News story #1: Agile after 20 years

With the manifesto for Agile software development turning 20 this year, industry insiders are looking back at the philosophy’s two decades of existence to see how deeply embedded it actually is among the world’s businesses. 

While most companies have fully bought into the idea of Agile and are on board with its values and principles, the term “agile” is still a buzzword rather than a true practice in many cases. 

According to experts, organisations often resort to Agile methodologies as a simple solution to accelerate their digital transformation projects. In doing so, they fail to implement the development framework as a wholistic philosophy that ties IT with business objectives.

Automated testing and deployment and rapid feedback loops have been widely adopted by industry players, but better value stream mapping and new business-oriented performance metrics will be needed if we are to unleash the full potential of Agile.

News story #2: Berners-Lee’s annual letter

Just like Warren Buffett, Tim Berners-Lee (a.k.a. the father of the world wide web) has made a habit out of sending an annual letter reflecting on the state of the Internet world.

Last Friday, March 12th, marked the 30th anniversary of the web, and Berners-Lee, who has always been adamant about making the Internet a more inclusive medium, turned his attention to universal access to the Internet, web-based environmental initiatives and curbing online abuse. According to Berners-Lee, the pandemic has accentuated the difference between the 2.2 billion young people who lack stable Internet access and those who don’t. But it is the web’s hostility towards minorities that worries him the most.

Yet, despite his concerns regarding “the toxic Internet,” Berners-lee is optimistic about our ability to make online forums a safer place. Specifically, he points towards big social media platforms as the ones who should be implementing the changes to make that happen. The way forward, says Berners-Lee, should be building “social networks where bad things happen less.”

News story #3: Mirror-based computers

The end the week in IT news — While quantum computing is the alternative to traditional computers that gets the most attention these days, it is not the only new kid in the block. 

Researchers are also exploring ways to make standard bit-based computation faster and more efficient — and we are not talking about cramming more transistors into a silicon chip. It’s more about re-inventing the traditional transistor altogether. After all, we don’t need all future computers to be quantum; faster traditional PCs should suffice for most tasks. Enter light-based computing.

University of Cambridge researchers have discovered a way of making a material switch between glass and mirror with a short laser pulse. This type of optical switching is way faster than current computer switches — about a million times faster. It also consumes a fraction of the energy. Plus, the switch could be applied to quantum computing as well.

IT Infrastructure Job Descriptions

Linux Systems Engineer : Job Description

Use our template to create a compelling and comprehensive Linux Systems Engineer job description to attract top talent.

Unlike Windows or macOS, Linux is an open-source operating system that is free and accessible to all. That is, any user can run, modify, and share Linux code. Its open-source nature is a big advantage over traditional operating systems which are locked down, proprietary, and unmodifiable. Linux also has the advantage of being more secure and having fewer security holes than traditional systems.

More and more, large companies are using computers running Linux. Accordingly, the Linux System Engineer function is on the rise. The Linux System Engineer is an essential link within companies that ensures the proper functioning of a Linux network. The engineer helps coordinate the IT team, optimises network operations and ensures communication between the various information systems.


Also explore the role of the Android Developer

What is the role of the Linux Systems Engineer?

The missions revolve around two main areas:

“Build” project activities

The Linux Systems Engineer is primarily in charge of what are called project or “build” activities. That is to say everything related to technical advice, expertise and innovation. The role is to advise CIOs on the use and configuration of technical solutions in Linux.

This professional is also responsible for supporting the implementation of new solutions under this operating system. They also contribute to the technical validation phase and must implement means to guarantee the high quality and availability of the service. This professional must also keep an eye on all new developments regarding Linux to optimise system resources and continuously improve the operating system.

“Run” production activities

The Linux System Engineer is also responsible for intervening in production activities, which is called the “run”. That is to say the maintenance of the operating system, administrating it and maintaining it operational. The engineer must ensure that the entire system is functional and usable. They must also take care of the day-to-day administration as well as measure and optimise system performance. But they also provide preventive, corrective and evolutionary maintenance of the Linux systems of the company. To finish, they are responsible for managing incidents by ensuring the diagnosis and repair of any malfunctions. The Linux Systems Engineer is also responsible for testing the system, ensuring its security and reliability, and managing the user support side of things.

Linux Systems E can specialise in either project activities or in production activities. But, generally, these professionals work in both types of activities. A good Linux Systems engineer will be able to work on both project and production activities.

Required skills

Very good technical mastery

The Linux Systems Engineer should have very good knowledge of the Linux operating system and expertise in technical infrastructure software. They must have an in-depth knowledge of Linux system layers as well as a good knowledge of Linux installation processes. They must also often master programming languages, including Python, and also know Scripting (Patch or PowerShell). The Linux Systems Engineer should also have good knowledge of databases and security standards.

Solid professional skills

The Linux Systems Engineer must be rigorous, organised and methodical, as their missions require compliance with quality processes and rules. They must have great capacity for anticipation, initiative, technical curiosity and adaptability to ensure effective technical monitoring and adapt quickly to new technological developments. It is also important that this professional has good analytical skills, resistance to stress and reactivity. So they can deal with breakdowns or technical incidents. They also need to be versatile and have good interpersonal skills to maintain good relationships with other stakeholders.

Salary of the Linux Systems Engineer

The average daily rate a Linux Systems Engineer ranges between €200 and €600. Their median salary sits between 30K and 60K per year.

Training of the Linux Systems Engineer

To become a Linux Systems Engineer a university-level degree is required. That is to say, you generally need to have an engineering degree or a master’s degree specializing in computer science.

Several universities offer specialisations in operating systems. Engineering schools often offer specialties at the end of the course or have specialized courses. You can also take a Masters in computer science specialising in networks and systems ; or an engineering degree specialising in computer science.

Weekly News: How Tech Is Rewiring our Brains

How Tech is rewiring our brains, a few bumps on the road for data science, new AI beats historic videogame trap; and the newest new Internet… Discover our weekly news about Tech & IT.

How Tech Is Rewiring our Brains – ‘We shape our tools, and thereafter our tools shape us.’

How Tech is rewiring our brains?

‘We shape our tools, and thereafter our tools shape us.’ Often mistakenly attributed to the philosopher Marshall McLuhan, this quote by John Culkin has become a symbol of the symbiotic relationship between humans and tech. 

Science writer Nicholas Carr took the concept to a new level in his 2010 book The Shallows: What the Internet Is Doing to our Brains. It was not that well-received at the time. But with every new app that changes the way we communicate and consume information, it gets clearer how relevant Carr’s work was and remains. 

In the book, Carr leaves moral judgements aside and urges us to approach technology from a position of understanding. 

Our brain is being rewired, pushed towards shorter attention spans and shallower forms of reading by feeds and visuals. Only by being aware of these effects, we will be able to stay in control.

Ten years after the book’s publication, Vox’s Ezra Klein sits down with Carr to discuss where we stand today. 

An interview worth checking out.

A few bumps on the road for data science

A new report by software provider Aanaconda sheds some light on the current state of data science and its role in the enterprise. Far from being a consolidated part of today’s business world, the discipline has yet to overcome a few key challenges before reaching maturity. 

Problems demonstrating ROI across the organisation. Difficulty integrating open-source tools. Attracting and retaining top talent. Tackling AI bias and ethics — quite the line-up. 

Thankfully, the report also provides specific recommendations on how to overcome these challenges. Taking a look at them won’t hurt.

New AI beats historic videogame trap

First released in 1979, Zork set a new standard for interactive, story-driven videogames. Rich in storytelling and equipped with advanced language syntax recognition, this text-based adventure prompted players to input actions at every step. 

Now, a new AI built by Georgia Tech and Microsoft Research has become the first to overcome one of the game’s most iconic bottlenecks (i.e. times where players tend to get trapped and die).

Named Q*BERT, the AI leverages NLP and reinforcement learning to avoid getting eaten by a ‘Grue’ monster whenever it moves without any lights around the game’s dungeons.

The newest new Internet

Blockchain-powered Dfinity proposes a decentralized and non-proprietary type of network that takes the power away from existing monopolies. 

It does this by allowing for apps to be built and run on the network itself, rather than exist in data centres that are increasingly controlled by large companies like Facebook and Amazon.

This so-called ‘Internet Computer’ is now open to third-party developers and entrepreneurs in a bid to spur a new era of connectivity and development. 

Dfinity launched a privacy-friendly version of TikTok named CanCan to illustrate the platform’s power. Thanks to its architecture, the app is said to do in 1,000 lines of code what Facebook does in 62 million.
