  • Changing my Mind about AI, Universal Basic Income, and the Value of Data

    In this piece I’ll be talking about two particular bits of rhetoric that have found an apparently unlikely partnership in the past five years. The impending obsolescence of humanity locked eyes across the room with a utopian vision of all-powerful AI that sees to all our needs. They started a forbidden romance that has since enthralled even the most serious tech industry leaders. I myself was enthralled with the story at first, but more recently I’ve come to believe it may end in tragedy.

  • An update on Sunday’s service disruption | Google Cloud Blog

    Google posting the most inappropriately upbeat post-mortem I’ve ever read…

    In essence, the root cause of Sunday’s disruption was a configuration change that was intended for a small number of servers in a single region. The configuration was incorrectly applied to a larger number of servers across several neighboring regions, and it caused those regions to stop using more than half of their available network capacity. The network traffic to/from those regions then tried to fit into the remaining network capacity, but it did not. The network became congested, and our networking systems correctly triaged the traffic overload and dropped larger, less latency-sensitive traffic in order to preserve smaller latency-sensitive traffic flows, much as urgent packages may be couriered by bicycle through even the worst traffic jam. Google’s engineering teams detected the issue within seconds, but diagnosis and correction took far longer than our target of a few minutes. Once alerted, engineering teams quickly identified the cause of the network congestion, but the same network congestion which was creating service degradation also slowed the engineering teams’ ability to restore the correct configurations, prolonging the outage. The Google teams were keenly aware that every minute which passed represented another minute of user impact, and brought on additional help to parallelize restoration efforts.
