  • Back in the day, I set up a little cluster to run compute jobs. Configured some spare boxes to netboot off the head-node, figured out PBS (dunno what the trendy scheduler is these days), etc. Worked well enough for my use case - a bunch of individually light simulations with a wide array of starting conditions - and I didn’t even have to have HDs for every system.

    These days, with some smart switches, you could probably work up a system to power nodes on/off based on the scheduler demand.


  • Yup. Just going by the indexes, the stock market is down all the way to last summer. It’s been a precipitous and steady drop, but if you’re a true believer, it would be easy to say it’s just giving up a little bit of Trump bubble, hope it’s almost over, and relax. After all, they’ve still got their job or most of the stock market gains collected over the last 20 years, so their immediate personal conditions look great.

    Apparently, one of the things that becomes really difficult as IQ drops even a little bit below 100 is hypothetical-conditionals. Like, “How would you feel if you hadn’t eaten breakfast?” becomes, “But I did eat breakfast, and I feel fine.” So, looking at the economic disruption Trump’s causing, imagining that it could continue or get worse, and what that might mean for their personal situation can be a real, does-not-compute struggle.




  • You can configure HA to use an external database, so you could (presumably) config two instances to use the same DB. Not sure how much conflict that would cause for entities that are only attached to one of those instances, but it seems like both should have the same access to state data and history. Could probably even set one instance up with read-only DB access to limit data conflicts, although I imagine HA will complain about that.

    Even with an external database, HA still uses its internal DB for some things, so I don’t think you’d ever get identically mirrored instances.


  • Remember the Arab Spring? Massive protests in multiple North African countries, mostly peaceful regime changes. Those protests were hundreds of thousands of people - less than 1% of most country populations. Most of those nations were still going about their daily business like normal. Complaining about the awful government. Complaining about the disruption of the protests.

    It’s really had to get people out of their daily routines.

    In the US, there’s the extra issue that a significant part of the population are actually happy with recent events because they think it’s going to work out well for them, personally. Some of them think that the chaos is exactly the overthrow of 4 decades of terrible government they’ve been hoping for, and they don’t care what comes after.

    If you’re already running Pihole, I’d look at other things to do with the Pi.

    https://www.adafruit.com/ has a bunch of sensors you can plug into the Pi, python libraries to make them work, and pretty good documentation/examples to get started. If you know a little python, it’s pretty easy to set up a simple web server just to poll those sensors and report their current values. Only slightly more complicated to set up cron jobs to log data to a database and a web page to make graphs.

    It’s pretty straightforward to put https://www.home-assistant.io/ in a docker on a Pi. If you have your own local sensors, it will keep track of them, but it can also track data from external sources, like weather & air quality. There a bunch of inexpensive smart plugs ($20-ish) that will let you turn stuff on/off on a schedule or in response to sensor data.

    IMO, Pi isn’t great for transport-intensive services like radarr or jellyfin, but, with a Usb HD/SSD might be an option.


  • He wasn’t saying to vote third party. He was saying progressive people need to get out and get in the face of office holders, threaten them with personal violence if necessary, for going along with fascist bullshit and trampling on the rights of the helpless.

    He was saying that voting is bullshit. That phone calls & letters to representatives are a little, and getting out on the street matters. Especially if your representative is the other party.




  • Since this article is specifically about pm 2.5, I’m going to chime in and say I have a gas range with no extractor, and the only time my pm2.5 sensor picks anything up is when frying generates smoke and oil aerosols. That’s more a function of cooking temperature than fuel, and my induction hotplate will generate just as much.

    CO2? Definitely more with gas. Trace chemicals? Probably more with gas, but all the studies I’ve seen are just about running the cooktop, with no food, in a sealed room. Run the extraction hood or open a window when you cook - it’s not just heat source.


  • I’ve got one, just a 120V, home-use thing, but it gets far hotter, faster than on my stove. Tends to have a cool spot in the very center, maybe 3" diameter, unless you circulate the wok, and you can’t flame food by tossing it in the fire (which you can’t really do on a residential stove, either). It’s a decent approximation of a wok jet for home cooks.
