Comment It certainly has its on niche (Score 1) 154

I tried playing it and found it really impressive. The implementation is still beta-ish, but good enough to give it a try.

The first thing I make it do for me, is to launch my VNC viewer on my mac laptop, connect to my local head-less windows 7 machine, and click the iTunes play button to play some music there. It just worked (amazingly), and I found it to be a pretty good use case for a tool like this. A task like that cannot be easily automated. At least, it has not be the case with a tool that you just start trying for 5 minutes.

I can imagine that, if the image pattern matching can be extended to do recognition, such as face recognition / text OCR, and passed the recognized info back, or it adds webcam as its input device (instead of keyboard / mouse IO) it'll be overwhelming.

Besides, it really is an inspiring way of coding.

GUI

MIT Offers Picture-Centric Programming To the Masses With Sikuli 154

coondoggie writes "Computer users with rudimentary skills will be able to program via screen shots rather than lines of code with a new graphical scripting language called Sikuli that was devised at the Massachusetts Institute of Technology. With a basic understanding of Python, people can write programs that incorporate screen shots of graphical user interface (GUI) elements to automate computer work. One example given by the authors of a paper about Sikuli is a script that notifies a person when his bus is rounding the corner so he can leave in time to catch it." Here's a video demo of the technology, and a paper explaining the concept (PDF).

Comment Pugs 6.2.10 has just been released. :-) (Score 4, Informative) 144

I am delighted to announce Pugs 6.2.10, released during a slashdotting on geoffb's "Optimizing for Fun" column:

The release tarball will be available from CPAN shortly:

http://pugscode.org/dist/Perl6-Pugs-6.2.10.tar.gz
SIZE = 2394516
SHA1 = 3d8669fdccc3616c99cdde68659759b8b5782859

With two months of development, this release features more tightly integrated JavaScript and Perl5 code generator backends, a library interface to the Pugs system via support for the Haskell Cabal frameworks, as well as many new tests.

After the release, the push toward 6.28.0 will begin in earnest, with the newly specified container model and object model integrated back to the main runtime, fleshing out support for the remaining OO features.

Again, thanks to all the lambdacamels for building this new ship with me. :)

Enjoy!

Changes for 6.2.10 (r7520) - Oct 10, 2005

Feature Changes

Shared components

  • Support for the Haskell Cabal framework, exposing Pugs as a library to other Haskell users, paving the way for use in IDEs, as well as future Inline::Pugs and Inline::GHC modules
  • Adopted the code convention of expanding literal tab chars to spaces
  • JavaScript backend can be invoked with pugs -B JS
  • Perl 5 backend can be invoked with pugs -B Perl5
  • Pugs will now compile version ranges in use/require statements
  • Significant backend enhancements; see below
  • $?PUGS_BACKEND can be used to tell which runtime is in use
  • exec emulated partially on Win32
JavaScript backend
  • Passes 91% of the main test suite including TODO failures
  • Integrated with MetaModel 1.0
  • Faster code generation, taking advantage of -CPerl5 output.
  • Switched to continuation passing style CPS to properly support return, ?CALLER_CONTINUATION, coroutines, and sleep
  • Improved support for binding and autodereferentiation
  • Initial support for multi subs
  • Initial support for symbolic dereferentiation
  • List construction no longer creates new containers
  • Miscellaneous performance improvements
  • Named-only arguments +$x and ++$x cant be passed positionally anymore
  • Parts of the Prelude can be written in Perl 5 now to improve performance
  • Perl 5-like regular expressions mostly working

  • Support for lvalue subroutines foo = ...
  • Support for slurpy hashes in subroutine signatures
  • Support for the Proxy class not yet user-visible
  • Support for the eqv operator
  • Using for with only one element to loop over works now
  • int works correctly on special values like Inf or NaN now
  • substr returns a r/w proxy: substr$str, $pos, $len = $replacement
Perl 5 backend
  • Passes 33% of the main test suite including TODO failures
  • Integrated with the Perl 5 edition of MetaModel 2.0
  • Compiles and runs Perl 6 version of Test.pm
  • Infinite lazy lists, Pairs, References, and intrinsic classes
  • Multi Sub, Class, Match, exceptions, types and subtypes
  • Scalar, Hash and Array containers, with tieing, binding and read-onlyness
  • Support for an extensive list of operators
  • Supports eval with Perl 5 and Perl 6 code

Comment Nice number, but... (Score 2, Interesting) 167

It shoud also be noticed that they are simply using open source software instead of making contribution. It is the contribution that counts. Also, I think the are way more then 56.2% of developers who are using proprietary software in development process. There are some overlap between open source users and proprietary software users. But it is still a good number to tell people the impact of open source software in general.
