Teaching and Lectures
- Intro to Programming: Eleven lectures on low-level programming using C. Now at Universidad del Desarrollo, seventeen lectures on intro to programming using Python with a data science flavor, heavily inspired on Jake van der Plas's O'Reilly book/website.
- NLP for Data Science: Some lectures notes on handling natural languages by means of computers. I should complete this with more modern methods.
- Peek & Poke: Six lectures on computing in the 1980s. Watch the teaser trailer or read the first article in a series about the ZX80 computer. [In Progress, ETA: 2017-2]
- Parallel Computing: Ten lectures on the history and algorithms of parallel computing [In progress, ETA: 2019-1, however, it's more proablable that my awesome ex-PhD student, José Fuentes will get there first. I'll live vicariously through him at this stage. :)]
- Computational Social Science:: Using CDRs to gather information at the country scale on how people behave and how we can help society be more efficient and happier.
- Bias in the news systems of the world: (Ok, Chile, but we'll extend it) I've been working with Johan Bollen and Barbara Poblete on a project to characterize the news cycle and the outlets in the world using Twitter. You can access our News Analytics dashboard to find out more. We have been showcased in the University newspaper! (in my previous university)
- Parallel succinct data structures: My student José Fuentes and myself (together with Norbert Zhe and Meng He over at Dalhousie U) have been working on parallel construction of succinct trees. Here's our page with some experiments, and the code itself. We did this for SEA 2015 in Paris. We also designed an algorithm for parallel construction of wavelet trees (joint work with José Fuentes, Erick Elejalde and Diego Seco), which we presented in SEA 2014, here is the webpage with the code for it.
- Hazard pointers: See github page.
- Numa locks: Erick Elejalde, and myself have published code for a set of Numa-Aware locks. You can access the experiments page, or the code page at github.
- Accessibility: For my earlier accessibility work, you may wish to visit here, while for iGraph-related work, you may wish to visit this page. All the sources of iGraph are available here. Note that this work is no longer maintained.

Videos[2017-12-02 20:47:56 -0300]: In the video below, I re-enter my first computer program from when I was about 9 years old. Part of my series on retro-computing I'm working on. There's some more information in the YouTube page.
