The First Lisp Compiler
This page examines the earliest surviving Lisp compiler, written by Timothy Hart and Michael Levin around 1961. To avoid repetition of phrases like “the compiler”, we will use the abbreviation “ HLC ” (for “Hart–Levin Compiler”) to refer to it. The HLC was introduced in M.I.T. AIM -039 and documented more fully in the…

Neural network from scratch
In this edition of Napkin Math, we’ll invoke the spirit of the Napkin Math series to establish a mental model for how a neural network works by building one from scratch. In a future issue we will do napkin math on performance, as establishing the first-principle understanding is plenty of ground to cover for today!

Why wasn't the steam engine invented earlier? Part II
As I noted in Part I, the general idea of using heat and steam for mechanical work had a long and continuous history back to ancient times. But when we talk of the breakthrough “steam engine” in the eighteenth-century sense, we don’t mean a machine that exploits steam’s expansive, or pushing force. We actually mean a…

Web3 doesn’t care about privacy
In web2, we are beholden to centralized entities that monopolize and profit off of our data. Web3 promises to release us from these shackles by enabling everyone to access data living on the blockchain. While it is certainly appealing that institutions no longer have the power to hold our data hostage, it is still…

Intel Virtualization and Apple Silicon
The transition to Apple Silicon brought about many exciting things, but one of the capabilities left behind was access to the world of Intel-based virtual machines. X86_64 just isn't a trivial architecture to emulate, and it may never be feasible to do so on Apple Silicon at a useful speed as the operating systems you…

Learning Go as a Python Developer: The Good and the Bad
I've been thinking about supplementing another language to Python for some time – mainly to cope with areas Python struggles with, or is a pain to use (which I'll go over in a minute). I had used C/C++ some years ago, but don't want to go back to them. C

EA: The Human Story (2004)
My significant other works for Electronic Arts, and I'm what you might call a disgruntled spouse. EA's bright and shiny new corporate trademark is "Challenge Everything." Where this applies is not exactly clear. Churning out one licensed football game after another doesn't sound like challenging…

Ubuntu Snap update spoiled my World Cup Final
Goodbye Ubuntu, Goodbye Snaps I missed two goals in the World Cup Finals because of this. It’s not the first time Snap has been a problem, but it’s most definitely the last straw. What happened?

An argument for a return to Web 1.0
The web was established with the best of intentions. The basic idea was that if everyone could share their thoughts and ideas with the world, the best ones would be vetted and float to the top. The bad ones would be ignored and pushed to the bottom.

Google's AI doesn't understand restaurant menus
In the glorious future, every website will be chock-full of semantic metadata. Restaurants won't have a 50MB PDF explaining the chef's vision for organic cuisine - instead, they'll have little scraps of data on the HTML page like: Copied JSON to 📋⧉ JSON"hasMenuItem":{ "@type":"MenuItem", "name":"Dodo In A Bun"…
