The supporting materials for EconTalk (from econlib) are also fantastic -- you can go deep into the topic with curated resources for a lot of stuff.

I tell people that if I had a year I'd systematically walk through the EconTalk back catalogue and emerge with a better education than people who get 4 year degrees in the topic.
I actually learned a lot of interesting factoids from a debunking movie, https://www.ancientaliensdebunked.com/

So yes, I would definitely watch "rebuttle" documentaries! Are there any others out there?

I was pretty mad at the guy who kept asking basic linear algebra questions in a course that already had linalg as a pre-req.

Yes, I know you don't know that, and yes, you're going to be confused if you don't remember how to diagonalize, but this is your 4th linalg question today, can you please review your linalg notes before next class? It's not just you but a whole class that's held up here.
I don't have good answers to your questions. But I do have this advice: get a good lawyer and a good accountant. Don't try to do taxes or legal paperwork on your own. It's never worth it and the cost of doing it wrong is so high.

AFAIK Sweden says no to both.

The Swedish Medical Products Agency (Läkemedelsverket) said on April 2nd that chloroquine/hydroxychloroquine should be used for the Covid-19 indication within clinical studies only, otherwise only for the approved indications (arthritis, lupus and similar). This is because the available data does not offer robust conclusions on efficacy and safety. [1]

This is in line with EMA recommendations, which defer use within emergency programs to national authorities. [2] And in Sweden's case they say "no".

What I understood from the article: it's not the engine that rotates.

Instead, the fuel mixture ignites in one spot, and the explosion spreads at Mach 5 around the engine but once it reaches the end of the combustible fuel, more is injected behind it so the explosion can just keep traveling around in circles.

Judging by the article they managed to get that working, and also came up with a better way to take videos of this happening (high speed camera, tracer chemicals in the hydrogen, better signal strength).
according to the article, it’s the _explosion_ that rotates around the engine, not the engine

« rotating detonation rocket engine»

« The rotating detonations are continuous, Mach 5 explosions that rotate around the inside of a rocket engine »

maybe like a wankel engine without the rotor?
Why is it a solid choice? To me it seems mild hybrids are primarily means for grabbing government subsidies for electric car development without having to do much technical development, but I'm not very informed about cars.

We run our company through Notion. Part of using it is establishing your own best practices within the company. Since Notion is flexible, it provides you the opportunity to be rigid and make the decisions on database design that is right for your team.

Notifications in Notion are very poor and that is a valid criticism mentioned in the article. I imagine it will only improve over time and with the coming public API we should start seeing third-party tools supplementing Notion for specific use cases.
I’ve found some companies use the rating systems to tailor interviews to your strengths by providing descriptions at each level (e.g. “10 means you wrote the book about it”). It’s not always useless.
Thanks, I feel enlightened. You could write press releases :)
From the amount of late 90s early 00s indie rap of my teens I've found there that has never been available on Spotify, Apple Music may have the bigger catalog.
I am a huge Notion supporter - it's our organizaation's brain and one of our most important tools.

However, having used the tool for more than a year at a 20 person org, one of the biggest pain points I have seen is people not knowing where to place new pages. There is "Notion anxiety" about not wanting to mess up the board.

One thing we've done to address this is by adding two common tables, the Documentation table and the Meetings table. Anytime anyone wants to create a new doc, they can simply add it to the documentation table and then tag it to their team, and we have a full list of all of the docs everyone has written. From there, if a certain piece of documentation needs to be somewhat else, it can be pulled out and moved there. Additionally, each team member has a default "project board table" and if you say need to create a quick to do list, you should just add it to your personal board. Having these "default tables" rather than a special table for each specific project may really help your team.

Notion requires intentional planning, and you need to be opinionated about the architecture. If you just keep adding things on haphazardly, it's going to turn into a mess.

Finally, I do agree with OP that notifications could signicantly be improved. If anyone from Notion is reading this, please think of notifications like emails. At the moment, notifications are only in the state of read/unread, and as soon as I open my notifications, they clear. Instead, I want my notifications to be a mini-inbox, where I can view notifications, respond to notifications, archive completed notifications, and filter notifications into channels (the same way I can filter emails). Notifications are a to do list, and should be thought of as such. Having this set up would address OPs concern about being able to filter notifications at the email level by setting the filtering logic in the app.
>at least one statement in the thesis about Gentoo is no longer true (Gentoo prefix allows regular users to install and manage packages using portage on a variety of systems [0]).

I assume you're referring to the following sentence, but that's not what it's talking about.

>As claimed in the introduction, deployment systems tend to have monolithic trust models. Typical Unix package management systems such as RPM [62], Debian APT, or Gentoo Linux [77] allow installation of software by the administrator only; software installed by individual users is not managed by those tools

This is talking about a single instance of the package manager; for any given instance of the package manager (where an "instance" is defined by various things like the list of installed packages, package data, various package management databases, etc.), only the owner of that instance is allowed to install new packages. For a system-wide package manager, only root is (safely) allowed to install new packages.

Even at the time, RPM and dpkg, and presumably portage, had the ability to create non-system-wide instances of the package manager, like Gentoo Prefix does; but even for such instances of the package manager, it's only safe for the owner to install new packages. (You wouldn't want random other users installing packages in your home directory!) Such instances don't share anything with the system-wide instance - it's essentially like creating a chroot or container.

The reason this is being pointed out in the thesis is that Nix does not have this limitation; any user can safely install arbitrary packages into the system package manager, which are visible to the system, share package data, etc.

I'm taking pains to be clear about this because, IMO, this is one of the places where Nix has the clearest advantage over traditional package managers.

> Unless of course you want to assert that we should care more about some deaths than others. But that is a political statement, not an epidemiological one.

That said, I'd love to see a model that does assume the population cares more about some deaths (notably their own, and those of their close friends and family) than others.

The starting point for epidemiology and public health is that all life is sacred and worth the same, and we should protect life at all costs. There's pretty ample evidence that much of the general public doesn't actually believe this, though they'll publicly profess to because there's immense social stigma against wishing other people dead. But note how many people make comments in the vein of "It doesn't affect young people", "This is only a big-city disease", "It only affects Asian people", "Yes, yes I hope Trump supporters do drink some bleach", "I hope he dies of coronavirus", or "Good, Darwinism in action." The mods of r/coronavirus had to make a blanket policy against wishing people dead, and regularly lock threads because of it.

Public health interventions only work if people follow them, which implies that a.) the citizenry needs to trust public health experts and b.) their goals need to be aligned enough that citizens think it's in their best interests to comply. There's a very common failure mode for other system-design efforts in assuming that the stated goals of the project are the actual goals. I'd love to see a model that assumes people are self-interested actors that respond to fear and greed, rather than one that takes as a given that they'll act for the common good.
It's unfortunate "real-time" is getting so heavily overloaded. It used to mean "guaranteed bounded latency".

"Real-time" is now being used for streaming APIs to mean "small latency on average, but no guarantees".
Blank provides a nice framework for thinking through a business idea but there are companies still selling software for dialup modems and your grocery store (in-spite of terrible fundamentals) is still in business.
I've always readily admitted when I don't know something. Might be that I was raised in Arkansas, where ignorance is a little more acceptable.

It's usually a great benefit for me, for the same reasons the article describes. However the problem I've found is that--as an engineer--if you don't profess complete knowledge, there's a limit to how effective you can be in leadership. Engineers don't take you seriously, if you act as though you have any doubt in yourself. It's a wall I keep hitting and I've about decided I need to start feigning full-bore 10x brogrammer ego just to herd some cats.

> For years the world will be harsh for the ‘bottom 50%’ but we can hope for some sort of transformation.

All I want for Christmas [in 2020] is for that "bottom 50%" to not pick up pitchforks. Never forget serious tail risks. Will we still be using the same system of currency 5 years from now? Will entire stock markets become nationalized? Will we get true dictators in some "medium quality" countries or perhaps even in some "high quality" countries? Will China survive the massive lack of demand without political or military turmoil?
What about the study clearly showing no benefit, but a higher death rate in the group that DID use hydroxychloroquine?

See: https://www.cnn.com/2020/04/21/health/hydroxychloroquine-vet...

Seems to me the Remesedevir is the better option, and may be the first silver lining.

I've told my wife, if I can't make the choice do not let them put me on that chloroquine no matter what. Also no ventilation without sedation/paralytics (in case of shortage, I'd rather die than be vented and wide awake).
I’ve gotten by without a good lawyer so far. God they’re expensive.

Great accountants OTOH are cheap, and yes they are critical.

Endocannabinoids are produced by the body when Omega-3 is consumed.

Too much Omega-6 seems to limit the body's ability to utilize Omega-3.

Reducing inflammation (which is good for hyper-inflammation, which pollution can cause or worsen) is one function of the endocannabinoid system (ECS).

A search for `Omega-3 endonannabinoids` on GScholar:
https://scholar.google.com/scholar?hl=en&as_sdt=0%2C43&q=ome...

The Omega-3 wikipedia page lists a number of foods sorted by Omega-3 content in descending order:
https://en.wikipedia.org/wiki/Omega-3_fatty_acid#Dietary_sou...

The top two sources (flax and hemp) are plant based and thus have ALA but not the DHA or EPA that some animal sources have.

Fish don't produce Omega-3: they eat algae and then the PUFAs (polyunsaturated fatty acids) are stored in fat.

Fish and cheap fish oil may have other contaminants due to pollution in our lakes, streams, and oceans.

It's important to eat a balanced diet. Eating anti-inflammatory (and anti-oxidant) foods is one way to regulate hyperinflammation.

Any form of combustion (burning carbon matter) produces carbon monoxide. CO is terrible for most living things in part because the unbound oxygen binds to whatever it finds (oxidization).

This is how the economics of all resource extraction works, not just oil. As prices rise and fall the economic viability of extracting a particular resource pocket changes. It's all in equilibrium and prices typically don't move as much as oil has in the last three months because market forces and people generally don't want to shoot themselves in the foot. The long term economics of Russia and KSA crashing the price so they get a monopoly doesn't make sense, doing so minimizes their profit if done over the long term since capital costs per barrel are fixed. Resource investments are multi-decade, the overall effect of this is going to be a blip in the grand scheme of things rather than an end to the industry.

Lunch during work is a great chance to add some joy to the middle of your day. You spend so much time at work, why not leaven it with something delightful?

Perhaps a side-note, but my most of my experience is the private sector. While the government jobs I've experienced were mostly 'the same' in all the bad ways, at least the pressure seemed a bit lower.

I just wanted to point that out, because I find it extremely frustrating to discuss these matters with various friends who are all in agreement, but then somehow believe this is just a government thing, and as a result seem to be drinking more and more of the 'corporations and the free market optimize this shit away and socialism is bad' kool-aid. Which strikes me as both a simplistic and ineffective conclusion to draw, if we're thinking about better ways to do things.

Oversimplifying, but in my experience the private sector, at scale, is often just as inefficient and bullshitty and mind-numbing and depressing as a government entity, just with less job protection, higher pressure, and perhaps often less of a meaningful societal value, however inefficiently achieved.

And perhaps worst of all, you get managers/bosses who are not just content to do an okay job at their current position, but actively employ a ruthlessness and ambition that makes their stupidity all the more problematic.
Here is a video from the Technical University of Berlin where the transition from ignition to the continuous circular detonation was also filmed among other things.

Edit: upon reading more, now I'm not sure if the NYT already has the names and addresses and is just seeking the metadata or if they don't need that data to do their analysis. Your guess might have been right, the ruling is unclear.

I don't know if Schmidt can solve most of the Pentagon's problems, but honestly - I'd really rather those problems never be solved.

Also, Schmidt could solve a lot of problems by stopping the censorship of non-mainstream content on Google Search, YouTube and possibly elsewhere.

Finally, he could solve a bunch of problems by _stopping_ Google's collaboration with the US government and the NSA.

Uncontrolled detonation or pre-ignition is a problem in ICE not because it creates less force, but rather because it creates more force and at the wrong time. If engines could be made strong enough to remain reliable while operating on detonation, and the pulses timed right, I imagine you would get more energy out of a given volume of fuel. This whole problem is avoided in a rocket combustion chamber without all the rotating parts
Depends. For obscure behavior features, ok, for 'language features' I'm probably still going to pass. Because in this example case that would come down do
