Sharing your code
If you need a place to host a project so that others can help with it, we suggest github, but if you are using darcs patch-tag is just dandy as well.
You can also apply for an account on the community server.
Projects
If you have a project that you want to work on at the Hackathon, please describe it here.
Since Hackathons are great for teamwork, consider joining one of the projects mentioned below. If you're interested in one of these projects, add your name to the list of hackers under that project.
Trifecta
Trifecta is a library for dealing with both parsing and the ancillary concerns that arise once you have a parser.
Interested in this project:
- Edward Kmett
- Doug McClean
- Paul Martel
Machine code analysis tools
Haskell could be a great platform for analyzing and reverse-engineering machine code. We already have disassemblers (x86, ARM), object format parsers (ELF, PE/COFF, MachO), SMT and bitvector solvers, dataflow analysis, etc. Let's improve these tools and fill in the gaps.
Some concrete projects in this area:
- Write bindings to radare
- Finish up the charm disassembler for ARM, and get it on Hackage
- Modify elf to support parsing relocation records
- Add support to the object format libraries for writing data structures back out to disk
- Write a format-agnostic layer on top of the object format libraries
Interested in this project:
- Keegan McAllister
- Ben Gamari (ARM support in GHC linker)
G-code backend for Diagrams
Diagrams is a nice library for declarative vector graphics. With a G-code backend, it could be used to control industrial cutting equipment.
We already have a G-code output library. For this project we would need to render Diagrams constructs to the simpler G-code commands.
Interested in this project:
- Keegan McAllister
- Ben Gamari (relevant hack: https://github.com/bgamari/GGen)
Livecoding and Music
Haskell has libraries for livecoding and music composition. We need more tutorials and tools. Focus will be on hsc3 for Supercollider.
Interested in this project:
- Tom Murphy (amindfv)
Wide fanout sequences
I'd like to build a drop-in replacement for Data.Sequence that uses wide-fanout trees, similar to the wide-fanout tries used by Johan Tibbell in recent versions of unordered containers. The hope is to come up with something that's substantially faster than lists or vectors, even for short lists, while supporting efficient (lg n) concatenation and indexing.
Interested in this project:
- [Jmaessen Jan-Willem Maessen]
Experience
Please list projects with which you are familiar. This way, people know whom to contact for more information or guidance on a particular project.
