I study math at uni and I was shocked realizing all my teachers use ubuntu on both their laptop and work desktop
Code and snippets to analyze data work well when you can send chunks of it to multiple servers (think analyzing the effect of weather patterns).
Since a lot of that stuff is running on Linux (similar to cloud computing) it makes sense that people that write function/scripts/utilities would already be comfortable in that environment and use it as their daily driver.
Would meteorologists be writing that stuff or just using it? I would have thought using, but not programming.
Not sure. Like any field I suspect there’s specialties including people who do research/modeling vs consuming that data and advising based on it.
