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 hardware devices. The security is one the most important features for them using system-wide security policies so apps automatically use the appropiate cryptographic package and implementing a predictive IT analytics service that identifies potencial issues before they become a problems (kind of an IPS into the lifecycle of the distribution). Even that, RHEL recognizes that even his distributions aren't safe from potencially devastating cyberattacks. 

Seems really promising these distro but we can say as a disadvantage that you have to pay for the use of it. There is a free trial of 30 days but then you can see at the Red Hat Store that the prices starts at 299$ for RHEL Workstations, following the Server Edition 349$ and more. Even though, many of today's companies choose this distro for the high-quality and support that it provides.


We can move to the second "continent" distribution of Linux, and I chose to talk about CentOS (Community Enterprise Operating System). The comparisons between these two distributions are vey much in plain sigh as the major part of the goals between these two are almost the same. 

CentOS is a free server Linux distribution which curiously his upstream source is RHEL. Is not that difficult to get it up and run, newbies can do it without struggle. The beautiful feature about is that it costs nothing to use and can be a good learning path for developers and users who want to learn to manage servers and his features. Also it has a thriving community around that has created a wealth of learning resources. The downside of CentOS is that lacks enterprise level support and in general tends to be slightly behind RHEL, also it lacks certified cryptographic protection required on government networks.


There are many other interesting Linux distros such as Ubuntu, Debian, Fedora, Gentoo and so on. I talk about these two distros to see that even though they look very similar with almost the same goals, there are different with it upsides and downsides but they con suit to any user or developer, depending on the intentions.

TWO INTERESTING REPLACED AND OBSOLETED TECHNOLOGIES

  PDA (Personal Digital Assistant) The ancestor of the modern mobile phone, a personal digital assistant that offered limited access to many modern capabilities such as Internet access, word processing, touch screen functionality and more. They were very successful in the 1980s. They were programmed using a programming language called BASIC. The suppliers of these, some of them are known today, such as Casio and Acer. In 1995 the market for these grew even more thanks to the company Palm, Inc. They even put RAM and processors in these devices years later. After the 2000s, once smartphones became popular, PDAs quickly became obsolete, but before that time they were a favourite of business people all over the world. FAX (Facsimile) Also sometimes called telefax or telecopy, the humble machine was essentially a modern version of the telegrams. For many years, it allowed individuals and companies to transmit scanned documents. There were different types of transmission: - Cable transmi...

THREE INTERESTING IT SOLUTIONS

1980s: Machine Learning Do you know that today's massive algorithms probably know you better than you know of yourself? It all started with Alan Turin saying a famous and interesting phrase in the 1950s: Can machines think? That is when they started to investigate algorithms in which machines could learn by themselves from data. Until a few years later, when an IBM researcher named Arthur Lee Samuel created the first machine learning algorithm in the game of checkers and popularised it among IT researchers. For various reasons, there were about 25 years without any optimal algorithm results and the popularity of machine learning declined considerably, until the 1980s, when the backpropagation algorithm (neural network) was developed. From then on, different algorithms were developed and improved. Until today where machine learning is one of the most used fields collecting massive amounts of data and looking for patterns among them (without privacy) to improve the experience of each...

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 ...
