US EIA Last year, the US saw its lowest carbon emissions since 1994, continuing a downward trend that began in 2008 during the economic crisis. It marks the second year in a row that carbon emissions have dropped despite a growth in gross domestic product. Prior to the last few years, economic growth had been closely tied to increased carbon emissions. The US Energy Information Administration released the data yesterday after having taken a bit of an unwanted break during the government shutdown. In analyzing the data, it identified a variety of causes for the drop in carbon emissions. As shown above, population size and economic activity both grew last year, which would normally push emissions up. But the energy required for that economic activity dropped, and the carbon intensity of the energy supply dropped as well. Combined, those two factors more than offset the economic growth. One of the simplest factors behind the lower energy use was a relatively warm winter at the start of 2012, which lowered residential energy demand significantly. Transportation also managed to contribute. Although miles travelled held steady, the turnover in the vehicle fleet brought more energy-efficient cars onto the road, meaning that it took less fuel to do all that travel. Another contributor is the turnover in electrical generation. Coal use dropped dramatically, replaced by a combination of natural gas and wind power. A drop in manufacturing contributed to a slight drop in overall energy use. Read 2 remaining paragraphs | Comments

US carbon emissions hit lowest level since 1994 despite economic growth
Windows 8 was an ambitious operating system. Microsoft’s goal was, and still is, to have a single operating system that can span the traditional PC, the tablet, and everything in between . To do this, the company introduced a new kind of application —the “Modern” or “Metro” style application. It created a new style of interaction—an edge-based UI for touch users, a hot-corner based one for mouse users. And it developed a new application launcher—the Start screen. Microsoft retained the familiar Windows desktop for running traditional mouse and keyboard driven Windows software. Windows 8 worked. It was a viable operating system, and in broad strokes, it fulfilled Microsoft’s dream of one operating system for tablets and PCs. But Windows 8 was far from perfect. Its problems were in three main areas. Read 91 remaining paragraphs | Comments
After the customary six months of incubation, Ubuntu 13.10—codenamed Saucy Salamander—has hatched. The new version of the popular Linux distribution brings updated applications and several new features, including augmented search capabilities in the Unity desktop shell. Although Saucy Salamander offers some useful improvements, it’s a relatively thin update. XMir, the most noteworthy item on the 13.10 roadmap, was ultimately deferred for inclusion in a future release. Canonical’s efforts during the Saucy development cycle were largely focused on the company’s new display server and upcoming Unity overhaul, but neither is yet ready for the desktop. Due to the unusual nature of this Ubuntu update, this review is going to diverge a bit from the usual formula. The first half will include a hands-on look at the new Unity features. The second half will take a close look at the Ubuntu roadmap and some of the major changes that we can expect to see over the course of the next several releases.
