I love education & technology. I helped build @3Blue1Brown’s website and made (I am @joshpullen27 on Threads)

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.

@adamwathan I like that [] syntax indicates stepping outside the regular system. How about px-[47]?

[Josh Pullen @PullJosh]

@simonw Maybe this is also a strength of LLMs: Taking general knowledge and just tuning it slightly to a particular context.

[Josh Pullen @PullJosh]

@simonw Side-by-side comparison of its response for you and for me. Almost identical. It adapts the details to each of us, but the response content and format is eerily similar.

A vague relatable statement, slightly tailored, comes across as surprisingly convincing.

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 Pullen @PullJosh]

@tylerangert You're looking for `Object.groupby(array, callback)`

[Josh Pullen @PullJosh]

Chaos engineering sounds so fun

[Patrick Collison @patrickc]

@karpathy I've always thought that we should run scheduled internet outages.

[Josh Pullen @PullJosh]

@adamwathan I... really thought you had to use position: relative for this

@bates64a This didn't fit in a Tweet: https://t.co/v5htmq8xD2

[Josh Pullen @PullJosh]

@adamwathan An employee only has one job (generally), but an employer has many employees. I feel like that might explain some of the imbalance in the dynamic.

[Josh Pullen @PullJosh]

@ddmeyer Watching the "help me solve this equation" portion of the announcement was quite a ride. It's cool tech. But "help me solve a math problem" is very much not the correct demo.

@kolibril13 @tldraw @matplotlib This is neat!

@realbashlk I have absolutely no idea why it would associate this with my website specifically. The only thing I can think of is that one time I wrote a semi-popular blog post about iframes. And the source code for my website is on Github. But that's it.

[Josh Pullen @PullJosh]

@realbashlk Woah that is fascinating 🤯

[Prabashwara Seneviratne @realbashlk]

Hi @PullJosh
I was writing some code to remove iframes from my RSS feed and Github copilot suggested some code which is from one of your sites I think. 😄

[Josh Pullen @PullJosh]

Pretty sure the twitter algorithm suppresses posts containing the name of The Other Platform

[Josh Pullen @PullJosh]

I haven't figured out why, but if you plot z = y * sin(x), it looks all wavy until you make your graph polar, at which point it becomes a perfectly flat disk.
