Read the article. The trend started in 1990, a time where wfh meant assembling ballpoint pens or prostitution.

It's not just capitalism. I'm from east Germany and you wouldn't believe how much crap was buried, fumed into the air or pumped into the water in the name of peace and socialism.

Don't forget, Chernobyl happened because of a cost saving measure.

BTW, you forgot alcohol, tobacco, vapes, stress and enforced sedentary lifestyle in your cancer list.

I mean, look at Reddit. Huge uproar last year, nothing happened really.

Pretty much every service, platform, app has become worse over the last two or three years. But people keep using them. And not for a lack of alternatives. They are actively hostile against change and many really don't care. They are so used to being fucked over, squeezed for pennies and bombarded with bullshit ads, that they gave up.

The same thing happens in politics, btw. People just vote whatever - if at all, because they already expected to be fucked over. All those activists you see on TV or online are a tiny minority.

But not for us.

That's what I meant by larping. The vast vast majority of us here would probably not even notice if their systems went down for an hour. Yes, battery backup has its purpose. In a datacenter.

I mean, what's on the line here in the worst case? 15min without jellyfin and home assistant? Does that warrant taking risks with old batteries or investing in new ones?

That equation might change if you're in a place with truly unreliable electricity, but I guess those places have solutions in place already.

That's typically a feature for servers or business desktops. Maybe your laptop has it, just look into the BIOS.

As I wrote in my other comment: try to be realistic about your needs. Chances are, pressing the power button every few months (if at all) is perfectly fine for your use case (and most others here).

God, I hope so.

AI apocalypse sounds much better than anything the current timeline can offer.

And how much need is there for a UPS in this scenario - realistically.

Some of the people here take their admin-LARPing a tad too seriously. Most households have reliable enough electricity, and even if there's an outage once every quarter, would a dead battery even help?

I advocate for being realistic with one's own needs. Don't build a five-nines datacenter for a glorified weather station or VCR.

In case you didn't already do that: remove the battery. It's probably dead anyway, you don't need it and it poses a potential (albeit low) risk.

Maybe Israel could inject bleach into these sites?

She could start by abolishing all that royal tax money wasting crap.

As an expecting father, I hate you a bit for bringing up yet another fear of fucking up.

 

I have a small homelab running a few services, some written by myself for small tasks - so the load is basically just me a few times a day.

Now, I'm a Java developer during the day, so I'm relatively productive with it and used some of these apps as learning opportunities (balls to my own wall overengineering to try out a new framework or something).

Problem is, each app uses something like 200mb of memory while doing next to nothing. That seems excessive. Native images dropped that to ~70mb, but that needs a bunch of resources to build.

So my question is, what is you go-to for such cases?

My current candidates are Python/FastAPI, Rust and Elixir, but I'm open for anything at this point - even if it's just for learning new languages.

 

I asked a while ago, how to build an automatic light switch and finally got around to actually building it.

My board is an ESP8266 mini D, and ignoring all the sensor parts, my problem right now is powering the actual light.

It's just a small LED array and I connected it directly to the 5V and GND pins (controlled via a transistor).

Measuring from the wall (so including the PSU), this whole setup pulls about 3W (so far expected), however, one small component close to the USB connector gets uncomfortably warm, and I'm not sure, whether that's ok.

The hot component is one of the two small thingies circled in the picture. I thought the 5V get pulled directly from the USB plug, so I'm not sure, why there is any circuitry involved.

 

I'm trying to build a very simple, stupid light switch for my grow light. Essentially, I want to turn on the light, if it gets too dark outside, so that my plants can survive the northern winter.

Since I'm a software guy, my first thought was an ESP32, but that seems excessive.

My current approach would be something like this: https://www.ebay.com/itm/313561010352 In conjunction with a relay, both powered by a USB-PSU.

If the light level is low enough, the logic DO pin should send a signal and that should be enough to trigger a small relay, so that the relay then closes the circuit to switch on the lights.

Is that idea completely stupid? With electronics, I'm usually missing something very obvious.

The lights themselves are already just usb powered and only draw 5W, so that shouldn't be problem.

What I'm concerned with is the actual switching. Is the logic signal "strong" enough to activate a relay? Would simple transistor maybe sufficient?
