A big advantage of using LLM chatbots I have not seen mentioned anywhere else: you develop an “AI-dar”: you can detect when someone is using LLMs to talk to you.

nondeterministic, nonreproducible, but oh so enjoyable, and sometimes the end result is better than expected 🤗

A tragedy in two acts:
I just cooked the best broccoli 🥦 of my life.
It had all the good stuff: guanciale, 🧄, eggs, parmesan, anchovy sauce, MSG…
It was SO GOOD even my 6 year old loved it! That’s HUGE.
But it was all by eye — I have NO idea what proportions I used so I can never recreate it 😭😭😭

This is overt racism. Full stop. There’s no ‘misinterpretation’ and no excuse. This is who he is, who he’s always been, and why he should never be anywhere near power again. And there’s a reason the tapes from The Apprentice have never been released.

This is very popular, yet WILDLY poor advice: “Be constructive, don’t complain about problems if you don’t have a solution”
If you hear someone say this, please consider slapping them with a large trout.
Being aware of problems is *incredibly valuable*, whether you have solutions or not!

And while it’s capitalists *currently* running AI, AI can democratize so many creative fields, bringing resources to individuals that were previously reserved to capitalists with the budget to hire entire teams.
E.g. what will minority entrepreneurs create if VC gatekeeping is no longer a factor?

I haven’t read the paper, but I have no doubt AI assistance worsens coding skills — just like 3GL languages worsened assembly skills.
But software engineering is not about coding, it’s about solving problems with software. Code has just been the means to this for so long we cannot disentangle them.

It is clear to me that LLMs are the new generation of programming language, the biggest paradigm shift in SWE since assembly → 3GLs.
The parallels and differences are fascinating.
Take interpreted vs compiled. Previously a property of the *language*, now a property of the *program*.

Trying to find KTV karaoke near Cupertino and I’m appalled at the options.
Apparently it's either traditional software with terrible UX or selecting songs from YouTube?!
WTF? This is a solved problem, there are services for this (e.g. Karafun), you’d expect Silicon Valley to be doing better.

We'll be getting multiple outlines in #CSS!!
Multiple outlines means no more hacking our way around accessible and creative outline styles with box-shadows that aren't rendered in forced-colors mode! 🙌
Finally!! This is such great news!! 🎉🥳

🎉 Live from the CSS WG F2F: We just agreed to support multiple borders and outlines per element, comma-separated!
But we can’t decide on the order: inside out or outside in?
What feels more natural to you, A or B?
(it needs to be the same across borders and outlines or different box-sizing values)

Alex Pretti "used to tell people off when they made sexist comments to female physicians. He bought me coffee when I had a really bad day as an intern...I laughed alongside him daily. He made a point to teach medical residents without judgement, but with a smile on his face and a joke."

🎉 Very happy I got two of my proposals to Stage 1 at the @tc39.es plenary this week!
Both are around improving the DX of common accessor use cases:

Parents said the food was contaminated with mold and worms & that children were so under so much stress that they were hitting their own faces & wetting themselves.

Analysis by The Marshall Project of ICE data obtained by the Deportation Data Project found that the Trump administration’s revival of family detention has swept thousands of children into ICE custody. At least 3,800 children under 18, including 20 infants, have been booked since Trump took office.
