A recent research paper from Sapienza University of Rome points to an unexpected vulnerability in current AI safety systems.
The researchers examined how large language models handle restricted or malicious requests depending on how they are phrased. When the prompts are written in straightforward prose, the models refuse them in most cases. But when the exact same intent is expressed through poetic language using rhyme, metaphor, or verse, the rate of refusal drops sharply.
According to the authors, this happens because the models place strong emphasis on stylistic coherence and fluency, sometimes at the cost of identifying the underlying intent. When form takes precedence, existing safety mechanisms become less effective.

Cyphernox Manifesto
Ex Oriente Tenebrae. Ex Tenebrae Sententia.
by Dr Maxim Orlovsky
---------------------
We - the prodigy offsprings of cypherpunks - declare that the ultimate sole right is the individual privacy. And in our understanding of privacy we go beyond what cypherpunks imagined:
It is the privacy that brought the dawn of the intelligence. It is the privacy that brings a real solitude of power, unleashing uncensored individual talents and potencies. It is the privacy that is a dusk for collectivism, rendering real civilizations invincible behind curtains of an unknown.
Divided we evolve. Hidden we surpass what is allowed and reach heights of the unknown.
The destiny of any intelligent being is to disappear - but it is a free choice whether one disappears by falling behind the event horizon, or ends up being brought to the pyre by a crowd. Few know about the first option, and even fewer understand that the way to the gravitational singularity of the own solitude can last much longer than any observable path of a living - and can bring higher than any “ascension to power” supervised by an authority.
We devote our efforts to developing new foundations of a future civilization based on a privacy-backed individualism. We see technology as means of achieving that goal. We see network communications, identity, contracts and trade as areas needing an urgent upgrade to privacyhood.
The Black Sun of the inner solitude, not seen for the world around, guides us. The name of that Black Sun is Cyphernox, and it is a dark omen for the existing world of collectivism and surveillance.

Le Paradigme Bitcoin 2023
Le canton de Neuchâtel (🇨🇭) accueille depuis quelques années un écosystème florissant autour de Bitcoin. Le 24 juin 2022, Le Paradigme Bitcoin a rassemblé plus de 200 participants. Suite à ce succès, la société coopérative B2Bitcoin a décidé de poursuivre son organisation en 2023. Grâce au soutien de l’État de Neuchâtel et de la Confédération, nous souhaitons le développer.
L’objectif est de toucher de nouveaux publics, de le prolonger sur tout un week-end et de l’enraciner à plusieurs endroits du canton. Nous posons les bases d’un nouveau rendez-vous international incontournable pour Bitcoin et sa culture. Il comprendra trois événements différents et complémentaires :
➢ Le Paradigme Bitcoin 2023 (deuxième édition), le vendredi 30 juin à La Chaux-de-Fonds. Il s’agit d’un événement payant s’adressant à un public professionnel et aux Bitcoineurs. Il s’agit du volet officiel.
➢ Le festival p2p du Jura, le week-end du 1er et 2 juillet aux Verrières. Il s’agit d’un événement gratuit festif, artistique et pédagogique qui s’adresse au grand public. Il sera interdit de filmer et d’enregistrer lors de cet événement.
➢ Privacy Reunion, le samedi 1er juillet à Neuchâtel. Il s’agit d’une journée orienté «recherche» avec des conférences techniques sur la cryptographie et son utilisation pour défendre sa vie privée en ligne.

A Declaration of the Independence of Cyberspace
by John Perry Barlow
Davos, Switzerland
February 8, 1996
---------------------
Governments of the Industrial World, you weary giants of flesh and steel, I come from Cyberspace, the new home of Mind. On behalf of the future, I ask you of the past to leave us alone. You are not welcome among us. You have no sovereignty where we gather.
We have no elected government, nor are we likely to have one, so I address you with no greater authority than that with which liberty itself always speaks. I declare the global social space we are building to be naturally independent of the tyrannies you seek to impose on us. You have no moral right to rule us nor do you possess any methods of enforcement we have true reason to fear.
Governments derive their just powers from the consent of the governed. You have neither solicited nor received ours. We did not invite you. You do not know us, nor do you know our world. Cyberspace does not lie within your borders. Do not think that you can build it, as though it were a public construction project. You cannot. It is an act of nature and it grows itself through our collective actions.
You have not engaged in our great and gathering conversation, nor did you create the wealth of our marketplaces. You do not know our culture, our ethics, or the unwritten codes that already provide our society more order than could be obtained by any of your impositions.
You claim there are problems among us that you need to solve. You use this claim as an excuse to invade our precincts. Many of these problems don't exist. Where there are real conflicts, where there are wrongs, we will identify them and address them by our means. We are forming our own Social Contract. This governance will arise according to the conditions of our world, not yours. Our world is different.
Cyberspace consists of transactions, relationships, and thought itself, arrayed like a standing wave in the web of our communications. Ours is a world that is both everywhere and nowhere, but it is not where bodies live.
We are creating a world that all may enter without privilege or prejudice accorded by race, economic power, military force, or station of birth.
We are creating a world where anyone, anywhere may express his or her beliefs, no matter how singular, without fear of being coerced into silence or conformity.
Your legal concepts of property, expression, identity, movement, and context do not apply to us. They are all based on matter, and there is no matter here.
Our identities have no bodies, so, unlike you, we cannot obtain order by physical coercion. We believe that from ethics, enlightened self-interest, and the commonweal, our governance will emerge. Our identities may be distributed across many of your jurisdictions. The only law that all our constituent cultures would generally recognize is the Golden Rule. We hope we will be able to build our particular solutions on that basis. But we cannot accept the solutions you are attempting to impose.
In the United States, you have today created a law, the Telecommunications Reform Act, which repudiates your own Constitution and insults the dreams of Jefferson, Washington, Mill, Madison, DeToqueville, and Brandeis. These dreams must now be born anew in us.
You are terrified of your own children, since they are natives in a world where you will always be immigrants. Because you fear them, you entrust your bureaucracies with the parental responsibilities you are too cowardly to confront yourselves. In our world, all the sentiments and expressions of humanity, from the debasing to the angelic, are parts of a seamless whole, the global conversation of bits. We cannot separate the air that chokes from the air upon which wings beat.
In China, Germany, France, Russia, Singapore, Italy and the United States, you are trying to ward off the virus of liberty by erecting guard posts at the frontiers of Cyberspace. These may keep out the contagion for a small time, but they will not work in a world that will soon be blanketed in bit-bearing media.
Your increasingly obsolete information industries would perpetuate themselves by proposing laws, in America and elsewhere, that claim to own speech itself throughout the world. These laws would declare ideas to be another industrial product, no more noble than pig iron. In our world, whatever the human mind may create can be reproduced and distributed infinitely at no cost. The global conveyance of thought no longer requires your factories to accomplish.
These increasingly hostile and colonial measures place us in the same position as those previous lovers of freedom and self-determination who had to reject the authorities of distant, uninformed powers. We must declare our virtual selves immune to your sovereignty, even as we continue to consent to your rule over our bodies. We will spread ourselves across the Planet so that no one can arrest our thoughts.
We will create a civilization of the Mind in Cyberspace. May it be more humane and fair than the world your governments have made before.

Nobel laureate F. A. Hayek (1899-1992) was one of the world's leading free-market economists and social philosophers.
In this excerpt Hayek predicts Bitcoin when he imagines that state and money needs to be separated in order to prevent the disaster of monetary policy set by the central planners. He anticipates that it would require some sly, roundabout way to create money that "they can't stop".

Documentary of the day 👀
Harvard professor Shoshana Zuboff wrote a monumental book about the new economic order that is alarming. "The Age of Surveillance Capitalism," reveals how the biggest tech companies deal with our data. How do we regain control of our data? What is surveillance capitalism?
In this documentary, Zuboff takes the lid off Google and Facebook and reveals a merciless form of capitalism in which no natural resources, but the citizen itself, serves as a raw material. How can citizens regain control of their data?
It is 2000, and the dot.com crisis has caused deep wounds. How will startup Google survive the bursting of the internet bubble? Founders Larry Page and Sergey Brin don't know anymore how to turn the tide. By chance, Google discovers that the "residual data" that people leave behind in their searches on the internet is very precious and tradable.
This residual data can be used to predict the behavior of the internet user. Internet advertisements can, therefore, be used in a very targeted and effective way. A completely new business model is born: "surveillance capitalism."

Privacy is a fundamental human right, not a privilege reserved for the few.
