The project has been haunted by a mysterious bug since sometime February. It relates to the code that constructs the index, particularly the code that merges partial indices. In short the search engine constucts the reverse index through successive merging of smaller indices, which reduces the overall memory…
So I've been curious about what kinds of displays you can connect to the Pi-series single board computers for a while. I happened to accidentally order a few. Among others an eInk display. I ordered the PaPiRus ePaper. It ended up being dead on arrival and then out of stock so I received an Inky to replace it. Fair…

Geostationary satellites maintain their position relative to earth. This means a parabolic dish can be pointed at the satellite and receive continuous downloads.
In the two years after publishing this, I worked on refining this algorithm to power a real-time world generator, called Generate Worlds, and it lets you des...
When I start studying a vintage system, the first thing I like to do is understand how its components work together at the hardware level [1] .
I’m a connoisseur of failure. I love reading about engineering failures of all forms and, unsurprisingly, I’m particularly interested in data center faults. It’s not that I delight in engineering failures. My interest is driven by believing that the more faults we all understand, the more likely we can engineer…
The following is based upon systems of equations found in "Symmetry in Chaos, A Search for Pattern in Mathematics, Art, and Nature" (the second edition) by Michael Field and Martin Golubitsky. They ask the question whether there are aperiodic chaotic attractors that generate symmetric patterns? Can there be order…
When Microsoft 365 Copilot (M365 Copilot) was asked to summarize a specially crafted Microsoft Office document, an indirect prompt injection payload triggered the execution of arbitrary instructions to fetch sensitive tenant data, such as “recent emails” and hex encode the fetched output. M365 Copilot then generated a…

Deep learning, despite its remarkable successes, is a young field. While models called artificial neural networks have been studied for decades, much of that work seems only tenuously connected to modern results.
