5 questions in Technology Standards.

  1. Technology Standards advanced

Organisations that had standardised on one logging library across hundreds of services found the following week expensive in a specific way. What failed, which design decision made it possible, and what is the general lesson about standards?

  3. Technology Standards advanced

    Salesforce's multi-tenant design - described in its 2009 SIGMOD paper - stores customer-specific structures as metadata over shared tables rather than giving each tenant its own schema. What does that platform-wide constraint buy the vendor and what does it charge its customers?

    The CA/Browser Forum's SC-081v3 ballot cuts the maximum public TLS certificate lifetime to 200 days from 15 March 2026, 100 days from 15 March 2027 and 47 days from 15 March 2029, with domain validation reuse falling to 10 days. Your estate has roughly 900 public certificates, perhaps 40% renewed by hand. Sequence the response.
