Why Smart People Have Bad Ideas
April 2005 This summer, as an experiment, some friends and I are giving seed funding to a bunch of new startups. It's an experiment because we're prepared to fund younger founders than most investors would. That's why we're doing it during the summer—so even college students can participate. We know from Google and…

Reflecting on one very, very strange year at Uber
As most of you know, I left Uber in December and joined Stripe in January. I've gotten a lot of questions over the past couple of months about why I left and what my time at Uber was like. It's a strange, fascinating, and slightly horrifying story that deserves to be told while it is still fresh in

The Evolution of a Haskell Programmer (2001)
Some time later, I came across Iavor’s "jokes" page, including a funny bit called “ The Evolution of a Programmer ” in which the traditional imperative "Hello, world" program is developed through several variations, from simple beginnings to a ridiculously complex extreme. A moment’s thought turned up the factorial…

Nothing is Cheaper than Proof of Work
I previously wrote a post on proof of work (PoW) and mining . The first half generated great interest but (apparently) failed to be universally persuasive. For example, CCRG (Ethereum’s multi-million dollar funded “research” organization) consists almost entirely of academics theorizing about proof of stake (PoS) .

Zig cc: A drop-in replacement for GCC/Clang
If you have heard of Zig before, you may know it as a promising new programming language which is ambitiously trying to overthrow C as the de-facto systems language. But did you know that it also can straight up compile C code?

Why Chinese Is So Damn Hard (1992)
The first question any thoughtful person might ask when reading the title of this essay is, "Hard for whom?" A reasonable question. After all, Chinese people seem to learn it just fine. When little Chinese kids go through the "terrible twos", it's Chinese they use to drive their parents crazy, and in a few years the…

QBE is a compiler backend that aims to provide 70% of the performance of industrial optimizing compilers in 10% of the code. QBE fosters language innovation by offering a compact user-friendly and performant backend. The size limit constrains QBE to focus on the essential and prevents embarking on a never-ending path…

It's probably time to stop recommending Clean Code (2020)
It may not be possible for us to ever reach empirical definitions of "good code" or "clean code", which means that any one person's opinions about another person's opinions about "clean code" are necessarily highly subjective. I cannot review Robert C. Martin's 2008 book Clean Co...
