In your opinion, which FOSS software is by many considered "old" or "obsolete", but are in fact, in your opinion, in many ways better than the newer alternatives?
I'll start:
Sadly, oftentimes, Forums are replaced by discord, despite... how different those are.
And, discord is inferior in so many ways. Not only you can't easily search for the content, you also need an account on centralized proprietary software, that also is quite resource heavy. Not to mention the privacy concerns.
It's also very hard, if not impossible in some cases to find old conversations on discord, vs forums where they're mostly preserved for eternity.
RSS was absolutely the shit
Do people not use it anymore? I still do. I follow a boatload of different youtube channels, webcomics, blogs, etc. If there's some other way besides RSS to have all of those updates show up on a single page, I don't know it.
That's what I used twitter for tbh. Since everyone is on it it's easy to follow people, get instant updates and maybe even discover something new through the people you follow and their likes. It's really a shame it went to shit, it was the lurkers perfect tool, especially when it comes to artists or content creators.
The Thunderbird desktop mail client is far better (feature-rich, stable, interoperable) than any webmail or phone app mail client I've ever seen.
Microsoft Outlook, from what I've seen of it, is horrible compared to Thunderbird. Why anyone would use the former is beyond me. You can't even easily see message headers, so how the hell are you supposed to know whether a message is legit?
Agree on RSS.
Don't have enough experience with XMPP.
IRC is not a secure protocol, I think matrix takes the cake there. (although I really miss IRC)
Lemmy and Reddit do have an upvote feature and aggregation across different topics / communites, which I think it's what old school forums lacked.
The real problem with IRC had always been that it didn't really scale. It's fine for a few hundred people, but eventually shit just breaks.
XMPP is very underappreciated.
audacity. that shit was mature in the 1990s.
I too prefer forums over news aggravators with comment trees.
I can’t quite find the blog post but I saw someone do a blog post using AWS' map reduce on multiple servers to process a dataset… and then they redid their pipeline using bash, awk, and maybe grep and a single 8-core machine did it 100 times or so faster.
Edit: found it https://adamdrake.com/command-line-tools-can-be-235x-faster-than-your-hadoop-cluster.html
Emacs vs. VS Code
USENET. Replacements aren't distributed, or make discussion group discovery difficult, or don't have decent native desktop clients, or some combination of those.
You know any good guides about how to get started with Usenet?
Because clients can present very different interfaces, it's difficult to point to a single guide, but the basic principles are simple enough: get a client, point it at a server ( https://www.eternal-september.org/ provides a free one if your ISP no longer has its own, but it doesn't carry the alt.binaries subhierarchy), download the list of available groups, subscribe to a few, read, and enjoy.
As for which client, I use Pan, but that's Linux-specific. For other OSs, I haven't a clue. If you happen to use Thunderbird for email, I think it still has the necessary support.
Keep in mind, though: USENET died in part from lack of good moderation options, so all you can do about bad actors and spam floods is block messages from those posters from being visible in your client. Moderated groups did exist, but the system basically amounted to one person having to okay every single message posted, which meant there was a single point of failure. For instance, when the moderator of rec.arts.anime.info died unexpectedly, it became impossible for anyone to post to the group.
90% of the news hierarchy is a wasteland these days anyway—I use it mostly for monitoring some of the mailing lists from my Linux distro, which happen to have a USENET repeater. The only other area doing well is the binaries groups.
If you're interested in running a server, start by making sure you have a good-sized data pipe—I'm not sure what the average size of a feed is now, but ten years ago it was measured in the tens of gigabytes per day (mostly binaries).
Forums and Wikis vs. Discord
Yes I know, they shouldn't serve the same purpose, but oftentimes nowadays people communities use discord when they should use a forum or a wiki.
uMatrix browser extension. It has been marked archived by Gorhill, last release is two years old, you are supposed to just use uBlock [Origin]. However, it still (luckily) works fine and is exactly what I want. (Sure, I won't install this for my parents.) The GUI to simply choose what you want the site to be allowed to do is perfect.
openscad looks ancient and works awesomely
I'll second IRC. I don't need my chat to be e2ee, and encryption has made Matrix a much bigger pain in the ass than it's worth to me.
Forums, too, though I'm a big fan of the distributed social media space. Lemmy has an experimental front-end based on phpBB, and I would love to see someone take that idea and go whole hog on it to create proper federated forums.
I understand why I should care about encryption, in theory. In practice, 90% of the time, I don't. If I'm texting my kids 'hey where are you?' or my husband: what do you want for dinner?' or a friend, 'hey, come hang out!' - I just don't care. And putting up with all the hassles that come with encryption via matrix... It's just, generally, far more hassle than it's worth, IMHO.
vi, lynx, mutt, and of course X11 > wayland
though also controversially, I'll take systemD over sysVinit
My distaste for systemd has been replaced by my distaste for netplan.
Rings a bell. Will check it out. Looks good at first glance.
