The voter registration period for the Scheme Steering Comittee is over. I thought I could then post my statement of interest: I have been using Scheme for almost four years now. I use it mostly for studying programming languages and programming in general, prototyping and testing new ideas, but I have also developed and sold [...]

Compiling let
Following my previous Scheme toy interpreter in Lua, I have already tried twice to write a simple Scheme compiler. I failed mostly because the complexity grew too fast and I could not see any of it working before losing interest. But I then read Ghuloum’s paper on incremental compiler construction. It’s a very nice approach, [...]
Lua Programming Gems out!
Hot from the presses, the book is finally here. The table of contents, the front matter and the free chapter 2 are in the book homepage.
Equivalent of and-let*?
By this point I believe it’s clear that I am a big fan of Scheme. Lately I have seen a sharp rise of interest in Ruby in some virtual places I attend (#lisp-br, twitter, IM with coworkers etc.). I am sure Ruby is a fine language, even in spite of several complaints I hear from [...]
Lisp in Latinoware 2008
There will be presentations about Lisp in the V Latin America Conference on Free Software, via call-with-hopeless-continuation.
Meroon for Gambit-C
Meroon is a Scheme object system by Christian Queinnec. It is portable, fast, CLOS-like and reflexive. The Meroon home page cites versions for several popular Scheme systems, including Gambit-C. But the links to the Gambit-C version are broken. Doing a bit of research, that actually involved some guessing, I found the Meroon Gambit-C port in [...]
The need for speed
I have found a very interesting thread in the Gambit-C Scheme mailing list. Marc Feeley tries to dismiss the myth that floating-point calculations are inherently faster in C/C++ than in Scheme, which is taken as common wisdom. The the work of Bradley Lucier is cited as a case of very fast numerical Scheme code. Bradley [...]
Call me a whiner
But there are out there things like this: We don’t really care about the title but we want someone good (who doesn’t?). We need someone able to model and code well (No architect who never codes). The ability to communicate well with a team is also a big plus. You don’t need to speak French [...]
Misuse of technology, XML case
I do not have strong feelings about XML, be it for or against it. I don’t use it much because I use either S-Expressions with Scheme or Lua tables with Lua. I believe XML can be helpful, but people need to know how to use it. I have come across an application of XML to [...]
The 2008 Brazilian Symposium on Programming Languages
The XII Brazilian Symposium on Programming Languages is going to be happen in my home city of Fortaleza, on August 27th-29th. The programme looks very promising, with sessions about Software Transaction Memory in Haskell, concurrency with Lua (with the main architect of Lua, Roberto Ierusalimschy from PUC-Rio) and an invited talk of Shriram Krishnamurthi, the [...]
