2¹³⁶²⁷⁹⁸⁴¹−1, discovered today, is the largest known prime. It's a Mersenne prime (2ᵖ-1), which are easier to find. It took nearly 6 years for the GIMPS software to find it after the previous largest known prime. It was also the first Mersenne prime found using GPUs.

Collaboration tools are one of the things where technologists like myself think we understand the problem-space; We really do not, at all.

It has been a while that I have posted about the calculator here. The more I work on it, the more problems I find to fix

👇 Josh needs a win. I wrote up a way Josh could get a meaningful win with 5-10 minutes investment every day next week. danmeyer.substack.com/p/can-… nitter.gq/PullJosh/status/169620…
I've been student teaching for two weeks. There are 1,000,000 things I could be doing better, but I can't fix everything all at once. What should be my top priorities in the early days, to help me go from drowning to competent? joshuapullen.com/blog/new-te… (cc @ddmeyer)

Prompt injection keeps getting wilder. Unlike text-based methods, you can't tell by looking at one of these images or audio clips that it's malicious. It can be embedded in a website/email attachment and will alter the model's behavior if it processes it. arxiv.org/abs/2307.10490

I wonder if AI is best used to generate interesting math scenarios where the solution is legitimately unknown Instead of asking the computer to generate problems it already knows how to solve, can we let it generate interesting scenarios and ask students to do the heavy lifting?

This is a wave packet calculated with python. It's displayed in a @tldraw canvas and controlled by a @solara_dev slider in Jupyter. I think this bidirectional communication between python and an interactive whiteboard has a lot of potential!

My daughter, who's had a degree in computer science for 25 years, posted this about ChatGPT on Facebook. It's the best description I've seen.

Also (opinion): the development of these simple CRUD apps is just *begging* to be automated away by low-code tools. These kinds of apps have been "solved" thousands of ways now for decades and modern frameworks are just putting their own performance/DX twist on it.

Strong induction is where you climb a staircase by placing one leg on each previous step (you have n legs)
