Continuations predate transducers by some ~40 years and are mostly used as a means of control flow, but yes they are very similar. Transducers are specialized to data transformatio…

Once allocators in general click, memory management in C becomes a total breeze. Combined with typed fat pointers (slices and strings), typed hashmaps and stack-trace-assertions, C…

The famous JAMA cohort study[0] of 120k people showed some 5x difference in all cause mortality and morbidity between sedentary and highly active individuals, showing effectively n…

It's important to factor in lifestyle factors here. By the time you hit 40, you've accumulated ~20 years of adult-life habits. For a lot of people, that lifestyle is very sedentary…

> very abstract things A C macro with literals that lacks referential transparency: #define MULTIPLY(x, y) x * y int result = MULTIPLY(2 + 3, 4); // 14 Not knowing what something m…

Agreed, I even find it surprisingly ergonomic. Thinking of data as offsets into memory is unusual coming from almost every other language, but once you grokk it it's actually quite…

I love that book so much, it helped me grokk the more lambda calculus aspect of FP more than anything. A few chapters in I belly laughed when it dawned on me that it's going to be …

Having to debug the build system to your build system is something else.

You evaulate code within your editor against the REPL, seeing the output in the same window you're writing in (perhaps in a different buffer). The cycle is: 1. Write production cod…

If you don't mind me asking, how old are you, and how did this progress? I'm in my mid thirties and am noticing some minor deterioration, but I'm writing it off to loss of sleep du…

Thank you for great articles and what seems to be a very nice Lisp! I've written so many toy Lisps over the years that I've lost count, always fun to see when they are done more se…

If you only had two tilesets, sure. This scales with square of n, so in a real game you're looking at a 4000-8000 long if-else chain. You're going to spend 100x more time maintaini…

Tiling sprites is a wonderful example of something that starts off relatively simple and then explodes into all kinds of interesting headaches. In the beginning, you're looking up …

Hey stop it with the ad hominems!

And with header only libraries (like stb) its even less than that. I primarily write C nowadays to regain sanity from doing my day job, and the fact that there is zero bit rot and …

The omission of quotations in the title triggered my Lisp-damaged brain to man the walls, only to immediately be met with Ruby and Scheme examples. False alarm.
