Remember when the Internet could go for weeks or even months without a major outage? That was cool.

DownDetector is another useful tool for checking site availability. Also hosted on Cloudflare.

Trying to measure coding productivity is, and always will be, a fool's errand.
Why? Because I can go for a walk then take a shower and have an idea, then write a single line of code that fixes everything I was working on.
