<p>Denmark never denied an approval, so it has no meaningful difference.<p>At one point the US had 17 small bases in Greenland. Almost all have been abandoned by the USA on its own initiative.<p>Look at this map:  <a href="https://www.researchgate.net/figure/Former-US-air-bases-in-Greenland-during-WWII-the-air-base-of-our-interest-is-circled_fig1_373652483" rel="nofollow">https://www.researchgate.net/figure/Former-US-air-bases-in-G...</a><p>Today there is only the small Thule/Pituffik base.<p>The US has closed the bases because they make no sense with modern military and satellites.</p>

<p>This is a good live map of how Europe is partitioned into zones and what their prices are.  Right now you can see a large price difference between Sweden and Denmark and also with Norway.<p>Britain is often suffering high prices, likely due to lack of capacity in connections with the mainland EU.<p><a href="https://app.electricitymaps.com/map/zone/DK-DK2/live/fifteen_minutes?signal=electricity-price" rel="nofollow">https://app.electricitymaps.com/map/zone/DK-DK2/live/fifteen...</a></p>

<p>I think this comes from the same problem as notifications on iPhones: if you dismiss them accidentally then it is very difficult to find out what it was.<p>It is missing the equivalent of the "history" in e.g. browsers and YouTube.<p>If a user dismisses an alertbox on desktop, why isn't there an history menu item that  shows the previous 100 alert messages?</p>

<p>I'd really wish I could force ISO format for the date input as the current "platform native" is confusing for some users when the OS use a different language than the web page that is shown.<p>For some multi-country companies it makes sense to have all admin pages in English no matter the underlying OS language.  Imagine sending a screenshot where the OS date format is different from what everybody else expects from an English page.</p>

<p>Los Angeles has mountains/water on all sides so it can't grow in size.<p>It also utilizes the space extremely inefficiently.  Single level single family houses everywhere and the rest is parking space.  The few parks are difficult to access by kids arriving  by foot/bike.<p><i>This is what results in the high rent:  Can't grow supply and don't use existing land efficiently.</i><p>Density: LA = 8,210/sq mi,  Lisbon = 17,040/sq mi, Paris = 10,100/sq mi, Amsterdam = 13,670/sq mi, Copenhagen = 19,195/sq mi. (from wikipedia)<p>Look at Google Street maps: LA is a hellscape of concrete and asfalt.  Lisbon and Amsterdam are much nicer and greener and they stil have higer density.</p>

<p>precision loss in floating point is often exponential.<p>If 64 bit isn't enough, then very quickly 128 is also not enough.<p>If precision is important then you will very often want systems that represent every number as an interval [a, b] meaning that the true value is between those 2 numbers.  This makes you able to detect loss of precision due to e.g. d = a / (b - c) where b-c can result in a number close to zero which makes uncertainty grow.  If you use this formula iteratively then precision is lost completely no matter how many bits there are in your floating point variables.</p>

<p>The KISS version of regulation would be that stores are not allowed to use the word "buy" when you don't get full ownership and must use the word "license" instead.<p>Also it should be marked clearly that the company can rescind the license at any moment without giving any reason why.</p>
