Cyber blackout and wars
22
Jul
The blackout that happened last week is one of
the biggest in history, it caused confusion in many airports (see the US Flights chart bisede), TVs, banks, hospitals and services that depend on digital communication, but it was not with military motivation, the The company CrowStrike, behind the blackout, declared Friday (19) that “this was not a cyber attack” and that the company’s team “is fully mobilized to guarantee the security and stability of the company’s customers”.
According to an interview with Rob D’Amico, a former FBI agent, despite there being no military motivation: “They may not be involved in what happened, but they are observing what happened, what the reactions were, the response times, how this has been corrected, so that if they consider an offensive cyber operation against the United States, they can map what was done”, he said in a statement to CNN.
It is worth remembering that the historic beginning of the Internet was a project with DARPA, an American department for strategic projects that envisaged network operation that did not harm communication, so the first electronic network was called Arpanet.
This is extremely strategic because a cyber failure can leave both the communication system and the defense itself defenseless, which depends on communications to be activated, extremely weakening the system that is under attack.
Ukraine has announced that it has managed to directly affect Russia’s command and defense systems, while Russia seeks to weaken Ukraine’s energy supply system and land communication channels, it also plans a railway in its domains on Ukrainian soil, revealing tactics differentiated defense and attack.
As war rhetoric and everyday political and ideological wars advance, a greater than cybernetic blackout is announced, minds and souls become increasingly cloudy and the dark horizon hides hopes, refuges and clearings.
Those who fight and desire peace lack nothing, not even what war and hatred try to take away from everyday peace, the moment of rest and leisure, not that fantasy of orgy and false freedoms that destroy a fruitful and happy life, there is always a shadow, a clearing and a pause for breath in the midst of modern acceleration.
“Even if I pass through the valley of the shadow of death, I will fear no evil” (Psalm 23:4) says the psalmist of the dark period of the Hebrew people, and thus those who desire and fight for peace sing joyfully.
The path and the narrow gate
07
Dec
It is common sense culture that we should
seek a region of comfort or security, but it is neither in the great paths developed by current ideologies nor by the wide door of facilities, in fact the great populists of today are sellers of facilities that are expensive security and the popular economy.
[It is always easier and more popular to propose what seems obvious, to distribute benefits or to favor big companies and big banks to make the economy grow, but they are the greatest causers of havoc in the popular economy, as we developed in the last post to idea of tolerating crimes as a way of destroying culture and favoring marginality, what is called impunity is actually the wide door path to social cultural re-education.
People who grow up and develop a safe and secure life, if they are not thieves and sellers of facilities, are those who have gone through deprivation and difficulties to build a stable and sustainable life, even in the midst of crises and periods of difficulties such as the pandemic is being. which is hard to complete, social health agencies are important, but without personal care what they do is palliative.
For Christians, the biblical passage that says (Mt 11k28): “Come to me, all you who are weary and burdened, and I will give you rest” is complemented in the following verse Mt 11,29: “ Take my yoke under you and learn from me, for I am meek and humble of heart and you will find rest”, which is omitted by religious people who proclaim the wide door of miracles and favours.
In the numerous correspondences that the famous physicist Niels Bohr exchanged with Albert Einstein, one of them is quite revealing, in which Bohr writes to Einstein that the root of all evil lies in the idea of men that someone can possess all the truth, she who was not a believer writing to Einstein that he was, brings a fundamental idea to know that all wisdom is not present in human consciousness.
Likewise, those who proclaim the pride of possessing all the truth or all the answers to human designs, even if they proclaim divine ideas, do not hold the whole truth, which is why the importance of the verse we pointed out: “learn from me that I am meek and humble in heart,” there is no haughtiness in godly wisdom and no desire for war or strife.
Where is the divine locus
10
Nov
Of course the divine locus is anti-spatial and temporal, even modern
quantum physics developed the theory of the space-time dimension as the only dimension and where there are folds in time, but it is likely that physics will still make discoveries greater than wormholes. , accelerated space travel dimensions and will change our cosmic view of space.
The latest discoveries by James Webb, the telescope that looks at the origin of creation, already sees in what astronomers call the pillars of creation, the new images (10/19) show formations that look like rocks, but which are clouds of gas and dust of astronomical dimensions, where stars and celestial bodies are formed, in a kind of nursery.
The new image, using James Webb’s infrared resource [and it is possible to better observe the dust in this region of star formation (Image from NASA above), improving the image on the left of 2014 from the Hubble telescope, the image on the right being the image by James Webb.
In terms of the eschatological cosmovision, the one that studies the beginning and end of humanity, it is possible to imagine that through a “time warp”, we are still stuck in Einstein’s physics, this cloud forms and starts a development of stars, supernovae and galaxies in the universe.
The divine plan is even broader, since the time of Jesus, men wanted to know when the “kingdom of God” would be formed, an earthly dimension in which our human condition would be elevated to a level of happiness and prosperity that would reach everyone. , “where milk and honey flow”, but the master’s answer was not very pleasing to those who wanted something more tangible.
The reading in John 1:20-21 says they wanted to know the moment of this “kingdom” and Jesus replied: “the kingdom of God does not come ostensibly, nor can it be said ‘is here or ‘is there, because the kingdom of God is among you”, that is, it must take place among men, so there will still be many changes in the human and earthly dimension until this stage.
And the passage clearly says that before this the son of man (Jesus who is a presence of God among us said above), will have to be rejected and will suffer much.
Thus, it is necessary to find spaces of solidarity and fraternity among men where these seeds of full life are developed, men understand each other and look with love for their fellow man, without contempt or exclusion.
So this kingdom is near where there is love and brotherhood and far away where there is greed and exclusion.
Different reactions to dominant thinking
03
Feb
In countries that were colonies of Europe, the term decolonization
emerged, which differs from decolonization because it penetrates precisely into the dominant thought and epistemology (some authors will call it epistemicide), which is not the simple liberation of domination, but also the resurgence of cultures. subalterns.
Thus, authors appeared in Africa (such as Achiles Mbembe), in Latin America (Aníbal Quijano and Rendón Rojas y Morán Reyes), as well as authors of original culture such as indigenous peoples (Davi Kopenawa and Airton Krenak), but a dialogue with European authors is possible. open to this perspective like Peter Sloterdijk (speaks of Europe as the Empire of the Center) and Boaventura Santos (speaks of epistemicide and also some concepts of decolonization), there are many others of course.
Christian culture must also be highlighted in these cultures, seen by many authors as a collaborator of colonialism, one cannot deny the historical perspective and also the doctrine that is the liberation of peoples and a culture of fraternity and solidarity, it is also a minority today in Europe and persecuted in many cases.
Among the Europeans who defend a new humanism, or a humanism in fact, since the Enlightenment and materialist theories failed to contemplate the human soul as a whole, and are therefore a one-legged humanism, among the Europeans I highlight Peter Sloterdijk and Edgar Morin, the first who defends the concept of community as a “protective shield” capable of saving our species, and the second, a planetary humanism, where man is a citizen of the world and diversities are respected.
Both consider the proposals populist, it is good to know that there are left and right, they must lose with the current crisis and global consumerism depends on an atmosphere of “frivolity” or superficiality that humanity will be forced to rethink, we will not go back to that what we consider stable, the original writers themselves, as Davi Krenak highlights in several interviews, what we want to return to was not good, there was no real happiness and well-being in what was considered normal.
As an aspect of the construction of thought, in Sloterdijk I highlight anthropotechnics, for him modernity was a de-verticalization of existence and a de-spiritualization of asceticism, while the knowledge and wisdom proposed in antiquity leave the empirical and the deceptive to go towards the eternal and of the true, as religion does not exist for him, it would be a movement of wisdom and knowledge, and not just an asceticism of exercises, where the immortal soul was exchanged for the body.
In Edgar Morin’s perspective, it is the hologrammatic perspective that can give man a vision of the whole, now fragmented by the specialization and particularity of each branch of science, a paradox of the complex system in which man is a part that must be integrated into the whole, where “not only the part is in the whole, but in which the whole is inscribed in the part”, the pandemic taught us this, but the lesson was still poorly learned, in the middle of the pandemic crisis it was decided that everything is released and there is no protocol for protection of all in each (each part), and there is no co-immunity.
Christmas gift
24
Dec
In December 1947, right around Christmas, three Bell Telephone
engineers (William Shockley, John Bardeen and Walter Brattain) invented the transistor (TRANsfer reSISTOR) that revolutionary communication and later computing, also ICs (Integrated Circuits) have as a base the transitor.
The big event this Christmas will be the launch of the James Webb Space Observatory (jwst, James Webb Space Telescope) from the Kourou space base, in French Guiana, at 9:20 am EDT, which will be taken to the Ariane 5 spacecraft. made at the cost of $10 billion, the most expensive space project in history.
What are we going to look for in space, in addition to other puzzles, the origin of the universe in its early stage, and it’s curious why this happens this Christmas, and why it is so special.
Lights decorate cities even in attention with a possible new wave of the pandemic and also a new flu, they light up hope and make us look to the future and to the beginning of our lives, our planet and humanity.
There is no way to escape from utopians, cosmogonies and religious eschatologies, even if we can solve many enigmas, the philosophical question remains: why there is everything and not nothing.
The answer can only be ontological, there is a reason for being and there is a promising future, where there is hope if we return to the logic of Being, of dialogue and of the encounter with the Other.
The message cannot be any other than that which speaks of brotherhood and peace, both not yet fully achieved by humanity, Christmas reopens this hope.
This is the prophecy that Isaiah announces (Is 52,7 when there will be true peace: “how beautiful they are, walking on the mountains, the feet of him who proclaim and preach peace, of him who proclaims good and preaches salvation, and says to Zion, ‘Reign thy God,’” the message that believed in the coming of the Savior, the birth among men of the Messiah.
The lights in the city not only announce this light visible to the eyes, but those that open the heart to friendship and peace (Jn 1:4-5): “in her was life, and life was the light of men. And the light shines in the darkness, and the darkness could not overcome it”, because a tiny point of light already dissipates the darkness, and this is our hope.
May Christmas renew hopes for a possible and sustainable future for humanity, and may justice and peace reign in a new world.
An oriental philosopher reads the “clearing”
19
May
Byung Chul-Han is a Korean-German philosopher who migrated
to the West and does an odd reading of Western literature, in particular the context of networks and new media, studied in his doctorate Heidegger and with this his “clearing”.
He explains what the clearing is in a simple way: “Heidegger’s ‘truth’ loves to hide. It is not simply available. It must first be ‘taken off’ from its ‘veiling’. The negativity of ´veiling´ actually inhabits as its ´heart´ ”(Han, 2018, p. 74) and in this excerpt he quotes Heidegger´s work:“ On the question of thinking ”.
It penetrates what information means, the great input of the current veiled Being, “the information is lacking, on the other hand, the interior space, the interiority that would allow to withdraw or to be veiled. It doesn’t beat, Heidegger would say, no heart ”(Han, 2018, p. 74).
This absence of counterpart, is what Chul Han calls negativity, it is good to explain it well, “a pure positivity, a pure exteriority characterizes the information”, so is the reflection.
As the information of negativity would then be, in the sense of reflection, it is the “selective and additive information, while the truth is exclusive and selective. Unlike information, it does not produce any pile [Haufen] ”(Han, 2018, p. 74).
Thus, there are no “masses of truth” but “masses of information”, it is the “massification of the positive” (Han, 2018, p. 75), so information is distinguished from knowledge, and this is not “simply available”, I would say neither simply because it is complex nor available because it is hidden.
However, the philosopher confuses it with life experience, when he affirms: “not infrequently, a long experience precedes it” (page 75), and affirms only one side of the information: “the information is explicit, while knowledge often takes a implicitly.”.
Clarifying these two confused points, first the question of experience, the philosopher Plato was the first to announce that wisdom, as knowledge of the truth is not the result of age, if it were only in old age people would deserve to be heard, the other question is about tacit information, it exists as tacit knowledge, Michael Polanyi (1958), was one of the first theory, and Collins in the seventies returned to the concept in the scope of scientific communication. For this tacit information, Chul Han also points this out, “silence” is needed.
The deepest clearing the philosopher describes quoting Michel Butor, who gave an interview to Die Ziet on 07/12/2012, which points to the real cause: “The cause [of this] is a communication crisis. The new means of communication are worthy of admiration, but they cause a hellish noise ”(Butor apud Han, 2018, p. 42).

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.
Totality and infinit
16
Jan
The complex is fundamental for understanding
wholeness, Edgard Morin wrote: “Only complex thinking can civilize our thinking” (Morin, 2008, p. 23), in the absence of a totalizing and comprehensive discourse, complex thinking itself is.
Giordano Bruno was the first to intuit that the infinite was fundamental to the nascent modern thought, but this one took refuge in the rational dualism (objectivism x subjectivism) and in the human finite that does not admit the mystery and the infinite present in the cosmic totality.
Current thinking, thanks to the physical complexity that came from quanta and relativity theory, is launched into the depths of the universe to think about matter and dark energy and their new and eccentric phenomena that challenge current models of physics, science, and maybe religion.
Edgar Morin, before reflecting on the paradigmatic turn, says that the West “the fruitful child of the schizophrenic Cartesian dichotomy and clerical puritanism, also commands the double aspect of Western praxis, on the one hand anthropocentric, ethnocentric, egocentric since it is the subject ( because based on the self-worship of the subject: man, nation or ethnicity, individual) by another and correlatively manipulative, icy “objective” since it is the object ”(Morin, 2008, p. 81).
Without considering themselves dogmatic, arrogant, and self-referential, this thought, even when projecting to the Infinite, even appealing to God and even invoking dialogue, is itself arrogant, the slightest amount of questioning enough to note arrogance.
Now, even for the religious to admit the mystery, it is indispensable to admit the idea of God and the infinite, while for the “rational” thought (not the dogmatic rationalism) to admit the complexity of the phenomena is only to make serious science and to investigate the reality, nature on the one hand, and to admit man’s place within it is the only possibility of overcoming the objectivist and egocentric arrogance of modern thinking.
The infinite that is also claimed by current thinkers such as Ricoeur, Lévinas who explained the sense of alterity before the Infinite: “The idea of infinity does not start from Me, nor from a need for the Self that accurately assesses its emptiness. In it the movement starts from the thought, not from the thinker. ”(Levinas, 1988, p. 49).

Quantum teleportation chip
30
Dec
The phenomenon is called quantum entanglement,
or teleportation, once made with particles, now with signals was made between chips.
The feat was done by researchers from the University of Bristol and the Technical University of Denmark, where the team was able to send data without the chips being close.
The achievement means a jump in teleportation because it is now coded signals, which makes communication via teleportation possible.
The research paper has already accept to been published for publication in Physical Review Letters and is available on the open prepress access server arXiv.org.
The following video explains quantum entanglement:
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.
