Power of the Log:LSM & Append Only Data Structures

This talk is about the beauty of sequential access and append only data structures. We'll do this in the context of a little known paper entitled “Log Structured Merge Trees”. LSM describes a surprisingly counterintuitive approach to storing and accessing data in a sequential fashion. It came to prominence in Google's Big Table paper and today, the use of Logs, LSM and append only data structures drive many of the world's most influential storage systems: Cassandra, HBase, RocksDB, Kafka and more. Finally we'll look at how the beauty of sequential access goes beyond database internals, right through to how applications communicate, share data and scale.

Property-Based Testing In Practice

Testing is a cornerstone of modern software development. It provides us with a safety net against bugs and regressions – without testing, it would be impossible to write large-scale applications. The traditional approach to testing relies on hard-coded examples: fire some specific inputs into...

Assuring Crypto Code with Automated Reasoning

Bugs in software are ubiquitous, but the impact of these bugs can vary widely. Sometimes they are largely benign, and at other times they can have catastrophic effects. Bugs in cryptographic software tend to be especially serious. To add to that, cryptographic algorithms are difficult to design...
