As educators, we must constantly update ourselves. In the use of new (which are no longer new) technologies, classroom management, project development, different forms of assessment, pedagogical research… And about our subject. It doesn’t matter which teaching body¹ you belong to. Internet communication has allowed different fields of study to evolve at a speed never seen at any other time in history. However, I believe that in this aspect, the field of computer science leaves all others in the dust. And if anyone doesn’t think so, well, they can come up here and prove me wrong.

Without fail.

September arrives. You’re an IT teacher. New assignment, or not. This year you’re teaching new modules. You review contents, objectives, learning outcomes, and evaluation criteria. With the Law and curriculum¹ digested, the question arises: What technologies should I select to teach what I need to teach?

You search for teaching materials to shed some light. This is a bit outdated, this is hardly used, this has potential but isn’t stable or complete enough…

Most people use the last days of the year as a point of reflection about the events of the past few months and the objectives they want to set for themselves, taking advantage of the beginning of a new year, as if the night of December 31st to January 1st were somehow different from all others, somehow allowing a fresh start. However, for teachers, the magical night is the one that occurs from August 31st to September 1st. Because we don’t measure the passage of time in years, but in school years. During the break at the end of December, we are too busy planning the second trimester to also contemplate our lives at that moment.

It always happens the same way.

When I set out to create some kind of educational material, like a practical guide, I can’t shake this question from my mind: In what format should I create it?

It might seem like a trivial question, perhaps I should focus solely on the content, but the reality is that it’s not.

On one hand, I’m interested in the format remaining relevant and usable for as long as possible. Creating the material takes time and effort that you won’t get back, so it would be a shame to do it with a proprietary tool that depends on a cloud service and over which you have no control. Even if they’re tools that are promoted everywhere and are trendy in the educational field. Maybe the result is very attractive but… Depending on a company’s interests to keep accessing my material? No, thanks. By the way, this argument also includes making it easy to change and maintain in the future… Practical guides in the field of IT become obsolete very quickly.

On June 7th, at the annual WWDC¹, Apple presented the new features in their operating systems. One of them was Private Relay.

But first, let’s add some context (you can skip this if you have basic knowledge of networks). When we browse the internet, we do so identified by an address called IP. This IP is necessary so that when we make a request to a website, the response can return to our device. Additionally, to know the IP of the website we want to visit, we have to ask another server (this is a DNS request). At the end of the process, both our IP and the website we’re going to visit are known by:

A few days ago, a draft Royal Decree¹ was published updating certain Vocational Training qualifications². Among them, modifications are proposed to the qualifications of Higher Technician³ in Web Application Development (DAW)⁴ and Higher Technician in Cross-platform Application Development (DAM)⁵, two of the three higher degrees in the Computer Science and Communications family. Proposals for changes to these modifications can be submitted until March 30. Up to this point, the process seems appropriate.
