We’ve discussed SIMD and vectorization extensively on this blog, and it was only a matter of time before SIMD (or vector) functions came up. In this post, we explore what SIMD functions are, when they are useful, and how to declare and use them effectively. A SIMD function is a function that processes more than… Read
You know when you're really jet lagged and really tired and the cogs in your head are just moving that little bit too slow? That's me right now, and the penny has just dropped that a Mailchimp phish has grabbed my credentials, logged into my account and exported
DHH's politics are not normal. Maybe they used to be, I don't know, but as of right now the dude is way outside of what most people would consider moral or acceptable.
Cryptographic schemes are based on the computational difficulty of solving some ‘hard’ problem. For example, RSA (specifically, RSA-2048) is based on the difficulty of a problem like this:
A year ago I decided to help build a service business for my mom because I wanted to learn about marketing and business. One of the largest blindspots engineers have is around sales and marketing. I was determined to not fall into this trap, but marketing seemed like a skill I couldn’t just learn by […]

And implications for RLVR progress
My life is not a math Olympiad
I built a simple web crawler using good old platform threads. It was just a multithreaded crawler, nothing fancy. But then, curiosity…
A no-BS guide for new startups, new products, new GTM approaches, and new features
Guidelines for creating a living personal Web site.
Dithering is still a surprisingly applicable technique, not just for practical reasons (such as preparing a full-color image for output on a non-color printer), but for artistic reasons as well. Dithering also has applications in web design, where it is a useful technique for reducing images with high color counts to…
Success! There is machine learning happening on my Apple ][+.
ImapGoose is a small program to keep local mailboxes in sync with an IMAP server. The wording “keep […] in sync” implies that it does so continuously, rather than a one-time sync. ImapGoose is designed as a daemon, monitoring both the IMAP server and the local filesystem, and immediately synchronising changes. When…
Optimizing compilers like to keep track of each IR instruction’s effects. An instruction’s effects vary wildly from having no effects at all, to writing a specific variable, to completely unknown (writing all state).
Turning LLMs into coding experts and how to take advantage of them.
There's a new web search in town! I spent the start of 2024 kicking the tires on Kagi's paid search and their Orion web browser.
A balanced take on the printf vs debugger debate: why there is no single right answer, and how to choose the right debugging approach for the situation at hand.

Introduction Quadratic funding has received a lot of attention recently as a mechanism for funding public goods. The Gitcoin grants program alone has distributed over $59M through QF funding rounds as of January 20241.\nQF is appealing because it is theoretically optimal under certain assumptions2. The problem is that…
Its market cap hit $777 million and Bill Gates' net worth reached $350 million
The agentic loop—generate, assess, improve—seems like a natural fit for iterating on pelicans on bicycles.
I like to answer this frequent question by way of an example. An example of two companies. It goes something like this:
Planet 9 might be our Ultima Thule . Hell would certainly be freezing over at 700 AU. Whether this tentative observation is Planet 9 or not, it is still an interesting observation and an example, I think, of proof that AIs will not do all our science for us. (At least not LLMs).

A now-deleted report by HonestAGI on GitHub showed a high number of similarities between Huawei’s Pangu and Qwen 2.5.
