At its most basic, free software is about helping users gain control of their computers so that they can participate unhindered in the digital conversations of the networks and the Internet.
It's about installing software freely, rather than being dictated to by the manufacturer.
It's about using your computer the way that you want, instead of ceding control to lock-down devices installed by software vendors without permission on your machine.

The opinion, and I share this one, of Bruce Byfield in the article GNU/Linux World Domination for the Wrong Reasons that there is the danger of concentrating on short term goals instead of the long term goals.

"The trouble with talking about monopolies," Peter Brown, the executive director of the Free Software Foundation told me a couple of years ago, "Is that it suggests that, if it wasn't a monopoly, if there was competition among proprietary companies, that would be okay with us. But, no, it wouldn't make it okay from our viewpoint." ...

Seeing GNU/Linux shift from the fringe to the mainstream is exciting, no question. Being part of that shift is even more so. Yet in the rebellious glee of watching the paradigms shifting, we need to consider that acceptance can sometimes come at too high a cost. True, insisting that the ethics that built the operating system share in its success may delay or even halt that same success. Yet if those ethics don't survive, then the success will not be worth having.

Para empezar, he decidido hacer un simple programita que activa el salvapantallas. Dado que gnome-screensaver exporta funciones para manejar ésto a través de DBus, era una buena opción. La verdad es que me ha llevado una hora programarlo a pesar de tener 3 líneas de código, ya que no he encontrado nada en internet donde explique cómo usarlo desde C# y que la API difiere un tanto de la que se usa desde C.

El primer paso, ha sido lanzar la aplicación dbus-viewer, un simple programa que te permite ver lo que se está exportando a través del bus de sesión. Así, podemos obtener los métodos, el path, y demás parámetros que tenemos que pasar a las funciones de DBus.

En segundo término he empezado a imaginar cómo usar las clases y métodos. Lo primero que he hecho es programar un programa sencillo en el que no hay paso de parámetros entre los programas. El código es el siguiente:

using DBus;
namespace pruebaboo
{

class MainClass
{

public static void Main(string[] args)
{

Service srv = DBus.Service.Get (DBus.Bus.GetSessionBus (), "org.gnome.ScreenSaver");
DBus.MethodCall method = new DBus.MethodCall (srv, "/", "org.gnome.ScreenSaver", "Lock");
method.Send ();
method.Dispose ();
DBus.Bus.GetSessionBus ().Flush ();

}

}

}

En la primera línea, se llama al método estático DBus.Service.Get, que permite obtener del bus de sesión especificado en el primer parámetro, el servicio "org.gnome.ScreenSaver". Un servicio es lo que exporta cada aplicación, es decir, cada aplicación tiene asociado un servicio.

En la segunda y tercera líneas se llama a una función remota. La manera de llamar a la función es realizando una nueva instancia de la clase DBus.MethodCall. En el constructor se pasa como parámetros el servicio que hemos adquirido en la primera línea, la ruta o path hasta la interfaz que contiene la función a la que queremos llamar (en éste caso "/"), la interfaz propiamente dicha ("org.gnome.ScreenSaver") y el nombre de la función remota ("Lock"). Una vez hecho ésto, sólo nos queda enviar la llamada a la función a través del bus con la llamada al método Send ().

El tema de la ruta o path y la interfaz puede parecer un poco confuso al principio, pero suponeros que la ruta es una especie de namespace, y que la interfaz es el nombre de la clase o de una interfaz como se conoce en cualquier lenguaje de programación orientado a objetos. En caso de que la interfaz no tenga ruta como en éste caso, deberemos utilizar la raíz.

Las dos últimas líneas sirven para decirle al VM que elimine el objeto method de la memoria y para forzar a que envíe todo lo que tiene el buffer local correspondiente al bus de sesión respectivamente.

He observado que mediante DBus puedes manejar bastantes programas, desde el salvapantallas o Gaim hasta Banshee y Tomboy pasando por Beagle, Epiphany, etc... En la próxima entrega os mostraré cómo pasar parámetros a las métodos remotos.

Que lo disfrutéis.

I think it goes without saying that I'm as happy as a kitten.

You never can get too much sarcasm.

The 100$ laptop consists of:
Linux-based
Dual-mode display—both a full-color, transmissive DVD mode
Second display option that is black and white reflective and sunlight-readable at 3× the resolution.
500MHz processor
128MB of DRAM
500MB of Flash memor [no hard disk]
Four USB ports
Wireless broadband that, among other things, allows them to work as a mesh network; each laptop will be able to talk to its nearest neighbors, creating an ad hoc, local area network
Innovative power (including wind-up)

The MIT professor Nick Negroponte is one of main promoters of the One Laptop Per Child programme (OLPC).

In the News: The OLPC programme in India Scrapped!

HRD rubbishes MIT's laptop scheme for kids

Some excerpts from the toi site follow:
- India must not allow itself to be used for experimentation with children in this area -HRD ministry
- Negroponte had made a presentation on OLPC at Yojna Bhavan on April 7 seeking to sell one million laptops at the rate of $100 per unit for children, the cost to be borne by the government.
- HRD thought the Rs. 4500 million could be better spent on primary and health education.
- There exists a conceptual vacuum in which the scheme is being propagated.
- Implications of computer-based pedagogy for childhood have remained a grey zone of research
- Both physical and psychological effects of children's intensive exposure to the computer implicit in OLPC are worrisome, to say the least

My initial reaction to seeing this article has been one of suprise at the amount of thought process put in by the HRD Ministy and other of actually accepting their discretion. At the very outset, the whole problem looks like a very obvious cheap and effective solution which will help India leapfrog from an agro based society to a knowledge based society.

Why the Scrapping is a Sane Decision

The 100$ laptop is based on some premises which actually dont correspond to the ground situation in India. The major assumptions:

a. Laptop as a commodity increases Adoption and Hence Literacy
New usable laptops for an on the move IT professional or real user are in the range of upwards of $700. Where the average per capita income in India is still US$165, buying a laptop is out of question. Now the question that we will have to ask is "Is the laptop filling the gap for bridging the literacy divide?". Adoption is inevtiable, if the things that are being promised are really kept; but that doesnt in anyway guarantee any of the other corresponding assumptions being made about literacy.

b. Laptop as a Pedagogical Tool
This assumption as yet doesnt have a concrete solid provable document of proof. Let us assume that a student never has to have to buy the laptop as the cost is borne by the government. Being a student of Comp Sci and as well interacting with friends who have _not_ been students of Computer Science, I do understand the uses of Computer Based Pedagogy. Im puzzle not with the assumption that cheaper laptops will increase adoption; but with that assumption that Laptop is a method to tackle illiteracy. Even though a laptop is a great supplement, its role as a relacement for classroom or a very effective notebook for a child is totally questionable.

c. Prohibitive Cost
$100 x 1 million children = $100 million = 450 crores. When our requirement is for more infrastructure, the 450 crore investment in an as yet unproved technology is hardly justified.

d. Filling in the Gap
The $100 laptop as is evident is not filling any gap in the education system of India. What we need to solve the literacy problem in India is simple:
- More classrooms and more teachers
- Less reasons for children to not come/discontinue education viz bad classrooms, bad teachers, costly education(not only in the terms paid but also in terms of money lost by not working), precious time, better shorter term advantages
- More reasons for coming to school and continuing education viz. better amenities at school, great teachers, better food, better future...

The laptop in spite of being a great tool is as yet has to fit in or solve any of the ground realities pointed above.

e. Software for the Laptop
Even though the 100$ laptop looks exhiliarating to be able to solve a great digital divide, the software required to distribute the content digitally over the laptops is still questionable. Just having Linux doesnt solve any/all of our problems. For any tool to penetrate even the deepest reaches in India, either the tool has to be very simple(like a mobile), or it has to have very good localised font support. In this scenario, the problem the laptop sets out to solve are as yet unsolved.

Why the Scrapping is a Bad Idea

Now to the reasons as why scrapping is a bad Idea; not because the of OLPC programme per se; but because of its probable effect on other technologies trying to penetrate into the rural folds. Now for the reasons why this scrapping is a bad idea.

a. Money invested till now as a sunk cost
The HRD ministry for all now has to understand that the money invested hasnt borne the fruits as it had expected to. In that case trying cheap, alternative-technology driven solutions might be of use too. [I myself think that technology can solve this issue even without trying to solve the human issue involved].

b. No Alternative for Costlier Indigenious Solutions [Simputer, Mobile]
For all I know, even though scrapping the laptop is bad, its really an awesome tool for one. Ability to form cheap ad-hoc mesh networks is really a wonderful conceptualization of creating a networked mesh architecture. Compare this with the Simputer [www.amidasimputer.com] which costs upwards of $300 dollars for a simple gadget. I had been recently working on making been trying to see if a simputer can be a very cheap alternative to laptops [Rs. 9000 + Rs. 500 for a USB keyboard], and had been very much disappointed looking at the prohibitive costs, 20K for a full color Simputer. Why go for a micro sized screen plus a big keyboard for 20K when you can as well go for a better powered laptop device for 30K? And why not go for a lappie that costs 4500K???

Why should not the government try out the $100 laptops instead of using a Simputer or a bigger linux workstation? This laptop can definitely be used by a village teacher or a RMP doctor or many other adults as a better record keeping tool. For them it will prove much more handy and useful than to a child.

c. Deadstop for Innovation
A Digital alternative for pedagogy makes teaching interesting and not to speak of, the much more productivity increase for book keeping individuals. When this OLPC programme has been scrapped, the incentive for other high technology similar disruptive solutions have been essentially nullified. Not the best way to go for a 'knowledge society'.

The Solution: Reorient the Vision

a. Make the OLPC and OLPT - One Laptop Per Teacher
b. Scrap log books & other arcane record keeping procedures and adopt the laptop as a better book keeping gadget for on the move rural professionals
c. Digital Kiosks can adopt the 100$ laptop instead of depending on the workstations. The dependance on electircity is effectively neutralized by adopting this laptop.

Nirnimesh, where art thou?

Edit: From the horse's mouth, click here

I wonder how he think the developers can force Linus to accept a code into HIS kernel. Maybe using handguns.
Yes, that would be in character for Stallman.

I have to wonder when someone is going to make his shut up. He has far outlived his usefulness for the FOSS, and today is more like a threat to it. Everytime he opens his mount, people will think FOSS is a joke.

So, here is my plea:

RMS, go back to coding.

Any help completely unequivocally appreciated!
