The most simple way to save host configurations for easy ssh’ing from Terminal on mac:
Add host entries to ~/.ssh/config file
This file doesn’t exist by default so you can easily create the file and add your host shortcuts.
For example, if you’d like to be able to type
user$> ssh MyHost
instead of ssh mycomplicatedhostname.host.com
Create the config file and add the following line:
I’ve been playing around with the iPhone SDK, and decided on a “Jumble Solver” as my first as a good learning project. It’d include a whole bunch of objective C and general programming concepts – Recursion, delegation, Interface builder, inheritence, sqlite.
My general approach was to build a decision tree with the available characters in the jumble, and compare the leaf nodes with an english dictionary. Finding a sqlite database of words … or rather a list of words was really hard. I stumbled upon a word list in text format found at the national puzzle solvers website. To dump that into a database I used the following simple ruby script. You’ll notice I limited the words to less than 7 characters. The search algorithm is n! complexity so limiting the jumble to 7 characters proved optimal performance. :
word_list.each do |word|
if word.length <8
db.execute(“INSERT INTO words (word) VALUES (?)”, word.chomp)
