Dark matter is not just a mathematical construct to explain velocity curves, even though historically that was the first step. Since then, we found compelling evidence of dark matter acting as gravitational lenses. It is a very real phenomenon, as we absolutely know that there is an excess of matter that is dark, i. e. not radiating or absorbing light. Some open questions still exist about dark matter, such as whether it is made up of particles and how they are generated. But the question of whether it is real is settled.

Dark energy is more of a placeholder name at the moment to explain the accelerating expansion of the universe. It is more contested in the scientific community and there is no direct evidence of this energy yet, some cosmologists deny the existence of dark energy at all and claim that is a mathematical flaw in general relativity (the equivalent explanation of dark matter as a flaw in current models called modified Newtonian dynamics or short MOND, is a very fringe theory by now). As such, the question of whether dark energy is real is not settled, it is currently a prediction to explain some observations but lacks further evidence.

Taxes on gas seem to be particularly high in Pennsylvania and Philadelphia. Nevertheless, after searching a bit, there is also a Philly gas station around Philadelphia selling it for... $3.47. To me, this outrage about Freedom Fuel feels either like effective marketing, or its other Petro companies trying to keep out a competitor to justify their profitable "market prices". Even if its something else, it seems effective enough to have Democrats defending the Petroleum industries pricing practice.

Gas in Wisconsin has been fluctuating around $3.40-3.60 the last two weeks, today its $3.49. This is not just Costco and Woodman's, but also some pure gas stations like Citgo. According to the article they must all be loosing money. Is there anything I'm missing here?

The actual cost to OpenAI is likely much less. The number in the article is calculating the API cost that a fully maxed out subscription would incur theoretically. The API token cost, however, is far above the actual computational cost.

To make a fresh install less painful: Most applications save all user data in your home folder under .config and .local. Some others make their own .folders, which you can see pressing ctrl+h (for hidden) in your file explorer. You might save these and carry them over whenever you wipe your OS. If you save a list of installed packages from your package manager as well, you can get up and running in just a few minutes on a fresh install.

They don't sell them on their own website anymore. You can buy them only on stacksocial. Site looks a bit shady, but it is actually legit and in partnership with koofr. VAT is excluded from their payment screen, so do take that in mind. Later on you can upgrade your account to 2.5TB for an additional 300€ directly on koofrs website.

To protect your privacy, always encrypt your sensitive uploads with rclone or something similar. The backend is almost irrelevant then. Still, there are often some unforeseen bugs or artifical limits set by the providers. The only way to find out if a service really works for you is stresstesting it with your workflow. Most services offer a few GB for free to do that. Some examples of what may go wrong: A few years ago I've run into some problems with Proton and Zotero and quickly decided against it. My KeePass app stopped syncing with a seadrive server at some point. One nextcloud provider didn't like my seedvault backups and always dropped them halfway through.

I've been mostly using Koofr because it's european and there is a lifetime 1TB purchase available on stacksocial. Some view lifetime subscriptions as a controversial business model, but I like it better than a monthly subscription. Koofr also encourages rclone usage and I haven't run into any problems yet, but, as stated above, your mileage may vary.
