Tody I Learned: 1) There are a few password dictionaries out there for free download. You can find, for instance, the Rockyou-leaked passwords (among others) here: http://ift.tt/1cKEYyW. These are mostly (all?) illegally-acquired passwords that were put on the market, which the owner of the above link has cleaned of identifiable information and posted for free, for security testing purposes. You might want to try downloading the Rockyou password list and see if any of your passwords are in there. You might be surprised. Also, it's worth taking a look to get a sense of what kind of passwords people use. 2) A good rule of thumb to remember for Gillespie simulations (a kind of stochastic chemical reaction simulation based on molecular reactions) -- the more molecules you're simulating, the longer it will take. This is pretty obvious when you write it like that, but it really matters when the system you're simulating changes concentrations in the middle of a run..... 3) A species of Dictostelium (MY FAVORITE CLADE) called Dictostelium discoideum kills hostile bacteria by casting out a net of DNA covered with antibacterial agents when it detects a bacteria around.
