PLISS 2017, programming languages in a castle

Last month I spent a week in a summer school in castle in Bertinoro, Italy, learning about programming language implementation.  As soon as I saw friends talking about this summer camp my eyes were shining with excitement. It was a great opportunity for me to know more about research in programming languages and deepen my current knowledge on it.

Creating interactive audio visualisations with Clojurescript, Figwheel and Web Audio

For years, one of the great strengths of writing code for the browser was the short feedback loop. Write some HTML, Javascript and CSS, hit refresh. See it sparkle. Rinse and repeat. In time, we've lost some of that power; web apps are a lot more complex these days, code is often compiled and our applications have a lot more state, which is lost on refresh and so our quick feedback loop is gone. Figwheel is a library for Clojurescript that aims to give us some of that power back, provided you will write "re-loadable" code. I wasn't really sure what that would entail, so I set out to make a project - a tiny library for creating audio visualisations, that would let you change the graphics while the music is playing.

The Three Pigs - how to structure your React-Redux application

Similar to the three pigs building progressively sturdier houses, we gradually arrived at solutions providing better maintainability and a more efficient developer experience. From beginning with straw, progressing to wood and now iterating further with stone, here is our story.

A pioneer's guide to Alexa

Have you seen Star Trek? If you haven’t, you should. One of the pieces of future tech that is quietly on display throughout the show is the ability to talk to the computer. Whether it’s asking the computer where someone is or ordering a cup of earl grey tea - the computer has no problem understanding the questions it is asked, and who’s asking them.

Failing with style – improved Clojure test summaries on CircleCI

Continuous integration servers like Jenkins and CircleCI can display summaries of test results, surfacing information like “which of our tests are slow?” and, crucially, “which of our tests are failing?”. We've released an open-source plugin for Clojure projects to make it easier to identify and diagnose test failures in these summaries.

A truly open conference - Lua language at FOSDEM

On the weekend of the 4th & 5th February I went to Brussels to participate on FOSDEM, Free and Open Source Software Developers' European Meeting, for the 3rd time. FOSDEM is the biggest free and open source software conference in Europe and it is the one event I absolutely can’t miss ever since I moved here.

Integration testing: You keep using that word, I do not think it means what you think it means

A good test harness is an essential safety net in any code base. Tests save us from ourselves – from writing bad functions, regressing existing features, and creating user journeys with dead ends. Most importantly, they give us a sense of trust that what we release to the world, while never perfect, is at least functional and getting better and better all the time.
