I'm passionate about programming, I simply love it.
I like to learn and this industry
brings to me the opportunity to discover new amazing stuff almost every single day.
Constant learner on how to improve writing clean and reliable code.
I have a hunch that once people saw the economic potential of software, they started looking for ways to "scale it up" and we haven't stopped searching yet.

Apr 11 2021Many systems are full of error checks and conditional logic. They introduce discontinuities that make reasoning difficult. In this talk, Michael Feathers will present a conceptual framework for dealing with errors, conditionality and decision making at the level of code, architecture and user interface. Often by changing design and revisiting requirements we can make various error cases impossible, and make code and architecture simpler as well as more robust.
Mar 18 2021Borrowing from Thomas Kuhn, Robert Floyd introduced the notion of a programming paradigm. Today, paradigms are constantly debated. What might Kuhn tell us about this sad state of affairs? What can Programming learn from Philosophy?.
Nov 19 2020* What Higher Kinded Types (HKTs) are and why they are useful * How they are implemented and what limitations there are * How can you use them in your own projects
Oct 30 2020A common debate in software development projects is between spending time on improving the quality of the software versus concentrating on releasing more valuable features. Usually the pressure to deliver functionality dominates the discussion, leading many developers to complain that they don't have time to work on architecture and code quality.
Oct 23 2020So you are entering a new contract, or maybe it's just a new project you are being transferred to. How do you get up, going, and committing on your first day? How to identify the areas of the system that are risky or problematic? This session looks at tools and strategies to reach this goal coming from a speaker who regularly works for less than a week with a team and needs to provide value within that period of time

Jun 27 2020The foundation ideas behind Domain-Driven Design, or DDD, are fundamentally the same as when Eric Evans brought them to our attention through his seminal work. The Bounded Context with its Ubiquitous Language is still of chief importance, along with mapping various Bounded Contexts to form a whole system solution. Even so, what has changed substantially is the computing landscape on which software developers construct and release these solutions. Systems are far more likely to be distributed, especially due to the [...]
Jun 24 2020This talk will start with basic concepts of functions, including how they are represented in memory, how state is tracked, and how function calls interact with the stack. We’ll then cover the common methods of running multiple functions concurrently, as well as the benefits and difficulties of concurrency in Python. We’ll then introduce the concept of coroutines, a variant of functions, and discuss how coroutines manage state and execution differently from functions. We’ll show some high level examples of coroutines that communicate with each other, and look at how they can be of use for I/O bound workloads. Then we’ll finish by showing how coroutines are implemented in Python, what the async/await keywords are actually doing when you use them in your code, and how all of these concepts are leveraged by the AsyncIO framework to build high performance applications in modern, clean Python. AsyncIO uses coroutines to deliver high performance from a single thread. But coroutines can be mysterious. How do they work? Starting from first principles, we’ll take a look at the basic concepts of coroutines and the unique problems they solve, then finish by deconstructing the core pieces of the AsyncIO framework. This talk is for developers of all backgrounds. No CS degree required!
Jun 12 2020The Python Standard Library is a very rich toolset, which is the reason why Python is stated to come with ""batteries included"". In such an amount of features and tools it's easy to get lost and miss some of the less unknown modules or gems hidden within the whole load of functions and classes. This talk aims at showcasing some recipes, snippets and usages of standard library modules and functions that are less known or that are not covered in the most common books and tutorials available for Python. The talk will try to showcase a bunch of short examples in the hope to foster the ""oh, wow! I didn't think about that"" reaction at least once in the audience. We will see how frequently for tasks where you used third party libraries or frameworks a solution bultin into the standard library is already available, and such solution is guaranteed to be maintained and well working for the years to come thanks to the standard library reliability and stability.
