Cloudflare: Debugging Perl Nightmares & AI's 80/20 Bug Fix
I n my five years of experience working extensively with Cloudflare, I've seen it all – from battling legacy Perl scripts to leveraging the latest AI developments for code optimization. You might be surprised to know how often seemingly unrelated issues can be traced back to a few key problem areas. This article isn't just a theoretical overview; it's a collection of hard-earned lessons and practical debugging tips that I've accumulated along the way, focused on how to tackle those pesky bugs and even how AI can help.
We’ll delve into how the Pareto principle , specifically the observation that 20% of your code causes 80% of your bugs (and Microsoft's even more alarming finding that 1% of code causes 99% of crashes), applies to real-world Cloudflare deployments, especially when dealing with older languages like Perl . I'll also share my thoughts on " What Killed Perl? " and how we can learn from its decline to improve our current development practices. Pl…
