I'm just some kind of nerd: software developer, big fan of functional programming, especially Haskell and Scheme. I also love old Macintosh computers. Haskell programming since 2007, Linux user since 2008, Emacs user since 2018. Currently working as an app developer at a small machine learning consultancy. You could call me a "full stack" engineer, but server-side is where I am really in my element.

about every two years I ditch my init.el and build back up from scratch, and every time it feels great. I'm finally breaking off from org-roam which, for all the good its done me, has become a thorn in my side due to the centralized store. about to give a try, which I've been interested in for a while now.

@dekkzz76 Hyperbole creates a set of rules for identifying links which are only activated when you press the hyperlink activate key chord "M-RET" key. Of course, Emacs can already assign hyperlink properties to arbitrary text, but Hyperbole provides two advantages over an ordinary hyperlink:

  1. Since the Hyperlink rules are only applied on the "activate" key chord, you can apply very sophisticated rules to just the text under the cursor without having to parse the whole buffer and assign hyperlink properties to text, which would be very slow. This makes the Hyperbole hyperlinking rules much more versatile.
  2. The key chord is enabled as a global minor mode, so the hyperlink rules work in any buffer, regardless of what mode the buffer may be in. It is basically a markdown for links that can be included anywhere. The advantage of markdown is of course that it is human-readable, even if your editor does not recognize it as markdown. So you can include Hyperbole links in the comments of source code, in e-mail messages, or as the output of shell scripts, and the hyperlinks all just work (as long as you are in Emacs).

> "If I'm understanding links/buttons correctly, it would enable me to create commands from text (and at any point I want to do so)?"

@zyd yes, there are two button markups for calling arbitrary Emacs Lisp commands:

  • Curly bracket-delimited key chords will run whatever command is bound to those key chords, for example {C-20 M-g M-g} will call "goto-line" with 20 as an argument. (Make sure the cursor is placed somewhere within the brackets, not on or before the brackets).

  • Angle bracket notation executes arbitrary Emacs Lisp code within the brackets. (It is safe because you can see what code will be executed.) For example:

    <mark-whole-buffer>

    <eval (save-excursion (goto-char (point-max)) (insert "Hello, world!n"))>

And of course you can define your own functions and commands with descriptive names:

<my/git-fetch-and-pull-here>

@louis this would be my solution. Although I would go with Guile Scheme instead of Common Lisp, because of Guix packaging. And I would make a server too, and make it more like Kbin where you can do both Mastodon and Lemmy like posing.

In Nixpkgs, the ‘shepherd’ package is not what I’d expect.

ramin_hal9001,
@ramin_hal9001@emacs.ch avatar

@civodul "shepherd" in NixOS is a little dissapointing:

"A utility for applying code changes across many repositories"

@Mehrad that's nice, if there were a copyright battle, GNU Shepherd would win.

ramin_hal9001,
@ramin_hal9001@emacs.ch avatar

@Mehrad @civodul it is true, Guix will need a lot more engineering resources (full-time, paid software developers) before it could become useful. It especially lacks hardware support unless you go out of your way to setup non-free software package channels.

For the most part, if you stick to only using the main package channels, and don't do anything fancy for developing your own apps like changing package dependencies or build options, everything just works. This at least gives you access to instant roll-backs, and things like GNU Shepherd.

I prefer to use Guix as a package manager, in particular, I will use Guix as an alternative to FlatPak, Snap, and AppImage. It co-exists perfectly with any Linux distro's native package manager. So I let my Linux distro handle my operating system and desktop environment, and I install my favorite apps with Guix.

ramin_hal9001,
@ramin_hal9001@emacs.ch avatar

@Mehrad @civodul I think if you go to the Guix hompage, there is a "Help" menu, and there are links there to a Guix reference card, the Guix cookbook, and the Guix manual. So this serves as a single entry point, does it not?

Part of the problem is that Guix can be used as an Linux distro and a package manager, and the package manager is highly configurable with various channels. So your "entry point" to Guix might be different from other people, depending on how you want to use it. I think the Guix homepage does a pretty good job of providing resources for general purpose use cases. It seems to me that if you are using the HPC channel, you are not in the group of people who use Guix for general purposes.

> "For example as one of the most confusing parts: there is https://packages.guix.gnu.org/ and https://hpc.guix.info/browse to search for packages, (why?)"

The reason why is because there are multiple channels for packages. I recommend you use Guix command line tools to search for packages, rather than using the websites, because the Guix command line will search all the channels that you have access to, rather than you needing to know which channel provides which package and searching the channel website.

guix package --search='name-of-thing*'

> "Guix extremely relies on info pages. But that is not well known to 99.9% of world population."

For what it's worth, I really love the Info manual pages, it is very easy to find all the information I am looking for in this documentation, as long as you use Emacs (which I do) or the stand-alone "info" CLI utility. All you need to do is use the search features: index search (press "i" and type your query with tab completion) and menu search (type "m" and type your query with tab completion). The "index" is the index of all keywords in the manual, it is good to use if you do not yet know what you are looking for. The "menu" is a list of all documentation subsection titles, it is good to use if you already know what you are looking for.

Until the kids started using the Xbox again I had no idea how many games these days are networked and "multiplayer" except that the presence of other players seems to add very little value to the game, because even though the game might show them, you don't actually interact with them in any way. The networked nature of the game doesn't change the gameplay at all except for leaderboards or whatever. It's like in The Sims where other Sims from the same install (perhaps belonging to other players) would occasionally interact with yours.

Kids who grow up loving these games aren't going to be able to play them later, because many of them won't work at all when they're not networked even though being networked didn't really matter to the game, all in the name of "engagement" or encouraging in-game purchases or whatever. And that's before even considering DRM.

@rml "git grep" wont work as-is because it is encoded in the source code with ROT-13, so you would have to grep for the ROT-13 encoded string for "COMMUNISM" in order to find it. They aren't stupid enough to leave a subliminal clue like that as plain text right there in the source code.

This epsidode of "The Computer Chronicles" mentions expert systems and Lisp systems.

Also, I am pretty bitter that Python became the language of choice for statisticians and therefore modern machine learning and neural networks, when back in the 70s and 80s everyone thought Lisp machines were computers that was going become sentient. Lisp is superior in quality to Python in almost every way.

@fedwards9965 @ozzy @blogdiva damn, ain't that the truth. Looking at the centrist comments in this thread is proof positive of that. Centrists love to think of themselves as so much more reasonable than the Trump right, but then lose their shit when anyone criticizes their president, casting around accusations of "ruining our democracy".

So the centrists defend thir own brand of fascism while calling it "democracy", and claim to be "anti-fascist." They oppose the fascism of Trump simply because Trump isn't the brand of fascism they prefer, and to that end defend a president who... (checks notes) assists in committing genocide of simitic/arab people in Gaza, but that's OK because Trump would do the same and worse. Yeah. "Reasonable" people, not "far left." Well done guys.

I'll vote Democrat because, as @blogdiva has said before, it is harm reduction, and I will still criticize Biden and the Democrats for every single last amoral thing that they do office, because that is the moral thing to do.

I actually want to run or something with Linux (Guix OS) on the host machine, since most of the software I rely on is for Linux. I have tried but it has never been a good user experience for me.

I am leaning toward Mac OS X just because it seems to require less memory than Windows but both Mac and Windows ask for a minimum of 4 GB, and I want the host OS to take as little memory as possible and leave as much as possible for the guest Linux OS. Also, its a system with , and in my experience the native versions of most Linux software work pretty well on Mac OS X.

@ramin_hal9001@emacs.ch avatar

> "I've worked with regexp libraries that took () as literal and () as grouping operators (e.g. in sed and nvi)"

@RogerBW @louis this is the correct answer in the case of Emacs. Here "(...)" are grouping operators, do not use backslashes if you want to match literal paren characters. Another good way to ensure you mean literal parens is to write "[(][)]", i.e. place them in character sets.

Confusingly, Emacs treats "+" as "match one or more" and "+" a literal character, which is the opposite of how Sed and "grep -e" does it. Apart from that, the escape codes in Emacs work pretty much the same as Sed or "grep -e".

    Given the recent changes planned to be coming to coinciding with a rare lull in my daily work, I finally decided to go through with the effort to switch my browser over to on all of my computers, and also to start using non web-based clients for as many of my apps that I can. Part of this effort includes switching over to Mastodon.el in .

    So far it has been one of the easiest Emacs apps I have ever used, and if I had known it would be this nice I would have switched a long time ago. I only wish there were a more distinct visual division between each "toot", but I can get used to the way it is now no problem.

    Bonfire: a general server with pluggable front-end modules

    ...and it is programmed in Elixer!!! This typed programming language that runs on the Erlang platform automatically gives it a powerful advantage over more mainstream programming languages like Go or Ruby, through type safety and a language runtime that is built from the ground-up to be massively parallelizable and upward scalable, and easy to debug and patch running systems without downtime.

    But from an end-user perspective, this is a social network framework in which you can install whatever front-end features you want through pluggable modules. If you want a Mastodon-like module, install that, if you want a Lemmy-like, or a Pixelfed-like, or a Frendica-like, you can theoretically just plug those in as well. From administrative tools to search and post indexing to social graph analysis, there are as many as 75 currently listed plug-ins. For anyone interested in technology, this is definitely a project to watch, and possibly even to which to contribute.
