Rx Part 7 – Hot and Cold Observables
STOP THE PRESS! This series has now been superseded by the online book www.IntroToRx.com. The new site/book offers far better explanations, samples and depth of content. I hope you enjoy! In this p…
This is really nice, but I think your impl have significant semantic differences to Rx.NET wrt hot vs cold observables. In Rx every observer has their own separate subscription chain while it seems to me that in your impl. they share the same upstream subscription? leecampbell.com/2010/08/19/r...

The blog is written in jupytext, so it's all Python code with comments translated to Markdown. All the code examples are also linted using ruff, and type checked using pyright. Even the example errors are checked for the correct error 🥰 #python #ruff #pyright

Very happy to see this new alpha version of Fable being released 🥰 The Python target is getting a well-deserved upgrade.

Todays summary after a 12-hour session. Most Python developers never touch meta-classes. Most F# developers never think about Python descriptors, at least not at the class attribute level. Doing both simultaneously while solving circular dependency problems in a compiler context! 😅 Time to sleep 😴

small PR, might be you do not need it, but now Feliz.ViewEngine also has a bare bones support for representing events in its DSL, for most scenarios might not be what you need i was experimenting with Vue bindings, thanks @dbrattli.bsky.social for helping out! 🦔 github.com/dbrattli/Fel...

The Rust implementation gives us control to handle .NET edge cases. Still early days with great opportunities for perf improvements and code that type checks correctly. That's the dream! 🐍🦔🦀✨ #fsharp #python #fable #rust #pyo3

The big win? No more confusion because our Int32 is actually Python's arbitrary-precision int. We're making Python behave like .NET - proper integer overflow, real array semantics. Surprisingly hard to make Python integers act like actual Int32s, but worth it 🐍🦔🦀✨

Working on something that's getting me excited 🥰 For Fable 5 Python target we're rebuilding Fable Library in Rust to get proper .NET semantics when transpiling F# to Python. As a Python dev who fell hard for F#'s type system, this scratches an itch 🐍🦔🦀✨

Task estimation: Conquering Hofstadter's Law
How to turn your time estimates into reliable predictions — and communicate them.
"That means the developer’s estimate, while far from perfect, is also far from meaningless: it’s the scale parameter of some distribution."
