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...

THE MOTORCYCLES OF INDEPENDENCE (1885-1940)
Loading...
The articles presented in this space are the authorship of Onelio García Pérez and his friends, © www.HobbiesEnRed.com, based on empirical research, there have been few investigated periods as a result of addressing issues that go beyond the particular objectives of the Author. The historical approach present in the fascicles is the product of the limited bibliography available...
Program and fine-tune in assembler binary
It was the years 1973, 1974,...In the article on "CONCATISO my first program" I described in broad strokes the characteristics of the computer CID-201-B compatible with the PDP-8 of the DEC company.Recall that it was 12 bits long, but also only had a 12-bit accumulator register and 1 carry bit.Machine language instructions were encoded in those 12 bits where sometimes another word was used to access groups of 4096 (12 bits) memory words, and thus be able to access all 32 Kilowords...
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...
A doctor and a monkey overboard!
It was the year 1977-78 and by then Dr. Mitchell Valdés had already made much progress in psychophysiological experimentation using MEDICID-1 and MEDICID-2 as reported in other articles, even using cats as experimental subjects.Then he is visited by Dr. Erwin, who had managed to create a vervet monkey business on the island of Saint Kitts. It is important to clarify that the vervet monkeys, brought to Saint Kitts by the conquerors from Africa, are compatible with man in many respec...
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...

Do you want to stop Windows 10 updates?
As it will have happened to all of you that for years Microsoft has imposed its Windows 10 updates above any personal or business consideration of those who have bought its product.And let's not say that they are only critical and security updates, along the way it has already imposed more than five versions of Windows 10 associated with the "continuous update" system that they implemented as a universal solution to the problems of Windows 10 itself.Well, along the way there have b...
What Homer Didn't Tell Us...
Troy, a great epic of ancient times. Do you remember? Paris, the Trojan prince, abducted Helen, wife of Menelaus, the Greek king. Menelaus, his pride wounded, but with the true intention of seizing Troy and thus controlling its trade and strategic location, launched a great invasion that resulted in a total siege of Troy for ten years. So, to put it in modern terms, which are also favored by high-ranking officials of the most powerful country on Earth, what do you think was happening in the "re...
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...
Reporting 0001
We are diverse; we have our strengths and our weaknesses. Yet, as human beings, we have become accustomed to reading and sharing bad news —the world's problems, accidents, wars, and the consequences of government actions that, even when intended to benefit the population, sometimes bring about greater harm. Let us, then, make a habit of neither reading nor following such news —even when it affects us directly— for all gain is essentially spiritual, and all loss is spiritual as well. Consider th...
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...

Human Facebook.
Yesterday walking and walking I went to repair a fan where a technician who has been repairing electrical appliances for more than 20 years, has a lot of experience, is fast and accurate.Upon arrival there was a "return at 2:30" sign and waiting for it a Mrs. arrived with a rice cooker. Well, we started talking and talking, and I said to myself, why wait until everyone has internet to use Facebook? Facebook we have it within reach...Well, without meeting each other, exchanging pho...
How we finish the ANFACT.
Well, I didn't know whether to put this article in "Stories" or if here, in "ProgramSolving", but in the end, due to the randomness of the Programming, I decided to put it here.It was between 1973-1974 and a Programmer from the Center's Department of Mathematics, Raisa Cepero Bonilla, was in charge of carrying out a project to carry out a "Factorial Analysis by Correspondence", which is a fairly sophisticated statistical analysis and not very broad utilization even today.It was pro...

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...
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.
