waynelorentz asks: "I've finally reached a point in my life where my time with my family is more important than my money, so I've given in to my wife's persistent urging and bought a Roomba robotic vacuum. While I'm waiting for delivery, I googled for additional information about it and found there is a fledgling community of Roomba hackers outfitting their Roombas with cameras and other equipment. So, it got me wondering - what other appliances have Slashdot-types hacked? I remember when the Internet was young, there were coffee and soda machines you could ping, and the fabled Jellyjet toaster. Anything else?"

StyleChief asks: "My employer has decided to begin migrating all of the company's documentation oriented objects and files to a new content management system. The new system seems to have good functionality, robustness, and better usability than our current systems. However, the task of migrating all of the data from 2 or 3 other repositories to the new system seems to be a daunting chore. Automating the process as much as possible is of course my first goal. There are APIs that one can use to do this, but the details quickly become eye opening. Questions of objects versus files, handling their attributes, authorizations, file type identification, shadowing, build integration, versioning, etc., are several of the plethora of issues at hand. Moving perhaps hundreds of thousands of objects from one proprietary repository to another while preserving everything related to that object is the name of the game. I would like to know how others from Slashdot have dealt with similar scenarios. I am particularly interested in the 'lessons learned,' and the problems that you didn't see coming beforehand."

InOverOurHeads asks: "Some of my coworkers and I are building a new datacenter for our company. We're a growing startup, we have about 50 servers now and expect to have about twice that before too long so building to grow is key. Now that we're about $15,000 in to the project, it is looking and feeling more and more like we were way over our heads. We have 4 racks wired to a single 20amp circuit. Our UPS is at 90% load and we only have 10 machines on it. We have all of our cooling on one side of the server room where it is about 60 degrees, the other side of the room where the servers exhaust is about 30 degrees warmer, so it appears that we have some convection problems with only a handful of the machines on, right now. We're realizing that there is a lot more to building a datacenter than racking servers, what else have we missed?"

An anonymous reader writes "Gerard Beekmans has a really good comparison of the speeds of IDE and SCSI drives up over on devchannel.org. Should help put an end to the myth of IDE erasing SCSI's speed advantage." Note that Beekmans' test handicaps the SCSI disk a bit, with interesting results. (DevChannel, like Slashdot, is part of OSDN.)

Andrew Baxter writes "Ian Giblin is a senior contributing editor to bargainPDA.com for all things Linux. In his latest review Ian brings an in depth look at the YOPY YP-3700 from G.Mate, Ian informs us that "this device is geeky, and I mean Battlestar Galactica geeky" and that it is "undoubtedly the most linuxy handheld device I've seen. It out-linuxes the Sharp Zaurus range." Read on for many pictures, device specs and in depth information on this Linux PDA device now available in the U.S. and also South Korea."

Alan writes "What's the best platform for playing games *and* doing work? That's the very question FiringSquad tries to answer in the sequel to last year's short but popular workstation building article. This time, they've went with a "no-budget, but don't waste money" approach. There are a dozen products reviewed in the article, some never before reviewed on the 'net, and this time, there's no system building detail left untouched. Discussed are AC line conditioners, 2D graphics performance, and more. This more than 12,000 word article is the most detailed article ever in its genre. "

penciling_in writes "John Patrick, former vice president of Internet technology at IBM, says 'ENUM is a really big deal'. Here is what he has to say on CircleID about this: 'Basically, ENUM is a protocol that will make it possible to converge the Public Switched Telephone Network (PSTN) and the Internet. In other words, a telephone number can get you to a Web service -- telephone number in, URL out. The idea can be extremely useful when you consider that most telephones are limited to twelve keys on a keypad. Every try to enter your alphanumeric login ID and password to a web site on a cell phone or Personal Digital Assistant? It is next to impossible! The biggest impact of ENUM will probably be for Voice Over IP (VoIP). In fact, it could be the tipping point.'"

prostoalex writes "Federal Communications Commission opened up 90 MHz of previously reserved bandwidth for next-generation wireless services. The FCC news release (MS Word, PDF, apparently no HTML) specifies the following ranges to be available for commercial exploitation: 1710-1755 MHz and 2110-2155 MHz. Currently the licenses are issued to the business capable of providing "substantial service by the end of the license term", later on the licenses will be sold to the highest bidder. There's also this announcement about millimeter wave broadband frequencies."

Anonymous Howard writes "For those of you who haven't heard about Panasonic's Toughbook W2, this hard to find laptop not only looks awesome but packs a serious punch for its size. Weighing in at 2.8 pounds with a 12.1" screen, this P4-M 900 Centrino based laptop is impressive. The drawback is its max memory support is only 512MB. However I think the laptop is absolutely gorgeous. Does anyone have any experience with one of these? Designtechnica gave it a 7 in their review. I tend to believe that 512MB of ram is a pretty limiting factor however."

agentk writes "The Boston Globe reports today that area supermarket Stop & Shop is adding computers with Bluetooth barcode scanners, 802.11 networking and infrared positional sensors to shopping carts in one of its stores. 'The Shopping Buddy automatically displays which aisle you're in, what's on sale there, and what you bought the last time you strolled through.' Most Stop & Shop stores already have automated self-checkout lanes. Is this the future of shopping? What will the impact be on privacy, the cash economy, and the experience of shopping in general?"

Roland Piquepaille writes "In 'Human Body Network Gets Fast,' Technology Research News tells us that NTT Docomo researchers in Japan have created a 10-Mbit/second indoor network by using human bodies as Ethernet cables. 'The network, dubbed ElectAura-Net, is wireless, but instead of using radio waves, infrared light, or microwaves to transmit information it uses a combination of the electric field that emanates from humans and a similar field emanating from special floor tiles.' ElectAura-Net is faster than the Bluetooth radio wave system and provides a solution for indoor networks. The researchers think that this is a solution for "ubiquitous" communication, using GPS outdoor and our bodies indoor. This summary contains more details."

An anonymous reader writes "This interview at WindowsForDevices is with a young Russian programmer who earlier this year launched a project to port the open source GCC C/C++ compiler and supporting tools (library, manager, linker, etc.) to Windows CE and the Pocket PC platform. The result, according to Vitaliy Pronkin, the project's founder, is that it is now possible to develop applications directly on a Pocket PC PDA using the standard C/C++ programming language. Specifically, source code written in eVC (MFC isn't supported yet) can be built and then executed directly on the Pocket PC (or other Windows CE device) without conversion or additional runtimes. Find it, fix it, compile it, run it -- right on your Pocket PC!"

Weston writes "CNet has posted an article about WinFS, or more specifically, what Bob Muglia (a VP at Microsoft) said about it in a recent interview. According to Muglia, the new filesystem will not replace NTFS, but will incorporate feratures of NTFS, SQL, and XML all into a filesystem which, accoring to Microsoft, will open up a whole new world of information availability. He goes on to describe such a filesystem as the 'holy grail' that is sought by developers. WinFS is slated for release in 2005/06 as part of the Longhorn OS."

man_ls asks: "I have recently run across the need for a network print server appliance, that can spool the data it is given and send it slower than 10 mbps to the printer. A client of mine has an Intermec label printer, with an internal processor too slow to accept data directly from the network without being buffered. Due to the system the client is running (OpenVMS) it must be connected to the network, it can't be local on one of the servers. Any ideas of a small print server box that can act like a spooler?"
