No, i'm not doing it wrong.

There's no business requirement for us to failover in 5 seconds, or 5 minutes for that matter; so long as we can continue business in an hour we will get by; people do have pens and paper to keep things running.

I'm currently unengineering a predecessors stupid decision to put an Enterprise DB cluster in place, one that costs us around 20% of our cash flow, we can't afford to upgrade and gives the HA levels we do not need.

Comment SQL Server experience (Score 2) 284

I recently inherited an application built on .NET, we're a Linux organisation. The devs had typically built it on SQL Server Express with not a care in the world, but it was a core business app.

We bought a single license of SQL Server standard, and put it in Master Slave replication mode. Not having touched Windows for years (as a server) it was a bit of faff to get an Active Directory setup going, but it actually works okay. You don't need to license the failover server for SQL Server.

If there's a failure, it's about 10 minutes on notification to flip the servers over and a bit of manual intervention. You can cut this down by buying a third box to use as an observer, but that seems to be another SPF.

I went to see Avatar at the local IMAX in 3D, and had to leave the movie halfway through with a massive headache. My eyesight is basically okay, but I just couldn't relax and watch the focal point the director insisted you watch - rather my cognition is rather pan and scan, I was constantly looking around the scene and kept on hitting things that I couldn't focus on and strained my eyes trying to compensate.

You are right, eSATA is better - it's what we are using. The cradle is an eSATA/USB hybrid & the controller is a LaCie eSATA PCI card (only one we could find at reasonable prices with win2k3 drivers)

There's not much need for using something like BartPE on Vista/7 really - you just right click drag folders from drive to drive.

I'm doing this already, it works bloody well. I have my OS and Programs installed on a 120GB SSD, which sits around 50% utilisation and use NTFS junctions (aka symlinks) to map storage for stuff that doesn't need superfast seek speed (aka data) onto a group of 1.5TB drives. It takes a little management, so isn't quite ready for the average user yet - but you do effectively get something like 5TB of online disk space combined with SSD performance.

Interestingly, i've found on Windows 7 that by running OS/Programs from the SSD that the contention issues you would normally get on a spinning disk are mitigated a great deal - and there's no noticeable hit with having the entire user profile (including junk like web cache). The system is booted in 5 seconds after finishing its POST, and the desktop is snappy right from the get go.

As to the hard disks as backup, it works pretty good. At work we have maybe 1.2TB in a full backup - we do a weekly full backup and incrementals onto LTO tapes, and a second weekly backup onto a consumer grade SATA 1.5TB drive in a USB cradle. The SATA drives are taken offsite in case the office burns down, £80 + carrying a few hundred grams around makes for really cheap and fast data transfer.

DX11 Tested Against DX9 With Dirt 2 Demo 201

MojoKid writes "The PC demo for Codemasters' upcoming DirectX 11 racing title, Dirt 2, has just hit the web and is available for download. Dirt 2 is a highly-anticipated racing sim that also happens to feature leading-edge graphic effects. In addition to a DirectX 9 code path, Dirt 2 also utilizes a number of DirectX 11 features, like hardware-tessellated dynamic water, an animated crowd and dynamic cloth effects, in addition to DirectCompute 11-accelerated high-definition ambient occlusion (HADO), full floating-point high dynamic range (HDR) lighting, and full-screen resolution post processing. Performance-wise, DX11 didn't take its toll as much as you'd expect this early on in its adoption cycle." Bit-tech also took a look at the graphical differences, arriving at this conclusion: "You'd need a seriously keen eye and brown paper envelope full of cash from one of the creators of Dirt 2 to notice any real difference between textures in the two versions of DirectX."

Scientists Deliver Bee Toxin To Tumors Via "Nanobees" 98

ScienceDaily is reporting that Washington University School of Medicine researchers have found a way to deliver bee toxin to tumors using nano-spheres they call "nanobees." The results in mice showed a cessation of growth or even shrinkage of tumors while the surrounding tissue was protected from the toxin. "The core of the nanobees is composed of perfluorocarbon, an inert compound used in artificial blood. The research group developed perfluorocarbon nanoparticles several years ago and have been studying their use in various medical applications, including diagnosis and treatment of atherosclerosis and cancer. About six millionths of an inch in diameter, the nanoparticles are large enough to carry thousands of active compounds, yet small enough to pass readily through the bloodstream and to attach to cell membranes."

OS Performance — Snow Leopard, Windows 7, and Ubuntu 9.10 688

BeckySharp writes "With the nearly simultaneous release of Apple's Mac OS X 10.6 'Snow Leopard' (available right now) and Microsoft's Windows 7 (available Oct. 22), you get the inevitable debate: Which is the better operating system, Windows 7 or Snow Leopard? To help determine that, Computerworld's Preston Gralla put both operating systems through their paces, selected categories for a head-to-head competition, and then chose a winner in each category." Relatedly, Phoronix has posted Snow Leopard vs. Ubuntu 9.10 benchmarks. They ran tests from ray tracing to 3D gaming to compilation. Their tests show Ubuntu 9.10 winning a number of the tests, but there are some slowdowns in performance and still multiple wins in favor of Snow Leopard, so the end result is mixed.

Military Helmet Design Contributes To Brain Damage 294

BuzzSkyline writes "Improvements in helmets have helped modern soldiers survive bullets and blasts that would have killed them in past wars. But increasing numbers of soldiers are suffering long lasting brain damage from explosions, partly as a result of what appears to be a flaw in helmet designs. Although the blast itself may not accelerate the brain inside a soldier's head enough to cause injury, shockwaves that make it through the space between a helmet and a soldier's head can cause the skull to flex, leading to ripples in the skull that can create damaging pressures in the brain. Simulations that relied on 'code originally designed to simulate how a detonated weapon rattles a building or tank' could lead to new helmets that reduce the traumatic brain injuries that many soldiers suffer as a result of improvised explosive devices and other moderate-sized blasts. The research is due to be published in Physical Review Letters, but a pre-print of the entire article is currently available on the Physics ArXiv."
