New algorithm outperforms Dijkstra after 40 years!

EDIT: link to the article https://arxiv.org/abs/2504.17033 For 40+ years, the shortest-path problem (think Google Maps, routing, networks) was dominated by Dijkstra-style algorithms, always hitting the sorting bottleneck. A research team at Tsinghua University just published a breakthrough:
They built a new shortest-path algorithm that avoids sorting altogether, breaking a theoretical barrier thought impossible since the 1980s. Key ideas: - Work in layers instead of strict ordering
- Pick representative pivots (clusters) instead of sorting every node
- Use a few Bellman–Ford–style relaxations to propagate distances
- Runs in O(m log2/3 n) — faster than any sorting-based method It just won Best Paper @ STOC (one of the top CS theory conferences).

- Will this change how we teach algorithms? - Or is it more of a “theory-only” milestone for now?  submitted by /u/Ambitious-Page-5737 (https://www.reddit.com/user/Ambitious-Page-5737)

MCP servers can’t be the future, can they?
https://www.reddit.com/r/programming/comments/1n17vn1/mcp_servers_cant_be_the_future_can_they/

From what I understand, an MCP server is just like a really badly slopped together RPC protocol that gets LLMs to interact with other systems. So…we are just going to run dozens or hundreds of MCP servers locally for our LLMs to access all the tools? This can’t be what AI hypers believe the future is going to be, is it? We are going to burn GPU cycles instead of just making a database call with psql? This can’t be the way…  submitted by /u/kabooozie (https://www.reddit.com/user/kabooozie)

LangChain Open Source Analysis: Understanding the README and First Steps
https://www.reddit.com/r/programming/comments/1n19jo1/langchain_open_source_analysis_understanding_the/

I’m experimenting with a blog format where I break down open source projects in a very simple way — starting from their README, then moving into the code. The first post is about LangChain. I’d love feedback from others who are interested in open source analysis, and I’m also open to suggestions for future projects.  submitted by /u/Programmirowanie (https://www.reddit.com/user/Programmirowanie)
