This washing machine sized box draws 50kW of power. It wouldn't be able to heat up a cold swimming pool very much, but it would be enough to keep a pool that's already hot at a stable temperature.
Usually, when refineries flare something like that it's because what they are burning is not suitable for use, and making it suitable would cost more than the product would sell for.
Often methane as a by-product of oil production is flared, because the amount is small enough that it's not worth setting up processing plants and supply chains for. Other times, the fluid is heavily contaminated by e.g. sulfur compounds, and would be costly to purify. Still other times the production of the fluid is unreliable or intermittent, and cannot sustain a continuous production process.
Although, flare gas recovery systems exist nowadays to make use of these waste gases, commonly for local power production for the refinery itself.
There are unregistered trademarks as well as registered ones. Usually the "TM" symbol is applied to unregistered trademarks, and the ® symbol for registered ones. Both enjoy protection, although it's generally an easier time in court when your trademark is registered.
Whether actively defending your trademark is actually required is a bit of a nuanced topic. Generally, trademarks can be lost through genericide (the mark becomes a generic term for the type of product) or abandonment. Abandonment happens when either the mark owner stops using the mark itself, or takes an action that weakens the mark. The question, then, is whether failing to defend infringing use constitutes a weakening action. Courts differ on this, and there is a large gray area between "we didn't immediately sue a local mom-and-pop shop" and "we allowed a rival company to use the mark erroneously across several states for years without taking action."
You are absolutely correct. Valve's linux push was driven by developments in the windows platform, specifically around the release of windows 8. Microsoft was pushing a windows store similar to Apple's app store, and Valve was unequivocally stating that they were worried Microsoft would basically lock down the platform and only allow software sales through their own store, destroying their steam business. Gabe said it plainly himself (https://www.bbc.com/news/technology-18996377):
> Mr Newell, who worked for Microsoft for 13 years on Windows, said his company had embraced the open-source software Linux as a "hedging strategy" designed to offset some of the damage Windows 8 was likely to do.
> "There's a strong temptation to close the platform," he said, "because they look at what they can accomplish when they limit the competitors' access to the platform, and they say, 'That's really exciting.'"
> This is seen by commentators, external to be a reference to the inclusion of a Windows Store in the Microsoft operating system.
Having an open platform is good for consumers, but Valve is primarily looking out for themselves here. Gabe realized that windows could take Apple's IOS route (i.e. https://blog.codinghorror.com/serving-at-the-pleasure-of-the...) and lock down their OS, and everything he's done since has been an effort to protect his company against that existential threat.
I'm sort of the inverse of this author: I have always liked Python and disliked Ruby. It's true though that python has changed a lot, and it's a mixed bag IMHO. I think every language feature python has added can have a reasonable argument made for its existence, however collectively it kind of makes the language burgeon under the weight of its own complexity. "one way to do it" really hasn't been a hard goal for the language for a while.
I'm really charmed by ML style languages nowadays. I think python has built a lot of kludges to compensate for the fact that functions, assignments, loops, and conditionals are not expressions. You get comprehensions, lambdas, conditional expressions, the walrus operator... most statements have an expression equivalent now.
it seems like, initially, Guido was of the opinion that in most cases you should just write the statement and not try "to cram everything in-line," so to speak. However it can't be denied that there are cases where the in-line version just looks nice. On the other hand now you have a statement and an expression that is slightly different syntactically but equivalent semantically, and you have to learn both. Rust avoids this nicely by just making everything an expression, but you do get some semicolon-related awkwardness as a result.
As far as I know, the science on this is far from settled. There is no consensus and the evidence in favor of a trophic cascade in Yellowstone came predominantly from two studies done by the same team/person. Later studies failed to replicate findings.

Unfortunately you may have to wait some time, at the moment the journey is not be completable because the Paris-Moscow express service (and indeed all train service between Russia and Western Europe) is suspended due to sanctions against Russia.
iDeal is ubiquitous in The Netherlands for individuals sending money to each other, and for online payments. However it does not support NFC payments in physical stores. Dutch banks decided to go with Google/Apple wallet for this. I believe in the longer term Wero https://wero-wallet.eu/ (and potentially the digital euro https://www.ecb.europa.eu/euro/digital_euro/html/index.en.ht...) is supposed to take over this usecase in the EU.
