@rygorous @aeva for what is worth, your blog and your infodumps have been part of a transformative experience for me. I was ready to give up after more than a decade spent in random best practices and oop stuff and it felt all so empty. Then I found out there are still people that care about the things I like, and they even like to share! Sometimes all you need is exposition and I really needed to be exposed to your kind of infodumps and blog posts. Thank you

@aeva i vote for map or remap for both the forward and inverse operations, as in map(x, domain_low, domain_high, codomain_low, codomain_high), with maybe shorthands for map_to_01 and map_from_01

@SonnyBonds @nothings @aras yeah, me too! and the fact that it is even an option to consider speaks volumes about <gestures widely> everything!

@eniko sometimes the old techniques are the appropriate ones. too bad juniors are actively told that dealing with bits and low level concepts is not relevant and 'premature optimizaiton'. one of my clients has engineers with a terrible fear of exoteric concepts such as 'bit masks'... such is life!

@eniko some years ago i helped with a project in a low energy context: once in a while a sensor would trigger an interrupt, waking up the device. not all the wake ups needed an action, to figure it out you would need to do a bunch of non linear calculations and react accordingly. using floats pushed the device over the maximum energy consumption, as it was powered with non rechargeable caps. fixed point math with an iterative solver outperformed fp, doubling the expected life of the device.

@eniko i want to write a small library/toy language of sort to help me deal with fixed points math, mainly for embedded projects. the main problem i found is when you also need to account for the non fractional bits to avoid overflowing the integer type, and sometimes adjusting things have a ripple effect that is a pain to deal with. some side verification and a bit of code generation would really help. too bad that lately i am constantly overworked to allocate time for that tho!

@mcc Happy birthday!

@0xabad1dea and the ringtone part ends with an harmonic A, so it’s even anticlimactic on the last note!
