From: HowtoConfigureLogging on the Rails Wiki site.

Getting monochrome log messages

Removing the colour escape sequences that are used by default is quite
simple. Simply set colorize_logging to false:

ActiveRecord::Base.colorize_logging = false

Note that the colorize_logging method doesn't appear in
ActionController (why?[because the only module in rails that adds
color to the logs is ActiveRecord -jean]).
CryoPID - Freeze/Hibernate a process to disk and restore it later.

Wow, this is so cool, you could have a process running, freeze it to disk with CryoPID, then reboot the computer, and unfreeze the process.

Unfortunately, it doesn't yet handle my use-case, where I have an Emacs started with "screen". It'll be cool when that happens.

Two very cool text editing tools for Firefox:

TextareaResize - is a Greasemonkey plugin that allows you to resize any text area by pressing Ctrl-Enter.

It's all Text is a Firefox plugin that gives you a little button "Edit" at the bottom of any text pane. When you click on it, you can edit your text in the editor of your choice. In my case, that would be Emacs, of course.

A circumzenithal arc.

DHTML Goodies is some pretty sweet javascript/DHTML libraries, with really neat things like tabbed panes. Here's the >Reference manual for DHTML Goodies
Living on the edge with Rails

Edge Rails is the latest bleeding edge Rails version, I usually use stable, but needed to use Edge for a recent project. It's pretty simple, just go:

rake rails:freeze:edge
rake rails:update

and to check what version your server is running:

ruby script/about

Association Options :order.

In a recent project I needed to add a method to a Ruby on Rails model that would pull out the latest entry in a related table.

has_one :order => 'key'

worked great!

I just got interviewed by Google! Trippy!

They ask REALLY hard questions.
Using Campfire for blog comments - Somewhere in this is a revolutionary idea, I'm not sure exactly where, but we're getting close to something very special. Imagine if your blog was more like a conversation with your users, and conversations could link not just to the inital post, but across other entries on your site, and to other sites. That combined with the idea of prescence, so that a reader can interact with other people reading the article at the same time. And now link that in with feeds. Somewhere in here is a new model of people interacting with people.

I had a great time at the recent PHP Vancouver conference, it was really well done. I'm a totally Ruby fan, but I learned lots about performance of web applications at this conference. Rasmus Lerdorf gave a fantastic talk, and I really need to be doing:

I'm an avid listener of podcasts, and use the excellent podcatching software. It runs from the commandline and is absolutely gorgeous. It uses an XML file for configuration, and to add files to it, I use Emacs and add a new:


to the end of the file. That's really sweet, and slightly hardcore.

To run it, I just have a crontab entry that runs at times when I'm usually not on the computer:

0 5,13,18 * * * /usr/sness/peapod/ >& /dev/null

So, when I wake up, come back from the gym, and after supper, there are podcasts all ready for me! So sweet.

I was reading the logfile for it recently, and was wondering what the following meant:

etag unchanged, not fetching:

So, etags are actually really cool, here's RFC 2616 which describes it in detail. And a blog post about it.

Basically, etags are returned by the server in the content header, and tell you if the content of the page has changed or not. If it hasn't, you can add the If-None-Match header to your request, so that you don't have to download the URL if it hasn't changed. Sweet.

How to build your own heart monitoring device, a simple ECG

Remember, use batteries, because only 500mA at 120V can kill.
I've been getting more and more into web typography recently, and I found these articles very interesting. Everyone has different ideas about how to design web interfaces, and these articles have similar taste, to have a simple, elegant, non-cluttered design, with text as the primary focus. Other people have different ideas. They are all interesting, but don't take them too seriously, there is no "right" way, just a lot of different ways. That said, these are some good ideas:

plotr - A very cool new prototype.js based line chart library. Looks intresting, it uses Chart.

I still like doing my graphs by hand in ImageMagick, but plotr looks like an interesting idea. Not sure if this is the kind of thing you want to be doing in Javascript, though, but if you could get them to be dynamic, that would be very useful.
Finally, some good documentation for Prototype.js.
Javascript event capture explained.
A good article about the history of AJAX with some good points about making good user interfaces for the web:

"Ask how long it takes to execute a requested task," he said. "If it takes more than 2 seconds, consider not providing the task or splitting it up into small, user-controlled tasks."

"A good tool should be transparent, should execute actions in less than half a second and should involve interactive bottom-up learning, "because you change your mind as you go," he said."

"Also, "You don't need to remember how an app works," Bosworth said. "There's a big difference between making something easy to use and making it productive." In other words, just because people can easily learn to use an application doesn't mean using the application will make them more productive."
An article about some neat logging modules for Apache. Some really handy ones in here. I use the Rails logfile and the Apache logfile in combination, and these modules could be quite useful.
