zalgo.fnl

1. Like many Lisps, Fennel is extremely permissive about what it considers to be valid identifiers in code so long as delimiters like ()[]{} are properly respected and known identifiers/symbols (builtin macros/special forms, known functions, etc) are left alone.
2. And by anything, I do mean anything.
3. Zalgo-text generators have been pretty popular lately; they more or less just dump patterns of garbage unicode codepoints between the actual characters in strings until computers can no longer properly render it. It's pretty funny; sometimes it will look different in different contexts even in the same application on the same machine.
4. So why the hell not, let's have Fennel compile itself to zalgo.

Network Isolation of Services with Systemd

Network namespaces are an important component of containerization in Linux. A network namespace (netns) allows a running process to see different network interfaces, routes, and firewall rules from the rest of the system. There are a number of use cases for network namespaces, such as running multiple servers, testing/staging environments and providing isolation of services.

Creating a Network Namepsace

We begin by creating a generic systemd service for creating a named network namespace. I add the following to /usr/lib/systemd/system/netns@.service. In systemd, the @ mean the service takes a parameter which is passed to the unit via %i. E.g, we can run sudo systemctl start netns@webserver.service.

Expression for a buildEnv-based declarative user environment

This is one way of managing your user profile declaratively.

Alternatives include:

• an attrset-based nix-env-based environment, installed using nix-env -ir rather than nix-env --set. LnL has an overlay which shows a way of doing this.
• home-manager, which provides NixOS-like config for your $HOME

Note that this is incompatible with regular imperative use of nix-env, e.g. nix-env -iA nixpkgs.hello. It has the advantage of allowing the installation of multiple outputs of the same package much better than nix-env's builtin profile builder does.
