The only problem with that comparison is the first six example results have nothing to do with "Ruby on Rails".

This graph is biased by the fact that you're searching 3 words versus one. I personally qualify searches with "rails" throughout the day, but hardly ever actually search "ruby on rails". I imagine most other rails devs do as well, so this graph is missing a substantial amount of rails traffic.

As someone who is 6'8", 310lbs and spent 12 hours flying last week, I would have to strongly disagree. Until airlines provide a means of adjusting available room to compensate for height, its not appropriate to charge taller people more at all.

Alternatively, take advantage of your commute. I switched from driving to public transit and I've found the time can be incredibly productive, as its in between work time and at home family time, which makes it much easier to concentrate on what I need to do.

Hrmm... sat here thinking about the question, then thought 'a weather API would be nice, let me see if anyone else already answered that'.. ctrl-f weather.. oh great, the one guy who mentioned a weather API is also from Seattle.

I agree that the value add isn't significantly high for small cluster type of situations, and I would much rather just have a caching API available that charges on usage and allows you to specify an amount of redundancy.

However, the automatic failovers is very nice. From Vogel's blog: "Amazon ElastiCache automatically detects and replaces failed Cache Nodes to protect the cluster from those failure scenarios." That is definitely nice.

Elasticache does seem to be sitting in an awkward middle ground between renting of instances and paying for usage in an API.

Edit: after thinking about it more and reading some of the comments, I think an ideal setup would be an API to a memcached like datastore with buckets so I can specify max-size, redundancy, expiration methods, etc on a per bucket basis. Even nicer setup would be all of that plus redundancy and HA across availability zones and regions.

Nice trick using a proxied netcat command to forward ssh connections through a server. Was not aware of that, and I spend a lot of time running through a front ssh server, thanks!

A great way to dive into functional programming is to read the book that this topic discusses.
