Hi everyone, I have been reading about Distributional Maximum a Posteriori Policy Optimization (DMPO), especially in the context of the DeepMind bipedal robot soccer paper, and I am trying to understand when one would practically prefer it over SAC. My current understanding is: SAC is a strong off-policy continuous-control baseline. It directly optimizes the actor using an entropy-regularized objective. It is widely implemented, easier to find baselines for, and generally very strong in simulation. On the other hand, […]

At RSA Conference this year there were 650+ security vendors. All of them were selling security products. Almost none of them were selling security practices. This distinction sounds academic. It isn’t. A security product gives you a tool and a dashboard. A security practice gives you a discipline that gets embedded into how your engineers work every day. The security industry has spent 30 years optimising for selling products. The result: organisations with extraordinary tooling and catastrophic outcomes. […]

grep finds things. cut and tr shape what you do with them. Most practitioners pick these up by accident — copy a one-liner from somewhere, it works, move on. But understanding what cut and tr actually do changes how you build pipelines. You stop reaching for awk when cut is enough. You stop writing substitution logic by hand when tr handles it in seconds. This article covers both tools from the ground up — what they do, every […]

AI does not make security impossible. It makes slow, static and periodic security obsolete. This is a long-form strategy article about how enterprise security changes when AI compresses the time between vulnerability discovery, exploit development, attack execution, remediation and validation. The core idea is simple: Post-AI Security starts by shrinking the time between detection, decision, remediation and validation. The starting point can be ugly and simple: better inventory, existing scanners, available live patching, ownership, and common sense in […]
