Basically I want to get the number of lines-of-code in the repository after each commit.
The only (really crappy) ways I have found is to use `git filter-branch` to run `wc -l *`, and a script that runs `git reset --hard` on each commit, then runs `wc -l`
To make it a bit clearer, when the tool is run, it would outpu... | [

I found was using the `.lines()` method on a diff, which seems like it should give the added lines (but does not: it returns 0 when you delete lines for example)

What is the minimum set of HTTP verbs that a server should allow for a web service to be classed as RESTful?
What if my hoster doesn't permit ***PUT*** and ***DELETE***?
Is this actually important, can I live happily ever after with just ***GET*** and ***POST*** ?

I don't understand where the extra bits are coming from in [this article](http://en.wikipedia.org/wiki/S-box) about s-boxes. Why doesn't the s-box take in the same number of bits for input as output?
It is the way s-boxes work. They can be m \* n ==> m bit input , n bit output.

Can you use windows hooks or other methods to do code injection with c#? I've seen lots of things about code injection but all of them are done in C/C++. I don't know either of those languages and have a really hard time translating. Does anyone have any ideas on how to do this?

The first step turns your reduce/reduce conflict into a shift/reduce conflict, but the parentheses resolve that.
You're going to have the same problem with 'a b c': is it `a(b(c))` or `(a(b))(c)`? You'll need to also break off `applied_expression` and required `(applied_expression)` in the grammar.
