String Theory Inspires a Brilliant, Baffling New Math Proof

💥 Discover this must-read post from Hacker News 📖 📂 Category: 💡 Here’s what you’ll learn: In particular, Katzarkov wanted to break the mirror image’s curve count into pieces, then use the mirror symmetry program to show that there was a corresponding way to break up the four-fold’s Hodge structure. He could then work with these pieces of the Hodge structure, rather than the whole thing, to show that four-folds can’t be parameterized. If any one of the pieces couldn’t be mapped to a simple 4D space, he’d have his proof. But this line of reasoning depended on the assumption…

The Coming Need for Formal Specification

The Coming Need for Formal Specification

🔥 Check out this insightful post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: In late 2022, I had a conversation with a senior engineer on the coming problem of “what to do when AI is writing most of the code”. His opinion, which I found striking at the time, was that engineers would transition from writing mostly “implementation” code, to mostly writing tests and specifications. I remember thinking at the time that this was prescient. With three years of hindsight, it seems like things are trending in a different direction. I thought that the reason that…

Google Removes Sci-Hub Domains from U.S. Search Results Due to Dated Court Order * TorrentFreak

💥 Read this must-read post from Hacker News 📖 📂 Category: 📌 Here’s what you’ll learn: Home > Anti-Piracy > Site Blocking > Google has removed dozens of new Sci-Hub domain names from its search results in the United States.

In 2017, American Chemical Society (ACS), a leading source of academic publications in the…

💥 Check out this awesome post from Hacker News 📖 📂 Category: ✅ Here’s what you’ll learn: This title is an obvious nod toTo encrypt email in 1998 you’d run GnuPG from a terminal, importing the recipient’s public key into your local keyring then copying your email text into a file then encrypting the file for that public key: gpg -e -r alice file. Finally you’d copy the encrypted message into your email client and send it out.In 2025, it’s pretty much the same. In some respects, it’s worse:It feels like fewer people care about email encryption today than they…

Rethinking sudo with object capabilities · Ariadne’s Space

💥 Explore this must-read post from Hacker News 📖 📂 Category: 💡 Main takeaway: I hate sudo with a passion. It represents everything I find offensive about the modern Unix security model: like su, it must be a SUID binary to work it is monolithic: everything sudo does runs as root, there is no privilege separation it uses a non-declarative and non-hierarchical configuration format leading to forests of complex access-control policies and user errors due to lack of concision it supports plugins to extend the policy engine which run directly in the privileged SUID process I could go on, but…
