Hybrid Reasoning Agents: LLM agents that think in latent space, act through text

https://arxiv.org/static/browse/0.3.4/images/arxiv-logo-fb.png
We can build Hybrid Reasoning Agents that bridge latent reasoning and text-based interaction, enabling efficient agentic capabilities. These agents improve performance by 10.4% while reducing tokens, inference time, and costs compared to existing LLM agents and frameworks.

William Gibson and the trademarking of cyberspace

https://colo.to/pix/guell.jpg
The author claims Autodesk trademarked "cyberspace" and William Gibson retaliated by trying to trademark "Eric Gullichsen", but this is a disputed story. The actual reason for Gibson's objection was Timothy Leary's prank, which was later exaggerated into accepted history.

How Postgres DELETE can actually scale

https://cdn.prod.website-files.com/672411cbf038560468c9e68f/6aabf47cc51b3c6da01c94c0_ebec94f2.png
Postgres DELETE has a bad reputation, with many high-performance systems opting to avoid deletes entirely, instead cleaning up data by truncating entire tables or dropping entire partitions. If deletes didn't scale, that would be a shame, because DELETE is far more flexible than dropping partitions or tables, especially when data is heterogeneous and you need to store some items longer ...

A Broadcom 802.11 vulnerability has been present since 2010, affecting dozens of vendors and millions of devices worldwide, allowing for remote code execution and information disclosure. The vendor was aware of the issue but refused to assign a CVE or publicly disclose it until now, leaving many OEMs without patches.

Java sealed classes and exhaustive pattern matching

Java 17 introduced sealed classes to explicitly list allowed sub-types, enabling exhaustiveness checking and compile-time safety guarantees. However, adding a new sub-type can break consumers of the code unless everything is recompiled together.

A new way to think about borrow checking (in reverse)

The author discusses a novel approach to borrow checking in programming languages, where the safety check is performed in reverse. This allows for more efficient and accurate memory safety checks, particularly when dealing with complex data structures and loops.
