Many years ago, a car racing sim friend and I built a very DIY no frills rocking chair that I hooked up to a sim. The racing sim was open enough that you could output the lateral acceleration via seri…

Congrats on the launch! Very small thing, but I didn't initially see the database icon in the sidebar. Trying to `from replit import db` in Python and using the `db` resulted in an unclear error …

Good point. The terms[0] say that "The cards must be used in person at a physical point of sale. They will not transact eCommerce purchases." but a square terminal might/should work (yo…

Agreed, I was first perplexed at what was going on, starting to not see where it was going at all with the low-level explanations, and then when the enemy positions turned out to be assembly instructi…

Sorry, I didn't follow the launch. Does anyone know whether App Clips can consume/produce audio? I'm working on a musical app -- is there a way for us to "demo" our app in App…

Just to make sure I understand, which "whole thing" is misleading? The ACLU's test? Amazon's response? As for the test, you say it's not a fair test. The point / conversa…

You're right, thanks. `dig www.amazon.com` for both `@8.8.8.8` and `@8.8.4.4` return no IP addresses. Same for CloudFlare's `1.1.1.1` ... ouch.

To which URL are you connecting? amazon.ca is up for instance.
