Whoa, 3 million EUR! Nice!

I hope they'll fund more things that aim to break cloud/vendor lock-in.


Ye, because fossil fuel extraction and refining for lifetime of car is all roses and sunshine.


Isn't this just cycling carbon in ecosystem? Same as planting tree on 100 year scale is pointless... I would imagine that hydro is ~neutral on 100 year scale, while coal is not, since we introduce carbon into ecosystem. What am I missing?


Produces methane, not CO2 because the plants decompose in an oxygen free environment. Because of the cycling of water throughout the year, during the dry seasons plants grow along the shoreline (which varies considerably because of the use of hydro), and then are covered up during the rainy season. This can be hundreds of kms every year.


Methane isn't great, but unlike CO2 is has a pretty short lifetime in the atmosphere (just 12 years). So the impact of the methane release from hydro is basically static rather than an ever increasing problem.


This is not true! Methane is not only 84x more warming than CO2, it is at a record high at <1900ppb and rising, the current level is higher than the RCP 4.5 warming scenario by the IPCC (which is in the middle level of a warming scenario), and there is evidence that the atmospheric lifespan might be increasing


This is what my quick google turned up [1].

> A molecule of methane traps more heat than a molecule of CO2, but methane has a relatively short lifespan of 7 to 12 years in the atmosphere, while CO2 can persist for hundreds of years or more.

Doesn't mean it's correct though so I'd be happy to see different thinking on this.

That being said, IIRC, isn't one of the models for the increasing methane the melting permafrost [2]? So the levels are somewhat expected to be increasing pretty rapidly as a result of global warming in general.

https://climate.mit.edu/ask-mit/why-do-we-compare-methane-ca... "Over 20 years, the methane would trap about 80 times as much heat as the CO2. Over 100 years, that original ton of methane would trap about 28 times as much heat as the ton of CO2."

So converting a bunch of atmospheric CO2 to methane evey year is not good.


Well, shoot, that's awful.


It's continuously releasing methane, and methane degrades into.... CO2.

> So the impact of the methane release from hydro is basically static rather than an ever increasing problem.

You can also say the same thing about the coal plant.


Eco probably means ecosystem, which I assume it means lack of UI Controls like Maps view, Graph/Charts for visualizing data, Date pickers and other stuff they you can get from vibrant UI ecosystem. But I think some of this stuff is already handled in Avalonia ecosystem like https://github.com/Mapsui/Mapsui, https://github.com/beto-rodriguez/LiveCharts2 and few others...


See also https://scottplot.net/ although it's not avalonia specific, it just has an avalonia option.


My biggest problem with solar and storage is not day/week energy management we can solve that easy, add more batteries, pumped hydro, use car batteries, incentivize customers to use electricity when sun is up... All easy problem compared to seasonal storage.

Where do we get enough renewable electricity on cloudy week in December? Synthetic gas/oil produced in summer? Anything more promising?


There are a few technologies on the horizon. Using excess energy during the summer to produce a fuel, like you said, is one option. Hydrogen has been considered, but storing it long term is difficult. Another option is ammonia, although it’s toxic and corrosive, and although it produces no CO2 when burned, it still produces NOx, a potent greenhouse gas.

There are technologies on the horizon that could fill the long term storage needs for winter power. Lithium Ion, although great for mobile technologies, is not ideal for grid scale storage. It can’t store power for long. But other chemistries such as vanadium flow batteries and iron air batteries can discharge longer, and they can store power for far longer.


Use energy with atmospheric 3(C02) + 8(H20) -> C3H8 + 7(O2)


For one thing, we could overbuild (cheap) solar. A big portion of summer solar production might be curtailed... and that might be okay.


Well there is also software... I really liked go-eCharger HOME+ 11kW, because it has 3-phase "European connector" and I can go almost anywhere in europe take it with me and charge there... I usually take it with me when I go to my parents so I don't have to stop on way at fast charger... Anyway.. I paid 650EUR, well above price of parts cost... But mobile app and firmware keep getting updated and it keeps getting features like "charge from solar" better scheduler, also supports multiple chargers to limit total amps...


I will never forget something I read in his "Hit Refresh" book(I'm Microsoft employee)... He wrote something along the lines, Office should write best app for iPhone, Mac or even Linux if that helps them grow. They should not help Windows sell Windows copies by doing better Office features on Windows, it is up to Windows team to make Windows best operating system, it should not rely and keep back Office team... This makes Windows and Office better, because it allows Office to be free and do what they need to grow, and it forces Windows to improve OS and not rely on others... Just one example where CEO can help teams grow...


That's a nice vision, but as someone who transitioned from a windows to mac a few years ago, I'm sad to report that reality isn't anything like it. Office for mac is lightyears behind what windows has. Both excel and outlook miss critical features (just last week I was looking to change the background of an email - seems that's impossible on mac), or are so much worse in terms of performance (~20mb file with pivot tables) that I'm not sure if I'm running Excel on my m1 mac or if it's a raspberry pi.


That's definitely a shift from the "platform" thinking Microsoft had, thanks for the inside view.


It's not like MS could do any other thing after being wiped out of the smartphone market. Locking Office to Windows in an age where virtually everybody is using a smartphone or a tablet with either Android or iOS is useless. The situation of Office in either Mac or Linux never improved, it just got turned into a cloud service like almost any other software suite and tried to cash in the legacy name to compete with Google Docs and Zoho. I don't really see any brilliant move there.


'eat your own lunch before someone else does'


C# design team is ~5 talented well paid engineers who think how to improve language for past 20 years, every week and don’t let flawed features in and can spend years on how to add async/await, nullables, SpanT and many other features so whole language makes sense and is joy to use. And they have another ~20 engineers implementing features in Roslyn making sure performance of IDE and compiler is acceptable and bug ~free. Unfortunately not many languages can afford that…


This is to the point! That is why C# evolved so quickly and does not spiritually or factually broken.


So my house is worth 500k, someone looking for house in range 500k-700k, really really likes my house and just kicks me out for 750k? Sounds like terrible idea.


If you really don't like the idea of that happening, you can always self-declare a higher value. Then, not only is it less likley someone chooses your land to buy, but also if it does happen you get more compensation. But then you'll also have to pay matching higher property taxes.


I just wish it displayed buildings at zoom 16(today at 17, while default OSM renderer at 15). And similar for addresses displayed currently at 19, I wish it was at 18, while OSM default renderer displays at 17.
