Update: @improvekit’s Zeppelin for @Jira is now available in the @Atlassian Marketplace, making it one of the first @SqueakSmalltalk apps deployed via @SqueakJS into production.
Screenshot showing the blue JIRA menu bar on top and a desktop with four overlapping windows below. They contain graphs and text. One of them is surrounded by a halo of colorful handles for direct manipulation, an extended version of the standard halo in Squeak’s Morphic UI. Another window has a turquoise flap tab, indicating it can be retracted to the side. The third window shows a list of preferences, and the fourth is a help window with a hierarchical navigation tree on three left and text to the right.

On this day in 2013, SqueakJS drew the first pixels on the screen. This is that day's screenshot of the VM debugger implemented in @livelyweb, with the screen on the right, and panels for context inspector, stack, and byte codes on the left:

On this day 7 years ago, 2013-11-22, @codefrau added the first version of a byte code interpreter. It executed 43 byte codes and 8 sends before crashing - 2 weeks after the initial commit. github.com/codefrau/SqueakJS…

The Lively Debugger now works again with the latest #SqueakJS - and for the first time it's an easy local install thanks to @Docker and @robertkrahn! See github.com/codefrau/SqueakJS…
A screenshot of the SqueakJS debugger in Lively. It shows panels for the current context fields, the call stack up to the current do-it, and the do-it's compiled bytecodes for "3+4". The first bytecode (pushConst 3) is highlighted. Below the panels are various debugger buttons for single stepping etc.
