You're probably counting cached memory then. Or running a load of services.

barebones wm, no frills, no applets, no animations. it wasn't really something I'd choose to use every day, but it worked. The kernel on its own barely uses any memory so there isn't much you can shave there anyway.

I've gotten arch down to two digits memory usage without touching the kernel

Might as well stop beating around the bush then https://www.linuxfromscratch.org/

The problem is that there isn't really a 1:1 equivalent, despite the terrible management it still scratches an itch no other platform does (at least so I'm told, not being on twitter myself). However things like this are what's driving away twitter's main advertisers, meaning the platform's finances are going to be worse and worse the longer this goes on.

The lens is "just" the glass part that focuses light onto the sensor. The sensor is what actually captures the image. Not all sensors are the same, especially between phones, and therefore they can't just be swapped around like lego bricks. Now, if the industry were more standardized and phones were designed to be more repairable, this may not be the case... but that's not the world we live in right now. @wanderingfool2 data scrapes from refurbs can be solved by 1) having the drive be encrypted, which I think is already the case on iphones, and 2) diligently writing it over with random data. The latter isn't something you can easily do if you're a third party, but it could be done by Apple if they really wanted to. Though as I mentioned, with the way iphones are made there are many reasons why trying to resell them all would probably be a fruitless endeavor.

I don't think it's that easy, you'd have to design said phone (and its camera sensor) with those lenses in mind. Almost every iphone generation uses a different lens, too, which makes this even harder. And I doubt Apple is eager to share their designs and specs with a third party. Again, you'd have to rethink the whole production process with a greater focus on durability, repairability and reusability for these changes to work.

Apple is far from being alone in doing this. To some extent, demanding all iphones turned in to Apple be refurbished and resold no matter how outdated they are is probably unreasonable - however proper and environmentally friendly (when possible) disposal should be legally mandated. There's also the fact that these devices (not just from Apple) are designed to be hard to repair and to be obsolete within a few years, which worsens the ewaste problem at the root. A lot of people should probably be more mindful of their devices and try to make them last, but there's only so much you can do when, by design, they aren't built to last.

Likely because it expects your system to have old packages. This, by the way, is the reason Arch Linux officially discourages partial upgrades or downgrades. What are you even trying to do that requires an old unsupported kernel? Will 4.19 LTS do? https://aur.archlinux.org/packages/linux-lts419 https://aur.archlinux.org/packages/linux-lts419-headers If you MUST have 4.20 I would recommend taking the 4.19 PKGBUILD from the aur package and changing it to pull 4.20 instead, the required steps are likely the same. It's worth noting that your system may have packages installed that OP's does not. Also you may have different versions of various packages.

yes

What do you expect me to give you? A full list of every service that comes preinstalled in Ubuntu and what they do? systemctl list-units --type=service just compare the two and look up what the extra services do. And it's certainly not the google account integration that is slowing down your boot, if it really is slow. I haven't used Ubuntu in a while but I don't remember it ever being particularly slow. i3 is a window manager, not a desktop environment. It doesn't ship with applets, icon sets, animations, themes, settings menus, a login screen, launchers or anything of the sort, plus some preinstalled utilities and variety programs. DEs come with all of those and some extras for user choice, because they have to account for most users. Try pulling down the entire plasma metapackage and see if your system doesn't become just as "heavy" as manjaro.

There's no such thing as a "higher level distro", what you're referring to are derivatives. The point of them varies but generally they spawn when a group of people like a given distribution, but want to change a few things. For example manjaro is for people who generally like using Arch, but prefer a less involved installation process and having some sensible defaults out of the box. Artix is mostly Arch but without systemd. And so on. Ubuntu has almost nothing to do with Debian anymore, it's not just Debian with a nice installer. Mint is an effort to have either of those distros with an out of the box light and convenient desktop... maybe it's not to your taste but saying it has no reason to exist seems a little much. Linus was trying to run non-native software through a compatibility layer, using a distribution that is not that widely used (mainly because it's designed by a manufacturers specifically for their hardware) and expecting it to magically work without a hitch. He said at the time that this just indicates Linux wasn't ready for mainstream gaming, and you know what? I agree - if you want to run windows games without issues then just use windows, duh. But I wouldn't blame that on Linux or pop_os... it's just an unrealistic expectation. Personally I wouldn't recommend pop_os over Ubuntu if you don't have a system76 system for a variety of reasons, but it doesn't mean pop_os has no reason to exist. On system76 hardware it's probably a very smooth experience. Perception isn't objective so it's never really right or wrong... but I will say you tend to have strong opinions about things you don't necessarily understand very well. You also have to add the extra repository, and either way if the driver isn't present in the installer you might be stuck with a black screen before you even get started. That's increasingly rare because the foss drivers have gotten better, but it does happen at times. Yeah, there's more to these distributions than just taking debian or arch and adding a graphical installer... lots of preinstalled services that are enabled by default, for example. If you use arch, try counting how many systemd services you have enabled since first installation just to get a usable desktop...

I'm against copyright as a concept so I don't really care in that sense. For much the same reason I don't think this is targeting the right thing; make the models be public, not the training data.

I doubt that's the issue, but it can't hurt to try. You can also check to see if there's a newer beta driver available from nvidia.
