We will soon be moving forward with some long-planned changes to Rx.NET packaging. This is the last chance to comment github.com/dotnet/reactiv…

@headinthebox There was plenty of conceptual and practical guidance around all things IObservable<T> back when Rx.NET was released. The join patterns...well if there was any, I missed it despite being an Rx enthusiast.

@headinthebox I think one issue with the Rx implementation is that there wasn't a lot of good explanatory material (or if there was, I never found it). I remember stumbling across these in the library and wondering what they were for (despite having watched and read lots of Rx content).

2024.ecoop.org/details/ecoop-… ... Join patterns provide a promising approach to the development of concurrent and distributed message-passing applications ... I am completely flabbergasted why join patterns remain the eternal promising approach for coordination. Tried several times to push them into the mainstream first with Visual Basic (researchgate.net/publication/22…) and then with Rx (learn.microsoft.com/en-us/previous…). Keeping my fingers crossed that @philippkhaller will succeed.

@Hr_Panahi Hi! Glad you're enjoying the book. Yes, my apologies, this is a mistake in the example label (and one I have already corrected in the C# 12.0 edition, which will be coming out in a few months). The surrounding text does correctly state that this is contravariance in action.

Hey @idg10 , I've been enjoying your book 'Programming C# 10.0', but I noticed a small typo. In Chapter 9, this example title 'Delegate Covariance' seems like it should actually be 'Delegate Contravariance'. Can you confirm? Thanks!

Since taking over development of Rx .NET, I spent a big chunk of last year working on this: endjin.com/blog/2024/01/i…

@Dave_DotNet The fan-out-then-back-in approach that this operator uses is one I've often found useful in Rx, so the ability to visualize it automatically would be amazing.

@Dave_DotNet I show how to build a Quiescent operator, and to understand how it works, it's helpful to visualize all the inner observables it creates (which I've done by drawing them manually in Illustrator).

We just released a new version of Rx.NET! endjin.com/blog/2023/05/r…

@cecilphillip @HowardvRooijen Hi! My twitter presence is a bit sporadic these days - sorry! But Rodney just DMed me, which successfully got my attention.

@HowardvRooijen @idg10 👋🏾 Hi Ian

System.Reactive v6 preview 9 is available on NuGet: nuget.org/packages/Syste… Full changelog available here: github.com/dotnet/reactiv… Thanks for all the hard work @idg10 👏👏👏

@laurentkempe @Lucas_Trz @HowardvRooijen ...but the fact that they went for that really specific version and not net5.0-windows (which I believe actually means net5.0-windows7) suggests there must have been something driving that specific decision. I'd want to understand this choice before reversing it.

@laurentkempe @Lucas_Trz @HowardvRooijen I have no idea why Rx originally opted for 10.0.19041. The significance of it is that it makes Windows API surface area newly introduced in that version of the SDK available to the library, but I don't know what it was about that particular version that made them choose it.

@antony @WilliamRMPrice There are a few places where it happens to work, but plenty where it doesn't. E.g., travel on the Northern Line out to High Barnet, and you'll see this rule doesn't work.

@blackhawksq @endjin @edfreeman_ I don't see a DM from you. Is it possible you DMed @endjn or @edfreeman_ instead of me?

Sound advice from @endjin’s @edfreeman_ at today’s Modern Data DevOps workshop at VS Live in Orlando.

@ploeh @ladeak87 Speaking of Twitter not being the place for these things, I've written a more considered explanation of my position here: endjin.com/blog/2022/11/i…

@ladeak87 I have multiple objections to such assertions, but I don't think Twitter is a good medium to discuss implications. It could easily look like an attack on the messenger, which wouldn't be my intent.

Git squash is destructive. Why burn a bridge behind you? You can always squash locally if you ever need to, but you can't reconstruct the history you destroyed. A comment: #comment-3107665" target="_blank" rel="nofollow noopener">stackoverflow.blog/2022/04/06/use…

Always a delight to witness an energetic speaker who’s knowledgable and super excited to share what they know. The UK accent doesn’t hurt :) Ian Griffiths talks reaqtor at VS Live Orlando @idg10 @VSLive

At @endjin, we've found C#'s low-allocation features can have a huge performance impact. Here's one example of where we've used it: endjin.com/blog/2022/10/h…
