  1. High Performance Diskless Linux At AX-Div, LLNL

    Lee Busby writes "As a co-author, I am biased, but I think that our recent paper describing a diskless Linux deployment at Lawrence Livermore National Lab (PDF)may be of general interest. It's a little different than most diskless systems -- simpler, and designed to be high performance."

  2. Online Scientific Information Portals?

    Knacklappen asks: "On August 5th, vascoda, Germany's new central access point for comprehensive scientific information, goes online. It will incorporate 23 virtual libraries and 4 scientific information networks, and offer these information for free. For the paying customer, there will also be access to electronic journals. What freely accessible scientific information portals do you use? I usually turn to the following when searching for articles: arxiv.org, AVEL, CiteSeer, dissonline.de, DOE Information Bridge, DSpace, ETD, NDLTD, OAIster, OPUS, TheO. Are there any others that you can recommend?"

  3. Increasing Fuel Mileage With Hydrogen?

    cr0sh asks: "I was recently looking into the costs and availabilty associated with small, hydrogen fuel cells (results: they are still expensive), when I came across this site about the Hydrogen-Boost [Warning: Pop-ups]. Looking at this site, it seemed like just another in the long line of scamming 'get more mileage/power' engine products out there, but it intrigued me enough to continue looking into it. I eventually came upon another site on hydrogen experiments. A little more searching revealed this one about constructing your own Hydro-Boost device, which goes into detail about how you would build such a system. None of these sites answered the big questions, however: 'does it work?', and 'if so, how well?'. I also wanted something a little more authoritative. So, back to digging...which came up with this paper from OSTI [PDF]. The very first line of the abstract of this paper reads 'It is well known that hydrogen addition to spark-ignited (SI) engines can reduce exhaust emissions and increase efficiency.' This paper seems to advance the notion that such a system like the 'Hydrogen Boost' system may actually work. Does Slashdot think such a system would work? If so, how it could be improved, especially given today's rapidly rising gasoline prices, here in America?"

    "On the experiments site, via the link to 'Hydrogen Experiments Part 2', the author references the first site. He ultimately decides to 'home-brew' his own system instead, and gives enough detail for anybody to do so. I was hoping the author had more details on the effects caused by dumping hydrogen into his engine, but that doesn't appear to be.

    A notable observation on the Hydro Boost Device is that instead of using a stainless steel mesh as the other guy uses (which would seem to be a superior material to use, though difficult to find), this design uses galvanized steel bolts for the electrodes, making it something that can be built from materials found at a local building materials warehouse."

  4. Publishers' Attack Free Government Sites

    An anonymous reader writes "After succeding in getting the DOE's PubScience shutdown the Software and Information Industry Association and publishers' are now targeting more. If the trend continues local tax dollars will increasingly be spent to buy access to information the federal government used to provide."
