...has very wide browser support. Things can get complicated when you need to include that information in requests to the server, as the # part of the URL isn't sent by the browser. There are ways round that, which includes the library I referenced. In addition, using the HTML5 history API helps make y...
Unit Testing bash scripts
...the following answer from a discussion group:
it's possible to import (include,
whatever) a procedure (function,
whatever it's named) from an external
file. That's the key to writing a
testing script: you break up your
script into independent procedures
that can then be imported into...
Java: Subpackage visibility?
...al design decision.
Either the method can be made public and all packages (including odp.proj and odp.proj.test) will be able to access the given methods, or the method could be made package private (the default visibility), and all the code that needs to directly access it must put in the same (sub...
urllib2.HTTPError: HTTP Error 403: Forbidden
...
It's true that some sites (including Wikipedia) block on common non-browser user agents strings, like the "Python-urllib/x.y" sent by Python's libraries. Even a plain "Mozilla" or "Opera" is usually enough to bypass that. This doesn't apply to the orig...

JPA or JDBC, how are they different?
...It is one of the underlying technologies behind most Java database access (including JPA providers).
One of the issues with traditional JDBC apps is that you can often have some crappy code where lots of mapping between data sets and objects occur, logic is mixed in with SQL, etc.
JPA is a standar...
Difference between std::result_of and decltype
...
result_of was introduced in Boost, and then included in TR1, and finally in C++0x. Therefore result_of has an advantage that is backward-compatible (with a suitable library).
decltype is an entirely new thing in C++0x, does not restrict only to return type of a functi...

Why is “while ( !feof (file) )” always wrong?
...(buffer);
The result we must use is nbytes, the number of bytes up to and including the newline (or EOF if the file did not end with a newline).
Note that the function explicitly returns -1 (and not EOF!) when an error occurs or it reaches EOF.
You may notice that we very rarely spell out the act...
