Ammonia Leak on Station
colchrishadfield: Station’s power relies on ammonia coolant. A few hours ago, we determined that the ammonia was leaking out of the Station and into space. At the analyzed rate, one of the Station’s cooling loops could shut down within 48 hours. It is a serious situation, but between crew and experts on the ground, it appears to have been stabilized. Tomorrow we find out for certain.

rogueleaderr: I make pretty heavy use of EC2 spot instances, which as you know can terminate at any time with no warning. In order to get my spots back up ASAP, I’d like be notified when they terminate… This looks super useful.

adamlaiacano: I’m happy to finally give Sifter a name and a home. It’s a multi-armed bandit (MAB) API for testing web pages, optimizing which version (“arm”) of the test gets displayed. These arms could be article titles, ad positions, logos, colors, etc. Here’s the gist of how how a MAB test works: A user…
Scientists explore the illusion of memory
columbiascience: A memory might seem like a permanent, precious essence carved deep into the circuits of the brain. But it is not. Instead, scientists are discovering that a memory changes every time you think about it. “Every time you recall a memory, it becomes sensitive to disruption. Often that is used to incorporate new information into it.” That’s the blunt assessment from one of the...

Sea-level rise: Where we stand at the start of...
columbiascience: This is Part 2 of my thoughts on the state of sea-level research. Here is Part 1. Sea-level cycles? A topic that keeps coming up in the literature is the discussion on a (roughly) 60-year cycle in sea level data; a nice recent paper on this is Chambers et al. in GRL (2012). One thing I like about this paper is its careful discussion of the sampling issue of the tide gauges,...

chartsnthings: Last week I posted a video from Jeremy White, loosely describing how he turned LIDAR data into a stunning model of Tunnel Creek. But more modeling yet went into showing exactly where the avalanche happened and how it traveled. My colleague Graham Roberts added trees, elevation lines and an…
