Summary
——-
The goal of this project was intended to have Eucalyptus cloud to
support ARM images so it allows Debian developers and users to be able
to use such facility for taks such package building, software
development (ie. Android) under a Debian pre-set image,
software testing many others.

What was expected to have at the end is a modified version of Eucalyptus
Cloud that supports ARM images on the first place. To date this goal has
been reached but is not complete, read production-ready. Extensive test
needs to be done. Besides that we have another goal which is to get
Debian community to use this new extended tool.

Project overview
—————-
Eucalyptus is a hybrid cloud computing platform which has a Open Source
(FLOSS) version. It’s targetted to be used for PaaS (Platform as a
Service), IaaS (Infrastructure as a Service) and other ‘distribution’
models. It can be used also for cloud management. Given that it has
implemented the EC2, for computing, and the S3, for storage, API, it’s
compatible with existing public clouds such Amazon EC2. Currently it
supports running i386 and amd64 images or NC (Node Controllers) in
Eucalyptus naming.

Eucalyptus is a complex piece of software. It’s architechture it’s
modular composed by five components. Cloud Controller (CLC), Walrus (W),
Storage Controller (SC), Cluster Controller (CC) and Node Controller
(NC). The first three are written in Java and the remaining are written
in C. Our project modifications was targetted to the NC component,
altough there is a remaining task for hacking the UI to allow setting
the arch of the uploaded NC image instance.

The Node Controller is in charge of setting the proper information for
Eucalyptus to be able to run virtualized images. Eucalyptus uses XEN and
KVM hyphervisor to handle internal virtualization subsystem, and
Libvirt, which is an abstraction of the existing virtualization
libraries, for program interfacing.

Having that in mind we are back to our project. For our project to be
sucessful we had various tasks to do. Beginning with understanding such
complex piece of software, followed by hacking the requiered bits and
later integrate the work so it results in a useful tool. Our approach to
the project was then inline with such description.

The project’s history
———————

I started my participation in GSoC approaching Steffen to discuss about
what was expected, or more accurately, what was in his mind. We
exchanged emails previous to my application and that resulted on my
application being submitted. From the beginning I should tell that I
wasn’t much clear on the ‘final product’ of the project, however we
refined ideas and goals during the weeks following to the official
begining of the project. What was clear for me, after all, is that for
this to ‘see the light’ and gain adoption Eucalyptus code needed to be
dealt with.

Our first task was review ARM image creation from scratch, using the
work done by Aurelien and Dominique in previous GSoC. I’ve managed to
get an updated ARM image running under qemu-system-arm. The issues
presented in the past were almost unexistant now that the versatile
kernel is official. You can see this on my first report.

After that being done and sometimes in parallel my main goal was then understand
the internals of the Eucalyptus software in order to figure out it’s
feasibility, where do we need to extend and how big the task is, we
didn’t knew upfront. From the beginning of the project Steffen was kind
to introduce me to the Eucalyptus developers and that have resulted in a
good outcome for Debian, IMHO, to date.

Understanding Eucalyptus internals was quite a fun task to say the less. As you
can see on the first part of the report Eucalyptus is modularized and
the component I was expected to work with was the NC (Node
Controller). Given that I isolated my work focus, I started to focus on
learning the internals about that component.

Node Controller as described is in charge of ‘talking’ with
virtualization hyphervisors in order to arrange things to run guest
image instances. The module has basically one main component: handler.c,
in charge to talk to the appropiate hyphervisor and there are
‘extensions’ (think of OOP polymorphism but acknoledge it’s plain C)
that interact with KVM or XEN.

I figured that if qemu-kvm is ran in Hyphervisor mode we can manage to
run an ARM image with qemu-system-arm. Given that Eucalyptus has
interaction with KVM hyphervisor in place, this answered the question of
the project’s feasibility. First green light on.
>From this point the scope reduced to interacting with the KVM handler
(node/handler_kvm.c) and extend it to support running an image that is
not amd64 or i386.

NC makes use of libvirt to abstract interaction with Hyphervisors. So,
the next phase was learning about it’s API and figure what’s needed to
be modified next. Libvirt uses a XML file for setting Domain (in
libvirt’s naming) definitions. So, Eucalyptus provides a Perl wrapper to
generate this file on runtime and allow the NC to invoke libvirt’s API
to run the instance. Next task then, was adapt such script to support
ARM arch. The current script is taiolred for amd64 and i383. I worked on
that front and managed to get a script prototype, that can later be
improved and support more arch’s.

Generating an adequate Libvirt’s XML Domain definition file for ARM can
be a heroic task. There are many things to have in mind given the
diversity of the ARM processor and vendors. I focused on the versatile
flavour given that I was going to test the image I built on the first
place and it ran fine under qemu-system-arm.
The Perl script wrapper then was adapted for such configuration and it
can be tested independently by issuing the following command:

$ tools/gen_kvm_libvirt_xml –arch arm

The –arch parameter is what I implemented and it’s intended to be
called from the kvm handler on instance creation. With the extensibility
in mind I’ve created a hash to associate the arch with their
corresponding emulator.

our %arches = (
‘amd64′ => ‘/usr/bin/kvm’,
‘arm’ => ‘/usr/bin/qemu-system-arm’,
);

Added the arch parameter to the GetOptions() function and used
conditions to tell whether the user is looking for a particular arch,
arm in our case. The most important parts to be considered are the
, and entries.

hvm

$local_kvm

There’s also and that require to be tailored for arm.

root=0800

As output the script generates an XML template that can be adapted to
your needs and it could be used and tested with tools like Libvirt’s
virsh. So that, it can be useful independently of Eucalyptus. I managed
to get to this point before the midterm evaluation.

Now that we had the XML wrapper almost done, the next task was to make
the handler call pass the arch as an argument to the script, so the
image is loaded with the proper settings and we are able to run it.

Eucalyptus doesn’t have a arch field for NC’s instances. So, after approaching
Eucalyptus developers, with whom we had already being interacting, I
settled to my proposal of extending the ncInstance struct with an arch
field (util/data.h). The ncInstance_t struct stores the metadata for the
instance being created. It’s used for storing runtime data as well as
network configuration and more. It was indeed the right place to add a
new field. I did so by creating the archId field.
Now I needed to make sure the arch information is stored and later used on the
libvirt’s call.

typedef struct ncInstance_t {
char instanceId[CHAR_BUFFER_SIZE];
char imageId[CHAR_BUFFER_SIZE];
char imageURL[CHAR_BUFFER_SIZE];
char kernelId[CHAR_BUFFER_SIZE];
char kernelURL[CHAR_BUFFER_SIZE];
char ramdiskId[CHAR_BUFFER_SIZE];
char ramdiskURL[CHAR_BUFFER_SIZE];
char reservationId[CHAR_BUFFER_SIZE];
char userId[CHAR_BUFFER_SIZE];
char archId[CHAR_BUFFER_SIZE];
int retries;

/* state as reported to CC & CLC */
char stateName[CHAR_BUFFER_SIZE]; /* as string */
int stateCode; /* as int */

/* state as NC thinks of it */
instance_states state;

char keyName[CHAR_BUFFER_SIZE*4];
char privateDnsName[CHAR_BUFFER_SIZE];
char dnsName[CHAR_BUFFER_SIZE];
int launchTime; // timestamp of RunInstances request arrival
int bootTime; // timestamp of STAGING->BOOTING transition
int terminationTime; // timestamp of when resources are released (->TEARDOWN transition)

virtualMachine params;
netConfig ncnet;
pthread_t tcb;

/* passed into NC via runInstances for safekeeping */
char userData[CHAR_BUFFER_SIZE*10];
char launchIndex[CHAR_BUFFER_SIZE];
char groupNames[EUCA_MAX_GROUPS][CHAR_BUFFER_SIZE];
int groupNamesSize;

/* updated by NC upon Attach/DetachVolume */
ncVolume volumes[EUCA_MAX_VOLUMES];
int volumesSize;
} ncInstance;

With that in place what was left was modifying the functions that
store/update the ncInstance data, and also the libvirt’s function that
calls the gen_kvm_libvirt_xml script. I’ve modified the following files:
- util/data.c
- node/handlers_kvm.c
- node/handlers.{c,h}
- node/test.c
- node/client-marshall-adb.c

Most important the allocate_instance() function that is in charge of setting up
the instance metadata a prepare it to pass it to the handler, then
hyphervisor trough Libvirt’s API. The function now has a new archId
parameter as well, to keep coherence with the field name. It also
handles whether the field is set or not. We (Eucalyptus developers and
I) haven’t settled wether to initialize this field with a default value
or not. I’d stepped up and initialized with a NULL value for this string
type var.

if (archId != NULL){
strncpy(inst->archId, archId, CHAR_BUFFER_SIZE);
}

Stores the value only if it’s passed to the function. This is essential to
don’t break existing functionality and keep consistency for later releases.
With this we almost finished the part of extending Eucalyptus to support
arm images. It took quite long to get to that point. Next step: test.

As I mentioned in my previous report the current Eucalyptus packaging
has issues. From the beginning I’ve approached the pkg-eucalyptus team,
who were very hepful. So I myself set me up and joined the pkg team with
commit access to the repo. Even the GSoC is not intended for packaging
labour, I needed to clear things on that side because what we want is
adoption so anyone, say a DSA or a user, could setup a cloud that has
support for running arm instances under amd64 arch.

Over the weeks between mid-term evaluation and past week I’ve worked on
that front. Results were good, as you can see in the pkg-eucalyptus
mailing list and SVN repo.
Eucalyptus has a couple of issues that because of it’s nature and complexity
triggered build errors. Those issues came from the Java side of the project and
few form the C-side. The C-part was a problem with AXIS2 Jar used to generate
stubs for later inclusion on build-time. There’s no definitive solution to date
because one of the Makefile on gatherlog/Makefile issues a subshell call that
doesn’t catches the AXIS_HOME environment variable. I’ve worked around this
by defining it as a session env var from .zshrc. The other problem is related
to the Java libary versioning and most likely (we had to investigate further)
to groovy versioning.

As I explained Eucalyptus has 3 components written in Java. The Java code uses
extensively the AXIS2 library for implementing webservices calls, the groovy
language for JVM, and many other Java libaries. Eucalyptus open source version
ships both ‘online’ and ‘offline’ versions. The difference is basically that
the offline version ships the Java libaries JAR files inside the source code,
so you can build with all required deps.

Our former packaging used a file to list which Java libraries the package
depends on and it symlinked them using system wide installed packages. This
rather than helping out triggered a lot of problems I explaing with more detail
on the pkg-eucalyptus ml. I worked around this by telling the debian/rules
not to use such file to symlink and instead use the existing ones from
the source. The last weekend I managed to get to that point and built
sucessfully the software under Debian. I’ve done that in order to have a
complete build-cycle for my changes, and then test. In fact today I’ve
spotted and fixed a couple of bugs there.

What’s available now
——————–
To date we have a Eucalyptus branch where my patches are sent. The level of
extension is nearly complete, more testing needed. One missing bit is to
change the UI so that the user selects which arch her image is and that
value is passed to the corresponding functions on the Node Controller
component.

We also have an ARM image that can be tested and later automated. I’ve
recently learned about David Went’s VMBuilder repo that extends Ubuntu’s
vmbuilder to support image creationg. I might talk to him to adapt the tool
in order to support creation of arm images and use it to upload to an
Eucalyptus cloud.

I’ve also created a wiki page with different bits on which I was working on.
I’ve yet need to craft it to be more educational. I guess I’m going to use
this report as a source :)

We also had more strong cooperation with the Eucalyptus project and
involved their developers on the packaging and this project, which is
something I consider a great outcome for this project and GSoC goals:
to attract more people to contribute to FLOSS. I’ve also been contacted by
people from the Panda Project and we might cooperate also.

Future work
———–
I plan to keep working on the project regardless the GSoC ends. Our goal
as Debian could be integrating this into the Eucalyptus upstream
branch. We have good relations with them so expect news from that side.
I also plan to keep working with the Eucalyptus team and related
software in Debian, given that I’m familiarized with the tools and
projects.
I’m also planning to advocate SoC for Debian in my faculty. To date we
had already 4 students, IIRC, that have participated in the past.

Project challenges and lessons
——————————

During the project I faced many challenges both in the personal side
and in the technical one. This part is a bit personal but I expect we
learn from this.

First challenge was the ‘where do I sit’ problem. My project was
particular, indeed quite different from the others on it’s nature. I had
to work on a software that is not Debian’s and then come and say ‘Hey we
have this nice tool for you, come test it!’. So, indeed, my focus was on
the understanding of such tool, Eucalyptus, and not much on looking back
at Debian because I didn’t feel I had something to advertise yet and
indeed I got most valuable/useful feedback from Eucalyptus developers
rather than Debian’s, which for the case is OK IMHO. I had great
mentoring. This situation probably looked a bit of ‘isolation’ from my
side, from Debian’s POV, but it was not intended it’s just how it needed
to be IMHO. I felt that I wasn’t contributing directly to the
project. I’ve spoke about such thing with Steffen a couple of times. I’d
like to say that it was also my concern but I probably failed on
communicating this, second challenge.

Third challenge was more technical and related to the first one. Since I
was not writing any code for a Debian native package/program but instead for
other project I faced the situation of where to publish my
contributions. Eucalyptus had some issues on managing their FLOSS repo
and the current development one is outdated comparing to the
-src-offline 2.0.3 release. The project didn’t fit pkg-eucalyptus repo
neither, even we thought to branch the existing trunk and ship my
contribs as quilt patches, but it involved a lot of more work and burn
on reworking something that has issues now. Later on time I branched the
bzr eucalyptus-devel Launchpad repo and synced there with the
src-offline code. I was slow to react on thing I can say.

Fourth challenge was also technical and still dealing with. I was looking to
setup a machine to set a cloud and test my branch. The Dean of my faculty
kindly offered a machine but I’ve never managed to get things arranged
with the technical team. Steffen and I discussed about this and evaluated
options, at the end we settled on pushing adoption rather than showcasing it.
Since for adoption we need a use case, I’ve spend some SoC money on hardware
for doing this. I should have news this week on that side :)

Finally, I’d like to thank everyone on the Debian SoC team for this
opportunity to participate. I like to thank Steffen for his effort on
arranging things for me, Graziano from Eucalyptus for his advice on
working with the software code. The different people from Eucalyptus I
interacted with and showed interest on the project’s sucess. My
classmates and teachers from the Computer Science School at UCSP in
Arequipa-Peru, friends from the computing community in Peru – SPC and
finally my family. Thank you, I learned a lot, specially on the personal
side. As Randy Pausch put: “The brick walls are there to give us a
chance to show how badly we want something.”

What was done so far
——————–
- Extended the ncInstance_t struct on util/data.h adding the archId
parameter. This struct keeps the information regarding a node (nc),
say RAM, Kernel, etc. Currently it has no way to set an arch in order
to be used later.

typdef struct ncInstance_t{
...
char reservationId[CHAR_BUFFER_SIZE];
char userId[CHAR_BUFFER_SIZE];
char archId[CHAR_BUFFER_SIZE]; // arch field added
int retries;
...
}
The Eucalyptus team was OK with this approach that I’ve proposed few
weeks ago. For all my changes the approach is maintain compatibility
with existing features.
We still have to define if we are setting a default value, say amd64,
or keep it unset until the user sets one. For now we will be supporting
amd64 and arm as valid fields.

- Modified the allocate_intance() function to support the archId
field. This involved adding a new parameter and detecting whether its
present and setting de value accordingly. This function is later used
by the doRunInstance() function in node/handlers_kvm.c

- Modified the involved functions that are called by the KVM handlers
and result in passing parameters to the XML file generator for being
used by libvirt’s and KVM and have the image running under
Eucalyptus. The new parameters and field are not required and only
being used if they are set with a value. The archId parameter has been
added as the last one, so existing function calls can work. This could
be rearranged later, but will involve a more extensive revision with
Eucalyptus developers.

- I’ve set a git local repo in order to keep track of the changes to
Eucalyptus. Since this part is a sort of a Eucalyptus branch I took
this approach. Steffen and I are discussing whether to release this as
a pkg-eucalyptus branch (as dpatch, using existing packaging). Either
way I’m putting the diff files form my git repo over the wiki and will
put them on my site too. I plan to use git-svn in order to send them
later to the pkg-eucalyptus repo once we are settled with this.

- Updated the project’s wiki[1] page with information regarding all that’s
involved on my work, so it can be ‘re-played’ or resumed later.

What I plan to to over the next weeks
————————————-
- Finish the modifications to the relevant functions. Expected dealine:
next week.
- Do integration tests:
– Write a test program, there’s an example under node/ that could be
helpful.
– Generate the XML domain definition from Eucalyptus functions. The
full cycle: handler_kvm -> allocate_instance -> get_instance_xml ->
have the XML file properly generated -> qemu-kvm runs the instance
using the proper emulator (arm in our case).
- Test runnning the image I’ve worked on the project’s begining.
- Fixing bits and cooperate with the pkg-eucalyptus team on the
packaging bits.
- Talk to Eucalyptus so they adopt our patches.
- Rock and roll :)

What would be nice to have after the project ends
————————————————-
- The Debian packaging *needs* work. I’ve already discussed this on the
pkg-eucalyptus mailing list. I’ve also committed myself to help on
that side even after the SoC ends.
- Talk with upstream and Ubuntu to coordinate the packaging efforts and
modifications to the software.
- Get adopters to use our work :)

By now, few weeks about to finish the SoC, I can say that it’s been a
good experience and as I stated I’m planning to keep maintaing/working
on the software after that. I’ve already joined the pkg-eucalyptus team
and plan to contribute actively. I’m sad I didn’t managed to get Debconf
this year, time was a constraint again, hopefully we can meet in 2012! I
guess that all by now!

Best regards,
Rud

People at Eucalyptus has been very helpful and willing to cooperate with us to make this project a success. We expect to get them involved on the packaging and probably as Debian contributors, if not developers, also. Next week is the official coding phase start, but I’ve been talking and working together with my mentor Steffen and the Eucalyptus people already. We’ll be starting working on the qemu ARM images, reusing and resuming the job did by Dominique Belhachemi in the past GSoC.

Of course I welcome as much feedback as you might find useful. I plan to post a project update every two weeks.

Debian’s social contract 4th item states:

Our priorities are our users and free software We will be guided by the needs of our users and the free software community. We will place their interests first in our priorities.

When we make decisions, either technical, legal and others regarding the operating system we deliver, this is one of the most referred argument. Altough that’s seen as high priority often we don’t have ways to properly know what our users want. While working on translations on the Spanish team we’ve faced this situation. Do our users find them useful? they are able to understand them? they find that a much familiar wording would be bette than high technical details? We didn’t know. Then, the question still exists.

Altough Debian has ways for users to provide feedback (BTS, mailing lists, IRC,  popcon, etc) none of them is designed to offer a way for the user to provide feedback on features, development roadmap and other non-bug aspects that developers and the project can tally and use for prioritize on releases. It’s rather amusing to note that one of the most valuable assets free software community has is user involvement and contribution.

But before we enter in details let’s start on the basics. For using this information we first need to know who our users are? do we? From my findings and interaction with the community I’ve identified two kinds of Debian users who can be clearly named.

1) The derivatives or pure blends, who use the Debian base and framework to build niche distributions.

2) The lead users (using E. Von Hippel’s definition), who are the developers, contributors and a group of users. Debian is, if not the only, one of the projects who is best for fostering lead users. Most of them at some point involve themselves in the development process and some, later become developers.

There is a more diverse group who are end-users but it’s unclear to me how we can group them. Despite that they probably represent the biggest part of the pie.

So, how we do please everyone? can we? In my opinion we can, at some degree. By implementing tools for first: gather user feedback, make statistical data, tally, we later can take informed decisions. In Debian decisions are voted and the set of people who votes are only developers with their own constraints.

I think this would ease the constant that release-decisions-regarding-foo-tech-legal-issue represented on each release iteration, saving time, health and bits.  It could be useful for knowing more about who are the ones we develop things for. I’m thinking of some sort of Dell’s IdeaStorm.com for software.

What do you think? I’m willing to co-mentor this if someone finds that is an interesting project for GSoC. Let me know!.

Latest weeks I’ve progresivily started to get back on track with my Debian duties. Took care of my packages, update some information, kept track on current issues and hanged on IRC. While doing that I’ve found some issues I’d like to elaborate on later, so we could improve things. So, expect me to be more active and post updates about my findings. It’s good to be back!  I’ve missed you guys :)

Hoy, el desarrollo que ha alcanzado el ecosistema de software libre ha permitido que cada vez más organizaciones, empresas, e instituciones adopten las soluciones de software creadas por éste. Por un lado, estudios recientes, como los de Gartner, señalan que para el 2012 gran parte de los productos comerciales de software emplearán componentes de software libre y que por lo menos una tercera parte del presupuesto de las empresas para software de aplicación se destinará a servicios de suscripción.

IDC said “Open Source is the most significant all-encompassing and long-term trend that the software industry has seen since the early 1980’s.”

Gartner predict that “ By 2012, 80 per cent of all commercial software will include elements of open-source technology. ”

A survey of nearly 1000 IT staff in the UK, Germany, France and North America, commissioned by Actuate, showed that fifty four percent of businesses in the UK felt that the benefits of open source outweighed any negative aspects

Another Gartners top predictions for 2008 is that “by 2012, at least one-third of business application software spending will be as a service subscription instead of as a product licence”.

Por otro lado, esto también presenta una situación en la que la demanda de profesionales con conocimiento de tecnologías de software libre se incrementa, mientras que la oferta parece ser cada vez más escasa, según demuestran estudios de Actuate.

Research conducted for Actuate found that six in every ten respondents said there “were serious problems finding the right IT skills to implement and manage open source solutions”

El pasado sábado 22, tuve la oportunidad de ofrecer una charla en mi universidad, la UPC, en la que desarrolle estos temas. El enfoque tenia como objetivo el saber cómo aprovechar, inteligentemente, como estudiantes de computación, las oportunidades y recursos que existen hoy para desarrollarnos profesionalmente haciendo lo que nos apasiona: software libre. En este sentido, conversamos acerca del programa Google Summer of Code como una manera de avanzar hacia tal objetivo, por los beneficios que ofrece a nivel académico y profesional. Además, presenté el proyecto OSS Watch, cuyo objetivo es fortalecer el vínculo entre la comunidad académica y la de software libre a través del desarrollo de material académico que introduzca prácticas de desarrollo de la comunidad en los cursos de computación. A través de esto el proyecto busca mejorar las capacidades de los futuros profesionales que les permitan desarrollar soluciones basadas en tecnologías de software libre.

La charla estuvo organizada por el grupo GNU UPC, conformado por alumnos y ex-alumnos de la universidad, que está en un proceso de reactivación de actividades y retomando proyectos a futuro, de los cuales seguro tendré algún grado de culpa. Las diapositivas de mi presentación están en el wiki que he creado para publicar mis trabajos academicos y proyectos personales.

Finalmente acepte y empece a trabajar precisamente el 1ro de enero del año siguiente. El entorno de la BVL era más tranquilo, no tenían grandes servidores ni cosas sofisticadas; sin embargo tenian algunos elementos que eran bastante interesantes para mi, y creo que claves en mi desarrollo: el proyecto era relativamente nuevo asi que había algunas cosas por construir, había un esquema de telecomunicaciones con los distintos agentes de bolsa a través de un sistema ATM usando el protocolo x25 (antecesor del modelo OSI, TCP) -también conocido como MEGANET en TdP-, el ambiente era tranquilo, teniamos acceso a Internet y el grupo era bastante ameno.

En este lugar es donde logre desarrollar un conocimiento de buen nivel sobre el sistema operativo OpenVMS, a punto que recibia constantes consultas de los nuevos operadores que ingresaban a GMD y de algunos desarrolladores. Mis inicios fueron en el turno de la noche, donde básicamente se procesaba información e imprimia reportes para el día siguiente, ejecutaban respaldos y se aprovechaba parte del tiempo para dormir. Recuerdo que mi primera noche me recoste sobre el sofá que mis compañeros me recomendaron y no desperte hasta las 7am, todavía no me adaptaba; de hecho antes de eso no acostumbraba a desvelarme.
En algún momento pase al turno de la tarde donde tenia que interactuar con usuarios, vestir formal (cosa que jamas me incomodo, salvo cuando me “sugirieron” que use el cabello más corto -obviamente me rebele!-), y sobretodo conocer en persona a los CVL$algo, osea los usuarios, de entre los cuales había algunas guapas chicas; cosa que felizmente parece ser una constante.

Con el pasar del tiempo logré automatizar algunos procesos en los servidores, escribi cientos de programas en DCL, y en algún punto practicamente tenia todo el tiempo libre consecuencia de eso. Logré configurar el stack TCP/IP (ya que esos equipos solo funcionaban en red con el protocolo DECNET), ejecutar y navegar en Mosaic desde el entorno Motif de los servidores Alpha para ingresar a Internet y los servicios en los que ya era ávido usuario (confesión). Descubri todo el mundo detrás de OpenVMS, las conferencias DEC, los grupos de usenet, de los que aprendi, además de incrementar mi interés en conocer el tema en más bajo nivel.

Ocurrio en algún momento que llevamos un curso de Unix, del que ya había oido porque un usuario del chat de Yahoo! lograba hacer cosas que otros no y me dijo que sabia Unix y que debería aprender puesto que todo ese chat estaba sobre Unix. Rápidamente busque en Altavista o Yahoo! y aprendi qué era este Unix.

Luego de la primera clase estuve más seguro de que si queria aprender esto. Lamentablemente desde mi sitio no tenia forma de acceder al servidor en la red de GMD que estaba en el otro edificio. No contento con esa limitación empece a investigar en Internet hasta que encontre la luz: Linux, un sistemas imilar a Unix que se podía ejecutar en una PC. Los siguientes pasos fueron reciclar unos discos duros de 500MB, reducir el espacio usado por Windows 95 en la PC (Pentium 33Mhz, 16MB RAM) que tenia asignado, descargar durante 1 mes -debido a que reiniciaban el equipo y la descarga FTP no tenia “resume”- una distribución de Linux (creo que RedHat 5.x), y tratar de instalar y configurarla, cosa que logré luego de algunos días.

Cierto día buscando información di con la página del Proyecto GNU y leí su manifesto, e inmediatamente coincidi con el mismo. Esto me animó bastante a conocer, usar y promover esto que ahora sabía que se llamaba software libre. Posteriormente supe que habían distribuciones y encontre a mi subsiguiente amor: el Proyecto Debian. Luego de leer su contrato social, manifesto y las directrices, en donde percibi claramente que cualquiera podría contribuir a éste, levante la mano y dije: yo también. Hasta antes de eso no había sentido tan cercano el hecho de que, además de usar algo, también podía hacer cosas para hacerlo mejor y que beneficie a otros como efecto secundario. Esto claramente fue amor a primera vista, de los cuales uno nunca se separa.

Reemplace el RedHat por Debian, que por ese tiempo era complicado de instalar; lo instale en la PC de mi casa, que había adquirido recientemente, y decidi enlistarme en el grupo de traducción como punto inicial de mi contribución.

De las anécdotas de ese tiempo recuerdo una cuando el nuevo jefe de sistemas, ex marino, ingreso al centro de cómputo para mostrarlo a una visita y empezo a describir las actividades y equipos que teniamos. Al señalar mi PC, ejecutando GNOME 1.x, con una terminal ejecutando top y alguna otra cosa, dijo: desde aquí monitoreamos todo. Tuve dos sensaciones, la primera la obvia (no tenia idea de lo que estaba pasando allí -ya que yo mismo me autorice a instalarlo-) y la segunda fue un poco de ego que me decia: exacto, tengo el control de todo esto (cosa que tampoco estaba lejos de ser cierto).

En algún momento, años después cuando ya había salido de GMD, fui a ayudar a mi amigo Oscar con un tema de backups y para sorpresa mía se trataba de uno de los programas que hice tiempo atrás. Finalmente llegaron a usarlo (Oscar era reacio porque no quería olvidarse las órdenes y sus parámetros) y replicarlo en otros proyectos, fue bastante halagador :)

This escenery renders almost imposible to have a decent timeframe for me to be able to stay for more than 24 hours at Argentina. This is bad since, besides willing to speak about my recent work and seeing old friends, I also did want to visit my father’s family on La Plata and have lot of fun at ‘La ciudad de la furia’ aka Buenos Aires, wich I happen to like a lot.

I still plan to find ways for me to be able to present my talk, since I noticed it’s been accepted!. Maybe I can run a non-RL debconf in Second Life ;)

Anyway, life isn’t this bad at all. I’m afraid I’ll be enyoing a wonderful vacation with such insuperable compannion soon. So, expect me to dissapear of the known world and to return from the sky. Looking forward to that moment! :)

In the last couple of months I’ve been working on a paper which intends to offer a (not so) new -as you might notice after reading it- approach to what the Debian Project have been managing to produce and what can be done to keep doing it better in the new escenery that we are and will be living in the upcoming years.

My work describes the way Debian have been sucessfully producing lead-users, as described by Eric Von Hippel’s Democratizing innovation book, since it’s conception and what elements were key to have done so. Previously it takes a look on how the process of innovation is really done. Then it describes the current and future world’s escenery according research and current trends, later it makes links between them and gives some ideas for us to keep fostering innovation and play a key role in the free software ecosystem.

With this work my intention is for us to understand what we are, what are we good doing, and how we can keep rocking! I want Debian to look further and be the free software development cutting edge project and atract bright people to work on what they are passionate about.

Hopefully I’ll be in Mar del Plata to discuss about this and also have some fun with you guys I haven’t seen in years!

I’d appreciate any comment or feedback to this. My intention is to turn this work into a collaborative fashion that allow us to make our project much more wonderful!
