&#62;sipp -sn uas
Error opening terminal: cygwin.


Funny thing is, the cygwin is installed on my sytems but it is actually NOT needed.
You will need cygwin if you want to compile the SIPP, otherwise it should work just fine without it.

		<description><![CDATA[While debugging a complex project have you ever experienced such a situation when the function is being called twice although it is only capable for getting called once by design?

For example, releasing some system resources, or smart pointer destruction.

In such cases it is easier to understand the problem when we can trace

    192.168.255.0/24

For those of us who do not frequently configure IP networks such notation may seem tricky and it has nothing to do with URI(s), ports and etc.
This is a &#8220;slash&#8221; notation which is formally called Classless Inter-Domain Routing (CIDR) notation.
It allows you to specify the [...]]]></description>

		<description><![CDATA[It was nice to find out in Jeremy Uejio&#8217;s Blog that 0xDEADBEEF is used on Linux (I assume it happens with debug versions) when you free memory.
According to this source, originally DEADBEEF was used in order to fill newly allocated memory.
On my Windows machine neither fresh nor deallocated memory is fancy.

		<description><![CDATA[This would be good as an interview question on C for those guys working with computations.

You have some code:


if (tmp != tmp)
{
 printf("it happened!");
}

You are running this application with tmp to be any of built-in types with no overloaded members (plain C).

Is there possibility that you would get  &#8220;it happened!&#8221; printed out
and what should [...]]]></description>
