less stable than a professional OS, but it does kind-of work. I wouldn’t say it’s ready for the desktop. The UI is inconsistent and changes randomly between releases, a load of common software is basically useable only in a VM, it lags and freezes periodically (unlike an OS designed for interactive use, random drivers run a load of things directly in interrupt handlers, so you get latency spikes that you wouldn’t see in a more mainstream desktop OS) and the update process can hose the system, so it’s mostly of interest to people who like tinkering with their machines than people who actually want to get work done. Oh and a load of random bits of the OS have ads, but that’s what you get from a free ad-supported system instead of one developed by an active open-source community.

I don’t think I’d recommend anyone use it as their daily driver or in a work setting, but it’s not totally unusable. It’s not at the level of maturity than you’d expect from, say, Linux or FreeBSD, especially not for client workloads. If you do have to use it, I recommend that you install FreeBSD in a Hyper-V VM for real work. That’s what I did and it works quite well.

That's how serious fiction ought to be written!

https://ai-2027.com/

There's a story to engage with the reader and convey the basic idea, AND there's a non-fiction part to explore deeper ideas that don't fit in the fictional format.

The non-fiction part provides evidence for the story, explains why things unfold as they do, and presents the thesis in an unambiguous, non-metaphorical way.

Bonus points if the story also has footnotes and references, but AI-2027 is the only piece I've seen that does it.

Show threadbenApr 29
Terminal is relatively straightforward and I think they work well. An editor theme is going to be more complex, of course And it's slightly arbitrary which colour is the "bright" one, since the whole point is that none of them are brighter than the other.

actually that blue on a black background isn’t great, not enough contrast.

@katemorley The bit about allowing constrained variance in luminance is very helpful, but how did you actually *do* it? Was this manual, or did you writing something to divide it up given some constraints?
Show threadKate MorleyApr 28
@a I chose three colours (the yellow, red, and blue) and interpolated between them in the LCH colour space, and then chose 12-bit colours that approximated these ideal intermediate colours
Show threadnaught101Apr 28

@katemorley @a

Oh, I maybe this partly explains why I pecieved the yellow as standing out so much. But if this is the case, why are there only 2 colours between red and yellow, and 5 between yellow and blue? Is that to make up for the fact that yellow is offset from green in the RGB primary space?

Show threadnaught101Apr 28

@katemorley I dunno if it's just me, but the yellow stands out as very different from the colours around it, while the ~5 green-blue colours are very similar. If it's perception-distributed, I would have expected more evenness (or perhaps this is me finding out that I'm slightly colour blind?).

Looks pretty as hell though.

Show threadKate MorleyApr 29

@naught101 I think the main reason for the yellow standing out the most is that it’s where the luminance peaks (because if you lower the luminance of a yellow too much it looks unpleasant against a white background).

It does feel like there are a lot of blue-green colours, but I’ve noticed that this is a property of all colour spaces that are designed to be perceptually uniform. I’d speculate it’s an illusion caused by the fact we have lots of distinct names for colours at the red end of the spectrum and fewer at the blue end, and that affects how we interpret the rainbow, in the same way we see pink as a distinct colour (rather than light red) but light blue as just a kind of blue.

Show threadnaught101Apr 29
@katemorley Doesn't that seem oxymoronic though? Like, if it seems like there's too many, isn't that because we perceive that there's too many => it's not perceptually uniform?
Show threadKate MorleyApr 29
@naught101 Perceptual uniformity means we perceive the same amount of difference between two pairs of colours the same distance apart, but that doesn’t mean we’d give them different names. Using my rainbow palette as an example, I would say that the 2nd, 3rd, and 4th colours do seem as distinct as the 9th, 10th, and 11th, despite the former ranging from red to orange and the latter all being kinds of blue.
Show threadAlexandre MuñizApr 30
@katemorley @naught101 I think there's a real effect here. It's quite possible that everybody designing perceptual color spaces is using the same data set (specifically, this one from the 1940's: https://www.rit.edu/science/munsell-color-science-lab-educational-resources#munsell-renotation-data ) The relevance of this data to people looking at their monitors under LED lights may be imperfect. (People's vision may even have been different then!) There also might well be a common bias in translating the colors in that data to modern color coordinates.

@katemorley yeah right. Huh.

For me, colours around yellow are definitely much more distinct than the ones between blue and green. Like, substantially more distinct. To me the orange-yellow-lime triplet seems to cover as much variation as the next green to the last blue (5 colours).
