Yeah not a prob for me either, I love having all that subscribed "generally interested, but never pressing-need-to-know-right-now" simply pile up offline in my reader. Then once in a while I'm stuck somewhere offline with no

A little boilerplate hasn't killed anyone. If you're talking about "100s of different Enterprise Business Objects (TM) structs", something is probably off in the overall program design and/or code-gen should probabl

On the whole I agree that I prefer Go's explicit error returns over other languages implicit "alt-return paradigm" aka exceptions. But you're really well advised here to run a couple of linters occasionally that inform a

From what I can tell VCL was simply the "pioneer" of what afterwards became "the bog standard approach" from VB to WinForms, Qt, Gtk etcpp. Essentially an OOP class hierarchy with everything inheriting a root "Compo

For developers, information breadth and quality was excellent when I first onlined in '98, and has improved by leaps and bounds year by year. For other stuff, I agree with that OP article, that was a uniquely rich caleidoscope that got

Agree, I always enjoyed hacking on shaders. And checking out other's shaders (and further tweaking them) is also inspiring educational and most gratifying. ShaderToy is a great site for that, but there's many more "shader com

"Officially" isn't really a thing here, I feel. I mean the `purs` (formerly `psc`) compiler just gets given a list of .purs files from your build setup (pulp, custom make files, a little custom program, whatever) and recompi

Some truth to this possibly. This sort of concern would be addressed by the library ecosystem rather than "the language", which might not be for everyone. I mean PS arrays/records map to JS arrays/objects as far as passi

That's the whole point of ShaderToy AFAIK: no geometry, all pixel magic. Whatever you see on there is entirely frag-shaders. If it looks like geometry, it's still just funky fancy formulas in image space
