Alt TextA screenshot of a file manager preview window for my ~/.cache folder, which takes up 164.3 GiB and has 246,049 files and 15,126 folders. The folder was first created about 1.75 years ago with my system
FYI, Windows doesn’t have any feature either to automatically clear all of it’s temp folders (%TMP%, C:\Windows\Temp, C:\Windows\Panther), plus several other folders where orphaned files are often leftover, such as C:\Windows\Installer, C:\Windows\CSC, and various folders and cache files in your AppData\Local etc, to name a few off the top of my head.
I used to be a Windows sysadmin for a long time, and let me tell you, HDDs becoming completely full due to cache/temp files is very much a problem in Windows.
If you’re talking about the Storage Sense feature - it sucks. It only clears a handful of well-known locations, but it doesn’t touch any of the orphaned content in C:\Windows\Installer, or the CSC or the old Panther folders from upgrades, not to mention several other files and folders in AppData. As I’ve said before, I’ve been a Windows sysadmin (until last year infact) managing over 20,000 devices, we’ve had Storage Sense on, but it’s been mostly useless - to the point that I ended up writing own cleanup script and set it to run before we pushed out a new Windows feature update, because otherwise we’d get several devices which failed to update due to the disk being full.
Similar experiences here. I remember waiting for the free CDs bundles with monthly magzines, and add then I’d the CD as a mirror in my repos to update my packages lol
That link is for kernel 5.14, so I’d say those results are pretty much invalid for most users (unless you’re actually on it, or the 5.15 LTS kernel). There have been a ton of improvements in every filesystem since then, with pretty much every single kernel release.
A more relevant test would be this one - although it talks about bcachefs, other filesystems are also included in it. As you can see, F2FS is no longer the fastest - bcachefs and XFS beat it in several tests, and even btrfs beats it in some tests. F2FS only wins in the Dbench and CockroachDB benchmarks.
Not OP, but yes, that’s pretty much how it works. (ZFS scrubs do not defrgment data however).
Fragmentation isn’t really a problem for several reasons.
Some (most?) COW filesystems have mechanisms to mitigate fragmentation. ZFS, for instance, uses a special allocation strategy to minimize fragmentation and can reallocate data during certain operations like resilvering or rebalancing.
ZFS doesn’t even have a traditional defrag command. Because of its design and the way it handles file storage, a typical defrag process is not applicable or even necessary in the same way it is with other traditional filesystems
Btrfs too handles chunk allocation effeciently and generally doesn’t require defragmentation, and although it does have a defrag command, it’s almost never used by anyone, unless you have a special reason to (eg: maybe you have a program that is reading raw sectors of a file, and needs the data to be contiguous).
Fragmentation is only really an issue for spinning disks, however, that is no longer a concern for most spinning disk users because:
Most home users who still have spinning disks use it for archival/long term storage/media that rarely changes (eg: photos, movies, other infrequently accessed data), so fragmentation rarely occurs here and even if it does, it’s not a concern.
Power users typically have a DAS or NAS setup where spinning disks are in a RAID config with striping, so the spread of data across multiple sectors actually has an advantage for averaging out read times (so no file is completely stuck in the slow regions of a disk), but also, any performance loss is also generally negated because a single file can typically be read from two or more drives simultaneously, depending on the redundancy config.
Enterprise users also almost always use a RAID (or similar) setup, so the same as above applies. They also use filesystems like ZFS which employs heavy caching mechanisms, typically backed by SSDs/NVMes, so again, fragmentation isn’t really an issue.
Not quite. Bcachefs can be used on any drive, but it shines the best when you have a fast + slow drive in your PC (eg NVMe + HDD), so the faster drive can be used as a cache drive to store frequently accessed data.
Initial benchmarks show better performance than btrfs (at least for some workloads), but more importanty, I like that it offers tiered/cache storage - so you can use a fast and small drive (NVMe) to speed up a slow and bigger drive (HDD). You can do that with ZFS as well of course, but it doesn’t have the massive RAM requirements. Also it’s much more easier to set up and configure in comparison.
Now i’ve been considering moving to linux. I don’t have much of a history using a computer and find it tougher to use than my phone. But I also really appreciate the foss movement. I’ve currently got an old laptop running windows 11 I think and it would prolly speed up with linux too. But I’m afraid I’d fuck smth up...
Are you sure about that? Most countries around the world have a Linux user group of some sort. Find out what your local group is called, get in touch and I’m sure you’ll be able to find someone who’ll be more than happy to help.
Curiosity. I was a curious tweenager, and I was already a bit of a geek at the time. I read about Linux in computer magazines at the time, and decided to give one of the free CDs a try - with RedHat 5.2 on it. To be honest, wasn’t really impressed with it. I especially disliked having to recompile the kernel, which took ages on those Pentium 3s. But it got me exploring other operating systems, and I found QNX, BeOS and NetBSD. I was really impressed with with QNX and BeOS in particular - Linux felt quite clunky and amateurish in comparison. I especially liked the multimedia performance of BeOS, and the lightweightedness, polish and desktop responsiveness of QNX, which featured a real-time microkernel. QNX felt lightyears ahead of it’s competition at the time. My first run into it was a free 1.44MB demo floppy that the company mailed me directly, complete with a full developer manual (which was completely wasted on me as a tween, but I still appreciated it and tried to comprehend bits and pieces). I was already into making custom bootable floppy disks at the time, so I was extremely impressed that they managed to fit in a full fledged GUI desktop, complete with a browser that supported Javascript (along with network drivers and a modem dialer) - all on a 1.44MB floppy disk! Till date I’ve no idea how they managed that. Even the tiniest of Linux WMs are massive in comparison and look fugly (twm), but QNX’s Photon microGUI somehow managed to make it good looking and functional. Maybe it was all coded in Assembly, I don’t know, but it was, and still remains, very impressive nonetheless.
I digress, but all this started getting me into exploring POSIX systems and distro/OS hopping. It was only when I experienced SuSE that I fell in love with Linux. Finally, I had a polished Linux desktop, with a full-featured settings/control panel (YaST) that made it easy to use even for a tween like me. And that’s when I switched to Linux as my main-ish OS, with Windows relegated to gaming duties. However, I didn’t fully get rid of Windows until Windows 7. I was actually impressed with the Windows 7 beta releases and was prepared to buy it at release, but… I wasn’t expecting that price tag. I was hoping I’d get a student discount, but it wasn’t applicable where I lived (or there was some catch, I don’t remember exactly). In any case, I couldn’t afford it, and I was really disappointed and angry at Microsoft that they were charging so much for it here, compared to the US pricing. And so, on the release day of Windows 7, I formatted my drive and switched to Linux full time, and never looked back.
I’d wager that it’s your scheduler. Prior to the latest kernel release (v6.6), Linux used the CFS scheduler which is outdated and not really optimal for desktop usage. As a result, many third-party alternate schedulers were developed to fix this issue, with the most recent popular ones being the System76 scheduler (used in Pop!_OS), and BORE (used in CachyOS). But this issue has been solved officially now, with the EEVDF scheduler (earliest eligible virtual deadline first scheduling), which has finally replaced CFS.
So if you’re not on 6.6, upgrade to it, or use the System76 scheduler. Also switch to Wayland if you haven’t already and you’ll notice your Linux desktop just as smooth, if not smoother, than Windows.
I have an M1 MacBook Air and a Thinkpad Z13 G1 (running Bazzite KDE with kernel 6.6.3 + System76 scheduler), and comparing the touchpad gestures and window animations side-by-side - especially the gestures and animation to switch workspaces - it’s just as smooth as macOS (at least to my eyes), and that’s quite the feat given that macOS has been the king of smooth animations and responsiveness for a long time.
Anti-cheat support in general has been a thing in Linux since the past couple of years, thanks to the efforts of Valve and the Steam Deck’s popularity. But not every game works though, depending on the anti-cheat system used and it’s implementation, some effort from the dev might be needed to make it compatible. areweanticheatyet.com tracks the current status of these games, and www.protondb.com is also a good reference in general to check Linux game compatibility.
But if you don’t have any complex software requirements besides gaming and the usual desktop apps, then Bazzite is a much, much better option. It gets updates much more earlier than Nobara (which is still stuck on Fedora 38), and is much more stable (immutable OS) and more gaming optimised. You can even boot directly into “gaming mode” for a Steam Deck-like experience, with all the same (+more) optimizations that you’d get from the Deck.
On a random note, as a fellow relic of a bygone era… remember back when Windows used to be customizable, when you could modify just about any file, change themes without a hack, without things like Trusted Installer/Defender getting in your way, or even completely replace your explorer.exe with a different shell like BlackBox? I miss those days.
This is Linux (Debian) running locally on my Android phone (Galaxy Fold 4), with a Win95 theme. I think it’s pretty awesome that Linux still lets you do stuff like this, whilst still maintain a good security posture. And letting me relive the memories of the good ol’ days. :)
At least it’s a bit more full-featured than Fedora 39, where they just updated to Gnome 45 and called it a day, and KDE users didn’t even get anything new at all.
I’ve been a software engineer for 10 years now but want to work with Linux more in a professional setting (not to mention the number of layoffs in the the dev industry has me thinking a backup plan might be a good idea). I have been using Linux exclusively on my personal machine for about 15 years now so I’m not too worried...
Sorry, I guess I meant Docker Desktop, and some of their other proprietary business/enterprise tools (like Docker Scout) that companies have started to use, the stuff that requires a paid subscription. The Docker engine itself remains opensource of course, but a lot of their stuff that’s targeted at enterprises isn’t. These days when companies say “Docker” they don’t mean just the engine, they’re referring to the entire ecosystem.
Also, I have a problem with Docker itself. My main issue is that, on Linux, native container tech like Podman/LXD work, perform and integrate better (at least, from my limited experience), but the industry prefers Docker (no surprises there). As a Linux guy, naturally I want to use the best tool for Linux, not what’s cross-platform (when I don’t care about other platforms). But I can understand why companies would prefer Docker.

A GPU is used for a lot more than just gaming these days. It’s used to render videos, accelerate normal 2D programs (like some terminal emulators), accelerate some websites/webapps (those which use WebGL for eg); also modern DEs like Gnome and KDE also make use of it very heavily, for instance for animations and window transitions. Those smooth animations that you see when you activate the workspace switcher or window overview? That’s your GPU at work there. Are your animations jittery/laggy? That means your setup is less than ideal. Of course, you could ignore all that and just go for a simple DE like XFCE or Mate which is fully CPU-driven, but then the issue of video acceleration still remains (unless you don’t plan on watching HD videos).
Without the right drivers (typically NOT nouveau, unless you’re on a very old card), you may find your overall experience less than ideal. As you can see in their official feature matrix , only the NV40 series card fully supports video acceleration - these are cards which were launched between 2004-2006 - that’s practically ancient in computer terms and I highly doubt your PC uses one of those. Now recent-ish cards do support video acceleration, but you’ll need to extract the firmware blobs from the proprietary drivers (which can be a PITA on normal Debian as it’s a manual process), plus, even after that, the drivers won’t support some features that may be required by normal programs, as you can see from the matrix.
The natural solution of course would be to install the proprietary nVidia drivers, but you do NOT want to do that (unless you’re a desperate gamer) as there’s a high possibility of running into issues like not being about to use Wayland properly, or breaking your system when you update it - just Google “Linux update black screen nVidia” and you’ll see what I mean.
You’ll be avoiding a lot of headache if you just went with AMD; or even just onboard graphics like Intel iGPUs (if your CPU has it) would be a much better option - because in either case, you’ll be using fully capable and stable opensource drivers and you won’t face any issues with that.
Autotype is already solved - ydotool, wtype and dotool exists (and possibly others as well).
Screen magnification is already present in KDE (Meta + +, Meta + - to zoom in/out). There’s also a magnifier tool (KMag). There may be similar functionalities in other DEs.
My issue is the lack of an overall GUI automation tool, ie, like AutoHotkey. X11 had PyAutoGUI, but there’s no such AIO equivalent for Wayland yet, and the PyAutoGUI devs don’t seem to be interested in Wayland support - it’s neither on their road map, nor have they even answered any Wayland questions on their Github page, which is disappointing. But this isn’t Wayland’s fault, when other tools have shown that automating the GUI is possible, we just need someone to put together a complete package like PyAutoGUI / AHK.
I installed endeavourOS 2 days ago and then, the next day, there was a newnrelease of endeavourOS. It’s supposed to have better encryption. Is it possible to upgrade encryption on Linux? An unrelated question: is it possible to change the password of an encrypted partition? I’m a beginner, so please explain your magical...
If you’re a beginner then don’t worry about the encryption. Unless you’re hiding from some three-letter agency or being targeted by hackers or something, LUKS1 encryption is more than good enough (for an average home user).
But just so you’re aware, whilst it’s trivial to convert to LUKS2 using cryptsetup convert, you’ll need to first switch your bootloader to systemd-boot from GRUB, and that may not be a trivial process as there’re multiple variables involved - is your ESP big enough, have you mounted your ESP to /boot, whether you’re using secure boot or not, whether you’re dual-booting or not etc. Plus you’ll also need to manually create a bootloader config file that’s specific to your system, and maybe even add a line to load a CPU microcode file if you’re on Intel… there’s a lot of things to consider here.
Honestly, I wouldn’t recommend EndeavorOS to you as a newbie, because it’s basically Arch, but by making the installation easy, you’re skipping all the knowledge you’d get of your system and how it works. And when it comes to situations like you’re in, you reach a roadblock because you took the easy path.
If you’re really interested in Arch then I’d recommend wiping your system and install Arch manually, the Arch way.
