An Interview With the Nativity Innkeeper

An Interview With the Nativity Innkeeper:

Your name, please.
Ben Cohen.
Occupation?
Retired. I was an innkeeper.
In Bethlehem.
Right.
And in fact it was your inn where Jesus was born.
That’s right. Well, not in the inn itself. Out back.
In the animal shed.
Yeah. I still get a lot of flak for that.
How do you mean?
I mean that people still criticize me for not having room at the inn. They say to me, you couldn’t give a pregnant woman a room? You couldn’t give a room to the woman pregnant with the divine child? Couldn’t even spare a broom closet for the Baby Jesus?
How do you respond to that?
I say, well, look. First off, it wasn’t just me. If you go back you’ll see that every inn was full.
Because of the census.
Census, schmensus. It was the foot races. Bethlehem versus Cana. Also there was a touring theater troupe from Greece. Only appearance in Judea. The city was packed. We had reservations for months.
But Mary was pregnant.
I had three pregnant ladies at the inn that night. One was giving birth when Joe and Mary showed up. She was down the hall, screaming at the top of her lungs, cursing like you wouldn’t believe. Her husband tried to encourage her to push and she kicked him in the groin. Think about that. She’s crowning a baby, and she takes the time to put her foot into her husband’s testicles. So maybe you’ll understand why even if I had a room, I wouldn’t be in a rush to give it up to those two.
But you ended up letting them go out to the animal shed.
That was an accident.
How so?
Joe comes in and asks for a room, and I tell him we’re all out of rooms and have been for months. Foot races. Theater groupies. And such. And he says, come on, please. I’ve got a pregnant lady with me. And I say, you hear that down the hall? I’m full up with pregnant ladies. And he says, this baby is important. And I say, hey, buddy, I don’t care if he’s the Son of God, I don’t have any rooms.
So there’s some irony there.
I guess so. And then he says, look, we’ll take anything. And so I say, as a joke, all right, you can go and sleep with animals if you like. And he says fine and slaps some money on the counter.
He called your bluff.
Yeah. And I say, I was kidding about that. And he says, and my wife’s water just broke in your lobby. What could I do? I pointed him in the direction of the animals.
It’s better than having the baby in the street.
I suppose so, but you know, if the reason they were in Bethlehem was because of the census, then he had family in the area, right? It’s his ancestral home and all that. He can’t say to a cousin, hey, give us a couch? There are some family dynamics going on there that have been conveniently left unexamined, if you ask me.
Joseph had a lot on his mind.
Must have.
So the baby is born, and they place him in the manger.
Which, by the way, I told them not to do.
Why?
Because how unsanitary is that? Do you know what a manger is?
As far as I know, it’s the place you put infant messiahs.
It’s a food trough for animals.
Oh. Interesting.
“Oh, interesting” is right. Let me ask you. So your baby is born, and the first thing you do is put him in an open container filled with grain and covered in oxen drool? Does this seem reasonable to you?
You did have them out with the animals. Their options were limited.
I rented cribs. I asked Joseph, do you want a crib. And he said, no, we’re fine, and then sets the kid in the food box. And I say to him, you’re new at this, aren’t you.
In his defense, he was.
And then someone says, look, the animals, they are adoring the baby. And I say, adoring, hell. They’re wondering why there’s a baby in their food.
On the other hand, the image of the Baby Jesus in the manger is a classic one.
Yeah, I mention that when people get on my case about not giving Joe and Mary a room. I tell them that having a Christmas carol called “Away in a Hotel Room” doesn’t have quite the same ring to it. They never have anything to say to that.
It’s said that a star appeared on the night when Jesus was born. Did you see it?
No. I was too busy trying to convince Joseph to rent a crib.
It’s said it was bright enough to lead the Three Wise Men to your inn.
Well, three men showed up at the inn. I don’t know how wise they were.
How do you mean?
The baby is born, right? And then these guys show up. And they say, we have brought gifts for the child. And I say, that’s nice, what did you bring. And they say, we have brought gold and frankincense and myrrh. And I say, you’ve got to be kidding.
What’s wrong with that?
Let me quote another Christmas song for you. “A child, a child, shivers in the cold, let us bring him silver and gold.” Really? Silver and gold? And not, oh, I don’t know, a blanket? An newborn infant is exhibiting signs of possible hypothermia and your response is to give him cold metal objects? Who ever wrote that song needs a smack upside the head.
You’re saying the gifts were inappropriate.
What’s wrong with diapers? A nice jumper or two? A Baby Bjorn? They were riding around on a donkey, you know. A Baby Bjorn would have come in handy. Have you ever in your life gone to a baby shower where someone says, congratulations on the baby, here’s some perfume. No. Because most people have some sense.
I think the idea is that all the gifts were fit for a king.
Yes, a king who first pooped in my animals’ manger. I would have appreciated a gift of diapers.
Point taken.
And another thing, they brought all these expensive gifts, but do you ever hear about Joe and Mary and Jesus being anything but poor? Or at the very most working class?
Now that you mention it, no.
Exactly. I think what happened is these three guys show up and they say, here are all these expensive gifts we got your baby. Oh and by the way, we happen to know King Herod thinks your baby’s a threat and plans to kill every kid younger than two years of age just to be sure, so you better go. Egypt’s nice this time of year. What? You’re traveling by donkey? Well, then you can’t take all these nice gifts with you. We’ll just hold on to them for now, write us a letter when you get settled and we’ll mail them. And then they never do.
I don’t think there’s scriptural support for that theory.
I’m not saying I have any evidence. All I’m saying is that it makes sense.
After the Three Wise Men, were there other visitors?
Yeah. It got a little crowded. The animal sheds aren’t designed for a large amount of foot traffic. And then that kid showed up with a drum, and I said, all right, fine, we’re done.
The song of that incident suggests the drum went over well.
Let me ask you. You’re a parent, your child has just been born, he’s tired, you’re tired, people won’t leave you alone, and then some delinquent comes by and unloads a snare solo in your baby’s ear. Does this go over well?
Probably not, no.
There you go.
After the birth, did your inn benefit from the notoriety?
Not really. Jesus kind of slipped off everyone’s radar, for, what? Thirty years? Thirty-five?
Something like that.
Right. So there wasn’t much benefit there. I got some mileage out of telling the story about the crazy couple who rented my animal shed, and the visitors, and the drumming, but I mostly told it to friends. Then just as I’m about to retire someone tells me of this hippie preacher in Jerusalem who got in trouble with the Romans. And I say, hey, I think I know that guy. I think he got born in my shed. And then, well. You know what the Romans did to him.
Yes.
Romans, feh. Then I sold the inn to my nephew and retired to Joppa. By the time Jesus became really famous I was out of the game. And then my nephew sold the inn and they put that church there.
The Church of the Nativity.
You been?
I have, yes.
It’s nice. I liked the inn better, of course.
Looking back, would you have done anything differently?
I would have comped Joseph the crib.
That still would have changed the Christmas carol.
I know. But, look. You didn’t have to wash out that manger.

How The Speed of Light Was Measured in 1676

How The Speed of Light Was Measured in 1676:

Orbits of Jupiter and Earth

Roemer measured the speed of light by timing eclipses of Jupiter's moon Io. In this figure, S is the Sun, E1 is the Earth when closest to Jupiter (J1) and E2 is the Earth about six months later, on the opposite side of the Sun from Jupiter (J2). When the Earth is at E2, the light from the Jupiter system has to travel an extra distance represented by the diameter of the Earth's orbit. This causes a delay in the timing of the eclipses. Roemer measured the delay and, knowing approximately the diameter of the Earth's orbit, made the first good estimate of the speed of light. Illustration by Diana Kline.
In 1676, the Danish astronomer Ole Roemer (1644–1710) became the first person to measure the speed of light. Until that time, scientists assumed that the speed of light was either too fast to measure or infinite. The dominant view, vigorously argued by the French philosopher Descartes, favored an infinite speed.
Roemer, working at the Paris Observatory, was not looking for the speed of light when he found it. Instead, he was compiling extensive observations of the orbit of Io, the innermost of the four big satellites of Jupiter discovered by Galileo in 1610. By timing the eclipses of Io by Jupiter, Roemer hoped to determine a more accurate value for the satellite’s orbital period. Such observations had a practical importance in the seventeenth century. Galileo himself had suggested that tables of the orbital motion of Jupiter’s satellites would provide a kind of “clock” in the sky. Navigators and mapmakers anywhere in the world might use this clock to read the absolute time (the standard time at a place of known longitude, like the Paris Observatory). Then, by determining the local solar time, they could calculate their longitude from the time difference. This method of finding longitude eventually turned out to be impractical and was abandoned after the development of accurate seagoing timepieces. But the Io eclipse data unexpectedly solved another important scientific problem—the speed of light.
The orbital period of Io is now known to be 1.769 Earth days. The satellite is eclipsed by Jupiter once every orbit, as seen from the Earth. By timing these eclipses over many years, Roemer noticed something peculiar. The time interval between successive eclipses became steadily shorter as the Earth in its orbit moved toward Jupiter and became steadily longer as the Earth moved away from Jupiter. These differences accumulated. From his data, Roemer estimated that when the Earth was nearest to Jupiter (at E1), eclipses of Io would occur about eleven minutes earlier than predicted based on the average orbital period over many years. And 6.5 months later, when the Earth was farthest from Jupiter (at E2), the eclipses would occur about eleven minutes later than predicted.
Roemer knew that the true orbital period of Io could have nothing to do with the relative positions of the Earth and Jupiter. In a brilliant insight, he realized that the time difference must be due to the finite speed of light. That is, light from the Jupiter system has to travel farther to reach the Earth when the two planets are on opposite sides of the Sun than when they are closer together. Romer estimated that light required twenty-two minutes to cross the diameter of the Earth’s orbit. The speed of light could then be found by dividing the diameter of the Earth’s orbit by the time difference.
The Dutch scientist Christiaan Huygens, who first did the arithmetic, found a value for the speed of light equivalent to 131,000 miles per second. The correct value is 186,000 miles per second. The difference was due to errors in Roemer’s estimate for the maximum time delay (the correct value is 16.7, not 22 minutes), and also to an imprecise knowledge of the Earth’s orbital diameter. More important than the exact answer, however, was the fact that Roemer’s data provided the first quantitative estimate for the speed of light, and it was in the right ballpark.
Roemer returned to Denmark in 1681, where he pursued a distinguished career in both science and government. He designed and built the most accurate astronomical instruments of his time and made extensive observations. He later served as mayor and prefect of police of Copenhagen and ultimately as head of the State Council. Roemer is remembered today of course not for his high political office but for being the first person to measure the speed of light.

The Making Of OpenERP

The Making Of OpenERP:
I needed to change the world. I wanted to ... You know how it is when you are young; you have big dreams, a lot of energy and naïve stupidity. My dream was to lead the enterprise management market with a fully open source software. (I also wanted to get 100 employees before 30 years old with a self-financed company but I failed this one by a few months).
To fuel my motivation, I had to pick someone to fight against. In business, it's like a playground. When you arrive in a new school, if you want to quickly become the leader, you must choose the class bully, the older guy who terrorises small boys, and kick his butt in front of everyone. That was my strategy with SAP, the enterprise software giant.
So, in 2005, I started to develop the TinyERP product, the software that (at least in my mind) would change the enterprise world. While preparing for the "day of the fight" in 2006, I bought the SorrySAP.com domain name. I put it on hold for 6 years, waiting for the right moment to use it. I thought it would take 3 years to deprecate a 77 billion dollars company just because open source is so cool. Sometimes it's better for your self-motivation not to face reality...
To make things happen, I worked hard, very hard. I worked 13 hours a day, 7 days a week, with no vacations for 7 years. I lost friendships and broke up with my girlfriend in the process (fortunately, I found a more valuable wife now. I will explain later why she is worth 1 million EUR :).
Three years later, I discovered you can't change the world if you are "tiny". Especially if the United States is part of this world, where it's better to be a BigERP, rather than a TinyERP. Can you imagine how small you feel in front of Danone's directors asking; "but why should we pay millions of dollars for a tiny software?" So, we renamed TinyERP to OpenERP.
As we worked hard, things started to evolve. We were developing dozens of modules for OpenERP, the open source community was growing and I was even able to pay all employees' salaries at the end of the month without fear (which was a situation I struggled with for 4 years).
In 2010, we had a 100+ employees company selling services on OpenERP and a powerful but ugly product. This is what happens when delivering services to customers distracts you from building an exceptional product.
It was time to do a pivot in the business model.

The Pivot

We wanted to switch from a service company to a software publisher company. This would allow to increase our efforts in our research and development activities. As a result, we changed our business model and decided to stop our services to customers and focus on building a strong partner network and maintenance offer. This would cost money, so I had to raise a few million euros.
After a few months of pitching investors, I got roughly 10 LOI from different VCs. We chosed Sofinnova Partners, the biggest European VC, and Xavier Niel the founder of Iliad, the only company in France funded in the past 10 years to have reached the 1 billion euro valuation.
I signed the LOI. I didn't realize that this contract could have turned me into a homeless person. (I already had a dog, all I needed was to lose a lot of money to become homeless). The fund raising was based on a company valuation but there was a financial mechanism to re-evaluate the company up by 9.8 m€ depending on the turnover of the next 4 years. I should have received warrants convertible into shares if we achieved the turnover targeted in the business plan.
The night before receiving the warrants in front of the notary, my wife checked the contracts. She asked me what would be the taxation on these warrants. I rang the lawyer and guess what? Belgium is probably the only country in the world where you have to pay taxes on warrants when you receive them, even if you never reach the conditions to convert them into shares. If I had accepted these warrants, I would have had to pay a 12.5% tax on 9.8 m€; resulting in a tax of 1.2m€ to pay in 18 months! So, my wife is worth 1.2 million EUR. I would have ended up a homeless person without her, as I still did not have a salary at that time.
We changed the deal and I got the 3 million EUR. It allowed me to recruit a rocking management team.

Being a mature company

With this money in our bank account, we boosted two departments: R&D and Sales. We burned two million EUR in 18 months, mostly in salaries. The company started to grow even faster. We developed a partner network of 500 partners in 100 countries and we started to sign contracts with 6 zeros.
Then, things became different. You know, tedious things like handling human resources, board meetings, dealing with big customer contracts, traveling to launch international subsidiaries. We did boring stuff like budgets, career paths, management meetings, etc.
2011 was a complex year. We did not meet our expectations: we only achieved 70% of the forecasted sales budget. Our management meetings were tense. We under performed. We were not satisfied with ourselves. We had a constant feeling that we missed something. It's a strange feeling to build extraordinary things but to not be proud of ourselves.
But one day, someone (I don't remember who, I have a goldfish memory) made a graph of the monthly turnover of the past 2 years. It was like waking up from a nighmare. In fact, it was not that bad, we had multiplied by 10 the monthly turnover over the span of roughly two years! This is when we understood that OpenERP is a marathon, not a sprint. Only 100% growth a year is ok... if you can keep the rhythm for several years.
 
OpenERP Monthly Turnover
As usual, I should have listened to my wife. She is way more lucid than I am. Every week I complained to her "it's not good enough, we should grow faster, what am I missing?" and she used to reply; "But you already are the fastest growing company in Belgium!". (Deloitte awarded us as the fastest growing company of Belgium with 1549% growth of the turnover between 2007 and 2011)

Changing the world

Then, the dream started to become reality. We started to get clues that what we did would change the world:
Something is happening... And it's big!
OpenERP 7.0 is about to be released and I know you will be astonished by it.
The official release is planned for the 21th of December. As the Mayas predicted it, this is the end of an age, the old ERP dinosaurs.
It's time to pull out the Ace: the SorrySAP.com domain name that I bought 6 years ago.
Fabien Pinckaers,
OpenERP Founder
