That is well outside of the usual sticker shock of the cost of gas in the bay area!

FYI, Sigonas in Redwood City has a selection of panettoni available around Christmas time.

Not in IEEE 754, but there are various trans-infinite numbers in other numbers systems, culminating with surreal numbers.

Godzilla Minus Zero - Wikipedia

The IEEE 754 floating-point arithmetic / kaiju cross-over movie we've all been waiting for _Godzilla Minus Zero_ (also stylized as "Godzilla -0.0") is slated for release in late 2026!

"Godzilla NaN" next expected sequel for an unordered challenge.

Now just over five weeks until the Dec. 4, 2025 start of JDK 26

For those of us in the bay area, with one of the first rain storms of the season, a reminder to check the local storm drains to see if they are clear of debris blocking their flow.

I'm seeing lots of AI generated Java Dukes appearing with a mouth, feet, ears and more. Tip: when using AI, upload this β€œDuke Specification” image, prompt AI to follow as a reference. I think you'll find the resulting image is much better. Ex: "draw duke on a skateboard referencing this spec image"

Given prop 13, new funding for local bonds or similar?
(In my area, a larger portion of the water bill was transferred over to the property tax bill.)

Also at the time, the door sets came with both rounded-corner and square-cornered strike plates, matching whatever you might already have.

Baldwin Hardware Online | Baldwin Hardware Direct Browse our catalog of high-quality Baldwin hardware online. We carry doorknobs, locks, levers, touchscreen entrances, and other handcrafted home accessories.

I ordered from www.baldwinhardwaredirect.com per-acquisition. At least at the time, you could order different finishes for each side. I used that feature to have a chrome finish inside the bathroom, matching the facets, etc., and brass outside.

One of those outlet wiring testers is a good tool to have in one's electrical toolbox; trust-but-verify all the existing work too.

Agreed; switching out the builder-grade door sets is a worthwhile upgrade. Too bad about the buyout.

Updating the switch plates of the outlets from the stock plastic ones is an easy cosmetic upgrade too.

A Silicon Valley engineer’s go-to lunch spot closed. So he bought the place. During John Vink’s Apple and Google years, this pit-smoked chicken in Sunnyvale was a constant.

Not currently. I'll post messages here once we start making public pushes of this work, branches in the Valhalla repo are a likely first destination.

Even if solar provides dirt cheap generation for utilities, given regulatory capture benefiting those utilities, not guaranteed customers would see any cost savings.

Also good for increased local resilience against earthquakes, wildfires, and any other disaster.
Prior to the multi-day outage for my neighbor, I had two nearly 24-hour outages from PG&E less than 6 months apart. If I didn't have some on-site portable battery storage, 2X loss of fridge contents.
