Covid falls and worrying cases
18
Oct
Covid 19 already shows signs of decline worldwide, but there are still 
worrying cases such as Russia, the first country to launch a vaccine and had on Saturday (16/09) more than a thousand deaths from Covid 19, the reasons are several, the main thing is the low rate of vaccination, Russia reached 218,362 thousand deaths for a population of 145 million inhabitants.
The whole world has almost 48% at least one dose and just over 36% fully immunized, it is possible to consider that we are not out of danger, something around 60% would be desirable, at least until the end of the year for the Christmas parties , in Brazil the number of vaccinees is 73.4% at least one dose and close to 50% fully vaccinated, but the infection curve still drops very slowly.
The consequences of Variant delta are not yet known, in a balance made of the pandemic by neuroscientist Miguel Nicolelis, he stated that in Brazil we have not yet seen the face of this variant.
Winter is approaching in the Northern Hemisphere and the WHO intends to consider the possibility of a new pandemic, so that we are not surprised as this one has not ended, in November it will hold a World Health Assembly where it will study the possibility of a “treaty for pandemic”, it is necessary to consider greater solidarity and more effective combat.
The deputy director of WHO Mariângela Simão was emphatic: “there will be a next pandemic”, and added: “This is something we already know and which is inevitable, it’s a question of when it will happen” said according to the Instituto Paulista of Medicine.
Simão alerts that there is no approved vaccine yet for children, so there cannot be a national policy using vaccines that have not been approved for children under 12 years of age, and he points out that we only have one vaccine approved for use by adolescents from 12 years of age, which is the Pfizer.
He highlighted the importance of the Covax consortium that helped vaccination in poor countries, stressing the importance of donating 500 million doses from Pfizer, which will allow the entry of 200 million doses from Pfizer this year, France also made available the make donations and more countries are expected to help because, for now, it is the only vaccine for teenagers.
The danger of the delta variant and vaccination
02
Aug
Concerns are growing about the delta variant of the coranavirus, 
the indication is that some vaccines may not be fighting this variant, the growing number of infections, even in countries with advanced vaccination, is worrying.
WHO Director Tedros Ghebreyesus said two days ago to various media outlets at a press conference: “New cases of contamination and deaths continue to rise. There were 4 million new cases in one week. At this rate, we will surpass the mark of 200 million of infected in two weeks, although we know that this is an underestimated number”, he pointed out.
Since the third week of July, Europe and the United States have again registered an increase in infections due to the delta variant.
Even in China, which had controlled the pandemic, this number grew again, still small (200 cases), but it is already spread over several regions. peoples in dangerous cities will be tested.
In Brazil the moving average is below a thousand daily deaths, it slowly drops as vaccination progresses, but cases of the delta variant already appear in the country, and the real effectiveness of the vaccine in relation to this variant is concerned, there is poor monitoring in some states, testing should begin immediately and en masse, there is no evidence.
The idea of making the measures more flexible continues and will probably not go back until another outbreak, only one state (Rio de Janeiro) registers an increase, 8 states in stability and 15 in decline (São Paulo is one of these).
The WHO and the World Bank call for the urgent application of vaccines in poor countries, the average in high-income countries is the application of 98.2 doses per 100 inhabitants; while in low-income groups, the number is 1.6 doses per 100 people.
Regardless of the effectiveness of vaccines, vaccination must continue and so must restriction.
The unpredictable future of the pandemic
15
Mar
It is becoming increasingly clear that the future of the pandemic
may be far from what everyone imagines, the number of variants of the virus, scientists are beginning to identify the small variations it makes in its genetic code, and for years epidemiologists have said that we should be prepare for a next pandemic, if we haven’t done it before, now more than ever should be done.
Meanwhile, the epidemic shows no signs of cooling, despite the number dropping, in Europe for example, there was a considerable increase this week, of every 100 infections registered in the world, 41 are from Europe, the Brazilian case we have already revealed is tragic due to the records infections and deaths higher than last year’s data.
The studies on the variants also find a change in its genetic code that is frightening because with each transmission, changes in the genetic code can influence the efficiency of the vaccine (we have already explained the efficacy rates that depend on the “type” of the vaccine), that is it may happen that the next epidemic is the coronavirus itself in one of its mutations.
What to do for now, increase the vaccine and combine it with lockdown, is a cultural fact that will be difficult in Brazil and the restrictions are highly unpopular, but there is nothing else to do, and it needs to be combined with increased rates. vaccination.
Another problem is the humanitarian crisis that can occur, limiting the movement of people means limiting trade, consumption of goods, etc., which in 2020 had a positive fact, since the little circulation of vehicles and the use of non-renewable energies, it caused CO2 emissions to drop by an average of 6% across the planet, and some signs of nature rehabilitation appeared, the presence of dolphins close to the coast, which means an abundance of fish, improved levels of pollution in large cities.
However, it is important to say that the number of deaths grows that had started to decrease, returns to very worrying levels, and new bouts happen again due to the virus variants.
The economy must also be a worrying factor because there are already signs in many countries of social problems, unemployment, poverty levels and related issues: income distribution and impoverishment.
We can learn from this cruel lesson, but still most people care little about what hasn’t directly affected them yet, but it will gradually affect everyone.
Vaccination and options
07
Dec
The UK starts its mass vaccination on Tuesday, which will be 40 
million vaccines for 20 million people, due to the need for two doses of the Pfizer vaccine.
The effectiveness is around 95% and the side effects in about 2% of the volunteers are headaches and fatigue, similar to a strong hangover, however there will be other vaccine options.
Differently in Brazil, the options are small and the effectiveness of the vaccine, despite all the political propaganda surrounding the federal government’s AstraZeneca / Oxford vaccine and the São Paulo government’s Coronavac, both are much less efficient and have popular distrust.
State and municipal health secretaries published on Saturday (5/12) on the website of the Brazilian National Council of Health Secretaries (Conass) a request that the federal government acquire all vaccines against Covid-19 with proven efficacy and safety, economic interests / politicians must unfortunately prevail and we will be left with few options.
What leads us to distrust political and economic interests is the disregard for efficiency.
Two reasons are important in terms of efficiency (it is different from effectiveness), the first is that which mobilizes the natural system we have (the majority representatives are macrophages) and that develops a defense independent of the infectious agent, the second and second if the system is not enough (see su-efficient root) it mobilizes the adaptive or acquired immune system, which is more sophisticated and dependent on the type of bacteria or virus, this system must “generate” defenses (the most representative are the lymphocytes).
What proves that this is true is that all the agencies say that there is no guarantee of the end of the pandemic, and we must remain taking care of protection, time will tell and it will not cost more lives.
The pandemic plateau remains
06
Jul
The data observed in the last week of deaths by the corona virus, which are reliable
data, since the curve of infected people depends on testing, which is done by companies and is still low, indicate that the plateau remains and the pandemic is internalized in the Brazil (see graph), we have already stressed the importance of making the logarithm to better visualize the slope of the curve, which is exponential.
What the policy would be for this moment is to continue maintaining social isolation, personal hygiene, and social distancing habits, in addition to precautions in relation to municipal policies.
Any prospect of a peak, at least the data indicates, seems meaningless, the number of infections remains around a thousand daily deaths, and a #lockdown is no longer viable, as the virus has already spread and regional isolation does not mean pandemic control.
We will navigate through uncertainties, already tired of a long period of isolation and with an open and close policy that does not have much effective results, except to contain a greater contagion, without meaning any effective result of controlling the pandemic at the federation level.
The economic costs that would be great in the case of a #lockdown period, will now be higher because both the commerce and the services that effectively need face-to-face contact would not be justified to keep them disabled, and few services are non-essential.
The plan is to continue the so-called “social isolation”, whose more certain name in the Brazilian case we have already said, is “social distance” which is compatible with some open services.
The essential is therefore to maintain personal care and hope that the curve falls “naturally”.
Lockdown and frivolity
11
May
As the virus expands and begins to arrive more in the interior of Brazil and in
many places life remains “normal”, while Europe is gradually trying to return to a new normality, that is, to return to trade and consumerism and the previous hectic life , which Sloterdijk calls frivolity (see in daily El país).
There are two scenarios, the Brazilian case while some bet that the curve reached the plateau, the new data point to an even greater expansion of the virus, betting that we can contain the serious pandemic situation with little radical measures is proving inefficient.
The reason for the pressure to open trade, more than economic, it is clear that it affects the economy of the whole planet, the real reason in the minds of many people is to return to the day to day of high stress, rush and consumerism to those who have the resources for this.
In Brazil, we have reached the level of 10,000 deaths, both in personal and social life, if we reach a seriousness of a disease or take radical measures or witness the total aggravation of the disease, in the social case, the viral expansion and the worsening of the pandemic.
In the reflection of Sloterdijk, who wrote, in my view, two emblematic books Spheres and Criticism of Cynical Reason, he presents two key concepts that are co-immunity and anthropotechnics.
The first concept of co-community means that we can establish an individual commitment towards mutual protection, which would mark a new worldwide way of facing problems and the concept of anthropotechnics means understanding that the techniques, in this case and is the main concept used by Sloterdijk, the biotechnology, this is genetic manipulation.
When launched, it generated a lot of controversy in Europe, due to the manipulation of genes for example, but now that the main researches in defense of the coronavirus show the importance of the use of antibodies for the production of the vaccine, and the first thing was the genetic sequencing.
The worsening of the Brazilian crisis will require a more serious confinement, or we will see the figures extrapolate and the Health System already practically exhausted.
Confinement is necessary and the return to frivolity must be rethought as a way not only to avoid a major economic crisis, but mainly fairer.
Towards serverless computing
27
Jan
Among the trends pointed out by Nasdaq,
the electronics stock exchange, is the so-called serverless computing, with the transfer of functions to cloud storage.
Clouds start to manage the functions and storage made by servers, computing is more agile and less dependent on mobile devices, which also begin to migrate to the IoT (Internet of Things) and so the general trend may be a digital transformation, not the buzzword of fashion, but in the very structure of the digital universe.
Another consequence will be the transfer and simplification and many functions for the Web, which is confused with the Internet, but it is just a thin layer on it, written through an interpreter (a computer language with high interactivity) which is HTTP.
The creation and execution of applications is thus simpler, but this is not exactly serverless computing as indicated by a superficial literature in the area, but one of the important consequences of it.
Function as a Service (FaaS) technology is different from the application definitions in Clouds (IaaS, Infrastructure as a Service, and PaaS, Platform as a Service), where codes are written without having to know on which server that application will be executed.
Four IT buzzwords for 2020
20
Jan
Some words have already been used in an excessive 
and mistaken way, we can mention disruptive technologies seen as any that have an impact on the market, when the problem is the scale of production and consumption, the data lakes, used to store raw data that do not they mean they are or can be handled easily (there are specific environments and tools for this), and the third term that is not new is also DevOps, which is the rapid implementation of codes with facilities to remove and correct possible bugs (errors in the code ).
The four buzzwords that are expected to grow in 2020 and which represent a danger both in their use and in their implementation are BigData (yes it already existed in 2019 but its expansion is indicated as a large volume for 2020), AI ditto the previous one, Agile which means the rapid market change and corporate strategy, if misused will be a failure and ultimately and no less essential, and lastly, what has been called a “digital transformation”.
Let’s start with the last one, which includes the previous ones, including the 3 excluded from the analysis, digital transformation does not necessarily mean that “everything now changes with digital processes”, and of course it does not mean that nothing changes, depending on the area, the impact, the disruption (in the scale) it is clear that the impact can and should happen, but be careful with Agile.
Agile is the process of responding quickly to changes, but the answer does not mean being responsive in any situation, the vast majority deserve analysis such as transient market situations, seasonal processes, response to competition and in particular, changes in “fashion”.
AI can be a response to many businesses, but the term “intelligence” itself is questioned, in fact it is a bit of each previous process, including bigData, Agile and Data lakes, that is, there must be tools like Analytics and Machine Learning that assist the process.
Gartner detected an increase from 25% to 37% from 2018 to 2019 in the use of AI for business, but the effectiveness is not guaranteed, just as only the use of IT does not mean the modernization of the company.
#NoWar

Jan
General Qassem Soleimani killed in Baghdad, Iraq,
was Iran’s second most powerful person and could break the fragile balance between international forces, and the danger of a war of world proportions becomes a fearful possibility.
Iran has countries like China and Russia as allies, in addition to the Arab and Muslim world, which today is a world-class religion, and this may have a global outline of terrorism another possibility.
The security agencies set off their alarms, social media was the most talked about subject of the week, and anyone who imagines this is not serious, does not know the horrors of war: death of innocent people, food shortages, energy breaks, travels and interchance breaks and mainly increased a climate of hatred and intolerance across the plane.
Peace must be desired, and the UN, OAS and international dialogue bodies need to act.
What is diffusion of innovation
20
Nov
An innovation to reach the market, if it does not fall into disuse that is a
possibility, goes through a process called “adoption curve”.
Everett Rogers, is a recognized in this area of communication studies, professor of department and journalism of the University of New Mexico, his book Diffusion of Innovations, already 5ª. is one of the most cited books in the area, the first is from 1962, and the author died in 2004.
Their main argument is that innovation is communicated over time among participants in a social system, and the origin of their theory spans several disciplines and although it has never used the term, it can be safely stated that it is transdisciplinary.
Rogers proposes that four main elements influence the dissemination of a new idea: innovation itself, communication channels, time and a social system. This process depends heavily on human capital. Innovation must be widely adopted to sustain itself. Within the rate of adoption, there is a point at which an innovation reaches critical mass. That can also be understood as the curve of adoption
The theory characterizes 5 advantages for adopting a technology: 1) the advantage of improving an innovation over a previous generation competitor of a product, 2) from a point, a team must improve the advantage relative to its competitor in potential for there to be no return to the previous product, 3) the new product must be compatible with the previous one, not only when installing and operating, but especially with regard to the potential consumer’s lifestyle, 4) relevancy at the time of launch which means a deep understanding of the conditions that innovation finds in the moment it is launched, and 5) what is the complexity or simplicity of using innovation when it is launched, complex innovations can reach a small audience only.
An innovation to reach the market, if not fall into disuse, is a possibility, goes through a process With its successive groups of consumers adopting the new technology (shown in blue), its market share (yellow) will eventually reach saturation level.
