Project: I'm implementing several machine learning algorithms in (near) base-python. I've almost finished the Naive Bayes classifier, then on to decision trees (and boosting and random forests come almost free from that), linear and logistic regression. I want to give a good depth of control and make it easy to share classifiers by writing dictionaries and exporting them as JSONs

Problem: Validating inputs is tedious

Problem: unsatisfied with package management on OS X / macOS Project: rekindle an old project of mine [0][1] Caveat: definitely works (as in I'm using it daily), but not ready for real public prime time as some meta+infra stuff still needs to be figured out. Will post instructions to get things running if some daring folks are interested. [0]: http://www.arch-osx.org / http://www.archmac.org [1]: https://github.com/a…

Not to be critical, but isn't Homebrew or Fink good enough? What features does your package manager offer that are better than these active projects?

A very valid question, I've been a Fink user, then MacPorts, then Arch OS X, then Homebrew and now Arch OS X again, and I've got some more detailed writing about this that I ought to publish one day. From the top of my head:

- PGP-signed repo db + packages (Homebrew relies solely on git SHA1s)

- package binary deltas

- building new packages is very simple thanks to ABS (Fink and MacPorts are a pain)

- doesn't write everything as a single user in a possibly multi-user machine (yes people sometimes still do share machines)

- doesn't get clobbered by software that puts stuff in /usr/local (installs in /opt/arch)

- daemons such as postgresql can run as their dedicated user

- uses sudo, so can do stuff Homebrew won't (like populate /etc/shells, /Library/LaunchDaemons, /Library/Extensions)

- makepkg builds under user, "install" with fakeroot, only pacman needs root

- synergy as an ArchLinux user, so have the benefit of a single way to manage packages

To each his own, and Homebrew is awesome (I've contributed some stuff there myself) but sometimes there are itches to be scratched: no one use case is exactly the same as another.

Project: Hosted & On-Prem fast full-text search with faceting, filtering, multiple ranking algorithms and plenty of other features.

Not yet ready for launch but built a simple demo trying to get into startupschool ( failed unfortunately :( ), which lets you search every hackernews post while letting you filter based on domain / user / story type.
