What is unclear to me is whether a special phone app is required or not. One of the web pages indicates that it piggybacks onto the infrastructure for airtags/android tags (not clear which). Certainly, if I was building these, that is what I would do as getting a custom app in enough phones would be extremely difficult.

Having said that, the claim is also that these tags report temperature as well — but there is a field (personalized name) that could be used to transport that information. In any case, it is an impressively small tracker!

I was hoping to find a 'blink the LED' example for the ESP32. Then I'd like to see 'Blink a LED at 1Hz and another LED at 1.234Hz' (or any pair of frequencies where one does not divide the other).

When I was a consultant, the saying was:

A consultant is someone who borrows your watch, tells you the time, and keeps the watch.

For me, it is "how many passkeys can I have for the same site?", and "how do I revoke them?"

Worse, I'm still using LastPass -- but migrating over to Chrome password storage as it syncs between phone and laptop. LastPass doesn't give you the option to not use it for passkeys. It might be the thing that causes me to finish the migration away from it.

This is amazing -- but there is something wrong with (maybe) the WebGL or color rendering. If you go to https://pskreporter.info/pskmap then the ocean should be blue (and it is blue in a native firefox). However it is a shocking shade of pink in the wasmified version.

Still, it is amazing that it works at all!

What is the data supposed to represent? Given an IP, I get back some indication of location. Is this

(a) The location of the user who uses this IP at the moment?

(b) The location of the device that is assigned this global IP?

(c) The location of the switch/router at the ISP that is directly connected to the device with the IP?

(d) The headquarters location of the organization that registered the IP block.

(e) Some other location we can't describe.

(f) One of the other answers, but at some time in the past.

These are not all the same location, and not necessarily the same country. Think about people using phones, on airplanes, at sea, in the desert using starlink, corporations using internal networks to get to an ISP POP in another country.

Many companies have internal directories which can be downloaded and (say) committed into git on a daily basis. This could be automated in a cron job. This then gives an immediate view into what is going on.

I believe that the Slack API (if your company uses Slack) can be persuaded to give you the list of deactivated accounts. Then you just check this into git (on a daily basis), and you are done.

And, of course, in this AI Agentic world, you can probably ask your HR bot about the recent layoffs and get the information even more easily!

I picked Vitamin D as it was an option on the main page. The cheapest offered was $1.1/mg.

Costco (https://www.costco.com/p/-/kirkland-signature-extra-strength...) sells Vitamin D at less than half that price. On Amazon, the two pack of those is even cheaper.

Just an observation.

I suspect that my Tesla adjusts its location based on dead reckoning after losing GPS lock except that it assumes that I'm driving forwards. I.e. If I reverse out of my garage, then the map ends up in the wrong place and now I'm driving parallel to the road!

I'm not convinced that the units conversion is right. The example of 2 Cups of greek yoghurt being 391.32 g. 1 US cup is 240 ml (or 236.5 ml depending on which type of cup you are using). The density of greek yoghurt is somewhere between 0.96 g/ml and 1.04 g/ml (depending on which website you trust the most). This leads me to calculate that 2 cups greek yoghurt weighs between 454 g and 499 g). The 391 g value is way off.

The article seems to think that a word is untranslateable if there is no single word in the target language. If I'm not misreading the article, then this is completely obvious -- just consider the number of words in English and the number of words in almost any other language, and you will find that there are more English words than the other language. It is now clear that there exist English words that don't correspond to a single word in the other language.
