Tuples( or arrays ) as Dictionary keys in C#
...s are value types (structs), not reference types, so they avoid the memory allocation and garbage collection costs. Also, they offer conciser and more intuitive syntax, allowing for their fields to be named if you so wish. They also implement the IEquatable<T> interface needed for the dictiona...

Finalize vs Dispose
...uarantee that a finalizer will execute at all on any given instance.
Never allocate memory in finalizers or call virtual methods from finalizers.
Avoid synchronization and raising unhandled exceptions in the finalizers.
The execution order of finalizers is non-deterministic—in other words, you can...
How to compare 2 files fast using .NET?
...e .NET GC (because it's fundamentally optimized to keep small, short-lived allocations extremely cheap), and in fact could even be optimal when file sizes are expected to be less than 85K, because using a minimum of user code (as shown here) implies maximally delegating file performance issues to th...

...bal data? If it is the case, I'd restructure the program so that they are allocated dynamically. If the data is initialized, I'd read it from a configuration file.

C++ STL Vectors: Get iterator from index?
...s of a vector are stored contiguously, meaning that if v is a vector<T, Allocator> where T is some type other than bool, then it obeys the identity &v[n] == &v[0] + n for all 0 <= n < v.size()"

Stopping scripters from slamming your website
...robably not necessary.
for additional security, the code can be a one-time token generated specifically for the request/IP/agent, so that repeated requests generate different codes. Or you can pre-generate a bunch of random codes (a one-time pad) if on-demand generation is too taxing.
