I find incrond works way better.

Although he won't win any awards for his vocal skills, this was the song that drove me in my early years in college as I learned what a hacker really was and learnt more about GNU at a time when everyone miss-pronounced it as Linux.

GNU Parallel

Unlock the power of multiple cores in your command lines!

I've tried hard to get libreoffice and dvddisaster to render in a terminal but for some reason it never works... 😏

I literally can not think of anything software wise, especially FOSS as I use the command line a lot and those tools and concepts go back decades. Being a retro computer geek I can list a ton of old proprietary systems or software that I consider perfectly usable.

Oh wait, I just thought of one: RiscOS Open. The best OS for ARM besides Linux, all my Pi's run on it and it natively uses BBC BASIC, although not Free as in Freedom BBC BASIC, or even BASIC in general is a programming language that has a lot to offer.

Although not software I think the biggest thing I have in mind would be Optical Media. Most consider it obsolete, even against data tape, but I use it extensively precisely because it has features no other media possesses (ignoring LTO tape). Featurea such as many decades of longevity, cheapness (even today it's cheaper than equivalent sized flash media) and above all it's the only media that has read only properties.

SSD's, HDD's are not close to archival grade, only optical and tape (ignoring film and the ultimate archival media, vellum) are.

All my data that must be recovered at all costs is archived to BD-R, which in turn is backed up to LTO tape, which in turn is backed up into the cloud. Both the bd-r and LTO tape are written and finished days before the data has been uploaded to the cloud! Because my upload speed is 20Mb/s maximum the old SCSI LTO 4 drive writing to tape at 60MB/s wipes the floor with it, the bd-r records much slower than that but still is done in a fraction of the time.

Maybe if I'm ever able to get 1Gb upload bandwidth I'll use the cloud more, but at the moment it's running at a slower speed than my first 486 with it's 210MB HDD!

Edit: Ah! Wait, I forgot to mention Window Maker. I use Window Maker as my window manager. Works like a charm and hasn't changed in looks one bit since the 90's

Many like myself don't like the old idea of downloading stuff that "just runs". It's too much going back to the old ways with windows where you randomly just downloaded a binary off a website and ran it.

Basically it's the equivalent of sideloading apps on mobile devices. I won't do that either unless it is required.

Now I do have one such app, in appimage which is my preference anyway. KDEnlive, which I run as an appimage Vs the Debian package only because I'm on Debian 10 on my main machine and have yet to pencil in the upgrade time.

Now, GNU Guix is interesting. Cryptographically secure and verified compilation (or pre-compilation) of source code straight from GitHub etc. Now, that will be more like it!

I have in 10 years of being on Signal never managed to get a single person to be upgraded from SMS to a proper Signal contact.

Plenty of WhatsApp contacts.

I was using Signal to replace the default SMS app on my phone specifically because it was Free Software and I trusted it more as the SMS app. It had nothing to do with privacy, you don't get that on SMS, but to do with trusting the code.

Alas I'm now using the built in app and have uninstalled Signal.
