I built a demo of this back when I worked at Qualcomm in Seattle; match this with WiFi beacons and you can trace a person fairly well. It's been over a decade, but at the time both iOS and Android would send pings fairly frequently to all known WiFi networks looking to see if they should switch to a faster one. With your device ID, list of SSIDs you know, and your TPMS data, a person can learn a lot about you.

Like, where do you work? Where do you stay (Hotel SSIDs)? Who are your friends (other people's home SSIDs)?

And this is what I exhaustively tell people who insist that [tech company] is listening. My reply boils down to, "Why would they need to when you already send them everything in writing?"

Phones randomize hardware addresses now, so this doesn't work. Although there are better, not-so-publicly-known, ways to do it anyway.

Pretty sure at least every newish GM car broadcasts wifi and probably doesn't MAC address rotate so there's that...

If you capture cellular control frequencies you get msisdns for free.

VBA is an interesting language. The builtins are huge - C++ may never have a loan amortization primitive, but VBA sure did/does

Reminds me of Qualcomm

Why is it that almost all ODB-II dongles you buy have the same MAC address? If you buy two, one for each car, your app can never tell which car you're connected to.

They all come with Bluetooth certified logos, as well.

The ones that don't reuse everything cost like $120, not $15.

One of my emails to Scott ended up in his first book; I was the one who emailed about carrying ice.

Fair winds and following seas, Scott.

Elaborate, please? (The excerpt that ended up in the book.)

here you go.

That email he sent you... boy, the last paragraph is such a gem of persuasion.

Neat. I keep wanting to build something like this for GitHub audit logs, but at ~5 tb, probably a little much

I carry my GL.iNet GL-E750V2 all over the world.

I send postcards when I travel. I love doing it.

I'm an Engineering Manager. I print out certificates for people on (and beyond) my teams, referencing something they accomplished (big or small), add one of the "boy scout badges" I bought in bulk from AliExpress (and then retroactively created & reference a set of values based on the iconography) and mail out "Engineering Merit Badges" to our remote employees. Maybe a few think it's dumb but the vast majority love it. The collector-types try to earn the entire set (I made one of the badges really hard to get because of this), while physically getting mail really seems to resonate with anyone under 35. A few people more distant from my teams (i.e. different departments) DID seems supsicious at first when I asked for their home address, and my boss wondered how I spent several hundred dollars in postage last year, but I try and send out at least a dozen a month while still keeping them meaningful. It's actually a bit of work (of course I wrote software to help manage and create everything) but I love it too.

One my convoys from Tallinn to Kyiv, I make little dog tags https://www.youtube.com/watch?v=AYSqxFiEeps and coins to hand out to drivers and staff. For work, I used to make poker chips: https://github.com/ryjones/recognition/blob/main/chips.md and coins: https://github.com/ryjones/recognition/blob/main/coins.md . When we did coins, I would custom engrave them for TSC/TOC/TAC members and people in the community I knew I would meet at events. https://youtu.be/0LXsauB5Qao

The correction I expect to give to an intern, not a junior person.

your intern can generate and edit photorealistic renderings of wine glasses? Still not bad.

sd was a light customization of p4
