anton[1452] asks: "AT&T Wireless has discontinued TAP dialup access to text messaging. I have used this for years to send alerts in the event of network outages. The alternatives they offer are not free and worse, require network connections - making them useless for my needs. Does anyone have a better way to do this without resorting to carrying a separate pager?"

5p1urge asks: "I really love the Mono and DotGNU projects. As someone who's worked in Java for for over 5 years, I welcome C# and it's buddies to the OpenSource world. However, here's question: as far as I can tell, only the C# spec and System.* assemblies were submitted to ECMA and therefore made officially public. What happens when MS decides that, Linux -is- going to steal valuable income-generating business, and therefore it should use it's newly acquired patents to sue? I'd appreciate comments from IT lawyers / solicitors and individuals with experience in this area, as well as from the wider community. I'm asking this question because I want to code in mono / DotGnu but I'm cautious because I wonder if MS can take it away from us?"

stan7826 asks: "I'm the sysadmin for the USGS Earthquake Hazards Program here in Southern California, and we currently run a small set of public mailing lists for earthquake information. We currently have a set of five lists. Two for long messages, two for short pager-style messages, and one for an ASCII-art map of earthquake shaking. People can subscribe to the list they want from our web page. But we are now looking at making this a statewide service, with a sort of cafeteria-style interface. We want for people to be able to select what events they get notified for by region, magnitude and message type. If I just create a mailing list for each combination, I get 24 different lists for California. This is just begging for some sort of database-driven virtual mailing list manager. Does anyone know of such a beast? (Preferably open-source, of course!)"

Richard asks: "I am interested in starting some home automation projects. The only requirement is that it needs to be controllable via my Linux based system. A Google search for ' "home automation" linux ' returns more than 35,000 hits, including some good ones like this one, which just show how MUCH is out there. Are there any recommendations for a good controller with a serial or USB connection to the computer? What about power switches and sensors? Do I want a system that sends control signals over my house's power lines or RF? Any good software recommendations? As a first project I thought a simple controllable power switch would be fun: Then I could ssh to my home system, use the power switch to turn on a computer controlled radio (Ten-Tec RX-320) and use Speak Freely to send back the audio to my remote location. (This works now except that I don't want to leave the radio on all the time)."

nissin writes "I'm ready to buy my first vehicle, and would like to hear your experiences with either hybrid or electric vehicles. Are they a good alternative to conventional vehicles, or just a geek toy? Do they perform well in the city? How about on long road trips? I am also interested in hearing about other alternative, yet practical, forms of transportation that I may have missed."

RobertB-DC asks: "Twice a week, for the past several months, I receive a call on my cell phone, from a 'Restricted' number. It's always the same: 'Please hold for an important non solicitation message.' It then tells me to call 1-800-842-0640 for further instructions. When I call (from a CID-blocked work phone), all I can get from them is the company name: NCO. They won't tell me more about their company unless I tell who I am. Verizon says they can't block the caller. Short of exposing my own identity to someone I don't know, how can I get rid of these annoying calls?" Are there cell phone carriers who are progressive enough to offer call blocking services of some kind?

grugruto asks: "A lot of open source solutions are available to scale web sites with clusters but what about databases? I can't afford an Oracle RAC license but can I have something more reliable and fault tolerant than my single Postgres box? I have seen this recent article that looks promising for open source solutions. Do anyone have experiences with clusters of MySQL , Postgres-R, C-JDBC or other solutions? How does it compare to commercial products?"

IgD asks: "My colleagues and I are developing an open source medical records system. A senior supervisor approached us and let us know a third party is offering a decent amount of money in the form of a grant for any legitimate medical research project. We were all but promised the money if we could come up with a proposal. Has anyone in the Slashdot community received a grant for open source software development? Are there any good examples of such a grant available? How could one measure the results of open source development for publication?"

eugene ts wong asks: "Our company is planning on taking care of its own email, by setting up our own server. I've been given the task of researching what is out there. So far, I've got my heart set on an IMAP server that we can install on Gentoo. Unfortunately, email isn't our forte, and I really have no idea of where to start. I've made some google searches, browsed around on the IMAP site, and also found this email. According to the mutt documentation, Cyrus and Courier are the best choices." What IMAP servers have you used, and which ones would you recommend?

Monty asks: "I'm currently exploring my options and I've been wondering, is it worthwhile to seek education overseas--specifically the EU? Edsgar Dijkstra was of the opinion, though controversial, that American and European CS programs were fundamentally different (see his later writings in the E.W. Dijkstra Archives). What makes the EU interesting, in that light, is that it seems to have more openly embraced things like functional programming. So, if I want to focus my study on something of a more functional nature, are schools in the EU a better choice? What are the implications of returning to North America for employment with a foreign degree? Do they have to be accredited as proof of validity or are they usually recognized by themselves here in the US?"

StudMuffin asks: "I am teaching a Master's level Introductory Java Programming class, at the University of Michigan in January, and am on the hunt for a solid Java textbook. This class is aimed at grad students (who obviously have a bachelors degree, so they are assumed to be able to think on their own) with no programming experience. Specifically, I would like to ground them in good Object Oriented principles, solid program design techniques, and finally in the actual syntax of Java. I would rather think of this as a 'How to program well' class that happens to use Java as the language over a 'Java class' that happens to cover programming. I would like to stay away from the applet heavy books that I tend to find, focusing instead on the topics above. Any ideas?"

blate asks: "Consumer-grade Firewall/NAT devices, such as those from Linksys, Netgear, D-Link, etc., have become very popular as more and more users get broadband connections. I've been using a Linksys router at home for several years and have never had any security problems. But how secure are these devices, really? The firewall guru's I know argue that a NAT really doesn't give you much beyond security-by-obscurity. What are your experiences with this (have you ever been comprimized through such a device)? Would I be better off with a Linux/ipchains firewall?"

Anonymous Coward asks: "DATs are currently the standard for recording legal concerts like Phish and the Grateful Dead. However, they're absurdly expensive even on eBay and are no longer being developed actively by any companies. Are there any alternatives that are more cost effective than DATs (Sony has a D100 out for 700 USD) and maintain the same quality? (DATs can sample up to 48kHz)."

Chris Curtin writes "My daughters' school is having a Career Education Day next month and I'd like to do a presentation. My kids are in Kindergarten and Third Grade, but I could present to Fifth Graders, as well. How do I explain what a programmer does to the kids? I was thinking about building a web page for the little ones, maybe show the older ones some visual logic with VB, where I change a basic program and run it from my laptop, showing keyboard and mouse inputs, music, and so forth. I have VB6, Java, HTML and Windows 2k on the laptop I'll be bringing. Any thoughts on how to 'wow' the little ones and make the older ones want to learn more about programming?" If you were going to make a computer presentation to a class full of children, what kind of things would you talk about?

soren42 asks: "I've been a casualty of war in the latest round of SoBig battles. Apparently, some of my user's e-mail addresses were in the address books of infected Outlook clients, and spam is now being circulated appearing to come from my domain. I'm getting almost 50 'Message Undeliverable' errors per hour, and I think I've been blacklisted from AOL and Earthlink. I know there are plenty of you are having this problem - how are you dealing with it?" Email viruses, once urban legends, have now become a real threat to certain people. What active measures can users (both vulnerable and non-vulnerable to such things) take to lower the propagation rate of such viruses across the internet?

Chris Frank asks: "With the RIAA stepping up its pressure on internet sharers, what is the legal status of people behind apartment routers? With no logging of who is moving what who can the RIAA prosecute when it tracks a shared file back to that specific shared internet account? I would imagine that many Slashdot readers are behind routers that hold all of their internal IPs private to the outside world. Is the bill payer responsible for all of the users of that router? How can a person be held accountable for the actions of others, especially when there is no proof of who did what?"

Saqib Ali asks: "I m sure most of you have heard that Connectix, the makers of Virtual PC/Server, have been acquired by Microsoft. Based on the technology acquired, MS has developed a new product called Microsoft Virtual Server, using which a Windows Server 2003 based server can run multiple operating systems concurrently. I am doing a preliminary analysis of using MS Virtual Server vs. running VMware ESX Server 2.0 on Clustered Linux Environment. Both solutions offer a way of running multiple OSes in a virtual environment using the same underlying OS (Windows 2003 or Linux). Of course, running VMware on Linux, offers the stability, scalability, and reliability of Linux, and also prevents a business form being locked into one single vendor. However running Microsoft Virtual Server does have some merits from a business perspective (vendor viability, reduced licensing costs etc). Any thoughts on merits/benefits/downside of using either of the technology stacks?"

nuggetman asks: "This year we're starting an in-high-school TV network. What we would like to do is be able to broadcast from anywhere in the building using our wireless 802.11b network. In doing some tests at home, I discovered 802.11b has enough bandwidth to allow me to send live video at VHS quality (320x240 29.97fps) w/ FM quality audio when using Windows Media encoder on the sending end, and Windows Media Player at full screen on the receiving end. When applied in school, the receiving computer would simply output the full screen display to a TV signal. Are there any other free (as beer) solutions that would let us do this, other than WMP?"

muirhead asks: "As a proud new dad, I made a web site to share some baby photos. Having seen this article about Google Bombing, I gave it a go and posted comments to Slashdot, Newsforge, Kuro5hin and LinuxWorld. Some of the pages have a high enough PageRank to show up as links into my site. Now, there are quite a few phrases that I can tell folk to google, and know my site will show top of the list. My favourites are Ruby Orange and Mutley Sleeps, but of course, I want more. What other free sites and means do you know of that I can use to further increase the visibility of my website?"

deijmaster asks: "For a couple of months we have been hearing (as a major consulting firm) IBM people pushing the possibility of installing a Z/Linux VM setup at one of our biggest clients (financial). To a Linux user such as myself this sounds great, at first. Now, I am a bit reluctant when it comes to managing this kind of infrastructure, with little or no local expertise at IBM. Has anyone gone through a Z/Linux VM corporate installation and lived through the management of such a solution?"
