[Looking for Charlie's main web site?]

Need to solve browser problems? Did you know most modern browsers now have built-in developer tools?

When you're trying to understand why something's not working in your browser (page not rendering as expected, feature not working as expected, page content failing to load), it's useful to use of many any available tools which can show you what's going on, whether with respect to the HTML, CSS, or Javascript that may be running, or perhaps the communications between the browser and server.

For years, experienced developers have recommended client-side proxy tools like Firebug, Fiddler, Charles, and such. I list these and many others as a category in my CF411 site listing over 1800 tools and resources for CFers, in the category, HTTP Debugging Proxies/Sniffers/Web Client Test Tool.

I recently updated the list, though, to point out these "built-in" forms of these tools, now available in most browsers. If you may be in a place where you are "not allowed" to install new software (or are simply disinclined), knowing that the browser may have such a valuable tool built-in can be a real discovery, thus this entry.

Here's the content that I've added to that section:

  • In Chrome, see the Dev Tools, available under the "Customize and control Google Chrome" icon at the top right (the monkey wrench), then Tools>Developer Tools.
  • In Firefox 6 and above, see the "Web Console" feature in the "Web Developer" tools, available under the Tools menu.
  • In Internet Explorer, see the Developer Toolbar which is an ad-on for IE 6 and 7, and the f12 Developer Tools that are built into IE 8 and 9 (in the Tools menu).
  • In Opera, see the Developer Tools in Opera DragonFly, available in the Edit>Developer Tools menu in Windows, and Tools>Advanced on Mac.
  • In Safari, see the "Web Inspector" feature of the Develop menu.
  • I welcome additions/corrections/feedback.

The links I've given for each of these often have friendly introductions to using such tools. I can also commend an old but classic discussion of such tools, here.

Have you used these sort of tools? How have they helped you. Are you surprised to learn that the browsers now have such tools built-in? Chime in and share your thoughts. I may do a later blog entry or talk introducing using these tools for some common problems working with CF.

Charlie Arehart's Ultimate List of 200+ New ColdFusion 10 Features

Wondering what all is new in CF10? Have I got a list for you! :-) (revision 1.9, 217 items1

I've not yet seen anyone try to create an ultimate list of *all* the new features in CF10, so here's my shot at it. (This is based on the public beta. I will update it soon with info from the final release.) Of course many (including Adobe) have created lists that show perhaps a couple dozen of what they think may be the most prominent features, or the most interesting for them, etc. I've just not yet seen anyone list even simply all the features mentioned in the beta new features guide. That's what I'm doing here.

But to be clear, I am not listing every new tag and function (that would be tedious.) Instead, I'm listing them as concepts, and where warranted, any relevant subtopics that expand on the new feature.

I've got more to say about the list (how I created it basically from the 244-page CF10 new feature docs, and what you can do to help expand it). But some will want me to cut to the chase, so here's the list. Please check out the additional discussion after it.
