Thanks for the heads up, added this warning to the home screen.

"Warning: the game will speak out loud (since young kids cannot read the questions), so check your volume."

OP here, thanks for the thoughtful discussion :)

I'll think about this some more and see if some design decisions can improve the game with regards to "existential import". Thanks for introducing that concept by the way.

My feeling about this when developing the game with my daughter was that when playing a game, you are taking part in a game universe. If there were a reference to flying horses, the inference would instead be "there must be flying horses in this game". The generative gameplay which is creating cats with random attributes also suggests that blue, bouncing cats are likely to exist but just aren't pictured on the screen presently.

In early education (even undergraduate education) it's common to present a simplified model that in some cases contradicts other models, and developing the cognitive machinery to explore and understand the model one working within, its limits, and how it relates to other models may be more valuable than comparing which models better align with objective (or, academic) truth.

At least, this is the thought process I went through with some of the trade-offs about deciding what answer was most correct from the lens of various formalisms (in my limited exposure to those) versus what answer leads to the richest learning in the age-group.

Nice! Logic gates no less. We will have to spin up dosbox and try it out if possible.

That was a fantastic read, so much insight into group dynamics!

Good catch, thanks! We'll fix that.

Confirmed. The intent is anyone can audit our whole codebase in one GitHub repo for vulnerabilities and not scripts spread across many CDNS and projects which may change over time.

Hmm, it's working for me on Chrome. What browser are you using? Do you see any javascript errors in your dev tools console (provided you know what that is)?
ech085··on Say hello to Justin Trudeau, the world's newest oil executive
I used to kind of like Trudeau Jr, but right now he's made me ashamed to be Canadian. I'd like to know the full story of how he justified this and what kind of pressures were involved.

Please let me know if you think of any vulnerability with the approach of using a URL hash to store the key. Thanks a ton!
ech085··on Paradise Papers: Dear Tim Cook
At the end of the article "Apple bills itself as a transparent company." . This is news to me. The Apple is famously (infamously) secretive.

Tim Cook is doing the job shareholders hired him for. Most boards would replace him if he made no effort to minimize taxes. It's the fault of the system that collects taxes, not Apple. If a system wants to govern and collect taxes it shouldn't rely on companies to donate more than they're legally obliged. Fix your laws, Germany, EU.
