I got a number of questions on how we saved $30k a month on cloudwatch by moving logs directly to S3/Iceberg with Postgres so I wrote up how in a bit more detail - https://t.co/4F7kwv4Oz8

[Gwen (Chen) Shapira @gwenshap]

Auth has to be *systematic*

All the bits:
- Pages, components and forms in the browser
- Backend endpoints and validations
- Database access control

It all has to work together. Or your app won't be secure. 👇

Vibe-coders:
Make sure you instruct your favorite LLM to use an auth library with CSRF protection from password hijaking, and ask it to use CSRF protection on every sensitive route.

I've been hearing a lot about different programming workflows to make full use of LLMs, but I want in-depth accounts of how it works. This blog by @harper is exactly what I've been looking for.

While the computer science field of automated reasoning is rooted in the work of Socrates and Plato from thousands of years ago, @awscloud is the first and only cloud provider to use this technology in a way that gives our customers assurance in the correctness of generative AI.

Our mathematically sound Automated Reasoning checks add a more rigorous and verifiable approach to making sure that LLM-generated output is factually accurate. By encoding your enterprise domain knowledge into structured policies, customers can have confidence that their conversational AI applications are providing reliable and trustworthy information.

🚀 AWS Lambda Developers, take note! AWS just leveled up local development with powerful enhancements for VS Code users. Let's break it down! 🧵👇

[Gene Kim @RealGeneKim]

I’ve mentioned how I’m starting to believe that GenAI making coding tasks faster is the least important metric. Implementation is just one part of creating software. Just as important (and maybe even MUCH more important) is the research, design, and exploration of options. I’m blown away by how GenAI can dramatically increase the ability to explore options, and defer having to make decisions. These decisions are so consequential before they are often “one-way doors”, where we have to commit to it, often given very imperfect or incomplete information.

Dr. Robert Merton earned the Nobel Prize for Economics (along with his colleagues Dr. Fischer Black and Dr. Myron Scholes) by observing that as uncertainty increases, the value of deferring decisions also increases. I was talking with @Steve_Yegge yesterday, and I shared with him my recent experiences playing with https://t.co/hBLlVYpisB from @stackblitz — I was surprised how easily I was able to experiment and implement numerous authorization services. In 45 minutes, I had a working app that had authentication working with Google Oauth working with Auth0, Firebase, and Supabase.

I never used any of those services before. Although it wasn’t exactly free of frustration, I’m sure that it would have taken me one day for each service in previous years. (And each day would have been so exhausting, I think I would have settled for whatever I had working — no energy left for exploring other options.)

(I've implemented OAuth maybe 5-10 times in the last 15 years. And I still barely know how it actually works.) I think it’s difficult to overstate the value of being able to explore three options, and defer a decision until I had actually tried all three. Yegge’s reaction: “In the past, these decisions were so consequential, they were basically one-way doors, in Amazon language. That’s why we call the ‘architectural decisions!’ You basically have to live with your choice of database, authentication, JavaScript UI framework, almost forever.

"But that’s changing with LLMs, because you can explore, investigate, and even prototype each one so quickly. Even technology migrations are becoming so much easier/cheaper/faster. “These are all examples of increasing optionality.” I love his observation of architectural decisions — because once you make it, it’s basically like you’ve buried yourself in concrete, and it will take a monumental effort to undo / redo it in the future. Imagine the value of driving that down by orders of magnitude.

Amazon CEO @ajassy reminisces about how AWS re:Invent—our biggest cloud technology event of the year—all started. #AWSreInvent

[AJ Stuyvenberg @astuyve]

AWS just announced Aurora DSQL - a purpose built, postgres-compatible serverless database and take it from me - it's amazing.

I've had a few months to play with it (more soon), but it's truly the single most exciting launch I've seen from AWS in a while.

You've gotta try it

[Andy Jassy @ajassy]

It’s been three years since I was last at #AWSreInvent and excited to be back.

Am going to try doing a few low-key videos this week on recapping what I’m excited about and what we’re hearing from customers. Will start this series with a little reminiscing about the origin of AWS re:Invent.

Intend to share some thoughts on some launches tomorrow.

[Gwen (Chen) Shapira @gwenshap]

Finish the week with a Postgres video 🌟

All about using JSON in Postgres:
- when you should use it
- how to use it efficiently
- how JSONs actually get stored in postgres.
