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...

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...

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 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...

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...

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...

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...

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...

Real and Fiction Story Telling

You can write, we know. And so do we... You can write, we know. Do you think the influencers knew that by recording videos they were going to have millions of followers? Well, no, they did not know, but each and every one of the audiovisual influencers have been and are sincere in doing what they do, for different variants that exist. Well, writing is easier than making videos, even if it doesn't seem like it, just because it's visually anonymous, which I believe is very importa...

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...

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...

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...

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 "...

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...

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...

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...
