tengwar asks: "Under Windows I use a firewall (Zone Alarm) which can prevent individual applications from gaining Internet access, restricting them either to the local network or preventing any network access at all. This can be used to prevent Microsoft software and other trojans from calling home. I also restrict Outlook so that it can talk to my email server (which is on the local network), but can't pull remote content href'ed in a HTML email - helps with cutting the virus risk. I've also set it so that Internet Explorer has to ask for permission to access the Internet each time. I'm planning to move over to Linux as my main working environment, and I will probably want to use some Windows programs under Crossover - in particular I'll need Internet Explorer occasionally for getting to my banks, and I may need Outlook for work-related reasons. I'm not interested in iptables on the client (I think) as I've already got NAT and a hardware firewall guarding the network. Have you any suggestions on how to get the application-specific filtering that I get under Zone Alarm, for Linux?"

MISplice asks: "I have been searching for a Linux alternative to SASIxp which is a student administrative databse for K-12 schools (it does grades, schdeuling, and holds demographic and medical data). I have found the OpenSIS project which seems to be on hiatus and never past the implementation stages. Does anyone know of such a product or project that is under development? If not does anyone know if these types of products will work under WINE?" Have there been any new developments in this area since this article from 2000?

nojayuk asks: " Over the decades I've re-skilled myself several times, from mainframe FORTRAN through minicomputer PASCAL to microcomputer C. In between I've done microcontroller development and programming in Assembler, robotics, graphics design and 3-D animation for TV, PC build and repair, Website design etc. Currently I'm looking for work and I'm wondering what new skills do I need to stay in the computing biz. What OSes do I need to know, what technologies do I have to have under my belt for the employers to come hunting for me instead of me passing my obsolete CV around and being told to get lost? I'm looking for advice, not just for next week but for a few years down the line. What can I do to acquire these essential new skills?"

aagha asks: "I'm working for a very small, three-person startup in Athens, Greece (with a dwindling budget), trying to create the first real, full-featured tourism website for this country. While we have our home-grown Java-based Content Management System up and running and our site working fairly smoothly, we're having one heck of a time finding an ad management system to to work with our system. We have URL's which contain params to build our pages dynamically and we can't find a solution to work with our JSP's to serve ads targeted by category and or article. I know that I'm not the only person writing software for a JSP site (uhhh, or am I?). I'm curious to know what others have done to meet their advertisement serving needs."

joeldg asks: "I just recently decided to go open source with a project I have been doing for some time. After initially going open source I have had an avalanche of questions from users about what 'Open Source' means and how it will affect them. Many are scared of the implications and the broad new sweeping changes others could make in the project. My question is how do you alleviate the fears of over 5,000 dedicated users and get them to accept the idea of the project going open source and also keep some track of the project so that you can direct the current userbase to new sites running the code?"

dbaman asks: "I have previously used a router with my broadband connection and run cables thru my house to have a home network. Now I'm in a new house, and I don't want to drill holes in the wall and run cable thru the attic again. I have considered 802.11 wireless, but am more interested in the HomePlug Powerline standard, which lets you use the electrical outlets in the house as the network. Powerline uses 56 bit DES encryption rather than WEP like wireless, and is apparently a bit faster than wireless. LinkSys, GigaFast, and NetGear have adapters out, and a Powerline-based router from LinkSys will soon be available. Does anyone have any experience or advice with this new HomePlug PowerLine networking standard?"

An Anonymous Coward asks: "The new (Series2) TiVos have been substantially hardened from prior versions, but, it looks like it might be easier to get foreign program schedules into the TiVo than ever before. The newest units support APG, Advanced Program Guide (tm). This is a program guide being sent via the satellite broadcasts to DirectTV receivers. I'm trying to determine if this is a standard (by a different name) and the precise interactions necessary to submit this data to the TiVo. Basically, I want to emulate a satellite receiver sufficiently enough to submit new programming guide data to the TiVo. What I need to do this are sample data streams from a DirecTV satellite receiver to a TiVo, or similar device. Once this is done and working it will be possible to supply any Series 2 TiVo with program guide data for any region in the world (if such a schedule can be obtained). Note that this should not require breaking TiVo's subscription model."

chipperdog asks: "I am looking for an activly maintained console based word processor, similar to what one could find with Appleworks, from the Apple // era (Prodos 8 version, pre-//gs), or even one comparable to DOS versions of WP and Microsoft Word. An open-source one that compiles and runs in Linux would be best, although it would be nice to find one that could run on a 486DX2 50MHz with 8MB. A Google and Freshmeat search only turned up editors that seem to lack some of the necessary word processing features I am seeking. Although I mostly use VI (and *TEX when necessary), some no-so-geeky end users need the quasi-WSIWYG interface."

Michael_Angel asks: "If your hard drive has started to show garbled characters in the BIOS at boot, or just does not pick up. You may be victim to what could be the biggest hard drive manufacturer failure rate yet! Our company is small OEM system builder and we have been hit by a failure rate of %90 of the hard drives we purchased a year ago. We might be lucky because we stopped buying after rumors of hard drive issues 3 months after Fujitsu Limited made some major changes. IBM had a pretty crazy rate of failure and was telling people to turn off smart mode. I've called Fujitsu and they said that there is no problem! However, a simple search for bad fujitsu hard drives on any search engine will point to some angry folks. One notable link is this Register story." Has this problem followed Fujitsu drives into other countries, or might they be limited to the UK markets? Have you noticed an unusual failure rate in Fujitsu drives compared to hard drives from other manufacturers?

Kieckerjan asks: "A friend of mine, who's an architect, has been appointed a research position at a small university. Along with the job he's been assigned a budget to spend on whatever he thinks is necessary to get the job done. One of the things he needs is a fast machine to run Maya. As he is fed up with Wintel systems, he's been looking into alternatives. His eye fell on SGI's Fuel workstation, which costs about 15.000 EURO. For that kind of money you can buy a seriously bad-assed pentium-based system, and run Linux on it. His question to me was: is it worthwhile to shell out the extra money for a SGI system? Since I have no experience with modern SGI's, I am in no position to judge about performance differences, but maybe someone on this forum does."

smelroy asks: "My software company recently released a Linux port of our business instant messaging product, but we are not sure of the best way to sell it, since to many people selling Linux software is an oxymoron. Users on each end of the computer knowledge spectrum associate any and everything Linux with free. Even when we tried to get people to beta test it for us they said, 'It runs on Linux so why isn't it free?' Another comment from a reporter in response to our telling him of our Linux release was 'So it is open source then right?' So my question to the Slashdot community is when is Linux going to be prevalent enough on the desktop that people will pay for applications and not always assume they are free? Better yet, where are the people who feel that way now?"

blamanj asks: "There's a lot of open-source code around, and generally, it's quite easy to find. Finding open source data, on the other hand, can be quite a pain. Why isn't there a common reponsitory for public domain data sets? I'm thinking of things like lists of world cities, dictionaries of stemmed words, population data, etc., etc."

moonboy asks: "As plasma televisions continue to come down in price (Gateway even has a 42" available for $2999) I'm considering purchasing one. Has anyone here had any experience with these and particularly playing games on them? I'm thinking about both console and PC games however, I'm concerned about refresh and resolution. How do they compare?"

icewalker asks: "There has been a lot of news (here, here, and here) lately about music, copy protection, and other related issues. What I find interesting is that there are literally thousands of free bands out there that are more than worthy of listening too. Free as in they have not sold their souls (not to mention music rights) away to the devils of the music industry. But how does one get to listen to these pioneers of music? The solution could be sites like mp3.com (until the mp3 royalties are forced). But what people want is a locals only site that streams, guess what, the music from free local bands only. Not just for your community but local bands from all over the US (and the world). We need a site that collects these bands and we need a streamer that plays them. No CARP royalty problems since these bands are unsigned and own the music themselves. Make it so that the artists can hopefully sell their own CD's or single songs from the same site. Anyway, mix and bake at multiple bit rates and you have a solution to the copy protected CD (I haven't bought one yet from an Indie Band). The big guys go down because they can't compete with free, better than great music on the web with a low cost distribution. So, where is this utopia? Oh! And dump the necessary registration required to listen (are you listening mp3.com?)."

jallen02 asks: "CNN has a quick little piece in their technology section about the electronic voting systems and their security. They ask, 'What about security?' with regards to the electronic voting systems. And then a researcher from AT&T labs is quoted in the article. Basically, saying the systems should be open sourced, and he quotes the party line for open source regarding security: more eyeballs means more flaws are found and fixed. The big question raised here is ripe for debate.. should electronic voting systems software be opened for the public to see?"

lowvato asks: "I have recently been tasked with building two enterprise level portals. One is already in the making using Apache Jetspeed and the other is in the planning stage. I have been impressed with Jetspeed and its progress and versatility as a portal environment. One portal needs a very high level of security and interaction with disperate web services while the other is more of a community building service with CMS, forums, and so forth. Upon a limited review of the commercial portal solutions, I have found it hard to determine what they offer over open source solutions (especially since a few are based on products like Jetspeed or UPortal). I would like to hear what others have found using commercial and open source portal products."

Ktulu asks: "I'm looking for good books about wavelets applied to signal processing. I found one, 'Wavelets And Subband Coding' by M. Vetterli and J. Kovacevic (Prentice Hall) but it got quite bad reviews on Amazon. Are there good introductory and technical books you would recommend, covering wavelets, discrete wavelet tranforms and subband coding? Thanks."

icanoop asks: "I'm working on a project to help improve open source development using mature software process concepts. What process issues do open source developers think are most important and/or can be improved? If you are interested in seeing what is being considered read the problem statement at the project site. It's not final so feel free to suggest changes."

spacechicken asks: "I am doing a theoretical study of an extremely secure large scale data storage concept. Due to the nature of the (theoretical) location of the (theoretical) warehouse some of our constraints include very few (if any) service visits, complete remote administration and no moving parts. Does anyone have any experience using or information on large scale (on the order of 10^12 - 10^15 bytes) deployment of solid state storage? And to preempt those who will say it - I have Googled."

An anonymous reader asks: "My girlfriend has moved off to grad school on the opposite side of the country, and we've been video conferencing over GnomeMeeting instead of using the phone (we don't have landline phones, only cell phones, so we can't use the phone before 9pm w/o burning through minutes). GnomeMeeting works well, but we are tethered to our computers by our headsets (since headsets seem necessary to prevent echoing). Are there any inexpensive wireless computer headsets with microphones out there? I saw the DIY Bluetooth headset story, but I don't feel like scrounging for parts this time... I want to by a working headset right now. I've seen $200+ headsets out there. Are there headsets out there with roughly 20 meter range for less than $100?"
