Thanks, Steve.  Yes, generally, you want "flow-through" ventilation in a PC.  If you have more than one fan, generally you either have them both blowing out (with an opening somewhere else in the case supplying cool air) or one blowing out and one blowing in.
The usual reasons for vibration, though, aren't from pressure effects but from simple mechanical things: Loose fasteners; crud on a fan blade, making it imbalanced; worn motor bearings; etc.  Any one of those items could have been ameliorated by your moving the fan--- you may have tightened a loose fastener; knocked some crud off a blade; re-oriented a fan so pooled lubricant flowed back into the bearings; etc.  Whatever the problem was, you found how easy it is to fix.  In fact, fans are so easy to move, tighten down, or replace--- they're often under $5--- there's really no reason to put up with excessive fan noise.  My simple rule of thumb: If you can hear a PC from across the room; or if it bothers you
*at all* when you're sitting next to it, it's too loud!

  Here's how to adjust that virtual memory.

 Four people use our home PC, running Windows XP.  Some of us like Internet Explorer, some like Firefox.  Is there a way to ensure we each get the one we like when we sign on?

So, we have a case of two foxes chasing four rabbits who decided to split hares.  Ha-ha-ha!
Windows allows you to set your own default Web browser.  So you don't have to use Internet Explorer.  In general, it's easy to change the default browser.
To change the default, click Start>>Control panel.  Double-click "Add or Remove Programs." Click the "Set Program Access and Defaults" button.  Under "Choose a configuration," select Custom.  Under "Choose a default Web browser," select your preferred browser.  Then click OK.
But on a shared computer, you'll have a problem.  Windows gives every user profile the same default browser.  That’s bad.  If you change your default browser, all other profiles are also changed.  That’s worse.
For unique profile defaults, I found a quick fix.  Fortunately, there is a program that can do the job.  It's called DefaultBrowser.  It also happens to be free.  I love that price.  DefaultBrowser's list of compatible browsers is small.  But it does include both Internet Explorer and Firefox.
To use DefaultBrowser, log in to your Windows account.  Double-click the DefaultBrowser icon.  Under "Default Browser Configuration," select the browser that you prefer.  Click Apply Changes.  Then click Exit.  Your selection won't affect the defaults on the other accounts.

Google has launched an instant-messaging program that allows text chat and computer-to-computer voice connections, a move that highlights the search giant's increasing competition with Yahoo, Microsoft and America Online.

Google's Web site late Tuesday provided a link to download Google Talk and stated that the software "enables you to call or send instant messages to your friends for free-–anytime, anywhere in the world." Google's messaging program is linked to the company's Web-based e-mail program, Gmail, and both are in a beta, or test, phase.

While Google Talk was expected, some industry observers questioned what innovation Google could add to lure loyal users and their millions of buddies away from established instant-messaging applications.

One advantage to Google Talk could be its ability to connect with users of competing services. The service is based on the Jabber open-source standard, which allows consumers to connect with other messaging systems that work with Jabber, such as Apple Computer's iChat, GAIM, Adium, Trillian Pro and Psi.

Google Talk currently works only on Windows, according to Google's Web site. Users need a microphone and a speaker to take advantage of the voice capabilities.

Take a peek at the interface graphics: 

Experts at SophosLabs™, Sophos's global network of virus, spyware and spam analysis centers, have welcomed news reports that authorities in Morocco and Turkey have arrested two men in connection with computer worm attacks that hit organizations such as CNN, ABC Television, The New York Times and the Financial Times last week.

According to media reports the FBI has confirmed that police arrested 18-year-old Farid Essebar a resident of Morocco born in Russia, and 21-year-old Atilla Ekici in Turkey on Thursday. The men are said to have gone by the handles "Diabl0" and "Coder", which are mentioned in the code of W32/Zotob-A.

The Zotob worms and related variants hit computers running Windows 2000 at a number of high profile companies by exploiting a security loophole in Microsoft's software.

"It appears that the computer crime authorities have moved very quickly in this case, and it will be interesting to see how the case progresses," said Graham Cluley, senior technology consultant for Sophos. "Because these men will be prosecuted in their countries of origin, rather than necessarily in the countries where businesses were hit, many will be interested to see how the investigations and cases brought against these men compare with incidents in other parts of the world."

Since the first Zotob worm emerged on 14 August, a series of variants and other malware have taken advantage of a critical security hole in Microsoft's software: the MS05-039 Plug and Play vulnerability.

"Astonishingly the time between virus outbreak and arrest is less than two weeks. The authorities were able to investigate quickly and co-ordinate internationally to affect arrests in Morocco and Turkey," continued Cluley. "Unfortunately, since the Microsoft security hole became public knowledge it has become a standard part of many virus writers' armory to include exploitation of the flaw into their malicious code. All companies need to defend themselves with security patches, up-to-date anti-virus software and firewalls for the highest level of protection." 

Phishing has been around for a while now, I would say everyone has a pretty good grip on how this scam works. If not, you should think about reading our phishing scam article form earlier in the year.

One thing that has been a constant in the phishing game is the attacks usually attempt to lure you in with a fake email that attempts to pose as a legitimate website in order to capture personal information.

Well we've discovered a new species of Phish—the Fax Phish—whose domain isn't the Internet, but rather your fax line.

The scam uses the guise of Pay Pal. No big surprise—next week it will be Ebay. It seems like these are the two online entities that attackers like to use.

Here's a run down of how this scam works: first you get a general email supposedly form Pay Pal with the following message"

Dear Paypal Customer,
Unauthorized person tried to reset the password from your paypal account. We would like to ensure that an unauthorized third party did not access your account. Because protecting the security of your account is our primary concern, you have to complete the affidavit form. Click here to download the form. Please send a fax in the next 24 hours to [number removed] with affidavit form completed.

Of course there was no account infiltration, your account with Pay Pal is fine, unless you fill out this affidavit and fax the information back.

In light of all the phishing attempts and identity theft lately, people may actually feel safer faxing information off to a seemingly reputable site in order to take care of an issue than sending it off in an email. The truth is, neither of these are secure practices, and you invite trouble by performing either. Email is not very secure and should not be used to send sensitive data, unless security services are put into affect. Faxing information out to a number based on an email is even worse. It's easier to fake being a company when you don't need to create even a bogus website to appear authentic.

As far as staying away from these threats, there's no guarantee, and remember to use common sense whenever your personal information is being asked for. For instance, if you do get an email and are genuinely concerned about an account or whatever they are using as bait do not reply by fax or email. If this happens to you, open your web browser and navigate to their website (do not link out of the email), this is the only way that you will know that you are at the site you are supposed to. If there is any legitimate issue with your account you should see it at the site or you can usually call customer service or at least send there customer support an email asking if something is wrong with your account.
Stay safe out there,

  Treatment for early stage kidney failure
 Appropriate treatment and management in the early stages of kidney failure, also known as chronic kidney failure, may slow or even stop the usual progress to complete failure (end-stage renal failure or ESRF or end-stage renal disease ESRD).
When your kidneys start to fail waste products and extra fluid will accumulate in your blood. A measurement of the amount of creatinine, one of these waste products, clearly indicates the extent of kidney failure.
By carefully managing your diet you can minimize the accumulation of waste products and extra fluids in your blood, and thus help your kidneys. By paying attention to what you drink you can do some of the work that healthy kidneys do in maintaining the right fluid balance in your body. A dietitian will advise you on changes you may need to make to your diet and fluid intake.
