Is metaprogramming possible in C#?

Metaprogramming is possible in .NET (see compiler compilers, regular expressions, code DOM, reflection etc.) but C# is not capable of template metaprogramming because it does not have that language feature.

Benchmarking in the web age

The TechEmpower website contains some fascinating benchmarks of servers. The results on this benchmark of multiple requests to servers provide some insight into the performance characteristics of .NET on a modern problem. Specifically, the C# on ASP.NET Core solutions range from 2.5-80× slower than fastest solution which is written in Rust. In fact, C# is beaten by the following programming languages in order: Rust Java Kotlin Go C Perl Clojure PHP C++ Furthermore, .NET Core is Microsoft's new improved and faster version of .NET aimed specifically at these kinds of tasks. So why is it beaten by all those languages? I suspect that a large part of this is the change in workload from the kind of number crunching .NET was designed for to a modern string-heavy workload and I suspect .NET's GC isn't as optimised for this as the JVM is. As we have found, .NET has really poor support for JSON compared to other languages and frameworks, with support fragmented across many non-stand...

The rise and fall of OCaml

Image
After over 3 years, The OCaml Journal is finally closing down. New subscriptions offer access to the 75 existing articles and only a few more articles will be published, to honour outstanding subscriptions. This marks Flying Frog Consultancy Ltd. officially pulling out of the OCaml market as our remaining OCaml products (such as the OCaml for Scientists book) require no on-going maintenance. This change has, of course, come about due to a dramatic fall in our revenue from OCaml products since 2007. This is partly because we decided in 2007 to jump ship to Microsoft's new F# programming language . However, the same trend can be seen in the rate of posts to the OCaml mailing lists, which has fallen 60% since 2007 and has now reached its lowest level for a decade: We blame the inability of OCaml's garbage collector to allow threads to run in parallel as the primary reason for this mass exodus. OCaml was an awesome tool in the late 1990s and, by 2004, many people were finding t...

When celebrity programmers attack: Guido on tail calls

Guido van Rossum, the celebrity programmer responsible for the Python programming language, published a horribly misinformed blog post last week that was meant to explain why tail calls are "unpythonic" and do not deserve a place in the Python language. Given the simplicity of the subject matter and the widespread availability of accurate information from experts like Will Clinger , it seems remarkable that anyone would still be confused about tail calls. Although the presence or absence of tail calls in Python is unimportant, this is still serious because Python is the new BASIC and, consequently, Guido is abusing his celebrity status by misguiding a huge number of young programmers. Indeed, this is very visible on the ensuing Reddit discussions where the majority of comments are factually incorrect. Definitions A tail call is a call that appears as the last thing a function does before it returns. In functional languages, this means the caller is returning the result of ...
