Synchronised Retries Turn a Blip Into an Outage

I remember sitting in a dimly lit server room during my first year in industry, watching a dashboard turn a violent, pulsing shade of red while a senior engineer stared blankly at a screen. We had implemented a “robust” error-handling…

The Chain Rule Applied Very Carefully and Very Often

I spent three years in academia watching brilliant students stare at chain-rule derivations until their eyes glazed over, all because they were taught that backpropagation is some mystical, impenetrable sorcery. I’ve seen too many tutorials treat it like a black…

The Algorithm Behind Every Diff You Have Ever Read

I remember sitting in a windowless grad lab at 2:00 AM, staring at a stack of textbook proofs for the longest common subsequence that felt more like religious liturgy than actual engineering. The textbooks always presented the solution as this…

Normalise Until It Hurts, Denormalise Until It Works

I remember sitting in a windowless server room during my first industry research role, staring at a distributed database that was buckling under its own weight. We hadn’t failed because our hardware was weak or our code was sloppy; we…

A Stack of Simple Functions That Becomes a Complicated One

I spent three years in academia watching brilliant researchers build increasingly baroque mathematical proofs for things that could be explained with a simple diagram and a bit of intuition. It frustrates me how often people treat neural network fundamentals as…

Stop Calling the Service That Is Already Down

I was elbow-deep in the guts of a 1950s Brunsviga mechanical calculator last Tuesday when the smell of ozone hit me—that sharp, metallic tang that tells you something has gone wrong far more effectively than any digital warning light ever…

Cite the Work You Used, Not the Work You Skimmed

I remember sitting in a windowless lab three years ago, staring at a distributed systems paper that claimed to have solved a consensus problem we were currently drowning in. I spent six hours tracing their logic, only to realize the…

Tables for Precision, Charts for Comparison

I remember sitting in a windowless conference room during my first year as a research engineer, watching a senior architect present a slide deck that was essentially a crime scene of data visualization. He had taken a perfectly clean set…
