I'm not usually a fan of petitions, but it blows my mind that over 7900 Paraguayan tax residents (citizens and expats) have signed petition against dangerous reporting that puts people at risk. People actually care. And these are not random people from internet, but tax residents. You have to sign with your tax id. All is not lost. And by all I mean my faith in human brain. queremosquedarnos.org

@stalliondelsur @wilderko I don't think it's for DNIT. It's for media pressure.

Great effort, however, this makes zero impact in PY, unfortunately. 1. Petitions are not popular. Many locals will never sign them. 2. RUC numbers are publicly known → it makes no sense to use them. DNIT will either tell you that you have too few signatures (irrelevant) or claim you faked them due to the public availability of RUCs and "signing" on behalf of others. There are approx. 1 million active RUCs. Just to put it into perspective. 3. We are executing some steps locally to have a shot, it needs to be fought.

Sign and share a petition against the new crypto regulations! queremosquedarnos.org

@jpthor It should have deleted Telegram, it's a spyware

Whoops. Woke up to everyone asking me why i was quitting telegram groups. One of my agents went a bit rogue and nuked my entire telegram, Gmail and iCloud mail 😅 I had asked it to go thru, learn me, save important data, delete old irrelevant emails/messages. It optimised too effectively 💀 Brave new world. The only memory of those messages are now saved in it is memory files - guess I’m stuck with my agent now 🤣

@wilderko @TheJerzWay @kotasjn Make Paraguay safe again :)

Truly wild story 🤯. A new era of "citizen science" is beginning. An engineer with no medical training used ChatGPT and Google’s Alphafold (AI protein sequencer) to build a working cancer vaccine from scratch. He turned raw genetic data into a custom mRNA vaccine that shrank his dying dog's tumor by 50%. Paul Conyngham spent $3000 to get the DNA sequences of his dog's healthy blood and the cancerous tumor. He was staring at gigabytes of raw genetic code without having any clue how to read biological data. This is exactly where ChatGPT became the crucial missing link in his process. He used ChatGPT as a high-level biological consultant to figure out how to compare the two DNA samples and spot the exact mutations causing the cancer. ChatGPT gave him the step-by-step instructions to run the data pipelines and pointed him toward an AI tool called AlphaFold to map the physical shape of the damaged proteins. The chatbot basically translated complex oncology concepts so he could write a half-page chemical recipe for an mRNA vaccine. This mRNA is just a genetic instruction manual that tells the immune system how to recognize and attack those specific mutated cancer cells. University researchers were blown away by his formula and manufactured the physical vaccine for him. A veterinary expert then injected the dog, and within weeks the massive tumor had halved in size.

Priatelia, @SadeckaMarianna sa rozhodla po cca dekáde zorganizovať pokračovanie konferencie Bitcoin je retro. Kým nie je von program, sú k dispozícii lacnejšie lístky pre ranné vtáčatá. Akcia bude 25. apríla 2026 (sobota) v A4 12:00-23:00. Čakajú vás OG cypherpunks a zamyslenie sa nad tým, či je Bitcoin retro (podľa mňa nie, ale neviem, či vás presvedčím!:). bitcoinjeretro.cypherpunk.today

@gerti_t @levelsio Yes, because of socialism. But blood tests are actually capitalism and they work pretty well. You just need to skip both the doctor and the socialist insurance company. x.com/jurbed/status/…

@levelsio @jurbed I’m learning the hard way that Western European medical system is actually 2nd world

I was never able to do blood tests when I asked for it in Netherlands Doctor asked "why? you're not sick?" Then I tried in Portugal (at Germano de Sousa) but they never picked up the phone or when they did were so slow and unhelpful I gave up, they also require a doctor prescription btw The first place I could get my blood tested was Thailand in 2018, I just walked into Bumrungrad and asked for it, amazing experience Last few years we just fly to Brazil and do it here, the nurse comes to your home/hotel at 8am and takes your blood, same or next day results online I find it funny I keep having to fly out of Western Europe to do blood tests, they make it impossibly hard to do them Which is retarded

Richard Feynman’s savage takedown of pseudo-science still burns in 2026: “Social science is an example of a science which is not a science. They follow the forms… but they don’t get any laws. They haven’t found out anything.” He goes harder: Experts who “sit at a typewriter and make up” claims — “organic food is better,” “this diet cures everything” — as if it’s settled science, when no rigorous experiments or checks have been done. Feynman: “I know what it means to really know something. How careful you have to be. How easy it is to fool yourself. I see how they get their information… and I can’t believe that they know.” The Nobel physicist calls it straight: most of what passes for “expert” opinion is noise dressed up as knowledge. In an age drowning in TikTok “science,” influencers, and clickbait studies — Feynman’s 1:52 rant feels more relevant than ever. Who’s the biggest pseudo-expert that grinds your gears right now? Clip is timeless fire — watch it and feel the clarity.

@levelsio Slovakia - you order them online and just go to have your blood drawn. Results same day. I went to look and they do it now in Netherlands as well. unilabs.online

Prohibition didn't stop drinking. It created the mafia. The war on drugs didn't stop drug use. It filled prisons and funded cartels. Banning encryption won't stop secrets. It'll just make criminals out of citizens. This is the oldest pattern in civilization: ban a fundamental human behavior and watch it go underground. The behavior doesn't disappear. It just becomes dangerous, unregulated, and controlled by the worst people instead of the best. Privacy is a fundamental behavior. People have always whispered. Always kept things from others. Always kept parts of their lives separate from other parts. This isn't deviance, it's architecture. The human psyche requires rooms with doors. When governments push to ban strong encryption, mandate backdoors, or outlaw privacy tools, they're not preventing crime. They're creating a world where only criminals have privacy because criminals don't follow bans. Law-abiding people surrender their encryption keys. Criminals don't. Law-abiding people use KYC exchanges. Criminals don't. Law-abiding people comply. Criminals route around. The result? The people who need privacy most - journalists, dissidents, abuse survivors, activists - lose it. The people doing actual harm were never using compliant systems anyway. Every privacy ban is a prohibition. And every prohibition creates the exact underworld it claimed to prevent. The alternative: build privacy into infrastructure so well that it's not a choice. Not a political stance. Not suspicious behavior. Just how the system works. The way cash always worked.

Amazon just confirmed 16,000 layoffs but sources inside are telling me the real story is so much worse Word from three different VPs: the 16K number is just "Phase One" - internal docs show another 14,000 cuts planned for Q2 A director in AWS walked me through their new "efficiency matrix" - entire teams being replaced by 2-3 senior engineers running Claude Sonnet workflows The Alexa division got completely hollowed out. 847 engineers two months ago. 23 remaining after this week. All hardware development moved to a Bangalore team of 31 contractors with Cursor access Here's the sick part: they're making the outgoing engineers document their entire decision-making process into "knowledge transfer sessions" that are being recorded and fed directly into training datasets One L7 told me he spent his final two weeks creating detailed prompt libraries and workflow documentation. Thought he was being helpful for the transition Turns out he was literally training the AI agent that replaced his entire org The contractors offshore are using his exact prompts and shipping features 40% faster than his old team of 12 Americans ever did Internal Slack shows leadership celebrating "operational excellence" while badges get deactivated in real-time They're calling it "right-sizing for the AI era" in the all-hands But the P&L sheets I'm seeing show $280M in salary savings this quarter alone The knowledge extraction is complete If you're still at Amazon and haven't started job hunting, you're already dead

If somebody is telling you Switzerland has great banking they are living in the past.

@pomes_47 @wilderko Yes, but Paraguay did not. With py tax residency, there's still no reporting, because there's nowhere to report to

@wilderko Haven't Georgia implement CRS already?

Paraguay is a great country for tax residency, but for larger amounts, avoid using Paraguayan bank accounts or crypto exchanges/crypto services to avoid surveillance. The limit for crypto transactions is $5,000 per year, after which you must declare it in Paraguay. We recommend non-CRS bank accounts in Kyrgyzstan or Georgia (where you can open one with Paraguayan residency) liberation.services/en/ More information about spying legislation in Paraguay: revistaplus.com.py/2026/03/11/dni… dnit.gov.py/en/web/portal-…

@Polystate_io @wilderko They recently rugpulled bank clients in Cambodia. I would advise strongly against banking in Cambodia

@wilderko Or Cambodian non-CRS bank accounts!
