Making Campfire Work for Me (and More Like IRC)
One of the companies I work with has decided to use the 37signals line of products for internal project management and communication (which I think is great BTW). This means that I sit in a Campfire chat room for the working hours of my day, along with a handful of other developers. I started to run into a problem, though, when I didn’t need to be talking with others. It is difficult to tell when people are trying to talk to me. Campfire has, by default, two methods of notifying you of new messages: an unread messages counter (dock icon or browser tab), and optional sound ‘dings’. When I’m trying to work on something though that doesn’t involve chatting with others, all the while the chat room still active with other developers, it’s really distracting to hear constant ‘dings’ or have to repeatedly check new messages to see if they pertain to me.
The situation for me is similar to lurking on IRC channels. But IRC has been around much longer than Campfire, and IRC client developers are familiar with the problem. Thus, many IRC clients allow you to specify keywords, that, when present in other users messages trigger some form of notification, like a sound or Growl message. Well, this clearly is the feature I needed to solve my Campfire problem.
Negative Word Matching with Regular Expressions
Today on the #codeigniter IRC channel someone asked about how to match a string that didn’t start with a specific word using a regex. I quickly threw out that, off the top of my head, /^(word){0}/ should work. Well, surprisingly, it didn’t. Turns out negatively matching words with regular expressions is a little more difficult.
After a little research I came up with a working solution: /^(?!word).*/

MySQL SELECT Entries Before NOW()
I’m in the business of making things faster. Using NOW() in a SQL query is something I’m going to complain about. Here’s a familiar scenario from the online publishing industry where future dating articles is a commonality:
You have a news site. You need to display only articles that have been published, and one of the criteria is that they need to have a publish_date before now. Easy, peasy, lemon squeezy.
SparkStats Widget Patch
Luc Betheder wrote a handy little widget for Sean McBride’s SparkStats plugin, which I recently started to use. I noticed, though, that whenever I made changes to my widgets the custom title I set for the Sparks plugin would get wiped out. So I fixed the problem in the plugin and thought I’d send the patch to Luc. Turns out, I can’t get in touch with him. You have to be registered on his blog to comment, but he has registrations turned off. Also, his email address was nowhere to be found. Hmm…slightly frustrating. I’m not giving up though, so here’s my patch (I’m also testing out the Google Syntax Highlighter):

FOWA & BarCamp Miami
Future of Web Apps (FOWA) Miami & BarCamp Miami are quickly approaching. I’m really looking forward to picking up tips on building better web apps, and meeting some smart people. I’m planning on giving a presentation at Barcamp, but I haven’t decided on what to talk about. I’m considering either “An Intro to Comet” or “Improving User Experience With JS Form Validation”, and I’m leaning more towards the former. Any suggestions?
I still have a lot to get done before the month’s end, including: launching the new and improved Statiksoft website, designing and printing affordable business cards, and, of course, writing my presentation. Add those things to the laundry list of other projects I’m trying to work on and it’s gonna be a busy month.
Also, BarCamp Orlando is slotted for early April, with two focused days! Kevin and I are gonna give a killer presentation on ExpressionEngine on the developer day. Be there.
