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...
Spreadsheets as a universal programming 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.Therefore, anything that runs on mobile phones or PCs or Macs is viewed on a two-dimensional screen as a collection of rectangular cells.In conclusion, anything that runs on mobile phones or PC or Mac can be conceived as a spreadsheet both practically and theoretically.Spreads...
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...
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...

IMPORTANT Severe vulnerability CVE-2020-16898 of all Windows and its manual solution
You have to apply a security patch or do it by hand according to the news: https://news.sophos.com/en-us/2020/10/13/top-reason-to-apply-october-2020s-microsoft-patches-ping-of-death-redux/ On the Microsoft site according to: https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-16898 When you are going to download given the version of windows you have, a download of more than 1 GigaByte appears !!. Then on that same page it appears how it can be "resolved" by hand, whi...
Classic motors in Cuba 1899-2007
  Amazon puts in your hands the book: Classic motors in Cuba 1899-2007 (Spanish Edition). Launching by Hobbiesenred of the Book: "Classic Motors in Cuba".Dedicated: To the motorcyclists of Latin America, the world and especially to the Cubans.The legend of classic motors in Cuba began on September 3, 1899. Motorcycles continued to penetrate and, from that moment on, riders began to leave their footprints all over the island, thus maintaining their permanence, hegemony and development. This bo...
My fellow operators.
{loadmoduleid 135} In other articles I have commented that in the 70s our Neuroscience department had a CID-201-B minicomputer compatible with the PDP-8 of the DEC company and that the CID-201-B had only a typewriter teletype, a perforated paper tape reader, and a paper tape printer.In order to use this equipment, after developing and fine-tuning each program, it was necessary to "punch" the tapes with the data, or, for example, use the CONCATISO program (see article) to convert t...

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...
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...
Spreadsheets are limited because... and serious errors can occur.
It is known to all that the use of Spreadsheets, such as the current Excel, since the beginning when VisiCalc appeared in 1979, have allowed many users without programming knowledge to be able to develop many and varied applications.In particular, the world of economics has been empowered by Spreadsheets. An accountant can directly carry out all or almost all of his work using them, since from the beginning they were conceived with a varied communication with other data processing...

To Galita
Galita's life cycle is over, a cute little dog that my daughter Lissi picked up from the street and who gave us a lot of love and happiness.Galita was very naughty. Being at home made Dolly, another bigger dog, dump the garbage can so that she would then be the one digging for food. And that we gave her a lot of food and other things that she liked. But it seems that her nomadic life led her to try to store as much food as she could find.Galita got along with everyone. She was very sociable. I d...

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...
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...
With Variables everything, without Variables nothing.
I have said on many occasions and in various audiences that what we call variables in Programming is what frontally separates Mathematics and its language from Programming and the problems it solves.It is that it is well known that a mathematical variable is like a being without a name, which can be called X, Y, or Z interchangeably and the meaning of the mathematical formulas where it appears does not change. Also the mathematical variable is like a being without its own personali...
How I met Dr. Mitchell Valdés.
In other articles I have commented that in 1972 I was studying Pure Mathematics and I  coincide with Dr. Pedro Valdés (Peter, as everyone knows him) that he was continuing his studies in Mathematics to increase his working capacities in Neurosciences.We became good friends, we studied together in the University Park, in the Classrooms, in the Library, until one day he told me: "Tomorrow, Saturday, I'll wait for you at my house to continue."Saturday comes, I go to Peter's house, I r...
FORTRAN. The best for calculus.
It was the 70's and I continued working as a programmer for the Neuroscience Department using the laboratory computer, which in other articles I have explained that it only had 32 Kilo Words of 12 bits each, a typewriter that could punch 8-bit paper tapes. channels (bits), and an 8-channel paper tape reader.I have also commented that I programmed coding "by hand", and as soon as it was available in the machine language assembler, and also in the LEAL language, which was "postfix".T...
