Suspect in UNC student’s slaying is charged

21-year-old man faces first-degree murder charge in Eve Carson’s death

HILLSBOROUGH, N.C. - Authorities have charged a suspect in the slaying of University of North Carolina student body president Eve Carson with first-degree murder.

Documents filed Wednesday named the defendant as 21-year-old Demario James Atwater, of Durham.

Chapel Hill police and District Attorney Jim Woodall gathered Wednesday afternoon in an Orange County courtroom for Atwater’s first appearance.

With his public defender at his side, a shackled Atwater whispered, “Yes,” when asked if he understood the charged against him.

Woodall asked that Atwater’s next appearance be set for March 24.

The 22-year-old Carson was found last Wednesday lying on a street about a mile from campus. The biology and political science major from Athens, Ga., had been shot several times, including once in the right temple.

Her body was positively identified the next day, leaving to a massive outpouring of grief at North Carolina. Thousands gathered that day at two campus memorial services, and a third is planned for next week at the school’s basketball arena.

Carson was in a four-year leadership development program for undergraduates, taught science at Chapel Hill elementary schools and spent summers volunteering in such places as Ecuador, Egypt and Ghana.

The Board of Trustees at the University of North Carolina had offered a $25,000 reward for information leading to an arrest in her death, and police received hundreds of tips after the first two photos were released over the weekend.

No. 1 North Carolina 76, No. 6 Duke 68

unc.jpgNo. 1 North Carolina 76, No. 6 Duke 68: North Carolina Pulls Away From Duke:
North Carolina beat Duke in a finish that will no doubt be added to the list of highlight-reel games that have marked the series.

“Tyler Hansbrough’s layup with just over two minutes to go broke a 68-68 tie and Ty Lawson added a pair of free throws and a crucial steal as North Carolina (29-2) staved off a comeback by Duke (26-4) and held on for the victory. Lawson missed on his layup, but the ball was tipped in by Danny Green with under a minute to go for a decisive 6-point advantage. North Carolina scored 10 consecutive points to overcome a 2-point deficit in the final minutes.”

“The teams had come in with identical 13-2 record in the A.C.C., the fifth time in this long series that the title had come down to the final game of the season. But that was not all that weighed on the Tar Heels. This had been an emotional week in Chapel Hill, 10 miles down the road from Duke. And for once, the two teams set aside their rivalry long enough to stand together for a moment of silence to honor Eve Carson, the North Carolina student body president who was found shot to death near the campus early Wednesday morning.”

“The Tar Heels, wearing an ‘EVE‘ patch on the shoulders of their jerseys, proceeded to outplay Duke in a first half that would have been a runaway for North Carolina if not for Blue Devils point guard Greg Paulus. Green scored 14 points off the bench to pace the Tar Heels as they pulled away for a 42-31 lead in the opening half.”

Obama Actually Won Texas

Saturday, March 8th, 2008

NPR: Texas Two-Step Leaving Dems Flat-Footed:

“NPR’s Wade Goodwyn and Robert Siegel report that Clinton’s primary win means she snapped up 65 delegates to Obama’s 61. Not a big difference, but a difference nonetheless. But if the numbers in the caucus vote hold up, then Obama will win 37 more pledged delegates to Clinton’s 30. So Obama would have 98 delegates and Clinton 95 and he would leave Texas with three more delegates that Clinton.”

Mac Pro RAID Card not all that ‘Pro’

Friday, March 7th, 2008

Does RAID 0+1 instead of RAID 10. Really? Seriously?

btoimage_raid_macpro.gif I was contemplating ordering one of these with a Mac Pro because I wanted to use it in RAID 10. RAID 10 is a stripe (RAID 0) across two or more mirrored pairs (RAID 1). Conversely, RAID 0+1 is a mirror across two or more striped pairs. But as the manual clearly states, it doesn’t do RAID 10. It does RAID 0+1, and that’s not so good.
 
There are dramatic differences between these two configurations:

  • Chances of array failure:

    “Mathematically, the difference is that the chance of system failure with two drive failures in a RAID 0+1 system with two sets of drives is (n/2)/(n - 1) where n is the total number of drives in the system. The chance of system failure in a RAID 1+0 system with two drives per mirror is 1/(n - 1). So, using the 8 drive systems shown in the diagrams, the chance that losing a second drive would bring down the RAID system is 4/7 with a RAID 0+1 system and 1/7 with a RAID 1+0 system.”

  • Performance in degraded state:

    Another difference between the two RAID configurations is performance when the system is in a degraded state, i.e. after it has lost one or more drives but has not lost the right combination of drives to completely fail. In a RAID 0+1 configuration, the loss of any drive in a set causes the failure of that entire set and the set is removed from the RAID system. Generally (in the two set case) this means you are left with a RAID 0 system made up of the remaining set of disks. This probably slightly improves write performance and slightly degrades read performance (but that’s just a WAG, I haven’t done any testing). In a RAID 1+0 system, you would see the same effect on each mirror that loses a drive, but not the whole system. In other words, a RAID 1+0 configuration will tend to show similar, but less dramatic, changes in performance when in a degraded mode than RAID 0+1.

  • Recovery once a disk is replaced:

    RAID 1+0 only has to re-mirror one drive, whereas RAID 0+1 has to re-mirror the entire failed set. So RAID 1+0 will recover significantly faster.

Given these pretty significant failings of RAID 0+1 as compared to RAID 10, it’s a pretty good question as to why Apple would choose the much poorer option for its ‘Pro’ RAID card, for which it charges $720. I’m just really left scratching my head.

Shame on you Apple, shame!
