toruonu writes "How do you keep track of what's in your datacenter, where it is, what it's connected to and what is it doing right now? I mean I have built a datacenter from scratch over the years and I have machines from Sun, IBM, HP, Supermicro. I have machines that are simple workernodes and machines that are heavy grade storage consolidation machines. Then there are tens of switches, some for interconnect, some for management and don't get me started on the UPSs etc. So how does one keep any kind of decent track of such a system as the current form of twiki pages with various tables just doesn't cut it anymore and I'm looking for a freeware solution that could actually show me a visual representation of the various nodes in the racks, their connections and dependencies. Just to give a simple example, if I'm going to disconnect UPS #3 right now and swap switch #5, which machines should I even consider taking offline?" (The best-looking such system I've seen was being used at OSCON at a display booth for the Open Source Lab, and I think it was home-grown. Anyone who can shed light on that system?)

J. Dzhugashvili writes "New SSDs just keep coming out from all corners of the market, and keeping track of all of them isn't the easiest job in the world. Good thing SSD roundups pop up every once in a while. This time, Western Digital's recently launched SiliconEdge Blue solid-state drive has been compared against new entrants from Corsair, Kingston, and Plextor. The newcomers faced off against not just each other, but also Intel's famous X25-M G2, WD's new VelociRaptor VR200M mechanical hard drive, and a plain-old WD Caviar Black 2TB thrown in for good measure. Who came out on top? Priced at about the same level, the WD and Plextor drives each seem to have deal-breaking performance weaknesses. The Kingston drive is more affordable than the rest, but it yielded poor IOMeter results. In the end, the winner appeared to be Corsair's Nova V128, which had similar all-around performance as Intel's 160GB X25-M G2 but with a slightly lower capacity and a more attractive price." Thanks to that summary, you might not need to wade through all 10 of the pages into which the linked article's been split.

An anonymous reader writes "Wondering where all that bloat comes from, causing even the classic 'Hello world' to weigh in at 11 KB? An MIT programmer decided to make a Linux C program so simple, she could explain every byte of the assembly. She found that gcc was including libc even when you don't ask for it. The blog shows how to compile a much simpler 'Hello world,' using no libraries at all. This takes me back to the days of programming bare-metal on DOS!"

longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."

There are some differences, such as direct action is not required, but the concept of guilt by association for not doing the right thing is still on the face of the bill."

joabj writes "While MySQL is the subject of much high-profile wrangling between the EU and Oracle (and the MySQL creator himself), the MySQL developers have been quietly moving the widely-used database software forward. The new beta version of MySQL, the first publicly available, features such improvements as near-asynchronous replication and more options for partitioning. A new release model has been enacted as well, bequeathing this version the title of 'MySQL Server 5.5.0-m2.' Downloads here."
