As Europe sees a wave of cyber-attacks on commercial fridges, we investigate how everyday devices are vulnerable. A listener tells us about his experiences as a moderator for a pornography service. Plus, how the US Midterm elections affect tech around the world. And tech time troubles with another listener.

Independent journalists around the world are falling victim to fake copyright strikes against their content on social media, especially when their stories are critical of powerful figures. Then we look at how AI has been brought into safety on US railroads. Plus, the tech which helps a live orchestra keep in time with screenings of Lord of the Rings.

A week ago, few outside of the tech world had heard of PHP. Now, after vulnerabilities were discovered, it’s an acronym many more of us are familiar with. With the help of insiders, we tell the story of the PHP crisis. Plus, Tech Life speaks to a comedian whose jokes were taken and retold by an AI avatar – which then went on to get millions of views online. And after we visited the UK’s national supercomputer a few weeks back, we answer some of your questions with the centre’s director.

Where should data centres be built? We talk to an entrepreneur hoping to build a virtual data centre in space, by using computing power that's already up there - in satellites.

Also this week: A Facebook whistleblower, whose story inspired a new movie, talks to us about social media and AI. And could rotating sails help to reduce container ship exhaust pollution?

What exactly is a supercomputer for? How does it work? And who gets to use it? Tech Life spends the day at the UK’s national supercomputer to get the answers. We get a rare tour of one of the most powerful computers in the country, and speak to scientists who have access to the computer about how it helps them with their research.

Security researchers have got an AI model to break its own rules and give advice on terrorist attacks and assassinations. They talk to Tech Life about their findings. Plus, indie game developer Jonathan Blow on why he spent 10 years inventing his own coding language and game engine for his newest release. And Shiona McCallum takes us through the latest in birth tech.

AI is developing rapidly. What should parents and children make of it all? And how can young people navigate school and future careers when AI is becoming increasingly important? We speak to an expert who has written a new book about these issues.

Also this week: we find out how one piece of health tech is helping scientists uncover disease-fighting data in menstrual blood. And satellite imaging is used by conservationists in Indonesia to protect the habitat of a rare species of orangutan.

Lots of people make a living from social media posts. But some have been targeted by an international extortion scheme. It involves a flood of false copyright infringement claims. It only stops if the extorter is paid. Imran Rahman-Jones has the story.

Also this week: could AI help to spot wrong-way driving on Ireland's major roads? And we bring you the latest titles and tech on show at Gamescom in Germany.

English is the most widely-used language online. Internet material helps to train AI tools. So where does that leave people whose native language barely features on the web? We find out about a project helping AI to work in more of the world’s languages.

Also this week: regulating tech might sound about as appealing as a trip to the dentist. But, like your check-up, it is important. With Europe and the United States taking different approaches, we’ll ask who gets to set the rules, and what that means for the rest of us. And there’s a growing range of technology aimed at older people. We’ll look at some of the products out there, and ask how useful they really are.
