Hauled some stuff on the bike. Birthday party supplies got to the park faster than they would have in a car.

Pretty disappointing to see SFPD parked in the bike lane directly in front of their station, just 50 feet from their designated parking lot.

So I had Claude analyze if there was a statistically significant correlation between the day an app was submitted and review times, and the results are somewhat interesting. Ship on Sunday or Wednesday for the best results.

Yeah the majority of these homes are not actually long-term vacant. These are mostly homes that are in the process of changing owners/tenants. There are still some long-term vacant homes, sure, but… far fewer than you suggest.
For rent 34,278 31.4%
Rented, not occupied 9,998 9.2%
For sale only 5,636 5.2%
Sold, not occupied 4,500 4.1%
For seasonal, recreational, or occasional use 13,850 12.7%
For migrant workers 92 0.1%
Other vacant 40,885 37.4%
Total 109,239 100%

So artists must perform for everyone, but public servants can opt out of providing services based on their own bigotry? Make it make sense!
"Any artist cancelling their show at the Trump Kennedy Center over political differences isn't courageous or principled-they are selfish, intolerant, and have failed to meet the basic duty of a public artist: to perform for all people," she said.

California Disability Benefits application process is kafkaesque
When to File Your Claim

You can file your claim on the first day of your disability, but to avoid creating delays on your claim, losing benefits, or having your claim disqualified, you should file your claim:

No earlier than nine days after your disability begins.
No later than 49 days after your disability begins.

Cargo bikes change everything. 200lbs of cargo capacity is more than enough for most errands and trips.

SB 9 lot split notice just went up near my childhood home! State law gets the goods: lot split can’t be appealed, delayed, or denied.
