A non-trivial danger of being an older developer is erroneously believing that something new is just like something you knew a decade ago when it’s not, or missing how newer technology might be making an “old” technique more viable than ever
hardest part about growing old in software dev is seeing the cycles, deliberately opting out of the treadmill, while listening to breathless excitement about the current thing you learned has legit tradeoffs …about a decade ago… and remaining polite about it

I don't get the angst over C# getting some modernizations. They make it plenty easy to lock the language usage back to a certain version in your codebase, the changes have done a *lot* over time to reduce code ceremony, and learning new things is pretty well a job req for us

Seems like a good explanation of exactly why Biden said what he said.
Fleischer: When he said that Israelis should not be consumed by rage? Who the hell does he think he is? I sat in on every summit meeting with foreign leaders when they came to the US after 9/11 and met with Bush. Not one said to Bush the Americans shouldn't be consumed with rage

Overkill for small projects, horrendous for complicated projects with deep business logic. Maybe only truly helpful for medium sized CRUD centric apps.
When should you not use Clean Architecture?
Clean Architecture is designed for complex systems with multiple layers and components.
If you have a small, straightforward project that doesn't require much separation of concerns, using the Clean Architecture may be overkill.

Funny, I’m recommending a client start to rip this strategy out of their codebase because of the extra complexity, code noise, and overhead it adds.
Here's a simplified Result class implementation that I use in my projects.
I use it to make it explicit that a method can fail. The result carries an error describing what went wrong.
No more throwing exceptions.
Much more explicit public API.

I’ve done code and architecture reviews on some big, existing codebases over the past 5-6 years. What I can tell you without reservation is that it’s much cheaper to try to do things reasonably well as you go rather than try to do a big clean up / improvement afterward

Folks seem to be weirdly optimistic about this. Anything that attracts conservative votes is going to have some horrible elements, but finally doing something to protect the Dreamers and trying to make the asylum process in the US function better seems worthwhile to me.
As Sen. Tillis rightly said, lawmakers who want to protect the border from increased asylum seeking next year have *more* of an incentive to support reform.
Republicans like Romney who says it's time to show the GOP isn't MAGA-crazy should support this:

Nothing in the world of software development sets me off more than a traditional DBA saying that developers can’t be trusted to access their database when that same DBA is not using source control or any kind of formal database migrations to track changes.

This a pretty good synopsis of everything I dislike about the .NET community.

I can't speak to their experience, but we pulled Marten out just so there was no issue about who owned it in preparation for trying to build a business model around it. Honestly, we've received much more actual support over the years from

After careful consideration, we're leaving the .NET Foundation.

“Just in case we decide to change databases” is the ultimate YAGNI violation.
In 20+ years of software development, I’ve only *once* been part of an effort to change out a backing database for a running system (RavenDb for Marten/Postgresql)
@buhakmeh
Context:
- Isolate domain from I/O implementation details
- Desire to avoid slow tests or shared fixture
- Need to swap SDKs or backing stores
Solution
- Repository Pattern
Trade Offs
- Abstraction hides platform capabilities
- Queries on repository interface hard to maintain

When you favor integration tests over unit tests in a project, it makes refactoring easier by not having much less coupling between the implementation details and the tests, but it makes refactoring slower by having slower tests. Guess there’s no free lunch.
