Copying Files between S3 buckets. Juli 8, 2010 at 12:27 pm · Filed under AWS. Building on this article. Here is a simple ruby script, that copies files between two buckets of the same S3 account, omitting files already present (by name). This variant adds a list of path prefixes, so you can selectively copy only certain directories of your buckets. Furthermore it copies the original buckets ACLs for each key.

Connecting to redis via SSH tunneling. Dezember 2, 2011 at 12:46 pm · Filed under Allgemein. SSH tunneling is, of course, useful for a ton of services, but I happened to stumble upon it, when I wanted to connect to a remote redis server. If you have a redis server running on [remotehost], you can easily connect. To it (given you have ssh access to it, of course) via:. Ssh -L 9999:localhost:6379 [remoteuser]@[remotehost].

MoMolog » Ruby: map Array to Hash

http://momolog.info/2010/10/07/ruby-map-array-to-hash

Ruby: map Array to Hash. Oktober 7, 2010 at 8:49 am · Filed under Note to self. Sometimes you may wish to map an Array to a Hash in Ruby, like say, you got the output of I18n.available locales. Locales = [:en, :de, :fr]. And want to transform that into a Hash to fill a select element, like so:. En = 'EN', :de = 'DE', :fr = 'FR'}. How do you do that in the most concise way? First, there is always. Locales.inject({}) { hsh, sym hsh[sym] = sym.to s.upcase; hsh}. Hash[ [:a,:b],[:c,:d] ]. Hash[:a,:b,:c,:d].

MoMolog » Using throw and catch to tidy up our code

Using throw and catch to tidy up our code. März 29, 2012 at 12:17 pm · Filed under Rails. Let’s say we want a simple controller action that checks, if a given code is valid. It should return true and false and, if the code is invalid, give the reason (whether that is because it is unknown or because it has been used already). The action could look like this:. Now this deep nesting effectively hides the underlying algorithm, a simple one in this case. Straightens the code a bit:. We are down to one.
