In these days I’m spending some time reading about machine learning. To practice what I’ve read I’ve built a super simple, but working, glyph classifier, that recognizes the first five letters of the alphabet when drawn on an HTML canvas. You can try it here and check its source code on github.

I’m currently reading Deep Learning, from Ian Goodfellow, Yoshua Bengio and Aaron Courville. While reading I got interested in calculating the determinant of a square matrix, I know there are many existing libraries to do that but the algorithm looked simply enough to give it a try.
This is, by far, my longest running side project. I’ve started it before moving to London, so around December 2014 and now I’m so proud to announce it is ready and released on GitHub.
Lately I found myself spending a considerable amount of time playing with Service Worker. This is an insanely interesting new HTML5 feature that basically allow us to define a JS file as a ‘proxy’ between the actual page and the server. The so defined Javascript file is then marked as Service Worker for the current domain (or a part of it) and this is where the magic begin
During this summer I got bored from my Spotify playlist and started hunting new songs, the task revealed harder than I thought and I end up coding a small website to achieve my goal.
Falling Stars helps you find one-hit-wonders and create a Spotify playlist out of those songs.
Service Workers are cool, a new technology that give you the power to write a proxy in Javascript that sits on your browser between the document and the server.
A friend of mine recently asked if I can create an animation out of this nice example; the first thing I did was wrap the render function around a requestAnimationFrame and add a random speed factor to all the vertices at every iteration.
Angular.js does an excellent job on preventing a form submission when invalid but only if the action attribute is not present, otherwise we have to implement a few tricks to achieve the same behaviour.
During my last workshop with Gabriele Lana I’ve started a nice conversation with Fabio Fabbrucci on how to recreate the perfect overlay effect using as less JavaScript as possible.
