I'm using Python script in my Phoenix app (not Livebook). I hoped Pythonx would solve all the issues associated with System.cmd, but as you can imagine, I have more than one user.
I believe mussels are now (2025) protecting more cities.
What is cool about Warsaw is the TAWARA-RTM (TAp WAter RAdioactivity Real Time Monitor.
"Warsaw as the first city in the world is protected by a comprehensive system that is capable to monitor in real-time radioactivity of municipal water and by an innovative spectroscopy system capable to identify any detected contaminants"
It's likely already planned, but testing for radioactivity in wastewater too would likely detect any released radioactive material that didn't impact tap water.
Interestingly, I got substantially different results depending on whether I used chrome with my typical extensions or not. Looking at the flamegraph, I don't seem to see the full picture of why there's such a substantial difference. Bitwarden/React Developer tools (the 2 primary extensions I use) don't seem to make enough of an impact to account for the roughly 40% performance increase seen without them. The browserbench javascript accounted for ~38.6% of the overall time taken for the benchmark, but the sum of my extensions was only 6.5%. I'm not incredibly familiar with browser performance profiling, so there's probably more to the story.
