The VOD for my BSC2026 talk "The Root of The Root of All Evil" is now available! It's the spiritual successor to last year's "The Big OOPs", so if you enjoyed that one, join me for one more adventure into the history of computer science: computerenhance.com/theroot

I did not sign this petition fwiw. Still not at all convinced that slower is safer than faster. With strong benevolent institutions slower is probably safer on net, but with our current crop it's a much more mixed bag.
We support this petition, signed by our CEO, several co-founders, and senior staff. Our own research on recursive self-improvement, published last month, points to the need for tools to deliberately pace the frontier of AI development so society can prepare. We’re glad to see broad agreement across the field. pacingthefrontier.com/

Something we learned through the creation of TigerBeetle: Static allocation is a forcing function for good design, good taste (and throughout your code base) as your team grows. The 2nd order value of good design, with realistic limits, trumps even the (many) performance gains.
Dynamic allocation / heap allocation is enemy number one. If your computer program is well designed, you should know how much resources it is going to take up before you run it. If you don't, then it isn't a good program Allocate everything on the stack

Introducing Claude Opus 4.6. Our smartest model got an upgrade. Opus 4.6 plans more carefully, sustains agentic tasks for longer, operates reliably in massive codebases, and catches its own mistakes. It’s also our first Opus-class model with 1M token context in beta.

opus 4.5 is really good at GPU programming, but somehow it’s even better at GPU programming jokes (h/t @Si_Boehm)

Finally, @AnthropicAI's @Si_Boehm and @bztree break down what it’s like running inference on NVIDIA GPUs, Google TPUs, and AWS Tranium, including architecture quirks, performance tradeoffs, and the tools they use to make it all work: youtube.com/watch?v=-k6yikkx…

Introducing Claude 3.7 Sonnet: our most intelligent model to date. It's a hybrid reasoning model, producing near-instant responses or extended, step-by-step thinking. One model, two ways to think. We’re also releasing an agentic coding tool: Claude Code.

Coookie banner is an example of a regulation that made everyone involved worse off. Such regulations should expire unless they prove their value.

THE LITTLE TECH AGENDA Marc Andreessen & Ben Horowitz July 5, 2024 Little Tech is our term for tech startups, as contrasted to Big Tech incumbents. Little Tech has run independent of politics for our entire careers. But, as the old Soviet joke goes, “You may not be interested in politics, but politics is interested in you.” We believe bad government policies are now the #1 threat to Little Tech. We believe American technology supremacy, and the critical role that Little Tech startups play in ensuring that supremacy, is a first class political issue on par with any other. The time has come to stand up for Little Tech. Our political efforts as a firm are entirely focused on defending Little Tech.[1] We do not engage in political fights outside of issues directly relevant to Little Tech. But we will fight for Little Tech – for the freedom to research, to invent, to create jobs, to build the future – with all of our resources. We find there are three kinds of politicians: * Those who support Little Tech. We support them. * Those who oppose Little Tech. We oppose them. * Those who are somewhere in the middle – they want to be supportive, but they have concerns. We work with them in good faith. We support or oppose politicians regardless of party and regardless of their positions on other issues. We are in this for the long haul. [1] a16z.com/politics-and-the-fu…

I wrote something: branchfree.org/2024/06/09/a-… - largely because I keep thinking about these different kinds of SIMD usage and writing the same Twitter posts. Mentioning, among others, work by @pshufb @lemire - oldish topics (been doing a lot of recent work that I can't share yet).

Software engineering is amazing. Startups sometimes fail to ship quality products due to lack of engineers (due to funding and budget issues) and big companies fail as a result of too many engineers working on same project (as a result of over funded teams).

America is under attack, I repeat, America is under attack Elon hit impossible goals, making shareholders hundreds of billions of $$$ Then someone with 9 shares sues, an insane judge rules against Elon, dismotivating him at Tesla, and the lawyers want $6B from Tesla?
NEWS: The legal team that voided Elon’s Tesla payout asks for a $5.95 BILLION dollar fee for winning the lawsuit.
