In this fourth Crust of Rust video, we cover smart pointers and interior mutability, by re-implementing the Cell, RefCell, and Rc types from the standard library. As part of that, we cover when those types are useful, how they work, and what the equivalent thread-safe versions of these types are. In the process, we go over some of the finer details of Rust's ownership model, and the UnsafeCell type. We also dive briefly into the Drop Check rabbit hole (https://doc.rust-lang.org/nightly/nomicon/dropck.html) before coming back up for air. This is definitely a more technically advanced stream than some of the earlier ones, and may be a little harder to follow. I apologize for that in advance! Please do leave questions here or on Discord and I'll try to help explain what's going on.

This presentation was recorded at GOTO Amsterdam 2024. #GOTOcon #GOTOams https://gotoams.nl Heinrich Hartmann - Head of Reliability Engineering at Zalando SE @HeinrichHartmann RESOURCES https://twitter.com/heinrichhartman https://github.com/HeinrichHartmann https://www.linkedin.com/in/heinrich-hartmann-b524a076 https://heinrichhartmann.com ABSTRACT We present Zalando's approach to engineering reliability from a very small to a very large scale, and touch on both technological and human angles. With over 50M customers across 23 countries, Zalando operates one of the largest eCommerce platforms worldwide. Achieving a reliable customer experience requires the intricate collaboration of over 3000 applications and more than 2000 software engineers who constantly seek to improve and extend product capabilities. In the talk we will walk you through the best practices Zalando has arrived to consistently achieve high levels of reliability. • We will start with a simple stand-alone application and cover best practices for instrumentation, monitoring and alerting. • We continue the journey to products that span multiple applications which are operated by different teams. At this scale methods like tracing and incident management become important. • Finally we will present technologies and processes which are used to steer reliability on the company level. Here WORM Cascades and Risk Management have proven highly effective.

DuckDB has full SQL support and can natively read/write formats such as CSV, Parquet, and JSON. It is built according to a modern system architecture, which allows running complex queries in parallel and spilling to disk for larger-than-memory workloads. This talk discusses DuckDB's key building blocks and demonstrates how it can handle hundreds of GBs of data on a laptop, or terabytes of data on a single server.
