Here is the latest Caml Weekly News, for the week of October 30 to November 06, 2007.

We are happy to announce the first public release of Marionnet, a virtual network laboratory. Marionnet allows users to simulate on a single host machine a complete network made of virtual computers, hubs, switches and routers connected by Ethernet cables; any single virtual device can be created, destroyed, modified, booted, shut down, paused or resumed at any time, while the rest of the network is running. It's also possible to simulate defects in network components, with a very fine level of control. The virtual network can also interoperate with the host machine network, using the 'plug' device. Virtual computers run unmodified GNU/Linux x86 application binaries on the Debian distribution we provide; graphical application relying on X are supported. Support for other non-debian x86 GNU/Linux distributions is easy to add. As the application is primarily targeted to students it features a very intuitive graphical user interface. The application logic is fully implemented in OCaml (see ), but Marionnet relies on User Mode Linux  and Virtual Distributed Network  for the low-level simulation part. We wish to thank Jeff Dike and Renzo Davoli for these fine pieces of software. The download page also contains a DVD image with Marionnet pre-configured on a 'live' GNU/Linux system, directly running from the DVD without need for installation. Marionnet is free software, released under the GNU General Public License. It comes with absolutely no warranty. Marionnet is written by Jean-Vincent Loddo (http://www-lipn.univ-paris13.fr/~loddo) and Luca Saiu (http://www-lipn.univ-paris13.fr/~saiu), and is sponsored by Université Paris 13 as an e-learning project.

We have two positions open with the F# team, probably based in Redmond though Cambridge UK may be an option. If you’re interested then check out these job postings :) Developer: http://blogs.msdn.com/dsyme/archive/2007/10/30/software-development-engineer-position-on-the-f-team.aspx Tester: http://blogs.msdn.com/dsyme/archive/2007/10/31/software-development-engineer-in-test-position-on-the-f-team.aspx OCaml skills are extremely welcome, along with the other skills mentioned in the above posts. Compatibility with core OCaml will remain an important goal as we move forward with F#, and we hope to expand our efforts in this regard.

Compiling prior releases, I advise using setenv MACOSX_DEPLOYMENT_TARGET 10.4. For top-of-tree, see http://caml.inria.fr/mantis/view.php?id=4439 I'd appreciate if someone could test the change on x64.

We are releasing our high-performance hardware-accelerated vector graphics software under a commercial source code license alongside the existing free edition: http://www.ffconsultancy.com/products/smoke_vector_graphics/?ol Until the license is put on the site, e-mail me if you'd like to read a copy. As an aside, several users asked us to provide bytecode versions for use with the latest OCaml 3.10 as well as 3.09 (still the latest in Debian testing). Our download statistics for last month show 94 hits for the 3.09 version and 56 hits for the 3.10 version, so many people seem to be pushing ahead with the latest technology!

CamlPDF is a library for reading, writing and manipulating PDF files and data. It is released under a BSD-style licence. http://www.coherentgraphics.co.uk/camlpdf.html New/updated Modules: Pdftext/Glyphlist/Fonttables: fonts and Unicode text extraction Pdfcrypt: Encryption and Decryption (40bit, 128bit and AES) Pdfimages: Preliminary support for image extraction Pdfwrite: Updated to support encryption and linearization Also, many bug fixes and new functions. PDF files it can't read are now very few and far between. There are small API differences, though most are limited to the addition of extra optional arguments. CamlPDF forms the basis of the cPDF Command Line Toolkit http://www.coherentpdf.com Thanks go to Haoyang Wang for a bug fix to string parsing in Pdfread.
Here is a quick trick to help you read this CWN if you are viewing it using vim (version 6 or greater).
If you know of a better way, please let me know.
If you happen to miss a CWN, you can send me a message and I'll mail it to you, or go take a look at the archive or the RSS feed of the archives.
If you also wish to receive it every week by mail, you may subscribe online.
