Amazon DynamoDB Accelerator (DAX)
Amazon DynamoDB Accelerator (DAX) is a fully managed, highly available, in-memory cache for DynamoDB that delivers up to a 10x performance improvement – from milliseconds to microseconds – even at millions of requests per second. DAX does all the heavy lifting required to add in-memory acceleration to your DynamoDB tables, without requiring developers to manage cache invalidation, data population, or cluster management. No latency percentile figures, unfortunately. Also still in preview.

I Just Love This Juicero Story So Much
When we signed up to pump money into this juice company, it was because we thought drinking the juice would be a lot harder and more expensive. That was the selling point, because Silicon Valley is a stupid libertarian dystopia where investor-class vampires are the consumers and a regular person’s money is what they go shopping for. Easily opened bags of juice do not give these awful nightmare trash parasites a good bargain on the disposable income of credulous wellness-fad suckers; therefore easily opened bags of juice are a worse investment than bags of juice that are harder to open.

Zeynep Tufekci: Machine intelligence makes human morals more important | TED Talk | TED.com
Machine intelligence is here, and we’re already using it to make subjective decisions. But the complex way AI grows and improves makes it hard to understand and even harder to control. In this cautionary talk, techno-sociologist Zeynep Tufekci explains how intelligent machines can fail in ways that don’t fit human error patterns — and in ways we won’t expect or be prepared for. “We cannot outsource our responsibilities to machines,” she says. “We must hold on ever tighter to human values and human ethics.” More relevant now that nVidia are trialing ML-based self-driving cars in the US…

‘Mathwashing,’ Facebook and the zeitgeist of data worship
Fred Benenson: Mathwashing can be thought of using math terms (algorithm, model, etc.) to paper over a more subjective reality. For example, a lot of people believed Facebook was using an unbiased algorithm to determine its trending topics, even if Facebook had previously admitted that humans were involved in the process.

Build a Better Monster: Morality, Machine Learning, and Mass Surveillance
We built the commercial internet by mastering techniques of persuasion and surveillance that we’ve extended to billions of people, including essentially the entire population of the Western democracies. But admitting that this tool of social control might be conducive to authoritarianism is not something we’re ready to face. After all, we’re good people. We like freedom. How could we have built tools that subvert it? As Upton Sinclair said, “It is difficult to get a man to understand something, when his salary depends on his not understanding it.” I contend that there are structural reasons to worry about the role of the tech industry in American political life, and that we have only a brief window of time in which to fix this.
