Running Ubuntu on a Macbook Air

Running Ubuntu on a Macbook Air

You don't have to be a slave to OS X! Here's a guide to a sane dual-booting setup with Ubuntu 12.10 on your shiny MacBook Air. This is written and tested for a MacBook Air 5,2 (Mid 2012), but likely works the same with any modern Macbook.

Install according to instructions at this URL:

TRIM Enabler for OS X Yosemite 10.10.3
#
# UPDATE for 10.10.4+: please consider this patch obsolete, as apple provides a tool called "trimforce" to enable trim support for 3rd party SSDs
# just run "sudo trimforce enable" to activate the trim support from now on!
#
# Original version by Grant Parnell is offline (http://digitaldj.net/2011/07/21/trim-enabler-for-lion/)
# Update July 2014: no longer offline, see https://digitaldj.net/blog/2011/11/17/trim-enabler-for-os-x-lion-mountain-lion-mavericks/
#
# Looks for "Apple" string in HD kext, changes it to a wildcard match for anything

logstash + you + me.

logstash needs full time love.

There are roughly 70 code contributors to the logstash project as of today. Many more exist as helpful folks on IRC and the mailling list. Others post awesome bug reports and feature requests. The community is simply awesome.

I've been working on logstash for about 2 years. All as a hobby - all part-time. About 70% of the current content (commits, 'git blame' lines, etc) are by me.

Unfortunately, I've never used logstash in production. (Embarrassing, I know!)

I'm embarrassed to answer user questions like "How do I optimize elasticsearch's storage?" with "Sorry, I've never used elasticsearch outside of my laptop."
