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 techn…

Real Engineering did a video about this recently: https://www.youtube.com/watch?v=vMTchVXedkk

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".

This seems likely, but also easy to work around by advertising a smaller window size. When you send ACKs, not only do you send the acknowledgement number indicating which byte you …

I was in exactly this situation back in 1996. I moved back in with my parents and enrolled in a couple classes at the local community college. I guess the assumption was that I'd g…
