Michał Urbańczyk reports a new STANDUP for yesterday (2022-02-10):

Today: I've attempted to implement the musl setup described by the Graal VM documentation to unblock Edward's PR. However, I've encountered issues. First was issue with current musl.cc releases (they are bugged), then environment mismatch with building Rust parts.

While doing checkup on the fail CI jobs I've noticed a few ones that might need some attention — I've brought them on Discord.
The nightly release on staging repository was completed for the first time, no issues were found. It should be finished by 2022-02-11.

Next Day: Next day I will be working on the ##181207398 task. see below (Enso Bot - Feb 11, 2022)

**Michał Urbańczyk** reports a new **STANDUP** for today (2022-02-11):

Today: I've found a way simpler solution that unblocks Edward's Graal VM bump PR, so I went with it and fixed the issue on the SBT side rather than move logic to Rust. Also applied some minor touches to stdlib tests to make them pass.
PR successfully landed.

Looked more into CI issues from yesterday. I've seen that Postgres handling is misbehaving from time to time, I have a possible explanation to this, will try fixing this soon.
Fixed the random failure on macOS related to the icons generation. It should be finished by 2022-02-11.

Next Day: Next day I will be working on the ##180302898 task. Get to the unified IDE + Engine package building. (Enso Bot - Feb 11, 2022)
