Here is the latest OCaml Weekly News, for the week of January 09 to 16, 2018.
Archive: https://discuss.ocaml.org/t/bioinformatics-with-ocaml-prohlatype/1415/1Jeff Hammerbacher announced:
If you're interested in an example of OCaml for bioinformatics, @leonidr just published a [preprint](https://www.biorxiv.org/content/early/2018/01/09/244962) about [Prohlatype](https://github.com/hammerlab/prohlatype). Check it out!
Archive: https://discuss.ocaml.org/t/ann-mariadb-1-0-1/1416/1Andre Nathan announced:
A new version of [OCaml-MariaDB](https://github.com/andrenth/ocaml-mariadb) is available on OPAM. This version fixes compilation on OCaml versions older than 4.06.0.
Archive: https://discuss.ocaml.org/t/dns-an-opinionated-dns-server-library/1418/1Hannes Mehnert announced:
I just pushed µDNS on GitHub https://github.com/roburio/udns, and wrote about it https://hannes.nqsb.io/Posts/DNS This is a DNS server library which includes authentication (TSIG), dynamic updates (NSUPDATE), and notifications (DNSNOTIFY). I use it since several weeks in production as MirageOS unikernel (both primary and secondary). It interoperates fine with ISC bind. By careful design, the authentication data (shared symmetric secret keys) is part of the DNS trie, and thus dynamically updatable -- furthermore, this allows for a nearly zero-configuration unikernel (the only required boot parameter is the root key to initiate updates!). See the examples in the repository (hidden under `mirage/examples`) for details. The main data structure is a Map, which key are resource record types, and its values are collections of resource records. My implementation uses GADT for tighter types! :)
Archive: https://discuss.ocaml.org/t/uri-1-9-6-available-with-improved-arm-support-and-build-times/1420/1Anil Madhavapeddy announced:
Uri 1.9.6 has just been released, which greatly improves life for those of you running on ARM-based systems. - Source: https://github.com/mirage/ocaml-uri/releases/tag/v1.9.6 - API docs: http://mirage.github.io/ocaml-uri/ There is an extra module included in Uri that bundles the contents of `/etc/services` into an OCaml module, so that you can perform service->port lookups from network servers. Previously, this resulted in an enormous OCaml pattern match for the full contents of `/etc/services`. This in turn uncovered [a bug in ARM code generation](https://caml.inria.fr/mantis/view.php?id=7608), which meant that anything involving Uris failed to work due to a dependency failure. @gasche put in a [different strategy for code generation](https://github.com/mirage/ocaml-uri/pull/114) which means that build times are faster for everyone. Enjoy! If anyone wishes to contribute to the Uri library, we are looking for a rewrite using [Angstrom](https://github.com/inhabitedtype/angstrom) to avoid the use of regular expressions for parsing. Get in touch if so...
Archive: https://discuss.ocaml.org/t/ann-new-release-of-vpt-a-vantage-point-tree-library/1428/1UnixJunkie announced:
vpt is the replacement of minivpt in opam. The code is there: https://github.com/UnixJunkie/vp-tree The new interface is: https://github.com/UnixJunkie/vp-tree/blob/master/vp_tree.mli There are more functionalities than before (all neighbors within distance d from query point, find, mem, root and remove) and it is no more a minimalist implementation. It also works for large number of points now if you construct a random vpt, unlike before.
Archive: https://discuss.ocaml.org/t/ocaml-2017-videos/842/13gasche announced:
Some of the videos have been uploaded three days ago, they are available on an [OCaml 2017 Youtube channel](https://www.youtube.com/playlist?list=PLnqUlCo055hU-o-XRz0hICTRWzcVR3JyX).Christophe then added:
The links were added to the [meeting page](http://ocaml.org/meetings/ocaml/2017/).
Here are links from many OCaml blogs aggregated at OCaml Planet, http://ocaml.org/community/planet/. 2017 at OCamlPro http://www.ocamlpro.com/2018/01/15/2017-at-ocamlpro-2/ my 2018 contains robur and starts with re-engineering DNS https://hannes.nqsb.io/Posts/DNS MacOS package updated https://coq.inria.fr/news/142.html
