Documentation of digital experiments, engineering rants, and the pursuit of a perfectly optimized brutalist web.
Learn the Barrel Pattern — how to use index.ts barrel files to simplify imports, reduce path complexity, set up tsconfig path aliases, avoid circular dependencies, and keep JavaScript and TypeScript projects maintainable.
Deep dive into how Node.js require() resolves module paths, checks the module cache, wraps code in closures, executes modules, returns exports — plus ESM vs CommonJS comparison, dynamic import(), and circular dependency behavior.
Learn how to create, link, and publish Go modules — build a reusable math utilities module, use go mod init, the replace directive, go workspaces, semantic versioning, and publish to pkg.go.dev.
Master Go's fmt.Sprintf() with format verbs (%v, %s, %d, %q, %b, %x), width and padding, zero-padding, argument indexing, fmt.Fprintf for HTTP responses, fmt.Sscanf for parsing, and common pitfall fixes.
Explore every Go data type — bool, string, int, float, byte, rune, arrays, slices, maps, pointers, and interfaces — with practical examples, type conversion, and best practices for Go beginners.
A deep dive into the Go runtime — automatic memory management, concurrent garbage collection, GOGC tuning, goroutines, the M:N work-stealing scheduler, goroutine leak detection, and profiling with pprof.
Step-by-step guide to installing Go (Golang) on Linux, macOS, and Windows. Set up your PATH, configure VS Code, verify your installation, understand GOPATH vs GOROOT, and fix common installation errors.
Understand JavaScript type coercion — implicit conversions, explicit methods like Number(), String(), Boolean(), the abstract equality algorithm, object-to-primitive coercion, and when to use each.
Quick commands to find and kill processes blocking a port on macOS, Linux, and Windows — using lsof, kill, fuser, pkill, netstat, and taskkill with step-by-step instructions and troubleshooting tips.
