ttul··on SlopCodeBench 10/2026 – Opus 5.5, Astra wins overall, xhigh considered harmful
I've noticed the line breaks issue. It's easily fixed with a formatter like prettier and, frankly, that kind of quality-of-life thing is best handled deterministically anyway.

Surely they mean Opus-5.5...
ttul··on Mercury 3: Diffusion at scale
Super cool. I'll have to give it a whirl! Keep up the amazing work.
ttul··on I no longer care to work on any Ruby gems so I've archived all my repositories
I am inclined to think this way in a commercial setting, but for open source contributors, where their work was done for the love of coding, I can understand feeling like the end has arrived. In my company, I'm building the mechanics of factory-coding and trying to get the team think in higher-level terms: what needs to be built, what does it need to do when it deploys, and how can we build the factory that gets that done repeatedly? To me, building the factory is an interesting problem and agentic coding does not eliminate the higher-level design that absolutely must be done, all of which is, to me, the interesting part of software dev.

But none of this is going to bring back actually writing code for the love of it. That will become a hobby kind of like knitting or sewing.

I'm curious if you could comment on why your DeepSWE performance is below Haiku. This is not a dig - getting 46% vs. Haiku's 52% is still amazing. I'm just wondering if perhaps your post-training was less aggressively RL'ed on coding tasks than perhaps Haiku was. Having a cheap 1,000 tok/s option for coding work is a dream because - if it's reliable enough - you could blast through work such as high-level security reviews or finicky and repetitive refactorings that don't necessarily require SOTA performance.

I was chatting with a friend who commits on a very well known open source project (~80K stars). He is disillusioned not because the robots aren't good at what they do -- they totally are. The sad thing is that he enjoyed writing code and working with the community on improvements because it was a very human, collaborative thing to do. So, while the robots are great at pushing the project forward even faster and doing fantastic things for security and performance, the joy is gone.

I can totally identify with that feeling. It must be how professional mathematicians are feeling as well.

ttul··on DeepSeek search and fetch – $0.75 per 1000 successful requests
It's a little more involved than just having proxies in Pakistan. I'm quite sure Google has some protections against bots and scraping and SerpAPI's team unfailingly seems to work around those restrictions.
ttul··on Someone behind the software
Agentic coding lets you build more things in less time. Companies have responded by ordering product teams to pick up the pace of releases. But the bottleneck isn't coding execution, it's choosing what to build and verifying that what got built doesn't suck.

I think this problem will be solved. Frontier models recently learned how to do 3D really well (Astra was first on 3D; Opus-5.5 nailed it weeks later). How long before they get trained up on product management? It won't be long. Sorry.

ttul··on Development statistics for the 7.2 kernel
I'm serious. Linus does not rule Linux because of some cabal of dark overlords. He leads because he continues to deserve the job. I think Linus would be the first to admit it's time to retire if he started failing in his leadership of Linux development. That being said, there is truly nothing standing in the way of anyone forking the kernel and building their own version, over which they have complete control. So, I think it's an entirely fair suggestion to make.

SerpAPI is comically good at evading Google's scraping protections. If what you want to know is, precisely, what someone searching Google in Pakistan would see, this is the API for you.
ttul··on Will it be a golden age or a dark age for mathematics (and science)?
My read on Terence Tao's comments of late is that professional mathematicians are principally upset about AI-submitted math papers lacking the kind of broad teaching content that high quality human math papers offer. While the answer might be correct, AI math papers don't teach the reader in the way a human author would have. Professional mathematics is not just about solving problems; it's just as much about spreading knowledge so that others can program their human brains with the same understanding that the paper's author had when they wrote the paper (and achieved the result).

In other words, the crisis in mathematics (as I read it) is that AI can solve without teaching. The result may be impressive, but if the only beings that can move math forward in future are machines grinding away on billions of scenarios that no human would have the patience to undertake, this leaves those in the profession wondering about their place in it.

I suppose, feel free to fork the kernel and take the lead?
ttul··on Fire at Starlink site in Bulgaria after suspected sabotage in Poland
At least one betting market has the odds at around 25% [1] of a direct military conflict with a NATO country by year's end. It will be interesting to see how things change after November's midterm elections. For what it's worth, Metaculus forecasters show a spike of likelihood at the end of September, 2027, with about 20% of forecasters saying that's when a military clash will happen. I'm not sure what's driving that spike in the forecast.

ttul··on Incident with Actions, Pull Requests and Issues
2 billion per day is 23,148 per second on average. Perhaps peak bursts are >100K per second. That's a seriously insane number to keep up with at GitHub's scale. I've worked on systems that write >100K things per second and when it has to be globally distributed and relatively consistent within seconds, that's a very tough challenge.
ttul··on Passkeys are a trap
TOTP is susceptible to man in the middle attacks. Passkeys are not. That alone is a solid reason to favor Passkeys!
ttul··on The gap in shared understanding of LLM capability is widening
I should frame this for the wall behind me when I run meetings with my team. It’s the core problem with AI in coding.
ttul··on Rolling the Root Key
Dan Kaminsky told me about the signing ceremony years ago (bless his heart, he was one of the people trusted with DNS security). Apparently, everyone on the signing committee flies to a central location carrying a hardware key. Then they take turns inserting their hardware key into a hardware security module. It's all done face-to-face because that's the only way to guarantee that human consent was granted properly at each step.

Each ceremony is recorded on video and distributed to the public. The last one was in August, 2026: https://www.youtube.com/watch?v=-QqYS3oLfL8&t=1s

ttul··on Talorys – A self-hosted personal AI agent on Cloudflare's free tier
Thanks for clarifying. Not sending a warning for a $34K bill is pretty terrible. My company runs a service that allows larger customers to run overages and all of our bad customer experiences have stemmed from surprise overages that we failed to warn them about. Over the years, we have learned to be less stupid about that!

It appears that even very large companies like Cloudflare may need to brush up on customer experience from time to time.

A $34K bill with Durable Objects implies they somehow made 227 billion requests in a month. Sure, if that's the kind of traffic you're serving, your bill ought to be $34K! That's 87,000 per second!
ttul··on Talorys – A self-hosted personal AI agent on Cloudflare's free tier
Durable Objects are the coolest thing I have seen in a while. Code and its data locked away together, frozen when not in use, but ready to go in milliseconds when a request comes in. They are so damn useful.
ttul··on Typesafe AI raises $870M at $7.5B
But Jev established the branding and investors are betting that Jev will be acquired by one of the big labs soon - and if they aren't, the money itself can create a positive outcome by allowing Jev to hire incredible talent and scale the company rapidly.
ttul··on Cloudflare acquires Deno
Fundamentally this acquisition is not about Deno the open source project. It’s about buying an amazing team that has built a self-hosted version of Cloudflare Workers that actually doesn’t suck. And that is all about commoditizing the complement.

Deno built celld, which implements the Workers and Durable Objects programming model with self-hosting in mind. Cloudflare says its own distributed infrastructure is too complicated for straightforward self-hosting, and it hadn’t successfully solved that problem. For customers who might be reluctant to commit to being locked in to Cloudflare’s infrastructure, having a rock solid self-hosted alternative reduces that reluctance.

ttul··on Why isn't the industry freaking out about DeepSeek 4.1 Flash?
Stanford tracks RAM prices in this nice little site: https://dam.stanford.edu/memory-prices.html

Costs did go nuts, but there are signs of easing in the market of late. CXMT is starting to have an impact and priced will probably fall in 2027.

ttul··on Tell HN: Uceprotect is extorting website owners
Spamhaus does not offer the ability to pay for removal. UCEPROTECT is uniquely evil in insisting on payment. It's a good thing that their lists are not widely used, so, in practice, it doesn't matter if your IPs are listed by them. Their revenue comes from unwitting victims who don't know any better.
ttul··on Web Search API
I think their strategy is: "AI coding means we can build everything. Our infrastructure approach is incredibly quick to build upon, so why not build it all ourselves and then anyone with half a brain will move their stuff to Cloudflare and leave AWS in the dust."
