Highly recommended article for anybody who tries to visualise data. The misuse of excel and powerpoint leads to too many 3D pie diagrams :-(. Any student should read his Tufte.

Ruport		05 Dec 05
		[print link all ]
Ruport is currently a combination of a neat proof of concept with some useful little scripts and utils that are quickly becoming rather powerful. The aim is to be a very handy report generation framework and library which will support an insane amount of input sources (CSVs,Excel,any Database Ruby-DBI supports,various ORMS, anything you can hack away at with parse/input,etc) and then output in an insane amount of formats (PDF,XHTML,XML,CSV,Excel,RSS,etc,etc) while leveraging a powerful set of tools that will munge, organize, and beautify whatever it is you need to report on. It’s not nearly there yet, but it’s on it’s way. Slightly more information available at the home page

Greasemonkey - making the browser more powerful

05 Dec 05

[print link all ]

Would you like to see price comparisons while browsing Amazon?

Would you like to use a website in ways its page authors have never thought of? Stop being the passive read,er be active. Amend the information.

Greasemonkey is a Firefox extension which lets you to add bits of DHTML ("user scripts") to any web page to change its behavior. In much the same way that user CSS lets you take control of a web page’s style, user scripts let you easily control any aspect of a web page’s design or interaction.

For example, you could:

Make sure that all URLs displayed in the browser are clickable links
Improve the usability of a site you frequent
Route around common and annoying website bugs
Use the Coral content network selectively.

Eric Hodel posted the announcement to the rails-ML.

Rubyforge

Action Profiler allows you to profile a single Rails action to determine what to optimize. You can use the Production Log Analyzer and action_grep to determine which actions you should profile and what arguments to use.

Information on the Production Log Analyzer can be found at:

rails-analyzer.rubyforge.org/pl_analyze

Action Profiler REQUIRES Ruby 1.8.3, even if you just use Ruby’s builtin profiler.

Action Profiler can use three profilers, Ruby’s builtin profiler class, Shugo Maeda’s Prof or Ryan Davis’ ZenProfile.

Shugo Maeda’s Prof: raa.ruby-lang.org/project/ruby-prof

Ryan Davis’ ZenProfile: rubyforge.org/frs/?group_id=712&release_id=2476

Gem Installation

 gem install action_profiler
