When are you truly forced to use UUID as part of the design?
...ID generator/parser for Ruby, so I consider myself to be reasonably well-informed on the subject. There are four major UUID versions:
Version 4 UUIDs are essentially just 16 bytes of randomness pulled from a cryptographically secure random number generator, with some bit-twiddling to identify the U...

PHP_SELF vs PATH_INFO vs SCRIPT_NAME vs REQUEST_URI
...le 1.
PHP_SELF is different from SCRIPT_NAME only when requested url is in form:
http://example.com/test.php/foo/bar
[PHP_SELF] => /test.php/foo/bar
[SCRIPT_NAME] => /test.php
(this seems to be the only case when PATH_INFO contains sensible information [PATH_INFO] => /foo/bar)
Note: this...

handling zero-or-more and one-or-more style arguments

Why are unsigned int's not CLS compliant?
...st yes IronPython and IronRuby demonstrates that the CLR can provide a platform onto which you can build dynamically typed languages, the goal of the CLS was to provide a set of standards that transcend language functionality and allow them to interoperate sucessfully and safely. I don't think what ...
Performance of Arrays vs. Lists
...optimisation; arrays can be marginally faster if you use the indexer / for form - but IIRC believe it depends on the type of data in the array. But unless you need to micro-optimise, keep it simple and use List<T> etc.
Of course, this only applies if you are reading all of the data; a diction...

How to declare std::unique_ptr and what is the use of it?
...(thus violating the semantics of a unique pointer).
This is why the first form for creating a unique pointer is better, when possible. Notice, that in C++14 we will be able to do:
unique_ptr<int> p = make_unique<int>(42);
Which is both clearer and safer. Now concerning this doubt of ...
Secure Web Services: REST over HTTPS vs SOAP + WS-Security. Which is better? [closed]
...o use WS-Sec for both. They are doing this by putting the WS-Sec header information into the HTTP headers for the REST calls. Their security intermediary knows how to pull them out of either location to do the checks. First time I had seen this approach.
