The core Caml system: status report and challenges, by Xavier Leroy

OASIS-DB: a CPAN for OCaml, by Sylvain Le Gall

OASIS-DB is a set of tools and a webserver that helps to manage OASIS enabled softwares and libraries to live together. It uses OASIS data to build a database and to understand the link between each packages. It also provides a backup site for tarball. The webserver is built on top of Ocsigen and Lwt.

This talk will show the architecture of OASIS and OASIS-DB and demonstrate some of its low paperwork publication scheme: upload your tarball to the website and let all others download, compile and install it using only 2 commands.

Sylvain Le Gall is an OCaml consultant working at OCamlCore SARL

Using OCaml to generate 198,278 lines of C, by Richard Jones

We use OCaml in the libguestfs project to generate large amounts of boilerplate C code. This short talk (10 mins) will explain what the problem that existing projects such as libvirt suffered from and how we successfully solved it, and what difficulties remain.

Developping Frama-C Plug-ins in OCaml, by Julien Signoles

This talk will show the Frama-C architecture and main services and how Ocaml is used to implement them. It also explains specificities of Frama-C plug-in development and their raisons d'être.

These addresses are from 2006, so they should have changed. It doesn't include breakfast.

Network/Laptop

TODO: This section dated from the first meeting and maybe need some update

During the conference, you can use your laptop and internet through Telecom ParisTech network. In order to do this, you will have two ways to connect:

  • ethernet cable
  • WIFI

The wifi configuration is quite tricky and will need to install some additional tools to connect using Linux.

Connecting through ethernet cable will be possible and will give you a better connectivity. Since the number of ethernet plug is limited people are invited to come with some ethernet switches to be able to offer more plugs.

Type E (French) Power plug will also be available, if your laptop doesn't have enough power to stay on battery a whole day. Just as for ethernet plug, people are invited to come with their national adapter for type E power plug and with power strip to be able to offer more plugs.

Participants

The list of participants is maintained here and you can register through this link. You need to have a valid login on the OCaml Forge to register.

There is enough room for 70 people in the room booked and the list of participants will be closed on 8th April.
