Yeah I’ve lost countless hours to build pipelines. Custom images/runners is the way to go. Basically docker image that runs your pipeline scripts. Then you have much more control over things.

They will be very useful in source generator scenarios.

I’ve also had good success using this package: www.nuget.org/packages/Mez...

I am more thinking about what to snapshot test and what not to snapshot test. E.g., a rule I try to follow is to not include irrelevant (to the test) data in the snapshot, as it makes it harder to validate the snapshot when it changes.

Egil Hansen @egilhansen.com · 02/05/2025

@simoncropp.bsky.social do you have a list of does and donts in snapshot testing somewhere? Examples of good patterns and anti patterns with Verify?

Yep, saw this live. Huge respect for people that dare to be vulnerable; it’s such a powerful thing.

Need a cure for that primitive obsession in #dotnet? Take a look at www.nuget.org/packages/Egi... First real attempt at a source generator library. Happy with the result. A key feature is that it’s very easy to overwrite the default generated code, just as it is with C# record classes and structs.

nuget.org

Egil.StronglyTypedPrimitives 1.9.7

A source generator for creating strongly-typed primitive types that makes it easy to avoid the primitive obsession anti pattern. Add a [StronglyTyped] attribute to a partial record struct ...

Going live with @steven-giesel.com for the first #bUnit dev session of this month. We may even get a visit from @scottsauber.com :) Join at twitch.tv/egilhansen and www.youtube.com/watch?v=jZrZ...

Actually, I think I usually do a `git clean -fdx` for a "reset the world" operation.

Egil Hansen @egilhansen.com · 06/03/2025

There is a git command that does it, just can’t remember it when I need it, so have to search the web. If your tool had a -all option that would be great 😊

Egil Hansen @egilhansen.com · 06/03/2025

Could it also have an option that does the same a clean git clone? Sometimes deleting e.g., the .vs folder helps with weirdness in vs.

Egil Hansen @egilhansen.com · 03/03/2025

By using Aspire and related client libraries you get basic telemetry out of the box (without solution specific context), so I’ll do that and then add some/few end-2-end tests for basic protection against regressions.

Egil Hansen @egilhansen.com · 01/03/2025

@captainsafia.com does (or will) #dotnet's OpenApi generator have a way to declare a custom schema transformer for type as an attribute, like we can with JsonConverter? E.g.: [OpenApiTransformer<MyIdSchemaTransformer>()] public record MyId(int Value);

110

Egil Hansen @egilhansen.com · 28/02/2025

They do, but we have something called incremental generator, that ensures a generator only runs when the code it’s targeting has changed, so that helps quite a bit. @captainsafia.com can speak to this quite a bit better than I can.

Egil Hansen @egilhansen.com · 28/02/2025

Thanks, appreciate your efforts here.

I’ve been working on a source generator last weekend and borrowed some of your snapshot test helper code from your open API generator. It would be awesome if you would post the newest version of that in a gist/blog with a bit of code comments for us source gen newbies to understand it better 😊

Ugh those build times thought. Lots of coffee breaks for you I see :)

in my case if I were to scale down my job to part time (can’t scale family time down) to spent more time maintaining and extending my OSS projects, if I want to keep the same income level. 2/2

100

Correct, at least for bUnit I’ve been lucky to get co maintainers on board and the amount of work we have to do is manageable. The problem is at the end of the day a lack of time. Full time job + full time family doesn’t leave a lot of spare time to OSS. Founding would need to be significant 1/2

100

I big one is also the feeling of responsibility, implicit promises made (in my mind at least), not wanting to change things on existing users, and potential loss of reputation, all of that weighted against expected “income”.

Rob Mensching @robmensching.com · 26/02/2025

Why not add to existing projects? Not sure I have a good answer, yet at least. Have to give the site a proper read through, make sure all implications are understood, cost/benefit analysis, etc.,

I like the way Rob phrases this, software is free, maintainers time is NOT. I’ll consider this for new projects going forward.

What language are you programming in and what are you building?

Egil Hansen @egilhansen.com · 11/02/2025

True. Even so, do you really need more than 240/280mm rad even for Intels hottest 13th gen CPUs, even under sustained loads? Or are you overclocking too?

100

Egil Hansen @egilhansen.com · 11/02/2025

But isn’t a 280mm or even 240mm enough to cool those CPUs? Check out youtube.com/@optimumtech Fair warning. It’s a rabbit hole once you get into SFX builds, but it’s very satisfying.
