Claude 3.7 Sonnet and I have vibe coded automatic OpenGraph image generation for Hugo. I found a bunch of other ways of doing this like I linked to before, but this uses an incredibly simple technique: use the canvas library to draw the logo and post title, and save the image. It’s much simpler than trying to wrangle Puppeteer or Playwright, which are great but huge overkill for the simple text-heavy styling of this site.

As I’m working on my new AI startup Rivets, I’ve been setting up a GitHub App. That’s not an OAuth app, but the second type they provide, where the app can operate as itself as opposed to operating as you on your behalf. There’s an excellent PHP library lcobucci/jwt available to handle the meaty parts of generating JWTs, but I had some trouble getting it working with GitHub Apps specifically, as there are some quirks, and not a huge range of examples.

The more I use Coolify, the more I’m impressed by it. It’s a great alternative to platforms like Laravel Forge, Vercel, Heroku and others. Following on from my previous post about setting this up, I’ve also published a Github repository to make it easy to get started. Coolify handles everything I’ve thrown at it, and I’m using it in production with PHP, Node, Python, Postgres, and MySQL. If you work across different technologies or like to experiment, it’s never been easier to take back control from the cloud and run things on your own servers.

I’ve recently had to shut down some old platforms. This presented an interesting challenge, as I had some requirements: No ongoing server costs/maintenance Custom error messages depending on the domain, so the solution can be applied to multiple legacy platforms Work across wildcard subdomains, which are used to identify the tenant I already manage DNS through Cloudflare, and after investigating their Workers a little bit, I found that they provide the perfect solution.

Whilst shutting down some old projects, I’m archiving all of their folders and storing them in S3 in case of an emergency. I don’t have AWS credentials stored and set up on the EC2 instance, so I’m passing them through as variables to the script below. As with the script to export tens of thousands of individual MySQL databases, you’ll want to edit the values at the top. EFS_MOUNT_POINT is the full path to where the EFS drive is mounted S3_BUCKET is your target S3 bucket AWS_… self explanatory!
