As best I can tell Goyal started adding AI-related code to Calibre back in August, merging the LLM tab work from https://github.com/kovidgoyal/calibre/pull/2838, and created the chat widget in November with commit 41d0da4267dc6f7f7e48fb9bb7e8609a2e251cb7. I looked at forking the project myself: the challenges are that it's a very quirky application, its design and implementation doesn't share conventions with any other application, and the build system is complex and unique to Calibre. It's a shame there's no good open source ebook library application with a more conventional design. Shoving AI into everything, even when it defaults to "off" (for now), is getting old.

Show HN: Find alternatives to almost any popular GitHub repo

Several months ago, I built a "stealth" feature that I could use. It hasn't been advertised, and I've been the only user. As I find it useful for myself, I believe others (software developers) may like it too. So, this is the first public post about it, and if it gets any positive feedback, I may put some time into promoting it more. In essence, given that you've opened a GitHub repo (there are ~225k of the more popular ones indexed as of now), you can replace "github" with "libhunt" within the URL, and you will find the top alternatives and related projects. For example, here are three popular repos: - https://github.com/rails/rails - https://github.com/vercel/next.js - https://github.com/kovidgoyal/calibre To test it out, open any of the examples above and replace "github" with "libhunt" within the browser URL. You can also try with any

other repository as long as it's a bit popular. I'd be more than happy to answer any questions and receive some feedback. Thanks!

How would you feel if someone came out with an article about "echelon's code isn't just bad, it's outright dangerous" and wrote a whole article attacking and shaming you, just because you might benefit from it? Sure you might benefit, but there are much more constructive, kinder ways to do it. Even if he and his code aren't great, Goyal's done a lot of free public service here. Let's not be dicks.
