In continuing with my Linux From Scratch series with Part 3, I present my adventures in setting up a more productive desktop system. Up until this point I have concentrated on just getting the basic underlying system in place and later installing X and a window manager. Today we strike out on our own some as we venture out of the docbook to go beyond Beyond Linux from Scratch.

Ubuntu/Canonical: The State of Robotics and Buzzwords

  • The State of Robotics – March 2020

    Damn it March. 2020 was doing so well. The biggest news last month was the dramatic escalation of COVID-19. We won’t go into any detail, I’m sure you’re seeing enough of that. But due to the outbreak, the state of robotics this March has been, heartwarming. We have seen a surge in online learning platforms, companies, startups and communities rising to the challenge. Members of open-source communities across the world are doing great things, with and without robotics, to support whoever they can. In this blog, we first want to highlight at a few responses to COVID-19 using robotics. And then it’s back to usual programming, highlighting robotics work and projects we have seen or done in March. If we have missed something in particular, please reach out to robotics.community@canonical.com and let us know.

The cataloging of free software

The Free Software Directory is a collaborative catalog of software aimed to be the primary source for representing all free software. Each free program has its own page in the Directory from which it is possible to study the evolution it has undergone in both technological and legal terms through a chronological system similar to that of Wikipedia. Each catalogued program is distinguished by one or more aliases, and accompanied by a huge amount of information, which goes beyond the pure needs of the end user. Snapshots of the graphic interface, detailed descriptions, change logs, links to social pages, and lists of licenses and dependencies are examples of all the useful information which can be carefully attached by users to each page. Everyone can freely subscribe to the Directory and create new pages, but only the pages reviewed and approved by administrators become visible and indexable. Administrative approvals are always made according to strict rules aimed at preventing the spread of proprietary content. As on Wikipedia, each user can have a self-approved personal page, where they can define their identity and discuss with other users. Users can also include sub-pages on which to publish their thematic articles, and any tools useful for the daily life of the Directory. User access rights are assigned to active users, and all those who demonstrate that they have the necessary technical skills and wish to devote themselves daily to the care of the pages have a chance to be welcomed onto the staff. This serene and flexible organization, based on bonds of trust built on facts and adherence to well-defined common ideals, guarantees that the technological and social development produced by the project is gradual but unstoppable. Thus, any investment of time by volunteers is amply repaid. The project has proved to be a clear success, so much that over the years it has received funding from UNESCO, and is still supported by the Free Software Foundation. The portal boasts the participation of more than 3,000 users from all over the world. Since its creation, it has accumulated more than 80,000 verified and recorded revisions for posterity in the chronology of the MediaWiki pages, all of which are dedicated to facilitating the essential freedoms in more than 16,000 free programs. The portal's ability to adapt and survive was possible not only because of the technical creativity of the staff, but also by the solid ideal at its base. By guaranteeing maximum visibility to free software, it has thus rewarded developers who freely employ their knowledge for the good of humanity. The transition to free licenses is indeed a moral duty of every developer, and the Free Software Directory is deployed at the forefront to facilitate it with great benefit to the world's cultural heritage.
