The Best Programming Language For The End Of The World

Coding successful Forth reminded maine of nan lawless dystopia successful Mad Max. You make your ain rules, taxable to nan limits of nan context. You tin redefine nan IF connection if you truthful please. You tin rewrite instrumentality codification instructions for a Word. You tin moreover alteration Words during tally time. Because Words go keywords themselves successful Forth, you tin create a connection that’s optimized for a azygous purpose, packing commands that would different beryllium dozens of lines into conscionable one. “In Forth, you’re creating your ain language,” Leo Brodie, writer of nan first Forth textbook, Starting Forth, told me.

The low-level quality of Forth, while cardinal to its processing power, made programming consciousness foreign. It uses postfix, a shape of mathematical notation that renders 2 + 1 arsenic 2 1+ and which I recovered neither intuitive nor moreover really legible. And while astir languages let representation to beryllium surgery up and moved around, Forth is stack-based—meaning information is stored chronologically and managed connected a last-in/first-out basis. I kept moving into bugs, forcing myself to wantonness programming conventions I had considered universal. I recovered myself struggling to speak nan connection of nan machine.

When I emailed Dupras to inquire for help, he compared utilizing Forth to driving a stick. It’s much granular than C. Where nan second defines calling conventions, adaptable storage, and return stack management, Forth leaves it each up to nan programmer. It straight interacts pinch representation nan aforesaid measurement C does but acold outperforms C successful precision and efficiency. “People correction Forth arsenic conscionable a language,” Dupras says. “It’s a measurement to interact pinch nan computer.”

The logic Forth isn’t much celebrated is nan aforesaid logic astir of america thrust automatics. The individual computing roar of nan 1990s sparked an obsession pinch making tech fresh your thenar and making codification easier to write. Languages were abstracted to protect programmers from themselves, and location on nan way, we sewage lost. Things became bloated for nan liking of convenience and, successful Dupras’ words, started “oozing inscrutable pus astatine each corner.”

“The measurement we understand ratio is truthful skewed,” Dupras says. Forth is simply a scythe to Python’s lawnmower. “If you cipher nan number of joules per leaf of grass, you’ll find that nan personification scything is much efficient,” he says. “When you deliberation of speed, you’d spot nan lawnmower arsenic much efficient.” Forth forces you to beryllium precise and memory-efficient—to marshal your resources carefully, arsenic you would aft nan collapse. Dupras cuts his ain section pinch a scythe, obviously. “At a definite point, you tin spell arsenic accelerated arsenic a lawnmower,” he says.

I began to find my way. Rather than sending bytes into nan ether and trusting nan strategy to fig retired wherever they go, arsenic I would successful Python, I sewage utilized to being responsible for allocating and freeing memory. All I could deliberation astir was what was being stored, wherever it was being stored, and really overmuch abstraction it required. Each statement of codification abruptly bore weight. I was Immortan Joe, my laptop was my Citadel, and representation was my water.

Soon I recovered myself refining and revisiting my codification for illustration I would a run-on sentence. Instead of expecting nan instrumentality to expect my needs, I tried to deliberation for illustration nan machine, to meet it much than halfway. And because I had to deliberation twice, each nan needlessly analyzable acronyms that punctual america to beryllium concise successful different coding languages—YAGNI (you aren’t gonna request it), KISS (keep it simple, stupid), DRY (don’t repetition yourself)—were rendered obsolete.
