comment Should I add 1 to my unknown string size when I create a char array to hold it via malloc?
Would also like to point out that whenever you know the length of a C string you should be using the "mem*" functions instead. Like memcpy(). The "str*" functions are a waste of time, looking for the zero terminator when you already know the length.

Ask yourself what will happen if you don't add room for that zero.

comment Should temporary files be saved to /tmp or the current working directory?
Definitely check the environment for the location of temporary files and never hard-code /tmp. Because a shared tmp has security issues, one mitigation I have often seen is to create per-user /tmp directories with no read-write permission for anyone else. It removes possible race conditions and symlink attacks.

comment Refactoring Switch Statements and is there any real use for Switch Statements at all?
@DavidArno: "the complete opposite"? The way I read it we said exactly the same thing. How can it be opposite?

comment Testing a windows game application against older versions of windows
@user2783034: You could use old desktops too but I think they use up too much space. Laptops can just sit in a small pile while not in use for testing.

comment Is storing data directly in a list node better than storing a pointer to data?
Some Gnome software changed to using GObject and GList, many years ago. The resulting 64-bit bloat from 10 MB RAM usage to 150 MB disgusted me. That was a 15X growth! For a RSS reader! Point is, try using a simple vector or array of the Content. No list. No pointers.

comment How to respond to a rude bug report?
@EricLippert: That bug report was handled very professionally. Although I agree with the reporter: doing anything with buffers in C without checking values first IS utter plebbery.

comment Why are there so few C compilers?
@supercat: Ah, a good weird one with overflows and integer promotion rules. It hinges on using 2 or 2u apparently.

comment Is throwing an exception an anti-pattern here?
I know that hardly anyone cares anymore but seriously. If you were implementing something like Redis would you really do a contains() call and then a get() call? Both calls need to hash or tree-search. The duplication is a pointless waste of time. If you possibly can, return the value and a "found" flag.

comment Why doesn't Java have optimization for tail-recursion at all?
Using recursion in C or Java always looks like stunt programming to me. No real reason for it, does not fit into the language, and serves only to confuse people.

comment Why are virtual machines required?
@TomJ: .NET also has an AOT compiler which it uses on installed library code. Not on applications, for some reason.

comment Is there ever a reason to use an array when lists are available?
@Mert: I believe (almost certain) that boundary checks are removed by the compilers when the usage is obviously correct such as in a loop with correct end checks.

+1 for long polling. Look up Comet en.wikipedia.org/wiki/Comet_%28programming%29

comment What did people do before templates in C++?
@IdeaHat: For generic functions look at qsort in the C library. It can sort anything because it takes a function pointer for the comparison function and passes a pair of void*'s.

A move must always leave the object in a destructible state.

comment Why is the complexity of fetching a value from an array be O(1)?
Your question seems to assume that you are searching the array for a particular value. But the question you actually asked is about fetching a value from an array from an already known array index.
