looking forward to our new role as boutique software plumbers 🙂 Excellent article from @matteocollina adventures.nodeland.dev/archive/softwa… @loige

@mitchellh For a moment I thought DnD was dungeon and dragons... 🥲

This is how you get dumber btw, true even before AI. Turn on DnD, put your phone in a drawer. The best option if you can is to separate work + personal devices so your work device can't even see personal stuff. This is also partially why Pomodoro was all the rage a decade+ ago.

7/7 🎙️ So if you are experimenting with LLMs on AWS, or trying to move from prototype to production, this episode should be useful. Listen here: awsbites.com/153-llm-infere… Curious to hear your biggest Bedrock lesson so far 👀 #AWS #AmazonBedrock #LLM #GenAI

6/7 🧱 One topic I find especially important is structured outputs. If you want to integrate LLMs into real systems, free-form text is often not enough. You usually need something predictable, parseable, and robust, like JSON that actually follows a schema.

1/7 🚀 Getting an LLM demo to work is one thing. Getting an LLM feature to be reliable, predictable, and affordable in production is a very different game. In the latest AWS Bites episode, @eoinshanaghy and I talk about running LLM inference with Amazon Bedrock 👇

@ellie_huxtable Well deserved! 👏

we're trending on github! ⭐️

@orhundev Wooow! Thx for sharing

Are you using Homebrew? Sorry to hear that, check this out: 🍺 zerobrew — A modern drop-in replacement for Homebrew on macOS 💯 Content-addressable store + parallel downloads = 20x faster 🦀 Written in Rust! ⭐ GitHub: github.com/lucasgelfond/z… #rustlang #cli #devtools #macos #homebrew #packagemanager #performance

@RahulRaghav_10 @FrancescoCiull4 Check this one out: maxday.github.io/lambda-perf/ :) All the code is open source if you are curious to see the details!

@FrancescoCiull4 @loige curious how the rust implementation compares to node.js in terms of performance

🛑New video In this one, with the help of @loige , we will show you how to create, build, and deploy a Lambda function on AWS, of course, using Rust. We also talk about different implementations using other technologies, like Node.js and Python Video link below.

@astuyve ... I thought 51.09M was the number of recruiters! 🥲

cooked up a sweet little OpenClaw dashboard. It monitors logs, processes, approvals, and errors. It even keeps track of how many recruiters I've declined:

@FrancescoCiull4 @annanidev Actually, this website is some fantastic piece of work by @_maxday ! Let's give credit to who really deserves it ❤️

@loige @annanidev luciano to the rescue!

@annanidev @FrancescoCiull4 Check out this one ;) maxday.github.io/lambda-perf/

@FrancescoCiull4 @loige Rust on Lambda is such a vibe. The cold start performance comparison with Node would be really interesting to see though.

Link: nodejsdesignpatterns.com/blog/nodejs-pa… If you work with file paths and user input in Node.js, this one's for you.

I wrote a guide on preventing path traversal in Node.js: ✓ Why path.join() won't save you ✓ Attack vectors (double encoding, null bytes, symlinks) ✓ A safeResolve() function with detailed explanation ✓ Lots of code examples ✓ How to test it

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 🧵
