It’s like a non-calculus based astronomy course. Sometimes you just want to learn about the thing directly without spending two semesters learning the mathematical machinery first.
The content is pretty good but I think they missed the target audience pretty badly with that title and cover.
If I was trying to make that jump from arduino blinking an LED to custom PCB again something like “Applied Circuits: A Practical Guide to to PCBs” with a cover in the style of the circuit diagrams[1] would be an instant buy.

I'm in agreement with you. The cover art and title give the impression of a children's book or a coffee-table book or something "light and fun!". It's not a textbook, but it's much more than a fluffy lightweight children's book. Reading the sample chapter, I think the audience he should have targeted is anyone who liked the monthly magazine "Scientific American" (if you're old enough to remember that). Basically anyone who wouldn't mind being called a hacker, nerd, geek, or science fan. Which is still a huge audience.
I’d argue Kudzu has visibility bias. It grows on sunny roadsides, railway corridors, and disturbed land. Basically all the places where people see it so attribute it to being more pervasive than it is. It's also mostly harmless[2].
Bad code is the inverse. It’s more pervasive than people think it is and builds up precisely in the places that are not disturbed. More like Privet than Kudzu. But that isn’t nearly as catchy.
If you want to dig into the quasi redemption story of why Kudzu isn’t this terrible evil we’ve given it to this was a decent episode of 99%PI at around the 18 minute mark[1].
This description feels like you are describing mold. It is invisible. It smells bad. And can slowly erode everything it grows on. One day you will take a shovel with molded handle and it will just detach.
Don't discount disturbed land. Early successional habitat is even more biodiverse than old growth forests, and high quality early successional habitat is very rare in the south.
Part of getting deals done in China (in the old days) involved drinking.
After enough trial and error, I found I had luck with pre-gaming bioavailable pre-pre-precursors and water about 6 hours before drinking. More so than just water. Or just precursors.
The surprising bit I learned in some papers (in mice) was that glutathione precursors like NAC can actually do more liver damage if taken after drinking than just taking nothing. Timing seems to matter a lot.
That and there’s a bit of a difference between effective hangover prevention and after the fact hangover cure. The latter is kind of like asking how to uncrash a car. IV drips are very effective for symptom relief but the damage is already done.
It does give you the option to change cards when you double tap, before you pay.
But I think the real reason is that people would walk around with card readers and scan peoples watches to collect cash. I can only guess it doesn't happen in Japan for cultural reasons. You could try and do that with purses/wallets too, but since most people are carrying multiple cards, they interfere and largely prevent RFID skimming.
I recall we were seriously talking about using one during the early days of the Deepwater Horizon disaster. For a variety of reasons it wouldn’t have worked in that instance.
I just restored an 1800’s house and we redid the paint in limewash as part of that process. (Effectively zero VOCs but pretty caustic when wet.)
Historically (for interior paint) you would use regular limewash in dry spaces and add casein/milk in high traffic/wet spaces. It works in a bathroom but wouldn’t hold up in a shower (for that you would want to use “tadelakt“ - especially if you’re going for that Aman spa look).
The contemporary solution with modern limewashing is to use “mineral shield” - it uses silicone instead of casein - it makes water droplets bead up but still lets water vapor breath through.
It also doesn’t flatten out the nice velvet texture one gets with limewash paint from the calcite crystals.
That said, it’s extremely obvious if one touches up a patch of wall with limewash. No two batches are the same color unless you’re going pure white and even then…
Seeing the index in action next to an oura I appreciate how much smaller/thinner the index is (or at least how much less it seems to “spread” my fingers apart with of a width of 6.5mm vs 8mm).
It’s effectively a regular ring with a button on it that’s smaller than a typical 1ct engagement ring. The oura by contrast (even the 4) is a chonker compared to “regular” wedding bands. I’ve tried in the past but personally a very thick ring is a non-starter for me. Might just be a personal sensitivity thing. Clearly the oura sells.
From a V1/MVP/founder lens I am sensitive to the value in shipping a product that just works rather than doubling the complexity with a bms, custom charger, wrap around flex pcb, and associated engineering effort to mitigate ignition hazards. Especially when there’s platform risk in seeing if this thing even gets used. There’s no platform risk on the watch side which has comes miles from my first pebble/Alerta that was one day charge and blackberry phone compatible only.
As for the ewaste argument? If the market demands a rechargeable product then that’s the right move. But from a weight perspective? This feels performative. Even pessimistically three-four 5g device that are 0% recyclable will generate less ewaste than a 200g phone with 55% recovery and a 5% recapture rate of obsolete devices thats turn over every 3.5 years. It’s like 10x less and probably in the ballpark of what a hypothetical “rechargeable” index would look like.
