Nyquest NY8A051H – Or getting 60 microcontrollers for $1 (die shot)
If you was surprised to see 10-cent microcontroller – Nyquest Technology NY8A051H pushes price expectations much, much further down: It’s high volume pricing is just 1.5 cents, and it is currently the cheapest microcontroller in the world* (cheaper than Padauk, holder of previous record). I had to order whopping 20pcs as minimum order, and it […]

On the backend that could mean databases, scaling, containers, GraphQL, auth, scaling, etc. On the frontend there’s a lot of UX, styling, testing, responsiveness, races, waterfalls, async and lazy loads, parallelization, asset optimizations, etc. In between, […]

Convolutions, Fast Fourier Transform and Polynomials
You may remember from high school what a polynomial is. If so, you may also remember how to multiply two of them. But what if I told you that the method you were taught is slow as F? In this post we will connect polynomials with the Fourier Transform and convolutions, and show you how […]
Unification in Elixir
Pattern matching is a pervasive and powerful tool in Elixir. This isn’t too surprising if you know a little about the history of Elixir’s parent language, Erlang. Erlang was originally inspired by and written in Prolog, a logic programming language where pattern matching has first-class support. In Elixir, you might see an expression like this: […]
A Large-Scale Structured Database of a Century of Historical News
Abstract:In the U.S. historically, local newspapers drew their content largely from newswires like the Associated Press. Historians argue that newswires played a pivotal role in creating a national identity and shared understanding of the world, but there is no comprehensive archive of the content sent over newswires. We reconstruct such an archive by applying a […]
