Technical writing on models, systems, and software by Serendeep Rudraraju.
Mechanistic interpretability was built for softmax transformers. SSMs, diffusion LMs, and sparse MoE each dissolved one of its assumptions. Here's what that actually cost.
A city shipped a 'homegrown' AI; subtraction proved most of it was someone else's. The toolkit for catching model fraud, and its honest limits.
Bloom filters and their descendants trade a bounded, one-sided, tunable error for a space collapse exact structures can't match. The whole family, with the math.
Part 2 of building cratemind: the unglamorous 80%, tempo that lies by an octave, key from 1990s music theory, and a downloader that never quietly loses a track.
Spotify deleted the BPM API and underground techno has no genre tag anywhere, so I stopped looking the genre up and started computing it from the audio.
The same model behaves like a genius on small tasks and a goldfish on big ones. The bottleneck isn't intelligence. It's memory, and memory lives in the harness.
HiPPO's polynomial-projection idea is the through-line from S4 to Mamba-3 to HiSS. And it argues that long-context LLMs and long-context prediction are not the same problem.
An EBM finally crossed 800M parameters without collapsing. Nobody has independently reproduced the 35% scaling claim. Both halves matter.
No major AI model meets the open source definition. Here's who's faking it, who benefits, and why the strongest argument against caring is uncomfortably real.
A practitioner's guide to Mamba and State Space Models — how selective state spaces achieve linear scaling, when to use SSMs vs Transformers vs hybrids, and production-ready models.
VLA models give robots the ability to see, parse language, and execute physical actions through a single architecture. This post covers how they work, what shipped in 2025, and where the limitations are.
A tutorial on building a timezone-aware scheduler with React and the Temporal API, covering why Date fails at serious datetime work and how Temporal's type system prevents those bugs.
Your fitness tracker is selling you out. The open source alternatives that aren't.
The 2,500-year history of formal grammar, from Pāṇini's Sanskrit rules to BNF, and why someone proposed renaming it 'Panini-Backus Form' in 1967.
What if your AI worked offline, kept your secrets, and actually remembered you, without ever flinching at a spotty network? This post moves past the "API-everywhere" playbook. It lays out theory for a...
Starting a new app, most of us wire up the backend before we even sketch the core screens -- then hope our offline mode just works later. It rarely does.
Starting a new Flutter project can get messy, fast. My first starter template turned into a cluttered mess, so I started over and built it right.
I've been vibe coding for a while now. Recently I stumbled across an article that put a name to the nagging feeling I've had for ages: Cognitive Debt.
Working with JavaScript's built-in Date object has always felt like defusing a bomb with oven mitts on. The Temporal API is here to fix this mess.
Installing Flutter on Arch Linux is one of those tasks that sounds straightforward until you actually try it. Here are three paths ranked from grandma-friendly to why am I doing this to myself.
