Alternatives to gprof [closed]
...ot only that, we need to wake up from the myths. I appreciate that on some platforms it may be difficult to get stack samples, but if a problem is such that gprof will not find it, the fact that it is the only tool is small comfort.

I would assume, that some of the Linux code also works for the Unixes, except for the parts that read the /proc pseudo-filesystem. Perhaps on Unix these parts can be replaced by getrusage() and similar functions?

Why does Java switch on contiguous ints appear to run faster with added cases?
... In all fairness, the disassembly is specific to a given JVM on a specific platform. Others may translate it differently. Some might in fact use a hash table for a lookupswitch. It still won't perform as well as a tableswitch, but it could at least be close. It'd just take longer to JIT, and inv...

...fusing implementation details. I mean.. what is a school bus? It's a metal platform with a device in the front which consumes a refined petroleum product to drive in a cycle some metallic pistons, which in turn rotate a crank shaft attached to some gears which drive some wheels. The wheels have infl...
What's the difference between passing by reference vs. passing by value?
..."value" itself isn't very interesting (e.g. in C it's just an integer of a platform-specific size) -- what's interesting is what that value points to.
If what that reference type (that is, pointer) points to is mutable then an interesting effect is possible: you can modify the pointed-to value, and...
