No. That is not the only way... Alternatives include: charging more interest on loans then on savings, charging service fees for each transaction. Also just think about this for a second. If the economy keeps growing (which is what inflation really is) more people will have more money, they would want to keep that money somewhere. They put it in a savings account. The bank now has more money to pay more interests.

The point is that some retired professor in microbiology takes a little lamplight making claims about covid, which unfortunately are factually utterly and desperately wrong.

That's the "appeal to authority" fallacy, which you could call out.

Extensive use of fallacies is in the active repertoire of demagogues. That's why it helps to study them, a bit, so you recognize a skunk if you meet it in the wild.
> If people are free to practice Islam then they must also be free to choose not to practice Islam and require interest on loans.

That's not the point of discussion. The argument is that we have known for literally thousands of years that charging interest on loans is a destructive practice. It's banned in Islam, Judaism, and Christianity for a reason. Yet we cry today at the mess we're in, as if we didn't know any better.

> They are contractually owed a payment. Its not profit until expenses are subtracted. And there is always the risk that the other party does not return the money.

They're owed more money than the capital. That's what is prohibited. It doesn't matter if it's profit or revenue. Banks operate and generate ridiculous profits on this basis.

> It seems you may have identified a problems with the law then.

So the law can't protect the contract? What's the point in writing a contract then in the first place? Take that away and no business contract makes sense anymore since it can't be enforced by the law.
While true, the plus side is EVs are still a net CO2 win even when charged by dirty fuel.

As part of the same topic, I think we’re going to see PV-covered EV cars in the not too distant future; not because they don’t need charging (they’re about 10% of your instant needs on the move), but because adding PV reduces the pressure on the grid, and will significantly reduce the need to install power lines to sunlit car parks.

Home, multi-storey, and hotel/motel parking will still almost certainly still need power.
Overnight (morning of 1/30/2021), the Texas grid [1] received 20,000 MW (average) of wind generated energy. If all Texas cars, or 9 million, were Battery Electric Vehicles (BEV), the wind turbines (at the 20,000MW rate) would end up supplying 46% of the electricity to those cars if they plugged in last night.

Now, last night was exceptionally windy. However, wind turbines generation is growing by about 10-20% annually. Accordingly, in a few years 20,000 MW overnight wind generation will become the Texas median production rate or even will fall among the lower percentiles of production.

The article that the NY Times references [2] shows how the 100% electric fleet demand compares to the current daily load profiles in Texas and California. The Texas grid, as depicted, shows a peak at 3PM -- for now. However, if there were 100% EVs, that peak would shift to 3AM. Then, in addition to the typically abundant wind energy, natural gas (peaked) generators could come online to easily deliver more power.

Something like 60-70% of Texas daily wind generation occurs between 9PM and 9AM, because of the diurnal wind patterns. This means that the usually strong nightly winds allows Texas to outproduce electricity at 3AM as compared to 3PM.

In contrast to the habits of California EV drivers, Texas drivers get 80-90% of their annual charge needs by plugging in overnight at their homes. So, the Texas grid is uniquely suited to host a rapidly growing EV fleet.

[EDIT] 9,000 MW would provide 1 kWh for 10 hrs for each car of 9,000,000 EV cars to get 30+ miles of range. So, yeah, last night the Texas grid could accommodate all of them.

The article is about pure math, which is the foundation of mathematics using sets, topology, etc. It has separate classes, textbooks and professors from applied mathematics, and often a very low courseload because of the difficulty (like 24 hours per week.)

From a simplistic standpoint, pure math is not focused on equations or numeric solutions, unlike applied mathematics. (You don't need a calculator for most pure math classes.)

What a great explanation. Thank you so much!
Great development! I'm certainly all for this becoming the standard/default. Unfortunately for those relying on fsync() flushing the whole file system (which one shouldn't) syncfs() isn't a great replacement. Last time I tested that it didn't return errors on failure nor was it making certain all changes to the file system before syncfs() made it to disk.

Btrfs had this "fast fsync" for a while already btw. (out of necessity -- otherwise fsync would be even more unbearably slow on btrfs). This seemed to be difficult to implement (lots of corner cases). Every release there were "fast fsync" bug fixes such as e.g. https://lore.kernel.org/linux-btrfs/20200220132949.20571-1-f... https://lore.kernel.org/linux-btrfs/20200722112837.15516-1-f... . Let's hope the ext4 version of this has less initial issues.
But what kind of reasoning is on solid ground when we’re talking about logic... outside of math? Saying logic here is almost lying to ourselves because we’re not expecting anyone to create logical chains of reasoning.

Do mathematicians even use logic as a reasoning tool, as opposed to a proving tool?

macOS is not, has never been, and will never be linux compatible. It's a unix, linux is a unix, if you're looking for a unix it will work just fine. It will not work if you're looking for a linux, you'll have to go through a VM with all that entails.
I'm pretty sure YouTube uses QUIC for video streaming today, which is a similar workload to ours.
As a hack, if you can't use a uniwidth font, you can simulate bold font by having a `text-shadow` of the same color offset 1px to the right.

This is helpful for UI elements that need to become bold when selected.
There are plenty of sources, but here’s a recent one that touches on a few points:

Alternatively, choose UI design ideas that don't involve changing the font weight on hover. What's wrong with changing the colour and/or background instead? Or (for an element like a button) give the element a fixed width that is sufficient for either weight of the text.

Sometimes, if a design idea turns out to cause problems, maybe it's time to reconsider the design.
I was a happy owner of the 1+ 2, 1+ 4.
I'm now using the 1+ 6 and I'm glad to hear there's an upcoming Linux support.
The thing is, my first two phones were stolen, so sometimes you don't really have a choice.
The hardware is nice, and until a couple years ago there was nothing available in the PC world that matched it, but it's the best mainstream GUI experience on the market today. I use macOS, Windows, and Linux every day. Windows and Linux's GUIs lack little affordances like a document icon on a window that you can drag and drop.

Plus there is nothing equivalent to OmniFocus outside of macOS, and that is one of the tools I depend on most heavily.
EDIT: In fact I appear to have paraphrased the next post in the series, https://fsharpforfunandprofit.com/posts/removing-cyclic-depe... . Probably go and read that instead.

One pattern this nudges you towards is having a Domain.fs at the top of each project. Since everything in your project wants to talk in terms of the data types you've modelled, it makes sense to put them all in the same place at the top. Moreover, once you've done that, you're guided towards having your data types really being "dumb" - algebraic data types only - because to put actual behaviour into them is harder when all you have is definitions of data types (and no associated modules). You certainly can write OOsagne using the Domain.fs pattern, but it's much harder and the code really smells when you do (because the domain file gets super long).

The upshot is that your domain model appears explicitly at the start of the project, which is a big win for anyone who comes into the project and needs to learn quickly what's going on. By contrast, nearly all the C# I've ever come across has the domain spread across many files and all mixed up with implementation details.

This is certainly not the only way to write F# - I've written projects which have the domain spread across multiple files - but it's one nice way to handle a small-to-medium-sized project.
And the FAA (or similar agency) should be involved with literally every rocket launch! Especially if it's a test!

What exactly is your point here?
In this case, the problem is that the Recursive font doesn't actually contain the Arabic and Japanese characters, so the browser is falling back to another font. If you use a uniwidth font that actually contains all the characters, this should work.
I agree with this.

In my opinion, if you have to state multiple times in your plan that what you're planning isn't illegal/manipulation, it's very grey at best.

The fact that one of the premises presented here for the price going up is "We buy a bunch of options, to force (ie, manipulate) someone else into buying the stock, so that the price can go up" doesn't boad well for a "it's not market manipuation" argument either.

Straight from this post:

> It looks like this: RH Call Option buying -> MM Delta hedging/share purchase -> short squeezing -> Greater retail/RHers price action chasing/call option buying -> MM Delta hedging/share purchase -> short squeezing -> Institutional and new channels flip the script -> GME to $400+

They've presented a chain of events that starts only with "We try to buy a lot of it", has a bunch of "other people have to buy based directly on our actions", they even through in a "other people see the price going up and try to pile in" (ie, screw the rest of retail).

> the extent of their sympathy for the little guy will determine the outcome

I don't see the masses of people ending up facing consequences here. I wouldn't be surprised if a group of WSB pushers who made out like bandits do see consequences. I also think it's going to be difficult to consider them the little guy if they make a bunch of money, and the much larger mass of non-WSB retail lose their shirts.
You do you, but I’ve never understood this. Semi-remote arrangements seem to me like the worst of both worlds; you have to live close enough to the office for a reasonable commute 1-2x a week, and you’ve got to pay for enough space to work from home. Since you’re staying within commuting range, you probably won’t be able to get the really cheap housing.

I’d rather live in a small apartment and close to the office, or full remote and leverage different housing prices.
ClumsyPilot mentioned this, but it's worth repeating - if your load is expecting AC power but is converting it to DC (eg computer power supplies) you can probably save quite a bit by looking at fully-DC options so you skip the DC-AC-DC conversion stages.

Possibly more urgent policy reforms/legislation required in India than this:

1. Codification of the law of Torts.

2. No-fault divorce.

3. More devolution of powers and policy making to states.

4. Ending the practice of Unelected Governers.

5. Remove power of the central government to dismiss elected state governments.

6. Dismantle the British Era civil service designed to preserve undemocratic control over the population to a modern federal system where all decision making authority lies with elected representatives only.

7. Repeal of colonial era police and criminal codes, and moving to a more humane police and criminal justice system as in other democratic countries, including the establishment of jury system.

8. Give equal representation all states in the upper house as in the US senate(2 senator s from each state).
Language constraints aside, the real world is not something that can be cleanly modeled without the notion of circular dependencies between things. Not very many real, practical activities can be truly isolated from other closely-related activities and wrapped up in some leak-proof contract.

Consider briefly the domain model of a bank. Customers rely on Accounts (I.e. have one or many). Accounts rely on Customers (i.e. have one or many). This is a simple kind of test you can apply to your language and architecture to see if you have what it takes to attack the problem domain. Most approaches lauded on HN would be a messy clusterfuck when attempting to deal with this. Now, if I can simply call CustomerService from AccountService and vice versa, there is no frustration anymore. This is the power of reflection. It certainly has other caveats, but there are advantages when it is used responsibly.

If you want to understand why functional-only business applications are not taking the world by storm, this is the reason. If it weren't for a few "messy" concepts like reflection, we would never get anything done. Having 1 rigid graph of functions and a global ordering of how we have to compile these things... My co workers would laugh me off the conference call if I proposed these constraints be imposed upon us today.

It appears to be a PostgreSQL bug from my reading. The return code causing the problem has always been legitimate, even though you never expected to see it in practice.

I did a quick check of the source of two other storage engines that run on both Linux and macOS to see how common this oversight is. They both had code for handling this case correctly for years. It was probably never used, but it was implemented because the syscall docs allowed for the possibility.

This is the kind of thing I would have assumed PostgreSQL handles correctly as a matter of pedantry. Given how syscall heavy PostgreSQL is, it will be a fair amount of work to fix it.
Many of the professors I admired were top notch researches as well as great teachers. They go together more often then not.

Apple has a hard requirement that you use the safari rendering engine for all browsers. So even Firefox on iOS is really just reskined safari.

I don't have an anti for Balicer, so I don't care if his models are right-or-wrong. It's natural to have mistakes, and changing position after 'only' 3 days is fine enough. I also agree that we heard some good news, but I do think that the 95% RRR is relevant - people who have a strong enough immune reaction to make the disease asymptomatic are people who have been protected. Once enough people have been protected, than hospital burden will go down and Israel could manage this thing.

I don't take a position on that, but if it's not common, then why are we treating it like a big deal to require police officers to tell the truth to us?

My premise isn't that lying is either essentially human or completely wrong -- my premise is that police officers are humans like the rest of us and should be able to handle at least the same restrictions as everybody else. If I'm expected to know the entire law, they shouldn't be able to hide behind ignorance as an excuse either. If I'm expected to tell the truth, they should tell the truth as well. If I'm expected to deescalate tense situations, they should have the same expectations.

A cop should be at least as well trained and conscientious as a civilian (and hopefully more trained since this stuff is actually their job).
No, but if a law is applied inconsistently it raises questions about whether 1) the law is sensible 2) the regulatory system is unbiased. Pointing to such inconsistencies is a perfectly reasonable thing to do.
> Horses for courses. Is anyone suggesting QUIC for gigantic bulk transfers?

Anyone who's looking to replace HTTP/1.1 and HTTP/2 with HTTP/3? AFAIK QUIC is completely integral to that, in order to avoid this issue you'll need a mixed deployment of HTTP/3 and an older version of the standard.

I’ve played around with F# over the years, but have only recently started getting into seriously. The top down nature of dependencies (both within a given file and for the files within a project) is a little odd at first, but once you get used to it feels quite natural.

If nothing else, it encourages (somewhat) common ways of structuring projects and avoids a lot of bike shedding about separation of concerns and project structure I encounter in C#.

Nice article. The first thing that came to mind when seeing the title was "but circular dependencies just mean that your layers are wrong and those should all be in the same layer" and funnily enough that's exactly what's explained in the article!

What would be interesting would be to organize modules into named layers--instead of just explicit 1-by-1 module dependencies (i.e. edges). I have not seen a language do that yet.

Another interesting thing that I haven't seen touched on in more mainstream languages is the idea of bidirectional interfaces. The somewhat DSL-like NesC language had this, primarily driven by the need to write device drivers that serviced interrupts (and events).
