For most of Java’s history, a sophisticated exploit required a sophisticated attacker. But, in this era of AI, Anthropic’s Claude Mythos demonstrates that AI can autonomously uncover previously unknown vulnerabilities and generate working exploit paths at scale — without human expertise. What once required deep, specialized expertise can now be accomplished with little more than … The post appeared first on . Read more ›
> But my students weren’t as happy as I was - they wanted to build something genuinely useful, and they were really disappointed that our “product” had strong architectural limits and couldn’t outperform titans like nginx and haproxy. Read more ›
What this is Shared-memory threads for JavaScriptCore. new Thread(fn) runs fn on another thread, in the same heap, with the same objects. No structured clone, no message passing, no SharedArrayBuff... Read more ›

I built the same in-memory cache six ways with the Go standard library and benchmarked them across read/write mixes and core counts. Lock striping wins by up to 8×, sync.RWMutex turns out to be a trap, and one design gets slower the more cores you add. Read more ›
Every production outage traced back to a kernel driver shares the same origin: the error path was never tested. Read more ›

ZFS and Ceph are both powerful open-source storage technologies, but they address fundamentally different challenges. This article explores the trade-offs between distributed storage and standalone storage architectures, helping infrastructure teams determine when Ceph’s scalability is necessary and when ZFS offers a simpler, faster, and cost-effective solution.

Prism: An Impure Functional Language With Typed Effects This is going to be a very nerdy post so bear with me. Here is a function. Read it the way you would read any other function, and then tell me its type. fn fib(n) = var a := 0 var b := 1 repeat(n) fn let t = a + b a := b b := t a That is a mutable loop. There is a var, there is assignment, there is a temporary so the swap does not eat itself. It is, line for line, the fib you would write in Python after deciding that recursion was a youn...

Existing Decentralised Identifier (DID) methods require coordination, an agreed global order of operations, to update a DID document: blockchain-anchored methods incur fees and latency; lightweight peer methods (did:key, did:peer) offer no update mechanism; and Sidetree methods still require blockchain ordering for finality. We present did:crdt, a DID method that targets W3C DID Core and removes the need for coordination entirely: there is no le... Read more ›

Log-structured merge (LSM) trees attach an approximate-membership filter to every run and must split a fixed memory budget across them. The static optimum is known (Monkey); a large systems literature then makes the allocation adaptive, tracking shifting hotness online. We ask a prior question: when is that adaptivity worth its machinery? We give three analytical answers and validate them on synthetic sweeps, real Twitter production cache traces... Read more ›
