gerddie asks: "Lately, we have seen a lot of companies starting to move their graphics stuff from high end to low end linux workstations (e.g. Dreamworks). Of course one reason to do such thing is cut costs, and therefore, at our institute we are going to replace or aging SGI O2s with Linux workstations. I wonder if you have experience with such a transition - especially regarding the usability of such machines for (scientific) visualization? What is working well, and where did you encounter pitfalls?"

Dormous asks: "My wife and I are both night owls and avid readers, and usually one of us goes to bed before the other, hence the need for a small portable light source. We recently had a booklight, and somehow, my wife managed to shatter the light bulb all over the bed. Therefore, I want to find a booklight that uses an LED as the Light Source. Anybody got any ideas where I can find such a thing. I've already tried ThinkGeek."

theWrkncacnter asks: "I was recently giving some instructions over IRC to a long time QWERTY keyboard user who wanted to switch to the Dvorak layout, mostly because a good majority of the people in channel had made the switch and were all talking it up, myself included, about how our speeds had increased and how its much more comfortable. This made me think, why don't more people use the Dvorak layout? Searching around I found an older topic on the subject, but that didn't answer too many questions, as most people in the comment section seemed to think that Dvorak vs. QWERTY was a hardware issue, when it is really a matter simply changing the layout on your particular OS. I took the time to pry off and remap my powerbook keyboard's keys but I have no problem typing in Dvorak on a physically QWERTY mapped keyboard, and I know many others who don't have a problem doing so either. So given all of this, why don't more people switch? Is it that most people just can't be bothered to make the change, even when its more efficient and more comfortable?" Is it mostly due to the fact that most people learn to type first on QWERTY due to its popularity, and hence don't bother to learn anything else?

MBCook asks: "I've been thinking of buying a writable DVD drive, specifically the Sony DRX500LX, an external CD-RW and DVD+/-RW drive. I need a drive to be able to store files on and make DVDs. It needs to be external so that I can share it between my desktop and my laptop, and it needs Firewire. The external version of the Sony drive seems perfect. It's fast, has very good reviews, and supports BOTH the +RW and -RW formats.The thing that I'm not sure about is that it lacks Mt. Rainier support (known as CD-MRW). Should I worry about this?"

Who Man asks: "There are many options when buying a display today: Direct-View CRT, CRT-Based Rear Projection, CRT-Based Front Projection, Direct-View LCD, LCD-Based Rear Projection, LCD-based Front Projection, DLP-based Rear Projection, DLP-based Front Projection, Plasma, lcos-based front projection, and lcos-based rear projection. Did I leave anything out? Each of these seems to have a distinct trade-off, and it gets especially confusing when the display is intended for multiple purposes--watching analog 4:3 video, watching hi-def 16:9 video, watching DVDs (in several different aspect ratios), playing PC games, and playing console games. A particularly sticky area seems to be getting a display that handles analog and digital signals equally well. Seems that the newer digital displays are great at displaying hi-def signals but make an analog TV show look horrible. Is there a display that's adept at handling multiple inputs? Has anyone had specific experience, good or bad, with any particular displays? What about using an external processor with a digital display?"

krahd asks: "We, at the CS department of our University, in Uruguay, are evaluating different ways of securing the access to our floor. Until now we have used just a traditional door lock, but its's time to delpoy a new, more geeky solution. So, after reading this Ask Slashdot, I figured I'd pose this question as a follow-up. What would be the best way to do it? We've already evaluated biometric technologies like iris-scanning and fingerprint-scanning, and more traditional ways like intelligent cards but, what others possibilities exist, and which would you choose? Yes, price does matter."

spacemonkey asks: "I am a professional developer, but in my spare time I have been developing games for the Microsoft Smartphone platform. Included in this work is a port of gnuboy a GPL gameboy colour emulator. Where does the GPL stand on the question of codesigning applications where required? Basically gnuboy is available, with full source for smartphone, however there are a large number of users out there who are unable/unwilling to remove the certification requirements from their smartphone devices, so to allow for these users, I need to sign the code. To enter into the code signing program will cost me approximately £500. I am interested in signing the application to make it available to a wider audience, however since I am not running a charity I was wondering whether charging some nominal fee for the code signed version was compatible with the GPL or not. So users would have an option on a signed version for less than £5, or an unsigned version free, which will include the full source code. Am I allowed to charge for GPL software in this way, where the charge is to cover the packaging of the application into a signed form?"

An anonymous reader asks: "Thanks to Walmart, TigerDirect, and Gnu/Linux, I can get computers at about $200 now. Thanks to Matrox, I have several multi-head video cards. Thanks to a hacker's convention last year, I have a truckload of monitors that haven't been put to use yet. I've been out of the financial markets since 1996. I'm itching to get back in now, especially since conditions will be very favorable shortly. Since I've lost my shirt in the markets already (most investors/traders loose their shirts at least once before striking it rich, and my beating was especially instructive), I'm now ready for better returns. Gnu/Linux is well known to support multiple monitor setups. I've seen 4 monitor setups per box in some financial firms, and I recently read a story on the National Weather Service using 3 monitor setups on another OSDN channel. I've also used a Quotrek trading monitor in the past, for monitoring stocks and other financials in real-time. This was before I was a penguinista. Now that I know a bit about Linux systems, I'd like to know the following: What Gnu/Linux applications can I use to monitor and/or process stocks, options, bonds, financial news, and other related information via low cost Gnu/Linux computing solutions, broadband, and multi-head video cards? Free software only, please"

tjjuggle asks: "Why is so hard to do local communication on the internet? Suppose I want to find a group of random people to play soccer with tomorrow. Given that I live in a town of 50,000+ people, many of whom are online, there should be a way. For major metropolitan regions, Craigslist.org fills this gap, but it is no use to those of us who live outside of the San Francisco Bay Area. Has anyone developed a service like Craigslist which can be used throughout the country? I imagine a site that, given a zipcode, it could then tell you which users are signed up who live within 10-20miles of you. Does anyone know of other local communication mechanisms?" Even now, one of the best ways for local communications remains Instant Messaging, but you usually have to meet the person, first. Are there other community-oriented websites out there that can assist users in meeting other users who live nearby?

a-freeman asks: "Faced with the prospect of doing automated weekly backups for several servers with some 200 GB of files each, I have been looking for a remote backup solution. A couple of recent articles consider backup to hard drives, although I feel this still fails the 'separate snapshot in time' aspect of good backup policy, since with many of the solutions that I have seen, you will likely lose all your backups if your array gets corrupted. However, CD-Rs and DVDs are just too damn small. Can anyone recommend a remote backup service or interesting combination of hosting service + FTP/RSync/etc., or am I stuck buying a tape drive?"

Adam Weiss asks: "With Web Interfaces and GUIs being all the rage these days, it seems hard to find much about console application development. Web Interfaces and GUIs look pretty and impress people, but I've noticed that it's awfully hard to beat the speed of a well trained operator on a well designed console interface. Some of the HR folks at work use a console app to access employee records while others use a Windows GUI. The console folk can lookup and update three records in the time it takes the the GUI folk to clicky-clicky through one. So, are there any mature Open Source toolkits that would enable rapid development of console applications. Sure, there's curses, but that's low level pain in the arse. I'm talking like something that is specifically designed for building database applications- kinda like an extensible version of Microsoft Access Forms for the green screen. Something that's pretty easy for the simple stuff, but lets you break out and get complicated if you need to. (unlike Access) I know there's gotta be plenty of obsolete commercial stuff that makes these kinds of projects easy. I just want to know if there are any Open Source alternatives that are somewhat modern and well maintained."

terradyn asks: "Recently, I've been looking for a cheap external storage subsystem solution. Aside from the fibre channel high end solutions out there (IBM FastT, HP EVA, etc.), I haven't been able to find much for the SOHO type market. My current best possibility is this. It provides the capacity and interface type I was looking for (8 bay, ATA6, 1394) but lacks features like RAID5 or NAS type abilities. Has anyone found a better solution with at least RAID5 in a similar or smaller form factor for use in the home (I need the space/speed/reliability for video work)?"

An anonymous reader asks: "I work for a medium-sized university (25K students), and have been asked to come up with ideas on how to reduce our exposure to the RIAA. Our head of IT gets 50 to 100 emails from the RIAA every week, complaining about IP addresses where P2P applications offer copyrighted songs for download. We don't want to firewall off P2P applications completely, we just want to get the RIAA off our backs. How do other university IT departments educate students to stop attracting the RIAA's attention? Thanks for any war stories you might be able to share !"
