Improving grid performance

The F#.NET Journal just published an article about WPF:
"Many enterprise software applications require the ability to visualize a grid quickly and easily. This article looks at the performance of using the built-in WPF Grid control for a modest 80x120 grid of numbers and describes the design and implementation of a bespoke FastGrid control that uses WPF's low-level rendering APIs to make startup 16x faster..."

Basic use of LLVM from F#

The F#.NET Journal just published an article about metaprogramming:
"The low-level virtual machine (LLVM) is a freely-available high quality code generation library with support for many different architectures and platforms including x86, x64 and ARM. Programs are conveyed to LLVM in its intermediate representation (IR) which is an infinite register virtual machine. LLVM supports both static and JIT compilation of IR to native code. This article describes a compiler written in F# that can compile programs written in a small language to LLVM IR (using PInvoke) in order to evaluate them interactively..."

The F# Software Foundation (FSSF)

Several members of the F# community have combined forces to found The F# Software Foundation (FSSF) with the intention to "promote, protect, and advance the F# programming language, and to support and facilitate the growth of a diverse and international community of F# programmers". Note that Microsoft are still entirely responsible for F# on its native platform: .NET on Windows.

Although the FSSF was only just created, their website is already a gold mine of F#-related links. The "Getting F#" section refers to explanations of how to install F# on Mac, Linux, Windows, Android and iOS as well as HTML5 and GPGPU.

We fully support this movement to encourage wider adoption of F# and, in fact, we are currently experimenting with F# on the Raspberry Pi and intend to look at F# on the Google Nexus 7 tablet and the forthcoming Microsoft Surface Pro tablet.

SAT Solver

The F#.NET Journal just published an article about logic programming:
"Satisfiability solvers or SAT solvers are programs than solve logical problems. A boolean SAT solver is one than solves the problem of finding sets of variable bindings for which a given boolean expression evaluates to true..."
