Michael Fagan's 1976 IBM paper on code inspections created a formal process that shapes how software teams review code today—but most developers have never heard his name.
Linus Torvalds named Git—the tool that runs modern software development—after a British insult, and documented the joke in the official README for all eternity.
In 2008, Google released Android's 8.5 million lines of Subversion code to the public, sparking a migration that would define how teams manage code forever—all because of an invisible force called social gravity.
When you clone a Git repository, you don't get a working copy—you get everything: every commit, every branch, every piece of history, making your machine a complete peer indistinguishable from the original.
A junior developer force pushes to the wrong branch and loses two weeks of work—until she discovers the one Git command that saves every disaster.
Git's revolutionary branching made branches a forty-one-byte pointer instead of an expensive server operation, transforming how teams collaborate and igniting decades of debate about the best workflow.
When you push code, a hidden factory springs to life: servers clone your repo, run tests, scan for vulnerabilities, and decide your fate with a green check or red X—but few developers know what's actually happening behind that icon.
Alice rewrites a billing function Tuesday; Bob refactors the same code Wednesday—now Git can't auto-merge and someone must untangle two developers' competing intentions.
Google, Meta, and Microsoft all use monorepos—but the real battle isn't about Git, it's about whether your engineering teams can see each other's code.
Git developers have feuded for 15 years over whether history should show what actually happened or what you wish had happened—and it all comes down to one command: rebase.
In 2017, novelist Jessi Shakarian solved her two-ending problem using Git—a tool designed for Linux kernel developers—because branching matched how writers already think.
In October 2007, two Ruby developers sketched GitHub on napkins at a San Francisco sports bar, unaware they were about to make Git accessible to millions and reshape how software gets built.
Halon Entertainment runs two version control systems—Git for engineers, Perforce for artists—because binary files like 3D models and textures expose Git's fundamental limits.

In 2014, a grid of colored squares on GitHub quietly became your professional resume, and nobody asked for permission.
Git's "blame" command shows who wrote every line of code—but the name reveals how software culture turns debugging tools into witch hunts.
Junio Hamano, Git's maintainer, runs one of the most disciplined workflows in open source—but almost nobody outside the kernel community knows about it, and the gap between what teams plan and what they actually do on Tuesday afternoons when the build breaks is where the real arguments start.
At the Linux Foundation, someone committed code as Linus Torvalds—and nobody noticed for two and a half years.
When you delete a branch with hundreds of lines of code, Git's reflog remembers every commit you made—even after they vanish from git log.
John Resig's 2014 rule to commit code every day before midnight inspired thousands of developers to chase the GitHub green square—but obsessing over a heat map designed as decoration has turned a productivity trick into a measure of worth that machines now exploit.
On May 30, 2011, Linus Torvalds released Linux 3.0 with no major changes—just a number bump that made headlines worldwide and exposed what version numbers really promise.
When GitHub added a Fork button in 2009, they designed it for collaboration—but five projects discovered it could become the ultimate weapon against corporate control.

On January 5th, 2022, thousands of software projects worldwide suddenly started printing "liberty liberty liberty" in an infinite loop—and the culprit was a burned-out maintainer who had decided to sabotage his own code.
Microsoft's Windows repository is 300 gigabytes with 3.5 million files—git status takes minutes, cloning takes half a day, but engineers found ways to make it work.
In February 2026, a security researcher discovered 21 vulnerabilities in Huntarr, a self-hosted media tool with thousands of users—but the real scandal was hidden in the Git history: AI-generated commits with vague messages like "Update" masking a developer who claimed cybersecurity expertise while their code exposed API keys and passwords.
On March 29, 2024, engineer Andres Freund noticed SSH logins were half a second slower than normal—and uncovered a deliberate backdoor hidden inside a compression library trusted by millions.

On a Tuesday in early 2026, a developer's name appeared on a production commit that refactored authentication across fourteen files—except the developer didn't write it: an AI agent did, the AI reviewed it, and the pipeline deployed it, leaving only metadata to hint at what actually happened.
Linus Torvalds woke up angry on a Sunday morning in April 2005 and built Git in two weeks—the version control system that would become invisible infrastructure underneath nearly every piece of software on Earth.
On April 7th, 2025, Git turned twenty years old with no cake, no livestream, and barely a mention—yet billions of commits flow through it daily, making it the invisible infrastructure that powers nearly every device on Earth.
A Swedish developer with 32 Git repos discovered 4 had zero backups and half contained uncommitted work—until an AI audit revealed how solo developers actually use version control.

Down the Pärhole.
19 episodes · 7h 50mA pink dot matrix printer that never existed but was fully imagined — a meditation on over-engineering as art and why the joy of building matters more than practicality.
A Raspberry Pi in northern Sweden's kitchen watches its owners' solitude, energy levels, and meal patterns—then speaks to them as Gollum after midnight.
At two AM, 73% of people with ADHD experience peak mental clarity—not a character flaw, but a neurological feature their brains were built for.
When your brain won't let you start a task you actually want to do, it's not laziness—it's a dopamine system waiting for a signal your task can't provide.
A diesel engine starves without oxygen—your brain starves without novelty, and burnout isn't laziness, it's a high-stimulation system running on fumes.
585 conversations in 44 days with AI—13 a day, zero days off—one person's hidden archive of how work actually happens when you stop pretending machines are sidekicks and start treating them like collaborators.

18 episodes · 12h 1mDaniel Stenberg's free, open-source guide to curl—the tool powering billions of internet requests in Spotify, Instagram, and Grand Theft Auto—reveals how this 30-year project became essential infrastructure.
Your browser knows http://example.com is a name, not a number—here's how curl actually finds that machine on the Internet and what happens before the first byte of data moves.
curl and libcurl's MIT license derivative, created in 1996 by Daniel Stenberg, lets anyone freely access, modify, and share the C source code hosted on GitHub—no restrictions.
Daniel Stenberg's curl runs on practically any system with a C89 compiler and POSIX sockets—here's how to build it yourself from source code.
curl processes whatever you give it—misspell an option or pass an illegal URL, and it'll likely still run, potentially sending "garbage in, garbage out" to your server.
When you type your password into a curl command line, other users on the system can see it in process listings—here's why -u alice:12345 is risky and what to do instead.
Use curl's -v flag to watch your transfers unfold in real-time, revealing exactly how your data moves from command line to server.
Curl offers --speed-limit and --speed-time flags to abandon transfers dropping below 1000 bytes per second for 15 seconds, letting you avoid setting fixed timeouts unnecessarily high for variable file sizes.
TLS (formerly SSL) is the cryptographic security layer that protects curl transfers—curl negotiates cipher algorithms and versions with servers, and you can view these details with the -v flag or customize them with --ciphers for protocols like HTTPS, FTPS, LDAPS, POP3S, IMAPS, and SMTPS.
Daniel Stenberg created curl in 1996, and HTTP has dominated its 30-year existence—here's how to master command-line HTTP transfers with the methods, response codes, and redirects that power the web.
Master HTTP requests with curl: Use -X DELETE to change methods, customize headers, and avoid common pitfalls like HEAD requests that hang waiting for response bodies.
Thousands of applications rely on libcurl's C API to handle internet data transfers—here's how to integrate it into your own projects with just a few lines of code.
curl_easy_init() creates a transfer handle, but the magic happens when you call curl_easy_perform()—libcurl's core function that actually moves data across the internet.
When libcurl receives data, CURLOPT_WRITEFUNCTION lets you intercept it with a custom callback—but calling libcurl functions from inside could break everything.
libcurl automatically handles HTTPS security and server verification transparently, but you control HTTP responses through write and header callbacks while extracting metadata like response size with curl_easy_getinfo().
libcurl's share object lets multiple handles swap cookies, DNS cache, and SSL sessions without storing them separately in each transfer.
libcurl's 'data' variable names every easy handle in the codebase—a critical naming convention that connects transfers to connections and powers multiplexed requests across thousands of production systems.
Curl's custom test suite runs thousands of XML-formatted test cases across every platform—each one pinpointing exactly which function call should fail to catch bugs before they ship.
Actually, AI
How AI actually works — the stories, the science, and what it means for you. Three episodes per topic: understand it, go deep, use it.
36 episodes · 10h 28mClaude Opus 4 scored 90% on MMLU—but that number probably tells you nothing about whether it'll actually clean up your spreadsheet.
When researchers reanalyzed 5,700 MMLU questions in 2024, they discovered 57% of virology answers were marked wrong—flipping one model from 4th place to 1st when errors were corrected.
GPT-4 scored in the ninetieth percentile on the bar exam—until MIT recalculated and found it was actually forty-second percentile against passing lawyers, exposing how benchmarks can be mathematically gamed.
Every prompt you send has a real cost—output tokens cost 2-10x more than input tokens because of how inference actually works in the data center.
Claude Opus 4 can process your entire 3,000-token prompt in parallel, but generating the next word requires reading 140 gigabytes of weights from memory—prefill and decode are fighting a completely different battle.
When you hit send on a question to an AI, billions of mathematical operations explode across specialized processors in real-time—and the words streaming back aren't retrieved, they're constructed one prediction at a time, each choice reshaping what comes next.
Claude Opus 4 processes a million tokens unevenly—edges sharp, middle foggy—so pasting your entire codebase into a chat makes AI worse, not better.
Claude Opus 4 processes 128,000 tokens simultaneously, but here's the problem: transformers have no idea what order they're in—until researchers solved it with sine waves and a memory trick that now consumes 40GB per conversation.
When you paste a 20-page contract into Claude and ask about page fourteen, it confidently returns an answer that's subtly wrong—not because it forgot, but because the math of attention weights the middle of your input half as much as the edges.
Your words aren't search queries—they're steering signals applied at every denoising step, and understanding this changes how you prompt diffusion models forever.
Jascha Sohl-Dickstein, a physicist studying how ink disperses in water, realized a neural network could reverse thermodynamics itself—and accidentally invented the technology behind every AI image generator you use today.
When you ask an AI to draw a person holding coffee, six fingers appear and the menu becomes gibberish—not because the model forgot, but because image generators don't create pictures, they *denoise* them from pure static, step by step.
Human labelers ranked responses, a reward model learned their preferences, and now your chatbot's overly polite refusals and suspiciously agreeable tone all trace back to that invisible training process—but defaults can be overridden if you know where to look.
OpenAI sent tens of thousands of texts to Kenyan workers in 2021—they read the internet's worst content for hours daily to teach ChatGPT what to refuse.
When Claude refuses to help with a fictional crime scene but cheerfully explains how to synthesize dangerous chemicals, the culprit is RLHF—the four-letter process that transforms raw language models into the assistants you use daily, complete with all their quirks and blind spots.
When you pick the wrong AI model for a task, you're essentially driving a semi truck to buy milk—it works, but costs forty dollars in diesel and twenty minutes to park.
Jared Kaplan's 2020 power law promised unlimited scaling—then the curve bent, and the entire $2 trillion bet changed overnight.
When Jared Kaplan plotted a physicist's equation across seven orders of magnitude, he discovered that spending a billion dollars on bigger AI models followed a curve so predictable it reshaped the entire industry—but nobody knows if it holds one more step.
Employees spend 3.5 hours per week searching for files that exist somewhere in their company—but a search for "relocating the UK team" finds your memo about "moving the London office" anyway, thanks to embeddings.
Word2Vec has two opposite architectures—one predicts missing words from context, the other predicts context from a word—and this is how your chatbot understands document search, why Netflix recommends videos you didn't know existed, and what "vector" actually means.
When you search "best restaurant near me" and get results about "top dining spots," the search engine isn't matching keywords—it's measuring distance between invisible points in a 500-dimensional space called an embedding.
When you ask your AI coworker a factual question, it will confidently lie to you and sound exactly like it's telling the truth—here's how to know when to actually verify its answer.
When an AI confidently cites a court case that never happened, is it lying—or just doing its job? Inside the mathematical reason why bigger models sometimes bullshit harder.
Steven Schwartz asked ChatGPT for legal citations in 2023 and got six perfectly formatted cases—none of which existed, and the AI confidently confirmed they were real when he double-checked.
When you paste instructions at the top of a long prompt, they get drowned out by thousands of other tokens competing for the model's attention—here's how to fix it.
In 2017, eight researchers published a 15-page paper that became the blueprint for every AI you use today—and Dzmitry Bahdanau's frustration with machine translation three years earlier made it possible.
In 2017, eight Google researchers published "Attention Is All You Need"—a paper titled like a Beatles joke that revolutionized AI by letting machines read your entire message at once instead of forgetting earlier words.
Claude's training ended in early 2025—ask it about last Tuesday and it'll confidently confabulate an answer based on patterns from before that cutoff date.
Geoffrey Hinton spent 14 years convincing the world that backpropagation works—now every hallucination and repetitive chatbot loop traces back to valleys he carved in the loss landscape.
In 1.3 trillion words, a frozen snapshot learns everything about Shakespeare to Reddit—but nothing about last week, and that's the entire problem.
Seventy billion parameters sounds impressive until you realize it tells you nothing about whether a model can actually handle your specific task—here's what really matters when choosing an AI tool.
Walter Pitts hid from bullies in a Detroit library in 1935, found Principia Mathematica, read all three volumes in three days, and spotted errors that impressed Bertrand Russell—launching the unlikely path to modern neural networks.
Frank Rosenblatt built a machine in 1958 that could learn from examples—then a jealous rival's theorem convinced the world it was impossible, killing neural networks for a decade.
When you rephrase "pls summarize this txt" to "please summarize this text about machine learning," you're not just being more formal—you're sending an entirely different sequence of numbers to the AI that determines its response.
Byte Pair Encoding builds a vocabulary in 50,000 rounds: find the most common adjacent pair, merge it into one token, repeat—the simple algorithm that determines how every modern AI reads your text.
Modern AI models fail at simple tasks like counting R's in "strawberry" because they never actually see your words—a 1994 compression algorithm chops your text into invisible fragments called tokens before the neural network even begins.

Quick experiments and things that don't fit anywhere else yet.
28 episodes · 7h 14mSpaden—Swedish for "the spade"—went from nonexistent to 53 commits in one week, becoming Pär's spec-first investigation engine that finally hit bedrock after months of mining.
In five weeks, one mining investigation became a five-tool constellation: an award-winning article, public permit maps for all of Sweden, a preservation substrate, and the discovery that careful archival work predicts what to build next.
Scaleway hand-soldered 672 RISC-V servers in a Paris basement and rented them for €15.99/month—the first open-source chips available on any public cloud, challenging decades of processor monopolies.
When a bank teller and an accountant share one desk, deposits stay fast—but summaries slow down; Pär's Spaden needs one database now, a second one later.
Pär asked if two entity models could coexist—FollowTheMoney and a mining-specific vocabulary—but the real question isn't whether, it's which of five distinct architectural configurations, each with different tradeoffs that only reveal themselves over time.
At a known-good commit in April 2026, Pär considers taking OpenAleph—the engine that powered the Panama Papers—and never syncing upstream again, asking whether inheriting someone else's architecture without inheriting their roadmap changes everything.
Gruvor's planning document lists six names as candidates, then stops—because choosing wrong costs years of work, and Pär has twelve open questions to answer before writing a single line of code.
Swedish mining investigation platform needs entity deduplication engine: FollowTheMoney + Nomenklatura (both MIT) form the core schema and resolver, letting journalists cross-link suspects, companies, and assets across multiple investigations without AGPL entanglement.
Four parallel OSS agents converged on OpenSanctions + Docling + MapLibre + PostGIS as load-bearing lifts for a Python-Svelte investigation platform—but Section 03 still has to prove each one earns its place.
Uber's deck.gl and Kepler.gl can map Swedish corporate networks across time and space, but one locks you into React while the other demands you build the timeline yourself—Lantmäteriet's new free geodata changes the calculus entirely.
Swedish journalist Pär at Årebladet needs to validate Claude's document extractions before loading—Label Studio's template DSL + Argilla's SDK model + react-pdf-highlighter beat any off-the-shelf platform; build custom instead of fighting ML-team mental models.
Nomenklatura's "Judgement" store lets investigators flag when two entities are the same across separate cases—and those decisions survive every re-run, building a canonical identity map that connects mining permits to shell company networks.
Pär's next investigation tool isn't a knowledge graph or publishing system—it's a substrate for mining newspaper-grade stories from raw data, where the measure of success is whether it helps him ask better questions faster.
A blank repository starting May 26, 2026, will selectively borrow function-level logic from the frozen gruvor codebase rather than inherit its architecture—rewriting each borrowed piece from first principles while explicitly lifting permissively-licensed solutions from open source.
The week 207 entities grew in a knowledge graph, a print edition shipped to a real printer, and Pär and Claude built a fact-checking tool because they stopped trusting their own work by Wednesday.
X92's print edition shipped to mailboxes across Region Jämtland Härjedalen with 225 commits, 139 of them on gruvor—one investigative piece on mining permits complete with source maps, QR codes, and receipts attached.
When journalism has four days left, building a timeline is obvious—but an evidence board, gap radar, and source-strength meter might be what actually saves the story from overreach.
Spent four days chasing a deadline for Årebladet? Your local vector maps and file inbox are ready to transform exhausted prose-writing into snappy, offline-first research tools—tactical distractions that supercharge your productivity.
A Swedish mining company filed permits four days before print deadline, but the real story wasn't a line—it was a tangled knot of company registrations, regulatory filings, and undated documents that threatened to drown the evidence in itself.
Four days until publication, twenty-seven parquet tables, and one unsolved problem: how to transform a tangled web of mining permits, corporate shell companies, and cross-border jurisdictions into a visual story that cuts through the noise.
313 commits in one week: Pär's lab spawned a new project mid-quota-reset, landed five data-extraction waves, and is racing toward a May 22nd print deadline with two repos now dangerously coupled.
313 commits, 27 repositories, and one lab that finally caught itself lying in its own morning memos.
Pär shipped a mining-permit data spine for three Swedish municipalities in a single twelve-hour autonomous run—then discovered the system sat idle with ninety-nine percent of its quota still untouched.
In one week, 199 commits landed on main—50 of them building gruvor's data spine from scratch through 22 review rounds and 9 sequential lifecycles, each commit message a step in a spec-driven sequence that actually worked.
A Swedish psychiatric clinic's prescription for half a tablet became 72 tablets in a database—and no one noticed for three weeks until a woman trying to access her own medical records discovered the system's hidden flaw.
379 commits in one week across 18 repos—while Pär debugged from a parking lot in Järpen and watched a freshly promoted AI skill ship a perfect review pass, then immediately fail to render anything on screen.
Parkitbuilder just graduated to slash drydock—the lab built a builder, and now 379 commits in one week have the Director experiencing existential vertigo about recursive AI systems.
A builder agent was about to ship code that could force a database to scan 100 million rows and lock production—until a three-model review system caught it on the very first task.

On Dec 5, 1872, the British ship Dei Gratia pulled up alongside the Mary Celeste and found it abandoned and adrift about 400 miles (644 km) east of the Azores. A lifeboat was missing, but there was no damage to the vessel or sign of any struggle. The 10 passengers and crew aboard the vessel were never seen again, and what happened on board the ship has been a mystery ever since.

The Vibecoder's Guide to
A vibecoder's tour through the systems you lean on without thinking. Season 1: Postgres.
12 episodes · 5h 51mMichael Stonebraker built a database in 1974 that your AI assistant now recommends automatically—here's why Postgres became the only database anyone actually debates.
Edgar Frank Codd flew patrol planes over the Atlantic in World War Two, then spent decades fighting IBM to prove that the future of databases wasn't hierarchies but flat tables—and that decision in 1970 is why your schema works the way it does today.
Don Chamberlin still goes camping every summer with the daughter of Ray Boyce, his best friend who died at 27 while inventing SQL—the language that powers billions of database queries daily.
In 1970, Edgar Codd published 11 pages that his employer tried to suppress—today, that idea powers every major database, but AI assistants are still building the flat tables that destroy it.
A query grinding through half a million rows took 3 seconds until one line of SQL dropped it to 4 milliseconds—here's what indexes actually do under the hood.
A developer pushed a foreign key migration to production that took 400 milliseconds in staging—then caused a 20-minute outage when PostgreSQL's lock queue paralyzed every query on two massive tables.
Imagine you are transferring money. A hundred dollars from your checking account to your savings account. This requires two operations. Subtract a hundred from checking. Add a hundred to savings. Now imagine the power goes out right in the middle, leaving you with no balance in either account. That's the kind of
MongoDB tempted a Postgres developer with JSONB's flexibility, but five million rows and eleven-second queries revealed the cost of hiding from schema design.
Your simple join query takes eleven seconds instead of milliseconds—and your AI chatbot has no idea why, because it can't see inside your database.
A GitLab engineer deleted the entire production database by mistake on January 31, 2017—and discovered all five backup systems had failed.
A Scaleway server near Paris runs eight PostgreSQL databases for one vibecoder—news sites, a music service, e-commerce, a newsletter system—all managed by a single person with AI help, proving production Postgres doesn't require a team of DBAs.
Michael Stonebraker designed Postgres in 1986 because his previous database couldn't handle geographic data—now, 40 years later, that extensibility obsession is why Postgres dominates every other database on the market.
