We haven’t had a Color Wheel Wednesday in a while! Oh happy day! Even though these five color wheels look similar, I used different combinations of pigments to paint them. It demonstrates how some pure pigments are brighter than what you can mix from other pigments, but you can also get very similar results from different pigments. Our perception of color is relative, and you probably wouldn’t notice the difference if they weren’t right next to each other. #color #watercolor #painting #mathart

@ZachWeinersmith @uastronomer here's a variant:
- the world is made of two 3×3 grids, each representing a player's home planet.
- the goal is to build a 3-cell long landing strip on the other player's planet.
- the game starts after each player placed two secret 1-cell military bases on their planet.
- each player in turn picks a position on the other planet where a piece a landing strip will be built unless it's occupied by a military base, in which case this fact is revealed immediately.
- the first player to complete a landing strip on the other planet wins.
This may be become more interesting with larger grids and more bases. Maybe the possibility of moving a base by one square on your own planet instead of a regular turn could be interesting.

@tofugolem idk, my landlords have no difficulties picking fridges that never break. 😂

The Time Traveler (for so it will be convenient to speak of him) was expounding a recondite matter to us. And then the dragons arrived.

Poll result: 29% of the world believes chocolate milk comes from brown cows.

Work in progress: a testing framework for OCaml that supports checking test output against expectations.

It works and we're using it at Semgrep but it needs basic documentation and other straightforward work.

Does chocolate milk come from brown cows?

Wait, what? (screenshot #1)

Do I read this correctly: Artists submit their work for an auction, and if they're selected and the painting sells, they get between 0% and 15% of the selling price.

Oh, they list "benefits" (screenshot #2). Let's see.

> All selected artists will be included in our robust promotional campaigns.

Oh, you'll use my art in an ad campaign for free. Awesome. I'm gonna be famous.

> Artists will receive bidder information from their sold artwork after the Auction.

Do we get their cell number and the name of the school attended by their children? I can't wait to stalk them.

> All artist applicants will have their work seen by local art-world luminaries who jury the work for inclusion consideration.

Sweet, a jury of local randos will get to see my painting.

> Your contribution as an Auction Artist directly supports ArtSpan’s programs, and has a positive impact on our local art community.

Sounds like an ineffective way for artists to give their money to other artists.

You know what, I'll skip this and focus on making art.

@freeschool I have many philosophical things to say, some of which requiring fewer prerequisites than others. I'm looking into compiling them into writings before I die. The main topics revolve around the nature of world models and minds. I'll get back to you if I find something that fits the one-minute audio format. What's the target audience? (any technical knowledge I can assume?)

@dpiponi any input that was acquired by built-in hardware or software is a feature.
1. There's no harm in providing pre-computed features along with the original input.
2. Without giving the machine the ability to extend its sources of input i.e. the ability for itself to build a tool that allows it e.g. to look into the eyes of the opposing chess player or to browse the Web freely, it's still being fed features.
Hope you find this useful.

@freeschool I'm barely posting anything here. On Twitter, I used to post technical info mostly about the language. That was until about 2016. It was an effective way to get followers but not to have interesting conversations about anything. I'm more true to myself now. I don't want to post one-way messages in the style of influencers. Every message is a message in a bottle in the sense that I desperately want reactions but I'm not getting them.

@randahl I don't know. I'm a bit worried about all the outsiders with strong opinions who think they're not outsiders.

@freeschool thanks for the feedback. It seems to be working as intended. People who can't stand my approximate language end up not following me and I don't have to deal with them later. The other way would be that I have to over-explain everything I say. I'm not interested in that because it wastes time for me and for my intended audience.

I was reminded that most people outside the software industry have no idea that today, the world runs on top of free and open-source software. They're convinced that "nothing is free" "because capitalism". It's like some of those immigrants from communist countries who believe that selfishness is a requirement of capitalism...

Note that I'm not particularly advocating for the exploitation of free software authors, only stating facts.

A thing I always wondered was why the first RPL calculator, the HP 28C, was so underpowered for its operating system--just 2K of RAM, which would quickly run out if you were trying to use its powerful software to do anything significant.

Apparently (based on a comment I read somewhere) it's because the hardware was just a repurposing of the HP 18C Business Consultant, which had the same physical clamshell design as the 28 but was a business/finance calculator. The 18C's software was written in RPL, but RPL was not exposed to the user, it lacked the 28C's complicated algebra/calculus/scientific functions, and it didn't need more than 2K to support its capabilities.

HP felt that this radical overhaul of their scientific line was a big risk, and the easiest way to mitigate that was just to ship the first model on the 18C's hardware without spending any money on upgrading it. Once it was successful enough, they came out with the 28S with far more RAM, and eventually the 48SX which was more or less what the designers of RPL had really wanted to ship in the first place.

Love de Lempicka's work.

"For a trailblazing female artist and Art Deco star, beloved by celebrity collectors from Madonna to Barbra Streisand, Tamara de Lempicka has surprisingly not yet received a major retrospective in the United States. That is, until now."
