Sometime last week, I noticed that I had a missed call from an unknown number. Curious to know who the caller was, I called back. To my pleasant surprise it was one of my ex-senior colleagues, Sarvesh. It had been a long time since we'd spoken to each other. After a quick general chat, the conversation turned to technology.
We recalled the old days of working on PCI Express; those debates we would have over Advisory non fatal error reporting in the Advanced Error Reporting (AER )1.1 part of the PCI Express specification. The AER was a challenge in terms of specification interpretation. But, Sarvesh was adept at it. I learnt a lot from him. A perspective that he provided which I still cherish is his question: What will a particular inference in case of ambiguities translate to, in real world? Often this question helped us discover “why things are the way they are” and resolve the ambiguities.
