Daniel Weinreb writes: GCL What's the current version number? 2.6.7, 2.6.8pre in Debian at the moment in 2.6.7 guise. I don't understand what you mean here. Cvs tag 'Version268pre' (aka 2.6.8pre) is the next stable release candidate. This is tested via uploading into Debian unstable as a 'package patch' against the released 2.6.7 sources.

So right now we have 2.6.7-36 in Debian unstable, which is the same as the current 2.6.8pre sources in cvs. When finalized, we will do a non-branch tag, and rename the sources to 2.6.8. Name of institution (company, etc) responsible for maintaining this implementation, if any. volunteers across the world Could you say something about how many developers are actively working on maintenance and development of this implementation? GCL development, like many open source projects, proceeds in bursts.

At such times, contributors number from 5 to 10. What platforms does it run under? By a platform, I mean a pair ofsuch as MacOS/PowerPC, Linux/Intel-64, etc. macosx, windows (mingw), solaris (sparc and intel), all 12 Debian Linux platforms What hardware architectures are supported for MacOS?

At the moment powrepc only. What does 'mingw' mean? 'Minimum GNU environment' or some such. Windows users seem to prefer this to cygwin as it is closer to native windows. Mingw provides a gcc port, etc.

I don't know what the 12 Debian Linux platforms are. I386 amd64 sparc s390 alpha ia64 hppa m68k arm(armel) ppc mips mipsel. macosx/intel still needs finalization What is the availability of the source code? LGPL,GPL (some modules) Is it distributed in an already-compiled form, or do you have to run 'make' and such?

Binary distribution in major distros. Can you say anything about fees for development and for runtime licenses, if any? none What's the history of this implementation?

For example, where was it originally written? Is it a fork of another implementation? What institutions were in charge of it at various points in its lifetime? Where did the CLOS implementation come from? GCL has a very long history. Origins in Kyoto Common Lisp, extensive modification by William Schelter at UT austin (AKCL), official adoption by the GNU project, most common base for many open source lisp projects (acl2, axiom, hol88, nqthm, one of the most common maxima platforms) CLOS comes from pcl.

Does it come with its own interactive development environment (IDE)? What IDE's are availabile? Basically no, but some emacs lisp ide files included in the distribution. Most users use emacs and an interactive shell windowwith tags completion, lisp shortcuts, etc. Please describe good things about this Common Lisp implementation that would make people want to use it rather than other implementations. Native object compilation, execution, runtime loading, and saving in portable restartable disk images. GMP fast bignums What does 'GMP' mean?

Re: Gcl-devel Volunteering For Macbook Pro

The GNU mp library is widely regarded as the fastest bignum implementation in the open source world. GCL has closely integrated its internals to make optimal use of this library. 1 instruction function calls via C pointers, resettable at runtime to a longer dubuggable path. Dynamic gc load balancing and optimization Faster generational GC runtime option based on read-only pages managed via segfault trapping and mprotect. tail recursion elimination unboxed numerical computation support very fast gprof profiling in cvs: I'm not sure what you mean here by 'in cvs'. Do you mean that everything below is in the latest cvs sources but not in release 2.6.7?

The 'head' or 'trunk' branch of cvs is versioned 2.7.0. This is released into Debian unstable as gclcvs. All major advancement progresses here until finalization, while leaving the 2.6 series a stable platform for the supported applications. two word cons immediate fixnums compressed function source stored in image and used in automatic inlining mutual recursion autodetection and state-machine conversion basically complete ansi support unboxed complex arithmetic Full runtime access to external C shared library functions not yet linked into the image, preserved across image saves, callable via one instruction C pointer indirection.

Re: Gcl-devel Volunteering For Machines

Fork-based parallelism, p-let, p-and and p-or. How does that work?

Without threads? Fork provides copy-on-write memory pages, which means the child process instantly inherits the parent's memory image, and only copies pages as they are modified (written) post fork.

GCL allocates on the C stack in the child to avoid GC calls there, which would write to many pages. The result is then printed in the child and read in the parent across a socket. Latency is around 2ms.

The huge advantage in avoiding threads, of course, lies in preserving a natural lisp syntax and keeping all the internals under the hood. The user need not explicitly worry about locks, mutexes, memory corruption, reentrancy/thread safety, spaghetti stacks, etc. Any lisp function which results in a printable result can be parallelized without modification in this way.

MPI support What does 'MPI' mean? Message passing interface, a standard library API used by (mpich, lam, openmpi.) to synchronize data structures across many nodes in a parallel computing cluster, aka 'beowulf'. This can also be used on a single machine to pass data via extremely fast SysV shared memory between processes. Some things I'm interested in: Is there support for locating the source code of functions and methods and so on, so that Emacs 'Meta.' Can work properly? Yes. Is there a profiling facility?

Yes, via gprof. Are there user-defined extensible streams? (Gray streams, simple streams?) No. Are there native threads, non-native threads, or no threads? (This may depend on the operating system or hardware.) Parallelism is fork and MPI based (no threads) I guess, same question as above.

This seems to be something different from anything I've seen in other Lisp implementations. This is a deliberate design choice, though not (currently) the most common.

About Raj's Work Raj Jayadev is a community organizer creating a model of grassroots collective action that gives individuals facing incarceration, their families, and their communities an active role in their defense. Jayadev’s work in criminal justice reform has grown out of his social activism work with (De-Bug), an organization he co-founded in 2001. De-Bug began as a magazine about issues affecting low-wage manufacturing, temporary workers, and it has since evolved into a multidimensional platform for community organizing, social justice advocacy, and multimedia storytelling by low-income, minority, incarcerated, and other disenfranchised communities. De-Bug’s most notable initiative is the (ACJP) and its “” model. Participatory defense adapts community organizing principles to criminal justice reform; it brings together a network of community members to help families navigate a complex criminal justice system and to enable chronically under-resourced public defenders to more effectively defend their clients.

Participants assist in the case discovery process, review allegations and evidence, and help construct humanizing personal biographies and videos of defendants. The practical support for attorneys and empowerment conferred on defendants and their families through participatory defense often prevents individuals from taking plea bargains out of ignorance or expediency. Former defendants and their family members often continue to volunteer with ACJP at the conclusion of their cases, using the knowledge they gained to assist and advocate for other families. Participatory defense is now spreading beyond California.

Hubs have been established in Pennsylvania, North Carolina, and Tennessee as part of the National Participatory Defense Network, and Jayadev is conducting training workshops in communities across the United States. Collectively, the hubs have saved nearly 4,000 years of potential prison terms for defendants through cases won or reduced sentences.

De-Bug is also expanding its advocacy efforts for systems-level change in the justice system, engaging in campaigns around bail reform, sentencing reform, and police accountability. By empowering ordinary people to take collective action in the defense of low-income individuals, Jayadev is addressing a critical issue in criminal justice reform—the imbalance of power between prosecutors and overworked public defenders. Biography Raj Jayadev received a B.A. (1998) from the University of California at Los Angeles.
