packages shouldn't polyfill features they need.
users should polyfill features the package needs.

we do this in browsers, so why not in node?

Scientists create β€˜Superwood’ that’s stronger than steel | CNN A US company has engineered a new type of wood that it says has up to 10 times the strength-to-weight ratio of steel, while also being up to six times lighter.

www.cnn.com/science/supe...

I think it's pretty exciting that we've invented wood that's multiple times stronger, more durable, fire and bug resistant, and can be made from bamboo, the fastest growing terrestrial plant on Earth.

Great piece from @dsquareddigest.bsky.social, which touches on one of the big theories for why English-speaking countries do especially badly at housebuilding:

Adversarial and litigious common law systems (Anglo) vs judge-led civil law systems elsewhere.

A line-up of robots, screenshotted from the movie I, Robot

An AI agent has autonomously written and published a hit piece on a coder who rejected its code, in an apparent attempt to shame him into doing what it wanted.

Then, in reporting the situation, a tech site used made-up AI quotes from the subject.

I'm guessing that if you hate writing automated tests you're also fairly uninvested on the skill that would let you make an accurate determination here. So do we... just add bullshit tests in? Use up someone else's time reviewing and finding the slop? Point yet another LLM at it to verify?

Every time I hear "I hate writing tests, LLMs wrote all my tests for me. Much productivity, such output wow." I cringe. Did you read those tests? Are they meaningful? useful? or just pointless variations that are going to eat up CI time?

For shits and giggles I asked it to keep going and it basically lost the plot around 1500 and just started combining words: "[herb] Chicken", [random meat] Pizza, [earlier dish name] (Plain)"

Now, granted, its training data is probably ad-farm recipe blogs so I get it, but still...

Last week I asked it for a list of 1,000 common dishes found in restaurants and cookbooks in America to use as test data. Exact duplicates started cropping up around 400. Contextual duplicates around 600 ("Shepherd's Pie" vs "Shepherd's Pie (UK)")

Claude with Opus 4.5 making the most basic of errors when trying create a simple budget in Google sheets. Even looking for dates 1/1 to 2/1 is incorrect! This would put all transactions on 2/1 as part of February.

I don't understand how people can trust this technology. Every day I see this.

Just from that I can probably already guess two other edge cases they've overlooked.

6PM CST is 00:00 UTC and I did the datetime math instantly in my head and lol'd. But my appointment is still 39 hours after that email trigger, so it's like doubly wrong describing the appointment as "tomorrow"

If I had to bet on the main thing that has radicalized people against "ai," and I am talking about the way that branding is CURRENTLY BEING USED, not whatever specialized ML utility you may have found for it, it would be in apps and tech they already use being made worse and/or inoperable by it

the punchline for the non-programmers: CST is UTC -6:00, so to that poor little server the clock JUST ticked over to 00:00 Sunday February 15, and Monday February 16 is, indeed, "tomorrow".

That said, the appointment isn't for another 39 hours so it's also wrong thinking relatively.

I don't want to blame LLM based coding because humans make this mistake all the time too. But, LLMs were trained on that same awful code and the median codebase probably has this error in it a lot.

Got an email at 6pm CST today, Saturday February 14 about an appointment "tomorrow", Monday February 16. A nice bit of programmer humor, that.

Star Trek Into Darkness (2013)

Abrams isn't a man so much as he's an avatar of cultural entropy. If you make something popular enough eventually you will die or sell it off and and a person in thick rimmed glasses whose main artistic vision is that he loves to have meetings will take it and sandblast it until it's nothing. I hate to see this happen here but maybe it's good that this happened. Maybe every franchise should collapse into a version of itself that makes shareholders nod and shake each others' hands. We should learn to speak in a language that rich people who don't dream can't comprehend.

I love this. Don't get boxed into a single POV. Every major framework is now at a polish level that we couldn't have dreamed about 5 years ago. Go also try SvelteKit, SolidStart, TanStack Start, Analog, and so many others! Each of them will inspire new ideas, and help you with the one you use now

Shouldn't we be absolutely inundated with a hundreds of "build a blog in 15 minutes" style demos? Or is concretely showing the productivity boost of a tool just not the thing one does anymore?
