No totalmente como un comercial, pero como algo que querían compartir con mayor audiencia, colocaron en el partido de este domingo (donde el tiempo para comerciales se cobra realmente caro) el siguiente video.

Interesante enterarse por el Blog de oficial Google de algunos detalles extras y que de hecho es el primero de una serie (en los posteriores utilizan más servicios, como youtube, picassa o maps, sin embargo este, denominado Parisian Love, me logro sacar una tremenda sonrisa y una reflexión de hasta donde utilizamos google en nuestra vida cotidiana.

Por cierto las demás historias, puede ser vistas en Searchhistories por supuesto en Youtube

Computer people are generally fine human beings, but nonetheless they do a lot of inadvertent harm in the ways they "help" other people with their computer problems. Now that we're trying to get everyone on the net, I thought it might be helpful to write down in one place everything I've been taught about how to help people use computers.

First you have to tell yourself some things:

  • Nobody is born knowing this stuff.

  • You've forgotten what it's like to be a beginner.

  • If it's not obvious to them, it's not obvious.

  • A computer is a means to an end. The person you're helping probably cares mostly about the end. This is reasonable.

  • Their knowledge of the computer is grounded in what they can do and see -- "when I do this, it does that". They need to develop a deeper understanding, of course, but this can only happen slowly, and not through abstract theory but through the real, concrete situations they encounter in their work.

  • By the time they ask you for help, they've probably tried several different things. As a result, their computer might be in a strange state. That's not their fault.

  • The best way to learn is through apprenticeship -- that is, by doing some real task together with someone who has skills that you don't have.

  • Your primary goal is not to solve their problem. Your primary goal is to help them become one notch more capable of solving their problem on their own. So it's okay if they take notes.

  • Most user interfaces are terrible. When people make mistakes it's usually the fault of the interface. You've forgotten how many ways you've learned to adapt to bad interfaces. You've forgotten how many things you once assumed that the interface would be able to do for you.

  • Knowledge lives in communities, not individuals. A computer user who's not part of a community of computer users is going to have a harder time of it than one who is.

Having convinced yourself of these things, you are more likely to follow some important rules:

  • Don't take the keyboard. Let them do all the typing, even if it's slower that way, and even if you have to point them to each and every key they need to type. That's the only way they're going to learn from the interaction.

  • Find out what they're really trying to do. Is there another way to go about it?

  • Attend to the symbolism of the interaction. Most especially, try not to tower over them. If at all possible, squat down so your eyes are just below the level of theirs. When they're looking at the computer, look at the computer. When they're looking at you, look back at them.

  • If something is true, show them how they can see it's true.

  • Be aware of how abstract your language is. For example, "Get into the editor" is abstract and "press this key" is concrete. Don't say anything unless you intend for them to understand it. Keep adjusting your language downward towards concrete units until they start to get it, then slowly adjust back up towards greater abstraction so long as they're following you. When formulating a take-home lesson ("when it does this and that, you should check such-and-such"), check once again that you're using language of the right degree of abstraction for this user right now.

  • Whenever they start to blame themselves, blame the computer, no matter how many times it takes, in a calm, authoritative tone of voice. When they get nailed by a false assumption about the computer's behavior, tell them their assumption was reasonable. Tell *yourself* that it was reasonable. It was.

  • Never do something for someone that they are capable of doing for themselves.

  • Don't say "it's in the manual". (You probably knew that.)

Reading The Connected Family, a work of Seymour Papert I found a really touching section about how to help someone to use a computer and just wonder why in the FLOSS world we are totally different about this approach, yes I know the How to ask question the smart way by Eric Raymond but this one is older and gentler to new users... now that I have found the original I will do my own translation for this blog as copying from the book (the Argentinian edition) even when it's fine under the current copyright law (Mexican one) could be misinterpreted, anyway this is a text I want to share with anyone that teach and works with computers (and of course it's one of my citations.)

Leyendo en el twitter

Vi que salio la encuesta de un partido politico sobre la opinion que uno tiene sobre el futuro de los niños y la preferencia sexual de los padres

http://www.pandf.org.mx/quieroopinar/

Ayer también me quede pensando, en todas las encuestas que maneja drupal, phpnuke, phpesp, etc. Es muy complicado manejar números únicos, evitar la repetición los bots y cosas peores, por eso es que en realidad no se toman muy en serio los datos que da una encuesta en web slashdot tiene justo el siguiente disclaimer que me parece excelente This whole thing is wildly inaccurate. Rounding errors, ballot stuffers, dynamic IPs, firewalls. If you're using these numbers to do anything important, you're insane. y yo creo que eso debió de tomarse en cuenta acá.

Peor aún en las dos veces que trate de opinar vi que lo hacia como en dos pasos, bueno ayer no le puse mayor atención, pero me di cuenta que el identificador de que uno habia votado solo se guardaba en una galleta:

Content: valor_de_la_cookie

Ahora no soy un experto en esto pero viendo que hace como tres pasos, me parece que el contenido de las respuestas las envia en un POST que ni va oculto y que hace directamente en el navegador, entonces envia algo como "http://www.pandf.org.mx/quieroopinar/guarda.php?pregunta1=1&pregunta2=1&pregunta3=0" nomas como ejercicio esto lo pase a curl a ver que tal, claro esto no asegura que exista un mecanismo extra de validación (que francamente espero que asi sea)

Como ustedes podrán imaginar esto solo es un ejercicio académico que describe la dificultad de contar con encuestas en línea confiables.
