Agg writes "Well the slab gets poured on Wednesday so I thought I would sink 6 meters of copper pipe in the slab so that I can run my water loop through it when the house is finished. I hope to have water year round at about 16deg [about 61F]. No need for radiators or fans with chilled water coming straight out of the slab!"

KingofGnG writes "Disney has chosen the San Diego Comic-Con International to present its new sci-fi project: the sequel to Tron. The classic movie from 1982 dealt with video games, virtual reality and 3D graphics when none of those things were widely popular. The new movie has got an official title and synopsis now, and they've released the very first trailer from the movie (this time without silly censorship) together with some concept art and the teaser poster." No matter how silly the movie is, they'll at least get my money for sheer nostalgia.

After enjoying several years of popularity, music games seem to be drawing less and less interest from gamers lately. Guitar Hero and Rock Band titles have been conspicuously absent from a list of the 20 best-selling software titles in the past two months, and one report estimates that revenue from those games has dropped by almost half. Analyst Jesse Divnich suggests that there's no longer much room for dramatic improvements in game play, saying, "it would be erroneous to assume that any franchise or brand can grow unless it brings something new to the table. After a while, utility to the gamer will diminish and he/she will surely move on." Nevertheless, the companies are happy to continue to rely on DLC sales while working on new releases. Harmonix is showing off a trailer and a partial set list for The Beatles: Rock Band, and Neversoft has detailed a number of new features and tracks for Guitar Hero 5.
