  • So I had no context for how big that is and why it’s newsworthy

    To put the sheer size of the 8 GW solar farm in perspective, the three largest solar farms in the world by capacity are China’s Ningxia Tenggeli and Golmud Wutumeiren solar farms, with a capacity of 3 MW each, and a 3.5-GW solar farm outside Urumqi, Xinjiang’s capital.

    Tho still didn’t understand the scale until I looked up a stat on nuclear

    Nuclear energy has been powering the U.S. grid for the past 6 decades and produces around 1 gigawatt of power per plant on average.

    Then again, I thought, maybe nuclear power might be less productive than I think it is, so looked up a list of biggest power plants in the world

    https://en.wikipedia.org/wiki/List_of_largest_power_stations#Top_20_largest_power_producing_facilities

    • Number 1 is Three Gorges Damn at 22 GW
    • there is an 7.96 GW nuclear power plant in Japan
    • but 8 GW would be the 10th biggest power plant in the world

    Then I learnt that that nuclear power plant has been out of action since like 2017. It’ll soon(?) be active again but for now the record for biggest nuclear is held by a 7.4 MW power plant in South Korea

    In conclusion, my ADHD medications have worn off and I should go to bed



  • I think you said elsewhere that they are new and that they are photoelectric rather than the radioactive ones.

    I’m purely taking a shot in the dark but I’m wondering if you should try sealing up the hole(s) in the wall that you made to run electric and to mount the detector

    My thinking is that dust might be getting caught up in a tiny draft through that hole and it’s so close to the source that it sets it off. Cause like, if wind hits the side of the house, there can be some positive pressure in the crawlspace which often also means inside the walls.

    I guess maybe somehow there could be some stream or condensation as well. If it’s right by the front door and the humidity is high, maybe the hot air from outside meets the AC air and causes a tiny amount of condensation. Or if you live in hellscape temperatures, maybe there could be some vapor generated because of the hot air.






  • I’m gonna be completely honest. I don’t truly get all the inner working of git. I’m a senior DevOps Engineer and been using git for a decade, but is git is simular to sed or awk for me. I know how to do what I want really well but when shit goes wrong, I’m flying by the seat of my pants.

    A lot of times, I just know what to do to fix things because it’s rote memory with substitutions. But if you needed me to explain upstreams and rebases in actual detail, I’d be in trouble. But it rarely becomes an actual problem to the level where I’ll dedicate time to learning all the advanced stuff.

    That said, I’ve learnt that most senior people also just pretend they get it all but instead are just relying on rote memorization and basic concepts. Anyone else here in the same camp of being a fraud with git?








  • Here’s a link I found that might be good if you are interested in more:

    https://cloudnativenow.com/topics/ephemeral-idempotent-and-immutable-infrastructure/

    https://guymorton.medium.com/persistent-and-ephemeral-infrastructure-as-code-in-aws-42b33939dcf1

    There are different levels of effemeriality. The simplest example I use daily would be an autoscaling group in AWS. Especially if you use Spot Instances to save money, thi gs may scale in and out whenever.

    So if a development team creates a new autoscaling group and I need to get into an instance to test something, unless I add stuff to their IaC, I’m stuck with their configuration. I need to assume that every time I ssh into one of those instances, it’s a brand new instance. But it’d be a big challenge for me to go to their repo and make a PR to alias a command whenever an instance in that resource is created

    Stuff can be even more temporary if it’s something like an ECS task which creates a container with a read only filesystem only when a task is needed to be done. But I don’t want to get too deep in the weeds (or deeper than I already have)

    terraform workspace will at least stick around for a while so you might be in and out of the same system multiple times.


  • {vi} = 2 {vim} = 3 {v=vim} = 5

    I’d need to run vi at least 5 times to have a net gain in saving keystrokes. I’m typically in effemerial systems created by the users of our env, so rarely am I going to gain those strokes back

    But also, why am I trying to apply logic to this? I’ll often cat a file before editing it. This shit is just illogical idiosyncrasies I’ve picked up over the years. I’m probably creating posthoc justifications for insane things I do cause it’s hard to override muscle memory


  • I’ll have to check tomarrow if RHEL and UBI do this.

    Did some quick googling and looks like cent has that alias by default but doesn’t do it when root. Which would explain why I do get inconsistent results with vi. I never thought about it in detail besides just knowing that there are some visual changes. Thanks for the info, I’ll be noticing this now that I know!



  • I’m in DevOps so I’m in a lot of effemerial systems so in practice, I will run into systems where profile hasn’t been set up. Tho I do like the idea of making sure all systems properly have that aliased cause it’d be serial killer vibes to spend hours of time to make sure that I can save a keystroke.

    Tho it’d never make it through PR. Also, wild require explaining to my coworkers that I do this
