    RoundCube still doesn't have collapsable folders in the stable builds. And it occasionally mangles MIME delimiters in a way that makes the message unreadable. I love the interface, but it's not done yet.

    Not the SquirrelMail is the only alternative, but RoundCube is not exactly a drop-in replacement.

    Checking voicemail from email or replying to email from your phone are *not* features that you need Exchange to get. They aren't even things Exchange did first or particularly well. It's just a popular solution that other vendors (like PBX providers) advertise compatibility with, nothing more, nothing less.

    And Exchange is a nasty solution if you're not using an MS OS -- the IMAP client on your phone won't work unless someone enables it. Even if they enable IMAP doesn't work terribly well when mixed with MAPI clients or OWA. And OWA from Exchange 2007 hides about half the features (like rules and filters) if you're not browsing from MSIE. For an environment like a University, where a good 50+% of the users are likely *not* provided with a copy of Outlook (or an OS that can run it), let alone phones that support ActiveSync, it's probably not a great plan.

    I believe that lying has socially and ethically acceptable uses and that you're being both selfish and "part of the crowd" by trying to proclaim that it's not.

    But by asking why someone has a "need to be connected...at all times" shows that you're missing the point entirely. You could ask the same thing about email, or even plain old landline phones -- Facebook has perfectly valid, practical uses, just like other communications systems. People also use all three three for frivolous things like gossiping with their friends and self-promotion, and all three systems have the ability to interrupt other parts of your life.

    So ask yourself why you have a phone and an email account. Why do you need to be connected to everyone and everything at all times? Couldn't you just go see other people in person, or send them a letter. Sure, you'd like emergency services, but a police box on the corner is almost as good, a whole lot cheaper, and very unlikely to interfere with your normal life.

    I'll bet a big part of why you have phone and email services is because everyone else does, and it serves as a practical way to quickly exchange information with other people. Just like the people you're insulting for using Facebook

    There are non-electric versions of A/C, but they probably aren't a better deal for you unless you get free waste steam from some industrial process:

    Trane sells the Horizon series of absorption chillers for installations that want to capture energy from waste steam or that have unreliable electricity. They used to sell direct-drive gas-powered centrifugal chillers too, but they've gone to coupling a generator with a chiller to avoid vibration and other issues they had with the direct-drive system.

  6. Re:traction control on Ford To Introduce Restrictive Car Keys For Parents · · Score: 1

    ABS reduces stopping distances on high-traction surfaces like the highway. Even skilled drivers using threshold braking are unlikely to improve over ABS braking. And I don't even know where you got this "Locking the brakes up might stop you" idea, because that's just absurd.

    Not to mention, ABS provides increased steering response during breaking, which would allow you to go *around* the obstacle rather than into it once you determine that you can't stop in time. Try steering around something with your tries locked and tell me how that goes.

    Also, I don't know about you, but my brakes have wear indicators to let me know when they've reached the end of their effective life. So even if the traction control system contributed significantly to brake wear I would have warning of the impending failure and could have my brake pads replaced.

  7. Re:traction control on Ford To Introduce Restrictive Car Keys For Parents · · Score: 1

    ABS *does* reduce reduce average stopping distances on common road surfaces. Even for skilled drivers using threshold it would be difficult to obtain better stopping distances without ABS, let alone the average driver.

    Now there are cases where that isn't true. On surfaces covered by a low-traction but movable coating, such as loose gravel or deep snow over a higher-traction surface, ABS can increase stopping distances by preventing tries from digging through to the hard surface below.

    But even in those cases ABS can provide significant lateral stabilization and increased steering response during braking, which are valuable in and of themselves, perhaps even at the cost of some stopping distance.

    Also note that modern traction control systems can use the ABS system to limit wheel spin -- rather than simply cutting axle power you can apply braking to the spinning wheel to limit its speed, allowing the other wheel to take advantage of the existing axle power.

    I agree that having physical access to the disk allows anyone to read it, and that sensitive data should be encrypted. But that doesn't mean it isn't worth making things complicated. Set good passwords. Use BIOS/OpenFirmware/other pre-boot environment passwords to prevent non-standard booting. Lock/screw the case closed.

    Now instead of having instant, one-click access they need a password for the OS, a password for the pre-boot environment, or to physically open the case (bypassing any locks the case may include). Can they still get at the data on your hard drive -- yes. Can they still do it in under 2 minutes -- no. It may not be an important difference for a stolen laptop, but for an unattended visitor at the receptionist's desk, adding 90 seconds to the compromise time can be a big security gain.
