I recently spent a bunch of time investigating why a Java application was spending a significant amount of time paused, even when garbage collection cycles were only taking ~200ms. The issue turned out to be other safepoints.
I did an upgrade install of 13.10, so I skipped writing a blog post about it. However, I did a fresh install of 14.04 on my macbook pro (rMBP). It seems quite stable so far, and is mostly the same as 13.10 and 13.04.
I’ve been using 13.04 (raring ringtail) daily build on my macbook pro (rMBP) for a couple days now, and things have been working great so far. Definitely a major improvement over 12.10, and for a daily build it’s been pretty stable too.
I’ve been working on an autonomous hexacopter, which has a Pandaboard ES running Ubuntu on it, and I wanted it to setup its own wifi network in the field for easy ssh access. Turns out this is pretty simple to do, but you need to configure several different daemons to get it working right.
Well, 12.10 (quantal quetzal) is out and runs a lot better on a Macbook Pro retina (rMBP) than 12.04. Just installed it on my retina and I think I can finally use it as my day to day laptop!
