While any tariffs (even Trump and EU tariffs) are bad, they have a very easy and obvious solution. As you can see, they depend on the tariffs of the other country. No need to sit with Trump at a negotiating table and pretending you're doing diplomacy. Stop vat and tariffs unilaterally, help your people become instantly wealthier and Trump will lower theirs. You don't like American citizens being taxed on imports from Europe. You should more care about European union citizens not being taxed on imports from USA (and everywhere else). You can do it Ursula, go, go, go!

Confession: I wholeheartedly hate Rust. It just sucks. The build system is ok (not great, not terrible) and the fact it can compile into WASM is nice. Everything else just plainly sucks. Otherwise I'm not religious, I can handle and enjoy most languages. When I hear a project is being rewritten in Rust, it's sad news. People waste time on the rewrite instead of the features and it stops being improvable for me. I hope this Rust mania ends soon and we can all go back to nice programmer friendly languages. Rust is computational Marxism.

Unpopular opinion: washing hands is overrated. (Outside of medical setting) We have this magic protection mechanism called the skin. Yes, touching eyes and mouth can spread infections, but it is way less common than people think and especially - washing your hands ten times a day won't help much. Before you wash your hands, you already touched everywhere on your body.

Project with kids? Something like LightningPiggy ( ), but with Cashu and maybe some more interesting interface? NFC, USB text files (probably more difficult) or something similar. A way where you have a feed that you are feeding it Bitcoin, not sending to it. ESP32 cashu client should be easy (micropython?) enough to vibe-code :) Or even more fun - if locked to pubkey (forever), it could be completely offline. Just verifies signatures of paired mint and shows that the keys are locked to pubkey. And then there's a button to dump all tokens for exchange.

Je platba kartou priložením zlatý štandard užívateľského rozhrania? Ale kdeže. Je to fiat. Odovzdanie kľúča a PINu náhodnému terminálu vo večierke vo Vietname, prípadne platba priložením mobilu nám neumožňujú potvrdiť napríklad sumu platby na našom zariadení. Aké máme iné možnosti a prečo to v Bitcoine robíme inak ... CZ: https://www.alza.cz/platebni-site SK: https://www.alza.sk/platebni-siete

ELI5 explanation of an eso level. Please remember the only authoritative ESO level estimator is here: "Imagine your brain is a little rocket ship. And every time someone says something super normal and easy to understand, like '1 plus 1 is 2', your rocket doesn’t even lift off. That’s level 0 — your brain is just chillin’ on the ground, eating cookies." "But then, someone starts talking about gold turning into magic money, or mushrooms that help you think like a wizard, or aliens singing songs through your bathtub faucet — and your rocket goes WHOOSH higher and higher into the sky!" "The eso level tells you how high the rocket goes. Level 0 is like: ‘Facts!’ Level 5 is like: ‘Ooooh magic mushrooms!’ Level 10 is like: ‘ALIENS TALK TO MY TOAST!’" So when someone says something, we just check: Is the rocket still on Earth or is it doing loop-de-loops past Saturn?

Currency reforms and CBDCs Czechoslovakia – Currency Reform of 1953 In Czechoslovakia, a drastic currency reform took place in May 1953 under the communist regime. Old crowns were replaced with new ones at a rate of 5:1 for savings up to 5,000 Kčs, but for higher amounts, the rate was far less favorable, up to 50:1. Key aspect: Citizens could exchange only a limited amount of money, and if they wanted to exchange more, they had to document the legal origin of their income, which was practically impossible, especially for private entrepreneurs or people with savings. Many thus lost most of their wealth, leading to widespread impoverishment. Germany – Currency Reform of 1948 After World War II, in West Germany, a reform in June 1948 replaced the Reichsmark with the new Deutsche Mark. Each resident could exchange only 40 Reichsmarks per person at a 1:1 rate, with the rest of their savings frozen and later partially devalued at a 10:1 rate. Key aspect: The restriction to a fixed amount (40 DM per person) and the need to document income for larger sums meant that those with greater savings (often from the black market or pre-war times) lost most of their wealth. While the reform jumpstarted the economy, it was devastating for many. USA – Nixon Shock of 1971 In August 1971, President Nixon ended the gold standard, decoupling the dollar from gold. This wasn’t a traditional currency exchange, but it devalued money through inflation and eroded purchasing power. Key aspect: While there was no direct requirement to document income or limit exchanges, the indirect consequences—loss of trust in the dollar and subsequent inflation—impoverished residents, especially those holding cash savings. Control over the currency shifted entirely to the state and central bank. CBDC (Digital Euro) and Similarities to These Reforms The digital euro, as a form of central bank digital currency (CBDC), presents a modern parallel to these historical reforms, particularly in terms of control and restrictions. With a CBDC, the central bank (in this case, the ECB) would have direct oversight over every transaction. If it were introduced with rules such as a maximum amount an individual could hold or exchange, or a requirement to document the origin of funds (e.g., when converting cash to digital currency), it would echo past restrictions. Specifically: Need to document income: When introducing a CBDC, governments might require citizens to prove the legality of their savings during the conversion from cash to digital currency, much like in Czechoslovakia or Germany. This could disadvantage people with informal income or savings. Limit on amounts: The ECB could impose caps on holding digital euros (e.g., to combat money laundering), replicating the fixed-sum principle of the German reform. Loss of anonymity: Unlike cash, every transaction would be traceable, increasing the risk of retroactive controls and penalties, thus amplifying state power over individuals—a centralization similar to that seen in the Nixon Shock. The digital euro could resemble these reforms by potentially limiting individuals’ freedom to manage their own money and imposing strict rules, such as the need to document income or caps on exchange amounts. Historically, such measures led to impoverishment, and a CBDC could repeat this problem in the digital age, this time with even greater control over the population. Buy Bitcoin, now. And get friendly with some good proxy merchants.

Veľké menové reformy v histórii často viedli k ochudobneniu obyvateľov, pričom jedným z kľúčových aspektov bolo obmedzenie výmeny peňazí a nutnosť dokladovať príjem alebo vymeniť iba určité množstvo. Pozrime sa na príklady z Československa, Nemecka a USA (Nixonov šok) a potom na súvislosť s digitálnym eurom (CBDC). Československo – Menová reforma 1953 V Československu prebehla v máji 1953 drastická menová reforma pod komunistickým režimom. Staré koruny boli nahradené novými v pomere 5:1 pre úspory do 5 000 Kčs, no pri vyšších sumách bol pomer oveľa nevýhodnejší, až 50:1. Kľúčový aspekt: Občania mohli vymeniť iba obmedzené množstvo peňazí, a ak chceli vymeniť viac, museli dokladovať legálny pôvod príjmu, čo bolo v praxi takmer nemožné, najmä pre súkromných podnikateľov či ľudí s úsporami. Mnohí tak prišli o väčšinu majetku, čo viedlo k masovému ochudobneniu. Nemecko – Menová reforma 1948 Po druhej svetovej vojne, v západnom Nemecku, bola v júni 1948 zavedená reforma, ktorá nahradila Reichsmarku novou Deutsche Mark. Každý obyvateľ mohol vymeniť iba 40 Reichsmark na osobu v pomere 1:1, zvyšok úspor bol zmrazený a neskôr čiastočne znehodnotený v pomere 10:1. Kľúčový aspekt: Obmedzenie výmeny na fixné množstvo (40 DM na osobu) a nutnosť dokladovať príjem pri vyšších sumách znamenali, že tí, ktorí mali väčšie úspory (často z čierneho trhu alebo predvojnových čias), stratili väčšinu svojho bohatstva. Reforma síce naštartovala ekonomiku, no pre mnohých bola likvidačná. USA – Nixonov šok 1971 V auguste 1971 prezident Nixon ukončil zlatý štandard, čím dolár stratil krytie zlatom. Nešlo o klasickú výmenu peňazí, ale o znehodnotenie meny cez infláciu a oslabenie kúpnej sily. Kľúčový aspekt: Tu síce nebola priama nutnosť dokladovať príjem alebo vymieňať obmedzené množstvo, no nepriame dôsledky – strata dôvery v dolár a následná inflácia – ochudobnili obyvateľov, najmä tých, ktorí držali úspory v hotovosti. Kontrola nad menou sa presunula plne do rúk štátu a centrálnej banky. CBDC (digitálne euro) a podobnosť s týmito reformami Digitálne euro, ako forma centrálnej bankovej digitálnej meny (CBDC), prináša modernú paralelu k týmto historickým reformám, najmä v otázke kontroly a obmedzení. Pri CBDC by centrálna banka (v tomto prípade ECB) mala priamy dohľad nad každou transakciou. Ak by bolo zavedené s pravidlami, ako napríklad maximálne množstvo, ktoré môže jednotlivec vlastniť alebo vymeniť, alebo s požiadavkou dokladovať pôvod prostriedkov (napr. pri prechode z hotovosti na digitálnu menu), pripomínalo by to obmedzenia z minulosti. Konkrétne: Nutnosť dokladovať príjem: Pri zavádzaní CBDC by vlády mohli požadovať, aby občania preukázali legálnosť svojich úspor pri konverzii hotovosti na digitálnu menu, podobne ako v Československu či Nemecku. To by mohlo viesť k znevýhodneniu ľudí s neformálnymi príjmami alebo úsporami. Obmedzenie množstva: ECB by mohla stanoviť limity na držbu digitálneho eura (napr. kvôli boju proti praniu špinavých peňazí), čím by zopakovala princíp fixných súm z nemeckej reformy. Strata anonymity: Na rozdiel od hotovosti by každá transakcia bola sledovateľná, čo zvyšuje riziko retroaktívnych kontrol a sankcií, čím by sa posilnila moc štátu nad jednotlivcami – podobná centralizácia sa prejavila aj pri Nixonovom šoku. Digitálne euro by mohlo pripomínať tieto reformy v tom, že by potenciálne obmedzilo slobodu jednotlivcov v nakladaní s vlastnými peniazmi a zaviedlo by prísne pravidlá, ako napríklad nutnosť dokladovať príjem alebo limity na výmenu. Historicky takéto kroky viedli k ochudobneniu a CBDC by mohlo tento problém zopakovať v digitálnej ére, tentoraz s ešte väčšou kontrolou nad obyvateľstvom.

AlmaLinux elevate is amazing. They added support for encrypted volumes now. I had just below five hours of sleep instead of pulling an all nighter. Three servers upgraded, one of them is a virtualization machine.. If you have rhel derivative, especially 7-based, you can in place upgrade to AlmaLinux 8 or 9.
