Codetown is a social network. It's got blogs, forums, groups, personal pages and more! You might think of Codetown as a funky camper van with lots of compartments for your stuff and a great multimedia system, too! Best of all, Codetown has room for all of your friends.

Uber introduced a high-throughput financial ledger processing system designed to handle hot account write contention at scale. Using 250ms batching, Redis coordination, and optimistic atomic updates, the system supports 30+ updates per second per account while preserving consistency and auditability, reducing multi-hour processing pipelines to minutes in its distributed accounting infrastructure.

To provide SRE as a service, a team built a center of excellence, introducing Federated SREs and roles like production manager and technical tribe lead. They created a culture of data-driven conversations where SLOs and SLAs were democratised. Surviving growing cognitive load meant continuously simplifying architecture and embedding sovereignty and resilience into platform design decisions.

The speakers discuss the architectural challenges of executing safe data deletion across distributed datastores. Balancing durability, availability & correctness, they explain how to orchestrate multi-system deletion propagation without impacting live traffic. They share lessons on controlling tombstone accumulation, building continuous audit loops, and gaining trust with a centralized platform.

Architectural change cases extend architecture decision record (ADR) thinking by evaluating how decisions may evolve over time. Change cases expose hidden assumptions and help teams estimate the reversibility and cost of change.

AWS disclosed that Resilient Network Graphs, a flat network architecture based on quasi-random graph theory, is now the default for most new data center builds. The design replaces fat-tree hierarchies with direct ToR-to-ToR mesh connections using passive optical ShuffleBoxes, cutting routers by 69%, boosting throughput by 33%, and reducing network power consumption by 40%.

Nick, Congrats on putting up the most readable, down to earth, factual profile I've come across to date. "Semi professional", regarding the profile photo, is a nicely humble remark you threw out about yourself and I must say, we're not in a glamour contest here (on earth ;-), at least most of us. You've got some very admirable skills under your belt and I suspect you've had some fun in the process.
I'm sure you don't know how superior James Ward's presentation will be at the upcoming GatorJUG. You'll be pleasantly surprised. It's going to be a world class talk, and I know because I have known and respected James for many years. To be honest, I think it's a pity more people don't come out to these presentations because I bring in some sharp speakers. I benefit personally, and it's nice that I get some tech savvy "for free" out of this. But, you might let people know that this is an opportunity to learn from true professionals, and it's a shame for anyone interested in software dev to miss it. Like, what I mean is tell your friends!
Looking forward to meeting you. The food's going to be good, too. Hand crafted stuff....stay tuned - you'll see! All the best, Mike
