I get asked by people wanting to visit Iceland what they should do while they're there. Rather than re-type (and mostly forget) the whole thing I just give them a link to this.

Stuff that isn't this guide

...as if you didn't know how to use Google.

• I'm partial to The Lonely Planet guides whenever I visit other places. I haven't checked the one for Iceland but it's probably

Yesterday I upgraded our running elasticsearch cluster on a site which serves a few million search requests a day, with zero downtime. I've been asked to describe the process, hence this blogpost.

To make it more complicated, the cluster was running elasticsearch version 0.17.8 (released 6 Oct 2011) and I upgraded it to the latest 0.19.10. There have been 21 releases between those two versions, with a lot of functional changes, so I needed to be ready to roll back if necessary.

Our setup:

• elasticsearch

We run elasticsearch on two biggish boxes: 16 cores plus 32GB of RAM. All indices have 1 replica, so all data is stored on both boxes (about 45GB of data). The primary data for our main indices is also stored in our database. We have a few other indices whose data is stored only in elasticsearch, but are updated once daily only. Finally, we store our sessions in elasticsearch, but active sessions are cached in memcached.

Going to Japan 11th to 27th of May. Here's some ideas for things to do.

Before

• Get a rail pass for the bullet train network: http://www.japanrailpass.net/05/en05_3.html

  It would be ~550 EUR per person: http://www.japanrailpass.net/eng/en003.html

• Check if Icelandic or Spanish citizens need a visa. I don't htink so. Have sent an E-mail to the Japanese embassy to check.
