A rev="canonical" HTTP Header

April 11 2009

Related: Save the Internet with rev="canonical" Since my post yesterday, I have noticed a lot of chatter all over the place about #revcanonical. (Not because of my post, but just because this idea has a lot of momentum.) Ben Ramsey wrote a rebuttal ... read more

Save the Internet with rev="canonical"

April 10 2009

There's a new proposal ("URL shortening that doesn't hurt the Internet") floating around for using rev="canonical" to help put a stop to the URL-shortening madness. It sounds like a pretty good idea, and based on some discussions on IRC this morning, I... read more

CSS Naked Day

April 09 2009

You might be wondering what happened to my design. As with years past (2007, 2008), I'm participating in CSS Naked Day to show my support for web standards, and to show off the design of shiflett.org: The idea behind this event is to promote web stand... read more

Smashing PHP

March 24 2009

We're trying to do something special at OmniTI. We've got great web talent, from operations to design (and plenty of everything in between). For my part, I bridge the gaps as much as I can, so I try to keep my finger on the pulse of many different web ... read more

Migrating from FeedBurner to Google

February 20 2009

When I logged into FeedBurner today, I was presented with the following message: Your FeedBurner account "shiflett" and all of your feeds should move to Google. I've actually been seeing this message for a few weeks, but today I didn't have the o... read more

Twitter Don't Click Exploit

February 12 2009

I've been posting to Twitter more than my own blog lately, but I noticed a Twitter exploit today that I thought was worth sharing in more than 140 characters. You can try the exploit for yourself at the following URL: http://umoor.eu/blog/yes-we-can... read more

Putting the Bow on OmniTI

January 18 2009

2008 was a marathon year, and in the final sprint to the finish (which included barely pulling off another PHP Advent), some very exciting news for us at OmniTI managed to miss my blog. I'd like to share it with you now and provide my thoughts. Firs... read more

Seven Things

January 09 2009

I was going to let the Seven Things meme pass me by, but the generous prodding of Elizabeth Smith, Elizabeth Naramore, and Theo Schlossnagle has managed to convince me that some of my readers might like to know a little more about me. If you're one of ... read more

2008 Highlights

January 09 2009

2008 is gone, and following tradition, I'm posting my personal highlights from the previous year. It's hard to believe that this is the 6th time I've done this, but I like the tradition, and I enjoy being able to review highlights from previous years (... read more

PHP Advent 2008

December 02 2008

Is it December again already? I like good traditions, so with the help of Sean and many others, PHP Advent is back again, this time with its own domain. I would call it a web site, but that might be stretching the truth at the moment. Jon is going to… read more
