You need a fundamental shift in how you operate
Getting to staff engineer
4 minutes by Nitin Dhar
Advancing from Senior to Staff Engineer requires a fundamental shift in how you operate, not just doing good work. In this post Nitin suggests to focus on making others better, owning organizational problems rather than codebases, making your behind-the-scenes work visible, and becoming a force-multiplier who unblocks teams. The role demands leading without authority, strategically saying "no," and effectively communicating with leadership—essentially treating it as a different job, not just a reward for excellence in your current position.
Cut microservices testing infrastructure cost by 90% and speed up testing cycles 10x
sponsored by Signadot
Duplicating microservice environments for testing creates unsustainable costs and operational complexity. Instead, modern engineering teams are adopting application-layer isolation with Signadot’s "sandboxes" - sharing underlying infrastructure while maintaining isolation through smart request routing. This approach cuts infrastructure costs by over 90% while enabling 10x faster testing cycles and boosting developer productivity. Try it for free today.

How projects fail at large tech companies
8 minutes by Sean Goedecke
Projects at large tech companies fail for various reasons. Sean discusses the main reasons like being doomed from the start due to over-ambition or technical impossibility, lacking sustained political support, encountering bad luck like unpredictable incidents or user disinterest, suffering from incompetent execution, or experiencing "death by a thousand cuts" where good ideas are diluted by too many stakeholders adding requirements.
On the road to your own vector db
8 minutes by Doug Turnbull
Vector search helps find similar items by comparing vector embeddings, and Doug demonstrates a basic graph-based approach to nearest neighbor search with code examples. He highlights the limitations of simple grid-based approaches and previews how advanced concepts like quantization, clustering, and hierarchical structures can improve vector search efficiency.
