I love education & technology. I helped build @3Blue1Brown’s website and made https://t.co/6wfzTx7e8M. (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]?
English
Starting to wonder if the gaps in our spacing scale — while noble in their goal — are more annoying than they're worth…
Should we just make stuff like `px-47` work in Tailwind CSS v4?

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

Here's a blog post about how that ChatGPT trick where you ask it to provide insights into your personality is _mostly_ snake oil, relying on the same cognitive bias (the Barnum effect) used by horoscopes and personality tests simonwillison.net/2024/Oct/15/ch…
Simon Willison@simonw
There's a meme where you ask ChatGPT "From all of our interactions what is one thing that you can tell me about myself that I may not know about myself" - don't be fooled into thinking there's anything deep going on here, its effectively a horoscope generator

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

@tylerangert You're looking for `Object.groupby(array, callback)`
English
there should be a method like .filter but it's .separate() or something where it filters according to the condition but returns both the filtered and non-filtered elements

Chaos engineering sounds so fun

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

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

Once you understand the CSS `isolation` property, you'll basically never wrestle with `z-index` issues again.
Quick one that will fix 99% of your problems — throw `isolate` on your main layout container, so any portaled elements are guaranteed to be in another stacking context.

@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.
English
I think this makes a lot of sense but it’s interesting how doing the equivalent on the employer side would be considered pure evil — always interviewing new candidates for roles you’ve already filled with good people just in case you find someone better to replace them with.

Why software engineers should interview around even when happy:

@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.

This is @tldraw in a notebook, connected to the new GPT-4o vision API. This video is at original speed, and it shows how @matplotlib plots are generated from scribbles.

@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.

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. 😄

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

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.
