From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have one of those 8.1 laptops - I LITERALLY fished it out of a dumpster.
Power consumption is a massive reason to really not do that. Its cheap for a reason, its takes a shitload of power to be shit and you will pay more in energy than you save in hardware unless its only powered on for short periods of time - a server typically isn't.
This is actually something that applies to cheap products too. Was in Asda a little while ago and saw 2 LED bulbs with the same lumen rating. Cheaper one used 3w more and you only saved £1. Running it for 8 hours a day for a year would cost double that saving in electricity. For a server you are looking at almost £2 per watt each year. Does that ewaste look so good to you now?
Some things are absolutely worth getting second hand, but you really should be careful considering the power cost as well.
Quick edit: If you don't need it running 24/7, consider something like AWS too. I love selfhosting but if its not running much it might be cheaper to not bother buying hardware.
This is generally not true. If you are using your laptop as a home server chances are it's going to be idling 99% of the time and laptops are generally pretty good in terms of idle power draw if you manage to disable the screen (or just disconnect it, take it off and find a way to repurpose it)
And in terms of environmental impact saving a laptop from landfill is definitely better since the majority of a computers impact is from the co2 emmissions from the manufacturing process. And this isn't taking into account the likely ethical considerations such as supporting terrible mining practices for resources like cobalt.
these shitty win8 laptops are surprisingly low power and efficient though.
Are you living on a space station? What is this shitload of power? A whole 60 watts? Are you rationing AA batteries to run your household?
What is it with the bullshit fanciful rationalizations people come up with to consume consume consume?
lowendtalk, hella cheap vps with plenty of resources for most self hosted apps, the issue with it is usually storage space but there are ways around that connecting your drives from elsewhere
Warning tho, hella shills too but you could literally make a post asking if certain companies on the site that have active threads are scams and get valid responses that don't get removed or anything so thats nice, like half of the ones I looked at were giving less resources than they claimed
Aren't laptops typically very energy efficient? Low consumption converts to high battery life, which is a priority for laptop hardware.
Some of them consume less than 10W.
Yes actually still sounds good. Raspberry Pis actually have quite high power draw compared to the performance they give. Like sure the number might be smallish but the performance they give and functionality they have is awful compared to even a mini PC which use similar power. Mini PCs btw are actually one of the best options in performance per watt and can still be cheap, plus they have upgradable RAM and storage. A Mac mini is more expensive but will thrash everything else in efficiency and performance per watt, although non-upgradable. Even slightly older laptops will only draw tens of watts when fully charged, vs a desktop or proper server that could pull 100W even at idle in some cases. Older laptops tended to be more upgradable too.
I'm not taking electronics advice from someone who uses the term lappies.
Where I'm from those were 10$ and legal in Quebec.
There's lots of ways to make existing hardware more efficient at the cost of performance. Under-volting the CPU and RAM (or just putting them in "efficiency" mode) can probably save more electricity than you lose in generational improvements. Considering how much more powerful PCs are compared to SBCs, you'd probably still have better performance than an SBC. Also, a more powerful CPU that takes double the power but as a result can idle for more than 50% of the time would be more efficient than a less powerful CPU never idling.
There's a lot of other variables (like idle power draw, efficiency at various power levels, idle latency, etc), but in general I think your statement would be inaccurate at least 60% of the time.
Oh I am not saying specifically get a raspberry pi, personally looking at a bee-link N150 mini PC. It isn't even that much more expensive than the 16GB raspberry pi and as its x86 I can just run normal debian installs in proxmox.

I would say it can sometimes be nice to have an old Laptop for this purpose, you have to slightly over build your solar but can be nice to have a mouse and keyboard attached and monitor, ssh works. Still have an hp laptop with a core i5 2nd gen sitting out in my greenhouse, is a little more power hungry but not terrible on idle, and is nice to be able to configure changes to watering without going back inside or wrecking the zen by bringing phone.
And for some (including me) that's our only computer (other than phone). I just can't afford anything, so all I have is a shitty laptop from 2010 that barely plays 1080p video. I deeply want something better, especially a steam deck, but doesn't look like that'll happen anytime soon (or ever). And then you see people have steam decks that just sit there, unused, gathering dust.... fuck.

The day i can fit the power of a computer capable of emulating the switch 1 in a gameboy shell will be glorious.
Do you mean the steam deck?
We must be pretty close on that by now, I can emulate a number of Switch 1 games surprisingly OK (not amazing, just OK) on my S21!

You probably could with a phone
I mostly agree, and did the same with my second gen lab build - instead of shiny new NUCs like I had used round 1, I bought old off lease Dell Xeon boxes. SO MANY PROS -
- Got them up to 14c/28t each
- They can take GPUs and actually do heavy transcoding/ML work
- They can take up to like, 128GB of memory, which is GREAT when they're all hypervisors
The downsides can't be denied though -
- Even without the GPUs and beefed up CPUs, they are power hogs - the CPU alone uses more than an ENTIRE NUC
- They run HOT
- They run LOUD
The same holds true for off-lease SFF stuff, Lenovo and the likes ...
So while reuse/repurpose is absolutely of the utmost importance, no question - when it comes to technology and how quickly it advances and miniaturizes, a thorough and logical pros/cons list is often required.
I'd add another option though - if you do need what a Pi brings to the table - do you really need a shiny new Pi 5? Is it possible a used Pi 3 or Pi 4 would do the trick, and check the reuse box?
