An anonymous reader writes "Nokia's recently released Internet Tablets have proved popular. But Nokia has failed to properly provide for software updates for its customers. The Nokia update servers for the tablets have proven to be woefully inadequate, causing its customers tablets to crash during updates, and forcing them to BitTorrent and other servers for updates."

Data Center Startup Re-ignites AC vs. DC Debate -> 0

1sockchuck writes "The data center industry has been actively discussing whether using DC power distribution would improve the energy efficiency of mission-critical facilities. The AC versus DC debate is likely to intensify with the launch of Validus DC Power, a Connecticut startup that came out of stealth mode yesterday with $10 million in VC funding. Validus uses -575V DC for power distribution and uses a converter to provide -48V DC to servers. Most newer data centers use AC for power distribution, but The Green Grid is among those suggesting DC distribution can reduce power loss from AC-to-DC conversions within the data center. Other industry players, including APC-MGE, say DC only offers improvements when compared to older AC equipment, and that recent improvements in UPS efficiency allow AC distribution to match DC for energy efficiency. With the recent focus on power and cooling chalenges in data centers, the debate (which dates back to Edison and Tesla) will likely get louder in coming months."
