OpenGenera Install Party

Wed, 16 Jun 2010 07:48:16 GMT

As a follow up on June 1st's Lisp Machine Session, we will have an OpenGenera install party at this week's (June 17) Lisp Regulars' Table. Bring your laptop! Begin is as always 7pm @ c-base.

Lisp Machine Session Session

Thu, 13 May 2010 16:21:02 GMT

You are kindly invited to the next "Berlin Lispers Meetup", an informal gathering for anyone interested in Lisp, beer or coffee, organized by Hans H?bner and Willem Broekema. Continuing our series of meetings with presentations, the upcoming Berlin Lisp Meetup will be in New Thinking Store once more. We are happy to announce the theme:

Lisp machine session - When Lisp was _really_ cool

This month's Lisp meetup is about Lisp machines - Computers, that were made to run Lisp exclusively, with their makers so proud that the handbook started with the sentence "Welcome to Genera - The best software development environment available".

This will be a hands-on session. We'll have Symbolics MacIvory II to show, and we're going to play a little with the Linux based virtual Lisp machine. If you have a 64 bit Linux laptop, you can give it a spin, too.

Unfortunately, the New Thinking Store is not available this month, so we'll have the Lisp Machine workshop in Hans' office at 18:00 hours. Seating is limited, so if you're rather up for beers and chats, we'll meet at pizzeria "I Due Forni" at about 21:00 hours.

Here is the location info:

Hans' Office -- 18:00 to 21:00 Sch?nhauser Allee 177 10119 Berlin Tel. 030 4431 9642 "Sauna" signpost, across the alley, first floor, blue door, knock.

Pizzeria I Due Forni -- from 21:00 Sch?nhauser Allee 12 10119 Berlin

Both locations are very near station Senefelderplatz (U2), just across the street from each other.

Processing 1.0 is out!!!

Tue, 25 Nov 2008 19:00:13 GMT

CAMBRIDGE, Mass. and LOS ANGELES, Calif. - November 24, 2008 - The Processing project today announced the immediate availability of the Processing 1.0 product family, the highly anticipated release of industry-leading design and development software for virtually every creative workflow. Delivering radical breakthroughs in workflow efficiency - and packed with hundreds of innovative, time-saving features - the new Processing 1.0 product line advances the creative process across print, Web, interactive, film, video and mobile.

Whups! That's not the right one. Here we go:

Today, on November 24, 2008, we launch the 1.0 version of the Processing software. Processing is a programming language, development environment, and online community that since 2001 has promoted software literacy within the visual arts. Initially created to serve as a software sketchbook and to teach fundamentals of computer programming within a visual context, Processing quickly developed into a tool for creating finished professional work as well.

Processing is a free, open source alternative to proprietary software tools with expensive licenses, making it accessible to schools and individual students. Its open source status encourages the community participation and collaboration that is vital to Processing's growth. Contributors share programs, contribute code, answer questions in the discussion forum, and build libraries to extend the possibilities of the software. The Processing community has written over seventy libraries to facilitate computer vision, data visualization, music, networking, and electronics.

Students at hundreds of schools around the world use Processing for classes ranging from middle school math education to undergraduate programming courses to graduate fine arts studios.

+ At New York University's graduate ITP program, Processing is taught alongside its sister project Arduino and PHP as part of the foundation course for 100 incoming students each year.

+ At UCLA, undergraduates in the Design | Media Arts program use Processing to learn the concepts and skills needed to imagine the next generation of web sites and video games.

+ At Lincoln Public Schools in Nebraska and the Phoenix Country Day School in Arizona, middle school teachers are experimenting with Processing to supplement traditional algebra and geometry classes.

Tens of thousands of companies, artists, designers, architects, and researchers use Processing to create an incredibly diverse range of projects.

+ Design firms such as Motion Theory provide motion graphics created with Processing for the TV commercials of companies like Nike, Budweiser, and Hewlett-Packard.

+ Bands such as R.E.M., Radiohead, and Modest Mouse have featured animation created with Processing in their music videos.

+ Publications such as the journal Nature, the New York Times, Seed, and Communications of the ACM have commissioned information graphics created with Processing.

+ The artist group HeHe used Processing to produce their award-winning Nuage Vert installation, a large-scale public visualization of pollution levels in Helsinki.

+ The University of Washington's Applied Physics Lab used Processing to create a visualization of a coastal marine ecosystem as a part of the NSF RISE project.

+ The Armstrong Institute for Interactive Media Studies at Miami University uses Processing to build visualization tools and analyze text for digital humanities research.

The Processing software runs on the Mac, Windows, and GNU/Linux platforms. With the click of a button, it exports applets for the Web or standalone applications for Mac, Windows, and GNU/Linux. Graphics from Processing programs may also be exported as PDF, DXF, or TIFF files and many other file formats. Future Processing releases will focus on faster 3D graphics, better video playback and capture, and enhancing the development environment. Some experimental versions of Processing have been adapted to other languages such as JavaScript, ActionScript, Ruby, Python, and Scala; other adaptations bring Processing to platforms like the OpenMoko, iPhone, and OLPC XO-1.

Processing was founded by Ben Fry and Casey Reas in 2001 while both were John Maeda's students at the MIT Media Lab. Further development has taken place at the Interaction Design Institute Ivrea, Carnegie Mellon University, and the UCLA, where Reas is chair of the Department of Design | Media Arts. Miami University, Oblong Industries, and the Rockefeller Foundation have generously contributed funding to the project.

The Cooper-Hewitt National Design Museum (a Smithsonian Institution) included Processing in its National Design Triennial. Works created with Processing were featured prominently in the Design and the Elastic Mind show at the Museum of Modern Art. Numerous design magazines, including Print, Eye, and Creativity, have highlighted the software.

For their work on Processing, Fry and Reas received the 2008 Muriel Cooper Prize from the Design Management Institute. The Processing community was awarded the 2005 Prix Ars Electronica Golden Nica award and the 2005 Interactive Design Prize from the Tokyo Type Director's Club.

The Processing website (www.processing.org) includes tutorials, exhibitions, interviews, a complete reference, and hundreds of software examples. The Discourse forum hosts continuous community discussions and dialog with the developers.

had my last exam last week

Compiler Construction and Programming Languages

My prof asked what courses I had taken and I said mainly Lispy stuff and he wanted to know more and I kept on talking on how Lisp can be compiled efficiently despite its dynamic typing, him saying nothing and then asking about type classes and which languages had type classes.
I said: Haskell
Him: Who else?
Me: Common Lisp
Him: That doesn't count. Common Lisp has everything.
Me: You win. Java.

In the end, he gave me an A.

Currying

Thu, 10 Apr 2008 16:00:24 GMT

Currying in Common Lisp. Can't live without it.





(defun curry (function &rest args)

  (lambda (&rest more-args)

    (apply function (append args more-args))))

Comment by Marco Baringer

Posted on Sun, 15 Apr 2008

fwiw curry really likes a compiler-macro to go with it:


CL-USER> (defun curry (function &rest args)

                     (lambda (&rest more-args)

            
             (apply function (append args more-args))))

CURRY

CL-USER> (define-compiler-macro curry (&whole form function &rest args)

          
           (cond

            
             ((zerop (length args))

             
              function)

            
             ((< (length args)
call-arguments-limit)
              `(lambda (&rest more-args)

              
                 (apply ,function ,@args more-args)))

            
             (t form)))

CURRY

CL-USER> (funcall (curry #'+ 1) 1)

2

CL-USER> (compiler-macroexpand '(curry #'+ 1 2 3 4))

(LAMBDA (&REST MORE-ARGS) (APPLY #'+ 1 2 3 4 MORE-ARGS))
