DC Power distribution - Nix the Transformers? 180

Posted by Cliff from the we-call-'em-wall-warts dept.
MailtoDelete asks: "I have most of my electronic gear plugged into a couple power strips hanging off a UPS. Most of these devices have big block-type transformers which, besides being bulky, are a bit of an eyesore. I have been trying to find a product out there somewhere that would allow me to have one central transformer that would distribute DC power at variable voltages, depending on what devices I wish to plug into it (think one AC input and 9 or so DC outputs individually adjustable). I found this device that resembles what I have in mind, but it does not have sufficient output for my router, switches, and various other devices. Is there a product on the market already that would do this? Can I build one with my marginally above average soldering and electrical schematic skills? Have any of you found a better way to eliminate these blocky plug-hogs?"

Comparisons of Non-Linear Video Editing Packages? 53

Posted by Cliff from the how-well-do-they-rate dept.
kickabear asks: "I'm working on an independent (that means I'm poor) film. I'm looking for a site (or a book, I'm not picky) which reviews various non-linear video editing packages. I've found a few sites but I can't really find anything that does a side-by-side comparison of the features and capabilities of products such as Premiere Pro or Avid Xpress Pro or the 20 projects listed on Sourceforge. The project will be filmed using a brand new Sony HVRZ1U HDV camera, so if any comparison sites lean toward HDV/HDTV, that would be favorable. Any information, war stories, or advice would be appreciated."

Best Leatherman-Style Multitool? 200

Posted by Cliff from the a-toolbox-on-your-belt dept.
An anonymous reader asks: "I'm in the market for a Leatherman style multitool, but some new players have come to the table in the past few years, and I've heard a couple of anecdotes that Leatherman might have been eclipsed. So, I'm asking Slashdot for lots of anecdotes; what are your experiences with your multitool? What's the best one you've seen or used? Have you ever broken one? Do the tools wiggle around after a lot of use? Those are some general questions, but there are two specific ones. First, does the knife blade lock? The quickest way to hurt fingers is using a folding knife when a fixed blade is the right tool, but you can't carry a fixed blade knife into many places. The second question is, how long is the main knife blade? You can't carry a folding knife with tool long of a blade, either (unfortunately). Thanks for any and all help!"

Network Monitoring and Alerting? 59

Posted by Cliff from the centralized-fault-detection dept.
SpamMonkey asks: "At work I am trying to implement a central monitoring and alerting service. We have in excess of 250 Windows servers, approx 15 AIX servers and another 30 Linux servers (mainly SLES/Suse). My investigation into systems that will allow us to monitor critical areas on each of these systems has so far led me to a clustered Linux server running Nagios with passive and active checks. What I'm curious about though is how Slashdot readers are carrying out their own jobs and how they can comfortably sit back, without having to repeatedly check that various systems are still operational and how to cut down their own response times when something goes wrong."

Non-Technical Managers in a Technical Company? 438

Posted by Cliff from the oil-and-water? dept.
Futurepower(R) asks: "Before he was hired, Steve Jobs of Apple told John Sculley he was a sugar-water salesman, and perhaps should have listened to his own words. Under Chairman and CEO Louis V. Gerstner, Jr, IBM did well, but was that only because the world needs a global computer service company? Was IBM technically advanced during his tenure? In your experience, can managers with little technical knowledge successfully run a technically-oriented company?" What qualities would such a manager need to keep a tech company healthy?

Starting a Political Career with Open Source? 66

Posted by Cliff from the if-you-must-fall-to-the-dark-side dept.
byronmiller desires to get to the root of the following issue: "I have chosen to run for office to represent the people of the 16th district of Pennsylvania. I am looking for software and solutions to help manage a grass roots and budget friendly campaign. What applications are available for everything from district management/contact management solutions to online fund raising and campaign management solutions? We are already rolling out staff PC's running Suse 9.2, OpenOffice.org and of course Firefox. Are there any collaboration suites and mail systems that we can use for calendaring, notes, email and conferencing? Anyone build a campaign using open source technology or is Politics still only putting money where your mouth is? Technology is a major initiative of my campaign and i'm very interested in what political software and civic solutions are available - especially experience and reviews of such."

Home Routers w/ Decent QoS Performance? 52

Posted by Cliff from the from-the-office-to-the-mainstream dept.
danwarne asks: "With VoIP becoming rapidly more popular, quality of service (QoS) settings in home routers are also emerging as a key piece of functionality for the average user. QoS settings, which allows important or time-sensitive network traffic to be prioritized over less important packets, used to only be offered for corporate-level routers. Now, many hardware manufacturers have started including such capabilities in their mainstream routers, some doing it simply by a firmware upgrade without any change to the power of the underlying hardware. The emerging problem is that most home routers don't do a very good job at all with QoS, especially under heavy load (from P2P apps, for example), and home routers don't seem to have what it takes to prioritize sending Voice over IP packets first, leading to glitchy VoIP calls. VoIP operators around the world are facing this problem as they try to turn VoIP into a 'consumer-friendly' plug-and-play service. Does anyone know if someone has done extensive testing on home routers and modem/routers that investigates their ability to deliver QoS? Also, what hardware elements would be required in a router to do QoS reliably?"

Building a Simple Streaming Media Server? 51

Posted by Cliff from the on-demand-tunes-remotely dept.
neomage86 asks: "I'm looking for a simple Network Jukebox. I want to be able to stream media from a Windows (it has to be Windows for other school work) server to remote machines over a LAN (only 1-2 clients at a time). I want to be able to choose the song that's playing from the remote machine, video would be nice, but not necessary, and it should be free (as in beer, I'm a student). Any ideas?"

Project Management Methodology for IT Operations? 163

Posted by Cliff from the transcending-the-programmer's-cubicle dept.
sleeperservice asks: "There are a multitude of books, tools, and educational programs that deal with managing development projects. Whether you subscribe to IBM's Rational Unified Process or maybe SEI's Capability Maturity Model, whether you read Tom DeMarco's Peopleware or possibly Brooks' Mythical Man Month, there's something out there for you. However, most of these deal with projects that have a heavy amount of development, often new development associated with them. What about the folks in Operations? Let's say you need to upgrade your Oracle-based data management system for 1000 non-technical users? Or maybe you need to migrate your enterprise off of Outlook/Exchange and onto an alternative? What pointers are out there that Slashdot readers have used in such situations?"

Battlestar Galactica Available for Download 357

Posted by CowboyNeal from the free-starbucks dept.
blankgm writes "The SciFi channel has made Episode '33' (Season 1 Episode 1) of Battlestar Galactica available for free, uncut and commercial free, online at SciFi.com. Also available are deleted scenes from the series. Is this a ploy by the SciFi channel to grow a viewer base as well as loyalty, or an extremely bold move since the series isn't even out on DVD yet? Hopefully it's both. In either case, I believe this is unprecedented, especially since season 1 hasn't even concluded here in the states. Bravo SciFi. Keep 'em coming!"

A Linux Presentation Repository? 18

Posted by Cliff from the a-decent-starting-point dept.
literate asks: "I just presented the third of three lectures advocating the use of Linux and Open Source software. The first two were at the Desktop Summit Conference and SCALE3X, Southern California Linux Expo where I presented on the subject of the use of Open Source Software in small schools. Last night I presented on the use of Open Source software to secure business communications for the monthly meeting of the Open Source Software for Business Peer Group of Tech Point Indiana's largest technology trade group. Linux & FLOSS advocacy is my way of giving back to the community. There were dozens of great presentations at both conferences, which made me wonder if it might be time for someone to start collecting the best presentations, and make them available for quality presenters so that they can leverage these incredible resources beyond the one or two uses they might otherwise have?"

Build High-End Audio System w/ Hard Drive Storage? 93

Posted by Cliff from the audio-components-that-have-caught-up-w/-the-tech dept.
nganju asks: "Hard Drives have finally reached the size where I can rip down 1000 CDs directly to WAV files, and skip the compression step (read: headache) altogether, ensuring that the audio playback is what the original CD author intended. Now the question is, how do I get that WAV data off the computer and into the amplifier with minimal distortion? Are there D/A PCI cards comparable to high-end CD players? Or is the best solution some direct digital output card (SPDIF) and a standalone D/A converter component? Specific model names would be greatly appreciated."

Optimizations - Programmer vs. Compiler? 1422

Posted by Cliff from the who-can-obfuscate-better dept.
Saravana Kannan asks: "I have been coding in C for a while (10 yrs or so) and tend to use short code snippets. As a simple example, take 'if (!ptr)' instead of 'if (ptr==NULL)'. The reason someone might use the former code snippet is because they believe it would result in smaller machine code if the compiler does not do optimizations or is not smart enough to optimize the particular code snippet. IMHO the latter code snippet is clearer than the former, and I would use it in my code if I know for sure that the compiler will optimize it and produce machine code equivalent to the former code snippet. The previous example was easy. What about code that is more complex? Now that compilers have matured over years and have had many improvements, I ask the Slashdot crowd, what they believe the compiler can be trusted to optimize and what must be hand optimized?"

Stem Cell Injections Pioneering Step Forward? 359

Posted by Zonk from the general-medicine-indeed dept.
sanspeak writes "Indian Doctors at All India Institute of Medical Sciences have performed a radical new operation of sorts by pioneering the method of stem cell injections. Ishika Gupta, a seven month old girl child who was suffering from cardiac myopathy, was treated by injecting stem cells into her heart from bone in her own leg. AIIMS has marked a global first in pioneering stem cell medicine by the "injection method''." From the article: "There will now be a national stem cell centre at AIIMS which will coordinate the research and its applications. The statistics speak for themselves. After six months, 56% of the affected (dead muscle) area injected with these cells had shown improvement." Additional details on this therapy available from the Fort Wayne News-Sentinel and Medical News Today.
