Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Type-safe, K-sortable, globally unique identifier inspired by Stripe IDs
We have a uuidv7 implementation that we've been using with rocksdb for over a year https://github.com/matrixai/js-id

Plan B for UUIDs: double AES-128
We evaluated ULID but we wanted something that is future proof for our decentralised secret sharing system. So we implemented UUIDv7 in TypeScript called `IdSortable` https://github.com/MatrixAI/js-id
It allows strict monotonic IDs when you provide it the previously generated ID. The resulting data structure is a Uint8Array making it easy to put into binary structures. Can also be used as a key inside any POJO record.

Lesser Known PostgreSQL Features
I had reviewed existing UUIDv7 implementations and many were incorrect or had subtle timing bugs.
We ended up implementing UUIDv7 in our ID generation library https://github.com/MatrixAI/js-id. And we have a number of tests ensuring that it is truly monotonic even across process restarts.
See IdSortable.

Nanosecond timestamp collisions are common
Our Go ULID package has millisecond precision + monotonic random bytes for disambiguation while preserving ordering within the same millisecond. https://github.com/oklog/ulid

There is no "tests".
There is just a single test. Which only tests the decoding of a single known value. No encoding test.
Go has infrastructure for benchmarking and fuzzing. Use it!
Also, you took code from https://github.com/oklog/ulid/blob/main/ulid.go which has "Copyright 2016 The Oklog Authors" but this is not mentionned in your base32.go.

Is it bad to use short (20 chars) random strings as primary keys?
I'm not concerned too much about the performance or the storage size at this stage. I've checked ulids before posting (more specifically https://github.com/oklog/ulid) but the only difference than a random string (especially if you use them with math.rand) is the timestamp prefix which makes them sortable, but I don't need that (users could use the internal SQLite rowid if they needed to sort by a primary key).

Golang Base Project - A simple web app with user authentication
why are you using https://github.com/oklog/ulid to generate a cookie secret?

What are your favorite packages to use?
oklog/ulid to generate IDs. coreos/go-oidc for validating JWTs I get from auth. google/go-cmp for comparing structs in tests (unless the project is already using Testify). spf13/pflag because life's too short for Go's flag handling. getkin/kin-openapi for validating reqests/responses against my OpenAPI spec (in tests).

If you just want to roll with an off-the-shelf library, you can use ULID. There are tons of custom made *flake alternatives. If ULID doesn't fit your purposes, look for others.
