Are you enjoying our six needle telegraph code? It was a beautiful invention that made telegraphy accessible for non-technical users. Perhaps the beginning of user-friendly design popularising a valuable technology. Anyway, if you haven’t cracked Challenge 9 yet, don’t forget to take a look at the Case Files. You should find what you need there and there is still time …
Speaking of time, don’t forget that the final challenge will be published at 3pm tomorrow. As we remarked the other day, speed of submission matters for this one, but is not the only factor, so pay attention to how you crack it. You might even want to make some notes, as we will be asking some of you to describe your methods when we are assigning prizes!
