Joel Wynes Website - https://joelwynes.com/ Container platforms usually become complicated in a predictable place: not inside the container, but around it. A development team can package an...

Joel Wynes Website - https://joelwynes.com/ Serverless computing has always asked developers to adapt their applications to the platform. AWS Lambda made infrastructure management dramatically...

Most of the AI applications we interact with today operate primarily in the digital world. They generate text. Analyze documents. Write code. Produce images. Answer questions. Even when these...

One of the recurring tradeoffs in serverless architecture has been startup latency. AWS Lambda makes it remarkably easy to deploy event-driven application logic without managing servers. But that...

Most discussions about AI coding agents focus on what they can produce. How much code can they write? How many bugs can they fix? Can they build an entire application? Those are interesting...

Most operating-system permission models were created for applications. AI agents are something different. An ordinary application asks for access because it needs to perform a particular function. A...

One of the first instincts developers have when building something with AI is to improve the prompt. Add more instructions. Explain the edge cases. Specify the output format. Tell the model what to...

Seven days. That's one of those numbers that somehow became normal in subscription software. Why seven? Sometimes there's a good reason. Often there isn't. It's simply the trial length someone...

One of the most useful things we give software developers is permission to fail safely. Create a branch. Change something. Run it. Break it. Fix it. Try again. Production doesn't care until we're...

One of the conveniences of modern software development is that we rarely build everything ourselves. Install a framework. Add a few packages. Pull in an authentication library. Use an...

For years, one of the easiest architectural rules to remember about AWS Lambda was this: If the job might run longer than 15 minutes, Lambda isn't the right place for it. That rule influenced...

AI is quickly changing the software-development workflow. Agents can investigate issues, modify files, run tests, prepare pull requests and increasingly operate development tools themselves. That's...

One of the signs of good software architecture is something users will never notice: The infrastructure underneath the application can change dramatically while the application itself barely...

For the last several years, most applications of generative AI have followed a fairly familiar pattern. A user submits something. An application sends a prompt to a model. The model returns a...

Good product engineering is not simply about writing clean code, choosing the right framework, or shipping features quickly. It is about making technical decisions and product decisions reinforce...

Shipping quickly is usually treated as a sign of a healthy software team. More releases. More experiments. More customer feedback incorporated into the product. More visible momentum. But there is...

Software rarely becomes difficult to maintain because someone intentionally designed it poorly. More often, complexity arrives gradually. A product starts small. A few engineers move quickly, make...
