One of the most commonly overlooked and under-refined elements of a website is its pagination controls. In many cases, these are treated as an afterthought. I rarely come across a website that has decent pagination, and it always makes me wonder why so few manage to get it right. After all, I'd say that pagination is pretty easy to get right. Alas, that doesn't seem the case, so after encouragement from Chris Messina on Flickr I decided to write my Pagination 101, hopefully it'll give you some clues as to what makes good pagination.

Before going into analyzing good and bad pagination, I want to explain just what I consider to be pagination: Pagination is any kind of control system that lets the user browse through pages of search results, archives, or any other kind of continued content. Search results are the o

If you had problems to use the gem therubyracer on Ubuntu 12.04LTS after install 

$gem install therubyracer

You just need to delete v8 library before install therubyracer, so...

  }
  
  service { 'rsyslog':

A long, long time ago...
I can still remember
How his blog used to make me smile.
And I knew that if he had his chance
That he could make their code enhance
And, maybe, they’d be happy for a while.

But August made me shiver
