I almost approved a security hole last year. A simple image server. Clean code. Worked perfectly. It also let anyone read any file on our filesystem. Here's what happened 🧵

Confession: my fingers still type `npm i axios` on autopilot from time to time 😅 ...And yet… Node.js has shipped a built-in `fetch()` since v18 (2022)! Still, I keep running into the same questions: - Should we use it? - When is it a good fit? - How do we avoid the usual footguns?

Thrilled to announce chapter 09 of the Rust Lambda book. In this one, we cover all things observability. If you're struggling to really understand your serverless applications, this one's the one for you. @loige.co 👀 #serverless #rust #rustlang rust-lambda.com

I filled out the 2026 #AWS @Answers4AWS survey. You should too! answersforaws.com/survey/ #aws

AWS Lambda just got less #serverless 🚨 @loige.co and @eoin.sh explore Lambda Managed Instances - #Lambda functions running on #EC2 We built a video processing app to test it. The verdict? No more cold starts (kinda), concurrent invocations, and a new scaling model! ➡️ youtu.be/i-Nr0cqrdDk?...

I love reading all your annual summary blog posts. Send them my way. pawelgrzybek.com/a-look-back-... So far I have @dbushell.com @bell.bz Cory Dransfeldt @hidde.blog @css-tricks.bsky.social @chriskirknielsen.com Damian Walsh and @loige.co on my list. Send some more my way please! #blogging

As 2025 comes to a close, I just wanted to wish you a great end of the year and a fantastic start to 2026! 🎆

I’m a bit late with this one, but better late than never ⏳🙂

Ever deployed an API Gateway HTTP API with a JWT (OIDC) authorizer, got a nice green “deployment succeeded”… and then discovered that routes mysteriously disappeared in the console and auth wasn’t working? 😅🔐

🗞️ New release alert: Crafting Lambda Functions in Rust 🦀⚡️ A practical, work-in-progress book on writing super-performant AWS Lambda functions in Rust, co-authored with James Eastham. #RustLang #AWSLambda #Serverless

@buttondown.com I have been absolutely loving your service so far! For context, I am using it happily for fullstackbulletin.com One of our readers has recently reported that some Fortinet deployments block your click tracking domain (see attached picture). Is there anything you can do to about it?

Ever love AWS Fargate… until you suddenly need more control? 😅 GPUs, storage options, network bandwidth, specific instance sizing…

Rust on AWS Lambda is now GA 🎉🎉 To celebrate @loige.co and me put together a short newsletter and talked about what's next for the next two chapters of the Rust on Lambda book. And some details on the next release.... news.rust-lambda.com/p/from-exper... #serverless #rust #rustlang

Node.js friends, quick heads up! 👋 Today (13 Nov 2025) I am doing a live AMA with Mario Casciaro, hosted by Packt, all about Node.js Design Patterns (4th edition) and how Node.js has evolved over the years. #nodejs #javascript #ama

Did not see this coming: #Canva made #Affinity free and is investing to revamp it. Smart growth move and a win for creators... pro-grade tools for free. First look: www.youtube.com/watch?v=CzPz... #Design #AffinitySuite

Here’s a story I didn’t expect to write 👇🧵 (1/8) A few days ago I went down a rabbit hole to see what people search most about Node.js. Guess what? “how to read and write files” is near the top.

You know you have been away for too long from a project when a `git pull` on `main` takes more than 2 seconds and you get hundreds of file changes! 🤨 #git #devlife

Level up from dev → architect? Check out James’s latest Dometrain course: modular monoliths, events, C4, observability, ADRs. Even if you’re not into .NET, you'll get tons of value from it! 🚀

A great opportunity for anyone who wants to actively contribute to the success of #RustLang! And working with @ieni.dev is just an extra perk 😉

🎉 Author copies are in! 📚 Holding the 4th edition of “Node.js Design Patterns” never gets old. Months of work turned into something I can touch, and hopefully a guide to help you level up with Node.js.

Have you heard about #Strapi, an open-source headless CMS? It lets marketing teams manage content independently while developers maintain full control over the frontend. @eoin.sh & @loige.co discuss its powerful features and share #AWS self-hosting tips in #AWSBites 🎙️ awsbites.com/149-headless...

Un libro molto interessante e ben fatto, caldamente consigliato

Think #Java & #serverless don’t mix? This week on #AWS Bites, @loige.co is joined by Mark Sailes (ex-AWS serverless specialist) to tackle that myth! Learn when Java on Lambda works (and when it doesn’t), how to hit real latency goals, and which levers matter in production. youtu.be/jjE0hMkXazE?...

Stuck keeping #Spring apps alive on #EC2 or herding #Kubernetes just to ship a few endpoints? ⚙️ What if #Java on #AWS #Lambda could hit your latency targets and cut the ops tax too? ⏱️💸

Just made my first contribution to #Nextjs! It’s a small docs fix, but hopefully it’ll save someone a bit of time down the road: github.com/vercel/next.... Big or small, every contribution counts... that’s the power of open source! 💪 #Nextjs #OpenSource #DevLife #JavaScript

🚀 New AWS Bites episode! We tried Amazon #DSQL so you don’t have to (but you might want to) 👀 Luciano and Eoin put Aurora DSQL through its paces in #AWS Bites #Podcast Episode 145 🧵 Here’s what we found:

Internal platforms are meant to help engineering teams. BUT they can also become a burden. The platform trap is real. Complex systems can be harder to maintain than the apps they support. Well-meaning abstractions can turn into heavy loads.

How do you hash… a banana? 🍌🤔 I spent 20 minutes trying to figure out why hashing "banana" with SHA-1 in Node.js gave me a different result than doing it in the terminal. A classic case of “invisible bytes”! Let me walk you through it 🧵

TypeScript excitement 😉 Congrats to @searyanc.dev on landing big updates to the default tsconfig settings used by `tsc --init` 🎉 Defaults matter - and in TS 5.9 they embrace simplicity 💙 🔷 ESM (was CommonJS) 🔷 No down-leveling (was ES2016) 🔷 verbatimModuleSyntax: true github.com/microsoft/Ty...

I reviewed this edition, and what was already a must-read book is now a mandatory read. I highly recommend it to seasoned developers as well.

📘 The new edition of Node.js Design Patterns is coming soon! After 9 months of hard work with Mario Casciaro, we're finally ready to share what’s next for one of the most loved Node.js books. But this is not “just another edition”...

🦀 Going live in a few hours! @francescociulla.bsky.social is hosting a #RustLang stream with me, @lpalmieri.com and @ieni.dev. We all come from different backgrounds. Join us to hear what brought us to #Rust and what keeps us using it. 📺 www.youtube.com/watch?v=niD8...

My friendship with #ChatGPT is built on mutual trust 💖, deep respect 🫱🫲, and me yelling “NO EM–DASHES” every 2 messages 😤 It nods, says “Got it!” 🤖 Then casually drops another one or two... like nothing happened 🙃 I guess there are too many em-dashes ended up in the training data...

Think you have impostor syndrome as a software engineer? Try martial arts 🥋 Nothing like getting your first belt… and still feeling like you know nothing. Then comes the next belt. And the next… and the feeling doesn't go away. Confidence isn’t a destination. It’s a practice.

Today on #AWS Bites, @conzy.bsky.social joins @loige.co to chat about migrating a monolithic app from on-prem to the cloud — using #AppRunner instead of #Fargate. Does App Runner live up to the hype? We cover pros, cons, and when Fargate might still be the better pick. 🎙️ youtu.be/Phc3ifgB1c8?...
