The compiler causing undefined behavior on its own reminds me of one of the fun bugs we found[1] with 32-bit x86 clang where one compiler pass fools another into thinking there's an undefined behavior by combining three struct field in

That's wishful thinking. I can't say much about the Soviets, but the regime in Iran, or at least a chunk of the people in power, understands how to balance their power and freedom (critically the "freedom to get rich", d

Perhaps "trustworthiness" is not the best word for the concept. I'm not sure mechanical hardware is more trustworthy (mechanical stuff also fail often and can be unreliable), but their behavior is somewhat more malleable by t

I'm not sure lack of wisdom is a fair characterization. It does not look like they have functionality regressions caused by new features in other sections of the car. Had the new features ruined some old ones, I would have agreed with

MacBook has always had only one RAM option and came with it: 8gb. No 4gb or 16gb ever. The article is incorrect: they made an orthogonal change to MacBook Air (13" only) in making 8GB standard (which used to be an option).

I did not look hard, but didn't find an obvious location to remove the SIM from my Mercedes. It is certainly undocumented in the owner's manual. Note that [depending on the modem], simply removing the SIM might not be enough to t

He mentioned it has autopilot hardware standard (like the current Model S), which makes me suspect you have to pay a few thousand dollars more to unlock it in software.

I believe most modern cars you buy today (even low-end ones) have a GSM modem connected to a phone carrier which is probably active regardless of your payment for the "connected" features, so not much better unless you figure out

Sure, "shareholder values" is not the same thing as bottom line profit and it might be subjective depending on a number of factors, but it is also not the same thing as value to the broader society; it can be at odds with it depen

While I agree LetsEncrypt is awesome, the certificates are actually shorter-lived (90 days), I believe, than the former CAs that issued certs for free (e.g. StartSSL) that offered a year of validity. The rationale is replacing the keys soon

They have at most 48 hours (or perhaps 24?) and 5 tries to find your fingerprint and unlock the device. TouchID will discard the keys and require a passphrase if it is not used for a while or after the fifth invalid fingerprint attempt. The
