Migrating Data Ingestion Systems at Meta Scale
Meta’s data ingestion system, which our engineering teams leverage for up-to-date snapshots of the social graph, has recently undergone a significant revamp to enhance its reliability at scale. Moving from our legacy system to our new architecture required a large-scale migration of our entire data ingestion system. We’re sharing the solutions and strategies that enabled a successful large-scale system migration, as well as the key factors that influenced our architectural decisions.At Meta, our
Building hybrid multi-tenant architecture for stateful services on AWS
Running a large-scale ad-serving infrastructure presents unique challenges when balancing tenant isolation with operational efficiency. Our infrastructure handles millions of requests per second and generates billions of dollars in annual advertising revenue, serving ads across multiple properties and systems. The cellular architecture problem Earlier, we had a cellular architecture where we allocated each AWS account with Application Load Balancer (ALB) and Amazon Elastic Container Service (Ama
Show HN: Gen AI's frontier of individuality
Hi- I hope you’re all having a good day so far! I'm not sure where to post this but I do have two things for you guys today, related to the AI space: individuality and a new era to AI! So:- LLM wrappers are crumbling- these businesses will not survive as foundational models begin to offer the functionalities consumers have been seeking. This maybe represents a failure in interpretation of individuality as horizontal growth (these startups didn't last too long...), which brings up the n
I designed Microsoft's EA channel in 2001. It's being dismantled in 2026
Submitter here, with quick context. I was the sole designer of Microsoft's Enterprise Software Advisor (ESA) channel architecture between 1998 and 2001. The model converted Microsoft's enterprise licensing channel from a margin-based reseller structure to a direct-billing, advisory-fee structure. It launched as part of Licensing 6.0 in October 2001 and is still referenced by name in Microsoft's FY2025 10-K twenty-four years later.The piece walks through what the original architec

Show HN: Shoehorn – Backstage without the maintenance overhead
I'm Anders, co-founder of Shoehorn (https://shoehorn.dev/).For about a year I was genuinely excited about Backstage. Saw the Spotify demo, thought "I want that too". Turned out it wasn't as easy. But to be fair, Backstage is a great piece of software. Powerful, flexible, and if you have a dedicated developer team to run it, you can build something amazing on top of it.The catch is exactly that: you need a dedicated team. Most companies don't have one. Or t
Show HN: Origami – A simple workspace-oriented terminal manager
Hey. Just wanted to show-off my project built with the help of AI/LLMs and share my experiences and clear myths I keep hearing and seeing about how AI will take over everything and everyone.I have over 10 years experience in software development so I guess I know a thing or two but of course people are free to form their opinions, these are mine. And they become much more apparent while working on Origami.- Coding with help of AI is not a one-stop shop, nor can you one-shot prompts for anyt
How to Secure Azure Databricks without Public Exposure using WAF + Private Endpoints
While first thing that comes up to mind is that lets configure IP Access List with keeping Azure Databricks in Hybrid Connectivity. This approach is technically doable, but not the best approach for organizations which follows Zero Trust Architecture Framework.This is where organizations has to design a solution which follows CAF Principles and is fully secured with Azure Application Gateway with Web Application Firewall (WAF) combined with Private Endpoints (Azure Private Link) becomes critical
Choosing between single or multiple organizations in AWS Organizations
Organizations face critical architectural decisions that can impact their operations for years to come. Recently, I had the opportunity to collaborate with a cloud migration advisor on a question that challenges many enterprises during their cloud adoption journey: Is it better to maintain a single organization or implement multiple organizations? This same question was also asked on re:Post. This question isn’t merely academic—it strikes at the heart of how businesses balance governance, securi

Show HN: Flow – Workflow automation that follows you across projects
Throughout my career I've worked on many different teams that often spanned many different projects and repos. Sometimes the tech stack was similar but naturally the tooling and development process grew in different directions. Whenever I onboarded onto a new project I'd spend a bunch of time just trying to figure out how to build, deploy, and maintain it. It was great when projects had an up-to-date Makefile or README, but that wasn't always the case. Sometimes developer runbooks
Show HN: Cyoda-go – application platform in Go without the Temporal/Kafka glue
This started out as an experiment. Reading Simon Willison's blog on where StrongDM was going with dark factories and Digital Twin Universeshttps://simonw.substack.com/p/how-strongdms-ai-team-build-se...I got thinking that, hey, what if we built a digital twin of our enterprise application platform Cyoda? With an in-memory local Cyoda service, it would make it much easier for people to get started building Cyoda apps, and rapidly speed up development.I also wanted to see

Show HN: wfb-link, a userspace WiFiBroadcast radio stack for macOS
Hi HN, I’ve been working on a Rust userspace radio stack for running WFB-style links from macOS using RTL8812AU USB adapters. Full disclosure: I'm a software engineer, but not really a hardware or embedded systems engineer, so Codex GPT 5.5 has done the lion-share of the work here along with a bit of help from Claude Opus 4.7 here and there. It's taken about 1.5 to 2 weeks to get from zero to this first release.macOS doesn't expose the monitor-mode / packet-injection path tha
Show HN: Prism – Self-hosted notification gateway (Signal, Telegram, WebPush)
As a de-Googled Android user, I wanted a way to privately receive push notifications from the apps and services I use. I already use several UnifiedPush apps, but I needed something for apps and self-hosted services that do not support it natively.So I built Prism and am officially joining a distinguished club of similarly named projects: the NSA's mass surveillance program, OpenAI's editor and two recent YC startups.What is it?Prism is a self-hosted notification gateway written in Go,
Conversation tree branching in @ably/ai-transport
Real conversations aren't linearPicture a developer pair-programming with an AI assistant. The model returns a function that almost works. The developer asks it to try again. The second attempt is worse. They want the first one back.In a linear chat, that history is gone, or it's a third bubble in the thread that pollutes context for every future turn. The same problem shows up when a user edits a message and wants to compare both phrasings, or when an agent picks a tool that fails and you'd rat

The model is fine. The session is broken.
Take any AI agent demo from the last six months. It works. Now ship it to real users on real networks, real devices, real attention spans. A meaningful share of those users will never finish their first conversation cleanly. Not because the model gave a bad answer. Because the connection dropped, the tab refreshed, the phone took over from the laptop, or the spinner kept spinning forever.Over the last year we noticed a pattern in our own customer base. A growing number of teams were building AI
