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...
Pedro Valdés from Neuro found me... and I was looking for the same thing!
I will tell how I started working in the Department of Neurophysiology of the National Center for Scientific Research. It was the year 1971 and I was studying Pure Mathematics at the University and it turns out that a doctor, Dr. Pedro Valdés Sosa, better known as "Peter", also began to study Mathematics as a second career. Peter and I were together for almost two years, we became good friends, we even studied together. Peter was already a worker with many obligations, he skippe...

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...
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...
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...
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...
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...
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...
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...
The Goto. The great forgotten. Not to think structured.
I still remember when I was programming with GoTo. Programming without using it was not conceivable. Until the revolution started by Dijkstra with his note "Goto considered harmful" came to "structure" our minds for program development.The progress made with "Structured Programming" is incalculable, which allowed not only to increase the speed of having correct programs, but also to increase the number of people capable of programming.At that time, "Top to Bottom Programming" and "...
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...
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...
Antiviral treatment for dengue AIDS and others via genome sonification, applied by bone conduction.
https://sonictreatment.havanatrends.com/  It is important not to listen to the audios but to put large headphones behind your ears in order to apply this antiviral treatment via bone conduction. Summary: Antiviral treatments can be made using the audio generated from an encoding of the entire genome of various viruses, an encoding that creates a numerical series that can be sonified . The generated audio files are attached or you can download them using the listed links. It is very important t...
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...
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...
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...
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...
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...
