The condition nobody quotes

Ambedkar called civil disobedience the Grammar of Anarchy. He also said exactly when that judgement applies, and almost nobody quotes that part.

The Trading Machine, One Slide At A Time

An animated onboarding deck for new joiners in quant trading: front office to back office, multicast to matching engine, FIX to FPGA. Fourteen slides plus a four-slide appendix, every acronym you'll hear in week one, and what changes when your desk is in India.

We Are Not Slaves to Time. We Are Slaves to Each Other.

Most of what we chase rests on people we can no longer be bothered to need. A walk from the history of the clock, through the anthropology of money, to an uncomfortable place: the deepest cage isn't time, it's the comfortable lie that we had no choice.

"Unused RAM Is Wasted RAM" Is Not An Excuse For Chrome

Chrome eats your RAM and someone always replies: unused RAM is wasted RAM, relax. The slogan is true for the OS page cache and a bad defense of an app's footprint. A tour through page cache vs heap, demand paging, Linux overcommit vs Windows commit charge, macOS memory pressure, and Chrome's own allocator.

Almost Everything Correlates With Intelligence

Brain size, reaction time, height, trust, crime, myopia, income, faith. The list of things that track IQ is enormous and mostly real. But the correlations are small, they shrink the moment you look closely, and predicts almost never means causes. A tour of what actually tracks intelligence, and why.

Arguing with the Gita on Duty, from First Principles

A sequel to the undecidability-and-duty essay. Starting from nihilism, through Gödel, Turing and a few other limits, to an uncomfortable place: if nothing can prove itself from the inside, who is left to decide whether what I do is right? With a layman's quarrel with the Gita along the way.

The truth about Modi and "funded by CIA"

In 1993 (or 1994), years before he held any office, Narendra Modi toured the US on a State-Department-funded 'young political leaders' exchange. There's no CIA smoking gun here — and that's exactly the part that unsettles me. This is about the ordinary, legal machinery of cultivating who governs you, and the people it acts on without asking.

A Fair Market Is One the Regulator Can Replay

India does not need less exchange expertise. It needs less exchange-controlled evidence.

Money Buys the Microphone. It Does Not Write the Song.

A research journey through smoking norms, yoga, mindfulness, K-pop, Gulf museums, Marx, Bourdieu, Hinduism, Buddhism, and Ambedkar to ask whether culture and cultural influence are functions of wealth alone.

The Future Is Undecidable. Duty Is Not.

A follow-up to the India 2047 song essay, moving from Godel, Turing, and the halting problem toward anxiety, controllability, the Gita, Stoicism, and the old problem of duty.

A Satellite In Orbit Is Not Resilience

India's satellite security problem is not only in space. It is in the clocks, towers, runways, ground stations, and fallback layers that must keep working when signals are jammed or spoofed.

The Millisecond Nobody Was Supposed To Own

An HFT practitioner's map of India's electronic market abuse cases: same public data, unequal arrival time, private pipes, backup servers, gateway weakness, and fake order-book signals.

Writing a Song That Makes You Feel Worse Until You Get Better

A process note on India 2047, student protests, Let Down, syllable counts, YouTube comments, Godel, and the strange healing logic of sad music.

India in 2047

This was supposed to be one blog. It became three first. And here is the one they were always orbiting... the centenary year, the Viksit Bharat brochure, and the most honest answer I can give about what 15 August 2047 actually looks like.

Nehru: The 30 Percent Republic

The BJP has never crossed 40 percent of the national vote. About 24 percent of eligible Indians have authorised everything that has been built. A look at how a plurality runs a country, what the K-shape economy is buying, and the most honest answer I can give to the 2047 question.

Ambedkar: The Republic We Are Quietly Burning

The 1950 Constitution is Ambedkar's monument and the document being unmade in plain sight. A look at what is being dismantled, who is dismantling it, and the awkward fact that the Indian middle class — me included — is the bookkeeper of the erosion.

The BJP's Patel is a Fraud

They built him a 182-metre statue and forgot, very precisely, what the actual man did. A look at the founder the Hindu right cannot afford to read honestly — and the foreign-policy realism we keep needing in 2026.

The first minute

Ever notice how the same argument at 6am ends in tears, and at 1pm just doesn't? It's not you. It's chemistry. And the cost compounds in ways that don't get better with time.

One Piece: The Most Important Political Story of Our Time

A long-overdue take on Oda's 27-year epic — why it stopped being a pirate cartoon a long time ago, what Luffy actually represents, and why the kids who grew up on this story are going to look at the world very differently from the rest of us.

One OTP To Rule Them All: How Uber Bangalore Redesigned Ride Verification

Uber in Bangalore just moved to a single, non-regenerating OTP per ride — the same model Rapido has used for years. A deep dive into how this is implemented, the system design behind it, and why a static OTP is actually more secure than a regenerating one.

GitHub Becomes Plumbing

Why GitHub doesn't survive the shift to agent-first development.

When an ADR has eight problems

ADR-035 went into the repo as 'Microkernel + Plugin Architecture.' Two days later a long review session found eight things wrong with it. Some of them I had hedged on for ergonomic reasons. The rewrite is shorter, the system is smaller, and the lesson is uncomfortable.

From Nodes to Neurons

The rename that wasn't just a rename. Calling them 'neurons' and 'synapses' exposed three design decisions hiding in plain sight — plasticity, activation, signaling — and reshaped the domain around them.

Deterministic first

The principle that runs through every pipeline in moitumi: if a script, an algorithm, or a scoring function can answer the question, the LLM never sees it. The art is knowing where the ambiguous residual actually lives.

Extracting the daemon

Surfaces want to come and go. State wants to stay. The moitumi core became a long-running daemon, and the UIs became thin clients over a Unix socket — without throwing the embedded mode away.

The graph is not a neural network

Someone asked whether moitumi was effectively a GNN — and whether implicit learning (Siri, Google Assistant) would be a better path. The answer turned into an ADR.

Hexagonal architecture from line one

Most projects retrofit ports and adapters after the first painful refactor. moitumi started with the seam in place — here's what that bought, and where the dogma fights back.

The controller/view epiphany

The TUI's 'navigator' was secretly running the entire program. Pulling state out of the view and into a persistent non-visual controller turned the surface into something tmux could happily manage.

Why I'm building moitumi

What's wrong with the personal assistants we already have, and what 'cognitive assistant' actually means when you take the words seriously.

Devlog: Building an IFTTT Engine for RimWorld

How a simple if-this-then-that mod grew into a stateful automation framework — architecture pivots, requirement explosions, and lessons from trying to automate a game that fights you.

Accel World: The Anime That Could Have Been Classic (But Wasn't)

Virtual reality, acceleration, and a protagonist design that screams 'why?'

Bakemonogatari: A Masterpiece of Dialogue or Just Pretentious?

Wordplays, head tilts, and Hitagi Senjougahara.

Black Lagoon: When Morality Goes Out the Window

It's not just mindless action. It's about the twilight.

BLOOD-C: A Trainwreck You Can't Look Away From

Blood, gore, and characters with disproportionately long limbs. A rant.

Clannad After Story: Prepare to Cry Your Eyes Out

Forced sentimentality, moe overload, and a rant about why I just couldn't like it.

Code Geass: Strategic Genius or Narrative Chaos?

Entertaining, but let's be real about the 'strategy'.

Cowboy Bebop: Why It's Still the King of Cool

Jazz, space, and the weight of the past. BANG.

End of Evangelion: A Beautiful Nightmare

Dark, shocking, and incomplete without it. Also, Pachelbel's Canon.

Ergo Proxy: Deep Philosophy or Just Confusing?

Sci-fi, mystery, and Re-l Mayer's blue eyeliner. What more do you need?

Evangelion Rebuilds: Did We Need These Movies?

Visually stunning, but lacks the psychological depth of the original.

Fate/stay night: Ideally Flawed or Flawedly Ideal?

Action, romance, and the birth of an iconic Saber.

Fate/Zero: The Darkest Battle Royale in Anime

Epic battles, tragic characters, and Ufotable's god-tier animation.

FLCL: Fooly Cooly and the Madness of Puberty

Wacky, crazy, random, and absolutely awesome.

Fullmetal Alchemist 2003: Darker, Grittier, and Unforgettable

A different route from the manga, but a worthy tragedy.

Fullmetal Alchemist Brotherhood: Is Perfection Boring?

Satisfaction. That's the word. A pure adaptation done right.

Fuujin Monogatari: A Hidden Gem of Slice of Life

Relaxing, slow-paced, but maybe a bit too drafty on the animation side.

Gankutsuou: The Count of Monte Cristo in Space

A visual treat with textures that will melt your brain (in a good way).

Ghost in the Shell: The Cyberpunk Bible

Cybernetics, philosophy, and the definition of life itself.

Ginban Kaleidoscope: A Romance on Thin Ice

Figure skating, romance, and a sad ending that stuck with me.

Gundam 00: War, Peace, and Giant Robots

Lasers, explosions, and characters screaming full names.
