Recently, the code hosting site GitHub deployed widely a tool called CodeQL with rather agressive settings. It does static analysis on the code and it attempts to flag problems. I use the phrase “static analysis” to refer to an analysis that does not run…

With the adoption of Ranges in C++20 (and with a lot of new additions in C++23), we have a lot of new, composable, range-based algorithms at our disposal. There are, however, several ways to spell the usage of such algorithms:

Programmers sometimes need to trim, or remove, characters, such as spaces from strings. It might be a surprising expensive task. In C, the following function is efficient: size_t trimspaces(const char *s, size_t len, char *out) { char * init_out{out}; for(size_t…

TAGE is one of the most accurate conditional branch predictors known today. However,
TAGE does not exploit its input information perfectly, as it is possible to obtain
significant prediction accuracy improvements by complementing TAGE with a statistical
