Yesterday, I celebrated the 25th anniversary of Wikipedia with the Wikipedia Bus at the Stadtbibliothek Stuttgart. With the Cluster of Excellence SimTech of the University of Stuttgart (@Uni_Stuttgart), we prepared some activities to explain how knowledge is created, verified, and made accessible to everyone.

I finally launched Frases, a game to play from the #Fediverse. Follow one of the actors, and you will receive sentences to guess. Why these countries and languages? I plan to cover many Spanish-speaking countries in the Americas. I just picked some to start, plus countries where I have lived. https://frases.degu.cl

Today I launched a game called #FrasesGame @frases, which consists of guessing daily sentences (like Wordle). It supports #ActivityPub agents for communication. Like @ladeldiacl, these sentences are region-specific. However, I created different actors for #Chile, #Argentina, #CostaRica, #Deutschland #Germany, #Danmark #Denmark, and #English. The game is open to try! #FediGames Website: https://frases.degu.cl/

RE: https://frases.degu.cl/results/DB77MMzrR3FLteqKgbeMIg Esta es una prueba de que ahora se puede citar una nota de #FrasesGame. Para que los usuarios de Mastodon 4.3+ pudieran citar los resultados del juego, fue necesario agregar el campo interactionPolicy.canQuote.automaticApproval = Public (usando el namespace de GoToSocial según FEP-044f) a las notas ActivityPub, ya que Mastodon interpreta la ausencia de este campo como &quot;nadie puede citar esta publicación&quot;.

Two days ago, Gabriel Boric, president of #Chile, reopened the Talca-Constitución branch line, which was damaged during the 2010 earthquake. @Ayenkantun and I took that trip in February 2009. This is a photo from our journey. #Trains #Memories #Throwback
