Understanding Nix Inputs

Every Nix derivation produces a Nix store output that has 3 things:

• Executables
• Libraries
• Data

Executables are always exported using the PATH environment variable. This is pretty much automatic.

    struct SoundIo *soundio = soundio_create();
    if (!soundio) {
        fprintf(stderr, "out of memory\n");
        return 1;
    }
    int err;
    if ((err = soundio_connect(soundio))) {
        fprintf(stderr, "unable to connect: %s\n", soundio_strerror(err));
        soundio_destroy(soundio);

Roslyin Compiler Support for Type Classes

This documentation describes potential implementation of Type Classes and Shapes features in Roslyn compiler.

Goals:

1. Provide a solution without extra modification of .NET CLR
2. Stay backward compatible so previous versions of C# programming language can use generic types constrained with type classes
3. Stay CLS compliant
4. Provide interoperability between different .NET languages

Nix CA Certificate Handling

Some applications requires contacting HTTPS endpoints. In those cases you need to supply the CA certificates.

Most Nix applications won't package in the CA certificates, this is because they can make use of the OS provided CA certificate store.

The NixOS location for this is at: /etc/ssl/certs.

The OpenSSL library in Nixpkgs is compiled to use that path if there is no environment variables such as SSL_CERT_FILE.
