How to Compare Two Large CSV Files Without Uploading the Data

Comparing two CSV exports sounds simple until the files get large. A common situation is having an older export and a newer export and wanting to answer four questions: Which rows were added? Which rows were removed? Which existing rows were modified? Which rows are unchanged? A simple row-by-row comparison isn't reliable when the order of rows changes between exports. What you really want is...

Stop Using AI to Write Code, Start Using It to Navigate

The trap of the 'Generate' button When I first started using AI-powered editors like Cursor, I fell into the same trap as everyone else. I would write a prompt, hit generate, and watch a wall of code appear. It felt like a superpower. For the first hour, productivity spiked. By the end of the week, I was spending more time debugging subtle hallucinations than I would have spent writing ...

Zero GPU Cost and 4-Minute Daily Runs — Making Real Rain Fall on a Still Image with ffmpeg displace

A 30-minute ASMR rain video costs me nothing but electricity, and the daily job that builds it dropped from 7–8 minutes to a little over 4. No video-generation model, no GPU rental, no editing. One still image, a physics simulation of raindrops written in Python, and ffmpeg's displace filter. For context on why I built this: in my second year of university I was making ¥100k a month, stacked side...

The Quiet Collapse

There is a particular kind of professional disappearance that does not show up in the unemployment figures. The illustrator still has a desk. The translator still has a website. The session musician still owns a violin. None of them have been fired. None of them have been informed, in any official capacity, that their occupation is being phased out. Their names remain on the same freelance registe...

My checker scored one component compliant and another deviant. Neither had a rule behind it.

This is a follow-up to part four, not a new part. Part four measured my stated routing policy against what actually ran: 425 decisions, 96 deviations, $1,248.13, none of them on the main thread. Then a reader asked what happens when no rule applies. I went to measure it, and the answer was that my checker had been inventing verdicts. In both directions. The question Brian Jin, in the ...

Spec-Driven Development in the Age of AI: OpenSpec vs. GitHub Spec Kit

Originally published on labitcode.com. In the early wave of generative AI, the software industry embraced "vibe coding" — prompting an LLM in an open chat window, hitting apply, and tweaking code until the test suite or browser stopped throwing errors. For weekend prototypes and disposable scripts, vibe coding feels like magic. But when applied to production monoliths, distributed microservices,...

eBPF-Powered Request Tracing in Go Microservices Without Instrumentation Tax

eBPF-Powered Request Tracing in Go Microservices Without Instrumentation Tax Manual OpenTelemetry instrumentation in Go microservices carries a compounding cost: every SDK call site, every context propagation branch, every baggage extraction is code that can drift, be omitted in a hot path, or impose measurable CPU overhead at high RPS. The alternative that has become operationally viab...

The refactor that made every validation build pass without validating anything

Short one. A bug I introduced, caught by reading the diff rather than by any test, and the reason no test could have caught it. The setup A deployment script with a validation mode. On the develop branch it runs with VALIDATE_ONLY=true and is supposed to check everything without writing anything. Original order: workspace = build_workspace() # authenticate, resolve, parse if r...

Write your pages in PHP. Run them on the JVM.

druvu-lib-web 2.0.0 is out: a small Java web framework on Jetty 12 whose template language is PHP. Not "PHP-like" — the 2.0 engine runs real PHP 8 layouts: variables, every control structure, string interpolation, heredocs, includes, arrow functions, and 115 standard functions, with semantics settled by running whole templates against PHP 8 and matching its output byte for byte. There is no PHP ru...

Kubernetes Networking [Level-3: Services]

This is Level 3 of our Kubernetes networking series. In Level 2, we traced how Pod-to-Pod communication actually works — and ended on a serious problem: Pod IPs are dynamic and temporary. An application can't reliably hardcode a Pod IP if that Pod might be replaced at any moment. This article solves that exact problem by introducing one of the most important objects in Kubernetes: the Service. ...

In Level 0, we covered core Linux networking primitives, and in Level 1, we learned how a Pod gets its own network namespace, eth0 interface, and IP address.
