Things are changing in life. One major change is that I live together with Maggie since 5 months, which means some priorities have changed. Before, meeting in virtual worlds was a big part in our relationship, but now, when we live in the same house and can sit next to each other by our computers, that has become a very small part. That also means we spend less time in Metropolis, and on social events there.
My latest major addition in Metropolis is a stub for a chemistry exhibition, temporarily located in region MB Sea 72 since 2015-03-07, but not announced before. At present there are models of the 20 essential amino acid and the hormone insulin, all in scale 10.000.000:1 (1 meter = 1 Angstrom). There are plans to add models of DNA, RNA and their constituents, carbohydrates, lipids and more basic organic molecules as well.
Lately much of my spare time has been spent digging into the OpenSimulator code and fixing a few minor things, but also trying to get a grasp on a few LSL functions unimplemented or buggy.
Today, I upgraded Maggie's and my 65 simulators in Metropolis to OpenSim 0.8.2.0 Dev PLUS Metropolis Edition  (Unix/Mono), and besides needing to tweak the scripts handling the installation some, it seems to have gone well. I always make a clean install, so probably it was good getting rid of a few caches with possibly corrupt files after a somewhat problematic upgrade to Ubuntu 14.04 recently, and some experimenting with optimizing especially thread handling for OpenSim.
One definitely good thing with the upgrade is that the handling of large varregion terrains is much improved, so the previews of such in the regions Terrains 2 - Terrains 10 are quite enjoyable now. I actually spent almost a full hour flying along the coastlines of and exploring a 2560x2560 m terrain I rezzed from the terrain rezzer in Terrains 10, displaying about as smoothly as when I first tested it with ArribaSim.
