Questions about Deep Learning and the nature of knowledge
Jan 21, 2018
If there is something that can be assumed as a fact in the AI and Machine Learning domain is that the last years had been dominated by Deep Learning and other Neural Network based techniques. When I say dominated, I mean that it looks like the only way to achieve something in Machine Learning and it is absorbing the great part of AI enthusiasts’ energy and attention.
This is indubitably a good thing.
The Most Promising Programming Languages for 2018
Dec 31, 2017
This is the time of the year in which I propose 5 emerging/new languages that you should keep an eye on the next year. I’ve done it last year, and the year before, and the year before that.
This year, however, I am not in the mood of doing it. There are several reasons why. The first one is that this year there have not been a lot of movement on the new programming languages.
Preserving a Cryptography book from 1897
Dec 10, 2017
Some time ago I found on my grandma’s house an old Italian book on cryptography from 1897. Why a 120 years old book on cryptography was on my grandma house, is a mystery. I’d like to think that some grand-grand-parent was a late 19th century hacker. Anyway.
The book title is “Crittografia ossia l’arte di cifrare e decifrare le corrispondenze segrete” of Count Luigi Gioppi of Turkheim.
Well, I don’t know if this book is hard to find.
NaNoWriMo 2017 in Stats
Dec 7, 2017
This year I joined and won the NaNoWriMo challenge: write 50000 words for a novel in 30 days. I did it. Now the nerd side need to splat on this page all the accumulated stats.
The Novel I think it is the proper way to do it: I need to talk about the novel. The novel is, of course, in Italian and it is unfinished. With 52k words I reached barely the beginning of the third act, more or less.
Procedural Calendar Generation & Lunar Phases
Nov 30, 2017
Here we are again! This is Part 3 of a small series on how to randomly generate a physically accurate calendar starting from planet’s orbital parameters. You can find the general motivation here, part one here and part two here.
Said that, here we go with the next part: lunar phases.
Why lunar phases Lunar phases are incredibly important in a calendar. So important, that many of the early humanity calendars are, in fact, lunar calendars or lunisolar calendars.
Seasons Generation from Orbital Parameters
Nov 14, 2017
Welcome back to part 3 of the Procedural Calendar Generation series. In the first part we looked on how to compute celestial body position in a simple two-body system. The second part, instead is crash course on ellipse geometry.
In this part, instead, we will tackle a fascinating consequence of the cosmic dance of our planet around its sun: seasons. Seasons are a strange beast because their behavior depends on a huge amount of factors.
Not every classification error is the same
Oct 18, 2017
In this article, I would like to talk about a common mistake new people approaching Machine Learning and classification algorithm often do. In particular, when we evaluate (and thus train) a classification algorithm, people tend to consider every misclassification equally important and equally bad. We are so deep into our mathematical version of the world that we forget about the consequences of classification errors in the real world.
But let’s start from the beginning.
Cuphead is not "hard"
Oct 16, 2017
During the last few weeks, I’ve seen over and over people saying that Cuphead is hard. That it is brutal. That is the “dark souls of the side shooter”. For this reason, before this trend goes too far, it is time to make things clear: Cuphead is not hard.
Can a game that can easily beaten in a couple of hours be hard? No. It is challenging”, yes. It requires multiple tries, for sure.
A Dwarf Fortress calendar in PureScript + Halogen
Oct 2, 2017
My last week project involves PureScript and Halogen and the Dwarf Fortress calendar. I wanted to give a first-hand experience with some pure functional language for web front-end and, after discarding Elm, I ended with PureScript. I will not go on a comparison between PureScript and the rest of the world. If you want a comparison among the other candidates, you can look at this very detailed article. (There is ClojureScript too, if Clojure will ever came back from the graveyard).
Crash course on basic ellipse geometry
Sep 18, 2017
Because I started a small series about astronomical algorithms and the magic of math in space, I think we need to cover an important prerequisite. In the series, I will talk a lot about ellipses (duh), I will move from the semi-axis majors, to the periapsis, to eccentricity, to ellipse’s center and ellipse’s foci. I am concerned that things can get more complicated than expected if the readers does not know many of the geometric properties of the ellipse.
