Comment RAID 5? (Score 3, Insightful) 158

They wanted performance and went *RAID 5*? That pretty much sums the entire approach up. Let's not optimise the application first, the database second, but instead hide the problem by throwing hardware at it. Then what we'll do is use a RAID configuration that hobbles the write performance of the arrays and lets not mention what happens to performance when we lose a disk (don't say it won't happen).

Sure, RAID 5 is the answer to somethings, but not when the question is database *PERFORMANCE*.

Also - latency is more important than IOP/s. I don't care how many IOP/s you can do, if you're latency is high, the performance won't be. Most garden variety storage engineers don't seem to grasp this concept.

Comment dBase / Clipper (Score 2, Interesting) 578

Wow Deja Vu.
I remember the xBase (dBase / Clipper etc) languages being touted as the programming solution for non programmers. Programmers would be out of jobs, everyone would be writing their own applications. My first programming job when I left University was writing business applications in Clipper.

Submission + - Ray tracing for gaming explored (pcper.com) 3

Vigile writes: "Ray tracing is still thought of as the 'holy grail' for real-time imagery but because of the intense amount of calculations required it has been plagued with long frame render times. This might soon change, at least according to an article from Daniel Pohl, a researcher at Intel. With upcoming many-core processors like Intel's Larrabee he believes that real-time ray tracing for games is much closer than originally thought thanks in large part to the efficiency it allows with spatial partitioning and reflections when compared to current rasterization techniques. Titles like Valve's Portal are analyzed to see how they could benefit from ray tracing technology and the article on PC Perspective concludes with the difficulties combing the two rendering techniques as well as a video of the technology in action."
