Implementing TCP in Rust (part 1) Video

In this stream, we started implementing the ubiquitous TCP protocol that underlies much of the traffic on the internet! In particular, we followed RFC 793 — https://tools.ietf.org/html/rfc793 — which describes the original protocol, with the goal of being able to set up and tear down a connection with a "real" TCP stack at the other end (netcat in particular). We're writing it using a user-space networking interface (see https://www.kernel.org/doc/Documentation/networking/tuntap.txt and the Rust bindings at https://docs.rs/tun-tap/).

We got decently far, and are now able to both establish an incoming TCP connection (i.e., perform the TCP three-way handshake) and terminate the connection cleanly. You can find the current code at https://github.com/jonhoo/rust-tcp. There's still a long way to go though, as we still need to add support for data segments, retransmissions, and timers; so that's what we'll cover in the next stream! Eventually, we will also want to implement RFC 1122 — https://tools.ietf.org/html/rfc1122 — which lays out a number of further enhancements that must be made in order to interoperate nicely on the internet. This is also discussed in RFC 7414: https://tools.ietf.org/html/rfc7414#section-2, which we're also aiming to support.

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.

About YouTube 📺

YouTube, an American video-sharing website based in San Bruno, California, offers a diverse range of user-generated and corporate media content. 🌟

Content and Users 🎵

Users can upload, view, rate, share, and comment on videos, with content spanning video clips, music videos, live streams, and more.

While most content is uploaded by individuals, media corporations like CBS and the BBC also contribute. Unregistered users can watch videos, while registered users enjoy additional privileges such as uploading unlimited videos and adding comments.

Monetization and Impact 🤑

YouTube and creators earn revenue through Google AdSense, with most videos free to view. Premium channels and subscription services like YouTube Music and YouTube Premium offer ad-free streaming.

As of February 2017, over 400 hours of content were uploaded to YouTube every minute, with the site ranking as the second-most popular globally. By May 2019, this figure exceeded 500 hours per minute. 📈
