I have an old, high-end laptop that's a lot better than a Raspberry Pi in all respects, except being 32bit.

It's currently running Ubuntu (for convenience; I did find it lower maintenance 8 years ago) as a simple syncthing backup mirror for the devices in the house.

I'd like to use it for every LAN server situation I can and whenever I need a linux but
More and more packages are complaining with "no installation candidate".

I thought Gentoo has to be an option, using source and compiles but maybe I'm wasting my time and what I really need to do is get a Raspberry Pi and submit to landfill.

Recent packages I wanted to run on Ubuntu but couldn't:
- mautrix-whatsapp
- imageproxy
- archivebox

Engaged-Unbundle,

You have two separate questions here.

There is building and maintaining Gentoo.
There is running Gentoo.

They need not be on the same system. Even if they are, distcc may be useful.

There are no available ebuild for these currently on Gentoo. On the other hand, you could use Docker for these specific applications. (Maybe even on your current Ubuntu installation)
From a quick search : (might work or not)
https://archivebox.io/#quickstart ( https://raw.githubusercontent.com/ArchiveBox/ArchiveBox/master/docker-compose.yml )
https://github.com/willnorris/imageproxy/blob/main/Dockerfile
https://docs.mau.fi/bridges/go/whatsapp/setup/docker.html

If you really wish to use Gentoo on your 32bit laptop, then you could go with a minimal setup, with only basic service, docker-cli. You need to figure out if it's worth it though and most likely you'll need to use it as minimal as possible to minimize the compilation, rebuild etc.. especially on old hardware. (An other option here is to build your packages on a chrooted Gentoo 32bit install on a more beefy hardware and then pull those packages on your 32bit laptop)

There should be distcc SAAS. Being able to rent compile time this way would be very handy. Is there anything out there? I only have a slightly old MacBook but with OSX to donate to this temporarily. Is this a thing?

Engaged-Unbundle,

distcc needs lots of network bandwidth, so its not a good candidate for SAAS.

As a first approximation, consider the size of all the .o files in your build directory after a package has built. A distcc-as-a-service would require downloading all of those (assuming you dist'd out every file, and built none locally). It would also require uploading every source file in post-processed form. Since we assume you are severely CPU starved on the client (which is why you want to distcc-as-a-service at all), you probably don't want to spend much CPU time compressing those post-processed files, which means they are quite large on upload. Most home users have poor upload bandwidth to the Internet. distcc bandwidth requirements are fairly easy to satisfy on a home network, but not when the peer is at the far end of a consumer ISP.

This doesn't even consider that such a service requires you to trust the provider not to miscompile anything, whether accidentally via bad flags or maliciously.

I continue to maintain 32 bit Gentoo on an old LOW-END laptop; Celeron M, 4 GB RAM. I don't watch it compile, but it does quite well. I maintain three other 32 bit Gentoo systems on now ancient desktop machines.
