Submission + - How do I convince them Virtual is NOT best?

An anonymous reader writes: I work as 3rd line support for an application vendor, from time to time we get some really out-there issues reported by our customers. Usually it's data, or user error, but from time to time its a performance issue with our 'legacy' code.

Our internal IT dept are racing to do an entire VMware infrastructure. I realise the benefits from a 'Production' point of view, but I don't need all those benefits. I NEED to replicate the deployment of our software in the same environment many of our customers still run it. On 'old' physical kit.

The IT team claim they can dial down the VM server to behave the same as a physical host would, but our first pass of testing showed faster performance on the VM (by several orders of magnitute!). But they claim they can dial it down even further...To match the results of our physical server.

I say thats 'not fair' as the architecture between a current generation server hosting a VM is so vastly different to a 5 year old phyiscal host that it becomes a nonsense.

They wont hear it.. What's the killer arguement that I can use to convince them?

Submission + - Interview: Why Hubble broke and how it was fixed (

angry tapir writes: "I recently had the opportunity to sit down Charles (Charlie) Pellerin, who was NASA's director of astrophysics when the Hubble Space Telescope launched with its seemingly fatally flawed optical system. Pellerin went on to head up the servicing mission that finally fixed the telescope and for that was awarded NASA's highest honour, a Distinguished Service Medal. Since Hubble he has done a lot of thinking about the problems that led up to the error and how organisations can best avoid making similar mistakes."

Are SSDs Really More Power Efficient? 222

Bakasama writes "Tom's Hardware compared the power performance of several available SSD cards with a Rotating HDD that was chosen specifically for its poor power efficiency. The results seem to fly in the face of current wisdom. 'Flash-based solid state drives (SSDs) are considered to be the future of performance hard drives, and everyone seems to be jumping on the bandwagon. We are no exception, as we have been publishing many articles on flash-based SSDs during the last few months, emphasizing the performance gains and the potential power savings brought by flash memory. And there is nothing wrong with this, since SLC flash SSDs easily outperform conventional hard drives today (SLC = single level cell). However, we have discovered that the power savings aren't there: in fact, battery runtimes actually decrease if you use a flash SSD.'"

Justice Dept To Investigate Google-Yahoo Deal 105

Anonymous Oddity writes "The Washington Post is reporting that the Justice Department's investigating the Yahoo-Google advertising deal. Obviously the deal controls a massive portion of the internet advertising market. US Antitrust law isn't entirely intuitive, but it does tend to frown on large deals between companies that operate on the same level if those deals can be interpreted as restrictive of trade."

Emoticons in the Workplace 258

Platonic writes "According to the New York Times, the Emoticon has become much more than something the kids do after school. The little guys seem to have found their way into the workforce: being used by stock brokers and even the U.S. Military. From TFA: 'I mean, it's ludicrous," said Ms. Feldman, 25. "I'm not going to feel better about losing hundreds of thousands of dollars because someone puts a frown face to regretfully inform me.'"

Submission + - SAS vs. SATA? 1

DJ_Double_D writes: "I was recently assigned to do some research on SAS and SATA hard drives and do a cost/benefit analysis to see what we should upgrade our servers to. I've been around SATA for a couple of years now and find the benefits of it very enjoyable as SATA hard drives are relatively fast, inexpensive, and storage capacity keeps on expanding. What about SAS though? I've never heard of it until I was assigned this project. Is SAS similar to SATA? Are we looking at 10k or above RPM's, similar storage capacities, data transfer speeds , and expandability to add more drives on in the future? For a small business would SAS even be possible?"

Submission + - Log on automatically in Windows Vista (

Artemis writes: "If you have a single-user PC and would rather have it automatically log on than display the Welcome Screen, this post is for you. Obviously do not do this on a computer that contains secure or confidential information. Also, don't follow the instructions for some older versions of Windows that involve editing the registry and adding your username & password to it. Those methods leave your username and password in unencrypted plaintext, and while having your computer automatically log on isn't the safest thing, there is no reason to store your password in plaintext when you can avoid it. Best of all, this way is much easier than editing the registry and stores your password as an encrypted LSA secret.

From the search/run box in the Start Menu, type netplwiz. Clear the check box for 'Users must enter a username and password to use this computer. The 'Automatically Log On' dialog box will appear, enter your username and password here and click 'OK'. This is the username and password Vista will use to automatically log on with every time it starts. Next time you start your PC it should load directly to the desktop!"


Submission + - Microsoft Is Still Growing

krelian writes: Microsoft rarely breaks out its specific product revenue, but that's what the chief financial officer did yesterday. In a rare moment of nuts-and-bolts disclosure, Chris Liddell laid out fiscal year-end revenue for seven products during Microsoft's annual Financial Analysts Meeting.

Microsoft-Watch complains that Windows and Office are not on the list but I guess it is pretty difficult to show a 20% growth rate on a product that already has 90% market share.
