Exploring Container Mechanisms Through the Story of a Syscall - Alban Crequy, Kinvolk (Intermediate Skill Level)
Alban will explore different container mechanisms on Linux by following a simple example: what is happening when an application in a Kubernetes pod performs a syscall such as “open()”? In particular, he will go through the following subsystems: SELinux LSM, seccomp-bpf, capabilities, overlayfs and copy-on-write, and path lookups in the container mount namespace. He will see how it interacts with different pod configurations.
About Alban
Originally from France, Alban currently lives in Berlin where he is a CTO & co-founder at Kinvolk, a software engineering team focused on building foundational Linux technologies for the cloud. He is a contributor to rkt, a container runtime for Linux, Weave Scope, a container visualization & monitoring tool, and is actively working on BPF-related projects. Before falling into containers, Alban worked on various projects core to modern Linux; kernel IPC and storage, dbus performance and security, etc. His current technical interests revolve around networking, security, systemd and containers at the lower-levels of the system. Alban previously gave talks at several conferences including FOSDEM, Linux Plumbers, IO Visor Summit, Kubecon and LinuxCons/OSSummit.

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. 📈
