The Nerd-to-English Dictionary

plain english for the meeting you're about to fake your way through.

you've nodded in a meeting at a word you didn't know. everybody has. that nod is the whole problem: half of tech vocabulary is plain ideas wearing a lab coat, kept fuzzy on purpose.

$0+ · pay what you want. zero is the price, and it's a fair one.

Cover of The Nerd-to-English Dictionary: Talk Nerdy to Me, by Mathieu Kessler. Plain english for the meeting you're about to fake your way through.

why this exists

a confused room keeps paying the person who sounds certain.

jargon is gatekeeping. most glossaries explain a buzzword with three more buzzwords. this one peels the marketing off and hands you the plain version, accurate underneath the joke, every time.

how every entry works

three lines. one term. zero fog.

the truth

the real definition. accurate. the version you could repeat to an engineer without getting a look.

zara's translation

the version that actually sticks. the one you'll remember at 4pm in the meeting that matters.

spotting the bluff

what it means when someone leans on the word too hard. the tell. and a bluff rating, so you know how much is real and how much is air.

serverlessbluff: medium
the truth
a model where the cloud runs your code on demand and manages the machines for you, you pay per run, not per server.
zara's translation
a room full of servers with a sign on the door that says no servers.
spotting the bluff
when someone implies there are literally no servers. there are. you just stopped getting the invoice for them by name.

a taste · 12 of 181

heard a word? look it up.

type a term, or filter by bluff rating. this is the lookup that takes ten seconds, the full book does it 181 times.

cloudbluff: low
the truth
computing (servers, storage, services) you rent over the internet instead of owning, billed by what you use.
zara's translation
someone else's computer in a warehouse, rented by the hour.
spotting the bluff
when "move it to the cloud" is said like a strategy and not a hosting bill.
serverlessbluff: medium
the truth
the cloud runs your code on demand and manages the machines; you pay per execution, not per server.
zara's translation
a room full of servers with a sign on the door that says no servers.
spotting the bluff
anyone insisting the servers are gone. they moved, that's all.
agentbluff: high
the truth
software that takes actions toward a goal: calling tools, making decisions, not just answering questions.
zara's translation
a chatbot tells you how to book the flight. an agent books it, checks your calendar, and adds it to the trip.
spotting the bluff
when "agentic" gets bolted onto a glorified if-statement.
synergybluff: vapor
the truth
the idea that combined efforts beat the sum of their parts. real in theory, almost never measured.
zara's translation
the word you reach for when you can't say the thing. if you could finish the sentence, you'd have finished the sentence.
spotting the bluff
it's vapor. retire it.
on-prembluff: low
the truth
software and hardware you run in your own building or data center, not rented from a cloud provider.
zara's translation
the closet the cloud replaced. your servers, your power bill, your problem at 2am.
spotting the bluff
rarely a bluff, just said with a sigh by whoever still maintains it.
egressbluff: low
the truth
the fee a cloud provider charges to move your data out of their network.
zara's translation
free to check in, you pay to leave. the cloud is a roach motel for data.
spotting the bluff
not a bluff, a surprise, usually found on the invoice you didn't read.
hallucinationbluff: low
the truth
when a language model produces confident, fluent output that is simply false.
zara's translation
the model would rather invent an answer than admit it doesn't know. like a certain coworker.
spotting the bluff
real and well-named, the bluff is the demo that pretends it never happens.
zero trustbluff: medium
the truth
a security model where no user or device is trusted by default; everything is verified, every time.
zara's translation
the bouncer cards you even though you've come here for years. especially then.
spotting the bluff
real model, sold as a product. "zero trust" on a brochure usually means "one more dashboard."
CI/CDbluff: low
the truth
continuous integration / delivery, automating how code gets tested and shipped.
zara's translation
the robot that catches your mistakes before customers do, then ships the fix while you sleep.
spotting the bluff
low, though "we have a pipeline" can quietly mean "one script and a prayer."
data lakebluff: medium
the truth
a store that holds raw data of any shape, unstructured, until someone needs it.
zara's translation
a warehouse where everything gets thrown in "just in case" and nothing is ever found again.
spotting the bluff
real idea. when no one governs it, the lake becomes a swamp, and they stop saying the word.
cloud-nativebluff: high
the truth
software built for the cloud from the start: containers, microservices, auto-scaling, rather than lifted there later.
zara's translation
built for the cloud on purpose, not dragged there kicking and screaming.
spotting the bluff
mostly used as an insult. "that's not very cloud-native" often just means "newer than yours."
tokenbluff: low
the truth
the chunk of text an AI model reads and writes in, roughly a word-piece. you're billed by the token.
zara's translation
the syllables the AI charges you by. "unbelievable" might run you three.
spotting the bluff
low, real unit, just invisible until the bill explains your demo.

no match in this taster, but it's almost certainly one of the other 169. grab the full A–Z →

the bluff rating

how much of the word is real, and how much is air.

low

low

real, just overused. the word means something, people just say it too much.

medium

medium

real core, marketing wrap. there's a true idea under the gloss.

high

high

mostly air. a sliver of meaning, a lot of theatre.

vapor

vapor

means nothing. retire it. it exists to fill a silence.

what's inside

seven sections, sorted by the meeting you just survived.

§1

the cloud & the closet it replaced

cloud, on-prem, virtualization, the primitives.

§2

the plumbing

networking, top to bottom.

§3

where the data sleeps

databases, SQL vs NoSQL, warehouses, lakes.

§4

the robot that finishes your sentences

tokens, context, hallucination, agents, the hype words.

§5

why the bill is insane

egress, reserved vs spot, the horror-novel invoice.

§6

how it ships & how it doesn't get robbed

CI/CD, zero trust, the acronym soup.

§7

the buzzword graveyard

the words that mean nothing, with a bluff rating.

three ways to use it

look it up. read it for fun. screenshot it.

look it up

you heard a word. the A–Z index gets you the real version in ten seconds, mid-meeting, no one the wiser.

read it for fun

pick the section that matches the meeting you just survived. it reads like a friend two drinks in who actually knows her stuff.

screenshot it

every entry is a card, built to send to the next person who says "synergy" with a straight face.

the obvious questions

yes, it's actually free.

is it really free?
yes. free, or free with your email so i can tell you when there's more. no trial, no card, no catch.
do i need to be technical?
no. that's the entire point. if you sit near tech and want to stop nodding at words you don't know, this is for you.
what do i get?
an EPUB and a PDF. 181 entries across seven sections: each one term, true definition, plain-english translation, and the tell. plus an A–Z index.
is it correct, or just funny?
both, on purpose. the definition under every joke is accurate. a translation that bends the truth got cut.
what's the catch?
there isn't one. it's the widest, friendliest door into everything else i make. if you like it, the rest is one click away. if you don't, you got a free dictionary.
is there a paid version?
this is the cheat sheet. the field guide, Decoded by Zara ($9), is the long version, where the hard terms (embeddings, ACID, the whole CAP-theorem mess) get a full chapter. start free. go deeper if you want to.

stop nodding

name your price. zero is the default.

the dictionary is free and stays free. but if it saved you from one more confident nod, you can leave a tip, same 181 entries either way.

leave it at $0 for an instant free download, or set any amount to chip in. you'll get the EPUB + PDF either way.

liked the cheat sheet? read the field guide.

the dictionary is the fast version. Decoded by Zara ($9) is the long one: embeddings, ACID, the whole CAP-theorem mess, each with the full chapter a dictionary can't give. start free here, go deeper if you want.
