TunnelBear: A Personal VPN App

“TunnelBear” is a cool, free VPN app you can use to protect your laptop or phone. People need this protection when using public WiFi (such as when you’re at the airport, coffee place, or on airplanes).

Ever since that reporter got hacked on an airplane while using an in-flight WiFi service, it seems many people are telling us to use a VPN. However, they do NOT say how to get one.

For personal use, a VPN app like TunnelBear does the trick. Just search for TunnelBear on your favorite app store or browser search engine.

Q: Is the VPN client my company put on my laptop enough? A: The VPN client that is put on your laptop is used to “tunnel into” the internal network of that company. ALWAYS use that when in a public place and you are working on company business. However, your personal laptop or phone also needs a VPN. That’s where an app like Tunnel Bear comes in.

Q: What’s the catch? A: Glad you asked. The free version of TunnelBear is limited to 500MB per month. That’s plenty for email and web surfing. Not enough for streaming movies or music. If you need more data, you can buy it. (You can pay by credit card, PayPal, or jars of honey.)

Q: I’ve been using free hotspots for years without any problem. Why do I need a VPN now? A: Unfortunately, the technology for hacking WiFi has become more widespread and easier to obtain than in the past. Consequently, the risk has been increasing.

Q: What do bears have to do with it? A: The Tunnel Bear company is located in Canada. The bear motif strikes me as an expression of True North’s freedom.

Q: Are there other VPN apps? A: Yes, but I have not used them.

Q: Do you get anything out of it? A: No. Although there is a referral program that issues a custom link, I’m not using it. Just search for tunnel bear on your favorite app store or Google it.

Q: What does VPN stand for? A: Virtual Private Network

Q: What does “virtual private network” mean? A: Let’s break that down. “Virtual” means “pretend.” “Private network” means it’s separate from the public network. A VPN secures data through encryption (so outsiders cannot intercept it). It’s not really a private network, but because of the encryption it acts like it.

Q: What do tunnels have to do with it? A: It’s a metaphor. It might not be a perfect metaphor, but it’s good. When we send and receive data over the Internet, it’s broken into smaller units of data called packets. Metaphorically, each packet is surrounded by the encryption. All the packets lined up are encased by the shell that forms a metaphorical tunnel that protects the data. All metaphors break down. In this case, the encryption shell acts like a tunnel, but packets can still be intercepted. However, because the packets are encrypted, no one can read/understand the data.

Q: I’ve heard people from my company’s I.T. department use “VPN” as a verb; as in: “You’ll need to VPN into the network to access the Wiki.” Is VPN a verb? A: I have been told that any word can be verbed. However, when you read technical documentation, they will usually use the verb “to tunnel” as in, “Start your VPN client in order to tunnel into the secure network.”

Q: Seriously, can you pay with jars of honey? A: Yes, according to the pix on their web. It’s probable, however, that this is more for publicity. Not easy to pack up jars of honey and ship them.

 

Teamwork versus Cohesion — How “Let’s go bowling!” Can Actually Hurt Productivity

Every semester when we got to textbook chapter on “Understanding Groups and Teams,” I would ask the class: “What does teamwork look like?”

People really struggled with that. Participants in the class started with words like “cooperation” and “friendly.” My job as the instructor was to press the point, so I’d rephrase the question: “If you were an anthropologist from another planet and you were studying humans, how would you describe teamwork in your field notes? What does teamwork look like to an outsider?”

Again, every semester, every class would struggle with this question. And, again, as the instructor I would offer a prompt: “I think people who work in a hospital emergency room are a great example of teamwork.” Then the proverbial lightbulb would go on. Then the class members would start saying things like: Emergency rooms are made up of people who are

  • well-trained
  • execute distinct roles
  • help each other as needed
  • communicate using well-understood terms and procedures

Members of an emergency room team also share some very deep values about saving lives, treating the injured and sick, and “covering” for a co-worker who might be overwhelmed.

Then, I would add: “Emergency room teams even practice how to handle situations before they occur. Can you imagine working for a company where teams actually practiced how to do a better job together?” After that, we’d have a good discussion about how to foster genuine teamwork in the workplace.

Also, in class, we’d have to circle back to the comments about “friendliness” or, as psychologists like to call it “cohesion.” One of the things that has been well-researched is that cohesion does not by itself improve productivity. “Let’s go bowling!” “Let’s do a group activity off-site!” “Let’s get t-shirts printed up!” These are almost a cliché in organizations, but they do nothing to improve productivity in and of itself. When a group has a high level of cohesion, they are more likely to achieve the group’s goals — regardless of how well the group aligns with the organization’s goals.

In other words, increasing affinity and cohesion can actually hurt productivity when the group is unhappy, misaligned with an organization’s goals, or the front-line manager “bad mouths” upper management.

Perhaps a simpler way of looking at it is this: Teaching a group to play together well doesn’t usually help them work together well. Any manager who has a lack-luster team should strongly consider these other ways of improving morale and productivity:

  1. Clarifying roles (who does what)
  2. Training in job skills (how can we do it better)
  3. Uplifting and rewarding values such as customer satisfaction and service (aligning the group’s goals with the organization’s goals)

It should almost go without saying that any front-line leader who finds the above daunting has exactly the kind of challenge that a bowling event cannot help.

A final satirical comment: Sometimes managers will ask the team to propose a “team building” event. While indoor “skydiving” in a wind tunnel is fun, few teams are ready to try the following:
