I moved the antenna to a higher vantage point and updated the software a bit, so now you can see over 50M messages a day, and over 100 aircraft on the live map at peak times. Check it out at http://www.woodsidelabs.com/whatsup/
This article from Taboola shows how they use “perf” tools to analyze CPU spikes and identify inefficient database operations: https://engineering.taboola.com/leveraging-vertica-performance-by-reducing-cpu-system-calls/
Nir Eyal’s last book, “Hooked,” taught Silicon Valley how to make addictive technology. In his new book, “Indistractable,” he gives you the tools to take back control of your attention and your life.
