I seem to have just missed the anniversary, but it turns out that Tribblix has existed for slightly over a decade.
The initial blog post on Building Tribblix was published on October 24th, 2012. But the ISO image (milestone 0) was October 21st, and it looks like the packages were built on October 4th. So there's a bit of uncertainty about the actual date, and I had been playing around with some of the bits and pieces for a while before that.
There have been a lot of releases. We're now on Milestone 28, but there have been several update releases along the way, so I make it 42 distinct releases in total. That doesn't include the LX-enabled OmniTribblix variant (there have been 20 of those by the way).
The focus (given hardware availability) has been x86, naturally. But the SPARC version has seen occasional bursts of life. Now I have a decent build system, it's catching up. Will there be an ARM version? Who knows...
Over the years there have been some notable highlights. It took a few releases to become fully self-hosting; package management had to be rebuilt; LibreOffice was ported; Xfce and MATE added as fully functional desktop offerings (with a host of others); a whole family of zones, including reimplementing the traditional sparse root; made available on clouds like AWS and Digital Ocean; network install via iPXE; huge numbers of packages (it's never-ending churn); and maintaining Java by default.
And it's been (mostly) fun. Here's to the next 10 years!
