[racket-users] CFP: PLOS '19: 10th Workshop on Programming Languages and Operating Systems
Do you use Racket in the implementation of operating systems or "OS-like" systems? Consider submitting a short paper about your work to the PLOS '19 workshop! Papers are due on August 9, a little over a month from now. Eric. --- CALL FOR PAPERS Tenth Workshop on Programming Languages and Operating Systems (PLOS 2019) October 27, 2019 Huntsville, Ontario, Canada http://plos-workshop.org/2019/ Sponsored by ACM SIGOPS In conjunction with SOSP 2019 http://www.sigops.org/sosp/sosp19/ Paper submission deadline: August 9, 2019 Notification of acceptance: September 6, 2019 Final papers due: October 1, 2019 Workshop: October 27, 2019 Historically, operating system development and programming language development went hand-in-hand. Challenges in one area were often approached using ideas or techniques developed in the other, and advances in one area enabled new capabilities in the other. Today, although the systems community at large retains an iron grip on C, modern programming language ideas continue to spark innovations in OS design and construction. Conversely, the systems field continues to provide a wealth of challenging problems and practical results that should lead to advances in programming languages, software designs, and idioms. This workshop will bring together researchers and developers from the programming language and operating system domains to discuss recent work at the intersection of these fields. It will be a platform for discussing new visions, challenges, experiences, problems, and solutions arising from the application of advanced programming and software engineering concepts to operating systems construction, and vice versa. Suggested paper topics include, but are not restricted to: * critical evaluations of new programming language ideas in support of OS construction * domain-specific languages for operating systems * type-safe languages for operating systems * the design of language-specific unikernels * language-based approaches to crosscutting system concerns, such as security and run-time performance * language support for system verification, testing, and debugging * synthesis of OS code * static/dynamic configuration of operating systems * static/dynamic specialization within operating systems * the use of OS abstractions and techniques in language runtimes * experience reports on applying new language techniques in commercial OS settings AGENDA The workshop will be a highly interactive event with an agenda designed to promote focused and lively discussions. Part of the workshop program will be based on paper presentations. PLOS welcomes research, experience, and position papers; papers describing industrial experience are particularly encouraged. The set of accepted papers will be made available to registered attendees in advance of the workshop. Participants should come to the workshop prepared with questions and comments. SUBMISSION GUIDELINES All papers must be written in English and should be formatted in the two-column ACM article style (<http://www.sigplan.org/Resources/Author/>, using the options sigplan,10pt). The CCS Concepts, Keywords, and ACM Reference Format sections are not required in submissions. Submissions are single blind: author names and affiliations should be included. Submissions must not be more than six (6) pages in length, using 10-point font. The bibliography does not count towards the page limit. The page limit will be strictly enforced, and shorter papers are encouraged. Papers must be submitted in PDF format via the workshop website. They will be reviewed by the workshop program committee and designated external reviewers. Papers will be evaluated based on technical quality, originality, relevance, and presentation. By default, accepted papers will be published electronically in the ACM Digital Library. The authors of accepted papers to be included in the ACM Digital Library will be required to sign ACM copyright release forms. The publication of a paper in the PLOS workshop proceedings is not intended to replace future conference publication.

[racket-users] Announce: Xsmith 1.0.0 Released
I am pleased to announce that Xsmith version 1.0.0 is now available. You can find it in the Racket package catalog at: https://pkgs.racket-lang.org/package/xsmith Xsmith is a library for creating fuzz testers, also known as "fuzzers," for programming language compilers and interpreters. In other words, Xsmith is a library for creating random program generators. Xsmith implements a domain-specific language (DSL) for defining random program generators. The DSL is used to specify a programming language's grammar, typing rules, and other information that guides generation choices. Xsmith also includes utilities for creating a command-line interface for generating a single program or starting a web server that generates one program per request. Xsmith is bundled with two example random program generators that were created using the library: one for C and one for Scheme. This is the first public release of Xsmith. It is neither feature-complete nor API-stable, but it should be usable by people other than the authors :-). We welcome feedback! Please send bug reports and fixes to . There is a mailing list, , for discussing Xsmith. Visit the list's management website to subscribe: http://www.flux.utah.edu/mailman/listinfo/xsmith-dev Happy fuzzing! Eric. -- --- Eric Eide .

The package hash might work; thank you for pointing it out! I'll have to
investigate how I can easily navigate from a package hash to a particular
version of the package. (I.e., the moral equivalent of `git checkout `.)

[racket-users] Git-Backed Racket Packages, git export
As described here <https://docs.racket-lang.org/pkg/git-workflow.html>, > When a Git repository is specified as a package source, then a copy of the > repository content is installed as the package implementation. That > installation mode is designed for package consumers, who normally use a > package without modifying it. My understanding is that "the copy of the repository content" is produced simply, e.g., by checking out the repository at the appropriate commit and then discarding the `.git` directory. An alternative would be to produce the repository content by running `git archive`. This would allow certain transformations to be made on the content, e.g., inserting the commit hash into one of the exported files. One could do other minor tricks as well, like excluding "junk" files. See the ATTRIBUTES section of the man page at <https://git-scm.com/docs/git-archive>. Is there a reason why the Racket package system doesn't run `git archive` to produce the content for the "non-developer" version of a package? Thanks --- Eric. -- --- Eric Eide .

I imagine it wouldn't be too hard to get Racket running atop a rump kernel or OSv --- but I haven't tried. It could be interesting, though, perhaps as a step toward something even more interesting. Surely you are right that writing everything in Racket would be a big job! Eric. -- --- Eric Eide .

[racket-users] Racket-ese for Scheme `define-record-type' protocol?
Hi! I'm translating a R6RS Scheme program to Racket, and I have a question about the best "Racket-ese" translation for Scheme's `define-record-type'. Consider the following R6RS definition: - (define-record-type racr-specification (fields (mutable specification-phase) rules-table (mutable start-symbol)) (opaque #t)(sealed #t) (protocol (lambda (new) (lambda () (new 1 (make-eq-hashtable 50) racr-nil) - What is the Racket translation of the protocol specification? Reading the online Racket docs, I don't see how to specify a different (and fresh per instance) value for every field within Racket's `struct` form. (#:auto and #:auto-value are not what I want; I need different values, and fresh values, for every created instance.) I guess I could "cheat" by defining the "expected" constructor myself: - (define (make-racr-specification) (racr-specification 1 (make-eq-hashtable 50) racr-nil)) - But this seems common enough that it would be built into `struct` in some way? Or maybe `struct` isn't what I want at all? Thanks --- Eric. (a Racket newbie) -- --- Eric Eide .
