CareerCon is an event organized in various cities in Poland, dedicated to IT jobs, e.g. for programmers. You can find there many companies advertising their job offers. Entrance is free, but requires previous registration on their website. There are also some presentations every time.
24 September 2016 the event will take place in Sopot, where I will give a lecture "Pułapki liczb zmiennoprzecinkowych" ("Pitfalls of floating-point numbers"). I will talk about properties of floating-point data types, which are the same regardless of the programming language you use. I will show their limitations, common mistakes to avoid and some good practices. If you are a professional programmer or a student interested in career in IT, I'd like to invite you to come and listen.
