 So the next one seems to be something on shortened number generators, or something which is coming by the word PRG. You would think. So, hi, I'm Pavel. So, I recently joined the Computer Science Department at the Charles University in Prague. I'm interested in theoretical cryptography. So, like, to use the classification of one of the previous speakers, I'm more interested in the practical cryptography, okay? So, like, I want real improvements. And I want to share with you a story of a cryptographer who just came to Prague and made me do some product placement. So, before coming to Prague, I knew that Czech Republic is very strong in some areas of theoretical computer science. Like, proof complexity, especially computational complexity, computational geometry. And, well, little did I know. So, I came to Prague. It's this beautiful city. So, over the first few months, I was just looking around all the monuments. And then I noticed that the TCS community is very cocky. They started marking the territory. So, you go around and you see this. And it's all around Prague. You wouldn't believe it. Like, on my house, there is a TCS march. So, like, wherever you go, TCS, TCS, TCS. So, yeah, like, the Prague community is very cool. Well, how about the crypto in Prague? Historically, we're very strong. Like, key management that we've been doing since the medieval times. As a child, you will learn that the Czech crown jewels are stored at the Prague Castle. So, these are the jewels. And they are stored at the Prague Castle, locked for most of the year. And they're brought out on very special occasions. And for that purpose, seven people who share each have a key. They need to come and unlock the room and bring out the jewels. So, like, pretty good stuff. A little bit old technology, but we can work on it. And I was thinking, like, is this just, like, the past? And so, what happened? Like, the computer science department is somewhere over there. It's, like, in the historical city center. And once going for lunch, I noticed that there's, like, a lot of crypto enthusiasts in Prague. Like, I go and there's, like, hundreds of people wearing t-shirts. I love PRG. And I thought, wow, that's great. Like, the community, like, the spirit is really high here. But after a few days, somebody told me that it might be because PRG is the acronym of the Prague Airport. And, yeah, what can you do? But merchandise, we can use it too. It's totally fine. So, now for the product placement. Well, I'm currently looking for a post-doc. And I'll be happy to talk with anybody who might be interested. So if you want to come to Prague to work with me and get some cool merchandise, just get in touch. Thanks.
