ok, so, you know how the standards (C/POSIX) allow malloc(0) to return NULL?
i went to refresh my memory after a discussion of a security issue today and as best as i can tell, no commonly used OS has ever had malloc(0) return NULL, including historical ones¹. windows, glibc, musl, BSDs, all return a non-NULL pointer to some object

Zama becomes 1st fully homomorphic encryption unicorn with $57M raise
French open source cryptography company Zama today announced a $57 million Series B funding round co-led by Blockchange Ventures and Pantera Capital, bringing Zama’s total funding to over $150 million, and its valuation to north of a billion USD.  Founded by Dr Pascal Paillier and Dr Rand Hindi, the company is building state-of-the-art Fully Homomorphic Encryption (FHE) solutions for blockchain. Fully homomorphic encryption (FHE) allows computations to be performed on encrypted data without…

Spaces of homomorphisms, formality and Hochschild homology
Let $G$ be a discrete group. The topological category of finite dimensional unitary representations of $G$ is symmetric monoidal under direct sum and has an associated $\mathbb{E}_\infty$-space $\mathcal{K}^{\mathrm{def}}(G)$. We show that if $G$ and $A$ are finitely generated groups and $A$ is abelian, then $\mathcal{K}^{\mathrm{def}}(G\times A)\simeq \mathcal{K}^{\mathrm{def}}(G)\otimes \widehat{A}$ as $\mathbb{E}_\infty$-spaces, where $\widehat{A}$ is the Pontryagin dual of $A$. We deduce a …
