Designing and assembling my first PCB

https://vilkeliskis.com/b/2026/i/pcb_breadboard_components.jpg
About a couple months ago I purchased an Arduino Nano ESP32 dev board. I had this sudden itch and I wanted to play around with hardware. I don't really have much experience in this space, besides working on firmware for an IoT company over a decade ago, but I've written tons of software over the years. I was very surprised how quickly I was able to get the built-in LEDs to blink with ...

Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k

https://systima.ai/images/claude-code-vs-opencode-banner.png
Claude Code incurs ~33,000-token overhead per request (vs OpenCode’s ~7,000) due to extensive system prompts, tools, and mid-session rewrites, while OpenCode’s stable, cached prefixes minimize costs. Subagent workflows amplify Claude Code’s token usage 54x vs OpenCode’s lean design, with configuration files and MCP servers further inflating baseline costs.

Architecture Description Languages [pdf]

Abstract—Software architectures shift the focus of developers from lines-of-code to coarser-grained architectural elements and their overall interconnection structure. Architecture description languages (ADLs) have been proposed as modeling notations to support architecture-based development. There is, however, little consensus in the research community on what is an ADL, what aspects of an ...

A Speed Limit for Computers

The home and personal computing revolutions of the 70's, 80's, and 90's put the power of computing in the hands of the masses. For those of us that grew up with these machines, it can be hard to reconcile the computer culture of our youth with the industry we find ourselves in today. But at some point, a threshold was crossed and increasing computing power no longer translated to ...

Why write code in 2026

Profiling the "Abundance" housing bottleneck with real data

https://i.snap.as/wjoTv1yV.png
My book club is reading Abundance by Ezra Klein and Derek Thompson this month. The core idea fits on a napkin, so before the meeting I decided to actually check it against real data. Here's what I found, and where it fell apart. Housing, clean energy, cures for disease. The inputs to all three haven't really moved. Money's there. Technology got cheaper, not more expensive. Roughly ...
