I don't tweet often, but this felt worth it. The dependability and safety of the systems I help build matter. So does the integrity of the company building them. Proud of @AnthropicAI for standing firm.

Being able to use Fast Opus early at Anthropic has been one of the best perks of the job. Come build with us and help drive a race to the top for safe, powerful AI.
Our teams have been building with a 2.5x-faster version of Claude Opus 4.6. We’re now making it available as an early experiment via Claude Code and our API.

I was an undergrad in 2006. Friends who've been in academia since then, and remain on campus today, tell very similar stories.
Two Harvard Crimson articles, one from 2006 and the other from 2023, describing the legendary Math 55 class showcase how much college has changed in less than a generation. '06: “This is probably the most difficult undergraduate math class in the country,” reads a page on the Mathematics Department Web site. '23: “Our slogan is, if you’re reasonably good at math, you love it, and you have lots of time to devote to it, then Math 55 is completely fine for you.” -- article published by the math dept titled, “Demystifying Math 55.” '06: Regardless of the course’s name brand value, Math 55 students face a single fact: It’s hard. Really hard. '23: Zoe Shleifer ’26, another current Math 55 student, also doesn’t get the hype. “It’s fun,” she says. “It’s just like any other class. You know, we go to lecture, and then we leave lecture, and then we do the problem set.” '06: Midway through October, the “Survivor”-like competition intensifies with the add/drop deadline looming frighteningly near, only five days away. '23: “We wanted to avoid a situation where some students felt excluded because of the way the course was taught a particular year,” (Professor) Harris says. '06: The class can’t stay this hard for this long, right? “I figure he’s just trying to get people to drop the class,” Litt says. He figured wrong. As class attendance steadily thins, the workload does not. '23: “To be as inclusive as possible is one of the things I was told before I walked in the classroom the first day,” says Harris. '06: Before the fifth Monday of the term, students who can’t seem to stay in the game start dropping like flies. “I thought it was completely unbelievable,” Harbater says. “Seventy started it, 20 finished it, and only 10 understood it.” '23: “The math department has been working hard to foster a more inclusive culture around Math 55. The overall feedback we have received from students about the last few iterations of the course suggests that this is beginning to bear fruit,” she continued, referencing reviews for Math 55’s Q guide reviews, which are overwhelmingly positive.

I am very saddened by this news. Niklaus got me into CS since I became fascinated by the beauty of his language designs and compiler architectures. And later he became the guiding mentor for my doctoral studies at ETH.
We lost a titan of programming languages, programming methodology, software engineering and hardware design. Niklaus Wirth passed away on the first of January. We mourn a pioneer, colleague, mentor and friend.

#Ukraine needs medical supplies for civilians. Currently there isn't enough supply and money can't buy something that isn't there. Trucks from Italy, Germany and Switzerland will be bringing supplies soon. Find how you can help in docs.google.com/spreadsheets…. #UkraineRussiaWar

Folks, public protests & posts are all very nice. And we appreciate them, truly ♥️ But the best way you can help #Ukraine _right now_ is this: Army: savelife.in.ua/en/donate/ Military tech support: armysos.com.ua/en/help-the-a… Medics: facebook.com/hospitallers/ (English in each post)

Since Thursday last week @Stripe Infrastructure and Security teams have been investigating the Log4j vulnerability. We’re happy that our defence in depth has protected our systems. We're sharing tools that help find vulnerable hosts and see if your mitigations are effective.
I’m proud of Stripe’s security and infra teams who have investigated and patched all our systems against the Log4j vulnerability since the moment the news dropped. Our pre-existing controls protected Stripe from any form of remote code execution.🧵

There's a lot of exciting engineering at @Stripe. We have high security, compliance, correctness, reliability, latency and efficiency requirements. All while empowering engineers be more productive than ever in their career. This creates impactful challenges. We are hiring.

Super excited about the huge milestone that team has reached. Building tools, processes and services that help product engineers focus on user needs helps Stripe deliver high quality product quickly. Stripe is hiring across both product and infrastructure teams!
We're big believers in multi-year infrastructure bets. After a few years of Ruby infra work, our in-house Ruby compiler is now 22–170% faster than Ruby's default implementation for Stripe's production API traffic. If interested in working on such problems, we're hiring!

Despite crazy transaction volumes over the holiday period and record growth rates, @Stripe API availability was 99.996% over the past 90 days. Proud of what our infrastructure teams accomplished last year and lots more global infra + latency improvement planned for 2021.
