I am sure I am not the first to do it, but I have asked ChatGPT to implement a UUID v7 function based on RFC 9562. It did not get it right the first time, but after some back and forth, it gave me this answer: import time, random, uuid def generate_uuid_v7_fast(): ts = int(time.time() * 1000) & ((1 << 48) - 1) upper = (ts << 16) | ((7 << 12) | random.getrandbits(12)) lower = (0b10 << 62) | random.getrandbits(62) return str(uuid.UUID(int=(upper << 64) | lower)) Compared to the reference implementation, it is more than 2 times slower (+117% on my system). However, the reference implementation returns a bytearray while this version returns a string after a call to uuid.UUID(). ...

I have managed a Gitlab instance for a couple of years, but for some organizations, Gitlab is overkill. For some people, Gitea is enough. However, Gitea does not have production-ready CI/CD yet. Fortunately, it’s possible to link Jenkins to Gitea. Here’s how to do it. In this post, we will first configure Jenkins to use agents in Docker. It is not recommended to run pipelines on the Jenkins host. You can run a static container or let Jenkins spin up containers on the fly. We will do both. We will connect to the containers using an SSH key. ...
