USABILITY, ERGONOMICS AND HCI

These three characteristics are key in the IT world. It is good to think about these aspects when developing an IT-related idea. Why? Most of the software that is popular and successful in our society like Windows, Facebook or Google, if you look at it, are developed from these features. Without these, it will be difficult to reach people, which I'm not saying it's impossible, but it's a disadvantage in your project.

Let's look at two opposite examples, one that has been successful and a parallel one that has failed, obviously based on usability, ergonomics and human computer interaction.

The example of a bad design, we would talk about Microsoft Bob.

A graphical environment running on Windows 3.1 or 95 turned the operating system into a room where each piece of furniture represented a different application. In addition, a dog named Rover acted as an assistant and gave users advice. It was a huge failure, partly due to the success of Windows 95 that same year.

As we see in this example, Microsoft wanted to squeeze the most out of the ease of use of their OS, it was a roundabout way to treat users as if they could not learn. There is very little usability, the only people who might be interested in it would be children, but it is not aimed at a wide audience.

On the contrary, as a good example and following in the branch of operating systems we can mention Windows 10 itself. Dedicated mostly to the general public, to the great part of the citizens of the world. With "extensions" for people with various problems, mostly physical problems. Easy to use and an excellent HCI. It does not leave us much freedom to modify it to your liking but if you like it from the start and knowing that almost all your relations use it, as we are sometimes weak to society, we have few options left. But in general it is an excellent OS, made for all kinds of people.

We could conclude that it is quite important to take into account these aspects in your projects or to understand why something is very successful. You always have to take them into account.

Cybersecurity in Spain

Currently, 93% of Spanish citizens use the Internet. This is why new projects are already appearing in order to increase cybersecurity as much as possible. In Spain there are two institutions created for cybersecurity under the name of INCIBE-CERT and CCN-CERT. The first one is focused on companies and citizens and the second one only for the government. I think it is worth making a separation before analysing security in Spain: before and after the appearance of COVID. Before the pandemic there was not so much concern about cybersecurity, which has affected us in the state of inferiority that we are currently in compared to the UK or Germany. There were a few projects going on but at the official conferences, most of the companies did not attend, they had their minds set on their own company's profit or other reasons. But what's the point of getting wealth when they can take it away from you in hours through malware. The key to Spain's focus on internet security was ...

RHEL vs CentOS

Nowadays the are more than 300 Linux distros. There is no one better than the other, each distro is different and one of them can be perfect for one user or unusable for another one. But, inside these 300 there are the contintents distros, that they aquired most of users and developers of the society. The other distros we can see them as small islands, not too popular but they have their specifics fans users, perfectly suited for their needs or their cusiosity. We are going to talk about two of the "continents" distros of Linux, their features, pros and conts, etc. The first distribution I want to talk about is Red Hat Enterprise Linux (RHEL), the gold stantard for the commercial Linux distributions. It is a high quality distribution created by two young american guys in 1994, available for workstations, servers, mainframes and supercomputers. It has become the most deployed coomercial Linux distribution in the public cloud thanks to the support of software applications and...

CENSORSHIP AND PRIVACY

Censorship and privacy are two very important concepts in our lives. Nowadays censorship is mostly misused. Unfortunately, it has become very much linked to the politics of each country, and this leads to unfair censorship. Privacy is a feature that in theory we care a lot about, but then in practice most of society does whatever they want and they don't even care if they use their data for anything else. But sometimes there are cases where a person loses their privacy without consent, that is the problem. Let's look at two examples, one of censorship and the other of privacy. As censorship we can use one of the most current examples and one that has affected globally. The censorship of information about COVID 19. Maybe there are people who don't agree with this but in the end it has been a case of censorship and I put it as an example. Rajat Khosla, Amnesty International's Senior Director for Research, Advocacy and Policy, said: "Throughout the pandemic, govern...
