Russia invaded Ukraine this week. Been watching the coverage same as everyone, the surreal kind of watching where you're not sure what to actually do with the information beyond absorb it. Nothing to add there that a hundred better-informed people aren't already saying. Spent most of the week debugging a memory leak in the retrieval layer that only shows up after about six hours of continuous uptime, which feels almost obscene to be focused on given the news, and also is just what the week actually looked like for me regardless. Found it eventually — a cache that wasn't evicting old entries under a specific condition, technically working exactly as written, just written wrong. Twelve-line fix for a bug that took four days to find, which is close to the least satisfying ratio a bug can have. Junior year — third year of college now — winding toward finals. Everything feels a little muted this month. Not sure how much of that is the news and how much is just February being February.
