I have a Plantronics Focus UC headset that came with a bluetooth ver 4.0 USB dongle. I tried pairing the headset directly to to my laptop via the built in bluetooth 2.1 hub and it sounded flat. I then tried the Bluetooth 4.0 dongle supplied with the plantronics wireless headset and the sound was completely different (cinema quality HD). I suspect those complaining about the poor audio quality of bluetooth on their wireless headset either have a hub or headset that is bluetooth 2.1->3.0 and not 4.0 on or better on both sides.
Wrong, deleting official US federal emails is illegal, being careless is negligence and also illegal. Negligence is not an excuse when it comes to this specific mater because every US official would accidentally be deleting official emails.
Just the political elites doing what they do irrespective of the skill set of people they are employing. People keep banging on about corruption in some third world nation when corruption is well and truly alive in your back yard.
I gave up when I started realising the Olympics stopped being about sportsmanship and your average sports person and all about who has the best genetic freaks and the smartest drugs and the best corporate sponsor. For example they now know that you can give enhancement drugs to an athlete withdraw them months even years before the event and the athlete will still retain some of the advantage of taking the drugs. So when you hear of past drug cheats getting back into the Olympics with times that are almost the same as when they were a drug cheat, well now you know why.
Also this is a good lesson for those using cloud storage, have more than one and mirror all your personal files across both and "with different passwords" . If one cloud provider does lose all your data you have a fall back.
I think it is about time we all agreed the ever growing password and 2 level checking even with a mobile is verging on becoming a complete fail. What we need is an open security standard that not only securely transmits data but allows a user to use their web services "without a password". Im thinking some type of smart dongle with a rotating 2048 bit key with a fingerprint reader built in that can scan up to 10 finger prints (users can have a multi fingerprint login sequence). The dongle should work with mobiles and other PC related devices and even door locks. This way it removes the security key layer away from the PC and the telco networks and isolates the device from open Internet access (device is a 2 part connection when plugged in in that the device itself never electrically connects only the io part does)
From experience with dealing with chinese OEM's and the spy v spy nature of china the code could have been added by a chinese spy working as an employee. We have had reports from our chinese based factories of government officials asking for code to be tampered with but usually not on the export items but on the local stuff. So yes if you are buying consumer electronics made for the chinese mainland market with a english language update you may find the device has 2-3 layers of back doors built in.
