🎧 Jimmy Flores & I just launched a new podcast: say hi to Radio Lanza


Things I'm Doing

This is a /now page, inspired by Derek Sivers and the nownownow project.

Here you will find whatever I am currently doing, reading, learning, building... and keeps me awake at night, timely updated every four months.

Mid 2019

This Now chapter for Mid 2019 features a brand new Learning section 🤓 that replaces the Training section — seen in the last two chapters. While I don't discard bringing it back, after sunsetting the sub3 project, I don't feel like enduring another a training-related goal this time.


Jimmy Flores and I just launched a new podcast: Radio Lanza. You can read the story of how it came to be in the this post and links to each episode can be found in its own work page.

And despite the mic will get a lot of my attention, I will also be revamping the way book summaries are presented at collado.io. Writing summaries out of my notes after reading a book is a good habit. I want to make the most out of this content, so readers can benefit from a better experience.


Every year I usually enroll in a course around a topic I'd like to go deeper. Here are examples from 2016 (WebDev — Rails), 2017 (Data analytics) and 2018 (again, WebDev — React).

This year, though, "I don't feel like course". Yet there is a topic I want to explore further: physics.

Back in college, I hated physics. Nowadays I find myself devouring books, papers, or anything I can put my hands on that speaks physics. Several friends have recommended the Feynman Lectures — I will (re)start my structured physics journey with them.


If you've read a book in a week, you haven't "read it", at all.

This was a friend's reaction when I mentioned I was aiming to read a couple of books per month during Early 2019. Then he went on...

You don't go cover to cover and call it a day. A book is not a closed entity living in isolation. It contains a mesh of references you ought to explore, endless opportunities to learn beyond the book itself. It should persuade you to discover new ideas, otherwise, you are not truly "reading it".

...and he has a point.

For this reason, during Mid 2019, I will slow down my reading efforts and focus more on "reading" the ones I couldn't handle from Early 2019. Plus I will revisit my all-time favorite Sapiens, but embracing this mindful approach, savoring each page 😋

Early 2019

2019 will start by consolidating and doubling down on the same 2018' themes, but with a slightly different focus.


Keeping up with the obsession goal of running a marathon under three hours, the next stop, after missing the 3h15min mark — just by 39 seconds — in Valencia, will be the Sevilla Marathon on the 17th of February and my hometown' Barcelona Marathon on the 10th of March.

Both Sevilla and Barcelona should clock somewhere between 3h10min and 3h15min, the closer to the former, the better.


A growing discontent with note-taking apps has recently gotten all my attention, to the extent that I've decided to create my own thing.

I'm still not sure where this is going. I could end up nowhere with "yet another" note-taking app, finding out that it simply can't be done... or maybe, just maybe, creating an amazing product that solves all my note-related pains.

What I do know is that pansa will become one of the most delightful side projects I have ever worked on and that I'll be having the time of my life building it.


I want to keep on reading a couple of books per month, but also reinstate the practice of publishing my book notes — even if they aren't extremely polished.

Early 2019, these will be my eight (+1) book pickings:

Late 2018

In a nutshell, later this year I'll be spending more time training, coding, and reading, all the details below.


I'm back to the running track and (seriously) preparing to run a sub 3h marathon sometime next year.

By the end of the year, I hope to get my marks back down to 40min for 10km and 1h25min for half marathon.

I'll also be running the Valencia Marathon on the 2nd of December — hopefully under 3h15min.

You can follow me on Strava to know how am I doing...


After finishing the DAND and the RDND, Udacity offered the possibility to become a mentor for future students of their programs.

I was hesitant at first because such commitment would occupy a lot of time. But the idea of giving back and helping out other students achieve their goals definitely won me over and I decided to start mentoring Udacity students on the React Nanodegree.

On top of that, I'll be wrapping up other "unfinished" projects of mine:

  • Complete the moving of collado.io.
  • Finish both ES6 and JS30 Wes Bos courses that I started early this summer.
  • Read for once and for all Eloquent JavaScript which I started several times, but somehow never managed to reach until the end.


I want to maintain the healthy habit of reading a couple of books per month.

For this late 2018, my picks will double down on a topic that has recently caught my attention: the intersection of physics and psychology.

  • A Brief History of Time and The Grand Design — I read these two a while ago (back in college actually...) and I hope that re-reading them will get me in a "quantum mood" to start with the psychology stuff.
  • Thinking Fast and Slow and The Undoing Project — I read the former a few years ago and it profoundly changed the way I approach decision making, period. Recently, a friend of mine told me about a Michael Lewis book that narrated the twisted relationship between Dani and Amos. I couldn't resist the "temptation" so I'm going for both.
  • The War of Art and Man's Search For Meaning — Everybody keeps on recommending these two and now it is the time to go get them. Bouns: nicely aligned with the psychology theme.
  • Measure What Matters and 12 Rules For Life — Finally, not really the types of book I'd actively seek by myself, but these are Ironhack's Book Club picks for the month... so I have no choice.
