There exist certain classes of prime numbers that should not be used for some cryptographic operations because algorithms exist that reduce the computation required for factoring attacks. This more often applies to cases where smaller primes are applied. Sources for this king of knowledge are mathematics or cryptography textbooks.

For other cryptographic operations, almost any sufficiently large prime can be used. Even a 50% reduction on a computation that will take trillions of years, has no practical impact.


The definition of organ in this article is closest to the body part definition. The use of organ here relies on a less common definition: roughly a constituent part of some larger whole that performs a specific function.


Not just a specific function, but a necessary function. Usually, without an organ, the organism won't survive. So your fingers aren't organs, because you can survive (with some difficulty) without them, but without your stomach or heart or skin, you'll die.


I think that’s a great summary.

As a native English speaker, it was understandable but feels rather foreign because you never hear parts of computers referred to that way these days.


It likely contains a bug but is an uncorrupted file. Corrupted to me means the file was changed or modified in a way from it's intended state and likely won't run anymore.


Yes, driven by local data collection. More tightly packed ground stations and the availability of atmospheric measurement at various altitudes will improve accuracy.


Also, the weather is just a lot more predictable in some areas than others.


I think it's mostly this. If you look at a weather radar map, sometimes you see a speckled pattern of rain where there is heavy rain in places, and 100 yards away there is no rain at all. No way you can predict that multiple days out.


I feel this living in the path of moisture coming from the Gulf of Mexico. My phone has gotten good at letting me know when the rain will start and stop to within a few minutes, but whatever data source Apple uses still struggles with near-term prediction (day+) in the summer when there are random popup storms all the time.


This. Just some days ago I had a conversation with meteorologist who said exactly this - the weather has never been easy to predict in northen Europe and it has become even less predictable with climate change and global warming.


Moving from Phoenix to Austin was a bit of a shock. Weather prediction in Phoenix is essentially perfect. In Austin the forecast seems much less accurate.


The article discusses the length of the bottles placed end to end. Although I agree the title isn't clear.


Lyft likely cost customers' funds though a poor process like this in the past.

One could create an account, hail rides and add their own payment method while still being associated with someone else's email. Ride recipes would then be sent to someone else's email where the receiving party could add or increase a tip through an unauthenticated link and have it charged to the riders credit card.


If law enforcement ever busts a scammer and discovers a tool like this was essential to the scam, that would generate lawsuits.


True


True. Expected to remain solvent would be more clear.


What is the recommended upgrade path for macOS' system install of git?

I have upgraded my brew install, but am unsure of what to do with the vulnerable system install.


I don't think macOS comes with git; like, it might actually come with a git binary, but that binary is just a "shim" that runs an actual copy of git from an installed copy of Xcode. If you want to upgrade what is conceptually that copy of git you can thereby upgrade Xcode. (If you haven't installed Xcode then it might have come from a related package called Xcode Command Line Tools that doesn't include Xcode.app; if you run these shims and don't have Xcode installed it offers to install this package for you automatically.)


I'm guessing a system security update will patch the git executable. No way would apple make you update Xcode just for this. (Well, maybe...)


Couldn't Twilio also close and cease providing service to any accounts that initiate chargebacks?


They could, but customers could then file complaints with the FTC and their state’s attorney general for the fraud Twilio is enabling.

I strongly encourage Twilio customers to pursue this route if Twilio is charging them for fraudulent charges.


Further, the customer has the right to dispute credit card charges thanks to the agreement between customer and card provider and between card provider and merchant.

Twilio will get in trouble with Visa/Mastercard if customers say Twilio is dropping them for disputes the card provider finds in the customers' favor.


> Twilio will get in trouble with Visa/Mastercard if customers say Twilio is dropping them for disputes the card provider finds in the customers' favor.

This isn't true. Visa/Mastercard care about your chargeback rate. You can block a customer who's done a chargeback. I'm sure the card networks have rules around what you cannot do as a result of a chargeback but you can stop providing services to a customer who has done a chargeback.


Disclosure: I engineered and delivered a high risk payment processing gateway to a firm specializing in being a cc processor of last resort, also working with merchant banks of last resort.

To be clear, my views on this are not legal counsel, they are simply from having worked in this area for a decade before becoming CTO at a global bank.


These filings may add up to change at some later time, though are unlikely to provide any kind of near-term actionable remedy.


Such is America’s regulatory landscape ¯\_(ツ)_/¯


If they lose the contract with their credit card company... I see people jumping out of windows at the Twilio HQ.

That’s like nuclear meltdown.


To lose the ability to process MasterCard or Visa credit cards takes a few months. You can rack up big fines during that time though. If they get put into the probation period that would raise red flags with some execs, assuming people are communicating these things.


Maybe they will get surprised, because people live by „don’t ask, don’t tell“ and when shit hits the fan everybody acts surprised.


Customers can do that anyway.
