Whether that signals long-term holders cashing out or something more coordinated, nobody knows for certain yet.
Shifting to software security, a German-language deep dive into reproducible builds is making the rounds among developers concerned about supply chain attacks on Python software. The core idea is straightforward but powerful — if two independent parties can build identical binaries from the same source code, it becomes far harder for malicious code to sneak in undetected somewhere between the developer's laptop and your machine.
And on the wonderfully absurd end of the spectrum, a Japanese space researcher has successfully transferred a text file between two computers using a homemade magnetic core memory USB drive the size of a dinner plate. The technology itself dates back to the nineteen fifties, and the transfer was painstakingly slow, but the achievement stands as a genuine sneakernet first — proof that sometimes the most interesting engineering is done entirely for the love of it.
