  • To be fair, the article is trash. There’s details in other publications, like Reuters:

    "Waymo said its vehicle was at a complete stop at a four-way intersection when a large truck crossed the intersection in its direction. At its turn to proceed, the Waymo car moved forward.

    However, the cyclist, who was obscured by the truck which the cyclist was following, took a left turn into the Waymo vehicle’s path. When the cyclist was fully visible, the Waymo’s vehicle braked heavily, but wasn’t able to avoid the collision, the company said."

    Drafting through an intersection is not very safe (I really should stop doing it myself) because of this exact visibility problem. Heck, it seems our cyclist friend cut left because they couldn’t see the waymo car either.

    Watch out when crossing busy intersections, folk! Cars are bulky and opaque. Yield when encountering busy intersections.





  • Let us window gaze then!

    PUBLIC offers some nice internally geared city bikes and beach cruisers. Their 8i series is their top end. It’s steel, has a 8-speed internal geared hub, fenders included, and with handles set for upright riding. Their optional rack looks like it pairs well with the frame. 8i series drive train gearing is something on the order of 28 to 86 gear inches. The cheaper 7i series is approximately 33 to 82 gear inches. Both are quite reasonable for city gearing with the 8i being easier for going up hills and an extra gear for better cadence matching.

    Trek makes a beautiful city bike: the District 4 Equipped and has a step through version. Dynamo hub for always on lighting and the rack is included. Capable gearing at approximately 30 to 92 gear inches. IMHO, the best part is a Gates CDX carbon belt drive. Belt drives are even lower maintenance than a traditional bike chain. Never lube a chain again, battle with rust or road gunk, or become sad mid-ride with sand, mud, or ice fouling.

    Speaking of belt drives, Priority specializes in them and has a big selection of commuting and recreational bikes. They even have a folding bike, which can be nice if you’re stuck needing to drive or take a bus for one leg of a trip.

    Handsome makes frames and will build a bike to your spec. For example, you can spec their mixte bike (“She Devil”) with a Shimano Alfine 8-speed. Sellers like these are a great option, but I recommend finding a LBS willing to take a shipment and do final assembly work on it. Shipping completed bikes is expensive and you’ll still need tune-ups now and then.

    I’m sure there’s more out there, but that’s enough shopping for me today. Who else has thoughts? Or perhaps other neat finds?


  • The closest production bike available in the US similar to omafiets would be the beach cruiser. They’re available as a single-speed with/without coaster brakes, or internally geared, have wide handle bars, step-through or stylish but still easy mounting frame, and often have color-matched basket and rack options.

    Careful with what you wish for. Omafiets and cruisers work where there aren’t significant hills. Heavy single speeds really suck when you’re faces with even a moderate 4% grade. Practical urban bikes in the US really need some gearing.










  • A friend of mine explained why it’s important to his kids: they can’t chat with a group of their friends.

    Why? Because parents don’t want to install WhatsApp or other group chats due to legitimate concerns about scammers, pedophiles, and other child predators. SMS chat fills that gap, but it breaks horribly for groups bigger than 10 people. Hence if some kid is on Android, they break their chat. Given the penetration of Apple devices, it’s the kids with Android who are considered at-fault. “Just get an iPhone!”

    Welcome to anticompetitive practices targeted at your children.


  • It’s a bummer this article pushes aside the importance of calculating bearings. Figuring bearings remains a required skill in both sea and air navigation. GPS works very well, but you don’t want to depend entirely upon it when there’s life and property at risk. Sextants, chronographs, and navigational maps remain onboard many ships.

    To not be so negative, here’s something interesting the article does raise but didn’t mention: azimuthal maps are regularly projected at any place on earth. Azimithual projected at a radio station this makes pointing directional antennas intuitive and fast. It’s also helpful in grasping how a directional antenna will behave as their radiation patterns are drawn in polar coordinates and hence can be drawn on top of an azimithual map.


  • Camping in the shoulder season is great! A little cool but often far fewer bugs.

    I’ve only bikepacked once in an area more hike-a-bike than bikepacking, but I still enjoyed it. This photo is a great reminder to just get out and do it. :)

    Edit: I just noticed you strapped on a Stanley cook set. That’s easily my favorite camping set. I’ve gone much lighter these days, but I still haul that one out occasionally. It’s so cheap yet so well designed. What a nice idea to strap it onto a bottle cage/holder.


  • As is typical, this science reporting isn’t great. It’s not only that AI can do it effectively, but that it can do it at scale. To quote the paper:

    “Despite these models achieving near-expert human performance, they come at a fraction of the cost, requiring 100× less financial and 240× lower time investment than human labelers—making such privacy violations at scale possible for the first time.”

    They also demonstrate how interacting with an AI model can quickly extract more private info without looking like it is. A game of 20 questions, except you don’t realize you’re playing.
