Decoding the mechanics of high-performance systems.
A Minimal Note-Taking System for Thoughts, Ideas, Questions, and Actions
Practical, unsentimental steps to lock down your passwords, devices, and online identity before someone else owns them.
Running Outline VPN over HTTPS (port 443) to slip past censorship. Learn how to blend in with HTTPS traffic and what it actually takes to stay invisible.
A no-fluff, step-by-step guide for software engineers dealing with massive Git merge conflicts during migrations or long-lived branches. Includes real anecdotes and ASCII diagrams.
A deep dive into Facebook's memcache architecture and the hard lessons it teaches about real-world system design, performance, and failure.
Bitmasking is one of those computer science tricks that feels like wizardry, until you realize it's just some clever shifting and binary math. This blog explores the idea, shows how we use it in Go, and why it's surprisingly useful when working with databases like Couchbase.
When working with Docker, persistent data is often stored in volumes. Unlike container filesystems, volumes survive restarts and recreations. But what if you need to move this data from one machine to another? Here's a quick and reliable way to back up a Docker volume on one computer and restore it on another.
Understanding different types of software testing is crucial for delivering a reliable application. Smoke Testing checks basic stability after a new build, while Sanity Testing verifies specific bug fixes or minor updates. Functional Testing ensures that features work as expected based on business requirements. Regression Testing prevents new changes from breaking existing functionality. End-to-End (E2E) Testing simulates real-world user workflows, and Performance Testing checks system speed, load handling capacity, and responsiveness. Implementing these (some or all) test types helps maintain software quality and prevent critical failures.
Tools I Use on My MacAs a new Mac user, it has been a tough journey getting used to limitations of macOS compare to linux based os. I rely on a set of carefully chosen tools to improve productivity, streamline workflows, and make my overall experience less frustrating. Here’s a look at top 20 essential apps I use daily: System & UI Enhancements1. Scroll ReverserAllows me to reverse the scrolling direction for trackpads and mice independently, making navigation more intuitive.
In Go, method receivers determine whether a method acts on a copy of a value or a reference to it. This choice isn't just about performance; it affects correctness and behavior, especially when dealing with synchronization primitives (mutex, wait group, etc), slices, and embedded types.
Senior software engineer working mostly in Go. I build backend systems and AI applications: feeds, search, LLMs, the infrastructure underneath. When something doesn't make sense, I pull it apart until it does. This blog is where I write that up.
