sickofbluebins asks: "If one does a google on Why To Recycle there is a staggering amount of information on how recycling saves trees, resources, reduces pollution and generally is A Good Thing (tm). However, I recently read this article which comments that most recycling (besides aluminum) is not really worth it, and most of the recycling push is not based on science, but rather just by more politically based groups. I remember having people in my college classes be shocked when I informed them (being from a small town in the middle of logging country), that old growth forest was NOT being used for paper, as those trees produce the best lumber for things like houses and decks. The shock continued when I also stated in fact most paper comes from trees planted just for that purpose. All this makes me wonder how accurate the typical recycling information is. So I ask you, Slashdot readers, have any of you seen a true 'scientific' study of the benefits (or lack thereof) of recycling, especially renewable resources such as paper. I would really like to know what recycling really helps our planet out, and what is just a bunch of hype."

waynelorentz asks: "I've finally reached a point in my life where my time with my family is more important than my money, so I've given in to my wife's persistent urging and bought a Roomba robotic vacuum. While I'm waiting for delivery, I googled for additional information about it and found there is a fledgling community of Roomba hackers outfitting their Roombas with cameras and other equipment. So, it got me wondering - what other appliances have Slashdot-types hacked? I remember when the Internet was young, there were coffee and soda machines you could ping, and the fabled Jellyjet toaster. Anything else?"

StyleChief asks: "My employer has decided to begin migrating all of the company's documentation oriented objects and files to a new content management system. The new system seems to have good functionality, robustness, and better usability than our current systems. However, the task of migrating all of the data from 2 or 3 other repositories to the new system seems to be a daunting chore. Automating the process as much as possible is of course my first goal. There are APIs that one can use to do this, but the details quickly become eye opening. Questions of objects versus files, handling their attributes, authorizations, file type identification, shadowing, build integration, versioning, etc., are several of the plethora of issues at hand. Moving perhaps hundreds of thousands of objects from one proprietary repository to another while preserving everything related to that object is the name of the game. I would like to know how others from Slashdot have dealt with similar scenarios. I am particularly interested in the 'lessons learned,' and the problems that you didn't see coming beforehand."

InOverOurHeads asks: "Some of my coworkers and I are building a new datacenter for our company. We're a growing startup, we have about 50 servers now and expect to have about twice that before too long so building to grow is key. Now that we're about $15,000 in to the project, it is looking and feeling more and more like we were way over our heads. We have 4 racks wired to a single 20amp circuit. Our UPS is at 90% load and we only have 10 machines on it. We have all of our cooling on one side of the server room where it is about 60 degrees, the other side of the room where the servers exhaust is about 30 degrees warmer, so it appears that we have some convection problems with only a handful of the machines on, right now. We're realizing that there is a lot more to building a datacenter than racking servers, what else have we missed?"

bbulzibar asks: "I've been using MapQuest most of my life, but now as my mind is slowly expanding, I want to see if Yahoo! Maps is a better service for driving directions. According to one article I have read, Yahoo! is better at displaying maps, but what about calculating directions? Does anyone have any experience with differences? For example, Yahoo! and MapQuest give differing routes to go from Bloomington, IN to Madison, WI." I particularly like MapBlast's "Line Drive" direction style -- what's your favorite online mapping software?

man_ls asks: "I have recently run across the need for a network print server appliance, that can spool the data it is given and send it slower than 10 mbps to the printer. A client of mine has an Intermec label printer, with an internal processor too slow to accept data directly from the network without being buffered. Due to the system the client is running (OpenVMS) it must be connected to the network, it can't be local on one of the servers. Any ideas of a small print server box that can act like a spooler?"

Peter Miller asks: "I want to build a new firewall. I want fine control over the exact contents of the disk. So I went looking at Linux source distributions. Every one I looked at (Gentoo, Lunar, etc) put the development environment on the final disk image. I don't think this is good for a firewall. Even Linux From Scratch does this, it isn't automated, and the nALFS UI is incomprehensible. I'd rather not have the package database in the final image, either. Micro-distros like FloppyFW doesn't publish their root image build script, and that's the route I'd like to follow. What do you security zealots out there use to build your firewalls from scratch?"

He Definitely Didn't Inhale asks: "As anyone could imagine, being trapped inside a burning building would be terrible, but people risk their lives every day to save people stuck in that situation. While fire sprinklers are installed in some buildings they are far from ubiquitous, and also tend to cause plenty of water damage during their use. Some server rooms are isolated and can be filled with an inert gas in the case of a fire, but people - and fire - need oxygen to live. Another idea has recently been patented (USP#6,446,731), whereby a truck mounted high capacity fan is used to remove smoke and heat from burning buildings through the use of an extensible tube. This could make it much easier and safer for firefighters to rescue building occupants and put out the fire. Are any similar technologies or methodologies in use today? What are some design issues that may need to be resolved before this concept can be used safely and effectively? Are there any reasons not to pursue the development of this potentially life-saving idea?" Earlier this year, Ask Slashdot discussed Halon systems. Folks interested in this topic may want to give that previous article a read.

Pieroxy asks: "Most people like to make the analogy between DVD+/-R and the old VHS/Betamax/V2000 battle. This analogy is not applicable here, because whether you choose DVD+ or DVD-, you burn DVDs that are readable in most existing DVD players. Even if you buy today, the burner based on the technology that will die tomorrow, all your DVD*R will be readable in most DVD players. That said, what other argument than technical superiority can drive your choice? We know the DVD-R compatibility on existing players is better than DVD+R, we know that DVD+R as well as DVD-R have dual layers plans. What else can help me choose between either format? Are prices that different? Reliability? Speed?"

good soldier svejk asks: "I am a unix sysadmin at a medium sized (~10,000 user) organization. We currently using Exchange 5.5 for messaging, calendaring etc., and sendmail for mail routing and relaying. We arrived at this architecture because Exchange 5.5 was neither flexible enough to route our mail nor secure enough to meet our relay control standards (my Windows counterparts tell me it has since improved it's relay control). Now we are looking to upgrade to Exchange 2003 and the boss wants to know if we can eliminate the sendmail layer. We use LDAP mail routing across multiple domains and Brightmail Anti-Spam. We have not yet implemented Active Directory. Does Exchange 2003 offer a sendmail comparable level of configurability and flexability regarding routing, access control, filtering, virtual hosting and queue management? Just as important, is the Windows 2000/Exchange 2003-SMTP combination adequately securable for use in the DMZ?"

TheFuzzy asks: "I was just updating my resume, and came to the sudden realization that over half of the projects I've worked on in the last 3 years are under ironclad non-disclosure agreements (NDAs) and I can't list them. This leaves me with either a slacker's resume, or makes me insert vague statements like "advised 3 Fortune 500 companies on database performance issues" which sounds rather fictional. Attempts to get clearance from these clients to use them as references get forwarded to their legal departments, never to return. Have other Slashdot readers encountered this issue? How did you deal with it? Is it particular to the database field, or is it common for other specialties as well?"

bwhaley asks: "The University I work for has asked me to research software solutions for server monitoring. More specifically, a piece of software that will monitor server variables such as load, swap usage, POP/IMAP processes, total processes, and all the other interesting data about a server's health. Watching these variables can give administrators advance warning about potential problems with the server. We are currently using an in-house solution written in Perl but its age is showing. I have found plenty of proprietary solutions such as HP OpenView and Sun Management Center, but these cost thousands of dollars. What solutions do Slashdot readers use? Are there any powerful open source solutions that I'm missing? Is anyone else running homegrown software that they are happy with? We are running an entirely Solaris environment but I am interested in any UNIX solution."

ialbert asks: "I only recently decided to install SETI@home on my mostly idle home computer. It got me thinking though, are those free processor cycles truly free? Has anyone had experience with processors dying prematurely due to a constant, heavy load, or is usage pretty inconsequential? What about other components, like harddrives? And how much does a 100% processor load increase your power bill versus a 1-2% idle load over the course of a year? It's easy to think of idle computers as an untapped computational resource, but what are the costs to the computer owners?"

mzuckerm asks: "I am currently a law student doing some work with the Berkman Center for Internet and Society. Specifically I am working on a project called the Collaborator's Clinic, which provides resources for the open source community. I am currently trying to gather sample legal documents (including linking agreements, patent licenses, software development agreements, etc., you can look at the work in progress here) in order to annotate them with common sense descriptions of what the legalese means. This is very much like what the Berkman Center has done with the Chilling Effects web site (which deals with legal issues involved in cease-and-desist letters). Has this been done anywhere before? I have done a google search to try to find other sites including this information, but none I've found have included the information for free or directed it towards the Open Source community. Any help would be greatly appreciated. Also, if you are aware of any relevant licenses or legal agreements to which we could obtain the right to post and annotate, that would also be totally rad."

Ambush_Bug asks: "I've done some googling around, but to no avail. I'm wondering if the Slashdot knows of a remote login protocol which exists in security space somewhere between ssh & rsh/ftp/telnet. Basically, the point is that I don't care if my data are encrypted, but I'd rather not send my password around as plaintext. I'm sending extremely large astronomical images which don't compress very well (noisy backgrounds...) and sftp is just too slow, but our sysadmin isn't fond of rcp, ftp and the like. Is there something in between?"

Johnath asks: "One of the great things about finally owning a place with a garage is that it's given me a chance to start taking apart my car and putting it back together. I'm certain I'm not the only one here who does so. The analogies between custom cars and custom computers are as obvious as they are numerous: the quest for higher performance, the analysis of detailed benchmarking and comparison studies, the fanatical brand loyalty -- a nitrous tank on an inline-4 is materially identical in my mind to a 4" heatsink on an overclocked duron. How much overlap is there between these groups, how many people here are car geeks? My preference is to optimize for efficiency and mileage over power gains, but I'm interested in car-hackers of all persuasions. Where do you go for geek-level treatments of oil brands, exhaust options, and dyno results? Is there a gearhead Slashdot hiding out there, or only the brand-specific boards like myfordfocus.com?"

JAZ asks: "A few days ago a friend of mine and I were discussing this story. He was trying to make a joke about some content in the article that might be considered 'inappropriate' (the bit concerning 22,000 files). I didn't get his joke because the interesting bits weren't there. With a little investigation, I determined that my company's proxy server was delivering a modified version. Is this a common practice? Has anyone else noticed something similar?"

An anonymous reader asks: "I've just purchased a new 4 megapixel digital camera after always having a simple point and shoot for years. It has all the functions and controls for full manual operation of aperture, shutter, etc. Things that I know little about. I'm looking for information on websites (or books) that will help a novice like me learn how and when to use these features, not just define what they are."

altaic asks: "Today I was looking for a container format to store my anime collection (multi-language audio and subs), and I discovered popular media containers actually suck. AVIs are a hacked mess and don't even support multiple audio tracks. OGMs are catching on, but they don't have an index, nor do they support variable framerates (the fps value is stored in the header). I found some info on the Matroska container, which looks really cool (it supports multiple subtitle streams, multiple audio streams, a slew of other nice features), as well as the very young MPCF (mplayer container format). I'd really like to hear about other people's experiences with newer, more useful media containers."

gbulmash asks: "I'm looking to see just how much performance I can squeeze out of a new Athlon-64 system. This isn't for benchmarking, but more like you got a new car and you're looking for a long, straight road where you can push the needles into the red before letting off the gas (and then maybe a twisty mountain road to test cornering). Can the all-knowing Slashdot readers recommend some AMD-64 enabled/optimized distros and packages that will let us new proud papas of AMD-64 systems fully open up the throttle on these bad girls and see what they're made of?"
