It is by now well known that YAML has a Norway problem, where the country code NO is interpreted as boolean false. But did you know about YAML's related implicit conversion of numbers footgun? Take this list of hex strings: [1810, 1910, 1a10, 1b10]. Parse it with a YAML parser, e.g. Clojure's clj-yaml1's parse-strin...

Whenever I get into a new technology (A new database feature, a fancy distributed queue, an orchestration system), I try to build myself a mental model of how it works.Today, we’ll build a mental model for Full Text Search engines (along with some code in Rust), as done in database systems such as Elasticsearch, Pos...

Lisp programs don't have parentheses — they are made of nested linked lists. The parentheses only exist in the printed representation — the ASCII serialization — of a Lisp program. They tell the Lisp reader where the nested lists begin and end. Parenthesis are the contour lines in the topographic map of your Lisp pr...

This post is a brief ‘warm up’ to a short series of posts on interesting aspects of Nvidia’s and competitors histories and technology. We’ll next look at Nvidia’s PTX ‘assembly language’ (actually an intermediate representation) that has been making headlines due to its use by DeepSeek. I’ll argue that PTX is part o...

The Y combinator is a central concept in lambda calculus, which is the formal foundation of functional languages. Y allows one to define recursive functions without using self-referential definitions. Most articles I’ve seen dedicated to explaining the Y combinator start by showing you the Y combinator, which in its...

There are a lot of guides about how to use async Rust from a "user's perspective", but I think it's also worth understanding how it works, what those async blocks actually mean. Why you get all those weird pinning errors. This is the first post in a series where we're going to slowly build our way up to reinventing ...

Let's talk about why Snapshot Isolation is not enough for a general purpose concurrency control. Snapshot Isolation has been adapted by several major database vendors however, it is rarely used outside of Database Management Systems… Why is that? According to the wikipedia, Snapshot Isolation (SI) is a guarantee tha...

Visualizing a Million Time Series with the Density Line Chart

Abstract: Data analysts often need to work with multiple series of data—conventionally shown as line charts—at once. Few visual representations allow analysts to view many lines simultaneously without becoming overwhelming or cluttered. In this paper, we introduce the DenseLines technique to calculate a discrete density representation of time series. DenseLines normalizes time series by the arc length to compute accurate densities. The derived density...

The OpenBSD kernel has a set of functions to help detect memory corruption, the poison subroutines. The memory management code uses these functions, but they themselves have a very simple interface, no complicated types or data structures, meaning they’re easy to replace. What if we rewrite the memory corruption det...

After spending hours wading through sparse documentation when evaluating new tech, I’m wondering what promotional sites you all actually find useful when making tech decisions. Beyond the official docs, what vendor/project sites have genuinely helped you understand a technology/library/component/app’s capabilities and tradeoffs? I’m looking for examples where marketing sites actually delivered a a clear message - whether through interactive demos, architecture diagrams, practical comparisons,...
