- [I'm Done Making Empty Promises](https://daily-devops.net/posts/code-as-legacy-empty-promises/): // TODO: fix this properly. We'll refactor after the release. Tests when the API stabilizes. I've made every one of these promises. I'm done.
- [My Biggest Enemy Writes My Code](https://daily-devops.net/posts/code-as-legacy-past-self/): Past Self is the most dangerous engineer on your team: skilled, well-intentioned, and gone when the bill comes due. This is about the code he left behind.
- [Six Ways ILogger Silently Fails in Production](https://daily-devops.net/posts/your-ilogger-is-lying-to-you/): Half a day lost to BeginScope silently doing nothing in production. ILogger compiles, runs, produces no errors, and fails quietly in six distinct ways.
- [The Code You Write Today Is Someone's Problem Tomorrow](https://daily-devops.net/posts/code-as-legacy/): Code is not just something you write—it is something you leave behind. After nearly two decades in production, here is what treating code as legacy means.

- [Source Generators: The Build Performance Killer](https://daily-devops.net/posts/dotnet-source-generators-hidden-costs/): You added a NuGet package and your build jumped from 2 to 8 seconds. That package ships a source generator. Here is what it costs and how to find out.
- [Green Dashboard, Dead Application](https://daily-devops.net/posts/health-checks-operational-monitoring/): HTTP 200 from /health while users see timeouts. The process runs, but the database pool is exhausted. Check what matters, not if it breathes.
