If the vast majority of people are affected, is it really "extreme" anymore?

Nope, 65th place, slightly behind the US and the country of old men: Albania.

And a whole lot of content that I frankly would have preferred not to have seen.

When you're 12 and your parents have no idea what you're doing, you'll end up in very dark corners.

It's the same in China.

And who does that?

I think you don't really get my point. I'm not arguing that there are no ways to archive data. I'm arguing that there are no technologies available for average Joe.

It is hardly a good strategy to basically set up half a datacenter at home.

Thin concrete slabs are extremely brittle.

Is it? It's rather expensive and would you really know, if the data is gone or corrupted?

You'd have to download every single file in certain intervals and check it. That's not really low complexity.

But what actually is "archival"?

Like, what technology normal person has access to counts at least as enthusiast level archival?

Magnetic tape, optical media, flash, HDD all rot away, potentially within frighteningly short timeframes and often with subtle bitrot.

Well, actually you're kind of wrong, at least in some contexts.

So I'm not sure, how that works in other countries, but here in Germany, a large bid for some public contact has to parrot the requirements. The process includes a bloke essentially ticking all of the boxes in their request, and if you say (just for example) "we will deploy that in our k8s cluster" but they require a cloud ready solution, the bloke will not tick the box. Yes, that's incredibly stupid.

Apart from that, who reads the bid texts? Not technical people, but bean counters and MBAs. The technical people on the other side are only asked for comment, they have no say.

I wish you would be right, but in a world full of people desperately trying to justify their existence, fluff is essential.

Most "professional" writing is just a bunch of phrases interspersed with a few chunks of information.

I'm involved with bidding and grant proposal stuff for software and it's 90% empty words. I draw two diagrams and a page of text, sales deletes 60% of the text, misinterprets the rest and then puffs it up to 30 pages.

Why exactly does MS gaming employ over 20.000 people?

And when people started writing books instead of memorizing epic poems.

 

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?
