I mean sure. If you want to compare actual efficiency then performance per watt is the metric. Here a laptop would easily win as it has higher performance for similar power. The TDP of a U class processor is only 15W normally. It would obviously help to disable things like Turbo Boost as well. Said laptop having more performance wouldn't need to stay at high power states for as long as the Pi either as it takes less time to process requests. Returning back to idle faster is a big advantage.

Bro please. I understand you can host very small stuff on less powerful Pis. I used to host some stuff on a Raspberry Pi model b myself. Stop tooting your own horn. You couldn't however host all the stuff I use or even most home labbers use on a Pi zero with modern software. I doubt it could run Jellyfin, an *arr stack, ollama, nextcloud, etc all at the same time. Probably you would also have to drop using containers which would be less secure and easy to deploy.

What's the performance per watt of a Pi Zero anyway? I am sure it's low power draw but I doubt it's actually efficient.

Probably for as long as raspberry pis have been around. There have been plenty of scares with phone chargers exploding, and that's what a raspberry pi is powered from. Laptop chargers haven't had many issues in the past decade or so.

Yes it's relevant. I have been one of the people making it. However they didn't specificy what they were actually comparing in their first comment. So it ends up they are saying something false. Your average laptop could easily beat a raspberry pi in performance per watt.

Benchmark it and tell me. The truth is that most RPis are made using older process nodes to reduce costs. Laptops are often made using the best avaliable process node and core design. A modern raspberry pi 5 uses a 16nm processor with Cortex-A76 design from 2018. A laptop in 2015 would be using 14nm Broadwell processors from Intel. This was a time when 15W U series processors were gaining popularity, so sustained load power consumption is quite low. A 2015 laptop is 10 years old, and wouldn't run Windows 11, so will be ewaste this year. Same with a lot of 8 year old machines actually.

Are any of them actually that good in efficiency though? Like a Pi 5 is probably the best in performance per watt, but it also has the highest power consumption. Realistically you wouldn't self host on anything older than a Pi 4 anyway.

[–] [email protected] 2 points 1 week ago

Yet a Mac Mini does exactly that. Or like any Intel N100 based mini PC or laptop. Those also have way better performance, IO, and software compatibility. Raspberry Pi's fill a certain niche, but efficiency isn't it. At least not anymore.

How many people keep up with this misconception RPis are ultra efficient? They are bargain basement SoCs. The power draw isn't that low (25W PSU), and the performance they deliver isn't great. They are all made using older process nodes and techniques that result in less efficient processors. Add those together and you will find they have less performance per watt than all modern laptops with the screen turned off, and less than most Mini PCs. Mini PCs and other SBCs are where it's at for efficient home labs. If you can find a Mac with Apple Silicon for cheap they are even better. Everyone in the home labbing community pretty much knows this by now. I struggle to understand why Lemmy hasn't got this through their brains. I think it's partially the miconception that ARM is always better, and partially down to people not understanding that low maximum power draw and efficiency are the same thing. Not even thinking about idle power or performance per watt.

Laptop chargers are no fire hazards anymore than raspberry pi PSUs are. In fact probably the RPi parts are worse as they are built down to a cost.

These things are removable with a screwdriver in most cases. If the battery isn't completely dead it's actually useful for backup power.

A raspberry pi is not as efficient as people are claiming. They need up to 25W PSU for a reason. Laptops can idle lower than that certainly. Something like a MacBook Air M1 would idle in single digit territory, as would any netbook basically ever made. Only really high performance or older laptops have idle power draw issues since battery life is a major selling point of a laptop. Said laptop is probably also faster than a raspberry pi. The people building Pi clusters are really not doing themselves any favors with power efficiency.

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.

 

I am currently living with my parents and we have just started an Internet contract with a 5G wireless company.

The issue is the MFND settings are behind a password and likely not allowed access by the ISP. Even if they weren't doing port forwarding on 5G likely isn't possible because of CGNAT. I think I can use cloudflare tunnels or tailscale to get around this, and not many things need to be directly accessible from the Internet.

The more annoying thing is that setting DHCP reservations likely isn't possible without getting access to the settings. It's going to make setting up static IPs difficult too.

Before anyone asks fixed line Internet almost certainly isn't practical in this area. Getting our own modem while possible is more expensive and potentially difficult, and would mean cancelling the contract.

Is there a reasonable way to work around these issues?

Any help or advice would be appreciated.

 

Hello based people of lemmy,

I have recently started trying out BSDs as an alternative to Linux and found out that Spotify isn't supported. Before you say try it in a browser this doesn't work as spotify has DRM that doesn't work on BSD OSes.

Now is there a way to stream music similar to Spotify? I know there is a downloader program available.

Furthermore do you know what self-hosted options are available? I already have a basic *arr stack and am always up for convoluted server and Linux hijinks.

 

I am having issues with Jellyfin not finding ffmpeg on FreeBSD. Is there any solution to this?

 

I have been struggling to stabilise things in my last few brewing attempts. I had been using a combination stabiliser (sorbate and sulfite) from the department store Boyes. It doesn't seem to work.

I know have sorbate powder and I already had campden tablets. I am wondering how you dose them correctly. From what I understand it's dependant on the ABV and the pH. Is there an easy way to calculate this? I take it there is no easy and cheap way to do a free SO2 test.

I am begging to think buying a sous vide and doing pasteurization is easier and more reliable at this point.

 

I've setup proxmox, and switched to the community repos.

The issue is the kernel it's now running doesn't have a headers package in said community repos. This means I can't install nvidia drivers properly. I can only install older kernel versions and headers. I tired removing the newer kernel and it tried to remove proxmox-ve meta package.

Do I need to remove proxmox-ve package and install community version or like what?

 

I have some probably dumb questions to ask about marxism and wasn't sure where to go. Is there like a ask marxists or debate marxists forum? Anyway

What and how many branches of marxism want state socialism during the socialist transition period before Communism? I was under the impression that all (or most) leninists wanted state socialism during this period. I have since been told that Trotskyists don't want this. Is this correct if so what do they want instead? How does this all relate to vanguardism?

Furthermore how does marxism define a state? Is this different from how other groups define statehood?

I still don't fully grasp the difference between marxists and anarchists. I thought the difference was mainly that anarchists don't want a state, and encourage mutual aid. Now that I hear not all marxists want a state I am pretty confused.

 

Chinese ROMs come without support for many languages. Even when using English there are still things which are in Chinese.

The people selling the devices on AliExpress are selling then with a "global rom". The issue here is that the rom doesn't exist officially. So no updates are available and you don't know what's actually inside it.

xiaomi.eu provide a modified version of the Chinese rom with language support and some other things. The issue is they charge for this through patreon for any mediatek devices. You have to keep paying if you want security updates. This is immoral and probably illegal as they don't own MIUI or Android and copyleft is designed to prevent this kind of thing.

To add insult to injury they started offering some mediatek roms for free. When people stopped paying the patreon they removed them from the download sites.

Shame on them and shame on the AliExpress sellers. If anyone knows a good course on building android roms and reverse engineering them let me know. Maybe I can fix this situation.

 

I have been trying some of the immutable linux OSes because from what I understand they are more modern and feature better security and reliability. What I have found so far is shocking. Half of these don’t support my laptop (probably because it’s nvidia optimus). Some I tried like guix were very difficult to install, configure, and use with sprase documentation. Good luck trying to use KDE, wayland, or pipewire for example. BlendOS was notably better and could at least run on my laptop but chocked with nvidia driver issues.

I have switched to pop os on my laptop for now but looking at alternatives and what to install on my desktop.

Was running out of Kveik yeast (my last brewing yeast), and too impatient to wait for more to arrive so decided to co-pitch the one gram I had left with some sourdough starter.

What does anybody think will happen?

The starter has worked well at fermenting strawberry wine in the past, but it was looking a lot less healthy this time.

Honestly this was an impulse decision to do this but I will be interested to see what happens. Maybe it will sour? That would be exciting.
