I'm not overly familiar with the blame command, but I assume that you are looking for who changes a particular line of code. The easiest way is to use Perforce's 'time lapse view' available from both p4win and p4v.

Unicode in C++ |

What's the best practice of unicode processing in C++? |
Static typing is about contracts, not source code. The idea there is a need to have the static information on a single line of what "should" be a small method. Common guidelines recommend rarely exceeding 25 lines per method.
If a method is large enough that you can't keep track of a single variable within that me... |

I'm going to be implementing a PHP/mySQL setup to store credit card information.

If you're already programming in the .NET idiom, it's pretty easy to pick up on a lot of what's going on in the MVC Framework. Rails, on the other hand, can be pretty easy to pick up (granted, at a basic level) if you've never set eyes on Ruby before you start.

If you stick to pure managed code obfuscation, you can shave off quite a bit of an assembly size, and obfuscated classes/function names (collapsed to single letters) mean smaller memory footprint.

In an HttpHandler or HttpModule implementation, you cannot always access session from the BeginRequest event. There is another event you can handle, called OnAcquireRequestState. If you write your code in that event, then HttpContext.Current.Session will not be null. |

One potential engineering benefit is that in some cases obfuscation can create smaller executables or other artifacts -- e.g. obfuscating javascript results in smaller files (because all of the variables are named "a" and "b" instead of "descriptiveNameOne" and all the whitespace is stripped, etc). This results in fas... |
XSLT only handles the five basic entities by default: `lt`, `gt`, `apos`, `quot`, and `amp`. All others need to be defined as [@Aku](http://stackoverflow.com/questions/31870/using-a-html-entity-in-xslt-eg-nbsp#31873) mentions. |
If a big team of programmers really want to get at your source code and that had the time, money and effort, then they would be successful.
Obfuscation, therefore, should stop people who don't have the time, money or effort to get your source, passers by you might call them. |

Zigdon has the right idea except his regex isn't quite right. Use
