#virtual #threads #rxjava #whoes 1) Time for a few new Streamable<T> operators! 2) Doesn't work. 3) No problem, debug virtual threads. 4) Doesn't work in Eclipse 2026.6, "packet timed out" on single step. LMAO, switch to virtual threads they said! It will be easy to debug they said! I have to use the old fashioned and reliable SingleThreadedExecutorService for the debug! Deadlocks. Do you know what doesn't deadlock? Non-blocking code like the rest of RxJava!

#java #rxjava #language Turns out, we already have a clumsy but working way for a few language features I unkindly requested: - auto Varhandles ~ AtomicXXX classes - async ~ create() with an emitter.emit() call for yield returns - await ~ await(CompletionStage [, DisposableContainer]) Universal Turing Complete von Neuman computers rule! Given a 10 foot pile of sh|t, a programmer can build an 11 foot high ladder and step over it. ~ Cory Doctorow, Ensh|ttification 🫡🥚✝️

Wow. Interesting thesis. https://t.co/PtLZ7J5YNu If you can, please redo it with #RxJava 4's Schedulers.virtual() instead of wasting 1,000+ cached threads on blocking IO at once. Also it is not explicitly mentioned by the document, but Structured Concurrency won't save you much. Coordination is one of the hardest part of async programming and you'll sweat blood getting it to work for non-trivial and/or multi-valued use cases. I know, because I did sweat. Worry not. We'll fix that with Streamable<T> / Streamer<T> just fine. 😏Stay tuned!

Now that #RxJava 4 is brewing, expect job listings requiring 5 years of experience with it. So if you did Rx 4 already in 2021, you'll be golden. 😆

#java #idea #rxjava Here is my list of Java language enhancements that would make our RxJava life much much easier: - Extension methods. - Generators á la C#, yield return X and yield return async X. - Syntactic sugar async/await on top of Virtual Threads - Syntactic sugar atomics, atomic_read(x), atomic_cmpxchg(x), etc. - Obtaining names via nameof(method|param|variable) at compile time. These all seem to be doable, and anomalies worked around just fine. Please do it. Please. 🥺🙏

#rxjava #proposal I've just posted a new hybrid reactive-virtual type Streamable<T> and its provider Streamer<T>. It is a multi-valued sequence that complements the executor.submit() type one-shot calls with Virtual Threads. It is going to be modelled after C#'s IAsyncEnumerable<T> type. Virtual threads make it very convenient to block on join() calls. However, I'd rather have syntactic sugar support in Java: await someCompletionStage;. Any state machine builder for yield return and yield return async would be also welcome. https://t.co/SM2U7nHkby

#scifi #rxjava I've been thinking about why 🖖 Star Trek Discovery was interesting and odd at the same time. Michael's hyperactive inference made it unstable-to-mundane to my eyes. However, when she was contrasted with a great captain such as Lorca, Pike and Rayner, the duo shined. Add in a McCoy-esque unity of Booker, Tilly, Stamets, Saru, et all, and now we have a stable 3-body system. Season 5 was good, but not perfect. I think the issue was that Rayner became number-1. He should have been the captain of the situation, making Michael his number-1 instead. The show needed a seasoned leader who can filter through Michael's and the others' ideas through his experienced lense and make the decision. Not Michael. Rayner not knowing or being capable of all the inference was not a bug. It was a feature. 🤔 Which brings us to RxJava. I have many ideas and resolves to make it great again. But I'm too technical, driven, loopy. The best years were when Ben Christensen was at the helm. He is an industry veteran who could filter through the ideas and resolves in a reliable, safe and measured way. Our McCoy was probably the engaged community members who also provided contrast and feedback to the library. I miss those days. So what does this mean with regards to RxJava 4? Technically doable, all doable. But we'd end up with a huge library if we do the full reactive triad / tetrahedron. We need a filter. I need a co-operator, maybe even two. To be clear, I'm not stepping down or release my admin powers. I invite qualified and established people like Ben & others to show up and get involved. We can go slow, no need to do everything within 10 days. I can, but won't. But I could 😉 🙏 for listening.

Harnessing the power of parallelization with #RxJava and #OpenCV to efficiently resize large number of images using batch-parallelization! Additionally, you can similarly use Deeplearning4J for resizing with interpolation methods like Lanczos and Bicubic. #Java

I know many have moved to #kotlin coroutines, but I also know some of you are still diving deep into #rxjava—even after 5 years of experience with it
