Thanks for the free a11y audit! I fixed a number of the low-hanging a11y issues that you identified. As for using modern web tooling, keep in mind there are many business and technical tradeoffs that go into any engineering decision. In thi

Very cool! I've been considering going this direction with the videos once I've finished everything for the breadboard version. Modular PCBs would make it a lot easier to rearrange things to experiment with different architectures

I've done this and once had a phone rep from Geico who was convinced I worked for them because my email was something like geico@example.com. This was probably in the late 90s when email was still new to many people. She was really con

I always understood it to be that the "typographic resolution" aspect of sparklines was an important characteristic and that you really couldn't display a proper sparkline on a screen because most screens just don't have

The reason is because you never want routers to have to fragment your packets ever. Fragmentation is really inefficient. So any modern stack will always set DF and listen for ICMP unreachables. In other words, PMTU discovery. None of the ot

It makes fixing it possible . It's unreasonable to expect that getting millions of people to agree to take specific actions to effect a very precise change in laws will be "easy".
