I'd be very scared of IPA in an ultrasonic cleaner. Sounds like a recipe for a fire. Or is your machine perhaps designed for safe IPA cleaning?

It sounds like you have a strong inner monologue. Some people do, some don't. I don't subvocalize (no inner voice when reading). Words aren't involved when I think about stuff. I don't have an inner "voice" at

Huddles in Slack don't work on Firefox on Linux: https://github.com/aws/amazon-chime-sdk-js/issues/2044 . Works fine in Chrome. This is the only reason I keep the Slack "desktop app" around.

Nordic is one of the largest contributors to Zephyr though. I get the feeling that they are pushing hard to make it the de-facto RTOS for embedded stuff. I feel like the whole Zephyr ecosystem is geared towards reducing "time to blinky

Funnily enough, we still don’t fully understand the mechanism by which static electricity is built up when rubbing things together. Professor Merrifield covers this in a very approachable way here: https://youtu.be/0UZb07imN

Not OP, but I’ve dabbled in nRF91 recently and found that once your application starts doing anything interesting (MCUboot, OTA, softSIM, etc.) the code size explodes. It is particularly difficult to keep TFM down to a manageable size. 1 MB

Related to your second point: "FCC seek comments on NextNav petition for rulemaking on lower 900MHz ISM band" ( https://news.ycombinator.com/item?id=41226802 ). No, we are not about to lose the band, FCC is still de

I develop products for the 915 MHz band and became very anxious that I missed FCC's decision (none has been made yet). I agree with GP.

I doubt that key rotation is a significant contributor to energy use. Energy spent doing RF (transmitting) plus energy spent sleeping will account for over 90 % of the energy use. Source: I'm in a similar industry

How are they able to achieve sub-100 meter accuracy? I might be missing something, but In my experience, collecting the cellular parameters is the easy part. The challenge is knowing where the cells actually are. You can ask Google's g

First time seeing the retcons for MOSI/MISO: main out/subordinate in instead of master out/slave in. I'll use that so I can still refer to the pins as MOSI/MISO. The COPI/CIPO alternative (controller out/p

Fun project! Did you look into NTN (Non-Terrestrial Networks) capable modules as an alternative to Iridium? I haven't played with NTN myself, but it seems modules such as SIM7070G-HP-S support LTE-M/NB-IoT as well as NTN networks,

That's a tenth. I agree with GP, "ten times less" is ambiguous.

~/.ssh/config is perfectly fine for that.

Yes, that doesn't help unfortunately. There is a github issue with a long discussion, and none of the tips have seemed to help. https://github.com/microsoft/vscode/issues/65142

I found it witty and somewhat educational, but man is it long . I read it on the kindle and when I thought that I must be getting close to the end, I had only read 30% of it. It takes some determination to get through.

Who are we to decide? Many television tapes were wiped or lost last century because people didn't think them important, including a big chunk of early Doctor Who and a lot of the Apollo moon landing coverage.
