Yesterday I got some of the Teika typer running again. Now it's time to work on fixing enhancing error messages and fixing bugs. The general technique of in-source constraints is finally realized.

This is a meaningful question, because it is a turing complete system and a very small one, so, you can get quite creative with those techniques, meaning that at some point, someone did try a specific technique for LC evaluation.

I really like how much ideas about evaluating the LC were explored, whenever I see an algorithm I can always ask myself "how would this look like if it was LC evaluation?".

Later at the compiler I do rely on the fact that there is no checks of course, but not for the frontend.

Whenever I'm doing a transformation in Teika, preserving the semantics is not only preserving the semantics under static checking, it's often quite nice to see how it behaves under dynamic checking.

A friend pointed out that this can still be done on device by Apple, I'm not sure if it is in practice tho, given of how the data is stored locally. It's still a trade-off and given that Google is the anti privacy company, it seems to be worth it for their users.

Also, keep in mind the average Android user is more likely to be older, less educated and poorer, which makes them more susceptible to fraud, so this may be relevant.

Now taking about anonymity, yes the data is in the hands of more players on Google Pay, but the chance of your specific bank leaking data is MUCH higher than Google Pay leaking data.

This is a good example to understand that there is a trade-off between security and anonymity, Google knowing all of your transactions is easily a mechanism to increase security, by rejecting suspicious payments.

Okay, this is reaaally good.

This is quite insightful.

The one who is locked by s-expressions, will never be able to enjoy the pleasure of a good notation.

It also allows to reason about untyped programs in general, just that we do not compute normally on untyped programs. This is also useful to show that the systems are terminating.

A bit of syntax and a core idea, computational reductions can only happen if the term under any untyped context, would infer to a type, aka the term is typed. This ensures that any reduction is only meaningful if the program is typed.
