The People Behind the Learning Portal: Flavio Schefer

LPI, LPI Exam Prep, LPI Exam Preparation, LPI Learning, LPI Guides, LPI Career, LPI Skills, LPI Jobs

Linux Professional Institute (LPI) established its Learning Portal in June 2019 as the repository of all the Learning Materials for LPI’s exams. The project is managed by Dr. Markus Wirtz, LPI’s Learning Materials Manager. The Learning Portal is, since its very beginning, an international endeavor, because learning is easier if you can study in your mother tongue.

This series of interviews is a journey toward knowing better “the People behind the Portal,” the team of authors, editors, and translators that designs, writes, and localizes the lessons and the site itself. By reading this series of interviews, you will know more about the contributors’ work and why working on the Learning Portal is quite cool and nerdy! 

In this issue of the series we make the acquaintance of Flávio Schefer. Brazilian, 22 years old, Flávio started his IT career at LPI as a peer reviewer. His interest in Linux was sparked when he became friends with Cesar Brod and the Latin America Team of LPI. Currently, he's employed as a quality assurance (QA) engineer at IBM. 

What is your academic and professional background?

I am an International Relations student from Brazil, currently working as an Automation QA engineer at IBM.

When and how did you decide to use your skills to develop learning materials for Linux Professional Institute?

I first joined LPI as a volunteer translating learning materials, because I have been studying English since I was 14 years old. That happened on September last year, and I joined the project because after I had done that livestream with Cesar Brod (Community Engagement Director - Spanish and Portuguese Regions) and Jon “maddog” Hall (Board chairman) I just fell in love with the FLOSS world and decided I needed to be a part of it.  

What is your contribution, so far, to the Learning Portal, and what’s next for you in this project?

As for today (February 4, 2021), I reviewed the Portuguese translations of LPIC-101 materials that are now released free for everyone at learning.lpi.org. About what I will be doing, I do not know. But I’d love to help with materials for the LPIC-2 exam, which I am studying for, and many other new projects LPI is preparing for this year.

As a certified professional and a developer of learning materials, you are familiar with both sides of the coin. What advice, therefore, would you give to people studying for their LPI Exams?

I’d say: “Study. Use the free materials we write and translate for you. If you need classes, there are many good ones online. Do exam simulations, they are really important (Our learning materials tend to include exercises and questions at the end of a lesson), but above all else, practice. Run Linux at a Virtual Machine, if you do not like ng it permanently on your own hardware, and test the commands on your side too. Read the actual configuration files. Study, practice, and you will pass with ease.” :)

What advice would you offer to teachers and, in a broader sense, to others involved both in the use and production of Linux and Open Source learning material?

I am not as close of being capable to answer such a question as I am for learning the systems. :-P But I would ask teachers to keep their materials as simple as possible. Many people, especially those my age, are scared of Linux because they think it’s just a black screen. Make people see how fun to learn and useful Linux is, and make them fall in love with it too.

The LPI Learning Portal is a community too. What is your experience with this community so far? What tools and features do you use in the process? What can you tell us about workflow? And what “opensourceness” can you recognize in a project that is about education?

To be honest, I never had much contact with other translators, so I cannot say anything about it. But Dr. Wirtz (the leader of the Learning Materials team) is always very, very helpful and adapts the workflow to our knowledge and availability. So, even if you know very little, or even nothing at all, about Linux, you can help us. I am sure there will be a chore that will fit you perfectly. As for the last part of your question, I believe that the main aspect of open source can help education is by letting people learn on the job, no matter on what level they are, and letting everyone that uses the material, software, or whatever make it even better and fix problems. Quoting Eric Raymond “Given enough eyeballs, all bugs are shallow.''

Localizing IT Training content: hurdles and solutions

What specific hurdles do you have to deal with while translating the Learning Materials into your mother tongue? What are the possible “lost in translation” issues?     

We know technology has a very specific vocabulary, which is very hard to adapt into any language other than English. Besides, we have to write material that anyone can use, no matter the knowledge they already have. So sometimes a sentence may be a little “hard to read” if the topic is too complicated. We do our best to make our materials as simple and available as possible, but it is no easy task. Sometimes I may come up with a bad adaptation, so please forgive the mistakes :-P 

What is the story of FOSS and Linux in your country, from your point of view?

I know that it’s quite an old story. For some time, the government even had a preference for using FLOSS, which Cesar Brod was a big part of. We have many big initiatives like the C3SL (official distribution repositories mirrors at a federal university) and the GNUTeca (a library management software). Brazil has always been a fertile place for the FLOSS culture, and there are many conventions and events on the topic as well. But I have not kept up with any new projects, unfortunately. 

How do you see the impact of your work with the LPILP Team, and the development of projects such as the Learning Portal, in your country in a few years?

I believe that our work as volunteers can bring many people to get to know the Linux world. And I even got to know a few people that got certified through our materials and reached me on social media to ask how they could join LPI’s team. So I truly see our work making a very big difference and bringing fresh blood to the community. Besides, our materials, as they are free, can be used as a basis for people who want to teach Linux to impoverished people, for example, doing social work on the go as well. Quite nice, don’t you think?

Vircadia Pushes Open Source Ahead in the Metaverse

LPI Exam Prep, LPI Certification, LPI Career, LPI Skills, LPI Jobs, LPI Preparation, LPI Material, LPI PDF

VR, AR, and virtual worlds have been a major focus of the computer industry for some time, spawning many expensive devices and a spike of interest in the early 2000 decade for the Second Life virtual world. Improvements in visual effects and other parts of the technology over the past few years suggest that VR/AR is indeed ready for a breakthrough.

When the Linux Professional Institute learned of Vircadia, a free and open source metaverse project, the institute knew it had to get on board. Vircadia creates a platform for virtual worlds, which major companies such as Microsoft and Facebook (now Meta) are treating as a crucial next stage in user experience.

But if VR/AR remains proprietary, its progress will be stunted and software that holds the end user’s experience with the utmost priority will be lacking. Thus the Vircadia project was born. In this interview, Andy Oram asks Kalila Lakeworth, the founder and leader of the project, about the history and progress of Vircadia.

How does the VR experience on the web differ from the experience on a dedicated device, besides some loss of an immersive experience? Does Vircadia work similarly in both environments?

To begin, the web experience will be quite basic but interactive. WebGPU can potentially enable more sophisticated graphics processing, speed up response time, and open up 3D graphics possibilities by giving browser-based applications access to GPUs. As development progresses and features like WebGPU mature, I expect we’ll be able to bring the web and native experiences to feature parity.

How much background does a user need to create or alter a world in Vircadia?

It all depends on the complexity and detail of the world desired. The world creation UI is probably familiar to world builders coming from existing social virtual platforms. We are working to build out a marketplace of content to ease the burden. However, for a truly bespoke world, having expertise in scripting and modeling will be most valuable.

Was it hard to find contributors for Vircadia? How did you promote the project, do outreach, and motivate contributors?

Very difficult, as is the problem that faces most open source projects I’m sure. Promotion generally was only by word of mouth but I found that to be insufficient. Fighting against the control of large corporations and their governments in virtual worlds is a hot topic thanks to the industry’s explosive growth, fueled in part by Meta. One strategy that has worked well has been to approach tinkerer and developer-oriented communities such as the one surrounding Linux.

How did your project come to the attention of LPI, and how did their support help you? Was the support just financial, or did it include stuff such as publicity and organizational support?

After one of Vircadia’s first major public announcements on Reddit, LPI got in touch with us. LPI offered to partner up and assist with publicity and grants. We are always looking for ways to expand accessibility for open source virtual worlds, so when LPI approved our request for a grant to build the infrastructure needed to enable web support, we were very glad. LPI being a rather large organization, things were much easier than I had expected they would be.

What other organizations provided support?

We’ve worked and are working with many organizations to build and maintain virtual worlds powered by Vircadia. For example, we’ve put on art exhibitions for non-profits, created commercial worlds for prototype simulation and showcase, and built and hosted startup conferences in collaboration with the Taiwanese, Japanese, and Indian governments; I could go on forever, but to be brief, organizations and companies of every type are finding Vircadia and we receive support to help make it work for their needs.

What is “metaverse” and where does Vircadia fit within it?

Metaverse has fast become a buzzword to toss around, but even prior to that people had always misunderstood what metaverse is and what it isn’t. Metaverse is defined as being a virtual world, but to me it’s much bigger than a single world, or even a set of worlds. Take for example the “internet”—it’s an all-encompassing concept of a wider abstract network of things. As such, I think “metaverse” is the same concept, except with virtual worlds. In my opinion, metaverse is the culmination of all virtual worlds built on top of the network, in this case the internet.

Vircadia is part of the infrastructure layer for metaverse. We aren’t trying to build VRChat or Horizon. We want to be the middleware that goes into those platforms, but also games and experiences as well. Vircadia’s scalable infrastructure provides everything from simulation to economies for virtual worlds and is ripe to support the inevitable metaverse filled with millions of worlds.

Who thought up this project, and when? Did it go through various stages and transformations, as many projects do?

The history of Vircadia can be traced all the way back to the early 2000’s. Philip Rosedale originally created Second Life, which was and still is quite popular. Afterwards, he went on to found High Fidelity. The platform was built with some cutting edge technology, but it had its ups and downs and ultimately was abandoned in December of 2019. It was at that point that I had decided to take my own build and adopt the project in its entirety; thus Vircadia was born. Now, to get to where we are today, we’ve gone through a lot of rough patches. Nothing about this has been easy, nor do I expect it to be as we push farther to grow Vircadia’s ecosystem.

Can you briefly compare Vircadia to Meta's Metaverse?

Vircadia is an open source metaverse ecosystem; Meta’s ecosystem is proprietary. We want to empower the creation of not thousands, but millions of independent virtual worlds. More worlds means more competition and thus more niches fulfilled and a higher standard of quality across the board. We are laying the FLOSS foundation to enable freedom of choice for every user in the metaverse and we are able to do it with the support of friends like LPI.
