Frustrated Son asks: "I assume that many Slashdot readers must serve as the IT staff for their parents. My folks get my old machines and just enough software to be productive. I try to protect my parents from the forces of evil by installing automatic OS updates, virus checkers, spyware blockers, pop-up blockers... But still I find that my parents end up with unwanted applications and dangerous software. What software or strategies do you use to protect your parents' PCs? Is it possible for inexperienced users to surf the net in safety?"

IgD asks: "Our small company has been a customer of EV1 for well over a year. We have a single dedicated server (a Red Hat box) and pay about $150/month. We get about 400 gigabytes per month for our bandwidth limit. Up until the SCO fiasco, we had been generally pleased with EV1. For obvious reasons we decided to move on. We didn't make the decision lightly. Migrating our server is going to result in a terrible inconvenience. The subject of EV1 and SCO has been covered in multiple articles here on Slashdot. Many have discussed moving to other providers such as ServerMatrix.com and ServerBeach.com. Dear Slashdot, where should we take our business?"

Nuclear Elephant asks: "After a little hacking, Linux has been running great on my Thinkpad T30 for about a year now. I can talk to my cellphone and bluetooth devices, do all kinds of neat hacking on wireless, and just about everything you'd expect to be able to do from a Windows machine, except make the battery last. Even after the standard optimizations (like cpufreq, laptop_mode, brightness, turning off useless processes, etc.) my battery still only lasts about an hour running under Linux as opposed to 2 1/2 hours in Windows. Has anybody come up with some innovative battery conservation ideas for Linux? It seems to be the only thing lacking in this fine operating system." What kernel options might one look into, for saving laptop battery power? Also, what desktop settings (both for Gnome and KDE) would work best, for this situation?

UNOStudent asks: "I'm currently a Biotech undergrad at the University of Nebraska-Omaha and have spent the past several semesters mentoring gifted youngsters and have been presented with a challenge this semester. My student is unbelievably smart, however has very limited social skills, is unable to cooperate with peers, doesn't understand why they make fun of his uncombed hair, etc. Since many of us may have grown up in a similar circumstance, I'm looking for suggestions from my fellow geeks on ideas for how to challenge him mentally, while building essential social skills." How would you build social skills in someone more concerned with math, science and computers?

hargass asks: "My US-based company is entrenched in AT&T. Now, as we look to expand our Blackberry 'fleet' from 1 to 5 units, I am struggling to determine which model will best suit our needs. My options are: the Blackberry 7210, dual band (1900 and 900 MHz); and the Blackberry 7280, tri band(1900, 1800, and 850 MHz). My users travel internationally, from London to Sydney to Beirut, and so on. I've researched what frequencies are most used outside of the States, and it appears that the 900 band is the most prevalent. However, the 7280 tri-band model doesn't operate on the 900 frequency. Is the 900 MHz frequency on the way out? Are the 800/850 frequencies the wave of the future? What are the strongest bands in Europe? Internationally, how much will not having the 900 MHz frequency hurt?"

quiddity writes "Following the Goofy USB Devices post, one has to know what can be self-powered when the batteries all die. You can handcrank your Gameboy, recharge your cellphone or pda (even grandpa), wind up a webserver (with minions, a beowulf..), see in the dark, and project a movie. What else can we propel through the next blackout/apocalypse?" Some of these devices have have been on Slashdot before; what cool hand-powered tech hasn't been and should be?

VonGuard asks: "Not all of you live on ramen and coffee. At some point, you have to cook, and the Internet should be a great place to find recipes. Is there a Google for recipes. And why isn't there a larger open cookbook on the net? So, is anyone working on this, or is there something the rest of us don't know about yet?"

Tha_Big_Guy23 asks: "According to this article, a man who created a website for his local Sheriff's department is being charged with extortion. This was caused by taking down the website after repeated attempts to get compensation from the county to cover the bandwidth costs. As a result, all his personal computer property, and company computer property was seized and he was jailed."

juuri asks: "Having spoken to a few friends it seems like troubles with cell phone portability here in the States is rampant. However today I ran into a new problem, it seems numbers aren't really portable if you move. For example if one has an LA number and moves to a different region (which vary greatly from carrier to carrier) you can not move your number with you if you switch to a new carrier such as Cingular or T-Mobile. Why not? You obviously already have the number and with nationwide roaming plans there is no reason for such distinctions. Even more alarming is that your new regional arm of your carrier may give you much trouble over your previous contract and basically refuse to give you service unless you sign up for a new, local region one. Does anyone know of a cell provider that lets you move your number, regardless of region?" It seems that the latest new thing for cellphones has turned into more of a flop, than a feature. Has anyone else run into this problem? Were you able to keep your number, or were you forced to change it?

An anonymous reader asks: "A friend and I are going into our final year of high school, and given a variety of factors (the relative paucity of technology jobs for HS students, etc.), would like to start our own business. We'll probably have about $1000 in capital, but (in effect) start out with no other resources other than our own skills (technical and otherwise). We have no constant access to a car, which means on-site tech support is effectively out. We'd like to start something in the technology field (IT, software design, hardware construction - we can solder, web design, etc.), but are open to any suggestions. We'd also like some sort of business we can start this summer, but can continue to maintain. What do you suggest as a business idea for the summer->longer term?"

cuzality writes "The media is now beginning to suggest that this recent onslaught of new viruses (with new versions of major-impact viruses being found daily) the result of a virus gang turf war, kinda like the India/Pakistan virus conflict, in which official Pakistani sites were savaged by such infamous groups as Indian Snakes and Indian Hackers Club. The gangs are shooting fast and loose: variations of the big ones are being discovered daily (as of March 4, we are up to MyDoom.H, Netsky.F, and Beagle.K), and in the space of three hours on Wednesday morning, five variants of these three were first discovered. Typically these viruses (or more correctly, worms) do little damage to the infected computer, intent mostly on spreading far and wide, and sometimes inflicting DoS on some poor evil empire."

Rinisari asks: "I've recently acquired a working keyboard from a IBM Thinkpad. It has ~87 keys, mousestick with left, right, and rocker buttons, and five other buttons: IBM, volume up/down/mute, and a power button (part number 08K4785). I want to make an interface cable, preferably USB but PS/2 will suffice, to be able to use this on my desktop. Has anyone ever tried something like this?"

sirshannon asks: "Frans Bouma's LLBLGen is a free, open source code generator that he licensed under the BSD license so that anyone could use it in any way, as long as they gave him some credit. Now Codease has released a product that apparently uses his code for 90% of the functionality but doesn't bother to attribute it to him. Frans lives in The Netherlands, Codease is in Singapore. What is the correct way to pursue this?"

2names asks: "Having been involved in cutbacks at several companies, I am finding it more difficult to remain focused on my job tasks even when I am not the subject of the cutback. For those of you who have survived the chopping block (sometimes repeatedly), how do you continue to produce quality work in the face of constant staff reductions?"

Anonymous Howard asks: "Lifestyle computers, otherwise known as 'computers with everything contained in a single unit', are extremely popular in Japan, where living spaces are much smaller then in the North America. Probably the most popular that I know of that was released are the Apple iMacs. Many of the major manufactures like Sony and HP have released Lifestyle computers, like the Sony PCV-W20. What I like to see are the unique stylings from companies I've never heard of over in Japan, like the Sotec Afina AS7180AV, I think it looks somewhat like a high heel shoe from the side. How many of you would find these types of computers useful? In particular, if you are living in a space where you are not cramped for space, would you ever buy one? Are there any other interesting machines like the Sonys/Afina/new iMacs that not only have function, but act as a stylish addition to the room?"

joshmccormack asks: "I've seen lots of projects where people are making great looking computers that fit into the dashboard of their cars that play MP3s, movies and even some that do some GPS and mapping stuff. I'd love to find projects where computers connect with the on board computers in most cars from the mid 90s on to show temperature and performance of various parts of the car. There are diagnostic tools that mechanics use, and that you can get to get data, but I'm particularly interested in real time, in-dash, open source options."

I-love-my-work, who is considering rejoining the IT world after a stint in business, asks: "A molecular biologist with a PhD at University of Birmingham, in the UK, quits his lab position to become a plumber, since a plumber apparently earns twice what he currently makes (~US$42K). How many of you would change careers if given a chance? What factors would influence the decision (money, hours, upper management, a chance to enjoy more of your life)?" What factors would make you seriously consider leaving your current career for another?

CSIP asks: "I am setting up a small mailserver, with ~500 users, across 80 domains. I'm planning to use qmail-scanner and an antivirus scanner to block incoming viruses. I would prefer to use ClamAV, however I've read conflicting reports on its effectiveness. The commercial scanners appear to detect 99.X% however they are licensed per-user, which at 500+ users becomes quite the annual bill. What is everyone's experience with ClamAV? Are their other commercial scanners that allow you to license on a per-server basis?" The best indicator of quality for a virus scanner is the information in its virus database. How do ClamAV's virus definitions compare to commercial scanners, like McAfee's?

cosyne asks: "Seeing the recent announcement about FreeS/WAN reminds me that there are many cool projects that I'm mostly unaware of (or, more often, completely oblivious to), which I only hear about when Slashdot posts a 'Developers finally giving up on this cool project' story. What projects (software or otherwise) are out there that would benefit from more involvement if only they had the publicity?"

Saqib Ali asks: "A DTD (Documentation Type Definition) defines the document structure with a list of legal elements. DocBook DTD is being widely used in creating Linux related documentation. However I am looking for a XML DTD that is more suited to internal IT documentation, and easy to learn and use. Preferably I would like to use a DTD that can be used with OpenOffice. What DTDs are other Slashdot readers using for for internal IT documentation? I have created documentation using DocBook DTD and hosted them on a Apache Cocoon . Cocoon lets me transform the XML to HTML or PDF. I would like to keep the same backend infrastructure (i.e. Cocoon) but try out other DTDs that are suited for IT related documentation. Any ideas?"
