EMDC first years were either in Portugal or Spain, where we all spent the 3rd semester in KTH/Sweden. For the forth semester, some of us came back to our host countries (Portugal or Spain), some stayed in Sweden (mostly just with KTH, while some went on to do an industrial internship at Sportify), and some did an internship in a third European country (such as France, Germany, or Switzerland). I came back to ULisboa/Portugal, making it ULisboa/Portugal -> KTH/Sweden -> ULisboa/Portugal for my MSc. That also means, I was one of the few with minimal diverse experiences during my MSc, as I spent time in just two countries where many of us were in three countries. I compensated for this lack of migrations during my Ph.D., with my 3 international research internships (Croatia, USA, and Saudi Arabia) that spanned continents, in addition to my two universities (ULisboa/Portugal and UCLouvain/Belgium). I started my affiliation with ULisboa in 2012 August and spent 7 years doing my MSc and Ph.D., making it the longest university of my life so far, even longer than my 5 years (so far) at Emory University. #WeAreTécnico!

Docker: failed to create LLB definition
I was getting this weird error on Docker for the same container that was building fine just minutes go.
$ docker build -t hummingbird:1.0.0 .

Turned out, this error can appear when the disk is full (observed in MacOS), with no issue from the built container image itself. How did the desk get full within a few minutes? Of course, by building a few Docker containers and them remaining in cache. Deleting some files to get some storage space and restarting Docker made the build succeed again.
