I was working on the Advent of Code (day 7) today, which I’m using to learn a bit more about Rust, and while I was able to quickly solve the problem with python (thanks to the fact that python allows references to everything everywhere), I had a hard time solving the problem with Rust, thanks to the inability to keep around references to a “parent” in the tree. This inconvenience is by design: Rust tries to ensure memory safety by forbidding you from doing things that might potentially be unsafe....

Kubernetes uses base64 encoded secrets, but it’s important to make sure that when encoding the secrets, you don’t include any extra newlines - tldr; use echo -n instead of echo # Works > echo -n "my secret" | base64 bXkgc2VjcmV0 # Doesn't work > echo "my secret" | base64 bXkgc2VjcmV0Cg== Otherwise, you could be in for a world of pain :)

So, I had a project recently where I have a bunch of API keys, but I didn’t want to accidentally commit them to a repo (since that would be bad…). But I also wanted the convencience of just in-lining the code, and not have to worry about sourcing environment variables every time I ran the code (since this would inevitably cause annoyances). To solve this, I found a handy tool - python-dotenv, a package which handles all of the complicated bits....

So, we have a package, VDTK which we’re planning to release in a new major version - there’s only one problem… We depend on several packages which do not publish builds to the PyPi repository. In our pyproject.toml file, they are specified as: dependencies = [ "...", "clip @ git+https://github.com/openai/CLIP.git", "mauve-text @ git+https://github.com/krishnap25/mauve.git", "en_core_web_lg @ https://github.com/explosion/spacy-models/releases/download/en_core_web_lg-3.4.1/en_core_web_lg-3.4.1-py3-none-any.whl", ] Unfortunately, when you upload a package built with dependencies like this, you get the error:...

This TIL site is powered by Hugo, but it’s currently a lot of effort to create the title and name for one of these posts… It would be great if we could have a single command line tool which does this! Each post right now has the following header: # post-header.yaml title: 'November 18, 2022 - Creating the perfect archetype in Hugo' date: 2022-11-18T16:17:02-08:00 showToc: true TocOpen: false draft: false hidemeta: false comments: false disableShare: false disableHLJS: false hideSummary: false searchHidden: true ShowReadingTime: true ShowBreadCrumbs: true ShowPostNavLinks: true ShowWordCount: true ShowRssButtonInSectionTermList: true UseHugoToc: true Most of this information is super easy to deal with - everything after showToc is static, so our template can just write those directly....

Getting anything running on Kubernetes is a bit of a challenge, but today I was working on deploying MySQL so I could migrate my Ghost blog from v4.x to v5.x. This means creating a mysql instance, a user (for ghost) and any other data that we need to run the deployment. The first thing that we need to do is add a secret which will define the root user password and the password for ghost user:...
