I think on an iPhone it’s impossible to stop for exactly 0.37s. 0.36 yes, 0.38 too but not 0.37. Why?

I didn't know the world largest offshore wind farm Dogger Bank is being built off the coast of Yorkshire, 4GW!!! It's huge, so cool

How much more efficient have supercomputers become over the last 5 years? Just analysed the top 100 of top500.org : 4x for the most efficient supercomputers in the world, what was top in 2020 is now at the bottom of that Green100 list. Total energy consumption has increased nevertheless

Just a funny little 1D shallow water model using Julia, Makie, and Pluto!

GeoMakie & GLMakie usage in SpeedyWeather. Interactive climate modelling yay! Here just visualising the HEALPix grid

You think ripples in spectral models are weird? Yes, step functions in spectral models are represented with many "weird" oscillations. Sea level will be negative next to big mountains, etc. But that's just the equivalent of representing something smooth with little discrete steps, which arguably 🧵

Is it professionally acceptable to not have MS Word/Powerpoint/Excel etc and ask for other formats? Maybe just me but I find this software exceptionally fragile: A powerpoint presentation created with powerpoint cannot be opened with powerpoint with a hint to open it with powerpoint, wut???

Closed my spotify account as other music streaming services like Deezer pay 2x more to artists and don't invest into AI weapons like the Spotify CEO does. Consumer choices are important!

@zacklabe.com Looking at your awesome graphs, why does the Arctic freeze/melt at similar rates (~6 months of freezing then ~6 months of melting) but Antarctica melts considerably faster (in ~5 months) than it freezes (in ~7 months)?

First attempt at writing a sea ice model 🧊🌊 Only uses sea ice concentration not thickness so there is not enough "memory" of thick ice to retain some sea ice cover during summer. Not bad for zero tuning though, I find! Will be in the next release of SpeedyWeather github.com/SpeedyWeathe...

Daily reminder in case you drive and forgot that cars don’t just ruin cities but also occasionally kill kids.

Even calling 20mph a safety zone. I don’t know anyone who would be safe if hit by an SUV at 20mph. Maybe you don’t die, hurray, is that how low the bar is?

SpeedyWeather's `globe` function can now also visualise any data the model simulates without interpolation on the native grid! Simulate, visualise, zoom, rotate, zoom, you do you! it's a bit laggy but that's because I was recording too ... github.com/SpeedyWeathe...

SpeedyWeather reinvents how we do atmospheric modelling. Traditionally that's just compute. I think that's also interactivity, extensibility, ease of use, aaaand visualisation. Newest kid on the block, the `globe` function powered by GLMakie+GeoMakie, visualising the grid the model uses

Also "you're not allowed to use green" haha this is the deuteranopia version of that plot 🙈

Maybe people that prefer non-uniform colourmaps would also do this?

Subtle variations become subjective though and that is the problem. Here are two plots of a temperature section in the Atlantic. Depending on the colourmap (with jumps that the author subjectively chose!) you get a very different idea of what "belongs together" and what not.

Everytime I open one of these I enjoy seeing EU law impacting British life despite Brexit. So much about “taking back control” haha.
