🎉 Big news: Node.js is changing its release schedule for the first time in 10 years. From October 2026, less to remember and easier to know what's Current or LTS. Here's everything you need to know 🧵👇

Published another article for my Rust series Learn Rust Iterators by Building a Git Object Store Reader #rust #rustlang #programming blog.sheerluck.dev/posts/learn-...
Learn Rust HashMap and Iterators by Building a Git Object Store Reader | Mrsheerluck Blog
In this post, we are going to build a git object store reader in Rust and learn hashmaps and iterators in Rust

The article shows the new API side-by-side with the old one for every feature, plus a companion GitHub repo with every snippet ready to clone and run. I hope you'll like it 🙂 nodejsdesignpatterns.com/blog/whats-n...
What's new in Node.js 26
Node.js 26 ships the Temporal API by default, Map upsert helpers, Iterator.concat, V8 14.6 and Undici 8. A code-heavy tour with practical examples.

Node.js 26 shipped this week 🎉 My birthday is close, so I'm officially calling it an early birthday present from the Node.js team. 😂 This release doesn't look flashy at first glance, but the additions are genuinely useful in everyday code. I wrote a code-heavy tour, here's what stood out 🧵

@rustaceans.bsky.social hey John & Elley, big fan of your newsletter here! I hope you'll consider my last article loige.co/writing-midd... for your next issue :) It's a pretty long one but hopefully it covers Tower in a way that can be useful even to folks who don't target AWS Lambdas (yet).

In my latest online course, I cover the fundamental integration patterns you will see most often in #serverless applications.. And this isn't just point to point vs pub/sub. This course covers a range of different #patterns, and importantly, how you can actually use these patterns in #production.
Serverless Integration Patterns
Learn practical knowledge for implementing integration patterns with AWS serverless services. This course goes far beyond what is in the Enterprise Integration Patterns book

For the past 9 years, I have been running a newsletter called FullStack Bulletin. Every week, I shared some of the most interesting articles, tools, and resources I could find for full stack developers. Over time, that became 450+ issues, 3k+ curated links, and a community of 3k readers.
New blog post! I added Bluesky likes and liker avatars to my #Astro blog. No API keys, no server-side code, just pure delightful #webcomponents. Here's how I went from "I want that" to "it's live" in about an hour: loige.co/how-i-added-...

1/7 🚀 Getting an LLM demo to work is not the hard part anymore. The hard part is making it reliable, predictable, and affordable in production. That’s what @eoinshanaghy and I focus on in the latest AWS Bites episode, all about LLM inference with Amazon Bedrock 👇
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

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?...

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
