+ Everything in the human life is directly related to
+ information. Our actions are based on the information we have.
+ The information is the base of education and evolution. It is
+ the only way we can know how to do the right thing for us and
+ others. I beleive that, in order to provide a good education,
+ the universal information must be accessable to everyone in a
+ transparent way, based on facts and without any manipulation
+ (i.e., in way others can reproduce or verify what the
+ information refers to). That kind of information is good
+ information to based our lives on. However, there are also bad
+ information that we need to differentiate from good
+ information using our own conscience, not that one from
+ others. I like the idea of structuring my life over pragmatic
+ fatcs that I can verify together with a deep faith on what I
+ am that help me to persist along the duty. The pragmatic fatcs
+ provides the steps of the stair of my life and the faith, the
+ force my body needs to climb up the stair.

+ The years I worked for cuban State coincided with those years

+ faith on my movements. Lot of contradictions have been
+ appearing in front of me since then, but a magical thing
+ inside me (conscience) always tell me not to abandon the must
+ pure of my self and keep going with this travel I'm still
+ walking on; even when moving up one step in the stair feels
+ like rasping the skin of my body against a rough wall. I know
+ it will heal, but it hurts when happens. The only way to
+ support the pain is to have faith on the rightness of your
+ actions. That's the price of don't loosing oneself when
+ walking over pragmatic facts in a confussed and unarmed
+ society. That's the price of showing out that truth is inside
+ us, not outside us. It is the way of showing the truth is in
+ the one's faith, no matter what it be, but in feeling it
+ somehow, specially when it comes from understanding what we
+ are and the immense gift it is to have conscience of our
+ univeral existence as part of that unknown nature we, as
+ living humans, cannot ever have conscience of.

+ I've experimented faith in free software and the philosophy
+ behind it, but no possible way to manifest it independently
+ from cuban State. The cuban State controls all the
+ communication media and very few possibilities are available
+ for cubans to build up independent collaborative networks
+ using computers inside the island for sharing information
+ apart from cuban State restrictions and conditions. One of
+ these possibilities is the telepohne network the cuban State
+ provides, which has national scope. Generally, cubans use the
+ telephone network to talk among themselves, but it is also
+ possible to use this network to transmit information that
+ cannot be communicated using the regular method of human
+ talking. It is possible to attach computers to the telephone
+ network the cuban State provides to transmit whatever
+ information a computer can produce (e.g., images, documents,
+ programs, etc.) from one location in the island to another and
+ encrypting the information traveling along the wire to
+ garantee its privacy (e.g., the source computer protects the
+ information in a way that only the target computer is able to
+ unprotect. If the information is intercepted by a computer in
+ the transmission middle, it would be useless for that computer
+ since only the target can unprotect it). We'll see more about
