2. After 20 years, math couple solves major group theory problem
Total comment counts : 16
Summary
The article discusses the journey of Britta Späth, a German mathematician, who in 2003 encountered the McKay conjecture, a significant unsolved problem in group theory. Initially, Späth aimed to make small contributions to the problem, but it captivated her focus over the years. Her dedication led her to collaborate with Marc Cabanes, another mathematician, with whom she also started a family. Together, they worked on the conjecture which posits that one can understand the complex structure of a group by examining only a small part of it, much like how Eratosthenes estimated the Earth’s circumference from observations in just two cities.
The McKay conjecture, proposed by John McKay in the 1970s, suggests that significant insights into a finite group can be gained by studying its Sylow normalizers. Despite many attempts by mathematicians to prove this conjecture, it remained unsolved until Späth and Cabanes announced their proof after more than a decade of work. Their achievement was celebrated in the mathematical community, with colleagues like Persi Diaconis expressing admiration for their perseverance and success. The article highlights how this proof not only resolved a long-standing conjecture but also deepened the understanding of group theory, an essential area of mathematics dealing with symmetries and structures.

Summary
Summary of the Article on Obscura VPN:
Obscura introduces itself as a pioneering VPN service that ensures maximum privacy and security by design. Unlike traditional VPNs, even those with “no-logs” policies, Obscura does not have the capability to log user activity:
Privacy by Design: Obscura’s infrastructure prevents it from seeing or logging user internet traffic. It uses a system where servers relay encrypted traffic to exit servers without decrypting it, ensuring that neither Obscura nor the exit server (run by Mullvad) can link user identities with their internet activities.
Payment and Anonymity: Users can pay with Bitcoin’s Lightning Network, enhancing anonymity by not requiring personal information like names or email addresses. The login process uses only a randomized account number.
Stealth Technology: Employing QUIC, a protocol used in HTTP/3, Obscura’s traffic blends with regular internet traffic, making it difficult for censors or network filters to detect or block.
Verification and Transparency: The source code is available on GitHub, allowing users to verify the privacy claims. Obscura also plans to offer reproducible builds, ensuring that the software matches the published code.
Pricing and Accessibility: Launched at a promotional rate of $6/month, Obscura supports multiple payment methods, including credit cards via Stripe, though Stripe might require an email for subscriptions.
Technical Setup: The service uses a dual-hop system for enhanced privacy, with one hop for encryption and another for exiting to the internet, ensuring no single entity can see both user identity and traffic.
This article highlights Obscura’s approach to providing a VPN service that prioritizes user privacy and security through technological innovation and transparent practices.
