Ping at the speed of light dives into the computer networking weeds with how fast packets travel through the internet plumbing. The author created a Python script that scrapes network speeds from disparate locations to see what the network speed is in fiber optic cables as a percentage of the speed of light.
The critical path: optimizing load times with the Chrome DevTools provides a well-written explanation about using Chrome's developer features to improve the performance of your websites and web applications.
Three takeaways for web developers after two weeks of painfully slow Internet is a must-read for every web developer.
