It would be great to register this in downdetector to make sure it is up.

You mean "Losely", right...

This is a great article! Funny about Yugiri (39), because your version is a mirror image to Eawase (17), and the traditional Japanese Yugiri breaks that symmetry.

Every Genji-mon that is not self-symmetrical should have a mirror image, which I was able to quickly verify in the Genji-mon table you displayed.

Minori (40) is the only non symmetrical Genji-mon that breaks the rule, because it's the only one whose mirror image is also isomorphic to itself.

I can only imagine that there was something deliberate about the symmetry breaking for Yugiri, given the almost fanatical attention to detail in Japanese arts in general, and the equally strong penchant for deliberate imperfection in traditions like Kintsugi.

Brilliant synthesis:

Globally humans have transitioned almost overnight from information/knowledge scarcity to information flood. Once we had plenty of time to forage information to construct narratives and share them and agree/disagree on them before the next influx. Now we are literally waterboarded with information that has no context, minimal sharing and no real conversation attached. We are left with whatever individual narrative our pattern matching can construct, and it's usually inadequate. Narrative is definitely a superpower of the group not the individual.

We may need to wait a generation until people who have grown up in this world and can filter feed on the information can create/disseminate narrative adapted to the new rate of information flow and yet somehow true to reality.

Loved the article! There are so many great details such as the standardization of UTC happening after UNIX time invented, UNIX itself being born before the epoch, and all the great insight into the morass of 64 bit time across modern OSes.

Putting on my pedantic hat though, I see that East and West were switched in the discussion of Japan's unique 50/60Hz AC frequency split, and I can't get my mind off it. Hope you can make the edit.

I was a teenager, desperately looking for the cheapest possible system (because I couldn't afford any of them). And I would longingly read all the ads hoping a miracle wold happen. Later on I learned that one of those companies was named after the college dorm where the computer was conceived. So cool.

Null island is like the opposite of the Bermuda triangle. In fact, maybe they form a portal...

Also, very relevant to discussions of whether we live in a simulated universe!

The whole discussion of whether we live in a Matrix-like simulation falls into this category as well. There are so many layers of oversimplification at play in most peoples' conceptualization of a simulated universe that it is hard to even begin to have a conversation about it.

Companies fill ecological niches. When new technologies emerge there is room for a new apex species/(company), and a few smaller wannabes. There just isn't unlimited room for large companies to emerge, and that is the principal reason why there aren't more googles and facebooks around. In the end it has very little to do with VCs and entrepreneurs, except for the ones who happen to be in the right place at the right time to take an as yet non obvious idea and turn it into something huge.

Here is the reference for the most recent work (2019) of note in this domain. Ulf Adams extended his 2018 Ryū algorithm to implement Ryū printf which is 4x faster than the best other implementation tested on Linux, Mac and Windows. https://dl.acm.org/doi/pdf/10.1145/3360595

The reason Instagram's founders are no longer there is because they could not stomach being forced by facebook to publicly make these kinds of statements.

At a meta level, Category Theory requires some comfort with abstraction, which really only comes with a mathematical education. So while it may stand apart from much math, it relies on your strong mathematical foundations.

Rob Pike's rules of programming simplified :

- Start with stupid code built on smart data (after Fred Brooks)

- When in doubt use brute force (Ken Thompson)

- Premature optimization is the root of all evil (Tony Hoare)

I would recommend this method for documenting all functions, processes, APIs. It can be seen as making explicit what intended inputs, and outputs are, and adding layers to describe input validation to eliminate (buggy behaviors), and testing/fuzzing to prevent introduction of risks, and enabling exception code to mitigate unavoidable error conditions upon process completion. The bowtie method really encapsulates software behavior quite well.

This article gives the more detailed explanation of the chart's data. https://en.wikipedia.org/wiki/Nucleosynthesis

BTW, image search of nucleosynthesis gives about 10 different versions of this infographic, with fairly significant variation.

My 2 cents is that I can ask just about any question I can think of and absorb and internalize an amazing answer in 5 minutes of reading. Many of those same questions can be automatically asked and answered too. The web and search engines are realizing the promise far better than anything else.

You can actually use the google ngrams data set to determine that the long s was eliminated from print over a 25 year period roughly from 1795 to 1820.

if there aren't any 0 0 coordinate airports in the data set, maybe there are some strings that are not parsed as numbers and thus coerced to 0, a space or a non printing character (like a carriage return) can make something that looks like a number, not parse properly.

I'm looking forward to every update that pops up. Really inspiring!

I made a small error in my explanation for the date line: I meant to say "voronoi border with the cells just to the west" (instead of east)

By the way if you have a list of the 0 0 coordinate airports, I can do a best effort search for their correct location. Let me know,

Gorgeous! I did notice that the international date line is marked as a voronoi border from north to south pole. If you can do some modulo math trickery you should be able to fix this. You can find all of the cells/airports forming the border to the east of the date line and add fake airports to your data set with longitude 360 larger than the original cells. These will be used to create the correct voronoi border with the cells just to the east. Everything else will stay the same.

Thanks to the transparency of the globe I noticed this when @MereInterest pointed out the 0 0 coordinates of several airports.

By the way if you can find a way to add the airport call letters to the cell when clicked that would be amazing.

Is there any way to determine exactly when this document was written? I've read accounts that indicate that it took some time (weeks, months, years?) before the metaphor of mushroom shaped cloud entered into the vocabulary used by witnesses of atomic weapons. Fermi's account would disprove that assertion if it were written immediately after the test at Trinity.

I was in the Boston suburbs (Newton) for 6 years, during which my dad went to MIT for a graduate degree, and I myself went to Stanford for a PhD in CS. When I was an undergrad I sat in on a couple classes at Harvard. The caliber of student you will meet is roughly equal.

I think your undergraduate years are a great time to explore, so I would highly recommend leaving your comfort zone, whatever that might be. Moving away from the Bay Area is a great way to spread your wings. Taking several courses in a field that is different/challenging and potentially a minor field of study is another way to do that.

Use that experience as a lens to focus yourself on a graduate degree/entrepreneurial career. If you leave the Bay Area, and you want to do startups, definitely come back to Stanford for a master's degree, or even a business degree, and then do it. There is really no better place in the world for entrepreneurship.

Don't get fooled into thinking that your undergrad years have to be hyper focused in order to succeed. As a matter of fact, it's the best time to broaden your interests, and get to know understand the people who have the same interests as you. The best entrepreneurs build amazing social skills to complement whatever talents they have. They almost never start companies alone, and they have usually spent years working with friends/team. The most novel startups also usually combine ideas from multiple fields. Your undergraduate years are a great time to put those pieces together.
