Comment RAID6 with enterprise hardware is reliable (Score 2, Interesting) 444

I use RAID6 for several high-volume machines at work. Having double parity plus a hot spare means rebuild time is no worry.

But if you are not a fan you can always throw something together with ZFS's RAIDZ or RAIDZ2 which is also distributed parity but the ZFS filesystem checksums and keeps multiple (distributed) copies of every block to detect and fix data corruption before it becomes a bigger problem.

People using ZFS have been able to detect silent data corruption from a faulty power supply that other solutions would never have found just because of the checksumming process.

Yeah from some of the stories I have been following on this, it seems some firms even co-locate their machines in the same room with the NYSE trade systems. I imagine that could be quite an advantage over other traders, especially when coupled with some extremely high performance program trade code like Goldman Sachs has been using.

The Raptors are already irrelevant. According to this article in the LA Times (http://www.latimes.com/news/nationworld/nation/la-na-f-22-plane22-2009jul22,0,750816.story) they have NOT been used in Iraq or Afghanistan.

All the fighter jets in the world won't win a guerilla war against insurgent enemies.

What is going on now is our military is finally realizing this - the big obstacle to a more nimble military is not the military itself, but the massive multi-billion dollar military industrial complex that refuses to get weened off the teet.

Palm Announces Killer New Phone 617

Barence writes "At CES, Palm announced what promises to be the product that finally matches and even betters the Apple iPhone, and certainly looks to be the most important product announced at this year's Consumer Electronics Show. It's called the Palm Pre and it's based on a completely new operating system, called Palm webOS. Its key specs include a 3.1in 320x 480 touchscreen, 8GB of storage, UMTS HDSPA support (in the UK version of the phone), 802.11b/g WLAN, Bluetooth, and GPS. It also includes a slide-out Qwerty keyboard, 3.5mm headphone jack, and what Palm described as the 'fastest ever' Texas Instruments OMAP processor."

Comment I use everyone.net (Score 1) 601

I use a service called everyone.net - allows me to have my own domain name, they support both IMAP (my preference) as well as POP.

They also support secure IMAP/POP/etc. over SSL.

Good service overall and have not had any problems over the last 2.5 years or so that I have been using them.

Submission + - FCC Relaxed Media Ownership, ignores public (nytimes.com)

anthrax writes: "Completely ignoring Congress and public comments, the FCC voted to relax ownership rules which prevented broadcasters from owning newspapers in the nation's 20 largest media markets. After holding several public hearings that overwhelmingly opposed the relaxation or the rules, and Congressional hearing where Democratic and Republican (even Ted "The Internet is Tubes" Stevens) voiced opposition to the move, the FCC voted 3 to 2 to change the rules. Not hard guessing the political affiliation of the votes."

An anonymous reader writes: BusinessWeek has an article up on Verizon deciding to support Android. After passing on the iPhone and initially missing the Anroid boat, now Verizon says they're going to open their network to more devices, move their network to GSM-based radio technology (LTE), and now support Anroid. Is Verizon actually trying to become less evil or is this all for the press?
Wine

Submission + - OS X Leopard now can natively load Windows Files.

Steven Edwards writes: "PE Files were rejected on Tiger but now can be loaded natively on Leopard, which is interesting to me because I don't think that this is just a hold over from EFI support because the behavior is new. I think it may be a sign of future addition of a Win32 subsystem to OS X. Check the following URLs for the detailed technical information.

I think this behavior may be a sign of a future addition of a Win32 subsystem to OS X. I think the powers that be at apple have decided that they are missing the pie that Parallels, VMware and CodeWeavers are getting. If you combine the value of all three products, I expect its adding up to a good chunk of change they view as "lost" every month. Having a system like Wine that runs in a clunky Classic like mode would mean better user tie-in than having to reboot with BootCamp."

Submission + - Mythbusters to test cockroaches radiation myth (tri-cityherald.com)

redwoodtree writes: "As the article quotes so perfectly "Contrary to popular belief, not a significant amount of research goes into cockroach radiation" so the Mythbusters are going out to Hanford Site where plutonium was manufactured for the first nuclear bomb. It's the single most polluted nuclear waste site in the U.S. The Mythbusters are going to take cockroaches and other insects and apply successively higher doses of radiation in a controlled setting. One group of insects will not be exposed to any radiation of course. It turns out that the facility is used to test radiation on electronic equipment, power lines and so forth. It's comforting that all the nuclear waste is being put to some good use before it all washes down into the Columbia river."

Submission + - Outsourced, anonymous voter suppression calls (cnet.com)

An anonymous reader writes: On election day 2002, computerized hang-up calls orchestrated by the Republican Party jammed phone lines set up by the New Hampshire Democratic Party and the Manchester firefighters' union. The 2004 and 2006 elections saw similar shenanigans, leading to a FBI investigation of voter suppression calls in Virginia. A recent CNET editorial explores some scary future scenarios where political parties have outsourced their dirty-tricks to offshore companies in India and the Philippines. The main result of this, is that as phishers have already discovered, putting 8 thousand miles between the criminal and their victim can make investigation and prosecution next to impossible.
Microsoft

Submission + - Microsoft must abandon Vista to save itself (neowin.net)

Technical Writing Geek writes: "While Vista was originally touted by Microsoft as the operating system savior we've all been waiting for, it has turned out to be one of the biggest blunders in technology. With a host of issues that are inexcusable and features that are taken from the Mac OS X and Linux playbook, Microsoft has once again lost sight of what we really want.

As we're more than aware, Vista Ultimate comes at a premium. For an additional $160 over the Premium SKU price, Ultimate gives you a complete backup and restore option, BitLocker Drive encryption, the ever so popular Windows Fax & Scan, and the "Ultimate Extras." But what started with a promise of "Extras" by summer, quickly turned into an apology from Microsoft and the eventual release of DreamScene and Windows Hold 'Em (among others) today. And while each of the "Extras" runs just fine, Microsoft's "Extras" blunder is just another reason why the company must abandon Vista before it's too late.

An example of the changes:
