Or… Notes on the IPMI Protocol Security Model. I wrote in Sold Down the River about the curious aspects of channels and authentication and users and all that stuff.

npm is the defacto package manager for the node.js javascript network programming environment thingee. The folks who make npm have taken a security leap: npm no longer supports its self-signed certificates Ah, they build the bastions of light and goodness, protecting us from the sins of the masses by standing tall.

I love the idea of calculating value based on… not much. I don’t know how accurate it is, but I can say that when run on systems (just before Elemental spontaneously combusted) it produced some really cool […]

I should have […]
