This means that Space Invaders can run in a seperate window from the main Factor GUI and you can even run multiple instances at a time. While the emulator is running you can still use the Factor GUI to browse, run code, etc.... more →

An image based programming language like Factor stores executable code in an image file. When Factor starts up it loads the image and starts executing the code stored in it. I wanted to explore some ideas with images and dynamic code generation so wrote a simple example on how to generate assembly, store it in an image and later load... more →
Slava has been working on porting Factor to the ARM CPU for running on a gumstix. Windows Mobile 5 devices also use a chipset that uses the ARM architecture. Doug Coleman, another Factor contributor, has a Windows Mobile 5 device and was keen to get Factor running on it. Between us we'd been trying out the various options to compile... more →

Instead of entering Factor code, hitting submit, and waiting for the result, you can type in a listener style REPL, hit enter and get the result back. It works much better.
