you could actually take every transportation engineer in your city with degrees and accolades and replace them with fed up bike guys with zero experience and they’ll end traffic violence and make streets safer in like 12 hours

SF Chronicle: Matt Dorsey's signature Cash Not Drugs program is defunct. His 2024 Measure F would have been "fiscally ruinous", would not have worked, and was soundly defeated. He is a major culture war troll on X. Therefore, we endorse Matt Dorsey for District 6 Supervisor.

@sarahjeong.bsky.social Thoughtful thread. For a while I continued visiting X for a much simpler reason: stealing jokes to repost over here. But after a while there were no more jokes over there.

I returned to Twitter/X recently. I'm not going to post a multi-thousand word justification for it. The reason can easily fit into a toot: I wanted to download my tweet archive from before it became a Nazi bar. Now that I have the archive, there's no reason for me to ever visit there again.

More and more sites are having to set up defenses from AI bots. It is costly to provide online services and they were not built for bots. One can say that the AI companies are performing a global denial of service attack, which incurs costs to all of their competitors, as well as the rest of […]

Years ago I noticed how the times of day that right-wing trolls were active looked a lot like Moscow working hours. And also how occasionally when I replied to them in Russian, they replied back to me in Russian too. When I talked about this, I was called paranoid. Freely admitted; doesn't mean […]
