For the uninitiated, F# is a general-purpose programming language found in .NET. Contrary to C# who promotes objects as its first-class citizen (can receive and output objects in methods), F# promotes functions at its first citizens. This means that the preferred way of doing this will be through functional programming, but it doesn’t meet that … Continue reading Baby steps with F# and functional programming
When you’re designing a performance-sensitive computer system, it is important to have an intuition for the relative costs of different operations. How much does a network I/O cost, compared to a disk I/O, a load from DRAM, or an L2 cache hit? How much computation does it make sense to trade for a reduction in I/O? What is the relative cost of random vs. sequential I/O? For a given workload, what is the bottleneck resource?
When designing a system, you rarely have enough time to completely build two alternative designs to compare their performance. This makes two skills useful:
- Back-of-the-envelope analysis. This essentially means developing an intuition for the performance of different alternate designs, so that you can reject possible designs out-of-hand, or choose which alternatives to consider more carefully.
- Microbenchmarking. If you can identify the bottleneck operation for a given resource, then you can construct a micro-benchmark…

The .NET Compiler Platform, known by the name of Roslyn, was made available to the public as an extension to … Continue reading A better tomorrow for source code with Roslyn
Since Push requires stacks to manipulate its data, we need an implementation of this data structure. There is of course a .NET implementation, however, it is not a “functional” data structure, in a sense that it is mutable. It is easy enough to implement our own, purely functional, immutable stack.
F# list is a logical choice for an underlying implementation. It derives from Seq (i.e. implements all IEnumerable flavors), has a useful length property which we would like to have for our stack as well:
What remains is to implement basic operations, which are all static members of the Stack module.
These are pretty straightforward. pop function has a slight quirk: we would like to return both the value of the head of the stack as well as “the rest” of the stack. So the return type in this case is a tuple.
Another slight irregularity: stack functions work on…
