NASA Nebula Services/Platform Stack — The NEBULA platform offers a turnkey Software-as-a-Service experience that can rapidly address the requirements of a large number of projects. However, each component of the NEBULA platform is also available individually; thus, NEBULA can also serve in Platform-as-a-Service or Infrastructure-as-a-Service capacities. Bundles RabbitMQ, Eucalyptus, LUSTRE storage, Fabric deployment, Varnish front-end, MySQL and more. (via Jim Stogdill)
A Short History of btrfs — Now for some personal predictions (based purely on public information – I don’t have any insider knowledge). Btrfs will be the default file system on Linux within two years. Btrfs as a project won’t (and can’t, at this point) be canceled by Oracle. If all the intellectual property issues are worked out (a big if), ZFS will be ported to Linux, but it will have less than a few percent of the installed base of btrfs. Check back in two years and see if I got any of these predictions right!
Exponential Decay of Life — This startling fact was first noticed by the British actuary Benjamin Gompertz in 1825 and is now called the “Gompertz Law of human mortality.” Your probability of dying during a given year doubles every 8 years. For me, a 25-year-old American, the probability of dying during the next year is a fairly miniscule 0.03% — about 1 in 3,000. When I’m 33 it will be about 1 in 1,500, when I’m 42 it will be about 1 in 750, and so on. (via Hacker News)
The growing role of software architects: “Architecture has become much more interesting now because it’s become more encompassing," says Neal Ford, software architect and meme wrangler at ThoughtWorks.
