Comment Re:In Linux drivers, Intel is still king. (Score 2) 161

While AMD is releasing documentation, Intel is releasing actual open source drivers. And now that Intel's graphics hardware is no longer a complete joke, Intel is becoming a real alternative for some users.

AMD is still better than NVIDIA, which doesn't release documentation.

For a concrete example, the RSA public key includes a number n, which is the sum of two secret primes p and q. The encryption is broken if an attacker can derive p and q from n by factorization. ( http://en.wikipedia.org/wiki/RSA_(algorithm)#Operation )

if you could factorize an RSA public key 48% of the time then it would be a pretty big deal, since it would render RSA completely obsolete.

> That would break the main goal of NTP, which is to provide high accuracy time to computers. Many systems, such as telescope control systems, financial trading software etc, depend on NTP to regulate the computer clock at the millisecond or microsecond level, and this accuracy would be lost during a google-style smearing operation.

Anybody who really cares about reliable time, such as telescopes, should use TAI and not UTC (and I think they do).

To me it is incomprehensible why Unix uses UTC instead of TAI for the hardware clock - TAI is the obviously correct choice.

> Why not bundle them and apply them every 10 or 20 years?

The problem we have here is that leap seconds are rare. Things that are common are tested for, and quickly found if broken. Having something which only happens every 20 years is a recipee for disaster every 20 years.

My view is that NTP is at fault, because the 61th second is a brittle way to handle it. NTP should use the same method as google for smearing the leap second out over fx an hour: http://googleblog.blogspot.dk/2011/09/time-technology-and-leaping-seconds.html

I have needed it to restore some old inherited laptops with Windows. And once for my home computer, which I assembled from scratch, reusing a Windows key from a laptop, so no OEM to call.

Last time I called them (in Denmark), asking for a link to an iso, their supporter told me I couldn't get one. He suggested I download one off the pirate bay.

Comment Where will I then get a Windows ISO (Score 4, Interesting) 148

Computers nowadays don't come with a Windows CD. So if a virus messes up my computer, what am I to do?

I have always downloaded a Windows ISO off the Pirate Bay, which I do with an entirely clean conscience, since I own a valid Windows Key, which Microsoft also checks when I actually install windows. Websites like the Pirate Bay is what makes it actually a tiny bit user-friendly to use Windows, in spite of Microsoft.
