It’s hilarious how the “I LOVE SCIENCE” crowd refuses to apply scientific taxonomy classifications to humans for purely religious/idealogical reasons

Realities of being a man:
1. Nobody cares until you are rich or dead.
2. You have to provide something, then you get love in return.
3. You are born with no value. You have to build yourself up.
4. Your pain is your problem, you have to deal with it.
5. Nobody respects you unless you are competent.
6. If you are weak, society will crush you.
7. Nobody is coming to save you. Not a woman. Not your friends. Not the system.
8. Your usefulness is how most people measure you.

Chinese researchers have developed the best shortest-path algorithm in 41 years!
Dijkstra’s Algorithm has been the undefeated king of the shortest path for over 40 years.
Whether you’re using Google Maps, booking a flight, or routing internet packets, Dijkstra is the engine running in the background.
Since 1984, textbooks have taught that its efficiency was hit by a "sorting barrier."
To find the shortest path, you have to sort the points by distance. And sorting has a mathematical floor you can’t cross.
Until now.
A research team from Tsinghua University just published a paper that shatters the 41-year-old record.
They proved that Dijkstra is not optimal.
By combining the logic of the Bellman-Ford algorithm with a revolutionary "recursive partial ordering" method, they figured out how to find the path without fully sorting the nodes.
The results are a massive shift in theoretical computer science:
- The first deterministic improvement to the Single-Source Shortest Path (SSSP) problem since 1984.
- A new time complexity of $ O(m \log^{2/3} n)$, officially beating the long-standing $ O(m + n \log n)$ limit.
- On massive sparse graphs (like the web or global logistics), this means finding the best route significantly faster than previously thought possible.
For four decades, the greatest minds in algorithms believed this limit was absolute.
Last year, even the legendary Robert Tarjan won an award proving Dijkstra was "optimally efficient" at sorting distances.
Tsinghua’s answer? Stop sorting.
The world’s most settled problem is suddenly wide open again.
If we can break a 40-year-old law in basic graph theory, what other "impossible" speed limits are waiting to be crushed?
Readers added context they thought people might want to know
In real world testing it was found to be slower than Dijkstra.
“We compare these implementations against Dijkstra's algorithm on sparse random graphs, grids, and U.S. road networks[...] Dijkstra's algorithm remains 3 to 4 times faster in all tested scenarios.” arxiv.org/abs/2511.03007

USG "Hey China, can you submit your open models for testing before release?"
China "Oh, go right ahead. It's available online for anyone to test"
USG "...No I mean like submit it to us before releasing it online"
China "Like I said, it's available online. Do you not know how to download open models?
USG "Of course we do, but before publicly making it available for everyone we want you to submit it to us exclusively for safety testing"
China "Oh, oh I see. No."
USG "...If you don't cooperate we may have to restrict access to your models"
China "How?"
USG "By forbidding our enterprises from using them"
China "OK, force them to pay for expensive tokens. I don't care. Nice talking to you"

Staff "Sir China won't cooperate"
President "Xi is a tough cookie"
Staff "Sir, if we don't safety test Chinese open models, but safety test the domestic open source, we will be giving China an unfair advantage"
President "Fine, just safety test the closed ones. They're the ones begging for it"

USAID money funded coronavirus research in China that killed millions of people
.@RandPaul Asks Samantha Power: 'Did USAID Fund Coronavirus Research In Wuhan China?'
"Should we be funding the Academy of Military Medical Research in China? ...Some of the research proposals in 2018 were the Wuhan Insitute of Virology asking for money to create a virus with a furin cleavage site. A SARS-like coronavirus with a furin cleavage site. That's exactly what COVID-19 turned out to be.
So we want to know if there were other research proposals you either granted or denied that were in the same vain as creating viruses that could have become COVID-19. We can't tell because you won't give us information... I now have 25 Senators that have sent you a letter, and you aren't responding... You are being dishonest."
