Hello, it’s another weekly log.

I have been away since last Wednesday, so this log actually covers the week before last.

In the “recently completed” category, we have items in three areas:

**GSoC** :

- [Haskell projects were accepted!](http://discourse.haskell.org/t/gsoc-2024-accepted-projects/9491) Thus I will be mentoring one contributor who will expand my CI auto-recovery tool.

**Stackage** :

- I finished reviewing the logic of all the background processes.
- I opened a few issues/questions that came up during the review.

**GHC CI** :

- Got rid of the “Signal 9” spurious errors with [Patch 12507](https://gitlab.haskell.org/ghc/ghc/-/merge_requests/12507), closing a [long-standing issue](https://gitlab.haskell.org/ghc/head.hackage/-/issues/38) that affected multiple repositories.

Coming up, I will continue working on a Stackage presentation for the Ecosystem Workshop (hence the recently-completed process review). I will be creating or updating documentation along the way.

Last week was another slow week for personal reasons, so I don’t think it’s worth its own post. I am continuing to work on the Stackage presentation!

Sorry, another slow week. I’ve done a deep dive on how stackage works (hmm, I could have just made that the subject of these logs!), because I think creating an introduction to stackage internals will be a valuable contribution to the community. The talk I will give in a couple weeks will be made public after the event, so you’ll all get to see the fruits of this work soon.
