brace asks: "With the proliferation of online music sales, more and more companies are jumping onto the bandwagon and trying to sell you downloadable music. Some of them do a good job, some of them are just bad at it. The question I have for Slashdot readers is essentially 'What would the perfect online music store offer you?' Should it have OGG and FLAC tracks, as well as MP3? Would you rather pay per-song or per-month? Would you want the option to purchase hard-copy as well (like the actual album, or even band merchandise)? Should the song samples be 30 second downloads or full-song streams fed on-demand? Is a radio station important for an online music store?"

Dishes of Ryan writes "I fell in love with the idea of an LCD monitor, so I ended up buying a nice, shiny Dell 2001FP. However, nowhere, and I mean *nowhere* did I read about LCDs having an input lag on them. For instance, if I scoot the mouse across the screen, there is a noticeable delay between when I move the mouse and when the cursor moves. To prove it to people, made a video showing exactly what I mean. You can almost forget being king of the hill on twitch FPS games like Unreal Tournament. Are there any other Slashdotters out there that are as annoyed as I am? What did you do?"

ATMosby asks: "I was asked today to look into how a single sign on can be implemented. Now part of the constraint is that is must be very cheap (and by that the powers that be really mean free!) Of course there are all sorts of legacy applications that are 'required' to work with this, ranging from java applications to ancient pc programs. I've poked around a bit and found some pointers to commercial software that seems to be able to due bits and pieces of the job, but nothing that will do everything and anything that might be thrown at it. Before I just go and tell folks "No bloody way!" does anyone have words of advice to offer on the topic? Stories of successful or wildly unsuccessful attempts? Commercial or otherwise?"

An anonymous reader asks: "I'm about to install a sprinkler system for my lawn. There are lots of timers and computers out there to automate the watering of your lawn. However, before I go out and buy something, I wanted to know if there are any interesting open source projects for watering lawns. I've heard about smart sprinklers that get weather from the internet/satellite and water accordingly. What have other Slashdot readers done?"

occamboy asks: "I'd like to register a new domain, but I'm tired of getting tons of spam (most filtered, but some not) and snail mail whenever I register a new domain. In short, I'd like the domain, but I don't want to announce the details of its owner to the world. I was thinking of using GoDaddy's domain proxy, but the terms are scary: they reserve the right to change the agreement anytime, by posting the new terms on their site, and the buyer automatically agrees to the new terms. What's to prevent them from grabbing my domain name from me, or doing some other nefarious thing? So, is there any good way to anonymously acquire a domain? Should I just register with fake info, use a service ... or what?"

X43B asks: "I'm building a 'luggable' computer for numerical simulation work (very niche, I know). My goal is to have the best single precision floating point performance for under $1000. I have decided on a Shuttle XPC layout. I can build a AMD 3500+ for ~$80 less than a Prescott 3.4Ghz. I know the AMD is supposed to be a better 'general purpose' CPU however I found this comparison which says the Intels are better for floating point. Additionally, even though the AMD is somewhat cheaper, I have found the free Intel Linux FORTRAN compiler quicker than gfortran. So even if the AMD had similar performance for cross compiling, the Intel would be ~10% faster with the free compiler. Does anyone have any recommendations on AMD vs Intel for single precision floating point operations? If you recommend the AMD, what (cheap or free) compiler can be used that is comparable to the Intel?"

flyman asks: "I recently was 'downsized' from a company, and have had to really cut back on expenses. One of those cut-backs was to cancel my business class DSL with static IPs. I have since signed up for standard Cable Internet, which only has dynamic IPs. I know there are several DDNS providers out there, but which ones are good? Easy to use? Free or cheap? I still want to host some dev sites from home, if possible. Any advice would be appreciated."

An anonymous reader submits "We keep reading about cities dishing out free wireless; Philadelphia, San Francisco, Austin, TX, and many, many others. But how does one go about forming a group to get their city to go wireless? Looking around, there are a few articles out there, but most deal with selling it to businesses. I haven't been able to find a definitive guide to "Getting your city to go wireless". So I send my plea out to the Slashdot community - just how does one go about getting your city to go wireless?"

stephendl writes "I have been asked to give a computer based talk to a local primary school. It is part of an after school science club and I have a pretty free rein to talk about whatever I want for 10 minutes. The children will be aged 9 and 10 and will come from a range of backgrounds, there will be a parent of each child present too. My initial thoughts for the subject included the history of computers, the components in a computer and what computers are used for. Does the slashdot community have any suggestions, experience in this area or tips?"

Human Factors Guy writes "We've seen here before car manufacturers putting more and more technology into cars, but what are the cars of tomorrow going to look like? Driver monitoring through head and eye tracking (which Volvo is already implementing), Adaptive Cruise Control systems, maybe even pedestrian recognition systems. With cars becoming more like semi-intelligent robots every year, what do /. readers think will and won't make it?"

worm eater would like to know: "As the mainstream media is coming under closer scrutiny from the 'blogosphere,' and is having to actually respond to these journalists in pajamas, I thought I'd ask Slashdot: what are your favorite political blogs? Lately I've been reading Talking Points Memo, a liberal weblog by Joshua Micah Marshall, and a blog by Andrew Sullivan, a conservative writer. Where do you go when you want to see the mainstream media dissected and poked at?"

William George asks: "As of April 1st, 2004 it has been required that all cable companies in the United States be able to provide customers, upon request, with a High Definition set-top box with IEEE 1394 (FireWire) connectivity (e-CFR Part 76.640 Section 4 Subsection i). This was designed to allow easier connections between modern TVs, set-top boxes, and digital PVRs. However, it should also allow for a connection to a computer... at least in theory. Well, I am out to test that theory. After extended communication with my local cable company (CableONE) they have arranged to send out a pair of techs to help me try this out. The arrangement is for them to come out on September 22, and with phone support from their corporate offices and Motorola (the company that provides their set-top boxes) we are going to see if it will work."

wgadmin asks: "I am a sysadmin for a 500-node Linux cluster. We are doubling the size of our compute nodes, so, as a consequence, we need a new switch. We currently have a Foundry FastIron 1500 -- however, a) it doesn't have enough ports (only 208) and b) it is extremely unreliable. We want something that's solid as a rock. We process mostly serial jobs. And we will probably require ~320 ports. What's everyone using for their HPC clusters? There's so many high performance switches on the market, we hardly know where to start."

Nightshade queries: "I work for a department in a big financial company that uses equal amounts of C++ and Java. For a variety of reasons, we've decided that Java is the future of the group because of all the benefits of the language (it's so easy to use compared to C++, we can use Eclipse, Ant, jUnit, etc). The problem is that we do a lot of numerical computing and Java has no operator overloading! Languages like C# have operator overloading and because of this company's like CenterSpace have popped up with some nice looking numerical libraries. Try to find numerical packages for Java and it'll be pretty tough. What have people done in terms of numerical computing in Java? We currently use the Jama and Colt libraries for matrices and complex numbers, but these have awkward interfaces without operator overloading and are incomplete (no support for things like symmetric matrices) so we're looking for better solutions. So should we bite the bullet and switch to C#? Should we use a pre-processor like JFront? What have other people done?"

Roland Piquepaille writes "Several U.S. hospitals have found an innovative way to deal with nursing shortage. They post shift openings and the highest hourly rate they're willing to pay on their internal networks. Then, the nurses bid online for these extra shifts. The lowest bidders get the shifts and are notified by e-mail. This bidding process is almost certainly a good thing for the hospitals, but is it good for the nurses? Or safe for you? And what will happen if other industries also adopt auction systems? Imagine a company telling you, "Hey, you want to make some extra dollars by building this car or writing this piece of software? Name your price, and you'll make some more cash." What do you think of this bidding process? Read more before posting your comments."

dautelle asks: "I had the nasty surprise to receive a letter from a company in New-Zealand asking me to stop using the 'jade' name they have recently trademarked (my open source project has been Java Addition to Default Environment or JADE for short, long before their trademark filing date). I am going to comply, but I wonder if our open-source projects should be trademarked (cost >300$) to prevent such misfortune?"

hjf asks: "Three years ago, when I got DSL, I set up a 486 box, with 8 megs and a floppy drive to run FloppyFW. It has been through a couple hardware upgrades: 16Mb RAM for running the 2.4 kernel and a 100MBit PCI NIC for the internal network. It has a little UPS which lasts for over 60 minutes. The only downtime it has is when there's a thunderstorm and I unplug it. Besides that, it has been running flawlessly since I set it up. Lately I have been kind of seduced with this product from 3Com, and other similar to it. I know it says it can handle 253 simultaneous users and all that. My home network has 4 users, but most of us run eMule and other P2P, and as many of you know, those P2P programs can beat the crap out of your router."

Lithium_Golem asks: "My wonderful daughter will be nine months old next month and I figure that it's time to buy her some new bedtime story material. My problem is that I can't find any children's books that describe fathers as white collar workers, let alone computer geeks. For example, many of the stories I find portray the ideal father as a fireman, carpenter or truck driver. I'm not looking for anything specific like 'I love my dad because he's a programmer,' I'm just looking for a story that will help her understand what I do for a living when she's older. So, readers of Slashdot, does anyone know of a children's book written by or for geeks, or should I write my own?"

Gabe the Programmer asks: "I'm the lead developer for a website and we have a community there for gay/bi/tran athletes to talk to each other and interact. Well, not surprisingly, because of the sexuality of our members and the site's high profile, we get a bunch of homophobic/racist/hateful trolls who come on to the forum for no other reason than to incite our members and waste their time. Most of the trouble is caused by a cabal of users who hang out on Fightsport.com, and over the past three years they've managed to drag down the atmosphere of our community substantially." If users are going to be rude and disruptive to your community, it might be worthwhile to ban them. Be forewarned, however! This may turn out to be easier said than done, since saavy users can always try and work their way around site bans. If you were a site administrator, how would you deal with intransigent users, and if you were forced to ban them from your site, how would you go about it?

qm_37 asks: "I work for a small software company with a growing customer base. Our current support desk system has worked well for us in the past, but is going to become very unwieldy if it has to grow any more than it already has. We're looking for a more automated system that will do things like filter and direct incoming support e-mails to the support worker assigned to that task, assign and track support issue numbers, and give us a nice searchable database of previous customer issues. We've looked at various solutions ranging from commercial software packages to PHP/CGI-based server scripts, and nothing has really grabbed our attention. We have also considered writing our own system, but the trade-off is that we need to find the time to do it. Does anyone have any experience with a situation like this? Which route do you think we should take for our support system?"
