<p>The most offensive part to me is that it tries to excuse obscene wealth as simply (shrug) a pesky, I mean "magic", byproduct of math.<p>Regardless, can we talk about the danger to society of having these resulting billionaires and how we ought to address that? I think that is in fact what "the politician" mentioned in the article was trying to address.<p>(The <i>new</i> American Dream appears to be: be one of the 30 people every 21 years that finds themselves the head of a startup that succeeds.)</p>

<p>"So you can imagine how astonished I was last month when an American politician said that it was impossible to earn a billion dollars… What she meant was that it's impossible to get that rich without doing something bad — without cheating in some way."<p>Not <i>exactly</i> the way I interpreted it (emphasis on <i>earn</i>). Right or wrong, I think the vast majority of us think that "deserved money" is money <i>earned</i> from "work".<p>A simple example would be the billionaire Walton children: their fortunes inherited. Most people would argue that they did not really <i>earn</i> those billions of dollars.<p>On an admittedly slippery slope, for many, investing and other means where the <i>money makes money</i> is also not regarded as work (and therefore is not earned money).<p>To wave around the idea of "the American Dream", I suspect that many American's disapprove of any means of obtaining wealth that the average Joe or Jane are not privy to. This idea that you have to be <i>born</i> into money or <i>have money</i> to make money—we are (perhaps naturally) repugnant to.</p>

<p>Apple engineers partnered with Sony, Canon, Nokia, Adobe, Microsoft to try and hammer out a specification that addresses when different metadata flavors overlap (EXIF, IPTC, XMP) [1]. It was not comprehensive (to be sure) but covered the most common properties.<p>As was more or less discussed in the post, EXIF concerns itself more or less with hardware and camera attributes and can be considered authoritative for that domain.<p>IPTC was added by photojournalism to cover more artistic metadata like a caption, author (photographer), keywords, etc.<p>Like the one XKCD strip, XMP seems to have come along to try and create a 3rd standard to replace the first two…<p>[1] <a href="https://en.wikipedia.org/wiki/Metadata_Working_Group" rel="nofollow">https://en.wikipedia.org/wiki/Metadata_Working_Group</a></p>

<p>Finished my little hobbyist, analog computer project. It consists of PCB modules that you plug into a breadboard and wire inputs and outputs together in order to program it.<p>The most novel thing about it (besides the breadboard being a central component) is probably eschewing panel meters or oscilloscopes and using an ESP32 and LCD display (and a bit of <i>digital</i> code) to display the various voltages/values that you connect up to it.<p>Kind of an open, learning platform to satisfy my curiosity about what analog computing was all about. It succeeded.<p>This month I am putting together a couple of dozen kits, preparing some YouTube videos, and generally trying to roll it out by July. (Still more modules could be built for it though—a log/anti-log module would be nice, sine/cosine is not out of the question… It's open, so perhaps someone else will create these or other modules. Or maybe I'll come back to it this Winter and add a few of those.)<p>Just a little example here, wired up (programmed) for Lotka-Volterra simulation (only a few dozen wires of code!). It's using a kind of strip-chart mode programmed on the ESP32 to display the voltage inputs representing predator and prey populations:<p><a href="https://youtu.be/CjvM9tRrSNU" rel="nofollow">https://youtu.be/CjvM9tRrSNU</a></p>

<p>Me as well. But there are obvious hints that the roots of religion are involved—the explorers go from being very fact driven to eventually wandering more on faith than anything else. There is also a kind of recursion within the story that suggests larger ideas as well…<p>But, yeah, we might just have to ruminate on how a work of fiction like this makes us <i>feel</i>.<p>After seeing a lot of indie films, I've come to find peace with that idea: that not <i>everything</i> in fiction has to be knowable, have a series of events that build to some succinct conclusion.<p>(And I probably encountered this first even when in elementary school when a teacher finished reading a book and asked us, "What do you think happened to the boy after the story ends?" Initially frustrating to me, I came to accept that perhaps the author is allowing my own imagination to participate as well.)<p>Sometimes, you wake up from a semi-lucid dream with a feeling unlike any you have had before. An attempt to describe it with words or visually will, if you are lucky, come close to approximating it. Almost surely though the fiction that results will be inscrutable if held to standards of logic or narrative. And that's just the way some things are within the human mind.</p>
