    That's not really accurate. An overwhelming majority of the simplified characters have had their own code points in Unicode ever since 1.0. Some more details here: https://r12a.git…

    I mean, you can call it a "mountain" of greenwashing but to me it looks more like a mole hill. Total Swedish electricity production is typically 160 to 165 TWh per year and total c…

    That may be true in many places, but the Swedish forestry industry is very big, and the district heating plants really do burn mostly forestry byproducts. Of all the biofuel used i…

    For Sweden, the coal plants were exclusively for cogeneration (district heating with electricity as a byproduct) and only used as peaker plants in winter. Some of them still exist …

    The Norwegian Consumer Council's entire yearly budget is about 100M NOK, or about $9.5M USD at the current exchange rate. They most assuredly did not spend >$1M USD on a short vide…

    I mean, for the most part the book is an edited transcription of what he said at the lectures (or, in some cases, what a guest lecturer said). But the lectures weren't scripted, an…

    > The speaker says that Feynman didn't write the Feynman lectures. Wrong. No, she's right, just talking about a different thing. "The Feynman Lectures on Physics" is a physics text…

    Most district heating systems in the Nordics are publicly owned, in part or in full. There are also price controls for the privately owned ones.

    Maybe. I guess it's easier to handle in treated form though. At the point where it gets to the facility it's actually not really sewage anymore, it's just clean water, so after pas…

    Sweden's first commercial nuclear plant[0] was built right next to a newly constructed suburb precisely so that it could be used for district heating too. And also for producing sm…

    Looks like the expansion to 300 MW will have Stockholm beat soon if it hasn't already happened! Or is that in a different plant? Wasn't entirely clear to me, but great progress non…

    Those are some big heatpumps, but in terms of installed capacity at a single location they have yet to beat the Stockholm municipal heating utility's installation at Hammarbyverket…

    Heating with gas is absolutely not a thing in Sweden, I don't think even a single percentage point of homes use that. Firewood is way more common (it's relatively commonplace in th…

    A lot of the Nordic heat pumps are ground source, that is to say you drill a hole a couple of hundred feet down into the bedrock where it's always a bit above freezing and you circ…

    The fuel pump not automatically restarting on power loss may actually have been an intentional safety feature to prevent scenarios like pumping fuel into a fire in or around the ge…

    All of these reports are effectively autogenerated by Big Sleep from fuzzing. Again, Google has been doing this sort of thing for over a decade and has found untold thousands of vu…

    There are dozens if not hundreds of issues just like this one in ffmpeg, except for codecs that are infinitely more common. Google has been running all sorts of fuzzers against ffm…

    In the EU the authorities have recognized the power of the card networks and introduced price controls on interchange fees in 2015, capping them at 0.2% for debit cards and 0.3% fo…

    Generally there are never any transfer fees for private individuals doing domestic transfers. The banks just provide that service for free and eat the cost. Businesses wanting to a…

    Having a cash register and handling cash costs money too, doesn't it? It's just a cost of doing business.

    Credit card fraud is not nearly as common in Europe as it is in the US. Additionally, and specifically in Sweden, the fees that banks charge businesses for handling cash (picking i…

    A cheaper alternative to cards here is app payment via Swish (approximately like Venmo). Goes straight to the vendor's bank account at a flat rate of the equivalent of USD ~$0.15 p…

    We usually use an app for that (Swish, it's kind of like Venmo I guess, developed in collaboration between the six largest banks). We don't really do transaction reversals in the s…

    I'm Swedish and if someone insists on doing a transaction using cash when Swish or card is available, I'd immediately start to wonder if it's for some kind of more or less shady re…
