Nota Bene

Hi folks!

Phew. After a few days’ rest and recuperation since last week’s merciless working schedule at the WEF, I do believe I’ve recharged my batteries sufficiently to be able to continue my notes on my four-day stay in Davos, where the WEF took place.

First – rewind: some history…

So, just why is it that this famous yearly forum – infamous to some, helpful to others – takes place in this particular tiny village in Switzerland?

I’ve got two versions…

As many will already know, the number 2017 is a prime number; that is, it can be divided without a remainder only by itself and 1. Must say, the theory of prime numbers is a wholly interesting one and an extremely useful one too, as any cryptographer will tell you :).

But today I’ll be writing about something different. See, based on the fact that 2017 is prime – or ‘simple’ – many, myself included, are anticipating a simple, straightforward and calm year 2017, especially since 2016 was a bit of a rotter. Let me show you why.

Like I said, prime numbers are those that can only be divided by themselves and 1 without leaving a remainder. Non-prime numbers are called composite numbers, incidentally.

Turns out that 2016 is not only a composite number but a very composite number! It has a whole eight divisors. Grab a calculator your smartphone and test it for yourself:
2016 = 2 * 2 * 2 * 2 * 2 * 3 * 3 * 7

Whoah! Even the quantity of divisors is anything but simple, since 8 = 2 * 2 * 2.

So what about other years? Was 1917, the year of the Russian Revolution, a ‘prime’ year, for example? No, it wasn’t. 1917 = 3 * 3 * 3 * 71. Just four divisors, but they’re kinda poignant – and prophetic of nothing much good.

So what about other very prime/simple years, and other very non-prime/non-simple ones? Ok, let’s narrow this down a bit to 1980 through present day…

Prime/simple years:
1987
1993
1997
1999
2003
2011

And in the near future there are a few more prime/simples:
2027
2029

(eek, that’s a lot of non-simple years until then)

The most non-prime/non-simple years were:
1984 = 2 * 2 * 2 * 2 * 2 * 2 * 31 (seven divisors)
2000 = 2 * 2 * 2 * 2 * 5 * 5 * 5   (also seven)

There were six divisors in 1980, and there’ll be six in 2025. All other years can be called semi-prime/semi-simple.

But I digress…

Now, in the popular British mathematical journal The Guardian :), readers were recently teased with a… brain teaser. In the blanks between the sequence of figures 10 9 8 7 6 5 4 3 2 1 you need to add arithmetic symbols (+, -, x, ÷, (),) – as many as you like – so as to get the number (year) 2017.

For example, if you add arithmetic signs as follows you get 817:
10 * 9 * (8 + 7 – 6) * (5 – 4) + 3 * 2 + 1 = 817

But how do you add arithmetic to get 2017?
10?9?8?7?6?5?4?3?2?1 = 2017

Come on, have a go!

As for me, in nine minutes I got the equation to equal 2017 by kinda wonky arithmetic (I made the ‘3’ and ‘2’ = ’32’!); then, in around 15 or 20 minutes I got the answer in a proper way without bending the rules. I say ‘a’ way: there are different ways of getting to 2017!

So, tried it yet?

Ok, let’s make it harder: Now take away the 10:
9  8  7  6  5  4  3  2  1 = 2017

Having a depressing January? Well don’t! Get out and about – preferably on the road! Which is just what I did. With my trusty big black suitcase…

To warm-up it’ll be Western Europe, mostly of the Alpine variety. Then it’ll be a healthy dose of equatorial/tropical travel, then back to Europe, then back home for a bit. It’s going to be fun, I can tell, and I’ll be sharing that fun, plus pics thereof, as I go along (I’ve already found the ‘masterpiece’ button:).

All righty. The Christmas tree’s been taken down, the New Year merriment appears to have vanished, and it’s still very cold and snowy. So what better time for a bit of taking stock in the calm, cold light of day January. Therefore, as per tradition (2015, 2014, 2013), herewith, a cursory glance back over my personal highlights my year…

The first thing I can say is that it was a relatively calm year. In all 92 flights – lagging quite a bit behind the previous year’s record of 116. All the same, a couple of months were very intense aviation-wise: 12 flights in March and 13 in September. On the other hand, I had my first whole month without flying anywhere at all in many years: November.

Now – a bit more detailed:

Happy New Year folks, and hope you all had great holidays!

You won’t believe this… but this post is about… RED SQUARE! // Incidentally, the square I consider to be the most beautiful spot in Europe!

I hadn’t been in downtown Moscow on New Year’s Eve since… oooh, 15 years ago! Yep – 2001 was the last time, on Pushkin Square watching the fireworks. But I’d never been on Red Square on New Year’s Eve. What?! So this year I decided to make amends…

So how was it? Well, actually, my overall impressions were… mixed. And it’s those mixed impressions that I’d like to share with you today.

I regularly get asked which books should be read to build up a successful business. Students, start-uppers, managers, business owners – everybody wants a reading list! But that’s ok, for I do have some answers. However, I don’t believe one can become a businessperson by reading certain books, no matter how highly recommended they come. Still, there are some great books out there that sure won’t do any harm reading; eight of which I’ll tell you about in this here post…

I divide business books into two major categories.

The first helps readers with what needs to be done to build up a successful business; the second – how not to do it. The boundary is often blurred, but taken together books from both groups can help readers avoid both spending valuable time and resources on re-inventing the wheel again and again, and make the exciting business of… building a business a constant struggle.

Actually, there’s also a third category of books – works by legendary captains of business or government leaders, which instruct by example how things should be done. Such books are normally rather general as they cover such a broad range of business problems and unpredictable unexpectednesses, while also demonstrating limitless possibilities – albeit hazily. They don’t contain hands-on action plans, but they’re still well worth a read to get valuable overarching insights.

Many of the books in my list here were written quite a while ago – some even in the last millennium – so whole new industries and technologies of the 2000s are either hardly touched or aren’t touched at all. All the same, the books are still relevant to modern times; their main ideas can easily still be applied to today’s digital realities. We’re living in an era of new technologies, but man’s nature is still the same, and folks tend to repeat the same or similar mistakes. Not all folks, mind: others do things right and their companies become widely recognized and respected leaders. Which is what I hope for everyone.

All righty – here we go. Happy reading – of this post and then the books detailed in it!…

Jim Collins. Good to Great: Why Some Companies Make the Leap…And Others Don’t

details

I’d call this the most important book in my business library. In plain language and with lots of practical examples, the author convincingly analyzes the traits commonly found in various types of leaders. This book is one of the few in my first category mentioned above: How to build a great business.

Once again, it’s the last month of the year already. The reservoir outside my office window has long frozen over (with fishermen sat atop it with their rods poking through holes made in the thick ice), and it’s brrrrr freezing, it goes without saying. There’s the somewhat disturbing crackle of the anti-ice chemical pellets underfoot and under-wheel; there are traffic jams seeming to be longer than usual; and there are days when you don’t set foot outside in daylight (it’s dark late in the mornings and early in the evenings). Business-wise, December is also a month for summing up, for progress reviews, for stocktaking, and for finalizing budgets and plans for the future.

So yes, December can be a dark, dull and wearisome month. For us at KL though, there’s one event to make up for all that. Of course it’s our annual Christmas/New Year blow-out. A small get-together – of ~2500 KLers and guests from around the world – for some serious festive letting down of the hair, kissing under the mistletoe and all that. And this year it happened last Friday…

Hi folks!

Herewith, the next installment in my ‘Uh-oh Cyber-News’ column – the one in which I keep you up to date with all that’s scarily fragile and frailly scary in the digital world.

Since the last ‘Uh-oh’ a lot has piled up that really needs bringing to your attention. Yep, the flow of ‘Uh-ohs’ has indeed turned from mere mountain-stream trickle to full-on Niagara levels. And that flow just keeps on getting faster and faster…

As a veteran of cyber-defense, I can tell you that in times past cataclysms of a planetary scale were discussed for maybe half a year. While now the stream of messages is like salmon in spawning season: overload! So many they’re hardly worth mentioning as they’re already yesterday’s news before you can say ‘digital over-DDoSe’. “I heard how they hacked Mega-Corporation X the other day and stole everything; even the boss’s hamster was whisked away by a drone!”…

Anyway, since the stream of consciousness cyber-scandals is rapidly on the up and up, accordingly, the number of such scandals I’ll be writing about has also gone up. In the past there were three of four per blogpost. Today: seven!

This is a veeerrrry strange place. It’s a place that’s completely isolated from the outer world – isolated by man, that is (not naturally isolated like, for example, Kamchatka). In fact, more isolated (by man) than the Chernobyl or Fukushima nuclear power plants. To get into it and get over to those there hills on the horizon is completely impossible, even theoretically – neither by ground nor air. You’d be shot!

An absurd paradox of paradoxes, if ever there was one: they call this place ‘demilitarized’. Turns out to be one of the most heavily militarized strips of land on the planet! Yes folks, this is the Korean Demilitarized Zone – the DMZ.

After what has possibly been my longest ever ‘stay’ in Moscow (er, but I ‘live’ here:) – a full month! – I recently resumed my habitual routine of not being in the same place country for long. It’s good to be ‘back’; but the downtime in Moscow was great too. But I digress…

Anyway, I eased myself into the business-globetrotting thing steadily – taking not a full leap to the other side of the world, but a mere little jump not all that far away, relatively. And the first thing I noticed after landing that made me all curious was this here sign next to the lift in the offices we were visiting:
