Unfortunately, all I have to say about the new @FrameworkPuter is negative. Criticisms below: 1. I do not have one. 2. I cannot get one for a very long time. 3. My kids have said this is an embarrassment to the family.

Dzień dobry. Takie tam w rocznicę wejścia Polski do UE.....😁

That's understandable. 🐧

Sci-Hub is an evil website that pirated 85M+ research papers and made them freely available And now they've added AI to their database to make Sci-Bot. It answers your questions using latest, full-text articles. But DO NOT use it. We should all try to make billion-dollar academic publishers richer. I'm putting the link below so you know how to avoid it.

@The_Davos_Man The word "purity" is not there.

This is the new commie propaganda talking point on Ukraine. In case you encounter it, here is the fact: Article 16 of the Ukrainian constitution is about overcoming the legacy of the Chernobyl disaster on public health, in particular the threat of cancer through radiation.

@GM_Crius @AlexAuroraDev @peterktodd @litecoin China adds 1/10 of that power to their grid daily.

@pepesza_eth @AlexAuroraDev @peterktodd @litecoin You could, but you'd have to control 51% of the mining power. The hash rate is currently 946EH/s. Half would be 473EH/s. It would cost $3 Billion dollars just to purchase the ASIC hardware required to get to 50%. Then you need power/infrastructure/cooling.

10h ago @litecoin experienced a coordinated attack on the chain that resulted in 13 blocks reorg that took more than 3h to generate. During this time attackers were performing double spend attacks on multiple cross-chain swapping protocols. We are investigating the situation.

@HOomanAi9 @Whiledvid Garbage take. Ukrainians are dying for the future of their country. Russians are dying for cash.

@Whiledvid Fuck man…a lot of sons brother and humans are dying for nothing…just for bullshit politicians 😞

As you become an adult, you realize that things around you weren't just always there; people made them happen. But only recently have I started to internalize how much tenacity *everything* requires. That hotel, that park, that railway. The world is a museum of passion projects.

@MateuszSno97831 @Przemek_Zaba @jakubwiech Poszukaj "Ember Global Electricity Review 2025". I pooglądaj jak wygląda krajobraz mocy wytwórczych w Chinach i na świecie.

@Przemek_Zaba @jakubwiech Idź do wiecha i razem poopowiadajcie sobie te bajeczki.

Albo ludzie, którzy piszą na serio takie rzeczy. Kochani. Opisujecie bardzo, bardzo rzadki przypadek awarii źródła praktycznie bezemisyjnego (intensywność emisji: 11 gramów CO2/kWh). To jest wypadek i usterka. Jednocześnie nie macie problemu z używaniem źródeł energii, które pracują tylko dlatego, że NIEUSTANNIE COŚ SPALAJĄ. Taka Elektrownia Bełchatów spala jedną tonę węgla CO SEKUNDĘ (intensywność emisji: 1200 gramów CO2/kWh). Naprawdę, znajmy proporcje.

@NathanWorsley_ Security risk aside, person you are interviewing is not the same as one that will „work” for you later. And even that one will share his attention between 5 different projects.

I have had this exact situation happen in job interviews Sucks because they seem like great developers. There is always the urge to hire them anyway and try to sandbox their work, but the risk is too high

Now I'm ready to write the actual implementation.

@secure_overflow @prywatnik Akurat tamte portfele nie są do złamania, bo znany jest tylko hash klucza publicznego, a nie sam klucz. Ale jest pełno portfeli które już coś podpisały.

@prywatnik No jakby ktoś złamał pierwszy portfel Satoshi-ego… ojojoj kiepsko by było 😱

Google twierdzi, że złamanie kryptografii Bitcoina może wymagać znacznie mniejszego komputera kwantowego niż dotychczas zakładano. Pierwszy atak kwantowy na kryptowalutę może nie zostać ogłoszony. Może po prostu pojawić się na blockchainie. Każdy będzie widział efekt, choć niekoniecznie będzie wiadomo kto przejął kasę. Przy założeniach dotyczących sprzętu nadprzewodzącego pełny atak mógłby zająć do 23 minut. Jeśli maszyna wcześniej wykona pierwszą połowę obliczeń, czas skraca się do 12 minut. Ethereum jest bardziejpodatne. Jego model kont sprawia, że każde konto, które wysłało choć jedną transakcję, trwale ujawnia swój klucz publiczny. Bitcoin daje użytkownikom wybór. Większość z niego nie korzysta. Google nie opublikowało metody ataku - tylko kryptograficzny dowód, że taka metoda istnieje. I że go mają. Uzasadnienie: ujawnienie szczegółów byłoby nieodpowiedzialne, choć żaden działający komputer kwantowy nie istnieje i w przewidywalnej przyszłości go nie będzie. To osobliwa logika.

@panoramix754 @prywatnik Tak. NIST opublikował rekomendowane PQ algorytmy. Signal już jest PQ-secure (WhatsApp też). Ethereum jest w trakcie prac nad zmianami. Świat nie czeka na Bitcoin.

@prywatnik Łamanie kryptografi Bitcoina to mem . Złamanie algorytmów Bitcoina komputerem kwantowym oznaczałoby zagrożenie dla wszystkich systemów opartych na podobnej kryptografii asymetrycznej, takiej jak RSA czy ECC. Dotyczyłoby to kluczy publicznych, podpisów cyfrowych

Today is a monumentous day for quantum computing and cryptography. Two breakthrough papers just landed (links in next tweet). Both papers improve Shor's algorithm, infamous for cracking RSA and elliptic curve cryptography. The two results compound, optimising separate layers of the quantum stack. The results are shocking. I expect a narrative shift and a further R&D boost toward post-quantum cryptography. The first paper is by Google Quantum AI. They tackle the (logical) Shor algorithm, tailoring it to crack Bitcoin and Ethereum signatures. The algorithm runs on ~1K logical qubits for the 256-bit elliptic curve secp256k1. Due to the low circuit depth, a fast superconducting computer would recover private keys in minutes. I'm grateful to have joined as a late paper co-author, in large part for the chance to interact with experts and the alpha gleaned from internal discussions. The second paper is by a stealthy startup called Oratomic, with ex-Google and prominent Caltech faculty. Their starting point is Google's improvements to the logical quantum circuit. They then apply improvements at the physical layer, with tricks specific to neutral atom quantum computers. The result estimates that 26,000 atomic qubits are sufficient to break 256-bit elliptic curve signatures. This would be roughly a 40x improvement in physical qubit count over previous state-of-the-art. On the flip side, a single Shor run would take ~10 days due to the relatively slow speed of neutral atoms. Below are my key takeaways. As a disclaimer, I am not a quantum expert. Time is needed for the results to be properly vetted. Based on my interactions with the team, I have faith the Google Quantum AI results are conservative. The Oratomic paper is much harder for me to assess, especially because of the use of more exotic qLDPC codes. I will take it with a grain of salt until the dust settles. → q-day: My confidence in q-day by 2032 has shot up significantly. IMO there's at least a 10% chance that by 2032 a quantum computer recovers a secp256k1 ECDSA private key from an exposed public key. While a cryptographically-relevant quantum computer (CRQC) before 2030 still feels unlikely, now is undoubtedly the time to start preparing. → censorship: The Google paper uses a zero-knowledge (ZK) proof to demonstrate the algorithm's existence without leaking actual optimisations. From now on, assume state-of-the-art algorithms will be censored. There may be self-censorship for moral or commercial reasons, or because of government pressure. A blackout in academic publications would be a tell-tale sign. → cracking time: A superconducting quantum computer, the type Google is building, could crack keys in minutes. This is because the optimised quantum circuit is just 100M Toffoli gates, which is surprisingly shallow. (Toffoli gates are hard because they require production of so-called "magic states".) Toffoli gates would consume ~10 microseconds on a superconducting platform, totalling ~1,000 sec of Shor runtime. → latency optimisations: Two latency optimisations bring key cracking time to single-digit minutes. The first parallelises computation across quantum devices. The second involves feeding the pubkey to the quantum computer mid-flight, after a generic setup phase. → fast- and slow-clock: At first approximation there are two families of quantum computers. The fast-clock flavour, which includes superconducting and photonic architectures, runs at roughly 100 kHz. The slow-clock flavour, which includes trapped ion and neutral atom architectures, runs roughly 1,000x slower (~100 Hz, or ~1 week to crack a single key). → qubit count: The size-optimised variant of the algorithm runs on 1,200 logical qubits. On a superconducting computer with surface code error correction that's roughly 500K physical qubits, a 400:1 physical-to-logical ratio. The surface code is conservative, assuming only four-way nearest-neighbour grid connectivity. It was demonstrated last year by Google on a real quantum computer. → future gains: Low-hanging fruit is still being picked, with at least one of the Google optimisations resulting from a surprisingly simple observation. Interestingly, AI was not (yet!) tasked to find optimisations. This was also the first time authors such as Craig Gidney attacked elliptic curves (as opposed to RSA). Shor logical qubit count could plausibly go under 1K soonish. → error correction: The physical-to-logical ratio for superconducting computers could go under 100:1. For superconducting computers that would be mean ~100K physical qubits for a CRQC, two orders of magnitude away from state of the art. Neutral atoms quantum computers are amenable to error correcting codes other than the surface code. While much slower to run, they can bring down the physical to logical qubit ratio closer to 10:1. → Bitcoin PoW: Commercially-viable Bitcoin PoW via Grover's algorithm is not happening any time soon. We're talking decades, possibly centuries away. This observation should help focus the discussion on ECDSA and Schnorr. (Side note: as unofficial Bitcoin security researcher, I still believe Bitcoin PoW is cooked due to the dwindling security budget.) → team quality: The folks at Google Quantum AI are the real deal. Craig Gidney (@CraigGidney) is arguably the world's top quantum circuit optimisooor. Just last year he squeezed 10x out of Shor for RSA, bringing the physical qubit count down from 10M to 1M. Special thanks to the Google team for patiently answering all my newb questions with detailed, fact-based answers. I was expecting some hype, but found none.

@StawowyGrz57634 @DydynskaEliza Wartość mieszkań krakowian nie jest zbyt ważnym wskaźnikiem bo mają zamiar w nich mieszkać.

@DydynskaEliza Szanowna Radna, jak coś publikujesz to bądź precyzyjna. Odniosłem się do tego, że w Krakowie jest około 70 000 mieszkań będących pustostanami. I co się stanie z wartością mieszkań krakowian gdy pojawi się taka ilość na rynku. Podreśliłem, że jestem przeciwnikiem katastralnego.
