Self-signed company cert issues: make sure nix uses proper CA during nix build

1. Configure Determinate Nix daemon to know about cert whereabouts:

sudo vim /Library/LaunchDaemons/systems.determinate.nix-daemon.plist

add the following environment configuration:

<key>EnvironmentVariables</key>
<dict>
  <key>NIX_SSL_CERT_FILE</key>
  <string>/etc/nix/macos-keychain.crt</string>
  <key>SSL_CERT_FILE</key>
  <string>/etc/nix/macos-keychain.crt</string>
  <key>CURL_CA_BUNDLE</key>
  <string>/etc/nix/macos-keychain.crt</string>
  <key>GIT_SSL_CAINFO</key>
  <string>/etc/nix/macos-keychain.crt</string>
  <key>REQUESTS_CA_BUNDLE</key>
  <string>/etc/nix/macos-keychain.crt</string>
</dict>

2. Restart nix daemon:

sudo launchctl bootout system /Library/LaunchDaemons/systems.determinate.nix-daemon.plist
sudo launchctl bootstrap system /Library/LaunchDaemons/systems.determinate.nix-daemon.plist
sudo launchctl kickstart -k system/systems.determinate.nix-daemon

Nix and Github

Nix downloads packages from Github and you may quickly get rate limited by Github. For that not to happen, generate a token in Github and add it to nix.conf file as:

access-tokens = github.com=<access_token>

Nix fetchFromGithub: how to figure out SHA256 hash of a revision

If you have access to lib, then set sha256 = lib.fakeHash, run the build, check the error message, it'd show the real hash value which you can then take and set.

Otherwie you may use nix-prefetch with fetchFromGithub command specifying the repository details, as shown down below:

nix-prefetch fetchFromGitHub --owner catppuccin --repo alacritty --rev main
The fetcher will be called as follows:
> fetchFromGitHub {
>   owner = "catppuccin";
>   repo = "alacritty";
>   rev = "main";
>   sha256 = "sha256:0000000000000000000000000000000000000000000000000000";
> }

Configure programs with home manager

Most of the packages have home-manager support, for example
wezterm has this page that tells what options you have to configure it:
