Submission + - What's killing your Wi-Fi? (pcpro.co.uk)

Barence writes: "PC Pro has taken an in-depth look at Wi-Fi and the factors that can cause connections to crumble. It dispels some common myths about Wi-Fi problems — such as that neighbouring Wi-Fi hotspots are the most common cause of problems, instead of other RF interference from devices such as analogue video senders, microwave ovens and even fish tanks. The feature also highlights free and paid-for tools that can diagnose Wi-Fi issues, such as inSSIDer and Heatmapper, the latter of which maps provides a heatmap of Wi-Fi hotspots in your home or office."

Submission + - Amazon Math Trick "Doubles" Kindle Battery Life (cnet.com) 2

destinyland writes: Amazon just doubled the reported battery life for their Kindle digital readers — but they did it by cutting the estimated daily usage in half! Monday Amazon's competitor, Barnes and Noble, had released a new touch-screen version of their Nook reader, and C|Net notes that apparently Amazon "took issue with how its competitor was calculating and presenting its battery life numbers." When Barnes and Noble claimed that the Nook's charge lasted twice as long based on a half hour a day of usage, Amazon simply recalculated the Kindle's battery life using the same formula. By Wednesday, Barnes and Noble was insisting that the Nook's charge still lasted twice as long as the Kindle's, "If that’s true, then Barnes and Noble mangled the launch of their touch-screen Nook," reports one Kindle blog, "by botching their description of one of its main selling points."
