    Factorial means n! = (n)(n-1)(n-2)… etc. down to 1, where n is a positive integer. It’s used to calculate the different number of configurations of a set of elements, mainly in combinatorics.

    Like if you have four different objects and you want to know how many different configurations you can order them in, you have four choices for the first object, then three for the second, then two for the third, then one for the final slot. So the answer is 4 x 3 x 2 x 1 = 24 = 4!.





  • The project actually still hasn’t started due to ongoing litigation and budget constraints. It did get redesigned with more bike infrastructure and pedestrian bridges to cross the freeway, but local bike and pro-transit groups still oppose the project.

    One of the main arguments is that the state’s proposal is not consistent with the city’s regional plan, which says that the interstate can only be expanded if congestion pricing is also implemented to discourage additional traffic.

    At this point, the state is planning to fix up some bridges while the rest of the legal fight plays out. Expansion probably won’t start until 2028 in any case… at which point this song will be an “oldie.”



  • I once had the pleasure of cycling the Shimanami Kaido in Japan, a bike route that connects the islands of Honshu and Shikoku, hopping between all these minor islands on the way over suspension bridges carrying the main highway.

    The bike lane is protected the whole time. In one case, the bike route is actually below the deck of the bridge, and you’re on a fenced-in catwalk hundreds of feet over the channel between the islands. Views for miles over Osaka bay.

    Honestly, when I look back at my life, it’s probably my favorite thing I’ve ever done. If only the U.S. invested in bike infrastructure like that.








  • Because it’s something the EU wanted and didn’t get in the last round. It’ll be funny if Trump accepts because it basically concedes that his negotiating position is weaker than it was eight years ago.

    I’m with you though. I think a united front from all the countries where Trump imposed tariffs would be more effective at nipping this nonsense in the bud. And I think countries are shortsighted if they don’t recognize that the U.S. is becoming a fundamentally unreliable negotiating partner and their approach to negotiating with the U.S. should reflect that.



  • Can you elaborate on the incompatibility of the newest GPUs? It looks like Nvidia publishes a Linux driver for the Blackwell series and there are a number of AI applications (like supporting Triton and pysam-based methods) which seem harder to get working on Windows than on Linux.

    I’m considering switching over but I hear mixed things about Nvidia support. Some people seem to say it’s a pain to get the drivers working and others seem to think that’s an issue that’s been resolved. Not sure what to think in terms of how difficult the switch would be.
