It's about time that we had a thread devoted to cool science news. I'm always seeing interesting articles about various science related news and I know I'm not seeing half of what's out there. Let's kick it off with this tough bug:

it focuses on randomizing bits of data known as “undefined semantics.” Undefined semantics are nooks and crannies of the computing architecture—for example the location, format, and content of program code. They’re part of a processor’s most basic machinery, and legitimate programmers don’t generally interact with them. But hackers can reverse-engineer them to uncover vulnerabilities.


The MORPHEUS chip protects undefined semantics through what Austin calls “encryption and churn.” Encryption randomizes the important undefined semantics that hackers need to launch a successful attack, while churn re-randomizes them while the system is running. This puts attackers in a race against the clock to discover the information that they need. Austin said that the churn rate is normally kept low to keep system performance high. But when a would-be hacker exercises an undefined semantic in an attempted attack, the churn rate spikes, stopping attackers in their tracks.

Super human abilities


I know we have a few baseball fans here. When Williams was drafted into the military,a physical revealed he had 20/10 vision. Humans with that gift can identify faces a 1/2 a mile away. He could also see the seams of a baseball thrown at 90mph.

I'm sure you meant Tony Gywnn, but yes,he had the gift as well.

.

One of the greatest stories I've read about Williams was from an old field and stream magazine. Williams was an avid fishermman after he retired. He was being interviewed at a local HS baseball park. The reporter asked him could you really see the seams. Williams said yes,and I'll show you. Williams was 60 years old at the time. The Hs had a highly recruited pitcher with a 90 mph fastball. Williams took two pitches. The first was a warning track fly to CF. The reporter said I was just glad he could still hit. The 2nd was a line drive HR over the RF fence. Williams said the first one was 1/4 in below the seam. The Hr. was directly on the seam. When both balls were collected,Williams was correct.

Another story I remmeber hearing was that in the late 40's he was being heckled by an opposing fan next to the 3rd base dugout. Williams started hammering line drives at him and the heckling stopped. :)

Man, that's like a rough draft of a stay-of-execution for all humanity.

Yes I meant Tony. No idea why I typed Ted. After Ricky Henderson Tony was my favorite player in the late 80's and 90's.
