WordPress 2.7 ‘Cannot Modify Header Information’ Fix
I just recently upgraded a bunch of WordPress 2.5.1 blogs to 2.7 at work. Everything seemed to have gone perfectly until I got a call from someone who was trying to edit a draft she was working on. Everytime she clicked the ‘edit’ button, WordPress went to the post preview page and threw a couple of errors:
At the top of the page it said: ‘Post Preview (updated when post is saved)’
Then, towards the bottom, there were two more seemingly related errors:
"Warning: Cannot modify header information – headers already sent by (output started at /var/www/rchsupdates/wp-content/plugins/preview-frame.php:43) in /var/www/rchsupdates/wp-includes/functions.php on line 698"
"Warning: Cannot modify header information – headers already sent by (output started at /var/www/rchsupdates/wp-content/plugins/preview-frame.php:43) in /var/www/rchsupdates/wp-includes/functions.php on line 699"
Funny Pandora Fail
I started Pandora up at work today like I always do. The first song that came up was Hawthorn Heights “Blue Burns Orange”. No big deal. Then I looked at the album artwork…
I don’t think I’ve ever seen Hawthorn Heights before, but they’re kinda hot, in a weird “I think I’m too old for you” sort of way.
UPDATE
Just got another one. Puddle of Mudd with Alice Cooper’s coverart
First Ever ‘Donate To FOSS Day’
In case you don’t know what FOSS is, it stands for Free and Open Source Software. And even though you may not know it, chances are you are using it in some form everyday. I don’t think these guys get enough recognition for what they do, and now seems as good of time as any for a ‘change’.
My goal is to have one day out of the year (February 24) where everyone donates something/supports their favorite Free or Open Source project. It doesn’t have to be monetary.
Can you go without your coffee and send $5 their way? That’s always great and sometimes the most convenient way to donate. But remember, a lot of these guys don’t even accept monetary donations (more so the pure Open Source guys). Luckily there are a ton of other ways to help out.

Force External Drives To Mount To the Same Point
I recently rebooted my computer and normally I have my 2 internal drives and 2 external drives all mounted manually through the fstab file. If you don’t know how to do this, I wrote about mounting NTFS drives a while back. If you need help, just leave me a comment below.
Anyway, what happened was one of my external drives mounted, but to the wrong point. It is suppose to mount as /dev/sdg1 and instead mounted as /dev/sdh1. This probably isn’t a big problem for most people, but I have playlists that reference audio and video files from the external drive. Since Ubuntu mounted it to a different location, the playlist thinks the files don’t exist. The fix is fairly simple, here’s how to do it.
- Open a terminal window and type ’sudo fdisk -l’ to find the location of the drive

Simple HTML Validator Addon For Firefox
There are a ton of validation addons for Firefox and although I use several, I always have to have one particular one installed. It’s called Validaty. It’s nothing spectacular, it just does what it does. Validates (X)HTML.
After you’ve installed the addon here, you need to right click on an empty spot in the menu bar and right click and choose ‘Customize’. Then find Validaty and drag it wherever you want in your toolbar area.
Now whenever you want to check and see if a site validates, just click the button and it will validate against the W3C’s standards. If it validates, you get a green checkmark. If it doesn’t you get a red checkmark with the number of errors. You can then click on it and it will take you directly to the W3C’s website.
Enabling Gmail Offline Access
Gmail is the best online webmail by far IMHO. It’s biggest problem is that it needs to make some inroads into the business market so it can start making some money and start to push out Yahoo!Mail and Hotmail (or Live Mail or whatever Microsoft is calling it this week). Google has taken a big step towards being a viable alternative to things like Exchange or Zimbra by way of Offline Access.
Google is going to be doing a soft rollout of this labs feature so if you don’t have it yet, keep checking back. If you do have it, here’s how to enable it. I believe it will download up to 10,000 messages to your desktop, including attachments. You’ll be able to use Gmail almost exactly as you would if you were online including being able to search your mail like normal.
Find Out What Twitter Users Are Viewing Your Website
I’ve used the TwitterCounter badge that tells people how many followers I have on Twitter for quite a while now. It’s nice, but not really useful unless you’re a narcissist. They’ve recently released something much more useful: TwitterCounter Remote. Remote is a small piece of code that adds a widget to your site that tells you which Twitter users have visited your site recently.
All you have to do to set it up is fill in a few fields and have the service auto generate a small piece of JavaScript for you. Take that and paste it wherever you want it to show up on your site and you’re done.
I’ve already found and followed 10+ people who have visited my blog with this thing. I think it’s a brilliant way to increase your following on Twitter and to create better relationships with people you know are visiting your site (something basic Analytics can’t do).
Why I Love Ubuntu 8.10 After Four Months Of Use
I recently wrote a post about some issues I was having with Ubuntu 8.10 after I’ve been using it as my primary machine for the past four months. To balance things out, I wanted to write about why I absolutely love Ubuntu as well.
- It’s Free – I had to get this one out of the way. It still amazes my that an OS as powerful and stable as Ubuntu can be offered for free. Huge kudos to Canonical and the entire community that made this happen.
- Community – The Linux/Ubuntu communities are an amazing wealth of information and for the most part, incredibly helpful. The Ubuntu forums are crawling with seriously l33t hax0rs looking to help you out.
- Out Of the Box Software – An average user could probably use Ubuntu out of the box without the need to install anything else on it if they wanted to. There’s little that it can’t do after a fresh install.
