On average, I would say a senior would get between 3k and 4k euros in RO, at a regular company. It depends a lot on city too. In bucharest salaries should be higher.
Obviously Amazon thinks that mortages can be paid just by flexing their employee badge.
It's not accurate, at least for RO. According to an official site, 32% of our electricity comes from wind since yesterday. On this site it says it's 0.5%
You don't, it's one of the issues I have, trying really hard to scope the project. I basically try to replicate the features the likes of Greenhouse are selling, obviously on a simpler scale.
Ideally I would prefer to sustain myself from one of these projects. There are a lot of projects that are successful. Sure they aren't making a fortune, but they enough money to support their maintainers.
I'm thinking about starting an OSS project as an alternative to Greenhouse and the likes (applicant tracking software) in written in PHP, as that's my main language at work.
However, I'm a bit relunctant seeing the hate the language gets even though I would use a modern framework like Symfony or API-Platform.
I think having some insulation is better than having none. But yeah, if you want to do it properly, it would cost a lot more.
As for heating your neighbours, a lot of cities have city heating and is paid depending on how many people live in the apartment, so you don't care that much about it. Of course, some folks have gas boilers in their apartment (like me) but it won't make sense financially to insulate the inner walls.
I think it's the same for new buildings here too, if not worse. A lot of regulations aren't actually respected and because a lot of builders left for WE, there's a huge problem with finding skilled workers.
A lot of people in Eastern Europe live in apartments and houses that can be insulated extremely cheap. There are even EU or government programs that make it affordable.
