Dear Norwegian, our thing is over

Dear Norwegian,

I am a frequent traveller, and I have been one of your loyal customers for about ten years. I have always experienced excellent service from you, and I have always recommended you to all my friends and family. I used to be one of your greatest fans. At least this was the case until I came to the gate of flight DY1550 from Oslo to Budapest on 25 September:

No, email is not a collaborative editing solution—A comparison of the state-of-the-art

If you have co-authored at least one document in your life, you have probably experienced the pain of merging changes manually, especially when these changes are sent as email attachments.

Nowadays there are multiple collaborative editing solutions that enable merging changes automatically. Unfortunately, many professionals are not aware of the capabilities offered by these solutions and keep sending changes as email attachments and merging them manually. Believe it or not, these professionals include software engineers and computer science researchers.

I think we can do better than that…

The Chocolate-Hazelnut Spread Experiment

Back in 2010, I found myself explaining why the Italian chocolate-hazelnut spread Nutella1 is better than its Norwegian imitation competitor Nugatti to my colleagues at the University of Bergen. Yes, like most Italians, I often brag about Italian food.

One of my colleagues challenged me: “I bet what you want that if I give you a slice of bread with Nutella and another one with Nugatti, you will not recognise the difference.”

I answered: “I bet what you want that I will recognise the difference between Nutella and three other spreads, while blindfolded.”

A few weeks later, I ran the first chocolate-hazelnut spread test at the University of Bergen. The test aimed at verifying if it is possible to recognise chocolate-hazelnut spreads while blindfolded.

We can put an end to imperial units

“In metric, one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie1 of energy to heat up by one degree centigrade—which is 1 percent of the difference between its freezing point and its boiling point. An amount of hydrogen weighing the same amount has exactly one mole of atoms in it. Whereas in the American system, the answer to ‘How much energy does it take to boil a room-temperature gallon of water?’ is ‘Go fuck yourself,’ because you can’t directly relate any of those quantities.” Wild Thing by Josh Bazell.

I have not read Wild Thing, and I do not have any idea about who Josh Bazell is, but I love this quote. It brilliantly summarises how superior the International System of Units (i.e., the modern form of the metric system) is to the system of imperial units, as shown in the following illustration:

  1. One may argue that calorie is not a unit of the metric system. In the International System of Units, which is an evolution of the metre-kilogram-second (MKS) system of units, which in turn is a variant of the metric system, both mechanical and thermal energies are measured in Joule. However, in the centimetre-gram-second (CGS) system of units, which is another variant of the metric system, the thermal energy is measured in Calories. Therefore, I would still consider Calorie as one of the units of the metric system, although not of the International System of Units. Besides, I do not think Josh Bazell aimed at being scientifically rigorous, so I would excuse him for not clarifying which variant of the metric system he refers to.
