Exam Preparation with the LPI Learning Materials

The Linux Professional Institute (LPI) started its Learning initiative in 2019 by publishing the first Learning Materials on learning.lpi.org. As a supplement to specialist books from publishers or other platforms, the Learning Materials are designed for intensive preparation for their respective LPI exams. The Learning Materials for each exam are organized around the same categories as that exam and cover the relevant topics. These topics are published on the LPI wiki.

Objectives and Lessons

Let’s take a look at how the Learning Materials are structured and how to get the most benefit from exam preparation.

The Learning Materials follow exactly the topics and objectives of each exam. Each objective is dealt with in one to three lessons, depending on its weight in the exam. For example, consider objective 3.3, “Turning Commands into a Script,” of the Linux Essentials exam. The web site lists the objective as shown in Figure 1.

Figure 1: Objective listing has a weight of 4.

The weight given is 4, which means that 4 of the 40 exam questions are dedicated to this objective. In the Learning Materials: 2 points in weight correspond to one lesson. Therefore, an objective weighted with 4 is treated accordingly in 2 lessons, as shown at the bottom of Figure 2.

Figure 2. Objective 3.3 consists of two lessons.

Lesson Structure

All lessons have the same structure.

The Introduction lays out the areas of knowledge specified for the objective and explains the respective technologies, terms, and tools with clear practical examples (Figure 3). Background knowledge is assumed, so the explanations are limited to the required knowledge without repeating the necessary prerequisites.

The Introduction is followed by two sections with exercises. Guided Exercises consolidate the previously summarized knowledge and can be solved after carefully reading the Introduction. The subsequent Explorational Exercises go a step further and may require additional research, such as looking for options or arguments for a specific command on the command line that were not mentioned in the Introduction.

After a short Summary, the two exercise blocks follow again, but this time with the correct solutions.

Figure 3. Beginning of the Introduction to a lesson.

For Classes and Self-study

Why this particular structure? Who can make best use of the Learning Materials, and how?

Teachers and trainers usually organize their teaching load in lessons, so each lesson in the Learning Materials is designed for 45-90 minutes of instruction, depending on the level of knowledge of the students. The content is prepared in such a way that the teacher either presents it or reads and develops it together with the students in the class. For example, inputs and outputs on the command line are selected and summarized so that they can be understood when reading, even without computer workstations in class.

The exercises, which can either be addressed in class or assigned as homework and then compared with the solutions, are also of great advantage.

The clear structure of the lessons, as well as the focus of the Learning Materials to the objectives, allow very precise planning of the curriculum. The Learning Materials are thus a useful, out-of-the-box resource, especially for teachers who often have little time for lesson preparation.

The second group of recipients are all those who prepare for the exam through self-study. The availability of the Learning Materials online, in HTML or as a PDF for download, offers great flexibility in preparation.

Here too, the three-step “learn – test – check” process has proven successful. And since the lessons are self-contained units, candidates need to work only on the topics with which they are unfamiliar, perhaps because these skills are not so relevant in their daily work, to close their gaps in knowledge. So students can focus on the lessons about topics in which they don’t yet feel confident.

One strategy for self-study is to take a look at the exercises (without solutions) and check how confident you are of the answer. If there are any doubts, read the Introduction and then try again.

Languages and Formats

Learning is easiest in your own language. That’s why the Learning Materials are already available in numerous translations – and more are constantly being added.

And last but not least: The LPI Learning Materials are freely available for non-commercial use! Teachers, trainers, and students are cordially invited to use or download them at learning.lpi.org. For commercial use–for example as teaching material in a paid course–the course providers have the opportunity to brand and use the Learning Materials with their own company logo as an LPI Training Partner.

So let’s summarize the main features of LPI Learning Materials:

• Cover all topics relevant to the exam
• Classroom-ready structure
• In class or for self-study
• Available in many languages
• Ongoing updates and corrections
• Free of charge for non-commercial use
• Co-branded PDFs for LPI Training Partners

Have fun preparing with the LPI Learning Materials and good luck with the exams!

Mastering LPI WDE: Materials, Practice, Simulations

In the previous articles of this series, we have examined the leading technologies covered by the Web Development Essentials certificate from Linux Professional Institute (LPI), both on the front-end side (such as HTML, CSS, and JavaScript) and on the back-end side (such as Node.js and SQL).

As we have seen, you can use HTML to structure your web pages semantically, CSS to apply styles and make them visually appealing, JavaScript to enable user interaction and add dynamism, Node.js to implement server-side logic, and SQL to query a relational database.

At this point, you may wonder, “How can I prepare for the WDE exam? Are there any reference materials? How can I simulate the exam?” This article will answer these and other questions.

How can I prepare for the LPI’s WDE certificate exam?

LPI’s Learning Materials are your initial reference point. The Linux Professional Institute (LPI) Learning Portal is the natural starting point for your learning journey and preparation for Linux and Open Source certification exams.

Each section of the Learning Materials has a well-delineated structure: a theory part and two sets of exercises with their solutions, following an approach oriented toward classroom use. These materials are continuously expanded and updated and are of great utility for both students and teachers.

Therefore, to prepare for the Web Development Essentials certificate, I recommend starting with the Learning Materials specifically written for that certificate.

You will find the exam objectives updated to the current version (exam code 030-100) and, for each Objective, one or more lessons depending on their scope and weight.

Each lesson, designed for one or two hours of frontal teaching, includes a theoretical part and a practical part where a student can immediately test the acquired knowledge in practice. Finally, the solutions to the proposed questions will allow you to check whether your exercises are correct and, in most cases, provide additional insights for further study.

The enormous potential of this educational material should be apparent: It is not only a free resource available to anyone who wants to delve into the world of programming but also a valid reference for those who, at the end of their studies, want to embark on the certification path itself.

Remember that, like all Learning Materials, those related to the Web Development Essentials certificate do not replace textbooks or practice and should complement other study sources.

And for practice?

Once you have learned the main exam topics from a theoretical perspective, it is necessary to practice–in fact, practice a lot… You can refine your skills and improve your web developer knowledge by practicing in the field. As discussed in the first post on HTML, you can start practicing by creating web pages using one of the text editors already on your computer, and then move on to slightly more sophisticated ones that I have suggested here or to a full-fledged IDE environment. Discovering all the features of these programs can be a professionally rewarding experience. You can improve your productivity by becoming a more efficient programmer during your learning journey.

Here are some other resources I recommend:

◉ Mozilla Developer Network: An accurate wiki available to all developers. It is ideal for beginners and, at the same time, an excellent tool for those who are already more experienced and want to improve their skills.

◉ Free Code Camp: A non-profit community that allows you to learn programming by completing real projects. You can learn to program through their learning platform, read publications, discuss questions on the technology forum, and much more.

Web Development Essentials Exam simulations

The Web Development Essentials certificate allows you to take the first steps in the web world. At the end of the path, you will need to take an exam that, like all essential certificates, consists of 40 questions over a period of 60 minutes.

To simulate the actual exam, I have published, as an LPI Publishing Partner, a resource called Web Development Essentials Practice Exams. It is a book of simulations that allows you to test your knowledge and skills before taking the exam.

The book contains four exam simulations and an entry test, totalling 170 questions and answers. Each question is accompanied by thorough comments to show the student the correct answer as well as the general context it refers to.

Some questions include code snippets you can reproduce in your text editor to find the correct answer. Furthermore, by trying to modify this code, you can create alternative scenarios that are useful for your learning.

Just the beginning

Remember that passing the exam does not make you an expert programmer. The exam is the starting point, not the destination.

Good developers must refine their knowledge daily and keep up with the times. You will need to learn new libraries, frameworks, and programming languages and, above all, put a lot of passion into it. This passion must be nurtured daily to improve yourself professionally.

Above all, you must love what you do because, as Confucius said:

Choose a job you love and you’ll never have to work a day in your life.

The Linux Advantage: Why Free Software Underlies Modern Computing

Free and open source software (FOSS) is ubiquitous nowadays, with the GNU/Linux operating system making particularly big strides. This article makes some observations and speculations about the reasons that FOSS is increasingly preferred over proprietary systems such as Windows.

A few statistics to establish the situation I’ll be commenting on:

• Android (based on Linux) has surpassed Windows as the world’s most popular operating system as of April 2023. This achievement is attributed to the popularity of mobile devices, although Windows still dominates desktop and laptop systems. Android itself is open source, although Google strictly controls development for Google-based mobile devices.
• Linux is also the most popular guest operating system in the cloud. (Cloud hardware runs host operating systems, on which clients run their systems as guests.) Four years ago, tech journalist Steven Vaughan-Nichols reported that even Microsoft’s own Azure cloud service was running more Linux guests than Windows guests.
• The embedded space is even more lopsided. Here, Windows and macOS systems are not even considered because of their heavy desktop-suited footprints. For embedded systems, Linux competes with a few dedicated embedded operating systems, many of which are also open source.
• Vaughan-Nichols also reports that by 2015, 96.3% of the top one million web servers were running Linux.
• All of the world’s top 500 supercomputers run Linux.

Therefore, the spread of Linux is truly impressive. It rules the smallest footprints (embedded systems, although Linux demands more resources than some dedicated embedded operating systems) and the largest (supercomputers). Now let’s think about why.

Operating systems are complex nuts to crack

A modern operating system has a lot to do, and the conflicting demands on it make it one of the most complex pieces of software we have.

Ideally, the system would handle small jobs quickly while allowing big, batch jobs to run without interruption. The system would recognize different types of hardware interrupts and react quickly to interrupts that call for a fast response, whether they’re user keyclicks or alerts from overheating factory equipment.

The system must direct inputs from tens or thousands of network connections to the right processes, which may start up and shut down unexpectedly. It must juggle four, eight, or more hardware cores, figuring out when to replace a process with another and clear the cache.

As operating systems get older, they have to deal with the legacies of earlier versions. For instance, Microsoft’s NT version of Windows (at least for a time) had to handle programs written to an obsolete Intel architecture. In the case of Linux, developers have to honor POSIX standards and maintain many old system calls from Unix and BSD.

I could go on, but instead I’ll direct you to sites such as LWN.net that discuss kernel development in mind-numbing detail.

Linux is an unusually tunable operating system. Administrators don’t have to alter its code (although they could, of course, because it’s free software); instead they can set hundreds of configuration variables to alter the kinds of parameters, and remove services and libraries to improve security and reduce the operating systems’ footprint. This flexibility endears Linux to administrators of data centers.

There’s no money in operating systems anymore, largely because of the success of Linux. So Apple, Microsoft, and all the companies that used to market their own versions of Unix (a few still do) would love to save their money for sexier investments, which nowadays include generative AI, cloud offerings, quantum computing, collaboration, and security.

Apple has already taken advantage of the open source dividend, by basing their proprietary operating systems for both macOS and iOS on versions of the BSD operating system. Microsoft is sticking with Windows for now, but contributes enormous amounts of money and research time to Linux.

True, Windows is still the most popular operating system on personal computers, but most desktop and laptop applications run over the web. As we’ve seen, the most popular operating system for mobile devices is the Linux-based Android.

Many observers predict that the time is not far off when supporting Windows will be too expensive for Microsoft to find it worthwhile. The leading minds at Microsoft focus more on cloud offerings, refining AI for their Bing search engine, and supporting professional collaboration with applications that revolve around Microsoft Teams.

Get ahead of the starting line as a developer

The days are fading when Windows was the system to develop on first and foremost. As mentioned in the previous section, developers will continue to target Windows for applications that run natively on PCs. But in the areas of greatest growth—web, mobile, commercial, scientific, and embedded development—you’ll generally find GNU/Linux.

On the Web, you worry very little about the operating system (in fact, you have to abstract away from the OS as much as you can). The JavaScript and PHP languages take up your attention.

For mobile devices, you concentrate on Kotlin for Android (perhaps with some attention to old Java programs) and on Swift for iOS.

Embedded systems also often run on Linux, because it can be stripped down to a lightweight kernel with minimal supporting libraries and programs. Devices for which Linux is still too heavyweight use a variety of competing operating systems developed specifically for embedded use.

Commercial and scientific applications run in data centers that, as we have seen, increasingly run on Linux. Python is the preferred programming language in science.

The developers who work on tools and applications for managing data centers are familiar with Linux, and often run Linux on their personal systems so that they can switch smoothly between their personal environment and the corporate data center. There is even progress on providing video games for Linux, partly supported by the Linux-based SteamOS operating system.

Thus, popular tools and languages are developed on Linux and then ported to other operating systems. It follows that these operating systems lag behind Linux in supporting new versions and getting bug fixes.

Developers also tend to like Apple computers, and some use Windows PCs. But Apples and Windows systems introduce an extra level of friction when trying to develop programs for commercial or scientific purposes, because the target operating system is likely to be Linux.

No struggle with licenses

Proprietary operating systems include a great deal of technical and logistical overhead to ensure that the operating system vendor gets paid. This overhead is a drag on system use, from installation through long-term maintenance. Vendors nowadays have special licensing for virtual machines, but these still add cost and overhead.

I won’t focus here on the cost of licensing a proprietary operating system, because it is a small part of most computing expenses and because companies who use open source software still have associated expenses such as support. In other words, free software is not cost-free. So I’ll focus instead on the logistical burden of proprietary licenses.

Anyone who has installed proprietary software on their personal systems knows the frustration of entering twenty or thirty random characters to assure the installation process that they have a valid license.

When you want to install a new version of the software or re-install the software on a new computer, you might have to twist yourself into contortions to remove the old version or make sure only one version is running at a time.

Institutions with group licenses have to run a dedicated licensing server to monitor all the systems (a potential risk to privacy and corporate secrets) and ensure that staff use of the software matches what the license allows.

In short, proprietary software creates a pain in a sensitive part of the body for users and administrators, above and beyond the educational and logistical requirements of the software itself.

Linux, in contrast, makes it easy to scale up and down, add new users or systems, and orchestrate the start-up and shut-down of virtual systems. The lack of intrusive licensing makes it the first choice for data centers.

The advantages of Linux make it more attractive over time

In this article, I’ve touched on many trends in modern computing: cloud offerings, expanded data centers, the move of applications to the Web or to mobile and embedded devices, and more. All these trends reduce the appeal of proprietary operating systems over time and increase the appeal of Linux.

Although the progress of GNU/Linux on the desktop is slow, the dominance of this operating system in other contexts will drive developers to use Linux and write applications for it, more and more. If you work for a large company with a data center or infrastructure in the cloud, it’s already in your interest to become familiar with Linux. Even if you’re an individual computer user, this is also a good time to take a look at it.

Edutech Europe, Amsterdam, 2023: My Takeout

Amsterdam’s Edutech Europe 2023 was a whirlwind of innovation, collaboration, and insights into the world of education technology. The purpose of this conference is to promote dialogue and collaboration between educators and computer developers who aim products at education.

Over the course of the event, I had the privilege of attending several talks and panels, each more enlightening than the previous one. The convergence of minds from various educational spheres made this conference an invaluable networking opportunity, and I couldn’t help but feel inspired by the visionaries shaping the future of learning.

Fostering Shared Understandings

Sibylle Harth, Director of Technology at the International School of Düsseldorf, touched upon the importance of bridging the gap between schools and parents. The rapidly evolving landscape of technologies such as AI and quantum computing necessitates a combined effort. To truly embrace the opportunities and navigate the challenges of such advancements, a shared understanding and collaborative effort between educators and parents are vital.

Redefining Learning Experiences

In another enriching panel, experts from iSpring Solutions, Heart Of Worcestershire College, and the Technological University of the Shannon: Midlands Midwest, among others, deliberated on the potential of hybrid learning. The emphasis on reliable IT networks and engaging teaching methodologies emphasized the significance of a seamless learning journey.

Pedtech: The Future of Learning

A particularly engaging discussion centered on the ‘pedtech revolution.’ The panelists, including Al Kingsley from NetSupport Limited and Laurie Forcier from the International Society for Technology in Education (ISTE), shed light on the importance of integrating pedagogical values when deciding on emerging technologies.

… What About FOSS?

Being at EduTech Europe with my LPI hat, I hope that the importance and potential of free and open source software are recognized more with each subsequent edition of events like Edutech Europe. The limitless possibilities of open-source solutions in the education sector remain vast, and I eagerly await the day when they are integral to every educational institution’s tech arsenal.

After all, while Microsoft was, along with Lego, Title Sponsor of this edition, Microsoft itself is also giving tutorials about how to install Linux, which induces feelings in me somewhere between amusement and incredulity.

Until the next edition, I remain hopeful and inspired, looking forward to more groundbreaking innovations in the world of education technology.
