When I was getting my BMath people would ask “oh, what will you do with that, teach?” and I’m jealous of people taking math now who can come back with “yeah that or pope”.

It just dynamically reads the date, touches the file in case it doesn't exist, and opens it up. It also opens the directory as the workspace so that I can see past notes in the sidebar.

The encoding works by mapping ASCII characters to Unicode codepoints. By subtracting 917776 (space), it's really getting the ASCII offset from the space character.
E.g. the first character 'f' is 917846. Minus 917776 is 70. ASCII character 70 is... 'F'!

Then, it observes that there are multiple instances of 917776, so subtracts that from everything.
The result effectively decodes the message enough to interpret it (FUNINTHESUN vs. "fun in the sun"). That's not supposed to work, but it does!

It immediately detects some unusual tokens, but can't process them directly. It starts by creating a REPL using a tool I gave it (shameless plug: forevervm.com), and prints the ordinal value of the characters.
I've annotated the output it actually saw with the hidden message, "fun in the sun"

TIL Berkshire Hathaway is a trillion dollar Fortune 5 company because Buffet bought it for revenge in 1965.

![In 1962, Warren Buffett began buying Berkshire Hathaway stock for his investment fund, Buffett Partnership Ltd., at $7.50 per share, anticipating that as the company liquidated textile mills there would come a tender offer when he could sell the shares at a profit. A year later, Buffett's fund owned 7% of the company.[17] In 1964, Buffett offered to sell his shares back to the company for $11.50 each.[17] Seabury Stanton, the manager of Berkshire Hathaway, told Buffett orally that he had a deal.[17] A few weeks later, Warren Buffett received the tender offer in writing, but the tender offer was for only $11.375 per share. Buffett later admitted that this lower, undercutting offer made him angry.[18] Instead of selling at the slightly lower price, Buffett bought more of the stock at an even higher price to take control of the company and fire Stanton; Stanton and his son resigned in 1965.[19] However, this left Buffett's fund with a major interest in a declining textile business.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:2wwie4puaidgfvivtkpdgyzt/bafkreihgxeg2xwwa5kqtvdl573xwibnkr2dt7hchfaqgwf43g54x7gpprq@jpeg)

Someone asked me about the difference between UTF-8 and Unicode, here's my explanation in case others find it helpful.

After my post on smuggling arbitrary messages through unicode, some people asked me if AI could decode it. Gemini Flash is pretty fast at it! Have had good luck with Claude too. So far no dice with OpenAI models.

AI is rapidly approaching the level of a junior developer: it can now stubbornly introduce its own favorite language to the codebase without being asked to.

Here's the matching algorithm, if anyone is curious. add_cons comes from russcip, and adds a constraint to the model.
Essentially:
x[i][i] = 0
x[i][j] + x[j][i] <= 1
sum(x[i][..]) <= max_cards[i]
sum(x[i][..]) = sum(x[..][i])
Where x[i][j] = 1 iff participant i sends a card to participant j
Essentially:
x[i][i] = 0
x[i][j] + x[j][i] <= 1
sum(x[i][..]) <= max_cards[i]
sum(x[i][..]) = sum(x[..][i])
Where x[i][j] = 1 iff participant i sends a card to participant j
