Comment China's South-to-North Water Diversion (Score 0) 32

When I was in Beijing in 1990s, it was quite dry in the suburb where you could see farm lands. In summer 2024, I visited again and was surprised by how green and dense the vegetation was. Looking up online using AI, based on reports from the Beijing government web site, Beijing's underground water levels have rebounded significantly from historic lows, showing a rising trend. The lowest point was about 25.75 meters in 2015. It has risen approximately 9.64 meters to 16.11 meters by 2021 and continued climbing to roughly 12.83 meters in March 2025. By October 2025, the water table was reported at an average depth of 10.82 meters. This recovery is credited to water conservation efforts and water from the South-to-North Water Diversion Project.

Comment Rust vs C++ (Score 4, Insightful) 77

I have been teaching Rust to college students since 2020. It gets the pointer concept and uses right, i.e. the right (or best so far) balance between correctness and flexibility. In comparison, C++ is all flexibility and no real correctness guarantee. As a result, parallelization for Rust is a small step. For C++, it is almost impossible. Anyone who thinks Rust is equivalent to modern C++ is delusional.

Comment AI is too risky (Score 1) 83

Assume the current AI tool is as good or better than human. What happen in the future when an update of the algorithm or tool, an improvement or twist or fix, leaves a corner case terribly wrong for a small group of patients? AI is the ultimate group-think.

Comment Peer reviews (Score 3, Interesting) 61

I have done many such reviews. Unlike in math, a reviewer can check the logic and derivation fully. In sciences, one can't check the result of an experiment unless one conducts it, which reviewers typically don't do. What they check is whether there is enough information for someone else to repeat the experiment.

The Wuhan Institute of Virology was trying to find viruses of pandemic potential to try to then proactively develop vaccines for them. This involved genetically engineering viruses to see how much they would need to evolve to become really dangerous. We know this because of their papers and grant applications, public record.

So far so good.

Reckless experiments, but not actually a bioweapon. And then via sloppy hygiene it leaked. Very simple. Leaks happen all the time in biolabs.

The technology to do this has only been accessible for a few years, and out pops a super virus.

Where is the evidence of this? Do you know how many lives China lost to SARS and if you do, do you still think the Wuhan lab would treat this with anything but the highest level of security and containment? China, if nothing else (lacking creativity, copying etc etc), can get quality control right.
