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..

GitHub Notifications icon always-on mode I tried changing the filters, waiting for a new notification to appear so that I could mark it as read, all hoping that icon would then change. But no matter what I tried in the GitHub UI, the icon was still ..

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..

Updated: 2023-01-06 About a year ago I was bitten by the PL bug. It started with reading Crafting Interpreters and discovering the wonders hidden under the hood of a compiler. I am also been a big fan of Emacs, and this started to get me interested in how its interpreter works. At the same time, I was reading the Rust book and trying to understand the concepts there. This all came to a head, and I decided to write an Emacs Lisp interpreter ..

I sit under a wild apple tree at the edge of the clearing. Like a plant, I absorb the mild October sun. At the same time, I attentively listen to the sounds of the forest. Suddenly I hear a stomping of dry leaves about twenty meters ahead of me, slightly to my right. A wolf emerges out of the thicket. He stops for a moment, glances around, then starts crossing the clearing. A few moments and another wolf appears. After a brief pause, he fol..

I’m in the middle of moving searchcode.com’s database to another server while upgrading it. This means I need to copy it somehow. It’s especially difficult in this case because the server its sitting on does not have enough disk space to do my usual mysqldump then copy the file across using SCP. I investigated splitting the database using --where clauses allowing me to get chunks of the database across, but that also means adding things l..
