If that phrase "for individuals" means "for individuals only", then it isn't GPLv3, but some bespoke non-free license. My speculation: it was intended to mean: use it under terms of GPLv3 (for commercial purposes or

I tried to like OCaml for a few years. The things that hold me back the most are niggling things that are largely solved in more "modern" langs, the biggest being the inability to "print" arbitrary objects. There are ppx

Just to add, 'pass' has an otp extension to simplify this a bit [1] With that, you can do $ zbarimg -q --raw qrcode.png | pass otp insert <some-name> $ pass otp <some-name> # or pipe to xsel [1] https:&#

Many years ago (2011 or so?), I worked on a Rails app that used JRuby. The driving force was a small part of the app needing a Java library. I think we did see some performance benefit, or at least benefit from using multi-threaded web serv

This doesn't answer your question, but I'm piggy-backing with comments on k3s. For me, using k3s for development (not prod), the killer feature is running it in --docker mode where the node uses the local dockerd to run containers

It's not a contradiction to state something is not a problem most of the time. (Though the next point, calculating checksums prior to build, is much more significant.) Related example: on a cloud instance with SSD drive, I have scripts

Hindsight is 20/20. It wasn't /opt/nix for reasons I do not know. In the context of NixOS, there's little reason to consider FHS. Only when using Nixpkgs outside of NixOS does the /nix choice look poor. I don&

Nix living at a predefined path is integral to how it works. An executable does not dynamically link to a generic "ncurses" but (via rpath) links to a specific compiled version of ncurses (such as /nix/store/81rb87a
