    I’m in the “be prepared” group where we usually have a couple weeks of food and water around. We also have two forms of heat for when the power goes out.

    Will we survive WW3 on this? No, but it has been very helpful after big winter storms that took out the city power.

    Having some supplies to use in the short term is good for everyone. Being ready to go out to help neighbors and get the community back on its feet is how we get through to the next good times.




  • Your perspective might be why I enjoy microcontroller work. I love getting to know everything about the system, reading hardware documentation, and getting the low level parts to work in a highly deterministic way.

    I use ATTiny85 cores when a ESP32 costs almost the same, but the 85 only has 256 bytes of SRAM and five I/O pins so I can track it all and ensure it will do exactly what I want.

    I still use wired headphones and earbuds. On the phone it’s got a USBC connector, so I had to find a compact adapter. Fortunately USBC is a tough connector so they’re holding up well enough.

    The earbuds themselves are very cheap. They normally only last a few years (3-5 or so). I snagged a couple little zip up pods that hold earbuds from a job fair years ago. As long as I do a quick coil up, it’s easy enough to pack them away and get them out without tangling. They also don’t get hurt living in my satchel.

    I’ve considered moving to something wireless, but I have enough battery driven devices to babysit already.






  • Yeah, those durn data size fields. At first you’re like “why would you do this? It’s specified in the spec, right?” Then you start consuming the data stream and go “oh, yeah need this”.

    I was doing some driver work for a real time location tracking board. The serial stream protocol was very well documented and designed. Plenty of byte length count fields, though.


  • This approach is so much nicer than the threading/queuing approaches we used to have. One async showed up, a ton of the work go pulled out of protocol handing and distributed subsystem sync efforts.

    Long lived the multi threaded C++ server buffer! Today, async beging to rule the roost.
