YAPC::Europe 2015: Something dies in your soul when a friend is leaving.

The European Perl conference of this year is over.


During the week from 31-Aug-2015 to 5-Sep-2015, Granada has been hosting the YAPC::Europe 2015; a Perl conference in which GeNeura Team has been one of the main organizers. Along these days, more than 250 professionals, most of them Perl developers, have been talking, listening, discussing, laughing, singing (at least Larry Wall did it), offering employment opportunities, and sharing drinks and tapas around a single main topic: Perl.

It is never easy to organize a conference, and YAPC has a singularity: is  probably-the-cheapest-international-conference (regarding the prices for delegates) I’ve ever been. Anyone having a talk accepted (except for lightning talks) received a free registration which included all the goodies (bag and T-Shirt, among others), and tickets for pre-conference dinner, lunches and gala dinner. There were also some courses organized under the scope of the conference, but registration was separate. Having all of this in mind, YAPC Europe wouldn’t be possible without the sponsors. For this reason, first of all, let us thank  all the companies and people that have supported this event (you can see all of them at nothing could have been written about this conference without their generosity.

The venue for YAPC::Europe 2015 has been the Faculty of Sciences of the University of Granada. For this reason, the conference started with the pre-conference dinner, where all of us shared a some bits (in fact, a good amount of) pizzas seated on the grass of the venue’s backyard. Thus, from the very first moment, we realized that YAPC is mainly designed to keep people, the community, in touch. More than sharing knowledge (although it is shared), showing solutions (and they were shown), or talking about “one’s book”, YAPC allows you shaking the hands that wrote the CPAN module that saved your project a few months ago, or seeing the smile of that costumer whose business mainly depends of Perl’s good (unique?) programming features.

During the three days the conference lasted, plenary talks took place both at first and last hours. Thus, the central hours were dedicated to parallel sessions with talk lasting 20 or 50 minutes, with a small gap between them, so that people can move from room to room attending to their favorites talks. It’s rather difficult, if not impossible , to make a summary of all of them, so, both the schedule and list of accepted talks will be available for a long time, just in case anyone is interested.

Last day was probably the big day. Larry Wall was talking about Perl 6… Well, and also about lot of things related to Tolkien’s books and their similarities with Perl 5 and Perl 6. Larry invited us to the party, i.e., the upcoming release of Perl 6, that will be available in Christmas (in fact, this was not the first time he pronounced this sentence… but it’s the first time that he indicates the exact year for those “Christmas”, and is 2015!!!). We’ll never would be able to thank him enough for being with us in Granada, and will never forget him… as well as their hats.

Together with Larry’s talk, probably lightning talks have been the most important discovery in this conference. Far away from extremely, perfectly, and strictly organized and exposed speeches, lightning are 5-minutes length talks that give the opportunity to show new CPAN modules (or also preventing people for spending their time writting modules for solved problems, i.e., ) , your analysis of the use of a given module, the importance of making web analytics… and, most of all, of being in contact with Japanase developers (sorry, fast developers). Lightning talks are dynamic, illustrative, interactive, fun, necessary… essential!!!!

Finally, as this YAPC::Europe was devoted to art and engineering, let us say “good bye” to the attendees with two songs. First one is a typical Andalusian song, that could be translated into “Something dies in your soul when a friend is leaving”. But, as far as I’ve could seen, probably the best song that reflects what programming in Perl means is Joe Cocker’s “With A Little Help From My Friends” (… Maybe Frodo Baggins and the Fellowship of the Ring would fully agree with me… maybe not.

BTW, YAPC::Europe 2015 is done; so is this entry. (Some other thing I learned in a lightning talk – see

GeNeura organizes the YAPC::Europe 2015 conference

GeNeura Team is one of the organizers of YAPC::Europe 2015 conference, an international event where about 300 people are talking, learning, practicing and arguing about Perl, the programming language.

This event is being held at the Faculty of Sciences, in the University of Granada, and is taking place from 2-sep-2015 to 4-sep-2015.

This year, the final talk will be given by Larry Wall!!

Sorteo de pendrives con motivo del día de la Ingeniería en la Escuela Politécnica Superior de Jaén

Con motivo del Día de la Ingeniería y aprovechando la exposición de pósters de investigación que se está realizando en el hall del edificio A3 de la Universidad de Jaén, el profesor Víctor Rivas (copiando la idea del profesor JJ. Merelo :D ) va a sortear unos cuantos pendrives (siento no poder decir cuántos, pero es que aún no está decidido el presupuesto).

Los participantes deberán hacerse un selfie en el que aparezcan junto al póster que Victor Rivas ha expuesto y, a continuación, enviarlo por Twitter (ojo: solo twitter). En el mensaje deberán aparecer citados los hashtag y usuarios siguientes: #jsEO @epsjaen @vrsantos @geneura

La fecha límite de recepción de mensajes será el lunes, 23 de marzo, a las 15 horas.
Podrán participar todos los miembros de la comunidad universitaria de la UJA (profesorado, pas y pdi) tanto actuales como pasados. Cada persona podrá participar tantas veces como desee, pero siempre con fotos distintas.

El sorteo se realizará previsiblemente el próximo lunes, 23 de marzo, a las 20:00 horas, actuando de improvisados notarios mis alumnos de la clase que imparto en el grado en turismo.

Los nombres (mejor dicho, los usuarios de Twitter) de los afortunados ganadores se darán a conocer el día posterior a la realización del sorteo, de modo que puedan pasar a recoger su pendrive por mi despacho, en horario de tutorías, a partir del jueves, 26 de marzo (inclusive).

Feliz día de la Ingeniería.

Enviada la versión definitiva del trabajo “Predicción a muy corto plazo de series temporales de volumen de tráfico rodado mediante co-evolución de RNFBR”

Tras realizar las correspondientes modificaciones indicadas por los revisores del congreso MAEB 2015, hemos procedido a enviar la versión definitiva del trabajo, usando para ello la famosa plataforma EasyChair.
Cabe recordar que MAEB’2015 se celebrará en Mérida-Almendralejo, durante los días 4 al 6 de Febrero de 2015, y estará organizada por el Centro Universitario de Mérida, el cual pertenece a la Universidad de Extremadura.

“The L-Co-R co-evolutionary algorithm: a comparative analysis in medium-term time-series forecasting problems” at ECTA

Our paper “The L-Co-R co-evolutionary algorithm: a comparative analysis in medium-term time-series forecasting problems” was accepted for oral presentation in the latest ECTA-IJCCI conference.

The abstract:
This paper presents an experimental study in which the effectiveness of the L-Co-R method is tested. L-Co-R is a co-evolutionary algorithm to time series forecasting that evolves, on one hand, RBFNs building an appropriate architecture of net, and on the other hand, sets of time lags that represents the time series in order to perform the forecasting using, at the same time, its own forecasted values. This coevolutive approach makes possible to divide the main problem into two subproblems where every individual of one population cooperates with the individuals of the other. The goal of this work is to analyze the results obtained by L-Co-R comparing with other methods from the time series forecasting field. For that, 20 time series and 5 different methods found in the literature have been selected, and 3 distinct quality measures have been used to show the results. Finally, a statistical study confirms the good results of L-Co-R in most cases.
