Compressed elliptic curve points is not some crazy secret or complex thing to be making up conspiracy theories about. The nature of elliptic curve cryptography is that knowing the curve and the x coordinate, there are literally only two possible y coordinates, and a single bit signals which of the two possible y coordinates to use, allowing you to reduce, say, 512 bits of key coordinate down to 257 (256 for the x, 1 for the y), at a trivial cost to compute y from x before doing the rest of the math.
The only reason this wasn't done automatically in every implementation of elliptic curve cryptography from the beginning is because some idiot at the patent office issued a patent for point compression (that is, one specific case of selecting one of two options with a single bit), and so for a couple of decades free projects didn't want to risk implementing it for fear of patent trolls. The patents have now expired, so people are doing the sensible thing.
> Credit card processing fees are high in the US, typically 2.5%
Wow! I had no idea. It is typically 0.6% here in Oz. You are being ripped off.
It's become just another form of wealth transfer from the poor to the upper classes in the economy. Perks and incentives to earn "points" and cash-back by spending on credit cards are financed by those merchant fees, so the entire country is subsidizing them by paying hidden fees in the form of higher prices of goods and services. People who buy a lot with credit and can easily pay off their credit card bill every month come out ahead. People who can't or don't purchase much or who cannot always pay their bill in full get screwed. And card networks (Visa, Mastercard, etc) are leeches in the middle sucking blood from everyone.
Once you understand how the system is rigged, it's actually pretty disgusting.
Like letting people make their own choices? How is letting someone choose to sell or eat a Slim Jim immoral?
Because the processed food companies deliberately design their products to be as addictive as possible. As a society we (correctly) recognize that drug dealers bear some responsibility when users overdose on drugs, and cigarette companies have lost lawsuits because they knowingly sold an addictive and dangerous product while pretending it was perfectly healthy. Processed food companies are doing the same, even deliberately targeting children. Their products may not be *as* harmful as drugs or cigarettes, but they are still harmful and deliberately addictive, and they ought to bear some of the social responsibility for the damage their product has done (since they reaped **all** the profits). "Privatize the profits, socialize the losses" has been going on for a looooong time in this country, and it's pushed this country to (and perhaps past) it's breaking point. Freedom of choice is all well and good, but it requires people to be properly informed, and to actually have a choice (which many people, especially those living in food deserts, who tend to be poor and not well educated to begin with, do not).
I want them to bring back Slashdot subscriptions. I'll happily pay to support Slashdot, but I uncompromisingly reject advertising. Not to mention, the few times the newer ads have gotten through uBlock filters they've been atrocious.
I know the site has been on life support for a decade but subscriptions seem like a pretty easy way to make some money.
Function reject.
