In battle, do not think you have to win. Think rather that you do not have to lose. Ginchin Funakoshi, founder of Shotokan karate-do We may be rarely if at all involved in battles today, but “games” are all around us, and every interaction we participate in can be thought of as a game, with its own rules, frameworks, and expectations about the participants. Such games exist in negotiations, relationships, and other interactions.....

There has been a bit of discussion over on Gemini recently regarding poorly behaved bots. I feel I need to add some perspective from the other side; as a bot operator (even though I don’t operate Gemini bots). Writing a web spider is pretty easy on paper. You have your standards, and you can test against your own servers to make sure it behaves before you let it loose. You probably don’t want to pound the server into silicon dust, so yo..

Back in the 1990s, Reduced Instruction Set Computing (RISC) architecture was widely seen as the future. UNIX workstations from Silicon Graphics and Sun Microsystems boasted powerful RISC CPUs at the time, but were prohibitively expensive and died out in the early 2000s as a result. Only the Acorn RISC Machine (ARM) architecture used in low-power devices (e.g. PDAs) survived past the early 2000s, and only because of the rise of mobil..

Exploring PL/pgSQL: Strings, arrays, recursion, and parsing JSON

Next in exploring PL/pgSQL: Implementing a Forth-like interpreter PostgreSQL comes with a builtin imperative programming language called PL/pgSQL. I used to think this language was scary because it has a bit more adornment than your usual language does. But looking deeper, it's actually reasonably pleasant to program in. In this post we'll get familiar with it by working with strings, arrays and recursive functions. We'll top it a....

Last week I was studying outside of a lecture hall where someone was teaching an introductory course on computer programming. There was a lot that I overheard that I disagreed with; this essay is an attempt to help me crystallize what exactly I disagreed with. What is programming? What is good programming? What should programming be like? How you answer depends a lot on what you value. What I value in programming has not always bee....

I’ve been getting back into C++ at Skydio, and I’ve twice lost several hours to debugging weird code behavior because of an RAII footgun in the language. A similar footgun is present in Rust, and I’ve been bitten by that too, so I figured I’d write down both. RAII classes are often used to keep resources alive or hold locks for a given scope. There observable side-effects usually occur only in the constructor and destructor.

Last updated: April 2026 Looking for a CCXT Python tutorial with real examples? In this guide, you’ll learn how to use CCXT to fetch OHLCV data, ticker information, and order book data using simple Python code. I already used the CCXT Library in my Airflow-related post here. In this post, I will discuss the library and how you can use it to pull different types of data from exchanges or trading automation. The demo can be seen here. What Yo....

TIL how to use Ansible-inventory for native ssh-connections

Actually I did not learn this today but already some years ago. Sometimes I need to connect to remote servers that have no hosts-file or dns-entry. But I don’t want to remember IP -addresses! Luckily I do have these servers defined in Ansible’s hosts-file and I could theoretically get the ip-address from there. However there’s an easier way: ansible-ssh . This is a shell-script that combines ansible-inventory with ssh to allow something..

I recently wrote about detecting driver strength in SystemVerilog . That work actually came out of solving a larger problem: How do you build a bidirectional digital wire model that includes propagation delay? Motivation The problem I had was how to model, in a digital simulation, the behavior of a “channel” (wire) for a high speed SerDes link. At the symbol rates used for modern high speed SerDes links, we start running into the physica..

A recurring problem when searching for text is identifying which parts of the text are in some sense useful. A first order solution is to just extract every word from the text, and match documents against whether they contain those words. This works really well if you don’t have a lot of documents to search through, but as the corpus of documents grows, so does the number of matches. It’s possible to bucket the words based on where they a..
