lauri_jo··on Europe’s next-generation weather satellite sends back first images
This data is from the third generation of Meteosats, which are the European meteorological satellites. A lot like GOES in the north-America. The main improvement is really significant improvement in resolution. The resolution is, depending on the channel, 9 times better than in the second generation. The main improvement in forecasting comes due to better information in the initial condition of the numerical weather prediction, but it is hard to quantify in advance. I'd be surprised if MAE, over the 15 days the prediction spans, would improve more than 0.1 C, if we talk about the raw prediction. There are plenty of things that this data is used for, but I would say that improved nowcast of cloud coverage, and energy production related parameters are likely to benefit most from the improvement in resolution.
lauri_jo··on What influence has the BBC had on history?
It seems somewhat obvious that more democratic Russia would be in the interests of the rest of the Europe. Similarly self evidently, the former KGB is against it. Freedom of press is rather important part of democracy, and the state controlled media is an important part of an authoritarian play book.

The lack of democracy in Russia has now ended up costing millions of lives and trillions in damages, so maybe we should have actually invested more?

lauri_jo··on Converting a Go-Kart into a Deathtrap
That reminded me of the rocket nozzles we designed in my supersonic fluid dynamics course. It's a shame my kids have already outgrown the go-kart stage.
lauri_jo··on This house does not exist
Not sure if my experience generalises well, but a few of those houses generated were impossible to build.
