just received notice that an Eng leader here at Cloudflare who moved to Portugal from the US has had his residency permit denied in the months he has been waiting for one, he has hired five full-time engineers and six interns here in Lisbon. alongside the hundreds of others we employ here @govpt @mpresidencia_pt the immigration insanity here is making it increasingly hard to just operate a tech office in Lisbon much less grow one

I know Mahomes and Allen exist, but Caleb Williams may be the QB I’d choose right now to build my NFL franchise around. He’s incredible.

I'm Incredibly excited to be joining @Cloudflare today as SVP of Emerging Technology. I’ll be leading ETI, Cloudflare’s skunkworks, working with the ridiculously talented and ambitious team there to build Cloudflare’s next generation of products and businesses. The mandate for ETI is to look beyond the core business today, make ambitious bets on what will matter tomorrow, and turn those bets into businesses that shape the company’s future. I’ve long believed that open and free access is one of the most powerful forces we have for creativity, competition, connection, and opportunity. Open source software, open models, and access to knowledge give more people the ability to build—and an open Internet lets them reach the world. But keeping the web open means constantly pushing back against walled gardens and gatekeepers. As AI changes how people find information, use software, and interact with each other, preserving that access becomes even more consequential. Cloudflare is uniquely positioned to protect the open web and has a long history of doing so. We saw it again two weeks ago: when the php2shell vulnerabilities hit PHP, which runs almost 70% of the web, Cloudflare had protections live before the flaws were even public, automatically, for every site behind it, including the ones on the free plan. That independent global network puts powerful capabilities in the hands of builders everywhere. On Cloudflare’s developer platform, you don’t pick a region: every service runs in every data center, in nearly 350 cities around the world. And it’s backed by a culture of experimentation and shipping that I’ve admired for years. The team consistently turns ambitious technical ideas into things people can actually use. I’ve been a Cloudflare user for over a decade, and today it’s where I build and run my own projects, from a website for a friend’s barbecue restaurant to the infrastructure behind my home network. I’ve experienced firsthand how much it makes possible. From Stack Overflow to Stacks to investing in and advising founders, I’ve always loved building things that help people build things. The common thread is giving more people access to the tools, knowledge, and infrastructure to build on their own terms. I love working with people who see what’s possible, giving them the room to pursue it, and building the teams and businesses that make it real. At Cloudflare, I get to bring those things together at an extraordinary scale, in service of a mission I deeply believe in: helping build a better Internet. There’s a lot to build. I’d love to hear what you think we should take on. And if you want to come work on it, DMs are open.

i was telling a friend about the french 60s film kick my husband and i went through a little while ago and he asked for my list of recs im bad a letterboxd so here’s my french 60s film starter kit as a film not-quite-nerd-but-enjoyer, by director: truffaut: - the 400 blows (it’s like ferris beuller’s days off but dark; in some ways portrays the experience of how hard it can feel to be a child so well. it’s technically the first of a series that follows the main character) - jules & jim (male friendship movie, and manic pixie dream girl movie) demy: - umbrellas of cherbourg - young girls of rochefort - a slightly pregnant man these are a bit more campy / musical. but still so so good, especially umbrellas which if you don’t cry at the end idk what to tell you. the colors are also just spectacular agnes varda (married to demy btw): - cleo from 5 to 7 goddard: - breathless - contempt i’ll be honest, goddard is not my favorite though i have come to appreciate him. if you watch breathless, you must watch linklater’s nouvelle vague melville: - army of shadows — this might be one of my favorite movie of all time. it’s quite heavy though. but amazing. and i haven’t seen mandalorian but have been told it feels inspired by - le samourai — no one will ever look cooler in a movie than delon in this - le cercle rouge i think melville is possibly my favorite buñuel: - belle de jour — dark, twisted fantasy of a bored housewife - the discreet charm of the bourgeoisie — this one is fun but very trippy lesser known directors, but great movies: - a man and a woman (claude leluche) — might be the best romantic movie of all time. this became the inspiration for a project @elithrar is working on - the sicilian clan — very fun heist movie. delon & lino ventura (who will become one of your faves too), and soundtrack by ennio morricone is amazing

We are going to drive cost per task to zero. We will not allow a duopoly to tax humanity on intelligence. We trained on humanity’s data, the least we could do is give back and let everyone prosper.

What are your big asks from @Cloudflare ? Where are we falling short today? This might be analytics, logs, traces, going from a problem to the answer, etc. We've shipped a lot of great tools but I'm sure that's just shown new gaps - so tell me about them! 👀

The Cloudflare's writeup on our php2shell response is up. Rules went live at 03:02 UTC, about 9 hours before disclosure. Unfortunately the vulnerability leaked early, so we were already watching attackers mutate payloads against the rules and updating as variants appeared. New rules keep landing in the WAF changelog. Expect updates through out the day. We will have a more thorough post of what we had to build to better protect people coming shortly. PHP runs almost 70% of websites. The flaw is in the runtime, so updating plugins won't fix it. Patch PHP. blog.cloudflare.com/php-vuln…

Enjoying hearing @drfeifei and @mpaper2000 speak on stage at #CloudflareConnect about AI, humanity, efficiency, and what we don’t talk enough about at this moment (spoiler alert: human agency over AI).

Today we introduced a novel system one model, Clairic, based on regression instead of classification (i.e. decision models like Clef). This enables estimation of continuous values without having to exhaustively list choices upfront. It also enables very efficient extraction of structured data from unstructured inputs. Open weights coming soon!

First Clef, now Clairic. Clef picks from options you give it. Clairic extracts values from a receipt photo, a support email, or a CSV of daily counts. You get typed answers with confidence scores in one forward pass, without generating output tokens. Use them ahead of an LLM and you can keep the raw input away from the model writing the reply. It gets the extracted values, not the original email. Great work by @michellechen and the Workers AI team. In preview now, with open weights coming soon.
