This is the episode where everything that can go wrong, does go wrong.

For starters, it's being released six days late because the audio file was incomplete. Then, there was no live stream of this episode because no matter where we positioned the router, it did not play ball. And there isn't even a pre-recorded video version of the episode because technology clearly hates us.

Still, we salvaged what we could for this episode and most of it is here for your listening pleasure! This week, after spending days on trains where internal temperatures were approaching 40 degrees Celcius, we ask why the London Underground is still not airconditioned, or even ventilated, in this day and age? It turns out the answer is entirely to do with a major technological limitation when it comes to cooling.

We also look at the scandal-ridden omnishambles that is Uber, after co-founder Travis Kalanick resigned as chief executive after a slew of scandals at the 'ride sharing' (ahem, taxi) company. What does the future hold for Travis and Uber, and will it be the same company without him?

Our techno dinosaur is also wondering what she can do to ensure she's on the right side of the new EU rules regarding mobile roaming when she goes on holiday.

Recorded on 22 June 2017 at Park Town Studios, London, England. Released many days later. All rights reserved.
