In this talk titled 'How to Hijack', held at the wroc_love.rb 2019 conference, Dávid Halász discusses the complex concepts of smuggling, hijacking, and proxying in non-blocking disorder sockets using Ruby on Rails and Rack.

Key points include: 
- **Introduction to Speaker and Context**: Dávid, from Hungary and now residing in Brno, Czech Republic, works for Red Hat and focuses on hybrid cloud infrastructure management with ManageIQ, emphasizing its Ruby on Rails architecture. 
- **Browser Remote Consoles**: Explained the implementation of remote desktop sessions via browsers using a VNC endpoint to access virtual machines, leveraging WebSockets for bidirectional data transfer. 
- **Sockets and Buffering**: Introduced programming sockets, the importance of buffering in I/O operations, and the challenges of blocking I/O, which can lead to endless loops in proxy implementations. 
- **Non-blocking I/O**: Discussed the benefits of non-blocking I/O methods and how they can be utilized to avoid complications when handling multiple sockets, including the concept of 'bouncing select'. 
- **Epoll and socket handling**: Covered improvements in socket handling in Linux with epoll and how to manage readiness of sockets effectively, as well as the creation of Ruby wrappers for this mechanism. 
- **WebSocket Management and Hijacking**: Explored how WebSockets facilitate persistent connections and the technique of socket hijacking to manage interactions with underlying VNC connections while maintaining server efficiency. 
- **TCP Smuggling**: Proposed generating TCP connections that could efficiently handle data and emphasized the necessity of a browser plugin due to limitations imposed by browser sandboxes. 
- **Demonstration of Architecture**: Dávid showcased a live demo of a VNC session running in a containerized environment, illustrating how connections to VMs can be established and managed effectively, utilizing simple server structures similar to Rack.

The conclusion highlighted that although the architecture utilizes a server, browser plugin, and client app, further refinements are necessary before it can be considered production-ready. The audience was engaged through a Q&A session, clarifying technical queries about the socket translations and operational efficiencies.

Overall, the talk provided an insightful examination of using Ruby for advanced network operations, making a case for innovative solutions in hybrid cloud environments.
