Since this paper is a preprint published on arXiv, and seems that it hasn't been peer reviewed. How do we know that it isn't a LLM creation in its entirety? How do we know that in general of any paper published in the LLM era? Attentive peer review, that's our only defense. In this age of paper mills and "minimum publishable units", pay-to-pay publishers, all bets are off. The publishing game seems to be irreparably damaged. It is clear that the sites that compile these metrics can do much more to improve the quality of their analyses. For reference, my publishing birth-year is 1989, and papers listing me as an author have over 8,000 citations. I've chaired faculty search committees. Anyone who relies solely on simple metrics in evaluating scholarly productivity is a fool. Metrics provide the first whiff of productivity. They are not the meal.

This was done over 20 years ago. Someone entered Lotus 1-2-3 clone entry in the obfuscated C contest in the '90's. It worked. I've got the code around here somewhere.

Here's an analysis. Enjoy. https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fyoutu.be%2FPRwV9rn2794

The geological record shows strong evidence of at least three mass extinction events in the past 450 m.a.. How many will occur in the next billion, before this supposed great "oxygen crisis" kills what might be alive then? Pretty sure it won't be homo sapiens. Academics making bold speculative claims. Nothing to see here.

In the US, the Federal Aviation Administration has recognized that the loss of GPS signal is an eventuality. The contingency is met by maintenance of a "Minimum Operational Network" of ground-based VHF navigation stations and instrument landing systems at many airports. Most aircraft GPS units are compatible with this VHF ground-based navigation system as well. If GPS goes, we will lose a lot of functionality, but we can revert to what was done before GPS came along. We'll still be flying, just along Victor airways.

I've been flying small aircraft for almost 40 years, and recently I've seen a rash of runway renumbering. Runway numbers are assigned according to the magnetic heading of the runway (degrees), rounded to the nearest 10 degrees and divided by 10. So, a runway on a heading of 217 degrees magnetic would be called runway 22. As the Earth's north pole moves, it changes magnetic headings too. Runway numbers at airports near me have changed recently due to the magnetic field shift associated with the eastward movement of the north magnetic pole. For instance, runway 36 recently became runway 01 at Fayette, AL, where I stop to buy cheap aviation fuel. This is important to know, particularly for those flying instrument approaches, where the name of the approach is tied to the runway number. It won't affect GPS navigation, because GPS works in geographic (latitude/longitude) coordinates.

DoD finally had enough of poorly reinvented Unix. Hell, even Microsoft is starting to get it!

The cited article (Chi et al. 2019) says nothing about a subsurface conductive layer or speculation about groundwater. While there are plenty of studies the show evidence for groundwater on Mars, this isn't one of them. The article does say that the magnetic field pulsations are thought to be due to changes in the Martian magnetotail. This post suggests relevance in unbaked, preliminary, non peer-reviewed science. This is part of what is wrong with science reporting in this age of "fake news". I'm surprised this got moved to the front page.

Google "barchan dune"...

The study must have required that the study participants be actively listening. There is a difference between that and passively listening. I have done a lot of coding to music. I find that when not employing the Balmer maximum method, listening to appropriately harsh metal or alternative rock helps me stay in the zone.

As a researcher who has made and published "surprising" discovery of a new class of solution to a longstanding problem, my surprise came mostly from knowing that some really smart people have worked on my problem for decades, and they did not find it. I think that understanding of numerical methods led me to approach the problem from a standpoint that they would/could not. Maybe not so surprising then, but invigorating to know that for a time, you are the only person on Earth that knows a certain thing.

So, is it like a futures contract, as in if I want to claim my barrel of oil, I just have to go to Venezuela and get it? Sounds like fun!

Ok, so after reading this my mind swooned to "I want one!" Who wouldn't want such an elegant machine that runs everything natively!?! Then, I remembered why I use Toughbooks- I HATE KEYPADS. Yes, they can be disabled, but then you need an alternate pointing device, which means you need a surface, which tray tables aren't good at. My Aura is so strong that when I move near a touchpad, it causes cursor movement without touching it. The trackpoint is AWESOME. The Lenovo X220 i7 version can be had on eBay for less than $300 too, so they are a commodity item, with 1 USB 3.0 port. I run linux natively with Windoze in Vbox. Luv the X220, light and powerful. Small enought that when you use it on a tray table you don't have to worry about it being schmalled by the schmuck in front of you leaning his/her seat back.

It seems that the barges could easily accommodate a fire suppression system. A matrix of foam shooting nozzles would do it. The system could be autonomous with heat sensors, or just "fire all upon landing". Just an idea.
