Impressive web-development features in Safari 4
Today I stumbled across some impressive web development features in Safari 4 (or are they WebKit features?).
When you right click and select "Inspect Element" the Web Inspector window opens.

The Web Inspector provides numerous features which facilitate web development. Some features I found useful:
- Live HTML and CSS Editing: In the Elements tab, you can browse the entire page source and edit elements as well as CSS styles and preview them in the browser.
- Web Page Profiling: Personally, I found the resources tab most useful. In a single view I found out that there are some images on my front page which take a considerable time to load.
- Script Debugging: In the scripts tab, you can execute scripts in the page in debug mode.
Before discovering this, I used CSSEdit's web browser. CSSEdit's X-ray mode allows me to edit HTML and CSS and preview on live pages. Anyone aware of some other great web development tools for the mac?
Good PyObjc Tutorial
I've been looking for a good PyObjC Tutorial. The official Apple one is ages old and not comprehensive enough.
Fortunately the "An Epic Introduction to PyObjC and Cocoa" tutorial, is indeed an epic introduction to PyObjC and highly recommended for anyone planning to get started with Cocoa development in Python.
