I use Xfce and Cinnamon, but I always install Gnome Terminal regardless (you don’t need all of Gnome desktop to use it). The main reason I like Gnome Terminal is that it is very simple, and it lets you save your own terminal themes and switch between them from a context menu. Xfce terminal is nice and simple, but doesn’t have this really handy theme switching feature.

That said, the terminal emulator I used most often is the Emacs built-in terminal emulator (term-mode), because it integrates flawlessly with other Emacs tools. But its rendering and theming isn’t as nice as Gnome terminal, so I only recommend it if you are an Emacs user.

I would go with Guile, because it is built-in to the Guix Package Manager which is a really good general-purpose package manager.

It ticks several of your boxes:

• has a CLI interpreter
• is a general purpose language, Scheme, amd compliant with revisions 5, 6, and 7 of the language standard
• allows writing in a functional style (it is one of the original functional programming languages)
• small disk footprint, but still large enough to be “batteries included”
• decent documentation, especially if you use Emacs
• simple setup: not so much, unless you are using Guix to begin with. The standard distribution ships with lots of pre-built bytecode files, you need an installer script to install everything.

It also has pretty good libraries for system maintenance and reporting:

• File-Tree-Walk
• A simple web server
• XML parsing

both can be installed side by side if you have enough disk space.

Yeah, this is exactly what I do using QEMU and Aarch64 Debian. I suppose I could try the Asahi Linux in QEMU but that actually might be more difficult since I don’t think QEMU can emulate the MacBook hardware, as far as I know. And I can’t do dual boot, I want to be able to switch back and forth between Mac OS and Linux without rebooting anything.

You can try asahi linux on the macbook :)

I could, but I still need Mac OS for work-related things.

I switched to Linux permanently in 2008. Last OS I used before Linux was Mac OS X version 10.4 “Tiger” (if I recall correctly) which is what came with the Macintosh PowerBook that I had bought roughly in the year 2004. I have never used Microsoft software unless someone was paying me to, but at the time, Windows XP was still all the rage even though Microsoft was trying to get everyone to switch to Windows Vista. (Vista got a lot of well-deserved hate too, sort of similar what we see with Windows 11 right now, actually.)

Anyway, I was a die-hard Apple fanboy, but getting more and more into free software and I kept on using Macports/Homebrew to build Linux stuff I found online, but back in those days a lot of apps I wanted to try did not have good support for the Darwin kernel build of GCC which was pretty old compared to what Linux was using at the time. Occasionally a build would fail, and I would try to port the software on my own, with the idea of maybe submitting a package to Macports. But after a while I realized, “if I want to use Linux software, why not just use Linux?”

So I bought a Netbook (Dell Inspiron Mini 10) with Ubuntu pre-installed. I really loved that little computer, I used it for a good 5 years until I needed a more powerful computer. I still have it, actually. I never went back to Apple until this year when I took a new job where they wanted me to use a MacBook Pro. (Again, not using proprietary software unless I am well paid.)

I can say with confidence that Linux is considerably better than Apple’s operating systems. I use Aarch64 Debian 12.5 in a QEMU on that MacBook for most things, only switching over to Mac OS when I really need to.

Never tried it, but everyone I know who has tried it says its the most stable rolling release OS ever. That is pretty cool. Btrfs support is cool too, copy-on-write, deduplication, and whole-disk snapshot and rollback capability, its great for keeping your data safe.

I don't care about rolling releases, I get my stability from Debian, or sometimes Mint. If I want the latest software I’ll install Guix packages or FlatPaks. And I can still use Btrfs on Debian.

I can explain the difference between X11 and Xorg with an analogy to the web and web browsers: X11 is like HTTP, Xorg is like the Chrome browser. X11 is the protocol, Xorg is software that implements that protocol.

X11 is old, it was designed back in the 1980s and includes messages for drawing lines and circles and fonts on the screen. Also, back then there were a lot of “thin clients”, computers that were basically nothing but a browser, since graphics were computationally expensive and could not be done on the client computer, graphics rendering was done server side. There are lots of messages in the protocol for handling screen updates over a computer network.

Nowadays, all personal computers are powerful enough to render their own graphics, and no one needs the display server to draw individual lines or circles on screen. Vector graphics and fonts are done at the application level, not over the network. So these these messages specified in the X11 protocol are hardly ever used. Really, most of X11 (let’s say 90% of it) is not used at all, only the parts where the keyboard and mouse are defined, and how you can allocate memory to buffer a graphic and copy that buffer to the display. But you still need to maintain the Xorg software to handle everything that X11 specifies, and this is just a waste of code, and a waste of time for the code maintainers.

So basically, they decided about 10-15 years ago that since no one uses most of X11, let’s just define a new protocol (called Wayland) that only has the parts of X11 that everyone still uses, and get rid of the 90% of it that no one ever uses. Also, the protocol design takes into account the fact that most modern computers do all of their own rendering rather than calling out to a server to render for them. Also the Wayland protocol design takes into account that a lot of computers have graphics cards for accelerated graphics rendering.

Since the Wayland protocol is much simpler, it is easier for anyone to write their own software which implements the protocol, these software are called “compositors.” Finally, 10 years after some of the first implementations of Wayland, the protocol and compositors are becoming mature enough that they can be used in ordinary consumer PCs.

No, it is because people in the Linux community are usually a bit more tech-savvy than average and are aware that OpenAI/Microsoft is very likely breaking the law in how they collect data for training their AI.

We have seen that companies like OpenAI completely disregard the rights of the people who created this data that they use in their for-profit LLMs (like what they did to Scarlett Johansson), their rights to control whether the code/documentation/artwork is used in for-profit ventures, especially when stealing Creative Commons “Share Alike” licensed documentation, or GPL licensed code which can only be used if the code that reuses it is made public, which OpenAI and Microsoft does not do.

So OpenAI has deliberately conflated LLM technology with general intelligence (AGI) in order to hype their products, and so now their possibly illegal actions are also being associated with all AI. The anger toward AI is not directed at the technology itself, it is directed at companies like OpenAI who have tried to make their shitty brand synonymous with the technology.

And I haven’t even yet mentioned:

• how people are getting fired by companies who are replacing them with AI
• or how it has been used to target civilians in war zones
• or how deep fakes are being used to scam vulnerable people.

The technology could be used for good, especially in the Linux community, but lately there has been a surge of unethical (and sometimes outright criminal) uses of AI by some of the worlds wealthiest companies.

Emacs.

Emacs is an app platform in and of itself, and the vanilla installation comes with dozens of its own apps pre-installed. Like how web apps are all programmed in JavaScript, Emacs apps are all programmed in Lisp. All Emacs apps are scriptable and composable in Lisp. Unlike on the web, Emacs encourages you to script your apps to automate things yourself.

Emacs apps are all text based, so they all work equally well in both the GUI and the terminal.

Emacs comes with the following apps pre-installed:

• a text editor for both prose and computer code
• note taking and organizer called Org-mode (sort of like Obsidian, or Logseq)
• a file browser and batch file renamer called Dired
• a CLI console and terminal emulator
• a terminal multiplexer (sort-of like “Tmux”)
• a process manager (sort-of like “Htop”)
• a simple HTML-only web browser
• man-page and info page browser
• a wrapper around the Grep and Find CLI tools
• a wrapper around SSH called “Tramp”
• e-mail client
• IRC client
• revion control system, including a Git porcelain called “Magit”
• a “diff” tool
• ASCII art drawing program
• keystroke recorder and playback

Some apps that I install into Emacs include:

• “Mastodon.el” Mastodon client
• “Elfeed” RSS feed reader
• “consult” app launcher (sort-of like “Dmenu”)

I wrote a few articles on my blog for people in your situation, who are mostly only familiar with Windows and/or Mac and want to learn Linux more in depth.

“Advice for people who want to learn linux” – This article is kind of an overview of the Linux learning process. The point of this article is to teach you what it is you need to learn about so that you set your own curriculum. Once you understand what a few of the basic things are, you can look up your own tutorials on how to learn each thing.

“How to pick a Linux distro” – This article is for people who are overwhelmed by the number of choices for Linux distro. The bottom line is: don’t over-think it, just pick a mainstream distro like Mint, Ubuntu, or Fedora. There is like a 99.99% chance that each of these will just work as soon as you install it, no weird issues with audio, graphics, WiFi, BlueTooth, or anything else. Also, a lot of the “choices” you see among all those distros are only skin deep – differences in the default theming (i.e. the default “desktop environment”, a concept explained in the “advice” article above). But really they are all using the same basic software packages so there is almost no difference between any of them.

If you have any questions, feel free to ask me here. I can clarify here, and also update my blog posts if you think anything is confusing.

It’s a i3-6006U with just 4.0GiB of RAM.

Emacs is considerably more lightweight than a modern Web browser, or any app based on Electron.js (e.g. VSCode) so a computer with those specs is more than powerful enough to run Emacs. If you use version 29.1 or later, Emacs comes with “libgccgit” which will spend a little time pre-compiling Emacs code to very fast native code.

Emacs used to have a reputation for being slow back in the early 1990s when 32 bit personal computers were just beginning to gain popularity. But nowadays when everyone downloads FlatPak and AppImage and Snap apps which install many hundreds of megabytes of code, Emacs is relatively small and light.

Also, Guile Emacs and Guilemacs are two different projects, right? Because I also happen to come across this, and I’ve been interested in this project as well.

The whole history of Guile and Emacs is here on the Emacs Wiki.

So there are a few projects related to Guile and Emacs. The link you provided me by Ken Raeburn is a fork of older versions of both Guile and Emacs, it seems it has not been worked on in about 20 years, unfortunately.

The project by Robin Templeton is also a little bit out of date, but still somewhat actively developed. You must build it from source from a patched version of (I think?) Emacs 26 or 27, I am not sure which it was. It works by loading libguile (the Guile interpreter/compiler) into Emacs so you can run Scheme code, and it also provides Scheme “foreign function” wrappers to the Emacs C APIs so you can do everything Emacs Lisp does in Scheme by importing the elisp-functions Scheme module. (There is an example of how to use it on the Emacs Wiki.)

I did hear Robin say in a recent Spritely chat that it could be made to work on Emacs 29 with not too much effort, they just haven’t had time to do it.

If you are interested in Scheme, you might also want to check out the Edwin text editor which is built-in to the MIT/GNU Scheme compiler, you launch it from the Scheme REPL with the (edit) function. It is a clone of Emacs 19 (a very old Emacs) written entirely in Scheme, but unfortunately it is a little too old to be useful nowadays, in my opinion. Still, you could learn something by reading the Edwin source code.

Finally there is TeXmacs, which is a full WYSIWYG application with a built-in LaTeX rendering engine designed for writing scientific papers, and it includes the Guile Scheme compiler for writing extensions, although I would not call TeXmacs a general purpose programming text editor the way Emacs is.

Steps are being made toward Guile Emacs integration. The work is mostly being done by Robin Templeton, who (last I heard) works at the Spritely Institute. And as I understand, there are other people pushing on the Guile in Emacs front as well, so you may not have to wait long.

Have you considered trying to setup Kakoune bindings in Emacs? For example like this: https://github.com/jmorag/kakoune.el

Whenever I open the symlink, does the software (player) understand «oh this file seems like a symlink, I should go and open the original file», or it’s a filesystem level stuff and software (player) basically has no idea if a file I’m opening is a symlink or the original movie.mp4?

Others have answered well already, I just will say that symlinks work at the filesystem level, but the operating system is specially programmed to work with them. When a program asks the operating system to open a file at a given path, the OS will automatically “reference” the link, meaning it will detect a symlink and jump to the place where the symlink is pointing.

A program may choose to inspect whether a file is a symlink or not. By default, when a program opens a file, it simply allows the operating system to reference the file path for it.

But some apps that work on directories and files together (like “find”, “tar”, “zip”, or “git”) do need to worry about symlinks, and will check if a path is a symlink before deciding whether to reference it. For example, you can ask the “find” command to list only symlinks without referencing them: find -type l

I don’t understand this guy’s argument at all. First of all, he isn’t using any shell that I know about, he seems to have invented his own, and the command line arguments he uses are specific to his own shell. He doesn’t explain how these command line arguments work in terms of POSIX system calls, so I can’t follow along with what he is actually doing. As far as I can tell, these are security issues with his own software, not with Unix or Linux.

If you are worried about file mutability, you can use ZFS or BTrFS or BCacheFS. All of these filesystems have a snapshot function, so if any changes (e.g. file encryption by ransomware attackers) are made you can reboot and roll back the changes, unless the attackers figure out a way to get root access and delete your snapshots. But if an attacker has gained root access to your computer, that is a much more serious issue and not really in the scope of filesystem security or file mutability.

The snapshot and rollback feature also exists in NixOS and GuixOS, where your operating system kernel and all software installed is part of a snapshot that can be rolled back, if the system becomes unbootable, you can rollback from within the GRUB boot loader. Again, all software installation is managed by a service that runs for you at root level so you never need sudo to install software, and the software you install never effects any other user or the operating system. So the only way to hack this is to gain root access and alter the content of the Guix or Nix “store” database with malicious code, but again, root access is a much bigger issue than what we are talking about.

So yeah, the argument stated in this video makes no sense to me.

I would go with Fedora or Mint, both for their software support and stability. Personally I like Mint over Fedora, I think it has a larger selection of software packages but I could be wrong.

Btrfs is more stable nowadays, I wouldn’t worry about that. And anyway you can choose XFS or Ext4 during installation while setting up your disk partitions.

If you are worried about a particular software package being too old, try installing FlatPaks instead, or use the Nix or Guix package managers which can co-exist easily with any other package manager.

@joeldebruijn@lemmy.ml the /run/user/1000 directory is an in-memory file system of a fairly small size. The operating system creates it for you to store certain things that are for your user account only. The permission settings on this directory forbid any other user on the system (except for “root”) to see what is inside. This makes it safe to store secret information that only you should know.

One typical example of something stored in this directory would be your plain text (unencrypted) password database if you use a password manager. No other user but you (and “root”) can see it, and it is in-memory only so it is not accidentally copied to your persistent memory (HDD or SSD disk drive) where it might be removed and read by hackers if someone steals your computer from you. At the same time, any program running on the system that was launched by you and only you has access to your passwords so you don’t need to remember passwords for everything. (Actually it is a socket to a server containing your unencrypted password database in memory, it is probably not actually a file in that directory.)

Other things that go in this /run/user/1000 directory are socket connections to the desktop bus (allows for things like copy-and-paste or drag-and-drop to work between programs), socket connections to your audio mixer (allows you do things like to listen to music and do video chat at the same time), and a record of what external media devices you have connected to the computer which you are using via GVFS, and so on.

Also, the number 1000 is your user ID number assigned to you by the operating system. If you create other accounts, they will have ID 1001, 1002, and so on, and each of them will have a directory with that number created in the /run/user directory for them when they login.

Someone with more expertise can correct me if I am wrong, but the last I heard about this, I heard that cluster computing was obsoleted by modern IaaS and cloud computing technology.

For example, the Xen project provides Unikernels as part of their Xen Cloud product. The unikernel is (as I understand it) basically a tiny guest operating system that statically links to a programming language runtime or virtual machine. So the Xen guest boots up a single executable program composed of the programming language runtime environment (like the Java virtual machine) statically linked to the unikernel, and then runs whatever high-level programming language that the virtual machine supports, like Java, C#, Python, Erlang, what have you.

The reason for this is if you skip running Linux altogether, even a tiny Linux build like Alpine, and just boot directly into the virtual machine process, this tends to be a lot more memory efficient, and so you can fit more processes into the memory of a single physical compute node. Microsoft Azure does something similar (I think).

To use it, basically you write a program a service in a programming language that runs on a VM and build it to run on a Xen unikernel. When you run the server, Xen allocates the computing resources for it and launches the executable program directly on the VM without an operating system, so the VM is, in effect, the operating system.

Linux does not support ZFS as well as operating systems like OpenBSD or OpenIndiana, but I do use it on my Ubuntu box for my backup array. It is not the best setup: RAID-Z over USB is not at all guaranteed to keep your data safe, but it was the most economical thing I was able to build myself, and it gets the job done well enough with regular scrubbing to give me piece of mind about at least having one other reliable copy of my data. And I can write files to it quickly, and take snapshots of the state of the filesystem if need be.

I used to use Btrfs on my laptop and it worked just fine, but I did have trouble once when I ran out of disk space. A Btrfs filesystem puts itself into read-only mode when that happens, and that makes it tough to delete files to free-up space. There is a magic incantation that can restore read-write functionality, but I never learned what it was, I just decided to stop using it because Btrfs is pretty clearly not for home PC use. Freezing the filesystem in read-only mode makes sense in a data-center scenario, but not for a home user who might want to try to erase data so one can keep using it normally. I might consider using Btrfs in place of ZFS on a file server, though ZFS does seem to provide more features and seems to be somewhat better tested and hardened.

There is also BCacheFS now as an alternative to Btrfs, but it is still fairly new, and not widely supported by default installations. I don’t know how stable it is or how well it compares to Btrfs, but I thought I would mention it.

I keep a Gnome Shell instance always running with a Screen session. However, what I actually use to run CLI commands is Emacs Shell, built-in to Emacs.

Emacs Shell has most of the bells and whistles you get from things like Fish shell. So I like to use Dash, a minimal POSIX shell that is much lighter weight than Bash, Zsh, or Fish. Dash provides no features – no tab completion, no history, no line editing – and I have Emacs add all of those features on top of Dash for me. It is amazing what a good, scriptable terminal emulator can accomplish.

Emacs Shell can be scripted using the same scripting language it uses to script the editor, file browser, window manager, and everything else. So you can script the shell to search for regular expressions and make things clickable with the mouse, or only display portions of output, creating simple interactive views around shell commands. You can bind certain click buttons or keystrokes in the editor or file manager to run shell commands in new windows. You can script the shell with “expect”-like behavior (automatically input responses to certain prompts). You can capture and collate the output of multiple commands running in parallel.

And no, they don’t speak to one another / find one another or are able to follow / like / reply to one another as one is told the Fediverse works.

This is true, it is a problem, but maybe not as big a problem as you think.

Kbin combines the data model of both Lemmy and Mastodon so Kbin can interact with both of them perfectly. Mastodon can interact in a limited way with Lemmy. Frendica and Pixelfed also work fairly well with Mastodon, so Kbin should be able to interact with both of those as well, although I have never tried. PeerTube is probably the least compatible, although I can upvote and post comments on PeerTube videos using my Mastodon account, and follow PeerTube accounts on Mastodon. But I can’t create new PeerTube posts on Mastodon. I hope in time all of these different app services will be able to interact with each other more.

The most difficult thing right now is moderation tools. Right now, banning instances is very coarse, and it also deletes the entire social graph between instances, so people who were following each other lose their connections with each other, even after the ban is removed.

There are people working on solving that problem right now, but it might be a little while before the changes are spread throughout the network.

What I would like most is if I can create one ActivityPub account and use it on every ActivityPub service. This for me would be a perfect solution, because then I could use any app using a single account. I would also like to see it possible to ban instances temporarily without losing social connectivity, and I would like to see better moderation tools for individual user accounts being banned by an instance.
