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...
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...
In Honor of Roberto
It was in the early 80's of the last century when a psychologist named Roberto began to work with us, a very affable man, always with a smile, I never saw him annoying, much less bothering anyone. He was welcome in our Neurosciences collective, although he actually belonged to the psychology school of the university. He immediately became interested in using the personal computers we had to design and create applications that would have an impact on psychology. We talked a lot, he...
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...
Speaking of robots in 1977.
One afternoon of the many in which the programs we developed took hours and even days to produce results, several colleagues were meeting near our computer and the topic of robots came up.Some of us talked about the distance between the human being and the automation of processes by computers, which by the way is currently maintained, others about the development of Neuroscience itself, others the development of mathematics and computing itself, in short, almost any topic fit into...
The welcome that Dr. Thalia Harmony gave me.
Back in the year 1973-74 I have already told how Dr. Pedro Valdés took me to know the work of the Department of Neurosciences.I immediately met Dr. Thalía Harmony, one of the most intelligent and determined people I have ever met in my entire life, and knowing that I was about to finish the second year of Pure Mathematics, She knew that I had no biological training.I will never forget that he looked at me with those "inquisitive eyes" that he has and told me: "To work here you must...
To be a Programmer... without mathematics?
Programming... There are so many work and development opportunities for the Programmer and the Entrepreneur... Smart houses, the internet of things (IoT), websites as varied as the world is, mobile applications (Android, IOS), Security in communications and in business, PC applications (Windows, Mac, Chrome OS), are some examples of how varied and necessary for Programmers to do their work. Artificial intelligence? And who programs, trains, and maintains it? Programmers first. A...
My current works and ideas
My current works and ideas.Over the years I have been developing a series of works and research proposals that I would like to present to you as a whole for your consideration. For each one you will find here an introduction to the topic and also links to the complete content already more elaborated. Most of the topics are under development and from time to time I add or modify information. Keep this in mind so that from time to time you can revisit the topics that were of interest...
CONCATISO. My first Program.
CONCATISO. My first Program. Well, first I must tell you where and why the need arose for a program such as CONCATISO, my first professionally speaking program. It was the years 1972... 1973... and the Department of Neurophysiology of the Center for Scientific Research (CENIC), led by Dr. Thalía Harmony, who in passing I will say was my main mentor in my early working years, A CID-201-B digital computer was awarded, manufactured by the then Central Institute for Digital Researc...
CONCATISO. My first Program. Second part.
CONCATISO. My first Program. Second part. By reading the first part you will already have an idea of the computational equipment that the Department of Neurophysiology had back in the years 1972... 1973 Now I will tell the other part: Professor Erwin Roy John, head of the Department of Neurophysiology at New York Medical College, donated to Thalía and her Department an analog "Transient Averaging" computer called "CAT" that was capable of obtaining, from synchronized stimuli an...

Who am I and what I have programmed
Hi !. I am Octavio, and as editor of this section I offer to share your experiences in programming, from curious anecdotes to difficult moments when making large or small systems. We will also share how to solve all kinds of problems using programming as a tool, for PCs, for Mobiles, and even for the Cloud. If you are a novice, then welcome, and if you are an expert, then welcome too. All kinds of writings will be interesting to us to publish, because where else will you find tha...
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...

Basic Ideas
Basic Ideas in the History of Humanity. An idea, a conception, a way of working, of direction, and in general any human activity is considered basic when it has never been formulated by anyone before and is also so simple and powerful that multiple ideas and applications have sprung from it throughout history, but none existed or would exist without having been promoted by that basic idea that is always present in all subsequent development. Often, it's not possible to attribute this basic ide...

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...

Tapes, Punched Cards, and Machine Time.
It was the 70's and then we only had a 12-bit 32 Kilo Words computer, as I have commented, but the problems that we had to solve, especially statistical ones, needed many more resources.So I took on the task of "circumventing the bureaucracy" of the Computing Centers with their way of working: "submit the program and data on paper" and after days or weeks: "come and collect your results" or "the program did not compile" or "the program failed", which made us fix the problems on pap...
