The beginning of May, weeks 139 and 140 of the DCRC, marks a transition into assessment and recognising the efforts of our students and pushing forward with nurturing the seeds of new research. We have PhD students moving into the final stages of writing up and moving towards examination, as well as undergraduate end of year shows. 139 is a prime number and the number of one of the ports used as part of the Microsoft Windows NETBIOS file sharing system. 140 is, of course, the character limit of a post on Twitter - based on the original calculation of an SMS message limit at 140 8-bit characters.
