Create an Opera extension in 5 mins

Because of Pocket’s super terrible tag searching, I think it’s kinda important for me to have a new read-later service. Readability is another good read-later service, and it supports Kindle, which is very good for people who loves to read on Kindle. However, the bad news is Readability doesn’t have extension for Opera or Mac application, and I really don’t want to switch to Chrome just because I want to add a link, so I decided to create a very simple extension just for myself.

Am I running 32bit or 64bit on Mac OS?

Very simple command, but very useful sometimes.

$ uname -a
