If you run a #Linux program in #strace, usually the start of the log shows it trying to load a ton of shared libraries, and for each one, trying the same file name in all your LD_LIBRARY_PATH directories until it finds it. So you mostly see file-open operations _failing_, with ENOENT.

To a novice strace reader, it looks as if something has already gone horribly wrong! But it hasn't – this is all normal, and as expected. Each of those ENOENT is technically "an error", but not a _bad_ error, because ld.so just moves on to the next in its big list of things to try, and one works in the end.

Errors happen _all the time_ in the guts of a computer system, and most of them are not even interesting – just business as usual. The event an end user thinks of as "an error" is the case where the program _doesn't_ have a fallback plan. Those are often outnumbered by the cases where it does!

I have been using KDE for a while, while I like many features I am looking for suggestions to the default email client:

Kmail - completely unusable for me and the only one which could maybe be integrated with kontacts, it could not receive mails from IMAP or pop or would receive only sometimes

Geary - good but too minimal, I need at least some kind of contact list and mailing lists feature, maybe this integrates with gnome contacts? I couldn’t find anything in settings

When I bought the XEphem ephemeris and planetarium program in the 1990s it was the first astronomy software I used on Linux.

Now available as open source, it is still as advanced as back in the day with features few similar programs have. With its Motif user interface frozen in time and now turned retro, here is XEphem on my Linux Mint box where it still builds and runs fine. Almost permacomputing.

Screenshot of the desktop of a Linux Mint Cinnamon PC. Aside from a horizontal taskbar at the bottom, most of the desktop is taken by 8 windows of an astronomy program. The program's user interface is based on the Motif toolkit and the windows show ephemeris, star charts, planetary globes, and other visualizations of astronomical data.

would the performance be huge and be very awesome?? if i had a computer with the latest amd ryzen chip and with 4tb of ssd and 16gb of ram and installed lubuntu on it, what would happen?

has anyone ever tried this??

So I installed KDE Plama on my Arch Linux machine (paru -S plasma) but it came with flatpak which I don’t use so I removed it (paru -Rns flatpak-kcm), now after reboot the system become so unresponsive and some programs didn’t even start (I install all of my programs from the AUR) I had to hard shutoff every time it stop responding, So I’m wonder if flatpak is essential to Plasma functionally?

I’m trying, and struggling a little bit with getting the three items in the title setup the way that I want.

Running Arch.

I would like to run Radarr, Sonarr and SABnzbd all under the same user/group. My reasoning is that I (am just being overly particular) want any of the files created by those services to fall under the same owner/group. This is easy enough to accomplish by running systemctl edit service.service and adding the appropriate lines in the configuration for each one and saving it so the services run using the specified user/group.

The issue that I’m having is that the correlating folders in /var/lib/ have the ownership of the original users. I can manually change that ownership to the user/group I want but if I reboot the computer the SABnzbd folder ownership reverts back to default (the other two were doing the same thing but suddenly stopped and I’m not 100% sure why) or if the services get updated, the folders will also revert back to their default user/group.

Is there a way for me to enforce the ownership of those folders to the user/group that I have set to run the services regardless of them getting updated or the machine rebooting?

#Syd is a rock-solid application #kernel to sandbox applications on Linux>=5.19. Syd is similar to Bubblewrap, Firejail, GVisor, and minijail. As an application kernel it implements a subset of the Linux kernel interface in user space, intercepting system calls to provide strong isolation without the overhead of full virtualization. Syd is secure by default, and intends to provide a simple interface over various intricate #Linux #sandboxing mechanisms such as LandLock, Namespaces, Ptrace, and Seccomp-{BPF,Notify} https://gitlab.exherbo.org/sydbox/sydbox

gVisor implements the #Linux API: by intercepting all sandboxed application system calls to the kernel, it protects the host from the application.

deshuffle is a terminal word puzzle game, written in Bash.

The simple aim is to put all the given letters in order to find the shuffled word against the clock. The time available after a number of words also reduces, so the game gets harder as it goes.

There is not only one solution to every puzzle. If the user find a word with the same letters, the solution will be accepted.

By default, the adjusted definitions of the words appear in the end of each round.

The game ends when the user fails to find the word in time, or fails to create an acceptable solution altogether.

If the score is among the 10 best scores achieved, it makes it in the Top Ten Highscores.

This game was inspired by https://wordnerd.co/23words/.

Background: I am a lifelong Windows user who is planning to move to Linux in October, once Microsoft drops support for Windows 10. I use a particularly bad laptop (Intel Celeron N3060, 4 GB DDR3 RAM, 64 GB eMMC storage).

I do have some degree of terminal experience in Windows, but I would not count on it. If there are defaults that are sensible enough, I’d appreciate it. I can also configure through mouse-based text editors, as long as there is reliable, concise documentation on that app.

So, here’s what I want in a distro and desktop environment:

• Easy to install, maintain (graphical installation and, preferably, package management too + auto-updating for non-critical applications)
• Lightwight and snappy (around 800 MB idle RAM usage, 10-16 GB storage usage in a base install)
• Secure (using Wayland, granular GUI-based permission control)

I have narrowed down the distributions and desktop environments that seem promisimg, but want y’all’s opinions on them.

Distributions:

• Linux Mint: Easy to install, not prone to randomly break (problems: high OOTB storage usage, RAM consumption seems a little too high, kind of outdated packages, not on Wayland yet)
• Fedora: Secure, the main DEs use Wayland (problems: similar to above except for the outdated packages; also hard to install and maintain, from what I have heard)
• antiX Linux (problems: outdated packages, too barebones)

Desktop Environments:

• XFCE: Lightweight, fast, seems like it’d work how I want (problems: not on Wayland yet, that’s it)
• labwc + other Wayland stuff: Lightweight, fast, secure (problems: likely harder to install, especially since I have no Linux terminal experience, cannot configure through a GUI)

In advance, I thank you all for helping me!

I appreciate any help, especially in things like:

• Neofetch screenshots, to showcase idle RAM usage on some DEs
• Experiences with some distributions

My OpenSUSE Tumbleweed is wonky since I last did a dist-upgrade with about 4000 packages. Midway through it errord out with an error that indicated that the filesystem was full althou df showed plenty of free space.

BTRFS seemed to be the culprit. Removing snapshots let me continue the upgrade until it errored out again. Rinse and repeat until it was done.

But now the BTRFS seems to be almost full and I cannot update anymore.

How do I enable proper word formatting in neovim?

I just found this out recently. So this isn’t actually Nautilus itself but it’s the file previewer (Gnome Sushi) that comes with it. If you select a file and press the spacebar, it will automatically preview the file if it supported. If the file is an audio file, it will automatically fetch album art from the web, and if the file is an HTML file, it can make third-party requests. IMHO this is a huge privacy issue. For example if you were browsing the web using Tor Browser and saved a page to view offline, and then later accidentally opened it using the file previewer, it will make requests through the clearnet, exposing your IP.

This is an open issue and I don’t expect it to be fixed anytime soon, so the easiest solution is to simply uninstall Gnome Sushi (on Fedora, it is the sushi package).

Just a recomendation, as the theme is quite beautiful.

I have some desktops (the tower kind) lying around and I’m wondering if there’s a way that I can connect them all to one display and combine their computational power or at least make them all accessible in one place. I want to get into server hosting but only have one monitor. They’re currently running LMDE.

Any ideas?

🚨 #WintermuteBBS - that's my second, #Linux based #BBS running the #MBSEBBS software - is now #back #online !

I've updated MBSE BBS to the latest version 1.1.0 (this is a pre-release but I don't mind) and purged quite a bunch of inactive users.

There will be smaller updates and changes throughout the next weeks, as some of the #rss #feeds no longer work and will either be updated or removed (most likely the latter) .

With the code to support plain #ASCII terminals being rewitten in this new release, I will try to rework some of the ASCII screens - but this is may take some time.

When you manage to install Linux on everything you own. 😆

#WintermuteBBS - that's my second, #Linux based #MBSEBBS - is currently #offline as I need to do some urgent #maintenance and #updates.

I will also purge all accounts that have been inactive for more than 24 months (those are quite a bunch) and keep that policy for the future.

I will notify you once the system is up again.

This is not a troll post. I’m genuinely confused as to why SELinux gets so much of hate. I have to say, I feel that it’s a fairly robust system. The times when I had issues with it, I created a custom policy in the relevant directory and things were fixed. Maybe a couple of modules here and there at the most. It took me about 15 minutes max to figure out what permissions were being blocked and copy the commands from. Red Hat’s guide.

So yeah, why do we hate SELinux?

i made the icons bigger now so that no one loses sight of them and they are just one click away!! any icon, and it’s divided between two panels, reminiscent of gnome2, classic gnome2.

and it is in light mode, if i made a distro and added xfce, i would make so many changes!! like light mode only (for elderly and visually impaired and people who like reading a lot, that is me yea) and big icons so that everyone knows what’s going on.

Let’s say I want to build a GPS module for my car, which is only a GPS, doesn’t hold anything else. Or a recipe tablet for my kitchen which only hold a recipe app.

Is this kind of purposes common? What would be the best way to do this kind of stuff? How do I choose the hardware? How do I “lockdown” certain aspects I don’t need about software?

These kind of devices could be convenient because, by only holding what’s needed, they would use less resources, they would be completely distraction free and they would be suitable to be used by non tech savy user which would need to use only one or two programs without messing with the system in any way.

I know KDE ha some kind of multi app kiosk settings, GNOME also can achieve something similar tho it’s more confusing… There are some kiosk distros which only give you a browser. But I don’t see anything that can be set up, customized, and locked like that.

But would that be the best way of achieving something like that? I mean to use a GPS I don’t need a terminal, nor video codecs, nor a browser… Maybe I can add the possibility to send Osmand google maps links… Or I can decide to make it hold Spotify too to make it a radio as well… But a full distro would be wasted!

But how do I prevent every other use except the intended ones? Is there an easy way to achieve a “one purpose device” using Linux? Should I simply use whichever distro I like and uninstall everything which is not needed (I see use case for arch)?

I feel like we have the total freedom of Linux distros on one side, and companies using managed devices on the other by setting complicated policies, but I don’t know any options in between!

Maybe the focus here is the desktop environment more than distros! Are there desktop environment purposed to give the user a set of limited apps, or a single app (which isn’t only a browser)?

Silly practice 😜 but I am inclined to ...
