The Electrocharger...Any Day Now? 98

Posted by Cliff from the more-performance-gains dept.
bigmoosie asks: "It has been over a year since the Electrocharger was discussed on Slashdot. It appears to be almost ready for production, or is it still vaporware? Does the Slashdot community think an electric motor replacing the alternator on an internal combustion engine will add 5, 10, or even 15 mpg? How well do you think the super capacitor battery pack will hold up at -20 degrees Fahrenheit? Are there any other products out there that do the same thing? I know this is not as efficient as a hybrid car made at a factory, but it can reduce the fuel consumption and emissions for cars that are 5 or even 10 years old and still on the road. Does have the potential to be an environmental friend or disaster (how long does the battery pack last)?"

Why Does Current Clustering Require Recoding? 75

Posted by Cliff from the reinventing-the-wheel dept.
AugstWest asks: "I've been doing some research into what the available clustering options are for pooling CPU resources, and it looks like most of the solutions I've found require that programs be re-written to take advantage of the cluster. Since there are virtualization apps like Bochs and VMWare, where the applications just make use of a virtual CPU as if it was a real CPU, why aren't there clustering solutions that do this as well?"

Changing a Windows Network to Linux? 150

Posted by Cliff from the OS-defectors-anonymous dept.
Charli125 asks: "I have been a Windows administrator ever since I got into the tech industry. I have no working experience with any other OS except for those from Apple. I am currently working with a small company that has 1 server and around 15 workstations. I would like to faze out all of the Windows software, in order to avoid having to deal with viruses, save money, and learn how the other half lives. Since I have never so much as installed Linux, I am looking for resources or advice on how to get started, and how to plan the change over. Can anyone help me?"

What's On Your Tech Bench? 530

Posted by ScuttleMonkey from the oh-to-have-an-unlimited-budget dept.
Twev1701 writes "As a small computer repair company that has seen enormous growth in the past few months, we are now looking to expand our facilities. With construction starting on our office space, we now turn to the task of designing a new tech bench. Our existing bench is 6'x3', has a dedicated 15" CRT, 4 port KVM, and overhead storage bins for parts. With a new bench of 12'x4', we have lots of room for expansion. What essentials would the /. community put on their new tech bench?"

What is the Current Status of WiMAX? 239

Posted by Cliff from the last-mile-broadcast-broadband dept.
PalletBoy asks: "I live in BFE (read 'remote') Pennsylvania where BroadBand is not available in any form save satellite, which is no good for price and latency reasons (curse my MMO addiction!). My big question is: what is the -actual- current status of WiMAX technology? Different sites have me believing different things and I can't find an exact answer to the question 'When will I be able to buy a WiMAX router and cards so I can remotely receive broadband?' When will WiMAX (802.16) be solidly standardized, out, and affordable? Or is it already there?"

Preserving Old Research Notes and Documents? 101

Posted by Cliff from the reclaiming-space-from-unnecessary-paper dept.
twistedcubic asks: "I have several thousand 8.5 x 11 inch dead tree pages of notes and research that takes up too much storage space. I would like to have all these notes scanned into PDF files (for example) so I can recycle the pages and reclaim storage space. Does anyone know of a store that provides this service, or an inexpensive machine that will do the job in a reasonable amount of time?"

California Legislature Passes Violent Game Bill 218

Posted by Zonk from the no-love dept.
404Ender writes "In a move similar to the passage of a law designed to restrict the sale of violent video games to children in Illinois, California is now awaiting only the signature of Governor Schwarzenegger before a similar bill becomes a law. Does this action signal the start of a disturbing trend of the restriction of First Amendment rights? How can we as gamers fight back against this type of government action?"

Hybrid Vehicle Conversion Services? 151

Posted by Cliff from the another-way-to-beat-high-gas-prices dept.
OverkillTASF asks: "My '94 I6 Jeep Grand Cherokee has once again eaten through a transmission... at 105k miles. For one reason or another, this has led me to the following question: Are there any companies/individuals out there who do hybrid vehicle conversions? I'd like to retrofit my Barbie Jeep with the necessary equipment to eek out 5 more MPG, be a little more environmentally friendly, but still allow me to get where I need to go out here in the sticks? Do such after-market conversion services exist?"

Does Legal Online Video Content Delivery Exist? 45

Posted by Cliff from the digital-cable-has-it dept.
RingDev asks: "I'm working on a system integration project for my CIS capstone. One of the systems we are integrating is a Windows MCE PVR. One of the topics that came up implementing a movie on demand or rental system using an existing online content provider. But the question we have run into is, are there any? Is the only option for online video content (TV shows, movies) P2P and BT clients? Is there no company out there that handles licensing and provides DRM'd content?"

Searching for a Decent Scanner? 425

Posted by Cliff from the what-would-you-recommend dept.
Stumped about Scanners asks: "My little sister's scanner is acting up, so she's in the market for a new one. However, the software she wishes to use it with (some funkadelic 'music OCR' thing that lets you scan sheet music and transforms it automagically into MIDI files) claims that it doesn't work too well with HP scanners. And, truth be told, I've never known much about which scanners are good and which are crap. So, which scanners lately are decent? Which are crap? I know that DPI matters very little (just like it does in printers)-- it's quality that matters. Could the SlashDot community provide some info on which scanners (some from HP and some not from HP) are decent? Are there any quasi-reputable sites (a la Tom's Hardware?) that have reviews on such things?"

Virus Prevention in the Small/Medium Business? 89

Posted by Cliff from the keeping-out-the-nasties dept.
Morti asks: "I've been asked to select a virus scanner to be installed on the network at work. It's only a small office with six Windows XP PCs, two Linux servers and any number of Windows XP laptops that random people bring in. And I'm wondering, not just in this case but generally, what is the virus scanning / Internet security solution of choice for the small business these days? Costs need to be kept at a minimum, particularly because this business is a registered charity (a church, no less). We used to have Norton Internet Security but I'm not really keen to keep it. Besides Linux (which I've been pushing but nobody's interested), what is the most cost-effective and generally 'best' virus prevention and Internet security solution for the small/medium business?"

Are Website Performance Metrics Still Relevant? 14

Posted by Cliff from the stuff-to-discuss dept.
jackvalko asks: "Recently Keynote Systems began an upgrade of Transaction Perspective, one of their performance measuring products. The data collected is used by the Executive staff at the dotcom I work for as a means to evaluate our customer experience. Now that they are almost done, we've noticed a better than 40% reduction in response time of our site. While I'm happy that our performance 'looks' good, this major change has given us pause to question the statistical relevance of the data that is being collected and the somewhat arbitrary nature of performance metrics collection in general. And, of course, how we message all of this to upper management. So I put it to you, Slashdot! Do you find performance metrics relevant to your customer experience? How do you manage expectations and change to upper management? And, most importantly perhaps, are organizations that collect this data still relevant on The Internet as it exists today?"

Infrastructure for One Million Email Accounts? 1216

Posted by Cliff from the better-have-good-spam-filters dept.
cfsmp3 asks: "I have been asked to define the infrastructure for the email system for a huge company, which fed up of Exchange, wants to replace their entire system with something non-Microsoft. I have done this before, but not for anything of this scale. Suppose you are given a chance to build from scratch an email system that has to support around one million accounts. Some corporate, some personal, some free. POP, IMAP, webmail, etc are requirements. The system must scale perfectly, 99.9% uptime is expected... where would you start?"

Tools for Automated Grading? 100

Posted by Cliff from the tech-lightens-the-workload dept.
Dont tempt me asks: "As all teachers and students are well aware, it is back to school time. As a math/computer teacher, I am constantly looking for ways to automate repetitive tasks. The one that seems to take up most of my time is grading. As is typical for us nerds, I find myself looking at handwritten tests and thinking 'there's gotta be a better way...' Since I can't find any related open-source projects, I have been thinking about creating one. I have been toying with the idea of using OMR (Optical Mark Recognition) to make my own scannable multiple choice tests. Is anyone doing this? If not, where would be a good place to start? In addition to teachers, this could be a useful technology for questionnaires, or other processes that require manual data entry."

Smartphone Suggestions for Text SSH Use? 86

Posted by Cliff from the shells-you-can-take-with-you dept.
BinLadenMyHero asks: "The company I work for, administrating their Linux email server, wants to buy me a GSM device so I can access the server 24/7 in case of any trouble. I usually work with a text terminal session over SSH (mutt, vi, bash, screen, etc..). The Nokia 9500 looks the best for the job (640 pixels wide, and a qwerty keyboard), but is a bit large to carry everywhere. Sony Ericsson 910 is smaller, but that small screen size and keyboard can make it less useful. Treo and iPaq was also considered. Any advice on which device to buy?"

Does anyone know which brands/models would be better suited for life in the desert?"

Best Way to Port a Windows Game to Linux? 67

Posted by Cliff from the shortcuts-to-market dept.
cliffski asks: "I have a Windows game that may benefit from a port to Linux. It's a complex politics sim based on a neural network, (think NationStates with complexity) and is probably right up the street of many Linux gamers. The problem right now is that I don't have the knowledge or the time to handle a Linux port, myself. What's the best way to arrange for a commercial port of games software to the Linux platform? Is it worth talking to lone enthusiastic hackers about collaborating? Would I save myself a lot of hassle by selling the porting rights to an established Linux games company?"

Advice for the K12 Tech Guy? 96

Posted by Cliff from the a-tech-in-non-tech-friendly-waters dept.
small fish asks: "I am a newly dubbed 'Technology Coordinator' for a K-12 school district. Things here technology-wise are not well. People here are ignorant technology-wise--which is fine, as being tech-savvy is my job. However, they do not seem to trust my judgment on anything except changing printer cartridges. I'm being measured against a former teacher who filled the role for a while and was VERY comfortable with using Microsoft products. Are there any other Slashdot readers out there in similar straits? If so, what advice do you have for me?"
