The magestic r/place

The April 1st social  experiment on Reddit turned out nice this year. Users were enabled to draw on the huge canvas, one pixel per 5 minutes for 72 hours. It resulted in a great example of co-creation.

r/place is a collaborative canvas on which a single user could only place a single tile every five minutes. This limitation de-emphasized the importance of the individual and necessitated the collaboration of many users in order to achieve complex creations. Each tile placed was relayed to observers in real-time.

The full 1000×1000 pixel picture have already been printed on canvases and puzzles by some redditors. Probably a couple of tattoos will follow.

Great detailed description of the project architecture is provided by Reddit on their blog. Absolutely fascinating reading, at peak times 80,000 users were at r/place simultaneously placing tiles. Some users chose to cooperate in creating the art and later, bots were created to draw automatically on the canvas.

With the collected data, some wonderful visualisation have been created. You can check the original article here and r/place atlas, I just want to repost some of the animations.

Seeing Theory

seeing theory

Seeing Theory: a visual introduction to probability and statistic is a fantastic resource for people who want more a bit more about one of the most useful aspect of our everyday lives.

Probability is everywhere, it governs our everyday lives, is extremely important for even casual decision-making. Still, like Daniel Kahneman pointed out in his wonderful book, we are incredibly bad at estimating statistics and making rational decisions based on data.

To make the situation a little bit better, go play with interactive exhibits on the Seeing Theory website. You would be able to learn more about important statistical concepts: from probability to ANOVA and regression.

Ukrainian political activism – CeDEM16

Yesterday I presented at the CeDEM 2016 conference in the Austrian town of Krems.


It is a great venue to get to know more people working in your field and just make friends.

On CeDEM16 I presented a paper of social media activism in Ukraine. It is kind of a followup to my earlier 2014 paper on similar topic. I’ve got nice feedback and as people are interested in the issue, I decided to share.

You can download my presentation. I included comments with every slide.

The full paper is available in the proceedings of the conference.

Game idea: Conspiracy Mail

Here is my game idea. The email game. The game would look totally like an email app you use daily. You receive and send in-game emails, interacting with varios characters, trying to unravel a conspiracy.

Like real emails, you will receive ConMails in real time, the icon can also have notification badges and new mail counters just like real mail apps.

Literature Review of Couchsurfing Research

The Disclaimer

This is not a comprehensive review (although you’re welcome to add more sources in comments or send me an email). This is also not a real scientific literature review. Some results are contradictory and it is up to you to judge who is right and who is wrong.

This is just a list of academic papers/theses/articles published on the topic of Couchsurfing. I used many of these papers when I was writing my thesis and articles on CS. I hope this little review will help you in your research.

This post is also available in pdf.

The List

(Adamic, Lauterbach, Teng, & Ackerman, 2011) combines data analysis of ratings, a large-scale survey, and in-depth interviews trying to understand the ratings on CS. Many users tend to overrate other members being afraid that they may provide reciprocally negative reference or rating. Negative references are underrepresented (only 1 to 2500 positives). Authors propose rating design that would encourage more balanced feedback.

(Ayers-Greenidge, 2012) explores guest’s motivations to use CS. Author finds that motivation to be a traveller (rather than tourist) is the most important, while initial motivation to save money when travelling is also popular. Author ties trust to the concept of intimate tourism. The similarity is an important factor in selecting possible host.

(Bialski & Batorski, 2010) ties concept of trust in CS to familiarity. Using an online survey of 3000 CS members, and 30 personal interviews, authors outline three stages of the CS experience when the trust emerges: pre-selection of users, website and profile navigation and offline contact. Familiarity plays crucial role in the formation of trust.

Scott Adam’s book

I usually don’t buy such kind of books, but having read (and liked!) other books by Scott Adams, I decided to give it a go.

How to Fail at Almost Everything and Still Win Big, short review.


What I dislike about self-help and business advice books is that often the main idea of any of those books is pretty simple and may be expressed on a single page. However to make the book publishable, authors basically write hundreds of pages repeating one and the same thing over and over again. Unlike the academia…

Podcasts I like

I like listening to podcasts. I listen mostly when driving or at the gym.

Over time I understood that I don’t like the American way of doing podcasts (TED-like, engaging listeners, very emotional). I find them tiring and prefer the British ones.

I am a regular listener of three podcasts that I whole-heartily recommend:

Infinite Monkey Cage (BBC) – incredibly entertaining general science podcast with amazing Brian Cox and Robin Ince as hosts.

Science Weekly (Guardian) – Science news. Helps me to be up to speed with scientific advancements. Leans towards physics/ hard science. Sometimes includes absolutely fascinating interviews.

Friday Night Comedy (BBC) – Recent news discussed by the British comedians. Funny as hell.
