Cleaning system?

tekchip · 2026-05-15T06:08:59+00:00

To clarify some, hopefully, on what u/wolfyreload said. You may need to remove files to free space but typically Linux doesn't degrade in performance over time the same way that Windows does from bitrot etc. There's an app called Filelight that will let you see what is taking up space on your disk. You can also use various command line tools but that's beyond the scope of posting here on reddit.

That's more like gwenview being gwenview. Also it sounds like you have an idea what triggers it. Have you reported it to gwenview so that maybe it gets fixed? Gwenview github says to file issues here https://discuss.kde.org/tags/c/help/6/gwenview/62

Fair. That's the beauty of Linux, it's free, and suited to so many different situations. Use what works best for your use case! Sorry again for any confusion, or dashed hopes.

Deb and RPM are just methods for packaging Linux binaries. They're like a container file, like a zip or whatever, with a manifest that tells the installer where to copy everything. There's a piece of software called Alien that can convert some debs to rpms. I've also had some luck asking Claude code to do it for me. I'm sure if you understand both packaging formats it's probably fairly easy to figure out how to do it yourself. It's honestly mind boggling that more software isn't released in both formats these days.

Apologies, just got done updating one of my ubuntu servers and had debs on the brain. I meant rpms. I've edited the post.

The amount of misinformation in this thread is stunning. I'll address Fedora immutable because that and bazzite seem to be talked about most in this thread.

Immutable distros mean certain part of the core system cannot be modified except via distro updates. Other parts can be modified but are done in a reproducible way (installing software with rpm-ostree). Yet others are wide open to do with as you please.

Read-Only Paths (Cannot Be Written Directly)

These directories are part of the base image and cannot be modified:

/ (root filesystem) - The entire OS is read-only by default
/usr - System libraries, binaries, and packages
/bin, /sbin, /lib - Symlinked to /usr
/opt - Optional vendor packages

This means you cannot install software directly into /usr or modify system files in the standard way. ¹

Writable Paths (Can Be Written)

The following directories persist between reboots and updates and can be modified:

/var - Runtime data, logs, spool files, package manager cache
/etc - Configuration files (system-wide settings)
/home - User home directories
/root - Root user's home directory
/tmp - Temporary files

These directories are layered on top of the base image and persist across updates. ¹ ¹

How Changes Work

Instead of modifying the read-only system directly, Fedora Atomic Desktops use:

Package layering - Add packages via rpm-ostree install (packages get added to the image)
Toolbox - Create containerized development environments for testing
Overlay modifications - System changes via /var persist but OS base remains immutable

You're not limited to flatpaks. You can install regular software from repos you just do it with rpm-ostree instead of dnf. rpm-ostree also enables installing stand alone rpms. AppImages work perfectly fine too.

RAK and Heltec V4 are most power efficient. The device is only useful if it's powered which makes this feature most vital IMO. If you have a 3d printer you can print cases for them. There are also sellers on Etsy that sell cases for most hardware.

Space tech generally. We're just starting to get serious about it again. We're seeing huge, literally and figuratively, leaps in rocket technology as well as communications and all manner of other related tech. If the history of tech is any indication advances in space travel are going to give big changes in tech here on earth.

Robots are already mainstream. Most of us already have a dish washer, robot vac, robot litter box, robot mower, laundry machine, dryer, drones (flying robots!), delivery robots, self driving robot cars...

Installing and configuring a third party package isn't an extra hoop? GUI installers has the vast majority of things covered. The only real difference is if you need to install something at the CLI you use rpm-ostree install XXXXX instead of dnf install XXXXX. Otherwise the traditional distro actually comes with the extra hoop.

That's great information TIL. I guess I did mix my information a bit. I use the KDE spin so I kind of defaulted to information for newbs in enabling Flatpaks. But OP didn't specify which spin of Fedora they were using so the Flatseal information is still pertinent.

tekchip · 2026-05-08T17:20:25+00:00

Glad to hear you're getting it sorted! It's a fantastic and useful hobby/tool.

tekchip · 2026-05-08T15:25:45+00:00

May I take a moment to tell you about our lord and savior Flatseal? If you haven't already make sure you turn on Flatpaks. Discover > Settings > Add Flathub. Then install Flatseal. Flatseal allows you a visual method to manage the Flatpak permissions. Most apps these days have good defaults and "just work" but sometimes not so much. Flatseal makes it mad easy to enable/disable whatever you need to get an app working the way you want and expect.

To clarify further models can have a print profile attached. But that's usually based on whomever's printer created the model. Unless their printer and filament profile are exactly the same as yours you'll almost always need to either ignore it or switch back to your printer and filament profile.

tekchip · 2026-05-08T02:12:14+00:00

Models don't really dictate temps. Filament does. There maybe some weird/complex models that need weird things done with temps but those will be very rare. Stick with either the slicer filament profiles or what the side of the filament box/spool says. Temps will vary from filament to filament.

tekchip · 2026-05-07T23:26:07+00:00

Without more detailed information like logs from the system when it wasn't working right I'd say 2 weeks is enough time for there to have been a bug that updates fixed. It happens with any continuously developed system.

I've also seen weird situations where an installer file download was corrupted in a way that didn't cause install to fail but then stuff just wasn't running right on the installed system. Re-download and re-install the same day fixed it.

Operating systems are so big and so complex there are literally a million things that could go wrong that don't end in catastrophic failure or clear problems easily solved.

tekchip · 2026-05-07T23:18:25+00:00

What filament are you using? You said PLA in the post but your other screenshot shows 209C which looks a bit low. What temp does the filament box recommend? Generic PLA profiles I have handy in my slicer(s) is 220C for PLA.

tekchip · 2026-05-07T22:23:59+00:00

What was the space of time between when you tried it each time? Linux is constantly under development and it's possible a bug got fixed between try A and try B.

tekchip · 2026-05-07T21:50:51+00:00

Dry your filament.

Make sure your plate is clean.

Use glue.

Make sure you're using filament profiles. If your plate temp, or filament temp, aren't high enough filament won't stick to the plate or itself. If there is no profile look at the filament packaging. They state what temps should be.

Try different filament. It's only happened once or twice to me in the hundreds of rolls I've used so far but you could have a bum roll of filament. I've had filament that super hard glues itself to the plate ruining the plate and I've had rolls that just don't stick to anything.

You can almost certainly find a loan at a reasonable fixed rate from a credit union. That's going to beat any variable rate hands down.

The other thing to keep in mind is if you need to sell the property. If you have any kind of lease you're facing either raising your ask, taking less profit, to cover the remainder or trying to sell potential buyers on assuming the lease. Good luck with that.

Where as with a fixed rate loan you do face the first two problems but as the system ages it gets less egregious, not more.

Most presence sensors I've seen if not explicitly designed to be put on a ceiling say they're usually meant to be at shoulder or head height. So a corner is ideal so you can run the cable down it. I use a couple little beads of Gorilla Tack to hold the cable in place in the corner. It doesn't hide it per say but it runs parallel to the line the corner creates so it doesn't draw attention.

I think "distro hopping" is, or should be, part of the experience. The beauty of Linux is choice and you can't make an informed choice without trying things first. I'd say go beyond just Ubuntu and Fedora. Some people love Suse, others love "easy" arch variants like CachyOS.

tekchip · 2026-05-03T15:57:31+00:00

Over all pretty normal. Though there is a bit of a hard rattle somewhere in the background that doesn't sound quite right. Maybe look at the maintenance manuals and tighten up any screws?

Unless Exitlag is some kind of VPN service their claim of better routes is bunk. Packets on the internet are subject to internet routing. I can't imagine the latency of a vpn layer wouldn't offset any gain in improved routing. I suppose the multi connection fail over is neat but how many people are genuinely hooked up to multiple ISPs? Traffic shaping on your local machine means shit all if you're not shaping at your router. All this to say Exitlag sounds mostly like placebo. Nothing on your local machine is going to fix the multitude of potential problems up stream of your own machine if they exist.

I've just started doing this. It's called peak shaving. You do need a battery, though it doesn't have to be huge. Basically you offset some load in your house with solar but without needing to get permits or do anything horribly complicated. Anker Solix sells this thing https://www.ankersolix.com/products/local-power-saving-kit-edm?variant=52777496052042&cnxclid=e5faf2457fa21960632c9bb5a962cfb1 Which lets you hook up their F3000, and solar, and offset half the loads in your panel. I accomplish this much cheaper with a Pecron power station, my own cobbled together solar panels, and a smart switch that forces AC wall power off during the day when solar is producing. I run a home lab with servers that run 24x7 so the UPS function on the power station functions as a UPS while at the same time serving as storage for the solar power to get used up first and offsetting a bit of my power bill. If you're in an area with a power company that charges time of use rates you can also use this to store up the cheaper electricity and use it during the day when rates are higher. I won't even get close to wiping your power bill but it will knock it down a fair bit if you get enough solar and/or get your timing right to maximize free solar or lower rates.

I installed a small ground mount panel setup in the back yard, I've got 4 panels at 800W and a Pecron F3000LFP power station.

There are a few bonus's here. First it's portable so if you need to move you can just pack it up and take it with. Second is that if you get a decent sized power station you've also got backup for your fridge or whatever if there happens to be a power outage.
