Phleg asks; "A professor of mine has been using TechSmith's Camtasia Studio software in order to take movies of what's going on on his screen. However, it's buggy, expensive, and a hassle. I've looked around the web for something that's GPL'd that can accomplish the same thing, and come up with nothing useful. The final stipulation is that it has to work under Windows, as much of the software he uses (Scientific Workplace, for one) is Windows-only. Has anyone found a (free) way to capture what's displayed on screen into a video, as well as grabbing inputs from a mic? Any codec would be fine." Those interested in a similar solution for Linux might be interested in this discussion.

An anonymous reader asks: "Is there anyone besides me who likes to travel and look at engineering projects? When I first read Neal Stephenson's Wired article on his trip around the world to watch an intercontinental fiber cable being built from England to Japan (still available at HotWired) I knew this was what I wanted to do with my vacation days. Space launch sites, high-speed rail lines, container ports, technology museums - I've tried them all. Does Slashdot have suggestions for destinations, or for web sites where people share their experiences."

bfrog asks: "I'm looking for a portable C/C++ client & server TLS library for Windows, Linux, Solaris, and Mac OS X. The license must be commercial-code-friendly. It seems like the choices are: the old standby OpenSSL; or CDSA . Apple makes a convincing argument for CDSA over OpenSSL in this PDF document , but I'm having trouble finding a mature CDSA implementation that's ready to go on all of these platforms. Perhaps I should use the best CDSA implementation for each given platform, and hope that the API's are compatible. That is, after all, the point of CDSA, right? Any suggestions?"

Saqib Ali asks: "A Tomcat/Cocoon setup can be used as a framework for publishing XML content. I have this setup running in testing environment for about 5 months now, and would like to move it into production. Is anyone using a similar setup and can comment on Tomcat's ability in handling the load from a production environment, or should we look at other Java Servlet engines like BEA, Jetty or Resin? If Open Source solutions can't work under these kind of pressure what should we be looking at in terms of different commercial solutions for publishing XML content?" A similar question with respect to Tomcat and Jetty was discussed in this previous discussion. What effects does using Cocoon have on Tomcat-based environments?

scraps asks: " I am assisting an evolutionary psychologist who is researching how symmetry and size of facial features affects how others perceive a person's personality. I am looking for is a way to increase and decrease the symmetry of faces (digital images, not the living flesh), as well as increase and decrease the size of facial features while maintaining a "normal-looking" face. In the days of yore, Gryphon's Morph software seemed to be the weapon of choice, but they seem to have slipped into obscurity. I am using Mac OS X 10.2, and have Photoshop 7.0. Any ideas would be most welcome."

candiman asks: "I am involved in developing a peer-reviewed journal to serve a large group of researchers who currently have no publication that suits their needs. To keep costs (both production and subscription) down we are looking to do it online, with one or two printed editions each year. We are a not-for-profit organization - we aim to break even, not make money. As the most web savvy person involved I am charged with developing the actual system. To save on wheel development time I have been looking for existing, free (beer and speech), management systems. We need something that is (relatively) easy to use for tech (but not web) savvy people. It must be easily extendable as the journal grows in size. It must be standards based (we don't want to be locked into any sort of proprietary formats). The ability to support subscribers and the ability to maintain both free and subscriber sections would also be useful (we are planning to charge a low annual subscription to access the journal's most recent edition - after three months the papers will be released to the free area). Does the Slashdot community have an suggestions or experience in this area?"

Rainier Wolfecastle asks: "I am looking for information on any webmail providers that support PGP/GnuPG encryption. Up until now I have been using Lok Technology's excellent service, but it appears that they have gone out of business, since their site has been unreachable for over two weeks now. I am aware of Hushmail, but that doesn't work well under Linux. I am considering using Name.Space's LokMail service (based on Lok Technology's..er...technology) but I was wondering if anyone out there has any other suggestions. Free email is coming to an end, and if I'm going to pay for it (which I don't mind at all) then I want a decent product."

no free lunches asks: "After giving up in disgust on layer 2 auth like *EAP/802.1x (which is a nightmare to configure properly and requires expensive access points and bleeding edge - flaky - firmware) I am considering controlling access to my wireless LAN (a small 50-user setup, with only one Linux user - me) using PPPoE, and would like to ask the Slashdot crowd their opinion."

An anonymous reader asks: "I just bought a Microsoft Intellimouse Explorer for Bluetooth for my Mac OS X 2.2 box. Like typical Mac fashion, it was entirely plug and play, no software required. However, I go to pair the mouse with the adapter in Bluetooth prefs and it asks me for a pairing password! Others on XP SP1 using integrated/third party adapters other than the one provided by Microsoft also report the same pairing password (on a side note, the MS adapter doesn't even pair with most Palms or Cellphones, what kind of standards following is that?). I called MS tech support and they gave me a weak 'It doesn't work on the Mac.' reply. So, has anyone managed to get this mouse to work on OS X, Linux, or XP (SP1 with a third party adapter)? Perhaps a cracked security password?"

non carborundum asks: "When using Windows I use Zonealarm because I like its ability to control outgoing packets. It's a good way to find out if some program is trying to call home. Zonealarm is much better than nothing, but 1 prefer open source solutions. Besides, it is overkill - I don't use it as a firewall, since I have a router, and it uses several megabytes of RAM. Better still would be a reverse honeypot - an app that catches outgoing requests, tests them against a database of known offending addresses and/or ports, and (optionally) tricks the offending application into thinking it has successfully phoned home. XP users in particular might be interested in such a tool."

cheesethegreat writes "Have you ever noticed how everyone breaks down into a near-religious frenzy when the topic of the "best" science fiction universe comes up? Everyone has a favorite universe, be it the Foundation Series by Asimov, or the classic Star Wars trilogy. So tell Slashdot what your favorite is, and what the most important part of a science fiction universe is to you."

Garfipus asks: "I have an Ericsson T60d cell phone that I use for cellular modem access. It works fine on a WinME laptop, but I'd like to use it on my PowerBook (and with a miracle, on my Newton 2100). I looked at the .inf file from the Sony Ericsson support website, and added the modem strings to a modem script under Mac OS 9, but it doesn't work. If I dial, the system doesn't see the modem and times out. A terminal emulator works, and allows me to issue commands. I can dial voice calls with ATDT, but that's about it. Any input on correct configuration settings for any non-Windows OS? I'd get a T68i (using that one is easy), but Cingular doesn't appear to support it."

hpavc asks: "I have played with watchdog daemons and hacks on and off for a while. I am wondering if there are any reccomendations out there for which real cards watchdog cards are of the best value. Or as some suggest is it all just a scam. From what I read the mechanisms of the cards differ greatly, both in their monitoring and their response. From simply watching an area of DMA to an embedded device with a os that monitors a large amount of things on the computer hardware and the environment. (tia)"

mikvo asks: "I work for my state Department of Transportation, and we have a reasonably advanced traffic monitoring system, currently with almost 300 cameras (and expanding). However, our matrix (300x200) video switch is running out of life, and we have to replace it. The primary consultant on the project is recommending we move entirely to digital video, using VBrick encoders and decoders. It's a private network, though we know there are still security issues around that. However, the primary question is, are there viable open source alternatives for both encoding and decoding the live video streams, rather than relying on proprietary (read expensive) decoding hardware?"

Richard W.M. Jones asks: "The Great Spam Archive received a legal threat today. A 'lawyer' claims that some spam displayed at the site is copyright, and must be removed. I'm claiming it's fair use for me to display an unwanted email sent to thousands (probably millions) of people at random. Is this fair use, or do they really have a case?"

PolicyWonk asks: "I just bought a new stereo, a Sony CMT-EP707, into which I intend to plug my laptop when watching DVDs, and my iPod when listening to music. When I first turned the stereo on I was horrified to hear interference from a local radio station, as well as a general hum emanating from the speakers. The hum and the radio emissions are audible even when the stereo's volume is set to 'min' and irrespective of what setting the stereo is on (i.e. Tuner, CD, or MD), or what input is (or isn't) plugged into the stereo. (I have tried my laptop, iPod, and no input). That means that during a quiet pause in a movie, or the intro to a song, this background noise is clearly audible. No amount of moving the speakers around the room, or plugging the stereo into different grounded outlets seems to fix the problem. I've checked my outlets, and they appear to have a ground connection, but I live on the fifth story of a circa 1900 apartment building in Manhattan, so it's anyone's guess what happens to the wires once they are in the walls. Anyone have any good solutions for reducing or eliminating interference from nearby radio sources?"

Spooky Suicide asks: "I own a slightly naughty website that among other things makes 20 some odd videos available for download in MPEG2 and MPEG4 format. I recently received a written letter from Acacia Research telling me my delivery of video is infringing upon some of their patents and I must choose between either licensing their technology or settling this issue in court. I called the EFF who told me they don't specialize in patent issues and don't know what to do next. Obviously, if all video on the web infringes on their patent, you'd think they'd go after the big guys, but they seem to be going after little content providers who can't afford to fight them in court. I can't help but feel like I'm being shaken down by the hi-tech version of Tony Soprano, what should I do? Anyone else dealt with these guys or no of any group of people grouping together to fight this?"

Theovon asks: "One of today's hot topics seems to be SPAM filtering. I have wanted very much to make my own contribution to this, but I have been thwarted by a patent. Probably before Paul Graham began working on his Bayesian SPAM filter, I began work on a Markov-model based filter. Things were going well until I posted to the usenet about it, and got this Google Groups response. This usenet post describes a Mitsubishi patent issued in 2000, US Patent #6,112,021. One of the key aspects of my design was that I would train the Markov model with both positive and negative examples. This patent is spot-on what I'm doing, because it deals specifically with the idea of using negative examples in Markov models to filter, among other things, 'inappropriate web content.' Well, the patent looks like a good one, assuming they really developed this idea. I mean, of course, I would think it's a good idea; I came up with it too, and it works very well. (Then again, I also thought it was 'obvious')..."

Hemos asks: "I've been collecting comics for almost two decades now, and have been looking around for some back issues that I've never been able to find in the local shops. I'm also looking to sell some of the comics that I already have. Any recommendations for the good places online (or offline) for buying and selling comics?" Come to think of it, so would I!

DigiWood asks: "Ok. I have been remembering the old days of BBS's. When you sent mail from one system to another it had to dial up and transmit it. Given the ability to wirelessly interconnect nodes in a city why hasn't anyone suggested that wireless server interconnects get put up? I know that people have 802.11b public access points. What I am talking about is aggregating these wireless islands together to form a sort of wireless backbone. A free wireless backbone. The only place you'd need a pop is the downlink into the hardwired internet. There could be multiple downlinks. With the advent of companies like Vonage that supply IP telephony the local telco could be cut out. I am not looking for a debate over which telco is worst. Nor any of the major media provider bashing as of late. Just a discussion of the whys and why nots to putting this together."
