I did a fresh install of 16.10 on my Macbook Pro Retina mid-2012 (rMBP 10,1). It seems quite stable so far, and brings a bunch of small improvements over 16.04. Improved from 16.04 Startup Disk Creator can be used for creating the ISO Installer works more smoothly Nvidia drivers no longer required for good performance Intel power management works correctly Now for the directions! 1. Resize Partitions This step is pretty straight-forward.

I did a fresh install of 16.04 on my Macbook Pro (rMBP). It seems quite stable so far, and brings a number of improvements over 14.04. Improved from 14.04 No more special ISO (works with the default amd64 image) EFI is setup by default now Nvidia driver is automatically configured Now for the directions! 1. Resize Partitions This step is pretty straight-forward. Just open Disk Utility in OSX, and resize your existing OSX partition, so that there’s some free space for Ubuntu.

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. For those that don’t know, the VM uses safepoints to perform a variety of internal operations, and they involve pausing every Java thread. Garbage collection is the most well known, but many other operations such as deoptimization, and revoking biased locks require a safepoint as well.

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. Improved from 13.04 Better nvidia support (no more need to set kernel options) Now for the directions! 1. Preparation Just follow steps 1 through 3 in my first guide, to get rEFIt installed and prepare to install Ubuntu.

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. Improved from 12.10 Better modesetting support in the kernel (no more need for nomodeset option) Proprietary Nvidia drivers finally work right New wifi drivers, that actually work!
