lucioperca··on SymPy: Symbolic Mathematics in Python
I guess a hypermodern solution would be to produce the parts of the C code with CI/CD from the SymPy Code.
lucioperca··on CRE vet says 30% of office buildings are 'basically worth nothing'
High density high quality housing with good public transport links would be the way to go.

lucioperca··on Solar and battery to make up 81% of new US electric-generating capacity in 2024
Dry cooling tower exists but they are more expensive. Natural cooling with the evaporation eventually runs into the problem due to built-up of salts which forces you to replace non-evaporated cooling water with fresh river water and lets you dump the heated water into the river (which is limiting factor due to environmental concerns). The less water is flowing and the higher the temperature of the river are the sooner this point is reached

There is still plenty of water, the problem is that you have to limit heating the river. With a cooling tower can cool with or without evaporating water depending on the design but always without heating the river. But it is cheaper to directly dump the heat into the water.

Big use-case, problem is that in case of fire lots of dioxins are produced.

lucioperca··on Will satellite megaconstellations weaken earth's magnetic field?
Why not use this energy for mining? What is the terminal velocity anyhow?
lucioperca··on Starlink's laser system is beaming 42 petabytes of data per day
Well maybe it makes sense for US costumer to send their traffic down from Starlink in Canada and then via fiber to the USA? I do not really see the problem if the traffic is encrypted and forwarded.

Of course Emacs has a mode for it:

lucioperca··on Study finds that once people use cargo bikes, they like their cars much less
City does a reasonable jobs getting rid of ice and snow. My guess the increase is not higher as with other modes of transportation.
lucioperca··on Think of your home as (small) profitable power plant
Yes, cost for infrastructure like sewer, water, electricity is much more expensive for low density city parts compared to dense ones. But this is not reflected on the billing. Apart from the needed streets there is a lot other cost like health care which comes with car centered living.

Weather should work for most places in the world: https://www.youtube.com/watch?v=URMQ0d286hY

Well, basically it all comes down to density and infrastructure if people will use other means of transportation. Bicycle accounts for 1/3 of all trips city wide.

Forcing people to active by either (partly) walking or cycling has great benefits for the public.

These suburbia homes are still pretty bad deal for the public. Lots of infrastructure cost come with them like car infrastructure etc.
lucioperca··on Study finds that once people use cargo bikes, they like their cars much less
I use my cargo bicycle everyday because I never bothered to buy a car after Uni and cars where I live would be a major pain because of traffic and parking near my flat. I do have car sharing though. I would not consider me a bike enthusiast, but I like to get my metabolism going in the morning compared to car travel. Weather is no problem, you just need to dress accordingly. Many people in my city do cycle everyday. I play basketball twice a week and 80% of the players arrive by bicycle.

I use my cargo bicycle every day for everything even if I would not need it. The cargo use case is for carrying children around (e.g. kindergarden) or shopping. I do not have a car, but I have another bicycle but I use that on very few occasions like train travel.
lucioperca··on EU chip goal 'unrealistic' says ASML CEO
Does not work like that, EU has big stake in the EUV-tech. I see no problem in forcing ASML to build a fab in Europe.

"All metrics of scientific evaluation are bound to be abused. Goodhart's law [...] states that when a feature of the economy is picked as an indicator of the economy, then it inexorably ceases to function as that indicator because people start to game it."

lucioperca··on Energy crisis: How living in a cold home affects your health
Well one problem is the viscous cycle. Because heating less people will open the window less which means it gets more humid and mold starts growing. People should install hygrometer and keep it in the save level. Then low room temperature should be fine.
