> It was my understanding that in the current system merchants tend to eat the cost of fraud under our current system (see charge backs, rolling reserves, etc.)

1) A significant portion of the cost of chargebacks is administrative, especially for small transactions. The banks at least nominally attempt to prevent customers from defrauding merchants, even if they fail more often than not, because if they didn't even try it would get a lot worse fast. But that costs money, and the money it costs is proportional to the amount fraud/chargebacks and not linearly proportional to the purchase price. Having to go through the chargeback process over a nickel is not something they're about, hence the minimum transaction fees. They also sometimes lose the money because it's not possible to recover it from the merchant for some reason.

2) If you're trying to become a payment processing system with low transaction fees which people can transfer money into using their credit cards, the "merchant" who eats the cost of fraud is you.
Non democratic systems fail in other ways, but it's true that they don't have the next election to worry about, and they can have a longer planning horizon.

The planning usually benefits the ruling elite more than the people, but it's still a real point.

The astonishing rise of China last 30 years has made me accept that it can actually work out occasionally!

> Advertisement as implemented today is a privacy hazard, but there are other ways to do it, client-side, which is what Cliqz attempted.

https://en.wikipedia.org/wiki/Cliqz#Integration_with_Firefox: "According to the Firefox support website, this version of Firefox collects and sends data to the Cliqz corporation including text typed in the address bar, queries to other search engines, information about visited webpages and interactions with them including mouse movement, scrolling, and amount of time spent; and the user's interactions with the user interface of the Cliqz software. This data is tied to a unique identifier allowing Cliqz to track long-term performance."

Yep, real "client-side", eh?

Even if it was actually client-side, that's cold comfort; the data's still being collected and presumably persisted, and there's no telling whether or not some future software update will make that locally-stored data not-so-locally-stored anymore.
HTTP 101: do not transfer anything you don't want 'cached' as a GET request. Not only that, but some browsers will pre-emptively send GET requests or retry them so you'd have the double headache to worry about duplicate requests on the server-side.

It shouldn't require much experience to know when to use POST or some other HTTP verb - banks certainly have no excuse.
Yes, but this is far out of the context of this discussion. This topic has nothing to do with entering into an absurd unenforceable contract.

Investments offer different terms to different customers. Those with fewer privileges are worth less, and you should be willing to pay less or not at all.
This is not employment, or personal housing, this is a purchase purely for future financial gain, for which markets offer countless alternative offerings.

So, I just went and took a look. US deaths from influenza have ranged from 12,000 to a high of 61,000, with an average of more like 30,000. So, if we had prior knowledge that we would have a season with 150,000 deaths, which would be unlike anything we've seen since at least the 1950's and maybe longer, I expect that the government would indeed take some evasive action. But that's still not the right comparison. For covid-19, we were looking at somewhere between 750,000 and 2 million deaths. In other words, 20-50 times more than a typical flu season.
But the skills to build low-volume, high-margin fighter jets are distinct from the skills to build high-volume, low-margin toasters. They'll be some overlap, don't get me wrong, but quantity has a quality all of its own.
Well this is certainly the coolest thing I've read today. I've been trying to grok closures and this helps a bit. Is there a reason to not use the global hash table itself to store the state instead of a closure? This seems to be trading a database with memory. This also seems to be harder to interrogate, what if I want to go in and see what's currently outstanding, instead of going to Firebase, I'll need to go through the hash table and check the content of the function.

I think I may be missing something someone who's actually worked with lisp can see, to me closure, recursion and functional programming is cool but I can do everything its showing off using the standard fare of loops and databases.

That makes sense as far as it goes. But it also means that you are implicitly relying on the existence of other organizations to train people to a level where you feel you can hire them. That's OK, as long as you don't try to deny this. Why do I think that's important? Because those other organizations are carrying the costs of training for you. Should they want some sort of social payback (of any kind) to reflect this, it seems wise to me that you'd recognize the benefit that you accrue from this sort of thing, and be supportive of it.
> isn't a single entity

Maybe, but it mostly behaves as one hivemind.

That's the point, it doesn't. TheGuardian along with the rest of the traditional media spouted the same propaganda for a while. It's easy to spot if you pay attention.
Exactly, why are young students footing a disproportionate load for “society-benefiting research” as part of their tuition? And paying interest for it. That’s amazingly unfair.
> GE boasts 62 percent efficiency with its combined cycle gas plants using its H-Class turbines

That's huge! Normally generating electricity from fossil fuels is about 1/3rd efficient.

Further more: If we assume, with grid loss, that the whole system is 50% efficient once it reaches a home, and we pair it with an older 2.7 COE heat pump, it means that home heating with a heat pump, when using GE's new generator, is 135% efficient. (A typical gas furnace is 90-ish.)

For those who don't know: A heat pump has greater than 100% efficiency because it sucks heat out of ambient air. It cools the outside air to heat the inside.
Looks useful. I really dislike the "Download Postman and then you will have documentation" approach. Documentation lives on the web, and there are better alternatives to Postman anyway.
for a house in my neighbourhood I'd guess ~100 mg
Hmm. The idea is tempting, but I'm wary of the notion that most students (especially underclassmen) could make efficient use of their time trying to create a whole business from scratch in 6 months. Is this a reasonable assumption? There is a limit on the number of open problems that can be addressed with whizbang junior CS projects, no? Especially if you're aiming for said projects to be educational in nature.

Additionally, might a 6 month break from schooling result in a more severe version of summer learning loss[1], disadvantaging these students when they do eventually re-enroll?

On the other hand, paying full tuition for even a partially online semester is definitely not an attractive prospect, not to mention the opportunities one might miss out on by having one less "full" semester. Tough choice.

So I'm not too familiar with Australian humor or comedians, but this is still pretty funny to me (am American).

Humor aside, this is actually a pretty decent PSA. When this all started I do remember how the frozen food aisle looked: it was completely emptied out and I remember thinking that cooking these kinds of things on your own is, like this guy says, a) cheaper and b) better for your health.
That's the thing you should be working on.

You should understand the system both technically (how is it architected, how does it work, what does it do) and from a business standpoint (why does it do that? where is value derived? what is painful?).

It's hard to add value if you can't be entrepreneurial or innovative.
Can we force them not to collect this info via the recently passed CCPA in California?
This is the only intelligent move ICANN can make, especially considering the public out lash (including from state officials in CA). It's actually astounding that the organization managing .org actually thought they could get away with bold-faced cronyism so clearly opposed to the principles of the internet. That said, we certainly have to watch out for more acts like this.
It's an actual kernel the same way a virtual machine is an actual machine.

To unpack that: a virtual machine could be a real machine, it just happens to instead by a software-hosted emulation thereof. There's a hardware JVM in your SIM card, for an example.

arvo (the kernel) is the same deal: there's nothing stopping someone from implementing the syscalls it uses (used to be seven of them IIRC), writing some drivers, and running it on bare metal.

But that's a lot of work, and the Unix-hosted virtual kernel works well enough. The whole thing may be fairly compared with inferno, which is a hosted plan9 which runs on a VM.

The fact that the central authority made the right call in this instance doesn’t ultimately mean that the central authority isn’t still dangerous.

I hope this serves as a wake-up call to everyone who got scared by this.
I am incredibly surprised to see this good news. Finally an organisation made a decision that was in the public interest. Hopefully more decisions like this can be made in the future.
>But only variants can be null or empty...

That's true, only Variants can be Null (Null is a state of Variant); however, Empty is translated to whatever default value makes sense for some of the (non-Object, non-user-defined) data types:

Dim s As String, d As Date, x As Single, y As Double, i As Integer
s = Empty: d = Empty: x = Empty: y = Empty: i = Empty
Debug.Print s, d, x, y, i

(The above compiles and runs, and - no surprise - numerics are made zero, and string made "".)

>I'm sure someone has complained about Oracle's idea that empty strings are null values.

I have certainly complained about that: I mean, what's not to love about conflating "this field intentionally left blank" with "no certain value could be obtained for this field"? /s

>...a rant about how nulls are a terrible offense against the true relational model...

By way of Wikipedia, found this: https://www.dcs.warwick.ac.uk/~hugh/TTM/TTM-TheAskewWall-pri.... A fine read. I am left wondering about how OUTER JOINs would be handled without NULLs. I am now also wondering if it was OUTER JOINs that made NULLs seem necessary.

Many serfs could not legally leave the land they were attached to and did not have freedom of movement. Part of the value of that land when it was sold or traded was the serfs bonded to it. This shouldn't be particularly surprising because even some knights were owned by Lords and could be traded or given as gifts to other Lords.
Not just the last few years. Bay area mortgages have been jumbos for decades. When I bought my first house in San Jose for $325K in 1994, the conforming loan limit was $200K.
Your voice matters! This victory was largely because of collective action on behalf of the people making such a fuss. Anyone who wrote to California's Attorney General should feel really proud of themselves right now; letters like yours likely directly caused this.
Skiena's book is universally acknowledged to be great, but as you point out, it costs US$33 in the US, not US$150 (though Amazon tells me it's US$52.06, so I guess the price isn't very stable), and it isn't one of the ones that comes out in a new edition every two years with the problems slightly tweaked; it's in its second edition and its 23rd year. So it's an example of the dynamic I'm talking about, not a counterexample to it.

I'm talking about things like https://www.amazon.com/Computer-Science-Overview-Brookshear-... (Brookshear & Brylow), which Amazon tells me is US$155.49 for the Swindle or US$79 in paperback (new) and is in its 13th edition after 35 years; the first edition was evidently in 1985, so they've averaged roughly three years per edition. As far as I can tell, the only novel work Brookshear has ever published (not counting textbooks and papers about teaching) was a two-page paper in 1978 on projective prime ideals; and Brylow is hardly a more accomplished researcher, having published a couple of papers about formal methods for real-time software in 2001–3 and a few less-cited papers up to 2012. However good the book was in 1985, I wouldn't consider teaching from it today.

Skiena's book is an example of a really good textbook. Brookshear's book is an example of paying more. I did try to find a book like that about algorithms and data structures, but unsuccessfully; the closest I could find was Brookshear's chapter 5, which spends 50 pages to cover Euclid's algorithm, sequential search, insertion sort, and binary search (as well as, lamentably, bubble sort), all in terrible Python and 1958-style flowcharts, while giving terrible programming advice and performance numbers so wrong they weren't even right in 1985.

It's true that this kind of thing is limited to entry-level courses and more popular majors, as far as I can tell. Upper-level STEM courses don't attract enough students for it to be worth the effort to rip them off this way, even for world-class ripoff experts like academic publishers.

India has a significant advantage over Perú, Egypt, or mainland China, in that English is a second language to most of its population but not a foreign one, so the translation obstacle isn't nearly as serious.

I think of it as being similar to healthcare. People need education to get jobs in the current economy. (In the same way they need healthcare to stay alive) You might make it so expensive they can't pay it back in any reasonable amount of time but if the choice is job vs no job - people gonna take it. If you remove the ability to even get an education (or healthcare) by saying you can only get it with cash then you're just screwing people over.

Regardless if job requirements change (they only will for a subset that no one cares about and no one is trying to get), you're going to screw people over. The lag time between no-loans and job-requirements dropping is going to be too long. There will be a lot of people who fall into the cracks and will be stuck with the lowest tier jobs because they couldn't afford a cash-only education until it was much less expensive.

Regardless of this - I feel like this is the wrong approach to debate lower costs vs no loans vs whatever-where-a-student-pays-in-the-end. I think 4 year college should be free (no tuition, books paid, stipend or special housing, etc.) given how the world works. I went to college for free due to CH 35 of the VA and it was really the only reason I was able to do it and fully commit to it. I have no problem with having a more educated populace - regardless of what they study. I did study something that came with very gainful employment but that wasn't obvious in the beginning of my studies. I think 4 year college would be less necessary if we had better education from the start - but we're never going to get there in this country.

You are not capable of writing a PhD chapter. You lack the basic scientific thinking or method required. I suggest you focus on your core competency - chuckling.

Here is some basic reading material for you. Lets see if you can follow this

https://hackage.haskell.org/package/async-2.2.2/docs/Control...

do a1 <- async (getURL url1)

a2 <- async (getURL url2)

page1 <- wait a1

page2 <- wait a2

This implements async await in Haskell via a library using Monads. Hint: you cannot do this in C via any library. You need to modify the language. If you are uneducated about Monads, you might think this is similar to some kind of C code. It is not!

Here is the same do syntax being used to parse source files instead of doing async/await IO. Yes this parser will also perform backtracking etc, which will not be obvious to anyone who thinks this is some kind of transliteraton of C

https://markkarpov.com/tutorial/megaparsec.html

mySequence :: Parser (Char, Char, Char)
mySequence = do

a <- char 'a'

b <- char 'b'

c <- char 'c'

return (a, b, c)

Hint: If you want to do something like this in C, you use yacc/bison, a parser generator tool - there is no library. And it is fucking ugly.

Hint 2: There are monads for parsing, async IO, exceptions, nondetermenism, monte carlo .........

Hint 3: The parser libraries are 25 years old.

Hint 4: Monad libraries represent less than 1% of PL research over the last 40 years.

Hint 5: C# LINQ is basically a Monad.

Hint 6: When confronted with something you don't understand, it is better to be quiet instead of opening your mouth and advertising your ignorance.

Hint 7: If your conversational style consists of chuckling and providing "Hints", be prepared for receiving a taste of the same medicine.

The Hornsdale battery in South Australia gets talked about on the news on a regular basis, as in pretty much every frequency stabilization event gets written up with how much better it was than the spinning metal that's also contracted for stabilization in that part of Australia.

BTW you might also note that HVDC and DC-to-DC interconnects are becoming popular. If your theory about batteries being bad for frequency stabilization were true, they'd also be big problems.

There are other solutions around authentication that would be perfectly fine and still privacy-conscious. It's just that anything other than forcing you to login using a Google account doesn't mesh with their strategy of ensnaring users and adding to their all-encompassing profile of you.
There's still no evidence that Amazon has ever done this. AFAIK potential customers are more concerned that AWS will use utilization metadata as a proxy for their customers' financials, like Facebook was using Onavo traffic data to decide which startups to buy and which to clone.

This isn't a new problem, for eg web hosting companies have been selling Apache/PHP hosting for decades. Apache and PHP were made more useful because of that reselling rather than being negatively affected by it. I think the only difference now is these OSS companies are VC backed so they have to get huge growth to pay back their giant loans.

I watched a talk recently that argued that Amazon increases the size of the market available for the software the OSS companies are producing. So the pie increases in size and the result is likely to be more money available for the software, not less.

The OSS companies you refer to are more about using OSS as the new shareware, a loss leader or poison pill to sell proprietary software, their business model isn't about open source at all.
