    Project mention: An Ode to Ruby | | 2022-01-10

    So you are accusing me of lying, how lovely of you!

    Let's see if your accusations can hold up to Socratic questioning:

    - If I haven't open sourced any Crystal projects does that mean I haven't written any?

    - I have published several Ruby gems[0], when was the last commit or version bump for any of them? You're more interested that I am, tell me. I really should archive them, thanks for reminding me.

    - You missed off my Gitlab, what was the last public contribution I made there? (hint[1])

    - What's the last gem I created? I reckon it's this one that I didn't publish[2] because the Rack team changed a public API in such a dumb way that I'd have to rewrite it and then mucked me around with a pull request to Rack that one of the core team copy and pasted in as their own commit while arguing against the pull. Weird, but lovely people, like yourself. Meanwhile, your cookies lack security. Yes, I want to continue working within this language and ecosystem… Does the sarcasm come through in my writing?

    - Why did you not check the Crystal repo?[3][4] Github has a search facility. Put my username in, and pick `commits` on the left.

    - How did you miss the forks of[5] and Fancyline[6]? They're right there in my public activity log. Did you not see the merges into Fancyline of my code?[7] I have more to give, just trying to find the time.

    - Did you not see forks with commits such as[8],[9], and[10]

    - You didn't see I'd provided a project[11] for Mint so it can be run easier with Docker Compose?

    - Aside from that I have a whole host of changes to[12] still to push up. You can't know that but you might've guessed that I was at least working with that - and all the other forks of Crystal projects I have.

    That is all public and not the half of the Crystal code I look at.

    Should I expect an apology? If you were too cowardly to be straightforward with your accusations then I find it stretches credulity far beyond breaking that you could be big enough to provide one. We'll see, like you, I've been very wrong about people in the past.
