An anonymous reader writes "Linux distributions track upstream projects, releasing a particular version with each official release. But how far behind the latest versions do these releases linger? Scott Shawcroft did an interesting new study into this relationship between distributions and upstream projects. Shawcroft says: 'Over the last 10 months I've been working on Linux evolution research. Similar to distrowatch, I track the current versions of packages in a number of distributions and the current upstream version. Based on that data I then graph a number of metrics to understand the relationship between upstream and downstream.' His presentation on the topic scheduled for [this] week's open source convention, OSCON, should provide an interesting insight into that relationship. Currently he is tracking 20 projects including the Linux kernel, Firefox, GCC, OpenSSH and GNOME on Arch, Debian, Fedora, Gentoo, openSUSE, Sabayon, Slackware, and Ubuntu."

There are many initiatives to bring tech to developing areas of the globe; things like OLPC, Geekcorps, and UN programs. One new approach from SolarNetOne strives to allow users in those developing areas to have access to an internet connection without having to depend on unreliable infrastructure. "Each SolarNetOne kit is a self-powered communications network. Energy is produced from a solar array sized to each locale's latitude and predominant weather conditions. The generated power is stored in a substantial battery array, and circuit breakers and electronics protect the gear from overloads and other perturbations. A basic kit includes five 'seats,' implemented as thin clients connected through a LAN to a central server. The networking gear also includes a long-range, omnidirectional WiFi access point, and a Session Initiation Protocol (SIP) device. Each kit also includes all the cables and wires required to assemble the system, so few additional materials are required for an installation."

Nancy Atkinson writes "Using a technique called pixel-lensing, a group of astronomers in Italy may have detected a planet orbiting another star. But this planet is unique among the 300-plus exoplanets discovered so far, as it and its parent star are in another galaxy. The Andromeda Galaxy, to be exact. Technically, the star in M31 was found to have a companion about 6 times the mass of Jupiter, so it could be either a brown dwarf or a planet. But either way, this is a remarkable feat, to find an object of that size in another galaxy."
