The LPI, the NFT and the TLAs

LPI Tutorial and Material, LPI Exam Prep, LPI Career, LPI Preparation, LPI Study Material, LPI Guides

Linux Professional Institute (LPI) regularly hosts students and other folks with an interest in a career involving open source. Through internships, we help them gain experience and acquire new skills. In return, we get to introduce (or further expose) these interns to the world of open source software.

This summer, in Canada, we have two students; Alex, who is studying communications and PR, and Rozilyn, who is studying electrical and computer engineering. During a call earlier this summer, the conversation turned into a search for a project that would interest the interns and benefit the open source community.

Read More: 202-450: Linux Engineer - 202 (LPIC-2 202)

We quickly settled on the subjects of cryptocurrencies along with the current mania over non-fungible tokens (NFTs).  The case was made that launching new coins, tokens, or other crypto-assets such as NFTs is now relatively easy, technically speaking, and worth demonstrating in order to demystify the process.

Looking for inspiration, we discussed creating an NFT of each version of LPI's certification objectives since 1999 (similar to Tim Berners-Lee’s "Source Code for WWW" NFT), or an open source counterpart to the cleverly generated CryptoPunks icons and NFTs.

Considering the general interest in crypto-related topics - and, I suppose, because one of the interns' fields of study was communications - Alex and Rozilyn decided to share their project and progress with us in a series of blog postings. I'm certain you will enjoy reading what they learn this summer, as well as what they end up creating.

So without further ado, here's the first check-in from Alex and Rozilyn:

A Brief History of Cryptocurrency 

Cryptocurrency (or “crypto” for short) requires no regulation from a bank or government. Instead, cryptocurrency is managed by software using cryptographic math. Crypto payments are digitally tracked and verified through a financial ledger, now commonly referred to as a “blockchain.”

Though a seemingly recent phenomenon, cryptocurrency was first proposed by American cryptographer David Chaum in 1983, 10 years prior to CERN’s release of the World Wide Web for public use. “Digital asset software” now exists in the thousands, in forms such as Ethereum, Litecoin, and Dogecoin.

DigiCash, the fruition of Chaum’s ideas, became the first cryptocurrency in 1995. In 1997, the same verification systems that would later appear in modern software such as Bitcoin or Ethereum were used for “Bit gold,” a proposal by computer scientist Nick Szabo.   

No cryptocurrencies followed DigiCash until the catastrophic market crash of 2008. Dwindling faith in the financial reliability of banks and government—along with their standard currencies, known as fiat currencies—created an urge for decentralized solutions. One year later, an alternative now known as Bitcoin emerged as open source software.

Bitcoin was published under the pseudonym “Satoshi Nakamoto” in documentation known as the “white paper”. Some suspect a connection to the original Szabo, who has denied the claims. Today, Bitcoin, along with its crypto-counterparts, is a popular alternative to fiat currencies for those seeking a currency controlled by people, not institutions—and of course, to use when purchasing NFTs.

How Cryptocurrency Works:

A financial ledger is a history of money paid or owed by a group.  In cryptocurrency, payments are recorded in a digital ledger, also known as a blockchain, and secured through a digital signature. These digital signatures are uniquely produced with each transaction to maintain the security of a person’s digital “‘wallet,” which stores crypto-coins. 

How much crypto an individual owns (or spends) is confirmed through the blockchain. A transaction is verified by software that retrieves the full history of transactions of that currency up until the transaction. This explanation is a technical simplification, and we invite you to view a more comprehensive video about Bitcoin. But in essence, the history of transactions, or the ledger, replaces the need for physical representations of currency.

Ethereum and NFTs

A non-fungible token (NFT) is a digital file—typically a photo, video, or audio recording—that represents a transaction on the blockchain. “Fungible” means something exchangeable, such as a dollar bill that can be switched for any other dollar bill without any effect on its meaning or value. Therefore, “non-fungible” refers to an object such as  a painting that is unique and irreplaceable.

The twist: NFTs are often valued at millions of USD. The most valuable NFT was priced at $69 million dollars. 

NFTs were first created using the cryptocurrency Ethereum in 2015, entering popular culture two years later with the release of CryptoPunks: 10,000 algorithmically generated punk characters, each of which was 50 x 50 pixels in size and reached a sale price as high as $16.96  million USD for a set of nine (Figure 1).

Figure 1: One of the earliest NFT projects, CryptoPunks, auctioned as a seven-token set at Christie’s for $17 000 000 USD.

CryptoPunk NFTs were coded using ERC-721, which would become the first standardized “smart contract,” a program that manages transactions and stores them on the blockchain.

Ethereum became the blockchain of choice for NFT due to the cryptocurrency’s direct support for token creation and storage—no third-party software was required. Later that same year, CryptoKitties emerged, also using the Ethereum blockchain. Purchases of the collectible cats became so frequent (Figure 2) that the transactions caused the Ethereum network to experience substantial lag in December 2017. The average value of each cat is now $65k, some reaching $300k.

In 2020-21, NFTs experienced another surge in popularity, including NyanCat (near $600k USD), The CEO of Twitter’s first Tweet ($2.5 million USD), and NBA highlights (collectively grossing over $230 million).

How Adam Futureproofed His Career with Linux Professional Institute

Linux Professional Institute, LPI Exam Prep, LPI Preparation, LPI Guides, LPI Certification, LPI Tutorial and Material, LPI Learning, LPI Career
Linux Professional Institute (LPI) has delivered over 500,000 exams to IT professionals around the globe. So why do so many choose the world’s largest, vendor-neutral Linux and open source certification body to help advance their career?

According to Foote Partners report, ‘IT Skills and Certification Index’, there’s double-digit growth in bonuses paid to LPI certified candidates. So, is it the promise of a lucrative career, or is there even more to being certified with LPI?

We asked Adam, from Washington, about his experience of getting into open source, taking the exams and how this contributed to his current success.

“After spending most of my early life learning and then teaching Spanish, Japanese and English as a foreign language, I realised that there wasn’t much progression in this profession – so decided to take a different path.

“I’ve always been interested in technology trends and saw potential in learning a programming language, so began learning about Linux in around 2007. I really felt that, if I was going to establish a new career in software development, that I had to understand and be able to work with Linux, first and foremost. Since I lacked any industry experience I decided to take the LPIC-1 and Linux Essentials certifications.

“I had to upskill to prepare for the exam, and I began by using Linux Academy and their training tools; I read lots of “Intro to Linux” books and study guides; I went to meetups and networking events to talk about Linux with people who really knew their stuff. To support my learnings with practical application, I set-up and ran my own Linux server, and started my own professional blog, which I still run to this day.

Linux Professional Institute, LPI Exam Prep, LPI Preparation, LPI Guides, LPI Certification, LPI Tutorial and Material, LPI Learning, LPI Career
“The exams were actually much tougher and more thorough than I had expected, but that shows it’s something worthwhile. I’d recommend dedicating at least an hour a day to prepare for the exam.

“It took me approximately a year to complete all three exams (LPIC-1 [101 and 102] and Linux Essentials) but within a week of getting my first Linux certification, I got a job as a Support Technician, at Silicon Mechanics – where I currently work, but now as a Senior Support Technician.

My day-to-day work usually involves my using Linux in some way – so the certifications have helped me enormously. I’d definitely recommend it as a good foundation for anyone interested in an IT career – in fact, I have recommended it to colleagues who have also gone on to take the LPI exams.

For my own next step, LPIC-2 is on my list: I’m always looking to learn more about my industry and the LPIC-2 exam will allow me to take my knowledge to that next level – ultimately, enabling me to better support my customers.

Technology is always evolving, which makes it a fascinating industry to work in. We also now have an automation and DevOps team at Silicon Mechanics, and I’ll soon be joining up with that team and working with them on a number of projects. Once I take my LPIC-2 exam, I’m looking forward to taking the LPIC-OT: DevOps certification, so I can upskill in that area too.”

Open Education: The Many Ways to Target World Disparities

LPI Exam Prep, LPI Tutorial and Material, LPI Learning, LPI Preparation, LPI Guides, LPI Career

This month, the Open Anniversary initiative covers education. It's universally recognized that education is the basis for solving problems everywhere: poverty, the status of women, adaptation to environmental disruption, and more. Anything that can spread high-quality education—and nowadays, we must specifically call for accurate education—is therefore contributing to saving our world.

Education has many aspects, including teaching itself, stand-alone materials such as books and videos, and access to the internet or other media. We'll cover a variety of contributions to expanding education in this article.

Open Educational Resources

The most widespread and well-known phenomenon in open education is free course materials. The official term, Open Educational Resources (OER), was launched as an international movement by UNESCO in a 2012 declaration. The declaration was covered in an article by Creative Commons, which has a site devoted to OER. The Hewlett Foundation is another long-time backer of OER.

OER commonly offers a bundle of resources in many media to support the teaching of a single course. The materials may include documents, videos, suggested readings, and curricula. One of the oldest and largest such archives is OpenCourseWare at the Massachusetts Institute of Technology (MIT). The university started accumulating syllabuses, lecture notes, videos, and other materials from its professors in 2002, and now claims to serve millions of visitors every year.

One of the reasons OpenCourseWare makes a good case study, besides its size and longevity, is that MIT released a major study of its impact in 2005, followed by smaller annual reports since then.

One intriguing finding in the study is that many visitors redistribute the materials, in print or electronic form, to students who lack internet connections (page 8). We will see other projects in this article that tap educational materials online and bring them to people who can't get online themselves. This phenomenon illustrates how the internet intersects with other distribution media in the modern world.

What's truly significant about OER sites such as OpenCourseWare is the dynamic adaptation of materials made by professors and others. Anyone is free to modify and redistribute the materials, as with free software. The 2005 MIT study found that "62% combine OCW materials with other content; 38% adapt course syllabi; 26% adapt assignments or exams" (page 3). This means, for instance, that instructors and even students can add material of local interest. And they can do translations: in fact, MIT is cooperating with several institutions to do translations into several languages (page 7).

Despite the radically open approach to modifications, I've found that most OER sites prohibit noncommercial use. The free software movement generally wants commercial use to be allowed. One OER site that does permit commercial use is OpenStax, from Rice University.

MIT, as a science institution (with departments in economics, marketing, and some other topics as well) has an advantage in designing open source materials because their courses cover topics that have no geographic limitations. Other institutions, which may offer courses on history or policy-making in a single country, would find their courses to be of less interest on a world market.

LinuxTips is a training program in Brazil that focuses on populations who are under-represented in computing by race or gender. According to Cesar Brod, LPI's Community Engagement Director for Spanish and Portuguese Regions, 75 percent of LinuxTips students receive full scholarships. All of their learning materials are released cost-free. EDUCATRANSFORMA is another Brazilian project, friendly to transgender people, that offers bootcamps about Linux.

Many other institutions offer OER, including a large collection are Reynold Community College and some edX courses.

Educational Platforms

We turn next to open computer systems designed for educational use. These systems are based on GNU/Linux, both because the licensing allows widespread, free distribution and because the systems themselves are open. Teachers and students can fix bugs, make enhancements, and learn valuable software skills along the way.

Some of these distributions are more finely tuned for educational use than others. In general, they contain games, educational resources, useful tools for content creation, and sometimes tools for organizing and conducting classes. Many distributions are useful in homes as well as schools, and often other institutions.

A notable example of these efforts is SoDiLinux, a free-of-charge distribution of digital educational resources that can be used as a live USB/DVD or installed directly on a computer.  The name comes from "software didattico libero" (free educational software in Italian) and denotes an initiative designed for Italian schools. The project was initiated by the Institute for Educational Technology of the Italian National Research Council (CNR-ITD) and was initially funded in 2003 as a research project by AICA (Italian Association for Automated Calculation).

SoDiLinux offers a comprehensive range of educational apps and resources (both online and offline) supported by informative documentation from CNR-ITD’s educational resources database, Essediquadro. In addition, it provides several FLOSS assistive technologies (e.g., screen reader, magnifiers, on-screen keyboard) together with guides and tutorials about how to use them. SoDiLinux users can navigate learning resources by following specific themes (for instance, “Developing computational thinking”, “Producing interactive lessons”, or “Teaching how to use the web”), a feature that helps new users to find the resources they need more easily.

CNR-ITD continues to develop and maintain SoDiLinux; the latest version, “SoDiLinux Orizzonti (Horizons) 2025,” was published in February 2021.

Since 2007, a concerted effort has been made to render SoDiLinux more inclusive by adopting Universal Design principles. Italian teachers and students can now customize the environment to make it more suitable to their specific needs.

Some other distributions include:

EducatuX from Brazil. It is used in many public K-12 classrooms, being currently the only software package that contains all the materials required by the Ministry of Education for those classes.

◉ Endless OS. It includes a large collection of Wikipedia entries and educational materials, and is distributed to areas lacking internet access.

◉ Nova Linux from Cuba. This also is commonly used in schools.

◉ Escuelas Linux from Mexico. It is designed to be easy to use out of the box and contains a lot of educational apps.

◉ Huayra from Argentina. Its contents are fairly general, but it is promoted by the government of Argentina for use in all secondary education. According to Juan Ibarra, LPI's Partner Success Manager for Spanish and Portuguese Regions, the government has delivered more than 5 million netbooks with Huayra to students. The distribution has been reviewed in an English-language article.

◉ Guadalinex from Spain. It is used in education, along with other settings.

Learning Materials from Linux Professional Institute

The publisher of this article, Linux Professional Institute, has been developing an educational resource with important ramifications in free software: LPI Learning Materials. These cover a wide range of free and open source information required to pass LPI certification exams. Their organization matches the organization of the exams, topic by topic. Therefore, they are particularly apt for training programs.

Because Learning Materials are closely mapped to certification exams and LPI is concerned about maintaining quality for both the original English texts and the numerous translations, the license (CC BY-NC-ND 4.0)  does not allow derivative products (changes to the original). They appear in this article because of their free availability for private use and their role in opening up knowledge about free software in general.

Furthermore, Learning Materials are notable for being a communal effort, developed by experts around the world. (I have done some reviewing myself.) One contributor, Alejando Egea Abellan, said, "Together we create a cool, passionate and diverse community whose main goal is the creation of updated quality materials that can be used by [LPI] candidates living anywhere on the planet."

Even though the first Learning Materials appeared in 2019, they have made inroads into professional training sites as well as university programs. For instance, Franz Knipp teaches bachelor-level courses in the computer science program at the University of Applied Sciences, Burgenland, Austria. He makes heavy use of the LPI Learning Materials for Linux Essentials, and offers the certification exam at the end of the course. 

Peer-to-Peer Education

LPI Exam Prep, LPI Tutorial and Material, LPI Learning, LPI Preparation, LPI Guides, LPI Career
Another kind of openness consists of people coming together to learn without a teacher. This has been happening throughout human history, and among animals before it, so here we'll just look at a popular, highly organized process called Learning Circles, coordinated by a group known as Peer-to-Peer University (P2PU).

Learning Circles have traditionally been held in person. Libraries are typical meeting places.

Each class has a facilitator, who does not have to know the subject and who helps to keep the class moving along productively on-topic. At a library, the librarian may take on this role. The role of the facilitator is group dynamics, not teaching. The students mostly teach each other, but may invite a subject-matter expert occasionally. In addition to helping each other learn, students provide peer support for sticking to a plan. Their shared goal of learning a particular topic provides both structure and motivation.

Learning Circles are a powerful form of empowerment in isolated places without access to teachers in a particular subject. The curricula and materials are often designed by schools and offered free to participants in the program.

P2PU, based in Boston, Massachusetts, USA, runs courses using open source tools such as Moodle, a learning management system.

Top 5 Linux Certifications to Get in 2021

Best Linux Certifications are what you should aim for in 2021. Well, this is what the experts believe! But definitely, it might be a tough decision to make about choosing the right Linux certifications to boost up your career. Especially, the beginners, right? But, we here have simplified it for you. And, here is the list of those top 5 Linux certifications that you must go for in this year.

Top 5 Linux Certifications in 2021, LPI Exam Prep, LPI Tutorial and Material, LPI Certification, LPI Prep, LPI Learning, LPI Preparation, Linux Certification

1. LINUX+ CompTIA


It has almost been two decades that employers have used this certification as their skills benchmark for employing any professional in the IT world. And, so attaining this has become the utter need for every individual who is looking forward to entering into this area of IT.

CompTIA Linux+ is one of the Linux certifications that tests the essential usage and managerial tasks that are common to all Linux distributors. Yes, UNIX flavors need it too! So, to attain this Linux+ certification, you are ought to get through these two tests, which are CompTIA Linux Certification (LX0-103) and CompTIA Linux Certification (LX0-104), which actually shares the similar content to LPIC-1 (LPI Level 1 – Linux Administrator certification. Of course, this has to be done through any Linux Professional Institute to list yourself among all those who are actually eligible to enter into the field of Linux.

Let’s know more about these two Linux certifications here:

CompTIA Linux Certification (LX0-103) – Explained

This test covers these few domains, which are:

◉ GNU and UNIX Commands
◉ System Architecture
◉ Linux Installation and Package Management
◉ Devices, Linux Filesystems, Filesystem Hierarchy Standard

CompTIA Linux Certification (LX0-104) – Explained

This test covers these few domains, which are:

◉ Security
◉ Shells, Scripting, and Data Management
◉ User Interfaces and Desktops
◉ Administrative Tasks
◉ Essential System Services
◉ Networking Fundamentals

Both these tests have 60 MCQs, which needs to be done within a time limit of 90 minutes. The passing score is 500 on the scale of 200-800 and all questions are weight based. Both the tests are to be passed to get the certification.

Why should you go for these Linux Certifications?

These Linux Certifications are important for every Linux oriented professional because of these following reasons:

a) Brand Recognition – CompTIA Linux+ will give you brand recognition, which most of the HR departments and IT managers are already aware of. All of them know, if any certification in Linux is ending with a + sign, then that’s surely going to be a good skill benchmark for any IT professional. So, yes, brand recognition is something you will achieve after becoming a CompTIA Linux+ professional.

b) Foundation of all Linux Jobs - For almost every job that involves the word ‘Linux’, you can consider this certification as a foundation. As this certification edifies you about all the general administration tasks, which most of the organizations would generally seek, your chances of getting hired almost doubles. Basically, it allows you to gain knowledge of all the administration concepts and tasks, which are generally expected in any organization.

So, get yourself educated about CompTIA Linux+ seems to quite helpful in getting all those important tasks done in the Linux department.

2. RHCE- RED HAT CERTIFIED ENGINEER


In the dominion of Linux world and Linux certifications, there is another important certification called RHCE- Red Hat Certified Engineer. Red Hat Certifications really stand out amongst all the Linux certifications and surely it has the power to make you too stand out from the bunch of professionals as well.

Among all the Red Hat Certifications, Red Hat’s more senior-level certifications are quite popular. So, go for the senior-level ones for getting hired in those top organizations. And, in case you hold this certification, there are different roles in the Linux world which you may try for. Some of these job roles are senior Linux administrator, senior systems engineer, IT analyst, senior UNIX administrator, and the like.

How tough is it to attain this certification?

Well, if we believe those sitting at the top positions in the IT world, this is one of the best Linux certifications, which any Linux professional must go for. And, that’s why it is not easy to obtain. So, for becoming a Red Hat Certified Engineer, you must first obtain the Red Hat Certified System Administrator (RHCSA) credential, which is then followed by passing a three and a half hour test, hands-on, and an exam that is performance-based including both demanding and intense questions.

In case, you have earned RHCE, you become eligible for RHCA (Red Hat Certified Architect) credentials including:

◉ RHCA: Application development
◉ RHCA: Datacenter
◉ RHCA: Cloud
◉ RHCA: DevOps
◉ RHCA: Application platform

So, in short, if you are looking for a better position and payout in any IT organization, we recommend you to go for this certification in 2021.

3. GCUX: GIAC CERTIFIED UNIX SECURITY ADMINISTRATOR


GIAC Certified UNIX System Administrators secures and audit Linux and UNIX systems. It is one of the Linux certifications that is done to attain the skills and abilities to do so. The main motive of this certification is to train individuals in installing, configuring, and monitoring both these systems. So, like any other Linux certification test, this one too has a few requirements, which are as follows:

◉ 75 questions
◉ 1 proctored exam
◉ Time Limit- 2 hours
◉ Minimum passing score of 68%

Basically, the candidate understands the physical security issues and password security with respect to both the UNIX and Linux systems. This exam even tests the capability of the candidate to understand Chroot- how to configure its services, its environment, how to configure scponly with chroot, and everything else about Chroot. Apart from this, some others areas of the UNIX and Linux are also touched including OS Install and Patching, Physical, User Account, and Password Access Control, Boot Services, Post-Exploitation and AIDE, SUDO, and many other important sections, without which UNIX and Linux, both are incomplete.

Being a part of SANS, this Linux certification is highly recommended to every Linux professional in 2021.  It encompasses more than 35 security certifications across different categories, which we mentioned above. Such an administrator falls under the Cyber Defense category. Also, their certifications need renewal after every four hours by earning 36 continuing professional experience which is also known as CPE.

4. ORACLE LINUX OCA & OCP


This Linux certification is all about attaining skills and abilities related to Oracle products and technologies. For passing the test to get the certification, the professional needs to pass the combination of passing exams and training and performance-based assignments, which depend on the level of certification.

With 6 levels of Oracle Certification Credentials- Oracle Certified Junior Associate (OJA), Oracle Certified Associate (OCA), Oracle Certified Professional (OCP), Oracle Certified Master (OCM), Oracle Certified Expert (OCE) and Oracle Certified Specialist (OCS), a candidate needs to master all such stages to be hired by a reputed IT company.

Certifications comprise of two exams, which are:

◉ OCA - 1Z0-100 Oracle Linux 5 and 6 System Administration, needs 61% to pass, and 80 questions to attempt

◉ OCP - 1Z0-105 Oracle Linux 6 Advanced System Administrator, requires 61% to pass, and has a total of 97 questions.

5. LPI (LINUX PROFESSIONAL INSTITUTE) CERTIFICATIONS


Started back in 1999 by Linus Torvalds, these Linux certifications today has become important for any Linux professional. This program is available in three distinct levels, which are:


It is a junior-level Linux certification with no perquisites. The candidate needs to pass 2 exams, which covers all basic Linux skills that even include installing and configuring Linux on a workstation, performing maintenance tasks, making LAN or internet connections, and more. Obtain CompTIA Linux+ powered by LPI credential first; which will make you qualified both for Linux+ and LPIC-1 credentials.


This is an advanced level Linux Certification, which requires an active LPIC-1 certification. It has two exams- First covers the file system and devices, kernel, system startup, network configuration, system maintenance, storage administration, and even capacity planning and the second exam covers email services, network client management, domain name servers, system security and troubleshooting, and the like tasks.


It is a senior-level Linux certification, which needs an active LPIC-2 besides passing any single exam in the 300 series. This certification includes exam IDs, which are:

◉ 300: Mixed Environment
◉ 303: Security

Linux Professional Institute (LPI) launched the Learning Portal in June 2019. The Learning Portal is the repository of all the Learning Materials for our exams. The whole project is managed by Dr. Markus Wirtz, manager Education Programs at LPI. We designed it as an international endeavour - learning is easier in your mother tongue! - hence we needed a team of authors, editors, and translators to design, write, and localize the body of lessons.

This series of interviews is a journey toward knowing better the People behind the Portal: the Linux and Open Source enthusiastic professionals who are making the Learning Portal possible.

By reading this series of interviews, you will know more about Contributors’ work, the peculiarities of translating IT educational material, and the challenges Contributors have to face restoring what could be lost in translation. And about why working on the Learning Portal is quite cool and nerdy. 

What is your academic and professional background?

I think many folk feel that they need a computer science degree to even make the tea in an IT department today. For me, I left school when I was 16 and certainly have never attended any university as a student. For many years I have been involved in IT training and have been freelancing for the past 8 years. In addition, I teach live online courses, offering well over 40 courses on Pluralsight.com, and I do very well from Linux and its associated ecosystem.

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

Teaching many vendor-based Linux courses, I had become frustrated with both the technical detail (or lack thereof) in the courses and how closed they were. I started creating YouTube videos in 2009 to make extra demonstrations more accessible in my classes. This was the start of my open education and continues today with well over 1000 videos on my channel and 66K subscribers.

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

I have also assisted the LPI in their open education portal with content for the Linux Essentials exam, one of the most important certifications to prove the credentials of the holder who has started their Linux journey.

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 those people who are studying for their LPI Exams?

If you are studying for the LPI exams, or for that matter, any IT exam, you must know the subject. Not just the bullet points but the details. Yes, I am telling you to read the man pages!. Be familiar with the commands and the how and the why they are used. Never underestimate the value in learning and practice. Your learning is the best investment that you can ever make in your career.

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?

Developing content for open source projects, including Linux, can be your pathway to paying your debt back to the open source community that creates the code and applications that you use. We are all happy to use Linux as a free OS and even tools like Microsoft's Visual Studio code. As educators, we can create content to promote these products and their benefits.

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?

I can confirm that the LPI will not welcome your contributions in a Word document format— strange that! The workflow for creating content for LPI, and many other similar organizations, is likely to require you to learn Markdown or AsciiDoc. These are simple markup languages that you may use in any text editor. It is really simple to use. Its simplicity and flexibility helps you understand why it is used on open source projects in Github and in the ReadMe.MD file that is always present.
