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.

All computers are single board computers if you take out their guts and tape them to a board

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.

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?

[–] dil@lemmy.zip 1 points 4 hours ago (1 children)

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

[–] dil@lemmy.zip 1 points 4 hours ago

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

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.

[–] Allero@lemmy.today 7 points 12 hours ago

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.

I'm not taking electronics advice from someone who uses the term lappies.

Where I'm from those were 10$ and legal in Quebec.

[–] JuxtaposedJaguar@lemmy.ml 9 points 16 hours ago (1 children)

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.

[–] Korhaka@sopuli.xyz 2 points 13 hours ago (1 children)

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.

The day i can fit the power of a computer capable of emulating the switch 1 in a gameboy shell will be glorious.

[–] Rolive@discuss.tchncs.de 1 points 4 hours ago

Do you mean the steam deck?

[–] ArchEngel@lemmy.ca 11 points 15 hours ago (1 children)

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

[–] M137@lemmy.world 12 points 16 hours ago* (last edited 16 hours ago) (3 children)

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.

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?

The power aspect is a lot bigger of a factor than I would have thought. I had an old computer I was going to use as a server for Foundry that I could keep up all the time, but when I measured its wattage and did the math, it would cost me $20 a month to keep on. A pi costs like $2 to keep running, so it paid for itself pretty quick

I dislike posts like this. Technology moves quickly. PIs are great for hobby electronics where you need a little computer. Want a cheap computer to run a few things 24/7 and know what you're doing? Pi it is. You don't need to run containers on a pi because you have the skills to install the dependencies manually. They cost pennies to run 24/7.

I think of pis as beefed-up calculators. I have made lots of money using a pi zero running code I needed to run 24/7. Code I developed myself.

Having an old laptop with outdated parts taking up lots of space, weighing a lot, and having components like fans, keyboard, and mousepad most-likely soon dying and needing replacing is an additional concern you don't want.

Someone below saying use an old laptop if you're living with parents and don't pay the electricity bill is a bit lame. Do your part for the world. Someone will be paying for it.

Ultimately, use what you want but if you're just starting with servers, use a virtual machine on your computer and log in to it. You can dick about with it as much as you want, and reset back to a working state in seconds.

[–] Allero@lemmy.today 1 points 4 hours ago

Pi's are ARM-based, which still to this day limits the scope of their applicability.

Also, you should absolutely inspect a laptop before buying. Many, if not most, of old laptops will run just fine for the next few years.

[–] areyouevenreal@lemm.ee 8 points 13 hours ago* (last edited 13 hours ago) (1 children)

Laptops don't even use that much power. You guys are really not into home labbing or as good with tech as you think you are lol. Lots of people run older real servers and desktops as home servers. They use way more power than laptops. Raspberry Pis sound good but use progressively more power in each generation, and still struggle to compete with mini PCs and even older laptops in performance. They also never had good performance per watt. In performance per watt basically nothing beats a Mac Mini, though other mini PCs are also good. Laptops aren't bad in energy efficiency either. They are literally designed to run on battery so have as little idle draw as possible. They would be comparable to a mini PC if you turn off the display.

Edit: Modern RPis apparently use 25W, which is firmly in the territory of what a laptop would use when not running the screen or charging the battery.

[–] lilith267@lemmy.blahaj.zone 3 points 5 hours ago (1 children)

Rpi uses 25watts? My old acer 6th gen laptop has a 15watt TDP and remains around 8watts 24/7 even with my services and without disconnecting the internals. My 8th gen laptop pulls 6watts with the screen on. People here saying older laptops arent a good choice are insane considering the ~$100-300 diffrence between an ewaste laptop and dedicated minipc + backup power bank (laptops have internal batterys you can easily replace when they go bad)

[–] dil@lemmy.zip 2 points 4 hours ago* (last edited 4 hours ago)

yeah even the best overheating overpowered gaming laptops have way lower power draw compared to your average desktop?

[–] gamma@programming.dev 11 points 17 hours ago

Yeah, theres a lot of old old laptops which make no sense to run. But there's a growing crop of more recent used devices that are only being sold off because they don't support Windows 11, and the power efficiency story changes there. The OOP mentions "8.1 lappies"; my main laptop has a 15W 8th gen which is only in the last year starting to feel less appropriate for desktop use. (And honestly, a RAM and storage bump will probably get me another couple years.)

For environmental concerns, youve got to tax new devices with manufacturing costs as well.

100% agree about VMs though.

Or get a used thin client (e. g. HP T620, T630, T640 or Dell Wyse 5070). Cost: ~40-100$. Biggest advantage: Passive cooling, i. e. they're absolutely quiet.

[–] Allero@lemmy.today 1 points 4 hours ago

Wanna get something like this and a large SSD going forward. Make a silent NAS out of it, and have it in my bedroom without issues.

[–] jol@discuss.tchncs.de 120 points 1 day ago (12 children)

It's not just the size constraint. The power usage is significant...

[–] areyouevenreal@lemm.ee 2 points 4 hours ago

Fake news. Modern RPis need up to 25W PSU. Even old laptops could idle lower than that, as otherwise they wouldn't be able to get significant battery life. Turning off the screen will also really lower their power consumption.
