The coverage that followed was predictable in its breathlessness: AI has developed a mental workspace, LLMs might be thinking in a way we can now readThu, 09 Jul 2026 00:00:00 GMTAIInterpretabilityTechnologyPhilosophyhttps://jamielittle.uk/notes/graph-fourier-transform/https://jamielittle.uk/notes/graph-fourier-transform/The ordinary Fourier transform decomposes a signal into frequencies, and "frequency" makes intuitive sense when your signal lives on a line or a circle: it's how fast a sine wave oscillates as you walk along that line. But plenty of data doesn't live on a line.

A spanning tree is a subset of edges that connects every vertex with no cycles, the minimum skeleton that holds the graph together. For a small graph you can just draw them all out.

You get `0.30000000000000004`. This is not a Python bug, not a CPU bug, and not something that better software engineering would fix. It is a direct consequence of what real numbers are, and no amount of additional hardware could ever fulMon, 29 Jun 2026 00:00:00 GMTComputer ScienceMathematicsTechnologyhttps://jamielittle.uk/notes/fable-ban-and-ai-safety/https://jamielittle.uk/notes/fable-ban-and-ai-safety/On 12 June 2026, the US government issued an export-control directive ordering Anthropic to suspend global access to its two most capable models, Claude Fable 5 and Claude Mythos 5. Within hours, both were offline for virtually every user on the planet, not because Anthropic had Sat, 13 Jun 2026 00:00:00 GMTAIPolicyTechnologyhttps://jamielittle.uk/notes/raft-consensus/https://jamielittle.uk/notes/raft-consensus/Distributed systems have a fundamental problem: how do you get a collection of machines to agree on something when any of them might crash, messages might be delayed, and you can't tell the difference between a slow node and a dead one? This is the consensus problem, and getting Wed, 10 Jun 2026 00:00:00 GMTRaftDistributed Systems
