Topic: PostgreSQL

This presentation focuses on the finer points of NULLs in PostgreSQL as well as corner cases.  We will start with an introduction to NULLs and three-valued logic and a quick overview of the common NULL traps that everyone tends to fall for.  Then we will dive in to corner cases and what they tell us about NULL handling in general.  We will also cover a few cases where proper understanding of NULL handling makes some problems much easier.

Within the university setting, Linux is treated more as a burdening task than a helpful tool. In this presentation, we will explore the synergy that is Linux, Nix, and Computer Engineering. With these tools, we can enable engineers to use tools that work within the same environment as the developer before going out into the big world.

Topic: Security

Security policies are critical to mitigating the challenges and issues facing security departments and ensuring compliance with regulatory requirements. This talk highlights the importance of security policies in addressing security issues and compliance failures, and offers strategies for creating, implementing, and enforcing effective security policies that align with industry best practices and regulatory requirements.

We'll discuss the challenges we faced when running Chef in the cloud: juggling build time v/s runtime dependencies, attempting to test continuously moving updates, sharing cookbooks across different deployment environments, and being constrained to CentOS.

Later, we’ll reveal how we turned these challenges around by adopting an immutable instance philosophy: managing instance lifecycle via CI/CD pipelines, relying on build time testing, reducing chef runtime footprint, and making critical host level infrastructure portable by moving it to docker containers.

Topic: Observability

OpenTelemetry is today's defacto standard for distributed tracing. It's collector is used by everyone in varied configurations to accept spans. However, tuning the collector takes time and a lot of energy to get right. In this talk we discuss what are the steps we took to tune the collector, what our final configuration was and how we pivoted the platform to a more optimal architecture based on what we learned. 


This talk provides a reference implementation for tracing at scale. Something we don't hear enough about.

The data available about open source projects can feel like a tsunami with wave after wave of data that can feel overwhelming. But there are ways to make this more manageable by finding and focusing on the metrics that matter the most for you. This talk focuses on tips and techniques for making sense of those waves of data using collections of metrics to result in actionable insights about your open source software.

There are two main schools in AI: physicalist and symbolic. The 1st one focuses on reproducing the neurons to create intelligence. It is today known as machine learning and people often consider it as synonym to AI. It is based on satistical pattern recognition has produced amazing results. The 2nd one focuses on human cognition emergence through logics. Less known because the existing approaches are centralized and cannot handle mutiple reasoning types. Distributed Reasoning AI solves it and has been succesfully applied for drug R&D where understanding the causal level is crucial.
