Sneak Peek at my new Music app

I'm working on a new music app that runs on iOS 7. Here's a few sneak peek screenshots of the app. 

FacePic now in the App Store!

The premise of the app is combining pictures from the back and front cameras on your device to create a single image, which can be shared on multiple social networks.

The app has a very simple interface, and responds quite quickly. Look for it in the App Store here.

AirBoard 2.0 Update

I've completed the 2.0 version of AirBoard. Key features include a new UI, more logic for the second screen display, and support for creating brackets. It's available in the AppStore right now: FULL or FREE.

The bracket creator works by setting up matches, and only advancing the tournament once all the matches have been completed. As you go through each match, completing it, the second screen scrolls to the next unplayed match. Eliminated contestants are stored at the bottom of the tableview.

Here's some screenshots of the app in action:

AirBoard update coming soon

I've got an update for my scoreboard app AirBoard coming out soon. This new version supports better rankings, and the ability to turn a leader board into a single elimination bracket. I'm currently working on updating the assets, and once that's done I'll be submitting.

Hundreds - Next Riddle (59)

From my sources online, I determined that this riddle was a Vigenère cipher. Vigenère ciphers are similar to Caesar ciphers, except instead of the contacts 3 character shift, it has a shift that is based on a keyword. The keyword is repeated until it is the same length as the text to encode.  i.e. If LEMON was the keyword, you would repeat it like so

LEMONLEMONLEMONLEMON

for a message like

THISISASECRETMESSAGE

Then, you take the location of each letter in the alphabet and add them together to get the new letter (it's explained more complexly on wikipedia, but this is what it boils down to). This would produce the following secret message:

ELUGVDEESPCIFARDWMUR

Thus, to decode one of these, you simply need a keyword, and subtract the keyword's letters from the encoded message's. This is the ruby script I wrote to do this:

file = File.new("vigenere.txt", "r")

cypher = file.gets

file.close

$key = {}

keyword = ARGV[0]

$letterArray = ["A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"]

string = ""

count = 0

cypher.each_byte { |i|

   if(i.chr == " ")

      string = string + " "

   else

      keywordLetter = keyword.split('')[count%keyword.length]

      offset = $letterArray.index(keywordLetter)

      index = $letterArray.index(i.chr)

      string = string + $letterArray[(index-offset)%26]

      count+=1

   end

}

puts "\n"+string+"\n\n"

The script takes a single argument, which is the keyword, and tries to decode the message. With that taken care of, all that was left was to guess the keyword. Judging by the previous messages, the keyword had something to do with a harp or a chord or something. I tried pretty much everything I could think of, and then tried RADIUS after looking at the cipher's achievements page. The secret message:

Being part of a bad riddle that nobody cares about.

This riddle looked more like the third riddle, where letter substitution was necessary. With my handy script, I began substituting letters for short words until they made sense. Pretty soon the solution popped out: "What do persistence and a golden harp have in common". Looks like the riddles are related somehow...

The next riddle wasn't too difficult. I simply went through all the letters one by one and filtered them into columns. Turns out 4 columns is the magic number. Reading down the columns revealed the answer.
