Four short links: 10 September 2010
Philosophy of DevOps, Peak MHz, Transparency Satire, Naked Government
- Instrumentation and Observability (Theo Schlossnagle) — thoughtful talk (text and video available at that link) from a devops master. Many systems have critical metrics, which are diverse and specific to the business in question. For the purposes of this discussion, consider a system where advertisements are shown. We, of course, track every advertisement displayed in the system and that information is available for query. Herein the problem lies. Most systems put that information in a data store that is designed to answer marketing-oriented information: who clicked on what, what was shown where, etc. Answering the question, “How many were shown?” is possible but is not particularly efficient.
- Peak MHz (Mike Kuniavsky) — we hit the era of what I’m calling Peak MHz in about 2004. That’s the point when processor speed effectively peaked as chip manufacturers began competing along other dimensions. Which is why all the effort is going into horizontally-scalable systems like the NoSQL gadgets. (via Matt Jones)
- Transparency — the great British satires Yes, Minister and Yes, Prime Minister continue as one of the writers blogs in the persona of the elder civil servant Sir Humphrey Appleby. His take on transparency is funny because it’s true: I understand your anxiety about the new government’s fixation on what they are pleased to call ‘transparency’, but you are distressing yourself unnecessarily. It afflicts all incoming administrations. It used to be called ‘open government’, and reflects the frustrations they felt when they were in opposition and could not find out what was going on, combined with an eagerness to discover and publicise the deception, distortions and disasters of their predecessors.
- The Government Doesn’t Look Good Naked — a fine counter to the squawks of “the government’s open efforts suck!” that are building. this is exactly how to prevent innovation in government. If you want change, you have to tolerate imperfection and risk. If every program manager thinks they’ll end up on the front page of the Washington Post or get dressed down onstage at Gov 2.0, nothing will change. (via Tim McNamara)
