Wikileaks - Bin Laden and a Texas court
The first is a clear-cut case of good versus bad: innocent people are convicted by criminals who occupy chief positions in the court and the police . Example: a person convicted of drug traffic has in fact never trafficked drugs while the policemen that indicted her on false evidence are in fact drug dealers. Well this is what is described in this apparently accurate book! Is it true? I'm not entirely sure, but, if it is, it is a clear case of good guys vs bad guys.
Now, what makes this so clear to us is a set of shared beliefs about what constitutes good and evil. Inflicting a punishment on someone for an action that he or her did not commit is, we all believe, something evil. And when someone gets away with something (such a dealing drugs) that is correctly prohibited, we also generally believe this to be wrong.
Now in the case of the jihad that Bin Laden and others proposed in 1996, we are looking at very different sets of assumptions which are not shared by the different cultures that have to share this region (Muslims, Jews, Christians, Scientists / Atheists). Not only about what to dress, but how to behave, values, who to obey, what to obey, and why to obey. When I read Bin Laden's words I can't stop feeling a great compassion towards him, I do understand his pain and the ways he has available to deal with it. Basically he is saying that the bads that have occurred to Muslims all over the world are due to the fact that they had been to permissive regarding their involvement with the sinfulness of rest of the world. "Infidels" should not have influence in "holy" lands. Well... you can't really reason with someone like that.
When I knew that Bin Laden's texts were on the net I thought, great, now I will see the other side, but seeing it made it very clear that there is really no way of communicating (communion) with someone like that. If I am an infidel and he is a saint, well, what can an infidel say to a saint? What can he possibly bring except disgrace, sin, shame, etc. Bin Laden's position is like an Iron Wall made of feelings of what is proper and useful and what should be neglected and dispised. All that are on the outside of the Muslim faith must be despised, all that are inside must try to remain pure.
Only in this context of "remaining pure" does it make sense to talk about the military, economic and political issues also at stake. Ironically, the recent military interventions by the US on the Middle East will indeed provide an excellent background where the ideas of these crazy radicals can flourish. I am not saying that the military, political and economical issues are not real. Governments in the Middle East are indeed corrupt, and there are many issues between the arabs and israelis, including the lands taken in the aftermath of the 1948 war. But this kind of problems also exists in Europe and many other parts of the world. What makes the situation almost impossible to solve here is the disregard for the other side. The hard line of both Jew and Muslim orthodoxy (along with most Western religions) consider themselves superior and, the Jews at least, entitled to reign over the other tribes of Israel. As long as this craziness from religious fanatics continue there will be no other choice but to let them all kill one another until only reasonable people are left. These, I think are the people that don't alienate themselves with images or notions of God that they themselves have created as a group. The God that we were able to create is, by far, very different from the God who would be able to create us.
Let me just reinforce the idea: I've read Chomsky and I understand that colonialism just changes it's appearance. But the question here is how we deal with the influences of other countries and cultures. If there is no communication, and instead just despise and disgust and the attempt to "remain pure"... well, what can you expect?
There are here two different problems, the first is that this region has resources that have high economical value to western societies. This leads to heavy interference in the region based not on a human interest (in the art or human qualities of a people for instance), but on exploitation of resources, which leaves indigenous people rightly mad. The second problem is that some of these Muslim guys do not want contact with the outside world. Even if there was no exploitation, it wouldn't matter. It's our own way of life, we are disbelievers and non-obedient. We praise difference, diversity, authenticity. We are certainly infidels.
Conversely guys like Bin Laden are quite happy in their frame of mind of "obedience to God and the scriptures". They are happy if they can spend most of their day praying to God and trying to clean themselves. They don't care about pornography, expensive clothes and lipstick; they don't want to know about science and galaxies and dinosaurs, they just want to live by the words of the prophet. We should just let them be... just let them be... Let them stay with their lives, they wont search for weapons of mass destruction, they'll just... well, persecute the infidels among them and the infidel inside them... they'll be quite happy that way.
But of course... we can't, because of oil... We are joining a 21st century society, which fuels its high technology with something that can be found in a civilization similar to ours more than four centuries ago. It just wont work... There are just two options, either an increase in military operations until one of the sides decisively wins, or some other form of energy is found that completely replaces oil turning it into something with no value at all.

Wikileaks
http://www.wikileaks.org/
(based in Sweden and has nothing to do with wikipedia, which, by the way, is becoming more and more controlled - just watch out the "overpopulation" article!!)
18 years working with computers
The decision to buy an AMD cpu had to do with price but it rapidly become a matter of principle. For years I would accompany the highs and lows of Cyrix and AMD always hoping that their technological prowess (especially by Cyrix) would finally translate into a significant market share; I was incredible disappointed when Cyrix was bought over and literally destroyed. For me Intel represented the "bad guys", the monopoly, the high price and low productivity, the closed market, sacrificing global evolution to get selfish profits, etc.
From 1997 onwards things have slowly changed and, today, I don't think there is much of a difference between most brands in the way they deal with costumers. The first impact on my understanding of AMD was when they blocked the clock of CPU's that were being artificially underclocked, that is, a good product was being changed into a lesser product just to create different categories and higher prices for "luxury" products. More recently I made the mistake of buying a laptop with an Intel Celeron cpu, to realize only later that this kind cpu has its energy saving parts burned of at the factory so other cpus can be sold more expensively. Intel, of course, as not only created chagrin for the customer but also another cross for the environment. But the style was the same for both companies. ATI also had been making a gigantic effort to make lesser products investing large sums of money to make sure no one could transform their artificial downgraded products into their full version originals (remember the radeon 9500 and its bios' hacks). This for me was a clear sign that AMD, Intel, ATI and many other companies had made profit their highest goal, rather than helping technological evolution, building a better world or simply respecting the people that buy their products. It was therefore without surprise that I've learned that several motherboard makers had use faulty capacitors to provide for planned obsolescence of their products, a practice that continues today. The perfect plan would be for a product to fail right after the guarantee expires. Perhaps we'll get there!
AMD and Intel are like Yahoo and MS Search engines. Their main concern is with profit. Yahoo did not want Google's engine when it was offered to them because their main interest is to get us to see their links, their paid links! Why would they make links accessible if they do not pay anything to them? It may seem absurd, to provide good information for free disregarding the ones who actually pay us, but that absurdity is what Google did! It put consumers first, and look how that craziness got them!
But, obviously there is no Google-like company on the CPU front. Another example is this: I have a relatively outdated desktop PC, which runs pretty well in my daily needs. It has 2 gb of ram, a +3000 cpu, a 2400 pro radeon graphics card and the motherboard can be highly overclocked. All well and dandy. But sometimes I would really like to have more cpu power, so, well I thought about upgrading the cpu. Well, surprise, surprise, since my current motherboard uses an old 939 socket, AMD is selling outdated cpus for more than 150 euros, something that would cost only about 60 euros for the most recent AM2 socket.
So I am given the following choice, either pay a huge amount for an outdated CPU or buy a whole new system (ram memory and motherboard are not compatible). Economically the rational choice would be to buy a new system and put everything in the trash bin, but that has a huge environmental cost. So I decided to just stay with the current system. I know people who are happy with their ten year old PC's running windows xp on a 198MB ram machine, reading and writing and surfing the web. If it works great why change it? If you just write and browse and listen to music and see movies, etc, then nothing else is needed. Perhaps you'd just like to get Vista? Wow, well we are actually thinking about getting rid of vista in the new laptop we bought, so that can't be it. XP is by far a better OS, as are many Linux distros. Vista is a huge drawback! So, although as a teenager I've wasted almost all of the money I gained working in the summer vacations by buying new motherboards, cpus, CD-ROMs, and ram memory, now, it seems to me that to be computer-wise is simply to maintain the current hardware (until the capacitors fail !!) and look for better software, which means, software that makes a better use of current resources. This means most of the time going for free software like oppenoffice.org, irfanview, etc.
For more processor demanding tasks, we'll just have to wait for software that uses the new GPGPUs out there (my lowly 2400 pro included). They are the new technological equivalent to the Cyrix mathematical co-processor I had 17 years ago. I've only used it in a short attempt to keep up with folding@home deadlines, but it was fun to see this 30 euro graphics card performing better that any top of the line cpu. That is certainly the future as most intensive applications can use mass parallel processing, from artificial intelligence to converting audio and video.
It's time to slow down on the hardware and investigate the software more and more... GPL here we come!
PS - have been thinking that the main reason for "the hardware is dead, long live the software" is probably due to the stagnation in software development. In the last five years mainstream software, with the exception of games, has known no real advances. Microsoft Office and Windows OS have reached their peak in 2003, all there has been since are small cosmetic differences, sometimes arguably for the worse. On the side of free software, by the contrary, there has been a steady evolution. But the new hardware (mainly GPGPUs) could have been used by Artificial Intelligence software. Somehow the investment did not went into this sphere, perhaps through games AI will grow. More and more we live to be entertained which might actually be a good sign, provided it's not alienating.

Evan Almighty - from slave of images to slave of... well, concepts...
The movie starts by depicting a way of life in which one is a slave to pleasing others, image is all that matters. The "metroman" the congressman, the vip. To have success you must seem successful, and powerful, handsome and happy. The perfect life that leads you to... being a slave.
It then goes on to another side of life in which you try to do things not because you are a slave to what you think others might think of you, but because...
Well, here is where the confusion starts, whereas in the "Bruce Almighty" everything followed plausibly once you accepted you had absolute power, here we are at a loss. First of all the premise is quite obscure. An all powerful, omniscient and loving God asks for someone to do an ark without giving any explanation. Why does God do that? Is psychology remains a mystery. In the film it is said by God himself that the story of the ark is a love story, of believing, of trust. Well, ok, so instead of being a slave to the image that other's might have of me, I'm slave to God.
What's the difference, well, in the movie, the difference is that you gain others' amazement at your abilities. You ty to do something that is almost impossible, completely illogical, and you achieve it! Animals obey to you, you predict the weather with incredible precision and so forth. You became a star all over the nation.
This shows the shallowness of the message, people are not released of their desire to be accepted by others. In fact it is the same desire for fame, only the strategy to get it changes.
Of course, there are differences, the dramatic change in outllok is accompanied by a change in eye gaze, posture, way of speaking and interacting. What changed was the master, because he is no longer a slave to physical persons but to an abstract entity, he can now be more detached. When his family finally reapers to be "side by side" he looks a sea of tranquility in which a few drops have touched. Why? Because his stewardship remains elsewhere. He seems free but he did not become free. He traded one slavery for another, just to get more profits.
This is our hero, completely at loss, but God seems equally at loss here. What exactly is he trying to do? Well, supposedly He is giving an opportunity, for us to achieve whatever we want to achieve. If we want to be courageous God give us a chance to show our courage, if we want to change the world God gives us a chance to change the world. Well what if I want to play baseball on the moon? I mean, is this the way we imagine the world to be like? I always thought things were much more complex, an interrelation of stories into which we are mysteriously attracted.
The sequence of events is of course completely implausible, unless you think the Bible is a plausible book! And even if we take them as metaphors for something much more subtle it is difficult to imagine something different from a paranoid life in which everything seems to revolve around us!
The word "ark", in the end of the film is associated with "act of random kindness", which is in fact something quite beautiful. But seeing signs of things that must be done, the difficulty in recognizing, in front of everyone that "I" speak with God and he replies etc, all these things seem to inhabit the life of some obsession.
For instance, when we say that we are inspired by beauty, by ideals of freedom, by music, by nature, etc, this inspiration is not something that puts us into chains. It is something that release us. Inspiration is not a prison, a collar, a chain, it is a trampoline, and when you take it, there is a large part of you that has to decide where to take that energy, what to make of the jump, where to land, etc. Things are given to us and obviously we should appreciate them well, but the idea that we have a mission is the root of identity and identification, of all suffering, of having a way and a cross and something to bear. All suffering springs from that desire to be special, different, unique, worthy... But when we look at the stars, at flowers and rivers, we see something quite different. The beauty of Beethoven's music has no bonds, it is limited in the sense that it expresses only a small part of reality, but the beauty of it cannot be tamed, cannot be understood, specified, limited in an explanation, a place, a time. If we were able to see that we are not special in any way, that we are like the Beauty of Beethoven's music, a prairie, a river, etc., we would see at the same time that we have a beauty far beyond what we usually imagine or even that which we attribute to God.
In the movie dogs and elephants were just animals. They were not among the "children of God". In fact got only had the billions of men and women on this planet. All other extraplanetary civilizations simply have no place in God's lap. Animals obey God, people are free. This divide in which man is supperior and has to take care of animals, has to be kind, is somewhat beautiful but it is a pale beauty when our eyes are unclouded and we see that there is no need to "change the world", the world is well beyond whatever we could imagine in our wildest dreams.
However one can easily see where the magic of this movie is: when we follow what we feel is important, what is "commanded from God", what comes from above, even if we can't quite explain why it is important to ourselves. In that "obedience" or listening, there comes a pleasure, a quite different kind of "success", not external but internal. You might loose your job, reputation, even your family, but you will gain the most important thing, you did what was right, you were successful in the only way that is truly meaning and satisfying.
In showing this "happiness" the movie works quite well, it seems to me very appropriated that the movie's end credits are accompanied with "dancing", the expression of this well being that results from a person doing what he /she as to do.

Bruce Schneier - interesting site and interview
Here is a copy of the interview (these things have a tendency to get lost)
«Dahna McConnachie speaks with Schneier about his talk, "Reconceptualising Security" and how technologists need to remember the importance of the human element. He also discusses cyber-war, what Linux has done for security, and the likelihood of another edition of Applied Cryptography.
What do you spend most of your spare time working on these days?
Much of my work these days involves the human motivations around security: the economics of security, the psychology of security, and so on. Again and again I see good technology failing because these aspects of the security system haven't been well thought out, and these social science communities have a lot to teach us in computer security.
(Read some of Bruce's recent thoughts on the psychology of security here)
What will your keynote talk "Reconceptualising Security" be about?
Security is both a feeling and a reality, and they're different. You can feel secure, even if you're not. And you can be secure, even if you don't feel it. Really, there are two different concepts sharing the same word. My talk is about the feeling and reality of security: when they are different, why they diverge, and how they can be made to converge. As technologists we tend to focus on the reality of security and ignore the feeling. I will argue that both are important.
Do you think that technologists sometimes forget about the human element generally when designing, developing, testing, implementing and/or maintaining systems?
Sometimes? I think they forget almost all the time.
One of the messages you preach is that organisations need more than secure algorithms to be secure. Can you synthesise this argument, in terms of what it means, particularly in today's Web 2.0 environment?
Security is fundamentally a people problem. It doesn't matter how many bits your encryption algorithm has if your employees go home and blog about your company's secrets.
Analysing the security stories that make the news is one of your pastimes. Is there a disparity between what gets covered and what matters the most?
I think the media covers security stories more or less at random: they cover stories that aren't important, and they miss ones that are important. Largely, this is because the stories can be complicated and technical, and reporters don't have the expertise to separate what's important from what isn't.
You have said that we have not yet seen true cyber war, but that it is not a myth. Does this mean that real cyber war is inevitable?
War is inevitable; we as a species don't know how to resolve large nation-state conflict without it. And any war encompasses all theatres: land, sea, air, and now cyberspace. Any future war will include a cyber component, so by that reasoning cyber war is inevitable. But don't think of it as a separate thing. Cyber war is part of war, and not a substitute for or a precursor to war.
Have most countries developed cyber-war tactics?
Of course not. There are 245 countries on the planet, and most of them aren't doing anything with respect to cyber-war. The large countries with large military budgets are. All of them. They'd be foolish not to.
Where do you think the tension between government's increased desire for information (in the form of data mining and surveillance for example) and public freedom and privacy will lead?
Martin Luther King Jr once said that the arc of history is long, but it bends towards justice. There will always be a tension between a government's desire to control its population and the peoples' desire for liberty. And while governments are winning today, mostly because of the scary bugaboo of terrorism, there's no reason to believe that this will continue. It may take a generation, but the balance will shift and liberty will again be important.
What are some examples of where too much trust has been placed in security products?
We trusted airport security before 9/11, with disastrous results. We trust firewalls, IDSs, encryption, and almost every computer security product, and are continually surprised when they're broken. No security system is perfect; defense in depth is the only reasonable strategy.
What are some of the most significant ways that Linux, open source software, and the free and open software philosophy have contributed to the security landscape?
The most important thing Linux has done to improve security is to be competition for Windows. Monopolies are complacent, and by being an alternative, Linux forces Microsoft to improve its own operating system.
What will be the biggest security issues in the future?
Crime. Crime, crime, crime. Everything else pales in comparison.
What will be the largest cyber-threats to freedom and privacy in the future?
Government. And criminals. Both are large threats, in different ways. The latter is more tactical; the former is more serious and more long term.
At the time that you released Blowfish, most other designs were proprietary, patented and/or kept confidentially by governments. Why did you decide to release Blowfish into the public domain?
If I kept blowfish proprietary, or patented it, it would have died a quiet and lonely death. With few exceptions, proprietary and patented algorithms don't get used by anybody.
A rough count from the list on your Web site indicates that there are well over 150 software products (including the mainline Linux kernel, from v2.5.47) that use Blowfish. Has it exceeded or met your expectations?
I don't know if I had any expectations. There weren't enough alternatives to DES out there. I wrote Blowfish as such an alternative, but I didn't even know if it would survive a year of cryptanalysis. Writing encryption algorithms is hard, and it's always amazing if one you write actually turns out to be secure. At this point, though, I'm amazed it's still being used. If people ask, I recommend Twofish instead.
You recently launched a stinging attack on the elliptic curve-based Dual_EC_DRBG, one of four techniques RNG designs approved by the US National Institute of Standards and Technology (NIST) in March of this year. The controversy surrounds numbers used to define the algorithm's elliptic curve from which RNGs are created, which appear to be derived from a second set of hidden numbers - the so called 'backdoor'. What significance does this have on the outside world?
Minimal. I don't think anyone would use the algorithm anyway, since it's about 1000 times slower than the alternatives for absolutely no relative benefit. But it is in the standard, so felt I needed to warn people against using it.
How widely do you think the design is used?
I have no idea. My guess is that someone, somewhere, is already using it and NIST didn't want to piss them off -- that's why the algorithm is in the standard.
Do random number generators have much security value?
Yes. They're vitally important to most security protocols. If they're broken, the whole thing is broken.
Many people have asked for a third edition of Applied Cryptography. Is this likely to happen, and if so, any time soon?
At this point I have no plans to write a third edition of Applied Cryptography. There are several reasons. The field of cryptography has exploded since I wrote the second edition. There are dozens of new algorithms, protocols, and systems. I would have to cover all of the Internet protocols, all of the new MACs and signature schemes, all of the new analysis techniques. Because Applied Cryptography is designed to be comprehensive, there would be no way for me to edit things down...only include the three most important algorithms, for example. So, I would have no choice but to include everything. This would make the book too large for one binding. And publishers hate multiple volumes. And in any case, I just don't have the time to do all the necessary work.
However, in a way there is now a sequel. Practical Cryptography, by Neils Ferguson and myself, was published this year. It's about cryptography as it is used in real-world systems, about cryptography as an engineering discipline rather than cryptography as a mathematical science.
This is the book we wish we'd had more than a decade ago when we started our cryptographic careers. It collects our combined experiences on how to design cryptographic systems the right way. In some ways, this book is a sequel to Applied Cryptography, but it focuses on very practical problems and on how to build a secure system rather than just design a cryptographic protocol.»
Schneier's site has many interesting articles, one of them talks (badly) about Windows Vista. I agree with Schneier, in fact I was one of the many who downgraded from Vista to XP.
An even more interesting article can be found here, about the US presidential elections of 2006 and it's the almost certain fraudes that were commited in counting the votes cast on electronic voting machines.

Getting cleared up in the mind
"Try and penetrate with our limited means the secrets of nature and you will find that, behind all the discernible concatenations, there remains something subtle, intangible and inexplicable. Veneration for this force beyond anything that we can comprehend is my religion. To that extent I am, in point of fact, religious."
"It is enough for me to contemplate the mystery of conscious life perpetuating itself through all eternity, to reflect upon the marvelous structure of the universe which we dimly perceive, and to try humbly to comprehend an infinitesimal part of the intelligence manifested in nature."
"The most beautiful experience we can have is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. Whoever does not know it and can no longer wonder, no longer marvel, is as good as dead, and his eyes are dimmed."

in my inner depths: God and Lucifer
I feel so full of things I cannot integrate...
When I try to take every superfluous thing away, when I look for a core of certainty, a kind of Cartesian first certainty, all I found is, not so much the "I think therefore I am", which is a very complicated sentence involving difficult to understand concepts such as "existence" or "therefore" or even "think / want (the cogito)". I find something entirely different: that I was loved by my creator, that my life has a meaning, that I have a mission.
But, as soon as this certainty emerges, telling me who I am, another will, to break free, to ignore it, to destroy it, comes over me, and I am clashed by different wills of abiding and refusing. In me I can find the roots of good and evil, of God and Lucifer.
What was first saw as an act of Love, of protection, becomes a prison, for which an incredible desire of escape emerges, and this desire is seen as sin.
The two wills clash, one aims for Encounter, Togetherness, the other for Freedom, Authenticity. The main theme of Burgess' A Clockwork Orange, (no free will without evil) I assume.
Only laughter reconciles them, only the immediate spirit and inspiration, unmeddled my the mind or emotions, without guilt orany conception of shame, only the most pure creative spirit, the most naked will, will be able to conciliate both, to find paradise.
