@ashishlogmaster I like that idea! I gave it to an agent to investigate. The indexing is likely better suited to Lambda because it needs a lot of CPU and memory. But serving the contents of individual files is perfected suited to Workers. I'll dig further. Thanks for the idea :)

AI has made my abandoned "browse any Docker image" website side-project useable. It now indexes images twice as fast, files can be deep-linked, og:images, and the ability to view only hidden files. E.g. here's a file left behind in a CodeBuild layer. ima.ge.cx/public.ecr.aws…

AWS just enabled scalable network bandwidth, so now the perf has increased again. It now indexes a 6.52GB image in 16.5 seconds instead of 43.7 seconds.

AI cut indexing time in half, but now the limiting factor is network bandwidth. AI asked AWS to enable scalable network bandwidth. It's now checking on that request every hour. Then it will experiment with perf in dev while I sleep and push to prod once validated. What a world.

@zackkanter @diegosantiviago It’s not quite a Rust runtime, but it might get the job done until that arrives x.com/__steele/statu…

Lambda Web Functions aren't strictly limited to only Node.js, despite what the docs and launch blog say. You can instead run Go (or Rust) on them and save money through better CPU and memory utilisation, and easier multi-threading. 3/4 awsteele.com/blog/2026/10/1…

@myonlinetrust Honestly I didn’t even try that and it might work. It would certainly be a lot simpler if it does. I just assumed that the CPU would be suspended when the number of inflight requests hits zero. I’ll check tomorrow morning AU time if you haven’t already got the answer by then

Lambda Web Functions were released today. I got carried away and wrote three blog posts about them. 1: A collection of technical tidbits. 2: They're not actually Node.js-only, you can run Go/Rust. 3: They're cheaper than Event Functions at processing events. 1/4

Finally, Lambda Web Functions as queue consumers. Regular ("old") Lambda functions have been repositioned as Event Functions, but you can handle events with Web Functions too. The secret ingredient is EventBridge Pipes. It even works out cheaper! 4/4 awsteele.com/blog/2026/10/1…

@apparentorder You beat me to it! I was just about to publish a blog and I see you’ve covered half of it. I mentioned the predecessors too 😁

@angerman @ProgrammerDude This is really cool, thanks for building and sharing. Can’t wait to try it out

@dannolan It was just so good. I told one thread to reboot the Mac mini (to test recoverability after power loss) and it sent a message to all the other running threads telling them to pause their work and waited for ack before proceeding. And sharing threads with colleagues - so good.

I know I've fanboyed about Amp before, but it just keeps getting better. This weekend I bought a Mac mini and got Amp to set it up as my new Amp runner + GHA runner. The macOS app is great, and I love the desktop sharing. Subthreads are so good. And now Claude subscriptions too!

@gbrl_dick @KarenFuchs16 @ChrisOfTheFens I’m Australian. Visit the US 4-5 times a year. Always have a bad time in a way that visits to China and Africa never touch. But I also realise it’s entirely self-inflicted (for me). I have a morbid desire to try the most American food I can find and overdose on HFCS every time.

@dannolan Just put your UDP traffic on port 53 and it won’t be blocked! (People dumb enough to do this to UDP won’t be checking if udp/53 is actually DNS packets)

@dinodaizovi @anton_chuvakin Fast pipelines were always a good thing because delays lead to batching changes (to avoid frustration) which lead to riskier deployments. Now they’re good because Amdahl’s law means they’re usually the limiting factor to how fast agents can improve a single codebase.

@taipan168 @JaneEOpie This is what I do. Work pays for premium economy and I use points to upgrade to biz. I choose the QF A380 where I can, because it has more biz class seats than the 787 — I reason that gives me a better chance at upgrading. Works about 80% of the time

This is a really nice improvement: you can now include EC2 resource tags in VPC flow logs. I wrote a poor version of this about 8 years and 3 jobs ago. It's infinitely more useful than raw IP addresses for making sense of east-west traffic. aws.amazon.com/blogs/networki…
