Codetown ::: a software developer's community
First of all, relax, I'm not announcing an exclusive executive swapmeet. The market for used cell phones has ramped up to a whopping $11 billion as of 2016[1]. That's a big number by itself, especially since the market scarcely existed just ten years ago. By comparison, everything sold in every category by everyone worldwide on Ebay, new or used, was $84 billion total in 2016[2].
Unless you are actually a senior exec and can offer your device, refurbished, to other employees then you have a couple options to pass along your once-glorious smartphone. Most of us in the US still sell back our devices to our carriers or directly to manufacturers. In other countries, especially Europe, (and for slightly older phones) people turn to sites akin to Ebay and Craigslist for quick cash. Or you could do what I do and strip everything down, install a paint app, remove the wi-fi password, and give the phone to your three-your-old.
Finally, I'd like to mention a gem in our greater Orlando, FL area: Computers Plus Cell Phones[3]. Having a local shop that offers up-front prices means you get even quicker cash and an honest human face. Full disclosure: their owner is a good friend of mine. You can even get a quote online before heading to one of their stores[4] and compare to your carrier's deal.

Chris Tacey-Green discusses the shift from synchronous commands to asynchronous events within highly regulated environments. He explains the critical role of Inbox and Outbox patterns in preventing data loss, the nuances of event versioning, and how to maintain decoupling between domains. He shares "battle-tested" principles for implementing fault tolerance and managing eventual consistency.

This article details our migration from Apollo Federation to a TypeScript-based tRPC stack, which resulted in an 89% reduction in bugs and 67% faster response times. It also covers the mistakes we made, the unexpected performance gains, and an overview of the production architecture we use today to handle 2.4 million daily requests with 99.97% uptime.
By Dinesh Kumar ElumalaiIn this podcast, Michael Stiefel spoke to Matthew Liste about building and managing software platforms. Platform services act as the basis for application development, and must always be stable, secure, and scalable. Scaling these systems is particularly difficult because unknown resource contention often causes them to break.
