Not necessarily for sound, on industrial fans and drives, we can program in skip frequencies to avoid any resonance issues in the system. I’ve never done it for noise reduction. But I do some tweaks for efficiency and power consumption reduction. There’s some wild industrial design stuff out there, and in the end, it’s because it provides something the customer wants. I won’t go into specifics, but you can design the same components the same for multiple manufacturers and do some slightly different things in its construction to give the vibe the OEM wants, or to fix some inherent characteristics in the manufacturers platform. It’s REALLY cool when you think about it. Sorry to be so vague, but I have to be.

Admitted, I haven’t read all the comments. I bought a refurbished M2 Mini to use as a cheap media server last week, and so I can use AirMessage with apple users in my life. The M2 Mini is a step down in every way from my ancient mid 2012 MacBook Pro except heat and efficiency. RAM, gotta pay extra for it. Disk space, gotta pay out the ass for it too, and you can’t even get a Mini with the amount of apace I put in my mid 2012 MBP. (4TB)I want to like it, but it’s SO LIMITING without paying out the ass and getting nickel and dimed for everything. I love macOS, especially compared to the disaster that is windows 10 and 11, but it’s ridiculous and so anti consumer nowadays! Which to be fair, Steve Jobs’ ultimate goal with all their products was to make it this way. Want to backup an iPad and iPhone? Good luck. You run out of space almost immediately with the 256GB of storage. Want to use an external disk for those backups? Use symbolic links and terminal, but you’ll have to manually move them to the Mac if you ever need to restore. I have a 6tb external disk attached to it now, but I’m afraid I’m still gonna be hamstrung somehow. All my photos, time machine backups, and media are on the external for obvious reasons. I was also going to pick up a MacBook Air 15" m3 (with upgrades) from Apple, but I’m really rethinking it right now, macOS or not.

So this interests me. I live in a home built in 1920. I have a modern ish furnace installed in 2012. I used 143CCFC of natural gas in January due to the severe cold, for a bill of $226.56. I used Copilot to tell me how to calculate this, so if it is wrong, please let me know. 1 CCFC is 2.832 cubic meters. So I used 404.976 cubic meters of gas. 1 cubic meter of gas is 11 kWh roughly. So I used 4454.726 kWh worth of gas last month. My electric rate from the bastards at Alabama Power/Southern Company is $0.114207 per kWh. So to use electricity, my bill would be $508.76 instead. A swag at furnace efficiency means roughly 80% of my gas went to heating my house. So even reducing that kWh by 20% doesn’t put me ahead. 3565.368 kWh at $0.114207 is still $407.19. Am I missing something? Did Copilot mislead me? Because the savings aren’t there from this math. How do I factor heat pump efficiency in here?

As others have said, Inductive Automation 's Ignition is a fine SCADA platform that runs on Linux. I used it for years until my employer decided we should get rid of Ignition and use OSISoft Pi for data visualization. It’s a ridiculous idea, as they are different products with different use cases, but I lost that argument and have been told to drop it. Still salty, all those development hours and useful tools gone.

I have been recovering from my 4th COVID infection. I’ve told people, it’s not Pokemon, I’ve NOT gotta catch em all. Seems bad luck, my immune system, or shitty people I work around will continue to give it to me. 🫤

Yes they are. As I am at home with COVID for the 4th time. I interviewed a guy in a small room a week ago Friday, and he coughed all through the interview. I was masked. He wasn’t. Two of us caught it. And I found out today they hired the clown. There are strong desires to cuss him out on his first day. Fuck that guy.
