Skype Outage Hits Users Worldwide 167

Hugh Pickens writes "The LA Times reports that millions of Skype phone users worldwide couldn't make calls or were dropped in mid-conversation because of a network connection failure that began about 9 AM Wednesday PST. 'For a communications system this large to go down, it's almost unheard of,' says Charles S. Golvin, a Forrester Research analyst. 'Usually when phone lines are disrupted, the blackout is confined to a specific geographical area. This is worldwide.' In theory, Skype, which is based on peer-to-peer networking technology, shouldn't see an outage, but that is not really the case — the company has a massive infrastructure that it uses for purposes such as authentication and linking to the traditional phone networks. 'The outage comes at a time when Skype is starting to ask larger corporations for their business,' writes Om Malik. 'If I am a big business, I would be extremely cautious about adopting Skype for business, especially in the light of this current outage.'"

GM Loses Money On Every Volt Built 471

thecarchik writes "Doug Parks, vehicle line executive for the 2011 Chevrolet Volt, GM's range-extended electric vehicle, confirmed Tuesday that the company loses money on every Volt it sells. The expensive 16-kilowatt-hour battery pack, which likely costs GM somewhere between $8,000 and $12,000, is clearly too expensive to let the company build hundreds of thousands of Volts right away. Just 10,000 Volts will be built in 2011, though GM is working to increase that number. GM plans to chip away incrementally to lower the costs of the specialized components in the Volt, especially the power electronics. The price of consumer lithium-ion cells has fallen 6 to 8 percent annually since their 1989 launch; the large-format cells in automotive packs seem likely to follow the same curve and as costs are lowered the Volt may stop being a loss for the company."

Chip Allows Blind People To See 231

crabel writes "3 blind people have been implanted with a retinal chip that allowed them to see shapes and objects within days of the procedure. From the article: 'One of the patients surprised researchers by identifying and locating objects on a table; he was also able to walk around a room unaided, approach specific people, tell the time from a clock face, and describe seven different shades of gray in front of him.'"
