@julesh According to this post which has been going around, 2026 is the sum of all the non-one numbers in the first 11 rows in Pascal's Triangle. (This got a bit less fun for me when I noticed they were excluding the ones)
The first 11 rows of Pascal's Triangle with all the numbers which are not one highlighted. At the bottom it says that the sum of the highlighted numbers is 2026.

At the California Science Center museum and just found some new (to me) #clamFacts . According to Wikipedia this species lives at thousands of meters below the ocean's surface and gets nutrition from bacteria on its gills which can process hydrogen sulfide from deep sea vents.
A museum display of a large white clam shell. The tag says "Giant vent clam (shell only). Calyptogena magnifica"

@potterybyosa OK, I'm not completely sure what part of the rim was intended to reduce splashing but here's the dog bowl. Hoagie was the nickname of the dog.
A ceramic bowl, wider than tall with a wide base. There are ceramic raised letters spelling "Hoagie" on the side.The rim of the bowl. The rim is thicker than the rest of the bowl.

The San Bruno BART train station seems to have (at some point in the past) declared war on pigeons. The pigeons are winning. (Present but not pictured: lots more pigeons)

Saw some scaffolding in New York and all I could think of is @marklevinenyc.bsky.social @marklevinenyc and his efforts to keep scaffolding from being permascaffolding. Of note: there seems to be some work going on here!
Scaffolding over a sidewalk on a street surrounded by tall buildings. There is a ladder going up to the scaffolding and someone in a hard hat is near the top of the ladder.

This is a good season to not get sick of #BloomScrolling ! Today I went to San Bruno Mountain, my local biodiversity hotspot, and saw a cute little mustard which turned out to be Barbarea orthoceras, native and new to me, as well as red elderberry and California poppy.
A plant which has a number of leaves which have skinny lobes. On top of the leaves are several clusters containing dozens of yellow flowers and flower buds. Each flower has four petals.A bright orange California poppy flower. To the right of the flower are leaves from several plants in a variety of colors of green, but especially the finely dissected leaves of the poppy plant.

I was let off at the new #sfmta #sfmuni light rail platform near Balboa Park station today which is not news. That has happened on and off for months. But now there are some signs about a grand opening. Apparently what makes this platform open for business is that it has a light now.

Finally got a photo which (mostly) shows the light rail stop which was removed and the one which replaces it. The platform in the foreground is removed (no longer a stop,). The arrowed sign in the distance (next to the car with the taillights lit) is where the new platform is.

Here's a photo of the stop which is being removed. I actually could see both this and a corner of the new platform standing where I took this photo, but it would take a very different camera angle to try to get both in the same photo.

Just saw two trains right behind each other. First one used the platform (even though the cones are still there). The second one didn't. It really seems to be up to what that particular driver does.

Definitely looking like the use of the platform a few weeks ago was an anomaly/mistake, as this morning I was let off using the non-platform method.
A light rail vehicle stopped on a city street. It is blocking the traffic lane and is about to turn into a rail yard. This is in foggy morning light.

No news on the boarding platform itself but the marked crosswalks at the adjacent intersection have just been restriped.

Union Station in Los Angeles is eerily similar to Diridon Station in San Jose (in terms of the ramps leading down from a somewhat narrow platform, although I guess the San Jose platform is narrower). Are they from the same time period? (Fact checking myself […] [Original post on sfba.social]

Pedestrian infrastructure in Los Angeles. The bad news: the sidewalk ends well short of the stoplight where it would be possible to cross the busy street. The good news: there is a use trail through the rosemary.
In the foreground is a sidewalk which ends and is replaced by a narrow path through a waist high rosemary hedge. There is a wide street to the left and some rail tracks to the right.

The plot thickens! This morning my train was back to the old school drop-off where the train partly turns into the rail yard (thus blocking car traffic) while people get off and proceed to various official or informal crosswalks. You never quite know what you'll […] [Original post on sfba.social]

Here's the train stopped at the last station. You can see people walking to the marked crosswalk at the front of the platform. After the people are off and the intersection is clear, the train will pull forward and into a train yard on the right (slightly out of […] [Original post on sfba.social]

Today at our favorite light rail boarding island the cones are back and there is some paint on the curb.

Boarding platform update, there is now a sign directing traffic around the island and some new paint. Not in use yet but I don't really know exactly what is planned.

Update on the last M Ocean View stop (near Balboa Park BART): the cones were gone this morning. Is this the next step to further activity? Those who voted "within a week" at sfba.social/@soaproot/1128026497403… have already lost but there's a week […] [Original post on sfba.social]

How quick is quick build? Specifically, this platform was built a week or two ago as part of www.sfmta.com/projects/m-ocean-view… . When do you predict it will enter service? (Poll in the 🧵)
