- Andrew Ng (Wired) — I think self-driving cars are a little further out than most people think. There’s a debate about which one of two universes we’re in. In the first universe it’s an incremental path to self-driving cars, meaning you have cruise control, adaptive cruise control, then self-driving cars only on the highways, and you keep adding stuff until 20 years from now you have a self-driving car. In universe two you have one organization, maybe Carnegie Mellon or Google, that invents a self-driving car and bam! You have self-driving cars. It wasn’t available Tuesday but it’s on sale on Wednesday. I’m in universe one. I think there’s a lot of confusion about how easy it is to do self-driving cars. There’s a big difference between being able to drive a thousand miles, versus being able to drive anywhere. And it turns out that machine-learning technology is good at pushing performance from 90 to 99 percent accuracy. But it’s challenging to get to four nines (99.99 percent). I’ll give you this: we’re firmly on our way to being safer than a drunk driver.
- Google Cloud BigTable — Google’s BigTable, with Apache HBase API, single-digit millisecond latency, and “fully managed”. G are hell-bent on catching up with Amazon and Microsoft at this cloud serving thing.
- Call Me Maybe: Aerospike — We’re setting a timeout of 500ms here, and operations still time out every time a partition between nodes occurs. In these tests we aren’t interfering with client-server traffic at all. Aerospike may claim “100% uptime”, but this is only meaningful with respect to particular latency bounds. Given Aerospike claims millisecond-scale latencies, you may want to reconsider whether you consider this “uptime”.
- 31 Continuous Delivery Architectures (Slideshare) — from a vendor, so one name crops up repeatedly (other than “Jenkins”), but it’s still good devops voyeurism/envy.
Exploring Clojure as a tool to generate music, visual art, poetry, and dance.
Clojure is gaining traction and popularity as a programming language. Both enterprises and startups are adopting this functional language because of the simplicity, elegance, and power that it brings to their business. The language originated on the JVM, but has since spread to run on the CLR and Node.js, including web browsers and mobile devices. With this spread of practical innovation, there has been another delightful development: a groundswell of people making art with Clojure.
Getting creative with Clojure
Creative Computing combines the power and engineering of the computer with the artistic inspirations of humans. People are using Clojure as a tool to generate music, visual art, poetry, and even dance. This ability to harness technology for creative purposes is both exciting and important. For it not only touches the heart and inspires existing technologists, but it also transcends all barriers. Art is a gateway to bring new people, young and old, from all walks of life, to the field of programming.
Let’s explore some of the areas of Creative Computing with Clojure, and showcase some inspiring examples from a selection of artist/programmers. We’ll look at projects that touch on music, art, games, writing, and even robots.
