FOCAL. Salcedo the Great.
It was the early 70s of the last century, and in our PDP-8 compatible minicomputer from Digital Equipment Corporation (DEC) there was almost no way to program except by hand-coding machine language. Later, the Central Institute for Digital Research (ICID) developed the assembler and later the LEAL language (LEnguaje ALgoritmico) that I have referred to in other articles and in which it was quite difficult and tedious to program as it was postfix notation, especially when evaluating...

Spreadsheets as a universal computing model.
Any two-dimensional screen can be viewed as a collection of rectangular cells. A point and even the entire screen can be defined as such. Almost all cell phones and computer screens are two-dimensional screens. And some may be three-dimensional. Therefore anything that runs on mobiles or PCs or MACs is seen on a two-dimensional screen as a collection of rectangular cells, or three-dimensional as rectangular cubes. In conclusion, anything that runs on mobiles or PCs or MACs can b...
How I became Section Chief of the Computing Center.
It was the early 70's and as I have commented in other articles, our Neuroscience Department had a 12-bit 32 Kilo Words computer, a punched tape reader and an extended typewriter to punch tapes.In those days, computers were scarce, very scarce, and that meant that their use as such was in the hands of large ministries or large companies, but it was very rare for a small department to have one. The self-sacrificing work of the Department staff that prior to my entry into it and usin...

Reporting 0003
First of all, let us recall the basic idea: let us spread the good news and reject the darkness of the bad... This universe is polar; there are positives and negatives. While opposite poles attract and like poles repel in the realm of electricity, in the spiritual realm, what almost always happens is that the positive attracts the positive, and the negative attracts the negative. That is why it is important to let positive news circulate —and even to support it with all our might— so that toget...
Spreadsheets. The best visual programming language.
The history of Spreadsheets is fascinating, from Richard Mattessich who in 1972 wrote the article "Budgeting Models and System Simulation" creating the concept, to Pardo and Landau, who tried to obtain a Patent.But the renowned inventor of Spreadsheets is Dan Bricklin, with his VisiCalc, which was available since 1979 and was, let's say, the first and most important computing tool in the hands of anyone when it was implemented for the first computer that we can call "personal".I kn...
The novel of Time.
I am Time. And I am more than the Time you know. I have always been and am in Everything, even before Him. I am not linear, as you think; I permeate everything from top to bottom and from front to back. I see everything to the same Me, because I am Time. I am always passing and always compacting. They measure me but they do not see me. Nor do they hear me. They cannot move me and yet I define the destiny of everything. In due time I become aware and I see. I see Everything, even Him. But I am no...

How I learned Neurosciences... with Björn Holmgren and Ruth Urbá.
Since my arrival at the Department of Neurosciences I noticed that the branch of Neuro Biochemistry was, as I say, very well represented by the brilliant Swedish researcher Björn Holmgren and his wife, the talented Chilean Ruth Urbá.In almost home-like conditions, since in fact we were working in what was known at the time as "The Laboratory House", they carried out intense research using mice as an experimental basis, and their contributions to the study of sleep and its physiolog...

I met Ileana and for a moment I was Don Quixote.
Under Rocinante's helmets I made the happiest quixot of my life.It was the 80s of the last century, and my friend Peter and I, being at a scientific event at the University, we read on a flyer that in "El Bodegón de Bartolo", a nearby coffee bar, from 10 AM it could be consumed with beer At an open bar and we couldn't hold out, we went out there with Peter's girlfriend, Yanai.When we get to the bar they inform us that no, that there is nothing at all until 5 pm, and then Yanai tell...
My current works and ideas
My current projects and ideas. Over the years, I have developed a series of projects and research proposals that I would like to present for your consideration. For each one, you will find an introduction to the topic here, as well as links to the full, more detailed content. Many of these topics are works in progress, and I update or modify the information periodically. Please keep this in mind and revisit the topics that interest you from time to time. Also, please note that some links may po...
Microsoft Access as a database is limited by design and what to do.
As the title indicates, the microsoft office database product, Microsoft Access, is limited by the company itself so that it does not compete with other products such as SQL Server and C# program development, for example.I explain:The first limitation is the commercial one. Access is not sold alone, but as part of Microsoft Office and therefore an application made in Access cannot be distributed without first verifying that the customer has a valid license of the same Office as suc...
To Manchita
I had the joy of meeting Manchita. I had never had dogs, as a child only a cat. Manchita came to us by chance. A friend of my daughter found her alone on the street, and despite the fact that for several days she made her visible in front of her house, no one claimed her. Well, my daughter stayed with her. At first I was little at home, spending time with my daughter, either in ballet classes or in her apartment. Later on, my daughter is hired abroad, and leaves us looking after...
Cats on MEDICID-1
One of the most fantastic things about having a computer in our department in the 70's is that we could do with it what we wanted, literally, without having to go through all the bureaucracy created around the so-called "Calculation Centers", where weeks and even months passed between having an idea and getting a real program to implement it. In other words, we lived through the personal computer revolution years before it even existed.In those years a young researcher, the current...
The MEDICID-1. The great little equipment.
It was 1974 and an Engineer from the Department of Neurophysiology named Alberto Caro had designed a device for the experimental work of the department that could be controlled by our CID-201-B computer, compatible with the PDP-8, which I referred to in the article "CONCATISO. My first program.".Due to production priorities, the Central Institute for Digital Research (ICID) did not give us what would later be named as MEDICID-2 and for that reason, with great inventiveness, the eng...

Vulnerabilities in Windows? They are dictated to the programmers.
Do you really think that programmers do our job "so badly" and make "so many mistakes" that we cause the thousands of vulnerabilities that the Windows operating system has had, has, and will have?As a fact, I affirm that all "legal" antiviruses ask Microsoft for various "entry and interception points" where to put their "legally added" programming to the operating system. For example, how do you think an antivirus "checks" every file before being "opened" by Windows Explorer? Becau...
