So do Raspberry Pi?

[–] [email protected] 1 points 1 day ago (1 children)

Battery charging circuits don't operate continuously when the device is charged. Pi also still needs a PSU, typically a phone charger, and for a server application would need an SSD or HDD in most cases. SD cards have lower performance, write endurance, and capacity after all. A single raspberry pi couldn't match even a somewhat old laptop in performance. In terms of actual efficiency (performance per watt) Pis don't do that well as they are using cheap processors made using old core designs and even older process nodes. Even the latest Pi 5 uses a 16nm process node with a core design from 2018. A 10 year old laptop might have 14nm process node which would be better. This means that a laptop would have more performance, so even if it had more power consumption at peak it could still end up with significantly better performance per watt, and that extra performance allows it to idle more often as it spends less time processing requests.

Of course the ultimate in performance per watt is always going to be a modern high power server or an Apple Silicon device. Mini PCs can also do well for home use, and are much lower power so better suited to less demanding usage, and have the best performance per watt for consumer devices. The M4 Mac Mini for example is pretty much best in class in performance per watt, and low power consumption at the same time.

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.

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

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.

[–] [email protected] 3 points 2 days ago

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 2 days 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.

[–] [email protected] 4 points 2 days ago

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.

I am having audio issues on NixOS. I have tried enabling all firmware. I've also tried both pipewire and pulseaudio. The audio is confirmed working on CachyOS live image.

Here is the error message found in the system log:

Here is configuration.nix

 

I created a hyprland and waybar configuration using nix, and neither seem to actually apply. Why is this happening?

I am looking for a YouTube alternative client, where I can ideally import my subscriptions, and possible even like or comment on a Linux computer. Does such a thing exist?

 

First off I am in England in the UK, so that's the medical system I would probably be using.

I've had significant issues with executive function throughout my life, but especially in the last two years of my integrated masters degree. This includes organization, as well as staying focused. I've had issues with losing things, multitasking, procrastinating, racing thoughts, and other issues in the other areas of life as well. I am thinking of going back to do a PhD or starting my first full time job, and am worried that I will really struggle this time.

I got a diagnosis of Asperger's before you could officially have a dual diagnosis under the DSM. So even though some of initial paperwork said I had significant evidence of ADHD, I couldn't actually be diagnosed with both so I guess Asperger's took precedence. This all happened when I was like 4 or 5 years old.

I am thinking medications or maybe therapy might be helpful, but I don't know if I need the second diagnosis to get those. From what I understand the NHS (UK public health system) has long wait times, and going private might be expensive. Additionally going to a psychologist, and talking about stuff with my family seems scary.

Additionally I have issues with sleeping and waking that probably won't help get all of this organized, and I probably need to get this addressed too. I understand that both ASD and ADHD can cause sleep issues, so maybe getting treatment for those would help.

Sorry for the long post. I hope this is also the right community for this as I wasn't sure where to post this.

Edit: I also have hyperfixation/hyperfocus/special interests out the waazoo, but I didn't know if this was relevant as that's also a part of having autism.

 

I am looking for a way to play HDR content on Linux. From what I understand KDE 6 has experimental support for HDR, but isn't available on Pop OS 22.04. Apparently Cosmic desktop will support HDR when it's released, but I don't know if the experimental version will.

Can anybody help me here? Will I need to change distro?

 

Is there a way to move distro without loosing data in /home? I am currently running Pop OS and want to move to Nix OS while keeping the data. Normally I could use an external hard drive or my server, but most of my equipment is in storage at the moment. Current partition setup is using LUKS and LVM with ext4. I am guessing there is a way to manipulate the LVM to make it work by adding another partition and installing into it.

I know this is probably a convoluted idea. I am trying to avoid spending money an another external drive.

 

I am finding it difficult to fill in forms made with MS Word in LibreOffice. The formatting seems to end up all wrong among other things, and LibreOffice feels slow and clunky to use.

I've tried OnlyOffice, but it tends to crash and be slow as well.

At this moment in time I am trying to get MS Office 2010. Is there a better solution?

How do I fix my home dir with nix? It seems I have messed something up and now I can't install home manager. Anytime I try to install a package with nix-env it gives this error too:

error: this derivation has bad 'meta.outputsToInstall'

 

I have a calibre server setup on my home server and was wondering how to sync it to the version on my desktop so I can upload books to an ereader using USB.

 

Trying to figure out how to setup an aria2 server. It seems to rely on XDG dirs which isn't normally setup on LXC containers. I don't want to setup a whole GUI VM just for one application.

I have been having issues using real debrid. One of the big issues is downloads getting stuck continuously retrying. I think this is because I am using 5G internet that has issues with latency and occasional packet loss. Similarly I get buffering issues when using Stremio.

Another problem I am having is with the permission set by the real debrid client if I use the docker version. It doesn't allow for changing the UID and GID the real debrid process uses. This causes problems for the other services, though I can work around this using a manual installation in an LXC container.

Does anyone with more experience know how to fix this?

Edit: I can't edit the title to fix the spelling. You will just have to deal.

Edit2: Fixed the permission issues. Also managed to work out that the problem isn't 5G. The download client is just bad. Apparently you can use external downloaders, but this requires deploying services like aria2c, which it turns out is actually quite hard.

 

I am a bit lost as to how you use authentik to do single sign on.

I can connect things that have external access quite easily using the reverse proxy provider that's built into authentik. I am struggling with how I would connect things that are on a docker network and can't be accessed directly. Normally with nginx proxy manager I would put it on the same network, but I don't think this is correct for authentik. Am I supposed to create a docker outpost?

Other people are using authentik + nginx proxy manager and I am a bit lost why they are doing that.
