Summer Undergraduate Internship - reposts welcome!

Are you a senior undergrad, interested in Programming Languages? Do you want to visit Canada for a paid 12-week internship?

Proof of P = NP: The Harmonic Collapse Abstract A full and final optimised twin harmonic spiral solution for P=NP in polynomial time, with proofs and scripts.

A little sent by this "proof" of P = NP that incorporates Lean, as if that helped in the least. Maybe it does! But... not much.

A tweet from BBC News (UK) reads: "Monkeys will never type Shakespeare, study finds." Below the tweet is an image of a chimpanzee dressed in a button-up shirt and wearing glasses, sitting at a modern desk and typing on a laptop, mimicking a human office worker. A caption on the image says, "'Infinite monkey theorem' challenged by Australian math..." Underneath the tweet, a community context note clarifies: "Infinite monkey theorem talks about infinite monkeys over infinite time. This study talks about finite amount of monkeys over finite amount of time."

I like how explicit How To Design Programs is about the process that takes place in my head but that I never named.

"IDK all the details right now but this function surely will access the three numbers in the input list. Put those accesses in there surrounded with ..., deal with the rest later"

it is impossible to generate code comments from source code because good comments are definitionally based on things not in the source code (intent, counterfactuals, experiments, etc.)

I already hinted at it a few times. I’m building a new development environment for macOS. The current focus is on Haskell support, but it can also do Agda & Swift. I only just started beta testing with external testers, so there are still rough edges. Interested in giving the beta a spin? Send a DM!

HOMEWORK MACHINE

The Homework Machine, oh the Homework Machine
Most perfect contraption that's ever been seen. 
Just put in your homework, then drop in a dime,
Snap on the switch, and in ten seconds' time,
Your homework comes out, quick and clean as can be.
Here it is β€” "nine plus four?" and the answer is "three."
Three?
Oh me ...
I guess it's not as perfect
As I thought it would be.

The more I learn about atmospheric chemistry, the more terrified and angry I am about satellite companies' blatant lack of consideration for how their actions will harm the atmosphere. I hope this gets a lot of press. Great work by a whole team of scientists, including @astrokiwi.bsky.social! […]

To show the absence of bugs you need a proof that works for all inputs. Failing the proof doesn't necessarily give you insight into WHAT input is wrong, or even if there is a wrong input at all! While a failing test guarantees you know at least one buggy input.

Right, but you're not really asking for reviewers, because it's not just review, it's *the actual hard interesting work of the project*

Right, but you are apparently either unwilling or unable to check the outcome of the experiment, while at the same time saying "This experiment was a success, as long as someone else does the work of verifying it was a success"

But the math holding is the only part that matters. You've asked an AI to build a car, and said "I haven't checked if it runs, but if it runs, look how amazing it is." You've done a pale imitation of the actual task, which is *checking if the math holds*.
