Ahh, the yearly ritual... shortly after renewing the domains, it's time to buy another smoke alarm battery. Luckily, I had the journal entry from the last time I had to do it which made it trivial and I already knew I only needed one battery.
It still didn't stop me accidentally setting off the test, twice. My ears are still ringing.
After that, it was time to vacuum the dust out of the heatsink on my laptop, and I vacuumed the keyboard out while I was at it.
