coreyspitzer | 14 years ago | on: How github was hacked
Regarding the argument between whether this is a Rails framework concern or a Rails developer's concern, the fact that many tutorials and screencasts don't bring this vulnerability up has left the impression to a whole slew of developers that scaffolding and other step-by-step out-of-the-box ways to build things that Rails affords you are complete solutions that don't require any other modifications besides what's needed for your own business logic, etc. I think this is how we all missed something so simple. I think it's partly because of this convention/idiom groupthink.

I skimmed the article, but I didn't see at what arbitrary line Google considers "the fold"
coreyspitzer | 14 years ago | on: Why We Don't Work Overtime
Good post; What I think is important to point out (and what I've always told people) is that overtime is a result of failure: failure of planning, process, time/task/scope/resource management, estimation, etc.
coreyspitzer | 15 years ago | on: Why is 0.99999…=1?
The way I like to explain it to get it to quickly click in anyone's head (math geek and non-math geek alike) is so:
What is true about any two distinct numbers? Answer: there are an infinite number of numbers between them (e.g. between 4.00005 and 4.00006 there are 4.000051, 4.0000501, 4.00005001, etc. You can always add more zeros). But one cannot name a single number between 0.9999... and 1 because they are the same number.
Not really an actual, rigorous proof, but it serves its purpose.
