Scheme: It's Not Just for Factorial Anymore

Scheme: It’s Not Just for Factorial Anymore.
It isn’t.

Org Mode Babel Support for SML

David recently pulled in a couple of changes to make OB-SML happy with Emacs’ package manager, SML-MODE 6.4, and Org Babel. For you reproducible research junkies, this is super-cool. It is already out on Marmalade.

Reproducible Research, Literate Programming and Inter-Language Programming with Babel

Babel is about letting many different languages work together. Programming languages live in blocks inside natural language Org-mode documents. A piece of data may pass from a table to a Python code block, then maybe move on to an R code block, and finally end up embedded as a value in the middle of a paragraph or possibly pass through a gnuplot code block and end up as a plot embedded in the document.

My current approach is to use multiple languages, build scripts, intermediate files to share data, and finally weave it together inside of LaTeX. The babel way looks intriguing, with excellent support (via Emacs modes) for numerous languages. Very exciting.

DIagrams Through Ascii Art

ditaa is a small command-line utility written in Java, that can convert diagrams drawn using ascii art (‘drawings’ that contain characters that resemble lines like | / – ), into proper bitmap graphics.

You have to see it to believe. For you text-heads out there, yet another great tool for us!

Unofficially: R7RS Small has been ratified

Unofficially: R7RS has been ratified.
Congratulations and thanks to all of the working group’s hard, hard work on completing what was by some measures an impossible task.
There will be one more draft to address a few concerns.

Husk: An R5RS-compatible Scheme written in Haskell

Husk is a dialect of Scheme written in Haskell that adheres to the R5RS standard. Advanced R5RS features are provided including continuations, hygienic macros, and a full numeric tower.

CB750F: Day 35: Totally Idle

Left unable to bench sync the butterfly valves, I finally pulled the bolt out only to find that it was in clearly bad shape. When the nut reaches a certain point, it just won’t go any further. On my carbs, the nut is threaded, and so too is the mounting point on the rod (that the butterfly valves attach to). Running the nut up and down the bolt (viced in) cleaned it up, but when it goes through the rod it gets “screwed up” again. Looking closely you can see the rough edge after going through the mount point on the rod.

Kind of a funny way to end the semester, but knowing that it will get repaired “right” makes me feel pretty happy. On the way out noticed a nice placard on the door, too.

ISLISP

The ISLISP programming language is a member of the Lisp family of programming languages. It attempts to bridge the gap between the various incompatible members of the Lisp family of languages (most notably Common Lisp, Eulisp, LeLisp, and Scheme) by focusing on standardizing those areas of widespread agreement. It is a small language, closer to the size of Scheme than to Common Lisp, for example.
The most recent change to the specification occurred in 2007.
The design of ISLISP had these design goals:

Compatible with existing Lisp dialects where feasible.

Provide basic functionality.

Object-oriented.

Designed with extensibility in mind.

Gives priority to industrial needs over academic needs.

Promotes efficient implementations and applications.

John Cowan mentioned it on scheme-reports, so I was curious.
