Google and Mattel pull the View-Master into virtual realityGoogle and Mattel pull the View-Master into virtual reality – Let’s recall the iconic View-Master toy that first launched in 1939 — it used small colored film that brought images to 3D life. Now, it’s getting a massive overhaul with the help of Google and its Cardboard VR (virtual reality) viewer.

Electronics and cold: A dangerous mix

As we all endure these cold temperatures, it can be easy to forget that some of the stuff we carry with us is isn’t quite as hearty. Notably, electronics can be damaged quite easily and seriously in this weather. It’s not the cold itself that is always a problem (although it can be), but instead it’s the temperature change from cold to warm which triggers condensation inside the device.

That fogging of your glasses when you come in from outside is water condensing onto the cold glass surfaces. This same thing takes place unseen inside your phones, tablets, laptops, cameras, and other electronics. Because we all know that water and electronics do not play well together, this puts your data as well as the device itself at risk.

We would never try and use our device after it had fallen into water, but just coming in from the outside can result in enough water inside the device to cause the same damage. To the right you’ll see the result of actual water damage inside a MacBook… an extremely expensive repair (click the photo for a better view).

 

Condensation/water isn’t the only killer here. Cold batteries will die faster, cold hard drives can have trouble spinning and can damage your valuable data, cold LCD displays won’t look or function right, and the sudden change from cold to hot as internal components heat up when powered on can cause permanent damage. While too much heat can hurt electronics, too much cold has plenty of negative effects as well.

So… what to do to keep your device and data safe? Here are the best practices:

  • If at all possible, don’t let your electronic devices get cold in the first place. This means not leaving them outside, or in your car. If you have to carry your electronics for an extended distance from one building to another, bundle them up inside a bag as well as you can to insulate them from the cold. Wrapping them in a towel, shirt or blanket isn’t unreasonable given the bitter cold temperatures lately.
  • If it’s too late and your electronic device has already gotten cold, don’t turn it on. If possible, remove the battery since these days “off” isn’t really powered off. If you’ve gotten lucky and condensation hasn’t damaged it yet, the moment of powering it up and sending electricity through the entire device is the most likely moment of death. The safest thing to do is let it sit in a dry, room-temperature environment as long as you possibly can. Just because it has reached room temperature and is dry outside does not mean there has been time for all the condensation to evaporate inside. This can take hours. Obviously, prevention is more convenient and a much better option.
  • As always: make sure you’re keeping your data on Middfiles instead of storing your files locally on the device. That way if the worst happens and your device fails, at least your data is still safe. Just backing up once a week/month is still living dangerously: make Middfiles your default location for storing and opening your files and you’ll be protected in the event of this and many other things that can go wrong.

Wireless Network Changes

Greetings!

Over the course of the next several weeks, we will be replacing the wireless networks at Middlebury. (UPDATE 03/13: The first two changes are complete. The final update is scheduled for next Wednesday, March 18th.)

What do I need to do?

Starting March 2nd, please connect to the new secure wireless network named MiddleburyCollege (like midd_secure but better). Middlebury Faculty, Staff and Students will login with your standard Middlebury username and password. Guests will need to create a Middlebury guest account and use it to connect to MiddleburyCollege. This is not a change for change’s sake – we are confident that the end result will be a wireless network that is more convenient and more secure for everyone.

Systems Maintenance Sunday, Feb 8th

During our regular maintenance window this Sunday, February 8th  we have the following activities scheduled:

 

  • Starting at 5am EST the Middlebury website, http://www.middlebury.edu, will be put into a read-only mode for approximately 5 hours for an upgrade. After the upgrade completes the site will be put into full read/write mode.
    • What’s available during this read-only period?: All publicly-accessible content on our website will be available.  Links will continue to work.  Drupal webforms are hosted on another site and can be accessed and edited as normal.
    • What’s not available during the read-only period?:  Commenting on news stories, content that requires logging in before viewing, content editing on the main Middlebury website.

 

  • The hosted Hyperion and Banner applications, including Banner INB and SSB, will be updated and unavailable between 8am and 9am EST. The development environments for those services will be unavailable between 9am and 10am EST.

 

  • Middfiles, which includes Orgs, all Classroom, and home directory folders, will be rebooted and unavailable for approximately 10 minutes starting at 8am EST.

 

  • The Exchange email environment will undergo resource reallocations impacting 8 servers. The email environment is sufficiently redundant that we expect no impact to availability during this maintenance.

 

We appreciate your patience as we continuously strive to keep our systems functioning optimally.
