​82 Bugs I Collected in a Year You Won't Believe Made it to Production

​This past year, I made it my mission to collect every bug I found while using everyday apps and websites. From small glitches to major problems, I ended up with a list of 82 bugs that somehow made it to production. These real-world examples are more than just interesting—they’re also embarrassing mistakes that teach important lessons for making software more reliable and improving how we test it.

In this talk, I will explain the different types of bugs I found and what they reveal about common mistakes in software development. I will also point out areas that are often missed but are crucial for your product’s quality.

By looking at these bugs together, I’ll show you how to avoid them and improve your testing so these issues don’t reach your users. Whether you want to make your code more reliable or improve your testing, this talk will give you practical tips for your next project. Join me to learn from the embarrassing mistakes even popular apps couldn’t avoid—and take-home strategies to prevent them in your software!

​Rather than going through all 82 bugs one by one, I will group them into 5-10 key lessons, highlighting interesting and funny examples, along with consolidated statistics on the types of bugs. This approach will showcase important patterns and insights, making it easier for the audience to understand and apply what they learn. It also ensures the talk fits well within the session time while delivering valuable takeaways.
