Analysis of free software communities: coda

As you can see in my last posts (I, II, III, IV and V), I finally managed to translate the paper we released last year in V jornadas de SIG Libre (please, beg my english!). It took me a year and my wisdom teeth removed to find the time. Our intention (Fran and me) when […]

Analysis of free software communities (V): generational analysis

Disclaimer – this post is part of a serie: I, II, III, IV and V (this one). Images: on the left, contributions of top 3 developers along the project history; on the right, evolution of developers participating during 2010. Data: trunk from project repositories during the period 1999-2010. Is it something we could extrapolate from the data there? This indicator gives us some […]

Analysis of free software communities (IV): community workhours

Disclaimer – this post is part of a serie: I, II, III, IV (this one) and V. Images: on the left, number of changes to the codebase (commits) agregated by hour of day. On the right, number of commits grouped by day. Data: trunk from project repositories during the period 1999-2010. Is it something we could extrapolate from the data there? This indicator […]

Analysis of free software communities (III): activity and manpower

Disclaimer – this post is part of a serie: I, II, III (this one), IV and V. Images: on the left, the number of changes to the codebase (commits) agregated by year. On the right, the number of developers with at least 1 commit that year. Data: trunk from project repositories during the period 1999-2010. Is it something we could extrapolate from […]

Analysis of free software communities (II): adoption trends

Disclaimer – this post is part of a serie: I, II (this one), III, IV and V. Find below the statistics for mailinglist activity in GRASS, gvSIG and QGIS during the period 2008-2010. The first one shows data from the general user mailinglists for each project. Take into account that data for gvSIG agregated both international and spanish mailinglist due […]

Analysis on free software communities (I): a quantitative study on GRASS, gvSIG and QGIS

Disclaimer – this post is part of a serie: I (this one), II, III, IV and V. When selecting an aplication, it’s very common to weight tecnological factors -what the aplication enable us to do?- and economic ones -how money do we need?. And yet, there is a third factor to take into account, the social aspects of the project: the […]

gvSIG codesprint in A Coruña: a personal summary

As you may know, iCarto and Cartolab have hosted a gvSIG codesprint at the nice city of A Coruña. iCarto was kind enough to support my attendance to the event to work on gvsig, navtable & navtableforms. Find below some comments on my personal experience. Some general impressions on the event It’s great to see […]

Análisis de comunidades de Software Libre (I): resultados de un estudio sobre GRASS, gvSIG y QGIS

El primer post de una serie, que presenta los resultados de analizar cuantitativamente 3 comunidades de proyectos de software libre, de cara a comprender mejor cómo funcionan.

Abella y la importancia estratégica del software libre para España

La pasada semana Nacho y yo estuvimos en las II jornadas de SIG libre de Girona. Desde luego fueron muy interesantes. Para alguien que está todavía aproximándose al mundo del SIG, ha sido el evento donde descubrir la verdadera fortaleza de la comunidad libre en España con proyectos tan importantes como gvSIG o Sextante.. pero […]
