Alba Machine Status


Trying to get pagerank to the Alba's machine status, I like to mention that the beamline 4 is doing their best to start with the commissioning. It's the MSPD on the top left of this machine status and recently we have added the information about its insetion device:


All the 7 beamlines have opened the frontend and they have received their X-rays but this commissioning is ongoing. Some times we go faster than expected, sometimes we have unsolvable problems. But we are doing efforts to be faster than expected.

Next week, the machine will be shutdown to allow us to do some works in side the tunnel.

Galileo's one day (more) delay

I have work in the Galileo's Gstb-dsf project a long time a go. At that time, many times have said that Galileo was about to be launching satellites, but the Giove delays I understand that we should wait. I've been waiting for today during years and I can wait for one day more.

But I don't like to talk about this delays and the big amount of money that they would cost, apart to the cost of the system itself.

Don't wanna forget Glonass (Rusian) and the Compass project (Chinese-European) , but my knowledge is more about GPS and GNSS (Galileo). What's the difference between this two systems? All this satellite systems lives in the medium earth orbit (about 20000km from earth surface), how can they be different? The name says the difference: The Gps is a positioning system, and Galileo is made for navigation. Motion is the difference, and this difference is given by precision.

The mathematics behind it are the same in all this systems. But how this precision is given? By the time... Yes, the precision given by the location systems is given by how precise is the clock in the satellite and the information provided in the broadcast of the signal. Part of this signal can be emitted encrypted to only allow to certain users to access to the complete time stamp.

The other difference between gps and galileo is the orientation of the service. Gps is a military project from the US, because of that the main goal of the system is the availability for military applications, and the civilian service is a secondary thing. The precision of the system, then, depends of which type of user you are. But Galileo is civilian from scratch, even this doesn't mean open for every one.

Galileo will have an open access signal, accessible by every one like gps, with some better presision. But there will have some levels more:

  • Commertial: Paying a price, the user will have the right for a controlled access for commercial applications who require more more than the basic, and a warranty on the service.
  • Regulated: Paying another price, it's oriented to high security applications who cannot suffer interruption or distortion due to its security reasons.
Don't be to paranoid, the Regulated is thinking in civil aeronautics. Having the main improvement in the vertical precision and the 99% of availability warranted. I hope emergency location beacon systems will have access to Regulated by default, not having devices to some safety and some better, more expensive.

Update 20111021: liftoff!

starting the beamline commissioning

In the Alba synchotron we are reaching some goals day after day. During this last years we have started up the linac, the booster and, this year, the storage ring. Also, this year, we have opened the frontend in some beamlines. Starting in march with Mistral's beamline, and the first x-ray light in Alba (a bit before in the diagnostics beamline with visible light), we continue opening 4 of the 7 beamlines at the end of May.

Today is the day to start the beamlines commissioning. During the day there are some hour planed to have machine physics and some hours planed to delivery beam to the beamlines:




Step by step, with a low current in the storage, we are opening frontends.
(The machine status is not yet public, like it's usual, we have to be happy with snapshots).


Update @ 20111019:
I don't have an snapshot of the machine status with more frontends open, but it's a thing of opportunity: to be looking on this application in the correct moment.




Update @ 20111024: The machine status can be saw from out side. But not yet searchable from google or the "search" in the cells website.

Money doesn't exist

In the Tang dynasty, something starts changing. Since then the money starts to have another representation: the banknote. This, that have seen as an improvement because the traders doesn't need to carry the weight of the metal pieces. They has been able to travel in the empire with the possibility to exchange the paper into money based on metal. An at that time, the paper had a meaning in precious metal.

From that time to our days many times the "smart" leaders have realize how easy is to print more paper that the precious metal that they have.

The last time that this solution have set is a very big historical event in the richness of the world, it was when the US president Nixon breaks the direct conversion between the dollar and the gold. After that all the meaning of money is that it's something that can be exchanged for goods. It's only based in our trust on its value. At that time, the meaning of money have change.

Even worst, today we have one hack further: the electronic money. Now it's not necessary to have the banknotes in a safe who backup the e-cash. Like with the gold coverage brake, but worst. If previously was easier to print a paper than have a precious metal: have a couple of bits in a computer is even easier.

Why, with today's world crisis, the concept of the money have an even worst meaning? Apart of the problem with the meaning of the money, the concept of the debt is corrupted by the economics engineering. It doesn't have sense when I hear that Greece have cheat in the numbers many years a go helped by banks. The rating agencies are trying to clean their faces saying that now they are doing their task (not having everyone with the "excellent") but not assuming responsibilities in the subprimes and the huge collapse in 2008.

After this brake down in the (north-occidental) world, the IMF, have said to the involved democracies what they have to do. But the ones who applied they medecine are not in the path of solution, but the ones who did the opposite way are improving (iceland). Even that, the orders that this IMF are saying to the countries, for example about the retirement, it doesn't corresponds with what they do to itself.

Even forcing some of the PIGS to make changes on their constitution, Belgium have been in a political crisis on about 480 days without government. During this time their economy has been not enormously affected by the world crisis, far from that, their economy grew during this period of frozen budgets and laws. We may learn from the Belgium "solution".

The ECB also dictate its will to Italy and Spain (at minimum) to have their "service" or "protection". When the ECB is loaning cheap money to the banks, and this banks are loaning countries like Greece with a much bigger interest, the meaning of this institutions are loosing its meaning.

There is money to save and rescue the banks and don't left them abandoned to the markets. This new money can be new circulating money (like print more banknotes) or injecting money in soft credits to the banks (like creating bits of e-cash in a server). This to fix the banks' cheating, doubling money using the fractional reserve. That is, only a fraction of the deposits are "in the safe", there is a part that can be moved by the bank to produce more money. But then this money can be count in different ways, two, three or many times. The same money can be counter by me, by you, maybe by a third.

But the countries are left to its luck in the markets (where this banks play). There is no money for the social politics, we have lived out of our possibilities and we have to reduce the budget. But rescuing banks and paying enormous compensations to fire its executives who fails in its task. It's possible to "print" new e-cash to save the banks (with an inflation risk), but due to this risk this cannot be done for the countries.

But their big numbers are related with the normal people, who live normal lives. When they fail in economics, all of us suffers, but not them. Perhaps, they will have a headache because a crash in the market. But for the normal people this means a problem to eat during all the month. An this is not only headache, is also stomach ache...

In the Madrid's community, there is no money for the education. But the visit of the Catholic pope to this community cost more money than this cut. And this is only the community investment on this act, because many companies have "donate" money to this act in exchange on some fiscal benefits (due to that I have remembered the expulsion of the money-changers of Christ in the temple).

In Catalunya, even that in 2003 the gasoline have add a new tax called "sanitary cent". But further than a cent, it was a percentage corresponding to a cent on that year. Even that in 2008, Brussels say this tax is not legal, our politics refuses to remove it. This tax has been made to pay the sanitary bill, and they say is strictly necessary to avoid other less popular measures like the co-payment (you pay something "symbolic" every time that you visit the doctor). But now, 2011, they still talk about this co-payment and still say they don't have enough money to pay sanity service.

They never have enough! A solution for today is only an excuse. What they say today can be the opposite of what they will say tomorrow.

And in Catalunya there is another example of what I see as this economics engineering swindle. How can be possible that the debt of the Catalan government depends on the "column" where somebody puts the cost of a metro line of the Barcelona's city? This is a cost, an inversion, a money paid to the providers (and probably to be paid to the creditors). It doesn't have sense that the numbers can be "make-up" this level. It's unacceptable that in economics the result is fussy depending on how you did the numbers.

Now Portugal have cut the special payments for Christmas and summer. Back to Catalunya, the region government have said that their executives will not receive their Christmas payment this year. The news said that they will save 1.8M€ and the measure will affect about 350 persons. Easy 1'8M€ / 350px ~ 5000€/px: they are not in the media of salaries. Why there is no consequences to this "executives" when they fail in their task? But my doubt is which will be the workaround to pay them using another "ways"?

In the rescued banks (using "public" money) is even worst: the bank managers receive tones of money to be fired. If I do such a mistake like they did in my job, I'll be fired with out any payment, and probably with a lawsuit.

There are millions of persons unemployed in Spain (and the rest of the PIGS, and in the rest of the world). But locally it looks more like a lockout. Since 2008, many companies have instrumentalized this crisis for a cheapness firing the workers and reduce the salaries of the ones who "survive" to their burn. With this crisis, this country is only making big and deeper the bags of poverty. Making the social fracture much bigger. The ones that have more are have even more, the ones that have something are pushed together with the ones who already didn't have nothing before the crisis.

My conclusion is that the representation of the meaning of the richness has been lost. The hack of the banknotes and the mistake that is print more banknotes that the precious metal in the safe has go one step further: the mistake of generate more e-cash than the banknotes the supports this bits. The central banks are injecting this e-cash to big hole of the multiple-counting made by the banks, making this multi-count real or signed by this authorities (e-cash emission using bank soft credits). And to contain their hyperinflation, they force the final citizen to be push to the poorness cutting the social goodness and the menace of the unemployment.

The unemployed people doesn't have money to exchange for goods, but the ones who still have a jobs doesn't know for how long it is, and doesn't exchange their e-cash. This is what is avoiding an issue of removing the banknotes from the banks. The banks are being saved to maintain the confidence of the people in the e-cash. Because behind the e-cash, there is no banknotes, behind there is no precious metals, behind there is no richness.

Behind the capital and the speculation there is nothing. The production of goods is less productive in this society than generations of hacks to cover mistakes. This society is an imaginary giant made by real feed of mud.

Dennis Ritchie

A few days a go, a Very Important Person in the computers world have died. Even that the news has been talk only about an Important Person, and many people can think the Steve Jobs have made a revolution in computers, Dennis Ritchie, in my opinion, have more important goals to receive the "very" in the vip status.


Without his work on Unix (and previously on Multics) together with Ken Thompson and Brian Kerninghan, the Mac operation system wouldn't be possible. Yes it's true that Mac have had many good ideas on usability, but it has many lines written in C, a high level programming language designed by Ritchie and the contribution, again, of Kerninghan. Almost all the computer scientist have on mind Kernighan&Ritchie, and the ones who doesn't probably have problem.
