EvilCabbage asks: "Let's imagine I have a distance to travel to get to my office. Much of this is done on a train line, but there is a distance of around 10klm (aprox 6.2miles) from my home to this train station. A little too far to walk, but not quite far enough to justify use of my car every day. Fortunately, the Segway isn't on my shopping list. I'm wondering what parambulating devices are available to make this journey a little easier, without turning the key in my car. Bicycles are generally too large to carry on the train, and couldn't be left in my office all day. I've seen some scooters that fold to rather small sizes (perfect for lugging to the office and back), but are these things still for kids? What small urban transport devices are fellow Slashdot readers using (assuming we are still going outside)? What can you recommend and what won't cost me an arm and a leg to run?"

eabell asks: "I'm buying a new mid-grade laptop computer, which I plan to dual-boot between Windows XP Home and Mandrake 9.x. Before its arrival in a few weeks I'm trying to think of what 'essential' software I'll need to make a usable home system. In general I'd like to spend as little money as possible (free is good). As far as my needs, think 'typical family PC' without an emphasis on gaming. I know I can get something like Open Office for word processing, presentation, etc. needs, but is there such a good thing as a good free virus checker? A good free email client? A handy web browser? What would you consider the top 10 (or so) pieces of software for a new home system, bearing in mind that I need software for both the Windows and Linux side of things?"

Asprin asks: "One of the employees at work had a major headache because a very important email was undeliverable for more than 24 hours. Sure, he got an warning from our server about it, but only after an entire day had passed, and the email was no longer timely. Therefore, I shorted the message handling timeouts to send 'delivery delayed' warnings after 30 minutes and to cancel the message as undeliverable after four hours. Now, I don't expect any of the other mail administrators here to bless these timeouts because they're way too short. HOWEVER, the truth is that my users rely on email to be as reliable as telephone messages, and if it can't be delivered immediately, it is better to reject it outright and alert the user so that other communication channels can be exploited such as fax or Fed-Ex. Is anyone else doing this? Are there any non-obvious ramifications lurking? Pros? Cons? Comments? Should we all reduce these timeouts on our SMTP servers?"

ynakai asks: "Today, I had the fortune to be allowed to play with demo applications in a CAVE. This technology is stunning, but what is the killer app? A staffer said that despite the potential use as a teaching tool for medical students, the system is rarely used now except by digital artists (who admittedly create some stunning experiences - try the VRML versions of some). Surely Slashdot can think up better ways to make use of a multimillion dollar room of fully immersive 3D interaction, besides FPS games?"

omasse asks: "I'm sick of telemarketing. Really sick. And since I'm in Canada, the new U.S. telemarketing law won't change a thing for me. The only easy solution is a technological one, and it ought to be fully transparent: No phone in my house should ring at all if it's an undesired call, and friends and family should not have to enter a 5-digit code to make them ring. To my knowledge, the only gadget that could do this is a sharp filter based on caller ID that I plug in my main phone drop. But Digitone's Caller ID Screener has been announced some time ago, there are no guarantees they'll meet their fall 2003 deadline, and I would prefer having a few products to chose from. There's been a discussion here once on a DIY home PBX system but that's way, way overkill for me. Could anyone tell me what are the ultimate Caller ID Screeners?"

zetes asks: "For a while now I have been a supporter of a horizontal server architecture/environment, where one server does one and only one thing and a business/department would then have numerous servers. This way if a service needs to go down (especially in a Windows Server environment), nothing else is affected. However, due to the rising importance of security in the last couple of years, I have decided that having fewer servers is both easier to manage and update and also provides fewer points of entry for hackers or virus writers. I am not going to a purely vertical architecture, where everything is on one server, but more of a hybrid (down from 10-12 servers to around 5). So what I am asking you all today is what you prefer to support or manage? One or the other, or a hybrid? And does the operating system or particular service(s) dictate this architecture to a certain extent?"

lockdown asks: "How do I secure the files used in my department? I work in an engineering department and I've been tasked with securing our electronic files. We are a likely target of pirates, both internal and external. The 'resale' value of our files is very large. Attackers would be interested in selling our files or just posting them publicly for bragging rights. While I trust our engineers, many of whom have been here over 10 years, we do have many short-timers and temps in other departments. Worst of all, our IT department is clueless and even hostile to our efforts. (They are proud that, 'our network is so outdated that it can't be hacked.') How do I came up with a way to secure our files in a hostile environment and still get our work done?"

drteknikal asks: "I'm the admin for a small law firm. We use our ISP as our secondary mx. We are receiving spam from our secondary mx even when our primary has been continually available. We suspect that spammers are routing to our secondary MX to bypass the DNS-based spam filtering on our primary. After examining some of the traffic, our ISP agrees. Neither of us sees an immediate solution, given the purpose and function of secondary MX. They already restrict relaying to hosts on their network. Has anyone else seen this? Does anyone have suggestions on how an ISP could secure their mail exchangers without interfering with the functionality required to function as secondary MX for an external domain?"

The Importance of writes "Last week, Slashdot readers provided a number of answers to the question "What is Music?" in the context of compulsory licensing. Now LawMeme asks another question about compulsory licenses: Why Only Music? Many compulsory licensing schemes have been proposed to cover music alone, but most of the arguments in favor of a compulsory license for music apply equally as well to other media types. Millions share movies, P2P can't be stopped, the MPAA hasn't provided legitimate alternatives for what consumers want, etc. If music should have a compulsory license, why shouldn't movies, software, ebooks and other media also be covered by compulsory licenses?"

aws910 asks: "I was in Las Vegas recently, and I noticed that most machines now give barcoded tickets as payment instead of coins. These tickets can then be used in other machines as a wager instead of paper money. A basic slot strategy is to move from one machine to another, and play machines in certain areas of the casino floor to improve your odds. With the ticket system, It seems all too easy for someone to build a system to track a player from one machine to another, giving the house the ability to kill the player's (already slim) edge. If a machine knows how much you've already won as soon as you sit down, do you think it will give you good odds? I couldn't find any articles on it. What does Slashdot think about this?"

Emperor Tiberius asks: "It seems more and more dedicated server companies are turning tail to the idea of hosting IRC machines. Hosts like Rackshack are adding 'no-IRC' rules to their AUPs at the risk of having one's server unplugged. Why is IRC (the once applauded chat medium) being thrown to the dogs? Some might say the horrendous botnets written for the protocol are a part of the problem. However, if we were to shut down the IRC protocol. Isn't it theoretically possible the botnet authors would just migrate to a different protocols like Oscar/AIM, ICQ, ICB, Jabber, just to name a few? If so, how would we manage the problem? Would we shutdown all ICB servers, and cut-off the ICQ network? Are we trying to kill off the problem in the wrong way, or is there a compromise to keep IRC alive, and keep botnets away?"

chthonicdaemon asks: "I am about to embark on a mission: to create a Free (as in freedom) chemical process simulator. My field is control engineering, and as such, dynamic simulation is what it is all about. There is an open source steady-state simulator called sim42, but I have not found one that can do dynamics. There is also a lot of work available in the form of implementation standards, so I am confident that it can be done. Is there anything like this out there that I have not found, and what open technology could I leverage to get this done faster (perhaps something like SML)."

StormShadw asks: "How do you manage IT requests in your organization? There seems to be a lack of software solutions specifically designed to track requests. Most that I've been able to find are either problem tracking systems or bug tracking systems, neither of which completely fit the 'request management' model. I work for a large bank and my department supports all of the internet web presence and online banking applications for the company. We receive hundreds of requests a week (my department has 51 people in it), typically through a variety of mediums (phone, email, hallway conversations). It's impossible to manage all these efficiently when there is no centralized system. What's the solution? What do you all use?"

Midnight Warrior asks: "I am one system administrator for what is an organization of dozens of LANs. Together, we all must keep our machines patched. Now we can all watch CVE, frequent securityfocus.com, or let LWN [Updated vulnerabilities section] bring things together. LWN does a fabulous job, but I'm looking for something bigger and more personalized that doesn't require the system be on the internet. Freshmeat, SourceForge, and Google are all NULL on this question: is there a database, and scraping agents in existence that will let one person oversee dozens of OS installations, a mish-mash of software packages, and an even worse level of up-to-date patching exist so that when a new vulnerability against, say, OpenSSH comes out, I can look up which systems need to be tested and patched? My work should be limited to maintaining OS (not just Linux distros), software versions, and current patch lists. This is a classic database problem, but has someone already solved it?"

worm eater asks: "I've been hosting my email with my web site host for some time, although a while back I used commercial services such as Yahoo! and Hotmail. I liked Yahoo!, but was disappointed to hear that they stopped offering free POP3 access. So I'm looking for a good, free webmail host for a friend of mine that supports POP3 -- because sometimes you don't want to have to deal with a web interface, no matter how well designed. And it's nice to be able to store messages indefinitely. What do you recommend?" This was last asked two years ago, but webmail is more prevalent now than it was then, so maybe better options are available. Readers interested in security with their webmail might find this discussion interesting, as well.

chensonny writes "Recently I was in a situation where there was no word processor, and several of us had to write, copy and sign a big amount of paper. It was then I re-realized the need for a good and comfortable pen. I saw some friends using a Mont Blanc, others like me using a felt pen or cheap ball-point pen. What does the geeks of Slashdot use for writing?" My favorite pen is an aluminum Lamy fountain pen -- can anyone recommend a good place to order Lamy ink in the U.S.?

An anonymous reader writes "I was recently asked by a coworker to come up with a list of <implied> expensive </implied> and cool gadgets for a VIP. He was interested in anything that was up-and-coming, rare and the usual odd combination of devices (ie. anything with a camera/WiFi that shouldn't have it). I figured that since it was Friday, it may be a good day to see what the /. crew has up their sleeves."

pstreck asks: "I've been going to a traditional university part-time for a couple of years now and am finding the pace slow, and classes to be at inconvenient times. So I have been considering transferring to one of the on-line universities like ACCIS or the University of Phoenix. How do you managers look upon a degree from one of these universities?"

mixwhit asks: "In our ever increasing effort against spam, we are now considering replacing all mailto: links on our website with something unharvestable (i.e. 'user (at) address', javascript mailto links, character entity evasion, etc.). Obviously this won't stop the spam, but it seems prudent to stop the harvesting so that the spam may slow down someday (year 2024 maybe?). What are others doing with this issue? We would prefer to preserve mailto link clickability, but also only want to make this adjustment once." One suggestion I would make is to put your email address in an image. People can read it, but harvesters won't be able to harvest it (unless they download the image for OCR), but any barrier you can place in front of the spammer, without blocking people honestly interested in communicating with you, is probably a good thing.

sangfroid asks: "As my personal technology products have increased, I've started to look more and more like a Batman wannabe. I now carry an iPod, a PDA, a Cell Phone, a Leatherman and a GameBoy (for the subway, really -grin-). Cargo Pants are out because of work and I don't particularly want to carry a back-purse everywhere I go. Is there a solution that doesn't require me to give up all my technology? A PDA/Phone might help but the holy grail would be a HD-based PDA/Phone/Music Player. How do you deal with all these devices without looking like a gargoyle? Is the answer better technology or no technology?"
