Adobe Brackets

Adobe's Bespin-like editor, written in javascript / html.

Sweet. 

LightTable

Interesting this new surge of dynamic IDEs. First there was Brett Victor's awesome demo. Now there's LightTable (promoted on KickStarter, discussed on Quora)

Sporadic thoughts.

Is this implemented in the browser? (Bespin? CodeMirror)? Perhaps we're seeing this explosion of innovation as IDE authors move to the cloud.

A Kickstarter project? That's cool. But motivated by early investors getting licenses? Does it also mean that this next wave of software innovation will be abandoning Open Source as a model?

Elements of Jonathan Edwards's Subtext in the tree of updates. Of course, he's paying attention.

Bret Victor's Code / Drawing IDE

Excellent video

I'll have more to say and think about this.

HackerType

Possibly one of the more hilariously idiotic things I ever saw online. Impress your friends with fake coding skills. WTF?????

StackOverflow discussion on good in-browser code-editors. Worth following.

I'm expounding my usual "late-bound" tabs model of IDEs again, over on StackOverflow.

... late binding between the buffer in the editor and actual concrete thing you're working on, gives the editing environment more flexibility and power.

Think this is out of date? One place where the idea is back with a vengeance is in the browser, where you don't have 1-1 correspondence between tabs and web-pages. Instead, inside each tab you can navigate forwards and backwards between multiple pages. No-one would try to make an MDI type interface to the web, where each page had it's own inner window. It would be impossibly fiddly to use. It just wouldn't scale.

Personally, I think IDEs are getting way too complicated these days, and the static binding between documents and buffers is one reason for this. I expect at some point there'll be a breakthrough as they move to the browser-like tabbed-buffer model where :

a) you'll be able to hyperlink between multiple files within the same buffer/tab (and there'll be a back-button etc.)

b) the generic buffers will be able to hold any type of data : source-code, command-line, dynamically generated graphic output, project outline etc.

Take a look at AppJet. An educational take on the IDE in a browser.

Round-up of web-based IDEs.

Eclifox, plug Eclipse into Firefox.

Global System Builder (web-based IDE for IronPython)

This looks good. CodeMirror, an in-browser code-editor.

Smells like a move towards a hyperlinked, online IDE.
