klausner asks: "I'm working at a large company that is trying to be more thorough about things like network security scanning. When Security told Operations they were planning to do this, there were immediate screams of anguish, and insistence that scans could only be done in the maintenance window, only with prior notice, and with a bunch of other restrictions. Needless to say, this is less than ideal. Given the size of the network, it would take weeks to do a single scan set. However, it is reasonable to take steps to ensure that the scans do not interrupt business traffic, or cause undesirable side effects like crashing target systems. What sort of limits are the readers out there using to ensure safe scanning? Limiting the bandwidth to a fixed percentage? Limiting the number of simultaneous tests? What other kinds of things can I do to limit the scans effect on network performance?"

Rorschach1 asks: "I work with a local Search and Rescue team, and for some time I've been thinking about the possibility of installing sensors at a few critical trail junctions in the local back country. The sensors would detect passing hikers and report timestamps to an Internet gateway in near real-time. When a hiker goes missing, this information could be very valuable in determining where search efforts should be directed. However, I've spent enough time on Slashdot to know that whenever you start monitoring or tracking people and their activities, someone's going to get upset. So I'd like to hear from the tinfoil hat brigade - what are your objections to such a system, and how might your concerns be addressed?"

An anonymous reader asks: "I'm going to a demonstration of some music software products tomorrow night. The music store hosting the event may be attempting to start a users group of music software. This seems like a job for open source advocacy! Anyone know of any good F/OSS for working with music and audio? I am already aware of Audacity and (Free as in Beer) Jeskola Buzz, but what else is there in the realm of sequencers and audio manipulation?" We did another helpful article back in 2001, and another from last August. What musical creations have you put together with any of this software, and others we may have missed?

RichiH asks: "The monsoon, started about a month early in India this year. While it is not sure if that is due to global warming or not, there are more pressing issues for the IT world at hand. Until about the end of July, there will be major thunderstorms in this area. How do you protect a network that is spread over 100 square kilometres in a land where the concept of a lightening arrestor is next to unknown? The network in question consists of about 2500 boxes of various kinds which are connected using 10BASE2 (aka BNC), 10BASE-T (aka RJ45) and 10BASE5 (aka thicknet), where only the last one may be new to some readers. The big question is: how can you protect yourself against these storms in a way that is both fast to implement and does not require laying of new lines?"

jjohnson asks: "As a coder I've been exposed to a lot of programming languages, big and small, and they're all in (pseudo) English, reflecting their invention and development in English speaking countries (or to gain traction in English speaking countries, such as Ruby). Of course, there's no reason a programming language couldn't be developed in Russian, using a cyrillic character set; or Chinese, using kanji; or Japanese, using hiragana. All three of those nations have big/advanced enough developer communities to justify the development of native-tongue programming languages, which have the obvious benefit of not requiring their developers to learn/code in a foreign language. What non-English programming languages exist, and how do they compare?"

niko9 asks: "After reading that development would be ramped up in the ACPI department of the 2.6 kernel series, I was hoping to finally get the one feature that Mac and Windows users have been enjoying for more than a few years: S3 Sleep, also known as Suspend-To-Ram. How important is ACPI and the sleep states on the desktop to you? Are there any ACPI S3 success stories on the Linux desktop out there? If yes, what hardware are you guys using? I would also welcome comments from Mac and Window users concerning their use of sleep on the desktop."

Schapht asks: "Not long ago, SourceForge.net started offering users and projects the ability to accept donations. But there doesn't seem to be much information on the legal implications of accepting donations. Should open source projects start registering themselves as businesses? Would there be fines if they didn't? Are there any options for a project that can't afford the processing fees involved in registering a business?"

Mattcelt asks: "I share my PC with my roommates, two of whom don't have their own PCs. In order to keep things simple, I have Windows98 running on it - they are used to the interface; it runs the programs they need to run from the University; and I refuse to pay the money to Microsoft to upgrade to a newer Windows OS. Unfortunately, there are some issues with privacy, and though I trust my roommates, there are work-related things I wouldn't want them to stumble into. Has anyone seen an email client other than Outlook that has -local- file security? Outlook has a feature to allow the password protecting of .pst files on the local drive, but it seems that every other email client figures that once the mail is on your machine, you don't need it protected any longer. Is there another email client with integrated password protection?"

iotashan asks: "Likely for most businesses, unsolicited faxes have become quite a problem. They needlessly use up toner and paper, and are usually just scams anyway. Specifically, we are receiving faxes from a company called Flamingo Travel. Now, they appear to bug business across the US, and some innocent parties are falling victim. I have used their automated system for having my fax number removed, to no avail. Is my only weapon having a bunch of friends call this 800 number to make the company's overseas toll-free phone bill unbearable?"

chimpo13 writes "I'm riding a 40-year-old, Italian made 250cc motorcycle round the world and doing a journal with pictures (avoiding the 'blog' word). Small bike, not much room, and I'm doing this on the cheap. There is no laptop because you can't trickle charge one. I'm looking for a flashcard to CD burner so I can post digital pictures. I need reliability, battery power, and hopefully someone makes one with an option to 'save for web' to speed up uploads in Internet cafés. Unless someone else has a better idea. I leave from Sydney Australia in 4 months if anyone world wide wants to give me a tour of their town, email me."

Bardaris asks: "In my work environment, I maintain a large number of Novell, and Windows servers. Although Novell is the dominant OS, vendor applications are increasingly making the change from Novell based apps, to single NT4/Win 2k servers. This has put a strain on my PDC. Currently the MS boxes are outnumbering my Novell 30 to 22, with more Win 2k servers in the coming months, as each application vendor has found it cheaper to dictate a sole Win server for their app, rather than sharing nicely on Novell. Now I've been tasked with assessing what to do with the Windows environment. My preference leans to eDirectory and dirXML to contain and maintain the Microsoft proliferation, but what of my NT4 PDC. Should I upgrade to Active Directory (if so, how)? Leave it as is until the last possible moment, whatever that may be? Is there a better way? I highly doubt I can sell a Linux/Samba solution, given the current state of the server environment and political climate here in my company, so that's not one of my options. I'm wondering if other Slashdot readers have ran across similar problems and how they tackled this issue."

An anonymous reader asks: "A while ago OEone released a thingy called Penzilla which was basically a Mozilla desktop environment like GNOME or KDE. Everything was written in either DHTML or XUL and ran within the Gecko engine. Recently a new project, Robin was released that is basically a desktop running within Mozilla using XUL as well. There is NetWindows that attempts something similar for more interactive web applications. What advantages would a 100% Mozilla engine desktop hold and what are the disadvantages compared to much more complex environments such as GNOME or KDE? Is a Mozilla desktop possibly more elegant or efficient for the typical user? Is the XUL runtime environment more robust than troublesome C/C++ widgets? It seems like most applications could make the transition as the growing collection of Firebird extensions like ChatZilla and Gnusto and have shown."

Anonymous Coward writes "I am building a museum exhibit which requires the use of 10 listening stations. These should be able to play back a few minutes of audio, should have an obvious Play button (and no other buttons: less confusion for the elderly and less to break for the kids), and should be able to work with an absolute minimum of supervision for three months of constant use. There are fancy ready-made solutions to this problem, but at $350, it would be too expensive to buy 10 of them. Similarly, there are cheap solutions ($20 CD player + $15 headphones), but this is probably not reliable or user friendly enough for this exhibit. Does the Slashdot community have any suggestions for how to build a reasonably inexpensive museum listening station?"

JeffTL asks: "By necessity, I carry around an Apple iBook running OS X Panther. In the event of its theft, I would like to have the thing send me its IP address, not only for the benefit of law enforcement but also so I could SSH in and trash my personal data with srm, while doing an SFTP backup of anything I forgot to back up. I am not really wanting a subscription, so I am looking for a free-as-in-beer (and if anything beyond a shell script is involved, free-as-in-speech would be much preferred to make sure that no one else is getting anything). Currently, I have a bash script that can create a report, and I am thinking about sending it using either e-mail or FTP. I am considering setting it up to where it only starts barraging me if a specific code is posted to an HTML document of my choice. Is there already something like this in existence somewhere for free? If not, does anyone have any pointers on how this can be done?"

josh asks: "For my next project, I've decided I want to do something related to x86 virtualization (the way VMware does it or Plex86 not Xen/Bochs/etc.) but I really don't know where to start. Googling hasn't been helpful (just look at the results if you don't believe me). Are there any resources for learning about this kind of x86 virtualization? I know virtual 8086 mode wouldn't work, but without that what advantage does something like VMware have over something like Bochs? Are there any F/OSS projects aimed at something along the lines of my thinking? Please enlighten me with any references and resources you might have. Thanks!"

PeteQC asks: "I'm currently working on a project and I need solid and well documented case studies about actual implementation of open source in an enterprise (failure or success). My goal is to use the grounded theory to build a scientific model on Open Source adoption. I've searched through the web, but the only good case I found was the Beaumont Hospital Case. (Which was also published in IEEE Software, January/February edition). I'd like to know if Slashdot knows of other well-documented case studies which I may use? I'm looking for a link to a web site or a reference to a specialized publication, but all assistance will be welcomed."

zachjb asks: "With all of the recent articles and buzz in the technology community regarding recordable/pressed optical disks being an unreliable medium to backup your data on, I figured the best way to keep my data alive is to duplicate my CDs/DVDs every few years. I've searched Froogle for CD/DVD duplicators, but I have no idea what I should be looking for. Does anyone in the Slashdot community have a lot experience with this type of equipment? Is this a reasonable solution to the problem or is there a more cost effective one?"

The Real Joe Faith asks: "The O'Reilly book 'Java in a Nutshell' used to include a really handy introduction to Java specifically aimed at C++ programmers. It meant an experienced programmer could re-use their knowledge and get up to speed quickly. But what about going the other way? I know a fair amount of Java but, for my sins, have always avoided C++. Now I need to learn it. Fast. Not just the syntax, but also about the various standard libraries out there. Now that Java is the standard language on most computer science courses I guess there will be a few people in the same boat. Can anyone recommend a good book (or any other information source)?" For those Java programmers among us who have gone this route, what books did you use to assist you in the transition to C++? How well did these books work for you?

dangerz asks: "I'm in a class right now that gives you a client and you must design a site for them for free. My class was split up into a group, and I am the Project Manager / Lead Programmer in the group. Our client is a group for Disabled and Elderly People. Basically, what we need to do is create a site for them to sell their art work. We had a meeting with the board of the organization today where we explained the basics of a website and what we'd need from them to move on. They learned pretty quick, but there are some things they want that we think aren't aesthetically pleasing. Has anyone ever had to do a site where the target audience was elderly or disabled people, and if so, what steps did you take to make sure everything was simple and accessible?"

GabrielStrange writes "I've been thinking for a while now that I'd like to own some sort of portable device on which I could read e-Texts. This device should be able to read both simple text files (i.e. Project Gutenberg e-Texts) and more complex formats, like Plucker, Acrobat or Microsoft Reader. It should have a fairly high-res display with a backlight that would be easy on the eyes... but doesn't particularly need to be a color display. I'd like it to work with at least one (if not both) of the machines on my desktop, which run Linux 2.6 and MacOS X Panther... And to use a USB port. And I'd like it to have a built in, rechargeable battery, because I already have enough devices to worry about batteries for. And, of course, I don't want to pay very much for it. Anyone got any recommendations for such a device? It's proving to be almost impossible to even obtain an actual list of devices that have these features."
