I took transit to buy a monitor arm off Marketplace after work. Here are some things I saw on the way there and back.

Welcome to the American Winter In the frozen streets of Minneapolis, something profound is happening.

This is a really incredible piece. Share it widely 🎁https://www.theatlantic.com/politics/2026/01/minneapolis-uprising/685755/?gift=C-rzmQ8PsUHt15odxTKJDn7xrpPNxSpotkNz_P27oI0

Those might be taken with a telephoto/long-focus lens that makes the background look huge compared to the foreground. Might not be you, but the equipment.

I’m watching friends succumb to doom watching what’s happening in Minnesota and I want to shake them and scream “Can’t you see the people organizing? Can’t you see them winning?”. Doom is a warm blanket of helplessness that keeps you from the fight.

X/Twitter post from Spencer Pratt says: I’ve been in the public eye most of my life and there isn’t any dirt you can find on me that hasn’t already been aired. Seems like the only thing people don’t know is my voter registration, so here go: I registered Republican in 2020 and never changed it. And I wasn’t going to change it now just to check a different box. This is a non-partisan race - there will be no D or R next to my name. As Mayor, I will not serve either party. I will work with anyone who wants to help the City. No labels necessary.

The first video was from a few weeks ago, but I did sweep some drains tonight

Clear storm drains if you can before storms to prevent flooding. #SanFrancisco

San Francisco power outage today

Man it’s cold out here. 43 degrees with 20 mph wind puts the wind chill near freezing. That’s rare in San Francisco. And the fog is blowing in from the N-NE. Weird to see radiation fog move around like this. #CAwx

Family Zoning passes the first reading 7-4 at the Board of Supervisors. I've legit been working on this for 3 years. LET'S FUCKING GO.

If you showed up at a hearing, sent a letter, told your friends, or organized to make this happen, THANK YOU

S.F. Mayor Lurie’s ‘Family Zoning’ plan approved in major legislative victory San Francisco Mayor Daniel Lurie won his biggest legislative victory Tuesday with approval of his “Family Zoning” plan, which will allow taller and denser housing in city neighborhoods.

San Francisco just upzoned the Sunset, the Richmond, North Point, and a bunch of the Marina. I truly never thought I'd see the day. Huge congratulations to the local activists at @sfyimby.bsky.social who worked so hard to make this happen.

#Montreal 's just leap-frogged other cities in North America by opening the REM.

Automated. Electric. Frequent (2.5 minute headways). Fast (Capable of 110 km/h). Cheap to build. (One tenth the price of other systems)

Headline: S.F. pushes planning code changes to speed up affordable housing development

This San Francisco legislation seems good to give nonprofit housing builders more flexibility and faster approvals on ground-floor and interim uses. The city would save money, housing would be built sooner, and projects would spend less time as underused space. #yimby www.msn.com/en-us/money/...

Next Generation Transit Lane Enforcement System Advantages Modern transit lane and bus stop enforcement systems integrate advanced technologies that offer immediate, measurable improvements in efficiency and coverage. These systems address the limitations of the current TOLE program by automating key functions and reducing manual workload. Key features include: • Real-Time Data Transmission: Cellular connectivity eliminates the need for manual video retrieval from each bus, enabling faster and more efficient data access. • Automated Violation Detection: Intelligent onboard systems identify potential parking violations in real time, removing the need for staff to manually review thousands of hours of footage annually. • Integrated GPS and ALPR: Global Positioning Systems and Automated License Plate Readers automatically capture vehicle and location data, streamlining the citation process and reducing human error. • Automated Evidence Packages: The system generates complete, review-ready evidence packages, allowing enforcement staff to process up to five times more violations with existing staffing levels. • Enhanced Imaging Capabilities: High-resolution cameras with low-light functionality ensure accurate violation capture in a variety of lighting and weather conditions.

I guess both hardware and software. From the staff report: www.sfmta.com/media/43898/...
