$35 for 6 meals for two people at McDonalds? What?

Where I live, one meal at McDonalds is about $12. So 6 * 2 * 12 = $144. Not that much of a difference.

Also, if you aimed for 2200 calories per person per day with that $170, then it isn't really fair comparing to a single McDonald's meal, is it? It sounds like buying whole foods is cheaper.

(In a pinch you do log 2 by taking the log and dividing by the log of 2)

In a pinch it's easier to reason that since 2^10 = 1024, 2^11 = 2048, and 1626 lies between those two numbers, log_2 1626 is a bit more than 10.

Memorizing powers of two is useful for lots of quick mental estimation!

You can find walkthroughs by googling a bit (I myself wrote walkthroughs for the last 4 levels), but I'd highly recommend doing it without cheating. The amount you learn from figuring it out yourself is exponentially more than what you learn from reading a walkthrough. Most important is how you learn to think, by carefully looking for vulnerabilities and examining what you have control over and how the program uses your input.

Spend enough time learning the instruction set and the concepts involved and the answers will become apparent.

Do you have any advice for breaking into the field? I'm nearing the completion of a CS master and want to get into security. I completed Microcorruption a half year ago and loved it. I'm also mostly through Cryptopals, but I don't know anything about what the field looks like in practice. What kind of job openings (or titles) should I be looking for?
