A couple of years ago I wrote about the Singularity project at Microsoft Research. Then I didn’t really hear anything more about it, and pretty much assumed it had run its (short) course like most research operating systems do. Today via OSNews I found a report about porting Linux’s ext2 filesystem to Singularity. The report is mildly interesting, but to me the most important piece of information is that Singularity is still alive and being used as a basis for ongoing research.
