RAII: Compile-Time Memory Management in C++ and Rust

Published: 11 October 2022
Tags: rust, compiler

Jimmy Hartzell discusses how Rust's RAII-centric compile-time memory management system compares to other run-time reference counting and garbage-collection technologies.
Some highlights:

  • RAII was originally designed to solve the problem of managing resources, and while it has some deficits, C++ has added features like move semantics and opt-in reference counting that help to close the gap
  • The biggest downside of the above memory management techniques is the performance implications and handling of cyclic data structures

Reducing Logging Cost by Two Orders of Magnitude using CLP

Published: 29 September 2022
Tags: big data, optimization

Jack (Yu) Luo and Devesh Agrawal describe how Uber integrated CLP into their logging library in order to save storage, memory, and disk/network bandwidth.
Some highlights:

  • CLP achieves a 169x compression ratio on their log data, which has allowed Uber to retain all logs at a fraction of the cost
  • Logs compressed with CLP can be searched without decompression

Mathew Duggan presents the dangers of adopting new technology without due diligence. Mathew specifically focuses on containers, explaining how they're frequently used incorrectly from a security and best practice point of view.
Some highlights:

  • Don't run apps in containers as root
  • If you're using Docker in production, you should really understand how permissions work on the host OS
  • Use Docker Bench for Security for scanning containers to check if they're made securely and get recommendations if not
  • k8s is a bad choice for most businesses
