Table of Contents Discussion and Outlook 🧸 It’s Casey. Casey Cuddle. I am very happy to announce the first stable release of kcctl , a modern and intuitive command line client for Apache Kafka Connect ! Forget about having to memorize and type the right REST API paths and curl flags; with kcctl, managing your Kafka connectors is done via concise and logically structured commands, modeled after the semantics of the ..

Let’s say we have a distribution $X$ that is given by its $s$-quantile values: $$ q_{X_1} = Q_X(p_1),\; q_{X_2} = Q_X(p_2),\; \ldots,\; q_{X_{s-1}} = Q_X(p_{s-1}) $$ where $Q_X$ is the quantile function of $X$, $p_j = j / s$. We also have a sample $y = \{y_1, y_2, \ldots, y_n \}$ that is given by its $s$-quantile estimations: $$ q_{y_1} = Q_y(p_1),\; q_{y_2} = Q_y(p_2),\; \ldots,\; q_{y_{s-1}} = Q_y(p_{s-1}), $$ where $Q_y$ is the quant..

Bar chart of price convergence per day in 2021 for CWE region (click to enlarge) What is price convergence? The electricity market in Europe is split into so-called bidding zones. The rule is that within these zones you can trade without transport restrictions, as if the entire grid there is one big conducting plate. This also means that for the day ahead marketi, there is one price per hour per bidding zone. If neighbouring bidding zon..

For a while I’ve been wondering what it would be like to use arenas in Rust. In C and C++ I have been turning to arenas more and more as a fast alternative to heap allocation. If you have a bunch of objects that share a common lifetime, arenas offer cheaper allocation and much cheaper deallocation than the heap. The more I use this pattern, the more it feels downright wasteful to use heap allocation when an arena would do. I’ve been....

I’ve started playing around with TypeScript for the first time over the last couple of weeks and it is excellent. I’ve made a few hobby JS games in the past as you can see from the games page. JavaScript was always fun for me, but after years of statically typed languages I have grown to prefer them.

Lately I’ve been experimenting with Rust, and I want to report some of what I’ve learned about thread-safety. I am an enthusiastic dabbler in Rust: I spend most of my time in C and C++, but I’m always looking for an excuse to learn more about Rust’s approach to the techniques I use every day in C and C++. When studying Rust’s threading model, I came to see some correspondence between C++ and Rust terminology that I had not seen published....

This is a tale of finding fractals in an unexpected place and why the appearance makes sense in hindsight. I was looking for patterns in valid board game configurations, specifically the middle contesting row in the Game of Ur. In the game, there are eight slots either of the two players may occupy, but a slot may only be occupied by at most one player. I represented the available slots as two bit strings, with each bit representing a sin....

Building — and adopting — a component library in the context of a vibrant business is no easy feat. Here are a few things we’ve learned. At a small startup, the timing is never quite right to start a component library. Extremely quick iteration is not usually associated with putting together a standardized set of components and conventions to use across your app, as your components and conventions change all the time in the frenzy of findi....
