Certificate revocations are not required to be reported after the expiration date, so you can no longer reliably check if a certificate has been revoked (e.g., because its underlying key was exfiltrated or because it was misissued).

Honestly, the Fourth Crusade in 1204 was more of a "real" death of the Byzantine Empire than the conquest of Constantinople in 1453. Although the largest remnant of the Byzantine Empire was able to reconquest Constantinople in 126

I've been trying out AI over the past month (mostly because of management trying to force it down my throat), and have not found it to be terribly conducive to actually helping me on most tasks. It still evidences a lot of the failure

There are three main problems with trying to offer a simple answer to the question of "what is the first computer?" The most obvious of the problems is that a computer isn't a singular technology that springs up de novo, but

There is a decent legal argument to be made that §230 doesn't immunize platforms for the speech of their algorithm, to the extent that said speech is different from the speech of the underlying content. (A simple, if absurd, example of

Compilers are some of the largest, most complex pieces of software out there. It should be no surprise that they come with bugs as all other large, complex pieces of software do.

AIUI, all such results are because the FDA has given up since aduhelm and said "well, if it clears amyloid, that's as good as slowing Alzheimer's, right?" despite the actual results on Alzheimer's progression being

Too bad we've had like a half-dozen putative Alzheimer's drugs that clear amyloid beta that turn out to do nothing to slow or prevent Alzheimer's. Actually, I think even by 2016 we already had enough phase 3 drug failures tha

I must say, I do love how this comment has provoked such varying responses. My own observations about using AI to write code is that it changes my position from that of an author to a reviewer. And I find code review to be a much more exhau

I'd expect that probably less than 10% of my time is spent actually writing code, and not because of AI, but because enough of it is spent analyzing failures, reading documents, participating in meetings, putting together presentatio

That's only true when forwarding IPv4x -> IPv4. When you're going the reverse direction and you need to forward IPv4 -> IPv4x, well, still need a table then.

Recall for a minute that floating-point arithmetic is inherently inexact, and it is thus pretty rare that you query for equality using an == operator rather than a relative or absolute error check (both of which involve < or > against

It should be noted that because of the effect of the poles on the atmosphere (the atmosphere is intrinsically thinner near the poles), the surface pressure is even lower, so that it feels like about 11k feet in altitude rather than 9k feet
