Ludum Dare 44: Biomass

June 08, 2019

At the end of April was the 44th edition of the Ludum Dare game jam, where participants have to make a game based on a given theme in just 48 hours. The theme was “Your life is currency”, and I made a game about asteroids. I meant to write this post-mortem earlier, but my month of May has been quite busy.


SVD Visualization Tool for 2-by-2 Matrices

December 20, 2018

Roughly a year ago, I took a class on matrix theory. Back then I was struggling to understand and visualize the effect of the SVD on a matrix. Inspired by Nicky Case's “Magnificent 2D Matrix” explorable, I decided to make a small JavaScript tool to visualize what an SVD does in terms of 2D vector transformation. Now that I have this website, I decided to clean it up a bit and expose it here.


Mini Sci-Zine #002: The Radial Velocity Method

December 14, 2018

I made a second Sci-Zine in my series on exoplanets. This time, we’re learning about the more complex radial velocity method, another technique for indirect detection of exoplanets.


Ludum Dare 43: Sacrifice This Game

December 05, 2018

Last week-end I participated in the 43rd Ludum Dare game jam. Participants in the Ludum Dare “Compo” (one of the two competitions, which I took part in) have to make a game based on a given theme in 48 hours without using external assets or code besides libraries.


Mini Sci-Zine #001: The Transit Method

November 11, 2018

Inspired by Malwine and Éléonore Mayola, I am starting a series of mini zines on STEM subjects. Today, I just finished the polished version of the first “Sci-Zine” on the transit method, a technique to find exoplanets.


“The Machine”: A Conversation With a Slot Machine

October 31, 2018

Right after my graduation (literally, the day after) I went to Berlin for the entire month of July to participate in a program at the School of Machines, Making and Make-believe. The “School of Ma” is an independent school at the intersection of art and technology, run by Rachel Uwa. Every month, a course is organized around a specific theme, and multiple instructors are invited to come and teach to a dozen or so students.
