After a four-decade career of toggling back and forth between big and small, Lightspark SVP of Engineering James Everingham shares his playbook for scaling down your leadership as you go from an org of hundreds or thousands to a handful of direct reports.

When Good Correlation is Not Enough
Choosing to use a block range index (BRIN) to query a field with high correlation is a no-brainer for the optimizer. However, under some easily reproducible circumstances, a BRIN index can result in significantly slower execution even when the indexed field has very high correlation. This article describes how using a BRIN index in presumably "ideal circumstances" can result in degraded performance, and suggest a recent new feature of PostgreSQL as a remedy.

Nice to meet you, mondayDB architecture
mondayDB is the new in-house data engine we crafted at monday.com. It shifted the entire organization’s data paradigm, and is by far the most challenging and rewarding project I’ve had the pleasure of working on.

Lessons Learned Running Presto At Meta Scale
Presto is a free, open source SQL query engine. We’ve been using it at Meta for the past ten years, and learned a lot while doing so. Running anything at scale - tools, processes, services - takes problem solving to overcome unexpected challenges. Here are four things we learned while scaling up Presto to Meta scale, and some advice if you’re interested in running your own queries at scale.

AI Safety – Full Course from Safe.AI on Machine Learning & Ethics
ML systems are rapidly increasing in size, are acquiring new capabilities, and are increasingly deployed in high-stakes settings. As with other powerful technologies, safety for ML should be a leading research priority. In this course we’ll discuss how researchers can shape the process that will lead to strong AI systems and steer that process in a safer direction. We’ll cover various technical topics to reduce existential risks (X-Risks) from strong AI, namely withstanding hazards (“Robustness”), identifying hazards (“Monitoring”), reducing inherent ML system hazards (“Alignment”), and reducing systemic hazards (“Systemic Safety”). At the end, we will zoom out and discuss additional abstract existential hazards and discuss how to increase safety without unintended side effects.
