If you take photos of your B roll camera, does that mean this is c-roll footage?

I mean people have been using Time Switches since the '50s to turn their home lights on and off so people can't tell they aren't at home so they don't get burgled:

It's just a question of how far you're broadcasting your side channel info 🙃

Posting daily high/lows, daily averages, or weekly/monthly averages is much less revealing. But even delayed historical data shows trends.

Even averages can show things like "we weren't home that day much" or "we were clearly on vacation for these days".

It's a bummer, but imo: keep it private.

Yeah, honestly, probably don't. Up to you to decide your threat model/risk tolerance, but if you wouldn't post "hey these are all the times I/my family is home" on the internet, I wouldn't post a livestream of sensor data like that.

It's all sidechannel information leaking.

fwiw: be careful with making data from sensors like this in your home public. They (particularly temperature, co2, and humidity) are *extremely* good indirect indicators of facts like "when you are home", when you are in a room, etc.

The ABSOLUTE numbers are whatever, trends are VERY revealing.

We're excited to announce a new initiative to support the Rust Project, our Rust Maintainers Fund!

We are setting out to employ 6 full-time maintainers and 6 interns in 2026 to make sure #rustlang is well maintained and bugs and contributions get the attention they need.

I'm excited to share what I've been working on with @erikjee.bsky.social: RustNL's #rustlang Maintainers Fund!

Many people and companies contributing to Rust, but there are fewer and fewer paid positions for general maintenance (reviews,cleanups,etc). We need to fix that.

Ooh, that's true, I do think they do mention errata inline, they definitely deserve credit for that!

James Munns @jamesmunns.com · 1d

like, if you FIND an errata, you should ALSO update your reference manual/datasheet with a big "INOP" sticker, or at least a warning like "THERE ARE SIGNIFICANT ISSUES WITH THIS".

I don't get how they keep shipping known-wrong reference manuals/datasheets, that get other updates.

James Munns @jamesmunns.com · 1d

I have stones to throw at all the major vendors, honestly, it's not specifically NXP and STMicro. Even Nordic, who is usually really great, doesn't put warnings in their main datasheet for things like "hey actually this whole functionality doesn't work" (like XIP via QSPI on the nrf52 family)

1 6

James Munns @jamesmunns.com · 1d

at least shout out to NXP for putting that note IN the same document (where they show you in like 4 other places how to use it), unlike STMicro that just has a totally separate errata doc that says "oh lol that doesn't work at all", and they never update the datasheet at all.

Embedded development is great because you'll have a datasheet that has multiple diagrams and sections about the wonderful PLLs, and how you can use them to flexibly divide your clock sources, wow, they are so great, here's how to use them, and then have one little "Note" that says "don't use this".

A screenshot of a datasheet describing a PLL clock divider, but the datasheet also has a note that says:

this clock divider must be set to divide by 1 (DIV = 0). All of the places that main_pll_clk goes have additional downstream dividers (SYSCPUAHBCLKDIV and DSPCPUCLKDIV for example) that can lower the rate locally if desired.

Do you need to explicitly rebuild `core` (and maybe alloc) with your sanitizer settings as well? e.g. `build-std test,core,alloc`?

I can't remember if just specifying `test` also rebuilds all deps.

Having the hint recommend something you're already doing definitely seems wrong tho.

It's from the late 70s, so for some things, there's a world where you could feasibly have used discrete logic (instead of CPUs) to display things, and being able to send BCD means a lot less transistors/logic!

2

James Munns @jamesmunns.com · 1d

A thing to remember is that some avionics (and their standards) are OLD. In some cases, it was just much easier to send BCD to allow for simpler displays and such.

Ben Eater doing an overview of Arinc429 is definitely a surprise. A429 is one of those things that was a huge deal when I worked in avionics, but used basically nowhere else.

It's a fun little 32-bit-word differential serial protocol used in aircraft electronics :D

it's true! though being able to commit your "core work hours" rather than "spare free/personal time" to work on project definitely helps to not *cause* the burnout, IMO.

I find money is fairly motivating as well, to be honest.

Should out to bahn.expert, literally the best train status website for Germany. Simple website with literally anything you could contextually want to know (all the stops, time at stops, platforms of stops, layout of trains, even *datasheets* for the train configurations of routes). Loads fast.
