LPI, LPIC-3 Security Certification, LPIC-3 Exam Prep, LPIC-3 Career, LPIC-3 Skills, LPIC-3 Jobs, LPIC-3 Prep, LPIC-3 News, LPIC-3

The Linux Professional Institute (LPI) recently released version 3.0 of the LPIC-3 certification, LPIC-3 Security, which includes some changes to the exam objectives. This release is part of a major update to the LPIC-3 certification program. The LPIC-3 certification series is the highest level offered by LPI and covers advanced open source topics in organizational computing infrastructure.

The new version of the exam updates several learning objectives to keep up with current technological changes. "In addition to the usual updates, new content has been added to the exam. The certification now includes managing the resource usage of individual applications. A new topic has also been added, 'Threats and Vulnerability Assessment', in which the exam takers can improve their understanding of common security threats and the ability to confirm the effectiveness of their security measures," says Fabian Thorns, Director of Product Development at LPI.

The overall scope of the exam content has not changed, as Thorns explains: "In version 3.0, the objectives related to FreeIPA, user authentication and NFS have been moved to the LPIC-3 Mixed Environment certification. These aspects are closely related to the topic of heterogeneous systems and fit perfect for Mixed Environments certification."

"LPIC-3 Security certified professionals are not only able to strengthen and defend Linux systems. They also have an in-depth knowledge of technologies such as X.509 certificates, DNSSEC and Virtual Private Networks, which are native to any type of operating system The practical experience in these technologies that we test and certify ensures that our graduates can both implement security measures in Linux and support colleagues from different backgrounds in practical aspects of IT security," adds LPI's Executive Director, G Matthew Rice, added.

The LPIC-3 Security Version 3.0 exams have been available since Monday, September 27, 2021 at the Pearson VUE test centers and on the OnVUE online testing platform, initially in English. A Japanese translation will be available shortly. The exam objectives can be found on the LPIC-3 overview page.

In 2021 all LPIC-3 certifications will be updated to version 3.0.

Recap and Survey on Our Interns’ NFT Project

LPI Career, LPI Preparation, LPI Careers, LPI Learning, LPI Tutorial and Materials, LPI Study, LPI Preparation Exam

Now that the fervor over NFTs is cooling down (or maybe not), this seems like a good time to close off our intern’s recent project.

Over the last summer, a couple of our interns worked on a small exploratory project in order to learn about blockchains, cryptocurrencies, and NFTs specifically. We wanted something that both the IT and marketing interns would find interesting and, for their group project, they decided on creating a Tux variation on the CryptoPunks series of NFTs from scratch. You can read more about what our interns did in their blogs here and here

At this point, the learning portion of the project is over for the interns but there has been some interest in minting NFTs of the artwork that they created and distributing them in some way that supports LPI’s mission to help foster the adoption of open source. Thus, there is a link to a survey at the end of this article where you, the reader, can add your opinion to the idea of continuing the project.

Why don’t we have consensus on whether to continue this project? Well, the project was interesting and relatively straight-forward to implement at the level of Solidity programming. However, during the project, it became apparent that some people have concerns around the use and viability of cryptocurrencies and NFTs as a technology.

The topmost concerns are that current public blockchain projects are resource intensive (look up the term Proof of Work for some more details on this topic) and can be difficult to make use of by less technically-oriented people. This situation reminds me of the early days of the X Window System and PostScript; slow performance-wise and expensive to implement but with a lot of potential and interesting features. Eventually, hardware and software caught up with X and PS and they’re ubiquitous technologies now.

There are other concerns that people have over the growing use of public blockchains which a reddit user does an excellent job of enumerating in a response to “What’s up with the NFT hate?”. You can read the list of issues in the post’s comments here. I won’t comment on all of them, though. Instead, I’ll focus on the major issues related to our project itself.

People are working on solutions to these problems but they aren’t completely solved yet. For example, the ecological impact of some of the major blockchains is being addressed by switching from Proof of Work to Proof of Stake (PoS) for their consensus mechanism. This should have a great impact on both the hardware and electricity requirements of maintaining a blockchain. Ethereum, the blockchain we used for our project, is expected to complete its transition to PoS sometime this year. In the meantime, many solutions are being developed “off-chain” through the use of layer-2 solutions built on top of the major layer-1 blockchains like Ethereum and Bitcoin. The move to PoS and continued use of layer-2 side-chains are helping to reduce the overall cost of transactions.

Mostly specific to NFTs is the issue of copyright and ownership of the underlying artwork. As Laravel Labs found with their CryptoPunks artwork, they overlooked how to handle the transfer of ownership of their artwork and retrofitted an “NFT license” for owners of the CryptoPunks NFT Short version: People own their NFTs but not the underlying artwork. This solution didn’t appeal to everyone but there are some groups working on the copyright transfer problem. As an example, Alibaba has launched an NFT marketplace that’s using “distributed ledger technology” in order to track and protect copyright claims and transfers.

Then there’s the grifting and fraud that is rampant in the industry. Enough so, that people are writing guides on how to avoid getting scammed by NFT creators and insecure marketplaces. These guides may help but there are also projects underway to make using crypto and owning NFTs easier and less prone to loss. Loopring’s counterfactual wallets and GameStop’s pending NFT marketplace are two examples of attempts to increase the user-friendliness of the technology.

One last concern that I want to mention is the “blockchains are a solution looking for a problem” tenet that some people espouse. I believe the same was said about X and PostScript when they first arrived on the scene (and C++ and HTML and Personal Computers…). With the overwhelming attention paid to NFT sales of cute and colorful cats and apes, it’s easy to think that this is all there is to NFTs and cryptocurrencies. However, there are lots of solutions to real world problems being built on top of blockchain technology. It’s just going to take some time, as well as some major flops and successes, for developers to learn when a publicly viewable linked list with a checksum database helps and when it doesn’t.

Overall, this project was a great success inside LPI. It prompted a lot of discussion about the technology and whether continuing the project is something that’s worthwhile. We didn’t come to a unanimous consensus, though. Some of us want to close off this project and move on to something else to learn. Some of us think that the fun part isn’t over and that we should publish the artwork, complete the NFT contract, mint the NFTs and distribute them amongst our community members.

What we did agree on was that we should ask the LPI community what they think about continuing or ending this project. If you’d like to share your opinion, here’s a short survey which asks for your thoughts overall and on how to handle decisions about the cost of minting NFTs, how to deal with copyright ownership of the artwork, how to share the NFTs, and other concerns.

LPI at WorldSkills Germany: Amazing Young IT Talents

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

WorldSkills, the world championship of professions, looks for outstanding talents in different job profiles each year. Since 2017, Linux Professional Institute (LPI) has supported WorldSkills Germany in Skill 39, IT-Network Systems Administration with exam tasks for the Linux sector. Last week, the German Championships took place in Kassel and we were excited to be there. The wonderful young IT talents really impressed us.

Twelve candidates had made it to the finals of the German Championships and competed against each other at the ECKD Event and Conference Center in Kassel. In front of a large audience and under time pressure, they had to organize complex information and telecommunications technology systems in Cisco, Microsoft, and Linux environments. And although they were all competing against each other, they grew together as a team during the championships.

"That is what WorldSkills is all about," said Hubert Romer, head of WorldSkills Germany. It is about promoting young talents worldwide and having them compete against each other on a globally consistent level. However, networks and friendships are also built in the process. "Once the WorldSkills fire has been lit, it never lets go," said Romer.

Linux Professional Institute was represented by Reiner Brandt, at the same time head of the IT Network North Hesse, which had brought the WorldSkills to Kassel. As LPI Channel Partner, his company Open Source Certification GmbH had helped to develop the examination tasks for the Linux part of WorldSkills, as in previous years. "It is always a great pleasure for us to be involved here and we look forward to supporting WorldSkills in the years to come," said Reiner Brandt.

Florian Zimmer won the competition in Kassel ahead of Eren Ahmet Koyuncu, Julian Jäger, Sebastian Plötz, and Jan Samuel Nichau. The five young men will be part of the German national team in Skill 39 and represent their country at the European and World Championships.

The WorldSkills German Championships in Kassel were organized by IT-Netzwerk e.V. and Regionalmanagement Nordhessen and supported by the sponsors ECKD, CISCO, Computacenter, IHK Kassel-Marburg, quindata, Linux Professional Institute, Techniker Krankenkasse, MultiMediaBerufsbildende Schulen, and IT-Bildungsnetz e.V.
