Broadband-over-Powerline Experiences? 56

tarp asks: "I'm moving to the City of Manassas, Virginia, where ZPlug offers BPL (Broadband over Power Lines). The city was the first in the nation to offer BPL as an alternative to DSL or Cable. They claim a 300 to 500 kilobit per second connection speed, and rock-solid performance since the only downtime would be when the power grid goes down. BPL is also rolling out in other locations, despite campaigns by amateur radio enthusiasts to stop it due to interference. Anyway, have any of you used BPL, and is it something I should try rather than getting a DSL or Cable connection?"

Accurate ANSI Emulation in Mac OS X? 105

bedouin writes "I occasionally telnet to some BBSs that are very rich in ANSI graphics. While I can usually navigate fine through message areas and file boards, playing classic door games like Food Fight is almost unbearable. For about a year I've been searching for a Mac OS X terminal emulator that can accurately draw ANSI graphics just as they would appear on DOS systems with ansi.sys, but haven't found anything yet. Any suggestions? A native (and free or shareware) Mac OS X app would be prefered, but I'm willing to use an X11 or maybe even classic alternative as well. So far I've experimented with iTerm, GLterm, and aterm with unimpressive results."

Information Preservation and Data Havens? 413

tiltowait asks: "An interesting story on LISNews.com this morning about savvy U.S. students photocopying textbooks in Mexico then returning them for refunds got me thinking about data havens. There's already few places on the web where you can exploit countries having different copyright durations and eligibility. On the flip side, there's restrictions such as broadcast blackouts and country-wide firewalls. But just as the rich can use of international tax loopholes and in light of the recent file-sharing victory, are there any projects out there, beyond the P2P networks, to distribute possibly-protected information by any means necessary? For example, your company may already outsource labor, but what about an off-site backup in case of an FBI raid?"

USB Development Tools for Embedded Devices? 31

engywook asks: "I am thinking about putting a USB interface onto a real-time (home-brew kernel) embedded device, (naturally) with the intent that it talk to another device. I am thinking that it would be very useful to be able to monitor the USB traffic between my device and the other device, and between that other device and (say) a PC that already knows how to talk to it. Looking around, it seems that this capability is available, but at prices in the US$10K and up realm, which is a lot more than I can afford. I am looking for pointers to tools that would accomplish this for much less money. Any ideas would be appreciated! Thanks!"

Unix TCP Equivalent Settings in Windows 2000? 65

sameerdesai asks: "While working on a project that required client-server functionality I was running into processes that wouldn't finish and eventually hang. While running packet tracing, I found out the tcp_fin_wait_2_timeout setting on the server side (UNIX) was too low for the Windows client, and after increasing that value it worked great. I am trying to apply a similar technique for a Windows server and was wondering what the equivalent registry key is for UNIX's tcp_fin_wait_2_timeout setting? Also, is there a guide out there that compares TCP setting in UNIX with Windows?"

Transparent Aluminum Is Here 625

Alien54 writes "Scientists in the US have developed a novel technique to make bulk quantities of glass from alumina for the first time. (link includes a picture of samples) Anatoly Rosenflanz and colleagues at 3M in Minnesota used a "flame-spray" technique to alloy alumina (aluminium oxide) with rare-earth metal oxides to produce strong glass with good optical properties. The method avoids many of the problems encountered in conventional glass forming and could, say the team, be extended to other oxides (see also: A Rosenflanz et al. 2004 Nature 430 761). Scotty would be pleased."

Simulating Network Latency? 76

ixmo asks: "I've just come around an interesting problem: to simulate low-bandwidth network links without buying expensive WAN simulators, I can connect two old Cisco routers back to back with serial cables, and control the bandwidth via the 'clock rate' IOS command, but how can I simulate network latency? Is there some OS tool or patch (for Linux/OpenBSD) that allows for tuning of network delay? Any hints?"

Note Taking Devices for Students? 144

Gavin Scott asks: "I'm looking for solutions for a college student who needs an inexpensive mechanism for note taking in class. She suffers from a condition that makes writing notes out by hand slow and painful. One of the small sexy sub-notebook computers would be ideal, but at $1,500-$2,500 these are completely out of reach budget-wise. She has a perfectly good desktop system at home, so something that simply allowed typing in notes that could then be transferred to the PC would be ideal. I've considered things like a Palm-type device with an external keyboard, but I'm interested in knowing what other options people might suggest. Or any opinions on what kind of lightweight almost-laptop devices are good in, say, the sub-$500 range?"

Controversial StarForce Copy Protection Creators Quizzed 952

Thanks to FiringSquad for its interview with the creators of the StarForce copy protection scheme for PC videogames. The author explains: "In recent months there's been an increasing awareness and alarm over StarForce copy protection. It's actually a driver that installs itself with the [Windows] games that come shipped with it, and originally it didn't uninstall when the game was uninstalled." StarForce's Abbie Sommer argues the advantages of "driver-level copy protection", explaining: "The drivers are what prevents the use of kernel debugger utilities such as SoftICE, Cool Debugger, Soft Snoop etc. Also the drivers prevent emulators from spoofing a drive, and thwart burning tools such as Alcohol 120%." The author concludes by injecting a little personal opinion into the mix, arguing: "PC games will never go away, but if the market keeps shrinking due to the increasing ease of piracy... then the number and quality of games will almost certainly decrease."

Hardware That Literally Doesn't Stink? 683

gtaylor writes "You know that new computer smell? Some people (like me) get sick from it. Can Slashdot readers provide good suggestions for mice or keyboards made from ceramic, unlacquered hardwood, metal, etc, non-plastic headphones and microphones, screens like the new metal-framed cinema display from Apple, etc? (Wood is not necessarily right if it's glued or varnished.) I have a Sharp Plasmacluster air purifier that is very helpful but the fewer volatile organic chemicals released in the first place, the better. I'll also need a chair (leaning to the Herman Miller Mirra chair) and an adjustable metal/hardwood desk. High-density hard synthetics like polypropylene (a popular material at Ikea) or acrylic are also inert enough to be fine if they have no plasticizers - suggestions for a full office set-up welcome."

Sampling Short Sequences From Long MP3 Recordings? 278

mehl writes "I am a professor for social psychology at the University of Arizona and I am looking for help with finding / developing a special program. In my research, I ask participants to carry around a digital voice recorder while they go about their normal lives. The voice recorder then tracks the ambient sounds in their environments and produces an 'acoustic log' of a person's day. We then use these ambient sound recordings as source data for various person perception studies. For privacy reasons, we are required to sample brief snippets of ambient sounds instead of recording an entire day continuously ('Big Brother is listening to you...'). So far, we have achieved this by modifying the hardware of a digital voice recorder (triggering it with an external microchip). With the high turn-over in player models, however, this strategy has turned out to be short-sighted (every half a year we have to build a new chip). I am thinking about switching strategy, recording continuously in the first place (no problem with the current generation of flash memory) and then sampling (random) snippets after the fact from the continous recordings. Does anybody know of an existing program that can randomly (or pseudo-randomly; e.g., 30 sec every 10 min) and automatically sample short sequences from a day-long (18 hours) mp3 recording? What would it entail to develop such a program (for Windows)?."
Movies

What's the Worst Movie You've Ever Seen? 1675

prostoalex asks: "A recent Ask Yahoo! article talks about the worst movies ever made and points out this IMDB list of the bottom rankings. The Ask Yahoo! article names Manos The Hands of Fate the worst one, but apparently the IMDB table changed since then to include The Wild World of Batwoman at the top of the list. What would you consider the worst movie ever made? Perhaps anything listed here would also make the list?"

Communication Within Programming Teams? 93

aldheorte asks: "If you are a developer you have probably, over your time on various development projects, seen lots of projects with really awful code and some projects with really good code. You may also have observed that sometimes the projects with really awful code have a few excellent developers involved, while projects with only intermediate or mediocre developers are able to maintain a pretty good quality of code overall. The lucky few may have even seen that legendary situation of great developers and great code. I have always been mystified by this apparent discrepancy and I think a recent article on CSS development in a team environment may hit the nail on the head: 'The quality of code generated by a team rarely owes as much to the skill of the individual members as it does to the level of communication between them.' I am interested in the experience of others here on Slashdot. Have you observed this discrepancy between individual talent and a project's quality of code as well? How much of the success or failure of communication is based on the members of the team themselves as opposed to the management of the team, especially with respect to allowed time and deadlines?"

SP2 Community for Windows Developers? 38

kwelch007 asks: "As a Windows developer, I've been dreading the release of SP2, and the potential problems it could cause for my apps. So far, I've only run across one Win32 API function that doesn't work anymore. But, I haven't found any sites for developers detailing issues that others have discovered! Are there any sites/forums that developers can consult when attempting to determine why their code doesn't work with SP2, or even a BugZilla or similar to report such problems?"

Dealing with Intruders? 656

drakyri asks: "I've been running a server for a small company for a few months. Recently, the number of attempted intrusions has jumped from about one every week to several per day - and these are only the really obvious attempts, like idiots who try to log in as root from the outside. The problem is that I'm not sure what to do about this. I've got their IP addresses and can usually tracert their ISP's - is there an accepted type of letter to send them without seeming like one of the corporate cease-and-desist gnomes?"
