Is Zigbee the Next Bluetooth? 66

Posted by Cliff from the rise-or-fall-of-another-wireless-technology dept.
bz asks: "I work for a small product development company that is considering the use of RF. Naturally, it seems that it would be easier to use a proprietary protocol rather than some of the standards on the market. We are restricted by small code space and low power. The Zigbee protocol needs more memory than we would like to give up. Naturally, if Zigbee is going to become ubiquitous, we would like to sacrifice the extra memory and jump on the bandwagon. However, if it is only going to be as popular as Bluetooth, we would prefer to pass. Is Zigbee going to succeed, or is it likely to follow along the low road that Bluetooth has already paved?"

Linux Desktop Deployment Postmortems? 371

Posted by Cliff from the how-well-did-it-do? dept.
duffbeer703 asks: "My employer runs alot of desktop and laptop computers -- something in the neighborhood of 40,000 PCs. Currently they are all Windows 2000 & XP managed by Active Directory and other big, complicated enterprise management tools, all of which can support Linux in one form or another. I'm looking for ways of making Linux (and maybe Unix or even Apple desktops) an option as we replace or add PCs. The problem is, most of the resources that you find online about deploying Linux focuses on server environment, and the articles that I do find about desktop Linux focus on standalone developer workstations, the IBM conversion to Linux (which doesn't seem to have happened) or things like LTSP, that won't integrate well with our infrastructure. Is anyone out there successfully using Linux for regular users? How did it go, and how did your IT and user communities adapt to the new kid on the block?"

Innovative Christmas Light Setups? 36

Posted by Cliff from the envy-of-the-neighborhood dept.
glitch0 asks: "Recently, I found some pretty neat Christmas decorations, at a neighbors house. He has a light setup that syncs up with MIDI files of Christmas music. The cool part is the way you hear the music - it's broadcast using a radio transmitter so you can tune your car radio as you're driving by and hear and see the show. Do any other Slashdot readers have cool homebrew light setups or ideas for over-the-top holiday decorations?"

What Makes a Good IM Client? 649

Posted by Cliff from the no-skimping-on-the-features dept.
thesaint05 asks: "So I was sitting here at my job where and IM is a pretty integral part of communicating intra-office. However, I have 3 different clients installed, and each has a different user base. Within the office we have an SIP server and use Windows Messenger. The Google Talk client is for colleagues and friends on the cutting edge, and AIM is used by pretty much everybody else (including a bunch of clients). So, after holding 3 different conversations simultaneously on all 3 clients (Windows Messenger with a colleague, AIM with my girlfriend, and Google Talk with a friend at a different tech company) I got to wondering, what are the strengths and weaknesses of all of these clients? Which do you use and why? If you could combine features from all of the IM clients out there, what would they be?"

Dealing w/ Massively Multiplying Power Cables? 85

Posted by Cliff from the breeding-like-rabbits dept.
Darius Jedburgh asks: "Wireless networking is all very well but network cables make up only a small proportion of the cables in my house. When I come home ,I plug in my GBA Micro, PowerBook, Palm, cellphone and iPod to recharge alongside camera, and other devices. Meanwhile I have power adapters for PCs, routers, access points, cable modems, monitors and external hard drives. Every time I buy a new gadget there's another cable (or two) to install. How do people keep this proliferation under control? Are there any products available to help to organize and ease the distribution of power at home? Does anyone know of novel ideas in power distribution in current development that might make things easier in the future?"

A Book on General Image Editing Concepts? 51

Posted by Cliff from the a-firm-grounding-in-the-basic-concepts dept.
halftrack asks: "Someone I know wanted 'Photoshop for Dummies' for Christmas because she wanted to learn how to use it properly (who hasn't struggled trying to draw a simple line?) However, having a strong disliking for any sort of vendor lock-in I went searching for a book that would teach image editing without tying it too strongly to Photoshop (or Gimp for that matter). However, all my searches turned out blank. Thus I was wondering if there exists such a book, or is the field too diverse? The ideal would be a (thick) book that would cover the basic concepts (layers, paths, selections, channels etc.,) before presenting how these concepts are implemented in different applications. Such a book should provide the reader with a portable skill-set and give her/him the ability to objectively choose the right tool for the job, at the right cost. Does this book exist?"

Solutions for Small Business VoIP? 232

Posted by Cliff from the from-copper-to-network dept.
MajorBlunder asks: "I'm part of the IT department of a small but prospering software company. We have recently filled the capacity of the POTS PBX phone system we currently have installed. We are currently looking into switching over to a VoIP phone system. We have a sizable IT staff in proportion to the rest of the company, so we'd like to be able to maintain the hardware/software in house as much as possible. I wanted to ask the Slashdot readership what experiences they have had with switching over to from POTS to VoIP. Any recomendations for full end to end solutions would be appreciated, and recomendations of things to avoid would be great."

Video Multiplexing on Large Screens? 29

Posted by Cliff from the items-for-the-ultimate-sports-bar dept.
videoPIP asks: "I recently finished putting together my home theater (including a projector). As I sit there and watch stuff on the big screen, I remember a time back in college where my housemates and I would have 2 or 3 TVs crammed into the entertainment center, one usually having a football game on and the other playing movies or for video games. This got me to thinking - I know that, for CCTV security systems, they have 4 screens visible at a time, but they are usually black and white (like at Best Buy). I've looked on Google for these, and there are all sorts of configurations (4/9/16 channels), (simplex/duplex,triplex). I was wondering if anyone has married one of these multiplexers with a projector, or even a very large TV to get the ultimate Picture-in-Picture experience?"

Science Fiction Stories for Teenage Girls? 161

Sooner Boomer asks: "Not having met 'Mrs. Boomer' yet, I'm buying Christmas gifts for my nieces and nephews. Whether genetics or just good luck, almost all of the young 'uns are girls. I've been slowly introducing them to the classics of science fiction: Heinlein ('Podkayne of Mars', _'Starship Troopers', etc.), Asimov short stories, Ann McAffrey (the Dragonrider books), Alan Dean Foster (the Flynx books and others), Douglas Adams and Terry Prachett, some Neil Gaiman (Stardust, Good Omens), as well as the mandatory Tolkien and C.S. Lewis. This is just a partial list, but what would Slashdot consider to be good (or even essential) science fiction for teen and pre-teen girls?"

Testing Different Mail Server Configurations? 35

Posted by Cliff from the creative-mail-routing dept.
bsaxon asks: "I am looking for advice on methods that would allow the testing and debugging of different mail server configurations, particularly different ways of handling spam and mail filtering. What are different ways that different mail configurations can be tested? Currently, we have two servers running Linux that check all incoming/outgoing mail for viruses and spam, using software that works with Sendmail. After incoming mail is processed, it is relayed to its final destination, in a mailbox on a MS Exchange server. One server handles the actual processing of mail, and the other server just queues mail when the other server is down or overworked. Basically, I would like to have all mail duplicated, before reaching any filters or virus scanners or blocklists, with one copy continuing its normal route to the production server and the other copy of the message going to the test mail server. Can it be done at the DNS level or through Sendmail or are there other ways that this could be achieved? I am only looking for suggestions that deal with different methods of testing different mail server configurations, not actual suggestions for filtering mail."

Pros and Cons of Garbage Collection? 243

Posted by Cliff from the how-would-you-prefer-to-allocate-YOUR-memory dept.
ers asks: "Most new programming languages are using garbage collection, rather than programmer-controlled memory management. The advantages are obvious: programmers no longer have to worry about forgetting to delete allocated memory, leading to far fewer memory leaks. The disadvantages are often glossed over by programming language designers - aside from the performance issues, predictable memory management can be used for controlling access to files and similar resources, creating safer thread locking code and even providing better error messages. Some programming languages, which usually predictable memory management, can also be made to behave like they are garbage collected - for example, Boost provides various C++ smart pointer classes. So, given the choice between garbage collection or manual memory management, which would you choose and why? When using a manual memory management language, when do you consider the performance and syntactic overhead of faked garbage collection to be worthwhile?"

The Funniest Places for Hardware Stickers? 146

Posted by Cliff from the mischievous-locations dept.
Nice2Cats asks: "So after buying another piece of computer hardware, I am stuck with more of those stickers that some silly person in marketing actually thinks I'm going to slap on my computer. The problem is, I'm running out of other places to put then (throwing them away would show a lack of creativity, and is out of the question). I already have one on my drill ('Sound by Hercules') and my table saw is 'Dual BIOS'; I also probably have the world's only vacuum sweeper and lawn mower that claim to be made by Apple. I don't want the stuff on my car, my wife draws the line at our toilet cover -- where have other Slashdot readers put these stickers? Where is the most awesome place you have seen, say, that white Apple?"

Time Saving Linux Desktop Tips? 565

Posted by Cliff from the a-more-comfortable-GUI-experience dept.
dan_polt asks: "I currently use a Linux desktop system, at work. One of the great things about the Linux desktop is that there are lots of ways to save a lot of time from useful widgets and configuration to minimize the pain of repetitive tasks. Most of my work involves web/e-Mail/SSH access, and I have a very high spec'd machine with dual-head 1600x1200 screens. What software or configuration tips might Slashdot have for me to: make better use of my time; make the most of my screen real estate; and make my use of the desktop more effective?"

Fix Your Crashing X-Box 360 With String 686

Posted by CmdrTaco from the at-least-you-have-one dept.
mkraft writes "A gamer fed up with his new Xbox 360 crashing every 20 minutes has fixed the problem by raising the power supply off the ground with some string. Goldeneyemaster over at the GameSpot forums indicates that the main reason for his Xbox 360 freezing up is the power supply overheating. The solution is to lift the power supply off the floor and allow the air to circulate better around it."

Smart Mouse with E-Mail and IM Alerts 225

Posted by CmdrTaco from the who-is-looking-at-their-mouse dept.
lilrock writes "CoolTechZone.com takes a look at the world's first smart mouse from Logitech, the MX610, that has e-mail and IM alert buttons. It also has auto turn on/off functionality as well. According to the article, 'All these standard features aside, what has us impressed are the e-mail and IM notification buttons. Though the idea behind them is simple, it's interesting how Logitech comes up with such exclusive features. Basically, you will have to configure the indicators to alert you when you receive an e-mail and/or an IM message from the person of your choice. The buttons will alert you by lighting up, and lead you directly to the message once you press them.' " Because I for one am constantly staring at my mouse when I have a gigantic monitor right in front of me. Cough.
