Well, well, well. The public JSON formatter sites your developers paste production data into have been quietly publishing every paste for about seven years. Naturally, we read all seven years of it.

200,000+ documents. Cloud keys, SSH keys, payment API keys, whole tax returns with SSNs, people's full identities, bank balances. Nobody hacked anything. People pasted it in to make it look tidy, as you do.

Full writeup below. Yes, it's as bad as it sounds.

Interesting times ahead. I was made redundant on Friday so in a month I’ll be working on @SixLabors full time. Here’s hoping the new license key requirements drive up enough custom!

I’m nervous but excited to see what I can do.

Mexico paid $20 million for eight minutes in this movie. Then those eight minutes forced them to invent an entire cultural tradition.

Before Spectre, Mexico City had no Day of the Dead parade. The holiday was celebrated at home, at cemeteries, with family altars. Quiet, intimate, centuries old. Sam Mendes fabricated a massive street parade for the opening sequence, shot it with 1,500 extras in skeleton costumes across the Zócalo, and audiences worldwide assumed they were watching a real annual event.

Mexico's government had negotiated hard for the placement. Leaked Sony hack emails showed officials offered up to $20 million in tax incentives for four minutes of positive portrayal. Sony was drowning in a $300 million budget. The deal included script changes: the Bond girl had to be a Mexican actress, the villain could not be Mexican, and the city's modern skyline had to appear on screen.

Then the movie opened in 182 countries and tourists started booking flights to Mexico City for the parade.

The parade that did not exist.

Tourism authorities panicked. Visitors were arriving expecting the spectacle they saw in the film and finding nothing. So in October 2016, the government spent $500,000, hired 650 volunteers, built dozens of floats and giant skeleton marionettes, and staged the first real Día de los Muertos parade in Mexico City's history. 250,000 people showed up. They openly called it a "Spectre-style parade" in press materials.

Ten years later, the parade draws millions. Anthropologists call it the "pizza effect," where a cultural element gets exported, transformed abroad, and reimported as authentic. Mexico's most famous public celebration of its most sacred holiday was invented by a British director shooting a $300 million spy movie.

That tracking shot is doing more for Mexico City's economy every November than the $20 million they paid for it.

One of my favourite nuggets of Windows lore is that the registry containers are named hives because one of the og developers working on cutler's team was deathly afraid of bees.

[Microsoft Dev Docs @docsmsft]

If Windows were designed today, would the Registry still exist? Mark Russinovich breaks down how the Registry works—and why a more flexible, file-based configuration model might win out in a modern design.

@kellabyte @davidfowl @aspiredotdev There are some improvements to be had with emitting shorter span links instead of long running open spans in that regard. I'm not sure the community has figured out enough asynchronous trace conventions in that regard yet though.

This is the greatest video I’ve ever seen. No notes. The lifeless clanker carcass just laying there. No crowd reaction, anything. Just Billie Jean. Until its lifeless shell is shamefully dragged off. Purely amazing.

Personal update: I've joined Anthropic. I think the next few years at the frontier of LLMs will be especially formative. I am very excited to join the team here and get back to R&D. I remain deeply passionate about education and plan to resume my work on it in time.

Atlassian's revenue: $1.79 billion last quarter
Atlassian's move: fire the engineer who built their infrastructure

his move: post a 38-minute breakdown of every system he built, free for anyone to copy

what he revealed:

> Envoy proxy instead of enterprise load balancers
> sidecar architecture for auth, logging, rate limits
> DynamoDB + SQS for async provisioning
> Packer + SaltStack for automated VM deployments at scale

Atlassian charges per employee across 350,000 customers

this guy just handed you the enterprise playbook for free

Someone on Reddit asked to see some benchmarks so I was happy to share. ImageSharp v4 is scorchingly fast and will only get faster as the runtime improves.

This article also contains a benchmark for ImageSharp Drawing v3 which might be a bit of an eye-opener for some people.

I strongly believe there are entire companies right now under heavy AI psychosis and its impossible to have rational conversations about it with them. I can't name any specific people because they include personal friends I deeply respect, but I worry about how this plays out.

I lived through the great MTBF vs MTTR (mean-time-between-failure vs. mean-time-to-recovery) reckoning of infrastructure during the transition to cloud and cloud automation. All those arguments are rearing their ugly heads again but now its... the whole software development industry (maybe the whole world, really).

It's frightening, because the psychosis folks operate under an almost absolute "MTTR is all you need" mentality: "its fine to ship bugs because the agents will fix them so quickly and at a scale humans can't do!" We learned in infrastructure that MTTR is great but you can't yeet resilient systems entirely.

The main issue is I don't even know how to bring this up to people I know personally, because bringing this topic up leads to immediately dismissals like "no no, it has full test coverage" or "bug reports are going down" or something, which just don't paint the whole picture.

We already learned this lesson once in infrastructure: you can automate yourself into a very resilient catastrophe machine. Systems can appear healthy by local metrics while globally becoming incomprehensible. Bug reports can go down while latent risk explodes. Test coverage can rise while semantic understanding falls. Changes happens so fast that nobody notices the underlying architecture decaying.

I worry.
