  • It’s been a while since I looked at EVs, but my (US) experience at the time was that Tesla was one of very few companies offering sedan-shaped EVs. The US market was full of crossovers & SUVs (like Rivian), and that form factor seems antagonistic to many of the things that make high performance, long range EVs: terrible aerodynamics, high body weight, poor visibility… They’re big enough to fill will batteries to compensate for the poor efficiency, but that just raises costs.





  • In an election where the margin of victory is 1%, it only takes 1-in-50 racists to throw the election.

    Sure, Kamala wasn’t hugely popular with internet Democrats. Sure, running as a centrist annoyed all the people looking for change. The whole Israel thing. Voters overlooked all of that with Biden in 2020, when he wasn’t hugely popular with internet Democrats & came with a 50 year legacy of supporting some atrocious policies.



  • Not exactly the same, but I have an air quality sensor I use to turn the HVAC fan mode on/off to filter. Also a CO2 sensor. Both wired to the RPi I run homeassistant on. The HVAC is controlled via T6 pro Z-wave now, but I started out with a Zooz Zen15 switch to just turn the whole thing on/off.

    The CO2 sensor has been pretty stable for 4(?) years - it has an internal recalibration routine that resets its baseline based on the past week’s data. My readings range from 400-ish with the windows open & fans to 1200+ cooking with gas in the sealed house. Averages around 800 with the AC or 500 with the furnace (which exhausts combustion gasses). The aq sensor has been replaced once after 3-4(?) years. It reads exactly what purpleair says is outside with the windows open, drops to 0-2 µg/m3 with the filters running, spikes to 300+ cooking.








  • I switched from an I3-530, nominal TDP 73W, to an N-100, nominal TDP 7W, and power from the wall didn’t change at all. Even the i3 ran around 0.1 CPU load, except when transcoding, and I’m left with the impression that most of the power goes into HDDs, RAM, maybe fans, and PS losses. My sense is that the best way to decrease homelab power use is to minimize the number of devices. Start with your seyrver at 60W, add a WAP at 10-15W, maybe a switch at 10-15W… Not because of the CPUs, necessarily, but because every CPU every CPU comes with systems to keep the CPU going, keep the power regulated, etc.
