This article discusses hardware performance counter measurements obtained for a character search benchmark running on Intel x86 and SPARC hardware. Those results help to explain the big runtime differences between a SPARC T5 system and Intel x86 ones (SPARC being much slower), as well as differences between the different implementations ...
Assume you need to parse a record based format with flexible
width and one-byte delimiters. When using C++, the
algorithm is the obvious choice for efficiently locating the
delimiters. The idiomatic C solution is to use
The purpose of the
LD_LIBRARY_PATH environment variable is to instruct the
linker to consider additional directories when searching for libraries. Its
valid use case is the test of alternative library versions installed in
non-standard locations. In contrast to that, globally setting the
LD_LIBRARY_PATH (e.g. in the profile of a ...

used for formatting a string and writing the result into a buffer.
But sometimes it is surprising in how many ways
