Simple fried mushroom spaghetti

A fast and easy dish, great for lunch, takes about 10-15 minutes, basically as long as it takes you to boil the water and cook the spaghetti, the rest of the prep can be done while the pasta is cooking.

Ingredients

• 100g fancy mushrooms. I buy these from Sainsburys (makes two servings)
• 4 or 5 regular button mushrooms
• 1 clove garlic
• Salt

ruby -e 'puts RbConfig::CONFIG["CFLAGS"]'

GDB output shows it reading symbold from Rub, but setting a breakpoint GDB can't find the symbol requested and ultimately never breaks:

# 1. Determine possible keywords by examining all dict words of the correct length and checking to see if when un-shifted they match the key
#  (note: it turns out there is only *one* word in /usr/share/dict/words) that matches the key when it is shifted
# 2. Decrypt the ciper text with all candidate keys
# 3. Count how many dict words appear in each candidate decrypt and sort by the count, display them in order
