Razón, Fe, y Religión

Pienso que es buen momento para salir de este tema.

Aunque a algunos les cueste creerlo, me considero una persona sumamente espiritual (no digo religiosa por las razones que expongo luego).

Tan espiritual soy, que estudio las enseñanzas de todos los sabios y profetas, tengo sumo respeto por sus dioses (o la ausencia de los mismos), y abordo con curiosidad las conversaciones sobre costumbres religiosas.

De las religiones monoteístas he llegado a la conclusión de que Dios nos ha otorgado dos dones para aproximarnos a Él: la razón, y la fe. La razón para encontrar el camino hacia Él, y la fe para creer en que al final si hay un sentido para todo, y que vale la pena recorrerlo.

Ahora, ¿Por qué no religioso? Porque el don de la fe ha sido históricamente usurpado por personas e instituciones que han cambiado su significado al de sumisión y obediencia a ciegas. Es el tipo de fe que ha llevado a marginaciones, abusos, torturas, guerras, esclavismo, y genocidios, y al "si no crees lo que yo creo, eres mi enemigo".

Con la razón que Dios me dio, prefiero comprender que las iglesias y parecidos son instituciones imperfectas creadas por hombres imperfectos, y que ambos se equivocan, se separan del camino, y se corrompen. ¿Permitiría Dios que sacerdotes que hablan "en su nombre" abusaran de niños inocentes? (¿Permitiría Dios la censura?) La respuesta de fe es que NO. La de la razón es que los sacerdotes no son de Dios ni hablan en su nombre; son sólo personas, como uno, que decidieron dedicarse a tiempo completo a asuntos de religión.

Razón y Fe son nuestros dones, y si ocurre alguna vez un juicio final, como el Catolicismo predice, creo que seremos juzgados no por nuestra obediencia a ciegas a personas autonombradas como únicos intermediarios con lo divino, sino por el buen uso que le hayamos dado a nuestros dones.

De corazón, para mis lectores, Sin-Lam-Min.

The Exagon

Since the early days of software development we learned that there were some forces that were determinant for a project's success. We identified the triangle of scope, time, and resources (effort), and used to say to our users: "pick two".

Soon afterwards we understood that those three dimensions were not enough when we found that we could build software that met its scope, was done in time, and reasonably within the estimated effort, but was unusable because it was ridden with bugs and had an unbearable user interface. So we added a fourth dimension to the forces that drive software projects: quality. The typical depiction is a thetraedron because in it every vertex is conected to the other three, but a fully connected graph drawn as a asquare would fit the same purpose. We told our users and customers "pick three", and went on, failing to keep our commitments in about half of all software projects.

What we have found after a couple of decades is twofold. First, that it is never a matter of picking the constraints but of balancing them; agile development, for example, aims for a balance that delivers value earlier, even if it means a longer project and more effort in the end. Second, we found that the four dimensions were not enough, and that we needed to consider two additional dimensions to have a project that converges to closure: architectural design, and project design.

The issue is that it is not possible to build any moderately complex piece of software any way you want. The "best design" may be the one that dooms a project to failure, and a typical per-module process may make a project never ending. Both software design and project design must be flexible and thought out as to accomodate and balance the other forces. The what and the how must be included in the plan. A time-critical project and a quality-critical (or resource -bound) project are totally different beasts, and they must be designed and executed differently.

An example. We all know what an automobile must do functionally, and how much it should cost, more or less. But there are infinite designs to meet the basic requirements, and many strategies to build those designs. Only some of them will be sucessful.

The new criteria add up to the forces that interact and must be balanced to have a succesful software project. They are now: scope, time, resources, architecture, and process. A fully connected exagonical graph.

Still on XP

It's been a while since I last wrote about my plan to migrate from Windows XP to Ubuntu Linux. The plan needed refining, and I needed the time to proceed with the migration. What follows is the transcript from my chalkboard with the current plan.

Repartitioning
The backups and repartitioning were successfully done, and I have read-only access to the remaining Windows partitions.

All of my files are still on the NTFS partitions, but they are well backed up. I'll move them to the Ext3 partitions on a need basis.

I'm reminded that I need to write a Python script to catalogue my backups. I didn't like any of the software out there.

Printing
It works, but the plan is to move the Epson three-in-one to a Windows computer. I'll probably get a new printer that has Linux drivers.

Scanning
I haven't made it work, , but the plan is to move the Epson three-in-one to a Windows computer. Scanning is not a priority for me.

Email
Old email is well backed up. Recent email is also backed up by Google Apps/Gmail. Two of the 12 accounts are not on Google Apps, but one of them is switching, and the other one is well backed up by its administrators.

As to clients, I'll have to learn to live with the GMail interface, and handle the rest with Evolution. I still use my inbox as a task list (even issues from the issue base land there), and

Contacts

They were imported to GMail, and they can be exported from there to VCard format, which almost any contacts software imports.

Just now I needed to find the license and code for Delphi 7, and it was in my GMail contacts, as it was in MS Outlook.

Calendar
It was exported to Google Calendar, with which I can live with. I love the email and SMS notifications.

Web
Firefox works great with every page I visit, thank you, and the Chrome-like skins are fine. The fall-back to a Windows session is still available in case of emergency.

Work
Assume the learning curve with Open Office. Any way, most of what I write these days goes to the Web, a Wiki, or to a PDF.

For graphics, Inkscape seems to be all I need. I've never used Photoshop, and there's Gimp in case I need to do manipulation of graphics.

Photography
Picasa3 runs fine in Ubuntu 9.04/64. I don't need anything else because I don't do much postprocessing these days.

Music
Rythmbox Music Player plays my music fine (I don't care about the files in Windows formats). There have been interruptions in the sound every once in a while, but they may be bacause the music is still on one of the NTFS partitions. The album artwork gets downloaded from I don't know where. Searching works fine.

I still have to test burning a CD to listen to in the car.

Skype
It works.

Teleconferencing
Ekiga works great since the admins opened up the SIP protocol route to my moday telemeetings.

VPN
I haven't been able to make VPN to Windows servers work, but I do very little work in those, and can fall back to a WinXP boot when I need to.

Programming
Python, Java, C++, etc. are solved business with native installations and Eclipse.

The only project that is tied to Windows is TRANUS. I'm testing how things work over the virtualized XP today. Delphi7 works fine, and it does so fast enough. I still need to test the Intel Fortran compiler.

Hardware
Bluetooth is not working, which means that my favorite mouse isn't working either. I'll either have to get a new mouse, or a new bluetooth card/dongle.

My keyboard works fine, but it will get some time to get used to the new US-International layout.

Other
I expected Ubuntu 9.04/64 to be faster, but, by today's standards, my Pentium D is an old machine with too little RAM.

Did I miss anything?

La tecnología en contra del arte

Practiqué esgrima mientras estuve en la universidad, en la primera mitad de los '80, cuando en las competencias tenían que estar varios jueces para decretar justamente los toques. Comencé con florete, que ya era eléctrico, pero en el cual el juez todavía tenía que recitar los movimientos y la técnica para dar el punto. Luego me cambié a sable, para el cual no habían aparatos: solo jueces.

Viendo los juegos olímpicos y los mundiales en la tele y por Internet, me parece que lo que ha hecho la tecnología es desmejorar el arte. Con la regla de los toques dobles, que canta una máquina, los tiradores se dedican a hacer loqueras una vez consiguen una pequeña ventaja en la partida, porque de doble en doble ganan el combate. Atrás quedó el defensa y riposta, y el derecho del que inicia la acción a reclamar el toque.

El esgrima es un arte marcial, y la regla de los dobles toques decretados por una máquina acaba con su esencia: que la muerte espera a quien sólo ataca y no defiende.

Mis dos hijos son esgrimistas (y yo tecnólogo). Espero tener la oportunidad de contribuir a que cambien las reglas (no importa la tecnología), para que vuelva el arte.

A través del espejo

Fotografiar a través de vidrios o cristales es difícil porque dependiendo del ángulo y de la luz ambiental el vidrio se puede tornar en un espejo ante la cámara, y no dejar ver lo que el ojo ve.

Un lente polarizante puede ayudar. Pero no hay nada como estar en el sitio preciso con la luz precisa.
