[Live on May 6] Stop babysitting your agents
Agents can generate code. Getting it right for your system is the hard part. More MCPs solve access but not understanding. Join us for a FREE webinar on May 6 to see how to give agents exactly what they need, so they generate mergeable code the first time.

Learn how audio fingerprinting and a connect-the-dots trick lets Shazam identify a song in seconds.
This post is about optimizing an extremely simple AST-walking interpreter for a dynamic language called Zef that the author created for fun to the point where it is competitive with the likes of Lua, QuickJS, and CPython.
Meta has developed a scalable framework to migrate its global infrastructure to Post-Quantum Cryptography (PQC), prioritizing hybrid key exchange to maintain classical security while defending against future quantum threats. The migration highlights the necessity of crypto-agility and automated testing, as varying PQC public key sizes require significant adjustments to network protocols and hardware performance.
Introducing ggsql, a grammar of graphics for SQL that lets you describe visualizations directly inside SQL queries
The article argues that builders and similar APIs are finite state machines, and the best design prevents impossible transitions by making illegal states unrepresentable. The key insight is that static type systems can enforce these guarantees at compile time, while dynamic languages usually rely on runtime validation.
Since the premiere of Chris Rock: Selective Outrage, Netflix has scaled its live streaming capacity from one show per month to over nine shows in a single day. This growth is driven by specialized Live Operations teams that manage the technical infrastructure required to support tens of millions of concurrent viewers globally.
Two concurrent sessions, same page, different answers. An interactive tour of xmin, xmax, snapshots, and the visibility rules that decide what PostgreSQL lets you see.
How leadership focus evolves around What, How, and Why.
The Glyph protocol introduces a way for terminal emulators to render rich, high-resolution graphics and interactive UI elements by transmitting data over standard escape sequences. It aims to replace fragmented, legacy hacks with a unified standard that allows CLI tools to display everything from complex vector icons to full-screen layouts without sacrificing performance.
How Airbnb team built a storage system that ingests 50 million samples per second and stores 2.5 petabytes of logical time series data.
Watch, Listen
Kubernetes operators often process custom resources sequentially by default, creating queue delays where later objects wait minutes before reconciliation even begins. Using MaxConcurrentReconciles enables parallel workers, turning the bottleneck from waiting in line into a tunable throughput problem based on workload and cluster capacity.
Take your creative web development to the next level by building an interactive 3D cozy cafe portfolio from scratch using Blender and Three.js. This course covers professional workflows, covering everything from subdivision modeling and texture painting to implementing a robust singleton architecture in your code.
