I have wondered if heat and photons impart a partial charge on atoms and molecules which causes several phenomena. Faster Brownian motion due to the increased repelling action of stronger charges which cause pressure/volume changes in gasses.

Also are these charges responsible for some weather effects such as the jet stream. In a tornado is the negative charges on the dry side of the dry line interacting with the moist air on the wet side really just a local intense acceleration of the dry air trying to "get to" the oppositely charged moist air?

Are the rotation of low and high pressure systems basically due to the same condition? Is lightning also just basically a flood situation of the charges?

> In reviewing 6212 COVID-19 patient records, the doctors noticed that many survivors had been suffering from chronic heartburn and were on famotidine rather than more-expensive omeprazole (Prilosec), the medicine of choice both in the United States and among wealthier Chinese. Hospitalized COVID-19 patients on famotidine appeared to be dying at a rate of about 14% compared with 27% for those not on the drug

I guess one of "upsides" of covid affecting so many people around the world is that eventually you start to see a pattern of what types of people are not as affected. Then you can narrow in on what makes those people different, and see whether it's just random chance, something intrinsic to them, or something about their medications/environment.
Well I guess that’s true from a North American perspective. I’ve lived in several countries, and from my perspective, in Asia and much of Europe, that structure seems like it would be considered a passable family home in an urban area. Most urban folks have a different relationship with space — smaller spaces are ok if one is close to transit and city amenities.

I volunteered yesterday after seeing this article. To be clear, this is a very early expression of interest and there is no specific human challenge trial which is ready to begin at this time. Consequently, the exact trial implementation details are to be determined.

That said, I would be shocked if any such trial didn't involve the isolation of subjects in provided accommodations for the full duration of the study. It would be necessary on ethical grounds for the purpose of community safety. Obviously, that doesn't mean you should volunteer (it is still a risk to your health and extended isolation from your family would suck), but they aren't just going to infect you and then send you home to come back in a few weeks.

In his video he even called viewpoint an "editor" as opposed to a "visual programming language." It's clearly not Turing complete and I would say outside the topic of visual programming languages.

From what i understand, the original context of "security through obscurity=bad" is that its really hard to keep secrets, and its hard to design secure systems, so peer review is really helpful. Thus if the security of your system relies on it being secret, you are probably in a bad place because its hard to keep something so big secret, its hard to redesign the system if it leaks, you probably had less people look at it in order to keep it secret. This is in contrast to just having a password or key secret. You can easily change a password if it gets leaked. You can keep a small password secret much easier than the design of the whole system, etc.

More generally, security is like any other field. You have to evaluate arguments based on the logic and evidence given. The main difference is that with crypto, it is much easier to shoot yourself in the foot and have catastrophic failure, since you have to be perfect and the attackers just have to be right once to totally own you. Thus the industry has standardized on a few solutions that have been checked really really well.

More generally, if you are interested, i would say read the actual papers. The papers on bcrypt, argon2 etc explain what problems they are trying to solve, usually by contrasting with previous solutions that have failed in some fashion. That doesn't mean reading the paper will explain everything or make you an expert or qualify you to roll your own crypto. Nor should you believe just because a paper author says something is a good idea that it actually is. It will however explain why slow hash function like bcrypt/argon2/scrypt were created and are better choices than the previous solutions in the domain like md5.

If you're looking for a fully featured framework, Angular is a joy to work with. React is great too, but the configuration overhead is enormous due to the fact that it's mainly a view library. I realize you are pining for the days when you just pasted a CDN link in your index.html, but while those use cases still exist, for the most part users are demanding more native-like web experiences, which requires a bit more complexity.

One of the main strengths (and according to some, weakness) of Angular is that it has everything you might need to create a full featured SPA out of the box, and it's all tightly orchestrated by the Angular CLI. Creating a component or a service is a simple command, and many third party packages leverage the CLI (Angular Schematics) to install and configure themselves in your codebase. Core packages--such as such as forms, router, angular material--are all high quality (by Google), updated together, and work cohesively with each other. That means updating even major versions of Angular is an easy `ng update` command. For me, the minimal configuration overhead is a BFD, as I plain hate that stuff.

The fact that Typescript has been a first class citizen of Angular from its outset makes development pretty enjoyable. I'm so used to exploring APIs using intellisense, leveraging types to figure out what data types can be passed in functions, relying heavily on auto-complete/auto-import to pick up my pieces and finish typing a word for me and importing the corresponding library while I keep going.

Granted, there is a significant learning curve. But once you get over the initial learning curve, you become incredibly productive. Arguably, the learning curve in other frameworks is worse, given that you have to research what libraries to use (e.g., which forms library, with its own set of conventions), configure it, and make sure it plays nice with the other patchwork of libraries.
I agree with this. The idea is to not worry about things you are certain you cannot control.
The first question one should ask is whether one can reasonably expect to make back the energy embodied in the generator. For example, strapping a generator to a stationary bicycle is unlikely to reach this point. Small scale wind turbines have a similar problem [1].

I really doubt that generators in individual houses drain pipes would be viable.

I used to use more "Promises" but now I mostly code with plain callbacks if possible. It is just simpler, less thinking needed. I spend that thinking-budget on other things.

One thing that is tricky with async is that nobody tells you if the async function never does what it should. I wish they would add some more built-in support for that in the next JS version.

Promises hold promise (pun intended) but they are a bit too complicated for my brain.

Oh, it looks like we have ourselves a classic "idea guy"! I've met a whole lot of people like you before. It must be hard getting a job in such a crowded field, especially at a time like this.

So that's a hard no, you've never heard of Scott Kim or Donald Knuth or Xerox PARC, right?

I can see you have excellent soft "people skills", and it must be a delight to work with you. Good luck talking somebody else into implementing your ideas for you, but don't let anybody else know what they are, and keep them top secret, and never discuss them with anyone who's done similar work, and make sure everyone you discuss them with signs NDAs with No Complete clauses (and make sure you're in a state where they're enforceable) and Reach-Around Clauses (in case they fuck you up the ass), because your ideas are so easy to implement once you know them, that somebody might steal them from you before you get around to conning somebody else into implementing them for you for free, if you leak any details of all those original ideas of yours that are all yours and nobody else's and they belong to you and are yours. ahem ahem cough

Maybe you can shed some light on this: I recently took my older (7 years) MacBook Air in to Apple to get a new battery. They charged me $129. It’s a great laptop, was happy to do it.

I'd assume it's the speed advantage, but the only problem I can think of that would require that type of exponential speed is cracking hashing algorithms which just seems destructive and counterproductive, like building a digital nuclear bomb - and from my very limited understanding that's a long ways off from being achieved.

I assume there's probably many more complex computational problems outside of my domain that QC can help with. Does anybody know of any?

If the new idea is bad, the sacrifice is in the experimental group and the control group are the lucky ones that got the best treatment.

Note that in this cases where there is a "standard" procedure the control group receives the "standard" procedure. They are not left alone to die.
[Sorry I have misinterpreted the subject, I thought it could be some phenomenon still not well understood by science.]

Placebo. There are biological bases of it (I don't believe in soul). Find these bases, study them, make a model of them. Then use proxy variables to measure it instead of trying to eliminate it statistically. Predict it in studies to avoid the need of placebo groups (and possibly of double blind methodology). Also, after it is completely measurable and its mechanisms are understood, if (very hypothetical) it has a really substantial effect, just use it to help treat patients.

Was watching a news show about how some beaches in LA are open, but the neighboring ones are still closed. Reported said people were asking for consistency in the enforcement of policies.

Which seemed beside the point. Whether a city seems beaches to be safe to open isn’t necessarily correlated with whether opening them is safe. People can demand opening the economy, opening businesses, opening public spaces. When that’s safe, it’ll be safe. Before then it won’t be.

We should be demanding proper, expedient, optimizing responses to the pandemic, not just a declaration that it’s time to open these things. If that’s how we move, we’ll be wearing masks and social distancing and half filling restaurants for a longer duration, while the pandemic lingers on.

This doesn't really solve GP's problem, as the Nothing type is generally still equal to itself. Certainly useful for general purpose programming languages, though.
JavaScript syntax for generators is clunky no doubt. But they let you do some things more naturally than anything else in JavaScript. They keep track of state "implicitly" you don't have to do an assignment to 'save a state", you just yield and your state is remembered.

I found generators useful for implementing my home-brew parsers. Parsers must try out all possible combinations of possible syntactic elements before they can say that parse failed. Generators are a good tool for that

There is nothing preventing you from charging a fee for Open Source or even for Free Software. You only need to distribute source code to users of your software. That means it does not need to be publicly available on a site like Github. You need to remember that users who receive the software and source code are still allowed to distribute your software for a fee or even free. This method of selling software is not common at all though, so I can't really name any successful projects doing it.

> So why can't this software be called open source, when the source is... open?

The reason you can't call software like that as Open Source is because Open Source has a clear definition as defined by the Open Source Initiative[1]. Free Software has a definition as well[2]. The Open Source definition is a more expanded and detailed version of the Free Software's Four Freedoms. If the license you use for your software does not allow the things as described by those definitions, you can't call it Open Source or Free Software.

Yes. It is absorbed by moisture in the atmosphere. That limits its range, which is great if you want to setup lots of cellular towers without them interfering with each other.

on edit: one reason the specs are not enough is generally specs will tell you what needs to be implemented but a good book, like these ones, will tell you how it has been implemented or what the spec implies for implementation and what all that will mean for you as a user of the language.

> This very idea lead to several prominent Stoics to commit suicide, because might as well hasten my eventual ceasing of being?

Can you please cite a few of these prominent Stoics? Notwithstanding exceptional circumstances, suicide in general was not held in particularly high regard by the Stoics. As Epictetus has it[0]:

The following is another way in which the minds of those are affected who hear these precepts amiss. For example, a friend of mine for no reason at all made up his mind to starve himself to death. I learned about it when he was already in the third day of his fasting, and went and asked what had happened.—I have decided, he answered.—Very well, but still what was it that induced you to make up your mind? For if your judgement was good, see, we are at your side and ready to help you to make your exit from this life; but if your judgement was irrational, change it.—I must abide by my decisions.—Why, man, what are you about? You mean not all your decisions, but only the right ones. For example, if you are convinced at this moment that it is night, do not change your opinion, if that seems best to you, but abide by it and say that you ought to abide by your decisions! Do you not wish to make your beginning and your foundation firm, that is, to consider whether your decision is sound or unsound, and only after you have done that proceed to rear thereon the structure of your determination and your firm resolve? But if you lay a rotten and crumbling foundation, you cannot rear thereon even a small building, but the bigger and the stronger your superstructure is the more quickly it will fall down. Without any reason you are taking out of this life, to our detriment, a human being who is a familiar friend, a citizen of the same state, both the large state and the small; and then, though in the act of murder, and while engaged in the destruction of a human being that has done no wrong, you say that you "must abide by your decisions"! But if the idea ever entered your head to kill me, would you have to abide by your decisions?
