{"canonical":"https://www.readysetcloud.io/newsletter/238/","categories":null,"contentText":"🦸 Community Superhero Our community superhero this week is Eyal Estrin, VP of Cybersecurity at JPMorganChase. Eyal is a prolific writer, having published two books on cloud security and dozens of articles on his blog. I’ve been reading his content for years, and love his grounded approach to security and the cloud. He’s also a recent winner of the Global Ignite Award for community leadership. Thank you for everything you do, Eyal!\n💯 Spotlight I always enjoy the AWS blogs that share the numbers from Prime Day. The numbers are astounding and the scale often doesn’t register in my head. But something understated in the blogs that I really like is how much AWS relies on serverless. Between Lambda, DynamoDB, SQS, Kinesis, and half a dozen other serverless services, it goes to show that serverless really does scale - because there aren’t really other events that hit this kind of prolonged scale. Renato Losio wrote up a great analysis on the ten-year progression of Prime Day where he breaks down the numbers and offers some revealing insights about how this event has been able to scale up the way it has. It’s crazy to see the numbers all together like this. I love it. It’s an inspiring read.\n🔥 My Favorite Content My favorite mad scientist, David Behroozi, published an article last week describing how he shrank the LLRT binary size to reduce cold starts for his Lambda functions. David walks us through all the steps he took, from removing unnecessary SDK dependencies all the way to removing modules he doesn’t take advantage of in his function code. This is some pretty advanced engineering, but if you’re trying to eke out every millisecond of your Lambda functions, it’s well worth the read.\nIt’s hard to follow David, but I’ll try. I published a write-up of a fantasy football app I made that lets me compete against AI agents. The article is much less about fantasy football, and much more about the neat concepts I was experimenting with to make agents have persistent intent. I found that having the agents wake up to discover league state over and over again was a recipe for disaster. So I started giving them agenda items and made them track commitments to pin long-running objectives to the top of their attention. It’s working so far! Maybe a bit too well, I’m currently in second-to-last place 😅\nAnd of course, the week I talk about the game I made, I get one-upped by the godfather of Lambda himself, Julian Wood. Julian was able to get Doom running in newly released Lambda Web Functions. Julian walks through his design considerations, which are pretty neat, and describes how he gets around game state across execution environments. Spoiler alert - it works great! I tried playing it a bit, and while I didn’t get very far, I did have a seamless experience. So cool!\nHere’s my weekly reminder to keep your voice with everything you create. Last week, Steve Huynh wrote a potentially polarizing blog post on the death of Amazon’s writing culture. If you aren’t already familiar with Amazon’s culture, this is a good peek into it. For those who are aware, this is a sad reminder that AI is disrupting everything, and not always in a good way. He talks about how AI has degraded a superpower at Amazon and offers his thoughts on what would save it (and what you should adopt where you work). He also references Sophie Alpert’s AI writing policy, which I covered in issue 229 and is worth revisiting.\n💡 Tip of the Week I found Sean Goedecke’s take on software quality at big companies spot on. I worked at a large enterprise for most of my career, and everything Sean points out is exactly right. It’s a hot take, but also kind of not. I found this an entertaining read that had me nodding along the whole way. Curious what y’all think!\nLast Words We were all over the place in this issue, but that’s a good thing. We have some phenomenal writers posting content and I love hearing such a wide range of voices on a diverse set of topics. And if you’re just getting into writing and want to see your content shared here, please reach out to me so I can take a look!!\nThat’s my take on the week, but what’s yours?\nWhat did I miss? What made you nod along (or 🙄)? Hit reply if you’re reading the email. Prefer socials? Ping me on Twitter, LinkedIn, or email.\nHappy coding!\nAllen\n","date":"2026-10-19T00:00:00Z","description":"Turns out you can run Doom on a Lambda Web Function... who knew?!","image":"https://www.readysetcloud.io/images/newsletter.png","inLanguage":"en-US","lastmod":"2026-10-19T00:00:00Z","readingMinutes":4,"section":"newsletter","tags":null,"title":"Here comes the Doom (but in a good way)","url":"https://www.readysetcloud.io/newsletter/238/","wordCount":765}
