Supabase + Sentry: see what's actually going on in that backend you generated (Sponsor)
Supabase ships your backend fast. Sentry makes sure you know what it's doing in prod 🔎
In this live session, Sentry will take a Supabase app and instrument it end-to-end. Then if something breaks, you know exactly where it is and how to fix it.
Topics include:
- Streaming Supabase logs into Sentry with trace IDs attached, so errors, logs, and traces appear in one view
- Tracing requests from your frontend through Auth and Edge Functions
- Catching N+1 queries and slow database calls automatically
- Using Sentry's Seer and MCP server to let AI agents detect, root-cause, and fix issues without touching the logs manually

Building a fault-tolerant metrics storage system at Airbnb (9 minute read)
To manage 1.3 billion active time series at such a large scale, Airbnb developed a fault-tolerant metrics storage system using shuffle sharding and a multi-cluster architecture for improved resiliency and isolation. This automated solution successfully stabilized data operations and streamlined deployments by treating clusters as disposable components, despite the added complexity of federated querying.
Different Approaches to Debugging Query Performance in Rails (10 minute read)
To maintain a high-quality user experience, Rails developers must systematically address slow database queries using a combination of built-in features, third-party gems like Bullet, and database-specific monitoring tools. This optimization process requires an iterative cycle of identification, analysis, and continuous production monitoring to ensure long-term performance stability.
Learnings from conducting ~1,000 interviews at Amazon (35 minute read)
Behavioral interviews are often the deciding factor in securing software engineering roles because they assess a candidate's cultural fit and collaboration skills. While technical proficiency is mandatory, clear storytelling and thorough company research are necessary for demonstrating how a candidate navigates challenges and works within a team.
I don't want your PRs anymore (5 minute read)
External PRs are no longer being accepted for certain projects due to the efficiency of LLMs in generating code. Future contributions should focus on high-value tasks such as providing feedback, discussing architectural designs, or reporting bugs.

Tim Cook's Impeccable Timing (17 minute read)
Tim Cook's tenure as Apple CEO drove unprecedented financial growth by scaling Apple's products and expanding services, though it faced criticism for prioritizing short-term gains and relying heavily on Chinese manufacturing. As he transitions to Executive Chairman, Cook leaves a legacy of large market value. His successor must address the long-term strategic challenges in AI and supply chain sustainability.
Inside GitHub's Fake Star Economy (15 minute read)
A widespread fake star economy on GitHub involves startups purchasing millions of fake stars to artificially inflate repository popularity and attract venture capital funding, which relies on star counts as a key signal. This persistent manipulation can be detected by analyzing metrics like low fork-to-star ratios. Combating the deception requires investors to adopt more robust metrics and for GitHub to implement structural changes.
My practitioner view of program analysis (4 minute read)
"Correct" software is code aligned with the collective intent and understanding of all stakeholders, necessitating a bridge over the semantic gap where code fails to communicate its underlying concepts. Overcoming this requires program analysis, particularly static analysis, as a tool to inspect a program's capabilities without execution and create the shared understanding essential for truly correct software.
