Dell Wasn’t Joking About That 28-Inch Sub-$1000 4K Monitor; It’s Only $699 – Forbes
The P2815Q will have a full 3840 x 2160 4K resolution and launch globally on January 23. Dell hasn’t yet discussed things like refresh rate or range of inputs (I’m sure DisplayPort is a given), but they do promise the same “screen performance” as the new UltraSharp 32 and UltraSharp 24 Ultra HD monitors. That’s certainly encouraging since their UltraSharp line is normally a cut above when it comes to professional displays.

Why Some Civil War Soldiers Glowed in the Dark | Mental Floss
As dusk fell the first night, some of them noticed something very strange: their wounds were glowing, casting a faint light into the darkness of the battlefield. Even stranger, when the troops were eventually moved to field hospitals, those whose wounds glowed had a better survival rate and had their wounds heal more quickly and cleanly than their unilluminated brothers-in-arms. The seemingly protective effect of the mysterious light earned it the nickname “Angel’s Glow.”

Exponential Decay of History, Improved | Awelon Blue
Exponential decay of history is a pattern that competes with ring-buffers, least-recently-used heuristics, and other techniques that represent historical information in a limited space. Like ring buffers, exponential decay can keep useful historical information in a bounded space. However, ring buffers provide a flat history, e.g. the last ten elements (perhaps corresponding to a few seconds), which means they can quickly lose historical context (such as what was happening minutes ago, hours ago, days ago) that may be very valuable for making useful decisions. Exponential decay provides a deep history – potentially keeping years or centuries of context in a bounded volume. The tradeoff is losing much of the intermediate information.

How to Really Eat Like a Hunter-Gatherer: Why the Paleo Diet Is Half-Baked [Interactive & Infographic]: Scientific American
We are not biologically identical to our Paleolithic predecessors, nor do we have access to the foods they ate. And deducing dietary guidelines from modern foraging societies is difficult because they vary so much by geography, season and opportunity
