Just because you follow something on Twitter or Facebook does not mean you agree with or support it. Surely it makes sense to also follow the enemy/opposition/competition just to get more of an insight into what they are doing. So, it would make sense for Obama and/or his staff to follow the Tea Party.

They must be small emails if someone can send them in tweet.

There have been at least 2 well publicised cases of this in the UK, but on the railway not airlines. In the first, someone had a very cheap point-to-point fare and when they got off the train one stop to early they were charged as though they had no ticket. The second involved someone with an advance (ie allocated seat, specific train etc) ticket who got a lift to the stop after the origin shown on the ticket and again they had to pay full fare for the journey actually made.

One way round this issue, from the airlines point of view would be for them to charge the passenger for the actual flight taken - NY to SF in the case outlined - if both that flight would have been more expensive than the one booked and the passenger does not use the extra leg(s). I suspect most flights are booked with credit cards, so the airlines could do the same as hotels are just make an extra charge if the final legs are not used.

That is not the only way that (some) banks are incompetent at security. Their 'secure' internet banking sites only support SSL3 & TLS1.0, they prefer RC4 ciphers and do not offer any ciphersuites using PFS.

As the article states, currently you have to log in to each hotspot individually. Are there ant plans to implement the protocol which enables you to migrate between hotspots in the same way as you move between cell towers, with each hotspot handing over your connection to the next? This could be useful for pedestrians in city centres, shopping areas etc and would relieve the load on the 3G networks in areas where lots of people are using data connections on their mobile phones. So that as you move between shops you do not have to keep logging in to a different hotspot.

No, the solution is to only check SPF and DKIM at your external borders (ie incoming mail on servers listed in your MX records). Internal servers should not be checking SPF or DKIM,

By the time DST starts, it is already light past the time for getting home for work, and when DST ends it is starting to get dark at go-home time. During the summer it would be light during both morning and evening commute, and in winter it would be dark irrespective of DST. It is only during the few weeks around the clock changes that it affects whether the commutes are in daylight or darkness. Also as others have pointed out, the clock changes are at the time of year when it is getting light/dark during the morning/evening commute which leads to having to two periods each years of suffering the sun just over the horizon during each commute.

No. Most of (Western) Europe should be on GMT/UTC. The timezone system is based on the sun being at its highest point within 30 minutes of noon local time, with it being at exactly noon at the 15N degree longitude lines. So it is continental Europe that should change to the 'natural' timezone rather than the UK changing to CET.

So just have 2 sets of doors and arrange so that they cannot both be open simultaneously - ie an airlock type system. The first set of doors is open and the second closed. People pass through the 1st door, the door closes and the 2nd door opens to allow the people to exit. The second door will not close (and the first remains closed) while there is anyone in the area between the doors. This means that if someone does try to go the wrong way, they will have to turn back and exit through the door they entered by.

If VPN use impedes the enforcement of geo-blocking then the answer is very simple - do not try and use geo-blocking. Restricting where content may be viewed is a concept which should have passed its 'sell by date'.

Why do you need Exchange Server on the back end to handle office? Office works fine on a standalone PC, SOHO users just have it running on a single PC or use windows shares (without a domain controller) to share documents. Office documents can be stored on any shared file system and sent/received by any email system. So exchange server is not needed to support office.

But could they order that the unopened box be shipped to the USA, where it will be forced open by US law enforcement and the contents examined?

If BBC iPlayer were to have the old episodes available, rather than its usual habit of removing programmes N days after broadcast, then there would be no incentive for fan and torrent sites to 'pirate' them.
