Why does it matter if fleet response sit in Manilla, Miami or Milan?

Surely what matters is the architecture:

> The Waymo Driver evaluates the input from fleet response and independently remains in control of driving.

Waymo tell us that fleet response agents can only provide waypoint suggestions, they don't have steer-by-wire remote control of the vehicle.

Similarly, I learnt PTC Pro/ENGINEER (now Creo) in university and have tried to learn SolidWorks, Tinkercad, Onshape and FreeCAD but never found them as usable or powerful as ProE. The constraint system, 2D sketch tool and assemblies were hard to map into these other systems.

I feel it’s similar to having learnt Photoshop (7) and then struggle to use GIMP. I keep looking for tools that aren’t there, expect panels to show certain details and they come up short.

It reinforces for me how valuable usability and interface design is for power user tools. But also, how important training materials are, and how loyal a user will be once they are accustomed to completing a workflow with their tool of choice.

Hive is more complex and less constrained than Onitama (bigger decision space).

We tried Hive when my eldest was 6 and it was beyond them. We tried it again a few years later at 8 and it clicked, has been part of our regular rotation of games since.

I disagree. You can teach a 4-year-old the moves each chess piece can make, but expecting them to absorb strategy, or to visualise 2+ moves into the future is an unfair burden.

The following are much better perfect information games for kids. I play each with my kids and have listed the age when they were able to strategise 2+ moves ahead:

- Gobblet Gobblers (4)

- Onitama (6)

- Hive (8)

eventually they’ll go to (pre-)school/daycare[0] and you’ll get some time back. it gets better.

[0] at least, they really should. kids need to socialise with others their age

Upper Story’s Turing Tumble and Spintronics are solid favourites in our house too. Weaving a graphic novel into the instruction / tutorial book is a brilliant tactic which really helped my eldest grasp the concepts covered.

Spintronics also helped give me a new perspective on electrical current, current division and capacitance. Seeing and feeling resistance in the chain, how little/no load results in high current (chain link throughput) was more valuable than the “water in a hosepipe” analogies I learnt in my University EE classes. Really looking forward to induction in the expansion set.

I was curious about the company, and discovered that the co-founders are a husband and wife couple who were in engineering and education respectively before starting the company. I’m glad to see they are able to operate profitably without listing on Amazon, and hope they continue to release more excellent educational engineering toys that I can explore with my kids.

Another great small budget movie is Primer (2004).

It has one of the biggest Budget to Box office multiples I know of: ~120x ($7k -> $841k)

iMessage supports attachments up to 100Mb and groups of 32 participants. It’s certainly more resource intensive than 140 byte SMS.

> In the AI space it's unclear what/who they could buy

They bought the most promising AI startup in the world for $650m and failed to integrate it or make use of it until ChatGPT was released.

That was DeepMind, nine years ago.
