🏆 II. székelydata dataviz competition

Over at my Hungarian blog (dubbed székelydata) I am launching the second edition of Transylvania’s first data visualization competition – aimed at young people and fresh university students! You do need to understand quite a bit of Hungarian in order to grasp what’s going on, but hey, I thought it would be nice to let you know. This year’s topic is climate change and it looks quite exciting already!

Rebranding

Hi all, Dénes here!

Today Try something new. Everyday. becomes Kontext. This is to reflect the broadening in scope of the blog to include complex systems analyses as well. I have recently reshaped my online portfolio into 6 distinct channels across all platforms (Facebook, Twitter, YouTube).

Thank you ❤️ for all of your support and encouragement!

Some of my projects/initiatives are incubating/dormant:

Furthermore, the following pages are dying/retiring:

ISS crew by country 🇺🇸🇷🇺🇯🇵🇪🇺🇨🇦

The other day I got into a discussion about the International Space Station (ISS), namely where does its crew come from. I started reading up on it and I figured that it is worth a quick visualization. So I’ve created an interactive one, in echarts. The data comes from here and the code is here.

The ISS has been designed to hold a crew of 7. However, that has happened only rarely, with sometimes the crew size rising up to 9 for a few days, during mission changes. ISS missions are designed to last about half a year, but of course their actual duration will vary on the launch windows and rocket failures. Missions usually overlap a few days with each other, so during crew change periods, the population merely doubles.

Did you know the ISS has been crewed continuously for almost 20 years? In the commissioning phase, Between October 2000 and March 2003, its permanent crew was 3, with American NASA 🇺🇸 astronauts and Russian Roscosmos 🇷🇺 cosmonauts rotating in a 2-1 pattern. Then, after the Columbia disaster, this was reduced to 2, before slowly starting to climb back up from May 2006.

Around this time, astronauts of nationalities other than American 🇺🇸 or Russian 🇷🇺 started to crew the station, from ESA of Europe 🇪🇺, JAXA of Japan 🇯🇵 and CSA of Canada 🇨🇦. The ISS reached its designed capacity of 7 in July 2009.

However, with the end of life for the Space Shuttle, the maximum number of people that can safely evacuate from the station using the Soyuz is 6 – and therefore the permanent crew is limited to that. Interestingly, during a crew change in November 2013, there have been a total of 9 people on the station for 3 days!

Since the stabilization of the permanent crew at 6 starting with 2011, the general pattern has been to allocate these 6 slots to 3 Russian 🇷🇺 cosmonauts, 2 American 🇺🇸 astronauts and one other astronaut: with this remaining space allocated to Japan 🇯🇵 for about half of the missions and a crew member from Europe 🇪🇺 or Canada 🇨🇦 sharing the other half.

However, one can notice an interesting switch-over starting with August 2017, from when American 🇺🇸 astronauts started to take up 3 spaces and Russian 🇷🇺 cosmonauts reduced to 2.

That’s all for today – explore the interactive graph, too!

Formula E ePrix around the world

I’ve fiddled a bit more with the F1 circuits’ geocenter map that I’ve created back in 2014, as one of my first D3.js projects.

Earlier this year, it got another update to include WRC and MotoGP history as well.

Now I’ve included Formula E. As the viewership numbers of F1 are sharply declining, I believe that the electric circus might be the next contender for the crown of motorsport. It has already overtaken F1 in the US.

Romania: where communism rumbles on in Europe

My country is experiencing another massive wave of protests. This is time it is the diaspora that came home to express their frustration with the current occupiers of our Parliament. It is the same diaspora that helped put our current president into office back in 2014, with high hopes. Yet the “thieves” (hoții in Romanian, the slogan of the protests) in the Parliament have been working diligently for the past year to create a plethora of contorted laws that will make it next to impossible to make them pay for the suffering they have caused. Yesterday’s (and today’s, and the past year’s..) protests are the crying out loud of a generation. An entire generation that was let down by its country and forced to live in exile, often on the brink of Europe’s luckier countries. Millennials, my generation.
