meriksen asks: "I found a very interesting paper which I am sure will stir up a hornets nest. Despite the growing success of the Open Source movement, most of the general public continues to feel that Open Source software is inaccessible to them. This paper discusses five fundamental problems with the current Open Source software development trend, explores why these issues are holding the movement back, and offers solutions that might help overcome these problems." What do you think of the issues given in this paper, and how do you think the Open Source community should address these issues?

nasteric asks: "I caught myself in the middle of a very interesting discussion last Friday over Krispy Kreme donuts and coffee. The discussion had to do with usability and security. Many of the Microsoft Administrators I work with argued the more user friendly Linux becomes, the more vulnerable it becomes. They claimed making Linux a friend of Joe User will require it to 'open itself up' and become more susceptible to attack. Needless to say, this became an endless debate between our Microsoft Administrators and our Linux/Unix Administrators that will undoubtedly continue into the morning. Therefore I pose this question to the Slashdot community. Will making Linux more user friendly result in it becoming less secure? Hopefully your expertise will help shed some light on (and bring to and end) our discussion." Does decent usability necessarily imply the presence of vulnerabilities? Macs seem to have this area down pretty well, with little in the way of vulnerabilities. Can Linux software follow the same route?

andrewa writes "Do any folks out there have recommendations on available gear for building a small, but extendable, rack-mounted system? As a developer of software for use in contact centers I want to put together a small development system that consists of at least three PCs to create a simulated environment to test my applications in. Why rack mounted? Well, I want to save space and only have the bare minimum systems (no need for multiple CD-ROMS, monitors, no sound-cards, just lots of memory and HD space). I also will add to this in the future, so don't want to limit myself to just a few pcs on the system. I've scouted around a bit, but didn't see too much. I'm in the UK at the moment, but will be moving to the U.S. in about 6 months, so power requirements (although I guess most equipment has switchable voltages) is a consideration."

einstein writes "I live out in the middle of nowhere, and I lose power at the drop of a hat. My house is right next to the Susquehanna river, and all the kinetic energy going past my house makes just want to go off grid. Most homebuilt hydro power is lower volume/high speed. What would be a good, unobtrusive way to generate electricity from a high volume/low speed body of water? I'm between two large hydro dams, so the water level is fairly constant, but does tend to fluctuate 4-6ft in the winter due to ice floes and melting snow. I think maybe a miniature version of one of the recent submerged tidal generators might work... Does anyone have some suggestions on how I might go about this project?" More than a few people have done this before.

A user writes "CNN is reporting that AOL is giving away a spammer's Porsche. As part of a settlement with a spammer, AOL took the spammer's Porsche Boxster S, and they're running a sweepstakes (already ended) to give the car away."

theodp writes "Over the next week, taxpayers in 19 states will be confronting new sections on state returns that ask them to fork over unpaid sales taxes for items purchased out of state, including Internet transactions. A NY Daily News editorial characterized the addition of use tax to state returns as a rip-off and advised taxpayers to fill in a zero on the line, although an accountant suggests doing so may even be worse than just leaving it blank and put you on the line for tax fraud."
