Computador quântico: o que realmente ameaça o Bitcoin?
O Bitcoin vai morrer por causa do computador quântico? 🤔🚀
• Contexto rápido:
- A Carol comentou sobre o medo do computador quântico e as soluções sugeridas por Satoshi.
• O que isso significa na prática:
- SHA256 é muito mais forte que ECDSA. 🔐
- Se um hash ficar fraco, troca-se o hash. 🔁
- Se um algoritmo de assinatura digital ficar fraco,...

Git 3.0 is coming. Are your tools ready? 🛡️
In our latest SmartGit Preview 26.1.011, we’ve officially introduced #Git 3.0 compatibility, targeting the 2 biggest architectural changes:
✅ SHA-256 Support: Moving beyond SHA-1 to ensure long-term cryptographic security and collision resistance.
✅ Reftable Support: A new storage format for refs that solves the "thousands of branches" performance bottleneck. No more scanning thousands of tiny files in .git/refs.

1/2 Exciting news: we just published a new paper: "Preimage attacks on round-reduced MD5, SHA-1, and SHA-256 using parameterized SAT solver", by Oleg Zaikin
If you are interested in security, cryptology, or Constraint Programming, definitely give this paper a read!

Git 3.0 is on the horizon, and it is bringing some of the biggest changes we have seen in a decade. I recently followed a deep dive into the future of Git based on Patrick Steinhardt’s session at FOSDEM 2026. The focus is shifting from just maintaining the tool to evolving it for massive scale and better developer experience. Git 3.0 is about making the tool more robust for the next ten years of software development. Author: ennael Source: OSSFlow Link in the comments
Thanks to @Monorepo for doing most of this, which needed changes to both the release process and the website: releases since 13th January now show SHA-256 checksums instead of MD5!
Release of hshwd
hshwd is an open-source offline tool that generates strong, unique passwords from weak ones in a deterministic way, using the properties of hash functions.

A lot has happened since I last worked on Moxxy, the most important for us today being the release of Material 3 Expressive. I personally love the direction Google is taking by making the UI fun for users (and designers!) while still focusing on and improving ease of use and readability.
[Перевод] Пишем свой git: минимальная реализация на Rust
Контроль версий долгое время был для меня «чёрным ящиком»: я не понимал, как именно хранятся файлы, как формируются diff’ы и из чего состоят коммиты. А поскольку я люблю изобретать велосипеды, почему бы не попробовать реализовать git самому?
