GoCracow #3

It's a meetup for fans of GoLang or people who want to know more about it.

If you want to be a speaker just let me know :)

At the end of the event, there'll be free pizza! We have only 70 slots available so do not wait with RSVP :)

• Gopher in performance tales (description):

The presentation is about performance aspects in Go (mostly), but sometimes in general. Go is allegedly a very performance focused language, so we try to find out if we should migrate our existing project codebase to Go, because of its performance. Moreover, perhaps we should start thinking today about choosing Go for new projects because of the same reason? Many developers face such dilemmas and we can't avoid it among Gophers as well.

During this presentation, I will present some basic tools in Go which help us in terms of performance and show some use cases and gotchas in this area. And we will try to figure out the answer: is Go really suitable if the performance of our application is really critical?

• TDD done right - tests immutable to refactor (language agnostic)

Do you feel tired when you see a lot of tests failing just because you’ve introduced simple business logic change or done some small refactoring? And maybe your tests do not make you feel confident when developing new features?

In this presentation, I will show real code examples of how to write tests that will help you develop new features fast and safely. A lot of practical do's and don'ts based on simple microservice project implemented in Golang. All ideas will be language agnostic, so you can apply them in any of your projects :)
