 Awesome. All right. Welcome. Thank you all for coming. This is the October installment of the Ruby Meetup, and we have three great speakers for you guys as always. If you want, the Wi-Fi password is here, and you want to connect to IDA Labs too. So my name is Anna, and I'm at NUS. I'm doing my PhD there. I study software developers, and I'm helping Winston organize this on occasion. Any first-timers here? That is really cool. Welcome. Please mingle later on as well. Come and introduce yourselves to me. Come and introduce yourselves to Winston, to everyone else. Everyone's really friendly here, and I'm really glad to see so many new folks every time, every Meetup. So thanks guys for coming out. So I also want to take a moment to thank our sponsors. Today's the National Design Center, this beautiful building that we're in. I hope you guys didn't have a lot of trouble finding it. It's this great space, and we're really thankful to be here. Also, the Awesome Pizza is sponsored by Enginyard. So they are our Rockstar food sponsors. And finally, if anyone would like to speak at one of the next Meetups, please let me know. It can be 5, 10 minutes, 15 minutes, whatever you want. You can talk about the last Rails project you've done. You can talk about a gem that maybe you've created. You can talk about a problem that you solved, or if you have a collection of random things that you've sort of figured out and you don't really know what to do with, you can always do five random tips. So we have full talks, and we have also five random tips that we do at the end of the session. So just come talk to me, or get in touch with Winston. These are our emails, and you can also find us on Twitter. By the way, we have a Twitter hashtag, so if you want to take pictures and tweet to people about stuff happening today, you can do that there. Also, every month we now have a Rails Girls Meetup. It is an opportunity for girls, but not just girls, to come and learn Rails. It's a mentor structure, so we're always looking for mentors, and we're always looking for folks to come and join us. It happens every month, so you can watch out for details at the Meetup page, and you can again ask us for more information. So today we have, as I mentioned, three awesome speakers. We have Sasha from PayPal who's going to tell us about PolyBot and how to build stuff in six different programming languages. And we're going to have Gosha, who's going to tell us about contributing to Ruby on Rails. And we also have Joel with five random Ruby tips. And we also have a section for hot picks. So if you've thought of something, or if you've found something that you think is really cool, just jump up here and do a quick lighting presentation. That's also cool. And if you have, or are looking for people, if you're looking to hire folks, come talk to us. Or just come up later on and say a couple of things. I can also put your information later on in the Meetup group if you're looking for folks to hire. All right, so without further ado, can we welcome Sasha, our first speaker? Can we welcome Sasha?
