File under #godforsakensouth, but on a hike yesterday some insect (wasp?) stung my ankle and whatever venom it injected made my immune system go haywire. Large area of swelling around the bite, hot to the touch, heart racing, hurt like hell & it won't go away! Added itching to the mix at 3 AM.

For Part 2 of my @redmonk.com series on why modern software registries are a trust service, I look at hardened container images, where the trust-service model is furthest along. I then trace the same model in extension registries, where the Eclipse Foundation now sells an SLA on Open VSX. 2/3
