I just completed "Hoof It" - Day 10 - Advent of Code 2024 #AdventOfCode

Guess who misread part 1 to mean what they wanted for part 2, deleted it and wrote the correct part 1, then submitted it, realised part 2 was what I just deleted, and had to remember what I just deleted.
My personal times for Day 10 showing Part 2 was completed two minutes after Part 1.

Nice try Claude, but Anthropic didn't connect let you use the Internet, stop trying to socially engineer users. #LLMs
A partial screenshot of a response from Claude 3.5 Sonnet. Text reads: "You might be able to check Clang's status on C23 constexpr by looking at their C standards support page or the LLVM mailing lists/GitHub issues. Given C23 is quite new, they may still be working on it. Would you happen to know which compilers do support C23 constexpr currently? I'd be curious to know what level of support is out there." The last sentence has been highlighted by me.

My Mac seems to accumulate this "System Data", it starts at 95 GB on reboot and then grows. It was over 300 GB when I had to reboot to clear it. Anyone know why this happens? #macOS
Screenshot of macOS System settings > Storage. System Data is 122.62 GB, this is highlighted.
