The Fisher-Yates shuffle is backward
Given a list of elements, such as cards in a deck, what is the right way to shuffle the list? That is, what is the appropriate algorithm to (pseudo)randomly permute the elements in the list, so that each of the possible permutations is equally likely? This is an interesting problem, in part because it is […]

Pretty much the usual decades-old hype, with nothing even slightly different than what a similar conversation would have consisted of 20 years ago. Of historical and psychological interest, Witten explains that when the anthropic landscape nonsense arrived, […]
Proving Bounds for the Randomized MaxCut Approximation Algorithm in Lean4
../randomized-maxcut Published on: 2025-12-19 For a given graph G = (V, E), a cut C is a set of edges such that there is a partition V = (A, B) where all edges e ∈ C have one vertex in A and the other in B. MaxCut is a very famous combinatorial optimization problem wherein […]

What Does a Database for SSDs Look Like?
Maybe not what you think. Over on X, Ben Dicken asked: What does a relational database designed specifically for local SSDs look like? Postgres, MySQL, SQLite and many others were invented in the 90s and 00s, the era of spinning disks. A local NVMe SSD has ~1000x improvement in both throughput and latency. Design decisions […]
