Tom asks: "The time has come for me to upgrade the audio on my computer. This was last discussed, here.My specific area of interest, is the sound card, in its various embodiments. Two cards that I am considering are Creative Labs' Audigy2, and M-Audio's Revolution 7.1. These companies also have USB counterparts to their products - the Extigy and the Sonica Theatre - and I can't decide if USB's portability and other various advantages justify its shortcomings. Experiences, anyone?"

frink_exp asks: "Cleaning mouse balls (and the rollers they contact) has been the source of many a pun and the subject of countless junk e-mail messages. As more optical mice replace their mechanical kin, such hygiene is becoming unnecessary. However, the mouse wheel is nearly as common as the mouse itself and human hands are grubby, sweaty, oily appendages. Invariably, a nice coating of gunk envelops the wheel. Sometimes it's just unsightly, but at it's worst, it'll sap the rubber wheel of all its grip making it difficult to scroll. Cleaning the wheel can be awkward as it tends to spin and unlike mouse balls, it doesn't just pop out (rehashing of the balls joke intended). The best method I've found is scraping sideways, parallel to the wheel's axis of rotation, slowly working my way around the whole wheel. This is tedious and annoying. Is this a common affliction? What is a better, easier way to clean the mouse wheel? Solvents? A wheel brush? Fire?"

An anonymous reader asks: "I have recently (as in today ) acquired a 250GB external HD with both USB2 and Firewire ports, with an eye to using it to carry around all my stuff (my humungous e-mail archive, ISO images of whetever distro I'm running, music and work files - I do a lot of database work, so I often need to move 40GB+ database dumps). The thing is, In order to make proper use of it I have to be able to mount and write to it on all three platforms I use: Windows (easy, it comes formatted as FAT32), Linux (trivial mount syntax) and Mac OS X (it just works as is, since it also supports FAT32). However, I'd like to get rid of FAT32." What filesystems, aside from the FAT varieties, have decent support across the major operating systems?

shroudedmoon asks: "I'm looking for a solution to create a printable floor plan (line drawing) and 3D walkthrough of a house that I'm preparing to build. I've got a rough design on paper that I want to tweak on the screen, and then show to my architect/father so that he can create the finished and buildable blueprints. I've know there are consumer packages out there like 3D Home Architect from Broderbund, but I've heard that the graphics and navigation are less than spectacular. I also recall a Slashdot article, a couple of years ago, about the possibility of using the editor of one of the 3D shooters (Doom, maybe?) as an architectural tool, but I can't seem to locate it. Just curious if anyone out there has had any experience with anything similar, or which of the current 3D Shooters might have the best editor for something like this."

KReilly asks: "As the school year starts back up for me, I have been looking for a volunteer program I could work in. This year I have been considering creating my own non-profit organization, but I still lack a clear picture of what I hope to accomplish. I have read about communities wiring classrooms for the internet in California, and repairing computers donated by businesses for schools. I would like to do this, but find many schools and libraries would deny this donation since its maintenance would be too big of an investment for them and they do not want to experiment with Open Source alternatives that would lower the PC repair cost. So my question to you is how do you, as a tech, give back to society and aid in social programs? And, any information/advice you wanted to share on my original idea would be much appreciated."

Adam Ernst asks: "I'm trying to build a low-end tablet PC type device for giving tests to students in a classroom. The touch screen TFT wasn't hard to get and the WiFi shouldn't be too hard either, but the most difficult part has been finding a motherboard! I tried Via's Mini-ITX, but it was too tall at about 1.5 inches. The motherboard needs to be just three quarters of an inch tall; the length and width can't exceed 8 inches each, but the smaller the better. No fans allowed--this has to be silent. The -only- requirements feature-wise are that it is able to connect to a TFT-LCD, has either USB, CompactFlash, or PCMCIA for WiFi, and has enough power to run Red Hat or SuSE (the only Linuxes my IDE supports). No ports, no ethernet, not even sound. Preferably it would take straight power (just one wire in and one out, at some set voltage) so I don't have to mess with power circuits. Of course, the most important factor of all is cost, since it's for schools (preferably less than $100 in small quantities ~90 units)."

justin asks: "Earlier this week, I went into work I was met at my desk by upper management; they wanted to meet with me. I was not sure as to why but when we got into the office, they set a pile of paperwork in front of me, opened it up to a certain page and asked me what it was. The paperwork was a series of (gimpy) logs showing an internal IP address doing a combination of scanning, and then what looked like hacking, of various boxes on the internet (of these there was the US Treasury among other US Government Organizations). The internal IP address was that of the one I am normally (read: not always) assigned by DHCP. I told them I had no idea what this was, that I didn't do it and that I think I would remember hacking into the US Treasury. I was a contracted employee, so I don't think I have any recourse, I was just left high and dry accused of something that I did not do, and their basic sentiment was 'we will investigate this, do you want us to call you and give you your job back if you are innocent?', This seems rather silly to me since you'd think such things would be investigated, before they would decide to fire me. I'm looking to find out who else has been in this situation and how they dealt with it."

Huxley_Dunsany asks: "Yesterday, while attending the (super-duper cool and fun) Classic Game Expo here in Las Vegas, I was lucky enough to trade some old game stuff (Intelivision II, ZX-Spectrum, some Neo-Geo Pocket games) for a really neato black Sony Playstation 'Net Yaroze' edition. For those that don't know what I'm talking about, back in '97, Sony came out with a (very) limited edition of the plain old Playstation. Back in the day, the 'Yaroze' PSX ('Yaroze' supposedly means 'Lets do it together') came with some special cables and software for PC/Mac, and, given enough time and effort and programming talent, you too could create your own Playstation games! Unfortunately, the Yaroze I got yesterday came with nothing but the main CPU - no software, and none of the special PSX-to-PC/Mac serial cables. This morning, I hooked it up and hit the power button, and it fired right up with no problems! So, I'm just wondering if any of you have ever used this seemingly rare dev system, and if you could pass along any good ideas or advice. It seems that Sony has long since discontinued this program (and then recently started it again with the PS2 Linux kit), so I'm not sure where to turn for help if I actually wanted to use this thing to make some games, let alone finding/creating the cables and software."

LilJC asks: "I work at a company that does service work nationwide for a major chain. Our vendor requires a signature for every visit to every store. We have been running thus far from ICR on faxes and linking to the faxed signature image on our web site, but are having numerous problems trying to depend on a thousand+ faxes a month coming through perfectly. We are looking for an economical alternative that would allow a contractor in the field to get a signature and transmit it to us in an system I can idiot-proof. Something along the lines of the UPS guy's digital clipboard, but without the pricetag of a Telxon. Brainstorming myself, I wonder if there must be a cheap PDA/modem combo or the like that would allow a contractor to enter required visit information, get a store signature, go home, plug it into their phone line (without needing a computer), and hit send. I can code and am not afraid of doing some custom work for an app on a handheld. Does the Slashdot community know of any projects along these lines, or have ideas about a wise choice for hardware to homegrow the software on?"

garyebickford asks: "I recently learned that a company I co-founded a long time ago has degenerated to the point where the present principals have sold off most of the equipment and have moved 'operations' into their houses. Though the founding concept is almost two decades old, they still believe that they'll be able to pull something out of a hat. I'm pretty sure the two remaining true believers haven't been paid for several years, and have been working outside to support themselves. The company hasn't sold anything for years as far as I know, but they have kept it running through an amazing series of trials and tribulations including some of the most amazing legal shenanigans I've ever heard of. The stock was delisted a long time ago and is now valued at about $0.001. Of course, who knows? Maybe it will recover. It's happened before. I'm sure we all know of many others, like snakebit projects that have migrated from company to company, and 'entrepreneurs' who could raise money over and over but never quite get a company going, and of course, really cool technology that just never seemed to come out of development, or was almost done when the money ran out?So Slashdot, fess up - do you have a 'company in a box' downstairs? What kind of earth-shaking, irrelevant or worthless technology is sitting under your stairs? More interestingly, why are you, or they, still committed to the business?"
