Hello, you're about to listen to a BBC podcast, so I'd like to tell you where you'll find more just like it.

I'm Izzy Lee Poulton, an assistant commissioner for BBC Sounds, which means I'm involved in the whole podcast making process.

Whether that's developing fresh formats or facilitating eye-catching artwork, I helped project manage all the details that make our podcast stand out.

At the BBC, we've got access to storytellers and experts across a huge range of subjects.

It could be psychologists, comedians, celebrities or journalists.

No podcast or day looks the same here.

So no matter what you like, check out BBC Sounds.

There's probably another podcast on there that you're absolutely love.

Thanks for downloading our podcast. You can find out more about TechTent from our web page. Go to

BBCworldservice.com slash TechTent. Hello and welcome to TechTent, your weekly update on all

the hottest news and trends in the technology business.

I'm Rory Kathleen Jones, and this week we have exclusive access to an international police

operation to close call centres in India involved in what's known as computer software service fraud.

We also have a much more positive story from India. We'll hear about their pioneering use of robots in surgery.

And we'll ask whether Facebook's cryptocurrency Libra is in better or worse shape

following Mark Zuckerberg's appearance in front of a congressional committee.

Joining me this week is Su Ping Chang, BBC economics reporter and a big expert on the cryptocurrency scene. Hi, Sue.

Hello, Rory.

Had a busy week? Yes, I had the pleasure of watching that five-hour testimony by Mark Zuckerberg.

Excellent. And a special guest, who I think also was watching that, is Isabella Kaminska from the Financial Times, Alphabille blog.

Also hugely expert on the crypto scene.

How are you, Isabella?
