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 How can you build an effective team in a hot desk workplace
@Bohemian: If you require those things then yes you are stuck and lost and cannot be helped. So don't require them. Use a web page instead of "build lights."

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.

comment Why is polling accepted in web programming?
+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.

comment Move semantics in C++ - Move-return of local variables
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.

comment What is the responsibility or benefit of a Tokenizer?
Note that there are languages like Perl and C++ where the possible tokens are modified by where you are in the parsing. template<typename X<typename Y>> for example, changes the meaning of '>>' from '>>' to '>' '>'.

comment How can I hide my signature in a program?
Git allows the commit to set any timestamps that it wants. So I doubt you can rely on a git repo for any sort of evidence.

comment Why do C arrays not keep track of their length?
You have an statement in your question that isn't true. The heap manager does NOT have to track the length of each allocation. A slab allocator only has to know what slab the allocation is in. A 48 byte allocation goes in a 64 byte slab, but it could be 33 bytes or 51 bytes, the manager doesn't care.

comment How can you decompose a constructor?
I'd have to question if you ever intend to construct Enemy objects in code using literals. If you don't, and I don't see why you would, then build constructors that pull the data from a database interface, or a serialization string, or ...

comment Why should passwords be encrypted if they are being stored in a secure database?
You also want to hash the answers to their password recovery questions. Otherwise those can be used to get into other sites also, just like passwords.

comment Confusion about inheritance
@SamuelAdam: This sounds like a problem with your data store. If SQL use a transaction to safely delete and reinsert the object. Or depending on how it works force it to load ID 1 into a Member object instead of the default Customer. And your in memory objects should allow making a copy. So copy construct a Member from a Customer then write that back to the data store.

comment Utilizing a Java Concurrent Utility from a Web App
As an old hardened C/C++ programmer I have to wonder at Java people who import code which has function names longer than the math required to do it inline. ms/1000/60 isn't it?
