Movember - Donate to me please!

HI all (and long time no chat for many of you I am sure!), This Movember I've decided to donate my face to raising awareness about prostate cancer.  My donation and commitment is the growth of a moustache for the entire month of Movember, which I know will generate conversation, controversy and laughter. Prostate cancer is the most common cancer in men. One man dies every hour from the disease in the UK. This is a cause that I feel passionately about and I'm asking you to support my efforts by making a donation to The Prostate Cancer Charity. To help, you can either: -    Click this link http://uk.movember.com/donate/your-details/member_id/585776/ and donate online using your credit card or PayPal account . Or, -    Send cheques and CAF vouchers (made payable to 'The Prostate Cancer Charity Re Movember') directly to The Prostate Cancer Charity, First Floor, Cambridge House, Cambridge Grove, London W6 0LE. Be sure to include the person's name on the back of the

The #webperf prayer

"Steve Souders who art in Google, hallowed be thy name. Thy books did come, whose rules we run, on our sites as it was at Yahoo. Give us each request our cache-control headers, and forgive us our static cookies, as we compress those who request against us, And lead us not into CSS Expressions, but deliver us from Universal Selectors. For thine is the ySlow, the PageSpeed and the Smush.it (ok… Stoyan and Stubbornella) for ever and ever. Heck yeah!"

Filtering out spoofed emails in Outlook

I recently had a rash of email come in through my SBS 2008 (Exchange 2007) server purporting to be from eBay, Amazon etc. They were, of course, phishing emails but they were “close enough” to the real thing to get low SCL (Spam Confidence Level) and PCL (phishing confidence level) and hence were not rejected by the anti-spam features in Exchange 2007. They were however marked as “fail” or “softfail” by the SenderID checks (Sender Policy Framework aka SPF defines which hosts are allowed to send mail “on behalf of” a given email domain). Since the spammers weren’t on the allowed list, the email was failed the SenderID check. So, how do we ensure that emails that fail the SenderID check don’t get delivered to the user’s inbox? Well, the more dramatic solution is to just reject or delete any emails that fail the test. You can read how to do that here - http://technet.microsoft.com/en-us/library/bb125259.aspx   That was a bit drastic at this stage so I found another solution here

The "Grand National" Effect - dealing with traffic spikes

The Grand National is one of the largest events in the UK horse racing calendar, and that means hundreds of million of pounds at stake for the online bookmakers and gambling sites. It also means a major headache for the web operations teams as they deal with the inevitable traffic spikes hammering their sites, at a time when availability and performance direct equate to money won or lost. Site Confidence monitored the home pages of ten of the top ranking online gambling sites on the Grand National Saturday, and some fascinating patterns emerged in the lead up to the race (16:15 BST). Firstly, lets look at the Contenders…   You can immediately see a range of availability and performance, with some of the traditional “bricks and mortar” bookmakers considerably slower than the pureplay dotcom’s like “DotCom #1” and Bet365. Option 1 – Do nothing… and #fail The first option is to “do nothing and hope for the best” approach, as seen in the graph above for William Hill, a traditional “High St
