Paul E. Loeb asks: "I am wondering if there are any solutions out there that will allow the use of an 8x AGP bus with dual processing support. I prefer AMD Athlon MP, but Xeon would be fine as well. I am looking to build a high-end graphics and video editing system, and I don't want to submit to a single Intel or AMD processor. I do however wish to use a Radeon 9700 or GeForce FX, but that would be pretty pointless at a 4x bus. Thank you in advance for all of your advice."

degauss asks: "I am looking into various authentication schemes form my home machine, and one that I thought would be interesting would to be having a dummy login screen up with a user/pass prompt, but instead of entering a user/pass, you click at certain points on the screen in certain rytmhmic patterns (all of this is of course unknown to any unauthorized users, who will pound at the password for years). I was wondering if there it any such software or interface currently being developed, as it provides an interesting [semi-]biometric security solution without dumping a ton of cash on new hardware."

Fred Nowicki asks: "If you have ever used the P2P client Direct Connect (or DC++) to find media on the Internet, you know that the best hubs have ridiculous sharing requirements, i.e., over 100GB. It isn't too difficult to amass a collection of 100GB of illegal movies and MP3s with all the crap that's out there, but I'd like to play it straight: I want to collect 150GB of pure legal stuff. So here's my million dollar question: What is the best and fastest way for me achieve this? I want to offer interesting, neat stuff (movies, music, programs, etc.), not just Linux distros, mind you. One thing I've found so far is a mirror of the Prelinger Archives on archive.org, which offers over 37GB of wacky, interesting stuff on divx format (in MPEG-2, it's over 350GB, but that seems like cheating if I take that route). One downside of this site is that it's not a very fast connection (about 50KB/sec through their FTP via my cable modem -- I'd like a throughput of at least 100KB/sec). I've considered mirroring the Gutenberg project, but there are all sorts of redistribution issues with a bunch of their files, and I don't want to go through all that hassle. Come on, Slashdot. Give me some URLs!"

2nesser asks: "How do you define the term 'Software Engineering'? Some see it as the implementation of the theoretical world of Computer Science, but isn't there more to it than that? Social responsibility, documentation, a program that works under precise, known conditions? Can you compare Software Engineering to other disciplines? What sets a 'Software Engineer' apart from the rest of the crowd?"

Maxwell'sSilverLART asks: "I work for a University's Aviation Department. For several years now, we've run a streaming audio server to rebroadcast air traffic control communications over the web as an educational service to our students. This job had been handled by Winamp + SHOUTcast. We've just added a second channel to the system (we're now rebroadcasting approach control, in addition to the local tower), which means I need to find a way to get a second live audio stream into the system (signal comes from radio receivers tuned to the appropriate frequency), encoded (we're using 8-bit, 22kHz mono MP3, which is more than adequate given the source), and broadcast. Has anybody done this before? Surely I'm not the first to want to encode multiple live streams. How did you do it, and what were the pros/cons? Does anybody know of a good hardware device at a reasonable price (I'd need to sell my boss on two of them)? Ideas are always welcome."

Jason Weill asks: "After finishing up school, I'm transitioning away from my school-run IMAP e-mail account. During my time, I managed to save thousands of messages in dozens of subfolders in my 'Inbox' hierarchy. Pine lets me save an entire folder to a file easily. Mozilla creates a folder tree when I drag 'Inbox' into a local repository, but none of the messages in the subfolders are downloaded. Opera M2 assimilates all those messages into my collection, but it flattens them all into one giant mess. Are there any scripts or programs that can easily export an entire folder tree to files or import it into a local repository for an e-mail program?"

Caoch93 asks: "I recently read the Mono project's rationale and have found it compelling in the way it shows the Mono project as being the result of engineering concerns rather than concerns of siding with Microsoft. One thing that it has strongly bolstered in me is my belief that runtimes which interpret intermediary languages are going to play an increasingly important role in programming in the years to come, and it makes me wonder- should the open source community consider developing its own runtime (ala JVM or CLI) which would thus be totally open to the public? Currently, it seems like the options for a runtime are the JVM, which is still dominated by Sun with respect to its design future, and CLI, which is an ECMA standard but is critical to the Microsoft .NET platform. It would seem to me that having an open source runtime (and languages that compile to it) could be critical to moving with the times, and the freedom from proprietary influences would seem to be important to keeping such a system truly in the interest of its programmers. I don't know...is CLI already achieving this? I an ECMA standard enough, or is an ECMA standard really just codification of proprietary interests. If so, should the open source community consider its own itermediary language runtime...and what would be proper goals for such a project?"

dbright asks: "I am currently planning my upcoming honeymoon, and I was wondering if I should try getting my tickets, and/or making travel arrangements online using one of the many available retailers (cheaptickets.com, priceline.com, etc...). I wanted to ask Slashdot readers about experiences with any of these companies, and their thoughts on making arrangements online."

AlphaSys asks: "I live in a small apartment community in the Southeast US. Broadband offerings are great in the area (both xDSL and cable). But the management company for the complex has their own 'cable' system in place by which they distribute programming from their satellite system to the residents. The rental agreement forbids anyone from getting cable service from any other provider (except DirecTV, etc.), which also negates our getting cable internet from anywhere, limiting us only to DSL. Here's where I'm going with this: is there any way the front office folk could get broadband service (T1 or fractional) which they could (via a router and multiplexer) then send down the wire with the regular TV signal like cable companies do? I work in networking but have no knowledge of how cable companies roll the two signals together or how you split it out at the customer end -- I just do Cat5/e/6 and fiber but I want to know if these guys can use their existing wire for this. I've searched Slashdot and googled my eyes out but I really can't find any pertinent information on how something like this is done. Does anyone have any information on how something like this is done?"

netdemonboberb asks: "I don't know where else we should turn, because no site will write articles on [this subject] and IBM is denying that their IBM 600 series laptops have flaky batteries. Rensselaer Polytechnic Institute distributed these laptops to freshman students in 1999 and almost everyone I knew in my class had this issue. Ralph Levien's page has suggested it appears to be an issue with the 'Smart Monitoring' circuitry. I'm writing this article to get the issue out in the open so IBM can no longer deny it. These batteries are expensive, and I have had to replace mine 4 times already. Can anyone who reads/maintains slashdot help or provide any advice on getting resolution for this?" I must say that from personal experience, I've wondered if this might be the case as well. I have an IBM Thinkpad 600e laptop and I've already gone through 2 batteries. The laptop is currently inactive as it must be tied to the wall if it is to be used. Has anyone else experienced shorter-than-average battery life using these laptops? Were you able to do anything to improve the battery life?

Tommydog asks: "Any techies out there? I'm living in a rural area and would like to know from anyone qualified, if I can hook up 2 DSL modems point to point, and connect to a neighbor's home network who is running Internet Sharing. We do have a dry pair (we can only get one pair) of TELCO wires between our houses, which are about 2 miles apart. Before investing in a couple of single pair modems (T-1's require 2 pair), I'd like to know if anyone has been able to make something like this work. It turns out that I'm just a bit too far for DSL, but this neighbor does have it and will share it if I can get a good connection going. So, anyone have 2 DSL modems working point to point, back to back? Are there any caveats or precautions? Thanks!"

Tiber asks: "I had the pleasure of locking down the servers for a large company against the Slapper/Sapphire worm over the weekend. It wasn't enjoyable, less so because I knew I'd have to face it again come Monday when all our users brought their business laptops in. Sure enough, Monday morning, all hell broke loose on our networks. It got me thinking, instead of routers 'dumb' routers, does someone make a network appliance that does worm scanning inside the packets and log attacks? Perhaps someone has a project they know of that does this?"

CyPlasm asks: "MSN Careers had this article posted the other day that asked about a "Lifetime Career in IT: Is It Possible?" Does the average Slashdot reader think they will retire (with a pension, benefits, etc) after a long and successful career in IT?"

Camp CAEN asks: "I work for a computer camp at the local university and I was wondering: how one goes about getting grants? We currently are funded by attendees but I thought it would be ideal to offer scholarships or assistance to those in need. Students who come to camp are middle school and high school students, we teach programming (C++, Java, DirectX), web technologies (HTML, PHP, MySQL), and other technology related topics (system administration, digital video production). The camp lasts two weeks and it can be quite pricey. I know there are plenty of people who would like to attend but can't afford it. Does anyone know of state (in Michigan) or Federal programs that give out money for technology instruction? Or any companies willing to donate equipment/software/books to our camp? Finally, are there any people in education or social work who have done grant writing before and have any good resources (either online or paper)? Anyone else have good ideas or suggestions? Thanks!"

[null] asks: "Has anyone experienced problems with HP DeskJet printers (mostly 600 series) or ScanJet 4100C due to the power supply going bad? I've just got back from a friend whose scanner is currently toast as the power supply decided to put out something other than the 30VDC/400mA/14W it is spec'd for. I'm extremely suspicious because I have a DeskJet 660Cse with the same power supply brick that was working fine up until a month ago when it would go from printing fine to printing several sheets of garbage out of any given print job. I checked it with my tester and saw it giving out 37.5VDC (25% over spec). This link from HP PartSurfer lists the HP products using this power supply and has a picture. This power supply usually featuers a model number of C2175A molded on it. My friend's supply was listed as made by Lucent and mine is by NMB, causing me to wonder if the design itself is possibly defective. Google is not being very helpful in finding people with similar problems, and we are talking about pretty old hardware here that people would probably throw out rather than bother trying to order parts for. HP also has recalls on power supplies for DeskJet 800/900 series and some PhotoSmart 1x00 series printers. How about it, anyone else had problems?"

ikeleib asks: "I'm in the process of developing a HVAC control system. The problem with most programmable thermostats and just about every other electronic devices is that they are hard to use. I've been trying to find a book on user interface design for electronic devices. All the books I've seen on interface design seem to focus on GUI's. Does anyone know of good books (or websites) on interface design for electronics? I'm talking about buttons and tiny screens, not web pages and dialog boxes. I've only been able to find one book (for $104)."

VirtualUK asks: "I was given a WiFi base station and PCMCIA card for my laptop as a Christmas present so that I could read slashdot...urm I mean work, in any room in the house. When I read the manual it stated lofty figures of being able to work up to hundreds of feet inside office environments, so I felt that it would be more than capable of being able to allow me to stay connected in my tiny house. It seems however that the WiFi gods are against me as I tap this posting in the next room to the WiFi base station, a mere 20-30 feet away, just regular so-thin-I-can-hear-an-ant-fart walls, no kryptonite, no lead cladding and yet still I struggle to get a constant connection. I've found that shifting the laptop to face different directions sometimes helps, but as should it be this hard at such short range? Is there anything I can do to make my WiFi work better in a house environment?"

groovemaneuver asks: "I've managed to get a working OpenLDAP directory running on my network. Linux, Windows, and Apple boxes are all happily authenticating. I have imported the 'apple.schema' file to the LDAP server from one of my Macs, but I cannot seem to find any info on the proper syntax for the various apple schema attributes. Anyone have any idea where one could find this? This is the one obstacle keeping my network from having a single source of authentication, and I'm sure this info would be useful to more than just myself. Thanks!"

Orome asks: "From the point of view of someone who wants to learn 3D Graphics programming, specifically for games, it is currently daunting to see the number of options available. Should I first learn OpenGL to understand the rudiments of 3D graphics programming, or should I try and understand the Direct3D API (which has more to offer but is less easier to understand)? With the DX9.0 SDK available, would it be advisable to jump to the next level and learn how to use the high level shading language? Since shading languages are supposed to be THE next thing in 3D programming would Cg be a better tool to learn since it is cross platform." OpenGL and DirectX are always options, but might there be something a little less daunting for those just starting out?

BoneFlower asks: "Due to early registrations scooping up most of the good electives at my school, I'm stuck with learning COBOL(required CS class at my school) and Visual Basic.NET (only useful CS elective left) at the same time. The only tips I've gotten from IRC are 'drop one' and 'Focus on COBOL only enough to pass, and put most of your effort on Visual Basic'. I'd prefer to learn both well, do any of you have any suggestions on how to do this? What aspects of each could I use to enhance the other, and what apparent similarities should I keep in mind as dangerous traps? I also have some C++ knowledge, up to basic classes and memory management, so any of that that I could use in the current classes would be useful as well."
