The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

“Great, just what I need … another D in programming.”

D is a systems programming language. Its focus is on combining the power and high performance of C and C++ with the programmer productivity of modern languages like Ruby and Python. Special attention is given to the needs of quality assurance, documentation, management, portability and reliability.

D is statically typed, and compiles direct to native code. It's multiparadigm: supporting imperative, object oriented, and template metaprogramming styles. It's a member of the C syntax family, and its look and feel is very close to C++'s. For a quick feature comparison, see this comparison of D with C, C++, C# and Java.

D Programming Language

D looks to be a very interesting language. Take the C/C++ syntax, remove header files entirely (A Good Thing™) and use a Javaesque “import” statement, salt with native string support (not the C/C++ halfbaked NUL terminated character arrays, nor the Java string class with special dispensation from the compiler), add in Pascal's nested functions, and LISP's anonymous functions, bake in garbage collection and contract programming, Haskel's lazy evaluation of parameters and you have D (with some other stuff I've left out).

All that, and it's written by a guy who's implemented a compiler or two and there currently exist two implemented compilers, the native one and a frontend for GCC makes this a rather serious attempt at a new language.

I'm impressed.

The only complaint I have of the language is the lack of concurrency support at the langauge level. Ten years ago it might not have been much of a loss, but today, the trend towards multiple CPUs makes this almost unexcusable.

Still, it's an impressive language.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
