WolframAlpha can take input in TeX form. Talk to Wolfram|Alpha in TeX
Smart design of a math parser?
A pretty good approach would involve two steps. The first step involves converting the expression from infix to postfix (e.g. via Dijkstra’s shunting yard) notation. Once that’s done, it’s pretty trivial to write a postfix evaluator.
Accurate calculation of CPU usage given in percentage in Linux?
According the htop source code, my assumptions looks like they are valid: (see static inline double LinuxProcessList_scanCPUTime(LinuxProcessList* this) function at LinuxProcessList.c) // Guest time is already accounted in usertime usertime = usertime – guest; # As you see here, it subtracts guest from user time nicetime = nicetime – guestnice; # and guest_nice from nice … Read more
How to calculate a Mod b in Casio fx-991ES calculator
This calculator does not have any modulo function. However there is quite simple way how to compute modulo using display mode ab/c (instead of traditional d/c). How to switch display mode to ab/c: Go to settings (Shift + Mode). Press arrow down (to view more settings). Select ab/c (number 1). Now do your calculation (in … Read more
