An anonymous reader writes with this excerpt from Significant Bits about how the early level design in Super Mario Bros. 3 gradually introduced players to the game without needing something as blatant and obtrusive as a tutorial: "Super Mario Bros. 3 contains many obvious design lessons that are also present in other games, e.g., the gradual layering of complexity that allows players to master a specific mechanic. What surprised me during my playthrough, though, was how some of these lessons were completely optional. The game doesn't have any forced hand-holding, and it isn't afraid of the player simply exploring it at his own pace (even if it means circumventing chunks of the experience)."

coondoggie writes NASA is working on some difficult renovations to reinvigorate its 70-meter-wide 'Mars antenna.' The antenna, a key cog in NASA's Deep Space Network, needs about $1.25M worth of what NASA calls major, delicate surgery. The revamp calls for lifting the antenna — about 4 million kilograms of finely tuned scientific instruments — to a height of about 5 millimeters so workers can replace the steel runner, walls and supporting grout."

dogmatixpsych writes "I work in a neuroimaging laboratory. We mainly use OS X but we have computers running Linux and we have colleagues using Linux. Some of the work we do with Magnetic Resonance Images produces files that are upwards of 80GB. Due to HIPAA constraints, IT differences between departments, and the size of files we create, storage on local and portable media is the best option for transporting images between laboratories. What disk file system do Slashdot readers recommend for our external HDDs so that we can readily read and write to them using OS X and Linux? My default is to use HFS+ without journaling but I'm looking to see if there are better suggestions that are reliable, fast, and allow read/write access in OS X and Linux."

Rock, Paper, Shotgun reports that upcoming action MMOG APB: All Points Bulletin will use in-game audio advertisements as part of its business model. The number of ads you hear will be limited: "you'll only hear an ad when you go into a new zone, and that's only once every three hours." Nevertheless, some gamers are upset that these ads will be included on top of APB's already unusual payment plans. The game is set for release next Tuesday. Producer Jesse Knapp says of Realtime Worlds' goals for APB, "We looked at other online action games, and we saw things we felt could be better. Only 12 to 32 players in a match, bad connection due to peer-to-peer, dead cities, way too much time in lobbies, things like that. So what we set out to do was to make a game that has that online player vs. player action game experience in a large city with other players around, no lobbies, dynamic matchmaking, dedicated servers, great experience, and that's been one of the driving factors of APB from the very beginning." CVG recently previewed the game.

yukk writes "Mark Suppes, a web developer for Gucci, is working on his own personal fusion reactor. His work in a NYC warehouse using $35,000 of his own money and $4,000 raised on a website has made him the 38th independent researcher recognized as creating a working fusion reactor. How's that for a hobby?"

tlhIngan writes "The US Air Force, having purchased PS3s for supercomputing research, is now the latest victim of Sony's removal of the Install Other OS feature. It turns out that while their PS3s don't need the firmware update, it will be impossible to replace PS3s that fail. PS3s with the Other OS feature are no longer produced since the Slim was introduced, so replacements will have to come from the existing stock of used PS3s. However, as most gamers have probably updated their PS3s, that used stock is no longer suitable for the USAF's research. In addition, smaller educational clusters using PS3s will share the same fate — unable to replace machines that die in their clusters." In related news, Sony has been hit with two more lawsuits over this issue.

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."
