Submission + - Visualizing Complex Data Sets (omninerd.com)

markmcb writes: "My company recently began using SAP as its ERP system and as we move into our second year with the software, there is still a great deal of focus on cleaning up the "master data" that ultimately drives everything the system does. The issue we face is that the master data set is gigantic and not easy to wrap one's mind around. As powerful as SAP is, I find it does little to aid with useful visualization of data. I recently employed a custom solution using Ruby and Graphviz to help build graphs of master data flow from manual extracts, but I'm wondering what other people are doing to get similar results. Have you found good out-of-the-box solutions in things like data warehouses, or is this just one of those situations where customization has to fill a gap?"

Submission + - Balancing Performance and Convention (omninerd.com)

markmcb writes: "My development team was recently pondering over a finding a practical solution to the problem that's haunted anyone who's ever used a framework: convention vs. customization. We specifically use Rails, but like most frameworks, it's great for 95% of our situations, but it's creating big bottlenecks for the other 5%. Our biggest worry isn't necessarily that we don't know how to customize, but rather that we won't have the resources to maintain whatever customize code going forward, i.e., it's quite simple to update Rails as it matures versus the alternative. What have been your experiences with this problem? Have you found any best practices to avoid digging custom holes that you can't climb out of?"
It's funny.  Laugh.

Submission + - A Snarky Halloween History: Monsters Edition (omninerd.com)

uriah923 writes: "Nick Dilmore has published the second edition in his Snarky Halloween History series, featured on Slashdot last year. This time around, he concentrates on movie monsters: vampires, werewolves and zombies. From the article, "[D]id you know the movie monsters we've all to come to know and love (in a platonic way, of course) have colorful histories stretching back to the earliest civilizations? What, you didn't think some Hollywood hack actually had enough imagination to invent vampires, werewolves, and zombies, did you? Silly, silly non-monster-trivia knowing person.""

The First Evolving Hardware? 148

Masq666 writes "A Norwegian team has made the first piece of hardware that uses evolution to change its design at runtime to solve the problem at hand in the most effective way. By turning on and off its 'genes' it can change the way it works, and it can go through 20,000 - 30,000 generations in just a few seconds. That same number of generations took humans 800,000 - 900,000 years." The University of Oslo press release linked from the article came out a few days ago; the researchers published a paper (PDF) that seems to be on this same technology at a conference last summer.

Submission + - Top 12 Operating Systems Vulnerability Summary

markmcb writes: "Have you ever wondered how vulnerable your computer is from the first bit you write to the hard drive all the way until you have a fully patched system? If so, Matthew Vea has posted a concise summary of security strengths and shortcomings for twelve of the major operating systems of 2006/2007. In his summary, Matt tests each OS with widely available tools like nmap and Nessus, and notes responses at install, pre-patch, and post-patch times for each system. After the tedious job is done, he produces results that will make both the Apple and Windows communities cringe with regards to security. From the article, 'As far as "straight-out-of-box" conditions go, both Microsoft's Windows and Apple's OS X are ripe with remotely accessible vulnerabilities. ... The UNIX and Linux variants present a much more robust exterior to the outside. Even when the pre-configured server binaries are enabled, each [Linux] system generally maintained its integrity against remote attacks.'"

Semi-Identical Twins Discovered 224

daftna writes in with a story from Nature about a pair of twins who are neither identical nor fraternal: they are semi-identical. Researchers discovered twins who share all of their mother's DNA but only half of their father's. Both children are chimeras — their cells are not genetically uniform, but include a mix of genes from two separate sperm cells that fertilized a single egg. This is, apparently, not as rare as one might think; but the resulting fetus is rarely viable. This report marks the first known incidence of two half-identical twins resulting from a double fertilization.

Quantum Computer Demoed, Plays Sudoku 309

prostoalex writes "Canadian company D-Wave Systems is getting some technology press buzz after successfully demonstrating their quantum computer (discussed here earlier) that the company plans to rent out. Scientific American has a more technical description of how the quantum computer works, as well as possible areas of application: 'The quantum computer was given three problems to solve: searching for molecular structures that match a target molecule, creating a complicated seating plan, and filling in Sudoku puzzles.' Another attendee provides some videos from the demo." Anyone want to guess how long before "qubit" gets compressed to "quit" (as "bigit" became "bit" in the last century)?
