Board books. Adult reads, let the child turn the pages.

Simple kinetic toys, of the sort where you put a ball in a hole and it pops out somewhere else. Same pleasure as a marble run, without the choking hazard.

Adult mimicry toys, like play kitchen, doctors bag, etc. With the right setup and creative inspiration they can learn to putter about inventing simple tasks and executing them.


Thank you for writing about parenting. Today was a tough day with the kids, and reading your blog after they’ve gone to sleep helped things feel a little better.

I don’t understand the point of this theory. Not having safety controls is bad, but having practices so bad that workers violate N layers of safety protocol in the course of operation is also bad. They’re both problems in need of regulation.

I was trying to focus on one specific pattern without making my post too long. Alert fatigue, normalization of deviance etc. are of course problems that need to be addressed, and having a lot of layers but each with a lot of giant holes in them doesn't make a system safe.

My point was that in any competent organization, incidents should be rare, but if they still happen, they almost by necessity will read like an almost endless series of incompetence/malfeasance/failures, simply because the organization had a lot of controls in place that all had to fail for a report-worthy bad outcome.

Overall incident rates are probably a good way to distinguish between "well-run organization had a really unlucky day" and "so much incompetence that having enough layers couldn't save them" by looking at overall incident rates... and in this case, judging by the reports about how many accidents/incidents this company had, it looks like the latter.

But if you judge solely on a single incident report, you will tend to see companies that don't even bother with safety better than those that generally do but still got hit, and you should be aware of this effect and pay attention to distinguish between "didn't even bother", "had some safety layers but too much incompetence" and "generally does the right thing but things slipped through the cracks this one time".


The failure rate of an individual layer of Swiss cheese should be bounded under most circumstances but not all. So you should probably have more layers when hazards cannot be eliminated.

Ah well, shame about that.

Was genuinely hoping to find there was some interesting research going on, but it’s all just AI stuff.

"Was genuinely hoping to find there was some interesting research going on, but it’s all just this "calculus"" -- everyone, in 1670

Imagine putting ai and google at the same level as calculus.

Yeah it's insane to me to claim that AI (so far: useless, may one day get good) is remotely in the same ballpark as calculus (a proven technique which has led to a ton of useful stuff in the world).

For one it's an analogy - for two the jury's out.

How is a good analogy if calculus is known to be fundamental in our understanding of the world and for ai the jury is out?

Give it 20 years and AI may be the most important thing mankind has ever created.

And it may not be. We need to judge it on what it can do today, not 20 years from now. And today it's pretty useless.

> today it's pretty useless.

This is quite the statement. Even my elderly father finds it incredibly useful. And he doesn't even know how to turn up his iPhone ringer (which BTW it helps him with).


It's been pretty great for me. I don't know Python but was able to use Google Antigravity to make a script that composites meteor trails from hours of video footage. This would've easily taken me 12 hours without AI. It also wrote a grease monkey script that automates a website I use.

I have been reading the same since the 70s.

Sorry if I think your comment is a joke.


Upsell opportunity. Remember the number ordering was originally for “extra value meals” that purported to save via bundling. Over the decades the perception of value was lost, hence the move to à la cart, luring consumers with more variety.

Makes sense, but I still don't understand why the signage behind the registers is so seemingly incompetently designed.

They don’t want you moving through efficiently, they want you to spend more time purchasing more items.

The year is 20X5. Despite the onslaught of artificially intelligent agents capable of understanding and synthesizing new concepts in written language, humans are still capable of basic cognition… for now.

Author deserves an award for coining the verb “incorrecting”.

It’s always amusing to see a topic that’s so esoteric no one can toss off low effort drive by comment on it. Let alone have insightful input on the subject.

I’d believe it’s the mods juicing it by hand, but perhaps there’s an algorithm filtering for subject distance from the core hn oeuvre?


Last.fm used to only update your listening stats on Friday, which turned into a fun event where everyone shared what they heard that week.

Eventually the stats became live updating and a bit of fun was lost.


I'm on a music discord server (for metal), most people share their weekly, monthly, quarterly, and yearly charts made from their last.fm data. Here's what I posted yesterday for my weekly: https://i.imgur.com/6jYS8jG.png
