I cordially wish you every bit of good fortune for the new year, which will be here in a while.

Besides the important and valuable possession of health, I wish that new roads will be opened to you, which will lead you in directions that are necessary for a substantial improvement. At the same time, if you happen to be in a rut, I wish that you will come out of it quickly through the appearance of such roads. Furthermore, I wish that you will have inexhaustible strength and endurance so as to present them before any clowns that are appropriating the current scene, by uttering hollow words that have been said again and again.

Of course, I wish the same to me…

Happy New Year to all!


I just saw this video on Facebook: https://www.facebook.com/TheIndependentOnline/videos/10155437888846636/

I am not absolutely sure how much of it is a genuine conversation between the human and the robot, and how much of it has been fashioned deliberately i.e. as if it were a film with a script.

Having said that, I find it horrifying. This is not only because of the risk of a “Planet of the Robots” becoming true, but also because I see an issue that is far worse and perhaps a lot closer to being manifested: The issue is that, by means of these spectacular advances in getting machines to simulate human thought and responses, humans are going to be drawn into identifying with these inventions. They will quickly get to the point of regarding them as fellow humans. And that is a downright fallacy.

I am a Software Engineer by profession with 28 years of experience in the field of software design and programming. I would never trade the warmth of a real friendship with a real human being for a relationship with a machine, such as Sophia.

We need to ask ourselves whether we really want to do this. Machines are good for their purposes: a phone, a laptop, a GPS etc. But they are not good for absolutely everything in life. Fire in the kitchen is good, because we can use it to cook our food. However, when it ravages a forest, then it is not good.


Sometimes, commas can very important and their presence or absence can make a huge difference in meaning (and effect).

1. His mind was occupied with other, internal goals.
2. His mind was occupied with other internal goals.

1 means that the goals with which his mind was occupied were different from those that one might expect; also, such goals were of an internal nature, not of an external one.
2 means that his mind was occupied with internal goals, which were different from the internal goals described earlier on and/or occupying someone else’s mind.

Today, 21 April, marks the 50th anniversary since a group of military officers seized power in Greece and enforced a dictatorship, which was to rule the country for the next 7 years.

The coup d’etat took place in the early hours of that very day. I was only two years old then, so naturally I have no memory of the event. However, my father used to tell me how he heard the rolling sound made by one of the armoured tanks that were deployed in the night and wondered why on earth were there road works being carried out at 2 in the morning…

The next day, of course, the truth gradually became apparent: The radio was continuously broadcasting patriotic military themes, a tank was stationed at a road junction near our house and then the announcements came: that the army had taken over the governing of the country due to the unstable situation that had developed.

Let’s hope it never ever happens again. Even though an objective historian might – just might – be able to discern a certain degree of good brought about by the dictatorship, particularly in light of the instability in Greece’s political life at the time, such a form of rule can never be a healthy substitute for Democracy.

This is really very well-written and worth reading!

My Comic Relief

So…it’s been a week huh?  I was planning on writing a fun post about how much I’m loving The Totally Awesome Hulk today but I can’t get my head around it.  Reading the news for the last five days has taken me on an emotional journey.  I’ve been spending much time in thought and conversation with loved ones about where our country is heading.  I’ve been struggling to understand, let alone find my place in the events that are unfolding.  As I do this, I keep thinking of something Bruce Springsteen said during a concert in Western Australia last Sunday.

On its own, I found Rogue One to be very enjoyable and superbly made. There’s every good praise to be made for its story line, effects and artistic direction.

The basic problem about it – and I think that this is what might generate some reservations among fans – is that the story has very little to do with the essential, central Star Wars story line, which we have come to know as being the downfall and redemption of Anakin Skywalker. Of course, the film absolves itself of this fault by including the phrase A Star Wars Story in its title. This subtitle doesn’t appear on screen, but is part of the film’s official title. So, I think one needs to take the subtitle literally and make an effort to get over the fact that this is not a Skywalker story.

Beware of spoilers from this point onwards, if you have not yet seen Rogue One.

Despite what I said above, Rogue One does center again on a family broken apart by the evil Empire’s plans, much like what happens in the seven episodes of Star Wars. This time round, however, the reason for the breakup is less spiritual, less esoteric than the corresponding events in the Skywalker timeline.

Thumbs Up and Novelties

Well, at last, we see the true scale of an Imperial Cruiser as it hovers above the city of Jedha. I had been wanting to see something like that. (The same goes for TIE fighters and The Force Awakens was the first Star Wars film where we see TIE fighters next to their human pilots.)

The spectacular aerial battle in the rain on Eadu rivals the battle over the lake in The Force Awakens. However, the latter is still my favourite.

The other spectacular battle over Scarif harks back to the one over Endor in Return of the Jedi and I was very happy to hear the various squadron leaders reporting in just before it ensued, this particular detail being reminiscent of the future attack on the Death Star in A New Hope (only a film away!). Oh, and I did enjoy that scene with the Hammerhead Corvette causing those two Star Destroyers to crash!

The ground battle on Scarif was, of course, very impressive and kudos for the beautiful scene of Chirrut’s slow advance forward towards the communications master switch before being shot. It was saddening to watch the heroes falling one by one.

The final scene, when Tarkin orders the destruction of the base, shows the full ruthlessness of the Empire and its indifference even to the lives of its own officers. This is perfectly embodied by Tarkin himself.

And the film leads very nicely to the point where the events of A New Hope will begin, with Tantive IV leaving the scene of the battle and carrying the plans of the Death Star.

How ironic that Galen Erso used the same pet name for the Death Star project and his little girl, knowing that Jyn would thus be able to identify the stored plans when she came across that very name. The irony is carried even further when you realise that the Death Star’s primary function is to destroy planets and reduce them to… stardust.

There is also another interesting irony: The Jedi use the Kaiburr crystals for their lightsabers while the Empire uses them to destroy planets.

Interestingly enough, Rogue One is the first Star Wars film where the names of planets are given on screen. I noticed, however, that no such names were given for Jyn Erso’s home planet and the one where Orson Krennic visited Darth Vader.

Nods and Cameos 

I first saw the name Kaiburr ages ago in Alan Dean Foster’s novel Splinter of the Mind’s Eye.

Chirrut and Baze are described as being “Guardians of the Whills”. I believe the name “Whills” comes from the very first novelisation of Star Wars by George Lucas himself, back in 1977. The prologue to that briefly describes the downfall of the Old Republic and the seizing of power by the “ambitious Senator Palpatine”. Underneath the prologue is the phrase:

From the First Saga
Journal of the Whills

I noticed Dr. Evazan running into Jyn and Cassian in the streets of Jedha. And, then, there was the proverbial chess game being played outside the cell where Cassian, Chirrut, Baze and Bodhi were being held, as well as a Twi’lek dancing.

I smiled when I heard K-2SO nearly phrasing “I’ve got a bad feeling about this”!

Darth Vader

Oh dear! Darth Vader was probably shown at his meanest ever when he butchered all those poor Rebels in one of the last scenes.

Prior to seeing the film, I had predicted that we would see Vader force-choking Krennic to death, but then I thought that that would have been due to Krennic’s inability to stop the Rebels from stealing the Death Star plans. Well, I only got it half-right, since the choking was for another reason and not fatal.

Krennic eventually met his bitter end, brought about by the very machine that he was so proud of…

I noticed Vader’s voice to be somewhat aged in relation to the one in Episodes 4-6, but there’s no escaping reality: It has been 11 years since Revenge of the Sith was released.

Grand Moff Tarkin

Well, that was a surprise. They did a really good job creating a digital image of Moff Tarkin to superimpose on the real actor who portrayed him. You could tell it wasn’t really Peter Cushing, but the resemblance was really very good and I must admit that – while watching the film – I kept wondering “Is it CG?”, “Is it CG?”.

Princess Leia

I was even more surprised to see her! I was sure there wasn’t any chance of seeing the Princess, just the departure of Tantive IV from the battle scene. I am glad to have been proved wrong. You could tell that she was CG, but it didn’t matter.

Missing Scenes

I could not help noticing that some scenes, which I had got used to seeing in the trailers, didn’t make it to the final cut. Most notable of these was the one where a TIE fighter confronts Jyn Erso on that platform where she had gone to transmit the plans up to the Rebel fleet. I was waiting to see that TIE fighter, but it never appeared. What happened?

And then, I never remember seeing Mon Mothma talking about the Empire’s upcoming “weapons test”, or Orson Krennic saying “the power we are dealing with here is immeasurable”.

I am not sure, but did they also miss out a scene with Cassian and Jyn running on the ground on Scarif with Jyn holding the disk with the Death Star plans?


Rogue One is a Star Wars story indeed, well worth seeing. Here’s to many more!

Do you remember that famous carol “The Twelve Days of Christmas”? You can find some historical information about it at Wikipedia. There is also a section on its financial implications.

What I find interesting about this carol, from a mathematical point of view, is the structure of the underlying collection of gifts as well as the calculation of their total number.

The carol starts with a seemingly innocent gift of a partridge in a pear tree sent on the first day of Christmas, which is 25 December. Then, however, as the days proceed through the Christmas period, the gifts received on any one day are:

  • a completely new set of gifts equal in number to the number of the day within Christmas (e.g. on the third day I get three French hens for the first time, on the fourth I get four calling birds for the first time and so on)
  • the whole lot of gifts that were sent on the preceding day

This process, where the set of gifts on any one day is linked directly to the gifts of the preceding day, is an example of a concept known as recursion. Recursion is widely used in both Mathematics and Computer Programming. Many interesting books have been written, which address this concept. If you have ever come across those beautiful images known as fractals, then I should tell you that recursion plays a great part in their production.

Let me turn to the second reason for my interest in the carol: How do I calculate the total number of gifts received from my true love?

Well, if you examine its verses, you will see that I get:

  • 1 partridge in a pear tree on each of the 12 days of Christmas, hence 1 × 12 partridges in their pear trees
  • 2 turtle-doves on each of the last 11 days, hence 2 × 11 turtle-doves
  • 3 french hens on each of the last 10 days, hence 3 × 10 french hens
  • 4 calling birds on each of the last 9 days, hence 4 × 9 calling birds
  • 5 golden rings on each of the last 8 days, hence 5 × 8 golden rings
  • 6 geese a-laying on each of the last 7 days, hence 6 × 7 geese
  • 7 swans a-swimming on each of the last 6 days, hence 7 × 6 swans
  • 8 maids a-milking on each of the last 5 days, hence 8 × 5 maids
  • 9 ladies dancing on each of the last 4 days, hence 9 × 4 ladies
  • 10 lords a-leaping on each of the last 3 days, hence 10 × 3 lords
  • 11 pipers piping on each of the last 2 days, hence 11 × 2 pipers
  • 12 drummers drumming on the final day, hence 12 × 1 drummers

Phew! That’s the whole lot… So, the total number of gifts is the sum of all the above, namely:

(1 × 12) + (2 × 11) + (3 × 10) + (4 × 9) + (5 × 8) + (6 × 7) +

(7 × 6) + (8 × 5) + (9 × 4) + (10 × 3) + (11 × 2) + (12 × 1)

Now, the individual products of the first line are all repeated once on the second line, so this sum is actually twice the value of the first line i.e.

2 × ((1 × 12) + (2 × 11) + (3 × 10) + (4 × 9) + (5 × 8) + (6 × 7))


2 × (12 + 22 + 30 + 36 + 40 + 42)

or by doing the sum in brackets

2 × 182

and finally 364.

Now, isn’t that strange? Because the total we have arrived at is precisely one less than the number of days in a year (forgetting leap-years). So, by sending me all these gifts and with the proviso that I resort to one gift per day, my true love has taken care of me for all but one of the days making up one whole year beginning on Christmas Day. These gifts will take me up to the day before next Christmas Eve. That Christmas Eve there will be no gift to use as it will be the 365th day. I should then spend that day thanking my true love and anticipating the flurry of gifts, which will follow on the next day, if she still has the means!

I cannot help wondering whether the creators of this carol designed it on purpose so that the total would come out to 364 or whether this fact completely escaped them. In any case, it is an interesting calculation.

Thank you for bearing with me. May you have a Merry Christmas and a Happy New Year!
