Thanks Berkeley neighbor for adding back a safety barrier to this bike hazard on Virginia & McGee. I noticed last night someone removed my cone &I was going to replace it this week. City of Berkeley still hasn't put in a permanent fix.

I am curious how the repair rate on these will compare to hybrids. Hybrids are great for range, but they tend to have a higher repair rate than either ICE or EVs. Is the onboard gas generator a simpler and more reliable solution vs hybrid engines?

Emergency alert from the City of Berkeley. City found some explosive photography chemicals in a residence near Colusa & Tacoma, right near Thousand Oaks school just a block from Solano Ave

"But photography was supposed to be a fun hobby" they said

PG&E Outage Center

Brief power outage in Berkeley near the North Berkeley Bart station. Only lasted a few seconds. PGE.com/outage doesn't show anything so it must have been brief for everyone

My other favorite Google Easter-egg is the title for the Google 404 error. It contains an humorous typo.

This Google definition for "Pedantic" doesn't explain what Pedantic means. This is irritating.

Today I realized is an Easter-egg-- It's written this way *because* it will irritate the pedants. Well played Google. Well played.

Google's Gemini 3 is apparently causing a fair amount of load on the Google infrastructure. Folks are complaining about errors like "We are at capacity, we'll be back soon" since at least yesterday.

For me just now, Gemini on Google Docs is very slow.

This code is full of twisty little passages, all alike. A comment, probably the remains of a luckless developer, lies here.

Trains are not stopping at 12th St. Oakland City Center Station in the Antioch and Richmond directions due to a medical emergency. Trains are able to run through and continue on to 19th Street. Trains in the SF and Berryessa directions are still making stops at 12th Street.

I love Linux.

* Data storage: "flushing" typically means syncing in-memory data to permanent storage, like disk
* Data caching: "flushing" usually means clearing the cache
* Lunux Host Firewall (iptables, netfilter), "flushing" means deleting all the rules & exposing your host to the internet

Note that fighter jets usually cannot be seen with Flightradar, but ADSB Exchange tends to show them. I'm not fluent enough in that world to know enough though.
