SaaS is Green

I usually keep my day job within the 9 to 5, but couldn't help thinking about a recent advertising campaign from a Software as a Service (SaaS) company with which I am intimately familiar. NetSuite has claimed that a company going SaaS will save an average $10 300 USD per year in energy bills. These savings result from removed server and ventiliation costs. With over 6 000 customers, total savings are $61 million per year. This is equivalent to 595 million kilowatt-hours (kWh) annually, or nearly 423 000 metric tons of carbon dioxide, or 1 million barrels of oil, or the average electricity consumption of 56 000 homes a year.

For the sake of the environment, wouldn't you turn off your servers and let NetSuite host your business? For me, it takes a little more than those numbers alone. However, I commend the company for shrewd advertising! Perhaps future green energy subsidies in the US will tip the scale. Regardless, this is a very interesting topic given my vested interest in the industry!

Profanity for Pain Relief?

Thanks to this recent study, now we all have an excuse to swear! According to the findings, cursing not only is an expression of agony, but also a means to pain relief. I must admit my reservations about the experimental results. In a race to see who could keep their hands in uncomfortably cold water, subjects were allowed to mutter an expletive of their choice or use a neutral word. IMHO, the free use of profanity in the experiment -- as opposed to any social situation -- could have created intrigue or amusement in the swearing subjects, which in turn swayed the results in thier favour.

However, I did like Steven Pinker's theory that "swearing taps into the defensive reflex in which an animal that is suddenly injured or confined erupts in a furious struggle, accompanied by an angry vocalization, to startle or intimidate an attacker."

What's the verdict? Cursing is good for you if you mean it with vengeance. Don't over do it though, as the soothing effects will wear out if swearing becomes a routine lacking in emotion.

Whale Watching Gone Wrong

Let me be the first one to tell you that relocating for work is not for everyone. The amount of time and effort required is unbelievable, as you can judge from my lengthy lay-off on this blog. Now that my wife and I are ready to explore Sydney, we took to the sea in whale watching. It turned out that whale watching like relocation, is also not for everyone, especially those with weak stomaches.

I ended up seeing a whale tail for three seconds, but paid the price with three bags of vomit to go with four hours of seasick nausea. In my defense, I have never been sick at the sea. This time was different though as practically everyone else had at least a bag-full in his hand. Fortunately, the tour operator offered us a 50% refund and a free second trip. I suppose many people had complained after the ill-fated voyage. Missing out on humpbacks and blues the first time around, I am determined to sign up for round 2. As for my wife? Suffice to say she will never set foot on a whale watching boat again. Before my next "suicide mission" however, I did some research to ensure I will be prepared:

What is it, really?

In simplest terms, seasickness is a form of motion sickness.


When our eyes, inner ears, muscles, and joints simultaneously send mixed signals to confuse our brain. The clash of sensory information is passed along to the area postrema, which also controls vomiting. As for my case at sea, my eye saw the static horizon and the stationary interior of the boat while my inner ear and body felt the rolling of the waves.


  • Generally feeling unwell and weak
  • Nausea
  • Dizziness
  • Hyperventilating
  • Slight sweating leading to clammy skin
  • Excessive production of saliva
  • Losing colour in the face or turning red
  • Vomiting

Why Vomit?

No one knows for sure. One theory suggests that the vomiting response is caused by the brain’s futile attempt to rid the body of a perceived poison. Laboratory animals whose labyrinths (fluid-filled canals in the inner ears) are surgically removed are less likely to vomit when they ingest poison. Beware of excessive vomitting, as it can lead to dehydration, exhaustion and a dangerous drop in blood pressure.

How to prevent/soothe seasickness

  • Get plenty of rest prior to the trip. Physical well being helps prevent seasickness.
  • Choose seats with the smoothest ride: usually centre of a boat and avoid going under deck.
  • Stay busy and keep your mind occupied. These are perhaps the best ways to avoid seasickness.
  • Get some fresh air and look into the distant horizon.
  • Lie down and avoid turning your head to swirl the fluids in the Labyrinths.
  • Take deep breaths and drink fluids periodically.
  • When on deck, face forward (rather than to the side).
  • Try an anti-seasickness wristband, which sends electrical currents to the median nerve in your wrist. Apparently, the wrist has an acupuncture point that prevents nausea and vomiting.
  • Take medication prior to the trip.


Medications are preventive, not curative. They either calm the nerves of the inner ear or soothe the brain’s vomiting centre. However, most motion sickness pills are only effective if they are taken before you feel sick. Take them 30 - 60 minutes before a trip to allow adequate absorption. Motion sickness pills often can induce drowsiness as a side effect.


Seasickness can strike anyone at any time. By taking the proper precautions however, you need not fret about going out to the beautiful sea. I know I won't!
