Writing your own STL Container
... This is interesting. How does your tester work? There are several parse errors, which are trivial (missing ';') but not sure how that verify destructor works. Oh, you meant assert(tester::livecount == 0);. Mmmmm, still not sure how this tester framework works. Could you give an example?

classical inheritance vs prototypal inheritance in javascript
...r.call(this, name, "male", dob);
if (this.age() < 18) throw new Error(name + " is a boy, not a man!");
};

var johnDoe = Man.new("John Doe", new Date(1970, 0, 1));

What's the fundamental difference between MFC and ATL?
...ge maps, COM was originally run-time bound using Macros, requiring lots of error handing and causing odd problems. ATL made it template based, compile time bound, and much, much easier to deal with.

INNER JOIN vs LEFT JOIN performance in SQL Server
...bles but possibly entire rows of information. And it happens so nicely, no error messages.
You can be very fast as getting 90% of the needed data and not discover the inner joins have silently removed information. Sometimes inner joins can be faster, but I don't believe anyone making that assumpt...
