XFS Merged into Linux 2.4 265

Posted by CmdrTaco from the journals-are-for-girls dept.
Alphix writes "As noted on KernelTrap Marcelo has merged XFS into 2.4 after a code review by Christoph Hellwig. The mail from Marcelo on LKML is here. Apparently it touched very little VFS code so people not using XFS shouldn't see any ill effects from this (it's even supposed to fix some VFS bugs). XFS is described by SGI as '...a journalling filesystem developed by SGI and used in SGI's IRIX operating system. It is now also available under GPL for linux. It is extremely scalable, using btrees extensively to support large and/or sparse files, and extremely large directories. The journalling capability means no more waiting for fsck's or worrying about meta-data corruption.' Let the stability vs. new-features flamewar begin."

Easy to use Household Temperature Monitor? 106

Posted by Cliff from the creating-a-better-thermostat dept.
Jim Carroll asks: "I awoke this morning to a gas furnace that conked out. The house was 60F. We had to turn the switch off and on to get it working again. Fair enough -- but I'm worried about it going off when I'm travelling and having the pipes freeze. I'm looking for an inexpensive, simple to use temperature monitor/sensor that would plug into a USB port, that would then log household temperature to a server, so that I can view it through my broadband connection while travelling. Sure, there are all kinds of complex X10 solutions; there seems to be a few kits out there; and some high end industrial applications, but these all involve spending a few hundred dollars. I want simple, straightforward, cheap -- plug it in, and it dumps the temp every few minutes to a file. But there doesn't seem to be anything that is simple, $10-20, that is consumer oriented? And if not, why aren't companies yet making this type of device?"

Australian Researchers Push Near-Broadband IP Over VHF 211

Posted by timothy from the verified-horse-feathers dept.
Curmudgeon Rick writes "A research group at the Australian National University is getting symmetrical 250K bps at 20km, using "empty" 7MHz-wide broadcast TV allocations in the 45MHz band. Story here, project homepage here. Aim is to put some bandwidth out beyond the reach of the wires, where users are few and far between."

Considerations When Accepting Bandwidth Donations? 24

Posted by Cliff from the what-should-one-worry-about dept.
dnotj asks: "I'm involved in a project that is growing fast and is going to soon outgrow it's current hosting location. I've had a couple of offers for donating bandwidth (and servers in one case). Basically free colocation or dedicated servers. Since this isn't a revenue generating project, it's going to be necessary to migrate this project and it's related website to a location with adequate bandwidth. What kinds of questions should I be asking these generous organizations that make these offers? I just want to make sure I cover all my bases before jumping on one of these offers."

Cheap On-Line CD/DVD Storage Library? 106

Posted by Cliff from the isn't-there-a-market-for-this dept.
ngoy asks: "I download gigabytes of stuff from Usenet and burn it onto CD's (and soon DVD's). I have countless numbers of spindles filled with apps, games, MP3's, and so forth. Does anyone know of a cheap (sub $400) storage library that can hold 300 CD's or more and is smaller than the refrigerator sized libraries of day's old? I know Pioneer used to make a 6 disc CD-ROM changer, based on their car stereo, but that is the largest I have seen for quite a while. Googling for jukeboxes gives me a range of prices starting at $2000 to $6000 on up. Sony makes consumer DVD players that have 300 and 400 disc capacities for $500 and $400, why is there not something similar for computers? If you stripped out the A/V stuff from the Sony, you should save another $50 to $100, so theoretically I should be able to buy a changer for around $300. Isn't there a market for such devices?"

Open Source Finally Hits Real Silicon 247

Posted by timothy from the mask-of-progress dept.
pagercam2 writes "While Open Source software has many success stories, hardware and particularly chips haven't had as much. While there have been multiple Open Source projects, none have come to a final product until now. The OpenRISC 1000 has been implemented by Flextronics Semiconductor(a division of Flextronics, the contract manufacturer possibly best known for its production of many Cisco products) along with PCI, 10/100 Ethernet, serial, GPIO etc. ... Details and pretty pictures available at OpenCores.org, and it even runs uClinux. Good Job!"

Finding Holiday Discounts on iPods? 849

Posted by Cliff from the getting-a-hold-of-a-real-bargain dept.
jeffy124 asks: "I was hoping to get an Apple iPod for Christmas. Alas, it's too expensive and out of the budget. So I'm forced into purchasing it for myself. Hoping to cash in on a holiday season bargain, I've been keeping my eye on the sales circulars that come in the newspaper. I've seen plenty of discounts for MP3 players of all kinds (Rio's, Dell's new HD-based player, etc), and the iPod has also shown up. Christmas does not yet seem very merry to me. They're always at the regular $299/399/499 price, never at a discount of any sort. You read that right, it's 'for sale' at the *regular* price. Stores guilty of this include Best Buy, Circuit City, Target, and CompUSA. Why do stores do this? How often? And does anyone know why Apple has been singled out while their competition has gotten their products discounted? Anyone know who *is* granting discounts on iPods this holiday season?"

We're Jammin', Hope You Like Jammin' Too 422

Posted by CowboyNeal from the peace-and-quiet-devices dept.
theodp writes "Slate ponders whether a climate where anything can be photographed or surreptitiously recorded means the once-esoteric world of cell-phone jamming will become mainstream. Sites now offer portable cell-phone jammers that can provide you with the same kind of security bubbles used to thwart industrial spies, hostage-takers and bomb detonators. While actively jamming a cell-phone signal is illegal in the US, a distributor reports most of his sales go to US customers, including universities which use the technology to stop students from diddling away on phones during lectures."

New Low Cost DVD Burners Hit The Streets 273

Posted by CowboyNeal from the budget-disc-creation dept.
SpinnerBait writes "DVD burners, until recently, have been a bit too pricey for the average consumer that just wants to backup large amounts of data or rescue a failing DVD movie disc. However, OEMs like AOpen have finally broken the $100 price point, as this article and performance analysis at HotHardware reports. Performance, for this sub $100 DVD burner was respectable as well, burning almost an entire DVD's worth of data in about 15 minutes. Not too shabby at all... just in time for the holidays."

AT&T Wireless Fumbles Number Portability 309

Posted by michael from the short-bus dept.
cloudscout writes "The FCC is demanding that AT&T Wireless Services explain their number portability failures. Apparently, tens of thousands of customers are having their number portability requests delayed because of computer system problems at AT&T Wireless. Sadly, the FCC did not say they were going to be imposing fines for this breach of regulations yet but I'm sure that will follow if things don't improve quickly." Reader (54)T-Dub adds: "As many of you already reported on wed, there have been some pretty serious delays for people switching cellphone providers according to this NYTimes article (free reg required). Most notably former AT&T customers can expect to wait up to a week for their number to switch."

ViewSonic AirPanel v150 Review at Ars Technica 139

Posted by michael from the straight-dope dept.
Haxby writes "Ars Technica has a pretty thorough review of the ViewSonic AirPanel (15 inch model). You might recall that this device/design won 'Best of Comdex' in 2002, but as the review clearly shows, it's not really all that great, and it's way overpriced. The biggest problem is video performance: it sucks. Poor resolution and hideous rendering times (partly Microsoft's RDC's fault) make it next to useless. Is more bandwidth the key to making these things more palatable?"

"Budget" Chips go Head-to-Head 372

Posted by CowboyNeal from the duking-it-out dept.
StewedSquirrel writes "Anandtech has published an article taking a look at the low-end of the CPU market today. It takes Intel's newest Celeron processors against the AthlonXP and Duron with a Pentium 4 1.8GHz thrown in for comparison. All of these processors will cost you under $120, but the article shows that the old Duron (at barely $40) can out-perform Intel chips costing nearly 3x as much. In addition, it shows that the performance of the Athlon XP is head and shoulders above the Celeron processors, while costing roughly the same."

AOL's $299 PC 367

Posted by CowboyNeal from the pablum-for-the-masses dept.
cmj writes "Internet.com reports 'Looking to attract households that still aren't online, AOL is offering new customers a $299 PC system if they sign a one-year $23.90 dial-up Internet service contract.' A click through AOL's ecommerce site reveals the the specs as 1.7 GHz Celeron with 256 MB RAM, 40 GB hard drive, 56K modem, 10/100ethernet card, 17" monitor and Lexmark printer. The PC is running Windows XP, and includes 'AOL Office Powered by Sun'. Also of note is the fact that the $299 appears to be financed at around 22%. The math ( (12*23.90)+299 ) seems to suggest that you can get a $699 computer for $585.80 plus any finance charges. Setting aside the question of whether this is a good deal or not, one has to wonder whether AOL is desperate for new customers and resorting to bribery, or just progressing to the next step of branding. With this action AOL controls everything from the OS to the Word Processor to the web sites their customers browse."

Voting Machines Vs. Slot Machines 299

Posted by michael from the we-know-what's-truly-important dept.
dmh20002 writes "Being a Nevada resident and knowing people who write code for slot machines, I was aware of the stringent measures the state of Nevada uses to vet the security of slot machines. The Nevada Gaming Control Board audits everything about them, both physical and soft, for unintentional and intentional security holes. Hearing the hoopla on voting machines, the contrast was obvious. Slot machines are about money, which is more important than votes, apparently. Now the state of Nevada is looking at electronic voting machines and plan to apply some of the same safeguards. Just applying the Nevada technical standards for gaming machines and vendors to voting machines would be a start, since there don't seem to be any standards for voting machines. A funny/sad sideline is that in Nevada, every year or two a programmer or engineer goes to jail for exploiting slot machines."

Preventing Shutdown on Active NFS Servers? 66

Posted by Cliff from the disconnect-your-shares,-first dept.
Ed Almos asks: "Like many Slashdot Readers, I run a small network at home with a server and a number of desktops. The server holds all our files as NFS shares and doubles as a desktop machine should the need arise. Problems however occur if the server is shut down whilst there are NFS shares in use, the minimum disruption is a crashed desktop and a couple of times I have had to deal with corrupted files. Does anyone know of a way to prevent shutdown of a machine if someone else has drives mounted to its NFS shares ? I have already explored use of the /etc/shutdown.allow file but all this does is determine who can kill the machine. The minimal solution would be something similar to a Microsoft Windows system, where a request to shutdown brings up a warning window that there are users connected to the system, but I am not sure how to achieve this on a Linux system. Ideally I would like to prevent shutdown of a system with active NFS shares altogether, or at least until the user has unmounted and logged off the network."

What's the Hardiest Hardware You've Seen? 247

Posted by Cliff from the survivor:-hardware dept.
mrsev asks: "I work in a lab and so have lots of strange equipment around me. Recently I found an old 256Mb USB Flash Disk, that I had been looking for 6 months. This would not be amazing but for the fact that it was frozen in a block of ice in one of our -80C freezers (-112F). It must have fallen from my top pocket when I was reaching in. After chiping it out and a quick thaw and dry ... it worked!! All my data was intact and there were no problems. I am now looking for a victim to test in our liquid nitrogen storage facility. My question is what is the strangest hardware survival you have seen."

CD-ROMs Failing In Win2k & XP Boxes? 116

Posted by timothy from the knoppix-time dept.
jptechnical writes "I have an interesting hardware/software development brewing. I have a friend with a computer shop down the way and he has had a rash of nearly a dozen Win2k & XP boxes come through with disabled or missing CD-ROM drives. They work in DOS, and are bootable, but are either disabled, not functioning or simply missing in Windows' device manager. Does anyone know of a virus that may be causing this? I cannot find any common vector from system build to software installed or anything. MS says reformat, but where's the fun in that? What resources aside from MSKB and google searching do slashdot readers use for troubleshooting strange problems?"
