I guess Greek house building was several decades ahead of Belgian house building then, because I’ve yet to see a pre-war house with cavity walls. I guess the cheap coal heating and lack of a need for cooling must have something to do with it.

The 100 years old brick buildings don’t have any voids. That only started post-WWII when ventilation became a real concern.

But even then those houses are likely to have wooden floors and more modern drywall remodeling in some areas. My house is hurricane-proof but not rat-proof.

It can do both, lossiness is toggleable.

If you’ve seen a picture on Lemmy, you’ve almost certainly seen a WebP. A fair bit of software – most egregiously from Microsoft – refuses to decode them still, but every major browser has supported WebP for years and since superior data efficiency compared to JPG/PNG means is already very widely used on the web. Bandwidth is not that cheap.

Nah, I have a good sound setup and I don’t want to be watching movies with less dynamic range because some people are using their shrilly built-in TV speakers with their children screaming in the background or $5 earbuds.

If you don’t want to have a proper 5.1 audio setup, it’s not the director’s problem, it’s the media player. Audio compression, center channel boosting, and subtitling are things that media centers have been able to do for decades (e.g. Kodi), it’s just that streaming platforms and TVs don’t always support it because they DGAF. Do look for a “night mode” in your TV settings though, that’s an audio compressor and I have one on my receiver. If you are using headphones, use a media player like Kodi that allows you to boost the center channel (which is dedicated to dialogue).

Stocks = certificate of ownership in a fraction of a company. The basic principle is sound and goes back at least to the Renaissance, it’s everything else around it that sucks and creates a plethora of perverse incentives that benefit the capital owners.

Company stocks are not unique there, it’s the most common example but the principle extends to every commodity. You can buy virtual coal or gold right now if you want and sell later, without actually having coal delivered to your doorstep. This is actually a very important market mechanism when it works right because it allows the market to internalize external forces, reducing risk. European energy providers learned this the hard way when prices shot through the roof in 2022 and they were buying gas at “current prices”, leading to funds drying up unexpectedly sometimes to the point of bankruptcy, rather than buying gas at “future prices”, guaranteeing deliveries that were paid for months in advance. When it works well, speculation is actually an inescapable tool of complex modern economies. Without it you cannot maintain supply chains fit for the modern world, as speculation (when not abused) is the market’s way of accounting and preparing for the expected future.

Even in a communist society, you’d need stocks: the disagreement then becomes whether the state should own (part of) the stocks, or if the workers should own all the stocks (legally equivalent to the means of production).
